Description
Изобретение относитс к горной промышленности и может быть использовано на добычных участках угольных шахт дл борьбы с пылью, образующейс при передвижке секций механизированной .The invention relates to the mining industry and can be used in the mining areas of coal mines to combat the dust generated during the movement of mechanized sections.
По основному авт. св. № 900029 известна система пылеподавлени механизированной крепи, включающа забойный водопровод, гидромагистрали с нагнетательными и всасывающими клапанами , оросител ми и гидроцилиндрами ,,корпусы и штоки которых жестко .закреплены на смежных секци х крепи, а поршневые и штоковые полости соединены гидромагистрал ми с забойным водопроводом и оросител ми 1.According to the main author. St. No. 900029 is a known dust suppression system for mechanized roof supports, including a bottom-hole water supply system, hydraulic lines with injection systems and suction valves, irrigators and hydraulic cylinders, housings and rods of which are rigidly fixed on adjacent lining sections, and piston and rod cavities are connected by a main line and a single center and a single main axis. sprinklers 1.
Однако.при эксплуатации механизированных крепей часто мен етс рассто ние между секци ми и при жест.кой св зи корпусов гидроцилиндров и штоков с секци ми может происходить отрыв от секции корпуса гидроцилиндра или штока, т.е. система недостаточно , надежна.However, when operating mechanized supports, the distance between sections often changes and during rigid communication between the housings of hydraulic cylinders and rods with sections, separation from the section of the hydraulic cylinder housing or the rod, i.e., can occur. The system is not enough, reliable.
Цель изобретени - повышение надежности работы и эффективности пылеподавлени .The purpose of the invention is to improve the reliability and efficiency of dust suppression.
Цель достигаетс т.ем, что поршни гипооцилиндров снабжены дополнительными штоками, расположенными противоположно основным штокам, при этом оба штока каждого гидроцилиндра соединены с одной и той же секцией механизированной крепи посредством гибкой св зи.The goal is achieved by the fact that the pistons of the hypo-cylinders are provided with additional rods located opposite to the main rods, while both rods of each hydraulic cylinder are connected to the same mechanized support section by means of a flexible connection.
На чертеже приведена принципиальна схема предлагаемой системы пылеподавлени .The drawing is a schematic diagram of the proposed dust suppression system.

Система включает забойный водопровод 1, гидроцилиндры 2 и встроенные в перекрыти секции крепи оросители 3, направленные в межсекционное пространство . Гидроцилиндр 2, жестко за15 крепленный на секции 4 крепи, св зан с основным 5 и дополнительным 6 штоками через гибкие св зи 7 и 8 с секцией 9 крепи. Точно также гидроцилиндр 2, закрепленный на секции The system includes bottomhole water supply system 1, hydraulic cylinders 2, and sprinklers 3, which are built into the overlapping sections, and directed into the intersectional space. The hydraulic cylinder 2, rigidly fastened 15 fixed to section 4 of the support, is connected to the main 5 and additional 6 rods via flexible couplings 7 and 8 to section 9 of the support. Similarly, the hydraulic cylinder 2, mounted on the section
20 10 крепи, св зан с секцией 4. Поршень 11 раздел ет гидроцилиндр на две полости А и Б одинакового сечени . Оросители 3 св заны с обеими полост ми гидроцилиндров 2 через 2 гидромагистрали 12 и 13 с обратными клапанами 14 и 15. Подача жидкости из забойного водопровода осуществл етс к обеим полост м гидроцилиндра по магистрал м 16 и 17, оборудован30 ным всасывающими клапанами 18 и 19.20 10, fixed to section 4. The piston 11 divides the hydraulic cylinder into two cavities A and B of the same section. The sprinklers 3 are connected to both cavities of the hydraulic cylinders 2 through 2 hydraulic lines 12 and 13 with non-return valves 14 and 15. Fluid supply from the bottomhole pipeline is carried out to both cavities of the hydraulic cylinder through lines 16 and 17, equipped with suction valves 18 and 19.
