Abstract

A guide track includes a guide rail having a guide groove opened upward in which guide wheels are inserted, and formed with guide surfaces for causing each of the guide wheels to roll at both sides of a traveling course in a width direction; conductor rails that are placed at both sides of an outside of the traveling course in the width direction with respect to the guide groove to perform contact electricity supply by pressing a power collection shoe of a power collector of a track-based vehicle; a first insulator that supports the conductor rails with respect to the guide rail; and insulation plates that are provided at both sides of the conductor rail in the width direction, and are provided in parallel to the conductor rail and in parallel to a pressing direction of the power collection shoe.

First claim

The invention claimed is:

1. A guide track for a track-based vehicle that guides the track-based vehicle to follow a predetermined traveling course by causing a pair of guide wheels in the track-based vehicle to roll, the guide track comprising:
a track main body having a guide groove opened upward in which the guide wheels are inserted, and a pair of guide surfaces for causing the pair of guide wheels to roll at both sides of the predetermined traveling course in a width direction;
a conductor rail that is positioned on at least one side of an outside of the predetermined traveling course in the width direction with respect to the guide groove to perform contact electricity supply by pressing a power collection shoe of a power collector of the track-based vehicle;
a support portion that includes an insulation material and supports the conductor rail with respect to the track main body; and
a protection member serving as an insulation material that is at least on both sides in a width direction or an upper part of a vertical direction of the conductor rail, and is in parallel to the conductor rail and in parallel to a pressing direction of the power collection shoe so as to prevent a short circuit due to contact with the conductor rail in the width direction or the vertical direction,
wherein the support portion includes an accommodation concave portion capable of accommodating the conductor rail,
wherein the conductor rail has concave portions that extend in a front and back direction along the predetermined traveling course, the concave portions being defined on both sides of the conductor rail or on an upper surface of the conductor rail and a lower surface of the conductor rail, respectively,
wherein the accommodation concave portion has convex portions on inner surfaces thereof, the convex portions being at positions corresponding to the concave portions, respectively,
wherein the convex portions are in direct contact with the concave portions, respectively, and
wherein, in a cross-sectional view of the support portion and the conductor rail, gaps are defined at both opposite sides of each of the convex portions.

2. The guide track for a track-based vehicle according to claim 1 , wherein
the accommodation concave portion includes the protection member.

3. The guide track for a track-based vehicle according to claim 1 ,
wherein an inner surface of the accommodation concave portion is in surface contact with a surface of the conductor rail.

4. The guide track for a track-based vehicle according to claim 3 ,
wherein the accommodation concave portion has a U-shape when viewed from a cross section, and has an opening portion which faces outward in the width direction, and
wherein the power collection shoe is pressed to the conductor rail through the opening portion.

5. A transportation system comprising:
the guide track for a track-based vehicle according to claim 1 ; and
the track-based vehicle that is guided by the guide track and runs.

6. The transportation system according to claim 5 , wherein a separation interval of the pair of guide surfaces of the guide track is smaller than a sum of diameters of the guide wheels, and
the guide wheels for the track-based vehicle are positioned so that positions thereof in the front and back direction along the predetermined traveling course are different from each other.

7. A transportation system comprising:
the guide track for a track-based vehicle according to claim 2 ; and
the track-based vehicle that is guided by the guide track and runs.

8. The transportation system according to claim 7 , wherein a separation interval of the pair of guide surfaces of the guide track is smaller than a sum of diameters of the guide wheels, and
the guide wheels for the track-based vehicle are positioned so that positions thereof in the front and back direction along the predetermined traveling course are different from each other.
