[0036] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0037] Reference Figures 1 to 6 , which is the first embodiment of the utility model, proposes a quick replacement device for the measuring roller 2 of the rolling mill 1, which is used to transport and replace the measuring roller 2 on the rolling mill 1, including: a conveying frame 3 is arranged at the bottom of the rolling mill 1; a guide rail 4 is arranged on the conveying frame 3; a conveying member 5 is slidably arranged on the guide rail 4, and the conveying member 5 is used to carry and transport the measuring roller 2; there are several lifting members 6, which are arranged on the rolling mill 1, and the lifting members 6 are used to fix and lift the measuring roller 2.

[0038] In this embodiment, the conveyor frame 3 is arranged at the bottom of the rolling mill 1, providing a stable support platform for the conveyance of the measuring roller 2. The guide rail 4 and the conveying member 5 that can slide on the guide rail 4 cooperate to quickly and smoothly convey the new measuring roller 2 to the position of the rolling mill 1 or transport the measuring roller 2 that needs to be replaced, which greatly saves transportation time. The lifting member 6 is arranged on the rolling mill 1, which can quickly fix and lift the measuring roller 2. Without complex manual operation and large lifting equipment, the measuring roller 2 can be accurately positioned and installed, which significantly improves the efficiency of the replacement operation. The entire replacement process is carried out through a special device, which reduces the direct participation of manual labor in the handling and lifting of heavy objects, and reduces the safety risks caused by improper operation, such as the probability of accidents such as being hit or sprained. The use of a quick replacement device can reduce the downtime of the rolling mill 1 caused by replacing the measuring roller 2, thereby improving the production efficiency and equipment utilization of the rolling mill 1.

[0039] As a further technical solution, it further includes: a plurality of fixing frames 7 are provided on the conveying member 5 , the fixing frames 7 are arc-shaped, and are used to prevent the measuring roller 2 from rolling on the conveying member 5 .

[0040] In this embodiment, the fixing bracket 7 is arc-shaped, matching the shape of the gauge roller 2. It fits snugly against the surface of the gauge roller 2, effectively preventing the gauge roller 2 from rolling on the conveyor 5. During transportation, the gauge roller 2 remains stable, and shaking or rolling will not affect the speed and safety of transportation, ensuring the efficient operation of the replacement device. This stable transportation method prevents the gauge roller 2 from colliding with the conveyor 5 or surrounding equipment, reducing the risk of equipment damage and extending the equipment's service life. When the new gauge roller 2 is transported to the installation location, the fixing bracket 7 allows the gauge roller 2 to accurately remain in the predetermined position, facilitating the fixing and lifting operations of the lifting member 6. This helps improve installation accuracy during the replacement process, ensuring that the gauge roller 2 is properly installed on the rolling mill 1, thereby ensuring the normal operation and measurement accuracy of the rolling mill 1. For the gauge roller 2 that needs to be replaced, the fixing bracket 7 also keeps it stable during transportation, facilitating subsequent maintenance or storage, and improving the orderliness and accuracy of the entire replacement process.

[0041] As a further technical solution, the fixing frame 7 has several limiting holes 8, and also includes: a limiting frame 9 that is detachably arranged on the fixing frame 7, the limiting frame 9 is also arc-shaped and has the same curvature as the fixing frame 7, and the limiting frame 9 has several through holes 10; a limiting rod 11 is slidably arranged on the fixing frame 7, and after sliding, the limiting rod 11 passes through or leaves the limiting hole 8 and the limiting rod 11, and the limiting rod 11 is used to fix the limiting frame 9.

[0042] In this embodiment, the limiting frame 9 cooperates with the fixing frame 7 to further secure the measuring roller 2. Both are arc-shaped and have the same curvature, allowing them to better conform to the surface of the measuring roller 2 and limit the measuring roller 2 from multiple directions, preventing it from moving or shaking in any direction. After the limiting rod 11 passes through the limiting hole 8 and the through hole 10, it can firmly secure the limiting frame 9 to the fixing frame 7, ensuring that the measuring roller 2 remains stably fixed during transportation and replacement, improving the safety and reliability of replacement operations. By adjusting the position of the limiting frame 9 on the fixing frame 7, it can accommodate measuring rollers 2 of different diameters.

[0043] As a further technical solution, the lifting member 6 includes: a plurality of winches 12, which are arranged on the rolling mill 1; a hook 13 is arranged at one end of the winch 12, and the hook 13 rises and falls when the winch 12 rotates; one end of the connecting line 14 is arranged on the hook 13, and the other end is used to fix the measuring roller 2.

[0044] In this embodiment, the winch 12 has a powerful lifting force, capable of quickly and stably raising the measuring roller 2 to the desired height. The provision of multiple winches 12 ensures a smoother lifting process, preventing the measuring roller 2 from tilting or shaking during the lifting process. As the winch 12 rotates, the hook 13 rises and falls accordingly, making operation simple and convenient. By controlling the rotation direction and speed of the winch 12, the lifting height of the measuring roller 2 can be precisely adjusted to meet different installation and removal requirements. A connecting wire 14, one end of which is attached to the hook 13, and the other end is used to secure the measuring roller 2, provides a flexible and versatile connection method.

[0045] As a further technical solution, the invention further includes: a plurality of lifting ears 15 are provided on both sides of the limiting frame 9 , and the connecting wire 14 is detachably provided on the lifting ears 15 .

[0046] In this embodiment, the lifting lugs 15 are provided on both sides of the limit frame 9, providing a clear connection position for the connecting line 14. The operator can easily connect the connecting line 14 to the lifting lugs 15 without having to find a suitable connection point on the measuring roller 2, which greatly improves the convenience of the connection operation. The detachable connection method allows the connecting line 14 to be quickly separated from or connected to the lifting lugs 15, which is convenient for adjustment and operation when replacing different measuring rollers 2. This flexibility improves the working efficiency of the replacement device and reduces the replacement time. The provision of multiple lifting lugs 15 can make the force on the connecting line 14 more uniform, thereby improving the stability during the lifting process. When lifting the measuring roller 2, the lifting lugs 15 can ensure that the connecting line 14 will not deviate or slip, so that the measuring roller 2 always remains in a balanced state.

[0047] As a further technical solution, the plurality of winches 12 are divided into two groups, one group is arranged directly above the guide rail 4, and the other group is arranged directly above the position where the measuring roller 2 needs to be installed.

[0048] In this embodiment, when a new gauge roller 2 needs to be installed on the rolling mill 1, the hoist 12 located directly above the guide rail 4 can first smoothly lift the gauge roller 2 from the conveyor 5 to a certain height, freeing it from the conveyor 5. Then, by adjusting the lifting height and angle of the hoist 12, the gauge roller 2 can be moved along an optimized path to the desired installation location on the rolling mill 1. This prevents collisions with other equipment or obstacles during the lifting process, improving operational safety and efficiency.

[0049] As a further technical solution, the present invention further includes: a roller 16 is rotatably provided on the conveying member 5 , and the roller 16 rotates within the guide rail 4 .

[0050] In this embodiment, the rotation of roller 16 allows the conveyor member 5 to move more smoothly along the guide rail 4, reducing friction and enabling the measuring roller 2 to be transported to the designated position more quickly. Compared to a system without roller 16, this significantly reduces transport time and improves the overall efficiency of the replacement device. The rotation of roller 16 within guide rail 4 ensures that the conveyor member 5 always moves along the designated track, without deviation or shaking. This is crucial for ensuring the stability of the measuring roller 2 during transport, preventing damage to the measuring roller 2 or safety accidents caused by unstable transport.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
