Description

Technical Field

[0001] This utility model relates to the field of ship boarding equipment technology, specifically to a multifunctional gangway structure. Background Technology

[0002] In recent years, an increasing number of ultra-large container ships have been delivered and put into use. To avoid excessively long gangways that would occupy upper deck space, it is generally considered to carve out a space in the outer plating for the gangway. However, the following problems are often found in operation: 1) When the height of the dock is lower than the height of the gangway boarding deck but the difference is not significant, ships using this type of gangway design are prone to the problem of the gangway boom obstructing personnel passage; 2) When the height of the dock is slightly higher than the height of the boarding deck, the platform under the gangway cannot even be connected to the dock.

[0003] To address the aforementioned issues and avoid using excessively long single gangways on the upper deck, some ships employ a double gangway design, both for the upper and lower decks. However, this undoubtedly increases costs significantly. Therefore, developing a low-cost and highly adaptable multi-functional gangway has become a pressing problem that needs to be solved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a multifunctional gangway structure that is simple in structure and easy to operate. It can achieve passage through the cooperation of the lower platform and the dock ladder II, and can also achieve rapid passage between the boarding deck and the dock through the cooperation of the upper platform and the dock ladder I. This solves the problem of insufficient passage height under the gangway boom, and has low cost and strong adaptability.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The innovative feature of this multifunctional gangway structure is that it includes a gangway support, an upper platform, a turntable, support frames, a transition platform, and a dock ladder I. A gangway support is welded to the boarding deck near the hull side, and the upper platform is horizontally spaced on the boarding deck relative to the gangway support on the outward side. One end of the upper platform is vertically hinged to the gangway support, and a turntable is horizontally rotatable on its upper surface near the outward side. Support frames are spaced along the bow and stern direction on the outer circumference of the turntable near the outward side. One end of the horizontally positioned transition platform is vertically hinged to the ends of the two support frames away from the turntable along the radial direction of the turntable. The other end of the transition platform extends horizontally outward and is vertically hinged to one end of the dock ladder I, allowing the other end of the dock ladder I to be supported on the dock, thereby enabling personnel passage between the boarding deck and the dock.

[0006] Preferably, it also includes support seats; on the boarding deck, support seats are vertically spaced symmetrically at intervals along the bow and stern directions, directly below the upper platform and on the outer side of the gangway support, with each support seat spaced apart from the gangway support, and the upper platform in a horizontal state is supported and fixed by the support seats.

[0007] Preferably, the rotation direction of the upper platform around the gangway support, the rotation direction of the dock ladder I around the transition platform, and the rotation direction of the transition platform around the support frame are all consistent.

[0008] Preferably, both support frames are vertically welded and fixed to the outer circumference of the turntable, and the end of each support frame away from the turntable is a fan-shaped structure vertically arranged along the radial direction of the turntable. A first rotating shaft is also horizontally and vertically provided on the front and rear end faces of the transition platform near the support frame, and one end of the transition platform is spaced between the two support frames and vertically rotatably connected to the two support frames through the first rotating shaft. In the fan-shaped portion of each support frame, through holes matching the pins are vertically embedded and opened at intervals along its circumference. Locking holes matching the pins are also vertically embedded and opened on the front and rear end faces of the transition platform relative to the opening trajectory of the through holes. Thus, after the transition platform is vertically rotated around the support frame for angle adjustment, the transition platform and the support frame are locked and fixed by the cooperation of the pins, locking holes and corresponding through holes.

[0009] Preferably, the included angle between each adjacent through hole is 45°, thereby allowing the transition platform to be adjusted in 45° increments within the range of -45° to 90°.

[0010] Preferably, square steel steps are arranged horizontally along the width of the transition platform at intervals along its length in the middle position of the transition platform, and adjacent square steel steps are set at an arc angle of 20° to 35°, so as to ensure that personnel can pass smoothly through the transition platform at different angles.

[0011] Preferably, on the end face of the transition platform away from the support frame, there are symmetrically spaced vertical hanging brackets I, and on one end face of the dock ladder I, there are also vertically spaced hooks I that match each hanging bracket I. Thus, through the cooperation of the hooks I and the corresponding hanging brackets I, one end of the dock ladder I is vertically hinged to the transition platform. At the connection between each hook I and the corresponding hanging bracket I, there is also an anti-detachment ring I, which prevents the dock ladder I from detaching. On the lower surface of the dock ladder I, near its other end, there are also symmetrically spaced roller assemblies I, and the dock ladder I is supported on the dock by the roller assemblies I.

[0012] Preferably, it also includes a ladder frame, a lower platform, a hanging frame II, a dock ladder II, a hook II, an anti-detachment ring II, and a roller assembly II; a ladder frame is also vertically hinged to the outer circumference of the turntable along its radial direction, the ladder frame is located on the counterclockwise side of the support frame, and the included angle between the ladder frame and the support frame is 90°, ensuring that the vertical rotation of the ladder frame and the vertical rotation of the transition platform do not interfere with each other; a lower platform is also hinged to the end of the ladder frame away from the turntable, and the end face of the lower platform on the same side as the transition platform is symmetrically and vertically arranged at intervals. There is a bracket II, and at one end face of the dock ladder II, a hook II that matches the bracket II is also vertically provided relative to each bracket II position. Thus, through the cooperation of the hook II and the corresponding bracket II, one end of the dock ladder II is vertically hinged to the lower platform. At the connection between each hook II and the corresponding bracket II, an anti-detachment ring II is also provided to prevent the dock ladder II from detaching. On the lower surface of the dock ladder II, near its other end, roller assemblies II are symmetrically arranged at intervals, and the dock ladder II is supported on the dock by the roller assemblies II.

[0013] The beneficial effects of this utility model are: (1) This utility model has a simple structure and is easy to operate. It can achieve the purpose of passage through the cooperation of the lower platform and the dock ladder II, and can also achieve the rapid passage of personnel between the boarding deck and the dock through the cooperation of the upper platform and the dock ladder I. This solves the problem of insufficient passage height under the gangway boom, and has low cost and strong adaptability. (2) This utility model can be matched with dock ladder I and dock ladder II of different lengths and different step forms, and has a wide range of applications; (3) The angle of the dock ladder I can be adjusted by flipping the transition platform, so that passage can be guaranteed even when the dock height is slightly higher than the boarding deck height, which is highly adaptable.

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below through specific embodiments.

[0023] This utility model discloses a multifunctional gangway structure, including a gangway support 2, an upper platform 3, a turntable 4, a support frame 5, a transition platform 7, and a dock ladder I 10; the specific structure is as follows. Figures 1-6 As shown, a gangway support 2 is welded to the boarding deck 1 near the hull side, and an upper platform 3 is horizontally spaced on the boarding deck 1 on the side of the gangway support 2 that is closer to the hull side. One end of the upper platform 3 is vertically hinged to the gangway support 2, and a turntable 4 is horizontally rotatable on its upper surface near the hull side. Support frames 5 are spaced along the bow and stern direction on the outer circumference of the turntable 4 near the hull side. One end of the horizontally arranged transition platform 7 is vertically hinged to the two support frames 5 away from the turntable 4 in the radial direction. The other end of the transition platform 7 extends horizontally towards the hull side and is vertically hinged to one end of the dock ladder I 10, so that the other end of the dock ladder I 10 is supported on the dock 20, thereby enabling personnel passage between the boarding deck 1 and the dock 20. The rotation direction of the upper platform 3 around the gangway support 2, the rotation direction of the dock ladder I 10 around the transition platform 7, and the rotation direction of the transition platform 7 around the support frame 5 are all the same.

[0024] like Figure 1 , Figure 2 As shown, on the boarding deck 1, there are vertically spaced and symmetrically arranged support seats on the outer side of the boarding deck 3 and the gangway support 2, directly below the boarding deck 3 and along the bow and stern. Each support seat is spaced apart from the gangway support 2 and supports and fixes the boarding deck 3, which is in a horizontal state.

[0025] In this utility model, both support frames 5 are vertically welded and fixed to the corresponding positions on the outer circumference of the turntable 4, and the end of each support frame 5 away from the turntable 4 is a fan-shaped structure vertically arranged along the radial direction of the turntable 4; for example Figures 1-6 As shown, a first rotating shaft is horizontally and vertically provided on the front and rear ends of the transition platform 7 near the support frame 5, and one end of the transition platform 7 is spaced between two support frames 5, and is vertically rotatably connected to the two support frames 5 through the first rotating shaft; each support frame 5 has a through hole 21 that matches the pin, which is vertically embedded in the fan-shaped part along its circumference; and a locking hole that matches the pin is vertically embedded on the front and rear ends of the transition platform 7 relative to the trajectory of the through hole 21. After the transition platform 7 is vertically rotated around the support frame 5 to adjust the angle, the transition platform 7 and the support frame 5 are locked and fixed by the cooperation of the pin, the locking hole and the corresponding through hole 21; wherein, the included angle between each adjacent through hole 21 is 45°, so that the transition platform 7 can be adjusted in 45° increments within the range of -45° to 90°.

[0026] like Figure 2 , Figure 4 , Figure 5 As shown, square steel steps 9 are also arranged horizontally along the width direction of the transition platform 7 at intervals along its length in the middle position of the transition platform 7, and adjacent square steel steps 9 are set with an arc angle of 20°~35°, so as to ensure that personnel can pass smoothly through the transition platform 7 at different angles.

[0027] like Figures 1-6 As shown, on the end face of the transition platform 7 away from the support frame 5, there are also symmetrically spaced vertical hanging brackets I8. On one end face of the dock ladder I10, there are also vertically spaced hooks I11 that match each hanging bracket I8. Thus, through the cooperation of the hooks I11 and the corresponding hanging brackets I8, one end of the dock ladder I10 is vertically hinged to the transition platform 7. At the connection between each hook I11 and the corresponding hanging bracket I8, there is also an anti-detachment ring I12, which prevents the dock ladder I10 from detaching. On the lower surface of the dock ladder I10, near its other end, there are also symmetrically spaced roller assemblies I13, and the dock ladder I10 is supported on the dock 20 by the roller assemblies I13.

[0028] This utility model also provides a ladder frame 6 vertically hinged along the radial direction on the outer circumference of the turntable 4, such as... Figures 1-6As shown, the ladder frame 6 is located on the counterclockwise side of the support frame 5, and the angle between the ladder frame 6 and the support frame 5 is 90°, ensuring that the vertical rotation of the ladder frame 6 and the vertical rotation of the transition platform 7 do not interfere with each other; a lower platform 14 is also hinged to the end of the ladder frame 6 away from the turntable 4, and a hanging bracket II 15 is symmetrically and vertically arranged at intervals on the end face of the lower platform 14 on the same side as the transition platform 7, and a hanging bracket II 15 is also vertically arranged on one end face of the dock ladder II 16 relative to each hanging bracket II 15 position. 5. Matching hooks II17 are provided, and through the cooperation of hooks II17 and corresponding hangers II15, one end of the dock ladder II16 is vertically hinged to the lower platform 14; at the connection between each hook II17 and the corresponding hanger II15, an anti-detachment ring II18 is also provided, and the anti-detachment ring II18 is used to prevent the dock ladder II16 from detaching; on the lower surface of the dock ladder II16, near its other end, roller assemblies II19 are symmetrically arranged at intervals, and the dock ladder II16 is supported on the dock 20 by the roller assemblies II19.

[0029] The working principle of this utility model: When the ship docks, and the pier 20 is below the boarding deck 1 and far away, first rotate the turntable 4 horizontally to make the ladder 6 extend out of the boarding deck 1, then lower the ladder 6 to a suitable height, and then install the appropriate pier ladder II 16 on the bracket II 15 on one side of the lower platform 14 through the hook II 17, and let one end of the pier ladder II 16 be supported on the pier 20 through the roller assembly II 19, so that personnel can pass through. When the ship docks and the pier 20 is close to or even slightly higher than the boarding deck 1, the turntable 4 is first rotated horizontally to extend the transition platform 7 out of the boarding deck 1. Then, the angle of the pier ladder I10 is adjusted by flipping the transition platform 7. The transition platform 7 is then locked to the support frame 5 through the cooperation of the through hole 21, the lock hole and the pin. Then, the appropriate pier ladder I10 is installed on the bracket I8 of the transition platform 7 through the hook I11, and one end of the pier ladder I10 is supported on the pier 20 by the roller assembly I13. At this time, personnel can pass through quickly, and this process does not require the addition of an extra gangway.

[0030] The beneficial effects of this utility model are: (1) This utility model has a simple structure and is easy to operate. It can achieve passage through the cooperation of the lower platform 14 and the dock ladder II 16, and can also achieve rapid passage between the boarding deck 1 and the dock 20 through the cooperation of the upper platform 3 and the dock ladder I 10, thus solving the problem of insufficient passage height under the gangway boom. It has low cost and strong adaptability. (2) This utility model can be matched with dock ladder I10 and dock ladder II16 of different lengths and different step forms, and has a wide range of applications; (3) The angle of the dock ladder I10 can be adjusted by flipping the transition platform 7, so that passage can be guaranteed even when the height of the dock 20 is slightly higher than the height of the boarding deck 1, which is highly adaptable.
