When the arch bridge unit needs to rise, the mobile stage surface is first moved toward the second stage surface. In the process of moving the stage, due to the action of the second inclined track set on the mobile stage track, the mobile stage surface rises and passes over the platform of the arch bridge and the second stage surface. When the mobile stage surface completely passes over the arch bridge unit, the arch bridge unit can be lifted along the arch bridge walking track, translated into place, and then the mobile stage surface is moved back and close to the arch bridge unit.

A winch can be used to simultaneously realize the lifting and translational actions of the arch bridge unit, thereby reducing the overall equipment cost. At the same time, in the initial state, the platform can be used as a stage, making full use of the limited stage performance space. BRIEF DESCRIPTION OF THE DRAWINGS
