(Embodiment)
[Background to obtaining this embodiment]
The inventor is working on the development of a rail mechanism for a cable carrier for a boarding bridge. In the course of this development, we found that there is still room for improvement with regard to simplification and cost reduction of the cable carrier rail mechanism.
For example, FIG. 5 is a view showing an example of a passenger boarding bridge having a rail mechanism of a conventional cable carrier.
As shown in the enlarged view of FIG. 5, two horizontal shaft rollers 215 are attached to a roller bracket portion 217 on a support 214 of a cable tray 211 that accommodates the cable guide 212, and the roller bracket portion 217 includes bolts, It is connected to the roller support portion 218 by a pin support structure P composed of a bearing or the like.
As a result, as shown by the arrows in FIG. 5, even when the front outer tunnel portion 20 is slightly inclined upward or downward with respect to the rear inner tunnel portion 20, the roller support flexibly follows this movement. The portion 218 can be swung back and forth with the pin support structure P as a fulcrum. Therefore, even in the above case, it is possible to apply a load evenly between the two horizontal axis rollers 215 and the guide rail 216. Therefore, when the full length of the tunnel portion 20 is expanded and contracted, the horizontal axis roller 215 is guided. It can roll smoothly on the roller surface of the rail 216.
However, as a result of intensive studies, the inventors have come up with a rail mechanism that does not require the pin support structure P described above.

Hereinafter, specific examples of the present embodiment will be described with reference to the drawings. In the following description, the same or corresponding elements are denoted by the same reference symbols throughout the drawings, and redundant description may be omitted.
[Device configuration]
Drawing 1 is a figure showing an example of a passenger boarding bridge provided with a rail mechanism of a cable carrier of an embodiment.

  The passenger boarding bridge 100 according to the present embodiment includes a plurality of tunnel units 10 and a cable carrier 40. Hereinafter, for the sake of convenience, the direction in which the entire length of the tunnel portion 10 of the passenger boarding bridge 100 expands and contracts is defined as the front-rear direction, the direction in which gravity acts on the passenger boarding bridge 100 is defined as the up-down direction, It demonstrates as a left-right direction.

  The tunnel portion 10 is configured such that adjacent tunnel portions 10 are fitted in a nested manner in a relative relationship between the outside and the inside, and the entire length of the tunnel portion 10 is configured to be extendable in the front-rear direction. Specifically, a drive column (not shown) is connected to an appropriate position of the tunnel portion 10 (specifically, a portion on the front end side of the tunnel portion 10) so as to sandwich the tunnel portion 10 therebetween. Therefore, when the drive wheel at the lower end of the drive column travels on the apron, the power of the expansion and contraction motion in the front-rear direction is transmitted to the tunnel portion 10. When the cab (not shown) arranged at the front end of the tunnel portion 10 reaches the aircraft entrance / exit by extending the entire length of the tunnel portion 10, the entrance / exit of the airport terminal building and the entrance / exit of the aircraft A walking path for passengers between is formed.

The cable carrier 40 includes a cable tray 11, a cable guide 12, a support body 14, and a rail mechanism of the cable carrier 40. Accordingly, the flexible cable guide 12 including the power cable for the passenger boarding bridge 100 is accommodated in the cable tray 11 of the cable carrier 40. The cable guide 12 is also called a cable bear (registered trademark), and is a cable moving device that can store a power cable, a communication cable, and the like and has a chain structure including a fixed end 12F and a moving end 12M. .
Then, by configuring the cable guide 12 to be flexible, the relative position of the moving end 12M and the fixed end 12F changes synchronously with respect to the movement of the tunnel portion 10, whereby the tunnel portion 10 moves. When it does, it can protect a power cable etc. from a twist and a disconnection.
Specifically, the cable tray 11 is disposed below the rear inner tunnel portion 10, and one end of the cable guide 12 is fixed to the lower portion of the front outer tunnel portion 10 as a moving end 12M using a support member. The other end of the cable guide 12 is fixed to the substantially central portion of the cable tray 11 as a fixed end 12F. For this reason, the relative position of the moving end 12M and the fixed end 12F of the cable guide 12 changes so as to synchronize with the movement of the front outer tunnel portion 10 in the front-rear direction. For example, when the total length of the tunnel portion 10 is shortened so that the front outer tunnel portion 10 is moved backward, the length G of the free span portion 12S of the cable guide 12 is shortened. 11 is accommodated.
Next, details of the support 14 and the rail mechanism of the cable carrier will be described with reference to FIGS. 1, 2, 3, and 4.
The front end of the cable tray 11 is attached to the support 14, a pair of left and right horizontal shaft rollers 15 </ b> R and 15 </ b> L attached to the support 14 and spaced apart in the direction of the shaft 50, and the lower portion of the front outer tunnel portion 10. A pair of left and right guide rails 16R, 16L are connected to the front outer tunnel portion 10.
Further, a pair of left and right vertical shaft rollers 18R and 18L in which the direction of the shaft 60 is vertical are respectively attached to the support 14 in the vicinity of the horizontal shaft rollers 15R and 15L.
In other words, the support body 14, the horizontal shaft rollers 15R and 15L, the vertical shaft rollers 18R and 18L, and the guide rails 16R and 16L constitute the rail mechanism of the cable carrier of the present embodiment.
As shown in FIG. 1, the rear end portion of the cable tray 11 is also connected to the rear inner tunnel portion 10 using an appropriate connection support member.

Here, the support body 14 is configured by combining a plurality of parts using appropriate connection means (bolts, bearings, welding, etc.).
First, the horizontal shaft rollers 15 </ b> R and 15 </ b> L are attached to the upper end portion of the horizontal shaft roller bracket portion 17 of the support 14.
Further, the vertical shaft rollers 18R and 18L are attached to both ends of the vertical shaft roller bracket portion 19 of the support 14.
The horizontal shaft roller bracket portion 17 and the vertical shaft roller bracket portion 19 are fixed to each other by appropriate fixing means such as welding.
A tray support portion (not shown) is attached to the lower portion of the horizontal axis roller bracket portion 17, and the cable tray 11 is fixed to the tray support portion.
As described above, the cable tray 11 can be supported in the vertical direction by the contact between the horizontal shaft rollers 15R and 15L and the guide rails 16R and 16L. When the front outer tunnel portion 10 moves, the horizontal shaft rollers 15R and 15L roll on the rail surfaces 30R and 30L of the guide rails 16R and 16L along the moving direction of the main tunnel portion 10. Therefore, the cable tray 11 can be moved so as to follow the above movement. At this time, the vertical shaft rollers 18R and 18L roll in contact with the rail side surfaces 31R and 31L of the guide rails 16R and 16L, respectively. That is, the vertical shaft rollers 18R and 18L serve as guide portions for the direction of the shaft 50 of the horizontal shaft rollers 15R and 15L. As a result, when the tunnel portion 10 is viewed in plan view from above and below, the horizontal axis roller is applied even when forces in such a direction that the center lines extending in the longitudinal direction of the adjacent tunnel portions 10 deviate from each other depending on the traveling state of the drive column. It can suppress that 15R and 15L contact the rail side surfaces 31R and 31L of the guide rails 16R and 16L.
Here, in the conventional passenger boarding bridge 200, as shown in the enlarged view of FIG. 5, the roller bracket portion 217 is connected to the roller support portion 218 by a pin support structure P including a bolt, a bearing, and the like.
On the other hand, in this embodiment, such horizontal pin rollers 15R and 15L are provided on the left and right sides, so that such a pin support structure is not required. This is due to the following reason.
When the rail mechanism of the cable carrier 40 is viewed from the direction of the axis 50 of the horizontal axis roller 15R (FIG. 3), the horizontal axis roller bracket portion 17 of the support 14 is centered on the axis 50 of one horizontal axis roller 15R. The tunnel portion 10 is configured to be swingable in the moving direction (front-rear direction). That is, even when the front outer tunnel portion 10 is slightly inclined upward or downward with respect to the rear inner tunnel portion 10, the horizontal axis roller bracket portion 17 is moved to the axis of the horizontal axis roller 15R following this movement. It can be swung back and forth with 50 as a fulcrum. Therefore, even in the above case, the horizontal axis roller 15R can be smoothly rolled on the roller surface 30R of the guide rail 16R when the tunnel portion 10 is extended and contracted. The same applies to the left horizontal shaft roller 15L.
Thereby, in this embodiment, the pin support structure P in the support body 214 of the cable tray 211 as shown in FIG. 5 can be eliminated. Therefore, the rail mechanism of the cable carrier 40 can be configured simply and at low cost.
In the present embodiment, as shown in FIG. 2, the horizontal shaft rollers 15R and 15L are arranged inside the rail side surfaces 31R and 31L. For this reason, since the horizontal axis rollers 15R and 15L and their peripheral portions are protected by the rail side surfaces 31R and 31L, dust and the like are not easily accumulated on the rail surfaces 30R and 30L, and are not easily exposed to rainwater. Therefore, the rail mechanism of the cable carrier 40 can be configured not to be influenced by the surrounding environment.

  According to one aspect of the present invention, a rail mechanism for a cable carrier for a boarding bridge that can be simplified and reduced in cost as compared with the prior art can be obtained. Therefore, one embodiment of the present invention can be used for, for example, a passenger boarding bridge.
