Description

The utility model relates to the field of railway transport, namely to the field of railway hopper cars.

Hopper cars are bunker freight cars.

Hopper wagons are designed for transportation of bulk cargo and relate to self-unloading wagons according to the method of unloading. The main design feature of such cars is a body made in the lower part in the form of a hopper and having end walls, along which the cargo slides to the unloading hatches. Depending on the arrangement of the bunkers and the location of the unloading hatches, hopper cars can provide unloading into the space between the rails or on both sides of the rail gauge.

Hopper wagons are built indoor - for the transport of goods that need protection from atmospheric precipitation (cement, grain, fertilizers, sugar, etc.), or open (gondola wagons) - for the transport of crushed stone, coal, peat, ore, gravel and others. The former are used on the main railways, the latter on the railways of industrial transport. All types of hoppers, as a rule, are built with four axles, with typical running gears, brakes, couplers and other devices.

Known railway hopper cars models: 19-752, 19-758, 19-923, 19-953, 19-969.

Known combined hopper car (patent No. 2249519, IPC B61D7 / 00, B61D 7/00, publ. 04/10/2005), containing a running gear, a bunker compartment and adjacent to the ends of the storage chamber of the transported material with doorways for entry of autocar, rigidly connected with the frame of the car equipped with pivot beams, and it is equipped with four rotary struts, the upper end of each of which abuts against the junction of the boundary wall between the hopper compartment and the storage chamber of the transported material and the upper trim of the side wall gon, and the lower one rests on a pivot beam, forming a truss-type assembly with a power hopper and a frame.

Known four-axis all-metal hopper (patent No. 2273576, IPC B61D 7/00, B61D 17/04, B61D 17/12, B61D 39/00, publ. 04/10/2006), the closest in technical essence to the claimed device and adopted as a prototype containing the body of a bunker-type carriage supported by a frame containing a spinal beam and two pivot beams resting on the running gear, which consists of two biaxial bogies. The frame is connected with inclined racks and vertical racks of the side walls of the body.

The disadvantages of the known hopper cars are the unreliable design of the side walls of the body, in which there is no reinforcement of the end parts, as a result of which an incorrect distribution of longitudinal and vertical forces can occur.

The technical problem to which the present utility model is directed is the elimination of the aforementioned disadvantages of the prior art.

The technical result of the claimed technical solution is to increase the reliability of the hopper car by reducing the voltage level at the points of attachment of the side walls of the body to the side and pivot beams of the frame.

As a result, improved operational characteristics of the car are provided, namely: the total body weight of the hopper car is reduced, the reliability of the body is increased by optimizing the load distribution through the side beam of the frame to the pivot beam.

What is new is that each side wall of the body of the hopper car from each of its edges is equipped with power structures in the form of rectangular triangles formed by an extreme vertical strut, an inclined strut and a side beam of the frame.

The inventive device is illustrated in the figures:

FIG. 1 is a general view of a hopper car;

FIG. 2 - power structure of the side wall of the body of the hopper car;

FIG. 3 is a fragment of the lower part of the power structure in FIG. 2.

The inventive device consists of the following elements:

1 - body;

2 - automatic coupler equipment;

3 - brake equipment;

4 - vertical struts of the side walls of the body;

5 - extreme vertical rack of the side wall of the body;

6 - side beam of the frame;

7 - an inclined rack of a side wall of a body;

8 - pivot beam of the frame.

The hopper car contains a coupler 2 and brake 3 equipment mounted on bogie-type chassis trucks 1, supported by a frame containing side 6 and 8-pin pivot beams. The side beam 6 rests on the pivot beam 8, i.e. during operation of the car side beam 6 transfers the load to the pivot beam 8.

Body 1 may contain two or three rows of silos in the inter-body space.

Each of the side walls of the body 1 contains vertical struts 4 located at an equal distance from each other, and power structures in the form of a rectangular triangle located at the edges of the side wall.

At the same time, the power structure located on each edge of each side wall of the body 1 includes rigidly interconnected, for example, by welding, an extreme vertical strut 5, a side beam 6 horizontally mounted on the carriage frame and an inclined strut 7. Moreover, the inclined strut 7 forms with the lateral beam 6 angle to the horizon α = 60 ° -89.9 ° (Fig. 2).

The inventive device is also characterized in that the inclined rack 7 is mounted directly on the side beam 6, which lies on the pivot beam 8, in contrast to the well-known hopper cars in which the inclined rack is mounted directly on the pivot beam.

The inventive device is also characterized in that the working section of the side beam 6 is located directly in the zone of its exit beyond the pivot beam 8 and does not contain, in contrast to the analogues of welds, which are significantly less reliable.

During operation of the railway hopper car, the side wall of the body 1 experiences a variety of alternating longitudinal and vertical loads. The proposed power structure (Fig. 2) in a hopper car allows to optimize the transmission of these loads through the side beam 6 to the pivot beam 8, thereby reducing the voltage level at the points of attachment of the side 6 and pivot beam 8.

These positive effects have a favorable effect on the overall performance of the car.
