Description

The present invention relates to a boarding bridge.

A boarding bridge (PBB), also called a boarding bridge, is a tunnel-shaped walking passageway that connects an airport terminal building and an aircraft.By connecting the terminal building and the aircraft, passengers can board and alight directly. It has been made possible.

On the other hand, some small aircraft have built-in stairs for getting on and off the plane, called an Airstair. Such stairs for boarding and alighting are installed at the entrance and exit of the aircraft when the door is opened, and handrails are provided on both sides of the stairs for safety reasons. Some types of handrails have a structure that is difficult to fold, so it may be necessary to move the head of the boarding bridge closer to the aircraft entrance while the handrail remains upright.

Therefore, some boarding bridges have a crossing passage section installed at the tip of the head. Patent Document 1 listed below discloses a technique in which a floorboard main body is attached as a crossing passage section under the floor of a head of a boarding bridge, and the floorboard main body is pivotable between a storage position and a passageway forming position. When used on a small aircraft, a floorboard body is installed to form a boarding and alighting passageway without interfering with the built-in ramp.

JP 2016-41539 Publication

The floorboard body described in Patent Document 1 mentioned above pivots around the position (rotation axis) where it is attached to the head. When the boarding bridge is close to the aircraft, in order to make the longitudinal direction of the floor plate body parallel to the longitudinal direction of the boarding stairs, and to match the longitudinal axis of the floor board body and the longitudinal axis of the boarding stairs, it is necessary to It is necessary to adjust the orientation of the floorboard as well as the orientation of the floorboard itself.

Further, as shown in FIG. 69, when a crossing passage section 85 is installed at the tip of the head 84 of the boarding bridge 81, when the traveling section is driven to bring the head 84 closer to the aircraft, the tunnel section 83 and the head 84 will move around the rotunda 82 on the terminal building side. Therefore, the orientation of head 84 with respect to aircraft 90 is changed. Therefore, in order to make the longitudinal axis of the passageway part 85 coincide with the longitudinal axis of the boarding stairs 91 installed at the entrance 92 of the aircraft 90, it is necessary to need to be adjusted again.

Furthermore, after aligning the longitudinal axis of the passageway section 85 with the longitudinal axis of the boarding and alighting stairs 91 installed at the entrance 92 of the aircraft 90, the tip of the passageway section 85 and the aircraft 90 are aligned. If the entrance/exit 92 is far away, it is necessary to move the passageway section 85 closer to the entrance/exit 92. This operation is performed by the running section of the boarding bridge 81. However, since the traveling section needs to drive the tunnel section 83 and head 84, which are heavy, the startup and movement speeds are slow, making it difficult to perform a quick approach operation.

Furthermore, although it is necessary to perform a series of these grounding operations quickly and smoothly, the operator must have sufficient experience, and it is extremely difficult to connect the aircraft and the boarding bridge.

The present invention has been made in view of the above circumstances, and provides a boarding bridge that can be quickly and easily connected to an aircraft entrance when the head has a passage section extending to the tip of the head. The purpose is to provide.

In order to solve the above problems, the boarding bridge of the present invention employs the following means.
That is, the boarding bridge according to the present invention includes a tunnel section, a head section installed at one end of the tunnel section so as to be pivotable with respect to the tunnel section, and a head section that is movable in and out of the head section at one end of the head section. moving the main body plate in a plane parallel to the plate surface of the installed main body plate that is long in one direction and perpendicular to the longitudinal direction of the main body plate; and a drive unit that moves the main body plate between a height position below the lower surface of the head part and a height position above the floor surface of the head part , the main body plate: At a height position above the floor surface of the head section, the head section is movable in the front-back direction of the head section, and is moved toward the head section and positioned above the floor surface of the head section. , and may move forward of the head and protrude beyond the tip of the head .

According to this configuration, the head section is rotatable relative to the tunnel section at one end of the tunnel section, and the elongated main body plate is installed at one end of the head section so as to be able to move in and out of the head section. . Further, the main body plate is moved by the drive unit in a plane parallel to the plate surface of the main body plate and in a direction perpendicular to the longitudinal direction of the main body plate. The main body plate and the drive section constitute a crossing passage section. Therefore, when the boarding bridge approaches the aircraft, the head section is rotated so that the longitudinal direction of the main board is parallel to the longitudinal direction of the boarding stairs, and then the boarding bridge is moved in a direction perpendicular to the longitudinal direction of the main board. As a result, the longitudinal axis of the main body plate and the longitudinal axis of the boarding/exiting stairs can be made to coincide with each other. If the main body plate is advanced in the longitudinal direction relative to the head part in this state, the main body plate can be brought closer to the aircraft, so that the head part can be quickly connected to the aircraft.

In the above invention, the main body plate may be configured to be able to be installed outside a width direction end portion of the head portion by movement by the drive unit.

According to this configuration, as the main body plate is moved by the drive unit and is installed outside the widthwise end of the head unit, it is possible to place the main body plate at the entrance or exit of the aircraft at a location away from the position where the head unit can be installed. The main body plate can be moved closer to the aircraft even when a staircase is located.

In the above invention, an auxiliary plate may be provided between the main body plate installed outside the width direction end portion of the head portion and the head portion.

According to this configuration, when the main body plate is installed outside the width direction end of the head part, since the auxiliary plate is installed between the main body plate and the head part, the head part It becomes possible to pass between the section and the main body plate.

The above invention may further include a movable roof that is installed on the top of the head part and is movable between a storage position located on the top of the head part and an extended position that covers the main body plate extended from the head part. good.

According to this configuration, the movable roof installed on the top of the head is movable between the storage position located on the top of the head and the extended position that covers the main body plate extended from the head, When the plate advances from the head part, the main body plate can be covered by the movable roof.

The above invention may further include a handrail installed on the main body plate.

According to this configuration, the handrail is installed on the main body plate. For example, the handrail can be rotated about a rotation axis parallel to the width direction of the main body plate, and can be tilted down to be located below the floor surface of the main body plate.

In the above invention, the main body plate may be installed at one end of the head portion so as to be pivotable with respect to the head portion.

According to this configuration, the main body plate is rotatably installed at one end of the head portion, and the installation direction of the main body plate can be changed while maintaining the installation direction of the head portion.

According to the present invention, in the case where the head portion has a passage portion extending across the tip thereof, connection to an aircraft entrance can be quickly and easily made.

[First embodiment]
The boarding bridge 1 according to the first embodiment of the present invention forms a passageway for passengers between the terminal building of an airport and the aircraft 90, connects the terminal building and the aircraft 90, and allows passengers to board and alight directly. enable.
The boarding bridge 1 moves, for example, between a standby position for connection preparation before the arrival of the aircraft 90 and a connection position when connected to the aircraft 90.

As shown in FIG. 1, the boarding bridge 1 is connected to a rotunda 2 fixedly provided to a terminal building or a fixed bridge leading to the terminal building, and is rotatably connected to the rotunda 2 in horizontal and vertical directions. A proximal tunnel 3a, a movable distal tunnel 3b that is nestedly fitted to the outside of the proximal tunnel 3a on the distal end side (aircraft 90 side) of the proximal tunnel 3a, and fixed to the distal end of the distal tunnel 3b. The head (head portion) 4 and the like are provided.

A movable leg 5 is provided on the distal end side in the longitudinal direction of the distal end tunnel 3b. The movable leg 5 is provided with a pair of left and right supports 11 that are attached to both sides of the distal end tunnel 3b and extend in the vertical direction. A fixed leg 6 is installed at the bottom of the rotunda 2 to be fixed to the ground. The boarding bridge 1 is supported by movable legs 5 and fixed legs 6. The proximal tunnel 3 a and the distal tunnel 3 b constitute a tunnel section 3 , and the tunnel section 3 and head 4 are movable by movable legs 5 . Note that the rotunda 2 may be supported by the terminal building and the fixed legs 6 may not be installed at the bottom.

The cross-sectional area of the hollow portion of the distal tunnel 3b is larger than the cross-sectional area of the proximal tunnel 3a. The distal tunnel 3b moves along the outer peripheral surface of the proximal tunnel 3a. When the tip tunnel 3b moves toward the side where the aircraft 90 is parked, the total length of the tunnel portion 3 increases, and when the tip tunnel 3b moves toward the rotunda 2 side, the total length of the tunnel portion 3 contracts. Note that the tunnel section of the present invention is not limited to a combination of two tunnel sections, the proximal tunnel 3a and the distal tunnel 3b, and may be one in which three or more tunnel sections are connected and have two or more stages of expansion and contraction mechanisms. good.

The base end tunnel 3a is rotatable around a rotation axis provided in the rotunda 2 and parallel to the vertical direction. Therefore, the base end tunnel 3a, the distal end tunnel 3b, and the head 4 are rotatable in a horizontal plane, for example, in the left-right direction about the rotation axis.

The distal end tunnel 3b moves in the longitudinal direction and left/right direction of the proximal end tunnel 3a and the distal end tunnel 3b by driving the traveling portion 7 provided on the movable leg 5 and moving the movable leg 5.

The base end tunnel 3a is rotatable around a rotation axis provided in the rotunda 2 and parallel to the horizontal direction. The movable leg 5 can be adjusted in the height direction of the distal end tunnel 3b by a lifting device 10. The lifting device 10 includes, for example, a motor and a ball screw mechanism. Therefore, the height of the movable leg 5 is adjusted, and the proximal end tunnel 3a, the distal end tunnel 3b, and the head 4 are tilted according to the height of the aircraft 90 by vertically rotating around the rotation axis. be done.

In this way, the boarding bridge 1 expands and contracts and rotates in the horizontal and vertical directions around the rotation axis provided in the rotunda 2, so the boarding bridge 1 can be properly connected to the aircraft 90.

The head 4 has an opening formed at its distal end, and the distal end is connected to an entrance/exit 92 of an aircraft 90 . An operation panel 9 is provided inside the head 4 to start driving the running section 7 of the boarding bridge 1 and to control the running direction (steering angle) of the wheels 8 in the running section 7.

Note that inside the rotunda 2, the proximal end tunnel 3a, the distal end tunnel 3b, and the head 4 of the boarding bridge 1, a passage for passengers to pass is provided from the rotunda 2 to the head 4.

A support beam 12 extending horizontally is fixedly attached to the lower end portions of the pair of support columns 11 so as to connect them. Wheels 8 attached to the lower part of the support beam 12 at the extended position of the support column 11 are installed on the running section 7 . The wheels 8 are four wheels or two wheels.

As shown in FIGS. 2 to 5, a crossing passage section 13 is installed at the tip of the head 4, and the crossing passage section 13 forms a part of the boarding passage between the head 4 and the boarding/exiting door 92 of the aircraft 90. do. The crossing passage section 13 includes a main body plate 14, a drive mechanism 15, and the like.

The drive mechanism 15 includes a support frame 16, a beam 17, a bracket 18, a plate drive section, a support frame drive section, a beam drive section, a bracket drive section, and the like.

The main body plate 14 is a plate-shaped member having sufficient strength as a boarding and alighting passage. The main body plate 14 is a long plate-like member that is elongated in one direction, and one end side is provided to and supported by the support frame 16, and the other end side is connectable to the entrance/exit 92 of the aircraft 90. There is. A handrail is installed at the side end of the main body plate 14. Note that the same handrail as the handrail 60 described in the second embodiment can be used.

The support frame 16 is a member that is attached to the beam 17 below the head 4 and extends further forward of the head 4 than the beam 17 . When the support frame 16 is viewed from above, the support frame 16 extends linearly in the front-rear direction of the head 4 from the base end connected to the beam 17 to the distal end of the support frame 16, as shown in FIG. ing. Thereby, the main body plate 14 moves inside both ends of the head 4 in the width direction.

A main body plate 14 is movably installed on the support frame 16. As shown in FIGS. 6 to 9, in the support frame 16, the main body plate 14 moves in a direction parallel to the longitudinal direction of the main body plate 14, that is, in the front-rear direction of the head 4. As shown in FIGS.

The beam 17 is a long member. The beam 17 is installed on the bracket 18 so that the longitudinal direction of the beam 17 is perpendicular to the longitudinal direction of the main body plate 14, that is, parallel to the width direction of the head 4. A support frame 16 is movably supported by the beam 17, and the support frame 16 slides along the longitudinal direction of the beam 17, as shown in FIG.

The bracket 18 is a member that is attached to the lower surface of the head 4 and extends in a direction perpendicular to the lower surface of the head 4. The bracket 18 is movably installed on the lower surface of the head 4 and supports the beam 17. As shown in FIGS. 6 to 9, the beam 17 is installed in the bracket 18 so as to be movable in the vertical direction. Further, the bracket 18 is movable in the front-rear direction of the head 4, that is, in the direction perpendicular to the width direction of the head 4.

The plate driving section moves the main body plate 14 on the support frame 16 in a direction parallel to the longitudinal direction of the main body plate 14. The plate drive unit includes an electric motor and a drive mechanism (eg, a ball screw mechanism, a belt/pulley mechanism, etc.). When the plate driving section is driven, the main body plate 14 moves relative to the support frame 16, and when the plate driving section stops driving, the movement of the main body plate 14 in the support frame 16 is stopped.

The support frame drive section moves the support frame 16 along the longitudinal direction of the beam 17. The support frame drive unit includes an electric motor and a drive mechanism (eg, a ball screw mechanism, a belt/pulley mechanism, etc.). When the support frame drive section is driven, the support frame 16 moves along the beam 17, and when the support frame drive section stops driving, the movement of the support frame 16 along the beam 17 is stopped.

The beam driving section moves the beam 17 along the bracket 18 in the vertical direction, that is, in the direction perpendicular to the lower surface of the head 4. The beam drive unit includes an electric motor and a drive mechanism (eg, a ball screw mechanism, a belt/pulley mechanism, etc.). When the beam driving section is driven, the beam 17 moves vertically along the bracket 18 on the lower surface of the head 4, and when the beam driving section stops driving, the beam 17 moves along the bracket 18. Stop.

The bracket drive unit moves the bracket 18 in the front-rear direction of the head 4, that is, in the direction perpendicular to the width direction of the head 4. The bracket drive unit includes an electric motor and a drive mechanism (eg, a ball screw mechanism, a belt/pulley mechanism, etc.). When the bracket drive section is driven, the bracket 18 moves in the front-back direction along the lower surface of the head 4, and when the bracket drive section stops driving, the movement of the bracket 18 along the lower surface of the head 4 is stopped. .

Next, the operation regarding the head 4 of the boarding bridge 1 according to this embodiment will be explained.
First, the head 4 is installed near the aircraft 90 by driving the traveling section 7 and moving the movable legs 5. At this time, as shown in FIG. 3, the orientation of the head 4 is adjusted to make the longitudinal direction of the main body plate 14 and the longitudinal direction of the boarding/exiting stairs 91 parallel.

As a result, if the longitudinal axis of the main body plate 14 and the longitudinal axis of the boarding stairs 91 match, the main body plate 14 can be advanced in the longitudinal direction relative to the head 4 by the plate driving section. , the main body plate 14 can be brought closer to the aircraft 90.

On the other hand, as shown in FIG. 3, when the longitudinal axis of the main body plate 14 and the longitudinal axis of the boarding/exiting stairs 91 do not match, the support frame driving section moves the support frame 16 in the longitudinal direction of the beam 17. move along.

As a result, the main body plate 14 installed on the support frame 16 slides in a direction perpendicular to the longitudinal direction of the main body plate 14 while maintaining the orientation of the main body plate 14. Thereby, as shown in FIG. 4, the longitudinal axis of the main body plate 14 and the longitudinal axis of the boarding/exiting stairs 91 can be made to coincide with each other. With the longitudinal axis of the main body plate 14 and the longitudinal axis of the boarding stairs 91 aligned, the main body plate 14 is advanced in the longitudinal direction toward the head 4 by the plate driving section, as shown in FIG. This allows the main body plate 14 to be brought closer to the aircraft 90.

From the above, after making the longitudinal direction of the main body plate 14 parallel to the longitudinal direction of the stairs 91 for getting on and off, when aligning the longitudinal axis of the main body plate 14 and the longitudinal axis of the stairs 91 for getting on and off, the main body plate Since it is only necessary to adjust the position of the main body plate 14 without adjusting the angle of the main body plate 14, the head 4 can be quickly connected to the aircraft 90. In addition, since the relatively lightweight main body plate 14 advances in the longitudinal direction toward the head 4 by the plate driving unit, the traveling unit 7 drives the heavy proximal end tunnel 3a, distal end tunnel 3b, etc., and the head The head 4 can be connected to the aircraft 90 in a shorter time than when the head 4 is connected to the aircraft 90.

Conventionally, when connecting the main body plate 14 to a small aircraft, the tunnel part and the head swing left and right, and there is a possibility that the crossing passage part comes into contact with the stair handrail 93 provided on the aircraft 90. If the running part of the boarding bridge had two wheels, the shaking would be large, so the running part needed to have four wheels. Furthermore, conventionally, when connecting the crossing passage section to the aircraft 90, it was necessary to drive the running section.

In the first embodiment described above, the main body plate 14 is moved in the front-rear direction of the head 4 by the drive of the plate drive unit, so the running unit 7 is not used when connecting the main body plate 14 to the aircraft 90. Therefore, when connecting the main body plate 14 to the aircraft 90, the running section 7 can be fixed by the outriggers. In this embodiment, since movement of the main body plate 14 by the running section 7 is not necessary, when the shaking is suppressed by the outriggers, the running section 7 can have two wheels.

Furthermore, when the main body plate 14 is configured to slide along the beam 17 in a direction perpendicular to the longitudinal direction of the main body plate 14, the main body plate 14 pivots about the installation position with the head 4 as a fulcrum. , it is easier to set the movable range of the head 4 in the width direction of the main body plate 14 to be larger than when the angle of the main body plate 14 is adjusted.

In addition, when the head 4 is brought close to the stair handrail 93 by the running part 7, the height position of the main body plate 14 retracted to the head 4 side may be lower than the lower surface of the head 4, as shown in FIG. Alternatively, as shown in FIG. 9, it may be above the floor surface of the head 4.

As shown in FIG. 9, when the height position of the main body plate 14 retracted toward the head 4 is set above the floor surface of the head 4, first, by driving the plate driving section, the state shown in FIG. 6 is changed from the state shown in FIG. As shown in 7, the main body plate 14 housed below the head 4 is moved to the front of the head 4 so as to protrude beyond the tip of the head 4. Then, as shown in FIG. 8, the main body plate 14 is moved above the floor surface of the head 4, and as shown in FIG. 9, the main body plate 14 is retracted to the head 4 side again. In this state, the head 4 is brought close to the stair handrail 93 by the traveling section 7.

Then, as shown in FIG. 3, the main body plate 14 is moved in the width direction of the head 4 so that the longitudinal axis of the main body plate 14 and the longitudinal axis of the boarding/exiting stairs 91 are aligned. Next, as shown in FIG. 10, the main body plate 14 located above the floor surface of the head 4 is moved forward of the head 4 so that it protrudes beyond the tip of the head 4, and the main body plate 14 is moved to the aircraft 90. Connect to. When the main body plate 14 is connected to the aircraft 90, the height of the main body plate 14 may be changed to match the floor surface of the head 4, as shown in FIG. A spanning board 19 may be installed on the upper surface of the floor surface of the board 14 and the head 4.

Further, as shown in FIG. 6, when the height position of the main body plate 14 retracted to the head 4 side is set below the floor surface of the head 4, the main body plate 14 is retracted to the head 4 side. In this state, the head 4 is brought close to the stair handrail 93 by the traveling section 7.

Then, as shown in FIG. 3, the main body plate 14 is moved in the width direction of the head 4 so that the longitudinal axis of the main body plate 14 and the longitudinal axis of the boarding/exiting stairs 91 are aligned. Next, as shown in FIG. 13, the main body plate 14 located below the lower surface of the head 4 is moved forward of the head 4 so that it protrudes beyond the tip of the head 4. Thereafter, the height of the main body plate 14 is adjusted to match the height of the main body plate 14 to the floor surface of the head 4, as shown in FIG. Then, with the heights of the floor surfaces of the main body plate 14 and the head 4 matching, the height of the head 4 is adjusted, and the main body plate 14 is connected to the aircraft 90 as shown in FIG.
Note that the operation of the crossing passage section 13 described above is an example, and the present invention is not limited to this example.

[Second embodiment]
Next, a boarding bridge 1 according to a second embodiment of the present invention will be described. Note that detailed explanations of configurations and effects that overlap with those of the first embodiment described above will be omitted.

In the first embodiment described above, as shown in FIG. 2, a configuration has been described in which the main body plate 14 is movable inside both ends of the head 4 in the width direction, but the present invention is not limited to this example.

In the first embodiment, when the support frame 16 is viewed from above, the support frame 16 extends linearly in the front-rear direction of the head 4 from the base end connected to the beam 17 to the distal end of the support frame 16. There is. In contrast, as shown in FIG. 17, the support frame 16 of this embodiment extends in the front-rear direction of the head 4, and is bent and extends parallel to the width direction of the head 4. . As shown in FIG. 16, in the case of a boarding bridge 1 in which the head 4 is connected to the left side of an aircraft 90, the support frame 16 has a bent portion 16a on the right side in the traveling direction of the head 4, as shown in FIG. The tip of the support frame 16 can be installed outside the right end of the head 4 in the direction of movement, and the main body plate 14 is installed at the tip of the support frame 16.

When the support frame 16 is linear as in the first embodiment, in order to install the tip of the support frame 16 outside the right end in the direction of movement of the head 4, the beam 17 must be placed in the direction of movement of the head 4. It needs to extend outward beyond the right edge. In contrast, in this embodiment, the main body plate 14 can be installed outside the right end of the head 4 in the direction of travel without extending the beam 17 outside of the right end of the head 4 in the direction of travel.

As shown in FIG. 17, some small aircraft 90 have a propeller installed in front of the main wing, or have an entrance/exit 92 near the main wing. In that case, the head 4 cannot be brought close to the position where it can oppose the entrance/exit door 92. In such a case, since the main body plate 14 according to the present embodiment is installed outside the widthwise end of the head 4, the boarding/exit 92 of the aircraft 90 is located outside the position where the head 4 can be installed. The main body plate 14 can be brought close to the aircraft 90 even when the boarding/exiting stairs 91 are located.

In this embodiment, when the main body plate 14 is installed outside the widthwise end of the head 4, a gap is formed between the main body plate 14 and the head 4, so as shown in FIG. An auxiliary plate 20 is installed to close the gap formed between the head 14 and the head 4. By installing the auxiliary plate 20 between the main body plate 14 and the head 4, passage between the head 4 and the main body plate 14 is made possible via the auxiliary plate 20.

The auxiliary plate 20 is a long plate-like member. The auxiliary plate 20 is installed, for example, in front of the head 4, as shown in FIGS. 16 and 17, and the longitudinal direction of the auxiliary plate 20 is parallel to the width direction of the head 4. When moving from the boarding bridge 1 to the aircraft 90, passengers move from the front of the head 4 to the auxiliary board 20, then pass over the auxiliary board 20, move on the main body board 14, and then board the aircraft 90. .

The auxiliary plate 20 is provided on the second support frame 21 and is supported by the second support frame 21 .

The second support frame 21 is a member that is attached to the beam 17 and extends further forward of the head 4 than the beam 17 . The second support frame 21 is supported under the floor of the head 4. The second support frame 21 is movable in the width direction of the head 4 via the beam 17. Further, the second support frame 21 is movable in the vertical direction via the bracket 18.

As shown in FIGS. 18 and 19, the second support frame 21 is installed such that its frame portion is rotatable. The axial direction of the rotation axis is parallel to the width direction of the head 4. Thereby, the auxiliary plate 20 can be stored below the head 4 by rotating the auxiliary plate 20 around the rotation axis and moving it downward.

Alternatively, as shown in FIGS. 20 and 21, the auxiliary plate 20 is slidably installed on the second support frame 21. The auxiliary plate 20 is configured to be movable in the front-rear direction of the head 4 in the second support frame 21 .
Note that a transition plate 22 may be installed between the auxiliary plate 20 and the floor surface of the head 4, and a transition plate 23 may be installed between the main body plate 14 and the floor surface of the auxiliary plate 20.

Further, as shown in FIG. 22, the auxiliary plate 24 may be installed, for example, on the side of the head 4. The longitudinal direction of the auxiliary plate 24 is parallel to the front-rear direction of the head 4. When a passenger moves from the boarding bridge 1 to the aircraft 90, the passenger moves from the side of the head 4 to the auxiliary plate 24, passes through the auxiliary plate 24, moves to the main body plate 14, and then boards the aircraft 90.

The auxiliary plate 24 is movably supported by a third support frame 25, a bracket 26, a frame drive section, and a bracket drive section. The auxiliary plate 24 is movable in the width direction of the head 4 and in the vertical direction.

The auxiliary plate 24 is provided on the third support frame 25 and is supported by the third support frame 25.

The third support frame 25 is attached to a bracket 26. In the bracket 26, the third support frame 25 is installed so as to be movable in the up and down direction (vertical direction). Further, the bracket 26 is movable in the width direction of the head 4. By moving the auxiliary plate 24 vertically and horizontally of the head 4, the auxiliary plate 24 can be stored below the head 4 as shown in FIGS. 23 and 25, or As shown in 24, the head 4 can be installed at a height that matches the floor surface of the head 4.

The frame drive unit moves the third support frame 25 along the bracket 26 in the vertical direction, that is, in the direction perpendicular to the lower surface of the head 4, as shown in FIGS. 26 and 27. The frame drive unit includes an electric motor and a drive mechanism (eg, a ball screw mechanism, a belt/pulley mechanism, etc.). When the frame drive section is driven, the third support frame 25 moves vertically along the bracket 26 on the lower surface of the head 4, and when the frame drive section stops driving, the beam 17 moves along the bracket 26. movement stops.

The bracket drive section moves the bracket 26 along the width direction of the head 4, as shown in FIGS. 26 and 27. The bracket drive unit includes an electric motor and a drive mechanism (eg, a ball screw mechanism, a belt/pulley mechanism, etc.). When the bracket driving section is driven, the bracket 26 moves in the width direction of the head 4 along the lower surface of the head 4, and when the bracket driving section stops driving, the bracket 26 moves along the lower surface of the head 4. stops.

Note that in the bracket 26, the third support frame 25 is not movable in the vertical direction (vertical direction), but may be fixed in position in the height direction, as shown in FIGS. 29 and 30. In this case, the bracket 26 is movable in the width direction of the head 4 while maintaining its height. In this configuration, the auxiliary plate 24 is configured to be rotatable around the axis of the hinge 27. The axial direction of the rotation axis of the hinge 27 is parallel to the front-rear direction of the head 4. This allows the auxiliary plate 24 to be folded along the side surface of the head 4 by rotating the auxiliary plate 24 around the rotation axis, as shown in FIGS. 28 to 30. Thereby, the auxiliary plate 24 can be moved to the vicinity of the head 4 to have a contracted shape.

Further, as shown in FIGS. 31 to 36, the auxiliary plate 24 may be configured to be pivotable in a plane parallel to the floor surface of the head 4. At this time, one end 24a of the auxiliary plate 24 is fixed to the head 4, and the other end 24b is movable in the width direction of the head 4. The auxiliary plate 24 is rotatably divided and composed of a plurality of members. Further, the auxiliary plate 24 has a structure that is rotatable around the axis of the hinge 27, as shown in FIGS. 35 and 36.

For example, as shown in FIG. 31, the auxiliary plate 24 is movable by engaging with the support frame 16 that supports the main body plate 14. Thereby, the auxiliary plate 24 is moved together with the support frame 16 in the width direction of the head 4, and the direction of the passage of the auxiliary plate 24 can be made straight or bent.

For example, when the auxiliary plate 24 is installed on the side of the head 4 and is movable in the width direction of the head 4, a slide plate 30 may be further installed as shown in FIGS. 22 to 30. The slide plate 30 is installed, for example, on the side of the head 4 and is movable within a plane parallel to the floor surface of the head 4.

A slide plate 30 is installed so as to close the gap formed between the main body plate 14 and the head 4. By installing the slide plate 30 between the auxiliary plate 24 and the head 4, passage between the head 4 and the auxiliary plate 24 is made possible via the slide plate 30.

As shown in FIGS. 37 and 38, the end of the slide plate 30 on the auxiliary plate 24 side may be configured to be able to engage with the end of the auxiliary plate 24 on the head 4 side. The auxiliary plate 24 moves to a predetermined height position (see FIG. 37) or rotates to a predetermined position (see FIG. 38), and the auxiliary plate 24 is installed at approximately the same height as the floor surface of the head 4. At this time, the slide plate 30 and the auxiliary plate 24 engage with each other. When the auxiliary plate 24 moves in the width direction of the head 4 while the slide plate 30 and the auxiliary plate 24 are engaged, the slide plate 30 also slides in the width direction of the head 4.

<Movable roof>
Next, the movable roof 28 applied to the boarding bridge 1 according to this embodiment will be explained.

At the top of the head 4, there is a storage position located at the top of the head 4 (positions indicated by two-dot chain lines in FIGS. 39 to 41 and FIG. 43), and a forwarding position that extends from the top of the head 4 to the upper side of the body of the aircraft 90. A movable roof 28 is installed, which is movable by sliding between the roof and the roof (positions indicated by solid lines in FIGS. 41 to 43). This movable roof 28 has an area that can reliably cover the upper part of the passageway section 13.

Further, the movable roof 28 is installed above the roof of the head 4 and is movable within a plane parallel to the upper surface of the roof. The movable roof 28 moves along, for example, a guide rail installed on the top surface of the roof of the head 4. The movable roof 28 can be moved back and forth along the guide rail by the operation of the drive mechanism. Note that the drive mechanism is not particularly limited, and may be, for example, a hydraulic jack, a slide mechanism using a ball screw driven by a motor, a rack and pinion mechanism, or the like.

When the boarding bridge 1 equipped with such a movable roof 28 is applied to a small aircraft 90, the boarding bridge 1 equipped with the movable roof 28 can be connected to the aircraft 90 by moving the movable roof 28 to the advanced position. It becomes possible to cover the upper part of the crossing passage section 13 connecting with the head 4 as a rain countermeasure.

39 to 42 show examples of the movable roof 28 that is applied when the main body plate 14 and the auxiliary plate 20 are installed in front of the head 4 in the crossover passage section 13. Further, FIG. 43 shows an example of a movable roof 28 that is applied when a main body plate 14 and an auxiliary plate 24 are installed on the sides of the head 4 in the crossover passage section 13.

In the example shown in FIGS. 39 and 40, the upper part of the passageway section 13 is covered by a movable roof 28 having an area approximately equal to the roof surface of the head 4, so that the influence of rainfall on passengers getting on and off is minimized. It becomes possible to suppress it. In the illustrated example, the movable roof 28 is used with the canopy 50 folded. Further, in the example shown in FIGS. 40 and 42, an upper curtain 29 is installed on the movable roof 28 on the aircraft 90 side.

In the example shown in FIGS. 41 and 42, the canopy 50 is brought close to the body of the aircraft 90, and the upper part of the crossing passage section 13 is covered by the movable roof 28. Furthermore, in the example shown in FIGS. 41 and 43, the movable roof 28 is provided with side walls 52 and side curtains 53 so as to be suspended from the movable roof 28. By providing the side walls 52 and side curtains 53, in addition to covering the upper part of the passageway with the movable roof 28, the sides of the passageway part 13 are also covered, so that wind on the passageway and the influence of the wind can be prevented. It can prevent the rain from entering.

When the canopy 50 is brought close to the aircraft body, the canopy 50 is lifted upward using a chain 51 so that the canopy 50 does not obstruct traffic, as shown in FIG.

Further, as shown in FIG. 40, the tip of the movable roof 28 described above may be moved to a position beyond the center axis of the fuselage of the aircraft 90 at the protruding position. In other words, if the tip of the movable roof 28 is located beyond the center axis of the fuselage of the aircraft 90, rainwater that falls from the tip of the movable roof 28 onto the circular cross-sectional body will flow to the side opposite to the entrance 92 of the aircraft 90. Since the rainwater falls down, it is possible to further reduce the impact of rainwater on passengers.

<Handrail>
Next, the handrail 60 applied to the boarding bridge 1 according to this embodiment will be explained.

For example, as shown in FIG. 44, the handrail 60 (60A) is installed on the main body plate 14 and is rotatable about a rotation axis 61 parallel to the width direction of the main body plate 14. As shown in FIG. 45, while the main body plate 14 moves in the longitudinal direction and approaches the aircraft 90, the handrail 60A is configured such that the support column 62 is above the floor surface of the main body plate 14 and is not on the aircraft 90 side. Stand up by leaning to the opposite side. At this time, it is desirable that the handrail 60A is tilted to a position where the main body plate 14 is closest to the aircraft 90 and the lower surface of the handrail 60A does not overlap the stair handrail 93 of the aircraft 90.

When the handrail 60A is used, it is erected by rotating the supports 62 of the handrail 60A, as shown in the dashed line in FIG. 44 and in FIG. 46. Further, when the main body plate 14 is housed in a position retracted from the tip of the head 4, the handrail 60A is such that the support column 62 is positioned below the floor surface of the main body plate 14, as shown in the solid line part in FIG. 44 and in FIG. It rotates like this and is knocked down.

Thereby, even if the handrail 60A has a rectangular frame, the main body plate 14 is moved toward the aircraft 90 so that the handrail 60A provided on the main body plate 14 and the stair handrail 93 of the aircraft 90 do not come into contact with each other. be able to.

As shown in FIG. 45, the handrail 60 provided on the main body plate 14 may be provided with a cover 63 that blocks the passage side and the outside side.

The handrail 60 is configured to be foldable or extendable in the following manner. Below, a case where the handrail 60 is applied to the main body plate 14 will be described. Note that the handrail 60 can also be applied to the auxiliary plates 20 and 24 or the slide plate 30.
For example, as shown in FIG. 48, a hinge 64 is provided at the base of the column 62 of the handrail 60 (60B). The rotation axis of the hinge 64 is parallel to the longitudinal direction of the main body plate 14. As a result, the handrail 60B can be folded inward in the width direction of the main body plate 14 (FIGS. 48(A), (C)) or outward in the width direction of the main body plate 14 (FIGS. 48(A), ( C), (D)). Furthermore, when the handrail 60B is folded outward in the width direction of the main body plate 14, as shown in FIG.

Further, as shown in FIGS. 49 and 50, the handrail 60C is installed on the main body plate 14 so that the handrail 60C can rotate around the support column 62 of the handrail 60 (60C). As a result, the handrail 60C rotates about the support 62 provided perpendicularly to the floor surface of the main body plate 14 as a rotation axis. Further, a hinge 66 may be provided in the arm portion 65. The axis of rotation of the hinge 66 is perpendicular to the floor surface of the main body plate 14. Thereby, the arm portions 65 of the handrail 60C overlap, and the arm portions 65 can be folded in multiple stages, for example, in two stages.

Furthermore, as shown in FIG. 51, the arm portion 65 of the handrail 60 (60D) may be configured to be expandable and retractable in a direction parallel to the axial direction of the main body plate 14. Further, as shown in FIG. 52, when the arm portion 65 has a telescopic structure, the lower end 62A of the support column 62 is fixed to the tip of the main body plate 14 that moves in parallel, so that when the main body plate 14 moves in parallel, the handrail 60D expands and contracts as the main body plate 14 moves in parallel.

Note that FIGS. 53 to 57 show examples of combinations of handrails 60 installed on the main body plate 14 and the auxiliary plates 20, 24. In addition, in the present invention, the installation example of the handrail 60 is not limited to the illustrated example.

53 to 56 show examples of the arrangement of handrails 60 that are applied when the main body plate 14 and the auxiliary plate 20 are installed in front of the head 4 in the crossing passage section 13.

For example, a handrail 60A having a rotatable structure shown in FIG. 44 is installed on one side of the main body plate 14, and a handrail 60A having a rotatable structure shown in FIG. 44 is installed on the other side of the main body plate 14. At the same time, handrails 60A+60D having an expandable structure shown in FIG. 51 are installed. When the auxiliary board 20 is installed, the handrails 60A+60D are in a contracted and stored state. In addition, in the auxiliary plate 20, a handrail 60B having a structure that can be rotated inwardly and outwardly as shown in FIG. 48 is installed on one side in the transverse direction and one side in the longitudinal direction. On the other side of the direction, handrails 60B+60C are installed, which have a structure that can rotate inward or outward as shown in FIG. 48, and also have a structure that can rotate around the support column 62 shown in FIG. be done.
Handrails 60C+60D are installed on the floor surface of the head 4, and have a structure that can be rotated inwardly or outwardly as shown in FIG. 49, and have an extendable structure as shown in FIG. 51.

Further, FIG. 57 shows an example of a handrail 60 that is applied when the main body plate 14, the auxiliary plate 24, and the slide plate 30 are installed on the sides of the head 4 in the crossing passage section 13.

For example, handrails 60A having a rotatable structure shown in FIG. 44 are installed on both sides of the main body plate 14. In the auxiliary plate 24, a handrail 60B having a structure capable of rotating inwardly and outwardly as shown in FIG. 48 is installed on one side in the transverse direction and one side in the longitudinal direction, respectively. On the other side of the direction, handrails 60B+60D are installed, which have a structure that can be rotated inwardly or outwardly as shown in FIG. 48, and have an extendable structure shown in FIG. 51. On both sides of the slide plate 30, handrails 60C+60D are installed, which have a structure that is rotatable around the pillars shown in FIG. 49 and also have an extendable structure shown in FIG. 51.

Conventionally, when connecting the main body plate 14 to a small aircraft, the tunnel section and the head swing from side to side, and the handrail installed in the passageway or the passageway comes into contact with the stair handrail 93 provided on the aircraft 90. there is a possibility. If the running part of the boarding bridge had two wheels, the shaking would be large, so the running part needed to have four wheels. Furthermore, conventionally, when connecting the crossing passage section to the aircraft 90, it was necessary to drive the running section.

In the second embodiment described above, the main body plate 14 is moved in the front-rear direction of the head 4 by the drive of the plate drive unit, so the running unit 7 is not used when connecting the main body plate 14 to the aircraft 90. Therefore, when connecting the main body plate 14 to the aircraft 90, the running section 7 can be fixed by the outriggers. In this embodiment, since movement of the main body plate 14 by the running section 7 is not necessary, when the shaking is suppressed by the outriggers, the running section 7 can have two wheels.

[Third embodiment]
Next, a boarding bridge 1 according to a third embodiment of the present invention will be described.
A crossing passage section 31 is installed in the head 4, and the crossing passage section 13 forms a part of the boarding passage between the head 4 and the boarding/disembarking entrance 92 of the aircraft 90. As shown in FIGS. 58 and 59, the crossing passage section 31 includes a main body plate 32, a drive mechanism 33, and the like.

The drive mechanism 33 includes a support frame 34, a tip support base 35, a first swing drive mechanism 36, a second swing drive mechanism, a plate drive section, and the like.

The main body plate 32 can be rotated around the attachment position with the head 4, and the main body plate 32 can be rotated in the longitudinal direction of the main body plate 32 while its orientation with respect to the head 4 is changed, or while maintaining the orientation of the main body plate 32. move in a direction perpendicular to. Therefore, the main body plate 32 is movable in a direction parallel to the width direction of the head 4 without changing the orientation of the main body plate 32. The main body plate 32 is slidable in the front-rear direction of the head 4, as will be described later. The main body plate 32 is a plate-shaped member having sufficient strength as a boarding and alighting passage. The main body plate 32 is a plate-like member that is long in one direction, and is provided on the tip support base 35, and the other end side can be connected to the entrance/exit 92 of the aircraft 90. A handrail is installed at the side end of the main body plate 32.

The drive mechanism 33 is attached under the floor of the head 4 and includes a support frame 34 that supports a tip support stand 35, a tip support stand 35 supported by the support frame 34, and the like.

The support frame 34 is supported under the floor of the head 4 so as to be able to pivot on a plane parallel to the floor of the head 4 with the rotation axis 34A as a fulcrum (rotation center).

The first swing drive mechanism 36 swings the support frame 34 relative to the head 4 . The first swing drive mechanism 36 has a position where the tip support stand 35 is stored in a position away from the tip side of the head 4, and a position where the tip support stand 35 is placed when connected to the aircraft 90, as shown in FIG. Rotate between positions. As a result, the support frame 34 moves between a storage position where it is retracted from the front end side of the head 4 and a passage forming position where a passage is formed between the entrance 92 and the head 4.

The first swing drive mechanism 36 uses, for example, an electric cylinder 37 as a drive source. The cylinder 37 has a rod 38 that expands and contracts electrically. The cylinder 37 has one end connected to the head 4 by pin connection, and the other end connected to the support frame 34 via a rod 38. As a result, the support frame 34 is placed in the storage position with the rod 38 contracted, and placed in the passage forming position with the rod 38 expanded. The first swing drive mechanism 36 can be actuated by a switch operation or the like to swing the tip support base 35 and the main body plate 32 to a desired position. In the operating state arranged when connected to the aircraft 90, the first swing drive mechanism 36 swings the support frame 34 through an angular range smaller than the movement of the support frame 34 described above, as shown in FIG. It is also possible to finely adjust the direction of the support frame 34.

The support frame 34 supports a tip support stand 35, and the tip support stand 35 is arranged in a plane parallel to the floor surface of the tip support stand 35 with respect to the support frame 34 with the rotation axis 35A as a fulcrum (rotation center). It is supported so that it can pivot upward. In the use state when connected to the aircraft 90, the tip support 35 can be rotated within a relatively small angular range, and the direction of the tip support 35 can be finely adjusted. The tip support stand 35 may be configured to be manually rotated around the rotation axis with respect to the support frame 34, or may be configured to be mechanically rotated by providing a second rotation drive mechanism (not shown).

The second rotation drive mechanism rotates the tip support base 35 with respect to the support frame 34. The second swing drive mechanism uses, for example, an electric cylinder as a drive source. The cylinder has a rod that expands and contracts electrically. One end of the cylinder is connected to the support frame 34 by pin connection, and the other end is connected to the tip support base 35 via a rod.

The support frame 34 includes, for example, an arm portion 39, a link mechanism 40, a cylinder 41, a bearing portion 42, and the like.
The arm portion 39 is an elongated member that is long in one direction, and has a rotating shaft 34A connected to the head 4 at one end, and a link mechanism 40 and a cylinder 41 connected to the other end. The arm portion 39 is installed on the lower surface of the head 4.

The rotation axis 34A is provided in a direction perpendicular to the floor surface of the head 4. The arm portion 39 pivots relative to the head 4 by rotating around the rotating shaft 34A. The arm portion 39 is mechanically rotated by the first rotation drive mechanism 36 that moves the arm portion 39 .

The link mechanism 40 has one end connected to the arm portion 39 and the other end connected to the bearing portion 42 . The link mechanism 40 has a configuration in which the height of the bearing portion 42, that is, the tip support base 35, can be adjusted with respect to the arm portion 39. The link mechanism 40 includes a drive link 40A connected to the cylinder 41, and a driven link 40B that operates in accordance with the movement of the drive link 40A. The cylinder 41 is, for example, an electric cylinder, and the link mechanism 40 is actuated by the cylinder 41, and the bearing part 42 is mechanically moved downward or upward. By moving the bearing part 42 upward, the heights of the floor surface of the main body plate 32 and the floor surface of the head 4 become the same, and by moving the bearing part 42 downward, the main body plate 32 is placed under the floor of the head 4. down to When the boarding bridge 1 is connected to the aircraft 90, the entire head 4 is raised and lowered by the movable legs 5 so that the upper surface of the main body plate 32 and the floor of the entrance/exit 92 of the aircraft 90 are aligned. The surface height is adjusted. At this time, the floor height of the main body plate 32 may be finely adjusted by operating the link mechanism 40.

The bearing portion 42 is a cylindrical member, and is connected to the link mechanism 40 on the side.

Further, the head 4 and the main body plate 32 are rotated so that the longitudinal axis of the main body plate 32 and the longitudinal axis of the boarding/exiting stairs 91 are made to coincide with each other. Then, the main body plate 32 is moved to the front of the head 4 and the main body plate 32 is connected to the aircraft 90.

Note that when the head 4 is brought close to the stair handrail 93 by the running section 7, the height position of the main body plate 32 retracted to the head 4 side is above the floor surface of the head 4, as shown in FIG. Alternatively, as shown in FIG. 64, it may be located below the lower surface of the head 4.

As shown in FIG. 61, when the height position of the main body plate 32 that has been retracted toward the head 4 is set above the floor surface of the head 4, first, the head is moved from the state shown in FIG. The main body plate 32 stored below the head 4 is moved to the front of the head 4 and is made to protrude beyond the tip of the head 4. Then, the main body plate 32 is moved above the floor surface of the head 4, and the main body plate 32 is retracted to the head 4 side as shown in FIG. 61. In this state, the head 4 is brought close to the stair handrail 93 by the traveling section 7.

Then, the longitudinal axis of the main body plate 32 and the longitudinal axis of the boarding/exiting stairs 91 are made to coincide with each other. Next, as shown in FIG. 62, the main body plate 32 located above the floor surface of the head 4 is moved forward of the head 4 so that it protrudes beyond the tip of the head 4, and the main body plate 32 is moved to the aircraft 90. Connect to. When the main body plate 32 is connected to the aircraft 90, the height of the main body plate 32 may be changed to match the floor surface of the head 4, as shown in FIG. A gangplank (not shown) may be installed on the upper surface of the surface.

Further, as shown in FIG. 64, when the height position of the main body plate 32 retracted to the head 4 side is set below the floor surface of the head 4, the main body plate 32 is retracted to the head 4 side. In this state, the head 4 is brought close to the stair handrail 93 by the traveling section 7.

Then, the longitudinal axis of the main body plate 32 and the longitudinal axis of the boarding/exiting stairs 91 are made to coincide with each other. Next, as shown in FIG. 65, the main body plate 32 located below the lower surface of the head 4 is moved forward of the head 4 so as to protrude beyond the tip of the head 4. Thereafter, the height of the main body plate 32 is adjusted to match the height of the main body plate 32 to the floor surface of the head 4, as shown in FIG. Then, with the heights of the floor surfaces of the main body plate 32 and the head 4 matching, the height of the head 4 is adjusted, and the main body plate 32 is connected to the aircraft 90 as shown in FIG.
Note that the operation of the crossing passage section 31 described above is an example, and the present invention is not limited to this example.

Further, the support frame 34 in the third embodiment may be installed on the beam 17 in the first and second embodiments. As a result, the main body plate 32 is rotatably installed relative to the head 4, and the main body plate 32 slides in a direction perpendicular to the longitudinal direction of the main body plate 32, that is, in the width direction of the head 4. do.

As explained below, the main body plate 14 according to the first and second embodiments may have a configuration that can be expanded or contracted in the width direction. Note that the auxiliary plates 20 and 24, the slide plate 30, and the main body plate 32 according to the third embodiment may have similar configurations.
During the operation of bringing the head 4 of the boarding bridge 1 close to the aircraft 90, the main body plate 14 is in a reduced state. When placed on the floor, the main body plate 14 is expanded.

Therefore, when the head 4 approaches the entrance/exit 92 of the aircraft 90, the main body plate 14 is reduced in the width direction as shown in FIG. 68(A). The handrail is less likely to come into contact with the stair handrail 93 of the stairs 91 for getting on and off, and the operation on the boarding bridge 1 side is facilitated. As a result, the moving speed of the boarding bridge 1 can be increased and the time required to complete the connection with the aircraft 90 can be shortened. Then, when the main body plate 14 is placed at a position where it is connected to the entrance/exit 92 of the aircraft 90, the main body plate 14 is expanded in the width direction, as shown in FIG. 68(B). It can provide customers with a wide aisle.
