MECHANISM FOR DISPLACEMENT OF SECTIONS OF SUPPORT AND CONVEYER Russian patent published in 2003 - IPC

FIELD: mining industry, powered complexes for underground mining of mineral wealth. SUBSTANCE: mechanism for displacement of sections of support and conveyer includes hydraulic displacement jack coupled to section of support and pusher to which link with eccentric is hinged with the help of axle placed vertically. Eccentric is mounted for contact with surface of conveyer. Link also has groove tied to section of conveyer by means of axle placed in same groove. Groove in link is cut longitudinally, axle on section of conveyer is positioned vertically, eccentric is located by conveyer edge of link asymmetrically with reference to horizontal symmetry plane of link. Link is mounted for plane-parallel motion in process of wave-like displacement of flight of conveyer. Link with eccentric is mounted for change of its position with the aid of turn through 180 degrees around symmetry axis of link. Washer can be put on axle of pusher placed vertically for contact with horizontal surfaces of pusher and link. EFFECT: prevented failure of mechanism in process of wave-like advance of conveyer on to face, capability of adjustment of effort and other power parameters. 1 cl, 6 dwg
