Description

An overhead ground wire ratchet wrench carrying wire tool

technical field

The utility model relates to the technical field of power transmission line construction, in particular to a ratchet wrench hand-hand tool for overhead ground wires in the construction of hoisting operations connected with double-angle iron hanging points of iron towers on power transmission lines.

Background technique

At present, the towers of power transmission lines mostly use wine glass towers and cat head towers. The hanging points of these tower-shaped cross-arm ground wires are double-angle steel and the plane is downward. Remove it from the pay-off pulley, and fix the ground wire at the hanging point of the ground wire with the connecting hardware after installing the ground wire suspension clamp. The following problems exist in:

(1) Since the standing position of the construction personnel on the tower is not the best position for shoulder carrying, the strength cannot be fully exerted during the shoulder carrying process, and it is difficult to use shoulder carrying to make the ground wire reach the proper position for installation.

(2) When the overhead ground wire is carried on the shoulder, due to the heavy weight of the overhead ground wire, many high-altitude workers have sprained their waists during the operation.

(3) Due to the effect of the tension of the ground wire, the higher the height and the greater the tension, the greater the force required. Many ground wires with large gear distances are operated, and the operators did not carry them to the position due to the strength. If it is not enough, the ground wire will fall off from the shoulder and the ground wire will fall to the ground.

(4) This operation method requires two people on the tower to work together. Due to the difference in standing position and height, the mutual cooperation is uncoordinated, the work efficiency is low, the labor intensity is high, and there are many safety hazards.

In order to solve the practical problems in the installation of overhead ground wires, the operators explored from the production practice and summarized some methods. The methods and tools for hoisting wires cannot be used due to the short connection fittings of the ground wire suspension clamps, and then developed A wire-lifting tool that uses channel-shaped steel to be stuck on the angle iron at the hanging point of the ground wire, but due to unreasonable force, this developed tool is easy to damage the angle iron, and the installation is not firm enough to be used. In practice, an installation tool suitable for hoisting overhead ground wires with double-angle iron hanging points was further summarized and developed, which solved the problem of overhead ground wire installation.
