The technical scheme adopted by the utility model is as follows: the utility model provides a large-scale lifting hook unhooking-preventing device, includes lifting hook body, unhooking-preventing frame, pin, lifting hook body upper portion one side is equipped with first adapter sleeve, unhooking-preventing frame includes two long limits, first connection horizontal limit, two minor faces, second connection horizontal limit, second adapter sleeve, first "U" shaped frame is constituteed with first connection horizontal limit to two long limits, second "U" shaped frame is constituteed with second connection horizontal limit to two minor faces, first "U" shaped frame opening part is connected with second "U" shaped frame opening part, the position of connection is equipped with the second adapter sleeve, second adapter sleeve and first adapter sleeve are passed by the pin, pin one end is equipped with the screw thread, be equipped with the nut on the screw thread, the contained angle that first "U" shaped frame and second "U" shaped frame are connected forms is the acute angle, unhooking-preventing frame can the pin for the axle rotation;
further, a wear-resistant rubber sleeve is sleeved on the second connecting transverse edge;
furthermore, the two long sides, the first connecting transverse side, the two short sides and the second connecting transverse side are hollow steel pipes.
When no external force acts, the anti-unhooking rack can rotate by taking the pin as the shaft, and when the whole anti-unhooking rack needs to be balanced, the second connecting transverse edge can move towards the end part of the hook of the lifting hook, and the second connecting transverse edge is contacted with the lifting hook, so that the aim of unhooking is fulfilled.
The utility model has simple structure, safety, reliability and convenient use, when the belt or the steel rope is needed to be hung on the lifting hook, the first connecting transverse edge is only needed to be lifted, the belt or the steel rope is hung on the lifting hook, the labor intensity is reduced, and the potential safety hazard of falling of the belt or the steel rope is avoided.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model.
Fig. 2 is a schematic view of a hook body according to the present utility model.
FIG. 3 is a schematic view of the anti-drop frame of the present utility model.
Fig. 4 is a schematic view of a pin according to the present utility model.
In the figure: 1. the lifting hook comprises a lifting hook body, a first connecting sleeve, a drop-off preventing framework, a long side, a first connecting transverse side, a short side, a second connecting transverse side, a second connecting sleeve and pins.
Detailed Description
In order to make the technical solution of the present utility model more clearly understood, the present utility model will be further described with reference to the accompanying drawings.
As shown in fig. 1-4, the large-scale lifting hook unhooking prevention device comprises a lifting hook body 1, a unhooking prevention frame 2 and a pin 3, wherein one side of the upper part of the lifting hook body 1 is provided with a first connecting sleeve 101, the unhooking prevention frame 2 comprises two long sides 201, a first connecting transverse side 202, two short sides 203, a second connecting transverse side 204 and a second connecting sleeve 205, the two long sides 201 and the first connecting transverse side 202 form a first U-shaped frame, the two short sides 203 and the second connecting transverse side 204 form a second U-shaped frame, the second connecting transverse side 204 is sleeved with a wear-resistant rubber sleeve, the wear of the second connecting transverse side 204 and the lifting hook body 1 is reduced, the first U-shaped frame opening part is connected with the second U-shaped frame opening part, the position of connection is provided with a second connecting sleeve 205, the second connecting sleeve 205 and the first connecting sleeve 101 pass through by a pin 3, an included angle formed by the connection of the first U-shaped frame and the second U-shaped frame is an acute angle, one end of the pin 3 is provided with threads, nuts are arranged on the threads, the anti-falling hook frame 2 can rotate by taking the pin 3 as an axis, and the two long sides 201, the first connecting transverse side 202, the two short sides 203 and the second connecting transverse side 204 are hollow steel pipes.
When the belt or the steel rope is required to be hung on the lifting hook, only the first connecting transverse edge 202 is required to be lifted, enough space for the belt or the steel rope to pass through is reserved between the second connecting transverse edge 204 and the lifting hook body 1, after the belt or the steel rope is hung, the first connecting transverse edge 202 is put down, so that the unhooking prevention rack 2 is self-locked, namely when no external force acts, the unhooking prevention rack 2 can rotate by taking the pin 3 as a shaft, when the whole unhooking prevention rack 2 needs to be balanced, the second connecting transverse edge 204 moves towards the end part of the lifting hook, the second connecting transverse edge 204 is in contact with the lifting hook body 1, and no gap exists between the second connecting transverse edge 204 and the lifting hook body 1, so that the purpose of unhooking prevention is achieved.
The utility model has simple structure, safety, reliability and convenient use, reduces the labor intensity of workers and avoids the potential safety hazard of falling of the belt or the steel rope.
The foregoing description is only of the preferred embodiments of the utility model, and all changes and modifications that come within the meaning and range of equivalency of the structures, features and principles of the utility model are therefore intended to be embraced therein.
