The ground wire paying-off is a key link for constructing a power line, and the operation steps comprise: traction cable, traction tension control, fixed control, etc.
When a cable is pulled, in order to ensure that the cable is smoothly pulled to a wire tower, people usually pay off by means of a paying-off pulley hoisted to the wire tower, and the operation principle is as follows:
During paying off, an operator connects the traction cable, the wiring board and the cable into a whole, then the traction cable is led into the frame of the paying-off pulley, the traction cable is put on the wire wheel of the paying-off pulley, the other end of the traction lock is pulled by the bottom winch to drive the wiring board and the cable to move together, and the traction cable and the cable reduce working friction by means of the rolling action of the wire wheel, so that the traction cable drives the wiring board and the cable to move smoothly among a plurality of wire towers, and paying-off operation is completed.

Firstly, when paying off, the wiring board is an irregular plate-shaped object, the attaching degree of the wiring board and the wire wheel is poor, irregular bulges on the wiring board rub or collide with the wire wheel when a cable and a traction cable pass through the wire wheel, the phenomenon that the wire wheel is dragged by the wiring board is generated, the wire wheel is pulled up together with the whole paying off pulley when dragging, the wiring board is separated from the wire wheel instantly until reaching a limit position, the paying off pulley swings back and swings on a wire tower greatly at the moment, the connection part of the paying off pulley and the wire tower is impacted by the swinging, and the safety of the paying off pulley is threatened.
In addition, when the wiring board drags the line wheel, still block the frame of unwrapping wire coaster easily, and then lead to the traction wire to drag the unwrapping wire coaster directly, break the hoist cable easily and lead to the unwrapping wire coaster to fall, serious even can the company line tower be pulled and toppled over.
Finally, the number of the wire wheels and the frame width on the traditional paying-off pulley determine the passing number of the paying-off cables, and the paying-off pulley is of an unadjustable fixed structure, so that the paying-off pulley needs to be carried with various specifications in order to meet different paying-off requirements, the paying-off pulley is very complicated, the passing number of the cables cannot be adjusted in the paying-off process, after the paying-off pulley is hoisted to a wire tower, if the passing number and the passing performance of the paying-off cables are required to be adjusted, the paying-off pulley can only be hoisted again and replaced, and the operation flexibility and the adaptability are poor.
