Abstract
A system for obtaining mechanical power from a driven belt conveyor which services a remote area such as a coal mine where delivering electrical power is difficult and/or hazardous. The system includes apparatus selectively driven by the return flight of the mined material conveyor belt to provide mechanical driving power to an auxiliary device, such as a pump. A pair of driveable rollers are coupled together on the same side of the belt and a tensioning roller, for urging the conveyor belt into driving engagement with the driveable rollers, is adjustably positioned on the opposite side of the belt.
Claims10
A system for obtaining mechanical power in a mine serviced by conveyor structure including a driven conveyor belt with a flight for removing mined material and a return flight, the system comprising,
- power take-off apparatus with means for positioning such apparatus in contiguous relationship to the conveyor structure,
- such power take-off apparatus including
- driveable roller means,
- framework structure for positioning the driveable roller means so as to be driven by the return flight of the conveyor belt,
- belt tensioning means for selectively urging such conveyor belt to drive such roller means, and
- a power shaft driven in response to rotation of such roller means for delivering mechanical drive power to auxiliary equipment.
