SU742339A1 - Device for putting slings off a hook - Google Patents

Description

FIELD OF THE INVENTION The invention relates to lifting machinery, and it is referred to mechanical sling devices. A device is known that provides automatic dropping of strops when placing a load on a support and containing a traverse suspended on a crane hook, with hooks for slings and a cranked rotary shaft with a stop interacting with the load 1. However, lining up with such a device, weights of complex configuration that do not have a support surface for the stop are impossible. The closest technical solution to the present invention is a device for dropping cargo slings from a hook, which contains a drop bracket and an emphasis fixed to the hook by means of a finger with a cotter pin 2. However, the use of such devices for unraveling spatial lattice structures, shells or ducts is difficult because it is necessary to create stops for the drop-down bracket, and it is not possible in cases where it is necessary to drop all the lines from the hook. In addition, it is necessary to apply sufficiently large forces to drop the slings by known devices. The purpose of the invention is to ensure the distribution of cargo of any type of conformation. For this, the device is equipped with a spring-loaded carabiner mounted on a finger and a cross member with a cable-blocking system, carrying a remote control cable, interacting with the carabiner and a drop clevis. The drawing shows a proposed device for dropping a cargo slings from a hook, a general view. The device consists of a crane hook 2 fixed to the tube 1 by means of a finger 3 with cotter pins, an emphasis 4 with a drop-down bracket 5 and a spring-loaded carabiner 6 fixed on the same finger to prevent the lines from falling out 7. The device also contains a cable block system 8 mounted on the yoke 9, which is connected to the remote control cable 10. The cable system 8 with the crosshead 9

connects cable 10 with bracket 5 and carbine b.

The device works as follows.

with; crane hooks remove the projected carbine. The tube 1 welded to the hook 2 is secured with the aid of a finger 3 with locking pins an emphasis 4 with a dropping cleat 5 and a spring-loaded carabiner b. A cable-blocking system S is connected to the dumping bracket 5 and the spring-loaded carabiner 6 through the yoke 9 to the cable 10 to be dropped.

For slinging the load, the spring-loaded carabiner b is manually removed and the slings are put on hook 2, after which the Carabiner b is reset to its original position.

After installation of the cargo in the project, the position of the cargo lines 7 is weakened. By manually tensioning the remote control cable through the yoke and the cable-block system 8, the spring-loaded carabiner 6 is pulled out as far as the hook 2 and released from the hook gap to pass the slings / ... Further tension of the cable 10 through the beam 9 and the cable-block system 8 rotates the ejection bracket 5, which picks up the lines 7 and removes them from the throat of the hook 2. By the movement of the hook 2, it is released from the lines 7 After the cable 10 is loosened, the ejection bracket 5 under its own weight is lowered to its original position. Carabiner 6 under the action of the spring closes the mouth of the hook 2.

The use of the proposed device allows, due to the presence of the Tieblock system with a traverse, to drop the slings when moving any cargo, regardless of its configuration, and also to reduce the effort when dropping the slings. The carbine connected to the block system and its spring-loaded design increase safety

 the work of installers when transferring cargo by crane.
