Description

[Detailed description of the invention] Conventionally, in a suspension type monorail, as shown in FIG.
A has no choice but to have an open cross-sectional shape with an opening at the center.

Therefore, the load from the running wheels 4 of the vehicle 2 is transmitted from the running rail 5 to the belly plate 1b of the track girder 1, and a high frequency of repeated bending stress is generated at the intersection point A between the belly plate 1b and the bottom plate 1a. Therefore, as shown in FIG. 2, the track girder 1 deforms as shown by the dotted line due to the load P from the running wheels 4, and the point A becomes a severe design condition.

This project was proposed to eliminate these drawbacks, and involves vertical rail plates being hung from both sides of the box girder-shaped monorail track girder bottom plate facing each other across the central opening for passing the monorail vehicle suspension link. The present invention relates to a suspension type monorail characterized in that guide wheels mounted on both sides of a support member disposed on a suspension link of a monorail vehicle are in sliding contact with the outside of each vertical rail plate.

In the suspension type monorail according to the present invention, as described above, the suspension links of the monorail vehicle are installed on the outside of each rail vertical plate that is vertically hung from both sides of the box girder-shaped track girder bottom plate across the center opening. Since the guide wheels on both sides of the provided support member are in sliding contact, by pressing each of the rail vertical plates from the outside with the guide wheels, the load from the running wheels of the monorail vehicle is applied to the track. Since the downward expansion of the bottom plate of the girder is restrained, the bending moment applied to the intersection between the bottom plate and the bottom plate of the track girder is significantly reduced, the structure of the track girder is simplified, and the strength is improved. Reliability is increased. Furthermore, by disposing the guide wheels of the monorail vehicle on the outside of the track girder, the width of the track girder is reduced, its cross-sectional shape is reduced, and construction costs can be reduced.

The present invention will be described below with reference to the illustrated embodiments.

11 is a track girder in the form of a box girder, and a suspension link 13 of the monorail vehicle 12 is installed in the center of the bottom plate 11a.
An opening is provided for the passage of.

Vertical rail plates 14 are vertically hung from both sides of the bottom plate 11a facing each other across the central opening, and support members 1 disposed on the suspension links 13 are provided.
Guide wheels 16 mounted on both sides of the rail 5 are in sliding contact with the outer surfaces of the respective rail vertical plates 14.

In the figure, numeral 17 indicates running wheels of the monorail vehicle 12.

Therefore, the rail vertical plate 16 is controlled by the guide wheel 16.
By pressing from the outside with a force Q, the bottom plate 11a of the track girder 11 is restrained from expanding downward due to the load P from the running wheels 17, and as a result, the bottom plate 11b of the track girder 11 This makes it possible to significantly reduce the bending moment generated at the intersection point A between the base plate 11a and the bottom plate 11a. (See Figure 4) Furthermore, by disposing the guide ring 16 outside the track girder 11, the width of the track girder 11 is reduced,
The box girder shape is miniaturized.
