Description

TECHNICAL FIELD

[0001] The present application belongs to the field of boarding gangways, and particularly relates to a boarding gangway for a ro-ro passenger ship and a manufacturing method thereof. BACKGROUND

[0002] A ro-ro passenger ship is a special ship that combines passenger transport and cargo transport functions, and occupies an important position in the field of medium and short distance sea transport and inland ferry due to its convenience for vehicles to enter and exit the cargo hold with the help of its own power. Moreover, the unique roll-on / roll-off design greatly improves the loading and unloading efficiency, realizes water-land direct intermodal transport, and effectively promotes personnel exchanges and material circulation between regions. For a ro-ro passenger ship, a safe and efficient boarding method for personnel and vehicles is crucial, and the boarding gangway becomes a key equipment. However, the common boarding gangways on the market have many drawbacks. The existing gangways have a steep slope and a narrow width, and usually only one person can walk on them. Moreover, during walking, personnel are prone to face a high safety risk, i.e., prone to cause accidents such as slipping and colliding, especially for some passengers with inconvenient legs and feet, and passengers with large luggage.

[0003] At the same time, the problem of resource waste in the process of updating and iterating port equipment is increasingly prominent. For example, as the service life increases and technology updates, many portal cranes face scrapping due to equipment aging and performance degradation. If the scrapped portal cranes are directly discarded, not only a large amount of space is occupied, but also a serious waste of resources such as steel is caused. If they are disassembled and recycled, high labor and material costs are required, and the disassembly process may also cause environmental pollution. SUMMARY

[0004] The present application aims to develop a boarding gangway for a ro-ro passenger ship and a manufacturing method thereof that can improve boarding safety and convenience and effectively recycle waste resources, in order to solve the safety problems of existing boarding gangways and realize the resource utilization of scrapped equipment.

[0019] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0020] Example 1 like Figure 1 , Figure 2 As shown, this embodiment provides a boarding gangway for ro-ro passenger ships, comprising a cross gantry 18 directly removed from a scrapped gantry crane. The cross gantry 18 consists of a support platform 2, outriggers 1, a traveling mechanism 11, cables, and other components. Four outriggers 1 are evenly distributed on the outer side of the support platform 2, and each outrigger 1 has a traveling mechanism 11 at its lower end. This traveling mechanism 11 allows the gangway to travel on the gantry crane tracks installed in the port, moving it to a designated location. Therefore, this embodiment not only eliminates the need for additional dedicated tracks, reducing infrastructure costs, but also allows for rapid adjustment of the overall position according to the berthing location of the ro-ro passenger ship and the needs of terminal operations, significantly improving the equipment's versatility and the flexibility of port operations.

[0021] Moreover, as preferred, the cross portal 18 can also directly apply the wind-proof anchoring structure of the on-site portal crane, as the wind-proof anchoring device of the boarding gangway of the passenger-cargo ship, to firmly fix it to the wharf, so as to have higher wind resistance and overturning resistance, and effectively resist the impact of extreme environment such as strong wind and sea waves, to ensure the safety of equipment and personnel; at the same time, it can also reduce the design and maintenance cost of additional anchoring devices, further embodying the innovative concept of efficient reuse, cost reduction and efficiency increase of the embodiment. In this way, the embodiment can efficiently reuse the core components of the portal crane which would otherwise face abandonment or high disassembly cost by using the cross portal of the portal crane as the main structure; thereby greatly reducing the manufacturing cost of the new gangway, reducing the consumption of raw materials such as steel, and effectively alleviating the problem of port space occupation, which is in line with the concept of green environmental protection and circular economy.

[0022] In addition, the embodiment additionally adds a gangway structure on the basis of the existing cross portal 18. Specifically, as shown in Figure 2 Figure 3 The embodiment is installed on the top of the support platform 2 of the cross portal 18, and an operating room 13 is arranged on one side of the lap joint platform 4, which is used to install various controllers to facilitate the driver to operate it. A moving platform 14 is installed on the upper end surface of the lap joint platform 4, a walking trolley 15 is horizontally slidably installed on the upper end of the moving platform 14, the walking trolley 15 can adopt conventional linear driving mechanisms such as belt drive and chain drive, and a trolley turntable 16 is rotatably installed on the upper end of the walking trolley 15, and a floating ladder 17 is installed on the upper end of the trolley turntable 16; and the floating ladder 17 is moved horizontally by controlling the walking trolley 15 on the moving platform 14 to change the distance between the floating ladder 17 and the entrance and exit of the passenger ship; the angle of the floating ladder 17 is changed by controlling the rotation of the trolley turntable 16 to ensure that it can be smoothly connected at the entrance and exit of the passenger ship.

[0023] ​At least one first-stage gangway 5 is arranged on each side of the overlapping platform 4, and the lower ends of all first-stage gangways 5 on the same side are connected to a first-stage buffer platform 6, which is fixedly installed on the outer side of the corresponding support leg 1. Meanwhile, two first-stage buffer platforms 6 are each connected to a second-stage gangway 7, and the lower ends of the two second-stage gangways 7 are connected to a second-stage buffer platform 10, which is located inside the cross portal and is connected to a main passage gangway 9 and a secondary passage gangway 8. Moreover, in order to ensure that the passenger roll-on / roll-off ship boarding gangway is not bumped by ground obstacles when moving, there is a gap of about 10 cm between the lower end of the main passage gangway 9 and the ground, and there is also a gap of about 10 cm between the lower end of the secondary passage gangway 8 and the ground.

[0024] Based on this, the first embodiment can form a full-range safety guarantee system through the multi-stage buffer platform and the stepped gangway design, while meeting the rapid passage demand of multi-directional human flow, effectively improving the boarding efficiency, and avoiding the occurrence of accidental incidents such as slipping and collision. Moreover, as an optimization, in order to further improve the safety factor of the entire passenger roll-on / roll-off ship boarding gangway, the first embodiment can be provided with a falling prevention net 12 on the end of the overlapping platform 4 closest to the passenger ship, and guardrails 3 are arranged on the edges of the overlapping platform 4, the edges of the first-stage gangway 5, the edges of the first-stage buffer platform 6, the edges of the second-stage gangway 7, the edges of the main passage gangway 9, and the edges of the secondary passage gangway 8, and the falling prevention net 12 and the guardrails 3 are used to avoid accidental falling events. Meanwhile, the first embodiment can be provided with lighting lamps at the overlapping platform 4, and the lighting lamps can provide sufficient and uniform lighting in the night or in an environment with insufficient light, effectively avoiding accidents such as stepping in the air and collision due to blocked vision, and significantly improving the safety of night boarding operations.
