[0002] At present, during the process of conveying materials by belt conveyors in industrial enterprises such as cement, the belt conveyor rollers, as vulnerable parts, need to be regularly inspected and replaced manually. Affected by the structure of the belt conveyor itself or the equipment process layout, there are certain difficulties and dangers in the operation of replacing belt conveyor rollers.

[0003] Among them, the publication (announcement) number: CN219279373U discloses an auxiliary device for replacing belt conveyor rollers, including a foundation cross beam, a horizontal hand-cranked screw jack, and a belt bracket. A groove is opened inside the foundation cross beam, and a mounting block is fixedly connected in the groove. The horizontal hand-cranked screw jack is fixedly installed on the mounting block. The horizontal hand-cranked screw jack includes a first connecting plate, a second connecting plate, a third connecting plate, a fourth connecting plate, a first support rod, a second support rod, a driving rod, and a support block.

[0004] In the above solution, the belt is lifted by the belt bracket. However, it is found in the actual use process that the rollers are relatively large in size and need to be manually lifted by workers during the replacement process, resulting in a large operating intensity. Moreover, once they fall to the ground, they will cause certain harm to people. Therefore, an auxiliary device for replacing belt rollers is proposed. Content of the Utility Model

[0018] 2. For the auxiliary device for replacing the belt idler, through the provided sliding seat, sliding rod and positioning bolt, when it is necessary to adjust the distance between the two U-shaped support plates, the hand rotates the positioning bolt to separate the end of the positioning bolt from the sliding rod, and then pushes the sliding seat to move on the sliding rod, so that the distance between the U-shaped support plates at the upper ends of the two support rods can be adjusted, and thus idlers of different lengths can be lifted.

[0019] 3. For the auxiliary device for replacing the belt idler, through the limiting plates, rotating shafts and springs provided inside the U-shaped support plate, when the idler is placed inside the U-shaped support plate, the roller wall of the idler contacts the limiting plate, causing the limiting plate to rotate through the rotating shaft and compress the spring, so that the limiting plate has the function of elastic expansion and contraction, which can ensure that idlers of different diameters are lifted. At the same time, the buffering function can protect the idler.

[0020] The parts not involved in this device are the same as the prior art or can be implemented using the prior art. This utility model can automatically assist in lifting the belt idler, facilitating manual replacement of the belt idler, reducing the intensity of manual operation, and having relatively high safety.
