MINE CONVEYER Russian patent published in 1998 - IPC

FIELD: mining industry. SUBSTANCE: this relates to mine hoisting devices for selective transportation of minerals, mineral-bearing rock, and materials through steep and vertical mine shafts without use of hoisting ropes, pulling members with load carriers moving along closed circuit with continuous delivery of load. Mine conveyer has guide members with curvilinear sections rigidly mounted on cross-members of reinforcement, installed for possible moving along them on rollers embracing guide members at two opposite sides of interconnected links with load-carrying means with their bottoms freely suspended on axles and provided with gear wheels for selective movement of load, and with drives in the form of hydraulic cylinders. Pivotally mounted and symmetrically located on link axles are two load-carrying means. Link axles are rigidly installed in cheeks on which rollers are mounted. Hydraulic cylinders are pivotally installed and located in middle part of axle successively along guide members on reinforcement of mine workings. Chain links can move along both isolated and continuous lines. Movement is effected by hydraulic power cylinders which by pads of their rods displace links: push or release depending on their location in general conveyer track and preset program of operation. EFFECT: high efficiency. 3 dwg
