Abstract
The utility model relates to the technical field of maintenance of high-voltage power transmission lines in the electric power industry, specifically to an insulation protective umbrella. When doing middle phase live-line work on common-tower parallel power transmission lines, ground potential work personnel may be threatened by upper phase live conductors. The technical scheme of the utility model is that the top end of an insulated rod is provided with an insulated hanging hook; the lower segment of the rod body of the insulated rod is sequentially fixed with an upper limiting plate, a supporting frame bar fixing plate, and a lower limiting plate from top to bottom; multiple supporting frame bars are hinged and connected around the supporting frame bar fixing plate in a radial manner; an insulated umbrella cover is mounted on the supporting frame bars; the two ends of each upper limiting rope are fixed on the upper limiting plate and the corresponding supporting frame bar; and each lower limiting rope penetrates through via holes on the lower limiting plate, and the two ends of each lower limiting rope are fixed on the corresponding supporting frame bar and a pulling rope. The insulation protective umbrella is made of a high-strength insulating material and provides a safe working space for construction personnel doing the live-line work on a middle phase cross arm of the common-tower parallel power transmission lines.
Description
Technical field
The utility model relates to power industry ultra-high-tension power transmission line maintenance technology field, a kind of protection tool while belonging to high voltage transmission line live work, specifically a kind of insulation protection umbrella.
Background technology
220kV is with shaft tower frame transmission line, and the cross-arm length that is arranged in the shaft tower upper strata is less than or equal to phase cross-arm length.During underway phase live line working, the earth potential staff on middle phase cross-arm can be subject to the threat of phase live wire.The staff slightly has carelessness, as actions such as straight waist stretch, stretches out one's hand, between human body and upper phase conductor, can't guarantee enough safe distances, now very likely cause that live wire discharges to the operating personnel, cause the overhead transmission line tripping operation, the safety that even threatens operating personnel's person and electrical network when serious.Owing to there is no special-purpose insulation protection instrument protection, usually take on shaft tower to establish special messenger's monitoring, and constantly remind staff's method to be protected at present, during work, need many people to coordinate, and danger coefficient is higher, has potential safety hazard, efficiency of construction is lower.
Summary of the invention
The purpose of this utility model is to provide a kind of insulation protection umbrella, to overcome deficiency of the prior art, is convenient to the work in every of carrying out on the tower bar.
The technical solution of the utility model is: insulating bar, insulating hanger, upper limit plate, lower limiting board, support hack lever fixed head, upper limit rope, lower limit rope, stay cord, support hack lever, insulation umbrella cover, consist of;
Insulating hanger is equipped with on the top of insulating bar; The body of rod hypomere of insulating bar from up to down is fixed with successively the upper limit plate, supports hack lever fixed head, lower limiting board, and many support hack levers are radial and are articulated and connected around support hack lever fixed head; Support on hack lever the insulation umbrella cover is installed;
Have through hole around insulating bar on upper limit plate and lower limiting board; Many upper limit rope two ends are fixed on the through hole of upper limit panel area and support the middle part of hack lever; Each lower limit rope is through the through hole around lower limiting board, and two ends are fixed on the middle part and stay cord of supporting hack lever;
Further, the body of rod of described insulating bar is the dismantled and assembled structure of more piece or the multi-joint telescoping body of rod.
Further, the insulating hanger of described insulating bar upper end to the distance that supports the hack lever fixed head is not less than 2.1 meters.
Further, described bracing frame pole length is not less than 1.4 meters.
The utility model has the advantages that: simple in structure, easy for installation, the employing high-strength insulating material is made, solved while in same shaft tower frame transmission line, on the phase cross-arm, carrying out live line working, the problem that earth potential working personnel on middle phase cross-arm are threatened by the phase live wire, insulation net umbrella cover with below the working space of a safety of formation between cross arm of tower, guarantee workmen's safety work.
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is elaborated.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The schematic diagram that Fig. 2 is the utility model insulation net umbrella cover;
Fig. 3 is use state diagram of the present utility model.
Embodiment
In figure: 1, insulating bar, 2, insulating hanger, 3, the upper limit plate, 4, the upper limit rope, 5, the insulation umbrella cover, 6, the lower limit rope, 7, lower limiting board, 8, stay cord, 9, support the hack lever fixed head, 10, support hack lever.
Embodiment
From Fig. 1～Fig. 3, the utility model is comprised of insulating bar 1, insulating hanger 2, upper limit plate 3, lower limiting board 7, support hack lever fixed head 9, upper limit rope 4, lower limit rope 6, stay cord 8, support hack lever 10, insulation umbrella cover 5;
Have through hole around insulating bar 1 on upper limit plate 3 and lower limiting board 7, many upper limit rope 4 two ends are separately fixed on the through hole around upper limit plate 3 and support the middle part of hack lever 10; Each lower limit rope 6 is through the through hole around lower limiting board 7, and two ends are separately fixed on the middle part and stay cord 8 of supporting hack lever 10.
During use; first insulating bar 1 is stretched; recycling insulating hanger 2 hangs over insulated umbrella on upper phase conductor; pull stay cord 8; drive lower limit rope 6 and make umbrella cover; then the end of stay cord 8 is banded on the members such as angle steel of shaft tower, now goes up between phase conductor and umbrella cover the safe distance of at least 2.1 meters is arranged, form the working space of a safety between insulation protection umbrella umbrella cover below and cross-arm.After end-of-job, untie stay cord 8, remove the insulation protection umbrella.
Finally should be noted that: above embodiment is for illustrating that the technical solution of the utility model is not intended to limit; the those skilled in the art modifies to execution mode or the part technical characterictic is equal to replacement; and do not break away from the essence of technical solutions of the utility model, within all should being encompassed in the utility model scope required for protection.
