Abstract

IsoGre en / e relates to lifting and transport equipment, in particular to a gripping device. The purpose of the invention is to improve the reliability of gripping. The lifting device contains an L-shaped bearing element 1 with support 2 for cargo 1 and an articulated parallelogram 9 with blocks 4, 8, 15 with a cable 6, which ensures the summation of the compression forces of 3 silt

Description

The invention relates to lifting and handling equipment, in particular to load handling devices.

The aim of the invention is to improve the reliability of the capture

Fig. 1 shows a load gripping device: Fig. 2 is a diagram of the action of gripping; Fig. 3 is a section A-A in Fig. 1.

The load gripping device contains an L-shaped carrier 1 with support 2 for load 3 and a block 4 in the upper part of the vertical flange of element 1, a two-arm lever 5 with a cable 6, a rod 7 and a hinge rod 8 connected to element 1 and a two-arm lever 5 in the parallelogram mechanism 9 with hinges 10, 11, 12, 13. In this case, the hinge 10 of the two shoulders lever 5 is located on the element 1 between the support 2 and the block 4, the hinge 11 of the rod 7 is made at the end of the two shoulders lever 5 installed block 15. which is connected by cable 6 to block 16, by the rounding of the end of the hinge bar 8. Element 1 and double-arm lever 5 are connected by a cylindrical tension spring 17.

During operation, the device is suspended by the cable 6 on the hook of a hoist MO / AN / ZMA, for example, a truck crane. The cable is hooked to the base of the crane crane, which, when sagging loose, the wasp creates orientation of the device along the trill.

Movement of the boom on the hook rocks t to the load - the extracted plate and horizontal movement of the hook will be placed on the edge of the plate by the movement of the boom. The hook is then raised. In this case, the support 2 is braked by the plate, the cable 6, overcoming the tension of the spring 17, turns the double-arm lever 5 and the hinge rod 8, which ensures double driving of the block 20 - forces acting on the block 20 from the side of the double-arm lever 5

and ball joint 8, summarized. Block 20 attaches the plate to the support 2 with a force greater than the tension of the cable 6, and holds the plate during lifting. The most loaded part of the pads 20, located closer to the vertical shelf of the element 1.

When fully lowering the slab to the ground or to the transport platform, the spring 17 pulls the pad 20 away from the slab. After that, the movement of the hook along the plate frees the lifting device.

The initial equilibrium clearance between the support 2 and the device's pressure pad 20, suspended from the hook and free from the load, is determined by the rigidity of the spring 17, which is stretched by a force depending on the weight of the device itself. If the load handling device is lowered to the ground, the weight of the device ceases to act on the cable 6, and the gap under the influence of the spring 17 becomes greater than the equilibrium. After the latch is latched — the ball 21 enters the hole 22 — the increased clearance is maintained when the device is lifted without a load. When adjusted, the retainer can withstand the weight of the device, but it disengages when the tension of the cable 6 rises in the process of seizing the load. The degree of fixation — from seizure to complete shutdown — is controlled by changing the gap between the leaf spring and element 1.
