Problems solved by technology

[0003] The existing split wire lifting tools are widely used in live work, but with the application of compact, multi-circuit transmission line technology on the same tower, the air gap distance between the transmission line wire and the tower is reduced, which leads to the traditional split lifting The application of wire tools is limited. When the air gap distance between the wire and the crossarm on the tower does not meet the minimum risk rate required by live work, it will obviously pose a threat to the life safety of live work personnel.

Embodiment 1

[0030] Such as Figure 1-5 As shown, the invention of this example is a wire lifting tool for split wires for live work, and the tool is suitable for six split wires; the tool is connected to the transmission tower through a hydraulic screw; one end of the hydraulic screw is provided with a The connection end of the tool 4 is connected, and the other end is provided with an insulating suspender 2 connected with the crossarm 1 of the transmission pole tower; the two sides of the tool are symmetrically provided with arc-shaped grooves and suspenders for placing split wires 5 from top to bottom. Hook; the tip of the tool is provided with a groove along its axis.

[0031] The tool is composed of two symmetrical wire-lifting arms, and the outside of the wire-lifting arms is provided with arc-shaped grooves and 2 hooks. The bottom end of the tool is formed by overlapping and connecting U-shaped plates provided at the bottom end of the wire lifting arm; two ends of the bottom end of...

Abstract

The invention relates to a live-working divided conductor lifting tool. The tool is connected with a transmission tower by use of a hydraulic lead screw; a tab connected with the lifting tool is arranged on one end of the hydraulic lead screw, while an insulating suspender connected with the cross arm of the transmission tower is arranged on the other end of the hydraulic lead screw; a cambered groove for holding a divided conductor and a lifting hook are arranged symmetrically on the two sides of the tool from top to bottom; a groove is formed in the top end of the tool in the direction of the axis of the tool. The live-working divided conductor lifting tool is capable of increasing the safety coefficient of the live working for the live working personnel.

Description

Technical field: [0001] The invention relates to a wire-lifting tool, in particular to a wire-lifting tool for split conductors in live work. Background technique: [0002] The wire lifting tool is one of the maintenance tools commonly used in the live work of the transmission line. It is mainly used to lift the wire, transfer the mechanical load borne by the insulator string, and withstand the electrical insulation of the corresponding voltage level. [0003] The existing split wire lifting tools are widely used in live work, but with the application of compact, multi-circuit transmission line technology on the same tower, the air gap distance between the transmission line wire and the tower is reduced, which leads to the traditional split lifting The application of wire tools is limited. When the air gap distance between the wire and the crossarm on the tower does not meet the minimum risk rate required by live work, it will obviously pose a threat to the life safety of li...
