Abstract

The utility model discloses a fixing device for a wire lifter of a power transmission wire, which has a base body matched with a wire rod of the wire lifter, and L-shaped hanging lugs are arranged on both sides of the base body. The fixing device can make the wire lifter hang on the cross arm stably, carry out the wire lifting operation conveniently, and can prevent the screw rod from moving and falling off during the wire lifting operation, thereby reducing labor intensity and improving work efficiency. It also has the advantages of simple structure, convenient operation and strong practicability.

Description

A wire lifter fixing device for power transmission wire

technical field

The utility model belongs to the technical field of installation tools for power transmission lines, in particular to a wire lifter fixing device for power transmission wires.

Background technique

In the lifting operation of large cross-section and multi-split conductors in power system transmission lines, the traditional method of lifting and installing transmission conductors is usually that the operator stands on the cross arm of the tower pole, and passes through two hanging wires with simple wire lifting hooks. The rope lifts the two conductors to the required height one by one, and the suspension ropes are respectively tied to the cross arm, and after the conductors are tightened and fixed, the suspension ropes are untied and removed. 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. At present, some construction uses a special wire lifter, which is composed of a wire lifting hook, a wire lifting plate and a screw rod. The upper end of the screw rod is provided with a nut. During construction, the nut is placed On the cross arm, by turning the nut, the thread lifting plate and the thread lifting hook are driven upward through the screw rod. Although this kind of thread lifter is relatively easy to operate, the safety of the thread lifting method is greatly improved compared with the traditional method. The device is unstable, which brings great trouble to the operation, and the screw mandrel is easy to fall off from the two angle iron gaps of the cross arm.

Utility model content

The purpose of this utility model is to provide a wire lifter fixing device that can stably hang the wire lifter on the cross arm, facilitate the lifting operation of the wire, prevent the screw from falling off, reduce labor intensity, and improve work efficiency. .

The technical solution adopted to achieve the purpose of this utility model is: a wire lifter fixing device for power transmission wires, which has a base body that cooperates with the wire lifter screw rod, and L-shaped hanging lugs are provided on both sides of the base body.

Both the outer diameter of the seat body and the width of the hanging lugs are smaller than the gap between the two angle irons of the cross arm of the tower rod of the transmission line.

The wire lifter fixing device of the power transmission wire of the utility model can make the wire lifter hang stably on the cross arm, carry out the wire lifting operation conveniently, and can prevent the screw rod from moving and falling off during the wire lifting operation, thereby reducing the Labor intensity, improve work efficiency, the device also has the advantages of simple structure, convenient operation, strong practicability and so on.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

Referring to Fig. 1, the fixing device for the wire lifter of the utility model has a base body 1, and a through hole is provided in the center of the base body 1 for wearing and fitting with the wire lifter screw 4. L-shaped hanging lugs 2 are provided on both sides of the base body 1 for hooking with the cross arm angle iron 3 of the transmission tower rod. The outer diameter of the base body 1 and the width of the hanging lug 2 are both smaller than the gap between the two angle irons 3 of the transmission line tower rod, so that it is convenient for the fixing device to pass through the gap between the two angle irons 3 of the cross arm . When the device is in use, it can be worn on the wire lifter screw 4 first, then the nut 5 of the wire lifter is screwed on the upper end of the screw rod 4, and then the device passes through the transmission line tower from below The gap between the two angle irons 3 of the cross arm is rotated 90°, and the hanging lugs 2 are hooked on the two angle 3 irons of the cross arm, so that the thread lifter can be hung on the cross arm stably, conveniently Carry out the thread lifting operation, and can prevent the screw rod from moving and falling off during the thread lifting operation.

Claims (2)
