AI Technical Summary

Technical Problem

The existing construction crane hooks are prone to fall off and shake due to wind force when operating at high altitudes, which poses safety hazards.

Method used

An anti-detachment mechanism is designed, including a hook unit and an anti-detachment unit. The hook unit includes a hook, a compartment and a reflective strip, and the anti-detachment unit includes a plug rod and a threaded head. Through the cooperation of these components, the suspender is limited between the plug rod and the hook to avoid falling off, and the suspender is stably limited through the compartment and through the through groove to prevent shaking.

Benefits of technology

It effectively avoids the lifting and shaking of the suspender due to wind during high altitude operations, improves the safety of the use of the hook, and maintains the stability of the device during high altitude operations through counterweight components.

Abstract

The utility model relates to the technical field of anti-dropping lifting hooks, in particular to an anti-dropping mechanism and a building crane lifting hook, which comprises a lifting hook unit, a lifting hook, an interlayer arranged on the lifting hook and a reflective strip arranged on the lifting hook. And the anti-falling unit comprises an inserting rod arranged on the lifting hook in a sliding manner and a threaded head arranged on the inserting rod. The lifting belt is moved to the inner side of the lifting hook, then the threaded head is matched with the threaded blind hole, so that the lifting belt is limited between the inserting rod and the lifting hook, the situation that the lifting belt is disengaged from the lifting hook in the operation process due to heavy high-altitude operation wind is avoided, meanwhile, the lifting belt is stably limited through the arranged penetrating groove and the interlayer, and the safety of the lifting belt is improved. The lifting belt is prevented from sliding on the peripheral surface of the inner side of the lifting hook, and the situation that the lifting belt is unstable due to strong wind during high-altitude operation, so that lifted goods shake and danger is caused is avoided.
