Light rail transport system for bulk materials

InactiveUS20060162608A1Reduce needSmoother rotational transitionRailway tracksRope railwaysTransport systemTransit system
A non-powered, light rail unit train (referred to as Rail-Veyor by the inventor) combination for the transport of bulk materials consisting of a plurality of connected cars open at each end except for the first and last cars, which have end plates. The train forms a long open semi-circular trough and has a flexible flap attached near the front of each car, overlapping the gap between car in front to prevent spillage during operation while allowing articulated movement of the train during transport. The lead car has four flanged wheels and tapered side drive plates at the front of the car for smooth entry into the systems stationary drive stations. The cars that follow each have parallel drive plates on either side of the car that are outside the two flanged wheels that are approximately the same width as the flexible drive tire. Each car has a clevis type hitch at the front and rear with the front clevis hitch connecting to the rear clevis hitch of the car immediately forward. Forward motion is provided by a series of appropriately placed fixed drive stations consisting of drive motors, gear reducers and horizontal flexible drive tires located on either side of the track which can be adjusted to provide sufficient friction on the aforementioned drive plates to transform rotational tire motion to horizontal thrust of the entire train. The motors at each drive station are controlled by use of an A / C inverter and controller whereby said motors are synchronized and both the voltage and frequency can be modified as needed to provide and adjust system operating needs. The flanged wheels are symmetrical to the side drive plates allowing operation in an inverted position which, when four rails are used to encapsulate the wheel outside loop discharge of the bulk material is possible. By using elevated rails, the train can operate in the inverted position as easily as in the convention manner.
