[0028] The main unit 100 includes a bottom plate 101, four corners of the bottom end of the bottom plate 101 are fixedly connected to support feet 102, and the lower ends of the support feet 102 are fixedly connected to rubber blocks 103;

[0029] The rust removal unit 200 includes two placement plates 201, which are fixedly connected to the base plate 101, on which a steel pipe body 202 is placed, a movable plate 203 is slidably connected to the base plate 101, a mounting frame 204 is fixedly connected to the outer side of the movable plate 203, a first motor 205 is arranged in the middle of the mounting frame 204, a connecting rod 206 is fixedly connected to the output end of the first motor 205, the connecting rod 206 is rotatably inserted into the movable plate 203, a mounting block 207 is fixedly connected to the connecting rod 206, a grinding sheet 208 is arranged on the outer side of the mounting block 207, a plurality of bolts 209 are threadedly connected to the mounting block 207, a plurality of threaded holes cooperating with the bolts 209 are opened on the grinding sheet 208, an adjusting component 212 for adjusting the movable plate 203 is arranged on the base plate 101, and a clamping component 214 for clamping the steel pipe body 202 is arranged on the base plate 101.

[0030] Among them, a plurality of T-shaped sliders 210 are fixedly connected to the outside of the connecting rod 206, and the mounting block 207 is provided with a plurality of T-shaped grooves 211 that cooperate with the T-shaped sliders 210. By providing the T-shaped sliders 210 and the T-shaped grooves 211, the T-shaped sliders 210 and the T-shaped grooves 211 cooperate with each other, making the installation of the grinding sheet 208 more stable.

[0031] Furthermore, the adjustment component 212 includes a fixed frame 212a, which is fixedly connected to the right end of the base plate 101. A second motor 212b is arranged in the middle of the fixed frame 212a. The output end of the second motor 212b is fixedly connected to a threaded rod 212c, which is rotatably inserted into the base plate 101. The movable plate 203 is threadedly connected to the threaded rod 212c. The base plate 101 is provided with a sliding groove 212d that cooperates with the movable plate 203.

Then, the second motor 212b is started, so that the output end of the second motor 212b drives the threaded rod 212c to rotate, and the threaded rod 212c drives the moving plate 203. Under the action of the thread of the threaded rod 212c, the moving plate 203 moves. Since the moving plate 203 is slidably connected to the limit rod 213 On, the movable plate 203 moves along the length direction of the limiting rod 213 until the grinding sheet 208 contacts the inner wall of the steel pipe body 202, and the first motor 205 is started, so that the first motor 205 drives the connecting rod 206 to rotate, and the connecting rod 206 drives the mounting block 207, so that the mounting block 207 drives the grinding sheet 208 to grind and remove rust on the inner wall of the steel pipe body 202. When the grinding sheet 208 needs to be disassembled and replaced, the bolt 209 is screwed out of the threaded hole on the grinding sheet 208, and then the T-shaped slider 210 on the mounting block 207 is slid out of the T-shaped slide groove 211 on the grinding sheet 208, so that the grinding sheet 208 is separated from the mounting block 207. The operation is simple and the grinding sheet 208 is easy to replace.
