[0002] Chinese patent CN218453714U discloses a roller frame for facilitating replacement of rollers. The roller frame for facilitating replacement of rollers is provided with a support plate and a positioning plate. When the shaped plate is driven by the threaded column to move in the vertical direction, the support plate and the positioning plate follow the movement of the shaped plate and enable the support plate to push the roller to rise and fall, thereby facilitating the smooth pushing of the roller between the first side bracket and the second side bracket. Compared with the method of removing the roller, it is easier to maintain the stability of the roller and avoid the side of the roller from scratching the lower surface of the conveyor belt, thereby ensuring the safe operation of the conveyor belt.

[0003] Although the utility model can effectively replace the rollers, when replacing some higher rollers, some other workpieces are needed for assistance. At the same time, the device is prone to collision with mine walls during transportation, resulting in damage to the workpieces, thereby affecting their service life. Utility Model Content
