SU914371A1 - Locking device for open car hatch cover - Google Patents

Description

The invention relates to railway transport, namely, devices for locking the hatch cover of a gondola car.

A locking device of a gondola door hatch is known; it contains articulated hinges on the bottom trim of the side wall of the body by means of a shackle and rollers, a zakidka and a clamp with a longitudinal groove for the roller, placed between the lower trim and the clamp plate spring Ш.

The disadvantage of this locking device is its low operational reliability, since the ingress of dust and dirt between the leaf spring and the latch will lead to loss of efficiency.

The purpose of the invention is to improve the reliability of the locking device in operation.

This goal is achieved by the fact that the device is equipped mounted in the bracket with the possibility of re 2

Placement in a plane perpendicular to the plane of the retainer with a locking frame made with a longitudinal groove and with restrictive protrusions for interacting with the bracket, and fix ⁵ is made with tide on the working surface for interacting with the locking frame.

FIG. 1 depicts a locking

• device in closed position, general view; Fig 2 is the same, top view; Fig, 3 ~ locking device in the open position, a general view.

The proposed mechanism consists of a refusal 1, hinged in the bracket 2, mounted on the bottom harness 3 body. Zakidka 1 in the closed position is installed under the bracket 4 of the hatch 5. In the bracket 2 on the axis 6

„The hinge 7 with pro Λ is hinged. _ about

downstream groove A, tide B and handle

B. Lock 7 tide B is

in contact with the reflash 1, the ends with the handle are placed in the guide 8. Between

the inner surface of the tide B and the guide 8 is placed a locking frame 9 "retaining zakidku in the" Closed "position, the locking frame is provided with restrictive movement lugs: upper G and lower D.

The internal size of the locking frame is made taking into account the possible maximum displacement of the hatch cover bracket. To allow the latch to pass to the “Open” position, a longitudinal groove E is provided in the locking frame. The length of the longitudinal groove A in the latch takes into account the possibility of installing it according to the actual position of the reflux in both the open and e-closed positions.

Between the lower body trim 3 and the latch 7 on the same axis 6 with the latch is placed the leaf spring 10, one end inserted into the guide 8. The spring 10 keeps the locking frame 9 and the latch 7 in the clamp in the bracket, thereby preventing the mechanism from unlocking on the gondola wagon tipper and in the process of movement. '

The installation mechanism for closing is as follows.

The latch 7 is installed tide B in the stop with zakidku 1, the locking frame 9 rests one side against the inner surface of the tide B, guide 8, which is then welded to the bottom trim of the body, closely adjoins the opposite side of the frame.

The opening mechanism occurs in the following order.

The locking frame 9 lifting up the upper limit protrusion 7 is brought out of contact with the tide B of the lock 7 ° and the guide 8 all the way down the bottom projection D into the bracket 2. In this position, the groove E is located

above the edge of the tide retainer and it gets the opportunity to move the longitudinal groove of the retainer and the guide, freeing the refusal.

The friction forces that occur between the bracket, the latch and the locking frame, caused by the action of the leaf spring, exclude the possibility of spontaneous movement of the parts of the mechanism in any position.

The economic effect of the introduction of the present invention is to improve the reliability of the locking device in operation by preventing the possibility of its opening in operation, when unloading a gondola car wagon tipper.

Claims (1)

Claim A locking device for the hatch of the gondola hatch, which is hinged on the lower trim of the side wall of the body by means of a clip and rollers, and a lock with a longitudinal groove for the roller, placed between the lower trim and the lock plate spring, characterized in that, to increase operational reliability, it fitted with a bracket mounted for movement in a plane perpendicular to the plane of the retainer, with a locking frame made with a longitudinal groove and with restrictive protrusions for interlocking mode with the bracket, and the latch is made with a tide on the working surface to interact with the retaining frame.
