Изобретение относитс к добыче угл подземным способом, а именно к механизации разработки угольных пластов по падению.The invention relates to the extraction of coal by the underground method, namely to the mechanization of the development of coal seams in the fall.
Известны механизированные крепи дл отработки пологопадающих пластов угл в комплексе с выемочным комбайном и конвейером .Known mechanized lining for mining gently dipping layers of coal in combination with a mining combine and conveyor.
Предлагаема крепь отличаетс от известных тем, что секторный оградительный элемент размещен внутри сплошного ограждени и соединен с ним шарниром, а с перекрытием секции св зан посредством т ги. Такое выполнение крепи повышает надежность ее работы по падению пласта.The proposed lining differs from the known ones in that the sector protective element is placed inside a solid fence and is connected to it by a hinge, and is connected with a tie with the overlapping of the section. This embodiment of the lining increases the reliability of its work on the fall of the reservoir.
На чертеже показано предлагаемое устройство , поперечный разрез.The drawing shows the proposed device, the cross-section.
Оно состоит из отдельных шарнирно соединенных секций, кажда из которых имеет раму 1, на которой установлено сплошное ограждение 2. Секторный оградительный элемент 3 размещен внутри сплошного ограждени 2 и соединен с ним шарниром 4, а с перекрытием 5 - посредством т ги 6. Перекрытие 5 соединено гидростойками 7 с основанием 8. Передвигаетс крепь на забой гидродомкратами 9 и 10. При выдвижении секции крепи на забой перекрытие 5 посредством т ги 6 перемеш ает секторный оградительный элемени 3, который, поворачива сь, выходитIt consists of separate pivotally connected sections, each of which has a frame 1, on which a continuous fence 2 is installed. The sectorial protective element 3 is placed inside the continuous fence 2 and connected to it by a hinge 4, and with overlap 5 - by means of ty 6. Overlapping 5 Hydraulic supports 7 are connected to the base 8. The support is moved to the bottom by hydraulic jacks 9 and 10. When the section of the support is extended to the bottom, the overlap 5 by means of the plug 6 mixes the sector protective element 3, which turns
из сплошного ограждени 2 и нерекрывает увеличивающеес пространство между перекрытием и сплошным ограждением. При выдвижении на забой рам 1, образующих базовую балку, секторный оградительный элементfrom the solid fence 2 and the non-overlapping increasing space between the overlap and the solid fence. When extending to the bottom of the frame 1, forming the base beam, the sector protective element
3, поворачива сь, входит внутрь сплошного ограждени .3, turning, enters inside the solid fence.
Предмет изобретени Subject invention
Механизированна крепь дл работы по падению пласта, включающа сплошное ограждение и секции, кажда из которых включает раму, перекрытие, гидростойки, гидродомкраты передвижени и секторный оградительный элемент, отличающа с тем, что, с целью повышени надежности работы крепи , секторный оградительный элемент размещен внутри сплошного ограждени и соединен с ним шарниром, а с перекрытием секцииMechanized roof support for the dip, which includes a solid fence and sections, each of which includes a frame, ceiling, hydraulic rails, movement hydraulic jacks and a sector protective element, characterized in that, in order to improve the reliability of the support, the sector protective element is placed inside the solid fencing and connected to it by a hinge, and with overlapping section
