Rapid lifting mechanism of array antenna

The utility model relates to a lifting mechanism, in particular to a quick lifting mechanism of an array antenna. The lifting mechanism is composed of a lower supporting plate, an upper supporting plate, supporting lifters and an actuator. The upper supporting plate is installed on the lower supporting plate through a plurality of sets of supporting lifters. An actuator is fixedly mounted on one side of the lower supporting plate; and the supporting lifter comprises a plurality of groups of diagonal bracings which are arranged in parallel. According to the lifting mechanism, the upper supporting plate is pushed to ascend and descend through the diagonal bridging, the array antenna installed on the upper supporting plate can be driven to ascend and descend, the array antenna can be lifted out of the cabin body from the top of the cabin body, the array antenna is not shielded, and the array antenna is erected and withdrawn relative to the disassembly and assembly of the cabin body; the time for erecting and wit
