Description

A linear tower overhead line lifter

technical field

The utility model relates to the field of power transmission line construction and operation maintenance tools, in particular to a linear tower overhead line lifter.

Background technique

At present, there are four ways to lift the overhead ground wire on the straight line tower of the transmission line:

1. The lifting method of round wood holding poles and lever hoists. In actual work, because the iron tower is made of smooth steel, and the distance between the fixed round hole on the cross arm and the edge is too far, it is difficult for the operator to directly handle The lever hoist is fixed above the hanging point of the overhead ground wire. The log holding pole that cooperates with the operation is 3m long and 150mm in diameter. Iron wires need to be wound on the log holding pole, and then hooked with a hand hoist. This kind method expends greater physical strength in the operation process of the operator, and the risk factor is high.

2. Lifting method with big rope and pulley block. This method consumes a lot of manpower and material resources, and there is a large risk factor when the tower is high or the load of the overhead ground wire is large.

3. Single lead screw hook lifter. The length of the hook of this kind of wire lifter is fixed, and it can only be suitable for a lifting method of a distance, and the height cannot be adjusted. The contact area between the bottom surface of the lifter and the cross arm of the overhead ground wire is small, and the lifter is a single-sided screw, so the force is not uniform when lifting the overhead ground wire. In case of strong wind, the work is more difficult.

4. Overhead ground wire lateral force operation method. In this method, a lever hoist is used to work with double clamps. When the horizontal overhead ground wire is not stressed, it will drop for a certain distance. When installing the wire clip, it needs to be lifted by manpower to install it. This method complicates the operation in the transfer and operation of the tool, which not only causes the wear and tear of the overhead ground wire, but also poses a hidden danger to the personal safety of the operators.
