[0024] Specifically, by starting the motor 4, the bidirectional screw rod 6 will be driven to rotate; at this time, the bidirectional screw rod 6 is meshed with the threaded sleeve 13, so that the threaded sleeve 13 is limited and slid on the inner wall of the limiting groove 2; thereby avoiding operational errors caused by movement deviation; as the threaded sleeve 13 slides, the fixed block three 11 on the outer wall of the fixed rod 12 also slides; the fixed block three 11 serves as a bridge connecting the threaded sleeve 13 and the fixed rod 12, and plays a role in transmitting power; driven by the fixed block three 11, the fixed rod 12 begins to move; the movement of the fixed rod 12 further drives the rotation of the rotating plate 14; through the movement of the rotating plate 14, the rotation adjustment of the arc frame 9 and the rotating roller 10 can be achieved; this adjustment function enables the device to adapt to the travel requirements of steel materials of different heights, and improves the flexibility and applicability of the equipment; in addition, the movement of the fixed rod 12 also drives the sliding of the inside of the fixed frame 1503 and the support plate 1501; thereby achieving the effect of the fixed frame 1503 and the support plate 1501 lifting the rotating roller 1502.

[0026] Specifically, when the electric push rod 17 is started to push the stabilizing plate 18 to move, and the stabilizing plate 18 drives the second connecting plate 21 to rotate, after the second connecting plate 21 is driven by the stabilizing plate 18, the rotation of the second connecting plate 21 effectively drives the first connecting plate 20 to cross-move inside the bracket 19; with the coordinated movement of the second connecting plate 21 and the first connecting plate 20, the limiting rod 22 also begins to play its key role; the limiting rod 22 is cleverly designed to connect with the second connecting plate 21 and the first connecting plate 20, and through their movement, the limiting rod 22 can accurately drive the anti-locking device 19 to move.

[0027] Working principle: when the steel plate needs to be supported to prevent it from mopping the floor, the motor 4 is started, and the bidirectional screw rod 6 is driven to rotate by the motor 4, and the threaded sleeve 13 is driven to slide on the inner wall of the limiting groove 2 by the bidirectional screw rod 6, and the fixed block 11 on the outer wall of the fixed rod 12 is driven to slide by the threaded sleeve 13, and the rotating plate 14 is driven to rotate by the movement of the fixed rod 12, and the rotating roller 10 is driven to rotate and adjust by the movement of the rotating plate 14, and the fixed frame 1503 is driven to slide inside the support plate 1501 by the movement of the fixed rod 12, so as to facilitate the driving of the roller 1502 to support the steel material to lift and prevent mopping the floor;

[0028] Secondly, when the ferry device needs to be repaired after being used for a long time, the stabilizing plate 18 is started to drive the connecting plate 21 to rotate. The movement of the connecting plate 21 drives the connecting plate 1 20 to cross-move inside the bracket 19. The movement of the connecting plate 21 and the connecting plate 1 20 drives the limiting rod 22 to drive the guardrail 23.
