High-altitude grounding device for hydraulic lift

Abstract

The invention discloses a hydraulic lifting high-altitude grounding device, which includes a grounding clamping mechanism and a lifting device; the grounding clamping mechanism includes a base, and the top of the base is provided with a wiring pile head and a clamping arm, and the wiring pile head is connected with a grounding line; the upper sleeve of the clamp arm is equipped with a movable chuck, which realizes the clamping action when the movable chuck moves up, and realizes the release action when the movable chuck moves down; the inside of the base is set in a threaded hole, and the rotating shaft passes through the threaded hole , the rotating shaft and the threaded hole are threaded; the upper end of the rotating shaft is fixedly connected with the movable chuck; the lower end of the rotating shaft is fixed with a clamping plate. The lifting device includes a base, a high-pressure oil interface, a four-claw clamp, a rotating shaft, a high-definition camera, a multi-section lifting rod, and a tripod. The hydraulic lifting high-altitude grounding device of the present invention has the advantages of being convenient for maintenance personnel to quickly ground, simple structure, simple and reliable grounding clamping and releasing actions, and high grounding operation efficiency.

Description

technical field [0001] The invention relates to a high-altitude grounding device for hydraulic lifting. Background technique [0002] Grounding (earthing) refers to the neutral point of the power system and electrical devices, the exposed conductive parts of electrical equipment and the conductive parts outside the device are connected to the earth through conductors. In the power system, the ground wire is an important tool to ensure the safety of the staff when the voltage appears unexpectedly on the equipment and lines that have been powered off. The function of the grounding wire is to prevent the human body from being harmed by the sudden call of the equipment or the induced voltage generated by the adjacent high-voltage live equipment when the high-voltage equipment is powered off for maintenance or other work, and at the same time discharge the residual charge of the power-off equipment. [0003] Installing and removing temporary ground wires is an important maintena...
