Hook and hoisting machinery with the hook

Abstract

The invention discloses a lifting hook, which comprises a lifting hook body, a hook body and a driving element of the hook body; wherein, the lower end part of the lifting hook body is movably connected with the upper end part of the hook body; one end of the driving element of the hook body is fixedly connected with the lifting hook body, while the other end of the driving element of the hook body is movably connected with the hook body; by controlling the driving element of the hook body to drive the hook body to open or close, the open-or-close of the lifting hook is automatically realized; in the inventive lifting hook, the driving element of the hook body can be controlled to drive the hook body to open or close so as to realize the automatic hooking or separation of the lifting hook and the lifted goods; the operation is simple and convenient, the working efficiency is improved; manual unhooking and hook lifting are avoided and personal injury accidents of the operating personnel caused by the falling of the lifted goods or the lifting hook in the lifting process are avoided. Furthermore, the lifting hook is free from manual operation, thus being suitable for special working conditions or the lifting of special goods.

Description

Technical field [0001] The present invention relates to the field of hoisting machinery, in particular to a hook used for hoisting machinery. The invention also relates to a hoisting machine with the hook. Background technique [0002] When moving goods in workplaces such as factory workshops or engineering construction sites, hoisting equipment (such as electric cranes or electric hoists, etc.) are usually used to complete the lifting of goods. [0003] When all kinds of lifting machinery are lifting goods, manual operation is required to hook the hanging handle (or the steel rope that binds the goods) of the lifted goods to the hook of the lifting machine, and then the lifting machine lifts the goods , Lift the goods to the designated place, and then separate the lifting handle (or the wire rope that binds the goods) from the hook of the hoisting machine through manual operation, thereby completing the operation process of hoisting the goods by the hoisting machine.

AI Technical Summary

Problems solved by technology

When working, it is necessary for the ground commander to command the crane operator and front-line operators to manually remove and hang the hook, and three (or more) people cooperate to complete the loading and unloading of the goods, thus wasting manpower and low work efficiency

Under special working conditions (such as high temperature and low temperature environment), or when loading and unloading special cargo (such as loading and unloading chemicals, dangerous goods), it is not suitable for the operator to take off the hook or approach the special cargo in this case, so It is difficult to realize the manual operation to remove and hang the hook of the heavy machinery

[0005] Moreover, due to the need for three (or more) people to work together, during the work process, if the operator does not cooperate properly, or the hook of the hoisting machine or the goods to be hoisted falls, the ground commander, the hook removal personnel, etc. cause personal injury
