Abstract
Изобретение относитс к горному оборудованию . Цель- повышение эксплуатационных возможностей за счет повышени надежности работы. Механизированна крепь включает основание 1, выполненное из трех лыж, перекрытие 5 с козырьком 6, забойные гидростойки (ГС) 8 и завальную ГС. Кажда из ГС 8 соединена с перекрытием 5 и боковыми лыжами, а завальна ГС опираетс на среднюю лыжу. В верхней части посредством шарнира 10 ГС соединена с поворотной опорой 11. Перекрытие 5 выполнено с отверстием, выполненным по продольной оси крепи. Забойные концы боковых лыж соединены поперечной траверсой 13, к которой прикреплен конец гидродомкрата передвижки. Распор крепи между кровлей и почвой осуществл етс ГС 8 и 9, воздейству на перекрытие 5, поворотную опору 11 и лыжи. 7 ил.The invention relates to mining equipment. The goal is to increase operational capabilities by increasing reliability. Mechanized lining includes a base 1, made of three skis, overlapping 5 with a visor 6, downhole hydraulic racks (HS) 8 and a bumper HS. Each of the HS 8 is connected to an overlap of 5 and side skis, and the bulkhead GS relies on an average ski. In the upper part by means of a hinge 10 GS connected with a rotary support 11. Overlap 5 is made with a hole made along the longitudinal axis of the support. The downhole ends of the side skis are connected by a transverse beam 13, to which the end of the shifter jack is attached. The lining between the roof and the ground is made by HS 8 and 9, affecting the overlap 5, the pivot bearing 11 and the skis. 7 il.
