ground clamp

Abstract

The invention discloses an earthing clamp. The earthing clamp comprises a support, a sliding support and a driving device, wherein a fixed clamp head is arranged at the upper end of the support; the sliding support is arranged on the support in the mode of being capable of vertically sliding, a sliding clamp head is arranged at the upper end of the sliding support; the driving device is used for driving the sliding support to slide. The driving device comprises a rack, a first gear, a bearing, a second gear, a swing support and a rotating mechanism, wherein the rack is fixedly arranged on the sliding support; the first gear is arranged on the support, and is connected with the rack in a meshed mode; the bearing is clamped and embedded into an arc-shaped groove formed in the support in the mode of being capable of sliding; a main shaft of the second gear is arranged on the bearing in a sleeving mode, and the second gear is connected with the first gear in a meshed mode; the swing support is arranged on the support in the mode of being capable of rotating, and is locked to the support through a locking mechanism; a main shaft of the second gear is arranged on the swing support in a sleeving mode; the rotating mechanism is arranged on the swing support and is used for driving the main shaft of the second gear to rotate. The earthing clamp is simple in structure, good in self-locking performance and convenient to operate.

Description

technical field [0001] The invention relates to the field of high-voltage wire detection tools, in particular to a grounding clamp. Background technique [0002] When performing maintenance or other work on high-voltage equipment or high-voltage lines, connect the high-voltage equipment or high-voltage lines to the ground wire through the grounding clamp to prevent the dangerous voltage and arc generated by the sudden call of the equipment or the induction of other nearby high-voltage live equipment and lines. The harm of voltage to the human body can also be used to discharge the remaining charge of power-off equipment and lines to avoid electric shock accidents and ensure the personal safety of workers. Therefore, it is a very important electrical safety measure to short-circuit the grounding wire of high-voltage equipment or high-voltage lines through the grounding clamp. However, due to the poor self-locking property of the existing grounding wire clamp, the grounding w...

AI Technical Summary

Problems solved by technology

However, due to the poor self-locking property of the existing grounding wire clip, the grounding wire clip may fall off during the operation of the operator. If the operator cannot find out in time, the maintenance work will lose safety protection and accidents will easily occur.

There are also some grounding clamps with better self-locking properties, but their structures are complex and inconvenient for operators to use.
