The invention relates to railway transport and to the design of a hopper car intended for the transport of bulk cargo.

The purpose of the invention is to increase efficiency by reducing manual labor, improving unloading conditions.

Figure 1 shows the end wall of the hopper car with a safety hatch, general view; Fig. 2 is a front view security hatch; fig.Z - the same, side view; on Fig.4 - node I in Fig.1; on fig.Z - node II in figure 1.

On the vertical (or inclined) wall 1 of the body, at least one hatch is made, which is closed from the inside by a bracket 2, having brackets 3 for hanging on brackets 4 rigidly attached to the outside of the wall I. Projection of the center of the cover plate 2 onto the horizontal plane is offset relative to the projection of the axis of its suspension 5 to the axis of the car, i.e. the rim tends to press against the wall 1, closing the safety hatch. The magnitude of the displacement of the center of the body relative to the axis of the suspension is 5 ra ra timed. In order to ensure reliable hatching, the curved part 6 of the filling rod 7 of the loading hatches 8 is bent into engagement with the bolts 3 of the bolts 2. The upper part of the rod 7 is hinged to the clevis 9, which is rigidly fixed on the axis 10.

The lower part of the rod 7 is fixed in the groove of the plate 11 and has a handle 12 and stops 13.

If there is another safety hatch on the opposite wall of the body, then fixing it in the closed position can be done at the other end of the axle 10. For this, the end portion of the axle has the same shape as the curved part 6 of the boom 7. This will allow it to engage with the bracket 3 of the second cover of the safety hatch and fix the lock in the closed position.

The hopper car works as follows.

During transport, the cover 2 closes the safety hatch due to its own weight. Additionally, the lid 2 can be fixed in this position by the curved part 6

the rod 7 which engages with the clip 3 of the collar 2. The rod 7 at this position is in the lower position and sealed. As a result, it is easy to monitor the safety of the cargo being transported, since the closed position of the loading and safety hatches is indicated by the lower position of the sealing rod 7. The b-part 7 of the rod 7 can be bent out of engagement with the bracket 3, freeing the crankshaft 2. For this, the handle 12 of the rod 7 is moved upwards and fixed in this position with the help of one of the stops 13. When lifting the rod 7 upwards, the handle 12 moves into the slot of the plate 11, and the upper part of the rod carries along the shackle 9, with which it is hinged united.

The stud 9 rotates with the shaft 10 and releases the locking devices of the hatch covers (not shown) that have been fixed until now.

If it is necessary to unload the car, the rod 7 is moved to the upper position. To do this, it must be raised by applying a force to the handle 13 along the rod 8. In this case, the upper curved part 6 leaves the engagement with the cramp 3, making it possible to turn the bolts 2 relative to the axles of the suspension 5. When there is no vacuum in the body, the crankshaft 2 under its own - Hbw weight is pressed against the wall 1, closed the safety hatch. When an air vacuum is formed in the car body, under the influence of atmospheric pressure, the cap 2 turns in the left direction, moving inside the body, allowing access to air through the opened safety hatch. As a result, the pressure in the body is equal to atmospheric. The lid 2 thereafter, under the action of its own weight, returns abruptly to its original position, striking the wall, which has a favorable effect on the process of unloading the hopper car. After completion of unloading the car cover 2 pos. This is located in an inoperative position to the 1J wall, closing the safety hatch and preventing precipitation from entering the body. If necessary, the claws 2 can be additionally fixed by means of the upper curved part 6 of the rod 7. For this, the rod 7 with Po3136451

using the knob 8, it is necessary to lower it to the lower position.
