Description

(54) CARGO HANDLING DEVICE

one

The invention relates to a lifting and transport equipment, namely to lifting devices, and can be used in loading and unloading operations using containers.

A load gripping device is known, comprising a traverse with cargo rods attached to it with hooks, unloading rods connected to a cable wound on a drum with a return spring installed inside it, and a locking mechanism in the form of two shoulders attached to the traverse body. locking and locking levers 1.

The disadvantages of this device are the manual slinging and slashing of the double-leaf container, as well as the lack of automatic opening of the box at a given height.

It is also known lifting device containing the traverse, rotary gripping levers, the mechanism for fixing the levers in the open position with a rotary locking lever that interacts with the abutment attached to one of the gripping levers, and a block with a rope lifting mechanism 2.

However, this device does not provide container disclosure at any given

height.

The purpose of the invention is to improve ease of operation by ensuring containers are opened at any given height.

ten

The goal is achieved by the fact that the device is equipped with spring-loaded cargo levers pivotally attached to the traverse, pivotally connected to the upper ends of the gripping arms, and roller

15 lugs fixed on the inside of the gripping levers, the unit is mounted on the yoke, one branch of the rope bending around it is fixed and fitted with a discharge cage attached to it, and the swiveling locking lever is fixed on one of the cargo levers, spring loaded and made two double shoulders, free shoulder which has the shape of a fork for engagement with the discharge clip.

Such an embodiment of the device allows the containers to be opened at any given height.

FIG. 1 shows the load handling device at the moment of container pickup, general view; in fig. 2 - the same, in the open state; in fig. 3 is a section A-A in FIG. one; in fig. 4 shows a section BB in FIG. one.

The load gripping device comprises a yoke 1 (Fig. 1) on which the cargo levers 2 are pivotally fastened and released by springs 3 fixed on the free ends of the cargo levers 2. On the other ends of the levers 2 the gripping levers 4 are hingedly fixed on the inner side of which the roller stops 5 .

On one of the cargo levers 2, the pivoting fixed arm 6 is pivotally fixed, the upper arm of which is made in the form of a fork, which embraces the rope 7 (Fig. 3). The locking lever 6 is held in a neutral state by a spring 8 and is engaged with a stop 9 attached to one of the gripping levers 4. To automatically unload the container, the unloading sleeve 10 is attached to the fixed branch of the rope 7, with which the discharge height of the container 11 is adjusted.

Load handling device operates as follows.

The opened lifting device (the opening is made by springs 3) is lowered onto the container 11, while the gripping levers 4 are diverted and move along the container downwards. When lifting the load gripping device, the roller stops 5 engage with the flanges 12 of the container AND, and the lower part of the gripping arms abut against the walls of the container 11. The turning of the left gripper 4 relative to the cargo lever 2 is eliminated due to the locking lever 6, which engages with the stop 9. When the container is lifted, the locking lever 6 rests on the holder 10 and rotates, releasing the left gripping lever 4. Under the action of the mass of the load and the container 11, the gripping levers 4 turn relative to the cargo levers s 2, which, in turn, pivot about

traverse 1, the container is opened and unloaded (Fig. 2).

After unloading, an empty container is transported to the storage site. After the container is lowered onto the spring storage area 3, returning the load gripping device to the initial position, the grippers 4 are released from the engagement with the container 11.

This structure of the load gripping device is more convenient to use than the known one, since it ensures the opening of the containers at any given height. ,
