[0002] Coil, as an important form of steel product, is widely used in many fields such as construction, machinery, and automobiles. Its characteristic is that the diameter is less than a certain size (such as the common 10mm and below), usually in the form of hot-rolled steel or rebar, and is automatically rolled into a coil after rolling to facilitate subsequent transportation and use. However, in the production process of steel mills, there are a series of technical problems in the production and transportation of coils that need to be solved urgently.

[0003] In the coil production process, after a series of processes such as heating and rolling, the wire is rolled into the required specifications. However, when these wires are transferred from the production process to the transportation process, they face significant problems such as complex transfer equipment and large space occupied. Traditional transfer methods often rely on bulky mechanical equipment and complicated operating procedures, which not only increases production costs but also reduces production efficiency.

[0004] Specifically, existing transfer equipment is often complex in design, containing multiple mechanical parts and transmission devices, which leads to increased equipment maintenance costs and increased failure rates. At the same time, due to the large size and weight of the coil, the traditional transfer method often requires a large space, which is undoubtedly a huge challenge for steel mills with limited space resources.

The flip seat 5 is slidably connected to the lifting support frame 2, and the lifting support frame 2 is used as a guide device for the lifting and moving of the flip seat 5 to ensure the stability of the lifting and moving of the flip seat 5. The flip seat 5 is connected to a lifting drive mechanism 6, and the lifting drive mechanism 6 is used to provide power for the lifting and moving of the flip seat 5. The lifting drive mechanism 6 can adopt a screw nut structure, a hydraulic cylinder / cylinder telescopic structure, etc. The flip frame 3 includes a bottom beam 31 and a support arm 32.

The end of the support arm 32 is connected to the bottom beam 31, and the two form a T-shape, that is, when the bottom beam 31 is in a horizontal state, the support arm 32 is in a vertical state, and vice versa, when the bottom beam 31 is in a vertical state, the support arm 32 is in a horizontal state.

When the first hydraulic cylinder and the second hydraulic cylinder are synchronously extended and retracted, the turning frame 3 and the turning seat 5 are synchronously lifted and lowered. When the movement amplitude of the second hydraulic cylinder is greater than that of the first hydraulic cylinder, the turning frame 3 can be turned relative to the turning seat 5.

In addition, the tilting brace 23 may include two groups, the tilting brace 23 is connected to the corresponding vertical beam 21 and the horizontal beam 11, and there is a space between the tilting brace 23 for the turning frame 3 to rotate. At least one second connecting beam 12 is provided at the position where the horizontal beam 11 connects the tilting brace 23 to further enhance the stability of the overall structure.

[0061] S3, raising the turning frame 3, sending the support arm 32 into the inner diameter side of the coil 8, until the bottom beam 31 contacts the coil 8, at which time the coil 8 is located on the first bearing surface 311;

[0062] S4, rotating the turning frame 3. It should be noted that before rotating the turning frame 3, the traveling frame 1 can be further moved until the second bearing surface 321 of the support arm 32 is in contact with the inner diameter side of the coil 8.

[0074] ⑥ The traveling frame 1 moves toward the C-hook hanger of the accumulation and release conveyor line. During the movement, it descends a certain height, that is, the two actions are performed simultaneously. When the traveling frame 1 moves to position ⑥, the turning frame 3 has already descended to its position. It should be noted that the turning frame 3 may not stop at position ⑥, but continue to move;

[0075] ⑦ The traveling frame 1 moves to the C-hook sling of the accumulation and release conveyor line, and allows the C-hook 7 to penetrate the inner diameter side of the coil 8;

[0076] ⑧ The turning frame 3 is lowered to a certain height to transfer the coil 8 to the C-shaped hook 7;

[0077] ⑨ After the walking frame 1 runs in the reverse direction to position ⑨, it flips 90° in the reverse direction to reset, and descends, and continues to walk to position ① to perform the next flipping and transporting cycle.
