A scaffold board 18 is constructed via two horizontally parallel members 17 at a position corresponding to the central space.
These scaffolding boards 18 are constructed so as to leave a space 19 for the worker to ascend and descend between them and the end portion of the bottom framework 4 to which the connecting vertical framework 5a is connected. In addition, in order to use the space between the two inner supports 15 at the overlapping parts of the two connecting vertical frames 5a connected to each other in each stage frame 1 to 3 as a ladder 20 for lifting workers, the inner side is A horizontal member 21 is installed between the pillars 15. This horizontal member 21 can be constructed on either one or both of the vertical frame 5a for connection on the side of the intermediate frame units 1b-3b and the vertical frame 5a for connection on the side of the end frame units 1a-3a, 1c-3c. . Furthermore, Fig. 1, Fig. 2,
As shown in FIG. 5, a scaffold board 22 is installed on one side of the upper end of the end frame units 3a, 3c of the upper frame 3 adjacent to the vertical linking frame 5a. This scaffold board 2
2 may be constructed at a location adjacent to the vertical framework 5a for connecting both ends of the intermediate frame unit 3b, or
It is also possible to install on both sides.

Incidentally, as shown in FIG. 5, the rotary rack device in this embodiment has a height that projects above the floor surface 23 of the second floor. And the floor surface 23 of the second floor
A ladder 24 for lifting and lowering workers between the upper frame 3 and a scaffold board 22 installed on the upper end of the upper frame 3 is attached to the side of the assembled rotary rack device.

When installing the above rotary rack device at the installation site, each frame unit 1a manufactured at the factory
~1c, 2a~2c, 3a~3c are individually transported to the site, connected and integrated with each other at the installation site, and installed at a predetermined position. Both inner and outer guide rails 9,1
0, the drive gear 12, the free rotation gear 13, the drive motor 11, and other attachment parts are all or partially attached to predetermined frame units 1a to 1c,
It can be attached to 2a to 2c and 3a to 3c. Both the inner and outer guide rails 9, 10 are pre-assembled into frame units 1a-1c, 2a-2c, 3a-3c.
When the frame units are connected to each other, the guide rails 9 and 10 are naturally separated at the position of the connecting vertical frame 5a of each frame unit, and when the frame units are connected, the guide rails 9 and 10 are continuous with each other. It is configured as follows.

Once the entire frame has been installed at the installation site, the mounting parts that were not previously attached to the frame unit are attached to the specified positions, and the 7 groups of trays connected by the chain 14 are supported on the tray horizontal circulation path 8 of each stage. At the same time, the chain 14 is assembled into an endless shape and hung between both gear wheels 12 and 13.
After that, if necessary, as shown in FIG. 4, cover plates 25 and the like are stretched at required locations on the outside, and the ladder 24 is attached. Of course, this ladder 24 is designed so that it can be used from the ground where the rotating rack device is installed.
You can also attach long ones.

The 7 groups of trays on the tray horizontal circulation path 8 of each stage are rotated in any direction for each stage by rotating the endless drive chain 14 between the gear wheels 12 and 13 by the drive motor 11. This is similar to the conventional rotary rack device in that any tray 7 can be called to a preset loading/unloading position in this way. Inside this tray horizontal circulation path 8, a tray detector for automatic control and the like are also installed. When performing maintenance inspections on the tray detector and other attached parts, the operator uses the ladder 24 to climb onto the scaffolding board 22 at the top of the rotary rack device, and from there, the operator can access the ladder 20 and the operator elevating space 19. on the scaffolding board 18 located at the center of the bottom of the middle or upper frames 2, 3, or on the floor at the center of the bottom of the lower frame 1 (a scaffolding board may also be installed on the frame side at this location). ). Therefore, the worker
Using these scaffolding boards 18 and the like, inspection and repair can be carried out at any lengthwise location in the tray horizontal circulation path 8 at any height of the rotary rack device.

Although the scaffold board 18 was installed only at the center of the bottom of the middle and upper frames 2 and 3, a plurality of scaffold boards 18 could be installed on each stage frame 1 to 3 depending on the height of each stage frame 1 to 3. It can also be constructed. On the other hand, if the height of the entire rotating rack device is low, the scaffolding board 18 can be erected only at the intermediate height position of the entire rotating rack device (in the case of the embodiment, the intermediate height position of the middle frame 2). However, if the height of the entire rotary rack device is low, the scaffold board 18 can be omitted,
It is also possible to configure the worker to pass through the lowermost end (above the floor surface) of the horizontally elongated central space surrounded by the tray horizontal circulation path 8.

The rotary rack device of the present invention can be implemented as described above, and its feature is that it is a rotary rack device in which a horizontally long horizontal circulation path in which a large number of load supporting means rotates in series is stacked in multiple upper and lower stages. A ladder (ladder 20 in the embodiment) used for ascending and descending the worker between the horizontally long central space surrounded by the horizontal circulation path and the outside of the upper end of the rotary rack device is placed inside the horizontally long central space. A scaffolding board (scaffolding board 22 in the embodiment) is provided at a location adjacent to the top end of the ladder on the outside of the upper end of the rotating rack device, and a scaffolding board (scaffolding board 22 in the embodiment) is provided on the outside of the rotating rack device, the upper end of which is adjacent to the scaffolding board. The point is that an external ladder (ladder 24 in the embodiment) is provided for the purpose.

According to the rotary rack device of the present invention,
As described in detail in the embodiments, an operator operates the rotary rack device in the internal space of the rotary rack device, that is, in the horizontally elongated central space surrounded by the horizontal circulation path of the load supporting means stacked in multiple stages. You can easily climb down from the top. Therefore, it has become possible to carry out maintenance and inspection work from the inside of each level horizontal circulation path, which was previously impossible with this type of rotating rack device, and it has now become possible to maintain this type of rotating rack device in good condition. be.

In particular, as shown in the embodiments, the ladder for lifting workers can be constructed economically by using a part of the frame.

In the embodiment, the frame is divided into vertical and longitudinal directions, but it is also possible to construct the frame as a single piece. Furthermore, although a ladder 24 for moving onto the outside of the upper end of the rotary rack device is fixedly installed on the outside side of the rotary rack device, it is possible to use a ladder that can be freely hooked on and removed from the rotary rack device instead of this ladder 24. You can also do it.
