[0028] The present invention can illustrate its functional principle through the following operation modes:
[0029] When it is necessary to grind and derust the pipeline 10 to be polished, first, the operator lifts the pipeline 10 to be polished through a lifting device, so that the two ends of the pipeline 10 to be polished are aligned with the opposite circular abutting blocks 16, and the two The first electric push rod 7 drives the circular abutment block 16 to slide into the pipe 10 to be polished. When the contact is tight, continue to control the movement of the first electric push rod 7. At this time, the annular rubber pad 17 squeezes the two triangular blocks 25 through the abutting rod 20 on the sliding rod 15 to slide, and the triangular blocks 25 drive the slider 21 through the fixed rod 24. Slide out from the chute 19, the rubber abutment block 22 on the slider 21 is pressed against the inner wall of the pipe 10 to be polished, so that the pipe to be polished 10 is in a stable state. When the pipeline 10 to be polished is pressed tightly, the pipeline 10 to be polished will not be damaged, and then the pull rod 35 is pressed. The groove 31 is blocked, the grinding disc 28 on the bottom end of the sliding rod 27 is in contact with the surface of the pipeline 10 to be polished under the elastic force of the second spring 29, the motor 8 is started, and the driving gear 9 on the motor 8 is driven by the driven gear 5. The rotating rod 4 rotates, and the rotating rod 4 drives the pipeline 10 to be polished which is pressed against the circular abutting block 16 to rotate through the first electric push rod 7 , and then starts the second electric push rod 11 , and the second electric push rod 11 passes through the mounting plate 12 Drive the cleaning brush 13 to move to the left. When the cleaning end of the cleaning brush 13 is in contact with the surface of the pipe 10 to be polished, the side wall of the mounting plate 12 is just in contact with the side wall of the L-shaped plate 36. At this time, the cleaning brush 13 and the polishing The disc 28 moves to the left synchronously, the grinding disc 28 grinds the surface of the pipeline 10 to be polished, the cleaning end of the cleaning brush 13 cleans the surface of the pipeline 10 to be polished, and cleans the debris attached to the surface of the pipeline 10 to be polished to ensure good grinding effect.
[0030] The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. The equivalent replacement or change of the inventive concept thereof shall be included within the protection scope of the present invention.
