Изобретение относитс к горному делу, конкретно к механизированным креп м очистных забоев.FIELD OF THE INVENTION The invention relates to mining, specifically to mechanized fortifications of cleaning faces.
Известно устройство дл креплени забо , включающее прижимной щит, козырек , телескопическую траверс у, гидродомкрат и штангу 1.A device for fastening the bottom includes a pressure plate, a visor, a telescopic yoke, a hydraulic jack and a barbell 1.
Недостатком известного устройства вл етс .зависимость положени прижимного щита от расположени козырька относительно кровли, и как следствие , его неработоспособность при отсутствии контакта между козьфьком и кровлей.A disadvantage of the known device is the dependence of the position of the pressure plate on the location of the visor relative to the roof, and as a result, its inoperability in the absence of contact between the goat and the roof.
Наиболее близким к изобретению по технической сущности и достигаемо .му результату вл етс перекрытие секции механизированной крепи, включающее верхн к, соединенный с ним шарнирно козырек, забойный прижимной щит, прикерпленный к верхн ку посредством последовательно соединенны друг с другом шарнирных стержн и звена, и гидродомкрат, св занный с верхн ком 2J.The closest to the invention to the technical essence and achievable. My result is the overlapping of the mechanized roof support section, including the upper hinge, the hinged visor connected to it, the bottomhole pressing plate attached to the upper hinge rod and link, and a hydraulic jack. associated with the top 2J.
Недостатком известного перекрыти вл етс неудовлетворительна приспосабливаемость к неровност м забо что обусловлено наличием св зи забойного прижимного щита с козырьком.A disadvantage of the known overlap is the inadequate adaptability to unevenness of the bottom surface, which is due to the presence of a bond of a downhole pressing plate with a visor.
Цель изобретени - повышение производительности перекрыти к неровност м кровли и забо .The purpose of the invention is to improve the performance of the overlap to the unevenness of the roof and bottom.
Поставленна цель достигаетс тем, что шарнирный стержень дополнительно шарнирно соединен с верхн ком посредством водила, к средней части которого прикреплен гидродомкрат.The goal is achieved by the fact that the hinge rod is additionally pivotally connected to the top by means of the carrier, to which the hydraulic jack is attached to the middle part.
На фиг. 1 изображено перекрытие FIG. 1 shows the overlap
o секции крепи в рабочем положении, вид сбоку; на фиг. 2 - то же, в сложенном положении.o lining sections in working position, side view; in fig. 2 - the same, in the folded position.
Перекрытие состоит из козырька 1, шарнирно установленного наверхн ке The overlap consists of a visor 1, pivotally mounted on top
5 2, водила 3 и стержн 4, шарнирно закрепленных на верхн ке и соединенных между собой шарнирн1 1м звеном 5, к свободному концу которого прикреплен забойный прижимной щит 6. К сред0 ней части водила 3 прикреплен гидродомкрат 7, вторым концом соединенный с верхн ком.5 2, carrier 3 and rod 4, hinged at the top and interconnected by hinge 1 with link 5, to the free end of which a downhole pressure shield 6 is attached. To the middle part of the carrier 3 is attached a hydraulic jack 7, with a second end connected to the top com.
