Description

(54) INSTALLATION FOR CLEANING THE INTERNAL AND EXTERNAL EXTERNAL RAILWAY CARRIAGE on the movable carriage 21 with a nozzle head 22 located on it, which is connected to the jet device via a hose 23. The movement of the rotary base, the truss and the guide frame is carried out with the help of reversible electric motors 25, 26 and 27. The installation works as follows. . To clean the inner surfaces, for example, the body of an all-metal passenger car, the carriage 7 is set along the axis of the track 3. The farm 19 and the guide frame 2 O are set so that ax lengths are parallel to the longitudinal axis of the boom 14, i.e. parallel to the axis of the track. 3.. ,, The body, completely disassembled, is fed into the chamber until the front part of the cantilever boom enters into the inside of the body through the end door opening. A cantilever boom with a nozzle head is positioned to handle one of the side walls of the body so that the longitudinal axis of the swinging truss is perpendicular to the work surface, and the longitudinal axis of the guide frame is parallel to it. The operator turns on the jet system, after which the mixture of the working fluid, such as steel shot or sand: a and compressed air, is directed along the hose 23 to the head 22. At the same time, the transfer mechanisms are turned on; trolleys 5 - with car 4 on the way 3; the carriage 21 with the head 22 on the frame 2O. As a result of the simultaneous movement of the carriage with the nozzle and the nozzle car, the head sequentially processes the corresponding floor or ceiling of the car body. After the termination of cleaning of the box 5, the mash-4 is smeared, the swing frame is installed. parallel to the axis of the boom, the swivel base, the swivel base rotates PA 9O, and the truss 19 returns to the working position to process another wall, the floor of the ceiling. For external treatment of the body, the carriage 7 is set to one of the positions (see Fig. 2, position 1 or 11) i, and then the gun is fed into chamber 1 so that the front end of the car stands against the end of the cantilever boom. After that, the operator in: switches on the corresponding electro-i engine, sets up the farm 19 perpendicularly, and the frame 20 - in parallel with the surface being machined. To handle the roof, the cantilever boom is lifted using a Nuren6 Grinder scissors mechanism, and a controlled device with a nozzle head is the same as when cleaning the floor. To clean the shaped surfaces of the wagon, the operator sets in motion the mechanisms for moving the base 17, the truss 19, the guide frame 2O, the carriage 21, the heat sink 7, which makes it possible to treat all surfaces of the car without the presence of a person in the work area. shade Installation for cleaning the interior and exterior surfaces of the rail. car, containing a self-propelled carriage with a cantilever boom and a nozzle head, so that, in order to increase productivity and improve working conditions, a pivot is mounted on the free arm of the cantilever boom, on an axis parallel to the boom axis the base, the carrier niee is a hinged-swivel truss fixed to it at one end, to the other end of which a guide frame is hinged and equipped with a movable carriage on which the head is placed.
