Grounding wire safety operation device in power construction

Abstract

The invention discloses a grounding wire safety operation device in power construction, in order to solve the problems that the working flow is complex and a lead clip is difficult to suspend during the using process of a grounding wire. The grounding wire safety operation device in power construction comprises a grounding end clamping fitting, a lead clip, a loop chain clamping pin, a copper stranded wire, an operation rod, a cross-shaped connector and an electroscope, wherein the grounding end clamping fitting is connected with the lead clip through the copper stranded wire; a loop chain of the loop chain clamping pin is fixed at the tail part of the lead clip; and a clamping pin of the loop chain clamping pin is matched with the grounding end clamping fitting. The grounding wire safety operation device in power construction is characterized in that the lead clip is a firing-pin-type wire clip; a fire pin in the firing-pin-type wire clip is a folded-type firing pin; and the operation rod is assembled with the cross-shaped connector or the electroscope. The grounding wire safety operation device in power construction provided by the invention is suitable for the construction and overhauling of devices with voltage grade of 220kV and below, not only improves the suspending and dismounting operation efficiency with the unique structure, but also relives the labor intensity of working personnel, and guarantees the personal safety of the working personnel.

Description

technical field [0001] The invention relates to a safety protection operating device in the construction of power transmission lines, in particular to an operating device composed of a striker-type wire clamp and an operating rod, which is suitable for the smooth detachment of the wire end clamp of the electric grounding wire. Background technique [0002] With the rapid development of power grid construction in recent years, the power grid facilities of power supply enterprises in various places have been continuously improved, and the use of grounding wires has become increasingly frequent during power grid construction or maintenance. When hanging the conductor end of the grounding wire, the traditional method needs to pass the electroscope and the insulating operating rod to the high-altitude worker respectively, and the high-altitude worker uses two insulating operating rods to carry out the wire electric test and the grounding wire terminal clamp respectively. Suspensi...

AI Technical Summary

Problems solved by technology

When hanging the conductor end of the grounding wire, the traditional method needs to pass the electroscope and the insulating operating rod to the high-altitude worker respectively, and the high-altitude worker uses two insulating operating rods to carry out the wire electric test and the grounding wire terminal clamp respectively. Suspension works, and traditional striker-type grounding wire clamps are opened and closed by supporting striker (see attached figure 1 And attached figure 2 ), the support structure of the striker causes the direction of the impact force F between the conductor and the striker to deviate from the closed center line of the clamp when the wire is clamped on the hook, which can easily cause the clamp to not bite in place and the grounding wire cannot be hung properly, which delays the work time
