In recent years, large aircraft equipped with upper and lower two-layered guest rooms have appeared, and it is required that upper-level guest rooms be able to get on and off smoothly.
For this reason, for example, as shown in FIGS. 12 to 14, a boarding bridge BB ′ that directly connects the fixed bridge FB on the airport building side and the boarding entrance U <b> 1 of the upper passenger room of the aircraft AP is added. . The upper-layer boarding bridge BB ′ shown in the figure is provided with an upper-layer fixed bridge FBu that communicates with the doorway opened to the existing fixed bridge FB. Further, on the distal end side of the upper-layer fixed bridge FUu, the upper-layer fixed bridge FBu. And a rotander 10 supported by the fixed leg Sf. A tunnel section 20 for upper-layer passenger seats is connected to the rotander 10 so as to be rotatable in the horizontal direction.

  The tunnel portion 20 has a structure in which a tunnel of a plurality of stages (three stages in the illustrated example) having a cylindrical cross section is fitted in a nested manner, and a head 30 is provided at the end of the tunnel on the tip side (aircraft AP side). Is provided. Moreover, the front-end | tip part side of the tunnel part 20 can be connected and separated with respect to the boarding entrance U1 of an upper passenger room by being supported by the movable leg mentioned above.

However, in such a conventional upper-layer boarding bridge BB ′, a fixed leg Sf that supports the additional upper-layer fixed bridge FBu and the additional rotander 10 is a building structure. For this reason, various procedures related to building structures, foundation work, and the like are required, which causes a problem that the construction period required for the extension is increased, and further, the cost required for the extension is unavoidably increased.
From such a background, it can be applied when, for example, the boarding bridge BB for the upper layer is added, and it is suitable for the extension that can shorten the construction period (delivery time) by eliminating the foundation work and can realize the short delivery time at low cost. A boarding bridge structure is desired.

  The present invention has been made to solve the above-mentioned problems. The purpose of the present invention is to increase the number of boarding bridges that do not require foundation work, shorten the construction period (delivery time), and realize a short delivery time at low cost. The present invention provides a boarding bridge structure suitable for the above.

In order to solve the above problems, the present invention employs the following means.
The boarding bridge structure according to the present invention is a boarding bridge structure that connects a terminal building structure and a passenger vehicle to form a passenger passage, and is fixedly attached to the terminal building structure side. The rotander is connected to a tunnel connection port provided in the rotunda and a boarding port provided in the passenger vehicle to form the boarding passage, and a head portion for connecting the boarding port to the vehicle-side front end portion A telescopic tunnel portion provided with a movable leg that supports the vicinity of the vehicle-side tip portion of the tunnel portion, and a plurality of telescopic tunnel end portions that are divided into a bent state, and the lower surface side is mounted on the ground. And a stationary intermediate rotander supported by a stationary leg portion.

  According to such a boarding bridge structure, a rotander fixedly attached to the terminal building structure side, a tunnel connection port provided in the rotunda, and a boarding port provided in a passenger vehicle are connected to get on and off. A telescopic tunnel part that forms a passage and has a head part for connecting a boarding entrance at the vehicle-side front end part, a movable leg that supports the vicinity of the vehicle-side front end part of the tunnel part, and a telescopic type divided into a plurality of parts The tunnel end is connected to the bent state, and the lower surface is supported by a ground-mounted leg unit, so that the intermediate rotander is supported by the ground-mounted leg unit. By doing so, it is possible to add a telescopic tunnel without any foundation work.

In the above invention, it is preferable that the ground-mounted leg portion is provided with a lifting mechanism for adjusting a support height of the intermediate rotander, thereby responding to fluctuations in the boarding entrance height of the passenger vehicle. Is possible. In other words, passenger vehicles vary in height from the ground surface to the boarding gate depending on, for example, the loading amount of fuel, etc., so adjusting the height of the intermediate rotander can incline the tunnel portion serving as a boarding / exiting passage. It can be mitigated.
In the above invention, the ground-mounted leg portion preferably includes a drive mechanism having a traveling wheel, which facilitates the movement of the intermediate rotander according to the situation.

  According to the present invention described above, by supporting the intermediate rotander by the ground-mounted legs, for example, for an upper-layer cabin of a large aircraft equipped with a cabin of a two-layer structure, a short construction period without performing foundation work A telescopic tunnel can be added at low cost.

Hereinafter, one embodiment of the boarding bridge structure according to the present invention will be described with reference to FIGS.
The boarding bridge connects, for example, an airport terminal building (terminal building structure) and an aircraft (passenger vehicle) AP to form a passenger passage. Note that the boarding bridge of the present embodiment described below is newly added to the upper passenger cabin of a large aircraft having a passenger cabin having a two-layer structure on top of the existing (conventional) boarding bridge BB shown in FIG. Therefore, in the following, this will be referred to as “additional bridge BBu”.

The illustrated extension bridge BBu includes a rotander unit 10U, a tunnel portion 20A including an intermediate rotander 10B, and a movable leg 40.
The rotander unit 10U is provided so as to protrude from the terminal building, and is fixedly attached to the fixed bridge FB that is a part of the terminal building structure, and serves as a connection portion between the fixed bridge FB and the tunnel portion 20A. . In other words, the rotander unit 10U serves as a passage relay part for a passenger boarding / exiting passage from the fixed bridge FB to the tunnel part 20A. In this case, the rotander unit 10U used in the connection portion of the extension bridge BBu has a configuration in which a general rotander 10 and a two-forked rotander 10A described later are combined as shown in FIG. 10, for example.

The general rotander 10 includes a pair of connecting ports 12 and 13 that open to a side surface portion of a rotander main body 11 that forms a substantially cylindrical space serving as a passage relay portion. In this case, the pair of connection ports 12 and 13 are provided in a direction in which the opening direction is deviated from the same straight line, that is, the passenger boarding passage from the fixed bridge FB to the tunnel portion 20 is bent.
On the other hand, the bifurcated rotander 10A is opened at a side surface portion of a rotander main body 11A forming a substantially cylindrical space portion serving as a passage relay portion, and is provided with three connection ports 12A, 13A, and 14A. That is, the bifurcated rotander 10A used in the present embodiment is obtained by adding one connection port 14A to the general rotander 10, and in this case, any of the connection ports 12A, 13A, 14A is on the same straight line. There is no.

  Further, the bifurcated rotander 10A of the present embodiment is substantially the same as the rotander 10 except for the shape and dimensions of the outer diameter, that is, the number and arrangement of the connection ports 12A, 13A, and 14A. And about the opening direction (opening position of a side part) of connection port 12A, 13A, 14A, it can adjust suitably according to various conditions. Note that the number of connection ports of the bifurcated rotander 10A may be added as necessary, and may be four, for example.

Further, the above-described bifurcated rotander 10A is installed in place of the existing rotander 10 fixedly installed at the tip of the fixed bridge FB when the extension bridge BBu is added. The connection ports 12A, 13A, and 14A of the bifurcated rotander 10A serve as a building-side passage where one connection port 12A is connected to the opening for getting on and off the fixed bridge FB and leads to the terminal building, and the remaining two connection ports 13A and 13A, 14A is connected to the existing and additional tunnel parts 20 and 20A.
In the configuration example shown in the figure, the existing tunnel portion 20 connected to the boarding entrance L2 which is the lower rear seat rear entrance is directly connected to the connection port 13A, and the additional tunnel portion 20A interposes the removed existing rotander 10 By doing so, it is indirectly connected to the connecting port 14A. That is, in the existing rotander 10, one connecting port 12 is connected to the connecting port 14A of the bifurcated rotander 10A in place of the opening for getting on and off of the fixed bridge FB, and the other connecting port 13 is connected to the tunnel portion 20A of the extension bridge BBu. Concatenated with

Accordingly, as shown in FIG. 10, the bifurcated rotander 10 </ b> A can use the existing rotander post Sf supporting the rotander 10 as it is. The rotander post Sf is a support column that is fixedly installed with a foundation in the ground, and can be shared by matching the bolt holes of the rotander 10 and the bifurcated rotander 10A.
On the other hand, as shown in FIG. 10, the rotander 10 whose position is to be reused is newly provided and supported by a stationary leg portion (ground mounting leg portion) 50 that does not require foundation work. . The stationary legs 50 are, for example, movable bases that are installed and used on the concrete surface of an apron, and a plurality of (eight in the illustrated example, eight) supporting leg bodies 51 formed by combining steel materials. The outriggers 52 and the like are arranged to prevent overturning.

  The tunnel portion 20A is formed by connecting the connecting port 13 provided in the rotander 10 of the rotunda unit 10U and the boarding port U1 for the upper passenger compartment provided in the aircraft AP to form an entrance / exit passage. By adopting a telescopic structure of the formula, the length in the axial direction is variable. And the head part 30 for boarding entrance connection is provided in the front-end | tip part side (vehicle side front-end | tip part) of the tunnel part 20A connected with aircraft AP. The head portion 30 is connected to the boarding port U1 so as to be in contact with the surface of the aircraft body, thereby connecting the tunnel portion 20A and the interior of the aircraft.

  The tunnel portion 20A includes a movable leg 40 that supports the vicinity of the tip end side connected to the aircraft AP from below. The movable leg 40 is a support frame (support leg) provided with a drive mechanism having traveling wheels 41. By operating this movable leg 40, the tunnel portion 20A is stretched to approach the aircraft AP and the head portion 30 is brought into contact with the airframe surface during the formation of a boarding / alighting passage, or the tunnel portion 20A is pushed in and contracted. The operation of releasing the getting-on / off passage away from the aircraft AP becomes possible.

  And the tunnel part 20A expanded in this embodiment has the axial direction of the tunnel part main body made into the expansion-contraction type divided | segmented into plurality. Specifically, the tunnel portion 20A is divided into a terminal-side tunnel portion 20T and a fuselage-side tunnel portion 20P, and both tunnel portions 20T and 20P are telescopic. However, for the terminal-side tunnel portion 20T, a tunnel structure that does not expand and contract may be employed depending on the support structure of the intermediate rotander 10B described later.

The above-described terminal-side tunnel portion 20T and the fuselage-side tunnel portion 20P are bent in a straight line via a stationary intermediate rotander 10B whose lower surface is supported by a stationary leg portion (ground mounting leg portion) 50. It is connected to. The intermediate rotander 10 </ b> B has substantially the same structure as the rotander 10, and includes two connecting ports 12 and 13 in the rotander main body 11.
The stationary leg 50 used here is substantially the same as the stationary leg 50 that supports the existing rotander 10 described above, and is therefore a supporting leg that does not require foundation work. In other words, the stationary leg 50 is a movable frame that is installed on the concrete surface of the apron and used, and measures against overturning are provided by a plurality of outriggers 52 and the like arranged at appropriate positions. Since the intermediate rotander 10B supported by the stationary leg 50 is semi-fixed so that the intermediate rotander 10B cannot move by itself, a tunnel structure that does not expand and contract may be employed in the terminal-side tunnel portion 20T.

When the extension bridge BBu configured in this way is added to the existing boarding bridge BB, as main components, a bifurcated rotander 10A, an intermediate rotander 10B, a tunnel portion 20A having a head portion 30, The movable leg 40 and at least two sets of mounting-type support legs 50 are required.
When the extension bridge BBu is installed, the existing rotander 10 is first removed from the support leg Sf, so that the connection between the rotander 10 and the tunnel portion 20 and the fixed bridge FB is released. Thereafter, the rotander 10 removed from the support leg Sf is transported to a proper place and stored.

Next, the bifurcated rotander 10A is installed on the support leg Sf from which the rotander 10 has been removed. At this time, since the bolt holes and the like coincide with the rotander 10, the bifurcated rotander 10 </ b> A is installed by using the support legs Sf as they are, and is connected to the tunnel portion 20 and the fixed bridge FB similarly to the rotander 10. .
Further, the connection port 12 of the removed rotander 10 is connected to a connection port 14A provided in addition to the bifurcated rotander 10A. In order to support the rotander 10, a placing-type support leg 50 is used. The mounting-type support leg 50 is installed in a state in which a plurality of outriggers 52 are adjusted and measures for preventing overturning are taken after transporting to a predetermined position using a vehicle or the like. Therefore, foundation work is not required for installing the mounting-type support legs 50, and installation with a short construction period is possible.

In this way, when the bifurcated rotander 10 </ b> A and the rotander unit 10 </ b> U by the rotander 10 are completed, the tunnel portion 20 </ b> A is connected to the connection port 13 of the rotander 10. In this case, the end of the terminal side tunnel part 20T is connected to the connection port 13. And the other end of the terminal side tunnel part 20T is connected with one connection port 12 of the intermediate | middle rotander 10B supported by the mounting type support leg 50 similar to the rotander 10 mentioned above.
Further, the other connecting port 13 of the intermediate rotander 10B is connected to the end portion of the fuselage side tunnel portion 20P supported by the movable leg 40 and provided with the head portion 30 at the front end portion on the aircraft AP side. Accordingly, the intermediate rotander 10B also employs the mounting-type support legs 50, so that no foundation work is required, and installation in a short construction period is possible.

As described above, the boarding bridge structure of the present embodiment, that is, the extension bridge BBu of the present embodiment, is between the fixed bridge FB that is a part of the terminal building structure and the aircraft AP that is a passenger vehicle. It is connected to form a passenger passage.
This extension bridge BBu includes a rotander unit 10U fixedly attached to the fixed bridge FB on the terminal building structure side, a tunnel connection port 13 provided in the rotander unit 10U, and a boarding port U1 provided in the aircraft AP. A telescopic tunnel portion 20A having a heading portion 30 for connecting the boarding entrance at the front end portion on the aircraft AP side, and the vicinity of the front end portion on the aircraft AP side of the tunnel portion 20A The movable leg 40 is connected to the terminal-side tunnel portion 20T and the fuselage-side tunnel portion 20P. The telescopic tunnel end portion is connected in a bent state, and the lower surface side is supported by the placement-type leg portion 50. And a stationary intermediate rotander 10B.

  The extension bridge BBu having such a boarding bridge structure supports the intermediate rotander 10B by a semi-fixed mounting-type leg portion 50 that is used by being mounted on the ground, so that the telescopic tunnel portion 20A can be used without performing foundation work. Can be added. Therefore, for example, when an extension bridge BBu is added to an existing boarding bridge BB that cannot accommodate an upper passenger cabin of a large aircraft equipped with upper and lower two-layer guest rooms, the mounting-type legs 50 that do not require additional foundation work or building structures. With the structure that supports the intermediate rotander 10B, the telescopic tunnel portion 20A can be added inexpensively in a short construction period.

By the way, although the mounting-type leg part 50 mentioned above becomes semi-fixed which cannot run (moving) by itself, for example, like the modification shown in FIGS. 4-6, the self-propelled which provided the drive mechanism 60 which has the running wheel 61 is provided. It may be a formula leg 50A. The illustrated drive mechanism 60 is provided in four sets on the front, rear, left and right in a plan view, each of which includes two traveling wheels 61 and a dedicated electric motor 62.
The self-propelled leg portion 50A is normally supported so that the outrigger 52 is in contact with the ground such as an apron, and is in a semi-fixed state in which the fall is prevented as in the above-described mounting type. However, when the intermediate rotander 10B is moved, the outrigger 52 is lifted from the ground and made independent by the traveling wheels 61, and then the drive mechanism 60 is operated to allow the traveling wheels 61 to travel on their own.

  As a result, the position of the intermediate rotander 10B provided with the self-propelled leg portion 50A can be easily changed. Therefore, for example, the extension bridge BBu can cope with various models and applications by changing the position of the intermediate rotander 10B according to the model of the aircraft AP to be used. That is, the intermediate rotander 10B employing the self-propelled leg portion 50A is easy to move according to the situation, and is effective in improving versatility and convenience.

  Further, the above-described mounting-type leg 50 and the self-propelled leg 50A of the ground-mounting leg include a lifting mechanism 70 that adjusts the support height of the intermediate rotander 10B, as shown in FIGS. It is desirable that In the illustrated configuration example, four sets of lifting mechanisms 70 are provided in the same manner as the driving mechanism 60, but the present invention is not limited to this. Further, the elevating mechanism 70 is not limited to the specific examples described below, and a system using hydraulic pressure or air pressure can also be adopted.

  As a specific example of the elevating mechanism 70, for example, as shown in FIG. 7, there is a screwed structure of a ball screw 72 rotated by an electric motor 71 and a fixed nut 73. In this case, an electric motor 71 is installed at the upper end of an outer cylinder 74 that is connected to and supported by the rotander main body 11, and a ball screw 72 is provided so as to rotate on the inner axis of the outer cylinder 74. On the other hand, the nut 73 screwed with the ball screw 72 is fixed to the upper end portion of the inner cylinder 75 connected to the support leg main body 51 side. The outer cylinder 74 and the inner cylinder 75 are prismatic columns, and a slide pad 76 is interposed between the inner surface of the outer cylinder 74 and the outer surface of the inner cylinder 75.

When such an elevating mechanism 70 drives the electric motor 71 to rotate the ball screw 72 in a desired direction, between the elevating position shown in FIG. 7A and the lowered position shown in FIG. Since the ball screw 72 moves in the vertical direction with respect to the fixed nut 73, the rotander main body 11 can be raised and lowered with respect to the support leg main body 51.
For this reason, since the height from the ground surface to the boarding gate fluctuates according to, for example, the fuel loading amount, the aircraft AP can adjust the height of the intermediate rotander 10B according to the fluctuation in the boarding gate height. become. Such height adjustment of the intermediate rotander 10B is effective, for example, for reducing the inclination of the tunnel portion 20A serving as an entrance / exit passage.

In this way, by supporting the intermediate rotander 10B with the mounting leg 50 and the self-propelled leg 50A, which are the ground mounting legs, for example, for an upper passenger room of an aircraft AP equipped with a passenger cabin having an upper and lower two-layer structure. Therefore, it is possible to add a telescopic tunnel section at a low cost in a short construction period without performing foundation work.
In addition, this invention is not limited to embodiment mentioned above, For example, it can change suitably in the range which does not deviate from the summary, such as being applicable also to the boarding bridge for ships.
