Description

The utility model relates to stairs used inside railway cars for the transportation and storage of goods, necessary to provide access for service personnel inside the car body through a hatch during operation and repair, for example, of a tank car, a covered car or a hopper car.

A railway tank is known from the field of technology, having a trolley with wheels, a tank with a hatch and a hinged lid, an external ladder, a platform, a safety inlet valve, an internal ladder, couplers, a rod with an upper device for inserting a special key, a universal drain device, a lower cover with a gasket and a screw on which the pipeline is additionally installed (patent for a utility model “Lateral device for draining petroleum products from railway tanks” RU 92637 U1, IPC B61D 5/00, published 03/27/2010).

The disadvantage of the known solution is the high complexity of installation and dismantling of the internal staircase during the assembly, operation, and repair of a railway tank.

The body of a covered freight car is known from the technical field, containing side walls, a roof, an internal staircase containing guide posts connected to each other by crossbars, the upper ends of the guide posts are made bent to form hooks. Inside the body in its upper part there is a U-shaped bracket, rigidly fixed relative to the body, the guide posts in the lower part are rigidly connected to spacers, which on the other side are rigidly connected to the side wall of the body, the bent upper ends of the guide posts are engaged with the middle section of the U-shaped staples. The U-shaped bracket contains a middle horizontal section and two outer sections, which form an angle of 90° or, possibly, an angle slightly greater than 90° with the middle horizontal section. The main thing is that the shape of the U-shaped bracket allows you to secure it relative to the body at the extreme sections, and on the horizontal section allows you to secure the ladder so that it is not able to move (slide) along this section. The ladder in the upper part on each side is equipped with limiters made in the form of a plate, each limiter is rigidly connected to the corresponding guide post and its bent end, each limiter is located below the middle section of the U-shaped bracket at a distance L from it, while the distance L between the limiter and the middle section of the U-shaped bracket is selected by calculation from the condition of possible movement of the ladder in the vertical direction when the car moves. The U-shaped bracket can be rigidly attached to the roof of the body or to a beam attached to the roof of the body. The spacers can be made in the form of rods with curved ends, through which the spacers are rigidly attached to the guide posts on one side, and to the side wall of the body on the other side. It is advisable to carry out all rigid connections by welding (the most reliable connection of structural elements experiencing dynamic loads). The limiters provide a rigid connection of the bent end of the racks, preventing possible deformation (bending) of the bent ends when exposed to dynamic loads during the movement of the car (patent for utility model “Body of a covered freight car” RU 213460 U1, IPC B61D 3/00, E06C 5/00 publ September 13, 2022).

The disadvantage of the known solution is the complexity of installation and dismantling of an installed internal staircase, which arises due to the need to install and dismantle limiters, each of which is rigidly connected to the corresponding guide post of the internal staircase. Another disadvantage is the high metal consumption of the internal staircase due to the presence of additional parts used when installing the internal staircase.

The body of a railway car for the transportation and storage of goods is known from the field of technology, containing an internal surface, a manhole, including a shell having an internal surface; on the inner surface of the shell of the manhole, brackets are fixed, configured to accommodate the upper ends of the vertical posts of the internal staircase. , in the lower part on the inner surface of the body, brackets are fixed, designed to accommodate the lower ends of the vertical posts of the internal staircase, and containing a vertical platform, a lower horizontal platform and an upper horizontal platform with a hole (patent for a utility model “Railway car body for transportation and cargo storage" RU 219693 U1, IPC B61D 3/00, E06C 5/00, B61D 5/00, B61D 7/00, publ. 08/01/2023). This technical solution was adopted as a prototype.

The disadvantage of the known solution chosen for the prototype is the low reliability of fastening the internal ladder, since there is a possibility of the internal ladder jumping out of the brackets attached to the inner surface of the manhole shell when vibrations occur during the movement of the railway car.

The technical problem is the trouble-free operation of an internal staircase that does not have the above disadvantages.

The technical result is increased reliability of fastening the internal ladder in the body of a railway car by eliminating the spontaneous jumping out of the internal ladder from the brackets fixed to the inner surface of the manhole shell.

The technical result is achieved by the fact that the body of a railway car for the transportation and storage of goods contains an internal surface, a manhole, including a shell having an inner surface, containing an internal ladder with vertical posts connected by crossbars; brackets are attached to the inner surface of the manhole shell. , in which the upper ends of the vertical posts are located, the upper ends of the vertical posts are made with a bend, and the vertical distance from the manhole cover in the closed position to the uppermost part of the vertical post is less than the vertical distance from the end of the bent part of the vertical post to the upper part of the manhole bracket.

In the body of a railway car for transportation and storage of goods, brackets can be attached to the inner surface in the lower part of the body.

In the body of a railway car for the transportation and storage of goods, the crossbars can be made in the form of broken lines with bends, the shape of which is close to the shape of the bend of the inner surface of the manhole shell.

In the body of a railway car for the transportation and storage of goods, the crossbars can be made with bends, the shape of which is close to the shape of the bend of the inner surface of the manhole shell.

1. the body of a railway car for the transportation and storage of goods, containing,

2. inner surface,

3. manhole, including a shell,

4. having an internal surface,

5. internal staircase with vertical posts,

6. interconnected crossbars,

7. brackets are fixed on the inner surface of the manhole shell,

8. in which the upper ends of the vertical posts are located,

9. The upper ends of the vertical posts are made with a bend,

10. In this case, the vertical distance from the manhole cover in the closed position to the uppermost part of the vertical post is less than the vertical distance from the end of the bent part of the vertical post to the top of the manhole bracket.

Features 1-8 are restrictive features, and features 9-10 are distinctive features of the utility model.

The design of the utility model is illustrated by figures, where in FIG. Figure 1 shows a general view of the internal surface of the body of a railway car for the transportation and storage of goods.

In fig. Figure 2 shows a view of the location of the ladder in the manhole brackets (view A).

The body 1 of a railway car for the transportation and storage of goods (Fig. 1) contains an internal surface 2 and a manhole 3. The manhole 3 includes a shell 4 having an inner surface 5 and a cover 6. The body 1 of a railway car for the transportation and storage of goods also contains an internal staircase 7 with vertical posts 8, which are interconnected by crossbars 9.

The upper ends 10 of the vertical posts 8 are made with a bend and are placed in brackets 11, mounted on the inner surface 5 of the shell 4 of the manhole 3 (Fig. 2), while the distance h from the cover 6 of the manhole 3 in the closed position to the uppermost part 14 of the vertical post 8 is made less than the vertical distance H from the end of the bent part 15 of the vertical post 8 to the top of the bracket 11 of the manhole 3, that is, h<H. The functioning of the internal staircase 7 will be ensured if the inequality h<H is observed in relation to at least one vertical post 8 of the internal staircase 7.

Subject to the inequality h<H, the closed cover 6 of the manhole 3 limits the movement of the vertical posts 8, which ensures that the upper ends 10 of the vertical posts 8 of the internal staircase 7, made with a bend, do not fall out of the brackets 11 placed on the inner surface 2 of the shell 4 of the hatch - manhole 3 of a railway car for transportation and storage of goods 1 (Fig. 2).

In the body 1 of a railway car for the transportation and storage of goods, it can be provided that brackets 12 are fixed on the inner surface 2 in the lower part of the body 1, designed to accommodate the lower ends 13 of vertical posts 8. The presence of brackets 12 allows the lower ends to be fixed in them 13 vertical posts 8 internal stairs 7.

One of the most technologically advanced designs of the body 1 of a railway car for the transportation and storage of goods, which is confirmed experimentally, is the execution of the crossbar 9 in the form of broken lines with bends, the shape of which is close to the shape of the bend of the inner surface 5 of the shell 4 of the manhole 3.
