Abstract

The utility model relates to an assistant tool in the power industry, in particular to a suspension bracket for replacing insulators. As the existing hoisting hardware fittings can not be fixed on a cathead tower, the live replacement of an insulator on a 500kV cathead tower can not be realized. The suspension bracket consists of hoisting hardware fittings, an insulating pull rod, a base and a hoisting hardware fittings bracket; wherein, the base and the hoisting hardware fittings bracket are connected by thread; the hoisting hardware fittings are put in a hoisting hardware fittings fixing hole on the hoisting hardware fittings bracket; by using the suspension bracket for replacing insulators to fix the hoisting hardware fittings on the cathead tower, the aim of lively replacing the insulator of the cathead tower in a high-voltage power transmission line is achieved. The suspension bracket has high stability, low manufacturing cost, easy and rapid installation in the working process, shortens the operating time on the tower, improves the efficiency of workers, lowers the labor intensity, reduces the power-off quantity of the power transmission line, and improves the reliability of electricity supply and economic benefit of the power transmission line.

Description

Change insulator arrangement
Technical field
The utility model relates to power industry maintenance, repair cable machinery technical field, specifically a kind of replacing insulator arrangement.
Background technology
At present, change in the work of ultra-high-tension power transmission line straight line insulator string in live line working, can't be fixed on the cat head tower owing to promote gold utensil, causing can not the charged for replacement insulator on 500kV cat head tower.When changing insulator, need the circuit outage to construct, influence transmission line and normally move, cause the certain economic loss, and operating efficiency is lower.
Summary of the invention
The purpose of this utility model provides a kind of replacing insulator arrangement, can realize live line working replacing high-voltage transmission line insulator.The technical solution of the utility model is: form by promoting gold utensil, insulated tension pole, base and lifting gold utensil support; Promoting gold utensil is made up of leading screw, jig, leading screw adjusting nut, ratchet spanner, there is support column the jig both sides, there is through hole at the middle part, leading screw penetrates the through hole of jig, the leading screw adjusting nut is housed on the leading screw on jig top, be fixed with ratchet spanner on the leading screw adjusting nut, pull ratchet spanner rotating threaded shaft adjusting nut leading screw is axially moved in jig; The support fixed bit that a base fixing hole and a projection are arranged on the base; Promoting gold utensil support top has the gold utensil of lifting fixing hole, and respectively there is brace groove both sides, and locking device is equipped with in the side of brace groove; Base passes connecting hole with lifting gold utensil support by bolt and is connected.
When carrying out live line working replacing ultra-high-tension power transmission line straight line insulator work, utilize the bolt at place, working point on the cat head tower to pass base fixing hole on the base, to change insulator arrangement is fixed on the iron tower main material, promote gold utensil and put into the lifting gold utensil fixing hole that promotes on the gold utensil support, support column on the jig that promotes gold utensil is snapped in the brace groove that promotes the gold utensil support, close-lock device and with screw locking prevents to promote gold utensil and deviates from from promoting in the gold utensil fixing hole accident; The insulated tension pole upper end is by being bolted to the leading screw lower end that promotes gold utensil, pull ratchet spanner rotational lead screw adjusting nut, adjust the height of leading screw, make the lower end and the high voltage electricity transmission conductive wire that are fixed on the insulated tension pole on the leading screw contour, and high voltage electricity transmission conductive wire is hung over the insulated tension pole lower end by thread hook; Pull ratchet spanner rotational lead screw adjusting nut, leading screw is upwards axially moved in jig, leading screw drive insulated tension pole moves upward transmission pressure is sling, then the load transfer of insulator string can begin live line working and change ultra-high-tension power transmission line straight line insulator to promoting on gold utensil and the insulated tension pole.
The utility model stability in the course of the work is high, and low cost of manufacture is quick and easy for installation, has improved operating efficiency, has reduced labour intensity, and the circuit outage has been avoided in construction, solved on 500kV cat head tower can not the charged for replacement insulator a difficult problem.
