Description

Technical Field

[0001] This utility model relates to wind power operation and maintenance equipment, and in particular to a lifting wave compensation trestle. Background Technology

[0002] When replenishment vessels operate at sea, they are subject to significant swaying due to wind, waves, and tides. When replenishment vessels provide services to offshore wind power plants or fixed platforms, they are constantly in a state of heave and swaying, posing a great risk to personnel working at sea and during transfers. Safe and stable docking of replenishment vessels with platforms is a very important safeguard to ensure the safety of personnel working at sea and during transfers.

[0003] In existing technologies, active wave compensation can be achieved by using trestle docks with wave compensation features. However, due to the significant height difference between the supply vessel and the offshore wind turbine or fixed platform, the wave compensation trestle can only be docked by increasing the pitch angle of the trestle. There are still significant safety hazards for personnel walking on the trestle with a large slope, especially in rainy or snowy weather. Furthermore, the wave compensation process requires frequent angle adjustments, making the operation complicated and the docking efficiency low.

[0004] It is evident that existing technologies suffer from low docking efficiency and significant safety risks when connecting trestle bridges with floating bodies or fixed platforms at sea. Utility Model Content

[0005] This invention provides a lifting wave-compensating pier, which solves the problems of low docking efficiency and high safety risks of existing piers with floating bodies and fixed platforms at sea.

[0009] This invention utilizes a lifting assembly to allow the pier to adjust its height according to real-time sea conditions, maintaining a relatively horizontal position between the pier and the operating platform of the floating body or fixed platform. This avoids personnel having to walk on piers with steep inclines, reducing safety hazards during offshore operations.

[0017] The trestle assembly is installed on the surface of the compensation platform away from the lifting assembly to follow the swing of the compensation platform.

[0018] This embodiment of the invention utilizes multiple drive cylinders supported between a compensation platform and a lifting platform to adjust the tilt angle of the compensation platform relative to the horizontal plane, thereby compensating for the impact of ocean waves and ensuring that the compensation platform remains relatively level.

The wave compensation assembly 12 is used to drive the trestle assembly 13 to swing around the wave compensation assembly, so that at least a portion of the trestle assembly 13 is parallel to the horizontal plane.

[0047] The lifting assembly includes a tower 110, a lifting winch 111, a lifting rail 112, and a lifting platform 113. The tower 110 is erected on the deck of the ship, the lifting winch 111 is located on the top of the tower 110, the side wall of the tower 110 is provided with the lifting rail 112, and the side wall of the lifting platform 113 is slidably connected to the lifting rail 112 and can be raised and lowered along the lifting rail 112 under the drive of the lifting winch 111.

This ensures the pier remains relatively level with the operating platform of the floating body or fixed platform, preventing personnel from walking on steep piers and reducing safety hazards during offshore operations. Furthermore, the lifting assembly of this invention, using the cooperation of the tower 110, lifting winch 111, lifting rail 112, and lifting platform 113, ensures smooth and rapid lifting, improving the efficiency of docking the pier with the floating body or fixed platform.

[0056] The compensation platform 121 and the lifting platform 113 are arranged facing each other.

[0057] In one embodiment, the wave compensation assembly 12 further includes a platform base 120, which is mounted on the top surface of the lifting platform 113 and is positioned face-to-face with the compensation platform 121. Multiple drive cylinders are supported on the lifting platform 113 via the platform base 120.

[0058] This embodiment of the invention utilizes multiple drive cylinders supported between the compensation platform 121 and the lifting platform 113 to adjust the tilt angle of the compensation platform 121 relative to the horizontal plane, thereby compensating for the impact of ocean waves and ensuring that the compensation platform 121 remains in a relatively horizontal state. The staggered arrangement of at least some of the drive cylinders enhances the stability of the compensation platform 121 during tilt adjustment, preventing violent shaking of the compensation platform 121.

The trestle main body 130 is connected to the top end of the cylindrical body 134 and forms a T-shaped structure. The rotation drive unit 135 is used to drive the cylindrical body 134 and the trestle main body 130 to rotate about the rotation axis of the cylindrical body 134. The rotation axis of the cylindrical body 134 can be, for example, the axis of rotation of the cylindrical body 134.

[0067] Furthermore, in one embodiment, the trestle assembly 13 further includes a base 136, which is rotatably connected to the wave compensation assembly 12, for example, rotatably connected to the compensation platform 121.

The first end of the telescopic rod 137 is connected to the side wall of the cylinder 134, and the second end of the telescopic rod 137 is connected to the non-end portion of the second trestle section 132 (which can be understood as the portion of the second trestle section 132 other than the end portion), so that the second trestle section 132 moves around the first end of the first trestle section 131 in a direction closer to or further away from the cylinder 134 under the drive of the telescopic rod 137. In one embodiment, the first end of the second trestle section 132 is rotatably connected to the first end of the first trestle section 131 via a pivot 1301. The first trestle section 131 can serve as a waiting platform for operators to stand and wait for the lifting wave-compensating trestle of this embodiment to be properly adjusted.

The telescopic gear 138 can be driven, for example, by an electric motor, a hydraulic motor, or a cylinder. In other alternative embodiments, it can also be manually driven by a rocker arm.

[0071] This utility model embodiment uses telescopic gear 138 and telescopic rack 139 to allow the telescopic trestle section 133 to extend or retract relative to the second trestle section 132, making the length of the trestle flexible and adaptable, further improving the flexibility of trestle operations at sea and enriching the application scenarios of the lifting wave compensation trestle 1.
