Valve for adjusting pressure of working fluid,mainly for hydraulic cylinders of mine support sections

Control valves, in the housing bore of which at least one slide rod with a slide piston working as a valve-closing body is arranged in a longitudinally displaceable manner, are provided for controlling hydraulic thrust-piston mechanisms on underground self-advancing supports. A problem here is the fact that a control valve of this type is also to work free of leaks, with small control forces and with relatively high flow rates in a water hydraulic system and with a long service life of the seals. The valve therefore has sleeves surrounding the slide rod on both sides of the slide piston. The sleeves are guided in the housing bore while forming a passage and pass over the allocated piston seals upon adjustment of the slide rod into the open position, so that the piston seals are masked against the hydraulic flow.

Method for operating the mining machine for coal mining in the underground coal face of a coal mine

Method for operating a mining machine for coal mining in the underground coal face of a coal mine. The plurality of timbering and walling units (1-18) in longwall face length as well as the cutting machine (21), which can be moved along the coal impact, are automatically or semi-automatically controlled so that the setpoint cross section is determined as drive-through model (38) of the required transit cross-section, which the mining machine requires, for each face cross section along the route of the mining machine and stored in the memory of the face control device. The actual passage cross section is determined in each face cross-section and, including the reference points of the measurement, is superimposed in the face control device to the stored drive-through model. The face control device transmits a signal, which is processable in the sense of the movement clearance, to the operating control of the mining machine as a function thereof that the stored drive-through model fits into the determined actual cross-section without excess at the reference points of the measurement. In addition, condition variables are determined which are not taken into account in the drive-through model. The drive-through model is defined by the contour (contour model) which circumscribes the required passage cross-section as a contour or as a surface. Electronic cameras (36) can serve to detect the actual image data, which are suspended in certain intervals along the face.

Face equipment with cable levelling units laid between downhole conveyor and frames of shield support

FIELD: mining. SUBSTANCE: invention relates to mechanized support used with downhole equipment for working in continuous development system. Proposed is face equipment for mechanical production in continuous development system, primarily in underground coal mines with face conveyer (17) located along front of works in bottom, with possibility of movement along face conveyor (17) by production mechanism (18) and frame (10) of shield support secured at angle to face conveyor (17). At that, for determination of height of opening of bottom-hole space in area of face conveyor (17) on separate frames (10) of shield support between downhole conveyor (17) and at least one basic component of frame (10) of movable shield is laid hose level (21) with hose filled with fluid (22), and at least on one end of hose (22) there is pressure sensor (23, 24). At that, in addition to account of longitudinal and/or transverse inclination of face conveyor (17) and basic component of frame (10) of movable shield when determining height of face on bottom-hole conveyor (17) and having end hose level basic component of frame (10) of shield support there is at least in two axes of rotation relative to horizontal device (25, 26) for measuring inclination. At that, pressure sensor (23, 24) and inclination measuring device (25, 26) are connected with data processing and control device. EFFECT: simplified determination of height of opening of bottom-hole space. 21 cl, 6 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (51) МПК E21D 23/16 (13) 2 586 991 C2 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ 2014139143/03, 02.04.2012 (24) Дата начала отсчета срока действия патента: 02.04.2012 (72) Автор(ы): ЮНКЕР Мартин (DE), МОЦАР Армин (DE) (73) Патентообладатель(и): РАГ АКЦИЕНГЕЗЕЛЬШАФТ (DE) (43) Дата публикации заявки: 27.05.2016 Бюл. № 15 R U Приоритет(ы): (22) Дата подачи заявки: 02.04.2012 (45) Опубликовано: 10.06.2016 Бюл. № 16 (85) Дата ...

Electrohydraulic control device

FIELD: mine roof supports for step-by-step movement, particularly hydraulic or pneumatic features thereof. SUBSTANCE: control device comprises valve block and executive mechanisms installed in the block. The executive mechanisms are united in several groups and are electrically activated. The executive mechanisms switch-on hydraulic valve members of several distribution valves. Device also has communication panel including electric and/or electronic circuit. All executive mechanisms are linked to the electric and/or electronic circuit through plug-in connections. The commutation panel is fastened to control device and installed on case-shaped body section detachably connected to the valve block. Plug-in connection members are arranged inside the case. Plug-in connection member pattern corresponds to executive mechanism location on valve block. EFFECT: increased reliability and decreased time for executive mechanisms of distribution valve connection. 18 cl, 4 dwg ÐÎÑÑÈÉÑÊÀß ÔÅÄÅÐÀÖÈß (19) RU (11) 2 302 530 (13) C2 (51) ÌÏÊ E21D 23/16 (2006.01) G01V 5/12 (2006.01) ÔÅÄÅÐÀËÜÍÀß ÑËÓÆÁÀ ÏÎ ÈÍÒÅËËÅÊÒÓÀËÜÍÎÉ ÑÎÁÑÒÂÅÍÍÎÑÒÈ, ÏÀÒÅÍÒÀÌ È ÒÎÂÀÐÍÛÌ ÇÍÀÊÀÌ (12) ÎÏÈÑÀÍÈÅ ÈÇÎÁÐÅÒÅÍÈß Ê ÏÀÒÅÍÒÓ (21), (22) Çà âêà: 2003110161/03, 09.04.2003 (30) Êîíâåíöèîííûé ïðèîðèòåò: 10.04.2002 (ïï.1-18) DE 10215576.3 (73) Ïàòåíòîîáëàäàòåëü(è): ÄÁÒ ÃÌÁÕ (DE) (43) Äàòà ïóáëèêàöèè çà âêè: 20.11.2004 R U (24) Äàòà íà÷àëà îòñ÷åòà ñðîêà äåéñòâè ïàòåíòà: 09.04.2003 (72) Àâòîð(û): ÌÓÍÄÐÈ Ñåáàñòü í Ìàðè (DE), ÒÈ×ÅÐÒ Éåíñ (DE), ÇÓÈËÜÌÀÍÍ Ôðàíö-Õàéíðèõ (DE) (45) Îïóáëèêîâàíî: 10.07.2007 Áþë. ¹ 19 2 3 0 2 5 3 0 (56) Ñïèñîê äîêóìåíòîâ, öèòèðîâàííûõ â îò÷åòå î ïîèñêå: DE 19751007 À1, 20.05.1999.
