Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine gangway technology, and in particular to a marine gangway device and a ship. Background Technology
[0002] Marine gangways are primarily movable ladders used by ship's crew to board and disembark. They mainly consist of access platforms, ladder bodies, handrails, folding ladders, lifting devices, and securing mechanisms. Due to variations in ship size and usage requirements, typically one gangway is installed on each side. However, for large passenger ships and specialized vessels with frequent boarding and disembarking, such as hospital ships, two gangways may be required on each side. Currently, gangways are generally located at the edge of the lowest deck passageway on both sides of the ship, not enclosed by the hull plating. This allows them to be lifted, folded, and stored on the deck side during ship operation, and then flipped and lowered to the side when the ship is docked for crew access. Specifically, for vessels such as passenger ships and car carriers, typically only the highest one or two decks are designated as open decks, while other decks are enclosed by the hull plating. This means that a portion of the sheltered deck must be partitioned off and placed close to the sides for the gangways. Furthermore, to facilitate the deployment and retraction of the gangways, openings in the hull plating are required in these areas. This not only results in the gangways being low above the waterline and exposed, making them highly susceptible to damage from strong winds and waves during navigation, but also, since gangways are typically over ten meters long, the excessive space required for such vessels negatively impacts the number and functionality of passenger cabins, functional compartments, and vehicles, significantly reducing the overall usability of the vessel. Therefore, ensuring the stable placement of the gangways, preventing erosion from wind and waves, and minimizing their impact on the occupancy of the ship's interior compartments, while effectively improving the overall performance of the vessel, is a problem that those in the field need to solve. Utility Model Content
[0003] The purpose of this utility model is to provide a ship gangway device and a ship, so as to ensure the stable placement of the gangway, prevent it from being eroded by wind and waves, and not affect the space occupied by the ship's internal cabins, thereby effectively improving the overall performance of the ship.
[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] Marine gangway system, comprising:
[0006] The gangway includes a detachably connected ladder body and an upper platform, the upper platform being rotatably mounted in a closed deck area, the ladder body being placed on an open deck, and the ladder body also being equipped with detachably connected movable handrails;
[0007] A flip-up ladder lifting device is provided, which can flip the ladder body and lower it to the target position. At least two sets of the flip-up ladder lifting device are provided.
[0008] Alternatively, the upper platform can extend out of the enclosed deck area and connect to the ladder body.
[0009] Optionally, the ladder body is provided with a first eye plate, the upper platform is provided with a second eye plate, and the ladder lifting device can lower the ladder body to the corresponding connection of the first eye plate and the second eye plate.
[0010] Optionally, it also includes a winch that works in conjunction with the ladder lifting device and is capable of rotating the ladder body 90° and lowering it to the target position.
[0011] Alternatively, the winch and the ladder lifting device are configured in a one-to-one correspondence.
[0012] Optionally, it also includes a steel cable, which forms an inclined ladder after the ladder body is lowered to the target position, and the inclined ladder body is connected to the tilting ladder lifting device via the steel cable.
[0013] Alternatively, the steel cable is provided in a one-to-one correspondence with the lifting device of the escalator.
[0014] Optionally, a door is provided on the side of the enclosed deck area near the hull side, and the upper platform can be flipped out of the hull side through the opening of the door.
[0015] Optionally, the gangway may also include a lower platform, which is placed together with the gangway on the open deck.
[0016] On the other hand, a ship, including the ship gangway system, the ship having an open deck and a closed deck area, the upper platform of the gangway in the ship gangway system being placed in the closed deck area, and the remaining structure of the gangway being placed on the open deck.
[0017] The beneficial effects of this utility model are:
[0018] This invention separates the upper platform and the ladder body, with the upper platform placed in a sealed deck area and the ladder body placed in an open deck area. This minimizes the space occupied in the sealed deck area, effectively improving the overall performance of the ship and ensuring the ladder body is stably placed on the ship. Both placement methods also prevent erosion from sea waves, extending the service life of the gangway. Furthermore, the movable handrail is detachably connected to the ladder body, allowing for installation after the ladder body is placed in the target position, improving the overall storage efficiency of the gangway. Additionally, the ladder tilting and lifting device can tilt the ladder body and lower it to the target position, while the upper platform is also rotated and placed in the sealed deck area. This allows for segmented installation of the gangway, with the assembly of the upper platform and ladder body achieved through the lowering action of the tilting and lifting device. For example, this invention includes at least two sets of tilting and lifting devices, ensuring not only the stability of the ladder body tilting but also improving the stability of its lowering and lifting, and guaranteeing stable placement of the ladder body after it reaches the target position. Correspondingly, ships equipped with ship gangways can also achieve the above effects. Attached Figure Description

[0029] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.
[0030] like Figures 1-5 As shown, this embodiment provides a ship gangway device and a ship. The ship gangway device includes a gangway and a flip-up ladder lifting device 20. The gangway includes a detachably connected ladder body 11 and an upper platform 12. The upper platform 12 is rotatably disposed in the enclosed deck area 200. The ladder body 11 is placed on the open deck 100. The ladder body 11 is also provided with a detachably connected movable handrail 14. The flip-up ladder lifting device 20 can flip the ladder body 11 and lower it to the target position. At least two sets of flip-up ladder lifting devices 20 are provided.
[0031] Specifically, in this embodiment, the upper platform 12 and the ladder 11 are set up separately, with the upper platform 12 placed in the enclosed deck area 200 and the ladder 11 placed in the open deck 100. This ensures that the space occupied in the enclosed deck area 200 is reduced, effectively improving the overall performance of the ship, and ensuring that the ladder 11 is stably placed on the ship. Both placement methods can avoid erosion from sea waves, extending the service life of the gangway. Furthermore, the movable handrail 14 is detachably connected to the ladder 11, so that the movable handrail 14 can be installed after the ladder 11 is placed in the target position, improving the overall storage efficiency of the gangway. Furthermore, the flip-up ladder lifting device 20 can flip the ladder 11 and lower it to the target position, and the upper platform 12 is also rotated and set in the enclosed deck area 200. This allows for the installation of the gangway in sections, and the assembly between the upper platform 12 and the ladder 11 is achieved through the lowering action of the flip-up ladder lifting device 20. For example, in this embodiment, at least two sets of the ladder lifting device 20 are provided, which not only ensures the stability of the ladder body 11 during tilting, but also improves its stability during lowering and lifting, and ensures its stable placement after the ladder body 11 reaches the target position. Correspondingly, ships equipped with marine gangway devices can also achieve the above effects.
[0032] The specific structure of the ship gangway device in this embodiment is described below.
[0033] Combination Figures 1-4As shown, the ship's gangway device in this embodiment includes a gangway, a tilting and lifting device 20, a winch 30, and a steel cable 40. The gangway in this embodiment also includes a ladder body 11, an upper platform 12, a lower platform 13, and a movable handrail 14. Optionally, in this embodiment, the upper platform 12 and the movable handrail 14 are separately arranged from the ladder body 11, while the lower platform 13 is integrated with the ladder body 11. Specifically, the upper platform 12 is rotatably mounted in the enclosed deck area 200, while the ladder 11 and lower platform 13 are placed on the open deck 100 at the top. The movable handrail 14 can be stored as needed. This allows the gangway to be stored on the ship when not in use, avoiding damage from being too close to the water surface in the event of strong winds and waves. Placing a small portion of the gangway in the enclosed deck area 200 and the majority on the open deck 100 improves the overall space utilization of the ship. With the gangway effectively stored, ample usable space in the enclosed deck area 200 is maintained, significantly increasing the number of passenger cabins, multi-functional cabins, or vehicles, thus improving the overall performance of the ship. Furthermore, in this embodiment, the ladder 11 can be flipped using the ladder lifting device 20, allowing it to be stored on the open deck 100 with a smaller footprint. Meanwhile, the ladder lifting device 20 can also lower the ladder body 11 to the target position, thereby ensuring a stable connection between the ladder body 11 and the upper platform 12, and allowing for precise placement on the ground to ensure crew passage. For example, in this embodiment, a winch 30 and a steel cable 40 are provided in a one-to-one correspondence with the ladder lifting device 20, thereby enabling the gangway to be quickly disassembled, stored, and used stably through the coordinated action of the three.
[0034] Combination Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the ladder body 11 of the gangway is provided with a first eye plate 111, and correspondingly, the upper platform 12 is provided with a second eye plate. The ladder body 11 can be lowered to the upper platform 12 by the ladder lifting device 20 until the first eye plate 111 and the second eye plate are connected, thereby completing the stable connection between the ladder body 11 and the upper platform 12. Specifically, in this embodiment, at least two sets of ladder lifting devices 20 are provided, and they are spaced apart on the open deck 100. Parallel to the ladder lifting devices 20 and perpendicular to the open deck 100, several fixing columns are also provided. The ladder body 11 can be fixed to the open deck 100 by the ladder lifting devices 20 and the fixing columns. Specifically, in the initial state of the ladder 11, the length direction of the ladder 11 is the same as the length direction of the open deck 100, and the ladder 11 is set perpendicular to the open deck 100. This avoids occupying too much space on the open deck 100, ensuring the functionality of the open deck 100, and preventing the ladder 11 from being too close to the sea level during subsequent ship operation, thus avoiding erosion by seawater and the influence of sea wind.
[0035] Optionally, when using the ladder 11, it is necessary to first rotate the ladder 11 90° from its perpendicular position to the open deck 100 using the ladder tilting and lifting device 20 to achieve a parallel position with the open deck 100. Furthermore, the ladder 11 can be positioned at the edge of the open deck 100, so that after the ladder 11 is rotated, it can extend out of the ship under the action of the ladder tilting and lifting device 20, allowing for direct lowering and facilitating subsequent use of the gangway. Figure 2 and Figure 4 As shown, exemplarily, after the flip-up ladder lifting device 20 flips the ladder body 11, the flipped-up ladder lifting device 20' will lower the ladder body 11. Figure 5 As shown, the gangway is lowered until the flipped ladder lifting device 20' lowers the ladder body 11 to the horizontal upper platform 12' formed by the rotation of the upper platform 12. Different lowering distances are achieved using steel cables 40 and winches 30 to ensure the ladder body 11 is tilted. Finally, the ladder body 11 is lowered to the target position, forming an inclined ladder body 11'. The movable handrail 14 is then installed to complete the installation of the gangway, allowing crew members to use it. At this point, the inclined ladder body 11' is tightly connected to the flipping ladder lifting device 20 via steel cables 40 to ensure the stability of the gangway. Correspondingly, the reverse operation allows for the retrieval of the ladder body 11.
[0036] Combination Figure 1 and Figure 4 As shown, in this embodiment, the lower platform 13 is connected to the ladder body 11, and both are placed on the open deck 100. This ensures the stability of the bottom of the gangway by allowing it to contact the ground when the ladder body 11' is tilted. Optionally, in this embodiment, the movable handrail 14 includes a handrail and a railing. The railing can be inserted into the ladder body 11, thereby achieving a detachable connection between the movable handrail 14 and the ladder body 11. Figure 2 and 5 As shown, in this embodiment, the enclosed deck area 200 has an upper deck 201 at the top and a lower deck 202 at the bottom, and a port door 301 is provided on the side of the enclosed deck area 200 near the side 300. Optionally, the upper platform 12 is rotatably disposed in the enclosed deck area 200 and can extend out of the enclosed deck area 200 after rotation and connect with the ladder 11. Specifically, in this embodiment, the upper platform 12 can be flipped out of the side 300 through the opening of the port door 301, thereby connecting with the first eye plate 111 through the second eye plate, realizing the assembly and disassembly of the upper platform 12 and the ladder 11. This ensures the stable housing of the upper platform 12, avoiding the impact of sea waves, while also occupying less space in the enclosed deck area 200, thereby expanding the space of other cabins of the ship and improving the functionality of the ship. Figure 4As shown, exemplarily, the upper platform 12 is rotated 90° and positioned parallel to the lower deck 202. Then, the ladder body 11 is lowered to the lower deck 202 via the ladder lifting device 20 and connected to the upper platform 12. After connection, the ladder body 11 is further tilted and lowered to form an inclined ladder body 11'. Exemplarily, in this embodiment, the rotation of the upper platform 12 is achieved manually, facilitating crew operation. In other embodiments, manual operation can be replaced with automated mechanical operation; this is not a limitation. Furthermore, gangway doors 301 can be provided on both sides 300 to allow for the use of multiple gangways.
[0037] Optionally, in this embodiment, at least two sets of the ladder tilting and lifting device 20 are provided, and the specific number can be set as needed to ensure the stable storage of the ladder body 11 and the stability of the ladder body 11 after reaching the target position. Optionally, in this embodiment, the ladder tilting and lifting device 20 includes a ladder tilting structure and a lifting structure. The ladder tilting structure can rotate the ladder body 11 from a vertical state by 90° and extend it out of the open deck 100 to a horizontal state. Then, under the action of the lifting structure, the horizontal ladder body 11 is lowered to the lower deck 202 and connected to the tilted upper platform 12. Then, by adjusting the different lowering distances of the two lifting structures, the ladder body 11 reaches the target position, forming an inclined ladder body 11'. Further, in this embodiment, the winch 30 is used in conjunction with the ladder tilting and lifting device 20, and the two can rotate the ladder body 11 by 90° and lower the ladder body 11 to the target position. That is to say, the winch 30 and the ladder tilting and lifting device 20 are set one-to-one to ensure the stability of the operation and the power source. Furthermore, the steel cable 40 is also set one-to-one with the flip-up ladder lifting device 20, so that the steel cable 40 can ensure the stable flipping and lowering of the ladder body 11, and make the connection between the tilted ladder body 11' and the flip-up ladder lifting device 20 stable, which facilitates subsequent storage operations.
[0038] On the other hand, the specific structure of the ship in this embodiment will be described.
[0039] Specifically, the ship includes the aforementioned ship gangway device, and the ship is equipped with an open deck 100 and a closed deck area 200. By separating the upper platform 12 of the gangway and the other structures in the ship gangway device, and placing the upper platform 12 in the closed deck area 200 and the other structures on the open deck 100, the utilization rate of ship space can be effectively improved. While avoiding the gangway from being damaged by wind and waves, the usable area of the closed deck area 200 is reduced, thereby improving the functionality of the ship.
[0040] Workflow: First, open the gangway door 301 and manually flip the upper platform 12 to form a horizontal upper platform 12'. Then, operate the two winches 30 simultaneously to flip the gangway ladder 11 to a horizontal position and lower the ladder 11 horizontally until the first eye plate 111 is flush with the second eye plate of the horizontal upper platform 12'. Connect the two. Finally, operate the winch 30 closer to the horizontal upper platform 12' to release a section of steel cable 40. Then, operate the winch 30 further away to lower the bottom of the gangway to the dock and install the movable handrail 14. After that, personnel can board the gangway.
