Crane lifting hook convenient to disassemble

Abstract

The invention discloses a crane lifting hook convenient to disassemble. The crane lifting hook involves a lifting hook connecting frame, a hook replacement connecting plate is connected to the lower end of the lifting hook connecting frame, a detachable lifting hook body is arranged on the hook replacement connecting plate, the lifting hook body comprises a horizontal supporting shaft, a hook head is fixedly connected to the middle of the lower end of the horizontal supporting shaft, and a through groove penetrating through the upper and lower end faces is formed in the hook replacement connecting plate; the lifting hook can be replaced according to different requirements, and the lifting hook can be replaced only by jacking the hook head upwards, rotating the hook head by 90 degrees and finally moving the hook head downwards; meanwhile, a steel wire rope connected with a spring buckle is additionally arranged on the hook, the spring buckle can be opened by pulling the steel wire rope upwards, and when the steel wire rope continues to be lifted upwards, the hook can be inclined, so that the steel wire for hanging heavy objects automatically falls off, the labor intensity of people is greatly reduced, and the working efficiency is improved; and a pressure sensor in contact with the horizontal supporting shaft is arranged at the upper part of a groove, so that whether a hoisted object is overweight or not can be conveniently monitored, and the damage of a crane jib is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of mechanical accessory processing attachments, and in particular relates to a crane hook that is easy to disassemble. Background technique [0002] A crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range, also known as cranes, aerial cranes, cranes, and some lifting equipment. The corresponding mechanisms for actions such as retrieving, transporting and unloading work alternately. The development and use of cranes in the market are becoming more and more extensive. Some accidents often occur due to the lack of outriggers for hoisting and hoisting. [0003] When the crane is in use, the hook is a very important accessory. It is mainly necessary to hook the item through the hook for transportation. The existing hooks are basically one-piece welded structures. It is very inconvenient to disassemble the hook, so Just reduce the pr...
