Abstract

The invention discloses a one-traction-four-spreading rope-guiding method, and relates to the field of traction and spreading of transmission line wires. In the wire traction and deployment process of a power transmission line, wire traction and deployment of one traction and multiple traction plates are commonly applied, but the wire needs to be deployed and deployed by a traction rope before deployment, and at present, the traction rope is mostly pulled by a single wire during deployment, so that the traction efficiency is relatively low. According to the method, when the traction ropes are unfolded, one traction rope is used for traction four traction ropes through one traction plate, and when four second traction ropes are used for traction, the ropes are separated base by base. The four traction plates are used for traction and rope separation of the four traction ropes, so that the traction efficiency of the traction ropes can be effectively improved, the working efficiency is greatly improved compared with that of a single traction rope or a small number of traction ropes, the four traction ropes can be simultaneously and parallelly traction, the waiting time and repeated operation are reduced, and the whole traction operation period is shortened.
