The 500kV circuit overwhelming majority is overhead transmission line, is vulnerable to the impact of the environmental factors such as wind, rain, ice and snow in running, causes appearance displacement, the even fatigue damages such as conductor spacer.Particularly in recent years, affected by the bad weathers such as cool winds, sleet and snow ice, powerline ice-covering has on a large scale occurred repeatedly and has waved situation in electrical network, wherein the 500kV transmission line galloping has caused line tripping and the steel tower cross-arm is impaired, bolt falling, wire jumper drainage thread destruction, insulator and the faults such as conductor spacer is impaired, stockbridge damper slippage, has caused considerable influence to the normal operation of electrical network.
In order to process in time the ubiquitous displacement of rod of 500kV line segregation and the damage problem of repairing, line attendant need to reach the shaft tower position along rugged road walking, climb again the high tower more than 20 meters, proceed to setting at average span cabling in the line shelves more than 500 meters, physical demands to line attendant is high, and traditional conductor spacer spanner is from great, use inconvenience, make the line attendant operating efficiency not high, at health under extremely tired state, the accident that very easily makes it meet accident, cause economic loss and casualties, be unfavorable for completing in the short period of time the maintenance work to the 500kV circuit.
Summary of the invention
Given this, the utility model purpose is to provide a kind of lightweight, easy to operate conductor spacer special spanner.
For solving above technical problem, the technical scheme that the utility model provides is that a kind of conductor spacer special spanner is provided, comprise pedestal, this pedestal is that rectangular-shaped ,Qi center is provided with screw, the two ends, left and right are provided with the suspension hook mounting groove, pin hole and this suspension hook mounting groove square crossing; Be rotatably connected to suspension hook by pin in each suspension hook mounting groove, be connected with screw rod in screw, the upper/lower terminal of screw rod all is set to the polygon main body, on the polygon cylinder of lower end, also is provided with rivet hole, the screw rod lower end is arranged with bearing and pad, and to bearing and pad, carries out spacing by rivet.
Further, described suspension hook is a L shaped plate part, and its upper end is provided with the pin connecting hole, and lower end is provided with hook; The hook of two suspension hooks is all towards screw rod.
Further, described pin one end is set to major part, and the other end is provided with annular slot, and jump ring is fastened in draw-in groove.
Preferably, described bearing and pad endoporus are polygon.
Further, also comprise handle, an end of this handle is provided with the polygon endoporus that the polygon post with the screw rod upper end is complementary.
Preferably, on described handle, decorations are carved with anti-slip veins.
Compared with prior art, a technical scheme in technique scheme has following advantage:
1, overall weight of the present utility model is light than traditional spanner, size is little, be easy to carry, easy operating, flexibility be high, practical, greatly shortened the reparation conductor spacer Job Operations time, effectively improved operating efficiency, reduce operating personnel's labour intensity, thereby ensured the safety of operating personnel and equipment.
2, the utility model has been used bearing, and during use, the outer ring of this bearing is attached to the position, aperture of conductor spacer wire clamp.During rotating screw bolt, screw rod more easily is rotated, and can not be stuck in the hole of conductor spacer wire clamp, also just is difficult for causing spanner self to damage, and more can not cause damage to the wire clamp of conductor spacer.
The accompanying drawing explanation
Fig. 1 is the front view of the utility model one preferred embodiment.
Fig. 2 is A-A cutaway view in Fig. 1.
Fig. 3 is B-B cutaway view in Fig. 1.
Fig. 4 is the front view of the handle in the utility model one preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing and a specific embodiment, describe.
Referring to Fig. 1 to Fig. 4.The described a kind of conductor spacer special spanner of the present embodiment, consist of following part: pedestal 1, suspension hook 2, pin 3, screw rod 4, bearing 5, pad 6, rivet 7, handle 8.Pedestal 1, for rectangular-shaped or be substantially rectangular-shapedly, for the purpose of attractive in appearance, optionally carries out the corners processing to individual limit.The center of pedestal 1 is provided with screw, and the two ends, left and right are provided with the suspension hook mounting groove.Pin hole and the square crossing of suspension hook mounting groove.Be rotatably connected to suspension hook 2 by pin 3 in each suspension hook mounting groove.Pin 3 one ends are set to major part, and the other end is provided with annular slot, and jump ring 31 is fastened in draw-in groove.Suspension hook 2 is a L shaped plate part, and its upper end is provided with the pin connecting hole, and lower end is provided with hook, and the hook of two suspension hooks is all towards screw rod 4.Screw rod 4 spins with screw, and the upper/lower terminal of screw rod 4 all is set to the polygon main body, and what in accompanying drawing, look out is the situation of cuboid.Also be provided with rivet hole 41 on the lower end quadrangle cylinder of screw rod 4, the screw rod lower end is arranged with bearing 5 and pad 6, and the endoporus of bearing 5 and pad 6 is square hole, and when using spanner, bearing 5 can be with respect to bolt rotary.Rivet 7 is plugged in rivet hole 41, and its Main Function is that restriction bearing 5 and pad 6 move up and down.
