[0002] With the development of my country's marine energy development, port-related industries, and marine economy, the assembly and shipment of wind turbines for offshore wind power plants, the shipment of pile foundations, large prefabricated components, and equipment for offshore bridges, submarine passages, port projects, and offshore oil and gas platforms, and the entry and exit of large-scale production equipment for port-related industries have led to the loading and unloading of increasingly large marine engineering equipment, weighing hundreds or even thousands of tons. Gantry cranes installed on conventional freight terminals are unable to lift large marine equipment. To address the loading and unloading of heavy equipment, SPMT self-propelled hydraulic flatbed trucks can also be used. However, this method suffers from the impact of tide levels on short operation times and low efficiency. Therefore, to meet the lifting needs of large components in marine equipment projects, a new type of gantry wharf with good applicability, economic rationality, and high efficiency has been proposed to better serve the development of the marine economy. Summary of the Invention

[0016] The following is a detailed introduction to the present invention in conjunction with the accompanying drawings: Figures 1 to 3 As shown, the utility model includes an approach bridge 2, a dock approach bridge 1 and a gantry crane 3. The approach bridge 2 and the dock approach bridge 1 are arranged in parallel, and an empty water space 10 is left between the two for ships to berth. The width of the empty water space 10 is determined by the span of the gantry crane 3, the width of the berthed ship, hydrological conditions, ship operation, etc.; the approach bridge 2 and the dock approach bridge 1 are both arranged on the seawall coastline 12 side of the land yard 11, and the platform axes of the approach bridge 2 and the dock approach bridge 1 are arranged perpendicular to the seawall coastline 12; double-track tracks 4 are installed on the approach bridge 2 and the land yard 11 and the dock approach bridge 1 and the land yard 11. The gantry crane 3 spans the empty water space 10 and is installed on the double-track tracks 4. Two gantry cranes 3 are provided and are symmetrically distributed along the length direction of the approach bridge 2, and the gantry crane 3 slides along the double-track tracks 4 to realize the lifting of large components on the ship. The wharf approach bridge 1 and approach bridge 2 adopt high-pile beam-slab structure. The wharf approach bridge 1 on the ship side is designed as a wide platform for berthing the wharf and traveling the gantry crane, while the approach bridge 2 is designed as a narrow platform only as the traveling base of the gantry crane.

[0017] Different from the shore-side wharf, when a ship berths at the gantry wharf, it turns in front of the wharf and sails slowly to the gantry port. The ship slowly enters the gear and berths along the side platform of the wharf, which makes ship maneuvering difficult. Therefore, reinforced end piers 13 are provided at the sea-surface ends of the approach bridge 2 and the wharf approach bridge 1. The reinforced end piers 13 are provided with double-track tracks 4 and are connected to the double-track tracks 4 on the approach bridge 2 and the wharf approach bridge 1.

[0018] The reinforced end pier 13 is a high pile pier structure, including inclined piles 13-1 and a bearing platform 13-2. The inclined piles 13-1 are provided with a plurality of and fixed on the seabed. The bearing platform 13-2 is integrally cast on the inclined piles 13-1, and the surface of the bearing platform 13-2 is flush with the bridge deck of the approach bridge 2 and the wharf approach bridge 1, and the width of the bearing platform 13-2 is flush with the width of the approach bridge 2 and the wharf approach bridge 1.

[0019] Both end corners of the supporting platform 13-2 are set to be chamfered. A rotating three-wheel rubber fender 6 is installed on the end corner of the supporting platform 13-2 close to the empty water space 10, and a drum-type rubber fender 7 is installed on the inner side of the supporting platform 13-2, and the drum-type rubber fender 7 is located on the side of the empty water space 10.

[0020] A solar lamp post 9 is installed on the surface of the supporting platform 13 - 2 , and the solar lamp post 9 is located outside the supporting platform 13 - 2 .

[0021] Arched rubber fenders 8 are installed on the inner sides of the approach bridge 2 and the pier approach bridge 1, and the arched rubber fenders 8 are located on the side of the vacant water space 10.

[0022] A mooring post 5 and an electric winch drum 14 are installed on the deck of the dock approach bridge 1. The mooring post 5 is located near the inner side of the dock approach bridge 1, while the electric winch drum 14 is located near the outer side of the dock approach bridge 1. Ships frequently berth and shift positions at the port, which requires a large pulling force on the cable. The electric winch drum 14 is used to secure the cable to the mooring bollard on the dock, completing the mooring process.

[0023] The rotating three-wheeled rubber fender 6 utilizes the rotation and compression deformation of the rollers (rubber) to absorb ship impact energy. When a ship is berthing or moving, the rotating three-wheeled rubber fender 6 adapts to the movement of the hull and rotates, thereby ensuring the safety of the dock and ship. The fender (rollers) rotate on three axes, limiting and reducing the ship's speed, facilitating safe berthing. The rotating three-wheeled rubber fender 6 is suitable for applications requiring limited ship movement and berthing speed.

[0024] The drum-type rubber fender 7 is in a drum-shaped state after compression deformation. Among the compression-type fender series, the fender has high energy absorption per unit weight and is particularly suitable for pier-type docks. An anti-collision steel frame is provided at the leading edge of the fender, thereby greatly reducing the surface pressure acting on the ship's side plate. A PE veneer is installed in front of the anti-collision steel frame to reduce the friction coefficient and greatly reduce the berthing shear force.

[0025] The arched rubber fender 8 has many advantages such as high energy absorption, flexible layout, suitable installation size, etc. Its unit product weight energy absorption is second only to the super drum fender among compression type fenders.

[0026] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
