Overhauling tool for live working of 750kV transmission line

Abstract

The invention relates to an overhauling tool for transmission line working at heights, in particular to an overhauling tool for high-altitude live working of a 750kV transmission line. The overhauling tool comprises a base platform, two insulator clamping supports and a hoisting support. The lower portions of the two insulator clamping supports are arranged at the left end and the right end of the base platform, arc-shaped clamping supports are arranged at the upper ends of the insulator clamping supports, the upper ends of the arc-shaped clamping supports are connected to the left end and the right end of the hoisting support through connecting arms, and a hoisting hole is arranged at the position of the center of the hoisting support. The base platform, the insulator clamping supports, the hoisting support and the connecting arms are made of insulating epoxy resin, the base platform is in riveted connection with the insulator clamping supports through insulating epoxy resin rivets, and the connecting arms are in riveted connection with the insulator clamping supports and the hoisting support through insulating epoxy resin rivets. The overhauling tool is good in insulation performance, simple to install and convenient to process, an occupied space is small in operation, overhauling efficiency is high, workers can carry a clamp in a standing posture, the force-applying radius can be reduced when the workers carry the clamp, and safety in operation is guaranteed.

Description

technical field [0001] The invention relates to a maintenance tool for high-altitude operation of power transmission lines, in particular to a maintenance tool suitable for high-altitude live working of 750kV power transmission lines. Background technique [0002] The existing transmission line replaces the tension-resistant single-piece insulator operation method, and the operator adopts a squatting or sitting position to work, while the 750 kV transmission line replaces the tension-resistant single-piece insulator operation, the fixture weighs 54 kg, and the operator adopts a squatting or sitting position. It is very difficult to lift the fixture in a sitting position; if it is in the process of live work, due to the limitation of the protective gap distance, the diameter of the insulator and the distance between the insulator strings, the operator's arm cannot reach the fixture, even if he grasps The jig cannot be lifted up by force. Not only is it difficult for operator...

[0002] The existing transmission line replaces the tension-resistant single-piece insulator operation method, and the operator adopts a squatting or sitting position to work, while the 750 kV transmission line replaces the tension-resistant single-piece insulator operation, the fixture weighs 54 kg, and the operator adopts a squatting or sitting position. It is very difficult to lift the fixture in a sitting position; if it is in the process of live work, due to the limitation of the protective gap distance, the diameter of the insulator and the distance between the insulator strings, the operator's arm cannot reach the fixture, even if he grasps The jig cannot be lifted up by force

Not only is it difficult for the operators to bear the high physical consumption, but it will also greatly reduce the safety of the operation or fail to complete the maintenance work
