Description

Technical Field

[0001] The utility model relates to the technical field of gangway devices, in particular to an anti-deviation type gangway device for a ro-ro passenger ship. Background Art

[0002] Ro-Ro Passenger (RoPax) vessels are specialized vessels that allow vehicles and other wheeled cargo to enter and exit the vessel's hold under their own power, while also carrying passengers. A RoPax ferry's ramp is a critical vessel auxiliary device, allowing vehicles and pedestrians to enter and exit the vessel directly from the shore or dock. The design of the ramp must ensure safety, reliability, and adaptability to varying dock conditions and weather conditions.

[0003] When the gangway device is in use, when vehicles and passengers get on and off the ship, uneven load distribution will cause the gangway to be unevenly stressed, resulting in deviation. At the same time, the gangway will also be affected by wind and waves, which will cause it to deviate. Therefore, an anti-deflection gangway device for passenger and vehicle ferries is proposed.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The utility model provides a technical solution, an anti-deflection type gangway device for passenger ro-ro ship, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 ,include:

[0030] The gangway 1, the hull 3 and the hydraulic telescopic rod 4, the hydraulic telescopic rod 4 is rotatably mounted on the front and rear sides of the hull 3, and the hydraulic telescopic rod 4 is rotatably connected to the gangway 1;

[0031] Side frames 8 are provided at the left and right ends of the front and rear sides of the exterior of the springboard 1, and the side frames 8 are connected to the springboard 1. A water storage pipe 9 is provided inside the side frames 8.

[0032] The water inlet pipe 13 is provided at the left end of the water storage pipe 9;

[0033] The winch 5 is provided on the front and rear sides of the hull 3 and is connected to the hull 3;

[0034] The steel cable 6 is arranged on the outside of the winch 5. A seawater submersible pump 7 is provided at the lower end of the steel cable 6, and the seawater submersible pump 7 is connected to the steel cable 6. The output end of the seawater submersible pump 7 is connected to the water inlet pipe 13 through a pipeline. The winch 5 is used to control the lifting and lowering of the seawater submersible pump 7, so as to facilitate sinking into the water and rising out of the water, so that the seawater submersible pump 7 can pump water into the water storage pipe 9.

[0035] When in use, the hydraulic telescopic rod 4 is activated to control the springboard 1 to flip toward the land until one end of the springboard 1 contacts the land. At this time, the extension board 2 contacts the land and is supported by the anti-slip strip 14. The winch 5 is activated to release the steel cable 6, thereby immersing the seawater submersible pump 7 in the water. The seawater submersible pump 7 is activated to pump water into the water inlet pipe 13 through the pipeline. Then, the water passes through the water inlet pipe 13 into the water storage pipe 9 and fills the water storage pipe 9. This increases the weight of the water storage pipe 9. The water is pumped into the water storage pipe 9 by the seawater submersible pump 7, thereby improving the temporary quality of the springboard 1, improving the stability of the overall structure, and reducing the displacement caused by external forces. This utilizes the basic principle of physical mechanics that the lower the center of gravity, the better the stability of an object or system. It should be noted that in order to save space and highlight the innovative elements of this patent, this solution is based on the existing springboard and improves its related structures. Some conventional equipment, such as the hydraulic telescopic rod 4, winch 5, steel cable 6, seawater submersible pump 7, servo motor 12, etc., are not described in detail in this patent.

[0036] See also Figure 1 、 Figure 2 and Figure 3 Five equally spaced bends 10 are provided at the upper end of the water storage pipe 9, and the bends 10 are sealed and fixed to the water storage pipe 9. The bends 10 are connected to the water storage pipe 9. The bends 10 are used to discharge the air inside the water storage pipe 9 when filling water, and to discharge water when draining.

[0037] See also Figure 1 and Figure 2 Side frames 11 are provided on both the front and rear sides of the right end of the outside of the springboard 1 , and the side frames 11 are connected to the springboard 1 , and the side frames 11 are used to install the servo motor 12 .

[0038] See also Figure 1 and Figure 2 A servo motor 12 is installed inside the side frame 11 and is connected to the side frame 11 .

[0039] See also Figure 1 、 Figure 2 and Figure 3 The end of the water storage pipe 9 facing away from the water inlet pipe 13 is connected to the output end of the servo motor 12, and the servo motor 12 is used to control the rotation of the water storage pipe 9.

[0040] See also Figure 1 and Figure 4 An extension plate 2 is provided at the end of the gangway 1 facing away from the hull 3, and the extension plate 2 is rotatably connected to the gangway 1 by a hinge. The gangway 1 is rotatably connected to the hull 3 by a hinge. The extension plate 2 is used to extend the length of the gangway 1 and change the bending angle of the gangway 1 to facilitate the passage of vehicles and pedestrians.

[0041] See also Figure 1 and Figure 4 The lower end of the extension plate 2 is provided with equidistantly distributed anti-slip strips 14, and the anti-slip strips 14 are connected to the extension plate 2. The anti-slip strips 14 improve the anti-slip performance of the bottom of the extension plate 2.

[0042] In this solution, after the hull 3 approaches the shore, the hydraulic telescopic rod 4 is activated to control the gangway 1 to flip toward the land until one end of the gangway 1 contacts the land. At this time, the extension board 2 contacts the land and is supported by the anti-slip strip 14. The winch 5 is activated to release the steel cable 6, thereby immersing the seawater submersible pump 7 in the water. The seawater submersible pump 7 is activated to pump water into the water inlet pipe 13 through the pipeline. The water then passes through the water inlet pipe 13 into the water storage pipe 9 and fills the water storage pipe 9. This increases the weight of the water storage pipe 9. The water pumped into the water storage pipe 9 by the seawater submersible pump 7 improves the temporary quality of the gangway 1, improves the stability of the overall structure, and reduces displacement caused by external forces. This utilizes the basic principle of physical mechanics that the lower the center of gravity, the better the stability of an object or system. When the gangway 1 needs to be reset, the servo motor 12 is activated to cause the water storage pipe 9 to flip outward. The water storage pipe 9 flips to the end outside the curved pipe 10 and tilts downward. At this time, the water inside the water storage pipe 9 is quickly discharged through the curved pipe 10. After the water is discharged, the hydraulic telescopic rod 4 is controlled to erect the gangway 1.
