[0002] During the production process, ductile iron pipes (referred to as cast pipes) require a uniform coating of cement lining on their inner surfaces. This lining is evenly distributed through a centrifugal process. A cement lining machine is used to process the cement lining of cast pipes. The machine station requires a custodian device to centrifugally rotate the cast pipe.

[0003] The roller equipment for cement lining machines drives the cast pipe to rotate through the belt of the cast pipe drive mechanism. At present, the cast pipe drive mechanism of the roller equipment for cement lining machines is fixed and cannot be adjusted according to the diameter of the cast pipe. When processing different cast pipe linings, the original cast pipe drive mechanism needs to be dismantled and reassembled and adjusted according to the new pipe diameter so that the cast pipe drive mechanism can support the cast pipe of the new diameter. Adjusting the pipe diameter is time-consuming and labor-intensive, resulting in low production efficiency and high labor intensity. Utility Model Content
