  • Patent number: 11938974
    Abstract: A series-parallel monorail hoist based on an oil-electric hybrid power and a controlling method thereof. The monorail hoist includes a cabin, a hydraulic driving system, a lifting beam, a gear track driving and energy storage system, and a speed adaptive control system connected in series with each other and travelling on a track. The monorail hoist is capable of implementing an independent drive by an electric motor or a diesel engine in an endurance mode, a hybrid drive of the electric motor and the diesel engine in a transportation mode, and a hybrid drive of the diesel engine and a flywheel energy storage system in a climbing mode, according to different operating conditions that include conditions of an upslope, a downslope and a load. Power requirements for the monorail hoist under various operating conditions are satisfied, and the excess energy is recovered during the process of travelling.

  • Publication number: 20240043247
    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.
