Abstract: With the large-scale development of wind turbine blades, it is more and more difficult for blades to be transported in wind turbine plants. At present, the traditional unpowered trolley is still used for blade transport, that is, the blade root trolley drives and steers with the forklift as the traction power source, while the blade tip trolley takes the manual steering as the steering power and the blade friction dragging as the traction force. The whole transit process employs a large number of workers, for which the safety risk is large, the transport operation is difficult, and the transport efficiency is low. In this case, the development of wind turbine blade automatic transfer vehicle has become the consistent goal of each wind turbine blade production enterprises. This paper mainly discusses a new kind of wind turbine blade automatic transfer vehicle equipment, the equipment mainly includes the root and tip of the blade transfer car body, car drive system, two-car control system, two-car linkage correction system, hydraulic automatic lifting system, safety obstacle avoidance system and other parts. The application of automatic transfer vehicle equipment can effectively reduce the difficulty of wind turbine blade transport, reduce the safety risk of blade transport, reduce the manufacturing cost of wind turbine blade, and improve the intelligent level of the blade manufacturing industry.
