The invention aims to solve the problems that:
1. in the spiral advancing process of the steel pipe, a linear traveling speed component and a spiral speed component are generated, so that the spiral speed component is counteracted when the real-time linear traveling speed of the steel pipe is measured;
2. the steel pipe body is not an absolute flat structure, i.e. the section of the steel pipe is not an absolute circular structure, and the steel pipe has an ovality problem, so that the steel pipe can jump up and down in the spiral advancing process.
Aiming at the problem 1, the invention is realized by the double rows of crawler belts and the crawler wheel hubs arranged on the double rows of crawler belts, the crawler wheel hubs on each row of crawler belts are arranged in parallel, and the steel pipes are arranged on the tangential lines of the outer edges of the two rows of crawler wheel hubs (as shown in figure 1), so that the technical scheme can offset the rotation speed component of the steel pipes during spiral conveying;
