Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention is a monorail with a vertically elongated cross-sectional shape, in which the upper edge where the grooved wheels of the movable bogie fit, and the guiding roller of the movable bogie. This invention relates to a monorail for supporting and guiding a movable trolley, which is comprised of a lower edge that contacts and a vertical wall that connects the two.

(Prior art) As this type of monorail, for example,
-Like the monorail described in Publication No. 51301,
It is known that a hollow structure is used to reduce weight, but the surface of the upper edge where the grooved wheels of the mobile cart fit is formed into an arcuate curved surface to withstand vertical loads. Was.

(Problem to be solved by the invention) In such a conventional configuration, the grooved wheels fit into the arcuate curved surface of the upper edge of the monorail, so the surface pressure between the two increases, and the grooved wheels Not only does it prevent the wheels from rolling smoothly, but they are also prone to wear and tear. Therefore, it is conceivable to provide an oblique plane at the center of the surface of the upper edge of the monorail where the grooved wheels fit, but since it is a hollow structure, the upper edge is likely to buckle, causing problems in terms of strength. .

(Means for Solving the Problems) In order to solve the above-mentioned conventional problems, the present invention is a monorail with a vertically elongated cross-sectional shape, and has an upper edge into which the grooved wheels of a mobile trolley fit. ,
The lower edge on which the guide rollers of the movable cart come into contact and the vertical wall connecting the two have a hollow structure, and the upper wall at the upper edge has an oblique plane at the center in the width direction. The cross section has a curved surface curving downward on both the left and right sides, and within this upper edge, there is a pair of diagonal partitions that are inclined so as to connect the center position in the width direction of the upper wall and the left and right side walls of the vertical wall. This paper proposes a monorail for supporting and guiding movable carts that is provided with walls.

(Function of the invention) According to the above monorail of the present invention, since the upper wall center of the upper edge of the monorail where the grooved wheels fit is provided with an oblique surface, the fitting between the grooved wheels and the upper edge of the monorail is prevented. It is possible to reduce the surface pressure between the two at the same time. Moreover, since the vertical load acting on the flat surface can be effectively distributed and transmitted to the left and right side walls of the vertical wall by the pair of diagonal partition walls, the flat surface is formed on the upper wall of the upper edge of the hollow structure. It is possible to prevent a decrease in strength due to this, and to sufficiently increase the strength of the upper edge portion that supports the grooved wheel.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

The drive motor 9 is connected to the power supply rail 17
Operated by power supplied from a to 17c,
It is remotely and automatically controlled from the ground side via signal transmission and reception rails 18a and 18b.

Brackets 19 support the monorail 1 at a predetermined height in the air, and are arranged at appropriate intervals in the length direction of the monorail 1. The upper end is attached to the ceiling beam 20, and the lower end is attached to the monorail 1 via the mounting plate 21. It is attached to the other side (the side opposite to the side that supports the power supply rail 17a etc.).

According to the above configuration, the power supply rails 17a to 17
By operating the motor 9 with electric power supplied from c through the current collecting means 15, the rotation of the drive shaft 8 is controlled through the reduction transmission gear group 10 in the gear case section 4 and the horizontal transverse rotating shaft 5. The signal is transmitted to the grooved wheel 7. By rotating the grooved wheels 7 in this manner, the self-propelled trolley 2 travels along the monorail 1. and,
By cutting off the power to the motor 9, the self-propelled trolley 2
stops.

The motor of the present invention can be used as a motor 1 for supporting and guiding the self-propelled cart 2 as described above, and as shown in FIG. Upper edge 6, guide roller for self-propelled trolley 2 (vertical shaft roller 12a for steady rest)

By providing the wall within the hollow upper edge, the surface pressure between the grooved wheels of the movable trolley and the upper edge of the monorail is reduced, and smooth rolling and wear and tear of the grooved wheels is reduced. Although it is possible to reduce the load, the strength of the upper edge of the hollow monorail is sufficiently increased to create a monorail that is highly safe and can withstand large loads.
It has now become possible to use it effectively.
