A safety hook and its application method

Abstract

The invention discloses a safety lifting hook and an application method of the safety lifting hook and relates to the technical field of hoisting machines. The safety lifting hook solves the problem that goods on a lifting hook cannot form stable self-locking during violent shake, so that safety accidents are prone to happen. The safety lifting hook comprises a lifting hook body. The upper portionof the lifting hook body is provided with a pulley assembly. The safety lifting hook is characterized in that the root portion of the lifting hook body is rotationally provided with a connection plate through an elastic torsion piece, the end, far away from the elastic torsion piece, of the connection plate abuts against the hook point portion of the lifting hook body in a connection manner, a lifting ring is arranged on the connection plate, and the lifting ring is arranged on the lifting hook body in a sleeving manner. The safety lifting hook has good self-locking stability, when goods on alifting sling shake violently, the lifting sling cannot easily disengage from the lifting hook body, so that safety accidents are not prone to happen, and the overall safety lifting hook has a good application effect.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, more specifically, it relates to a safety hook and an application method thereof. Background technique [0002] The hook is the most common type of spreader in hoisting machinery. The hook is often suspended on the wire rope of the hoisting mechanism by means of a pulley block and other components. [0003] The Chinese invention patent with the publication number CN104386577A discloses a suspension hook, which includes a suspension hook body, a pulley assembly is provided on the upper part of the suspension hook body, and a seal for sealing the suspension hook body is provided between the hook tip and the root of the suspension hook body. The insurance card is characterized in that: the two sides of the root of the hook body are provided with two transmission connecting plates extending toward the rear and lower side of the hook body, the two transmission connection plates are arrange...
