Description

new towing tool

technical field

The utility model relates to a novel traction tool.

Background technique

Power transmission line construction Tight line construction is the most frequent construction project, and the usual method is: use traction wire rope to connect with the working hole of the two-piece plate at the lead end through two U-shaped screws for traction. Through work practice, it is proved that there are following shortcomings and deficiencies. 1) The construction work is intensive, and operators must connect or dismantle along the insulator string to the wire end. 2) The risk factor is high. Because the insulator cannot reach the full level during the traction process, the traction sheave groove is lower than the wire hanging point hole of the tension tower, and the suspension position of the pulley is limited, it is necessary to increase the over-drawing length of the wire to complete the tight hanging of the wire Operation. At the same time, during the tight hanging process, the operator should try his best to straighten the insulator to complete the tight hanging wire operation, which increases the difficulty of the operation for the operators on the tower and brings unsafety. 3) Increased construction costs: Due to the increase in the length of the wire over-drawing, higher requirements are placed on the strength of the tower cross arm and the traction wire rope. During the tight hanging process of the 220kV line, construction workers have to connect or remove along the insulator string to the wire end, which has a high risk factor. If the conductor is pulled at the tower body, the danger brought by the operator's wire operation is avoided. In the process of pulling the wire, due to the uneven force on the wire block, the block will tilt to the traction side. Therefore, it is necessary to pull out a section of wire during the pulling process. When the over-drawing length is reduced, it can bring great convenience to the wire tightening work. Moving the connection point between the wire and the insulator string forward will reduce the length of over-drawing. To sum up, moving the connection point between the wire and the insulator string forward will bring great convenience to the construction work.

Utility model content

The technical problem to be solved by the utility model is to provide a new type of traction tool, which transfers the connection point between the steel wire rope and the insulator string to the end of the insulator string, so as to reduce the over-traction length and reduce the risk factor in the construction process.

In order to solve the problems existing in the prior art, the technical solution adopted by the utility model is:

The new traction tool has a U-shaped groove in the middle of the main body that can be stuck on the two-piece plate. The heights of the two ends of the U-shaped groove are different, and the high end is provided with a screw, which is located at the high end of the U-shaped groove. The main body of the utility model extends out a handle-shaped body, and the top of the handle-shaped body is provided with a through hole.

The advantages and effects that the utility model has are:

1. The new traction tool is scientifically and reasonably designed according to the characteristics of traction construction, combined with the specific size data of the tower head and traction block. The whole body is made of aluminum alloy material, which is light in weight and strong in strength. Under the condition that the working strength can be guaranteed, the self-weight is reduced, which brings convenience to the transportation of the tower up and down. High tensile strength, not easy to deform, can withstand a maximum horizontal tensile load of 15T, fully meeting the requirements for tight hanging wires. Moreover, the length of over-traction will be shortened by 1.5-2 meters during construction, which greatly reduces the difficulty of tight-line construction. The time for tightening the thread is significantly shortened, from 40 minutes per thread to 20 minutes per thread, which greatly saves the construction time. Due to the shortening of the traction length, the traction force is reduced, which simplifies the traction work, especially the content of the tower reinforcement work.

2. The new type of traction tool is reliably connected to the working hole of the two-piece plate at the hanging point, and the traction is carried out by the traction wire rope, which changes the connection point between the conductor and the bottle string, and the operator does not need to work along the insulator string to the conductor end. Thereby avoiding the work of the high-altitude workers going out of the wire, and eliminating the potential safety hazard. Reduced the difficulty and intensity of the work. It greatly reduces the over-drawing length of the wire during the pulling process, improves the safety factor of the operation, and ensures safe production.

3. The new traction tool is suitable for tight-hanging operations in various renovation and new projects, which can shorten the construction period, ensure safety and reduce operating costs.

4. The U-shaped groove of the new traction tool is provided with screws, and the screws pass through the working eye of the two-joint plate and are fixed with the two-joint plate to prevent it from moving laterally.
