[0026] The following will further elaborate on this application in conjunction with the attached Figure 1 drawings.

[0027] The embodiment of this application discloses a device for replacing the frame roller of a rolling mill. Refer to Figure 1 , a device for replacing the frame roller of a rolling mill includes a mounting seat 1, a motor 2, a reel 3, a steel wire rope 4, and a transmission roller 5.

[0028] Refer to Figure 1 , there are two mounting seats 1, and the two mounting seats 1 are symmetrically arranged on both sides of the frame roller 100. The mounting seat 1 includes a base 11 and a box body 12. There are two groups of box bodies 12, and the two groups of box bodies 12 are respectively fixed on the upper surface of the two bases 11. Each group of box bodies 12 has two, and the two box bodies 12 are symmetrically fixed on the upper surface of the base 11. There are two groups of motors 2, and the two groups of motors 2 are respectively fixed on the two bases 11. Each group of motors 2 has two, and the two motors 2 are symmetrically fixed on the upper surface of the base 11. There are two groups of reels 3, and the two groups of reels 3 are respectively arranged on the base 11. Each group of reels 3 has two, and the two reels 3 are respectively rotatably connected to the two box bodies 12.

The driving gear is fixed to the output end of the motor 2, the driven gear is fixed to the reel 3, and the driven gear meshes with the driving gear. Starting the motor 2, the motor 2 can drive the driving gear to rotate, and the rotation of the driving gear drives the driven gear to rotate, so that the reel 3 rotates.

[0030] Refer to Figure 1, two fixing blocks 7 are symmetrically fixed on the upper surface of the base 11. There are two sets of wire ropes 4, and each set of wire ropes 4 has two. One end of the wire rope 4 is fixed to the side of the fixing block 7, the other end of the wire rope 4 is tied to the frame roller 100, and the wire rope 4 is wound around the drum 3. The rotation of the drum 3 can make the wire rope 4 extend or contract. Thus, it is convenient to move the frame roller 100.

[0031] Refer to Figure 1 , the driving roller 5 is arranged on the top of the rolling mill frame, and the base 11 is placed on the driving roller 5. And the base 11 is detachably connected to the driving roller 5 through the lock 6. By fixing the lock 6 on the driving roller 5 and the mounting seat 1, the mounting seat 1 will not move when the wire rope 4 is relaxed or tightened, so that it is convenient for the wire rope 4 to accurately drive the frame roller 100 to move.

[0032] The implementation principle of a frame roller replacement device according to an embodiment of the present application is as follows: The mounting seat 1 is lifted to the driving roller 5 by a crane, and the maintenance personnel push the mounting seat 1 so that the mounting seat 1 moves to a specified position. The base 11 is fixed to the driving roller 5 through the lock 6. After the base 11 is fixed to the driving roller 5, the motor 2 is started, and the drum 3 is rotated through the transmission assembly in the box body 12 to relax the wire rope 4. The maintenance personnel lead the wire rope 4 to the frame roller 100 to be replaced and fix it on the frame roller 100, and then the motor 2 is started in the reverse direction to tighten the wire rope 4. During the tightening process of the wire rope 4, the frame roller 100 will be pulled out to realize the disassembly of the old frame roller 100. After the disassembly of the old frame roller 100 is completed, the new frame roller 100 is installed on the wire rope 4, the motor 2 is started to relax the wire rope 4, so that the new frame roller 100 moves to the frame to realize the installation of the new frame roller 100; the overall structure is simple and the cost is low.
