Description

Passenger boarding bridge

The present invention relates to a passenger boarding bridge.

A passenger boarding bridge is known as a facility used for passengers getting on and off between an airport terminal building and an aircraft. When the cab of the passenger boarding bridge is connected to the boarding / alighting section of the aircraft, a walking path for passengers to the aircraft is formed using the passenger boarding bridge.

Here, there is a case where the lower end of the door of the boarding / alighting part of the aircraft moves below the floor part (door sill) of the boarding / alighting part of the aircraft when the door is opened and closed. For this reason, when the position of the cab walk path is set so that there is no step between the door sill of the boarding area and the cab walk path of the passenger boarding bridge, the lower end of the door is connected to the cab when opening and closing the door of the boarding area. Hit the walkway. Therefore, the door cannot be opened and closed.

From the above, it is necessary to make the position of the walking path of the cab lower by, for example, about 200 mm at the maximum than the position of the door sill in the getting-on / off section. However, in this case, the step between the door sill of the boarding / exiting portion and the walking path of the cab 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, conventionally, in order to eliminate the inconvenience due to the above steps, a part of the walking path of the cab is configured as a movable floor, and a step eliminating device that tilts or lifts (moves up and down) the movable floor (for example, Patent Documents). 1-4) has already been proposed.

Moreover, the passenger boarding bridge of the 1st and 2nd aspect of this invention is not limited to the following specific description.
[Overall configuration of the device]
FIG. 1 is a diagram illustrating an example of a passenger boarding bridge according to an embodiment of the present invention. Here, a state in which the entire length of the tunnel portion 10 is extended is shown.

Hereinafter, for the sake of convenience, the direction in which the entire length of the tunnel portion 10 of the passenger boarding bridge 100 expands and contracts is defined as the front-rear direction, the direction in which gravity acts on the passenger boarding bridge 100 is defined as the vertical direction, and the width direction of the passenger boarding bridge 100 A direction orthogonal to the direction) will be described as the left-right direction. Further, as shown in FIG. 1, in the passenger boarding bridge 100, the aircraft 200 side is described as “front”, and the terminal building (not shown) side is described as “rear”.

A passenger boarding bridge 100 according to the present embodiment is arranged at a rotunda (rear circular chamber) 12 connected to an entrance / exit of a terminal building, a tunnel part 10 connected to the rotander 12, and an end part in front of the tunnel part 10. A cab (front circular chamber) 20.

The tunnel portion 10 is configured such that

adjacent tunnels

10A and 10B are nested in a relative relationship between the outside and the inside, and the entire length of the tunnel portion 10 is configured to be extendable in the front-rear direction. Specifically, the drive column 15 is coupled to an appropriate position of the tunnel portion 10 (specifically, a portion in front of the outer tunnel 10B) so as to sandwich the tunnel portion 10 therebetween. Therefore, when the driving wheel at the lower end of the drive column 15 travels on the ground 18 (apron 18), the power of the telescopic movement in the front-rear direction is transmitted to the tunnel portion 10. When the cab 20 arranged at the front end of the tunnel unit 10 reaches the boarding / unloading unit 202 (see FIG. 2 and the like) of the aircraft 200 by extending the entire length of the tunnel unit 10, A walking path for passengers between 200 passengers 202 is formed. At this time, the tunnel part 10 can be moved up and down with reference to the rotander 12 by the vertical movement of the drive column 15.

An operation panel 50 (see FIG. 2 and the like) is disposed in the cab 20, and an operator uses the joystick (not shown) of the operation panel 50 to each device (for example, drive column) of the passenger boarding bridge 100. 15 etc.). The auxiliary staircase 16 is provided on the side of the tunnel portion 10 so as to connect the inside of the tunnel portion 10 and the apron 18. The auxiliary staircase 16 is used, for example, for an operator to enter and exit the cab 20.
[Composition of cab]
Hereinafter, the configuration of the cab of this embodiment will be described with reference to the drawings.

2 and 3 are diagrams showing an example of a passenger boarding bridge cab according to an embodiment of the present invention.

2, the cab 20 includes a walking passage 21, a closure 28, and a step difference eliminating device 30.

The walking passage 21 includes a fixed floor (not shown) connected at the tip of the tunnel portion 10 and an inclined floor 21A connected to the fixed floor and configured to be tiltable in the width direction 300. Note that such a tilting mechanism of the tilted floor 21A may be the same as the tilting mechanism described in Patent Document 3-4. Therefore, here, the detailed description of this mechanism is not given, but it outlines below.

For example, the fixed floor and the inclined floor 21A are connected to each other through a connecting hinge portion or the like (not shown). Then, the right end or left end of the inclined floor 21A moves up and down by the power of a power generator (not shown) such as a power cylinder or an electric motor. Then, the front end portion of the inclined floor 21A can swing around the connecting hinge portion. Thereby, the inclined floor 21 A can be inclined in the width direction 300. A synthetic rubber bumper 21B is disposed at the front end of the inclined floor 21A. The bumper 21 B has a function of mitigating impact when the inclined floor 21 A contacts the boarding / alighting part 202 of the aircraft 200, and a function of maintaining a distance between the front end of the inclined floor 21 A and the boarding / alighting part 202 of the aircraft 200.

The closure 28 includes a bellows part (not shown) that can be expanded and contracted in the front-rear direction, and a portal-type contact body (not shown) that is provided at the front end of the bellows part and comes into contact with the aircraft 200. Thereby, when the passenger boarding bridge 100 is mounted on the aircraft 200, the contact body can be brought into contact with the periphery of the boarding / unloading portion 202 of the aircraft 200 by tilting forward.

The level difference eliminating device 30 includes an elevating floor 31, a driven slope 32, and a door sill detector 39. In the present embodiment, the elevating floor 31 is an example of a movable floor that is used for connection with a door sill 202A (details will be described later) of the boarding / alighting unit 202 of the aircraft 200 and configured to be movable up and down.

Here, as shown in FIG. 2, a substantially rectangular opening 29 having a long side in the passenger's passage direction 301 (front-rear direction) is provided in a portion on the left side of the inclined floor 21A. In addition, when the inclined floor 21A is viewed in a plan view in the vertical direction, the rectangular lift floor 31 and the follower slope 32 are within the plane of the inclined floor 21A (that is, the walking passage 21) so as to cover substantially the entire area of the opening 29. In-plane).

And in the level | step difference elimination apparatus 30 of this embodiment, since various structures can access the back surface of the raising / lowering floor 31 from the downward direction through the opening part 29, the motive power for the raising / lowering movement (up-down movement) of the raising / lowering floor 31 is possible. And the power for the horizontal movement of the raising / lowering floor 31 can be easily given to the raising / lowering floor 31.

That is, in the level difference elimination device 30 of the present embodiment, in the vicinity of the opening 29 of the elevator floor 31, an elevator mechanism that can move the elevator floor 31 up and down, and a horizontal movement mechanism that can move horizontally in the passage direction 301 through the elevator floor 31. Is provided.

<Elevating mechanism of elevating floor 31>
As shown in FIG. 3, the lifting mechanism of the lifting floor 31 includes a support frame 33, a linear guide 34, a connecting frame 37, and a power generator 35.

In the present embodiment, the support frame 33 is configured in a substantially rectangular ring shape including a pair of frames extending in the left-right direction and a pair of frames extending in the up-down direction, but is not limited thereto. For example, the shape of the support frame 33 may be a cross beam shape.

The linear guide 34 includes a table 34A and a rail 34B extending in the vertical direction.

Note that the rail 34B of the linear guide 34 is fixed to the support frame 33 by using appropriate fixing means (for example, bolts). Further, the connecting frame 37 is fixed to the inclined floor 21A by using appropriate fixing means (such as a support member and a bolt; not shown).

The elevating floor 31 is supported by the support frame 33 via a horizontal movement mechanism (details will be described later) of the elevating floor 31, and the support structure of the elevating floor 31 will be described later.

The power generator 35 generates power for moving the lifting floor 31 up and down. The power generator 35 may have any configuration as long as it can generate power for moving the lifting floor 31 up and down. For example, the specific configuration of such a power generator 35 may be the same as the configuration described in Patent Document 3-4. Therefore, detailed description of this configuration is omitted here. Examples of the driver of the power generator 35 include a power cylinder or an electric motor.

As described above, when the support frame 33 slides in the vertical direction with respect to the connection frame 37 via the linear guide 34 by the power of the power generator 35, the lift floor 31 can be moved up and down.

At this time, as shown in FIGS. 2 and 3, the front end portion (fixed end portion) of the plate-like driven slope 32 is connected to the rear end portion of the lift floor 31 via the connection hinge portion 38 (connection swing shaft). It is swingably connected. As shown in FIG. 3, the rear end portion (free end portion) of the driven slope 32 is placed on the inclined floor 21 A in a free state due to the gravity (self-weight) of the driven slope 32. Therefore, the driven slope 32 can swing relative to the lift floor 31 around the connecting hinge portion 38.

As described above, when the elevating floor 31 moves upward, the connecting hinge portion 38 also moves upward, whereby the inclination of the driven slope 32 corresponding to the angle formed by the main surface of the elevating floor 31 and the main surface of the driven slope 32. The angle θ increases continuously. At the same time, the rear end portion of the driven slope 32 moves forward on the inclined floor 21A. On the other hand, when the elevating floor 31 moves downward, the connecting hinge portion 38 also moves downward, whereby the inclination angle θ of the driven slope 32 continuously decreases. At the same time, the rear end of the driven slope 32 moves rearward on the inclined floor 21A.

In this manner, in the passenger boarding bridge 100 of the present embodiment, the inclination angle θ of the driven slope 32 is changed by the up-and-down movement of the lifting floor 31 (that is, the driven slope 32 swings relative to the lifting floor 31). However, the rear end portion of the driven slope 32 is configured to linearly move in the passing direction 301 on the inclined floor 21A. Thereby, the follower slope 32 forms an inclined path between the elevating floor 31 and the inclined floor 21A (walking passage 21).

<Horizontal moving mechanism of lifting floor 31>
As shown in FIG. 3, the horizontal movement mechanism of the lifting floor 31 includes a linear guide 44, an urging mechanism 41, and a power generator 45.

The linear guide 44 includes a table 44A and a rail 44B extending in the passage direction 301 (front-rear direction). The rail 44 B of the linear guide 44 is fixed to the support frame 33 using appropriate fixing means (a support member, bolts, etc .; not shown).

The urging mechanism 41 includes a columnar spring shaft 42 extending in the passage direction 301, a spring 42A (elastic body) fitted around the spring shaft 42, and a pair of stoppers that contact the ends of the spring 42A.

Members

43A and 43B. Both ends of the spring shaft 42 are threaded, and appropriate fixing means (such as nuts) are screwed to the both ends, thereby restricting movement of the

stopper members

43A and 43B in the passage direction 301. . The stopper member 43B on the rear end side is fixed to the table 44A of the linear guide 44 using appropriate fixing means (bolts or the like). On the other hand, the stopper member 43A at the front end is fixed to the back surface of the elevating floor 31 using appropriate fixing means (such as a support member and a bolt). That is, the elevating floor 31 is mounted on the table 44 A of the linear guide 44 via the biasing mechanism 41. Thereby, the elevating floor 31 (and the follower slope 32 connected to the elevating floor 31) can move horizontally in the same direction by sliding in the passage direction 301 of the table 44A of the linear guide 44. A synthetic rubber bumper 31 B is disposed at the front end portion of the lift floor 31. The bumper 31 B has a function of mitigating an impact when the lifting floor 31 comes into contact with the landing section 202 of the aircraft 200, and a function of maintaining a distance between the front end portion of the lifting floor 31 and the landing section 202 of the aircraft 200.

The power generator 45 generates power for horizontal movement of the elevating floor 31. The power generator 45 may have any configuration as long as it can generate power for horizontal movement of the elevating floor 31. For example, the specific configuration of such a power generator 45 may be the same as the configuration described in Patent Document 3-4. Therefore, detailed description of this configuration is omitted here. Examples of the driver of the power generator 45 include a power cylinder or an electric motor.

As described above, in the passenger boarding bridge 100 of the present embodiment, the elevating floor 31 can be horizontally moved using the horizontal moving mechanism of the elevating floor 31 and can be supported by the support frame 33 via the horizontal moving mechanism.

At this time, as shown in FIG. 7, the bumper 31 B of the lift floor 31 is further moved from the position where the bumper 31 B of the lift floor 31 abuts on the landing unit 202 of the aircraft 200 using the biasing mechanism 41 of the horizontal movement mechanism. The table 44 A of the linear guide 44 is moved horizontally so as to be pressed against the getting-on / off unit 202. Thereby, the urging | biasing force to the aircraft 200 of the raising / lowering floor 31 (bumper 31B) arises. That is, when the table 44A is horizontally moved forward so as to press the elevating floor 31 against the boarding / lowering portion 202 from the contact position, the stopper member 43B moves forward along the spring shaft 42 against the reaction force of the spring 42A. Move to. Then, the spring 42A is compressed by the

stopper members

43A and 43B, and the urging force of the elevating floor 31 (bumper 31B) to the aircraft 200 is generated based on the reaction force of the spring 42A generated thereby.

As described above, in the passenger boarding bridge 100 of the present embodiment, when the distance between the elevator floor 31 (bumper 31B) and the boarding / alighting part 202 (outer wall) of the aircraft 200 varies due to the ups and downs of the aircraft 200 as passengers get on and off. Even if it exists, by the effect | action of the urging | biasing mechanism 41 of said horizontal movement mechanism, according to the ups and downs of the aircraft 200, the raising / lowering floor 31 (bumper 31B) can be moved following the moving direction 301 (front-back direction). Therefore, it is possible to appropriately prevent a gap between the elevating floor 31 (bumper 31B) and the getting-on / off unit 202 of the aircraft 200.

[Control system configuration]
Next, the structure of the control system of the passenger boarding bridge 100 of this embodiment is demonstrated.

2 and 3, the door sill detector 39 of the step eliminating device 30 is provided on the lift floor 31. In the present embodiment, the door sill detector 39 is fixed to the front end of the lift floor 31 and in the vicinity of the left end. The door sill detector 39 detects the door sill 202 A of the boarding / alighting unit 202 of the aircraft 200. Specifically, the door sill detector 39 outputs a detection signal when the tip of the lift floor 31 reaches the same plane as the door sill 202A of the boarding / alighting section 202 of the aircraft 200 while the lift floor 31 is moving up and down. The door sill detector 39 may have any configuration as long as the door sill 202A of the boarding / alighting unit 202 of the aircraft 200 can be detected. As the door sill detector 39, for example, a photodetector such as an infrared sensor can be exemplified. That is, when the door sill detector 39 is an infrared sensor, the door sill 202A of the getting-on / off unit 202 can be detected by the amount of change in infrared energy due to reflection and transmission of infrared light from the door sill detector 39A.

When the door sill detector 39 outputs a detection signal while the elevator floor 31 is moved up and down by the power of the power generator 35, the controller 50 A of the operation panel 50 controls the power generator 35 to stop the movement of the elevator floor 31. Control the behavior.

As described above, in the passenger boarding bridge 100 of the present embodiment, by providing the door sill detector 39 on the elevator floor 31, it is possible to appropriately perform automatic control of the elevation movement of the elevator floor 31. That is, when the tip of the lift floor 31 moves on the same plane as the door sill 202A of the getting on / off portion 202 so that there is no step between the door sill 202A of the getting on / off portion 202 and the lift floor 31 of the cab 20, the lift floor The up-and-down movement of 31 can be stopped appropriately.

The controller 50A may have any configuration as long as it has a control function. The controller 50A may include, for example, a calculation unit (not shown) and a storage unit (not shown) that stores a control program. As a calculating part, PLC, MPU, CPU etc. can be illustrated, for example. An example of the storage unit is a memory. The controller 50A may be composed of a single controller or a plurality of controllers.

[Operation]
4 and 5 are flowcharts showing an example of the operation of the passenger boarding bridge of the present embodiment. The following automatic control operation of the passenger boarding bridge 100 is performed by the control program of the controller 50A.

Here, Step S1 to Step S7 in FIG. 4 may be the same as the operation of the auto-docking function described in JP-A-2002-37196. Therefore, step S1 to step S7 are outlined here without detailed description.

FIG. 4 shows the operation until the passenger boarding bridge 100 moves from the parking position to the mounting position on the aircraft 200.

First, in step S1, the operator selects a model of the aircraft 200 by pressing a model selection button on an operation panel (not shown) of the operation panel 50. Based on this model selection, a predetermined mounting position corresponding to the model is determined from a plurality of preset mounting positions.

Next, when the operator presses the start button on the operation panel, the following automatic control starts. In the present embodiment, the start button is configured as a button that is turned on only when the operator is pressing the button, that is, a deadman switch button. Therefore, when the operator releases the button, the following automatic control is forcibly stopped.

In step S2, various control amounts up to the mounting position (for example, the rotation angle of the cab 20, etc.) based on the model selection and detection results of an appropriate angle sensor (not shown) and position sensor (not shown). The vertical movement amount of the tunnel portion 10, the rotation angle of the drive wheel of the drive column 15, and the travel distance) are calculated.

Next, based on the calculation result, in step S4, the cab 20 is rotated, and in step S5, the tunnel unit 10 is moved up and down.

At the same time, in step S3 and step S6, the drive wheels of the drive column 15 are controlled. Specifically, in step S3, the driving wheel rotates in the direction of the mounting position (target position), and then, in step S6, the driving wheel travels on the apron 18 in this direction.

In step S7, a distance between the bumper 21B of the inclined floor 21A of the cab 20 and the aircraft 200 is determined based on a detection result of a photoelectric distance sensor (not shown) (for example, 1 m). It is determined whether or not.

If the determination result in step S7 is No, the above operation is performed as it is. On the other hand, if Yes, the process proceeds to step S8.

In step S8, the inclination angle automatic control in the width direction 300 of the inclined floor 21A of the cab 20 is performed based on the output signal of the angle adjustment detector (not shown) of the inclination angle in the width direction 300. Specifically, the power generator is controlled so that the inclination angle of the inclined floor 21A becomes a predetermined target value based on the output signal of the angle adjustment detector. For example, the power generator is controlled so that the inclined floor 21 A is parallel to the apron 18. As a result, the controller 50A determines the width of the inclined floor 21A based on the output signal of the angle adjustment detector when the inclined floor 21A of the cab 20 and the door sill 202A of the getting-on / off unit 202 of the aircraft 200 are not parallel. The tilt angle in direction 300 is automatically controlled.

Thereafter, the cab 20 is attached to the boarding / alighting section 202 of the aircraft 200 by manual operation of the operator, and the mounting of the cab 20 of the passenger boarding bridge 100 to the aircraft 200 is completed.

Also, the passenger boarding bridge 100 is set to the auto level mode by the manual operation of the operator using the key switch (not shown) of the operation panel 50. Thereby, for example, when the body of the aircraft 200 moves up and down due to passengers getting on and off, the vertical extension mechanism of the drive column 15 is controlled so that the cab 20 follows the vertical movement.

Here, as shown in FIG. 6, when the cab 20 is mounted on the landing part 202 of the aircraft 200, the walking path 21 (inclined floor 21 A) of the cab 20 connected to the tip of the tunnel part 10 (see FIG. 1) is The aircraft 200 is located below the boarding / alighting portion 202 of the aircraft 200. This is due to the following reason.

The lower end portion of the door 201 of the boarding / alighting unit 202 may move below the door sill 202A of the boarding / alighting unit 202 of the aircraft 200 when the door 201 is opened and closed. For this reason, when the position of the walking path 21 (inclined floor 21A) of the cab 20 is set so that the door sill 202A of the getting-on / off section 202 and the walking path 21 (inclined floor 21A) of the cab 20 do not have a step G, the door 201 cannot be opened or closed. That is, the door 201 hits the walking passage 21 (inclined floor 21A) of the cab 20 when the door 201 of the boarding / alighting portion 202 is opened and closed.

Therefore, as shown in FIG. 6, when the cab 20 is mounted on the boarding / alighting part 202 of the aircraft 200, the walking path 21 (inclined floor 21 A) is arranged below the boarding / alighting part 202 of the aircraft 200, thereby Is properly opened and closed. Then, after the door 201 is opened by the operator's manual operation, the operation proceeds to the operation shown in FIG.

5, the level difference G between the door sill 202A of the boarding / alighting part 202 and the lifting floor 31 of the cab 20 is eliminated by the level difference eliminating device 30, and then the lifting floor 31 is attached to the door sill 202A of the boarding / lowering part 202. The operation up to is described.

First, in step S 9, the cab 20 is moved upward of the lift floor 31 by the power of the power generator 35.

In step S10, based on the detection result of the door sill detector 39, it is determined whether or not the door sill 202A of the boarding / alighting unit 202 has been detected. That is, as shown in FIG. 3, the detection signal is output from the door sill detector 39 when the tip of the lift floor 31 of the cab 20 reaches the same plane as the door sill 202 A of the boarding / alighting unit 202. Thereby, it is determined that the door sill 202A of the boarding / alighting unit 202 is detected by the detection signal of the door sill detector 39.

When the determination result in step S10 is No, the above-described moving operation of the elevator floor 31 is performed as it is. On the other hand, in the case of Yes, it progresses to step S11 and the movement to the upper direction of the raising / lowering floor 31 by the motive power of the motive power generator 35 stops.

Next, in step S12, the cab 20 is moved horizontally to the front of the lift floor 31 by the power of the power generator 45.

In step S13, based on the detection result of a limit switch (not shown), it is determined whether or not the contact between the bumper 31B of the elevator floor 31 and the door sill 202A of the getting-on / off unit 202 is detected. For example, such a limit switch may be arranged in the urging mechanism 41. In this case, as shown in FIG. 7, after the contact between the bumper 31B and the door sill 202A, the limit switch is moved forward by a predetermined amount along the spring shaft 42 against the reaction force of the spring 42A. It can be a switch that turns on when it moves. Thereby, the pressing force of the contact between the bumper 31B and the door sill 202A can be set easily and appropriately.

If the determination result in step S13 is No, the above-described lifting floor 31 is moved horizontally in the forward direction. On the other hand, in the case of Yes, it progresses to step S14 and the horizontal movement ahead of the raising / lowering floor 31 of the cab 20 by the motive power of the motive power generator 45 stops.

Thus, in the passenger boarding bridge 100 of the present embodiment, automatic control of the up-and-down movement of the elevator floor 31 can be appropriately performed based on the detection signal of the door sill detector 39 arranged on the elevator floor 31. That is, when the tip of the lift floor 31 moves on the same plane as the door sill 202A of the getting on / off portion 202 so that there is no step between the door sill 202A of the getting on / off portion 202 and the lift floor 31 of the cab 20, the lift floor The up-and-down movement of 31 can be stopped appropriately.

For example, when the cab 20 is mounted on the boarding / alighting part 202 of the aircraft 200, the level difference between the door sill 202A of the boarding / alighting part 202 and the raising / lowering floor 31 of the cab 20 depends on the mounting state of the cab 20 on the boarding / alighting part 202. It varies depending on the situation. Therefore, the above-described automatic control of the raising / lowering movement of the raising / lowering floor 31 is beneficial in terms of simplifying and speeding up the operation of the passenger boarding bridge 100 in combination with the automatic docking function of the conventional steps S1 to S7. .
(Modification)
In the passenger boarding bridge 100 of the present embodiment, the door sill detector 39 is configured so that the tip of the elevator floor 31 reaches the same plane as the door sill 202A of the passenger board 202 of the aircraft 200 while the elevator floor 31 moves up and down (up and down movement). Then, the example which outputs a detection signal is shown. However, in place of such an elevating floor 31, the step eliminating device 30 includes an oscillating floor (not shown) that oscillates with respect to the walking passage 21 of the cab 20 using an appropriate connecting hinge portion. It doesn't matter. In this modification, this swing floor is an example of a movable floor that is used for connection with the door sill 202A of the boarding / alighting unit 202 of the aircraft 200 and configured to be movable up and down.

The door sill detector 39 may output a detection signal when the tip of the rocking floor reaches the same plane as the door sill 202A of the boarding / alighting unit 202 of the aircraft 200 during the rocking of the rocking floor.

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 should be construed as illustrative only and is provided for the purpose of teaching those skilled in the art the best 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.

One embodiment of the present invention can appropriately perform automatic control of the movable floor movement of the cab. Thus, one embodiment of the present invention can be used as, for example, a passenger boarding bridge for aircraft.
