In the monorail type transporting device of the type in which the driving wheels for traveling roll in the center position of the upper surface of the upper rail portion of the guide rail, the guide rail has a cross-sectional shape of substantially symmetrical I-shape. Was there.

In such a conventional configuration, the recessed spaces on both the left and right sides of the vertical connecting portion connecting the upper and lower rail portions of the guide rail are equal in size, and the upper and lower rail portions are driving wheels for traveling. The width of the recessed space could not be made wide because of the minimum required width corresponding to the width.

For this reason, there is provided a power supply rail unit that is fitted and mounted in the recessed space on one side of the vertical connection portion of the guide rail, that is, the recessed space on the side opposite to the U-shaped open side of the transportation train. Since it largely projects laterally from the recessed space, it is necessary to sufficiently separate the portion of the transport train adjacent to the power supply rail unit from the guide rail. Not only was it an obstacle in reducing the width of the car, but the weight balance was poor.

[Operation and effect of the device]

 The present invention can be implemented as described above, and according to the guide rail of the present invention, the vertical connecting portion 4 connecting the upper and lower rail portions 2 and 3 is formed in the width direction of the upper and lower rail portions 2 and 3. Shift from the central position to a position slightly inside the side surfaces of the upper and lower rail portions 2 and 3 on the U-shaped open side of the transport train 8 and into the recessed spaces 21 and 22 on both sides of the vertical connection portion 4. Since there is a difference in size and the recessed space 22 on the side where the power feeding rail unit 5 that slides in contact with the current collecting unit 14 of the transport train 8 is attached is made large, all or almost all of the power feeding rail unit 5 is recessed. It can be installed by being buried in the entry space 22.

In other words, the amount of protrusion of the power supply rail unit 5 protruding laterally from the guide rail can be eliminated or reduced without particularly increasing the horizontal width of the upper and lower rail portions 2 and 3 of the guide rail. Therefore, it is possible to reduce the lateral width of the transportation train 8 having a substantially U-shaped front shape, in which the side on which the power feeding rail unit 5 is located extends laterally from the guide rail, and to improve the left-right weight balance.

In addition, the upper and lower rail portions 2 and 3 are formed in a hollow shape, and the upper rail portion 2 has an upper surface side central position, the vertical coupling portion 4 has a right upper position, and the lower rail portion 3 has a lower surface side central position. Since the diagonal reinforcing connecting portions 23 and 24 connecting the position and the position directly below the vertical connecting portion 4 are integrally formed in the upper and lower rail portions 2 and 3, the weight of the entire guide rail is reduced. The load of the transport train 8 acting on the guide rail via the drive wheels 9 for traveling of the transport train 8 rolling on the center of the upper surface of the upper rail 2 and the lower side of the transport train 8 The backup reaction force acting on the guide rail from the back-up roller 13 rolling in the center of the lower surface of the rail portion 3 can be reliably and satisfactorily transmitted to the vertical connecting portion 4 via the inclined reinforcing connecting portions 23 and 24. From now on, there is no risk of concentrating bending stress at the connecting portion between the upper and lower rail portions 2 and 3 and the vertical connecting portion 4.
