Large radar array surface maintenance lifting device

The invention discloses a maintenance lifting device for a large radar array plane, which comprises a driving unit, a guide rail, a tackle, a main platform and a mobile platform, the driving unit is located at the top end or above the radar array plane, the guide rail is directly connected with the radar array plane, the tackle is slidably connected with the guide rail, the driving unit is connected with the tackle, and the main platform is connected with the tackle. The guide rail is arranged on the main platform, the movable platform is located below the guide rail, the pulley is detachably connected with the main platform, when the radar array plane needs to be maintained, the main platform is connected with the pulley, and when the radar array plane does not need to be maintained, the main platform is separated from the pulley and can move away along the movable platform. The beneficial effects of the invention are that the system is more suitable for a large radar array plane with pitching requirements,
