A rack 38 is provided near the second traveling guide surface 35 and is engaged with the pinion gear 17 on an inclined path or the like. A slit 39 for arranging rail-side equipment and various types of wiring is formed over the entire length of the other side plate portion of the self-propelled vehicle guide portion 32.
9 connects both parts 32 and 33. An insulating strip 4 is provided at the end of the self-propelled vehicle guide section 32 where the slit 39 is formed.
0A and 40B are fitted and installed, and these insulating strips 40A
, 40B are equipped with power supply rails 41A, 41B on which the collectors 18A, 18B slide.

The rail-side equipment 42 arranged from the slit 39 into the equipment arrangement section 33 includes, for example, a pair of left and right magnetic pole plates 4.
3A, 43B, and a pair of front and rear coils (stop signal transmitter) 44.45 provided between these magnetic pole plates 43A, 43B,
Both magnetic pole plates 43A are configured with a sensor (self-propelled vehicle signal receiver) 46 provided between these coils 44 and 45,

A plurality of wires 25 are provided to connect to the duct portion 2, and these wires 25 are installed on the inner surface of the duct portion 33 via fittings 26. The width of the duct portion 33 is narrower than the width of the self-propelled vehicle guide portion 32, so both side surfaces of the rail device 30 are formed in a stepped shape. A construction locking part 51 is formed in a concave shape at the outer end of the side surface of the duct part 33. A groove 28 is provided in the ceiling 27 with a width corresponding to the width of the duct portion 33.
is formed, and by fitting the duct portion 33 into this groove 28.

The rail device 30 is arranged with respect to the ceiling 27 with its opening 31 facing indoors (facing downward). The erection tool 52 disposed behind the ceiling 27 includes a pair of engaging pieces 53 that can be freely engaged with and detached from the locking portion 51 from the outside, and these engaging pieces 5
3, and a hanging iron 56 which is fastened and connected to both engaging pieces 53.

Next, the traveling operation of the self-propelled vehicle 1 in the above embodiment will be explained.

When the self-propelled vehicle 1 is running, the rotational force of the motor 10 is transferred to the deceleration device 14.
, and transmitted to the propulsion rotating shaft 16 via the drive shaft 15.

This can be done by pressing and rolling the propulsion rotating shaft 16 on the friction rolling surface 36. At this time, traveling is performed on the first traveling guide surface 3.
Transfer of the first wheel 4 to 4, transfer of the second wheel 7 to the second travel guide surface 35, and transfer of the second wheel 7 to the second travel guide surface 37
Due to the shifting of the lateral movement regulating wheels 8.9, the movement is carried out stably on a fixed path 5, such as horizontal or inclined, without shaking. In the ascending and descending inclined paths, the pinion gear 17 engages with the rack 38, so that the vehicle can run without slipping.

During such traveling, when the coils 44 and 45 are not energized, both magnetic pole plates (convex portions) 43A.

Sensors 19 and 20 passing between 43B do not receive the stop signal. However, as shown in FIG.
6, it is detected that the self-propelled vehicle 1 has passed the location where this sensor 46 is installed (that it is present in the section), and the detection signal is given to the control section. When the designated self-propelled vehicle 1 is stopped at a designated location (station), the coils 44 and 45 corresponding to the designated location are energized before the self-propelled vehicle 1 arrives. Then, as shown in FIGS. 1 and 4, a horizontal magnetic flux (stop signal) B is formed between the outer ends of both magnetic pole plates 43A and 43B, and therefore the vehicle moves together with the self-propelled vehicle 1. The sensors 19 and 20 detect the magnetic flux B, thereby stopping the motor 10 and applying the brake. As a result, the self-propelled vehicle 1 is stopped after traveling the braking distance. Due to this stop, the permanent magnet 21 faces the sensor 46, detects the magnetic flux A in the same manner as described above, and the control unit confirms the stop.

When installing the wiring 25 and rail-side equipment 42 inside the duct part 33, or performing maintenance and inspection of these 25 and 42, first remove the insulating covers 49 and 49a, and then insert the Perform various tasks.

In the above example, it is a rail device! 30 is disposed on the ceiling 27 side, but it may also be disposed on the floor side via the machine frame. In this case, various operations can be performed through the opening 31 and the slit 39.

Effects of the Invention According to the present invention having the above-mentioned configuration, when the rail device is installed on the ceiling or the floor, various wiring work inside the duct, as well as maintenance and inspection work after wiring, can be carried out using the opening and the slit. These operations can be easily performed with fewer man-hours.
