The conductor lifting device can reduce labor intensity, improve operation efficiency, and effectively strengthen the safety of live working, and also has the advantages of simple structure, convenience for operation, high practicability and the like.

Description

A double wire lifter for live work

technical field

The utility model belongs to the technical field of installation tools for power transmission lines, in particular to a double-conductor wire lifter for live work.

Background technique

In the construction of overhead transmission lines in power systems, the method of lifting and installing double conductors is usually that the operator stands on the cross arm of the tower pole, and lifts the two conductors one by one to the required level through two suspension ropes tied with simple wire lifting hooks. height, and tie the suspension ropes to the cross arms respectively, after the wires are tightened and fixed, untie and remove the suspension ropes. The main defect of this method is that the two wires are lifted one by one by manpower, which is time-consuming, labor-intensive, and low in efficiency; The third is high-altitude live working, the support surface is narrow, and the stand is unstable, which is not only very inconvenient to operate, but also has serious potential safety hazards. the

Utility model content

The purpose of the utility model is to provide a double-conductor wire lifter for live work that can reduce labor intensity, improve work efficiency, and operate safely.

The technical solution adopted to realize the purpose of this utility model is: a double-wire wire lifter for live work, which is composed of a wire hook, a pull plate, a screw rod and a nut matched with it, wherein the pull plate is worn on the wire The through hole provided on the hook is connected by a positioning pin, and the screw rod is connected to the upper end of the pull plate.

The wire hook is a double-hook anchor structure.

The hook part of the wire hook is provided with a tile-shaped liner.

The double-conductor wire lifter for live work of the utility model can reduce labor intensity, improve work efficiency, and effectively enhance the safety of live work. The wire lifter has simple structure, convenient operation and strong practicability.

Detailed ways

Referring to Fig. 1, the utility model double wire lifter for live work is composed of a wire hook 1, a pull plate 2, a screw rod 5 and a nut 6 cooperating with it, wherein a wire hook 1 is provided in the middle There is a through hole with a rectangular cross section, the pull plate 2 is mounted in the through hole, and is fixedly connected by the positioning pin 4, and the screw rod 5 is connected to the upper end of the pull plate 2. Conductor hook 1 is a double-hook anchor structure, which is used for lifting and suspending double conductors. A tile-shaped backing plate 3 is fixedly installed on the hook position of the wire suspension hook 1, so as to increase the suspension contact area of the wire and prevent the wire from being damaged. When the wire lifter is in use, it is suspended on the cross arm of the pole tower through the nut 6, and then the two high-voltage transmission wires to be installed are lifted and suspended on the wire hook 1, and the nut 6 can be rotated at this time. The screw mandrel 5 drives the pull plate 2, the wire hook 1 and the high-voltage transmission wire to rise to an optimal height suitable for installation, so that the high-voltage transmission wire can be easily installed and fixed. During the lifting, installation and fixing process of high-voltage transmission wires, the operator does not need to stand for operation, thus ensuring the safe distance between the operator and the live body above and the safety of live work, and improving the working efficiency.
