A self-balancing anti-dropping crane hook with auxiliary hook

Abstract

The invention discloses a self-balancing anti-dropping crane hook with an auxiliary hook, belonging to a crane hook. A self-balancing anti-dropping crane hook with an auxiliary hook comprises a hook body and a lower side of the hook body. The main and auxiliary hooks and the auxiliary auxiliary hooks are provided, and the auxiliary auxiliary hooks are located on the lower side of the main and auxiliary hooks. The hook and the hook body are in a free rotation state. On the basis of not affecting the lifting and transferring of heavy objects by the hook body, when the hook body tilts, the main auxiliary hook and the auxiliary auxiliary hook can automatically adjust themselves under the action of their own weight. The position and angle form a balanced state, and when the heavy object is gradually separated from the hook body, it acts as a secondary hook for the heavy object, delays the falling time of the heavy object, and provides time for the staff to find and deal with it, thereby reducing the weight of the heavy object. The incidence of falling accidents has greatly improved the safety of the crane.

Description

technical field [0001] The present invention relates to a crane hook, more particularly, to a self-balancing anti-dropping crane hook with an auxiliary hook. Background technique [0002] Crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range. During the use of the crane, the heavy object is usually hoisted on the hook assembly through the rope, and the lifting and horizontal handling of the heavy object is realized through the power system. [0003] During the use of the crane, due to accidents or failures, the hoisted heavy objects, hoisting ropes or slings often fall out of the hook mouth and cause the accident to fall. The hook falls off and a safety accident occurs. SUMMARY OF THE INVENTION [0004] 1. Technical problems to be solved [0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a self-balancing anti-dropping crane hook wi...

Problems solved by technology

[0003] During the use of the crane, due to accidents or failures, it often happens that the heavy object being lifted, the hoisting rope or the sling falls out of the hook, and the relative displacement of the heavy object rope and the hook causes it to fall from the hook. The hook fell off and a safety accident occurred
