Mechanism used for preventing sliding-down of crane hook

Abstract

The invention relates to a hook part of a crane, specifically to a mechanism used for preventing sliding-down of a crane hook. The mechanism comprises a hook body and a tongue connected with the rod part of the hook body. The mechanism is characterized in that the rod part of the hook and the tongue are fixed through a pin, a torsion spring is sleeved on the pin, one end of the torsion spring leans against the inner side of the rod part of the hook, the other end of the torsion spring leans against the inner side of the tongue, the sharp-pointed part of the hook body is provided with a wedge groove and the end part of the tongue is located in the wedge groove. Compared with the prior art, the invention has the following advantages: sliding-down of a rope hanged on the hook is effectively prevented through the tongue, so damage of equipment and casualties are avoided.

Description

[technical field] [0001] The invention relates to a crane hook component, in particular to a crane hook anti-slip mechanism. [Background technique] [0002] At present, the existing crane hooks generally do not have an anti-slip mechanism of the hook. During the work, the ropes for hanging the goods may slip off from the hook, causing equipment damage, and serious accidents that may cause casualties. [Content of the invention] [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a hook anti-slip mechanism for preventing ropes from slipping. [0004] In order to achieve the above purpose, a crane hook anti-slip mechanism is designed, which includes a hook body and a tongue connected to the hook body rod, which is characterized in that the hook rod and the tongue are fixed by a pin , and set a torsion spring on the pin shaft, one end of the torsion spring rests on the inner side of the hook rod, the other end leans on t...
