Description

[Technical Field]

[0001] The present application relates to a boarding bridge that connects the boarding gate side of a passenger terminal at a port with the gangway side of a ship docked at a quay. [Background technology]

[0002] Conventionally, the boarding gate at a port's passenger terminal and the gangway (boarding and disembarking entrance) of a ship docked at the quay are connected by a movable boarding bridge. The height of the gangway of a ship moored at the quay changes depending on conditions such as the ship's size, draft, and tide level. Port boarding bridges also have the ability to follow the movement of the ship's hull due to tides and waves.

[0003] In particular, with the recent increase in the size and diversity of ships, there is a demand for boarding bridges that can accommodate ships with a large difference in elevation between the boarding gate and the gangway. One example of this type of prior art is a boarding bridge filed by the present applicant (see Patent Document 1). This boarding bridge comprises a first structure having a first floor connecting to the boarding gate and a second floor located above the first floor, and a structure having a lift floor connecting to the gangway. The boarding bridge also comprises a lift aisle body connected to the structure so as to be able to lift or lower, and having a lift aisle connecting to a selected one of the first and second floors, and an elevator connecting a first elevator opening on the first floor to a second elevator opening on the lift floor.

[0004] [Patent Document 1] Patent Publication No. 2021-161707 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, boarding bridges have recently been required to be barrier-free, and the boarding bridge of Patent Document 1 is equipped with an elevator. However, when the elevator stops due to a power outage, malfunction, or the like, it may be necessary for passengers to evacuate from the elevator. For this reason, there is a demand for a boarding bridge that makes it easier to evacuate from the elevator in an emergency.

[0006] Therefore, the present application aims to provide a boarding bridge that can accommodate ships (e.g., large passenger ships) where the difference in elevation between the terminal's boarding gate and the ship's gangway is relatively large, and that allows for easy evacuation from the elevator. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the boarding bridge of the present application is a boarding bridge connecting the boarding gate side of a terminal and the gangway side of a ship, and is equipped with a first floor connecting to the boarding gate side, a second floor connecting to the gangway side, a staircase connecting the first floor and the second floor, a plurality of rails connecting the first floor and the second floor, an elevator that moves between the first floor and the second floor along the plurality of rails, and an elevating device that raises and lowers the second floor, wherein the staircase is swingably supported on the first floor by a first support part and swingably supported on the second floor by a second support part, and the plurality of rails are arranged at a distance in the front-to-rear direction and are swingably supported on the first floor by a third support part and swingably supported on the second floor by a fourth support part, with the same fulcrum distance. [Effects of the Invention]

[0008] According to the present application, it is possible to provide a boarding bridge that can accommodate ships with a relatively large difference in elevation between the terminal's boarding gate and the ship's gangway, and that allows for easy evacuation from the elevator.

DETAILED DESCRIPTION OF THE INVENTION

[0010] An embodiment of a boarding bridge according to the present application will be described below with reference to the drawings. In the following description, the boarding gate 90 side of the passenger terminal will be described as being connected to the gangway 100 side of a ship docked at a quay. Furthermore, the concepts of front, rear, left, and right in the following description will be the same as the concepts of front, rear, left, and right when looking from the boarding gate 90 side toward the gangway 100 side, as shown in the plan view of Figure 2.

[0011] <Configuration of the first boarding bridge> FIG. 1 is a side view of the first boarding bridge 1 according to the first embodiment. FIG. 2 is a plan view of the first boarding bridge 1 shown in FIG. 1. FIG. 3 is a view taken along the arrows III-III shown in FIG. 1. FIG. 4 is an enlarged side view showing the ends of the rails 21 and 22 shown in FIG. 1. FIG. 3 shows only the elevator 30 portion as seen along the arrows III-III. FIG. 3 shows the rails 21 and 22 when they are tilted downward.

[0012] As shown in Figures 1 and 2, the first boarding bridge 1 comprises a first floor 2 that connects to the boarding gate 90 side, and a second floor 3 that connects to the gangway 100 side. The first floor 2 has an opening that connects to the floor of the boarding gate 90. A connecting passage 101 is provided between the first floor 2 and the floor of the gangway 100 and the second floor 3, and the second floor 3 has an opening that connects to this connecting passage 101. The first boarding bridge 1 comprises a staircase 10 that connects the first floor 2 and the second floor 3, and a plurality of rails 21 and 22 that connect the first floor 2 and the second floor 3. The plurality of rails 21 and 22 have an elevator 30 at their upper part that moves between the first floor 2 and the second floor 3.

[0013] The first rail 21 and second rail 22 are arranged at a distance from each other in the front-to-rear direction of the elevator 30, which is arranged at a predetermined position on the first floor 2. The first rail 21 extends from a third support portion 23 provided near the front end of the lower part of the elevator 30 toward a fourth support portion 24 on the second floor 3. The second rail 22 extends from the third support portion 23 provided near the rear end of the lower part of the elevator 30 toward the fourth support portion 24 on the second floor 3. The third support portion 23 is supported by a support frame 56. The fourth support portion 24 is supported by a support member 57 provided on the second floor 3.

[0014] The elevator 30 of the first boarding bridge 1 is designed to allow passengers to board and disembark in the front-to-rear direction between the first floor 2 and the second floor 3. The elevator 30 has elevator entrances 32 at the front and rear. Passengers on the first floor 2 board and disembark on the elevator 30 between the elevator boarding and alighting position 2a and the front elevator entrance 32. Passengers on the second floor 3 board and disembark on the elevator 30 between the elevator boarding and alighting position 3a and the rear elevator entrance 32.

[0015] The first floor 2, the second floor 3, the stairs 10, and the multiple rails 21, 22 are provided on a traveling vehicle 50 that moves in the longitudinal direction of the docked ship. The traveling vehicle 50 has wheels 52 that run along ground rails 51 installed on the ground. In this embodiment, the traveling vehicle 50 runs along the ground rails 51 using the wheels 52, but the traveling vehicle 50 may also run on tires without rails. In this embodiment, the traveling vehicle 50 has the wheels 52 driven by a drive machine to move along the ground rails 51. The traveling vehicle 50 has support columns 53, 54 extending upward from the wheels 52 and a beam 55 that connects the support columns 53, 54 horizontally. The first floor 2 is supported by the beam 55. In addition, a support frame 56 that positions the elevator 30 in a predetermined position on the first floor 2 is provided on the beam 55.

[0016] The first floor 2 is fixed at a predetermined height corresponding to the boarding gate 90. The second floor 3 is provided at a predetermined position on the traveling body 50 so as to be able to respond to changes in the height of the gangway 100, as will be described later. The traveling body 50 moves the first floor 2, the second floor 3, the stairs 10, the first rail 21, the second rail 22, and the elevator 30 as a unit.

[0017] The staircase 10 is swingably supported on the first floor 2 by a first support member 11, and swingably supported on the second floor 3 by a second support member 12. The multiple rails 21, 22 are provided with a first rail 21 and a second rail 22 arranged in the left-right direction of the elevator 30, spaced apart horizontally. The multiple first rails 21 and second rails 22 are swingably supported on the first floor 2 by a third support member 23, and swingably supported on the second floor 3 by a fourth support member 24, with the same fulcrum distance L1. In other words, the multiple rails 21, 22 form a link mechanism with the same fulcrum distance L1 in a side view. The elevator 30 has wheels 31 that run on the tops of the first rail 21 and the second rail 22. The wheels 31 are provided at the front and rear ends of the lower part of the elevator 30.

[0018] The first boarding bridge 1 is also provided with an emergency escape deck 35 below the first rail 21. The emergency escape deck 35 is provided parallel to the first rail 21 and moves integrally with the first rail 21. The upper surface of the emergency escape deck 35 is an uneven floor surface 36. The uneven floor surface 36 has recesses that allow passengers to place their feet during an emergency escape. By providing the emergency escape deck 35 below the first rail 21 along which the elevator 30 moves, even if the elevator 30 stops, passengers can easily evacuate from that position via the emergency escape deck 35. The emergency escape deck 35 can be used as a maintenance deck. The top and sides of the elevator 30 may be covered with a cage 37.

[0019] In this embodiment, the traveling machine body 50 is equipped with a lifting device 60 that raises and lowers the second floor 3. The lifting device 60 in this embodiment raises and lowers the second floor 3 along the support pillars 54 toward the gangway 100. The lifting device 60 is equipped with a guide device 61 that guides the second floor 3 vertically along the support pillars 54. The guide device 61 has a ball screw mechanism 62 provided on the support pillars 54. The ball screw mechanism 62 has a ball screw 63 provided along the support pillars 54 and a connecting member 65 that connects the lifting body 64, which rises and lowers along the ball screw 63, to the second floor 3. The second floor 3 rises and lowers integrally with the connecting member 65. The ball screw mechanism 62 rotates the ball screw 63 using a drive device 66 provided at the bottom of the support pillars 54, and the rotation of this ball screw 63 raises and lowers the second floor 3 integrally with the lifting body 64 and the connecting member 65.

[0020] With this lifting device 60, when the ball screw 63 is rotated in one direction by the drive device 66, the second floor 3 can be raised together with the lifting body 64. When the ball screw 63 is rotated in the other direction by the drive device 66, the second floor 3 can be lowered together with the lifting body 64. By using a ball screw mechanism 62 in the lifting device 60, the second floor 3 can be raised and lowered appropriately with little frictional resistance. The ball screw mechanism 62 can use known technology.

[0021] In addition, the lifting device 60 in this embodiment uses a ball screw mechanism 62 to raise and lower the second floor 3, but the lifting device 60 can use various methods other than the ball screw mechanism 62, such as a chain, winch, cylinder, etc., and is not limited to this embodiment.

[0022] In this embodiment, while the second floor 3 moves up and down in the vertical direction, the first rail 21 and the second rail 22 swing up and down on the second floor 3 side around the support axis center P1 of the third support part 23 of the first floor 2. For this reason, the first rail 21 and the second rail 22 have elongated holes 25, 26 for support at the positions of the third support part 23 and the fourth support part 24, thereby absorbing changes in the distance between the supports that occur when the angle is changed. The elongated holes 25, 26 are displacement absorbing parts. The first rail 21 has the elongated hole 25 at the position of the fourth support part 24, and the second rail 22 has the elongated hole 26 at the position of the third support part 23.

[0023] In this embodiment, as shown in FIG. 4 described later, one end of first rail 21 and one end of second rail 22 are provided with arc-shaped portions 27, so that second rail 22 has long holes 25 in the part of third support portion 23 that does not have arc-shaped portion 27 to absorb displacement, and first rail 21 has long holes 26 in the part of fourth support portion 24 that does not have arc-shaped portion 27 to absorb displacement.

[0024] When ascending or descending to the second floor 3, the second floor 3 side of the staircase 10 swings up and down around the first support part 11 on the first floor 2. For this reason, the second support part 12 of the staircase 10 is positioned as a long hole 13, which acts as a displacement absorbing part, thereby absorbing the change in the distance between the supports that occurs when ascending or descending to the second floor 3.

[0025] 3, in this embodiment, first rail 21 is disposed on the inner side of elevator 30 in the left-right direction, and second rail 22 is disposed on the outer side of elevator 30 in the left-right direction. First rail 21 and second rail 22 are disposed with a lateral offset so as not to interfere with each other when changing the angle.

[0026] The wheels 31 of the elevator 30, which run on the upper part of the first rail 21, are supported by a first bracket 33 provided at the bottom of the elevator 30. On the other hand, the wheels 31, which run on the upper part of the second rail 22, are supported by a second bracket 34 provided at the vertical middle part of the elevator 30 so as to straddle the first rail 21.

[0027] As shown in FIGS. 1 and 2 , in this embodiment, the first rail 21 is provided with an elevator movement device 40 that moves the elevator 30 along the rails 21 and 22. The elevator movement device 40 in this embodiment has a drive sprocket 41 provided at an end of the first rail 21 that protrudes further toward the boarding gate 90 than the third support portion 23, and a driven sprocket 42 provided at an end of the first rail 21 toward the gangway 100. A drive chain 44 is looped between the drive sprocket 41 and the driven sprocket 42. Tension is maintained in the drive chain 44 by a tension sprocket 43. As shown in FIG. 3 , the drive sprockets 41 of the first rail 21 provided at left and right positions of the elevator 30 are connected by a drive shaft 45, and the driven sprocket 42, not shown, is rotatably supported by the first rail 21. The drive shaft 45 is rotationally driven by a drive motor 46 provided on the first rail 21. The drive motor 46 is shown in FIGS.

[0028] The elevator 30 is connected to a predetermined position of the drive chain 44, and moves on the rails 21, 22 by the wheels 31 by driving the drive motor 46 to rotate the drive chain 44. The elevator 30 moves between the elevator boarding and alighting position 2a on the first floor 2 and the elevator boarding and alighting position 3a on the second floor 3.

[0029] As shown in FIG. 4, the second rail 22 has an arc-shaped portion 27 on the upper surface of its end at the position of the fourth support portion 24 supporting it on the second floor 3, with the distance R1 from the support axis center P2 being constant. The first rail 21 (FIG. 1) has an arc-shaped portion 27 on the upper surface of its end at the position of the third support portion 23 supporting it on the first floor 2, with the distance R1 (FIG. 4) from the support axis center P1 (FIG. 1) being constant. As a result, even if the angle between the first rail 21 and the second rail 22 changes, the arc-shaped portions 27 of the third support portion 23 and the fourth support portion 24 can maintain constant the distance R1 from the support axis center P1 to the upper surface of the first rail 21 and the distance R1 from the support axis center P2 to the center of the wheel 31 moving on the upper surface of the second rail 22. Therefore, even if the angle between the first rail 21 and the second rail 22 changes, the distances between the floor surfaces of the elevator 30, the first floor 2, and the second floor 3 can be made substantially the same. That is, it is possible to create a barrier-free state between the elevator 30 and the first floor 2 and the second floor 3. At the end of the arc-shaped portion 27 of the second rail 22, a stopper 28 for the wheel 31 is provided.

[0030] <Functions of the first boarding bridge> As shown in FIGS. 1 and 2 , the first boarding bridge 1 is moved by the traveling vehicle 50 to a position between a predetermined boarding gate 90 and a predetermined gangway 100. The first floor 2 is connected to the boarding gate 90 side. The second floor 3 is raised and lowered by the lifting device 60 according to the height of the gangway 100. In this embodiment, the second floor 3 can be maintained at a predetermined height by stopping the rotation of the ball screw 63 of the lifting device 60. When the second floor 3 is raised or lowered, the angles between the stairs 10 and the first and second rails 21 and 22 change accordingly. After the second floor 3 is maintained at a predetermined height, a connecting passage 101 is provided between the second floor 3 and the gangway 100, and the second floor 3 and the gangway 100 are connected via this connecting passage 101. The connecting passage 101 can be, for example, an extendable walkway.

[0031] Because the first rail 21 and the second rail 22 are supported at the same fulcrum distance L1, they always remain parallel even if the angle is changed. The first rail 21 and the second rail 22 shown in solid lines in FIG. 1 indicate the state when the second floor 3 is moved upward. The first rail 21 and the second rail 22 shown in dashed double-dashed lines in FIG. 1 indicate the state when the second floor 3 is moved downward. In this way, even if the angle of the first rail 21 and the second rail 22 is changed, the elevator 30 can always move in a horizontal state. In other words, the elevator 30 functions as an inclined elevator.

[0032] According to this first boarding bridge 1, passengers can board the elevator 30 on the first floor 2 on the boarding gate 90 side, and travel in the elevator 30 to the second floor 3. The elevator 30 can move horizontally between the first floor 2 and the second floor 3 along the first rail 21 and the second rail 22, which are inclined at a predetermined angle. When the elevator 30 is moved to the first floor 2 or the second floor 3, the floor surface of the elevator 30 can be made substantially flush with the level of the first floor 2 or the second floor 3 because the first rail 21 and the second rail 22 have arc-shaped portions 27 at their ends.

[0033] On the other hand, even if the elevator 30 stops due to an electrical fault or the like while it is moving along the first rail 21 and the second rail 22, since the stairs 10 are located to the side of the elevator 30, it is possible to easily evacuate from the elevator 30 to the stairs 10 in such an emergency. Furthermore, in this embodiment, since the emergency escape deck 35 is provided below the first rail 21 along which the elevator 30 moves, it is also possible to evacuate from the elevator 30 to the emergency escape deck 35 in the event that the elevator 30 stops. Therefore, the first boarding bridge 1 can be used on ships with a relatively large difference in elevation between the boarding gate 90 and the ship's gangway 100, and it is also possible to easily evacuate from the elevator 30.

[0034] <Configuration of the second boarding bridge> FIG. 5 is a side view of a second boarding bridge 5 according to the second embodiment. FIG. 6 is a plan view of the second boarding bridge 5 shown in FIG. 5. The second boarding bridge 5 is an example in which the boarding and disembarking portion of the elevator 30 is different from the first boarding bridge 1 described above. Note that the explanation of the second boarding bridge 5 will only cover the configuration that differs from the first boarding bridge 1. Furthermore, the same components as those of the first boarding bridge 1 are given the same reference numerals as those of the first boarding bridge 1, and their explanation will be omitted.

[0035] The second boarding bridge 5 is configured so that passengers board and disembark from the left and right sides of the elevator 70 between the first floor 6 and the second floor 7. The second boarding bridge 5 is configured so that passengers board and disembark from the right side, where stairs 10 are located, relative to the elevator 70. The first floor 6 is provided with an elevator boarding and disembarking position 6a for boarding and disembarking from the right side of the elevator 70. The second floor 7 is provided with an elevator boarding and disembarking position 7a for boarding and disembarking from the right side of the elevator 70.

[0036] An elevator entrance 72 for boarding and alighting between elevator boarding and alighting positions 6a and 7a is provided on the right side of the elevator 70. Furthermore, a pedestal 77 is provided at the bottom of the elevator 70 to avoid interference when the gangway 100 side of the first rail 21 is tilted upward. Wheels 71 are provided at the front and rear ends of the bottom of the pedestal 77. Similar to the first boarding bridge 1, the wheels 71 are provided at the bottom of first brackets 73 provided on the left and right sides of the pedestal 77, and at the bottom of second brackets 74 provided on the left and right sides so as to straddle the first rail 21 from the pedestal 77.

[0037] In the second boarding bridge 5, the first rail 21 and the second rail 22 are positioned away from the stairs 10, and therefore an emergency escape deck 75 is provided between the first rail 21, the second rail 22, and the stairs 10. The emergency escape deck 75 is provided parallel to the first rail 21 and the second rail 22. The upper surface of the emergency escape deck 75 is an uneven floor surface 76. One end of the emergency escape deck 75 is rotatably supported on the first floor 6, and the other end is rotatably supported on the second floor 7. The first floor 6 is provided with an opening / closing door 6b for evacuating from the emergency escape deck 75. In this embodiment, a long hole 78 is provided in the support portion of the second floor 7 that supports the emergency escape deck 75, absorbing changes in the distance between the supports when the emergency escape deck 75 swings around the support portion of the first floor 6. The configuration of other components, such as the stairs 10, the elevator movement device 40, the traveling body 50, and the lifting device 60, is the same as that of the first boarding bridge 1 described above, and therefore description of these components will be omitted.

[0038] <Functions of the second boarding bridge> The second boarding bridge 5 is moved by the traveling vehicle 50 to a position between a predetermined boarding gate 90 and a predetermined gangway 100. The first floor 6 is connected to the boarding gate 90 side. The second floor 7 is raised and lowered by the lifting device 60 according to the height of the gangway 100. When the second floor 7 is raised or lowered, the angles of the stairs 10 and the emergency escape deck 75, the first rail 21, and the second rail 22 change accordingly. After the second floor 7 is maintained at a predetermined height, a connecting passage 101 is provided between the second floor 7 and the gangway 100, and the second floor 7 and the gangway 100 are connected via this connecting passage 101.

[0039] Because the first rail 21 and the second rail 22 are supported at the same fulcrum distance L1, they always remain parallel even if the angle is changed. The first rail 21 and the second rail 22 shown in solid lines in Fig. 5 show the state when the second floor 7 is moved upward. The first rail 21 and the second rail 22 shown in two-dot chain lines in Fig. 5 show the state when the second floor 7 is moved downward. In this way, even if the angle of the first rail 21 and the second rail 22 is changed, the elevator 70 can always move in a horizontal state.

[0040] With this second boarding bridge 5, passengers can board the elevator 70 on the first floor 6 on the boarding gate 90 side and travel to the second floor 7 by elevator 70. The elevator 70 can travel horizontally between the first floor 6 and the second floor 7 along the first rail 21 and the second rail 22, which are inclined at a predetermined angle. When the elevator 70 is moved to the first floor 6 or the second floor 7, the floor surface of the elevator 70 can be made substantially flush with the level of the first floor 6 or the second floor 7 because the arc-shaped portions 27 are provided at the ends of the first rail 21 and the second rail 22.

[0041] On the other hand, even if the elevator 70 stops due to an electrical fault or the like while moving along the first rail 21 and the second rail 22, because there is an emergency escape deck 75 to the side of the elevator 70, in such an emergency, passengers can easily evacuate from the elevator 70 to the emergency escape deck 75. Therefore, the second boarding bridge 5 can also accommodate ships with a relatively large difference in elevation between the boarding gate 90 and the ship's gangway 100, and makes it easy to evacuate from the elevator 70.

[0042] <Configuration of the 3rd boarding bridge> FIG. 7 is a side view of a third boarding bridge 9 according to the third embodiment. FIG. 8 is a plan view of the third boarding bridge 9 shown in FIG. 7. The third boarding bridge 9 is an example that differs from the first boarding bridge 1 described above in the configuration for raising and lowering the second floor 3. Note that the explanation of the third boarding bridge 9 will only focus on the configuration that differs from the first boarding bridge 1. Furthermore, the same components as the first boarding bridge 1 will be assigned the same reference numerals as the first boarding bridge 1, and their explanation will be omitted.

[0043] The third boarding bridge 9 is configured to raise and lower the second floor 3 using a first rail 21 and a second rail 22. In the third boarding bridge 9, the second floor 3 is supported by fourth support parts 24 of the first rail 21 and the second rail 22. Because the third boarding bridge 9 is configured to raise and lower the second floor 3 using the first rail 21 and the second rail 22, it is equipped with an elevating device 80 that is different from the elevating device 60 in the first boarding bridge 1. The running body 50 has lower heights of its supports 54.

[0044] The lifting device 80 of the third boarding bridge 9 has a tilting device 81 that swings the plurality of first rails 21 and second rails 22 around the support shaft center P1 of the third support section 23 as a fulcrum. The tilting device 81 has a telescopic jack 82 that changes the elevation angle of the plurality of rails 21, 22. The rear end of the telescopic jack 82 is supported by the beam 55 of the traveling body 50, and the front end is connected to the longitudinal middle portion of the first rail 21. The telescopic jack 82 extends and retracts to change the angle of the first rail 21 around the support shaft center P1 of the third support section 23 as a fulcrum. The configuration of the other components, such as the staircase 10, elevator movement device 40, first floor 2, second floor 3, and elevator 30, is the same as that of the first boarding bridge 1 described above, so a description of these components will be omitted.

[0045] <Functions of the 3rd boarding bridge> The third boarding bridge 9 is moved by the traveling vehicle 50 to a position between a predetermined boarding gate 90 and a predetermined gangway 100. The first floor 2 is connected to the boarding gate 90 side. The second floor 3 is raised or lowered to a height corresponding to the height of the gangway 100 by changing the angle of the first rail 21 using the telescopic jack 82 of the lifting device 80. The height of the second floor 3 can be changed while maintaining a horizontal state because the first rail 21 and the second rail 22 are supported by the third support part 23 at the same fulcrum distance L1. After the second floor 3 is maintained at a predetermined height, a connecting passage 101 is provided between the second floor 3 and the gangway 100, and the second floor 3 and the gangway 100 are connected via this connecting passage 101.

[0046] When the elevator 70 moves up and down the second floor 3, the first rail 21 and the second rail 22 are supported at the same fulcrum distance L1, so they always remain parallel even if the angle is changed. The first rail 21, the second rail 22, and the second floor 3 shown in solid lines in Fig. 7 indicate the state when the second floor 3 is moved upward. The first rail 21, the second rail 22, and the second floor 3 shown in dashed double-dashed lines in Fig. 7 indicate the state when the second floor 7 is moved downward. In this way, even if the angle of the first rail 21 and the second rail 22 is changed, the elevator 70 always moves in a horizontal state.

[0047] With this third boarding bridge 9, passengers can board the elevator 30 on the first floor 2 on the boarding gate 90 side, and travel in the elevator 30 to the second floor 3. The elevator 30 can move horizontally between the first floor 2 and the second floor 3 along the first rail 21 and the second rail 22, which are inclined at a predetermined angle. When the elevator 30 is moved to the first floor 2 or the second floor 7, the floor surface of the elevator 30 can be made substantially flush with the level of the first floor 2 or the second floor 3 because the arc-shaped portions 27 are provided at the ends of the first rail 21 and the second rail 22.

[0048] On the other hand, even if the elevator 30 stops due to an electrical fault or the like while moving along the first rail 21 and the second rail 22, there are stairs 10 to the side of the elevator 30 and an emergency escape deck 35 below, so in such an emergency, people can easily evacuate from the elevator 30 to the emergency escape deck 35. Therefore, the third boarding bridge 9 can also be used on ships with a relatively large difference in elevation between the boarding gate 90 and the ship's gangway 100, and makes it easy to evacuate from the elevator 30.

[0049] <Other variations> The above-described embodiment shows one example, and the configuration for moving the elevator 30 between the first floor 2 and the second floor 3 is one example. Other configurations for moving the elevator 30 are also possible, and various changes to the configuration may be made without departing from the spirit of the present application, and the present application is not limited to the above-described embodiment.

[0050] Furthermore, in the above-described embodiment, a configuration having a traveling body 50 that moves in the longitudinal direction of the ship was described, but a configuration without a traveling body 50 is also possible, and the present application is not limited to the above-described embodiment.

[0051] <Summary> The first boarding bridge according to the present application is a boarding bridge connecting a boarding gate 90 side of a terminal and a gangway 100 side of a ship, and includes a first floor 2 connecting to the boarding gate 90 side, a second floor 3 connecting to the gangway 100 side, a staircase 10 connecting the first floor 2 and the second floor 3, a plurality of rails 21, 22 connecting the first floor 2 and the second floor 3, and an elevator that moves between the first floor 2 and the second floor 3 along the plurality of rails 21, 22. The staircase 10 is swingably supported on the first floor 2 by a first support part 11 and swingably supported on the second floor 3 by a second support part 12, and the multiple rails 21, 22 are arranged spaced apart in the front-to-rear direction, and are swingably supported on the first floor 2 by a third support part 23 and swingably supported on the second floor 3 by a fourth support part 24 at the same fulcrum distance L1.

[0052] With this configuration, stairs 10 and multiple rails 21, 22 along which elevator 30 moves are provided between first floor 2, which connects to boarding gate 90, and second floor 3, which connects to gangway 100. By adjusting the height of second floor 3, the angle between stairs 10 and rails 21, 22 can be changed, and elevator 30 can move from first floor 2 to second floor 3 along rails 21, 22 with the changed angle. This makes it possible to accommodate ships with a relatively large difference in elevation between boarding gate 90 and gangway 100, and also allows passengers to easily evacuate from elevator 30 to stairs 10 in an emergency.

[0053] Furthermore, an emergency escape deck 35 may be provided in parallel with the plurality of rails 21, 22 on the first boarding bridge.

[0054] With this configuration, it is easy to transfer from the elevator 30 moving along the multiple rails 21, 22 to the emergency escape deck 35 and escape.

[0055] In addition, in the first or second boarding bridge, the multiple rails 21, 22 may be arranged to guide the front and rear ends of the lower part of the elevator 30 between the first floor 2 and the second floor 3.

[0056] With this configuration, the position on the first floor 2 where the elevator 30 enters can be used as the base point for the multiple rails 21, 22, and the elevator 30 can be moved appropriately along the rails 21, 22 that extend to the second floor 3.

[0057] In addition, in the third boarding bridge, the elevator 30 may have a plurality of wheels 31 that move along the plurality of rails 21, 22, and the plurality of rails 21, 22 may have an elevator moving device 40 that moves the elevator 30 along the plurality of rails 21, 22.

[0058] With this configuration, the elevator 30 can move on the rails 21 and 22 with the wheels 31 using the elevator movement device 40.

[0059] In addition, in the fourth boarding bridge, the elevator 30 is configured so that the plurality of wheels 31 move along the upper surfaces of the plurality of rails 21, 22, and the plurality of rails 21, 22 may have arc-shaped portions 27 on the upper surfaces of the third support portion 23 and the fourth support portion 24, respectively, the arc-shaped portions 27 being at a constant distance R1 from the support axis centers P1 of the third support portion 23 and the fourth support portion 24.

[0060] With this configuration, even if the angle of the rails 21, 22 changes, the height from the support shaft center P1 to the wheel 31 remains constant due to the arc-shaped portion 27, so the floor surface of the second floor 3 and the floor surface of the elevator 30 can be made substantially flush with each other. This makes it possible to reduce the step between the elevator 30 and the second floor 3.

[0061] Furthermore, in any of the first to fifth boarding bridges, the lifting device 60 has a guide device 61 that guides the second floor 3 vertically, and the first support portion 11 or the second support portion 12 that supports the stairs 10 and the third support portion 23 or the fourth support portion 24 that supports the multiple rails 21, 22 may each have a displacement absorption portion that absorbs changes in the distance between the supports that occur when the second floor 3 is raised or lowered.

[0062] With this configuration, the displacement absorbing section absorbs changes in the distance between the supports of the multiple rails 21, 22 that occur when the second floor 3 is moved vertically by the lifting device 60 to adjust its height. Therefore, the angles of the multiple rails 21, 22 can be appropriately changed in accordance with the height adjustment of the second floor 3.

[0063] In addition, in the sixth boarding bridge, the guide device 61 may have a vertically arranged ball screw mechanism 62 and a connecting member 65 that connects a lifting body 64 raised and lowered by the ball screw mechanism 62 to the second floor 3.

[0064] With this configuration, the second floor 3 can be raised and lowered appropriately with little frictional resistance from the ball screw mechanism 62.

[0065] Furthermore, in any of the first to fifth boarding bridges, the lifting device 80 may have a tilting device 81 that swings the plurality of first rails 21 or second rails 22 around the support axis center P1 of the third support part 23 as a fulcrum, and the tilting device 81 may have an extendable jack 82 that changes the tilt angle of the plurality of rails 21, 22.

[0066] With this configuration, the angle of the rails 21, 22 can be changed using the telescopic jack 82 of the lifting device 60, thereby making it possible to appropriately adjust the height of the second floor 3 and change the angle of the rails 21, 22.

[0067] In addition, in any of the first to seventh boarding bridges, the stairs 10 may be configured as variable-angle stairs.

[0068] With this configuration, even if the angle of the stairs 10 changes due to the height adjustment of the second floor 3, the treads of the stairs 10 can be kept appropriate. [Explanation of symbols]
