Description

  The present invention relates to a boarding bridge.

  Conventionally, a boarding bridge has been used as a device for getting passengers on and off passenger aircraft. As passenger aircraft, an aircraft having a guest room on the second floor in addition to a guest room on the first floor is known. In this type of conventional aircraft, the boarding bridge is connected to the entrance / exit provided in the guest room on the first floor, and passengers on the second floor get on and off via the guest room on the first floor. That is, passengers on the second floor have been getting on and off using boarding bridges connected to the first floor of the aircraft.

  In recent years, the size of aircraft has increased, and aircraft with many second-floor seats have been developed. Therefore, when getting on and off via the guest room on the first floor, it takes a lot of time for all passengers on the second floor to complete the boarding and getting off. However, recently, the number of arrivals and departures of aircraft at airports is increasing, and there is a demand for shortening the staying time at the gates of aircraft.

  Therefore, the present inventor devised connecting the boarding bridge to the second floor portion of the aircraft. However, when attempting to connect the boarding bridge to the second floor, the height of the tunnel where the passenger walks increases from the ground, and the tunnel is likely to roll due to vibration during walking and external wind from the outside. Therefore, when walking through a tunnel, passengers may feel uneasy or the walking speed may be slow, which may hinder rapid getting on and off.

The following Patent Document 1 discloses a mover device for preventing the roll of a tunnel. The mover device includes a mover frame that is provided below the tunnel and holds the tunnel. This mover frame is provided with wheels and legs. When the boarding bridge is moved, the legs are separated from the ground and only the wheels are grounded.When the boarding bridge is fixed, the wheels are separated from the ground and the legs are grounded. It has become.
Japanese Utility Model Publication No. 61-108700

  However, simply adding the mover device to the conventional boarding bridge causes a time delay associated with the operation of the mover device, and increases the time required for mounting the boarding bridge. Therefore, even if the walking time of the passenger can be shortened, the waiting time becomes long, and as a result, it is difficult to sufficiently shorten the getting-on / off time. Therefore, as a whole, it is difficult to sufficiently shorten the aircraft gate stay time.

  This invention is made | formed in view of this point, The place made into the objective is providing the boarding bridge which can get on and off the passenger of the 2nd floor seat of an aircraft rapidly.

  A boarding bridge according to the present invention includes a telescopic tunnel portion in which a walking passage is formed, a cab provided in the tunnel portion and connected to an entrance of an aircraft, and a height between the cab and the entrance. An auto-leveler that adjusts the position, a drive column that supports the tunnel portion, and moves the tunnel portion up and down so that the cab can be connected to both the first floor entrance and the second floor entrance and exit of the aircraft, A wheel attached to the drive column, a support column movable up and down, an outrigger that assists the support of the tunnel portion by the drive column, and the operation of the auto leveler starts, the support column descends And a control device that drives the outrigger so as to contact the ground.

  In addition, another boarding bridge according to the present invention includes a telescopic tunnel portion in which a walking passage is formed, a cab provided in the tunnel portion and connected to an entrance of an aircraft, the cab and the boarding / exiting An auto-leveler that matches the height position with the mouth, and a drive that supports the tunnel portion and moves the tunnel portion up and down so that the cab can be connected to both the first floor entrance and the second floor entrance A column, a wheel attached to the drive column, a support column that is movable up and down, an outrigger that assists the support of the tunnel portion by the drive column, and the operation of the auto-leveler, the support column is raised And a control device that drives the outrigger to leave the ground.

  According to the above boarding bridge, when the outrigger post descends and touches the ground, the tunnel portion is firmly supported by the post. Therefore, even if there is a vibration during walking or a lateral wind from outside, the rolling of the tunnel portion is prevented. In addition, the outrigger is driven in conjunction with an auto leveler. The auto-leveler starts operation as soon as the cab is connected to the aircraft, and ends operation when the cab is disconnected. Therefore, the outrigger is automatically driven at an appropriate time by interlocking with the auto leveler. Therefore, the boarding / alighting time can be shortened by the synergistic effect of the quick and timely operation of the outrigger and the prevention of the roll of the tunnel.

  Preferably, the control device drives the outrigger when the cab is connected to the second floor entrance / exit of the aircraft, and does not drive the outrigger when the cab is connected to the first floor entrance / exit of the aircraft.

  This makes it possible to shorten the boarding / alighting time when connected to the first floor entrance / exit, compared to the case where the outrigger is always driven.

  It is preferable that the outrigger assists the support of the tunnel portion while the wheel is grounded.

  Thus, the outrigger does not need to lift the tunnel portion until the wheel leaves the ground. Therefore, the load applied to the outrigger is relatively small. Therefore, the outrigger can be reduced in size and cost.

  Preferably, the outrigger includes a ground pressure detection unit that detects a pressure of the support column against the ground, and when assisting support of the tunnel portion, the support column is preferably lowered until the pressure becomes a predetermined value or more.

  As a result, the support column receives a predetermined amount of load and stably supports the tunnel portion.

  The outrigger is preferably provided with an electric motor that moves the column up and down.

  This facilitates control of the outrigger.

  The boarding bridge moves between a mounting position attached to an aircraft and a retracted position retracted from the aircraft, and the tunnel portion is supported by the outrigger in the retracted position while the tunnel portion is lowered and contracted. It is preferable to assist.

  Accordingly, the tunnel portion can be supported by the outrigger in an emergency such as a typhoon.

  As described above, according to the present invention, the outrigger for assisting the support of the tunnel portion is interlocked with the auto-leveler, and the passenger on the second floor seats by the synergistic effect of the quick and timely operation of the outrigger and the rolling prevention of the tunnel portion The time for getting on and off can be shortened.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the boarding bridge system 1 according to the embodiment includes a plurality of boarding bridges 10, 11, and 12 connected to a boarding gate of an airport terminal building 2. The boarding bridge system 1 is compatible with an aircraft 20 having a first floor entrance 21 and a second floor entrance 22. The boarding bridges 10 and 11 are configured to be connected to the first floor entrance / exit 21, and the boarding bridge 12 is configured to be connectable to both the first floor entrance / exit 21 and the second floor entrance 22. In the following description, it is assumed that the boarding bridges 10 and 11 are connected to the first floor entrance 21 and the boarding bridge 12 is connected to the second floor entrance 22.

  The boarding bridge 10 and the boarding bridge 11 have the same configuration. The boarding bridges 10 and 11 are different from the boarding bridge 12 in that the boarding bridge 12 includes an outrigger 30 described later, whereas the boarding bridges 10 and 11 are not provided with the outrigger 30. However, other configurations are almost the same. Therefore, only the configuration of the boarding bridge 12 will be described below, and the description of the configuration of the boarding bridges 10 and 11 will be omitted.

  As shown in FIG. 2, the boarding bridge 12 is rotatable to a rotor (base circular chamber) 4 connected to the boarding entrance of the terminal building 2, a tunnel portion 5 fixed to the rotor 4, and a tip of the tunnel portion 5. And a cab (tip circular chamber) 6 provided at the front.

  The rotor 4 is supported by a column 7 so as to be rotatable about a vertical axis. The tunnel portion 5 is an expandable and contractible cylindrical body that forms a walking passage that connects the terminal building 2 and the entrance / exit 22 of the aircraft 20, and includes a first tunnel 5 a and a second tunnel 5 b. The second tunnel 5b is assembled to be slidable with respect to the first tunnel 5a. And the 2nd tunnel 5b slides with respect to the 1st tunnel 5a, and the whole tunnel part 5 expands / contracts.

  The second tunnel 5 b is provided with a drive column 8 that supports the tunnel portion 5. The drive column 8 is a support column that can be expanded and contracted vertically, and is expanded and contracted by a drive motor (not shown). In the boarding bridge 12, the stroke of the drive column 8 is set long so that the cab 6 can reach the second floor entrance 22.

  A drive wheel 9 is attached to the lower end of the drive column 8. The drive wheel 9 is configured to be able to run and rotate about a vertical axis. As the drive wheel 9 travels, the boarding bridge 12 moves between a standby position away from the aircraft 20 and a mounting position connected to the aircraft 20 (that is, the positions shown in FIGS. 1 and 2). Become. Further, the tunnel portion 5 expands and contracts as the driving wheel 9 travels. Therefore, the drive column 8 also has a function of expanding and contracting the tunnel portion 5.

  As shown in FIGS. 3 and 4, an outrigger 30 is provided at the lower end of the drive column 8 as a roll prevention device. The outrigger 30 includes a pair of left and right cylinders 31, a rod 32, and a support base 33. The rod 32 and the entire support base 33 constitute a support column that moves up and down.

  As shown in FIG. 5, an electric motor 34 is fixed inside the cylinder 31. A worm 36 is fitted on the outside of the shaft 35 of the electric motor 34. A spiral groove is formed on the outer peripheral surface of the worm 36. A block 37 is fixed to the upper end portion of the rod 32, and a slot having a spiral groove is formed on the inner peripheral surface of the block 37. The worm 36 is inserted in a state of being engaged with the groove hole of the block 37. With such a configuration, when the electric motor 34 is driven, the rod 32 and the support base 33 move up and down with respect to the cylinder 31.

  The support base 33 is provided with a pressure sensor 38 that detects a pressure (ground pressure) between the support base 33 and the ground. The configuration of the pressure sensor 38 is not limited at all. The installation position of the pressure sensor 38 is not particularly limited, and may be provided at a place other than the support base 33. Furthermore, the device for detecting the pressure between the support base 33 and the ground is not limited to the pressure sensor 38, and any device can be used. For example, it is possible to indirectly detect the ground pressure based on an overcurrent flowing through the electric motor 34, a change in characteristics, or the like by using the fact that the load of the electric motor 34 increases as the ground pressure increases.

  As shown in FIG. 6, the boarding bridge 12 includes an auto leveler 40. Next, the configuration of the auto leveler 40 will be described.

  The auto-leveler 40 is attached to the lower side of the cab 6 floor (hereinafter referred to as cab floor) 50. At the front end of the cab floor 50, a cushioning material 51 is disposed so as to face the body of the aircraft 20 (not shown in FIG. 6). The auto-leveler 40 includes an electric motor 41, a driving sprocket 42 rotated by the electric motor 41, a driven sprocket 43, a driving chain 44 wound around the driving sprocket 42 and the driven sprocket 43, and a buffer body connected to the driving chain 44. 45. The buffer body 45 includes a cylinder 47 having a compression spring (not shown) and a foil 46.

  When the operation of the auto-leveler 40 is stopped, the shock absorber 45 is in the most retracted position, that is, the retracted position shown in FIG. On the other hand, when the cab 6 approaches the fuselage of the aircraft 20 and the cushioning material 51 comes into contact with the fuselage at the time of mounting, the limit switch 52 is activated and the operation of the auto leveler 40 is started. That is, the electric motor 41 is activated and the shock absorber 45 moves forward. Thereby, the foil 46 moves forward toward the airframe. When the foil 46 comes into contact with the airframe, the foil 46 itself stops, but the shock absorber 45 continues to advance while compressing the compression spring. Thereafter, the limit switch 48 is activated and the electric motor 41 is stopped. Thereby, the forward movement of the buffer body 45 is stopped. The limit switch 52 is adjusted in advance so that the pressing force of the foil 46 to the body surface is optimized.

  When the aircraft rises or descends due to passengers getting on and off, loading or unloading of luggage, etc., the wheel 2 rotates by frictional force with the surface of the aircraft. That is, the foil 2 rotates in the clockwise direction in FIG. 6 when the fuselage is raised, and conversely, it rotates in the counterclockwise direction when the fuselage is lowered. And the signal according to the rotation direction and rotation amount is transmitted, Based on the signal, the cab 6 moves up and down until the height of the cab floor 50 and the entrance / exit 22 matches.

  Next, a control system of the boarding bridge system 1 will be described. As shown in FIG. 7, the boarding bridge 12 is provided with a control device 61 that performs various controls of the boarding bridge 12. For example, the control device 61 controls the drive column 8, the auto leveler 40, and the outrigger 30.

  A central control device 60 that centrally controls the control devices 61 of the boarding bridges 10, 11, and 12 is provided in an airport management room or the like. The central controller 60 receives information such as the type of aircraft arriving at each gate of the airport, and based on the information, information such as the mounting positions of the boarding bridges 10, 11, 12 at each gate is sent to each controller 61. Send.

  The control device 61 of the boarding bridge 12 receives a signal from the central control device 60, and determines whether the boarding / exiting gate to be connected is the first floor boarding gate 21 or the second floor boarding gate 22. When connected to the second floor entrance 22, the control device 61 operates the outrigger 30 in conjunction with the auto leveler 40. On the other hand, when connected to the first floor entrance 21, the control device 61 does not operate the outrigger 30. In other words, when the boarding bridge 12 is connected to the first floor entrance 21, the control device 61 locks the outrigger 30.

  Next, the operation of the outrigger 30 will be described. As described above, the outrigger 30 is driven only when the boarding bridge 12 is connected to the second floor entrance 22.

  The outrigger 30 according to the present embodiment is driven in conjunction with the auto leveler 40. That is, when the operation of the auto leveler 40 is started, the control device 61 activates the electric motor 34 of the outrigger 30 and lowers the support base 33. And the control apparatus 61 will stop the electric motor 34, if the support stand 33 contacts the ground and a grounding pressure becomes more than predetermined value. In other words, the support base 33 automatically stops when the ground contact pressure exceeds a predetermined value. The predetermined value is set to such a pressure that the drive wheels 9 do not leave the ground. Therefore, the outrigger 30 of the present embodiment does not lift the tunnel portion 5 until the driving wheel 9 is separated from the ground. The outrigger 30 of the present embodiment assists the support of the tunnel portion 5 while the driving wheel 9 is grounded.

  On the other hand, when the cab 6 is removed from the aircraft 20 such as when the passenger has finished boarding, the operation of the auto leveler 40 is stopped. When the operation of the auto leveler 40 stops, the control device 61 activates the electric motor 34 of the outrigger 30 and raises the support base 33. And the control apparatus 61 will stop the electric motor 34, if the support stand 33 raises to the predetermined position away from the ground. Note that the height of the support base 33 can be detected by a position sensor or the like. Any known position sensor can be used as the position sensor, and the position sensor is not limited to a specific one.

  As described above, according to the present embodiment, the tunnel portion 5 is firmly supported by the outrigger 30 in the boarding bridge 12 connected to the second floor entrance 22 of the aircraft 20. Therefore, it is possible to prevent the rolling of the tunnel portion 5 located at a high place regardless of vibrations when walking through the tunnel portion 5 or lateral wind from the outside. Therefore, the passenger can walk quickly in the tunnel part 5.

  Moreover, since the outrigger 30 is interlocked with the auto-leveler 40, the support operation by the outrigger 30 can be started at the same time that the cab 6 is connected to the second floor entrance 22. Further, the release operation of the outrigger 30 can be started simultaneously with the cab 6 being removed from the second floor entrance 22. Accordingly, when the boarding bridge 12 is attached and detached, the outrigger 30 can be actuated in a timely manner, and there is no time delay associated with the operation of the outrigger 30. Therefore, the time for attaching and removing the boarding bridge 12 can be shortened.

  Therefore, passengers can walk quickly in the tunnel portion 5 as much as the rolling of the tunnel portion 5 does not occur, and further, by shortening the time for attaching and removing the boarding bridge 12 (in other words, waiting time) As a whole, the boarding / alighting time can be shortened. According to the present embodiment, it is possible to shorten the gate stay time of the aircraft 20, that is, the time until the aircraft 20 arrives at the gate, changes passengers, and departs from the gate.

  In the present embodiment, the boarding bridge 12 operates the outrigger 30 when connected to the second floor entrance 22 and does not operate the outrigger 30 when connected to the first floor entrance 21. Therefore, when connecting to the first floor entrance 21, the time for attaching and removing the boarding bridge 12 can be shortened by the amount that the outrigger 30 is not operated.

  Moreover, according to this embodiment, the outrigger 30 does not need to lift the tunnel part 5 to such an extent that the driving wheel 9 floats. Therefore, the load required for the outrigger 30 can be kept small, and a small or inexpensive outrigger can be used.

  Since the outrigger 30 supports the tunnel portion 5 so that the ground pressure of the support base 33 becomes a predetermined value or more, the outrigger 30 can always support the tunnel portion 5 stably.

  Since the outrigger 30 is driven by the electric motor 34, it is easy to control and can be operated quickly.

  In the embodiment, the outrigger 30 is provided only on a specific boarding bridge 12 among the plurality of boarding bridges 10, 11, and 12 in the boarding bridge system 1. However, it goes without saying that the outriggers 30 may be provided in all the boarding bridges 10, 11, 12. However, it is desirable to operate the outrigger 30 only when it is connected to the second floor entrance 22 without being operated when connected to the first floor entrance 21.

  In the embodiment, the outrigger 30 is electrically operated. However, the outrigger 30 may be hydraulic. The drive source of the outrigger 30 is not limited at all.

  The outrigger 30 can be used not only as a rolling prevention device when passengers get on and off, but also as a rolling prevention device in an emergency such as a typhoon. For example, at the time of a typhoon, after moving the boarding bridge 12 to the standby position (position closest to the airport building) so that the boarding bridge 12 does not fall, the tunnel part 5 is lowered to the lowest position and contracted. The outrigger 30 is activated. As a result, the boarding bridge 12 takes a posture that is not easily affected by the wind, and is supported by the outrigger 30, so there is no risk of overturning even if it receives an extremely strong crosswind.

  In addition, when using as an apparatus for preventing rolling in an emergency, it is desirable to provide the outrigger 30 in all the boarding bridges 10, 11, 12.

  As described above, the present invention is useful for a boarding bridge.
