Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a power supply rail for a monorail turnout on a monorail track, and particularly to a power supply rail for a monorail turnout that is suitable when the branching angle is large.

[Background of the idea]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A power supply rail in a conventional monorail turnout will be explained with reference to FIGS. 1 to 6. FIG. 1 is a plan view of the turnout, and FIG. 2 is a side view of the turnout.
In the figure, a bogie 2 and wheels 3 are fixed to a girder 1, and the bogie 4 is provided with a center pin 5 that can pivot when switching the turnout. The foundation 6 includes the girder 1,
A rail 7 that supports the trolley 2 is fixed. The branch girder is constructed by articulating a plurality of the girders 1 by means of T-shaped pin joints 8 so that they can be bent horizontally and vertically. Further, the branching girder can bend the girder 1 in an articulated manner by a drive device and change the trajectory by a set distance to switch the trajectory to two or three lines. Power supply rails 9 are provided on both sides of the girder 1. FIG. 3 is a sectional view of the power supply rail 9, in which the power supply rail 9 is fixed by a bracket 10 and an insulator 11 attached to the girder 1.

Next, FIGS. 4 and 5 are a side view and a plan view of the joint portion of the feeder rail, and FIG. 6 is a plan view of the joint portion in a converted state. A joint 12 is provided, and the branch girder is T.
It is designed so that there is no interference when turning around the shaped pin joint 8.

According to such a configuration, when the branch girder is converted around the T-shaped pin joint 8, the distance between the joints 12 becomes wider on the outside of the center of rotation and narrower on the inside. Therefore, the joint 12 of the power supply rail 9 is configured to have a gap. Further, a bond wire 13 is provided on the upper part of the joint 12 in order to make an electrical connection at the joint portion. In the above-mentioned conversion state, when the angle increases, the gaps between the joints 12 become larger, so the gaps are made larger. However, this gap has a limit, and if it is not kept within the length of the collector shoe of the current collector installed in the vehicle, the collector shoe will get stuck in the gap.
The impact damages the collector shoe, the insulator 11, etc. However, it is difficult to make the collector shoe too long due to the configuration of the current collector, and the gap cannot be made too large. but,
Since it is desired to reduce the number of girders 1 by increasing the branching angle of the branch girder as much as possible, there is a drawback that there is a risk that the collector shoe may get stuck in the gap due to aging.

[Purpose of invention]

The purpose of this invention is to simplify the structure without adding any parts to the joint part of the power supply rail.
Another object of the present invention is to provide a power supply rail for a monorail turnout in which the gap between the joint portions can be minimized and the collector shoe can smoothly slide even if the turning angle of the turnout girder becomes large.

[Summary of the idea]

The present invention is a feed rail joint of a monorail turnout that is installed on the side of a plurality of girders that are rotatably connected around a vertical axis and a horizontal axis. one of the opposing surfaces is formed in a convex arc shape centered on the swinging vertical axis of the girder, and the other opposing surface is formed in a concave arc shape centered around the swinging vertical axis, and It is characterized in that a gap is provided between the opposing surfaces to prevent interference when the girder turns.

[Example of idea]

Hereinafter, one embodiment of the feeder rail according to the present invention will be described as part 7.
This will be explained with reference to the drawings and FIG. FIG. 7 is a plan view of the power supply rail joint, and FIG. 8 is a plan view of the power supply rail joint at the time of digit change. In the figure, 14, 15
are joints of the feeder rails, each of which has opposite ends cut out in the shape of an arc having the same center as the T-shaped pin joint 8 of each girder 1. The joint 14 is formed into a convex shape, and the joint 15 is formed into a concave arc shape, and a gap δ is provided between them so that they do not interfere with each other when the girder 1 turns. The power supply rail 9' having the joints 14 and 15 formed thereon is fixed to the girder 1 via a bracket and an insulator.

In such a configuration, when the girder 1 is operated by the trolley, the T-shaped pin joint 8 allows the respective swings between the girders 1, and the feed rails 9', 9' The gap δ allows for relative displacement due to rocking between the girders 1. During such a conversion operation, the opposing surfaces between the feed rails 9', 9' are each formed in an arc shape with one convex and the other concave,
Since each center coincides with the vertical axis of swing of the girder 1, that is, the vertical axis of the T-shaped pin joint, the gap δ does not change with the switching operation.

Incidentally, the installation positions of the feeder rails 9', 9' on the opposing surfaces are shifted in the longitudinal direction of each girder 1 from the connection points of the T-shaped pin joints of each girder 1.

According to such a configuration, the gap between the power supply rails 9', 9' does not widen when the girder 1 is in the converted state, and the collector shoe provided in the current collector does not get stuck in the gap. Therefore, it is possible to prevent damage to the current collector or the power supply rails 9', 9' due to the collector shoe getting stuck between the power supply rails 9', 9'. Further, even if the turning angle of the girder 1 is increased, the same effect can be achieved.

Furthermore, there is no need to provide any special member between the power supply rails 9', 9', the structure can be simplified, and there is no risk of an increase in the number of parts.

[Effect of idea]

As explained above, according to the present invention, the structure can be simplified without adding any members to the joint part of the feeder rail, and even if the turning angle of the branch girder becomes large, the gap at the joint part can be minimized. The holding collector shoe can slide smoothly.
