[0033] In one embodiment, the mounting bracket is further reinforced and fixed to the outer wall of the housing 1 by angle iron.

[0034] A third motor 306 is installed on the movable plate 305. The output shaft of the third motor 306 is connected to a threaded rod 307 via a coupling. The threaded rod 307 has two threads on its surface, which are arranged in opposite directions. The threaded rod 307 is rotatably mounted on the upper end of the movable plate 305 via a fixed seat. A movable plate 308 is threadedly connected to the threaded rod 307. A guide rod 309 is connected to the movable plate 308.

Figure 7 The capped column shown passes through the limiting groove 7 and the sliding groove 6 from bottom to top. When the sliding groove 6 rotates, it will move closer or further away from each other under the limitation of the arc-shaped sliding groove 6 and the limiting groove 7, thereby realizing the clamping and releasing action.

[0038] In summary, with the help of the above-mentioned technical solution of this utility model, when it is necessary to fix the device, the first motor 201 is started through the control panel 4. Then the first motor 201 drives the first adjusting rod 202 to rotate, which in turn drives the first adjusting wheel 203 and the transmission belt 204 to rotate, thereby driving the second adjusting rod 206 to rotate as well. Then the adjusting gear 207 on the first adjusting rod 202 and the second adjusting rod 206 also rotates. Then the adjusting gear 207 moves and adjusts by meshing with the two racks 208, thereby causing the racks 208 to drive the limiting plate 209 to fix the device on the rolling mill.

[0039] When it is necessary to replace the disassembled rolls on the rolling mill, the first electric push rod 303 is activated via the control panel 4. The moving end of the first electric push rod 303 then drives the moving plate 305 to slide and rise on the guide column 304 for adjustment. Next, the third motor 306 is activated via the control panel 4. The output shaft of the third motor 306 drives the threaded rod 307, which in turn drives the movable plate 308 to move and adjust on the guide rod 309 and within the movable groove 5. This allows for adjustment according to different roll lengths, thus ensuring a better replacement effect. After the length adjustment is completed, the rolls are then... The control panel 4 starts the second electric push rod 311. Then, the moving end of the second electric push rod 311 drives the adjusting block 312 to move and adjust. When it moves to the position for changing the roll, the control panel 4 starts the fifth motor 313. Then, the output shaft of the fifth motor 313 drives the rotating rod 314 to rotate. Then, the rotating rod 314 drives the worm gear 315 to rotate. Then, the worm gear 315 and the worm wheel 316 mesh with each other and drive the adjusting plate 317 to rotate, thereby causing the clamping plate 318 in the sliding groove 6 to move and adjust, so that the clamping plate 318 retracts and clamps the disassembled roll on the rolling mill.

[0040] The fourth motor 310 is started via the control panel 4. The output shaft of the fourth motor 310 drives the second electric push rod 311 and the adjusting block 312 to adjust their angles, thereby enabling the replacement of rolls placed on different rolling mills. When it is necessary to remove the rolls from the rolling mill, the moving end of the first electric push rod 303 is driven by the control panel 4 to slide and rise on the guide column 304. Then, the second motor 301 is started via the control panel 4, and the output shaft of the second motor 301 drives the adjusting plate 302 to rotate 180 degrees. Then, the first electric push rod 303 is started again via the control panel 4, and the moving end of the first electric push rod 303 slides and retracts on the guide column 304. The disassembled roll is then placed on an external placement platform or the ground. The above process is repeated to reinstall the replaced rolls onto the rolling mill.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
