Abstract
Изобретение относится к креплению призабойного очистного пространства механизированнымикрепями при отработке тонких пластов крутого падения. Цель - улучшение направленности, устойчивости и надежности работы. Механизированная крепь содержит четные 1 и нечетные 2 секциикрепи и секции завальных телескопическихограждений. -Секции крепи связаны между собой гидродомкратами 5 передел2 женця и боковыми гидродомкратами 17, шарнирнс закрепленными на гидростойках секций. Одни из секций 7 ограждений прикрепленык перекрытиям и основаниям четныхсекций, Другие секции 8 ограждений имеют на одном из концов телескопическую стойку, с которой соединены раздвижные частиэтих секций 8. Секции 8 связаны с нижележащейчетной секцией 7 гибкой связью. Секции 7 ограждения шарнирно связаны с телескопическими стойками кронштейнами. Секции 8 ограждений связаны с секциями 2 крепи с помощью эластичной сетки и установленногона ней пнэвмобаллонг 15. При передвижкекрепи секции 8 поворачиваются при передвижке четных секций 1 крепи, сжимая пневмобаллон 15, Зазоры между секциями крепи и секциями ограждений позволяют производить поднятие секций крепи в случае их опускания. 7 ил. (Л The invention relates to fastening the bottomhole cleaning space with mechanized supports when mining thin steep layers. The goal is to improve the direction, stability and reliability of work. Mechanized lining contains even 1 and odd 2 sections of fasteners and sections of telescopic fences. -Section of lining are interconnected by hydraulic jacks 5 redistribution 2 women and lateral hydraulic jacks 17, hinges attached to the hydraulic posts of the sections. Some of the sections 7 fences are attached to the floors and bases of even sections, the other sections 8 of the fences have a telescopic rack at one end, to which the sliding parts of these sections 8 are connected. Sections 8 are connected to the underlying flexible section 7. Section 7 fencing pivotally connected with telescopic racks brackets. Sections 8 fences are connected with sections 2 of the lining using an elastic grid and installed a pnevmobalong 15. It moves with lashing section 8 rotates when moving even sections 1 of the lining, squeezing the pneumatic tube 15, the gaps between the lining sections and sections of fences allow raising sections of lining in case of their lowering . 7 il.
