Gravity self-locking type lifting hook anti-disengaging device

Abstract

The invention discloses a gravity self-locking type lifting hook anti-disengaging device in the technical field of lifting hook disengaging prevention. The gravity self-locking type lifting hook anti-disengaging device comprises a hook body; an upper slot is formed in the left side wall of the top of the hook body, a lower slot is formed in the lower wall of a hook opening of the hook body, a pushblock contraction cavity is arranged on the left side wall of the lower slot, a push block slide rod is connected to the left wall of an inner cavity of the push block contraction cavity, a push block spring sleeves a rod body of the push block slide rod, and a push block is arranged at the right end of the push block spring; self-locking of a button tooth and the hook body is realized through mechanical matching of the push block, a stop block and a loose pin, the risk of disengaging a lifted object from the hook body is avoided, the button tooth adopts vertical lifting type locking, the space in the inner cavity of the hook body is avoided from being occupied, the hooking and the unloading of the lifted object are avoided being hindered, the time consumed by hooking and unloading the lifted object is shortened, and man power is saved.

Description

technical field [0001] The invention relates to the technical field of lifting hook detachment prevention, in particular to a gravity self-locking lifting hook detachment prevention device. Background technique [0002] The lifting hook is a part used to hang the suspended object when lifting the object. In order to strengthen the safety regulations of the hook operation and ensure the safety of the current lifting operation, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China has promulgated the "Rules for Periodic Inspection of Hoisting Machinery", which clearly stipulates that "the hook is equipped with an anti-decoupling device". [0003] At present, the anti-decoupling devices on the market are heavy. To solve the problem of preventing the hook mouth from detachment of the hook body, only an elastic buckle (also called a blocking block) is added at the hook mouth of the hook body. The hook mouth of the hook bod...

Problems solved by technology

[0007] The object of the present invention is to provide a gravity self-locking lifting hook anti-decoupling device to solve the problem in the above background technology that when the buckle teeth are pulled toward the inner cavity of the hook during the process of loading and unloading the suspended object, the inner cavity of the hook is blocked. The buckle teeth occupy a part, which is easy to hinder the hooking and unloading of the suspended object, prolonging the time-consuming hooking and unloading of the suspended object. During this period, it is necessary to keep applying force to the buckle teeth and push the buckle teeth to The inner cavity is pushed to facilitate the hooking and unloading of the suspended object, which is a relatively laborious problem
