(54) LOADING DEVICE

(57) The invention relates to lifting and transport equipment and can be used in any area of national economy for loading and unloading operations. The purpose of the invention is to increase reliability. Load gripping

The device contains a swivel hook I, which is hung on a lifting mechanism using a load rope 2, a hook idling mechanism including a spring insert 4 fixed on the rope 2 to form a compensating loop 3, a safety swivel bracket 5 placed in the hook cavity 6 , a cable 10 with a spring insert 11, which is fastened at one end to the bracket 5, and the other on the load line 2. Due to the difference in lengths of compensating loops 3 and 14, as well as the difference in stiffness of the spring insert I1 and the spring 9 swivel bracket 5, when the g is loaded, the hook overlaps its mouth, 16 with any unforeseen exposure to it from outside. 2 Il.

The invention relates to lifting equipment and can be used in any area of the national economy for loading and unloading.

The purpose of the invention is to increase reliability.

Fig. 1 shows the device, the unloaded state of 1a; in Fig. 2, the same, the loaded state.

The load gripping device contains a swivel hook that hangs onto the load-lifting mechanism using a load rope 2, a hook idling mechanism that includes a spring box 4 fixed to the load rope 2 to form a compensating loop 3 and a swing knob 5. The hook body has - an axle 6 and a through-hole 7 associated with it. The safety element 5 is a swivel bracket placed in the cavity 6 on the axis 8, podrushnennoy spring 9. The device is equipped with a cable 10 with a spring insert 11. Od In the end 12 of the cable 10 is fixed on the cargo cable 2 at the point of attachment of the spring insert 4 of the idling mechanism, another horse 13 is passed through the through hole 7 and the cavity 6 in the body of the hook 1 and fixed on the swivel bracket 5 to form an additional compensating loop 14. With this the spring of the spring insert 11 is stiffer than the spring of the spring 9 of the bracket, and the additional compensating loop 14 is shorter than the main compensating loop 3.

The device works as follows.

The horn 15 of the hook I forms the main shed 16 of the hook, in which is placed the shaft of the swivel bracket 5 forming the sliding shed 17.

In the unloaded condition, the load gripping device occupies the position shown in FIG. Turning

bracket 5 is set mainly

A hook with a clearance of 16 hooks with a horn 15.

The loop (ring) 18 of the load passes through the gap between the horn 15 and the pivot bracket 3, is placed in the sliding shed 17 and hangs on the pivot bracket 5.

When the load is lifted, the body of the hook 1 rotates counterclockwise,

the bracket 5, overcoming the force of the spring 9, rotates on its axis 8 and overlaps the shed 16, preventing the loop 18 from falling out of the shed. With a further lifting of the load, the hook 1 rotates and takes the position indicated in Fig. 2, the loop 18 slides off the swivel bracket 5 and hangs on the horn 15 of the hook 1. The spring 4 expands, the main 3 and the additional 14 compensating loops decrease, and As an additional compensating loop 14 is shorter than the main compensating loop 3, the spring of the spring insert 11 is stretched, which locks the pivot bracket 5 in the closed position through the cable 10.

When the hook 1 is subjected to force from unforeseen obstacles in the way of lifting the load, the hook 1 rotates clockwise, while the spring of the spring insert I1 begins to compress due to rigidity, greater rigidity of the spring 9 of the swivel bracket 5 in the closed position, until the loop 18 will not slip onto the pivot bracket 5 preventing it from falling out.

When the load is put in place, the hook turns and the springs of the spring inserts 4 and 11 begin to compress. The spring of the spring insert 11 moves less than the spring travel: the spring insert 4, the rotation of the swivel bracket 5 takes place before the hook turns, since the latter takes place only after the spring of the spring insert 4 is fully compressed. Loop 18 of the load leaves through the gap between the horn 15 and swivel bracket 5. The hook is ready to lift the next load.

Claims (1)

Invention Formula A load gripping device containing a vertical pivot hook mounted on a lifting mechanism using a load rope, a hook idling mechanism including a spring insert fixed on the load rope to form a compensating loop, and a safety element mounted with the possibility of overlapping the hook hook, characterized by that, in order to increase reliability, the swivel hook is made with the cavity and the through hole adjoining it, the safety element is a cavity disposed in the rotary sub springing bracket, and the device snabzhe- but rope with a spring insert, one end of which is fixed on the hoist rope attachment point at the top for insertion therein of the spring mechanism ho- and the other end is passed through the through hole and cavity in the body of the hook and fixed on the swivel bracket with the formation of an additional compensating loop, the cable spring is made with rigidity, greater rigidity of the spring of the rotary bracket, and the additional compensator loop is shorter than the main one.
