The two sets of idler roller assemblies include a set of active idler roller assemblies and a set of driven idler roller assemblies. The active idler roller assembly is connected to the drive mechanism.

[0007] Each of the two sets of idler roller assemblies includes two idler rollers, and a support frame is provided between the two idler rollers. The support frame is movably connected to the lifting worktable, and the lifting worktable can move up and down along the support frame.

[0008] Furthermore, through holes are provided opposite to each other on the lifting work platform, and the support frame is disposed in the through holes and its bottom is fixed on the support platform.

[0009] Furthermore, the lifting assembly includes a hydraulic lifting cylinder located at the center of the support platform and the lifting worktable, the hydraulic lifting cylinder being used to drive the lifting worktable to move up and down.

[0010] Furthermore, the hydraulic lifting cylinder includes a cylinder body and a piston rod. The cylinder body is located inside the support platform, and the piston rod is located inside the cylinder body with its top connected to the lifting work platform.

[0011] Furthermore, the lifting assembly includes lifting guide rods located at the four ends of the support platform and the lifting worktable, and the lifting guide rods are disposed at the lower part of the idler roller.

[0012] Furthermore, the body of the lifting guide rod is located inside the support platform, and its upper surface is connected to the lifting worktable, allowing it to move up and down with the lifting worktable.

[0013] Furthermore, the support frame is a V-shaped support frame.

[0014] Beneficial effects: This application, by setting up a lifting worktable that can move up and down along the support frame and a rotatable roller assembly, allows for efficient installation of the support roller and bearing housing. First, the support roller is lifted away from the support frame, then the bearing housing is fixed. The roller assembly drives the roller to rotate, causing the roller's locking mechanism to align with the groove in the bearing housing. After assembling the support roller and bearing housing, the lifting worktable is lowered, allowing the assembled support roller and bearing housing to be safely placed on the support frame. Disassembly simply requires separating the bearing housing from the roller while keeping it horizontal.

[0015] This design reduces the impact force on the support roller bearing housing and roller during disassembly and assembly, making it safer and preventing damage to the roller. It is also reasonably designed, easy to operate, saves labor, and increases operational safety, making it suitable for application in the production process. Attached Figure Description
