[0054] From the above description, it can be seen that the present application achieves the following technical effects:

[0055] In the embodiment of the present application, the automatic roll changing mode is adopted, the lifting mechanism 20 rotates in a predetermined direction, so that the lifting platform 50 moves from a first predetermined position to a second predetermined position, and drives the connecting piece 60 and the carrier 70 to move synchronously and directionally, achieving the purpose of rapid roll changing, thereby realizing the technical effects of reducing roll changing time and improving efficiency, and further solving the technical problems of low roll changing efficiency and long roll changing time in the existing support roller 80 roll changing operation which adopts the mode of manually lifting the work roller away from the roller transverse bridge.

[0057] Further, the driving component 201 is a hydraulic cylinder, and the hydraulic cylinder drives the rotating component 202 to rotate in a preset direction. It can be understood that the hydraulic cylinder realizes the telescopic motion through the pressure change of hydraulic oil, and under the control of the hydraulic system, the thrust of the hydraulic cylinder makes the rotating component 202 rotate in a preset direction.

[0058] The hydraulic cylinder as the driving component 201 has the advantage of providing large thrust and stable motion. The hydraulic driving system has excellent stability and high efficiency in the lifting operation with large load, and is particularly suitable for occasions requiring accurate control and large load. Through the telescopic control of the hydraulic cylinder, the lifting process of the lifting platform 50 can be accurately carried out.

The lifting main body 501 is usually composed of metal frames, support members, etc., which can bear load and ensure the stability of the lifting platform 50.

[0066] The movable part 502 refers to the movable part provided at the bottom of the lifting main body 501, which enables the lifting main body 501 to displace or adjust under certain conditions. The movable part 502 includes but is not limited to wheels, sliders, rollers, etc., so that the lifting platform 50 can be easily moved or adjusted in different use scenarios.

[0067] The movable part 502 can help the lifting platform 50 move on the horizontal plane, providing flexibility, especially when the platform needs to be moved from one position to another. These movable parts 502 usually slide or rotate in cooperation with the support structure to make the lifting platform 50 easier to adjust the position.

[0068] The bottom of the movable part 502 is provided with the bottom plate 503, which is the structural component at the bottom layer of the movable part 502, usually serving as a support and stabilizer. The setting of the bottom plate 503 can enhance the stability of the entire lifting platform 50, so that it can maintain stability during movement and prevent the platform from tilting or collapsing due to unstable or unbalanced forces.

[0069] The bottom plate 503 ensures that the lifting platform 50 can provide uniform support under different ground conditions. It can play a role in dispersing pressure and improving load-bearing capacity, especially when the lifting platform 50 carries a large load, the load-bearing capacity of the bottom plate 503 is particularly important.
