Embodiment Construction
[0025] see Figure 1 ~ Figure 2 , the electric lifting high-altitude grounding device of the present invention includes a grounding clamping mechanism and a lifting device 14;
[0026] The ground clamping mechanism includes a base 1, the top of the base 1 is provided with a wiring pile head 2 and a clamping arm, and the wiring pile head 2 is connected with a grounding wire 3; the clamping arm has two, respectively It is the first clamp arm 4 and the second clamp arm 5; the first clamp arm 4 and the second clamp arm 5 are hinged with the top of the base 1 through the hinge 6; the first clamp arm 4 and the A mobile chuck 7 is sleeved on the second clamp arm 5. When the mobile chuck 7 moves up, the distance between the two clamp arms decreases to realize the clamping action. When the mobile chuck 7 moves down, the two clamps The distance between the arms is increased to realize the release action; the inside of the base 1 is provided with a threaded hole, and a rotating shaft 8 ...

The invention discloses an electric 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 four-claw clamp, a rotating shaft, a high-definition camera, a multi-section lifting pole, a tripod, a controller, and a power interface. The 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 an electric 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 ...
