Assembly type bridge prefabricated pier cap turnover device

The utility model belongs to the technical field of bridge prefabrication, and particularly relates to an assembly type bridge prefabricated pier cap turnover device. Comprising a support, two overturning platforms are arranged on the support, rotating shafts of the two overturning platforms are located on the sides close to each other, the bottoms of the overturning platforms are connected with a top overturning mechanism, and vertical frames are arranged below the sides, away from each other, of the overturning platforms and used for supporting the overturning platforms in the horizontal state. A plurality of back beams are distributed on the sides, close to each other, of the overturning platforms, the sides, facing the overturning platforms, of the back beams are perpendicular to the overturning platforms, the length of the back beams conforms to the width of a seam between the two overturning platforms, and the back beams on the two overturning platforms are staggered from each other; according to the de
