Manual handling is difficult, and the surfaces of the rollers 210 and the belt 230 are easily damaged during the disassembly and assembly process.

[0023] To overcome the problems existing in the related art, an exemplary embodiment of the present disclosure provides a roller replacement tooling 100, as Figure 2 shown, for supporting the roller 210 when replacing the roller 210 of the belt 230 conveying device, wherein the roller 210 can be arranged on the roller bracket 220; the roller replacement tooling 100 may include: two tracks 110, and one or more rollers 120.

[0024] The two tracks 110, as Figure 2 、 Figure 3 shown, are parallel to each other and fixedly arranged, and can be used to extend along the axial direction of the roller 210 and be installed on the roller bracket 220. The material of any one of the tracks 110 has sufficient rigidity and hardness to ensure that under the action of heavy loads, the bending deformation does not exceed the allowable value, so as to extend the service life of the track, and can effectively bear the load and pressure of the roller, and can be made of metal materials such as iron and stainless steel. One or more cross bars 130 may be arranged between the two tracks 110, and the multiple cross bars 130 may be evenly arranged between the two tracks 110. The cross bar 130 may be perpendicularly arranged with the two tracks 110, and both ends of the cross bar 130 are fixedly connected to the two tracks 110 respectively, and the connection method may be welding or the like. The length dimension of the track 110 may be longer than the length dimension of the roller 210 and can extend out of the roller bracket, which is convenient for disassembly and assembly.

[0025] One or more rollers 120, as Figure 2 、 Figure 3 shown, may be arranged between the tracks 110 and supported by the track 100, and can be used to rotate along the extending direction of the track 110 between the two tracks 110 to convey the roller 210.

Washers, lock nuts or other locking devices can be used, which can effectively prevent the bolts from vibrating under vibration or load changes. By positioning with the bolt clamp, the movement of the rail 110 on the roller bracket 220 can be restricted. In the embodiments of the present disclosure, by providing the bolt clamp and the mounting holes, the rail 110 and the roller bracket 220 can be cooperated to restrict the movement of the rail 110 on the roller bracket 220. The fastening force of the bolt clamp provides a strong clamping force, improves the stability of the rail 110 on the roller bracket 220, can be suitable for conveying rollers 210 with larger weights, and ensures the reliability and stability of the replacement of the roller 210.

[0032] In some embodiments, the roller replacement tooling 100 may further include: an extension device, which can be arranged at the end in the extending direction of the rail, is slidably connected to the rail 110, and can be used to slide along the extending direction of the rail to extend the length of the roller replacement tooling 100 in the extending direction of the rail. The extension device can be a guide rail, and the guide rail can be slidably connected to the rail 110 on the side of the rail end to extend the length of the roller replacement tooling 100 in the extending direction of the rail 110. The extension device can have sufficient load-bearing capacity to support the load during the roller replacement process. In the embodiments of the present disclosure, by providing the extension device, the extension device can be slidably connected to the rail 110, and the length of the extension device can be adjusted according to actual needs. When the roller 210 is long and the length of the rail is short, the length of the rail 110 can be extended, which is convenient for replacing the roller 210, is beneficial to the roller replacement tooling 100 to adapt to different scenarios, and has a wider applicability.

[0033] In some embodiments, such as Figure 3As shown, the top surface of the track 110 extends upward to form a limiting piece 140, which can be used to limit the movement of the roller 210 in the width direction of the track 110. The limiting piece 140 can be rectangular, located on the upper surface of the track 110, and fixedly arranged with the track 110. The setting method can be welding or the like. The material of the limiting piece 140 can be a hard material such as steel. There can be two or more limiting pieces 140. Two limiting pieces 140 can be respectively arranged on two tracks 110, and the two limiting pieces 140 can be arranged correspondingly. Multiple limiting pieces 140 can be evenly arranged on two tracks 110, and the limiting pieces 140 on the two tracks 110 correspond to each other, which can effectively limit the movement of the roller 210 in the width direction of the track 110.
