[0002] Early manual polishing relied on manual operation, which was inefficient and difficult to guarantee uniformity, especially in long pipe scenarios, where operators could not easily reach inside the pipe, resulting in polishing blind spots. Mechanical polishing tools such as rotary grinding wheels improved efficiency, but were limited by their rigid structure and could not adapt to complex pipe diameter changes, and long shaft drives were prone to vibration and torque loss.

[0003] Traditional equipment is difficult to adapt to ultra-long steel pipes. Due to the limitation of shaft diameter, traditional grinding equipment cannot effectively process the inner wall of ultra-long steel pipes, requiring the steel pipes to be spliced ​​in sections, which is time-consuming, labor-intensive, and poses safety hazards. Manual grinding is inefficient and the quality is unstable. Manual grinding is labor-intensive, inefficient, and it is difficult to ensure the comprehensiveness of grinding, which affects product quality and production efficiency. Existing equipment has structural defects and lacks versatility. Some equipment cannot adjust the grinding intensity or adapt to different pipe diameters, and its application scenarios are limited.

[0004] Manual grinding is difficult to perform on long pipes, easily leading to unevenness. It also requires certain manual grinding skills. Mechanical tools are limited by length and diameter, making it difficult to penetrate deeply or maintain stability. This results in low efficiency, high cost, difficulty in handling long pipes, and high maintenance costs. It is time-consuming and labor-intensive. Therefore, a device for rapid grinding and shaping of the inner wall smoothness of long pipes is proposed to solve the above problems. Utility Model Content
