[0022] Specifically, the steel beam lifted by the hook is moved to one end of the box body 1, and is sent into the rust removal device from one end of the box body 1. The hook can move forward and backward in the hook channel 3 to adjust the position of the steel beam. Sandblasting begins after the steel beam is stable, and the sandblasting frame 2 begins to move from one end of the steel beam to the other end. During the sandblasting process, the rotating clamp 8 is continuously rotated back and forth, so that the sandblasting gun 9 reciprocates up and down for sandblasting. During the movement of the sandblasting frame 2, the sandblasting and rust removal of the outer surface of the steel beam is completed. The sandblasting gun 9 that can reciprocate up and down ensures that there is no dead angle in the rust removal. After the rust removal is completed, it is horizontally moved out from both ends of the device. Since the steel beam has a large self-weight and a large inertia, the movement of the steel beam is avoided in this process.

The elliptical wheel 22 is driven to rotate by the first driving motor 21, and the connecting rod 11 is regularly lifted. The I-shaped fixing rod 19 clamps the connecting rod 11, so that the connecting rod 11 can only move up and down under the action of the limiting groove 18. The connecting rod 11 drives the rotating clamp 8 to rotate around the connecting rod 7. When the connecting rod 11 moves downward under the elastic force of the compression spring 23, the auxiliary wheel 20 is always in the groove track of the elliptical wheel 22.

The hook can move forward and backward in the hook channel 3 to adjust the position of the steel beam. Sandblasting begins after the steel beam is stable. The sandblasting frame 2 starts to move from one end of the steel beam to the other end under the action of the second drive motor 10. During the sandblasting process, the rotating clamp 8 is reciprocated around the connecting rod 7 through the cam connecting rod device, driving the sandblasting gun 9 to reciprocate up and down for sandblasting. During the movement, the sandblasting frame 2 completes the sandblasting and rust removal of the outer surface of the steel beam. The sandblasting gun 9 that can reciprocate up and down ensures that there is no dead angle for rust removal.
