The lower end of two cramping bodies is fixedly connected by rigid member, and the upper end of the first cramping body and the second cramping body is bolted company
Connect, hanger bulk is fixed on the upper end of the first cramping body.
In the operation such as insulator chain is replaced, the utility model can substitute shackle, for insulation strut, pull rod, hang
Bar and steel wire rope etc. connect, and the hanger bulk of the utility model specifically is hooked in insulation strut or pull rod or sunpender or steel wire
On rope, then by the rope for lifting insulator chain through the first cramping body and the second cramping body of rope connecting portion
Gap, the upper end of rope are bundled on rigid member, and the lower end of rope is fixedly connected with insulator chain lifting device, at this time using exhausted
Insulator chain can be lifted and replaced by edge substring lifting device.
One kind as the utility model is improved, and the hanger bulk, the first cramping body and the second cramping body are all by steel
Plate is made.
One kind as the utility model is improved, and the rigid member is fixed seat, and the both ends of fixed seat are pressed from both sides with first respectively
Body and the second cramping body integrated molding are held, and fixed seat is provided with hollow hole.
Further, outer circumferential surface of the fixed seating between the first cramping body and the second cramping body on the inside of gap is light
Sliding arc surface.
Compared with prior art, the utility model has the following advantages：
The utility model can substitute shackle in the operations such as insulator chain are replaced, and can meet the work for replacing bunch of insulator
Industry demand, makes power tool lighter, can also mitigate the labor intensity of on-site personnel.
Brief description of the drawings
Fig. 1 is the schematic diagram that the utility model is used to replace the hook of insulator chain；
Fig. 2 is the left view of Fig. 1.
Embodiment
The content of the utility model is described in further details with reference to the accompanying drawings and detailed description.It is appreciated that
, specific embodiment described herein is used only for explaining the utility model, rather than the restriction to the utility model.In addition
It should also be noted that, for the ease of describing, part relevant with the utility model rather than full content are illustrate only in attached drawing.
Embodiment
Fig. 1 is refer to, a kind of hook for being used to replace insulator chain, it includes hanger bulk 10 and rope connecting portion 20.
Rope connecting portion 20 includes the first cramping body 21 and the second cramping body 22, the first cramping body 21 and the second cramping body 22
Opposite to separatedly setting, the first cramping body 21 is fixedly connected with the lower end of the second cramping body 22 by rigid member 23, the first folder
The upper end that body 21 is held with the second cramping body 22 is fixedly connected by bolt 24, and hanger bulk 10 is fixed on the upper of the first cramping body 21
End.
In the operation such as insulator chain is replaced, the utility model can substitute shackle, for insulation strut, pull rod, hang
Bar and steel wire rope etc. connect, and the hanger bulk of the utility model specifically is hooked in insulation strut or pull rod or sunpender or steel wire
On rope, then by the rope for lifting insulator chain through the first cramping body and the second cramping body of rope connecting portion
Gap, the upper end of rope are bundled on rigid member, and the lower end of rope is fixedly connected with insulator chain lifting device, at this time using exhausted
Insulator chain can be lifted and replaced by edge substring lifting device.The utility model is relative to shackle, the spy with install convenient
Point, hanger bulk need to only be hung over be hooked object；And the mechanical strength of the utility model hook is the 5 of common shack
Times, meet the work operation of equivalent diameter steel wire rope and insulation branch, draw, the requirement of mechanical strength of sunpender, while maintain cost；This reality
Coordinated with novel hook by rope and insulator chain lifting device to replace insulator chain, electrical insulation properties are good, can be with
Meet live-working safety distance, while be also suitable power failure operation；The utility model hook weight for conventional tool 15%-
20%, greatly save the labor intensity of field work and working at height personnel.
In the present embodiment, the hanger bulk 10, the first cramping body 21 and the second cramping body 22 are all made of steel plate.
The hanger bulk of tabular and the contact area bigger for being hooked object, thus hanger bulk energy hook obtain it is more steady；First folder of steel plate
Hold body and the second cramping body and can contact area bigger with rope so that rope will not be waved arbitrarily.
