Abstract: In order to solve the problems of container loading and unloading caused by the different docking between the airport lifting platform vehicle and aircraft cargo track, the universal roller was developed, The technology of universal roller was investigated in the transmission device of the airport lifting platform vehicle. After the analysis of the structure and working principle of the universal roller, the combination relationship between the rotational direction of the universal roller and the moving direction of goods was set up; the mathematical model of universal roller was established and the mathematical calculation method and calculation formula were put forward to be successfully applied to the CNC machining. The experimental results in Ilyushin IL76 transport aircraft show that the airport lifting platform vehicle with universal transmission device can adjust the container in six directions of front, rear, left, right, clockwise and anticlockwise. Goods can be delivered to the cargo plane conveniently and efficiently, and the work efficiency will be greatly improved.
