Description

The invention relates to devices for applying liquid by spraying on the surface of an object, mainly to installations for layer-by-layer processing of granular material, for example, sand-gravel mixture, sand ballast and other anti-freezing solution and applying preventive liquid to the inner surface of an open rolling stock (dump cars, gondola cars, hopper dispensers and platforms) before and during the loading of material into railway rolling stock at negative air temperatures.

The aim of the present invention is to increase the efficiency of the installation, improve the working conditions of the maintenance personnel and ensure environmental protection.

Figure 1 shows the installation in the working position, General view; figure 2 is a view along arrow a in figure 1; in Fig.Z - section H in Fig.1; figure 4 is a General view of the installation from the side of the railway track in the idle position; figure 5 is a view along arrow B in figure 4; on figb - section 11-11 on figl; Fig.7 is a cross-section TIN in Fig.4; Fig.8 is a section aa in Fig.4; figure 9 is a section IV-IV in figure 4.

The installation comprises a frame 1 of a service platform with a stand 2 mounted on it with a rotary console 3 having a manifold 4 with nozzles 5 fixed to it. The nozzles are made in the form of cylindrical bodies 6, equipped with spring-loaded spring 7 conical pistons 8 with rods 9. Collector 4 by a pipeline 10 is connected to a pump 1K for supplying an antifreeze solution through a discharge pipe 12 from a tank 13. A frame 14 with half shafts 15 is mounted above the nozzles of the collector. Guides 1 are fixed to the installation manifold 6c with slots 17. In the frame 14, holes are made above each nozzle through which the frame is connected via cables 18 to the rods of the cone-shaped pistons of the nozzles 5. The locking screws 19 fix the cables 18 in the holes of the frame 14 in a tensioned state. On the frame 1 of the service platform in the area of the initial position of the collector 4 with nozzles 5, wedge-shaped stops 21 are located on the supports 20 for interacting through the slots 17 with the axles 15 of the frame 14. The distance between the stops 21 corresponds to the distance between the slots 17 of the guides 16. Frame 14 by springs 22 is spring-loaded relative to the collector 4 and is made with a jumper 23 and a guide sleeve 24.

Springs 22 are mounted in pins 25 between manifold 4 and additional jumpers 26 with pin holes. The wedge-shaped stops 21 in the upper part are made with depressions 27. Under the collector with nozzles on the frame 1 of the service platform, a tray 28 is installed by a pipe 29 connected to the tank 13. The installation works as follows. The treatment of the inner surface of an open rolling stock and the need for bulk materials loaded into rolling stock cars with an anti-freezing solution is carried out with continuous movement of the train under the nozzles 5 (Fig. 1). The sprayed solution to the manifold 4 with nozzles 5 is supplied by the pump 11 via the discharge pipe 12 from the tank 13. From the pressure of the solution entering the cylindrical bodies 6 of the nozzles, the spring-loaded cone-shaped pistons 8 are displaced upward along the arrow A and open the nozzle outlets. In this case, the displacement of the cone-shaped pistons 8 causes the weakening of the cables 18 connecting the rods 9 of the nozzles to the frame 14. Under the action of the springs 22, the frame from moving the guide sleeve 24 relative to the branch pipe 4 and the holes of the additional jumpers 26 relative to the pins 25 also moves up , which ensures that the cables 18 are constantly tensioned. At the moment of opening the nozzle outlet openings, a spray torch formed at the outlet of the nozzle outlet processes the inner surfaces of the walls and floor of the wagons and, if necessary, layered; processing of material loaded into the cars.

After completing the processing of the last car, the installation operator turns off the pump 11, which causes a decrease in the solution pressure in the cavities of the nozzles 5. As a result, the spring-loaded cone-shaped pistons 8 are displaced by the action of the springs 7 and close the nozzle outlets, which prevents the chemical antifreeze solution from getting onto the railway track, Preventing environmental pollution. The displacement of the cone-shaped piston of the nozzles causes a corresponding displacement of the frame 14 connected via the cables 18, which provides due to the lower total stiffness of its springs 22 relative to the total stiffness of the springs 7 of the spring-loaded piston of the nozzles.

the console 3 of the installation is deployed relative to the rack 3 towards the wedge-shaped stops 21 of the supports 20 mounted on the frame 1 of the service platform. In the process of rotation of the console 3, the wedge-shaped stops 21 enter the slots 17 of the guides 16 of the collector 4 and raise the axles 15 of the frame 14. In turn, the frame connected by the cables 18 with the rods 9 of the nozzles raises the cone-shaped pistons 8 and opens the nozzle outlets , of which the liquid flows out in the nozzle bodies 6 and the manifold pipe 4 and the tray 28 and then through the pipe 29 to the tank 13.

The depressions 27 made in each of the wedge-shaped stops 21 of the cavity 27 fix the rotary console 3 with the collector 4 in the idle position after the frames 14 moved along the stops 21 of the axle shaft 15 fall into their depressions 27.
