The spherical sliding damping device comprises an upper rotary table and a bearing table, a spherical hinge is arranged between the upper rotary table and the bearing table, a plurality of spherical damping mechanisms are evenly arranged on the bearing table around the spherical hinge by a circle, and the tops of the spherical damping mechanisms make contact with the upper rotary table. A plurality of spherical damping mechanisms are arranged around a spherical hinge, and a sliding ball can slide and rotate in a recess when the spherical hinge rotates, so that vibration energy generated by an upper beam body can be absorbed and digested in the sliding friction process of the sliding ball and the inner surface of the recess, and the vibration energy of the spherical hinge part is reduced; and vibration is transferred and absorbed to the periphery of the spherical hinge through the spherical sliding damping device, so that the spherical hinge vibration energy is prevented from being concentrated at the spherica
