CIRCULAR DISTRIBUTION TYPE FRICTION HOISTING SYSTEM FOR ULTRA-DEEP VERTICAL SHAFT

摘要

A circular distribution type friction hoisting system for an ultra-deepvertical shaft is provided.The system includes a friction wheel (130), a left guide wheel (121), a rightguide wheel (151), aleft hoisting container (152), a right hoisting container (152), balance ropes(160), a tensionadjusting system (170), composite wheel sets (141, 142, 143, 144, 145, and146), steel wire ropes(111, 112, 113, 114, 115, and 116), reels (180) and a steel wire rope clip(190), where thecomposite wheel sets (141, 142, 143, 144, 145 and 146) are circularlydistributed around thefriction wheel (130), and tension of the steel wire ropes is adjusted byadjusting locations ofcomposite wheels (141-2, 142-2, 143-2, 144-2, 145-2 and 146-2) in thecomposite wheel sets. Thepresent invention helps reduce bending stress of friction wheel shafts, andresolves a problem thatbending stress of friction wheel shafts of a conventional friction hoistingsystem is excessivelylarge. A conventional container tension balancing device does not need to bearranged, so that aproblem of unbalanced tension caused by a displacement difference betweendifferent steel wireropes and a large self-weight problem caused by the conventional containertension balancingdevice are effectively resolved. Moreover, a location adjusting range of thecomposite wheels islarge, which prevents a problem that an adjusting amplitude of a conventionalhydraulic tensionbalancing device connected to a container is small.
