Description

Boarding bridge

The present invention relates to a boarding bridge. In particular, the present invention relates to an improved connection structure between a boarding bridge and a boarding / alighting part of a moving body (for example, an aircraft).

A boarding bridge is known as a facility for passengers getting on and off between an airport terminal building and an aircraft. When the boarding bridge is connected to the boarding / alighting part of the aircraft, a passage to the aircraft is formed using the boarding bridge. As a result, passengers can get on and off directly between the terminal building and the aircraft.

By the way, the lower end of the door of the boarding / alighting part of the aircraft is located below the floor part of the boarding / alighting part of the aircraft, so if the step between the flooring of the boarding / alighting part and the boarding bridge is eliminated, this door It will be difficult to open and close the door by hitting the boarding bridge.

For this reason, it is necessary to make the position of the boarding bridge lower than the position of the floor part of the boarding / alighting part, for example, about several hundreds of millimeters. However, in this case, the level difference between the floor portion of the boarding / alighting portion and the passage of the boarding bridge may be an obstacle to passengers getting on / off. For example, it is not easy for a passenger in a wheelchair to board an aircraft from a terminal due to the presence of such a step.

Therefore, a structure in which an elevating passage is provided at the tip of the boarding bridge separately from the fixed passage of the boarding bridge and the elevating passage can be raised and lowered has already been proposed (see Patent Document 1).

In the boarding bridge of Patent Document 1, the tip of the boarding bridge can be connected to the aircraft in a state where the elevation path of the boarding bridge is located below the floor of the boarding / alighting part. Thereby, the door of the boarding / alighting part of an aircraft can be opened and closed. And after a door opens completely, the raising / lowering channel | path of a boarding bridge is lifted to the substantially same height as the floor part of a boarding / alighting part. Then, since the level | step difference between the floor part of a boarding / alighting part and the raising / lowering channel | path of a boarding bridge is lose | eliminated, the passenger (for example, the passenger who got on the wheelchair) can get down to the raising / lowering channel | path easily from an aircraft. Next, the elevation passage of the boarding bridge is lowered to substantially the same height as the fixed passage of the boarding bridge. Then, since the level | step difference between the fixed passage of a boarding bridge and the raising / lowering passage of a boarding bridge is lose | eliminated, a passenger can move easily toward the terminal of the boarding bridge passage.

JP 2004-155257 A

However, in the boarding bridge of Patent Document 1, it is necessary to ascend and descend the elevating passage every time passengers get on and off the aircraft, so that passengers can get on and off smoothly. Therefore, the technique described in Patent Literature 1 still has room for improvement in terms of smooth passenger boarding / exiting.

The present invention has been made in view of such circumstances, a boarding bridge that can eliminate a step from the boarding / alighting part of a moving body, and allows passengers to get on and off smoothly between the terminal and the moving body. The purpose is to provide.

In order to solve the above problems, the present invention provides:
A walkway,
An elevating deck provided in the plane of the walking path in plan view and used for connection with a boarding / exiting part of a moving body;
An elevating mechanism for elevating the elevating deck;
The fixed end portion is connected to the elevating deck using a connecting swing shaft, and the free end portion is supported on the walking path, and a driven slope,
With
A boarding bridge in which the driven slope forms an inclined path between the lifting deck and the walking path by rotating the driven slope about the connecting swing shaft as the lifting deck moves. To do.

As a result, the step with the boarding / alighting part of the moving body can be eliminated and, for example, it is not necessary to move up and down the elevator deck every time a passenger on a wheelchair gets in or out of the aircraft. You can get on and off smoothly with your body.

Also, in the above boarding bridge, the height of the lifting deck can be adjusted by a simple lifting movement of the lifting deck, so that the floor of the lifting deck can be maintained substantially horizontal without being inclined. For this reason, there exists an advantage that it is easy to position with the raising / lowering deck and the floor part of a boarding / alighting part.

In the boarding bridge of the present invention, the elevating deck may include a slide mechanism that slides in the direction of human traffic. And the said raising / lowering deck may be comprised so that it may contact | abut to the said boarding / alighting part by the said slide mechanism while moving to the same height as the floor part of the said boarding / alighting part by the said raising / lowering mechanism.

With the above configuration, even when a slight gap is generated between the lifting deck and the boarding / exiting part (outer wall) of the moving body, the sliding mechanism can slide to the position where it comes into contact with the boarding / exiting part. Such a gap can also be eliminated.

Further, in the boarding bridge of the present invention, the slide mechanism may be configured to be able to urge the elevating deck against the boarding / alighting portion at a position where the elevating deck contacts the boarding / alighting unit.

With the above configuration, in the boarding bridge of the present invention, even if the gap between the lifting deck and the boarding / exiting portion (outer wall) of the moving body varies due to the ups and downs of the moving body as passengers get on and off, the sliding mechanism Due to the urging action, the elevating deck can be moved in the front-rear direction in accordance with the ups and downs of the moving body, so that the generation of the gap can be appropriately prevented.

In the boarding bridge of the present invention, the walking passage includes an inclined floor that adjusts an inclination in the width direction of the elevating deck and the driven slope, and an inclination mechanism that can incline the inclined floor in the width direction. Also good. And when the said inclined floor is planarly viewed, you may attach the said raising / lowering deck and the said driven slope in the surface of the said inclined floor.

This makes it possible to use a sloped floor to make the two parallel to each other when the edge of the floor of the lifting deck and the edge of the floor of the moving body getting on and off are not parallel.

In particular, in the boarding bridge according to the present invention, even when the drive column of the boarding bridge is being moved, parallel adjustment between the lifting deck and the boarding / unloading section can be performed by the inclined floor, so that the connecting operation of the lifting deck to the boarding / unloading section can be performed efficiently. .

Further, in the boarding bridge of the present invention, the elevating deck includes a floor plate connected to the driven slope using the coupling swing shaft, a damper connected to the floor plate via a rotation shaft, the floor plate, and the floor plate And an elastic plate arranged so as to straddle between the dampers. One end of the elastic plate is fixed to the damper, the other end of the elastic plate is fixed to the floor plate, and the elastic plate is rotated by rotation of the damper around the rotation axis. May be inclined in the width direction of the elevating deck.

Therefore, when the edge of the floor of the lifting deck and the edge of the floor portion of the moving body getting on and off are not parallel, the shift between them can be easily absorbed using the elastic plate.

Further, in the boarding bridge of the present invention, the elevating deck includes a floor plate connected to the driven slope using the connecting swing shaft, and a slide floor that is supported by the floor plate and slides in the direction of human traffic. Also good. And the said slide floor may contact | abut on the said boarding / alighting part.

With the above configuration, even when a slight gap is generated between the lifting deck and the boarding / exiting part (outer wall) of the moving body, the sliding floor can be slid to a position where it comes into contact with the boarding / exiting part, so that the gap can be eliminated. Moreover, since it is not necessary to slide a driven slope largely according to the sliding motion of a slide floor, the support structure and sliding structure of the free end part of a driven slope can be simplified.

The above object, other objects, features, and advantages of the present invention will become apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings.

According to the present invention, it is possible to obtain a boarding bridge that can eliminate a level difference from a boarding / alighting part of a moving body and that passengers can get on and off smoothly between the terminal and the moving body.

FIG. 1 is a layout diagram illustrating an example of a boarding bridge system including a boarding bridge according to an embodiment of the present invention.

As shown in FIG. 1, an air passenger boarding bridge system 1 includes an air passenger boarding bridge 20 (hereinafter abbreviated as “boarding bridge 20”) connected to an entrance of an airport terminal building 10. In the aircraft 11, by using such a boarding bridge 20, there are cases where passengers get on and off efficiently.

FIG. 2 is a diagram showing the overall configuration of the boarding bridge according to the embodiment of the present invention.

2 (the same applies to FIGS. 3, 4, 6, 7, 8, 9, and 10), for convenience, the aircraft 11 side of the boarding bridge 20 is referred to as “front”, and the terminal of the boarding bridge 20 is used. The building 10 side is “rear”. Further, the width direction 300 of the boarding bridge 20 is defined as “left” and “right” of the boarding bridge 20. Moreover, in the following description, there are cases in which the “passing direction 200” of the passerby (passenger) of the boarding bridge 20 in the front-rear direction 200 may be mentioned.

As shown in FIG. 2, the boarding bridge 20 is disposed at the rotander (rear circular chamber) 24 connected to the entrance 10 A of the terminal building 10, the tunnel portion 25 connected to the rotander 24, and the front end of the tunnel portion 25. A cab (front circular chamber) 26 and an auxiliary staircase 23 disposed on the side wall of the tunnel portion 25 in the vicinity of the cab 26.

The rotander 24 is arranged so that the tunnel portion 25 can swing around a shaft 24A (hereinafter referred to as “vertical axis”) in the vertical direction (perpendicular to the plane of FIG. 2). Arranged for rotation at the end. As a result, the rotander 24 can serve as a seam between the terminal building 10 and the tunnel portion 25.

The cab 26 is rotatably arranged at the front end portion of the tunnel portion 25 so that the front end portion of the cab 26 can swing to the left and right by the cab 26 itself turning around the vertical axis 26A.
In this cab 26, an operation panel 30 (see FIG. 3) is installed, and an operator operates various devices (for example, drive columns) of the boarding bridge 20 using a joystick (not shown) of the operation panel 30. it can.

The auxiliary staircase 23 is installed on the side of the tunnel portion 25 so as to communicate the inside of the tunnel portion 25 with the ground (apron). The auxiliary staircase 23 is used for an operator to enter and exit the cab 26, for example.

The tunnel section 25 corresponds to a box-shaped passage member that forms a passenger passage between the terminal building 10 and the boarding / alighting section 11A of the aircraft 11. As shown in FIG. 2, the tunnel portion 25 includes a pair of (adjacent) first and

second tunnels

25A and 25B that overlap in a nested manner, and a pair of (adjacent) second and second that overlap in a nested manner. Three

tunnels

25B and 25C are provided. In other words, the first tunnel 25A, the second tunnel 25B, and the third tunnel 25C are respectively the same box (cuboid) and have different cross-sectional sizes, and are configured to be incorporated into a telescope in order. Yes.

The above tunnel portion 25 includes a known slide structure (not shown), whereby the tunnel portion 25 maintains the lap state between the first, second and

third tunnels

25A, 25B and 25C. By being relatively slid along the longitudinal direction (front-rear direction), it can be expanded and contracted.

Further, a known drive column (not shown) is connected to an appropriate position of the tunnel portion 25 (specifically, a portion on the front end side of the tunnel portion 25) so as to sandwich the tunnel portion 25. Therefore, when the drive wheel at the lower end of the drive column travels on the apron, the power of the telescopic movement (slide operation) in the front-rear direction is transmitted to the tunnel portion 25. Further, such a drive column is configured to be extendable in the vertical direction. Then, the tunnel portion 25 and the cab 26 can swing in the vertical direction with the rotander 24 as the base end by the expansion and contraction motion of the drive column.

Next, the configuration of the cab 26 of the boarding bridge 20 that is a characteristic part of the present embodiment will be described in detail with reference to the drawings.

FIG. 3 is a diagram schematically showing a configuration example of a cab used in the boarding bridge according to the embodiment of the present invention.

As shown in FIG. 3, the cab 26 and the passage of the tunnel portion 25 form a walking passage 31 in which a passenger can move along the traveling direction 200 between the terminal 10 and the aircraft 11.

The walking passage 31 includes a fixed passage 32 that is integral with the passage of the tunnel portion 25 and an adjustment passage 33 that is used for connection adjustment with the boarding / alighting portion 11A of the aircraft 11.

As described above, the vertical shaft 26A is provided substantially at the center in the width direction 300 of the fixed passage 32, whereby the front end portion of the cab 26 is moved to the left and right as the fixed passage 32 turns around the vertical shaft 26A. Swing exercise.

The adjustment passage 33 includes a width direction inclined floor 34 (hereinafter abbreviated as “inclined floor 34”), a connection floor 39, an elevating deck 35, and a driven slope 36.

As shown in FIG. 3, a substantially rectangular opening 34 A having a long side in the passage direction 200 is provided in a portion on the right side of the inclined floor 34, and when the inclined floor 34 is viewed in plan in the vertical direction, The elevating deck 35 and the driven slope 36 are disposed in the plane of the inclined floor 34 (that is, in the plane of the walking passage 31) so as to cover substantially the entire area of the opening 34A.

In the boarding bridge 20 of the present embodiment, since various structures can access the back surface of the lifting deck 35 from below through the opening 34A, the lifting driving force and the sliding driving force to the lifting deck 35 are lifted and lowered. Although it can be easily given to the deck 35, details thereof will be described later.
<Structure and tilting mechanism of tilted floor 34>
First, the structure of the inclined floor 34 and the inclination mechanism of the inclined floor 34 will be described in detail.

As shown in FIG. 3, the connection floor 39 having a substantially right triangle is connected to the fixed passage 32 via the first connection hinge 37 and is also connected to the inclined floor 34 via the second connection hinge 38. For this reason, the inclined floor 34 is also connected (connected) to the fixed passage 32 using the connecting floor 39.

The second connecting hinge 38 extends linearly from the vicinity of the spherical plain bearing 42 (rod end 42; details will be described later) to the right end of the cab 26 in a direction substantially perpendicular to the passing direction 200 (width direction 300). The first connecting hinge 37 extends linearly from the vicinity of the rod end 42 to the right end of the cab 26 in a direction that forms a predetermined acute angle θ with respect to the traveling direction 200. That is, the region sandwiched between the first connection hinge 37 and the second connection hinge 38 is the connection floor 39.

Further, as shown in FIG. 3, the screw shaft of the first electric cylinder 43 (screw cylinder) is fixed to the right end portion of the inclined floor 34. Thereby, the right end of the inclined floor 34 can be moved up and down by the stroke of the screw shaft of the first electric cylinder 43 extending and contracting in the vertical direction.

FIG. 4 is a diagram showing an example of the configuration of the adjustment passage and its peripheral structure as viewed in the direction of the line IV-IV in FIG. FIG. 5 is a diagram showing a configuration example of the spherical plain bearing of FIG.

As shown in FIG. 4, the inclined floor 34 includes a damper 40 made of synthetic rubber, and the damper 40 is attached over the entire width direction 300 of the front end portion of the inclined floor 34. That is, the damper 40 extends in a direction parallel to the second connecting hinge 38.

As described above, the damper 40 has a function of reducing the impact when the boarding bridge 20 contacts the aircraft 11 and maintaining the distance between the front end portion of the adjustment passage 33 and the boarding / alighting portion 11A of the aircraft 11.

Further, as shown in FIG. 4, a support roller 41 (cam follower 41) is attached to the housing 40A of the damper 40, and a roller holder 41A for pressing the head of the cam follower 41 from above and below is fixed to the fixed passage 32 via a connecting member (not shown). It is connected to. Thereby, the inclined floor 34 can slide parallel to the main surface of the inclined floor 34 with respect to the fixed passage 32 using the cam follower 41.

On the other hand, as shown in FIG. 5, the housing of the rod end 42 is fixed to the frame 32A of the fixed passage 32, and the rod 42B passing through the ball 42A of the rod end 42 is connected to the inclined floor 34 via a plate material (not shown). Has been. As a result, the rod 42B can face various angles by the spherical slip of the ball 42A, so that the inclined floor 34 can swing freely with respect to the fixed passage 32 using the rod end 42.

With the above configuration, when the right end portion of the inclined floor 34 moves up and down by the driving force of the first electric cylinder 43, the front end portion of the inclined floor 34 swings around the first connection hinge 37 and the second connection It swings around the hinge 38 as well. As a result, the inclined floor 34 can be inclined in the width direction 300. That is, the inclined floor 34 can perform a seesaw motion around a virtual straight line 400 connecting the cam follower 41 and the rod end 42.

At this time, the linear line 400 is translated by the sliding motion of the cam follower 41 in the surface of the inclined floor 34 and the free swinging motion of the rod end 42, and the connecting floor 39 swings up and down. Therefore, in the boarding bridge 20 of the present embodiment, the seesaw motion of the inclined floor 34 can be performed smoothly.

As described above, when the edge of the inclined floor 34 (that is, the edge of the floor of the elevator deck 35 to be described later) and the edge of the floor 11B of the passenger board 11A of the aircraft 11 are not parallel, the inclined floor 34 is It can be used to make parallel between the two. For example, the height of the boarding / alighting portion 11 A of the aircraft 11 varies depending on the size of the aircraft 11. In order to cope with such a change in height, the tunnel portion 25 may be inclined with different vertical heights in the front and rear. In this state, when the fixed passage 32 turns around the vertical axis 26A, the adjustment passage 33 simultaneously swings to the left and right, so that the floor edge of the lifting deck 35 and the edge of the floor portion 11B of the boarding / alighting portion 11A of the aircraft 11 And may not be parallel. In such a case, the seesaw motion of the inclined floor 34 functions effectively.

Next, an example of the elevating deck 35, the driven slope 36, and its peripheral structure will be described.

FIG. 6 is a diagram showing an example of the configuration of the adjustment passage and its peripheral structure as viewed from the line VI-VI in FIG. FIG. 7 is a diagram showing a configuration example of the peripheral structure of the adjustment passage as viewed from the line VII-VII in FIG.

As shown in FIGS. 6 and 7, in the adjustment passage 33 of the boarding bridge 20 of this embodiment, in the vicinity of the opening 34 A of the inclined floor 34, the lifting mechanism that can lift and lower the lifting deck 35 and the swing that swings the driven slope 36 are swung. A moving mechanism and a slide mechanism capable of sliding in the traveling direction 200 are incorporated.
<Elevating mechanism of lifting deck 35>
Hereinafter, the lifting mechanism of the lifting deck 35 will be described in detail.

As shown in FIG. 6, the raising / lowering mechanism of the raising / lowering deck 35 has a second electric cylinder 70 (screw cylinder) and a substantially C-shape (to be precise, a shape close to a semicircle having two bent portions) in plan view. Bracket plate 60.

The tip of the screw shaft 70A of the second electric cylinder 70 is connected to one end of the bracket plate 60 via the first rotation fulcrum 61. The main body 70B of the second electric cylinder 70 is connected to the support bracket 71 via a fourth rotation fulcrum 72, and the support bracket 71 uses appropriate fixing means (such as a support member and a bolt; not shown). It is fixed to the inclined floor 34. Further, a pair of

frames

73A and 73B are connected to the bent portion 60A of the bracket plate 60 via the second rotation fulcrum 62 (see also FIG. 7). The

frames

73A and 73B are connected to appropriate fixing means (supporting member). And a bolt or the like (not shown). Further, a pair of first and second connecting

members

64A and 64B are connected to the other end of the bracket plate 60 via a third rotation fulcrum 63, and the first connecting member 64A is a pin 64C that is passed through a long hole. Is connected to the second connecting member 64B in a swingable manner.

As shown in FIG. 6 (see also FIG. 7), the elevating mechanism of the elevating deck 35 includes a pair of first and second linear guides 68A including a support frame 65, a table 66, and a rail 67 extending in the vertical direction. 68B and a connecting frame 69 extending in the left-right direction. Here, the support frame 65 is configured in a substantially rectangular annular shape including a pair of first and

second frames

65A and 65B extending in the left-right direction and a pair of third and

fourth frames

65C and 65D extending in the up-down direction. However, it is not limited to this. For example, the support frame 65 may be formed in a cross beam shape.

The second connecting member 64B is fixed to a substantially central portion in the left-right direction of the second frame 65B of the support frame 65 using an appropriate fixing means (for example, a bolt). The rails 67 of the first and second

linear guides

68A and 68B are fixed to the third and

fourth frames

65C and 65D of the support frame 65 using appropriate fixing means (for example, bolts), respectively. ing. Further, the tables 66 of the first and second

linear guides

68A and 68B are fixed at appropriate positions on the left and right of the connecting frame 69 using appropriate fixing means (such as a support member and bolts). The connecting frame 69 is fixed to the inclined floor 34 by using appropriate fixing means (such as a support member and a bolt; not shown).

The elevating deck 35 is supported by the first frame 65A of the support frame 65 via a slide mechanism (details will be described later). Details of the support structure of the elevating deck 35 will be described later.

With the above configuration, when the stroke of the screw shaft 70 A of the second electric cylinder 70 extends, the first rotation fulcrum 61 at one end of the substantially C-shaped bracket plate 60 is driven by the driving force of the second electric cylinder 70. It is pushed forward and obliquely downward (see dotted line arrow 500 in FIG. 6). Then, the entire bracket plate 60 rotates around the second rotation fulcrum 62 of the bent portion of the bracket plate 60 (see the dotted arrow 501 in FIG. 6), and thereby the third rotation of the other end of the bracket plate 60. The fulcrum 63 moves upward (see the dotted arrow 502 in FIG. 6).

As the entire bracket plate 60 rotates, the third rotation fulcrum 63 moves slightly forward. Such forward movement of the third rotation fulcrum 63 is the first connection centered on the pin 64C. This is performed by swinging the member 64A (see FIG. 8).

As described above, when the third rotation fulcrum 63 of the bracket plate 60 moves upward, the entire support frame 65 also slides upward via the first and second

linear guides

68A and 68B, so that the lifting deck 35 can be lifted. (See the two-dot chain arrow 503 in FIG. 6).

In addition, after raising the raising / lowering deck 35, the support frame 65 and the raising / lowering deck 35 can be lowered | hung by shortening the stroke of the screw shaft 70A of the 2nd electric cylinder 70, but the movement of each part of the raising / lowering mechanism in this case is It can be easily understood by taking the above description into consideration. Therefore, the description of the movement of the lifting mechanism when the lifting deck 35 is lowered is omitted here.

Thus, in the boarding bridge 20 of this embodiment, the raising / lowering deck 35 is comprised so that it may raise / lower appropriately using the raising / lowering mechanism of the raising / lowering deck 35. FIG.
<Oscillation mechanism of driven slope 36>
Next, the swing mechanism of the driven slope 36 will be described in detail.

As shown in FIGS. 3 and 6, the front end portion (fixed end portion) of the plate-like driven slope 36 swings to the rear end portion of the lifting deck 35 via the third connection hinge portion 50 (connection swing shaft). It is connected freely. Here, the 3rd connection hinge part 50 is extended in the linear form to the both ends of the raising / lowering deck 35 (following slope 36) in the direction which cross | intersects (in this case, substantially orthogonal) in the passage direction 200.

6A, the rear end portion (free end portion) of the driven slope 36 is placed on the inclined floor 34 in a free state due to the gravitational action (self-weight) of the driven slope 36. ing. Therefore, the driven slope 36 can swing relative to the lifting deck 35 around the third connecting hinge portion 50.

As described above, when the elevating deck 35 is lifted (see the two-dot chain line arrow 503 in FIG. 6), the third connecting hinge portion 50 is also lifted, whereby the angle formed by the main surface of the elevating deck 35 and the main surface of the driven slope 36 is increased. The inclination angle φ of the driven slope 36 corresponding to is continuously increased. At the same time, as shown in the partial view 6A of FIG. 6, the rear end portion of the driven slope 36 moves forward while sliding on the inclined floor 34 (see a two-dot chain line arrow 504 in the partial view 6A).

Conversely, when the elevating deck 35 is lowered after the elevating deck 35 is lifted, the third connecting hinge portion 50 is also lowered, whereby the inclination angle φ of the driven slope 36 is continuously reduced. At the same time, the rear end of the driven slope 36 moves backward while sliding on the inclined floor 34.

In this manner, in the boarding bridge 20 of the present embodiment, the inclination angle φ of the driven slope 36 changes as the lifting deck 35 moves up and down (in other words, the driven slope 36 swings relative to the lifting deck 35). ), The rear end portion of the driven slope 36 is configured to linearly move (swing) in the front-rear direction. Thereby, the driven slope 36 forms an inclined path between the elevating deck 35 and the inclined floor 34 (walking passage 31).
<Sliding mechanism of lifting deck 35>
Next, the slide mechanism of the lifting deck 35 will be described in detail.

As shown in FIGS. 6 and 7, the slide mechanism of the elevating deck 35 is supported by a third linear guide 83 including a table 80, a rail 81 extending in the front-rear direction, and the table 80 of the third linear guide 83. A pair of first and

second urging mechanisms

Each of the first and

second urging mechanisms

86A and 86B includes a cylindrical spring shaft 85 extending in the front-rear direction, a spring 84 (elastic body) fitted around the spring shaft 85, and the spring 84. And a pair of

stopper members

87 and 88 that contact the ends.

It should be noted that both ends of the spring shaft 85 are threaded and appropriate fixing means (nuts or the like) are screwed to the both ends, thereby restricting the movement of the

stopper members

87 and 88 in the front-rear direction.

The stopper member 88 on the rear end side of the spring 84 is fixed to the table 80 of the third linear guide 83 using appropriate fixing means (bolts or the like). On the other hand, the stopper member 87 at the front end portion of the spring 84 is fixed to the back surface of the elevating deck 35 using appropriate fixing means (such as a support member and a bolt).

That is, the elevating deck 35 is mounted on the table 80 via the first and

second urging mechanisms

86A and 86B, so that the elevating deck 35 (and the driven slope 36 connected to the elevating deck 35) It is configured to be slidable in the same direction by the sliding movement of 80 in the front-rear direction. The urging action of the first and

second urging mechanisms

The fourth linear guide 92A is disposed in the vicinity of the third frame 65C of the support frame 65, and the rail 91 of the fourth linear guide 92A is attached to the third frame 65C by using an appropriate fixing means (such as a frame). It is fixed. The fifth linear guide 92B is disposed in the vicinity of the fourth frame 65D of the support frame 65, and the rail 91 of the fifth linear guide 92B uses the appropriate fixing means (such as a frame) to form the fourth frame. It is fixed at 65D. Further, the elevating deck 35 is supported by the tables 90 of the fourth and fifth

linear guides

92A and 92B.

With the above configuration, the sliding movement of the elevating deck 35 in the front-rear direction is stably performed while supporting the elevating deck 35 appropriately.

Thus, in the boarding bridge 20 of the present embodiment, the elevating deck 35 can slide in the front-rear direction using the slide mechanism of the elevating deck 35, and the elevating deck 35 is attached to the support frame 65 via the slide mechanism. It is configured so that it can be supported.
<Example of connection operation of boarding bridge 20 to boarding / exiting part 11A of aircraft 11>
Next, an example of the connection operation of the boarding bridge 20 of this embodiment to the boarding / alighting part 11A of the aircraft 11 will be described.

8 and 9 are diagrams used for explaining an example of the operation of connecting the boarding bridge to the boarding / alighting section of the aircraft according to the embodiment of the present invention. FIG. 8 illustrates a state in which the elevating deck 35 is being connected to the boarding / exiting part 11A of the aircraft 11, and FIG. 9 illustrates a state when the elevating deck 35 is completely connected to the boarding / exiting part 11A of the aircraft 11. Yes.

The connection operation of the boarding bridge 20 to the boarding / exiting part 11A of the aircraft 11 according to the present embodiment is performed as follows.

First, the cab 26 (fixed passage 32) is turned around the vertical axis 26A. Then, the adjustment passage 33 simultaneously swings left and right.

Next, the drive column is moved to bring the boarding bridge 20 closer to the aircraft 11 so that the damper 40 of the boarding bridge 20 contacts the aircraft 11. At this time, when the edge of the floor of the elevating deck 35 and the edge of the floor 11B of the boarding / alighting part 11A of the aircraft 11 are not parallel to each other, the two can be paralleled by using the inclined floor 34. .

At this stage, the elevator deck 35 of the boarding bridge 20 is located below the floor of the boarding / alighting part 11A, so that the door of the boarding / alighting part 11A of the aircraft 11 can be opened.

After the door of the boarding / alighting part 11A of the aircraft 11 is opened, as shown in FIGS. 8 and 9, the elevating deck 35 is brought to the same height as the floor part 11B of the boarding / alighting part 11A of the aircraft 11 by the elevating mechanism of the elevating deck 35. While moving (raising), a synthetic rubber damper 51 is applied to the floor portion 11B of the boarding / alighting portion 11A of the aircraft 11 by the sliding mechanism of the elevating deck 35.

As shown in FIG. 3, the elevating deck 35 includes a damper 51, and the damper 51 is attached over the entire width direction 300 of the front end portion of the elevating deck 35. For this reason, it is possible to mitigate the impact when the lifting deck 35 contacts the boarding / alighting portion 11 A of the aircraft 11 using the damper 51. At this time, with the movement of the lifting deck 35, the inclination angle φ of the driven slope 36 automatically changes as the third connecting hinge portion 50 is lifted by the action of gravity of the driven slope 36 itself (self-weight). The rear end of the slope 36 moves forward so as to slide on the inclined floor 34 (see FIG. 6).

As described above, the boarding bridge 20 of the present embodiment is provided in the plane of the walking path 31 in plan view and the lifting deck 35 used for connection with the boarding / alighting part 11A of the aircraft 11 and the lifting deck. And an elevating mechanism for elevating and lowering 35, and a fixed slope portion of which is connected to the elevating deck 35 using a third connecting hinge 50, and a free end portion of which is supported on the walking path 31. As the elevating deck 35 moves, the driven slope 36 rotates around the axis of the third connecting hinge 50, so that the driven slope 36 is continuously between the elevating deck 35 and the walking passage 31 (inclined floor 34). A gentle slope.

With the above configuration, since there is no step between the floor portion 11B of the boarding / alighting portion 11A and the lifting deck 35 of the boarding bridge, a continuous passage can be formed between the two.

Therefore, in the boarding bridge 20 of the present embodiment, a step with the boarding / alighting part 11A of the aircraft 11 can be eliminated, and for example, each time a passenger on a wheelchair gets on and off the aircraft 11, the lifting deck 35 is raised and lowered. Since there is no need, passengers can get on and off smoothly between the terminal 10 and the aircraft 11.

In particular, in the boarding bridge 20 of the present embodiment, the height of the lifting deck 35 can be adjusted by a simple lifting movement of the lifting deck 35, so that the floor of the lifting deck 35 is maintained substantially horizontal without being inclined. can do. For this reason, there exists an advantage that alignment with the raising / lowering deck 35 and the floor part 11B of the boarding / alighting part 11A is easy.

Further, in the boarding bridge 20 of the present embodiment, the elevating deck 35 includes a slide mechanism that slides in the direction of human traffic. And the raising / lowering deck 35 moves to the same height as the floor part 11B of the boarding / alighting part 11A by the raising / lowering mechanism, and contacts the boarding / alighting part 11A by the slide mechanism.

With the above configuration, even if a slight gap is generated between the lifting deck 35 and the boarding / alighting part 11A of the aircraft 11, the sliding mechanism can slide to the position where the lifting deck 35 contacts the boarding / alighting part 11A. Such a gap can also be eliminated.

In the boarding bridge 20 of the present embodiment, the walking path 31 includes an inclined floor 34 that adjusts the inclination of the elevating deck 35 and the driven slope 36 in the width direction, an inclination mechanism that can incline the inclined floor 34 in the width direction 300, and When the inclined floor 34 is viewed in plan, the elevating deck 35 and the driven slope 36 are attached in the plane of the inclined floor 34.

As described above, when the edge of the floor of the elevating deck 35 and the edge of the floor 11B of the boarding / alighting part 11A of the aircraft 11 are not parallel, the two can be parallelized using the inclined floor 34. it can. In particular, in the boarding bridge 20 of the present embodiment, the parallel adjustment between the elevating deck 35 and the getting-on / off part 11A by the inclined floor 34 can be performed even while the drive column of the boarding bridge 20 is being moved. Can be connected efficiently.

Further, in the boarding bridge 20 of the present embodiment, the first and

second urging mechanisms

86A and 86B of the slide mechanism are used to further lift and lower from the position where the damper 51 of the lifting deck 35 abuts on the getting-on / off portion 11A. When the table 80 is slid so as to press the deck 35 against the boarding / alighting portion 11A, an urging force of the elevating deck 35 (damper 51) to the aircraft 11 is generated. That is, when the table 80 is slid so as to press the elevating deck 35 against the loading / unloading portion 11A from the contact position, the stopper member 88 resists the reaction force of the spring 84 as shown in FIGS. Move forward along axis 85. Then, the spring 84 is compressed by the

stopper members

87 and 88, and the urging force of the elevating deck 35 (damper 51) to the aircraft 11 is generated based on the reaction force of the spring 84 generated thereby.

With the above configuration, in the boarding bridge 20 of the present embodiment, the gap between the lifting deck 35 (damper 51) and the boarding / alighting part 11A (outer wall) of the aircraft 11 varies due to the ups and downs of the aircraft 11 as passengers get on and off. Even so, the first and

second urging mechanisms

86A and 86B of the slide mechanism can move the lifting deck 35 (damper 51) in the front-rear direction in accordance with the ups and downs of the aircraft 11, Generation | occurrence | production of the said clearance gap can be prevented appropriately.

From the above description, many modifications and other embodiments of the present invention are apparent to persons skilled in the art. Accordingly, the foregoing description is to be construed as illustrative only and is provided for the purpose of teaching those skilled in the art the preferred mode of carrying out the invention. The details of the structure and / or function may be substantially changed without departing from the spirit of the invention.

Therefore, first, second, and third modifications of the embodiment of the present invention are illustrated below.
(First modification)
In the boarding bridge 20 of the present embodiment, as shown in FIG. 3, the second connecting hinge 38 extends linearly to the right end of the cab 26 in a direction (width direction 300) substantially orthogonal to the passing direction 200. The extending direction of the second connecting hinge 38 does not necessarily need to be orthogonal to the passing direction 200.

For example, as shown in the cab 126 of FIG. 10, even if the right end portion of the second connection hinge 138 is moved forward (even if the extending direction of the second connection hinge 138 is not orthogonal to the passage direction 200), The inclined floor 34 can be appropriately inclined in the width direction 300.

However, as in the boarding bridge 20 (FIG. 3) of the present embodiment, if the extending direction of the second connecting hinge 38 is orthogonal to the traveling direction 200, the rear end portion of the driven slope 36 can be sufficiently moved rearward. There is an advantage that the slope of the driven slope 36 can be reduced when the elevating deck 35 and the boarding / alighting portion 11A of the aircraft 11 are connected.
(Second modification)
The boarding bridge 20 of the present embodiment includes an inclined floor 34 that adjusts the inclination of the elevating deck 35 and the driven slope 36 in the width direction 300, but parallel adjustment between the elevating deck 35 and the boarding / alighting portion 11A is not limited thereto. Other methods can be used.

For example, as shown in FIG. 11, the elevating deck 135 may include a structure in which the damper 151 and the floor board 101 are connected via the rotating shaft 100. The rear end portion of the floor board 101 is connected to the driven slope 136 using the third connecting hinge 150. Moreover, the rotating shaft 100 of this damper 151 is connected to the side edge part of the floor board 101, as shown in FIG.

Furthermore, in the lifting deck 135, a rubber plate 400 (elastic plate) is disposed on the damper 151 and the floor plate 101 so as to straddle between the damper 151 and the floor plate 101 and cover almost the entire area of the floor plate 101. And fastening area | region 401A is provided over the width direction 300 of the front-end part of the rubber plate 400, and is being fixed to the damper 151 using the appropriate fastening member and adhesive agent. Further, a fastening region 401B is provided across the width direction 300 of the rear end portion of the rubber plate 400, and is fixed to the floor plate 101 using an appropriate fastening member or adhesive.

With the above configuration, when the damper 151 rotates upward about the rotation shaft 100 based on the driving force of a driving device (not shown) such as a motor, the elastic plate 400 causes the elastic plate 400 to move from the rear end to the front end. The rubber plate 400 can be tilted moderately in the width direction 300 as it goes to the side, and as a result, the parallel shift between the elevating deck 35 and the boarding / alighting portion 11A can be easily absorbed.
(Third Modification)
The boarding bridge 20 of the present embodiment is configured such that both the elevating deck 35 and the driven slope 36 slide in the passage direction 200, but the present invention is not limited to this, and other methods can be used.

For example, as shown in FIG. 12, the lifting deck 235 includes a floor plate 201 connected to the driven slope 236 using the third connecting hinge 250, a slide floor 110 that is supported by the floor plate 201 and slides in the passage direction 200, A damper 111 at the front end of the slide floor 110 may be provided.

Thereby, using a slide device (not shown) such as a linear guide, the slide floor 110 (damper 111) can be slid only in the passing direction 200 so that the slide floor 110 abuts on the getting-on / off portion 11A. Therefore, since it is not necessary to slide the driven slope 236 largely according to the sliding operation of the slide floor 110, the structure in which the free end portion of the driven slope 236 is supported by the inclined floor 34 and the sliding structure can be simplified.

Further, instead of the slide floor 110, a rotatable plate may be provided on the floor plate 201. Specifically, a rotating plate having one end connected using a connecting swing shaft such as a hinge extending in the width direction 300 is provided on the upper front side of the floor plate 201. And when the raising / lowering deck 235 is not connected with the boarding / alighting part 11A, the rotating plate is folded and overlapped on the floor board 201, and when the raising / lowering deck 235 is connected with the boarding / alighting part 11A, the other end side of the rotating plate is the boarding / alighting part 11A. Unfold to reach the floor 11B.

Thus, even if there is no slide floor or slide mechanism, it is possible to easily eliminate the gap between the lifting deck 235 and the boarding / exiting portion 11A.

According to the boarding bridge of the present invention, it is possible to eliminate the level difference between the moving body and the boarding / exiting section, and passengers can get on and off smoothly between the terminal and the moving body. Therefore, this invention can be utilized as an air passenger boarding bridge, for example.
