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

When the self-propelled vehicle 1 runs, the rotational force of the motor 10 is transmitted to the propulsion rotating wheel 16 via the deceleration device 14 and the drive shaft 15.
and transfers this propulsion rotating wheel 16 to the friction rolling surface 3
This can be done by pressing and rolling on 6. At this time, traveling is caused by the rolling of the first wheel 4 against the first travel guide surface 34 and the rolling of the second wheel 7 against the second travel guide surface 35.
, and the rolling of the lateral movement regulating wheels 8 and 9 relative to the third traveling guide surface 37, the vehicle is stably moved along a fixed path 5, such as a horizontal or inclined path, without any shaking. On the ascending and descending slope paths, the pinion gear 17 engages with the rack 38, allowing the vehicle to travel without slipping.

During such traveling, the coils 44, 45
When not energized, the sensors 19 and 20 that pass between the two magnetic pole plates (protrusions) 43A and 43B
does not receive a stop signal. However, as shown in FIG. 7, since the sensor 46 detects the magnetic flux (self-propelled vehicle signal) A generated in the vertical direction from the permanent magnet 21, the self-propelled vehicle 1 Passing (being present in a certain section) is detected, and the detection signal is given to the control section. When the designated self-propelled vehicle 1 is stopped at a designated place (station), the coils 44 and 45 corresponding to the location where the self-propelled vehicle 1 was stopped before the self-propelled vehicle 1 arrives are energized. Then the first
As shown in FIGS. 4 and 6, both magnetic pole plates 43
A horizontal magnetic flux (stop signal) B is formed between the upper ends of A and 43B, and therefore the sensors 19 and 20, which have moved together with the self-propelled vehicle 1, detect the magnetic flux B. The motor 10 is stopped and the brake is applied. 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 traveling on a curved route, the self-propelled vehicle 1 is swung outward due to centrifugal force, and the sensors 19 and 20
and the permanent magnet 21 will also move outward,
At this time, as shown in FIG.
3B and the outer protrusions 50A and 50B are formed low, so that no collision occurs between them.

In the above embodiment, the removable insulating covers 49, 49a are provided in the slit 39 that communicates the self-propelled vehicle guide part 32 and the equipment arrangement part 33, so that by removing the insulating covers 49, 49a, the equipment can be removed. Cleaning inside the arrangement section 33, inspection and confirmation of the control equipment 42,
It is possible to replace the control device 42, change the installation position, etc.

In addition, the self-propelled vehicle guide portion 32 is formed to have a C-shaped cross section, and the installation locking portions 60 are formed at both outer ends in the width direction of the equipment placement portion 33 connected to the self-propelled vehicle guide portion 32. As a result, the work of attaching and detaching the rail device 30 to the erection locking portion 60 can be done from the outside of the rail device 30, and also eliminates the need to adjust the width L of the self-propelled vehicle guide portion 32. The attachment and detachment work can be done easily. In addition, by providing the equipment placement section 33 on the rail device 30, the control equipment 4 can be installed simultaneously with the installation of the rail device 30.
2 can also be installed all at once.

In the above embodiment, the sensors 19 and 20 are attached to both the front and rear ends of the self-propelled vehicle 1, but they may be attached only to one side. By attaching two of them, the rear one will work better in the event of an overrun, and it will be possible to travel both forward and backward.

In the above embodiment, the control device 42 includes the coils 44, 4
Although the sensor 5 and the sensor 46 are shown as a set, the sensor 46 may be arranged separately.

Effects of the Invention According to the present invention having the above configuration, when the erection tools are applied to the erection locking part from the outside, these erection tools are positioned within the stepped space and within the width of the self-propelled vehicle guide part. This makes it possible to downsize the construction structure, which is particularly advantageous when placed inside a clean duct. Furthermore, when disposed without using a duct, both exposed sides can be made smooth and the appearance can be improved. In addition, by forming the self-propelled vehicle guide part into a C-shaped cross section and by forming locking parts for erection at both outer ends in the width direction of the equipment placement part connected to the self-propelled vehicle guide part, the rail Attaching and detaching the device can be done from the outside of the rail device relative to the erection locking portion, and there is no need to adjust the width of the self-propelled vehicle guide, making it easy to attach and detach the rail device. . Further, by providing the equipment placement section on the rail device, the control equipment can be installed at the same time as the rail device is installed.
