Problems solved by technology

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 in addition, it is difficult to place the hoisted objects in place, and the stability is not good, which brings inconvenience and even danger to hoisting, and buryes a safety hazard for hoisting operations

Embodiment 1

[0013] Such as figure 1 As shown, a hook anti-rotation positioning device, it includes a beam 1, the outer wall of the beam 1 is respectively provided with a hook-shaped plate 2 and a rectangular flat plate 3, the hook-shaped plate 2 and the rectangular flat plate 3 An L-shaped plate 4 connected by a pin shaft is arranged between them. The lower part of the rectangular flat plate 3 is connected with a J-shaped baffle plate 5 matched with the hook-shaped plate 2 through bolts, and the lower part of the beam 1 is connected with a hook body. 6. The outer wall of the upper part of the hook body 6 is provided with a locking piece 7 with a keyway that matches the L-shaped plate 4 .

[0014] When the present invention is in use, before hoisting the object, the L-shaped plate is pressed against the J-shaped baffle, and the whole set of device is in a loose state. In the groove, put down the J-shaped baffle and block the hook-shaped plate, so that the J-shaped baffle presses the L-sha...

Abstract

The invention relates to an anti-rotation lifting hook positioning device. The device comprises a beam, wherein stop hook plates and rectangular flat plates are respectively arranged on outer walls of the beam; L-shaped plates connected through pin shafts are arranged between the stop hook plates and rectangular flat plates; the lower parts of the rectangular flat plates are connected with J-shaped baffles matched with the stop hook plates through bolts; a lifting hook body is connected to the lower part of the beam; and locking pieces with key grooves matched with the L-shaped plates are arranged on outer wall on the upper part of the lifting hook body. The anti-rotation lifting hook positioning device disclosed by the invention has the advantages of being simple in structure, convenient and rapid to use, capable of solving the problem that the hook head randomly rotates, high in bearing capacity, convenient to place a lifting cargo and safe and reliable to use.

Description

technical field [0001] The invention belongs to the technical field of lifting hooks, 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 overcome the deficiencies of the pr...
