Description

Technical Field

[0001] The present invention belongs to the technical field of ships, and more particularly, relates to a ship transfer bridge structure. Background Art

[0002] The need for transfer bridge technology to overcome freeboard differences stems from the problem of freeboard height fluctuations caused by vessel load, tidal fluctuations, or differences in ship types during traditional port loading and unloading operations. Traditional fixed ramps or manually adjustable devices struggle to adapt to the dynamically changing gap between the ship and the dock, often leading to low loading and unloading efficiency, increased safety hazards, and increased equipment wear. Particularly in ports with significant tidal ranges or frequent changes in ship types, operators must repeatedly adjust the ramp's angle and height, which is time-consuming and labor-intensive, and poses a risk of falls. Early solutions relied on mechanical lifting platforms or segmented ramps, but these suffered from low adjustment accuracy, slow response speed, and insufficient structural stability. Specifically, these existing technologies rely on manual operation, resulting in a time-consuming and inaccurate adjustment process. Dynamic compensation is particularly difficult to achieve in scenarios with frequent tidal fluctuations or large differences in ship types, leading to low loading and unloading efficiency. For example, anchoring techniques can cause stability issues due to anchor chain entanglement or scratches on the ship's bottom, further complicating adjustment. Common defects in the welding process, such as pores, slag inclusions, or incomplete penetration (e.g., substandard weld quality), can weaken the structural strength of the transfer bridge and easily cause fatigue damage after long-term use, affecting safety and service life. In addition, salt spray corrosion and wind and wave impacts in the offshore environment accelerate material aging, leading to increased maintenance costs. The structures in existing technologies are not sufficiently responsive to dynamic environmental factors such as wind, waves, and tides. Offshore lifting operations need to cope with surge disturbances, and traditional manual positioning systems are difficult to achieve dynamic correction, resulting in increased installation errors and even safety risks.

[0003] The prior art includes a technology entitled "A High-bulwark Ship Dock Boarding Ladder" and a publication (announcement) number of "CN117536537A", which discloses a high-bulwark ship dock boarding ladder comprising a base, an adjustment device, a sliding device, and a cleaning device; the adjustment device comprises a support block fixedly connected to the top of the base, an upper ladder frame rotatably connected to the surface of the support block, an upper step rotatably connected to the inner wall of the upper ladder frame, a lower ladder frame slidably connected to the bottom of the upper ladder frame, a lower step rotatably connected to the inner wall of the lower ladder frame, a hydraulic cylinder fixedly connected to the top of the base, and a fixed rod fixedly connected to the inner wall of the lower ladder frame; the sliding device comprises an upper telescopic rod fixedly connected to the bottom of the upper step, a lower telescopic rod fixedly connected to the bottom of the lower step, and two pairs of transmission rods rotatably connected to the plurality of upper steps and the lower step, respectively; the present invention has the characteristics of strong practicality and a low height difference between the boarding ladder and the hull.

[0004] However, this technology does not involve the technical problems and technical solutions of the present application. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: in view of the shortcomings of the existing technology, a ship transfer bridge structure with a simple structure is provided, which has high adaptability and adjustment flexibility when the transfer bridge is arranged between the ship and the dock, and effectively ensures the layout reliability and traffic safety.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is:

[0007] The present invention is a ship transfer bridge structure, comprising a plurality of transfer bridge supports and a plurality of transfer bridge passage surfaces. The transfer bridge supports are frame structures, and each transfer bridge passage surface comprises a first connecting shaft and a second connecting shaft. The first connecting shaft is movably connected to one transfer bridge support, and the second connecting shaft is movably connected to another transfer bridge support. A plurality of telescopic spiral members are connected between the first connecting shaft and the second connecting shaft, and the connected telescopic spiral members are connected by connecting short rods, or a plurality of fixed rod members are connected between the first connecting shaft and the second connecting shaft, and the connected fixed rod members are connected by connecting short rods.

[0008] The transfer bridge bracket close to the wharf is movably connected to the transfer bridge gangway.

[0009] A reel is installed on the transfer bridge bracket close to the wharf, a reel motor is installed on the reel, and the reel on the reel is connected to the transfer bridge gangway.

[0010] The dock pile foundation is fixed in the embedded hole of the dock, and the ship pile foundation is set on the ship. The dock pile foundation is set as a structure that can be fixedly connected to the transfer bridge gangway, and the ship pile foundation is set as a structure that can be fixedly connected to the transfer bridge bracket.

[0011] The transfer bridge passage surface includes a rigid transfer bridge passage surface and a flexible transfer bridge passage surface, and the ship transfer bridge structure includes multiple rigid transfer bridge passage surfaces and multiple flexible transfer bridge passage surfaces.

[0012] Each rigid transfer bridge passage surface is connected to a transfer bridge bracket respectively, and the flexible transfer bridge passage surface is located between the rigid transfer bridge passage surface and the transfer bridge gangway.

[0013] The rigid transfer bridge passage surface includes a first connecting shaft and a second connecting shaft. The first connecting shaft is movably connected to one transfer bridge bracket, and the second connecting shaft is movably connected to another transfer bridge bracket. Multiple fixed rods are connected between the first connecting shaft and the second connecting shaft, and the connected fixed rods are connected by connecting short rods.

[0014] The flexible transfer bridge passage surface includes a first connecting shaft and a second connecting shaft. The first connecting shaft is movably connected to one transfer bridge bracket, and the second connecting shaft is movably connected to another transfer bridge bracket. Multiple telescopic spiral members are connected between the first connecting shaft and the second connecting shaft, and the connected telescopic spiral members are connected by a connecting short rod.

[0015] A buffer block is provided on the side of the dock close to the water surface.

[0016] The transfer bridge support close to the wharf is connected to the wharf pile foundation through a fixing rope.

[0017] The technical solution of the present invention is adopted, and the working principle and beneficial effects are as follows:

[0018] The ship transfer bridge structure described in the present invention is assembled to form a ship transfer bridge structure based on the need to establish a passageway between a ship and a dock. The ship transfer bridge structure includes multiple transfer bridge supports and multiple transfer bridge passageways. The transfer bridge supports are framework structures that serve as the foundation for connecting the transfer bridge passageways, ensuring that multiple short transfer bridge passageways can be combined to form a long ship transfer bridge structure. Each transfer bridge passageway includes a first connecting shaft and a second connecting shaft. The first connecting shaft flexibly connects to one transfer bridge support, and the second connecting shaft flexibly connects to another transfer bridge support. In this way, each transfer bridge passageway is flexibly connected to its corresponding transfer bridge support. Because the ship transfer bridge structure needs to accommodate different angles between the ship and the dock, such as 45°, 90°, and 0°, two types of transfer bridge passageways are required: a rigid transfer bridge passageway and a flexible transfer bridge passageway. The flexible transfer bridge passageway can be adjusted in angle, thereby adjusting the bending angle of the entire ship transfer bridge structure. As a flexible transfer bridge passage surface, multiple telescopic spirals are connected between the first connecting shaft and the second connecting shaft. The telescopic spirals have the tensile properties of bending, elongation and shortening, which can change the angle of the entire flexible transfer bridge passage surface. The connected telescopic spirals are connected by connecting short rods to ensure that different telescopic spirals are reliably connected, forming a passage surface that can ensure the passage of personnel. As a rigid transfer bridge passage surface, multiple fixed rods are connected between the first connecting shaft and the second connecting shaft. The fixed rods are structurally fixed rod structures. The connected fixed rods are connected by connecting short rods to realize a rigid transfer bridge passage surface with an overall frame structure, which is convenient for the passage of personnel. The transfer bridge passage surface and the transfer bridge bracket are movably connected. The flexible transfer bridge passage surface can be bent and set to structures with different angles, so that the ship transfer bridge structure is a flexible structure when arranged between the ship and the dock, effectively ensuring high adaptability and adjustment flexibility, and can effectively cope with the influence of dynamic environmental factors such as wind, waves, and tides to ensure the passage of personnel.

[0020] The following describes the embodiments with reference to the accompanying drawings to further explain in detail the specific embodiments of the present invention, such as the shapes, structures, mutual positions and connection relationships between the various components involved, the functions and working principles of the various components.

[0021] As attached Figure 1 -Attached Figure 8As shown, the present invention is a ship transfer bridge structure, including a plurality of transfer bridge brackets 1 and a plurality of transfer bridge passage surfaces 2. The transfer bridge bracket 1 is a frame structure, and each transfer bridge passage surface 2 includes a first connecting shaft 3 and a second connecting shaft 4. The first connecting shaft 3 is movably connected to one transfer bridge bracket 1, and the second connecting shaft 4 is movably connected to another transfer bridge bracket 1. A plurality of telescopic spiral members 5 are connected between the first connecting shaft 3 and the second connecting shaft 4, and the connected telescopic spiral members 5 are connected by a connecting short rod 6, or a plurality of fixed rod members 7 are connected between the first connecting shaft 3 and the second connecting shaft 4, and the connected fixed rod members 7 are connected by a connecting short rod 6. The above structure proposes an improved technical solution to address the deficiencies in the prior art. When the structure is set up, it is combined to form a ship transfer bridge structure according to the need to establish a passage between the ship and the dock. The ship transfer bridge structure includes multiple transfer bridge brackets 1 and multiple transfer bridge passages 2. The transfer bridge bracket 1 is a frame structure and is the basis for connecting the transfer bridge passages 2, ensuring that multiple short-sized transfer bridge passages 2 are combined to form a long-sized ship transfer bridge structure. Each transfer bridge passage 2 includes a first connecting shaft 3 and a second connecting shaft 4. The first connecting shaft 3 is movably connected to one transfer bridge bracket 1, and the second connecting shaft 4 is movably connected to another transfer bridge bracket 1; in this way, each transfer bridge passage 2 is movably connected to the corresponding transfer bridge bracket 1. Because it is necessary to adapt to the different angles of arrangement of the ship transfer bridge structure between the ship and the dock, for example, 45°, 90°, 0°, etc., two types of transfer bridge passages 2 need to be set: one is a rigid transfer bridge passage, and the other is a flexible transfer bridge passage. In this way, the flexible transfer bridge passage can achieve angle changes, thereby adjusting the bending angle of the entire ship transfer bridge structure. As a flexible transfer bridge passage surface, when it is set up, multiple telescopic screws 5 are connected between the first connecting shaft 3 and the second connecting shaft 4. The telescopic screws 5 have the tensile properties of bending, elongation and shortening, so that the angle of the entire flexible transfer bridge passage surface can be changed. The connected telescopic screws 5 are connected by connecting short rods 6 to ensure that the different telescopic screws 5 are reliably connected, forming a passage surface that can ensure the passage of people. As a rigid transfer bridge passage surface, multiple fixed rods 7 are connected between the first connecting shaft 3 and the second connecting shaft 4. The fixed rods 7 are structurally fixed rod structures. The connected fixed rods 7 are connected by connecting short rods 6 to realize a rigid transfer bridge passage surface with an overall frame structure, which is convenient for people to pass. In this way, the transfer bridge passage surface 2 and the transfer bridge bracket 1 are movably connected, and the flexible transfer bridge passage surface 2 can be bent and set to a structure with different angles, so that the ship transfer bridge structure is a flexible structure when arranged between the ship and the dock, effectively ensuring high adaptability and adjustment flexibility, and being able to effectively cope with the influence of dynamic environmental factors such as wind, waves, and tides, to ensure the passage of people. The ship transfer bridge structure of the present invention has a simple structure. When the transfer bridge is arranged between the ship and the dock, it has high adaptability and adjustment flexibility, effectively ensuring the reliability of the arrangement and the safety of traffic.

[0022] The transfer bridge bracket 1 near the dock 9 is flexibly connected to the transfer bridge gangway 10. In this structure, the transfer bridge gangway 10 is used to dock at the dock and simultaneously connects to the corresponding transfer bridge bracket 1, extending from the ship to the dock and facilitating the passage of personnel. Furthermore, the non-rigid connection between the transfer bridge bracket 1 and the transfer bridge gangway ensures reliable docking in wind, waves, and tides.

[0023] The transfer bridge support 1 near the dock 9 is equipped with a reel, which is equipped with a reel motor. The reel 11 is connected to the transfer bridge gangway 10. With this structure, when the transfer bridge gangway is docked at the dock, the reel motor is controlled to release the reel 11, ensuring that the transfer bridge gangway 10 is docked securely. The reel 11 also acts as a pull and restraint on the transfer bridge gangway.

[0024] A dock pile foundation 17 is fixedly installed in the pre-buried hole of the dock 9, and a ship pile foundation is installed on the ship 15. The dock pile foundation 17 is configured to be fixedly connected to the transfer bridge gangway 10, and the ship pile foundation is configured to be fixedly connected to the transfer bridge support 1. With this structure, the dock pile foundation 17 can be connected to the transfer bridge gangway 10 via a fixed rope, achieving flexible restraint of the transfer bridge gangway 10. The ship pile foundation can also be connected to the transfer bridge support 1 via a fixed rope, achieving flexible restraint of the transfer bridge support 1, ensuring that the transfer bridge structure is securely anchored between the ship and the dock.

[0025] The transfer bridge passage 2 comprises a rigid transfer bridge passage 12 and a flexible transfer bridge passage 13. The ship transfer bridge structure comprises multiple rigid transfer bridge passages 12 and multiple flexible transfer bridge passages 13. Each rigid transfer bridge passage 12 is connected to the transfer bridge support 1, while the flexible transfer bridge passage 13 is located between the rigid transfer bridge passage 12 and the transfer bridge gangway 10. In this structure, the rigid transfer bridge passage 12 is a flexible structure, allowing for reliable installation on a ship, while the flexible transfer bridge passage 13 is a flexible structure that can be bent at a certain angle, allowing for reliable deployment at various angles required by the transfer bridge structure.

[0026] The rigid transfer bridge passage 12 includes a first connecting shaft 3 and a second connecting shaft 4. The first connecting shaft 3 is movably connected to one transfer bridge bracket 1, and the second connecting shaft 4 is movably connected to another transfer bridge bracket 1. Multiple fixed rods 7 are connected between the first and second connecting shafts 3 and 4. The connected fixed rods 7 are connected by short connecting rods 6. The above structure forms a reliable rigid transfer bridge passage 12, which facilitates the passage of personnel between ships and docks.

[0027] The flexible transfer bridge passage surface 13 comprises a first connecting shaft 3 and a second connecting shaft 4. The first connecting shaft 3 is movably connected to one transfer bridge bracket 1, and the second connecting shaft 4 is movably connected to another transfer bridge bracket 1. Multiple telescopic spiral members 5 are connected between the first and second connecting shafts 3 and 4. These connected telescopic spiral members 5 are connected by a connecting short rod 6. This structure forms a reliable flexible transfer bridge passage surface 12, which can be easily bent to adjust the angle of the structure after arrangement.

[0028] The pier 9 is provided with a buffer block 8 on one side close to the water surface 14. In the above structure, a plurality of buffer blocks 8 are provided, which are made of rubber material to avoid rigid collision when the ship is docked.

[0029] The transfer bridge support 1 near the pier 9 is connected to the pier pile foundation 17 via a fixing rope 16. In the above structure, the transfer bridge support 1 is connected via the fixing rope 16 to achieve reliable fixation.

[0030] The ship transfer bridge structure described in the present invention is combined to form a ship transfer bridge structure based on the need to establish a passage between a ship and a dock. The ship transfer bridge structure includes multiple transfer bridge supports 1 and multiple transfer bridge passage surfaces 2. The transfer bridge supports 1 are frame structures that serve as the foundation for connecting the transfer bridge passage surfaces 2, ensuring that multiple short-sized transfer bridge passage surfaces 2 are combined to form a long-sized ship transfer bridge structure. Each transfer bridge passage surface 2 includes a first connecting shaft 3 and a second connecting shaft 4. The first connecting shaft 3 is movably connected to one transfer bridge support 1, and the second connecting shaft 4 is movably connected to another transfer bridge support 1. In this way, each transfer bridge passage surface 2 is movably connected to the corresponding transfer bridge support 1. Because the ship transfer bridge structure needs to be arranged at different angles between the ship and the dock, such as 45°, 90°, and 0°, the transfer bridge passage surfaces 2 can be either rigid or flexible. In this way, the flexible transfer bridge passage surface can achieve angle changes, thereby adjusting the bending angle of the entire ship transfer bridge structure. As a flexible transfer bridge passage surface, when set, multiple telescopic screws 5 are connected between the first connecting shaft 3 and the second connecting shaft 4. The telescopic screws 5 have tensile properties of bending, elongation and shortening, thereby changing the angle of the entire flexible transfer bridge passage surface. The connected telescopic screws 5 are connected by connecting short rods 6 to ensure that different telescopic screws 5 are reliably connected to form a passage surface that can ensure the passage of personnel. As a rigid transfer bridge passage surface, multiple fixed rods 7 are connected between the first connecting shaft 3 and the second connecting shaft 4. The fixed rods 7 are structurally fixed rod structures. The connected fixed rods 7 are connected by connecting short rods 6 to achieve a rigid transfer bridge passage surface with a frame structure as a whole, which is convenient for the passage of personnel. In this way, the transfer bridge passage surface 2 and the transfer bridge bracket 1 are movably connected, and the flexible transfer bridge passage surface 2 can be bent and set to structures with different angles, so that the ship transfer bridge structure is a flexible structure when arranged between the ship and the dock, effectively ensuring high adaptability and adjustment flexibility, and being able to effectively cope with the influence of dynamic environmental factors such as wind, waves, and tides, and ensure the passage of personnel.

[0031] The ship transfer bridge structure described in the present invention is a flexible connection structure as a whole, which can form a dynamic compensation and multi-degree-of-freedom adjustment mechanism, realize real-time compensation for ship swaying (such as vertical displacement caused by waves), and ensure the stable docking of the transfer bridge under different freeboard differences. The design of the flexible connection structure allows flexible adjustment of the length and angle of the bridge body to meet the connection requirements of different distances and height differences. The transfer bridge bracket 1 and the transfer bridge passage 2 are flexibly connected, and the coaxial rotation of the components is achieved through the connecting shaft, which is convenient for rapid installation and disassembly, while reducing the dependence on large lifting equipment. Enhanced safety and stability: The bridge deck of the transfer bridge passage 2 is provided with anti-slip grooves and guardrails, combined with anti-corrosion coatings and lighting to ensure the safety of operators. Fixing and sealing technology: It is tightly connected to the pile foundation through pre-buried holes to ensure the stability of the bridge in complex environments. Intelligent and automated control: motor drive and wire drum retraction: The motor is used to drive the wire drum to retract and release the wire rope to realize automatic lifting and lowering of the bridge body, reduce manual intervention, and improve efficiency. When the entire structure is transported, the transportation is achieved by a crane. The structure adopts lightweight and high-strength materials: it reduces weight while ensuring strength, and is suitable for marine environments. The detachable fixing device supports reuse, reduces costs, and is suitable for temporary bridge construction. In summary, the ship transfer bridge structure described in the present invention has 1. High adaptability and adjustment flexibility: the transfer bridge can adapt to a wide range of freeboard differences through independent or combined control of the three actions of lifting, flipping and translation. This multi-degree-of-freedom adjustment mechanism enables the transfer bridge to adapt to freeboard changes under different tides and loading conditions, which is significantly better than the limitation of traditional fixed gangways that can only cope with limited height differences. 2. Dynamic stability guarantee: When the ship is berthing or berthing together, it may produce relative motion (such as roll and surge) due to factors such as wind, waves, and water currents, and the transfer bridge realizes dynamic compensation through a flexible structure. This design can still remain stable under 6-7 level crosswind conditions, avoiding operation interruption due to cable breakage or detachment of the gangway. 3. Optimized space utilization and operational efficiency: The transfer bridge adopts a foldable structure design. When not in use, the transfer bridge passage surface 2 can be folded back and stowed, reducing the deck area by approximately 30%-50%. The released space can be used to increase cargo loading or equipment layout.

[0032] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
