Description

The utility model relates to the structure of a freight car body, namely to the design of an internal staircase in the body of a gondola car.

A gondola car body is known, containing side and end walls; in the body, on the inner sides of the end walls, steps of the internal staircase are installed, see RU 177170, B61D 17/06, B61D 23/00, publ. 02/12/2018 (prototype).

The technical problem of this gondola car body is its low reliability, caused by the protrusion of the internal staircase steps beyond the inner surface of the end wall skin, which for this reason are exposed to the influence of the cargo transported in the gondola car body.

The technical result of the utility model is to increase the reliability of the gondola car body.

The specified technical result is achieved by a gondola car body containing side and end walls, in the body, on the inner sides of the end walls, steps of the internal staircase are installed, each of the steps of the internal staircase is installed in a protective horizontally elongated niche-recess made in the lining of the end walls;

the niche-recess can be made in the form of a stamped elongated cap with support flanges, secured in matching slot holes made in the cladding of the end walls;

the step can be made of a rod fixed at its ends in a niche-recess;

the step can be made from a corner fixed with its shelf on the surface of a niche-recess.

The utility model differs from the prototype in that each of the steps of the internal staircase is installed in a protective horizontally elongated niche-recess made in the cladding of the end walls;

the niche-recess is made in the form of a stamped elongated cap with support flanges, fixed in matching slot holes made in the cladding of the end walls;

the step is made of a rod, fixed at its ends in a niche-recess;

the step is made of a corner fixed with its shelf on the surface of a niche-recess.

Such differences give grounds to assert that the proposed technical solution meets the criterion of patentability of a utility model – “novelty”.

The utility model is presented in the drawings, where:

in fig. 1 – gondola car body, cross section, isometric view;

in fig. 2 – extension element “A” from Fig. 1, the step is made of rod;

in fig. 3 – extension element “A” from Fig. 1, the step is made from a corner.

The body 1 (Fig. 1) of the gondola car contains side walls 2, end walls 3. In the body 1, steps of the internal staircase 4 are installed on the inner sides of the end walls 3.

Each of the steps of the internal staircase 4 is installed in a protective horizontally elongated niche-recess 5 (Fig. 2, 3), installed in the casing 3.1 of the end wall 3.

The niche-recess 5 can be made in the form of a stamped elongated cap 5.1 with support shoulders 5.2. The elongated cap 5.1 is fixed in matching openings-grooves (not shown) made in the casing 3.1 of the end walls 3.

The step can be made of a rod 6, fixed at its ends in a niche-recess 5.

The step can be made from a corner 7, fixed with its shelf on the surface of the niche-recess 5.

When loading and unloading, transporting goods in body 1, the side walls 2, end walls 3, as well as the 3 steps of the internal staircase 4 located inside the body 1 on the end walls are subject to mechanical, impact effects from cargo elements, loading and unloading mechanisms, leading to breakage of the steps and the brackets holding them. To prevent the destruction of the steps of the internal staircase from such an impact in the proposed design of the body 1 of the gondola car, the steps of the internal staircase 4 are installed in a protective horizontally elongated niche-recess 5, made in the skin 3.1 of the end walls 3. The placement of the steps of the internal staircase 4 in the indicated protective niches-recesses 5 leads to steps from vertical force, for example, from bulk cargo falling from above, the impact of elements of loading and unloading mechanisms, keeping the steps of the internal staircase in working condition.
