Portable grounding device for live work

Abstract

The invention provides a portable grounding device for live work, which belongs to the field of electric tools. The device includes an inverted U-shaped wire clamp, a door-shaped connecting frame, a hollow casing, a tilting mechanism and a spring set in the hollow casing, a T-shaped bar set in the spring, an insulating rod set on the tilting mechanism, and an inverted The U-shaped wire clamp is flexibly connected with the hollow casing through the door-shaped connecting frame. The device has the characteristics of stable wire clamping and convenient wire loosening. It is suitable for grounding of high-voltage wires in different directions such as horizontal and vertical angles. It has high safety, work efficiency and flexibility, and has small self-weight, low cost and strong practicability. Etc.

Description

【Technical field】 [0001] The invention relates to the field of electrical tools, in particular to a portable grounding device for live work. 【Background technique】 [0002] In modern society, high-voltage wires and cables can be seen everywhere, and the problem of safety insulation when repairing and testing them has become a major problem facing today. Seeking a feasible way to solve the problem has become a requirement to ensure the safety of construction personnel and improve the work efficiency of construction personnel. Long operating distance and large external interference are the common characteristics of these environments, so there are huge defects in the application of spiral grounding clamps and double tongue grounding clamps. The spiral ground wire clamp has greater stability when clamping the wire, but it is difficult to clamp the wire on the high-voltage cable with a large distance, and it clamps the wire through thread adjustment, and the operating lever nee...

AI Technical Summary

Problems solved by technology

The spiral ground wire clamp has greater stability when clamping the wire, but it is difficult to clamp the wire on the high-voltage cable with a large distance, and it clamps the wire through thread adjustment, and the operating lever needs to be twisted many times to make it work. The horizontal locking lever locks the wire in the clamp, which is extremely inconvenient to operate and greatly reduces work efficiency

Although the double-tongue type is easier to clamp than the spiral grounding wire clamp, the elastic force hook can be fixed on the wire through the tension spring of the two tongues, but the wire is located between the two tongues after hanging. At the top of the inverted figure-eight shape, because the wire is often in the outdoor environment of strong wind and heavy rain, and even under the action of wind, the wire will dance, causing the hook to turn over, causing the hook to fall off from the wire, resulting in temporary short circuit failure. Serious personal injury to maintenance personnel, so there is a great potential safety hazard
