The utility model discloses a sliding conversion type swivel spherical hinge, which belongs to the technical field of bridge engineering, and comprises a lower spherical hinge and a middle spherical hinge, and the middle spherical hinge can horizontally rotate relative to the lower spherical hinge to form a first revolute pair; and meanwhile, an upper rotating plate is arranged on the side, away from the lower spherical hinge, of the middle spherical hinge, the upper rotating plate can horizontally rotate relative to the middle spherical hinge, a second rotating pair is formed, and when the first rotating pair fails, the second rotating pair is started through unlocking, and rotation construction continues. The sliding conversion type swivel spherical hinge is simple in structure and exquisite in design, the standby rotating pair is arranged in the swivel spherical hinge, so that when a conventional rotating pair cannot operate normally, normal use of the swivel spherical hinge is achieved through the standby
