(54) MACHINE FOR WASHING WALLS

one

This invention relates to machines for cleaning and washing walls, mainly tunnel walls.

A known wall washer containing a flap lifting mechanism mounted on the base chassis, means for ensuring the brush rotates about its vertical axis and an affinity for supplying washing liquid to the surface of the brush.

brush movement; FIG. A-A, FIG. one.

The wall cleaning machine contains a horizontal displacement mechanism of the brush 3 mounted on the side members 1 of the base chassis 2, consisting of horizontal guides 5 fixed with the help of slide 4, on which the carriage 6 is mounted for movement; the lifting mechanism of the brush 3, containing

mounted on the frame 7 vertical guides 8, carriage 9, rigidly connected with the brush 3 and mounted on the vertical guides 8; and means for changing the angle of inclination of the frame 7, made in the form of a power cylinder 10. The frame 7 is mounted on pillars 11 and can be moved by means of a power cylinder 12. On the frame 7 a pivot sprocket 13 is fixed. The chain 14 is connected with a carriage 9 and an asterisk 13.

The upper end of the frame 7 is rigidly connected to the piston of the power cylinder 10, and the lower end through the post 11 is pivotally connected to the carriage 6. The power cylinder 15 is the drive of the carriage 6.

The carriage 9 is rigidly connected to the axis 16, on which the brush 3 is fixed by means of the brackets 17. The brackets 17 are connected by a spring 18 to the axle 16 fixedly mounted on the axle 16. The axle 16 is fixed to the axle 16, which interacts with the brace 17. The bar 3 has the drive from the motor 21. The machine can also be equipped with nozzles 22 for supplying water to the surface to be cleaned. The machine works as follows. The base 2 moves along the wall to be cleaned. With the help of the power cylinder 15 and the carriage 6, the required departure of the brush 3 is established, due to the construction of the section of the road adjacent to the wall (presence of curb stone, its width, various objects located near the wall). Using a force cylinder 10, the inclination of the brush to the vertical is adjusted corresponding to the inclination of the wall. With the help of the ram 12, the necessary brush raising or reciprocating movement in the vertical direction is carried out. The power cylinder 12 moves the frame 7 together with a turning star 13

The chain wheel 14 enveloping the sprocket causes the carriage 9 to move along the vertical guides 8, while the distance of the carriage 9 moving is twice the movement of the rod of the power cylinder 12. Rotation of the brush 3 is carried out with the help of a hydraulic motor 21. The swivel arm 17 and the spring 18 provide copying brushing 3 wall surfaces while moving the base chassis. The maximum deviation of the brush 3 is limited by the stop 20. When the machine is in operation, water from the nozzles 22 is supplied to the zone of the brush.

The proposed machine provides the best technological performance: greater cleaning height and the ability to clean walls located at different angles to the vertical. In addition, the proposed design reduces the load on the lifting mechanism by reducing the weight of the machine.
