[0020] The steel pipe base 17 is fixedly connected to one end of the base 22 , the steel pipe fixing frame 16 is distributed and arranged on the top of the steel pipe base 17 and is fixedly connected to the steel pipe base 17 , and the steel pipe 15 to be ground is placed above the steel pipe fixing frame 16 and contacts the steel pipe fixing frame 16 .

[0021] The propulsion assembly includes a hydraulic cylinder body 1, a hydraulic rod 2 and a connecting plate 3. The hydraulic cylinder body 1 is welded to one side of a base 22. A hole is opened on the side of the base 22 connected to the hydraulic cylinder body 1. One side of the hydraulic cylinder body 1 is connected to the hydraulic rod 2 through the hole opened on the base 22. One end of the hydraulic rod 2 is connected to the connecting plate 3. The top of the connecting plate 3 is welded to the bottom of the sliding plate 4. The hydraulic rod 2 drives the sliding plate 4 connected to it to move by pushing the connecting plate 3.

[0022] When the inner wall of the steel pipe 15 needs to be polished, the hydraulic cylinder 1 is started to push the hydraulic rod 2 to move, so that the hydraulic rod 2 pushes the connecting plate 3 to drive the sliding plate 4 to move in the sliding groove 21, and pushes the polishing assembly 24 on the top of the sliding plate to move toward the steel pipe 15.

[0023] The grinding assembly 24 includes a servo motor 6, a servo motor base 5, a rotating shaft 7, a rotating disk connector 8, a rotating disk 9 and a grinding wheel 14. The servo motor base 5 is fixedly connected to the top of the sliding plate 4, and the servo motor 6 is mounted on the servo motor base 5 by fixing screws. The output end of the servo motor 6 is connected to the rotating shaft 7, one end of the rotating shaft 7 is connected to the rotating disk connector 8, one end of the rotating disk 9 is concave, and the concave surface is welded to the rotating disk connector 8. The grinding wheel 14 is installed at the front end of the rotating disk 9 and when the grinding work starts, the grinding wheel 14 is extended into the steel pipe 15 to ensure that the grinding wheel 14 and the inner surface of the steel pipe 15 are in contact with each other to achieve grinding.

[0024] When the inner wall of the steel pipe 15 needs to be ground, the servo motor 6 is operated to drive the rotating shaft 7, and the rotating disk 9 connected to the rotating shaft 7 through the rotating disk connector 8 also rotates with the rotation of the rotating shaft 7, thereby driving the grinding wheel 14 on the rotating disk 9 to rotate to complete the grinding of the inner wall of the steel pipe 15.
