[0026] Please see Figure 1-4 This utility model provides a technical solution: a special lifting tool for roller rings, comprising:

[0027] Roller ring support frame 1 and roller ring 2, with roller ring 2 mounted on roller ring support frame 1;

[0028] Roller ring limiting structure, the roller ring limiting structure is located on roller ring support frame 1;

[0029] The roller ring limiting structure includes a positioning slide tube 4, an adjustable pressure plate 8, two connecting rods 7, a connecting plate 6, and a second electric push rod 14. The positioning slide tube 4 is bolted to the roller ring support frame 1. The adjustable pressure plate 8 is slidably sleeved on the outer surface of the positioning slide tube 4. One side of the adjustable pressure plate 8 is in contact with the roller ring 2. The second electric push rod 14 is fixedly installed inside the positioning slide tube 4. The telescopic end of the second electric push rod 14 is fixedly connected to the connecting plate 6. Both connecting rods 7 are fixedly connected to the side of the connecting plate 6 near the adjustable pressure plate 8. The ends of both connecting rods 7 away from the connecting plate 6 are fixedly connected to the adjustable pressure plate 8. Two sliding grooves 15 are opened on the side of the adjustable pressure plate 8 near the roller ring 2.

[0030] The roller ring limiting structure also includes an arc-shaped pressure plate 9, two sliding blocks 17, a moving plate 13, a first electric push rod 12, and a fixed plate 11. The fixed plate 11 is fixedly connected to the adjustable pressure plate 8. The first electric push rod 12 is fixedly installed on the top of the fixed plate 11. The telescopic end of the first electric push rod 12 is fixedly connected to the moving plate 13. The two sliding blocks 17 are slidably connected inside the corresponding sliding grooves 15. One side of each of the two sliding blocks 17 is fixedly connected to the moving plate 13, and the side of each of the two sliding blocks 17 away from the moving plate 13 is fixedly connected to the arc-shaped pressure plate 9.

[0031] An anti-slip pad 16 is fixedly connected to the bottom of the arc-shaped pressure plate 9. The anti-slip pad 16 is in contact with the outer surface of the roller ring 2.
