  • 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.

  • Publication number: 20230348238
    Abstract: The present disclosure belongs to the technical field of mining equipment, and in particular related to an automatic driving system of a monorail hoist driven based on a digital twin and a method thereof. The system includes a railroad switch sensor module, a positioning system module, a data transferring system, an intelligent control system, a digital twin system and an automatic driving module. The railroad switch sensor module is configured to sense the connection-position state of a movable track in a monorail hoist railroad switch track. The data transferring system is configured to transmit the data on the surface and underground. A bidirectional transmission is performed between the intelligent control system and the railroad switch sensor module, a bidirectional transmission is performed between the intelligent control system and the positioning system module, and a bidirectional transmission is performed between the digital twin system and the intelligent control system.

  • Publication number: 20230303130
    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.

  • Patent number: 11738973
    Abstract: A gear-track-detachable driving device in a monorail crane for a steep slope includes a driving mechanism, a traveling mechanism, a four-bar linkage mechanism, a connection mechanism, a meshing track plate and transition track plates. The driving mechanism includes driving motors, meshing gears, a bearing rod, and a bearing plate. The traveling mechanism includes traveling wheels, clamping wheels, a shell and telescopic struts. The linkage mechanism includes first and second rockers, a linkage, and a cylinder. The connection mechanism includes fixation plates, a connection plate and connection bolts. When the crane travels to the slope front, the cylinder drives the linkage mechanism to send the meshing gears onto the transition track and adjusts the linkage mechanism into a dead point state, and the telescopic struts are locked. After the crane enters the slope, the meshing gears cooperate with the meshing track plate to provide an auxiliary drive for the crane.
