Summary of the invention
In view of this, the object of the invention is to provide a kind of different geographical environments that are applicable to, more changing jobs can be light, electric wire line lifter flexibly.
For solving above technical problem; Technical scheme provided by the invention is to provide live line working to use the ultra-high-tension power transmission line line lifter, the hanging wire mechanism that has wire grip, is connected the insulation arm-tie of wire grip lower end and connects insulation arm-tie lower end; It is characterized in that; Also comprise a yoke plate jig that can be installed on the insulator string triangle yoke plate, have the inner concave that fits with the triangle yoke plate on the said yoke plate jig, the hypotenuse of inner concave left end edge and triangle yoke plate fits; The inner concave right-hand member is provided with first connecting hole that can be connected with the perforate on the triangle yoke plate, and the left end of yoke plate jig is provided with second connecting hole that is connected with the wire grip upper end.
Said insulation arm-tie is telescopic insulation arm-tie.
Said hanging wire mechanism is hook structure or snap ring structure.
Compared with prior art, the present invention has following advantage:
1, both had been applicable to that insulator string hanging point both sides circuit was horizontal arrangement, also is applicable to that hanging point both sides circuit is replacing and the maintenance of insulator string under the charged situation of circuit of non-horizontal arrangement.Yoke plate jig of the present invention directly is connected on the double insulator string triangle yoke plate; No matter whether the hanging point both sides overhead line structures discrepancy in elevation is horizontal arrangement; All not too need the long process of tightening up of wire grip (like screw mandrel), so as long as operating personnel adjust lower stretching wire device process a little and all can make the hanging wire mechanism power transmission line of slinging on the tower, and then make insulator string loose; Easy to replace and maintain, guaranteed the safe distance of operating personnel and electrified body.
2, the present invention installs easily, and steadily.On the yoke plate jig of the present invention the inner concave edge with can with the corresponding connecting hole of existing perforate (being eyelet) on the triangle yoke plate, so the present invention be easy to the couplet connect on the triangle yoke plate; Have, because the needed wire grip process of tightening up is lacked again, the triangle yoke plate can not produce dancing in the circuit tightening process like this, has avoided the long generation that causes the single-line to ground fault accident of wire grip metal section and part yet again.
3, the difficulty of using the present invention obviously to reduce labour intensity and more to change jobs.Because install easily, take-up is steady, only need a people just can change insulator string light, neatly, so high efficiency and safety.
4, the present invention is simple and reasonable for structure, and application prospect is good.
