The methods used in the following examples are conventional methods unless otherwise specified.
[0027] [Example]
[0028] like Figure 1 , 2 As shown in Figure 3, according to the size of the hook head, a locking frame 6 is manufactured which can accommodate the roller changing push-pull hook head and the support roller bearing box hook head at the same time. The locking frame is provided with a support rod 5, a locking head 4, a locking rod 3 and an anti-skid plate 7. A hexagonal head 2 and a handle 1 are provided on the top of the locking rod 3, and an anti-skid plate 7 is provided on the lower end of the locking rod 3 and the inner surface of the locking frame 6.

Use the handle 1 to rotate the locking rod 3, and the locking rod 3 moves downward along the locking head 4. The anti-skid plate 7 at the lower end of the locking rod 3 and the anti-skid plate 7 at the bottom of the locking frame 6 clamp the hooked hook heads downward along with the locking rod 3.
[0030] When the locking rod 3 is locking and fixing the hook head, if there is space between the locking frame 6 and the left and right sides of the hook head, the pad 8 is connected to the anti-slip plate 7 on both sides of the locking frame 6. The pad 8 locks the hook head from the left and right sides to prevent the hook head from shaking left and right and becoming unhooked.
[0031] After locking and fixing the hook head, the push-pull device pulls the support roller bearing box, and pulls the support roller out of the rolling mill through the support roller bearing box. After the support roller is replaced, the support roller and the support roller bearing box are pushed into the rolling mill through the locked and fixed hook head using the push-pull device.
[0032] The utility model can effectively avoid unhooking during use, reduce roll changing time, and improve roll changing efficiency. At the same time, it can effectively avoid similar safety risks such as large shaking of the upper support roll caused by unhooking, and effectively protect the personal safety of operators.
