Unmanned aerial vehicle airborne photoelectric pod lifting system

The invention relates to an unmanned aerial vehicle airborne photoelectric pod lifting system so as to solve the problems that an existingunmanned aerial vehicleairborne photoelectric platform vibration reduction lifting device depends on belt transmission to work, the phenomenon of belt slipping possibly occurs, consequently, the working performance is unstable, and the reliability of a pod in the lifting process cannot be guaranteed. The lifting system comprises a supporting frame, two lead screws, two polished shafts, four driven chain wheels, a driving chain wheel, a motor, an upper limiting switch, a lower limiting switch, a control unit and a photoelectric pod mounting plate. Two nuts and two guide rings are arranged on the photoelectric pod mounting plate, the two lead screws penetrate through the two nuts correspondingly, the two polished shafts penetrate through the two guide rings correspondingly, the upper ends of the two lead screws and the upper ends of the two polished shafts penetrate through a
