Safety belt hanger for extra-ultrahigh pressure main transformer flange

The invention discloses a safety belt hanger for an extra-ultrahigh voltage main transformer flange. The safety belt hanger comprises a C-shaped clamping seat, a transverse movable plate arranged in the clamping seat, a first lead screw in threaded connection with the upper portion of the clamping seat in a penetrating mode, a vertical insulation stand column fixedly connected to the outer side of the clamping seat and a hanging ring rotationally connected to the top end of the insulation stand column. The bottom end of the first lead screw is rotationally connected with a movable plate, the movable plate is slidably connected with a clamping base, and a second lead screw is arranged on one side of the clamping base. When the first lead screw and the second lead screw rotate, the main transformer flange is clamped in the clamping seat, then a hook of a safety belt is hung on the hanging ring, a reliable safety belt hanging point can be formed on the main transformer flange, and therefore the problem that no r
