[0017] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0018] like Figures 1 to 12 As shown.

[0019] This application discloses a composite cushion layer clamping device for hoisting large floating wind turbines at offshore docks, comprising: The T-shaped cross slide rail and slide table device can only move forward and backward or left and right with the human hand-like pile holding device. It also includes a human-hand-like pile-holding device installed on a T-shaped cross rail and slide table via a telescopic arm mechanism. The human-hand-like pile-holding device is equipped with a vertical pulley control device that guides the pile foundation tower 23.

[0020] The T-shaped cross slide rail and slide table device includes a vertical slide rail 5, a horizontal slide rail 6, and a slide table 7. The vertical slide rail 5 and the horizontal slide rail 6 are fixed on the offshore operation carrier 22, and the vertical slide rail 5 and the horizontal slide rail 6 are vertically distributed. The slide table 7 is a double-layer assembly. The lower part of the slide table 7 is a guide key block 71 that cooperates with the limiting groove of the vertical slide rail 5. The guide key block 71 is used for guiding and limiting the vertical slide rail 5 in the left and right directions. The lower part of the slide table 7 is a bridging key block 72 that is flush with the rail surfaces at both ends of the horizontal slide rail 6. The cross section of the bridging key block 72 is consistent with the rail surface of the horizontal slide rail 6, and the width of the bridging key block 72 is equal to the rail width of the vertical slide rail 5. See [reference needed]. Figure 1 , Figure 10 The bridging key block 72 has four through holes, which are locked to the telescopic arm support 8 of the telescopic arm mechanism by means of pins 9, preventing interference. Figure 10 , Figure 11When the pin 9 is locked to the telescopic arm support 8, the telescopic arm support 8 can only move left and right on the vertical slide rail 5 via the bridging key block 72 of the slide table 7. At this time, the forward and backward movement of the telescopic arm support 8 is restricted. After the pin 9 is removed, the telescopic arm support 8 slides from the bridging key block 72 onto the horizontal slide rail 6 and moves forward and backward. At this time, the left and right movement of the telescopic arm support 8 is restricted. It can only move in one direction, either left or right or forward and backward, to prevent relative sliding due to inertia or wave interference.

[0021] The telescopic arm mechanism 2 includes a telescopic arm support 8, a primary telescopic arm 10, and a secondary telescopic arm 11. The primary telescopic arm 10 is fixedly connected to the top of the telescopic arm support 8, and the primary telescopic arm 10 and the secondary telescopic arm 11 can be linearly telescopically controlled.

[0022] The human-hand-like pile-holding device includes a primary pile-holding arm 12 fixed to a secondary telescopic arm 11. Secondary pile-holding arms 13 are rotatably hinged to both sides of the primary pile-holding arm 12 via pile-holding arm connecting rods 16. Tertiary pile-holding arms 14 are rotatably hinged to the secondary pile-holding arms 13 via pile-holding arm connecting rods 16. A fourth-level pile-holding arm 15 is rotatably hinged to the tertiary pile-holding arms 14 via pile-holding arm connecting rods 16, thus forming a multi-joint arm chain. This enables the device to grip and hold the pile foundation tower 23 with a variable curvature envelope, solving the problem of not being able to perform localized gripping based on the outer circumference shape of the pile foundation tower. The problem of gripping and clamping is addressed by changing the method. The four sets of primary pile-holding arm 12, secondary pile-holding arm 13, secondary pile-holding arm 13, tertiary pile-holding arm 14, and tertiary pile-holding arm 14 and quaternary pile-holding arm 15 are all connected by hydraulic telescopic connecting rods 17. The two ends of the hydraulic telescopic connecting rods 17 adopt a rotatable hinged connection structure. The hydraulic telescopic connecting rods 17 act as active actuators to adjust the angle between adjacent arm segments and provide clamping force. They can independently drive a single pile-holding arm to complete the opening and closing, or they can be paired or linked by a differential strategy to achieve encirclement and correction.

[0023] The inner sides of the first-level pile-holding arm 12, the second-level pile-holding arm 13, the third-level pile-holding arm 14, and the fourth-level pile-holding arm 15 are all fixed with a composite pad 18 to provide cushioning, reducing the risk of damage to the tower base material and anti-corrosion coating.

[0024] The vertical pulley control device includes multiple pulley control consoles 21 fixed to the top of the first-stage pile-holding arm 12, the second-stage pile-holding arm 13, the third-stage pile-holding arm 14, and the fourth-stage pile-holding arm 15. Pulley arms 20 are rotatably hinged to the pulley control consoles 21. The pulley arms 20 are mounted on the pulley control consoles 21 by torsion springs, causing the pulley arms 20 to retract inwards. Pulleys 19 are rotatably mounted on the pulley arms 20. The pulleys 19 can roll and rotate on the pulley arms 20 and can contact the outer periphery of the pile foundation tower 23.
