Supergrid 500kV transforming plant primary equipment complex structure, electric trial work is carried out wiring to the 500kV primary equipment and generally will be used overhead vehicle in doing, and wastes time and energy.Insulating rod can be delivered to test that the pile crown place not only saves the operating time with last pile crown agrees with and play fixation on the equipment of eminence with line, also saved the manpower and materials of dispatching overhead vehicle, meets the principle of efficient energy-saving under the market economic system.
The last pile crown structure of field apparatus is various; The situation of the line bank that on-the-spot electricity studies that common last pile crown structure in the industry is that last pile crown is fluted, Luo Dong and last pile crown are the different shape that is directed upwardly; Existing insulating rod hook is generally hook-type, is only applicable to that pile crown is fluted, the situation of Luo Dong.Be the situation of the line bank of the different shape that is directed upwardly for last pile crown, can't fix do not have suitable link device with existing insulating rod joint wiring.
The utility model content
The purpose of the utility model is to provide a kind of modified model insulating rod hook, to solve the problems of the technologies described above.
The technical problem that the utility model solved can adopt following technical scheme to realize:
Modified model insulating rod hook comprises an insulation barred body, it is characterized in that, the end of said insulation barred body is provided with the circular collar that removably connects, and the said collar comprises a metallic sheath ring portion and the spring housing ring portion that is fixedly connected with said metallic sheath ring portion;
The Lower Half of the said collar is the metallic sheath ring portion, and the first half of the said collar is the spring housing ring portion.
The inside of said spring housing ring portion is provided with the flexible draw cord that is used to tighten up the spring housing ring portion; One end of said stay cord is fixedly connected with an end of said spring housing ring portion, and the other end of said stay cord extend out to the bottom of said insulation barred body from the other end of said spring housing ring portion.The stay cord that said stay cord adopts insulating material to process.
Said spring housing ring portion is connected with said metallic sheath ring portion through the mode of welding.
The metallic sheath ring portion that said metallic sheath ring portion adopts solid metal pipe to process, the metallic sheath ring portion that also can adopt hollow metal tube to process.The preferred metallic sheath ring portion that adopts hollow metal tube to process can be saved metal material, and is simultaneously more light and handy.
Said metallic sheath ring portion adopts copper metallic sheath ring portion, also can be metallic sheath ring portion aluminium matter or aluminium alloy.The preferred metallic sheath ring portion that adopts aluminium alloy to process.The corrosion resistance of aluminium alloy is good, and hardness and intensity all meet the demands simultaneously.
The spring housing ring portion that said spring housing ring portion adopts stage clip to process, the spring housing ring portion that said spring housing ring portion adopts stainless steel wire to process.
The insulation barred body that said insulation barred body adopts epoxy resin to process.
When the utility model uses, the collar is hung over pile crown, tighten up stay cord downwards, the spring housing ring portion is shunk, and the area that pile crown is gone up in the spring coil contact increases, and has guaranteed electric conductivity; Behind the complete operation, the stay cord that tightens up is unclamped, the spring housing ring portion returns to shape originally automatically, conveniently it is taken off from last pile crown.
Beneficial effect: owing to adopt technique scheme, the utility model is applicable to that pile crown is the situation of the line bank of the different shape that is directed upwardly, helps the operation at scene.
