When producing concrete pipe piles, concrete mix is ​​filled into the pipe pile mold equipped with a steel cage, and then the pipe pile mold is subjected to high-speed centrifugal motion on the pipe pile centrifuge to complete the production of the concrete pipe pile with a central cylindrical hole.

[0003] The current pipe pile centrifuge mainly includes an active roller and a driven roller, and the distance between the active roller and the driven roller is fixed, which is not applicable when centrifuging pipe pile molds of different specifications. Although some existing pipe pile centrifuges are provided with an adjustment mechanism for adjusting the distance between the active roller and the driven roller, due to the long length of the corresponding pipe pile mold, the active roller and the driven roller of the pipe pile centrifuge are also arranged long, and the stability and effect of the pipe pile centrifuge during adjustment are poor. Increasing the number of adjustment mechanisms to adapt to the length of the pipe pile mold also leads to an overly complicated structure and increased costs. Utility Model Content
