Description

The proposed utility model relates to railway transport, and in particular to gondola car body structures.

Known designs of end walls [1, p.46-53.61] of bodies of universal gondola cars of model 12-119, gondola cars with a deaf body of model 12-1592, gondola cars for technological chips of model 12-4004, copper ore model 12-4024, cars for bulk metallurgical cargo (model 22-4008).

The end walls of the listed gondola cars are flat in shape and include upper and lower trim, two side profiles, two horizontal stiffening belts and a flat sheathing made of sheet steel. The lower stiffness belt is connected with the end beam of the body frame with three (model 12-1592) or two (model 12-119) short struts (half-racks). Harnesses and horizontal stiffeners have a rectilinear shape.

Known designs of flat end walls of gondola car bodies have the following disadvantages:

in trains made up of gondola cars with flat end walls, no intercar space is used to accommodate cargo, as a result of which the gondola car body has an increased frame length to obtain the required loading volume, which leads to an increase in the length of the train;

- the upper harness and horizontal stiffness belts of the end wall are subject to significant lateral bending from the effect of the pressure of bulk or lumpy cargo on them.

The purpose of the proposed utility model is to increase the loading volume of the gondola car body without increasing its length along the frame.

The objective of the utility model is the development of the end wall of the gondola car body, which allows the use of intercar space to accommodate the transported cargo.

An end wall of a gondola car body is proposed, including a carcass of two lateral straight profiles, horizontal curvilinear stiffening belts and vertical half-racks, covered by sheathing sheets and a bottom of sheets and inclined half-racks, connected to the end beam of the body frame, characterized in that it is made of a cylindrical or prismatic shape bulge towards the head of the automatic coupler, and the bottom hangs over the body of the automatic coupler.

The proposed design of the end wall of the gondola car body allows you to: increase the loading volume of the gondola car without increasing the length of the body along the frame; increase the actual carrying capacity of a gondola car; to form railway trains of the same mass from a smaller number of gondola cars; reduce the level of stresses causing lateral bending of the belts, reinforcing the wall sheathing.

To clarify the described object, the figures show the construction of the end wall of the gondola car body. Figure 1 shows a front view of the end wall. Figure 2 shows a view of the wall on the left, figure 3 is a view of the wall from above with a cylindrical shape of the wall. Figure 4 shows a top view with a prismatic shape of the wall, figure 5 is a section aa (figure 1).

The proposed object is as follows. The end wall includes: an upper horizontal belt 1 made of a pipe of rectangular cross section; two intermediate horizontal belts 2 from a bent profile in the form of a channel; the lower curved belt 3 of a special bent profile (figure 5), which connects the vertical part of the end wall and the inclined bottom. Horizontal and curved belts at the ends are welded to the corner profiles 4, made in the form of a corner bent at an obtuse angle. Three half-racks from a bent channel are welded between the lower intermediate and curvilinear belts: left 5, middle 6 and right 7. Under the curvilinear belt 3 there are inclined half-racks 8, 9 and 10 of the bottom 13, which are welded with the upper end to the curved belt and the lower to the end beam body 14 (figure 5). At the junctions of the half-racks to the curved belt, the connecting stampings 15 are welded into it (Fig. 5). The resulting frame is overlapped with sheathing sheets: upper rectangular 11, lower 12 with one curved edge. To the lower curved belt 3, a sheet 13 and a half-rack 8, 9, 10 of the bottom are welded (Fig. 5).

The corner posts 4 of the end wall are connected to the corner profiles of the side walls of the gondola car. The flange bottom sheet 13 is connected to the horizontal shelf of the end beam 14 of the body frame. The connection diagram is shown in figure 5.

The dimensions of the walls a and b (Fig. 2) are selected from the condition of the contact of two adjacent cars with full compression of the coupler and the contact of two neighboring cars in the area of the upper strands of the end walls when passing the coupling of the ramp.

Thus, the proposed design of the end wall of the gondola allows you to: increase the loading volume of the car without increasing the length of the body along the frame; reduce the length of the train in comparison with the composition of the same mass formed from gondola cars of the existing structure; increase the actual carrying capacity of a gondola car.
