As shown in FIGS. 2, 3, 8, and 9, the rack for storing the drive control and power supply cables 56 of the traveling bogie 3 is provided between the straight rail sections 4. 6 is supported by the connecting member 35 and provided along the straight rail portion 4. This rack 6 has both side plates 58 bent in a U-shape installed in parallel, and these side plates 58 are connected by a plurality of beam members 59.

A partition plate 60 is arranged in the length direction between the side plates 58, and the lower end of this partition plate 60 is connected to the beam member 59.
is fixed to the top surface of. Both side plates 58 at both ends of the rack 6
In between, there is an end cap 61 bent into a U-shape.
is installed. These end caps 61 are
One end has a screw 62 and a nut 63 on the inner surface of the end of each side plate 58.
It is attached via screws 62 and nuts 63 to the other end of an L-shaped attachment plate 64 attached via screws 62 and nuts 63.

As shown in FIG. 1, the rack 6 is divided into parts so that it can be freely connected to the linear rail section 4. That is, the rack 6 is divided into a first rack 65 and a second rack 66 that can be freely connected to each other, the first rack 65 is installed integrally with the first straight rail section 40, and the second rack 6
6 is installed integrally with the second straight rail section 41.

A connecting plate 68 bent in a U-shape is fitted into the outer surface of the side plate 58 at the joint 67 of the side plate 58 at each connecting portion between the first rack 65 and the second rack 66. 68 is attached between each end of the connected side plates 58 via screws 69 and nuts 70.

The operation of the above configuration will be explained below. When shipping the rail device 1, by dividing the temporarily assembled straight rail portion 4 and rack 6 of the rail device 1, the straight rail portion 4 is connected by a connecting member 35 as shown in FIG. It is divided into two parts, a first straight rail part 40 and a second straight rail part 41, which are parallel and short.

Accordingly, the rack 6 is divided into two parts, a first rack 65 and a second rack 66, the first rack 65 is installed integrally with the first straight rail section 40, and the second rack 66 is installed integrally with the second straight rail section 41.

That is, the division of the straight rail section 4 is as follows:
As shown in FIG. 7, the bolts 25, set screws 44, and countersunk head screws 46 at the connecting portions are removed, the first linear rail portion 40 and the second linear rail portion 41 are separated from each other in the length direction, and the dovetail groove portion 8, 9, the nut body 26 and the connecting plate 43 can be removed. Further, the rack 6 can be divided by removing the screws 69 and nuts 70 at the connecting portion and removing the connecting plate 68, as shown in FIGS. 8 and 9.

As described above, the rail device 1 is shipped in two pieces, transported, and then assembled at the installation site. To assemble the rail device 1, first insert the nut body 26 and the connecting plate 43 into the dovetail grooves 8 and 9, and then bring the end surfaces of the first straight rail part 40 and the second straight rail part 41 into contact with each other in the length direction. Then, the bolt 25 and set screw 44 are tightened, the connecting plate 45 is attached to the groove 10, and the countersunk head screw 46 is tightened. Thereby, the first straight rail part 40 and the second straight rail part 41 are connected.

Next, the end surfaces of the first rack 65 and the second rack 66 are brought into contact with each other in the length direction, and the connecting plate 68 is fitted into the joint 67 of the side plate 58, and the screw 69 and nut 70 are fitted.
All you have to do is tighten it. As a result, the first rack 65
and the second rack 66 are connected. As above,
After assembling the rail device 1, install the cable 5 in the rack 6.
Wire 6.

In the above embodiment, the straight rail section 4 and the rack 6 are integrally divided into two parts, but they may be divided into three or more parts.

[0034]

As described above, according to the present invention, parallel straight rail parts are connected by a plurality of connecting members, and a rack supported by the connecting members is provided between the straight rail parts. By dividing the rail section so that it can be freely connected in the length direction with the intervening connecting material, and by dividing the rack so that it can be freely connected together with the straight rail section, the rail device is temporarily assembled and then separated into racks. teeth,
The rails are divided into a plurality of parallel short straight rail sections, each integrated into one piece, and then shipped. In this way, the divided racks are shipped while being attached to the divided linear rail sections, which saves the effort of removing the racks from the linear rail sections and facilitates the shipping work.

After shipping, the rail and rack can be assembled by connecting the parallel short straight rail parts divided into a plurality of parts and connecting the rack divided into a plurality of parts. These multiple divided racks are pre-installed as one piece on each of the multiple divided straight rail sections, so when connecting these racks, first connect the straight rail sections and then connect the individual racks. The installation location can be determined accurately.

Therefore, there is no need to adjust the installation position by shifting the individual racks in the length and width directions, and the racks can be assembled easily and accurately, improving the ease of assembly at the installation site.
