[0002] In the hydrogenation reaction process in the chemical production field, the efficient loading and convenient replacement of catalyst directly affect the reaction efficiency and equipment utilization. Traditional hydrogenation reactors generally use multiple bolts to fix the container holding the catalyst inside the reactor body.

[0003] However, when the catalyst activity decreases and needs to be replaced periodically, the container holding the catalyst needs to be hoisted and replaced to achieve the overall catalyst loading operation of the hydrogenation reactor. During the installation operation, maintenance personnel need to wear protective equipment and be suspended into the limited space of the reactor. Since the surface of the container is easily deformed by stepping on it, maintenance personnel need to adjust to a suspended and bent-over posture to loosen and tighten multiple bolts. In this case, the operation of aligning and rotating multiple bolts takes a lot of time.
