Description

one

The invention relates to a rolling stock of railway transport, in particular to locking devices of manhole covers of a railway gondola car.

The locking device of the hatch cover of a railway gondola car is known, which contains a bracket, hinged by means of rollers to the bottom panel of the side wall of the gondola car, a gauge and a sector interacting with it and a rotary lock 1.

The disadvantage of this device is that under operating conditions during shunting operations and unloading cars using the car dumpers, a sector under the action of inertial forces and vibrations can unlock the jumper, after which the dropout leaves the engagement with the bracket, which can lead to loss of cargo and emergency situation m

The purpose of the invention is to increase the operational reliability of the locking device.

For this, the rotary lock is mounted on the sector roller, and a figure hole for the lock is made in the refill.

FIG. 1 shows a device assembled with no connection of a lock with a sector in the locked position; in fig. 2 - the same, in non-working position; in fig. 3 - view of the device in

plan; in fig. 4 is a section A-A of FIG. one; in fig. 5 shows the device, a variant with a rigid connection of the lock with the sector in the locked position; in fig. 6 - the same

in a non-working position; in fig. 7 is a section BB of FIG. five.

The locking device mounted on the lower side square 1 of the side wall of the gondola body, interacting with the brackets 2 of the hatch cover 3, includes a zakidku 4, a sector 5, a bracket 6 and a rotary lock 7.

The latch 7, made of structural steel, having a large trie

strength good properties, one end fixed together with sector 5 on the roller 8, and the other curved, interacts with the refusal 4, in which the figured hole 9 is made. Clamp 7

can rotate on the roller 8 independently of sector 5 (see fig. 1, 2) or only together with sector 5 (see fig. 6, 5).

In the open position, the rotary lock 7 together with sector 5 freely

hangs on the roller 8. When the hatch cover 3 is closed, the curved end of the retainer 7 is pushed onto the outside plane of the catch 4 by means of a crowbar so that the curved end of the retainer 7 knocks into the hole 9 due to its uirugi properties and thus locks the catch 4 in the closed position . Then, sector 5 is rotated to the working position, which increases the reliability of closing the system.

If it is necessary to unlock the refit 4, the sector 5 is moved to the inoperative position, then the crowbar is inserted between the outer plane of the reflow 4 and the retainer 7 and, overcoming its elastic resistance, the curved end of the retainer 7 is pulled out of the orifice 9 and then beyond the deflection plane 4.

In the case of a locking device with a locking device rigidly connected with the sector, the fixation of the refusal 4 occurs simultaneously with the rotation of the sector 5 to the working position.

The use of the proposed locking device will increase the reliability of locking manhole covers gondola.

The estimated economic effect of the annual production of cars will be 1.5 million.
