Abstract: In order to improve the efficiency, safety, and reliability of high tower operations, a design scheme for mechanical operation automation assistance of tower auxiliary lifting devices based on load-bearing unmanned aerial vehicles is proposed. Through three steps of tracking the flight trajectory of the drone, planning the lifting path of the device, and controlling the operation process of the auxiliary lifting device, a tower mounted auxiliary lifting device mechanical operation automation auxiliary technology based on a load-bearing drone has been successfully designed, ensuring safety during the mechanical operation process. The experimental results show that the mechanical operation automation auxiliary design scheme of the tower auxiliary lifting device based on load-bearing unmanned aerial vehicles significantly reduces the difficulty and labor intensity of manual operation, reduces the operation errors caused by human factors, and effectively ensures the safety of operations.
