Description

The present disclosure relates to a boarding bridge.

A boarding bridge is, for example, a tunnel-like passage connecting an airport and an aircraft, allowing passengers to get on and off directly between the terminal building and the aircraft. The boarding bridge includes a plurality of tunnel portions (passage portions) fitted in a nested manner, and these tunnel portions expand and contract by moving relative to each other in the longitudinal direction. This allows for the various distances that occur between the terminal building and the aircraft.

To operate the boarding bridge, not only the head and tunnel are moved to the aircraft side by the traveling device, but also the turning angle, height position, and horizontal direction of the head are determined according to the position and angle of the boarding gate of the aircraft. It is necessary to adjust multiple items such as the position and the tilt angle of the head floor. In addition, Patent Document 1 discloses a technique for moving a bumper provided at a front portion of an inclined floor of a cab (head).

Since the floor of the head is conventionally composed of a fixed floor fixed to the main body of the head, in order to match the boarding gate of the aircraft with the opening of the head, the traveling device of the boarding bridge is moved. Therefore, it was necessary to adjust the positions of the tunnel and the head. However, since the tunnel portion turns around a fixed position on the terminal building side, the operator needs to move the traveling device in consideration of the turning locus of the head provided at the tip of the tunnel portion. That is, it is difficult for the head to move the head linearly to the target position as seen by the operator, and the head is installed in advance at a position assuming a turning locus, and the head is brought closer to the aircraft from there (contacting machine). )It is carried out.

The turning locus of the head is affected by the turning angle of the tunnel at the time of contact, and the turning angle of the tunnel changes depending on the installation position of the boarding bridge, the model of the aircraft, and the position where the aircraft is stopped. .. Therefore, in the operation of the boarding bridge, it was difficult to match the boarding gate of the aircraft with the opening of the head.

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

In order to solve the above problems, the boarding bridge of the present disclosure includes a tunnel portion and a head portion provided at the tip of the tunnel portion and having an opening for passengers to enter and exit, and the head portion is provided with the boarding / alighting.

A fixed leg 6 is fixedly installed on the ground at the lower part of the rotunda 2. The boarding bridge 1 is supported by the movable legs 5 and the fixed legs 6. The base end tunnel 3a and the tip end tunnel 3b form a tunnel portion 3, and the tunnel portion 3 and the head 4 can be moved by the movable legs 5. The rotunda 2 may be supported by the terminal building and the fixed legs 6 may not be installed at the lower portion.

The cross-sectional area of the hollow portion of the tip tunnel 3b is larger than the cross-sectional area of the base tunnel 3a. The tip tunnel 3b moves along the outer peripheral surface of the base tunnel 3a. The total length of the tunnel portion 3 is extended by moving the tip tunnel 3b to the parking side of the aircraft, and the total length of the tunnel portion 3 is contracted by moving the tip tunnel 3b to the rotunda 2 side. The tunnel portion of the present disclosure is not limited to the combination of the two tunnel portions of the base end tunnel 3a and the tip end tunnel 3b, and may have three or more tunnel portions connected to each other and have a two-stage or more expansion / contraction mechanism. Good.

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

The tip tunnel 3b moves in the longitudinal direction and the left-right direction of the proximal tunnel 3a and the tip 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 parallel to the horizontal direction provided in the rotunda 2. The movable leg 5 can be adjusted in the height direction of the tip tunnel 3b by the elevating device 10. The elevating device 10 includes, for example, a motor and a ball screw mechanism. Therefore, the height of the movable leg 5 is adjusted, and the base end tunnel 3a, the tip end tunnel 3b, and the head 4 are tilted according to the height of the aircraft by rotating in the vertical direction about the rotation axis. The tunnel.

Since the boarding bridge 1 expands and contracts in this way and rotates in the left-right direction and the up-down direction around the rotation axis provided in the rotunda 2, the boarding bridge 1 is moved according to the parked state of the aircraft. Can be properly connected to the aircraft.

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 traveling motor with a speed reducer or a transmission mechanism.
The traveling unit 7 is not limited to the above-mentioned example, and for example, only one set of two wheels 9 may be provided, or two sets of two wheels 9 may be provided.

The traveling speed of the traveling unit 7 can be adjusted by changing the rotation speed of the wheels 9. The turning angle (steering angle) of the wheel 9 in the traveling portion 7 with respect to the length direction of the tip tunnel 3b is the difference in the rotational speeds of the two wheels 9 and the rotational directions of the two wheels 9 (positive). It can be adjusted by changing the rotation or reversal).

Hereinafter, the head 4 according to the present embodiment will be described.
The head 4 has a space inside which passengers can pass, and one side of the head 4 is connected to the tip of the tip tunnel 3b. The other side of the head 4 is formed with an opening to serve as an entrance / exit for passengers to enter and exit, and can be connected 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 rotatable with respect to the tip tunnel 3b. As a result, the opening of the head 4 can be directed toward the aircraft regardless of the extending direction of the tip tunnel 3b.

As shown in FIG. 1, the head 4 includes a floor portion 12, a cover portion 13, and a canopy portion 14. The head 4 has a function of manually or automatically adjusting the height and length of the floor portion 12 of the head 4 in response to the vertical movement of the aircraft by using a sensor or a mechanical mechanism.

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 with respect to the fixed floor 15. Here, the front-rear direction is a direction connecting the opening side of the head 4 and the tunnel portion 3 side.

The movable floor drive unit 17 may have a first drive unit 17A provided on one end side in the width direction of the movable floor 16 and a second drive unit 17B provided on the other end side in the width direction. The first drive unit 17A moves one end side of the movable floor 16 in the width direction in the front-rear direction, and the second drive unit 17B moves the other end side 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. 5, one end side in the width direction is moved forward from the other end side, and conversely, as shown in FIG. 6, the other end in the width direction is moved. The side can be moved forward of one end side.

The movable floor 16 can have a different amount of movement on one end side in the width direction of the movable floor 16 and a different amount of movement on the other end side. As a result, the direction of the tip of the head 4 at the floor 12 with respect to the boarding gate of the aircraft can be quickly and easily adjusted without changing the positions of the tunnel 3 and the head 4 by the traveling unit 7.

The movable floor drive unit 17 may be provided only on one end side 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 side in the width direction can be moved forward or backward from the other end side. As a result, the amount of movement of the movable floor 16 on the other end side in the width direction is fixed to 0 (zero), and the amount of movement of the movable floor 16 on one end side in the width direction and the amount of movement on the other end side of the movable floor 16 are different. become.

The adjusting floor 18 is, for example, a plate material having a hinge portion 20 (see FIGS. 14 and 15) provided obliquely with respect to the tip end portion of the opening of the head 4, and the adjusting floor 18 with respect to the movable floor 16 of the head 4. By changing the tilt angle of 18, the levelness of the floor of the aircraft head 4 can be adjusted. The adjusting floor driving unit can drive the adjusting floor 18 to adjust the levelness of the adjusting floor 18. The configuration of the adjustment floor 18 is not limited to the above-mentioned example.

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 adjusting floor 18, that is, on the side in contact with the aircraft to be connected. When the tip of the boarding bridge 1 comes into contact with the aircraft, the deformation of the bumper portion 19 prevents an excessive load from being applied to the aircraft. The bumper portion 19 is provided along the width direction of the floor portion 12 in a region where there is a possibility of contact with an aircraft.

In the above embodiment, the case where the adjusting floor 18 is installed has been described, but the present disclosure is not limited to this example. For example, as shown in FIG. 3, the floor portion 12 may be configured such that the adjusting floor 18 is not provided, but the fixed floor 15 and the movable floor 16 are provided. Even in this case, the amount of movement of the movable floor 16 on one end side in the width direction and the amount of movement on the other end side of the movable floor 16 can be different from each other, as in the case where the adjustment floor 18 is installed.

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

As shown in FIGS. 7 and 8A or 8B, the main body 35 of the floor 12 is provided with frame members 21 along the side surfaces of the head 4 on both sides of the head 4 in the width direction. A vertical load support roller 22 is installed on each frame member 21.

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 vertical load support roller 22 is provided between the two surfaces of the support portion 23, and in the example shown in FIG. 8B, the vertical load support roller 22 is provided on each of the upper and lower sides. It is provided by being sandwiched between. The rotation axis of the vertical load support roller 22 is parallel to the in-plane direction of the movable floor 16. The vertical load support roller 22 can smoothly move the movable floor 16 in the front-rear direction while restricting the movement in the vertical direction.

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

The left and right guide rollers 25 are rotatably fixed by the support member 26 installed on the frame member 24, and the outer peripheral surface is in contact with the 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-shaped member as shown in FIG. 11B. In the example shown in FIG. 11A, the left and right guide rollers 25 are provided between the 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 vertical with respect to the in-plane direction of the movable floor 16. The left and right guide rollers 25 can make the movable floor 16 move smoothly in the front-rear direction while restricting the movement in the width direction, that is, in the left-right direction.

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

A distance detection unit (not shown) that can detect the distance to the aircraft may be provided at a predetermined position on the floor unit 12. The distance detection unit 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 unit and a memory. The drive control unit controls the drive of the movable floor drive unit 17. The operation of the control device is realized by executing a pre-recorded program and using hardware resources such as a CPU.

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

The movable floor 16 can have a different movement amount on one end side in the width direction and a movement amount on the other end side of the movable floor 16 by the drive control unit. As a result, the direction of the tip of the head 4 at the floor 12 with respect to the boarding gate of the aircraft can be quickly and easily adjusted without changing the positions of the tunnel 3 and the head 4 by the traveling unit 7.

As shown in FIG. 26, even when the width direction of the boarding gate 71 of the aircraft 70 and the width direction of the floor portion 12 of the head 4 are not parallel, as shown in FIG. 27, the width direction of the tip portion of the floor portion 12 is The direction of the movable floor 16 can be adjusted so as to be 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 and the head 4.

As shown in FIGS. 25 and 26, the head 4 has, for example, a configuration capable of turning with respect to the tunnel portion 3. As a result, by combining with the movement of the movable floor 16 in the front-rear direction, the range in which the movable floor 16 can be moved in a direction parallel to the width direction of the boarding gate of the aircraft without changing the positions of the tunnel portion 3 and the head 4 Can be made larger. For example, as shown in FIG. 25, when the boarding port 71 of the aircraft 70 and the opening of the head 4 are misaligned, the tunnel portion 3 or the tunnel portion 3 or the movable floor 16 is moved in the front-rear direction by turning the head 4 or moving the movable floor 16 in the front-rear direction. As shown in FIG. 27, the amount of misalignment 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 floor 16 can move parallel to the fixed floor 15 in 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 is fixed. Therefore, by combining with the movement of the movable floor 16 in the front-rear direction, the tunnel portion 3 and the head It is 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 4.

In the example shown in FIG. 30, wall portions 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 floor 15. As a result, even when the movable floor 16 moves in the width direction, the inside of the head 4 can be made a closed space.
Further, the configuration in which the movable floor 16 moves with respect to the fixed floor 15 in the width direction of the head 4 is not limited to the example shown in FIG. 30, and may be the example shown in FIG. 31. In this case, the inside of the head 4 is closed by providing the protruding portions 43 protruding outward in the width direction at both ends of the fixed floor 15.

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

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

The canopy portion 14 is, for example, a bellows-shaped hood. The canopy portion 14 can be expanded and contracted in the front-rear direction as the tip end side of the canopy portion 14 moves. As shown in FIGS. 16 to 18, the canopy portion 14 has a cloth portion 31 and a plurality of hood frame portions 32. The cloth portion 31 is a sheet made of, for example, a synthetic fiber. Each hood frame portion 32 is a gate-shaped member, and is made of, for example, spring steel or the like. A plurality of hood frame portions 32 are installed along the passage of the canopy portion 14. The lower end of the canopy portion 14 is connected to the movable floor 16.

Unlike the present embodiment, as shown in FIG. 33, when the lower end portion of the canopy portion 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 portion 14 moves so as to cover the aircraft 70 side, a gap is formed below the canopy portion 14.

On the other hand, as shown in FIGS. 16 to 20, all of the lower end portions of the canopy portion 14 according to the present embodiment are 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 unit 14 also moves. As a result, since the canopy portion 14 moves with the movement of the movable floor 16, as shown in FIG. 32, it becomes difficult for a gap to be formed below the canopy portion 14, and the intrusion of wind and rain can be suppressed.

The canopy portion 14 according to the present embodiment is not limited to an example in which all the lower end portions of the canopy portion 14 are connected to the movable floor 16, and as shown in FIGS. 21 to 24, the lower end portion is in the front-rear direction. One end may be connected to the movable floor 16 and the other end of the lower end portion in the front-rear direction may be connected to the fixed floor 15. In this case, the hood frame portion 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 can move in the front-rear direction along a rail provided on the movable floor 16.

As a result, from the state where the movable floor 16 is located on the tunnel portion 3 side as shown in FIGS. 21 and 23, the movable floor 16 is located on the aircraft 70 side as shown in FIGS. 22 and 24. By moving to the present state, the canopy unit 14 also moves. As a result, the canopy portion 14 moves with the movement of the movable floor 16, so that a gap is less likely to be formed below the canopy portion 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 the present embodiment will be described.
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 swiveled so that the opening of the head 4 is directed toward the boarding gate 71. Next, as shown in FIG. 27, only the movable floor 16 is moved without moving the head 4 and the tunnel portion 3 forward. For example, the right side in the width direction of the movable floor 16 is moved forward according to the gap formed between the boarding gate 71 and the opening.

As a result, the width direction of the tip of the floor portion 12 becomes parallel to the width direction of the boarding gate 71 simply by moving the movable floor 16 forward without moving the head 4 and the tunnel portion 3 forward. The movable floor 16 can be arranged in.

In the above-described example, not only the movable floor 16 on the right side in the width direction but also the movable floor 16 on both sides in the width direction is moved so that the amount of movement on the right side in the width direction is larger than that on the left side in the width direction. You may. As a result, 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.

Further, by driving the adjusting floor 18 after bringing the movable floor 16 closer to the boarding port 71 side of the aircraft 70, the inclination angle of the adjusting floor 18 changes, and the difference between the inclination of the boarding port 71 and the inclination of the head 4 Can be made smaller.
