SU878631A1 - Mechanism for locking train car hatch cap - Google Patents

Description

one

The invention relates to rail transport and can be used for locking manhole covers in the roofs of covered wagons.

A known mechanism is to lock the hatch of a railroad car hatch, preferably a loading hatch, containing a refit with an L-shaped tooth, hinged to the body by means of a clevis and interacting with a bracket rigidly attached to the hatch cover, and the lock refit 1.

However, such a locking mechanism opens from the outside of the car.

The purpose of the invention is to increase reliability by preventing the possibility of opening the hatch cover from the outside of the carriage.

For this purpose, the retainer is made in the form of a cylindrical rod, a vertical groove for the retainer is made in the bracket, and the L-shaped tooth of the zakidka is located above the hinge, with the length of the horizontal tooth flange more than the distance from the retainer contact point to the bracket .

FIG. 1 shows the locking mechanism, the cut; in fig. 2 - the same, when closing the hatch cover.

A brace 2 is rigidly fixed on the lid of the cargo compartment lid of the freight car. The ball is equipped with two double-shouldered jumpers 3. On one shoulder of the jumper there are 5 handle 4, under the force of gravity of which the jumper turns to fit 5 on the bracket and serving to hold the refill in the ready-for-action position, the other ple10 but has an L-shaped tooth 7. On the lid 8 of the hatch, the bracket 9 is rigidly fixed, having a jumper 10 and grooves A, in which a LIP 11 is installed. ghee and

15, the dust cover has a rubber seal 12, which is attached to the casing 1 and, in the closed position of the hatch, fits snugly to the cover. The length of the horizontal tooth flange is longer than the distance from the point of contact of the fixture with the gauge to the bracket.

The hatch on the outside of the car is closed by pressing the cover 8. When the hatch is closed, the reflux tooth 3 slides over the bridge 10 and simultaneously lifts the latch AND installed in the grooves A of the bracket 9. At the same time, the hinge rotates around the axle. the handles 4 are rotated and the refill tooth enters

30 for the jumper 10. Latch And at the same time, it moves by gravity to the lower position and locks the refusal.

To open the hatch, it is necessary to raise the latch 11 and, holding it in the upper position, turn the reflash 3 by the handle 4. The reflux tooth 7 is disengaged from the jumper 10, and the rubber seal presses the lid 8 upwards. After that, the cover is swung back from the inside of the car and the hatch opens.

The use of the proposed device will eliminate the opening of the hatch cover from the outside and thereby increase the safety of the transported goods.
