Design of A Split Four-Wheel Multifunctional Traction Equipment

In the tower assembly process of transmission lines, large towers are mostly assembled with floor-to-ceiling double rocker arms, and in this case, four traction ropes need to be winch controlled. In this paper, a design scheme for hydraulic multi-functional traction equipment integrating four groups of traction wheels and adopting a split structure is proposed, which can complete the traction control of four wire ropes, and cooperate with the landing double rocker arm pole to carry out the construction of transmission line towers. Based on the principle of four-wheel multi-functional traction technology, the key points of the design of each system are discussed, and it is verified through the field application test of UHV transmission line tower that performance of the equipment meets the requirements of the power unit in the pole holding operation process, and it effectively improves the construction efficiency.
