SU207954A1 - RAILWAY CAR OF TYPE “HOPPER” - Google Patents

Description

Self-unloading vehicles are known, on the inner surface of the body of which an elastic inflatable casing is placed, connected to a pressure source during unloading of the transported material.

The peculiarity of the described carriage of the type "hopper with pneumatic drive for opening the covers is that the inflatable casing is made as separate interconnected cushions that are connected to the pipeline connected by means of a pressure retractor and a two-way valve with an air line supplying the pneumocylidiri of the opening of the caps hatches. The two-way valve is provided with a shift knob, which is connected to the hatch cover by means of a pull. In a car of this design, the cushions are automatically and uniformly filled with air when opening the manhole covers. Pillows can be made in the form of a cone, with the base facing upwards, which, when filled with air, increases the angle of rolling of the load. The described padding is intended primarily for the transport of apatite concentrate.

same, with air-filled pillows, in longitudinal section.

On the inner surface of the walls 1 and the gable bottom 2 of the Kuzwa car, there are associated inflatable cushions 3, for example, made of rubber-fabric materials. The cushions are connected to pipe 4, which is connected to the air line 7 by means of a pressure regulator 5 (a reducer or a limit pressure valve) and a two-way valve 6, the latter feeding pneumatic cylinders 8 that drive the lever system 9 of the arms of the unloading hatches 11 of the car. The switching handle 12 of the crane is connected to the lid 13 with the cover 10.

When the manhole covers are closed, the crank handle is in position I, and pipe 4 is connected to the atmosphere. During the supply of compressed air through the air duct 7 to the upper cavities of the cylinders, the rods 14 move forward: and pull the lever system and the associated covers, which turn and open the hatches; the handle of the crane with the help of a gig takes the position of //, the valve communicates the pipeline 4 with the air duct 7, and the air begins to fill the pillows simultaneously over the entire surface of the kusava. In this case, the cushions squeeze out the material being unloaded from the walls of the body, and it falls into the open discharge hatches.

When airbags are filled with air, the adhesion of the particles of the cargo to each other is destroyed, and the tightly tensioned and convex surfaces of the pillows ensure their rolling. The rolling up of cargo particles is enhanced by the fact that the cushions take on a conical shape when filled, increasing the angle of rolling. So there is a complete cleaning of the car from the remnants of the cargo.

After the unloading of the hatches is completed, the crank handle returns to position /, and the air from the pillows goes into the atmosphere.

Subject matter

1. A railway carriage of the type "hopper with a pneumatic drive of opening the covers of the unloading hatches, on the inner surface of the body of which an inflatable elastic casing is placed, characterized in that, for the purpose of uniform and automatic filling of the casing and unloading of the car, there is a casing in it. made in the form of separate interconnected pillows that are connected to a pipeline connected to an air duct supplying the actuator pneumatic cylinders by means of a pressure regulator and a two-way valve equipped with a handle oh switch connected to the hatch with the hatch cover.

2. Carriage of claim 1, characterized in that, in order to increase the angle of rolling of the load, the cushion is made in the form of a cone, with the base bent up.
