The invention relates to a wedge type large-diameter round pipe column lifting and overturning device. The wedge type large-diameter round pipe column lifting and overturning device comprises a horizontal bearing steel plate, and an inclined support bracket is arranged on the upper surface of the bearing steel plate. The lower end of the support bracket is fixedly connected with the bearing steelplate, and a supporting seat is fixedly connected between the support bracket and the bearing steel plate. A support rod perpendicular to the bearing steel plate is arranged on the upper surface of the support bracket, and the upper end of the support rod is covered with a rubber ball. A support pad assembly for underlaying a round pipe column is disposed on the outer side of the lower end of thesupport bracket, and a supporting block for supporting the round pipe column in the round pipe column overturning process is disposed at the lower end of the support bracket. The supporting block is located on the bearing steel plate, and the rubber ball and the supporting block are arranged on the axis of the support bracket. The length of a connecting line of a point through which the supportingblock is in contact with the lower end of the round pipe column and the center of the rubber ball is not less than the difference between the diameter of the round pipe column and the radius of the rubber ball. The wedge type large-diameter round pipe column lifting and overturning device is simple in operation, simple in structure and high in safety and stability.
