[0042] The working principle of this utility model is as follows: When the dewatering machine is running, it needs a support roller to support its force and ensure smooth rotation. Due to the large weight of the dewatering machine, and the inevitable damage to the support roller during long-term operation, when the support roller needs replacement, the pressure plate bolts and movable pressure plates on both sides of the support are removed. The roller can then be removed from the support. Next, the seals on both sides of the roller are removed, and a lifting mechanism is installed. The hook of an overhead crane or electric hoist is used to lift the support roller and lower it, allowing for further disassembly. After disassembly, the new support roller is hoisted onto the support for installation. After installation, to prevent the lifting mechanism from affecting the rotation of the support roller, the lifting mechanism is removed and the seals are replaced. The pressure plate bolts and movable pressure plates are then installed, enabling quick replacement of the support roller. The lifting mechanism also makes the originally heavy and inconvenient roller easier to lift. Furthermore, the seals prevent impurities from entering the threaded holes and annular holes on both sides of the roller during operation, facilitating the installation of the lifting mechanism. Multiple lifting mechanisms allow the support rollers to be lifted vertically from any position, eliminating the need to rotate the rollers to a designated position for lifting, making the lifting process more convenient.

[0043] This invention utilizes a lifting mechanism threadedly connected to both sides of the roller, facilitating the lifting and installation of the roller when replacing easily damaged components. Furthermore, after lifting, the lifting mechanism is removed and replaced with a sealing plug to prevent the threaded holes and annular holes on both sides of the roller from becoming clogged with impurities during equipment operation, thus ensuring smoother and more efficient production. By incorporating the lifting mechanism and sealing plug, the support roller can be lifted and replaced more easily, preventing prolonged maintenance from impacting production schedules, simplifying maintenance, and making production smoother and more efficient.

[0044] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
