Abstract

The invention relates to mining and can be used for excavation. The purpose of the invention is to reduce the metal content. The grapple is suspended by means of a locking 3 and lifting 4 ropes (K) to the drum (B) 2 winches located on the platform 1 of the base machine. The lower ends of the K 3 and 4 are connected respectively with the lower 6 and upper 8 heads. The jaws 5 are pivotally connected to the head 6 and by means of the tg by the 1st head 8. The platform 9 and the hydraulic cylinder 11, which are pivotally connected to each other, are pivotally connected to platform 1. The block 10 of the backstage is pressed against K 4. The opening of the jaws 5 is made by moving the backstage 9 and tensioning K 4 by the block 10. The closing of the jaws is made by moving the backstage 9 in the opposite direction. The grab is lowered or raised by simultaneously squeezing or winding K 3 and 4 by rotating B 2. 1 sludge. (L

The invention relates to mining and to the lifting and transport machinery and can be used in the development of soil grab trenching, lifting goods, etc.

The chain of invention is the reduction of metal consumption,

The drawing shows the device for the development of soil j total

The device for excavation consists of a base machine (excavator) (not shown), on the platform 1 of which is installed lr. with a barz. ™ ban 2, A grab (not shown) is suspended by the locking 3 and lifting 4 ropes to the arrow of the base machine. The grab includes the jaws 5, pivotally interconnected by means of the lower head 6, and by means of two tg 7 - with the top head 8. Both ropes 3 and 4 are connected to the drum 2 of the winch. The free ends of the ropes 3 and 4 are connected, respectively, from the bottom 6 to the top 8 heads of the grapple,

On the platform, a hinge was installed: on the link 9 and on its bed, a block 105 was attached, which was covered by a lifting rope 4. To prevent it from getting stuck, the hydraulic reservoir 11 was raapfflipHo, which was connected with platform 1 and slide 9 o.

works in the following way.

In order to open the jaws 5, the rod of the hydraulic cylinder 11 is moved by a slider 9 and associated with it. block 10 upper position. The lifting rope 4 is tightened and the head 6 is shifted down under the influence of its own weight, the jaw divorce 5. At the same time 79 .7

By running down the cables 3 and 4 from the drum 2 of the winch, the jaws 5 are lowered.

To scoop the cargo, the rod of the hydraulic cylinder 11 is retracted, lowered into position 9 with block 10, thereby weakening the tension of the hoisting rope 4. When the drum 2 rotates, ropes 3 and 4 roll over it, the lower head 6 rises and closes the jaws 5 With further winding ropes 3 and 4 on the drums 2 of the jaws 5 are lifted with a load.

To unload the jaws 5 and the hydraulic cylinder 11, moves the slide 9 with the block 10 to the upper position, pulling the 4 cable up. Jaws 5 open.
