Universal portable treading platform for ceramic post insulators with different diameters

The invention discloses a universal portable treading platform for ceramic post insulators with different diameters. The universal portable treading platform is mainly composed of a plurality of fan-shaped plates, fan-shaped plate connecting strips, wedge-shaped rubber cushion strips and reinforcing locking strips of the wedge-shaped rubber cushion strips. The fan-shaped plates can be clamped on the peripheral side of an insulator ceramic chip, the outer sides of the fan-shaped plates are connected through the connecting strips, the contact faces between the fan-shaped plates and the insulator ceramic chip are reinforced through the wedge-shaped rubber cushion strips and the reinforcing connecting strips of the wedge-shaped rubber cushion strips, every two adjacent fan-shaped plates are connected through the hinges, and the inner diameters of the multiple fan-shaped plates can be adjusted by opening and closing the hinges and increasing or decreasing the number of the fan-shaped plates. The inner diameter of
