Description

A kind of up-down structure suspension hook

Technical field

The utility model relates to a kind of suspension hook, relates in particular to a kind of up-down structure suspension hook.

Background technology

Suspension hook is modal a kind of suspender in elevator machinery.Suspension hook often is suspended on the steel rope of lifting mechanism by means of parts such as assembly pulleys, and suspension hook is divided into single hook and double hook by shape, and single hook manufacturing is simple, easy to use, but stressing conditions is bad, mostly is used in hoisting capacity little workplace; Hoisting capacity adopts the double hook of stressed symmetry greatly often.The utility model provides a kind of up-down structure suspension hook by existing double hook is improved, and this suspension hook contains four gib heads, can use simultaneously four gib heads to increase the stress balance of suspension hook, has increased hoisting capacity, uses flexible, convenient.

The utility model content

The purpose of this utility model is to provide a kind of up-down structure suspension hook, increases the stress balance of suspension hook, increases hoisting capacity.

The utility model provides a kind of up-down structure suspension hook, comprise a hook neck, two upper hook bodies, wherein, two upper hook bodies are connected with the bottom of hook neck, it is characterized in that, also comprise two lower hook bodies, the top of two lower hook bodies is connected with the middle part of upper hook body respectively, and the gib head of lower hook body is towards the inboard of suspension hook.

The user can be according to density, the different gib head of shape choice for use of weight, can two gib heads of choice for use, sometimes for the stress balance that increases suspension hook or increase hoisting capacity, the user can use four gib heads simultaneously, and usage comparison is simple, convenient, flexibly.

The beneficial effects of the utility model are: this up-down structure suspension hook, usage comparison is simple, convenient, flexible, has increased the stress balance of suspension hook, has increased hoisting capacity.
