[0026] This utility model provides a rolling mill flattening roll assembly / disassembly platform, including a support platform 1 with support legs 2 underneath. A fixing frame 3 extends upward from the support platform 1, and a lifting ring 5 is equipped at the top of the fixing frame 3. The lifting ring 5 is connected to a trolley via a chain, facilitating adjustment of the platform's height and position. A transverse frame 4 is connected to the fixing frame 3 and has connecting holes 6 for installing a winch 7. The winch 7 refers to a type of special lifting equipment, including hand-cranked winches and electric winches. A component specifically for fixing the flattening roll is installed at the end of the winch 7.

[0027] The flattening roller fixing component includes a first arc plate 7 and a second arc plate 8, which are detachably connected by a first knob bolt 10. The ends of the first arc plate 4 and the second arc plate 5 extend and are rotatably connected. The contact surfaces of the two arc plates are also provided with elastic clamping blocks 11 to ensure the stability of the flattening roller during disassembly, assembly, and hoisting.

[0028] To enhance operational safety, the support platform 1 is surrounded by a protective fence 12, which has a hinged door 13. One side of the door 13 is equipped with a latch 14, which can be inserted into a pre-set latch interface 15 of the protective fence 12 to prevent accidental opening.
