[0003] Based on the above, the load-bearing wheels used in the centrifuges currently in use are integrally arranged, which is not convenient for quick replacement. When replacing, the shaft needs to be dismantled and concrete needs to be injected in advance for preparation, which is inconvenient for adding concrete during the centrifugation process.
