Description

The utility model relates to the field of railway transport, namely to the design of the center beam of a cargo gondola car with unloading hatches in the bottom of the body.

Known cargo gondola car with unloading hatches with covers in the bottom of the body, mounted on a frame containing a spinal beam, made in the form of a rigidly interconnected lower beam and upper beam, the upper beam is recruited from the upper horizontal shelf, as part of the bottom, and from vertical longitudinal ribs , fixed on the lower beam and carrying the upper horizontal shelf (RU 175343, (Fig. 3), B61D 3/00, B61F 1/02, publ. 12/01/2017 (prototype)).

The technical problem characteristic of this gondola car is its low reliability, due to the low rigidity of the elements of the main beam, namely, the cantilevered side edges of the upper horizontal shelf, which are subjected to vertical action from the bulk cargo carried in the body, which leads to their bending down and increase when gaps between the covers of the unloading hatches and the indicated side edges, leading to the loss of bulk cargo carried in the body.

The technical result of the claimed utility model is to increase the operational reliability of a cargo gondola car with unloading hatches in the bottom of the body.

The specified technical result is achieved by a freight car with unloading hatches in the bottom of the body, mounted on a frame containing a center beam made in the form of a lower beam and an upper beam rigidly connected to each other, the upper beam is assembled from the upper horizontal shelf interconnected as part of the bottom, and of the vertical longitudinal ribs fixed on the lower beam and carrying the upper horizontal flange, the ratio of the distance L between the vertical longitudinal ribs to the width S of the upper horizontal flange is maintained from 0.5 to 0.9, an additional vertical longitudinal rib can be fixed between the vertical longitudinal ribs.

The claimed utility model differs from the prototype in that the ratio of the distance L between the vertical longitudinal ribs to the width S of the upper horizontal shelf is maintained from 0.5 to 0.9, an additional vertical longitudinal rib is fixed between the vertical longitudinal ribs. Such differences give grounds to assert that the proposed technical solution complies with the criterion of patentability of a utility model - "novelty".

The utility model is shown in the drawings, where

in fig. 1 - cargo gondola car with unloading hatches in the bottom of the body, general view;

in fig. 2, 3 - center sill in cross section, with different L/S ratios;

in fig. 4 - spinal in cross section, an additional vertical longitudinal rib is fixed between the vertical longitudinal ribs.

Cargo gondola car 1 (Fig. 1) contains a body 2 with covers 3 unloading hatches in the bottom of the body 2. Body 2 is mounted on a frame 4. Frame 4 contains a center beam 5, made in the form of a lower beam 5.1 and an upper beam 5.2 rigidly connected to each other. The upper beam 5.2 is assembled from interconnected upper horizontal shelf 5.3, as part of the bottom of the body 2, and from vertical longitudinal ribs 5.4, fixed on the lower beam 5.1 and carrying the upper horizontal shelf 5.3.

The covers 3 of the unloading hatches are fixed on the lower beam 5.1 of the main beam 5 by means of bearing brackets 3.1 (Fig. 2).

The upper horizontal shelf 5.3 of the upper beam 5.2 of the main beam 5 is made with a width S. The vertical longitudinal ribs 5.4 of the upper beam 5.2 are fixed at a mutual distance L (Fig. 2, 3). The ratio of the distance L between the vertical longitudinal ribs 5.4 to the width S of the upper horizontal shelf 5.3 is maintained in the range from 0.5 to 0.9.

Between the vertical longitudinal ribs 5.4 of the upper beam 5.2 of the main beam 5, an additional vertical longitudinal rib 5.5 can be fixed (Fig. 4), for example, in the central plane of symmetry of the main beam 5.

The technical result, which consists in increasing the operational reliability of a cargo gondola car with unloading hatches in the bottom of the body, is achieved as follows.

The side parts and side edges of the upper horizontal shelf 5.3 of the upper beam 5.2 of the spinal beam 5 are subjected to significant vertical dynamic and static effects from the cargo placed in the body 2. With a large cantilever overhang of the side edges of the upper horizontal shelf 5.3, such an impact can lead to their downward bending and the creation of increased gaps between the covers 3 of the unloading hatches and the side edges of the upper horizontal shelf 5.3.

To increase the strength and rigidity of the side parts and side edges of the upper horizontal shelf 5.3, vertical longitudinal ribs 5.4 are fixed on the lower beam 5.1 at a mutual distance L, maintained in relation to the width S of the upper horizontal shelf 5.3 in the range from 0.5 to 0.9. If the L/S ratio is less than 0.5, the necessary strength and rigidity of the side parts of the upper horizontal shelf 5.3 will not be provided due to the large cantilever overhang of the side edges of the upper horizontal shelf 5.3, which will lead to a decrease in the operational reliability of the freight gondola car. The implementation of the L / S ratio of more than 0.9 does not provide the possibility of placing on the lower beam 5.1 of the bearing brackets 3.1 covers 3 unloading hatches in the bottom of the body 2, and also creates conditions for the deflection of the upper horizontal shelf 5.3 under the action of a load or under the influence of unloading devices, such as a bucket grab, which also reduces the operational reliability of the freight gondola car.

Installing between the vertical longitudinal ribs 5.4 additional vertical longitudinal rib 5.5, for example, in the central plane of symmetry of the main beam 5, further increases the strength and rigidity of the main beam 5, which increases the operational reliability of the cargo gondola car.

Thus, an increase in the operational reliability of the cargo gondola car 1 with unloading hatches in the bottom of the body is ensured.
