Although the rolls on the rolling mill can be transferred and replaced under the above lifting method, the ropes and the roll shafts of the rolls are connected by binding in the above lifting and roll changing method. In the above roll changing method, the bundling and disassembly of the rolls with the ropes before and after lifting is time-consuming, resulting in a relatively low roll changing efficiency.

[0008] Furthermore, a connecting column is welded at each of the four corners of the upper end of the hanging plate, and a hanging ring is welded at the top of each connecting column.
[0009] By adopting the above technical solution, the connecting column can connect the lifting ring and the hanging plate as a whole, and the lifting ring is mainly connected to the lifting rope on the lifting device.
[0010] Furthermore, the slide groove is formed on the installation cavity, the slider is slidably connected to the slide groove, and the slider is welded to the adjustment plate.

[0012] Furthermore, the electric slide rail is connected to the adjustment plate with bolts, and the adjustment plate is provided with a concave structure at the location of the electric slide rail.
[0013] By adopting the above technical solution, the electric slide rail can realize flexible adjustment of the distance between the clamping plates on the same adjustment plate to meet the demand for convenient clamping of rollers of different lengths.
[0014] Furthermore, the bidirectional threaded rod passes through the two adjustment plates, and the bidirectional threaded rod is threadedly connected to each of the adjustment plates.
[0015] By adopting the above technical solution, the two-way threaded rod will drive the two adjustment plates to move conveniently after rotation, so that the rollers can be conveniently clamped and released with the help of the clamping plates while the adjustment plates move.

[0019] By adopting the above technical solution, the clamping groove can effectively prevent the roller from rotating after clamping, so as to ensure the stable lifting and transfer of the roller.
[0020] (III) Beneficial effects
[0021] Compared with the prior art, the utility model has the following beneficial effects:
[0022] In order to solve the problem that the rollers on the rolling mill are currently replaced mainly by using hooks and ropes to lift and transfer the repaired grinding rollers to the frame, although the rollers on the rolling mill can be transferred and replaced under the above lifting mode, the ropes and the roller shafts of the rollers are connected by binding in the above lifting and roller changing mode. In the above roller changing mode, it is easy to spend a long time to bind and disassemble the rollers with the ropes before and after lifting, thereby making the roller changing efficiency relatively low. The utility model uses the design of a motor, a bidirectional threaded rod, an adjustment plate, an electric slide rail, and a clamping plate, so that the roller changing device can automatically clamp and fix the roller shaft of the roller according to the actual roller changing needs when in use. At the same time, after the rollers are lifted and transferred to the designated installation position, the clamping plates on both sides can be moved away from each other to achieve convenient separation of the device and the rollers. This design not only saves the tedious operation of bundling the rollers before lifting and replacement, but also saves the tedious operation of disassembling the ropes on the rollers after lifting, thereby improving the roller replacement efficiency.

After the bidirectional threaded rod 12 rotates under the drive of the motor 3, it will drive the two adjusting plates 11 to move conveniently, so that the rolls can be conveniently clamped and released with the help of the clamping plate 4 while the adjusting plates 11 move.
[0030] like Figure 1-Figure 3 As shown, in this embodiment, a connecting column 6 is welded at the four corners of the upper end of the hanging plate 2, and a lifting ring 1 is welded at the top of each connecting column 6. The connecting column 6 can connect the lifting ring 1 and the hanging plate 2 as a whole. The lifting ring 1 is mainly connected to the lifting rope on the lifting device. The slide groove 8 is formed on the installation cavity 7, and the slider 9 is slidably connected to the slide groove 8. The slider 9 is welded to the adjustment plate 11. The slide groove 8 and the slider 9 cooperate to ensure the smooth sliding of the adjustment plate 11. The electric slide rail 10 is bolted to the adjustment plate 11, and the adjustment plate 11 is located at the electric slide rail 10. The structure is a concave structure.
[0031] like Figure 1-Figure 3 As shown, in this embodiment, the bidirectional threaded rod 12 passes through the two adjustment plates 11, and the bidirectional threaded rod 12 is threadedly connected to each adjustment plate 11, the motor 3 is bolted to the hanging plate 2, and the motor 3 is connected to the bidirectional threaded rod 12 by a coupling. The motor 3 is mainly used to realize the convenient rotation of the bidirectional threaded rod 12, the clamping plate 4 is welded to the sliding block on the electric slide rail 10, and the clamping groove 5 is a V-shaped structure.
