Abstract
The utility model relates to a working tool used for overhead lines, in particular to an insulation displacement restrictor. In the structure key point, the working tool comprises an insulation isolation board, a lug pole and a hook, wherein, the insulation isolation board is hung and supported on the lower end of the lug pole, the upper end of the lug pole is connected with the hook, and the insulation isolation board, the lug pole and the hook are all made by insulating materials. Compared with the prior art, the working tool of the utility model has the advantages of effectively limiting working space, limiting operating personnel to operate in a prescriptive range, guaranteeing a safety distance with a charged body, and providing an effective insulation safety warning for personnel of live working when the activity space of the live working on a tower is limited and narrow.
Description
Technical field
The utility model relates to a kind of power tool that is used for overhead transmission line, particularly a kind of insulation stop.
Background technology
In the high-tension line of many wiring on the same tower, lead adopts vertical arrangement, and distance between last phase-middle phase-following phase cross-arm and the distance that goes up between phase conductor-middle phase cross-arm or the middle phase conductor-following phase cross-arm are very compact.Cause the actual activity space of live line working personnel on shaft tower extremely limited, do not note slightly breaking through safe distance.For example, in the 110kV of two Hui Tongta circuit, lead adopts vertical arrangement, and last phase-middle phase-following phase cross-arm is at a distance of 3500mm, and the insulator assembled height is 2000mm, last phase conductor-middle phase cross-arm or middle phase conductor-only remaining 1500mm of following phase cross-arm distance.According to live line working regulation in " State Grid Corporation of China's electric power safety working regulation " (power circuit part), " person and the safe distance electric pressure of electrified body must not be less than 1.0 meters for 110kV person during live line working ", operating personnel's actual activity space just has only 500mm, quite narrow, according to the routine work method, be difficult to guarantee normally carrying out of live line working.
The utility model content
The purpose of this utility model is to overcome weak point of the prior art, provides a kind of under limited, the narrow situation of live line working activity space on the shaft tower, and the insulation stop of insulation safety warning is provided for the live line working personnel.
The purpose of this utility model realizes by following approach.
The insulation stop, its structural feature is: it comprises insulation division board, peg and hook, and the insulation division board is hung and is propped up in the lower end of peg, and the upper end of peg is connected with hook, and insulation division board, peg and hook are made by insulating material.
During use, the insulation stop is hung on the lead of live line working personnel top, can effectively limit working space, restriction the operating personnel operate within the limits prescribed, guarantees to keep a safe distance with electrified body.
Those skilled in the art in conjunction with the shaft tower actual conditions, can conveniently calculate the safe altitude at least of whole insulation stop according to national live line working safety standard.
The purpose of this utility model can also realize by following approach.
As preferably, the diameter of insulation division board is more preferably greater than the width of cross-arm.
The insulation division board can be a Construction integration, and as preferably, the insulation division board is preferably by two hinged forming.
Be convenient for carrying also convenient the use like this.
Also comprise a kind of closing device, be installed on the hook, be made up of fork and torsion spring that fork is hinged on the hook opening part and across on the hook opening, torsion spring one end is supported on the hook, the other end is supported on the fork.
During so downward extension insulation stop, after lead flicked fork and enters hook, the elastic force that torsion spring produces was repositioned to fork across on the hook opening, thus closed hook opening.Can prevent that like this operating personnel's head in operation process from may contact the insulation division board, the division board that causes insulating comes off.
In sum, the utility model has following advantage compared to existing technology: can effectively limit working space, restriction the operating personnel operate within the limits prescribed, guarantee to keep a safe distance with electrified body, under limited, the narrow situation of live line working activity space on the shaft tower, for the live line working personnel provide a kind of effective insulation safety warning.
Description of drawings
Accompanying drawing 1 is the structural representation front view of insulation stop embodiment described in the utility model,
Accompanying drawing 2 is structural representation left views of insulation stop embodiment described in the utility model;
Accompanying drawing 3 is schematic diagrames that insulation stop two insulation boards described in the utility model are packed up;
Accompanying drawing 4 is structural representation left views of accompanying drawing 3.
Below in conjunction with embodiment the present invention is described further.
Specific embodiment
With reference to accompanying drawing 1: the insulation stop, comprise insulation division board 1, peg 2, hook 3 and closing device 4, insulation division board 1 is hung in the lower end of peg 2, and the upper end of peg 2 is connected with hook 3, and division board 1, peg 2 and link up with 3 and make by insulating material insulate.
Wherein peg 2 can be a kind of epoxy tube, and insulation division board 1 can be a kind of circle, square, or any suitable working geometric figure.Optimal way is that this insulation division board 1 is a kind of circular slab preferably, and is articulated and connected by two semicircle insulation boards and forms, and its diameter is greater than the width of cross-arm.The top of insulation division board 1 is close to and is connected with a limiting plate gusset 5, this is because the area of insulation division board is bigger, support for reinforcing the insulation division board, so increase this gusset 5, this gusset 5 is an oblong shape, also can be a rectangle, its width be significantly smaller than the diameter of insulation division board, and length can be isolated identical or close with insulation.
Be the convenient structure of the present utility model of understanding, the left view of above-mentioned accompanying drawing 1 also is provided in the Figure of description, and front view and the left view of insulation division board when closed.
It is same as the prior art that the utility model is not stated part.
