Abstract
Изобретение относитс к горному делу и м. б. использовано дл поддержани выработок. Цель - повышение эффективности поддержани выработки в неустойчивых породах путем снижени расслоени пород на ее контуре. Устройство состоит из временной крепи (ВК) 2 и опережающей крепи. Последн содержит направл ющую 1, козырьки 5, соединительные звень 3, 4, домкрат 6 распора и боковые ограждени 7. Козырьки 5 соединены с головной секцией ВК 2 шарнирно. Каждое звено 3, 4 св зано шарнирно с головной секцией ВК 2 и направл ющей 1, котора имеет форму выработки и наклонена в сторону забо выработки с возможностью поддержани концов козырьков 5. Домкрат 6 служит дл распора направл ющей 1, дл чего он одним концом шарнирно закреплен на головной секции ВК 2, а другим - на соединительном звене 4. 3 ил. § (ЛThis invention relates to mining, and b. used to maintain workings. The goal is to increase the efficiency of maintaining production in unstable rocks by reducing the stratification of rocks on its contour. The device consists of a temporary lining (VK) 2 and advanced lining. The latter comprises a guide 1, peaks 5, connecting links 3, 4, jack 6 thrust and lateral barriers 7. Peaks 5 are connected to the head section VK 2 pivotally. Each link 3, 4 is pivotally connected to the head section VK 2 and guide 1, which has the shape of development and is tilted towards the bottom of production with the possibility of supporting the ends of the visors 5. Jack 6 serves to spread the guide 1, for which it is hinged at one end fixed on the head section of the VK 2, and the other on the connecting link 4. 3 Il. § (L
