Technical Field

[0001] The utility model belongs to the technical field of coal - fired belt conveying equipment in thermal power plants, and particularly relates to a roller support facilitating the replacement of belt rollers. Background Technique

[0002] Rollers are important components of belt conveyors. During the operation of the coal - fired system in thermal power plants, multiple - stage conveyor belts are required to transport raw coal. The role of the rollers is to support the weight of the conveyor belt and the materials. Due to the high - frequency and long - cycle operation of the rollers, problems such as abnormal noises and rotational jams are likely to occur, and the worn rollers need to be replaced frequently. In the process of replacing the rollers of the existing roller brackets, workers need to jack up the belt and manually remove or install the rollers. The replacement process is cumbersome and inefficient. Moreover, when jacking up the belt, it is easy to cause wear or scratches on the edge of the belt, affecting the service life of the belt.
