Abstract
A high-precision positioning system for a monorail hoist in a mine includes two gear carriers symmetrically arranged on both sides of an I-beam track. Each of the gear carriers includes a positioning wheel and a plurality of travelling wheels. The travelling wheels are travelling on an upper end face of a bottom plate of the I-beam track, and the positioning wheel is in engagement transmission with a rack at a lower end of the bottom plate of the I-beam track. The gear carriers include an installation bracket and a connecting seat configured to connect the monorail hoist. The installation bracket includes an inertial measuring unit and a single-chip microcomputer that are electrically connected with each other. The positioning wheel includes a rotation angle sensor and the rotation angle sensor is electrically connected to the single-chip microcomputer. A headstock at both ends of the monorail hoist includes a coordinate updating unit.
