Embodiment Construction

[0022] see Figure 1 ~ Figure 2 , the ground clamping mechanism for the high-altitude grounding device of the present invention includes a base 1, the top of the base 1 is provided with a terminal pile head 2 and a clamp arm, and the ground wire 3 is connected to the terminal pile head 2; There are two clamp arms, respectively the first clamp arm 4 and the second clamp arm 5; the first clamp arm 4 and the second clamp arm 5 are hinged to the top end of the base 1 through a hinge portion 6 ; The first clamp arm 4 and the second clamp arm 5 are sheathed with a movable chuck 7, and when the movable chuck 7 moves up, the distance between the two clamp arms is reduced to realize the clamping action, and the moving When the chuck 7 moves down, the distance between the two clamp arms increases to realize the release action;

[0023] The inside of the base 1 is arranged in a threaded hole, and a rotating shaft 8 passes through the threaded hole, and the rotating shaft 8 is threadedly...

Abstract

The invention discloses a high altitude grounding device grounding clamp mechanism comprising a pedestal; the top of the pedestal is provided with a wiring pile head and clamp arms; the wiring pile head is connected with a ground line; the clamp arms comprise a first clamp arm and a second clamp arm respectively hinged to the top of the pedestal through a hinge portion; the first and second clamp arms are sleeved by a mobile chuck; the mobile chuck moves upwards to realize a clamp motion, and moves downwards to realize a release motion; a thread hole is arranged in the pedestal, a rotary shaft penetrates the thread hole, and is screwed with the thread hole; the top of the rotary shaft is fixed with the mobile chuck; the bottom of the rotary shaft is fixed with a clamp board. The high altitude grounding device grounding clamp mechanism allows repair people to fast ground, is simple in structure, and the grounding clamp and release motions are simple and reliable; the high altitude grounding device grounding clamp mechanism is high in grounding operation efficiency.

Description

technical field [0001] The invention relates to a ground clamping mechanism for a 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 importan...
