A drain wire fixing device for live work on distribution lines

Abstract

The invention discloses a drainage line fixing device for live working of a distribution line, belonging to the technical field of electric operation auxiliary equipment. The drainage line fixing device comprises a lock rod and a lock head. The lock head comprises a clamp seat, a clamp head and a pressing clamp, the clamp head is arranged on the clamp seat through a clamping clamp, the clamp headcomprises a first clamp block, a second clamp block, a positioning spring and a positioning bolt, the first and second clamp blocks are connected, the positioning bolt penetrates the first and secondclamp blocks, the positioning spring sleeves the positioning bolt, the two ends of the positioning spring are respectively butted against the first and second clamp blocks, the positioning spring is in a compression state, and the end portion, extended out of the first and second clamp blocks, of the positioning bolt is screwed with a positioning nut. When the positioning nut is regulated, the flexible state of the positioning spring is changed, by employing the relative position of the first clamp block and the second clamp block, the opening of an upper clamp groove is regulated to facilitate regulation of the size of the upper clamp groove according to the concrete model of the drainage line fixing device and more facilitate the purpose of the effective fixing of the drainage line in the electrifying operation process.

Description

technical field [0001] The invention relates to the technical field of electric power work auxiliary equipment, in particular to a drain wire fixing device for live work on power distribution lines. Background technique [0002] At present, during the non-stop maintenance of 10kV power distribution lines in my country, when performing operations such as live replacement of equipment on the pole or disconnection and connection of drainage lines, in order to control the drainage lines to avoid phase-to-phase short circuits or grounding faults, the tower or crossarm is generally grounded first. After the body is insulated and shielded, the drainage wire is fixed with an insulating rope to ensure a safe distance between the drainage wire and the main conductor and at the same time the drainage wire can be fixed. When using insulated ropes to fix the drain wire, it is necessary to bend the drain wire forcibly and then hang it on the insulated lead wire. Not only do you need to use...

AI Technical Summary

Problems solved by technology

When using insulated ropes to fix the drain wire, it is necessary to bend the drain wire forcibly and then hang it on the insulated lead wire. Not only do you need to use a lot of shielding tools during the operation, but the safety factor is low and the work intensity is high. The forced bending of the drain wire may also damage the drain wire. In addition, if the drain wire is only hung on the insulated lead wire, the drain wire is easy to fall off from the insulated lead wire, which greatly affects the safety of live work

When carrying out live work, the operator will be inconvenient to move because of wearing insulating protective equipment. The operator cannot flexibly and quickly complete the action of binding and fixing the drainage wire with the insulating rope during the operation process. The operation is difficult and dangerous. high
