Pneumatic lifting high-altitude grounding device

Abstract

The invention discloses a pneumatic lifting high-altitude grounding device which comprises a grounding clamping mechanism and a lifting device. The grounding clamping mechanism comprises a base, the top end of the base is provided with a wiring pile head clamping arms, and the wiring pile head is connected with a grounding wire; the clamping arms are sleeved with a movable chuck, a clamping action is achieved when the movable chuck moves upwards, and a releasing action is achieved when the movable chuck moves downwards; the interior of the base is provided with a threaded hole, a rotation shaft penetrates through the threaded hole, and the rotation shaft is in threaded connection with the threaded hole; the upper end of the rotation shaft is fixedly connected with the movable chuck; the lower end of the rotation shaft is fixedly provided with a clamping plate. The lifting device comprises a base, an air source connector, a four-claw clamp, a revolving shaft, a high-definition camera, multiple lifting rods and a tripod. The pneumatic lifting high-altitude grounding device has the advantages that maintenance personnel can conveniently and quickly perform grounding, the structure is simple, the grounding clamping and releasing actions are simple and reliable, and the grounding operation efficiency is high.

Description

technical field [0001] The invention relates to a pneumatic lifting high-altitude grounding device. 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 maintenance ...
