Aviation tray lifting and turnover device

The invention belongs to an aviation tray lifting and turnover device, particularly relates to a device capable of improving the production efficiency of aviation trays, and belongs to the technical field of aviation transportation unit load devices. The device comprises a body rack, a turnover mechanism, a winch, a guide pulley set and a steel wire rope. Through the principle that the force direction can be changed by a fixed pulley, the directions of steel wire ropes guided out from the two sides of the winch are changed through multiple pulleys, finally the tail ends of the steel wire ropesare placed at the positions of the four corners, and therefore four hooks are arranged at the tail ends of the steel wire ropes to hook tying rings at the four corners of a tray. By means of the device, large output pulling force can be generated by small input force, operation of lifting, turnover and transfer to the tray in the production process is convenient and rapid, manpower is saved, andproduction efficiency is e
