Zusammenfassung:	The utility model discloses a synchronous lifting and rotating device. The synchronous lifting and rotating device comprises a base frame, a movable part, a lifting drive and a rotating drive, the movable part has a first stroke for lifting and a second stroke for rotating on the base frame; the number of the lifting drive is at least one, the first end of the lifting drive is arranged on the base frame, the second end of the lifting drive is in transmission connection with the movable part, the lifting drive has at least one-stage telescopic stroke, and the direction of the telescopic stroke is the same as that of the first stroke so as to drive the movable part to ascend and descend; the rotation driving movable part is in transmission connection to drive the movable part to rotate. The lifting device is applied to the field of tunnel construction, adopts the lifting drive with at least one stage of telescopic stroke, and can effectively reduce the overall installation distance of the lifting drive, thereby
