Description

The utility model relates to railway transport and can be used in the construction of a railway gondola car.

There are known designs of railway gondola cars containing two bogies, an auto brake, a parking brake, a frame, two automatic coupler installations, a body with hatch covers installed on the frame and including two side walls and two end walls, which are made in the form of sheets with corrugations arranged horizontally (see Fig. 206 "American Railroad Encyclopedia. Wagons and Wagon Economy", All-Union Publishing and Printing Association of the Ministry of Railways, Moscow, 1961 (1)). Corrugations in this case act as stiffeners for the end walls. The disadvantages of this design include the following:

1) the constant balance of the cargo carried after unloading in the internal cavities of the corrugations;

2) the complexity of the manufacture of end walls due to the need for special die tooling;

3) the impossibility of increasing the rigidity of the end walls without increasing its metal content, because in the design there are no racks and belts as reinforcing elements.

The closest in technical essence and the achieved result to the declared railway gondola are technical solutions for railway gondola cars containing two bogies, an auto brake, a parking brake, a frame, two automatic couplers, a body with hatch covers fixed to the frame and including two side walls and two end walls of die-welded designs that contain the upper harness, the lower harness, corner racks, belts, racks, panels:

1. gondola car model 12-196 manufactured by Uralvagonzavod,

of which two vertical posts are installed on the end walls connecting the lower belt with the lower harness, and in the middle part there is a vertical rack connecting the upper and lower zones (see article by authore K.P. Demin, V.T. Efimov, L.M. Vasilieva, “Development of a new generation of gondola cars with improved technical and economic indicators,” Heavy Engineering magazine, August 8/2005, pp. 14-18 (2)).

2. a railway gondola car of model 12-783 or model 12-757 ei-2 built by the Kryukov Carriage Works concern (see the Gondola car brochure (3)) with an end wall that has an upper belt and a lower belt made of П -shaped profile, and two or three racks made of a U-shaped profile, welded to the bottom, panel and lower belt.

The disadvantages of such designs include:

1) their insufficient strength, requiring reinforcement of the end wall structure (see page 15 (2)), especially under conditions of increased loads.

2) the imperfection of the fastening of the elements of the end wall between them does not provide a rational distribution of loads between the elements.

The utility model solves the problem of improving the design of a railway gondola by strengthening and improving the design of the end walls.

To achieve the specified technical result in a railway gondola containing two bogies, an auto brake, a parking brake, a frame, two automatic couplers, a body with hatch covers installed on the frame and including two side walls and two end walls, each made in the form of welded structures, each of which contains the upper harness, the lower harness, two corner posts, panel, two belts, two racks, the upper belt and the lower belt are made of

 Ω-shaped profile and when welding it to the panel, a closed loop is created for the entire width of the end wall, and each of the racks is made of a U-shaped profile and consists of two parts - the middle rack and the lower rack, which are welded to the upper belt, the ring panel lower, lower strapping, forming a closed profile along the entire length of the mount.

Distinctive features of the proposed railway gondola car from the above-mentioned well-known railway gondola cars are the execution of the upper belt and the lower belt of the Ω-shaped profile and when welding it to the panel, creating a closed loop over the entire width of the end wall, as well as the execution of racks made of П -shaped profile of two parts - the middle and lower racks, which are welded to the upper belt, panel, lower belt, lower harness, forming a closed profile along the entire length of the fastening.

Due to the presence of these signs, the design of the end walls of the railway gondola car is strengthened and improved, as well as the rational distribution of loads between the elements of the end walls during operation of the railway gondola car.

The proposed railway gondola is illustrated by the drawings shown in figures 1-7.

Railway gondola (Fig. 1), containing two bogies 1, auto brake 2, parking brake 3, frame 4, two automatic couplers 5,

the body 6 with the installation of hatches 7 mounted on the frame 4 and including two side walls 8 and two end walls 17 (figure 2, 3), which are made in the form of stamped-welded structures, each of which contains the upper strapping 9, the lower strapping 10, two angular racks 11, panel 12, two belts: the upper belt 13 and the lower belt 14, made of an Ω-shaped profile; two racks, each of which consists of two parts: middle racks 15 and lower racks 16, made of a U-shaped profile.

The upper belt 13 and the lower belt 14 are welded to the panel 12, forming a closed loop 18 (Fig. 4) over the entire width of the end wall 17.

The middle stand 15 and the lower stand 16 are welded:

1) to the upper belt 13, forming a closed loop 19 (Fig.7);

2) to the panel 12, forming a closed loop 20 (Fig.6);

3) to the lower belt 14, forming a closed loop 21 (figure 5).

The operation of a railway gondola car is carried out in this way.

The railway gondola operates as a railway vehicle for the transportation of various bulk industrial goods that do not require protection from the effects of the atmosphere. Gondola loading is carried out in an open way in a body. The weight of the loaded load statically affects all elements of the body, including on the installation of manhole covers on the side walls; transmitted to the frame and through two carts to the railway track.

When a loaded railway gondola car moves, all these loads increase due to dynamic loads, including and to the end wall.

When unloading a railway gondola car through manhole covers or on a tipper car, these loads also increase due to technological loads on body elements at the loading and unloading fronts.

The operation of a railway gondola car during these three operations is to perceive everything without damage, deformation, etc.

load. The loads on the end walls are transmitted through the panels and are perceived by all other elements of the end walls. Strengthening and improving the design of the end walls, and the rational distribution of loads between the elements of the end walls during operation of a railway gondola car, is ensured by the fact that the upper belt and the lower belt are made of an Ω-shaped profile and, when welded to the panel, create a closed loop over the entire width of the end wall and due to the fact that the racks are made of a U-shaped profile and consist of two parts: middle racks and lower racks, which are welded to the upper belt, panel, lower belt, lower trim, ar Zuya closed profile on the whole length of the fixing.
