Technological cargo wash - Allows you to remove residual dirt from the vehicle before performing a diagnostic inspection or Maintenance... It is done without the use of any chemistry. The main assistant is a high pressure apparatus (high pressure apparatus), which allows a stream of water under high pressure knock dirt off the wheels, body and cabin of a car or truck. In time, this procedure takes from 15 to 40 minutes, depending on the contamination.

Contactless cargo washing - AND are used special formulations forming an active cleansing foam. A pneumatic sprayer applies a layer of such a substance to the car and the stubborn dirt is cleared through chemical processes. It is worth noting that a properly selected foam composition is safe for paintwork and structural elements of the car. The execution time of such a wash is from 25 to 50 minutes.

In addition to the cargo wash, we have the ability to give the original appearance and passenger car... The dimensions of the car wash, as well as the high-pressure washers designed for trucks, make it possible to service sedans and hatchbacks faster and better than at conventional car washes. There is a convenient waiting area for any client with a coffee machine and the ability to charge the phone. We regularly monitor the market and guarantee the optimal price for washing your car.

Mechanical impact on contaminated surfaces at. car washing with the help of brushes, primarily rotating (rotary) ones, made it possible to improve the quality of washing, reduce the consumption of water and detergents, and reduce the time required for washing. In this regard, brush washing plants are widely used for washing cars, buses, and vans.

The use of brush installations for washing trucks limited to the fact that the bristles of the brushes, touching the protruding parts of the car, breaks out and the brushes become unusable in a short time. But due to the fact that the industry began to produce trucks with streamlined shapes, it became possible to wash them on brush installations (and to a greater extent on jet-brush installations).

Technical data of some brush washing plants produced by the Bezhetsk plant Avtospetsoborudovanie are given in table. nine.

Below are descriptions of modern as well as future brush and jet-brush installations for washing cars and buses.

Bus washing plant

The bus washing plant is manufactured by the Bezhetsk plant Avtospetsoborudovaniya. The brush washer model TsKB-1126 is designed for washing buses, mainly with carriage-type bodies.

The installation is made in the form of a frame (Fig. 25) with bearing racks, welded from pipes that act as pipelines for supplying the cleaning fluid to the nozzles. Working bodies are units of right and left paired swinging vertical rotary brushes, a horizontal brush, frames for preliminary wetting and rinsing, a pneumatic control system for vertical brushes, command controllers automatic control the operation of the installation, traffic light, hardware cabinet, container for the cleaning solution.

The units of the right and left vertical brushes, consisting of two movable tubular frames, are hingedly attached to the bearing racks. Shafts of vertical brushes with drive pulleys are mounted on the frame consoles in bearings, and on the upper consoles there are electric motors with a power of 1.5 kW-individual drive (using a V-belt transmission) of rotation of brushes with a rotational speed of 175 rpm. The frame of the horizontal brush is also mounted in the bearings of the support legs; at one end of the frame, there is a brush shaft with a drive motor, and at the other end, a counterweight.

The pneumatic control system for vertical brushes consists of two drives: the main one, which holds the brushes in a flattened state, and a drive for returning the diluted aunts to their original, initial position. Air supply to the pneumatic cylinders of the drive is carried out from the air dispensing device.

The water supply to the brushes and to the nozzles of the wetting frame and the rinsing frame is carried out from the water supply network, and in case of severe contamination, especially the lower surfaces of the bus, a solution can be supplied to the brushes detergent under the pressure of compressed air of the pneumatic system. The installation is equipped with magnetic valves to sequentially turn on and off the water supply to the individual brushes as it passes through the bus installation. Water consumption for washing one bus is about 500 liters; plant productivity - 35 buses per hour.

During the wash, the bus, moving through the installation, comes into contact with the vertical brushes, first on the left and then on the right side. IN starting position the front brush, being on the longitudinal axis of the washing installation, begins to process the front of the bus, and the rear brush processes the side walls; when the bus is advancing, the front brush moves away, forcing the rear brush to first be pressed against the side surface of the bus, and then against its rear, accompanying it when the bus is advancing. Then the brushes come back.

The return of brushes is a significant disadvantage of the installation, since the distance between the buses being processed increases, which leads to a decrease in the productivity of the installation, increased consumption water, and also increases the dimensions of the installation.

In this regard, TsPKTB. the association "Rosavtospesoborudovaniya" has been developed, and the Bezhetskiy plant Avtospetsoborudovaya-kie produces more advanced installations for washing cars and buses.

Brush installation model TsKTB-M123 for bus washing

This washing installation provides a more thorough treatment of the usually most dirty rear surfaces of a bus or van due to the fact that the brushes are delayed when washing the rear surfaces and follow the bus (van) leaving the installation.

The brush installation for washing buses and vans (Fig. 26) contains a horizontal rotary brush 16 mounted on a U-shaped frame, moving in vertical guides, balanced by a counterweight, and 6 paired vertical rotary brushes 6, suspended by means of balancers 9 on consoles 13, hingedly mounted on hollow posts 14, to the right and left of the longitudinal axis of the installation with some offset relative to each other. The balancers 9 are connected to the consoles 13 by means of full-pivot hinges 10 having a crank 5 connected by a rope 4 through a system of blocks 2 with a movable weight 3 placed in the cavity of the rack 14. The console 13 with brushes is pressed against the surfaces of the bus being washed by the spring 1.

The supply of water and cleaning solution to the collectors 12 with nozzles 11 is carried out from the pumping station. Rotation of both horizontal and vertical brushes is transmitted from individual electric motors through a gear reducer. The frequency of rotation of the brushes is 170 rpm. The automatic control over the operation of the installation is carried out by the command controller 8.

In the initial position, the weight 3 is in the lower extreme position; the balancer 9 with brushes 6 is located at an angle of 45 ° to the direction of travel of the bus. The bus, moving through the installation, spreads the consoles 13 and unfolds the balancers 9 so that the brushes on the left side are located along the side wall of the bus 7, and the load 3 rises. When the brushes come off the bus 7, they approach the longitudinal axis of the installation under the influence of the spring 1, as a result of which the balance bar 9 rotates through an angle exceeding 180 °, and the crank 5 passes the dead center. Now the load 3, when lowering, rotates the balancer 9 in the same direction in which the bus moving through the installation turned the balancer earlier. When the balance bar is forcibly rotated, the brush follows the leaving car, continuing to clean its rear surface.

The top surfaces of the bus are brushed with a horizontal brush in the usual manner. The disadvantages of the installation include the complexity of supplying electricity to the drives for rotating the brushes, which reduces the reliability of its operation.

Brush washer model M-115

The brush washing installation model M-115 (mainly for washing cars) is produced by the Bezhetsk plant Avtospetsoborudovanie. It can be equipped with a conveyor to move the processed vehicles. The installation (Fig. 27) contains collectors with nozzles in the form of frames, one mounted at the inlet, which serves for wetting before washing the surfaces of the car with a washing solution, and the other at the outlet of the installation for rinsing the washed surfaces of the car; a horizontal brush designed for treating the upper surfaces of the car, including the radiator grille, cantilevered on a swing arm - a swing arm. The pressing of the horizontal brush to the surfaces to be washed is carried out due to the difference between its masses and the counterweight, fixed at the free end of the swinging arm.

To the right and to the left of the longitudinal axis, on the base of the unit, there are racks, on each of which two consoles are hingedly mounted, turning on racks and carrying vertical rotary swing brushes designed to wash the side, vertical front and rear surfaces of the vehicle. The pressing of the vertical brushes to the treated surfaces of the car and their return to their original position occurs under the action of a spring connecting the console with the vertical brushes with the rack. The spring tends to keep the brushes in the block in a flattened state and, under the action of the counterweight, position them perpendicular to the direction of movement of the vehicle.

The rotation of the brushes is carried out from an individual electric drive with an electric motor with a power of 1.1 kW through a gear reducer.

Water (washing liquid) is supplied by a pumping station under a pressure of 4-6 kgf / cm 2; water consumption for washing one car from 250 to 350 liters. The washing installation uses electromagnetic valves that cut off the water supply to individual nodes installation when the car leaves the area of their action.

The operation of the installation mechanisms and solenoid valves is controlled by a system of command controllers, and to prevent damage to the brushes, in the event of inconsistent operation of the mechanisms and the installation conveyor, an automatic blocking is provided that stops the conveyor.

Upon entering the unit, the vehicle is wetted with a cleaning solution that flows to the nozzles of the pre-wetting frame. With further advancement, the car runs over the horizontal brush, pressing and lifting it. Then he runs into the front of the paired brushes and squeezes it to the side. In this case, the rear aunt connected with it by a rope with a counterweight is pressed against the side surface of the car, and with further movement, it moves to the rear surface of the car. When the front brush leaves the side of the car, both consoles with vertical brushes return to their original position.

The next car can only follow at 5 m intervals; such an interval is necessary in order to allow the vertical brushes to return to their original position, which is a disadvantage of this washing installation, since it not only reduces its performance, but also worsens the specific indicators for washing a car - increases the consumption of water (washing liquid), increases consumption electricity.

Brush washer with a device for blowing (drying) the car

In the described washing installation, the working bodies - vertical and horizontal rotary brushes and fans can move along the processed vehicle, which at the same time remains stationary; the washing plant is primarily intended for the washing of passenger cars. The advantage of this washing plant, developed at the TsPKTB of the Rosavtospesoborudovanie association, is its compactness (it occupies an area slightly more than the area of the car being processed), as well as the simplicity and reliability of the device for the return movement of working bodies during the blowing (drying) cycle of the car using an electromagnetic clutch.

A brush washer with a device for blowing a car (Fig. 28) contains a frame 9, which can move along rails 2 on support rollers 3. The working bodies are mounted on the frame - swing vertical 4 and horizontal 1 rotary brushes and fans 11. As a power drive pneumatic cylinders 8 and 16 are used for lifting and spreading the brushes, and pneumatic cylinders 10 are used to dilute the fans. The drive for moving along the frame rails is carried out using a two-speed electric motor 14 using a gearbox 15 that transfers rotation to the frame support roller. A limit switch is installed in the lower part of the frame. 12, interacting with a stop 13 mounted on the rails; a non-contact sensor 6 is installed on the upper part of the frame, interacting with the plate 7 of the vertical brush 4.

One of the support rollers 3 is equipped with an electromagnetic clutch 22 with a sprocket 20 connected by a chain drive 19 with a sprocket 18 of the lead screw 24 mounted in bearings 23 on the frame 9. A nut 21 is mounted on the screw 24 with a stop 26 moving in the guides 25 and interacting with: limit switch 17. The washing system is powered by a hose attached to the rack 5.

The work of a brush washing system with a device for drying a car is as follows.

The car being washed enters the washing area and stops in front of the horizontal brush 1, which is at this moment in the lower position; when the washer is switched on, it starts moving towards the car. Rotating, the horizontal brush rises and rolls onto the car being processed, and then rises to the upper extreme position; at this time, the vertical brushes diverge. The horizontal brush, after passing the car, is lowered again, and the vertical brushes converge; when the brushes converge, the contactless sensor 6 is triggered, while the electric motor 14 of the drive for moving the frame switches to reverse and the frame carrying the brushes and fans moves back. At the same time, the electromagnetic clutch 22 is turned on, as a result of which the torque from the support roller 3 through the chain transmission 19 is communicated to the lead screw 24 and the nut 21, sliding by the stop 26 in the guides 25, moves forward.

The frame with brushes and fans moves back until the limit switch 12 is triggered by interaction with the stop 13 mounted on the rails. This completes the car wash cycle; vertical brushes are spread using pneumatic cylinders 8 and 16, the supply of washing liquid (water) is stopped, fans 11 are reduced to the working position and the cycle of blowing (drying) the car begins. In this case, the frame with brushes and fans moves forward again, but at half the speed of washing. The support rollers 3, and therefore the lead screw 24 connected to one of them, rotate in the opposite direction. At the same time, nut 21 returns, and when the roller 3 makes the same number of revolutions as when returning from the washing cycle, the nut 21 with the stop 26 will press the limit switch 17. In this case, the movement of the working elements of the installation will reverse, and the electromagnetic clutch 22 will turn off and the rotation of the screw 24 will stop. The working bodies return and the cycle of blowing (drying) the car ends.

The use of the mechanism for returning the working bodies during the drying cycle reduced the duration of blowing the car by at least 20%, reduced energy consumption and increased the productivity of the installation.

Automatic brush washer

The considered brush installation (Fig. 29) comprehensively and more successfully solves the problems of mechanization and automation of washing and drying cars; it includes a conveyor (for moving cars through the installation), along the longitudinal axis of which two pairs of vertical rotary brushes and one pair of paired swing brushes 6 are symmetrically mounted on the right and left for washing the front, side and rear surfaces of the car. For washing the top of the car, there is a horizontal rotary brush "8, mounted on the gantry 9.

At the beginning of the installation, there is a shower frame 10 with nozzles for preliminary washing, and at the end, the same shower frame 5 for the final rinsing of the car; they are part of a frame made of pipes that serve as pipelines for supplying cleaning fluid. At the end of the washing post, fans 3 are mounted on a U-shaped frame for blowing off the car after washing.

For washing the wheels, a device is installed on the right and left of the conveyor (not shown in the figure), and for washing the bottom (bottom) of the car, the installation is equipped with devices 19 and 20. The washing liquid is supplied by two pumping stations, one of which is connected to the water source, and the second to the main hot water, which is mixed with water (washing liquid) only for washing the underside of the car, and there is an automatic thermostat to ensure the desired temperature; water supply to the nozzles is carried out under a pressure of up to 16 kgf / cm 2 through a comb and pneumohydraulic valves, and for washing the car bottom, the washing liquid is supplied under a pressure of up to 40 kgf / cm 2.

The conveyor is driven by a drive station 1, the drive sprocket of which is covered by a traction chain 2, which receives tension from the same sprocket 14 of the tensioning station. A gearbox is installed in the drive station, which provides a change in the speed of movement of the car through the washing installation from 1.5 to 9.0 m / min,

Rotary washing brushes are made with a plastic bristle carrier. Vertical brushes are mounted on pipe racks 7; in the upper part of the rack, supporting vertical and horizontal brushes, with the help of couplings are rigidly connected to each other by transverse 18 and longitudinal pipes 17 through which washing liquid is supplied to the collectors of all brushes.

Rotary brushes have the ability to rotate at an angle of 90 ° towards the longitudinal axis of the conveyor to press them against the washed surfaces using counterweights. Drive unit. brushes are carried out from electric motors with a power of 1 kW each; the frequency of rotation of the brushes is 120 rpm. Paired swing brushes 16, designed for processing the front and rear surfaces of the vehicle, are pulled together by a rope using a 12 kg load. They return to their original position under the action of a 15 kg load suspended on a rope attached to the brush frames.

The control of the installation is fully automated, but it can be switched to remote control from the control panel located in the operator's cabin 11.

The installation control complex includes a traffic light 13 installed before entering the washing station and mounted before entering the washing installation a searchlight 12 and a photoresistor 21 interacting with it to turn on the installation mechanisms, as well as a searchlight 4 and a photoresistance 15 interacting with it to turn on the drying installation -blowing the car after washing.

For washing the underside of the car, the installation uses a device in the form of a manifold 3 with oscillating vibrating nozzles 2 (Fig. 30). The collector is connected to the pipeline of the pumping station 7 by means of a flexible hose 1. To communicate the oscillating-vibrating motion to the collector with nozzles, there is a vibrator 6 with an electric drive 5, connected by means of a rod 4 to the collector 3.

The device with vibration-swinging nozzles provides better washing of the vehicle underbody. In addition, an improvement in the quality of washing is also achieved due to the fact that this device is connected to a pumping station that supplies hot water; the use of hot water is especially important in the cold season, when freezing forms on the bottom of the car, and the pumping station supplies hot water from an automatically operating thermostat according to the specified parameters.

The automatic control circuit of the unit operation (Fig. 31) includes control panel 1, control panel 2, control unit 3 and power supply 4. Magnetic starters 5 are mounted on the control panel (for each electric motor of the washing installation), a fuse and a switch, as well as electro-pneumatic valves 6 for each pnezmo-hydraulic valve 7 of the power supply system of the installation with washing liquid and water.

Magnetic starters and electro-pneumatic valves are controlled from the control panel (via program switches P of the control unit) automatically or manually. Both in the first and in the second case, the installation units are switched on by one button "Start" mounted on the control panel and turning on the supply of electric current from the power supply unit.

The power supply contains three transformers and two rectifiers. One of the transformers - step-down - is designed for photo relay floodlights. The second transformer with rectifier has an output voltage of 24 V; it is designed to supply relays and electro-pneumatic valves. The third transformer with a rectifier has an output voltage of 150 V and is designed to power the photo relay and time relay. Time relays allow you to adjust the time delay from one second to two minutes, which ensures timely shutdown of the units at any selected conveyor speed. Thus, an economical, expenditure of both is ensured. washing liquid and electricity.

The arrival of cars on the conveyor of the washing installation at a predetermined interval is regulated by two traffic lights (installed before entering the washing post and before entering the conveyor), one of which is controlled from the light relay of the traffic light, and the other from the contacts of the light relay of the installation.

The described control unit works efficiently and does not require any repairs for several years; this is also facilitated by the fact that the electric currents in the relay contacts are insignificant.

From the foregoing, it can be seen that the automatic control scheme of the washing installation is simple, it uses units and parts of industrial production. As a rule, one operator supervises the operation of the washing installation, whose task is to set the program on the control panel and initially, turn on the conveyor with the selected optimal speed, depending on weather conditions, and then only monitor the normal operation of all units. 72

Before entering the washing station, a traffic light is installed that acts automatically and provides a safe distance (within 1.5-2.0 m) between the cars following to the washing plant.

When the traffic light is green, the car enters the conveyor, stops and upon further movement with the help of the conveyor crosses the beam of the searchlight 12 (see Fig. 29), illuminating the photoresistor 21, which ensures that the electric drives of the rotary brushes are turned on and the valves letting through the washing liquid (water) from the comb are opened for washing shower frames and brushes, as well as for washing the car underneath. As the car passes, if another car follows it, the electric drives of the rotary brushes will be switched on at a set interval, and the valves for supplying the washing liquid (water) are open. When the car approaches the drying (blowing) installation, it will cross the beam of the next floodlight, causing a darkening of the photoresistor interacting with it, which provides sequential, at a certain interval (up to three seconds), the inclusion of all three blower fan motors, thereby eliminating overloads of the power grid arising from a large starting current. After vehicles pass through the blower unit, the fan motors are automatically turned off. When passing through the car wash system with an interval of less than 2.5-3.0 m, all units of the unit work continuously, providing high-quality washing and effective airflow after washing.

The throughput of the washing plant reaches 45-50 vehicles per hour.

High technical level The washing installation is confirmed not only by the experience of its operation, but also by the fact that the main units and devices of the installation, which underwent modernization and reconstruction during the operation, were recognized as inventions and eight copyright certificates were issued for them.

In 1975, this washing installation was exhibited at the Exhibition of Achievements of the National Economy of the USSR and received the highest rating - the Gold Medal.

Cantilever wash unit for cars and buses

A feature of the installation is that, in addition to a pair of vertical rotary brushes, fixed on the base of the installation, there is another pair of vertical rotary brushes suspended with the ability to move on cantilever beams, mounted on the crossbar of the U-shaped frame. This improves the quality and shortens the time it takes to wash the car.

Installation with cantilever beams for washing cars and buses (Fig. 32) contains a U-shaped frame 6, reinforced on the base, on the crossbar of which a hinge 5 is installed, in which cantilever beam 7 with a movable carriage is attached I carrying a rotary vertical brush 10 with an electric drive 11 The carriage moves with a brush along the cantilever beam under the influence of the load 2 and in the initial position is closer to the hinge 5. The cantilever beam 7 is rotated using the power drive 4. The cantilever beam has switches 8 and 3.

On the opposite side of the installation, a second swivel cantilever beam 19 is attached to the crossbar by means of a hinge 18, on which a carriage 13 is installed, carrying a rotary brush 14 with an electric drive 15.

Side rotary brushes 12 and 17 are mounted on the racks of the base of the installation. In addition, a horizontal rotary brush 16 is mounted at the end of the installation for washing the upper surfaces of the vehicle.

The cantilever beam 7 has two locking positions: initial position I and position II. In position I, the beam 7 is deflected forward from the perpendicular to the longitudinal axis of the installation, that is, it forms an obtuse angle α with the longitudinal axis. In position II, the cantilever beam is tilted back and forms an acute angle β with the longitudinal axis. Movement - the rotation of the beam from position I to position II is carried out by the power drive 4 and begins after the carriage 9 approaches the switch 8, and the movement from position II to position I begins after the carriage 9 approaches the switch 3.

When the cantilever beam 7 is in the initial position I, the car 1, moving in the direction of the arrow A, moves the brush 10 in the direction of the arrow B. In this case, the front of the car is washed. When the carriage reaches the switch brush 8, the cantilever beam rotates through an angle γ. During the movement of the cantilever beam 7 from position I to position II, the brush moves towards the moving vehicle (in the direction of arrow 5), washing its side part. At the end of the washing of the side of the car, the carriage 9 with the brush 10 under the action of the load moves in the direction of the arrow D and carries out washing the rear of the car, after which the carriage 9 comes to the switch 5; cantilever beam 7 moves from position II to position I.

The disadvantage of the installation is some complexity of the kinematic scheme of the action of the brushes installed on the cantilever beams, and the high energy consumption of the installation, which has five driven rotary brushes (which also increases the operating costs of maintaining the installation).

Cantilever brush washer

In the described brush washing installation, due to the fact that the cantilever beams carrying the vertical brushes on the carriages are made spring-loaded, no drive is required to turn them, but the energy of the vehicle moving through the installation is used and, moreover, no counterweights are required to press the brushes against the surfaces to be washed. The advantage of the machine is that it has only three rotary brushes.

The installation (Fig. 33) contains racks mounted on the base, on which cantilever beams are installed with an inclination towards the vehicle being washed by means of hinges.

Moving carriages are mounted on the beams, carrying vertical rotary brushes, mounted on the carriages by means of a hinged suspension. Each cantilever beam is held in its original position by a spring connected to the strut. With the help of a rope through the block and the hinge-linkage system, the cantilever beam is connected to a pedal interacting with the wheel of the vehicle being washed. A retainer is installed on the cantilever beam, connected by means of a rope to a hinged lever. The racks are equipped with a limiter interacting with the lock.

The horizontal rotary brush (not shown in the figure) is mounted on a U-shaped portal frame, fixed on the base. Collectors with nozzles are mounted on the cantilever beams, the portal frame and on a special wash frame. At the entrance and exit from the washing installation, controllers are mounted that interact with the vehicle being processed.

When entering the washing installation, the car presses on the leash of the controller, while the drive for rotating the brushes is turned on and the washing liquid is supplied to the nozzles. The vehicle passes under a horizontal rotary brush that washes the front tops and rear surfaces and then travels to the vertical rotary brushes. By pressing on the rotating vertical brush, the car thereby deflects the cantilever beam forward along the path, while the brush rolls away from the center of the car due to the reactive forces of rotation. The front and then the side surfaces of the vehicle are washed; moving further, the car runs over the pedal with the wheel. From the pedal, the force is transmitted through the hinge-lever system and the rope to the cantilever beam, which at the same time turns into the flushing position and is secured with a latch. The articulated suspension of the vertical brush ensures a more uniform adherence to the surfaces of the vehicle being washed. When the car will pass a vertical brush, the last along the inclined cantilever beam begins to move towards the center of the washing system. Since the cantilever beam is thus rotated after the car, the brush follows the car, washing its rear surfaces.

When the car leaves contact with the brush, the brush reaches the end of the cantilever beam. In this case, the carriage presses on the lever, the movement of which is transmitted through the rope to the latch, as a result of which the cantilever beam moves back to its original position.

Leaving the washing station, the car presses on the leash of the controller, turning off the drives of the washing installation,

Brush washer with pendulum horizontal brush

The design feature of this brush washing installation is that the horizontal rotary brush is made of pendulum, swinging in a vertical plane, which increases the productivity of the washing installation and improves the quality of washing.

A brush washer with a pendulum horizontal brush (Fig. 34) contains a U-shaped frame with struts 6 and 18, on which a transverse beam 10 is fixed. horizontal brush 3; the latter is driven into rotation by an electric motor B through a gearbox 4. Side vertical brushes are mounted on the posts 6 and 18 of the frame (not shown in the figure). The brush, electric motor, gearbox, frame and sliders are partially balanced by weights 1 and 2, which are connected to the sliders by means of chains put on the sprockets 11 and 8. The shaft 9 of the sprockets 11 and 8 is fastened through the electromagnetic clutch 12 and the gearbox 13 is connected to the electric motor 14. A shock absorber 75 is installed between the frame 17 and the slider 16. A switch 19 is located on the slider 16, which interacts with the frame 17 when the horizontal brush is deflected forward along the motion of the vehicle being processed by a certain predetermined angle a or by an angle greater than the angle α. The total weight of the balancing weights is adjusted so that the horizontal brush is applied to the upper surfaces of the vehicle with a predetermined limited force.

In the initial position, the horizontal brush is at the bottom. Moving in the direction of arrow A, the car 20 comes into contact with the front part of the horizontal brush, which, together with the pendulum frame 17, moves forward; when the pendulum frame is deflected at a given angle a, the switch is triggered; simultaneously turning on the electric motor 14 of the drive for displacing the frame 17 in the vertical plane and the electromagnetic clutch 12 connecting the output shaft of the gearbox 13 to the shaft 9 of the sprockets 8 and 17. In this case, the frame with the horizontal brush moves up until the impact of the processed vehicle on the horizontal brush stops in the direction of arrow A. When the horizontal brush is rotated in the direction of arrow B during washing of horizontal sections of the car surface (hood, roof, trunk lid), the pendulum frame with the horizontal brush is deflected in the opposite direction by angle B. When the car passes through the wash post, the horizontal brush is lowered (with the displacement drive disconnected), processing back car. The brush is held against rocking by a shock absorber 15.

The disadvantage of this installation is the complexity of the device of the brush control drives, and the use of an electromagnetic clutch (in conditions of high humidity) reduces the reliability of the installation.

External washing system for articulated buses

A feature of articulated buses, for example of the Ikarus type, is that protruding cross members are installed on their roof, preventing washing of the bus in conventional washing installations. In this regard, the TsPKTB of the Rosavtospesoborudovanie association has developed an installation for the external washing of articulated buses, which has a mechanism for lifting (hanging) a horizontal brush, which ensures that the roof is washed with a conventional horizontal brush.

Installation for external washing of articulated buses (Fig. 35) contains a vertical frame 6, which is mounted horizontal 7 and vertical swinging rotary brushes 9, driven by electric motors through a gearbox.

A bracket 13 is mounted on the frame 6, on which a figured two-armed lever 2 and a cantilever lever 3 are mounted in bearings by means of an axis. These levers are connected by means of a spring 14 and a rope 11 thrown over block 12, which is mounted on the bracket 10 of a two-armed lever 2.

The washing liquid is supplied to the nozzles through the collectors 1; the washing system is switched on by command controllers 5.

Bus 8, when moving across the washing bridge, pushes the vertical rotary brushes that process the front and side, and then the rear surfaces; at this time, the horizontal rotary brush processes the bus roof, and when the first protruding cross member 4 of the bus roof hits the lower end of the two-armed lever 2, the latter turns, picks up the frame of the horizontal brush and lifts it. At the same time, the cantilever lever 3 rotates. With further advancement of the bus, the second protruding cross member of the cover pushes onto the cantilever lever 3 and rotates it, while the spring 14 is stretched and when the first cross member 4 comes off the two-armed lever 2, it is held in the raised position by the spring 14. When the second cross member descends the bus from the console arm 3 the device for hanging the horizontal brush returns to its original position; and the brush itself goes down. This concludes the articulated bus wash cycle.

Installation of the M-205 model for washing car wheel rims

Installation of model M-205 for washing wheel rims of passenger cars, produced by the Bezhetsk plant Avtospesoborudovanie (Fig. 36) contains two identical washing mechanisms, mounted on a frame on both sides of the longitudinal axis of the washing station. Each washing mechanism is made in the form of five rotary, disk-type nylon brushes installed in one row on the frame with their ends downward, with an inclination of the axis of rotation relative to the floor surface. The brush rotation is driven by an AOL2-34-4 electric motor (3 kW) through a gearbox and chain drives. The frequency of rotation of the brushes is 400 rpm. Tubular collectors with nozzles are used to supply the cleaning liquid to the brushes.

Electric drives of brushes and solenoid valves are controlled by input and output controllers.

The pressure of the water (washing liquid) supplied to the installation from the pumping station is from 4 to 6 kgf / cm 2; water consumption per car 45-70 liters.

This installation can be installed in combination with any brush or jet installation for washing cars. The work of the installation for washing the rims of the car wheels occurs simultaneously with the operation of the main washing installation.

The disadvantage of the installation is that the brushes have only right-handed (in one direction) rotation, as a result of which complete washing of the section of the wheel disk near the valve protruding from the disk is not ensured.

Car wheel washer

This device, successfully operated in the Krasnopresnenskaya motor depot in Moscow, provides rotary brushes with opposite rotation, which significantly improves the quality of wheel washing.

The device (Fig. 37) contains two rows of five rotary brushes, each - left 2 and right installations, in case of entering the car wash close one after the other, there is a switch, when turned on, the electric drives are not turned off and the water supply does not stop.

In each bearing housing there is a shaft 17, in the lower part of which rotary brushes 16 are fixed, and in the upper part there are sprockets 5, 6, 7, 9 and 10. The chain 8 is put on the indicated sprockets and the sprocket of the pulley 15, and in the sprocket 5 the left chain is covered part, in the sprocket 6 right, in the sprocket 7 left, etc. For tensioning the chain is a spring-loaded tension roller 13.

Each rotary brush 16 consists of four annular plastic elements 19, into which a bristle of fine nylon filaments is poured; ring plastic elements are fixed on the shaft 17 by means of two flanges 23 and 22, one of which is fixed on the shaft 17. In turn, the ring plastic elements 19 are also fixed to each other and to the flange 23. Rotary brushes 16 are fixed on the shaft 17 by the bolt 21 and washer 20.

When the wheels pass along the guides 1 and 4 past the rotating brushes, the cavities of the wheel disks are washed on both sides, in addition, the bristles of two adjacent brushes (during rotation) are rolled, which sharply reduces the energy loss for friction between the brushes and provides a better washing of the wheels at the chamber valve pneumatic tires due to the rotation of the brushes in different directions.

Mobile brushing machine for car wash

In cases where open parking lots are created, it becomes necessary to perform on them daily service, the main content of which is washing and cleaning. In this regard, the most expedient is the use of mobile washing installations. The technical problem of creating a mobile washing installation based on a watering and washing machine, for example, the PM-130 model (Turbovskiy machine-building plant), has been successfully solved. All equipment of the washing installation (Fig. 38) is hinged, mounted on the tank 8 of the irrigation machine 12 using water and hydraulic pumps and the brake pneumatic system of the chassis of the machine. On the platform 9, mounted on the tank, a pneumatic lift 10 is rigidly mounted, carrying a console 11, at the free end of which a spring-loaded brush holder 13 is hinged, made in the form of a frame 4 with a pipeline 2 having nozzles for spraying washing liquid. Swinging vertical rotary brushes 3 are mounted on the frame 4; the brush holder is made rotatable in the bushing 5, fixed to the tank by means of detachable hinges 6. One of the rotary brushes is driven directly by the hydraulic motor 15, connected by a pipeline to the hydraulic pump; the other brush is driven into rotation by the same hydraulic motor, but by means of a V-belt transmission 14.

In the transport position, the frame with the brushes is hung out using a pneumatic lifter 10 and turns to the rear end of the tank, on which the hinges 6 are fixed by means of clamps 7.

Upon arrival, for example, at the open parking lot of buses, the locks 7 are released, the console 11 with the rotary brushes is turned into the working position and with the help of the pneumatic lifter 10 it is lowered to the level of coverage with the brushes of the bottom of the bus; after that, the frame 4 is fixed by means of detachable hinges 6 on the side of the tank. The bus to be treated approaches the installation until the front part 1 contacts the rotary brushes, after which the pump for supplying the washing liquid from the tank to the nozzles of the pipeline 2 is turned on, and then the brushes are turned on. The bus passes along the washing plant - it is washed on the right side, then the bus turns around and also passes along the washing plant - as a result, it is completely washed.

There is no bus that we have not laundered!

Thanks to the available modern specialized washing complex and highly qualified personnel, we will cope with any task. Our craftsmen know all the intricacies of polishing buses of various types and sizes. It should be noted that adherence to the correct sequence of external washing of the bus is a guarantee of its impeccable appearance.

The primary treatment with a water jet is carried out in order to remove coarse dirt, particles of road dust, sand, reagents and insects. Indeed, in the future there will be a thorough treatment with special brushes, and if this is not done, then the formation of small scratches on the body cannot be avoided. It is important for the washer to scrupulously check whether he has completely removed large dirt particles or not before proceeding to the next operation.
Then there is a process of "soaping" or creating a stable layer of special foam on the body of the bus. IMPORTANT! Here it is necessary to use only high-quality and certified auto chemistry, so that the foam removes dirt and does not leave traces of the so-called stains.
Then the specialist, using sliding brushes, removes traces of dirt and various chemical stains that are on the paint-lacquer coating of the bus. The special device of the telescopic brush and the optimally matched bristle stiffness will provide glossy cleanliness in any, even hard-to-reach places.
Next, the thick foam layer is washed off using modern non-contact high pressure washing machines. Without their use, it is impossible to completely wash off auto chemicals from the bus, and the remaining soap solution can harm the paintwork.
