Summary of the invention
Technical problem to be solved in the utility model provide a kind of quick and easy for installation, safe and reliable can effectively increase work efficiency entirely be used for ultra-high-tension power transmission line tangent tower live line working tower end load jig.
The utility model adopts following technical scheme:
The utility model comprises jig, jig leading screw, can drive leading screw lowering or hoisting gear that the jig leading screw moves up and down and the insulated hanger bar that is arranged on jig leading screw lower end.
Jig described in the utility model both sides are provided with the jig wing plate, and the jig wing plate is provided with the reinforcement gusset.
The width of jig wing plate described in the utility model is 40-60mm, and the optimum width of jig wing plate is 45-59mm.
The beneficial effects of the utility model are: use the transmission of a complete set of load instrument of the utility model once to finish, avoid repeating work, reduce workload, reduce manpower, time input, increase work efficiency, the utility model method of operation is easy, and practical function is obvious, can be applied to 110kV～500kV transmission line tangent tower live line working work.
The utility model is particularly useful for the contest of live line working technical ability.
Use the simplification of the utility model operating procedure, can reduce the probability that the hazard events such as falling object from high altitude of instrument in transmittance process takes place, guarantee safety.Personnel need not be stretched in body part (hand) cross-arm master material below on the tower.The person and shielding clothing can the short circuit electrified body and earth electrode between the air gap.Guarantee charging equipment and personal safety, improve the job safety level.
Description of drawings
Accompanying drawing is the utility model structural representation.
In the accompanying drawings: 1 jig, 2 jig leading screws, 3 jig wing plates, 4 are strengthened gusset, 5 leading screw lowering or hoisting gears, 6 iron tower main materials, 7 insulated hanger bars, 8 insulator strings, 9 leads, 10 hooks, 11 operating grips.
