Problems solved by technology

[0002] Hoisting machinery is widely used in various engineering constructions, and construction safety has become the top priority. Therefore, it is indispensable to prevent various accidents, especially for heavy objects hoisted at high altitudes. The safety of items hoisted by hooks is particularly important. , the traditional hook locks the rope manually. This kind of manual hook needs to be manually unlocked when in use, which is very inconvenient and labor-intensive for workers. Self-locking crane hooks that are easy to use, low in labor intensity and low in operating costs are of great significance

Abstract

The invention relates to a self-locking crane lifting hook. The self-locking crane lifting hook comprises a lifting hook body. A cavity is formed in the lower part of the lifting hook body. The cavity is internallyconnected with a spring seat in a clamped mode. The upper end of the spring seat is connected with a bearing plate. The bearing plate is of an arc-shaped structure. The lower part of the spring seat is connected with a spring. The lower end of the spring is connected with the lifting hook body. The outer wall of the middle of the spring seat is provided with a side drawing plate. The lower part of the side drawing plate is hinged to a self-locking plate. The lower part of the self-locking plate is connected with the lifting hook body through a pin shaft. The self-locking crane lifting hook has the advantages of being simple in structure, convenient to use, low in labor intensity and low in running cost.

Description

technical field [0001] The invention belongs to the technical field of hook equipment, and in particular relates to a self-locking crane hook. Background technique [0002] Hoisting machinery is widely used in various engineering constructions, and construction safety has become the top priority. Therefore, it is indispensable to prevent various accidents, especially for heavy objects hoisted at high altitudes. The safety of items hoisted by hooks is particularly important. , the traditional hook locks the rope manually. This kind of manual hook needs to be manually unlocked when in use, which is very inconvenient and labor-intensive for workers. The self-locking crane hook with easy to use, low labor intensity and low operating cost is of great significance. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a self-locking crane hook with simple structure, convenient use, low labor intensit...
