Abstract: The disclosure discloses a device for detecting idling time of a brake shoe of a monorail hoist and a detection method thereof. The device includes a contact detection unit, a common end roller unit, an idling time detection unit and detection lines. The contact detection unit installed on a brake of the monorail hoist includes a tube in connection with the brake shoe. The common end roller unit is installed on a frame of the monorail hoist and corresponds to a travelling track. A metal probe corresponding to the travelling track is arranged inside the tube. A limiting bolt corresponding to a raised cylindrical block formed on the metal probe is formed on an inner side wall of the tube. The metal probe is contactable with the travelling track or the limiting bolt when the brake shoe brakes.

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.

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.
