Description

(54) CARGO HANDLING DEVICE

one

The invention relates to lifting devices equipped with devices for the automatic release of cargo.

A load gripping device is known, comprising a load hook provided with a locking bracket and a detachment mechanism consisting of a system of spring-loaded levers 1,

This device ensures the release of cargo only when the cargo ropes are loosened when the cargo is supported on the surface.

Closest to the invention is a load gripping device, a housing with an in-axis casting unit mounted on it with a rope to a lifting mechanism and a hook mounted on the housing, equipped with a lifting mechanism containing a locking lever with a spring-loaded latch (2},

A disadvantage of this device is that it ensures the separation of cargo only at a certain, predetermined height.

The purpose of the invention is to provide cargo suspension at any set height.

The goal is achieved by the fact that the device is equipped with a ratchet wheel fixed on the axis of the block and freely mounted on

5 the same gear wheel axis with dogs fixed on it, and the body is equipped with a pivotally mounted with the possibility of swinging: a chag with a gear wheel fixed to it, and

The target is spring-loaded with respect to the lever's knob and installed with the ability to interact with the fist-gear through the itit attached to it.

J5 lia drawing shows the device, obtion view.

The device consists of a short circuit of the housing 1, in which a block 2 is mounted on the axis. A hook is rigidly attached to the housing 1

20 3 with a locking lever 4 fixed on the axis 5. A stop 6 is mounted on one of the arms of the lever 4. In the closed position the lever 4 is held by the latch 7, seated on the axis 8,

25 mounted on the housing 1. A roller 9 is mounted on the latch. Parallel to the aiming 7, a swinging lever 10 is mounted on an axis 11 fixed to the housing 1. A roller 12 and a gear-cam 13 are mounted on the lever 10;

on which the spiral spring 14 acts, pressing it against the stop 15 on the lever 10. At the gear knuckle 13, the tooth-free surface has a variable radius, the latch 7 and the lever 10 are interconnected by a spring 16 so that the longitudinal axis of the spring forms an acute angle with the horizontal . the axis of the lever 10. ha of the face axle of the block 2 bolts 17 secured the ratchet wheel 18, in engagement with the teeth of which there are two pawls 19 which are fixed on gear 20, loosely seated on the axle of the block 2. On the body 1 there is a stop 21 the stroke of the latch 7 and the lever 10. The branch 22 of the cargo cable, enveloping the block 2, is stored on the body of the lifting mechanism (not shown), and the branch 23 is fixed on its drum.

Load handling device work as follows.

When a load is seized, a sling or load brackets hangs on hook 3;; which is closed by lever 4. In this case, support 6 acts on roller 12 and rotates lever 10 and - latch 7, which closes lever 4. Fist 13 interlocks with gear wheel 20 .

When the device is lifted, the branch 23 of the cable is wound onto the drum, turn it on. bolts block 2 and wheel 18 clockwise. The dogs 19 let the teeth of the wheel 18 through, resulting in that the gergens 20 remain stationary.

After the device has been lifted and, if necessary, the load is released, the device is lowered. At the same time, the direction of rotation of the block 2 and the wheels 18, is changed. The dogs 19 will enter the rear wheel with the wheel 18 and rotate the gear 20 counterclockwise. The fist-gear 13 coupled to the gear 20, turning through the roller 9, acts on the latch 7, which rotates around the S-axis,

yes the lever 4f as a result of the load is released under the action of its weight,

The lever 4 releases the roller 12 through the stop b, and the lever 10 under the action of the spring 16 rotates around the axis 11. The pinion-gear 13 leaves the engagement with the gear 20 and under the action of the spring 14 rotates to its original position until the stop 15. "Further lowering unloaded device followed by

rotation of block 2, wheels 18 and gears 20, does not affect; other elements of the device.
