When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. The embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0031] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0032] Furthermore, the terms "first", "second", etc. are used only for descriptive purposes and are not to be construed as indicating or implying relative importance or a quantity of the indicated features. Thus, a feature defined with "first", "second" can include one or more of the features implicitly or explicitly. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0033] As described in the background art, in a hot strip mill production line, the rough rolling mill group controls the width of the strip steel through vertical rolls, when the vertical rolls need to be replaced, C-shaped hooks are usually used for operation, however, when the vertical rolls are transported to the production preparation workshop, since the workshop is generally not equipped with C-shaped hooks, when the vertical rolls are hoisted or laid down for disassembly of the bearing box and auxiliary equipment, the overhead crane and steel wire rope are usually used for auxiliary operation. However, during the hoisting of the vertical rolls, the steel wire rope directly contacts the vertical rolls, which is easy to slip, causing the vertical rolls to fall. During the laying down of the vertical rolls, the steel wire rope needs to overcome the vertical force and control the horizontal force, however, the steel wire rope is unstable when restraining the horizontal force, which is easy to cause the horizontal movement or sliding of the vertical rolls, thus, there is a great safety hazard in the laying down operation of the vertical rolls, which may cause damage to the equipment and personnel.

The vertical roll lifting appliance provided in the embodiment movably installs the vertical roll connecting piece 21 on the lifting appliance main body 10, so that the lifting appliance main body 10 can be quickly connected with the flat shaft head of the vertical roll. Meanwhile, the lifting appliance main body 10 is provided with the lifting connecting part 30, so that the lifting device and the lifting appliance main body 10 can be stably connected. The vertical roll lifting appliance provided in the embodiment is provided with the vertical roll connecting part 20 and the lifting connecting part 30 on the lifting appliance main body 10, which significantly improves the connection stability between the vertical roll and the lifting appliance and between the lifting appliance and the lifting device, effectively reduces the shaking and falling risk of the vertical roll. In addition, the vertical roll lifting appliance provided in the embodiment can simplify the operation process and make the installation and disassembly of the vertical roll more convenient, thereby greatly improving the work efficiency. The stable connection and the simplified operation not only reduce the possibility of accidents, but also further improve the overall safety.

[0035] In an optional embodiment, the vertical roll provided in the embodiment is a rolling mill vertical roll.

[0036] Referring to Figure 1 , Figures 3 to 7 In a specific embodiment, the first end of the lifting appliance main body 10 is provided with a first opening in communication with the containing cavity 11, and the flat shaft head can be arranged into the containing cavity 11 through the first opening. The vertical roll lifting appliance further comprises a guide part 40 arranged at the first end of the lifting appliance main body 10 and used for guiding the sleeving of the lifting appliance main body 10 on the flat shaft head, so as to facilitate the sleeving of the lifting appliance main body 10 on the flat shaft head. The first end of the lifting appliance main body 10 is provided with the first opening in communication with the containing cavity 11, so that the flat shaft head of the vertical roll can be arranged into the containing cavity 11 through the first opening. The guide part 40 is arranged at the first end of the lifting appliance main body 10, so that the sleeving of the lifting appliance main body 10 can be guided by the guide part 40 during the sleeving of the lifting appliance main body 10 on the flat shaft head, thereby reducing the sleeving difficulty of the lifting appliance main body 10 and improving the sleeving efficiency of the lifting appliance main body 10.

[0037] In one alternative embodiment, the flat shaft head provided in this embodiment is located at the upper end of the vertical roller.

[0038] In one alternative embodiment, the receiving cavity 11 provided in this embodiment is adapted to the structure of the flat shaft head.

[0039] See Figure 4 and Figure 7 As shown, in a specific embodiment, the flat shaft head has a connecting through hole, and the lifting body 10 has a first through hole 12 and a second through hole 13 on opposite sides. When the vertical roller connector 21 is in the first state, the first through hole 12 and the second through hole 13 are aligned with the connecting through hole, and the vertical roller connector 21 is sequentially inserted into the aligned first through hole 12, connecting through hole and second through hole 13 so that the lifting body 10 is connected to the flat shaft head. Setting the first through hole 12 and the second through hole 13 to align with the connecting through hole when the vertical roller connector 21 is in the first state simplifies the installation and alignment process between the lifting device body 10 and the flat shaft head, significantly shortens the assembly time of the vertical roller connector and the flat shaft head, and improves operational efficiency. At the same time, the vertical roller connector 21 passes through the aligned first through hole 12, connecting through hole and second through hole 13 in sequence, forming a multi-point mechanical lock, which avoids loosening of the connection due to vibration or load changes during the lifting process, ensuring a stable connection between the vertical roller connector and the flat shaft head. Furthermore, the design of aligning the first through hole 12 and the second through hole 13 with the connecting through hole makes the connection point between the lifting device body 10 and the flat shaft head bear force evenly, reduces local stress concentration, lowers the risk of structural deformation or breakage, and extends the service life of the vertical roller connector. The rigid connection mechanism between the vertical roller connector and the flat shaft head can effectively prevent accidental disengagement during the lifting process and improve operational safety.
