Anti-separation lifting hook for crane

Abstract

The invention discloses an anti-separation lifting hook for a crane. The anti-separation lifting hook comprises a lifting hook body. An anti-separation mounting seat is arranged at the upper end of the lifting hook body and internally provided with a vertical slide way. A sliding block capable of moving up and down along the vertical slide way is arranged on the vertical slide way. The sliding block is provided with a vertically arranged anti-separation rod which is tightly attached to one side of the anti-separation mounting seat. The anti-separation rod and the sliding block are integrally formed, and the anti-separation rod is connected with the anti-separation mounting seat through a moving handle. A groove is formed in the inner wall of a hook tip of the lifting hook body, the bottom end of the anti-separation rod can be sleeved with the groove, and the groove is matched with the bottom end of the anti-separation rod in shape. The anti-separation lifting hook is provided with the anti-separation rod which can move up and down along the vertical slide way through the moving handle, opening and closing of the lifting hook body are achieved conveniently and rapidly, operation is easy and convenient, labor is saved, work efficiency is high, and anti-unhooking performance is good; and the lifting hook is low in weight, high in strength, long in service life, good in practicability and worthy of wide popularization.

Description

technical field [0001] The invention relates to a construction machine, in particular to a detachment-preventing hook for a crane. Background technique [0002] Cranes, also known as cranes, refer to multi-action hoisting machinery that vertically lifts and horizontally transports heavy objects within a certain range. The working characteristic of the crane is to do intermittent movement, that is, the corresponding mechanisms for taking materials, moving, and unloading in a working cycle are alternately working, and are widely used in industrial production, construction, freight terminals, warehousing and other industries. , mainly used to lift various goods. In addition to the power unit and the steel rope for hoisting, there are also hooks on the crane, and the hook is an important part of the crane. It plays an important role in the whole lifting process and bears all the loads of lifting. Its Safety directly affects the operation of the crane. During use, once the hook...

AI Technical Summary

Problems solved by technology

However, the anti-off design has the following defects: because the anti-off rod is close to the inner wall of the hook tip of the hook body, when taking out or replacing the sling, it is necessary to artificially press down the anti-off rod toward the inner space of the hook body , if the sling is heavy, two people are required to complete the operation, which is a waste of manpower; in addition, since the anti-off rod occupies the opening area of ​​the hook body, if the size of the sling is large, it will The opening area is small, which increases the difficulty of replacing or taking out the sling and reduces work efficiency
