As shown in FIGS. 1 to 5, a pair of upper and lower rails 2 and 3 made of a steel pipe constituting a track 1 are spaced apart from each other and placed on the ground via a support 4 which is electrically insulated. It is laid almost horizontally. The rails 2 and 3 are electrically insulated from each other by an insulating support member 5 and are integrated.
The upper rail 2 is connected to the negative side of the DC drive power supply P as a return line of the drive current, and the lower rail 3 is connected to the positive side of the DC drive power supply P as a forward line of the drive current.

[0007] A traveling body 6 traveling on the track 1 has a pair of vertical support wheels 7, 7 rolling back and forth on the upper rail 2 away from each other, and side surfaces thereof while holding the upper rail 2 from both right and left sides. A pair of horizontal guide wheels 8, 8, 9, 9 provided on the left and right, which are provided apart from each other so as to roll, and the front and rear so as to roll the side surfaces while holding the lower rail 3 from both right and left sides. It has a pair of left and right horizontal drive wheels 10, 10 provided between the guide wheels 8, 9.

The support wheels 7 are supported on an axle 12 which is horizontally mounted on a frame 11. The support wheel 7 has an annular groove 7 a having an arc-shaped cross section along the upper curved surface of the upper rail 2 on its outer periphery, and rolls on the upper rail 2 while supporting the load of the traveling body 6.

The guide wheels 8 and 9 are provided on a vertical shaft 1 supported by horizontal support portions 11a extending on both left and right sides of the frame 11.
3 supported. The guide wheels 8, 9 are provided with annular grooves 8a, 9a having an arc-shaped cross section along the side surface of the rail 2, respectively. One pair of guide wheels 9 together with a brush 19 described later forms a current collecting mechanism 14 for energizing the rail 2. In other words, the guide wheel 9 is configured such that the upper and lower sides of the magnet ring 15
6 and a conductive pressing disk 17 above and below it.
The holding disc 17 and the shaft 13 are electrically insulated by an insulating member 18. Although not shown, the shaft 13 is provided so as to be able to approach and separate from the rail 2 within a predetermined range, so that the guide wheel 9 rolls while being magnetically attracted to the rail 2. Brush 19 on holding disc 17
Are slidably in contact with each other, and the brush 19 and the rail 2 are electrically connected via the holding disk 17. The brush 19 is electrically connected to the motor 21 via a conductor (not shown).

The support shaft 20 of the drive wheel 10 is mounted on the frame 1
1 is coupled via a universal joint 22 to a rotating shaft of a drive motor 21 which is vertically mounted on arm members 11b provided on both right and left sides of the arm. The drive wheel 10 includes an annular groove 10 a having an arc-shaped cross section along the side surface of the rail 3. Drive wheel 10
Forms a current collecting mechanism 24 for energizing the rail 3 together with the brush 23 described later. The drive wheel 10 has the same structure as the guide wheel 9 shown in FIG. The brush 23 is slidably in contact with the holding disc 17, and the brush 23 and the rail 3 are electrically connected via the holding disc 17. The brush 23 is electrically connected to the motor 21 via a conductor (not shown).
The drive wheels 10 and the guide wheels 9 together with the rails 2
The magnets are magnetically attracted to the respective side surfaces of No. 3 and collect current while being in contact with each other. Since the drive wheel 10 and the guide wheel 9 are magnetically attracted to the rails 2 and 3, the wire separation rate is low and high current collecting performance is obtained.

In the track running device of this embodiment,
The upper rail 2 and the lower rail 3 function not only as a traveling path of the traveling body 6 but also as a return line of electric power to the drive motor 21. Electric power is supplied from the lower rail 3 as a forward line of current.
It is supplied to the drive wheel 10-brush 23-drive motor 21 and flows from the drive motor 21 through the brush 19-guide wheel 9 to the upper rail 2 as a current return. Thus, electric power is supplied to the drive motor 21 and the drive motor 21 rotates. The rotation of the drive motor 21 is transmitted to the drive wheels 10. The drive wheel 10 rolls on the left and right side surfaces of the rail 3 with strong frictional force due to the magnetic attraction of the magnet ring 15 while electrically conducting to the lower rail 3, and efficiently pulls the traveling body 6.
Each of the wheels 7, 8, 9, and 10 has an annular groove 7a, 8a, 9a, and 10a that engages with the rails 2, 3, and therefore, if the positioning accuracy of the wheels is low, the wheels 7, 8, 9, 10 are displaced from the rails 2, 3. Resistance occurs in rolling. However, since the drive wheel 10 is located between the front and rear guide wheels 8 and 9 and the support wheels 7 and 7 and is in contact with the rails 2 and 3 at the support points arranged at the vertices of the triangle, the wheel placement accuracy is high. Is relatively low, the displacement between the wheel and the rail is unlikely to occur. The support wheels 7 support the load of the traveling body 6 and roll on the upper surface of the upper rail 2. Guide wheels 8,
9 determines the horizontal position of the traveling body 6 and guides traveling along the rail 2.

FIG. 6 shows another embodiment of the present invention. In this embodiment, the arrangement of the guide wheels 8 and 9 and the drive wheel 10 is turned upside down, and the guide wheels 8 and 9 roll on the side surface of the lower wheel 3 and the drive wheel 10 rolls on the side surface of the upper wheel 2 respectively. It is configured as follows. Other configurations are basically the same as those of the previous embodiment.

The present invention is not limited to the above embodiment. For example, the current collecting mechanism can be configured independently of the wheels 9 and 10, and the drive power supply path is connected to the rails 2 and 3. It can be provided separately. When the guide wheel 9 is not a part of the current collecting mechanism, it is not necessary to incorporate the magnet ring 15 into the current collecting mechanism. Instead, a separate biasing means such as a spring may be employed.
