Abstract

The locking device of the gondola hatch can be used as a device for locking the hatch covers of freight gondola cars, it contains a hook hook (2) for gripping the supporting bracket (3) fixed on the hatch cover (1) with its teeth (2.1, 2.2). To fix the hook hook (2), an eccentric sector-stopper (4) was used. The reinforcing stiffener (3.2) and the flat reinforcing supporting tides (3.3) are made on the upper surface (3.1), which increases the cross-sectional area of the bearing bracket (3), increasing its strength and stiffness, 2 cp, ft , 3 ill.

Description

The inventive utility model relates to railway transport and can be used as a device for locking the closed hatch covers of open wagons.

Known locking device of the hatch of a gondola car, containing a hook-hook pivotally mounted on the lower harness of the gondola car body, serving to grip a supporting bracket mounted with a tooth on the gondola hatch, and an eccentric sector stopper used to fix the hook-hook in the working position USSR certificate No. 184925, B61D 7/16, publ. 30.07.1966.

The disadvantage of this locking device is the non-rigid design of the bearing bracket, leading to its possible bending and kink during operation of the gondola car, due to the undeveloped cross section of the bearing bracket.

A locking device for a gondola car’s hatch is also known, comprising a hook-hook pivotally mounted on the lower harness of the gondola car body, which serves to grip the carrier arm fixed to the gondola car’s hatch, and an eccentric sector stopper used to fix the hook-hook in the working position, USSR copyright certificate No. 1219438, B61D 7/16, publ. 03/23/1986 (prototype).

This device has a similar drawback - the non-rigid design of the bearing bracket, leading to its bending and possible fracture during operation of the gondola, due to the undeveloped cross-section of the bearing bracket.

The technical result of the claimed utility model is to increase the reliability of the locking device of the hatch of a gondola car by increasing the strength and stiffness of the supporting bracket

The claimed technical result is achieved by the fact that the locking device of the hatch of the gondola car containing pivotally mounted on the lower harness of the gondola car body has a hook-up made with the possibility of grabbing with its own tooth a support bracket mounted on the hatch of the gondola car, and an eccentric sector-stopper made with the possibility of fixing in the working position of the hook hook, reinforcing stiffener is made on the upper surface of the supporting bracket; flat reinforcing supporting tides can be made on the upper surface of the supporting bracket; the hook hook can be equipped with an additional tooth used for pre-grabbing the supporting bracket.

Comparative analysis with the prototype shows that the locking device of the hatch of a gondola car differs from the prototype in that in order to increase the stiffness and strength of the supporting bracket, a reinforcing stiffener is made on its upper surface; flat reinforcing supporting flushes are made on the upper surface of the supporting bracket, the hook hook is equipped with an additional tooth used for preliminary gripping of the supporting bracket. This difference from the prototype gives reason to argue that the proposed technical solution meets the patentability criterion of a utility model - "novelty."

The inventive utility model is illustrated by drawings: where in FIG. 1 shows a drawing of a locking device for a gondola hatch, main view; in FIG. 2 is a plan view of FIG. one; in FIG. 3 is a General view of the locking device of the hatch of a gondola car, isometric view.

The locking device of the cover 1 of the gondola car hatch (Fig. 1, 2, 3) contains a hook hook 2 for grasping with its teeth 2.1 or 2.2 of the support bracket 3. The support bracket 3 is mounted on the cover 1 of the gondola car hatch. For fixing in the working position of the hook-hook 2, the eccentric sector-stopper 4 is used. The hook-hook 2 and the eccentric sector-stopper 4 are pivotally mounted on the lower trim 5 of the gondola car body. To increase the strength and stiffness of the bearing bracket 3 on the upper surface 3.1 of the bearing bracket 3, reinforcing stiffener 3.2 is made. On the upper surface 3.1 of the supporting bracket 3, flat reinforcing supporting tides 3.3 can be made.

The locking device of the hatch of a gondola car is used as follows.

When closing the cover 1 of the gondola car’s hatch, hook-hook 2 with tooth 2.1, if necessary, engage in preliminary engagement with the bearing bracket 3. After the final closure of the cover 1 of the gondola car’s hatch, hook-hook 2 with tooth 2.2 is put into final engagement with the bearing bracket 3, locking the cover of 1 hatch gondola car. Then, the eccentric sector-stopper 4 is rotated on the axis 4.1, reliably locking the gondola hatch cover 1 and the hook hook 2 on the support bracket 3 when closed. Performing reinforcing stiffeners 3.2 on the upper surface 3.1 of the support arm 3 increases the cross-sectional area of the support arm 3, what increases its strength and rigidity, eliminates its unwanted bending and possible breakdown during operation of the gondola car. Flat reinforcing supporting tides, 3.3, made on the upper surface 3.1 of the bearing bracket 3, serve to protect the upper surface 3.1 and also increase the strength and stiffness of the bearing bracket 3 by further increasing its cross-sectional area, which also improves the reliability of the locking device of the gondola car hatch .
