Description

Passenger roller boat

Technical Field

The invention relates to the technical field of ships, in particular to a ro-ro passenger ship.

Background

A passenger rolling ship, also called as a transport ship for opening and closing, is a transport ship for loading and unloading goods by directly entering and exiting a cargo hold through a semitrailer or a wheeled tray loaded with box goods or other goods pulled by a tractor. Cargo carried by the ro-ro passenger ship enters and exits the cargo compartment through the power of the ro-passenger ship and can carry passengers at the same time. It is used for river ferry and medium and short sea transportation. At present, the first, third and fifth decks of the MSC ro-ro passenger ship are decks for loading vehicles, and since the middle part of the third deck has no trunk or room similar to other ro-passenger ships at the midship line as a support for the fifth deck, the fifth deck is deformed after loading vehicles through the calculation of the structure.

In the prior art, in order to improve the strength of the fifth deck, the strength can be improved by adding the encryption beam, and accordingly, about 30 beams can be added by adding the encryption beam, the structural weight of 157 tons can be increased, about 2 tons of joints can be added on the beams, and the number of about 100 electric lamps can be increased, so that the cost can be increased, the weight of the ship can be increased, the center of gravity of the ship can be increased, and the ship is not favorable for sailing. In addition, the transverse T-shaped beam can be subjected to encryption treatment, and the fifth deck is supported in a mode of adding pillars at several places, so that although the use of the encryption beams can be reduced, the pillars can obstruct the passing of third deck vehicles and influence the cargo carrying capacity of the passenger-rolling ships.

Therefore, a roll-in ship is needed to solve the above problems.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 4, the present embodiment provides a ro-ro passenger ship, which comprises a port side 11, a starboard side 12, a first deck 21, a third deck 22, a fifth deck 23 and a support assembly 3 capable of being selectively supported between the third deck 22 and the fifth deck 23, wherein the port side 11 and the starboard side 12 are arranged in parallel, the first deck 21, the third deck 22 and the fifth deck 23 are arranged in parallel between the port side 11 and the starboard side 12 from bottom to top in the vertical direction, and the first deck 21, the third deck 22 and the fifth deck 23 are all used for carrying cargo.

The supporting component 3 supported between the third deck 22 and the fifth deck 23 is arranged and used for supporting the fifth deck 23 when the fifth deck 23 is used for loading cargoes, so that the fifth deck 23 is prevented from deforming, and the reliability and the safety of the fifth deck 23 for loading cargoes are ensured; meanwhile, other structures are not added on the basis of the structures of the third deck 22 and the fifth deck 23, the weight of the ro-ro passenger ship is not increased too much, and meanwhile, the cost is lower and the economic benefit is better; in addition, by selectively supporting the supporting member 3 between the third deck 22 and the fifth deck 23, the loading of the cargo on the third deck 22 is not affected, and the loading efficiency and the loading capacity of the ro-ro passenger ship are ensured.

In particular, the support assembly 3 is provided with a support position and a storage position, the support assembly 3 in the support position is supported between the third deck 22 and the fifth deck 23 for supporting the fifth deck 23; the supporting component 3 at the storage position is arranged below the fifth deck 23, so that the influence of the supporting component 3 on the third deck 22 when supporting the goods can be effectively avoided, and the loading efficiency of the ro-ro passenger ship can be ensured.

Further, the supporting assembly 3 comprises a first supporting column 31, a second supporting column 32 and a supporting driving member 33, wherein one end of the first supporting column 31 is rotatably arranged below the fifth deck 23; one end of the second support column 32 is rotatably connected with the other end of the first support column 31; the supporting driving member 33 is disposed below the fifth deck 23, the supporting driving member 33 can drive the second support column 32 to rotate relative to the first support column 31, when the supporting driving member 33 drives the second support column 32 to rotate to abut against the third plate 22, the supporting position is the supporting position of the supporting assembly 3, and when the supporting driving member 33 drives the second support column 32 to rotate to disengage from the third plate 22 and be fastened below the fifth deck 23, the receiving position is the supporting assembly 3.

Illustratively, the supporting driving member 33 is a hydraulic cylinder, and the driving force of the hydraulic cylinder is large, so that the driving is more stable, which is beneficial to ensuring that the supporting component 3 supports the fifth deck 23 more reliably.

Preferably, the second prop 32 is provided with a through hole 321, which is beneficial to reduce the weight of the support assembly 3 and thus the mass of the ro-ro passenger ship; on the other hand, the support assembly 3 facilitates the passage of persons on the third deck 22 when supporting the fifth deck 23. Illustratively, to further reduce the weight of the support assembly 3, the first support column 31 is also provided with a through hole 321.

In this embodiment, in order to accommodate the supporting component 3 located at the accommodating position, the locking component 4 is disposed below the fifth deck 23, and when the supporting component 3 is located at the accommodating position, the supporting component 3 is disposed on the locking component 4, so as to reduce the stress on the supporting driving component 33.

Further, the locking assembly 4 includes a locking driving member 41 and a bearing plate 42 disposed at a driving end of the locking driving member 41, when the supporting assembly 3 is located at the receiving position and needs to be supported by the locking assembly 4, the locking driving member 41 can drive the bearing plate 42 to be disposed below the supporting assembly 3 located at the receiving position, so as to provide reliable support for the first pillar 31 and the second pillar 32.

Specifically, in order to ensure the supporting reliability of the supporting component 3 located at the supporting position, the third plate 22 is provided with a stop plate 221, and when the supporting component 3 is located at the supporting position, the stop plate 221 abuts against one end of the second pillar 32 of the supporting component 3, which is far away from the first pillar 31, so as to avoid the sliding of the second pillar 32 caused by the excessive supporting force, and further ensure the supporting reliability.

Optionally, a cross structural beam 231 and a longitudinal structural beam 232 are disposed below the fifth deck 23 and intersect with each other, the longitudinal structural beam 232 extends along the length direction of the ro-ro passenger ship, and the support assembly 3 is disposed on the longitudinal structural beam 232 due to the longer length, which can improve the strength of the fifth deck 23 more effectively.

Further, along the length direction of the ro-ro passenger ship, more than two supporting components 3 are arranged at intervals to ensure that the bearing capacity of each position in the length direction of the ro-passenger ship can be effectively improved.

Preferably, the support members 3 are spaced the same distance from the port side 11 and the starboard side 12 to ensure that the load bearing capacity across the width of the fifth deck 23 is increased to be more uniform and thus to ensure that the forces on the fifth deck 23 are more uniform.
