Abstract

The invention relates to railway transport, in particular, to all metal freight, special-purpose cars for transporting light-weight cargoes.The technical result of the proposed invention is aimed at increasing the car body carrying capacity.The body of an all metal freight car (fig.2) comprises two side 1 and two end 2 walls. The end walls 2 are provided with longitudinal beams 5 for increasing the body carrying capacity, for the same purpose the frame of side walls is provided with lateral longitudinal beams 15, the latter are rigidly fixed on extreme supports 12 and on angular supports 4 at the level of the end longitudinal beams (fig.3). Fastening of each longitudinal beam 15 to the extreme support 12 are strengthened by rectangular cover plates 16.In places of connection side wall strapping 13 and upper end wall strapping 6 (fig.2,5,6) there provided additional triangular-shaped elements 17.

Description

The invention relates to railway transport, namely to all-metal specialized cargo cars, in particular to the bodies of cars for the transport of lightweight goods.

Known body covered specialized car, consisting of two end walls and two side, sheathed outside corrugated sheets (see RF Patent No. 26309 for a utility model, MPK7 B 61Ό 3/16, 2002).

The disadvantage of the body is the low carrying capacity.

The closest set of essential features of the present invention is an all-metal freight car containing two side and two end walls, while the frame of each end wall is made of two middle racks, two corner racks, upper and lower straps, and the frame of each side wall is made of middle and extreme racks, top trim and sheathed outside corrugated sheets (see. Catalog Freight cars of 1520 mm gauge railways. Reference album 002I-97 PKB TsV. Publishing House PKB of the Department of Carriage zyaystva MPS RF, 1998).

The disadvantage of this body is low bearing capacity, due to the fact that the side and end walls have a deflection within the elastic deformation of the wall under the action of the load and in the joints of the upper trim of the end wall with the upper trim of the side wall there is a concentration of stresses in the area of the right angle due to sharp load direction changes.

The technical result when using the present invention is to increase the carrying capacity of the body.

This result is achieved by the fact that the body of an all-metal freight car containing two side and two end walls, while the frame of each end wall is made of two middle racks, two corner racks, upper and lower straps, and the frame of each side wall is made of middle and extreme racks, top trim and sheathed outside corrugated sheets, provided with side longitudinal beams rigidly mounted on the corner posts of the end wall and on the outer stands of the side wall, end longitudinal beams, fixed At the level of the lateral longitudinal beams, additional elements are made at the joints of the upper end and side walls, which form a box section with the top wall, and the bottom wall is made of three parts located at different levels along the height, attached to the frame of the end wall and the frame of the car, and the middle part of the strapping is attached to the end wall and frame of the car.

In addition, additional elements are made of a triangular shape, and the longitudinal beams are installed on the corner posts of the end wall and on the extreme posts of the side wall by means of a rectangular lining.

The invention is illustrated in the drawings.

FIG. 1 shows the car body, general view;

in fig. 2 is a view A of FIG. one;

in fig. 3 is a view B in FIG. one;

in fig. 4 — node I in FIG. one;

in fig. 5 — node II in FIG. 2;

in fig. 6 is a section BB in FIG. five;

in fig. 7 shows the node III in FIG. 2;

in fig. 8 is a section bb of FIG. 7

The body of the cargo all-metal car (Fig. 2) contains two side 1 and two end 2 walls. End walls 2 body contain frame 3 (Fig. 3), made of two middle pillars 3, two corner pillars 4, end longitudinal beams 5 to increase the carrying capacity of the body, upper trim 6 and lower trim, consisting of extreme elements 7, 8 and middle element 9. Inside the body, the frame is sheathed with smooth sheets 10. The side walls 1 of the body contain a frame (FIG. 1) made of vertical middle pillars 11, extreme posts 12 and upper trim 13. The frame is sheathed outside the car with corrugated sheets 14.

To increase the carrying capacity of the body, the frame of the side walls on both sides is provided with side longitudinal beams 15 fixed on the extreme uprights 12 and corner posts 4 at the level of the end longitudinal beams 5 (FIG. 3), and the corrugated sheets 14 are rigidly attached to the longitudinal beams 15. mounting each longitudinal beam 15 to the extreme rack 12 reinforced plates 16 of rectangular shape.

At the junctions of the side wall 13 and the top wall 6 trim (in FIGS. 2, 5, 6), additional elements 17 of a triangular shape are installed, forming a box-section (FIG. 6) with the side wall upper strapping 13 and adjacent to the vertical rack 11 side wall. This prevents the concentration of stresses in the area of the right angle of connection of the upper trim 6 side and end walls and increases the carrying capacity of the specified node.

Extreme elements 7, 8 and the middle element 9 strapping are located at different levels in height. The extreme parts 7, 9 of the strapping are part of the frame of the end wall 2 and are rigidly attached to the frame 18 of the car, and the middle part 9 is attached to the end wall 2 and to the upper surface of the shock outlet 19

- 1 008289 frames 18.

On the lower shelf of the middle part of the strapping 9 (Fig. 7), oblique cuts D are made to increase the length of the weld and reduce the stress concentration in the weld, which increases the strength and carrying capacity of the joint.
