A high-voltage line maintenance device of chain-drive lifting type substation system

Abstract

A high-voltage line maintenance device of chain-driven lifting type substation system comprises a traveling frame, a power mechanism, a chain lifting mechanism and a telescopic rod hitching mechanism.The high-voltage line maintenance device comprises a traveling frame, a power mechanism, a chain lifting mechanism and a telescopic rod hitching mechanism. The traveling car frame plays a supportingrole, the chain lifting mechanism is located in front of the traveling car frame, the power mechanism is installed in the middle of the car frame, and the power is transmitted to the chain transmission mechanism through the bevel gear after the worm gear reducer reduces the speed. The worm gear reducer is used to realize the self-locking function of the lifting device, and a limited position frameis set to limit the lifting device. The high-voltage line maintenance device of chain-driven lifting type substation system replaces the work of directly connecting the earthing wire with the hand-held telescopic rod, thus avoiding the direct contact between the worker and the earthing device and ensuring the safety of the worker.

Description

technical field [0001] The invention relates to the technical field of maintenance tools for high-voltage lines in substations, in particular to a maintenance device for high-voltage lines in a chain-driven lifting type substation system. Background technique [0002] At present, during the AC transformer up-flow experiment in substations or the maintenance of high-voltage lines in substations, it is often necessary to perform grounding operations on transmission lines. Most of the current grounding work involves workers holding telescopic rods to ground high-voltage lines. Due to the high height of high-voltage lines from the ground , so this kind of operation is labor-intensive, and there is a great potential safety hazard. When the maintenance workers leave the telescopic rod, the telescopic rod and the power line are also relatively easy to separate, which will cause serious damage to the life safety of workers who are undergoing circuit maintenance. Greatly threatening....
