The boarding bridge 1 according to an embodiment of the present invention forms a passenger passage between an airport terminal building and an aircraft, connects the terminal building and the aircraft, and allows passengers to get on and off directly. .
The boarding bridge 1 moves between, for example, a standby position for preparation for connection before arrival of the aircraft and a connection position when connected to the aircraft.

  As shown in FIG. 1, the boarding bridge 1 is connected to a rotander 2 fixed to a terminal building or a fixed bridge leading to the terminal building, and is connected to the rotander 2 so as to be rotatable in the horizontal direction and the vertical direction. The proximal end tunnel 3a and the distal end side (aircraft side) of the proximal end tunnel 3a are fitted on the outer side of the proximal end tunnel 3a in a nested manner, and are fixed to the distal end portion of the movable end tunnel 3b and the distal end tunnel 3b. A head 4 and the like.

  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 columns 11 attached to both side surfaces of the front end tunnel 3b and extending in the vertical direction. A fixed leg 6 is fixed to the ground below the rotander 2. The boarding bridge 1 is supported by a movable leg 5 and a fixed leg 6. The proximal end tunnel 3 a and the distal end tunnel 3 b constitute a passage portion 3, and the passage portion 3 and the head 4 are movable by a movable leg 5. The rotander 2 may be supported by a terminal building, and the fixed leg 6 may not be installed at the lower part.

  The cross-sectional area of the hollow portion of the front end tunnel 3b is larger than the cross-sectional area of the base end tunnel 3a. The distal end tunnel 3b moves along the outer peripheral surface of the proximal end tunnel 3a. The total length of the passage portion 3 is extended by moving the tip tunnel 3b to the parking side of the aircraft, and the total length of the passage portion 3 is contracted by moving the tip tunnel 3b to the rotander 2 side. The tunnel portion of the present invention is not limited to the combination of the two tunnel portions of the proximal end tunnel 3a and the distal end tunnel 3b, and three or more tunnel portions are connected to each other and have two or more steps of expansion and contraction mechanisms. Good.

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

  The distal end tunnel 3b is moved in the longitudinal direction and the left-right direction of the proximal end tunnel 3a and the distal end tunnel 3b when the traveling portion 7 provided on the movable leg 5 is driven and the movable leg 5 is moved.

  The proximal end tunnel 3 a is rotatable around a rotation axis that is provided in the rotander 2 and is parallel to the horizontal direction. The movable leg 5 can be adjusted in the height direction of the distal end tunnel 3b by the 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 by rotating up and down around the rotation axis. The

  In this way, the boarding bridge 1 expands and contracts, or rotates in the horizontal direction and the vertical direction around the rotation axis provided in the rotander 2. Proper connection to the aircraft.

  The head 4 has an opening formed on the front end side, and the front end side is connected to an entrance / exit of the aircraft. Inside the head 4, there is provided an operation panel 9 for starting the driving of the traveling unit 7 of the boarding bridge 1 and operating the traveling direction (steering angle) of the wheels 19 of the traveling unit 7.

  In the rotander 2, the base end tunnel 3 a, the front end tunnel 3 b, and the head 4 of the boarding bridge 1, a passage through which passengers pass is installed from the rotander 2 toward the head 4.

  As shown in FIG. 3, a support beam 12 extending horizontally is fixedly attached to the lower ends of the pair of support columns 11 so as to connect them. The traveling unit 7 synchronizes the traveling directions of the two sets of wheel units 8 attached to the lower part of the support beam 12 at the extended position of the support column 11 and the two sets of wheel units 8, that is, the turning angle (steering angle). A turning synchronizer 13 is provided.

The traveling unit 7 includes a swivel unit 14 that is rotatably supported around an axis parallel to the vertical direction, a connection unit 15 fixedly attached to a lower portion of the swivel unit 14, and a pin 17 with respect to the connection unit 15. The shaft holding part 16 attached by is provided. The traveling unit 7 includes an axle 18 supported by the shaft holding unit 16, two rubber wheels 19 attached to both ends of the axle 18 via bearings (not shown), and wheels And a drive unit 20 that rotationally drives 19. For example, the drive unit 20 is attached to the shaft holding unit 16 and includes a travel motor with a speed reducer and a transmission mechanism such as a chain or a belt.
In addition, although this embodiment demonstrates the case where the traveling part 7 is provided with two sets of wheel parts 8, and each wheel part 8 has the two wheels 19, this invention is not limited to this example. For example, only one set of wheel portions 8 having two wheels 19 may be installed on the movable leg 5.

  The rotation operation of the turning unit 14 is transmitted to the shaft holding unit 16 via the connection unit 15 to rotate the shaft holding unit 16 around the axis. Thereby, since the axle shaft 18 rotates around the axis, the traveling direction of the wheels 19 changes.

As shown in FIGS. 2 to 4, the turning synchronizer 13 is attached to the lower part of the support beam 12.
The swivel synchronizer 13 includes a swivel sprocket 21 that is fixedly attached to the outer periphery of each swivel unit 14 so as to have the same axis center, an intermediate sprocket 22 installed at a substantially intermediate position between the two swivel sprockets 21, A turning synchronization chain 23 for winding the turning sprocket 21 and the intermediate sprocket 22 and a plurality of guide sprockets 24 for guiding the turning synchronization chain 23 are provided.

  The turning synchronization chain 23 is wound around a turning sprocket 21 fixedly attached to the turning portion 14 of each wheel portion 8. Thereby, the turning part 14 of each wheel part 8 is integrally connected via the turning synchronization chain 23. Since the turning sprocket 21 attached to the turning portion 14 rotates by the amount of movement of the turning synchronization chain 23, the turning sprocket 21 is rotated by the same amount as shown in FIG. .

  The drive unit 20 is connected to only one wheel 19 of the pair of wheels 19. One wheel 19 connected to the transmission mechanism of the drive unit 20 functions as a drive wheel 19A, and the other wheel 19 functions as a driven wheel 19B. The traveling speed of the traveling unit 7 can be adjusted by changing the rotational speed of the drive wheels 19A.

  The traveling direction of the traveling unit 7 and the turning angle (steering angle) of the traveling unit 7 with respect to the length direction of the tip tunnel 3b of the wheel unit 8 are the difference in rotational speed between the two drive wheels 19A and 2 Adjustment is possible by changing the direction of rotation (normal rotation or reverse rotation) of each drive wheel 19A.

For example, the rotation speed and the rotation direction of the drive wheel 19A are adjusted in accordance with each of the traveling unit 7 when performing a straight movement, a turning movement (stationary movement), or a curve traveling.
When the traveling unit 7 is caused to linearly move, the two drive wheels 19A are rotated in the same direction at the same speed. In FIG. 2, when two drive wheels 19A are driven in the upward direction in FIG. 2, the left traveling unit 7 tries to turn clockwise by the left driving wheel 19A, and the right traveling unit 7 The drive wheel 19A attempts to turn counterclockwise. However, since the turning synchronous chain 23 prevents the turning, the two left and right traveling units 7 travel while maintaining the same direction without turning. In the forward movement and the reverse movement, the rotation direction of the drive wheel 19A is opposite.

  When the traveling unit 7 is turned, the rotation direction of the two drive wheels 19A is reversed. In FIG. 2, when the left driving wheel 19A is driven downward in the drawing of FIG. 2 and the right driving wheel 19A is driven upward in the drawing of FIG. Each of the traveling parts 7 tries to turn counterclockwise. Since both traveling parts 7 are connected by the turning synchronization chain 23, both traveling parts 7 make a counterclockwise turning motion on the spot. As a result, the two traveling units 7 move to positions as shown in FIG. 4, for example. On the other hand, in FIG. 2, when the traveling unit 7 is caused to make a clockwise turning motion, the left driving wheel 19A is driven in the upward direction in FIG. 2, and the right driving wheel 19A is moved to FIG. Drive down the paper.

When the traveling unit 7 is traveling in a curve, the rotational speed is varied while rotating the two drive wheels 19A in the same direction. For example, in FIG. 2, in the case where the two drive wheels 19A are driven in the upward direction in FIG. 2, when the travel speed of the left drive wheel 19A is made smaller than the travel speed of the right drive wheel 19A, The traveling unit 7 makes a large left curve while moving forward, centering on the left side of the extension line connecting the two axles 18. In FIG. 2, when the two drive wheels 19A are driven in the upward direction in FIG. 2, when the travel speed of the right drive wheel 19A is made smaller than the travel speed of the left drive wheel 19A, the left and right travel sections 7 makes a right curve movement while moving forward, centering on the right side on the extension line connecting the two axles 18.
In FIG. 2, when the two drive wheels 19A are driven in the downward direction in FIG. 2, the vehicle moves backward while performing a curve motion.

Conventionally, in a boarding bridge provided with a pair of travel parts, a drive device for driving a swing synchronization chain or a gear mechanism that connects the travel parts is provided, and the drive device moves the swing synchronization chain or rotates the gear mechanism. In general, the traveling unit 7 is turned.
On the other hand, according to the traveling unit 7 of the present embodiment, a driving device that drives the turning synchronization chain 23 is provided, and the traveling unit 7 is not turned by moving the turning synchronization chain 23 by the driving device. The traveling direction of the traveling unit 7 and the traveling unit are changed by changing the difference between the rotational speeds of the two driving wheels 19A and the rotational directions (forward or reverse) of the two driving wheels 19A. 7 turning angle (steering angle) is adjusted. That is, there is no drive device for turning the travel unit 7, and the travel unit 7 can travel freely by the drive unit 20 that drives the drive wheels 19 </ b> A.

  As shown in FIGS. 1 and 5 to 8, a swiveling floor 25 is installed at the tip of the head 4, and the swiveling floor 25 forms a part of the getting-on / off passage between the head 4 and the entrance / exit 92 of the aircraft 90.

A handrail 28 is installed at the side end of the floorboard body 27.

  The support frame 26 is supported under the floor of the head 4 so as to be able to turn on a plane parallel to the floor surface of the head 4 with the rotation shaft 26A as a fulcrum (rotation center).

  The first turning drive mechanism 29 turns the support frame 26 with respect to the head 4. As shown in FIG. 7, the first turning drive mechanism 29 turns when the turning floor 25 is stored in a position retracted from the front end side of the head 4 and when it is connected to the aircraft 90 as shown in FIG. It is swung between the position where the floor 25 is arranged. As a result, the support frame 26 moves between the retracted position retracted from the front end side of the head 4 and the passage forming position where the entrance / exit passage is formed between the entrance / exit 92 and the head 4.

  The first turning drive mechanism 29 uses, for example, a hydraulically driven cylinder 30 as a drive source. The cylinder 30 has a piston rod 31 that expands and contracts by hydraulic pressure. The cylinder 30 has one end connected to the head 4 and the other end connected to the support frame 26 via a piston rod 31 by pin coupling. Thereby, the support frame 26 is disposed at the storage position with the piston rod 31 contracted, and is disposed at the passage formation position with the piston rod 31 extended. The first turning drive mechanism 29 can be turned by a switch operation or the like to turn the turning bed 25 to a desired position. In the state of use arranged when connected to the aircraft 90, the first turning drive mechanism 29 is, as shown in FIG. 9B, the support frame 26 within an angle range smaller than the movement of the support frame 26 described above. Can be swung, and the direction of the support frame 26 can be finely adjusted.

  The support frame 26 supports a floor board body 27. The floor board body 27 pivots on a plane parallel to the floor surface of the floor board body 27 with respect to the support frame 26 with the rotation shaft 27A as a fulcrum (rotation center). Is supported. In the state of use arranged when connected to the aircraft 90, the floorboard body 27 can be turned in a relatively small angle range, and the direction of the floorboard body 27 can be finely adjusted. The floor plate body 27 may be manually swiveled around the rotation axis with respect to the support frame 26, or may be mechanically swiveled with a second swivel drive mechanism (not shown).

  The second turning drive mechanism turns the floorboard body 27 with respect to the support frame 26. The second turning drive mechanism uses, for example, a hydraulically driven cylinder as a drive source. The cylinder has a piston rod that expands and contracts by hydraulic pressure. One end of the cylinder is connected to the support frame 26 by pin coupling, and the other end is connected to the floor plate body 27 via a piston rod.

The support frame 26 includes, for example, an arm part 32, a link mechanism 33, a cylinder 34, a bearing part 35, and the like.
The arm part 32 is a long member that is long in one direction. A rotary shaft 26A connected to the head 4 is formed at one end, and a link mechanism 33 and a cylinder 34 are connected to the other end. The arm portion 32 is installed on the lower surface of the head 4 and is installed to be inclined downward from the connection side with the head 4 toward the tip side.

  The rotation shaft 26 </ b> A is provided in a direction perpendicular to the floor surface of the head 4. The arm portion 32 rotates with respect to the head 4 by rotating around the rotation shaft 26A. The arm part 32 is mechanically turned by the first turning drive mechanism 29 that moves the arm part 32.

  The link mechanism 33 has one end connected to the arm portion 32 and the other end connected to the bearing portion 35. The link mechanism 33 has a configuration capable of adjusting the height of the bearing portion 35 relative to the arm portion 32, that is, the floorboard body 27. The link mechanism 33 includes a drive link 33A connected to the cylinder 34 and a driven link 33B that operates in accordance with the movement of the drive link 33A. The cylinder 34 is a hydraulic cylinder, for example. The link mechanism 33 is operated by the cylinder 34, and the bearing portion 35 is mechanically moved downward or upward. When the bearing portion 35 moves upward, the floor surface of the floor plate body 27 and the floor surface of the head 4 become the same, and when the bearing portion 35 moves downward, the floor plate body 27 moves below the floor of the head 4. Go down. When the boarding bridge 1 is connected to the aircraft 90, the entire head 4 is moved up and down by the movable legs 5 so that the upper surface of the floor board body 27 and the floor surface of the entrance / exit 92 of the aircraft 90 coincide with each other. Surface height is adjusted. At this time, the floor surface height of the floorboard body 27 may be finely adjusted by operating the link mechanism 33.

  The bearing portion 35 is a cylindrical member and is connected to the link mechanism 33 on the side surface. The bearing portion 35 is provided such that the axial direction is perpendicular to the floor surface of the floor plate body 27. A through hole 35 </ b> A is formed in the bearing portion 35 along the axial direction, and the rotating shaft 27 </ b> A of the floor board body 27 is inserted therein. As a result, the floor plate main body 27 can pivot on the bearing portion 35 and pivots relative to the support frame 26. The bearing portion 35 is provided with a brake portion 36, and the brake portion 36 can fix the turning of the floor board body 27. When the floor board body 27 is turned, the brake part 36 is released.

  As shown in FIG. 10, the boarding bridge 1 includes a first detection unit 41 that detects the turning angle of the head 4 with respect to the distal end tunnel 3 b, and a second detection unit 42 that detects the turning angle of the support frame 26 with respect to the head 4. A third detector 43 that detects the turning angle of the floor plate body 27 with respect to the support frame 26 is installed. The first detection unit 41, the second detection unit 42, and the third detection unit 43 are, for example, rotation sensors, and the first detection unit 41 is provided, for example, on a rotation shaft (not shown) of the head 4. The second detection unit 42 is provided on the rotation shaft 26 </ b> A of the support frame 26, and the third detection unit 43 is provided on the rotation shaft 27 </ b> A of the floor board body 27. The detection results of the first detection unit 41, the second detection unit 42, and the third detection unit 43 are transmitted to the angle calculation unit 51 of the control device 50. In the present embodiment, the first detection unit 41, the second detection unit 42, and the third detection unit 43 constitute a detection unit according to the present invention that detects a turning angle of the swiveling floor 25 with respect to the passage unit 3.

  The boarding bridge 1 is provided with the control apparatus 50 which controls operation | movement of the driving | running | working part 7 etc., as shown in FIG. The control device 50 includes, for example, an angle calculation unit 51, a wheel control unit 52, a memory 53, and the like. The operation of the control device 50 is realized by a hardware resource such as a CPU by executing a program recorded in the memory 53 in advance.

Based on the detection results detected by the first detection unit 41, the second detection unit 42, and the third detection unit 43, the angle calculation unit 51 determines the angle α formed by the installation direction of the floorboard body 27 and the axis of the tip tunnel 3b. Is calculated. The installation direction of the floorboard body 27 refers to the direction of the longitudinal axis of the floorboard body 27. As shown in FIG. 11, the turning angle theta ₁ of the head 4 with respect to the first detector 41 in the tip tunnel 3b is detected, the turning angle theta ₂ of the second detection unit 42 the support frame 26 with respect to the head 4, is detected, the Since the rotation angle θ ₃ of the floor board body 27 with respect to the support frame 26 is detected by the 3 detector 43, the angle α formed by the installation direction of the floor board body 27 and the axis of the tip tunnel 3 b is the detected rotation angle. It is obtained by adding θ ₁ , θ ₂ , and θ ₃ .

The operation panel 9 receives the operation of the operator and transmits an operation signal to the wheel control unit 52. The operation panel 9 is provided with interfaces such as buttons and joysticks for starting and stopping movement of the boarding bridge and the traveling direction of the wheels 19. Further, the operation panel 9 is provided with a button or the like that allows input related to automatic wheel direction setting. When the input related to automatic wheel direction setting is performed before the head 4 approaches the aircraft 90, the wheel control unit 52 is provided. Thus, the direction of the wheel portion 8 is automatically set.
Two or more operation panels 9 may be provided instead of only one. For example, when two operation panels 9 are installed, the operation panel 9 includes two main operation panels and sub operation panels. Further, the sub operation panel can be made portable instead of fixed.

  The wheel control unit 52 determines the turning angle of the wheel unit 8 with respect to the axis of the tip tunnel 3b based on the angle α between the installation direction of the floorboard body 27 calculated by the angle calculation unit 51 and the longitudinal axis of the tip tunnel 3b. To change. The wheel control unit 52 generates a control signal related to the direction of the wheel unit 8 with respect to the axis of the front end tunnel 3 b, and transmits the generated control signal to the wheel unit 8. The wheel control unit 52, for example, the angle α formed by the installation direction of the floorboard body 27 calculated by the angle calculation unit 51 and the longitudinal axis of the tip tunnel 3b, the traveling direction of the wheel unit 8, and the length of the tip tunnel 3b. The wheel portion 8 is controlled so that the angle β (see FIG. 12) formed with the direction axis coincides.

  The wheel unit 8 adjusts the turning angle of the wheel 19 based on the received control signal. Thus, the traveling direction of the wheel 19 is changed, and the angle α formed by the installation direction of the floorboard body 27 calculated by the angle calculating unit 51 and the longitudinal axis of the tip tunnel 3b, the traveling direction of the wheel 19 and the tip tunnel. The angle β formed with the longitudinal axis 3b coincides. Thereby, the longitudinal direction of the floor board main body 27 and the traveling direction of the wheel 19 become parallel.

  If the longitudinal direction of the floorboard main body 27 and the traveling direction of the wheel 19 do not have to be parallel by the wheel direction automatic setting, the angle β formed by the traveling direction of the wheel 19 and the longitudinal axis of the tip tunnel 3b is The angle α between the installation direction of the floorboard body 27 calculated by the angle calculation unit 51 and the longitudinal axis of the tip tunnel 3b may not be matched.

Next, an operation when the boarding bridge 1 is connected to the aircraft 90 will be described with reference to FIGS.
As shown in FIG. 14, the boarding bridge 1 is stopped at the standby position. At this time, the support frame 26 is swung with respect to the head 4, and the swivel floor 25 is disposed at the passage formation position (step S1).

  Thereafter, the boarding bridge 1 is operated by an operator, the wheels 19 are driven, and the wheel 19 is moved from the standby position, and the head 4 is stopped before the connection position with the aircraft 90 as shown in FIG. (Step S2). Then, as shown in FIGS. 9A and 16, the direction of the head 4 is operated, and the turning angle of the head 4 is adjusted so that the opening of the head 4 faces the entrance / exit 92 of the aircraft 90 (step) S3).

  With the opening of the head 4 facing the entrance / exit 92 of the aircraft 90, the operator makes fine adjustments while turning the support frame 26 relatively small with respect to the head 4 to adjust the turning angle of the floor plate body 27. As shown in FIGS. 9B and 16, the floorboard body 27 is directed toward the entrance 92 (step S4). At this time, the longitudinal direction of the floor board main body 27 and the longitudinal direction of the staircase 91 for getting on and off are made parallel, and the longitudinal axis of the main board 27 and the longitudinal axis of the staircase 91 for getting on and off coincide with each other. It is desirable that the floor board body 27 is adjusted.

  When an input regarding wheel direction automatic setting is performed at a position where the operator stops before the aircraft 90 before instructing the approaching operation of the boarding bridge 1 (step S5), the first detection unit 41 in the wheel control unit 52 is performed. The turning angle of the head 4 with respect to the tip tunnel 3b detected by the second detection unit 42 is acquired, the turning angle of the support frame 26 with respect to the head 4 detected by the second detection unit 42 is acquired, and the support frame detected by the third detection unit 43 The turning angle of the floorboard body 27 with respect to 26 is acquired (step S6).

  Moreover, the angle of the floor board main body 27 with respect to the tip tunnel 3b is calculated based on each acquired turning angle (step S7). Then, based on the calculated angle of the floor plate body 27 with respect to the tip tunnel 3b, the turning angle of the wheel 19 with respect to the longitudinal direction of the tip tunnel 3b is adjusted (step S8). Thus, when the operator makes an input related to automatic wheel direction setting, the traveling direction of the wheel 19 is automatically set.

  After the adjustment of the orientation of the swivel floor 25 is completed, the boarding bridge 1 is further moved closer to the aircraft 90 by the operation of the operator (step S9), and the floor board body 27 is moved on and off the aircraft 90 as shown in FIG. Connected to the mouth 92 (step S10). First, the operator makes the longitudinal direction of the floor board main body 27 and the longitudinal direction of the staircase for getting on / off 91 parallel to each other, so that the longitudinal axis of the floor board main body 27 and the longitudinal axis of the staircase for getting on / off 91 substantially coincide with each other. Since the support frame 26 and the floor board main body 27 are adjusted, after the turning angle of the wheel 19 is changed by the wheel direction automatic setting, the floor board main body 27 can be moved straightly by moving the wheel 19 straight. 92 can be connected.

  In addition, if the load balance in the movable leg 5 is biased, the deformation amount of each wheel 19 is different, or the rotation speed of the motor is different depending on the load difference of the wheel 19. Therefore, even if the direction of the wheel 19 is changed so as to be parallel to the longitudinal direction of the floor board body 27, the head 4 rotates around the rotander 2 as shown in FIG. The floor board body 27 may not be able to connect to the target entrance / exit 92 of the aircraft 90.

  Therefore, instead of changing the turning angle of the wheel 19 so that the longitudinal direction of the floorboard body 27 and the traveling direction of the wheel 19 are parallel, the traveling of the wheel 19 so that the floorboard body 27 goes straight when the wheel 19 is driven. The direction may be set by inclining in advance. For example, instead of setting the turning angle of the wheel 19 in the direction indicated by the solid line arrow in FIG. 12, the turning angle of the wheel 19 may be set in the direction indicated by the line arrow in FIG. Good. Or you may set with the difference in the rotation speed of the wheel 19 so that the floor board main body 27 may go straight when the wheel 19 drives. Thereby, when the wheel 19 is driven, the floor board main body 27 goes straight, and the floor board main body 27 can be connected to the entrance / exit 92 of the aircraft 90 targeted.

  As described above, according to the present embodiment, when the head 4 of the boarding bridge 1 approaches the aircraft 90 by the operation of the operator, the direction of the floorboard body 27 is detected, and the turning angle of the wheel 19 is calculated based on the detection result. Thus, the traveling direction of the wheel 19 is automatically adjusted. Therefore, when the operator approaches the head 4 of the boarding bridge 1 to the aircraft 90, the operator can easily move the swivel floor 25 to the aircraft without performing a fine adjustment operation to avoid interference with the handrail 93 of the boarding stairs 91. It is possible to connect to 90 entrances / exits 92. That is, the operator is operating the boarding bridge 1 inside the head 4 and cannot see the direction of the wheels, and the position of the head 4 and the position of the wheels 19 are distant from each other. When it is difficult to adjust the direction of the wheel during operation, the turning floor 25 of the boarding bridge 1 can be appropriately and easily connected to the entrance / exit 92 of the aircraft 90 by the automatic direction setting of the wheel 19.

  The floor board body 27 is supported by the head 4 by a support frame 26, and the support frame 26 is pivotally connected at both ends of the head 4 side and the floor board body 27 side. Therefore, unlike the case where the floor plate body 27 is supported by the head 4 and can be turned only at the connection portion with the head 4, the head 4 can be turned without maintaining the installation direction of the head 4. In addition, the floor board body 27 can be aligned with the entrance / exit 92 of the aircraft 90 by adjusting the angle between the support frame 26 and the floor board body 27. In addition, since the head 4 is not turned when the angle of the floorboard body 27 is adjusted, the entrance / exit 92 of the aircraft 90 and the opening of the head 4 can be kept parallel. Therefore, even when the canopy provided in the head 4 is connected to the aircraft 90, a gap is hardly generated between the aircraft 90 and the canopy.

  In the above-described embodiment, the swivel floor 25 in which the floor board body 27 is supported by the support frame 26 has been described. However, the floor board body 27 is not necessarily supported by the swivel floor 25 to which the automatic setting of the traveling direction of the wheels 19 can be applied. The configuration supported by the frame 26 is not limited. That is, as shown in FIGS. 19 and 20, the present invention can also be applied to a swivel floor 25 in which the floor plate body 27 is supported by the head 4 and can swivel only at the connection portion with the head 4. In this case, since it is necessary to rotate the head 4 and align the floor plate body 27 with the entrance / exit 92 of the aircraft 90, as shown in FIG. 20, the entrance / exit 92 of the aircraft 90 and the opening of the head 4 Cannot be kept parallel. Therefore, as shown in FIG. 21, when the floor board body 27 is connected to the entrance / exit 92 of the aircraft 90 and the canopy 37 provided in the head 4 is connected to the aircraft 90, there is a gap between the aircraft 90 and the canopy 37. May occur.

  However, as in the embodiment described above, when the head 4 of the boarding bridge 1 approaches the aircraft 90, the turning angle of the head 4 with respect to the tip tunnel 3b and the turning angle of the floor plate body 27 with respect to the head 4 are detected, Based on the detection result, the direction of the floor board body 27 with respect to the head 4 is calculated. The passage of the swivel floor 25 is detected by a first detector 41 that detects the turning angle of the head 4 with respect to the tip tunnel 3b and a fourth detector (not shown) that detects the turning angle of the floor plate body 27 with respect to the head 4. The detection part which detects the turning angle with respect to the part 3 according to the present invention is configured.

  The angle α formed by the installation direction of the floorboard body 27 calculated by the angle calculation unit 51 and the longitudinal axis of the front end tunnel 3b, and the travel direction of the wheel unit 8 and the longitudinal axis of the front end tunnel 3b. The turning angle of the wheel 19 can be automatically adjusted by controlling the wheel portion 8 so that the angle β (see FIG. 12) matches. As a result, when the operator approaches the head 4 of the boarding bridge 1 to the aircraft 90, the operator simply moves the floorboard body 27 without performing a fine adjustment operation to avoid interference with the handrail 93 of the stairway 91 for getting on and off. It can be connected to the entrance / exit 92 of the aircraft 90.

Next, another embodiment of the swivel floor 25 will be described.
As shown in FIGS. 22 and 23, the swivel floor 25 relates to the above-described floor board main body 27 and has, for example, a floor board portion 38 and a frame portion 39.
The floor board portion 38 is a plate-like member that is long in one direction, and is longer than the floor board body 27 of the above-described embodiment. The floor plate portion 38 is placed on the upper surface of the frame portion 39 on one end side, supported by the frame portion 39, and coupled to the frame portion 39 by the support pins 40. The floor plate portion 38 is placed on the floor surface inside the entrance 92 on the other end side.

  The frame portion 39 is shorter than the floor plate portion 38, and the bearing portion 35 is provided on the lower surface in a direction perpendicular to the plate surface. The floor plate portion 38 and the frame portion 39 are connected to each other by a support pin 40 at one end, and the floor plate portion 38 can rotate with respect to the frame portion 39 with the support pin 40 as a fulcrum. Thereby, when the floor board part 38 is mounted on the floor surface inside the entrance 92, the floor board part 38 can be inclined upward from the head 4 side toward the aircraft 90 side. As a result, it is possible to prevent an excessive load from being applied to the aircraft 90 from the swivel floor 25 of the boarding bridge 1.

  Further, since the floor plate portion 38 is longer than the frame portion 39, the floor plate portion 38 can be inserted into the entrance / exit 92 to a position where the frame portion 39 does not interfere with the entrance / exit stairs 91. Thereby, the space | interval between the handrail 28 attached above the swivel floor 25 and the aircraft 90 can be adjusted, and a passenger can get on and off in a state where the gap is reduced.

  As shown in FIG. 24, the handrail 28 may have a configuration that can extend and contract along the longitudinal direction of the swivel floor 25. In this case, the distance between the aircraft 90 and the handrail 28 can be adjusted without changing the position of the handrail 28 fixed to the swivel floor 25, and passengers can get on and off with the gap being reduced. It becomes possible.

  As shown in FIGS. 5 and 6, the handrail 28 is installed on the floor board main body 27, and can rotate around a rotation shaft 44 parallel to the width direction of the floor board main body 27. When the handrail 28 is accommodated in a position where the swivel floor 25 is retracted from the tip of the head 4 as shown in FIG. 7, the column 45 is positioned below the floor surface of the floor plate body 27 as shown in FIG. 6. Defeated by rotating. Further, when used as the handrail 28, as shown in FIG. 5, the column 45 of the handrail 28 is rotated and stood up. The handrails 28 are provided at both ends in the width direction of the floorboard body 27, and both the handrails 28 may be configured to be independently rotatable. As shown in FIG. It is good also as a structure which can be combined and can be rotated simultaneously. Further, the handrail 28 may be provided with a lock mechanism so that the handrail 28 is fixed when it is tilted and when it is raised. Furthermore, the handrail 28 may be configured to be manually rotated, or may be configured to be mechanically rotated with a driving device.

  Furthermore, as shown in FIG. 25, the handrail 28 may include an auxiliary mechanism 48 configured to reduce a load during a manual standing operation. For example, the torsion spring 49 is inserted through the rotary shaft 47, one end 49 a of the torsion spring 49 is fixed to the handrail 28, and the other end 49 b is fixed to the floor board body 27. The torsion spring 49 is attached in an excessively twisted state in the rotational direction at the time of lifting in order to give a rising load when the standing operation is performed. Thereby, the force which an operator gives when performing a standing operation by manual operation can be reduced.

  As another embodiment of the auxiliary mechanism 48, as shown in FIG. 26, an elastic member such as a gas spring 61 may be installed between the handrail 28 and the floor plate body 27 to which the handrail 28 is fixed. . The gas spring 61 has one end 61 a fixed to the handrail 28 and the other end 61 b fixed to a support member 27 </ b> B provided at the lower part of the floorboard body 27. The gas spring 61 is attached so as to be in an extended state when the handrail 28 stands up and in a contracted state when stored.

  As shown in FIG. 5, the handrail 28 has a girder 62 parallel to the longitudinal direction of the floorboard body 27. Further, as shown in FIGS. 24 and 27, a second girder 63 may be installed below the girder 62 in parallel with the girder 62. As shown in FIG. 24, the second girder 63 may have a configuration that can be expanded and contracted together with the girder 62.

  As shown in FIGS. 27 and 28, the handrail 28 provided on the floor board main body 27 may be provided with a cover 64 that blocks the passage side and the outside side. The cover 64 is provided so as to cover, for example, between the diagonal member 65 of the handrail 28 and the floor surface of the floorboard body 27. At the lowermost portion of the cover 64, an arm portion 66 fixed to the column 45 of the handrail 28 so as to be rotatable is installed. By rotating the arm portion 66 around the rotation shaft 67, the cover 64 can be expanded as shown in FIG. 27, or the cover 64 can be folded as shown in FIG. When the handrail 93 of the boarding / exiting stair 91 is removed, a large gap is formed between the floorboard body 27 and the handrail 28, which may cause anxiety to passengers and children may fall. As shown in FIG. 27, by installing the cover 64, these possibilities can be reduced.

  As shown in FIG. 28, when the handrail 93 of the staircase for getting on and off 91 is still attached, the cover 64 of the handrail 28 may interfere with the handrail 93 of the staircase 91 for getting on and off. Therefore, interference between the cover 64 and the handrail 93 of the stairs 91 for getting on and off can be prevented by folding the cover 64 as shown in FIG.

  The handrail 28 may have a configuration in which the cover 64 of the handrail 28 can be installed in a state where the handrail 93 of the staircase 91 for getting on / off is attached. That is, as shown in FIG. 31, a gap 68 is formed between the floorboard body 27 and the handrail 28 of the floorboard body 27 so that the handrail 93 of the staircase for getting on and off 91 can be inserted, and this gap 68 is formed. The handrail 93 of the stairway 91 for getting on and off does not easily interfere with the floorboard body 27 or the handrail 28.

  Further, as shown in FIG. 29, the swivel floor 25 may have a configuration that can expand and contract in the length direction. The swivel floor 25 has a movable floor 69 that is movable in the length direction with respect to the floor board body 27. When the floorboard body 27 is installed up to the vicinity of the entrance 92 of the aircraft 90, the movable floor 69 is extended from the floorboard body 27. Thereby, the space | interval of the clearance gap formed between the entrance / exit 92 of the aircraft 90 and the floor board main body 27 can be narrowed. Further, the movable floor 69 may be configured to be manually expanded and contracted, or may be configured to be mechanically expanded and contracted with a driving device. Furthermore, the swivel floor 25 having the movable floor 69 may be used in combination with the handrail 28 having a configuration that can expand and contract along the longitudinal direction of the swivel floor 25 shown in FIG.

  As shown in FIGS. 30 and 31, the floor plate body 27 of the swivel floor 25 may have a configuration that can be expanded or reduced in the width direction. During the operation of bringing the head 4 of the boarding bridge 1 close to the aircraft 90, the floorboard body 27 is reduced, and conversely, the floorboard body 27 is installed up to the vicinity of the entrance / exit 92 of the aircraft 90, When placed on the floor surface, the floorboard body 27 is expanded.

  When connecting the swivel floor 25 to the entrance / exit 92 of the aircraft 90, as shown in FIGS. 30 and 31, the floor plate body 27 of the swivel floor 25 is inserted between the handrails 93 of the two staircases 91 for getting on and off, and The handrail 93 of the stairway 91 for getting on and off is inserted between the floorboard body 27 and the handrail 28 of the swivel floor 25. Therefore, the handrail 28 of the floorboard main body 27 or the swivel floor 25 is close to the handrail 93 of the stairway 91 for getting on and off.

  Therefore, when the head 4 is brought close to the entrance / exit 92 of the aircraft 90, as shown in FIG. 30, the floor plate body 27 or the handrail 28 of the swivel floor 25 is moved by reducing the swivel floor 25 in the width direction. It becomes difficult to contact with the handrail 93 of the stairway 91 for getting on and off, and the operation on the boarding bridge 1 side is facilitated. As a result, it is possible to increase the moving speed of the boarding bridge 1 and shorten the time until the connection with the aircraft 90 is completed. When the swivel floor 25 is disposed at a position where it is connected to the entrance 92 of the aircraft 90, as shown in FIG. 31, the floor board body 27 is expanded in the width direction, thereby preventing passengers from getting on and off. A wide passage can be provided.

  As shown in FIG. 32, the swivel floor 25 having a structure that can be expanded or reduced in the width direction is, for example, an auxiliary plate 27D that is a plate-like member connected to a main body portion 27C of the floor plate main body 27 by a hinge 70. Is further provided. The rotation axis of the hinge 70 is provided in parallel to the longitudinal direction of the main body portion 27C. As shown in FIG. 32 (A), the auxiliary plate 27D is arranged so that the plate surface is parallel to the floor surface of the main body portion 27C during expansion, and as shown in FIG. Arranged in a folded state. The auxiliary plate 27D may be formed such that an end portion when expanded extends upward, and the cross-sectional shape may have an L shape.

  The hinge 70 is provided on the upper surface of the main body portion 27C. In this case, as shown in FIG. 33 (A), when a force acts on the vicinity of the end portion of the auxiliary plate 27D from above, the end portion of the main body portion 27C serves as a fulcrum, and an upward force acts on the hinge 70.

  On the other hand, as shown in FIGS. 33 (B) and 33 (C), when the groove 71 is formed in the main body portion 27C below the hinge 70 and the auxiliary plate 27D is expanded, the hinge 70 and A load receiving plate 72 that covers the end of the floor plate 27E of the main body 27C is installed. As a result, as shown in FIG. 33B, the upward force acting on the end of the main body portion 27C acts on the floor plate 27E of the main body portion 27C, so that the upward force is not easily applied to the hinge 70. Become. As a result, the size of the hinge 70 can be made compact, and it becomes difficult for a passenger to walk.

  The groove 71 formed in the main body portion 27C of the floor plate main body 27 not only accommodates the load receiving plate 72 when the auxiliary plate 27D is expanded, but also includes the auxiliary plate 27D as shown in FIG. A space in which the load receiving plate 72 moves when the state is reduced and folded is secured.

  As shown in FIGS. 30, 31, 34, and 35, the swivel floor 25 may be provided with a transition plate 73 that covers a gap between the head 4 and the swivel floor 25. The transition board 73 is, for example, a plate-like member connected to the floor board body 27 of the swivel floor 25 by a hinge 74. The rotation axis of the hinge 74 is provided in parallel to the width direction of the floor board body 27. Another hinge 75 is provided in the intermediate portion of the transition plate 73 in the length direction, and the transition plate 73 has a two-stage folding structure. As a result, as shown in FIG. 7, when the swivel floor 25 is accommodated in a position retracted from the tip of the head 4, the transition plate 73 is folded as shown in FIGS. 34 (B) and 35 (B). In this state, the floor plate main body 27 and the floor plate main body 27 can be accommodated in a position retracted from the tip of the head 4.

  The swivel floor 25 having a structure that can be expanded or reduced in the width direction is not limited to the case where the auxiliary plate 27D is installed via the hinge 70 illustrated in FIG. 32 and the like, and may be realized by other configurations.

As shown in FIG. 36 (A), the auxiliary plates 27F overlap each other at the time of reduction, and as shown in FIG. 36 (B), the auxiliary plates 27F are arranged so that the ends are in contact with each other. Alternatively, as shown in FIG. 38, the floor plate 27E of the main body 27C is formed thicker by the thickness of the auxiliary plate 27F. In this case, as shown in FIG. 38 (A), the auxiliary plate 27F is disposed in the central portion of the floor plate main body 27 when reduced. As shown in FIG. 38 (B), the auxiliary plate 27F is disposed in a stepped portion 27G formed by the thickness of the floor plate 27E during expansion.

  As shown in FIG. 37B, the support arm 76 is coupled to the auxiliary plate 27F and the pin 77 on the end side, and the auxiliary plate 27F rotates with respect to the support arm 76 around the pin 77. Is possible. Thereby, the two auxiliary plates 27F can be overlapped or separated from each other.

  Further, unlike the example described above, the support arm 76 is coupled to the main body portion 27C of the floor plate main body 27 on one end side by a pin 78 as shown in FIGS. 39 and 40, and on the other end side to the auxiliary plate 27F and the pin 79. May be combined. As a result, the auxiliary plate 27F has a configuration capable of turning in a plane parallel to the floor surface of the floor plate body 27. In this case, as shown in FIG. 39, the auxiliary plates 27F overlap each other at the time of reduction, and as shown in FIG. 40, the ends contact each other at the time of expansion.

  Further, as shown in FIGS. 41 and 42, the support arm 76 may have a two-stage folding structure, and is further coupled by a pin 80 at an intermediate portion. Also in this case, the auxiliary plate 27F has a configuration capable of turning in a plane parallel to the floor surface of the floor plate body 27. As shown in FIG. 41, the auxiliary plates 27F overlap each other at the time of reduction, and as shown in FIG. 42, the end portions contact each other at the time of expansion.

  As described above, according to the present embodiment, the floor board body 27 of the swivel floor 25 has a configuration that can be expanded or reduced in the width direction. 27 or the handrail 28 of the swivel floor 25 is less likely to come into contact with the handrail 93 of the staircase 91 for getting on and off, and the operation on the boarding bridge 1 side is facilitated. As a result, it is possible to increase the moving speed of the boarding bridge 1 and shorten the time until the connection with the aircraft 90 is completed. When the swivel floor 25 is arranged at a position where it is connected to the entrance / exit 92 of the aircraft 90, the floorboard body 27 is expanded in the width direction, thereby providing a wide passage for passengers. it can.
