The invention belongs to the technical field of prefabricated bridge vibrating and tamping devices, particularly relates to an adsorption-type prefabricated bridge bottom mould vibration trolley, and solves the problems of hollow joint, voids and other defects due to insufficient compactness as a conventional vibrating and tamping mode is adopted at a part, with a large use amount of rebars, of a prefabricated bridge. The adsorption-type prefabricated bridge bottom mould vibration trolley comprises a traveling device, an adsorption device and a vibrating device, wherein the traveling device comprises a trolley, and the adsorption device is a electromagnetic chuck which is mounted and fixed on the upper most layer of a trolley frame and corresponds to the middle part of each bottom mould cross beam. The invention has the benefits that the adsorption-type prefabricated bridge bottom mould vibration trolley provides strong bottom mould vibrating and tamping for concrete of the prefabricated bridge, so as to effectively improve the vibrating and tamping quality of concrete of the bridge body, particularly concrete at the bottoms of ends of the bridge, and avoid hollow joint of concrete at support plates.
