Description

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

Hopper cars are self-unloading bunker freight cars. Hoppers have a body with inclined end walls for unloading cargo by gravity and unloading bins with hatches that open when unloading.

During unloading, sticking of the load may occur due to, for example, its ability to caking. In this case, to facilitate the precipitation of the load, vibrators are used that are installed on the hopper using special devices for setting the vibrators and transmitting alternating loads, providing deagglomeration of the cargo and its unloading. Such a device may be a base plate mounted on the outer walls of the hoppers.

Four-axle railway hopper cars of the models 19-752, 19-758, 19-923, 19-953, 19-969 are known.

As the closest analogue for this utility model, the decision was made, disclosed in document KZ 856 U, IPC B61D 7/02, December 6, 2011 “Covered hopper for grain transportation”. According to this document, the hopper car contains a frame, a body, six hoppers, three on each side of the body. To facilitate the precipitation of the load, devices for setting vibrators are provided.

Vibrator mounting devices used in known hoppers are thrust plates having a substantially rectangular shape, which leads to their relatively high mass, low fastening reliability due to the small length of the welds and low reliability of the body due to the increased level of stresses at the points of fastening of the plate to the sheet bunker.

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

This utility model relates to a hopper car containing a body mounted on running bogies with two or three rows of hoppers in the inter-car space, couplers and braking equipment, and there are vibrator plates on the hoppers, characterized in that there are on the sides of said plates notches.

Each plate is hourglass-shaped, 410 mm long, 380 mm wide and 8 mm thick.

The recesses have a radius of 170 mm.

The recesses are indented from the upper and lower edges of the slab 80 mm.

The plate has a thickness of 8 mm, in contrast to analogues with a thickness of 10 mm, which reduces the metal consumption and the weight of the car.

The plate is attached to the hopper by welding.

Plate material 09G2S, strength class not lower than 325 MPa, plate weight 12 kg.

The technical problem is to provide improved operational characteristics of such a car, namely: reduced tare mass, increased reliability of fastening the plate to the hopper and increased reliability of the body by reducing stresses in the places of fastening the plate to the sheet of the hopper.

The technical result is to increase the reliability of fastening the plate to the bunker of the car.

The essence of the utility model is illustrated by the images:

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

FIG. 2 - hopper of a four-axle hopper car with a plate for a vibrator according to this utility model;

FIG. 3 is a general view of the slab according to the present utility model.

The four-axle hopper car (Fig. 1) contains a pair of bogies and two or three transverse rows of bins in the inter-body space, each of which has a device for a vibrator to facilitate unloading of the product. Such a device is a plate attached to the wall of the hopper, having stops that fix the position of the vibrator.

For unloading the wagon, a vibrator, for example, a pneumatic one, is installed on the plate to transfer alternating loads to the hopper wall to accelerate the rash of the load.

These loads lead to fatigue stresses in the places of fastening the plate to the wall, which leads to the disconnection of the plate, and the need for repair activities of the car.

To strengthen the seam, as a rule, welded, it is proposed to make a plate in the form of an hourglass, extending the length of the side wall, and, accordingly, the surface to be welded.

The figure 2 presents a view of the lower part of the hopper 1 four-axle hopper car, on the wall of which is attached a plate 2 under the vibrator.

Plate 2 has a generally hourglass shape due to recesses on the sides of the plate 2.

Figure 3 shows a more detailed view of the shape of the plate 2.

The length of the plate is 410 mm, width 380 mm, thickness 8 mm.

Each recess has a radius of 170 mm with a spacing of 80 mm from the upper and lower edges of the plate.

This design provides an extension of the mounting joints, in particular, the welds of the plate, which favorably affects the reliability of fixing the plate to the wall of the hopper.

In addition to the fact that the recesses provide hardening of the mounting seam, they also play the role of lightening holes.

This reduces the weight of the car due to the reduction in weight of each plate to 5.5 kg, given that each car contains from 4 to 6 plates.

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