Description

A screw operating device for a wire lifter for power transmission wires

technical field

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

Background technique

In the construction of overhead transmission lines in power systems, the traditional method of lifting and installing transmission wires is usually that the operator stands on the cross arm of the tower pole, and lifts the two wires one by one through two suspension ropes with simple wire hooks. The required height, and the suspension ropes are tied to the cross arm 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. 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 wire lifter is easier to operate, the safety of the wire lifting is greatly improved compared with the traditional method, but, because the leading screw belongs to a metal tool, the safety distance is shortened in the operation process. In this case, the operator needs to stand on the cross arm and use a wrench to move the nut to lift the wire. Due to the limited position, the worker still feels inconvenient to operate, especially when working with live wires, the safety distance poses a serious threat to personal safety. threat.

Utility model content

The purpose of the utility model is to provide a wire lifter screw operating device for power transmission wires that can effectively eliminate the threat of the safety distance to the personal safety of the operator, is simple to operate, efficient and convenient, low in labor intensity, and high in operating efficiency.

The technical solution adopted to realize the purpose of this utility model is: a screw mandrel operating device for a wire lifter for a power transmission wire, which has a screw sleeve cooperating with the wire lifter screw rod, and a ratchet wrench is fixedly set on the screw sleeve, and the ratchet wrench The operating end is provided with an operating ring.

The screw rod operating device of the wire lifter for power transmission wires of the utility model realizes a relatively long-distance operation of the wire lifter through the setting of the ratchet wrench, thereby effectively avoiding the threat of a safe distance to the person, and the operator can hold the wire lifter with one hand. The tower rod can operate the wire lifter with one hand, thereby enhancing the stability of the stand, and the operation is more labor-saving and quicker. The device has the advantages of simple structure, convenient use and the like.

Description of drawings

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

Detailed ways

Referring to Fig. 1, the operating device for the wire lifter screw rod of the power transmission wire of the present utility model uses a screw sleeve 1 cooperating with the wire lifter screw rod 4, and a ratchet wrench 2 is fixedly set on the screw sleeve 1, and the operation of the ratchet wrench 2 There is an operating ring 3 at the end. Wherein, the ratchet wrench can be purchased directly on the market, and its structure will not be repeated.

When the rod operating device is in use, the screw sleeve 1 can be used to replace the nut of the wire lifter, screwed to the upper end of the screw rod 4 of the wire lifter, and the wire lifter is screwed to the transmission tower rod through the screw sleeve 1 on the crossarm. When lifting the wire, the operator can stand at the junction of the cross arm and the tower rod, hold the insulating operating rod, insert the hanging structure at the front end of the insulating operating rod into the operating ring 3, push and pull the ratchet wrench 2 reciprocally, and then the power transmission can be realized. Lifting of wires. Due to the long-distance operation, the threat to the person caused by the safety distance is effectively avoided, and the operator can hold the tower pole with one hand and operate the wire lifter with one hand, thereby enhancing the stability of the stand, and the operation is more labor-saving and quicker.

Claims (1)

1. transmission pressure line lifter screw mandrel operating means, it is characterized in that: it has a swivel nut that cooperates with the line lifter screw mandrel, and fixed cover is equipped with ratchet spanner on the swivel nut, and the operating side of ratchet spanner is provided with the operation ring.
