The insertion rod is inserted into the eyelet of the ear plate 103 and the first connecting hole 2031 or the second connecting hole 2032, so that the upper platform 1 can be relatively fixed on the base frame 2 in different tilt states, thereby meeting different working conditions.

[0051] Working principle: The two sides of the bridge deck composite plate that needs to be reversed are sequentially passed through the composite plate slots of each locking device and placed flat on the top surface of the upper platform. The bridge deck composite plate and the locking plate are relatively fixed by tightly inserting the wedge block 406 into the slot 4033. Each hydraulic jack is actuated to push the corresponding jacking arc plate up. The jacking arc plate pushes the bridge deck composite plate to arch upward for deformation. At the same time, the locking plates of the locking devices on both sides of the bridge deck composite plate rotate upward as the bridge deck composite plate deforms. When the deformation of the bridge deck composite plate meets the requirements, the hydraulic jack is reset, and the jacking arc plate moves downward away from the bridge deck composite plate under the action of gravity, and then the subsequent welding operation is performed on the reverse-deformed bridge deck composite plate.
