Description

The utility model relates to the field of railway transport and can be used in cargo gondola cars with unloading hatches.

Known gondola car with unloading hatches, containing a body with unloading hatches in its bottom, unloading hatches are equipped with covers, to hold the covers in the open position on the transverse beams of the body frame, stop brackets are fixed, made in the form of an L-shaped platform, carried by a stiffening rib of a reciprocal form, see RU 169110 U1, B61D 3/00, B61D 7/02, publ. 03/03/2017 (prototype).

The technical problem for this gondola car with unloading hatches is its low operational reliability due to the low rigidity and low strength of the stop brackets supporting the unloading hatch covers in their open position.

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

The specified technical result is achieved by a gondola car with unloading hatches, containing a body with unloading hatches in its bottom, unloading hatches are equipped with covers, to hold the covers in the open position, stop brackets are fixed on the transverse beams of the body frame, made in the form of an L-shaped platform mounted on a stiffener L-shaped, the thrust bracket is reinforced with a spacer connecting the stiffener with the transverse beam of the body frame;

- height h of the thrust bracket, measured along the stiffener, can be made in the range of 290 mm to 310 mm;

- the spacer can be placed between the end edge of the stiffener and the transverse beam of the body frame;

- the spacer can be made in the form of a triangular plate with width a at the base, maintained in the range from 235 mm to 265 mm, and height b, sustained from 170 mm to 200 mm.

The claimed utility model differs from the prototype in that the thrust bracket is reinforced with a spacer connecting the stiffener with the transverse beam of the body frame,

- height h of the thrust bracket, measured along the stiffener, is made in the range of 290 mm to 310 mm;

- the spacer is located between the end edge of the stiffener and the transverse beam of the body frame;

- the spacer is made in the form of a triangular plate with width a at the base, maintained in the range from 235 mm to 265 mm, and height b, sustained from 170 mm to 200 mm.

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 - gondola car with unloading hatches, general view;

- in Fig. 2 - gondola car body, hatch covers are conventionally not shown, bottom view, isometric projection;

- in Fig. 3 - remote element "A" from Fig. 2, isometric view;

- in Fig. 4 - bottom view of the thrust bracket, isometric projection;

- in Fig. 5 is a side view of the thrust bracket, isometric view;

- in Fig. 6 - the same, isometric view;

- in Fig. 7 is a plot of equivalent stresses in the thrust bracket versus its height h.

A gondola car with unloading hatches contains a body 1 (Fig. 1) with unloading hatches 2 (Fig. 2) in its bottom 3, a frame 4. Unloading hatches 2 are equipped with covers 2.1 (Fig. 3, 4). To hold the covers 2.1 in the open position on the transverse beams 4.1 of the frame 4 of the body 1, stop brackets 5 are fixed. 5.1.

The thrust bracket 5 is reinforced with a spacer 5.3 (Fig. 5), which connects the stiffener 5.2 with the transverse beam 4.1 of the frame 4 of the body 1, while the height h of the thrust bracket 5, measured along the stiffener 5.2, is made in the range of 290 mm to 310 mm.

Spacer 5.3 can be placed between the end edge of the stiffener 5.2 and the transverse beam 4.1 frame 4 of the body 1 (Fig. 6).

Spacer 5.3 can be made in the form of a triangular plate with width a at the base, maintained in the range from 235 mm to 265 mm, and height b, sustained in the range from 170 mm to 200 mm.

The proposed gondola car is designed for the transportation of bulk cargo, such as coal. To unload bulk cargo, unloading hatches 2 are used, made in the cantilever parts of the body 1 in its bottom 3. To unload bulk cargo, covers 2.1 are released from the latches (not shown). The released covers 2.1, turning down in their hinges, fall onto the L-shaped platform 5.1 of the stop brackets 5, which limit the angle of rotation of the covers 2.1. Through the resulting gap, the bulk cargo is poured out of the body 1. The rate of spillage of bulk cargo from the body 1 directly depends on the opening angle of the covers 2.1, while the larger the angle of the covers 2.1 open, the greater the height h should have stop brackets 5. With increasing height h of the thrust brackets 5 also increases the bending moment acting on them, arising from the weight of the covers 2.1 and the weight of the bulk cargo, which can lead to bending and breaking of the thrust brackets 5.

To ensure the optimal combination of the speed of pouring out bulk cargo and at the same time maintaining the shape of the thrust brackets 5, the thrust bracket 5 is reinforced with a spacer 5.3 connecting the stiffener 5.2 with the transverse beam 4.1 of the frame 4 of the body 1, while the height h of the thrust bracket 5, measured along the stiffener, made in the range of 290 mm to 310 mm. When the height h of the stop bracket 5 is less than 290 mm, there will be a small opening angle of the covers 2.1 and the spillage of bulk cargo will be slow. When the height h of the thrust bracket 5 is more than 310 mm, the bending moment acting on the thrust bracket 5 increases to the limit values (Fig. 7).

To create a rigid structure, the spacer 5.3 can be placed between the edge of the stiffener 5.2 and the transverse beam 4.1 of the frame 4 of the body 1. In this case, the spacer 5.3 can be made in the form of a triangular plate with a width a at the base, maintained in the range from 235 mm to 265 mm, and height b, sustained in the range from 170 mm to 200 mm. The specified dimensions are determined from the conditions of optimal values and depending on the size of the height h of the thrust bracket 5.

The above means make it possible to increase the rigidity and strength of the thrust brackets 5 supporting the covers 2.1 of the unloading hatches 2 and, ultimately, to increase the operational reliability of a gondola car with unloading hatches.
