Description
Гидравлические стойки 3 крайних секции комплекта крепи укреплены на нижней части 4 ограждени и в исходном положений строенных секций наход тс в одной плоскости с гидравлической стойкой 3 средней секции (на чертеже не показано).The hydraulic legs 3 of the extreme sections of the set of supports are fixed on the lower part 4 of the fence and in the initial positions of the built sections are in the same plane with the hydraulic stand 3 of the middle section (not shown in the drawing).
Работа крепи осуществл етс следующимThe work of the lining is carried out as follows
образом.in a way.
При изменении мощности пласта выдвижна вертикальна стенки 9, соединенна с перекрыти ми 2 крайних секций комплекта посредством верхней части ограждени 5, предохран ет рабочее пространство крепи от обрущенных пород, а возможность поворота упом нутых перекрытий совместно с верхней частью 5 ограждени относительно щарнира 10 в случае неровной кровли повыщает эффективность ее поддержани .When the reservoir thickness changes, the extendable vertical wall 9 connected to the overlaps of the two extreme sections of the set by means of the upper part of the fence 5 protects the working space of the support from collapsed rocks, and the possibility of rotation of the said overlaps together with the upper part 5 of the fence relative to the hinge 10 roofing increases the efficiency of its maintenance.
Предмет изобретени Subject invention
Шахтна механизированна крепь, состо ща из комплектов, каждый из которых состоит из трех секций, имеющих основание, перекрытие , гидростойку и ограждение, выполненное на всю щирину комплекта и состо щее из нижней и верхней частей, щарнирно закрепленных соответственно на основани хThe mine mechanized lining, consisting of sets, each of which consists of three sections, having a base, an overlap, a hydrorack and a fence made over the entire width of the set and consisting of the lower and upper parts, hinged respectively on the bases
крайних секций и на их перекрыти х, отличающа с тем, что, с целью повыщени надежности защиты рабочего пространства крепи от обрущенных пород, между нижней и верхней част ми ограждени размещена вертикальна стенка, одна сторона которой посредством шарнира соединена с верхней частью , а друга с помощью щарнирно-рычажной св зи - с нижней.extreme sections and on their overlaps, characterized in that, in order to increase the reliability of protection of the working space of the lining against the collapsed rocks, a vertical wall is placed between the lower and upper parts of the fence, one side of which is connected to the upper part by means of a hinge. using a hinged link - from the bottom.
