Multi-roller type rotating disc structure for bridge rotating body

A bridge swivel multi-roller type rotating disc structure comprises a lower bearing platform fixedly connected with a bridge pier, an upper rotating disc fixedly connected with a bridge and a rotating structure arranged between the lower bearing platform and the upper rotating disc, and the rotating structure comprises a circular groove formed in the upper surface of the lower bearing platform and a plurality of rotating rollers rotationally arranged on the upper rotating disc. The bottom face of the circular groove is a concave or convex conical face, the rotating rollers are conical, the inclination angle of the rotating rollers is the same as that of the bottom face of the circular groove, the axial leads of the rotating rollers extend in the radial direction of the circular groove, and the inherent problems that a traditional spherical hinge is complex in construction procedure, long in period, high in cost and not thorough in disc sealing are solved. The purposes of high construction efficiency, low risk
