A kind of flexible buffer crane hook

Abstract

The invention discloses a flexible buffer crane hook, which comprises a pulley block mechanism, a flexible buffer mechanism and a hook mechanism. The pulley block mechanism, the flexible buffer mechanism and the hook mechanism are arranged sequentially from top to bottom; the flexible buffer mechanism The mechanism includes a flexible buffer beam, a main frame, two elastic members and two idlers arranged in parallel. The flexible buffer beam is built into the main frame, and the two sides of the flexible buffer beam are symmetrically provided with arc load-bearing surfaces. , the two supporting rollers are slidingly connected with the main frame, the opposite sides of the two supporting rollers are respectively tangent to the two arc load-bearing surfaces, and the opposite sides of the two supporting rollers are respectively connected to the Two elastic parts are connected, and the two elastic parts are fixed on the main frame; when the hook is lifting and unloading goods in the prior art, the force of the whole lifting system changes sharply, especially when the load is too large When the system is under severe force conditions and the goods are picked up and placed, there are huge technical problems.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a flexible buffer crane hook. Background technique [0002] The crane hook is one of the important parts of the crane, and the crane hook is usually used in conjunction with the pulley block. The hook pulley block usually consists of a left vertical plate, a right vertical plate, a vertical plate connecting rod, a pulley shaft, a pulley block, a beam and a hook. At the bottom of the board, the hook is installed on the beam. [0003] When the ordinary hook pulley block works, the crane wire rope bypasses the pulley block, and the pulley block is lifted and lowered through the wire rope retraction, thereby driving the vertical plate and the hook to lift. Analyze the mechanical characteristics of ordinary hooks. When the cargo is lifted and unloaded (the moment the cargo lands or lifts off the ground), the force on the entire lifting system changes sharply, especiall...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the above-mentioned technical deficiencies and provide a flexible cushioning crane hook to solve the problem that the force of the entire lifting system changes sharply when the hook is lifting and unloading goods in the prior art, especially when the load is too large. The system is subject to severe stress and the technical problem of huge impact when picking and placing goods
