Hoisting unhooking prevention device

Abstract

The invention discloses a hoisting unhooking prevention device, and belongs to the technical field of hoisting equipment. The hoisting unhooking prevention device comprises a hoisting shackle, a shackle column, a shackle locking assembly, a limiting pull rod and a shackle limiting assembly. The shackle locking assembly comprises a supporting ring, a locking ring and a shift ring, wherein the supporting ring is arranged in a ring, the locking ring is arranged in a ring, the locking ring and the supporting ring are arranged in a concentric circle, the shackle limiting assembly comprises a limiting sleeve box, a self-adaptive limiting block and a hinged shaft, and a friction limiting layer is arranged on the side, close to the shackle column, of the self-adaptive limiting block. The hoistingequipment particularly relates to the hoisting unhooking prevention device that can precisely adjust the tightness of the locking assembly, can limit a hoisting rope into the hoisting shackle withoutunhooking, can enable different types of hoisting shackles and shackle heads of the limiting hoisting shackle to be matched through the self-adaptive function of the shackle limiting assembly, plays arole of sealing the hoisting shackle, and further prevents unhooking.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to an anti-decoupling device for hoisting. Background technique [0002] In the steel production process, whether it is packaging, stacking and other operations, it is necessary to use a crane to lift the steel back and forth. The hoisting device is a hoisting device used to cooperate with the crane to lift the steel pipe to achieve the purpose of transferring the steel pipe. In the past multi-hook hoisting device, because the tightness of the hook and the hook cable is extremely difficult to control, when the steel pipe is hung, the phenomenon of automatic decoupling often occurs. The operator has to hang it several times to hang it well, which is time-consuming and labor-intensive, which seriously affects the hoisting efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a hoisting anti-decoupling device, which can precisel...
