Description

This utility model relates to transport, in particular to railway cars.

From patent RU 129470 U1, IPC B61D 7/06, publ. 06/27/2013 (prototype) a hopper car is known, containing a frame, undercarriages, a body equipped with bunkers in the lower part and resting on undercarriages through the frame, and automatic couplers.

The technical problem inherent in this device is the low linear load, since the length of the car is used irrationally due to the lack of loading in the cantilever parts of the hopper car.

The technical result of the claimed utility model is to increase the linear load of the hopper car and ensure the transfer of forces from the cargo placed in the body to the frame by connecting the cantilever bins to the end beams of the frame and by moving the end parts of the cantilever bins and the parts connected to them beyond the front stop end beams. This increases the efficiency of using the length of the hopper car due to the possibility of loading cargo into the cantilever parts of the hopper car, and also ensures uniform pressure on all bogies of the car.

The specified technical result is provided by a hopper car containing a frame, running bogies, a body equipped in the lower part with bunkers and resting on the running bogies through the frame, and automatic couplers with front stops, and the cantilever parts of the body are equipped with cantilever bins connected to the side parts of the end beams frames, wherein the cantilever bins are carried out by the outer end walls relative to the front stops along the longitudinal axis of the hopper car.

The side parts of the end beams can be moved relative to the front stops along the longitudinal axis of the hopper car.

Console hoppers can be installed on the end beams, in particular through the longitudinal beams.

The offset value of the outer end walls of the cantilever hoppers relative to the front stops can be from 1 (preferably 5) to 400 (preferably 300) mm.

The claimed utility model differs from the prototype in that the cantilever body parts are equipped with cantilever bins connected to the side parts of the end beams of the frame, and the cantilever bins are taken out by the outer end walls relative to the front stops along the longitudinal axis of the hopper car; the side parts of the end beams can be moved relative to the front stops along the longitudinal axis of the hopper car; cantilever hoppers can be mounted on end beams; cantilever hoppers can be installed on the end beams through the longitudinal beams. The offset value of the outer end walls of the cantilever hoppers relative to the front stops can be from 1 (preferably 5) to 400 (preferably 300) mm.

These distinguishing features, taking into account their materiality in relation to the technical result, make it possible to assert that the claimed utility model complies with the criterion of patentability of the utility model "novelty".

The proposed utility model is illustrated by graphic material, where:

in fig. 1 - hopper car, general view;

in fig. 2 - console part of the hopper car, axonometric projection;

in fig. 3 - console part of the hopper car, bottom view.

The hopper car includes undercarriages, a frame and a body consisting of one or two sections, made in the form of a welded structure, consisting of a roof, end walls, side walls, bunkers and resting on undercarriages through the frame. In addition, the hopper car contains automatic couplers and brake equipment. A general view of the hopper car is shown in Fig. one.

The load placed in the body of the hopper car and, in particular, in its cantilever parts, exerts pressure on the metal structures of the car body and frame: vertical effect under the action of gravity and longitudinal effect from inertial forces when starting and braking the car. The transfer of these efforts from the body to the frame, in addition to other nodes, performs each end beam 1 (Fig. 2).

The end beam is shown in Fig. 2, 3. In particular, the end beam 1 comprises an outer vertical wall 2 which bears vertical loads and an upper horizontal flange 4 which bears longitudinal loads. The end beam is installed in the cantilever part of the car, while the outer vertical wall 2 in the middle part of the end beam is adjacent to the mating surface of the socket of the front stop 3, the upper horizontal shelf 4 is located on the upper shelf of the center beam 5. One cantilever is installed on each side of the end beam. bunker 6.

As seen in FIG. 2, 3, the side parts of the end beam are taken out along the longitudinal axis of the hopper car relative to the middle part of the end beam, as a result of which the outer end surfaces of the cantilever bins 6 (see Fig. 2) are taken out of the front stop 3 in the socket area by the value A (Fig. .3). This allows, while maintaining the length and volume of the body, to reduce the length of the hopper car along the axes of coupling of automatic couplers, which increases the linear load of the car.

The outer vertical walls 2 of the side parts of the end beam 1 can be connected to the outer end surfaces of the cantilever bins 6. In cases where there is a gap between the outer vertical wall 2 of the end beam 1 and the outer end surface of the cantilever 6 bin, compensating inserts 7 are installed in the form of a sheet (Fig. 2). Compensation inserts between the end beam and the cantilever hopper are necessary to eliminate the gaps that inevitably form between large nodes. Elimination of gaps without compensating inserts by pressing the cantilever bins to the frame is impossible, as this will lead to a violation of the positioning of the cantilever bins necks. Compensation inserts 7 are made of metal, which ensures their strength properties and resistance to destruction by mechanical loads that are applied to the compensators when they are located between the end beam and cantilever bins.

Cantilever bunkers 6 can be installed on the side parts of the end beam 1 directly or through the longitudinal beams 8.

The value A, by which the outer end surfaces of the cantilever bins 6 are extended beyond the front stop 3, can be from 1 to 400 mm, preferably from 5 to 300 mm.

When A is less than 1 mm, there is no overhang as such. In addition, the minimum size of the offset depends on the tool's ability to determine the offset. If the offset value A exceeds 400 mm, then when the draft gears are compressed (during the collision of cars), the components of adjacent cars may touch. The maximum offset size is determined by the distance from the coupling axis of the automatic couplers to the front stop with fully compressed draft gears of the automatic coupler, and also depends on the width of the cantilever part of the hopper car, the base of the hopper car and the requirements of the overall dimensions. The offset value can be calculated by geometric drawing.
