[0041] like Figure 1 The hull 2000 has a boarding deck 2001; in a preferred embodiment, the hull 2000 is also provided with a boarding door 2003 at the boarding deck 2001, and personnel board the ship at the boarding deck 2001 after passing through the boarding door 2003; a reinforcement 2002 is provided on the boarding deck 2001, and the boarding deck 2001 can be understood as a component composed of a flat plate and a reinforcement structure; the hull 2000 has an outer plate 2004 located below the boarding deck 2001, and the outer plate 2004 can be understood as a side part of the outer shell of the hull 2000; in a preferred embodiment, the hull 2000 has a storage room 2005 arranged below the boarding deck 2001, and the gangway system 1000 can be stored in the storage room 2005. In other embodiments, when the storage room 2005 is not provided, the gangway system 1000 can be stored to the outside of the outer shell of the hull 2000.

[0042] like Figure 1 In a preferred embodiment, the hull 2000 further includes a storage door 2006, the lower end of which is hinged to the outer plate 2004 via a sixth pin 2007, and the ship further includes a door opening device, which includes a winch 3001 and a traction rope 3002, the winch 3001 is arranged on the top of the storage room 2005, below the embarkation deck 2001, the traction rope 3002 is a steel wire rope, one end of which is wound around the winch 3001, and the other end is connected to the upper end of the storage door 2006, and the winch 3001 drives the traction rope 3002 to be retracted and released to open or close the storage door 2006. It can be understood that the upper end and the lower end of the storage door 2006 refer to the corresponding upper end and the lower end when the storage door 2006 is closed.

[0043] like Figure 1 , Figure 2The gangway system 1000 includes a gangway 1 part and a power part. The gangway 1 has three sections of ladder 11, which are the first section 111, the second section 112, and the third section 113 from top to bottom. The first section 111 and the second section 112 are rotatably hinged at the adjacent part through the second pin shaft 132, and the second section 112 and the third section 113 are rotatably hinged at the adjacent part through the third pin shaft 133, so that two adjacent sections of ladder 11 can rotate relative to each other to unfold or fold. Two adjacent sections of ladder 11 are connected at the adjacent part, making the structure compact. When the gangway 1 is unfolded to the boarding state, the three sections of ladder 11 are basically parallel, such as Figure 1 When the gangway ladder 1 is stored in the storage room 2005, the three sections of the ladder 11 are folded together, as shown Figure 3 The description of the extension direction, up and down of the structure of the gangway 1 in the present invention can be understood as the extension direction, up and down of the gangway 1 when it is in the boarding state. In other embodiments, the number of sections of the ladder 11 can be adjusted according to the boarding height requirement and the space size of the storage room 2005, and at least the first ladder section 111 is provided.

[0044] The first stair section 111 is provided with a first pin 131 at the upper end thereof. The first stair section 111 is rotatably hinged with the embarkation deck 2001 through the first pin 131, specifically, hinged with the reinforcement 2002 of the embarkation deck 2001. The portion of the first stair section 111 on which the first pin 131 is installed is the first transition portion. By rotating the first stair section 111 relative to the embarkation deck 2001, the gangway 1 can be rotated to the outside of the storage room 2005 to be in a boarding state, or to the inside of the storage room 2005 to be in a storage state. Specifically, the first pin 131 is provided at the top of the first stair section 111 and is located at the outer end of the embarkation deck 2001, so that the first stair section 111 is just adjacent to the embarkation deck 2001, and the structure is compact and convenient for boarding.

[0045] The power part includes four hydraulic cylinders, namely the first hydraulic cylinder 21, the second hydraulic cylinder 22, the third hydraulic cylinder 23, and the fourth hydraulic cylinder 24. The first hydraulic cylinder 21 and the second hydraulic cylinder 22 are both used as the first power device, and their piston rods are used as the first moving parts to drive the first stair segment 111; the third hydraulic cylinder 23 and the fourth hydraulic cylinder 24 are both second power devices, and their piston rods are used as the second moving parts to drive the second stair segment 112 and the third stair segment 113 respectively.

[0046] Specifically, Figure 1 , Figure 2The first hydraulic cylinder 21 and the second hydraulic cylinder 22 are arranged in the storage room 2005, below the first stair section 111, the piston rods of the two hydraulic cylinders extend in a direction not parallel to the first stair section 111, and are rotatably hinged to the bottom of the first stair section 111 through the fourth pin 134, the fifth pin 135 and the first stair section 111 respectively, and the piston rods of the two hydraulic cylinders move along the extension direction of the piston rods to drive the first stair section 111 to rotate around the first pin 131, the movement of the piston rods of the two hydraulic cylinders toward the direction of the first stair section 111 can push the first stair section 111 to rotate outside the storage room 2005 to the boarding state, and the movement in the direction away from the first stair section 111 can pull the first stair section 111 to rotate into the storage room 2005 to the storage state.

[0047] The piston rods of the first hydraulic cylinder 21 and the second hydraulic cylinder 22 extend obliquely upward. In the boarding state, an oblique upward supporting force is applied to the first step 111, so that the force between the two piston rods and the first step 111 is good; in other embodiments, when it is set to extend in the horizontal direction, the force condition is also good. The two hydraulic cylinders are arranged at intervals along the extension direction of the first gangway 1 to form multi-point support for the first step 111, which can reduce the force between the two hydraulic cylinders and the first step 111 and improve the force condition. Further, the piston rods of the two hydraulic cylinders are arranged in parallel to simplify the control. In other embodiments, the first moving parts of the multiple first power devices used to drive the first step 111 may not be arranged in parallel.

[0048] like Figure 1 , Figure 2 The third hydraulic cylinder 23 is arranged on the upper surface of the first stair section 111, and its piston rod is arranged along the extension direction of the first stair section 111 toward the second stair section 112. The piston rod of the third hydraulic cylinder 23 abuts against the second stair section 112 and moves toward the second stair section 112 to push the second stair section 112 to rotate around the second pin shaft 132 until it is parallel to the first stair section 111 to the boarding state; the piston rod of the third hydraulic cylinder 23 retracts to the outside of the second stair section 112 in the direction away from the second stair section 112, so that the second stair section 112 can rotate around the second pin shaft 132 and be folded with the first stair section 111 until it is in the storage state. The second stair section 112 can be folded manually; or the second stair section 112 can be automatically folded by additionally setting up a winch and a steel cable; or a slide groove can be set on the second stair section 112, and the piston rod of the third hydraulic cylinder 23 can be installed in the slide groove. When the piston rod of the third hydraulic cylinder 23 retracts, the second stair section 112 can be automatically driven to fold relative to the first stair section 111.

[0049] like Figure 1 , Figure 2The fourth hydraulic cylinder 24 is disposed on the lower surface of the second stair segment 112, and its piston rod extends along the extension direction of the second stair segment 112 and is disposed toward the third stair segment 113. The principle of the fourth hydraulic cylinder 24 driving the third stair segment 113 to expand relative to the second stair segment 112 is the same as the principle of the third hydraulic cylinder 23 driving the second stair segment 112 to expand relative to the first stair segment 111, which will not be repeated here.

[0050] In this embodiment, in the power part, the first power device and the second power device both use hydraulic cylinders, which is convenient for using a set of hydraulic systems, making the structure simple and the cost low. In other embodiments, the first power device and the second power device can use cylinders; or use motors as power sources, and use racks in gear rack mechanisms, screws or nuts in screw nut mechanisms, etc. as the first moving member and the second moving member.

[0051] like Figure 1 , Figure 2 Each ladder 11 is provided with a handrail 12, and the handrail 12 is rotatably connected to the ladder 11 through a pin arranged along the extension direction of the ladder 11, so that the handrail 12 can be folded toward the middle of the ladder 11 on the surface of the ladder 11. In other embodiments, the handrail 12 can be detachably arranged relative to the ladder 11. After the boarding is completed, the handrail 12 is removed, so that the ladder 11 is folded and stored in the storage room 2005. The state of the handrail 12 after removal is as follows: Figure 4 , Figure 5 shown.

[0052] The gangway system 1000 provided in the present invention can reduce the occupancy of the corridor by the storage of the gangway 1, and improve the degree of automation, reduce manual participation, and simplify the operation work.
