Lifting hook anti-rotation positioning apparatus

Abstract

The invention discloses a lifting hook anti-rotation positioning apparatus, which comprises a cross beam, a pin shaft, a pin, a hook stopping shape plate, a rectangular flat plate, a bolt with slots, a J-shaped baffle, a locking sheet with a keyway, an L-shaped plate, and a lifting hook body, wherein a locking washer with a keyway is arranged on the lifting hook, and the L-shaped plate and the J-shaped baffle are welded on the cross beam so as to indirectly and integratedly fix the lifting hook and the cross beam. The lifting hook anti-rotation positioning apparatus has a characteristic of compact and reasonable structure, wherein the crane lifting hook can be well prevented from rotation during an operation process, and can flexible rotate when the positioning apparatus is uplifted, and the lifted object positioning is easily achieved with the apparatus so as to provide safety and reliability for the whole lifting operation.

Description

technical field [0001] The invention relates to a hook group on a crane, in particular to a hook anti-rotation positioning device. Background technique [0002] At present, the general crane hook load-bearing part is mainly composed of four parts: hook nut, pressure bearing, hook beam, and hook. When the hook carries an object, the hook head will rotate freely. At the same time, during the cooperation process between the beam and the hook, if the gap between the beam and the hook head is too large, the hook head will also have a certain lateral displacement, and the hanging object will easily be separated from other objects. Objects collide, and it is also difficult to place the hoisted objects in place, and the stability is not good, which brings inconvenience and even danger to the hoisting, and buryes a safety hazard for the hoisting operation. Contents of the invention [0003] The purpose of the present invention is to provide a hook anti-rotation positioning device,...
