Description

TECHNICAL FIELD This disclosure relates to boarding bridges.

A boarding bridge is, for example, a tunnel-like passageway that connects an airport and an aircraft, and allows passengers to board and alight directly between the terminal building and the aircraft. A boarding bridge includes a plurality of tunnel sections (passage sections) that are fitted together in a telescoping manner, and expands and contracts as these tunnel sections move relative to each other in the longitudinal direction. This allows for various spacings that may occur between the terminal building and the aircraft.

In order to operate the boarding bridge, the traveling device not only moves the head and tunnel toward the aircraft side, but also adjusts the head's rotation angle, height position, and horizontal direction depending on the position and angle of the aircraft boarding gate. It is necessary to adjust multiple items such as the position and the inclination angle of the floor of the head. Note that Patent Document 1 discloses a technique for moving a bumper provided at the front of the inclined floor of a cab (head).

International Publication No. 2018/055980

Conventionally, the floor of the head consists of a fixed floor fixed to the main body of the head, so in order to align the boarding gate of the aircraft with the opening of the head, the traveling gear of the boarding bridge must be moved. Therefore, it was necessary to adjust the position of the tunnel section and head. However, since the tunnel section turns around a fixed position on the terminal building side, the operator needs to move the traveling device in consideration of the turning trajectory of the head provided at the tip of the tunnel section. In other words, it is difficult to move the head linearly to the target position as seen by the operator, so the head is placed in advance at a position that assumes a turning trajectory, and the operation of approaching the aircraft from there (landing) )It is carried out.

The turning trajectory of the head is affected by the turning angle of the tunnel section at the time of contact, and the turning angle of the tunnel section changes depending on the installation position of the boarding bridge, the type of aircraft, and the position where the aircraft is stopped. . Therefore, in operating the boarding bridge, it is difficult to align the boarding gate of the aircraft with the opening of the head.

The present disclosure has been made in view of the above circumstances, and provides a boarding bridge that can quickly and easily adjust the direction of the tip of the head portion on the floor with respect to the boarding gate to which it is connected. The purpose is to

The boarding bridge 1 according to an embodiment of the present disclosure forms a passageway for passengers between an airport terminal building and an aircraft, connects the terminal building and the aircraft, and enables direct boarding and alighting of passengers. . The boarding bridge 1 moves, for example, between a standby position for connection preparation before the arrival of an aircraft and a connection position when connected to an aircraft.

As shown in FIG. 1, the boarding bridge 1 is connected to a rotunda 2 that is fixedly installed near 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 distal tunnel 3b that is telescopically fitted to the outside of the proximal tunnel 3a on the distal end side (aircraft side) of the proximal tunnel 3a and is movable, and a distal tunnel 3b that is fixed to the distal end of the distal tunnel 3b. The head 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 aircraft parking side, 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 portion of the present disclosure is not limited to a combination of two tunnel portions, the proximal tunnel 3a and the distal tunnel 3b, and may be one in which three or more tunnel portions are connected and have a two-stage or more expansion/contraction mechanism. 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 tunnel 3a, the distal tunnel 3b, and the head 4 are tilted according to the height of the aircraft by vertically rotating around the rotation axis. Ru.

In this way, the boarding bridge 1 expands and contracts and rotates horizontally and vertically around the rotation axis provided in the rotunda 2, so the boarding bridge 1 can be adjusted depending on the parking state of the aircraft. Can be properly connected to the aircraft.

The head 4 has an opening formed at its distal end, and the distal end is connected to the boarding gate of the aircraft. Inside the head 4, there are controls for starting or stopping the drive of the running section 7 of the boarding bridge 1, operating the running direction (steering angle) of the wheels 9 of the running section 7, and controlling the direction of the head 4. An operation panel (not shown) is provided for this purpose.

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.

The traveling section 7 includes, for example, two rubber wheels 9 and a wheel drive section (not shown) that rotationally drives the wheels 9. The two wheels 9 are fixedly attached to both ends of an axle that is rotatably supported around an axis parallel to the vertical direction. The wheel drive unit includes, for example, a travel motor with a reduction gear or a transmission mechanism.
Note that the traveling section 7 is not limited to the example described above, and for example, only one set of two wheels 9 may be provided, or two sets of two wheels 9 may be provided.

The running speed of the running section 7 can be adjusted by changing the rotational speed of the wheels 9. The turning angle (steering angle) of the wheels 9 in the running section 7 with respect to the length direction of the tip tunnel 3b is determined by the difference in rotational speed of the two wheels 9 and the rotational direction (direction) of the two wheels 9. It can be adjusted by changing the rotation or reversal.

The head 4 according to this embodiment will be described below.
The head 4 has a space inside which passengers can pass, and one side is connected to the tip of the tip tunnel 3b. The other side of the head 4 is formed with an opening and serves as a boarding/exit for passengers to enter and exit, and is connectable to an aircraft. The head 4 continuously connects the floor of the tip tunnel 3b and the floor of the boarding gate of the aircraft. The head 4 is pivotable relative to the tip tunnel 3b. Thereby, the opening of the head 4 can be directed toward the aircraft side regardless of the direction in which the tip tunnel 3b extends.

The head 4 includes a floor section 12, a cover section 13, and a canopy section 14, as shown in FIG. The head 4 has a function that allows the height and length of the floor portion 12 of the head 4 to be adjusted manually or automatically using sensors and mechanical mechanisms in response to vertical movement of the aircraft.

As shown in FIGS. 2 and 4, the floor section 12 includes a fixed floor 15, a movable floor 16, a movable floor drive section 17 provided below the movable floor 16, and an adjustable floor 18. , an adjustment bed drive section (for example, a hydraulic cylinder) (not shown) provided below the adjustment bed 18 is installed.

The fixed bed 15 is provided on the tunnel part 3 side of the head 4 and is fixed to the main body part 35 (see FIG. 9) of the floor part 12.

The movable floor 16 is, for example, a plate provided closer to the opening of the head 4 than the fixed floor 15, and as shown in FIGS. It is possible to move to The movable floor driving unit 17 can drive the movable floor 16 to move the movable floor 16 in the front-rear direction relative to the fixed floor 15. Here, the front-rear direction is a direction connecting the opening side of the head 4 and the tunnel part 3 side.

The movable floor drive unit 17 may include a first drive unit 17A provided at one end of the movable floor 16 in the width direction, and a second drive unit 17B provided at the other end of the movable floor 16 in the width direction. The first drive section 17A moves one end of the movable floor 16 in the width direction in the front-rear direction, and the second drive section 17B moves the other end of the movable floor 16 in the width direction in the front-rear direction. As a result, at the tip of the movable floor 16 of the head 4, as shown in FIG. The side can be moved further forward than the one end side.

The movable floor 16 can make the amount of movement at one end of the movable floor 16 in the width direction different from the amount of movement at the other end. Thereby, the direction of the tip of the head 4 on the floor 12 with respect to the boarding gate of the aircraft can be quickly and easily adjusted without changing the position of the tunnel section 3 or the head 4 using the traveling section 7.

Note that the movable floor drive unit 17 may be provided only at one end of the movable floor 16 in the width direction. In this case, at the tip of the movable floor 16 of the head 4, only one end in the width direction can be moved forward or backward relative to the other end. As a result, the amount of movement of the movable floor 16 at the other end in the width direction is fixed to 0 (zero), and the amount of movement of the movable floor 16 at one end of the movable floor 16 in the width direction is different from the amount of movement at the other end. become.

The adjustable floor 18 is, for example, a plate material having a hinge portion 20 (see FIGS. 14 and 15) provided diagonally with respect to the tip of the opening of the head 4, and is an adjustable floor with respect to the movable floor 16 of the head 4. By changing the inclination angle of 18, the levelness of the floor of the aircraft head 4 can be adjusted. The adjustable floor drive unit can drive the adjustable floor 18 to adjust the levelness of the adjustable floor 18. Note that the configuration of the conditioning floor 18 is not limited to the example described above.

As shown in FIG. 2, a bumper portion 19 made of synthetic rubber or synthetic resin is provided on the tip end side of the adjustable floor 18, that is, on the side that comes into contact with the connected aircraft. When the tip of the boarding bridge 1 comes into contact with the aircraft, excessive load is not applied to the aircraft due to the deformation of the bumper portion 19. The bumper portion 19 is provided along the width direction of the floor portion 12 in an area where there is a possibility of contact with an aircraft.

In addition, although the said embodiment demonstrated the case where the adjustment floor 18 was installed, this disclosure is not limited to this example. For example, as shown in FIG. 3, the adjustable floor 18 may not be provided in the floor portion 12, but a fixed floor 15 and a movable floor 16 may be provided. Even in this case, similarly to the case where the adjustable floor 18 is installed, the amount of movement of the movable floor 16 at one end in the width direction can be made different from the amount of movement at the other end.

As shown in FIGS. 7 and 9, vertical load supporting rollers 22 and left and right guide rollers 25 are installed between the main body 35 of the floor 12 and the movable floor 16. Thereby, the movable floor 16 moves smoothly with respect to the main body portion 35 of the floor portion 12.

As shown in FIG. 7 and FIG. 8A or FIG. 8B, frame members 21 are provided on the main body portion 35 of the floor portion 12 along the side surfaces of the head 4 on both sides of the head 4 in the width direction. Upper and lower load supporting rollers 22 are installed on each frame member 21 .

The upper and lower load supporting rollers 22 are rotatably fixed to the frame member 21, and their outer peripheral surfaces can come into contact with a rail-shaped support section 23 provided on the lower surface of the movable floor 16. The cross section of the support portion 23 has a U-shape as shown in FIG. 8A, or an L-shape as shown in FIG. 8B. In the example shown in FIG. 8A, the upper and lower load supporting rollers 22 are provided between two surfaces of the support section 23, and in the example shown in FIG. 8B, the upper and lower load supporting rollers 22 are provided on the upper and lower sides, respectively. It is placed between. The rotation axis of the upper and lower load supporting rollers 22 is parallel to the in-plane direction of the movable floor 16. The vertical load supporting rollers 22 allow the movable floor 16 to move smoothly in the front and rear directions while restricting the movement in the vertical direction.

As shown in FIGS. 9 and 10 and FIG. 11A or 11B, a frame member 24 is provided along the width direction of the head 4 on the lower surface of the fixed bed 15 of the floor portion 12. As shown in FIGS. Left and right guide rollers 25 are installed on the frame member 24.

The left and right guide rollers 25 are rotatably fixed on a support member 26 installed on the frame member 24, and their outer peripheral surfaces can come into contact with a rail portion 27 provided on the lower surface of the movable floor 16. The cross section of the rail portion 27 is U-shaped as shown in FIG. 11A, or a plate-like member as shown in FIG. 11B. In the example shown in FIG. 11A, the left and right guide rollers 25 are provided between two surfaces of the rail portion 27, and in the example shown in FIG. 11B, the left and right guide rollers 25 are provided on both sides of the rail portion 27, respectively. The rotation axis of the left and right guide rollers 25 is perpendicular to the in-plane direction of the movable floor 16. The left and right guide rollers 25 allow the movable floor 16 to move smoothly in the front and rear directions while restricting movement in the width direction, that is, in the left and right directions.

As shown in FIGS. 12 and 13, a support portion 28 is provided on the lower surface of the fixed bed 15 of the floor portion 12. As shown in FIGS. The movable floor drive section 17 is installed on the support section 28 . The movable floor drive unit 17 includes, for example, an electric telescopic cylinder 29. Further, a frame member 30 is provided on the lower surface of the movable floor 16 along the front-rear direction. The telescopic cylinder 29 is connected to the frame member 30 at the distal end side of the rod 29a. When the rod 29a of the telescopic cylinder 29 moves in and out, the movable floor 16 moves in the front-rear direction of the head 4.

A distance detection unit (not shown) that can detect the distance to the aircraft may be provided at a predetermined position on the floor 12. The distance detection section is, for example, a distance measurement sensor such as a photoelectric sensor or a scanning laser sensor.

The boarding bridge 1 includes a control device (not shown). The control device includes, for example, a drive control section and a memory. The drive control section controls the drive of the movable floor drive section 17. Note that the operation of the control device is realized by executing a prerecorded program and using hardware resources such as a CPU.

The drive control section may control the drive of the movable floor drive section 17 according to the position detected by the distance detection section. The drive control section calculates the position and width direction of the boarding gate to which the vehicle is connected based on the distance detected by the distance detection section. The drive control unit adjusts the direction of the movable floor 16 with respect to the boarding gate based on the calculated width direction of the boarding gate of the aircraft.

The movable floor 16 can make the amount of movement at one end of the movable floor 16 different from the amount of movement at the other end in the width direction by the drive control section. Thereby, the direction of the tip of the head 4 on the floor 12 with respect to the boarding gate of the aircraft can be quickly and easily adjusted without changing the position of the tunnel section 3 or the head 4 using the traveling section 7.

As shown in FIG. 26, even if the width direction of the boarding gate 71 of the aircraft 70 and the width direction of the floor section 12 of the head 4 are not parallel, as shown in FIG. The direction of the movable floor 16 can be adjusted so that it is substantially parallel to the width direction of the boarding gate 71. Further, the gap between the boarding gate 71 and the tip of the floor portion 12 of the head 4 can be narrowed without changing the positions of the tunnel portion 3 or the head 4.

As shown in FIGS. 25 and 26, the head 4 has, for example, a structure that allows it to rotate relative to the tunnel portion 3. By combining this with the movement of the movable floor 16 in the longitudinal direction, the movable range in the direction parallel to the width direction of the boarding gate of the aircraft can be increased without changing the position of the tunnel section 3 or the head 4. Can be made larger. For example, as shown in FIG. 25, when the position of the boarding gate 71 of the aircraft 70 and the opening of the head 4 are misaligned, the rotation of the head 4 and the movement of the movable floor 16 in the front and rear direction may cause the tunnel portion 3 or As shown in FIG. 27, the amount of positional deviation between the boarding gate 71 of the aircraft 70 and the opening of the head 4 can be adjusted without changing the position of the head 4.

As shown in FIG. 30, the head 4 may have, for example, a configuration in which the movable bed 16 is movable relative to the fixed bed 15 in parallel to the width direction of the head 4. As a result, the movable floor 16 moves parallel to the width direction of the head 4 while the fixed floor 15 remains fixed. It becomes possible to move the aircraft in a direction parallel to the width direction of the boarding gate of the aircraft without changing the position of the aircraft.

In the example shown in FIG. 30, walls 41 and 42 are installed between the movable floor 16 and the fixed floor 15. The wall portions 41 are provided at both ends of the movable floor 16, and the wall portions 42 are provided at both ends of the fixed bed 15. Thereby, even when the movable floor 16 moves in the width direction, the inside of the head 4 can be made into a closed space.
Further, the configuration in which the movable bed 16 moves in the width direction of the head 4 with respect to the fixed bed 15 is not limited to the example shown in FIG. 30, but may be the example shown in FIG. 31. In this case, the interior of the head 4 is made into a closed space by providing protrusions 43 protruding outward in the width direction at both ends of the fixed bed 15.

As shown in FIG. 1, the cover part 13 has a space inside which passengers can pass, and one end side is connected to the tip of the tip tunnel 3b. The cover part 13 includes, for example, a plate-shaped wall part and a roof part, and is fixed to the floor part 12 of the head 4.

The canopy section 14 has a portal shape and can come into contact with the outer surface of the aircraft fuselage. The size of the opening of the canopy section 14 is larger than the boarding gate of the aircraft, and the floor section 12 of the head 4 and the walls and ceiling of the canopy section 14 can surround the boarding gate of the aircraft on all sides.

The canopy portion 14 is, for example, a bellows-shaped hood. The canopy section 14 can expand and contract in the front and rear directions as the distal end side of the canopy section 14 moves. The canopy section 14 has a cloth section 31 and a plurality of canopy frame sections 32, as shown in FIGS. 16 to 18. The cloth portion 31 is, for example, a sheet made of synthetic fiber. Each of the canopy frames 32 is a gate-shaped member, and is made of, for example, spring steel. A plurality of canopy frame sections 32 are installed along the passage of the canopy section 14. The lower end of the canopy section 14 is connected to a movable floor 16.

Unlike this embodiment, as shown in FIG. 33, when the lower end of the canopy section 14 is not connected to the movable floor 16 but is connected to the fixed floor 15, the movable floor 16 approaches the aircraft 70 side, and When the canopy section 14 moves to cover the aircraft 70 side, a gap is formed below the canopy section 14.

On the other hand, as shown in FIGS. 16 to 20, the canopy section 14 according to the present embodiment has its entire lower end connected to the movable floor 16. As a result, as shown in FIGS. 17 and 19, the movable floor 16 is located on the tunnel portion 3 side, and as shown in FIGS. 18 and 20, the movable floor 16 is located on the aircraft 70 side. By moving to the present state, the canopy section 14 also moves accordingly. Since the canopy part 14 moves with the movement of the movable floor 16, as shown in FIG. 32, a gap is less likely to be formed below the canopy part 14, and the intrusion of wind and rain can be suppressed.

Note that the canopy section 14 according to the present embodiment is not limited to an example in which the entire lower end portion of the canopy section 14 is connected to the movable floor 16, and as shown in FIGS. 21 to 24, the lower end portion is One end may be connected to the movable floor 16, and the other end of the lower end in the longitudinal direction may be connected to the fixed floor 15. In this case, the canopy frame 32 provided between the movable floor 16 and the fixed floor 15 may be connected to the movable floor 16 via the slide block 33. The slide block 33 is movable in the front-back direction along a rail provided on the movable floor 16.

As a result, as shown in FIGS. 21 and 23, the movable floor 16 is located on the tunnel portion 3 side, as shown in FIGS. 22 and 24, the movable floor 16 is located on the aircraft 70 side. By moving to the present state, the canopy section 14 also moves accordingly. Thereby, since the canopy section 14 moves with the movement of the movable floor 16, a gap is less likely to be formed below the canopy section 14, and the intrusion of wind and rain can be suppressed.

Next, the operation of the movable floor 16 of the boarding bridge 1 according to this embodiment will be explained.
First, as shown in FIG. 25, the tunnel portion 3 and the head 4 are brought close to the boarding gate 71 of the aircraft 70. At this time, as shown in FIG. 25, the boarding gate 71 of the aircraft 70 and the opening of the head 4 may be misaligned.

Then, as shown in FIG. 26, the head 4 is turned to direct the opening of the head 4 toward the boarding gate 71. Next, as shown in FIG. 27, only the movable floor 16 is moved without moving the head 4 or the tunnel portion 3 forward. For example, the right side of the movable floor 16 in the width direction is moved forward according to the gap formed between the boarding gate 71 and the opening.

As a result, by simply moving the movable floor 16 forward without moving the head 4 or the tunnel section 3 forward, the width direction of the tip of the floor section 12 can be made parallel to the width direction of the boarding gate 71. A movable floor 16 can be placed in the area.

In the above example, not only the right side of the movable floor 16 in the width direction but also both sides of the movable floor 16 in the width direction are moved so that the amount of movement on the right side of the movable floor 16 in the width direction is larger than the left side in the width direction. It's okay. Thereby, the tip of the floor portion 12 of the head 4 can be brought closer to the aircraft 70 side without moving the head 4.

Furthermore, by driving the adjustable floor 18 after the movable floor 16 approaches the boarding gate 71 side of the aircraft 70, the inclination angle of the adjustable floor 18 changes, and the difference between the inclination of the boarding gate 71 and the inclination of the head 4 is changed. can be made smaller.

When the lower end of the canopy section 14 is connected to the movable floor 16, by moving the movable floor 16 forward, the lower end of the canopy section 14 moves together with the movable floor 16 toward the aircraft 70. This makes it difficult for a gap to be formed below the canopy portion 14, thereby suppressing the intrusion of wind and rain.

Further, as shown in FIGS. 28 and 29, a rotating shaft 51 parallel to the vertical direction may be provided at the connecting portion between the tunnel portion 3 and the head 4, so that the head 4 can be rotated around the rotating shaft 51. . As a result, the length L in FIG. 28 becomes longer, and even if the turning angle of the head 4 is small, a larger amount of horizontal movement can be obtained at the tip of the floor portion 12 of the head 4 in the width direction of the boarding gate. Therefore, the range in which the direction of the head 4 can be moved can be increased without moving the tunnel portion 3. 28 shows an example in which the rotating shaft 51 is provided near the side surface of the tunnel portion 3, and FIG. 29 shows an example in which the rotating shaft 51 is provided on the central axis of the tunnel portion 3.

As described above, according to the present embodiment, since the amount of movement of the movable floor 16 at one end in the width direction can be made different from the amount of movement at the other end, the tip of the floor section 12 of the head 4 can be moved in the width direction of the boarding gate. It can be arranged parallel to the As a result, when the head 4 is installed with the direction of the head 4 facing the boarding gate so that the width direction of the boarding gate and the width direction of the opening of the head 4 are parallel, the amount of movement of the tunnel portion 3 and the head 4 can be reduced. Furthermore, the gap between the boarding gate and the tip of the head 4 can be narrowed without changing the orientation of the head 4.

In the embodiment described above, the movable leg 5 may be provided with a stabilizer 36, as shown in FIGS. 34 and 35. The stabilizer 36 is a vertically movable leg, and is, for example, electric. When the movable leg 5 moves, as shown in FIG. 34, the stabilizer 36 is positioned on the upper side so as not to impede the running of the boarding bridge 1, and when the movable leg 5 is fixed, as shown in FIG. , the stabilizer 36 is located on the lower side and is grounded.

When the traveling section 7 of the boarding bridge 1 is made of two wheels, the tunnel section 3 and the head 4 are likely to swing left and right due to the influence of wind and the like. Therefore, it is difficult to bring the head 4 close to the boarding gate 71 of the aircraft 70, such as during strong winds. Therefore, in the traveling section 7, it was necessary to use four wheels 9 (two sets of two wheels) or to provide an auxiliary wheel. However, these structures have problems in that the movable legs 5 of the boarding bridge 1 become larger and the cost also increases.

When the stabilizer 36 is provided, the stabilizer 36 can suppress shaking, and the structure of the movable leg 5 can be relatively simplified. On the other hand, if the stabilizer 36 is grounded immediately before touchdown so as not to sway under the influence of wind or the like, the running section 7 cannot be driven, and therefore the boarding bridge 1 cannot be connected to the aircraft 70 by the running section 7. On the other hand, in the embodiment described above, when the movable floor 16 is driven, the tip of the movable floor 16 moves in the front and rear directions with respect to the fixed floor 15. There is no need to use section 7.

That is, when the stabilizer 36 is provided on the movable leg 5, first, as shown in FIG. 36, the entire boarding bridge 1 is brought close to the front of the aircraft 70 by the running portion 7 of the movable leg 5. Then, for example, at the position shown in FIG. 36, the stabilizer 36 is grounded to prevent the boarding bridge 1 from rolling. Next, the positional deviation between the boarding gate 71 of the aircraft 70 and the head 4 is detected visually or by a detection device. Thereafter, as shown in FIG. 37, by driving the movable floor 16, the boarding gate 71 of the aircraft 70 and the tip of the movable floor 16 in the head 4 are aligned, and the movable floor 16 is moved to the boarding gate 71 of the aircraft 70. Bring them close to complete the connection work.

Therefore, the boarding bridge 1 can be connected to the aircraft 70 while the movable legs 5 are kept fixed by the stabilizers 36. In this embodiment, since shaking can be suppressed by providing the stabilizer 36, the number of wheels 9 of the traveling section 7 can be two, and the structure can be simplified.

Further, in the embodiment described above, the movable floor 16 in the floor portion 12 of the head 4 is movable in the front and rear directions with respect to the fixed floor 15, and at the tip of the movable floor 16, both sides in the width direction are simultaneously moved forward or backward. Although an example has been described in which one end in the width direction is moved forward than the other end, the present invention is not limited to this example.

For example, as shown in FIG. 38(A), the head 4 may have a rear structure section 4A in which a fixed floor 15 is provided and a front structure section 4B in which a movable floor 16 is provided. The front structure section 4B is movable in the front-back direction with respect to the rear structure section 4A. In this case as well, at the tip of the movable floor 16 provided in the front structure part 4B, both sides in the width direction may be moved forward or backward at the same time (FIG. 38(B)), or one end in the width direction may be moved further than the other end. It can be moved forward (FIG. 38(C)).

Further, as shown in FIG. 39(A), the head 4 may not be fixed to the tunnel portion 3, but may have a configuration in which the entire head 4 is movable in the front and back direction with respect to the tunnel portion 3. In this case, the tunnel section 3 is provided with a fixed bed 15', and the head 4 is provided with a movable bed 16. Thereby, the movable floor 16 of the head 4 is movable in the front and back direction with respect to the fixed floor 15' of the tunnel portion 3. By moving the entire head 4 in the front-rear direction with respect to the tunnel portion 3, both sides in the width direction can be moved forward or backward at the same time at the tip of the movable floor 16 provided in the head 4 (FIG. 39(B)). , one end in the width direction can be moved further forward than the other end (FIG. 39(C)). In this case, the drive unit that drives the movable floor 16 is the drive unit that drives the entire head 4.
