MINE SPECIAL CONVEYER Russian patent published in 2000 - IPC

FIELD: mine hoisting plants for selective haulage of minerals, enclosing rocks and materials over steep vertical shafts including deep and ultradeep mines without use of pulling units with load carriers, propelling devices along closed or interrupted way with intermittent or continuous delivery system. SUBSTANCE: mine special conveyer includes guides with curved sections rigidly mounted on buttons of mine shaft equipment. Guides with curved sections are installed for transferring over them of connected with one another units with suspended on axles freely and symmetrically two load carrying members on each axle with gear wheels for provision of selective transferring of load. Conveyer also has distributed linear hydraulic drive. Axles of conveyer units directly move on internal parts of bearings installed on both ends of axles and including inner races and reinforced cages with balls or rollers, on unfolded outer races of bearings in the form of troughs presenting rigid guides over which conveyer units are moved. Couplings between unit axles are supported on hinges on both sides. Conveyer is loaded from bins on horizon and unloaded on ground surface selectively in places where racks are installed. Conveyer eliminates multistage haulage in step opening of sections of mine mineral reserves. EFFECT: higher efficiency. 5 dwg
