Hereinafter, an embodiment of a rotander and a 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 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 for the connection portion of the extension bridge BBu has a configuration in which a general rotander 10 and a bifurcated rotander 10A described later are combined.

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 of the present embodiment is obtained by adding one connection port 14A to the general rotander 10, and in this case, none of the connection ports 12A, 13A, 14A is on the same straight line. .

  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. In addition, in this embodiment, although one connection port 14A was added, it is also possible to add two connection ports as needed.

Further, it is desirable that 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, the bifurcated rotander 10A can use the existing rotander post Sf supporting the rotander 10 as it is, as shown in FIG. 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. 2 (b), the rotander 10 whose position is to be reused is newly provided with a stationary leg portion (ground mounting leg portion) 50 that does not require foundation work. To support. 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 rotander unit 10U according to the present embodiment includes the bifurcated rotander 10A that forms a space portion serving as a passage relay portion.
This bifurcated rotander 10A includes a connecting port (building structure connecting port) 12A in which a rotander main body 11A that forms a space portion of a passage relay unit is connected to an opening for getting on and off the fixed bridge FB, and tunnel portions 20 and 20A. Two connection ports (tunnel connection ports) 13A and 14A that are directly or indirectly connected to the base end side opening.

For this reason, it is possible to get on and off between the fixed bridge FB on the terminal side and the two boarding ports L2 and U1 by the two tunnel portions 20 and 20A connected so as to branch from one bifurcated rotander 10A. A passenger boarding passage for books can be formed.
Moreover, the bifurcated rotander 10A provided with the two connection ports 13A and 14A connected to the tunnel portions 20 and 20A replaces the rotander main body 11A with the rotander main body 11 of the existing rotander 10, thereby replacing the existing rotander post Sf. It is possible to easily form two passenger boarding passages by making effective use.

  That is, the boarding bridge structure of the present embodiment in which the fixed bridge FB, which is a building structure on the terminal building side, and the aircraft AP, which is a passenger vehicle, are connected to form a passenger getting-on / off passage is the bifurcated bridge described above. The rotander 10A and two tunnel portions 20 and 20A that are directly or indirectly connected to the two connection ports 13A and 14A for tunnels provided in the bifurcated rotander 10A are provided. Indirect in this case means that the bifurcated rotander 10A is connected to the tunnel portion 20 or the tunnel portion 20A via the existing rotander 10.

As a result, two passengers who can get on and off between the fixed bridge FB and the two boarding ports L2 and U1 by the two tunnel portions 20 and 20A connected so as to branch from one bifurcated rotander 10A. The boarding / alighting passage can be easily formed.
In particular, if a bifurcated rotander 10A, an intermediate rotander 10B, a tunnel portion 20A provided with a head portion 30, a movable leg 40, and at least two sets of mounting-type support legs 50 are prepared, foundation work and building work can be performed. Without having to do so, it is possible to add passenger boarding passages, so the construction period (delivery time) can be shortened and the delivery time can be reduced at a low cost.

In the embodiment described above, the rotander unit 10U is formed by using the existing rotander 10, but, for example, the existing rotander 10 and the bifurcated rotander 10A are not directly connected but a plurality of intermediate rotanders 10B. You may use as one of these. That is, a tunnel portion in which a plurality of intermediate rotanders 10B exist by providing a tunnel portion between the forked rotander 10A and the existing rotander 10 in accordance with the situation of the location to be expanded, the position of the boarding gate to be connected, and the like It is also possible to have a layout of
In addition, this invention is not limited to embodiment mentioned above, For example, it can apply also to the boarding bridge for ships etc., Therefore, in the range which does not deviate from the summary, it can change suitably.
