Self-balancing anti-disengagement crane hook with auxiliary hook

Abstract

The invention discloses a self-balancing anti-disengagement crane hook with an auxiliary hook, and belongs to crane hooks. The self-balancing anti-disengagement crane hook with the auxiliary hook comprises a hook body, wherein a main auxiliary hook and an auxiliary auxiliary hook are arranged on the lower side of the hook body, and the auxiliary auxiliary hook is located at the lower side of the main auxiliary hook. According to the crane hook, the main auxiliary hook and the auxiliary auxiliary hook with different angles are arranged on the lower side of the hook body, the main auxiliary hook, the auxiliary auxiliary hook and the hook body are in a free rotation state, on the basis that lifting and transferring of heavy objects by the hook body are not affected, when the hook body inclines, the main auxiliary hook and the auxiliary auxiliary hook can automatically adjust positions and angles thereof under the action of self weight, then a balance state is formed, a heavy object is secondarily hooked when the heavy object is gradually separated from the hook body, falling time of the heavy object is delayed, time is provided for finding and processing of workers, and therefore an accident rate of falling of the heavy object is reduced, and use safety of a crane is greatly improved.

Description

technical field [0001] The invention relates to a crane hook, in particular to a self-balancing anti-off crane hook with an auxiliary hook. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. During the use of the crane, the heavy objects are usually hoisted on the hook assembly through the ropes, and the lifting and horizontal handling of the heavy objects are realized through the power system. [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. Contents of the invention [0004] 1. Technical problems to be solved [0005] Aiming at the problems existing in the prior art, the object of the...
