Abstract
The utility model relates to the field of 10 KV power distribution network live working, and particularly relates to a self-lifting type insulation cross arm. The self-lifting type insulation cross arm is characterized by comprising a cross arm main body, a metal handle holder, a tensile soft belt and insulation hooks. Two ends of an arc-shaped metal handle holder upwarp and are disposed on the top of the cross arm; one end of the tensile soft belt is connected with the metal handle holder; the other end of the metal handle holder is provided with a tightening handle; 1-3 of the insulation hooks are disposed below the cross arm main body; each insulation hooks is disposed at the lower end of an insulation rope; and the upper end of each insulation rope is wound around a self-locking pin shaft disposed on the cross arm main body. Compared with conventional insulation cross arms, the self-lifting type insulation cross arm has the beneficial effects that a structure is simple; and the self-lifting type insulation cross arm can finish installation of a pole top switch in cooperation with an insulation arm vehicle, reduce participation of crane vehicles, reduce operation difficulties and labor intensity of additionally installing the pole top switch on a strain section of a linear rod, without deducting lower end load of operation points, reduce the number of operating personnel participating in and shorten whole operation time.
Description
Technical field
The utility model relates to 10kV live working of distribution network field, relates in particular to a kind of from hanging insulator crossarm.
Background technology
At present, the live line working of power distribution network is the main direction of studying of power distribution network operation technique, and hot line maintenance is the Main Means that solves power distribution network uninterrupted operation.Such as changing at straight line pole in the operation that strain section installs on-pole switch additional, be mainly to utilize equipment to turn on-load to reach the object of uninterrupted operation, but because operation participant is many, also need truck crane compounding practice, so length consuming time, difficulty is large, labour intensity is large, is unfavorable for promoting the use of.
Summary of the invention
The purpose of this utility model is to provide a kind of from hanging insulator crossarm, simple in structure, can assist and realize on-load operation, reduce straight line pole and change task difficulty and the labour intensity that strain section installs on-pole switch additional, shorten consuming timely, reach that few people carries out, the object of uninterrupted operation.
To achieve these goals, the utility model is by the following technical solutions:
From hanging insulator crossarm, comprise that cross-arm main body, metal are holder, the soft band of tension and insulation suspension hook, curved metal upwarps holder two ends the top of being located at cross-arm main body, one end of the soft band of tension is connected one end of holder with metal, metal is provided with the other end of holder to tighten up handle, and metal is provided with metal stabilizing bracket holder; Described cross-arm main body below is provided with 1～3 insulation suspension hook, and insulation suspension hook is located at the lower end of insulating cord, and the upper end of insulating cord is wrapped on the self-locking bearing pin of being located in cross-arm main body, between one end of self-locking bearing pin and cross-arm main body, is provided with location jump ring.
Described cross-arm main body is insulation material, and its length is 1700～1800mm.
Compared with prior art, the beneficial effects of the utility model are:
Simple in structure, can coordinated insulation bucket arm vehicle complete the installation of on-pole switch, reduced the participation of lifting vehicle, reduce straight line pole and change task difficulty and the labour intensity that strain section installs on-pole switch additional, without the lower end load of reduction process point, reduce the number that participates in operating personnel, shortened overall operation duration.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 1, that the utility model is from hanging insulator crossarm example structure schematic diagram, comprise that cross-arm main body 1, metal be with 3 and insulation suspension hook 4 holder 2, tension are soft, curved metal upwarps holder 2 two ends the top of being located at cross-arm main body 1, the soft one end with 3 of tension is connected one end of holder 2 with metal, metal is provided with the other end of holder 2 to tighten up handle 5, and metal is provided with criss-cross metal stabilizing bracket 6 holder 2; Cross-arm main body 1 below is provided with 3 insulation suspension hooks 4, insulation suspension hook 4 is located at the lower end of insulating cord 7, the upper end of insulating cord 7 is wrapped on the self-locking bearing pin 8 of being located in cross-arm main body, between one end of self-locking bearing pin and cross-arm main body, be provided with location jump ring 9, the long 500mm of insulating cord 7, has draw-in groove on 8 of self-locking bearing pins, location jump ring 9 is stuck in draw-in groove can prevent that self-locking bearing pin from rotating, in the time will putting down insulation suspension hook 4, as long as pull out location jump ring 9 from draw-in groove, self-locking bearing pin 8 can rotate and put down insulation suspension hook.Cross-arm main body 1 is insulation material, and its length is 1780mm.
Operating personnel is when installing from hanging insulator crossarm, only the soft band of tension need be pierced into and tightens up handle, then operation is tightened up handle and is tightened up the soft band of tension, make to link together from hanging insulator crossarm and electric pole, the method is time saving and energy saving, can significantly reduce the labour intensity of operating personnel when installing insulating cross-arm, thisly from hanging insulator crossarm, is easy to install, simple to operate, be applicable to distribution network live line work.
