The invention discloses an old bridge dismantling and lifting device and method, and belongs to the technical field of bridge construction.The old bridge dismantling and lifting device comprises a bottom frame, the bottom frame comprises two symmetrically-distributed bottom plates, a plurality of stable structures distributed in a linear array mode are arranged between the two bottom plates, and two symmetrically-distributed baffles are arranged on the opposite sides of the two bottom plates; clamping blocks are fixedly installed on the sides, close to the bottom plates on the same side, of the two baffles on the same side, clamping grooves matched with the clamping blocks on the same side are formed in the opposite sides of the two bottom plates, movable grooves are formed in the inner walls of the clamping grooves, and positioning assemblies are arranged in the movable grooves. And the two baffles on the same side and the bottom plate on the same side are fixed through first bolts. Through the arrangement of the bottom frame and the stabilizing structure, the effect of supporting and stabilizing the bottom of the old bridge is achieved, through cooperation of the baffle, the top plate and the connecting plate, the stability of hoisting of the old bridge is kept, and the possibility of fracture of the old bridge is reduced.
