Description
I при помощи шарового соединени 9. При таком креплении выдвил ных элементов 1 в корпусе щита сохран етс параллельное по отношению к плоскости ножевого листа положение их и они гарантируютс от перекосов и заклинивани . Шарнирное же кренление корпуса гидродомкрата выдвилсного элемента н его штока обеспечивает равномерное раснределеиие усилий на его выдвижение без перекосов от неравномерной нагрузки горного давлени на рабочую поверхность выдвижного элемента.I using a spherical joint 9. With such an attachment, the extrusion elements 1 in the shield body maintain their position parallel to the plane of the knife sheet and they are guaranteed against distortions and seizure. The hinged roll of the body of the hydraulic cylinder of the extension element and its rod ensures uniform distribution of efforts for its extension without distortions from the uneven load of the rock pressure on the working surface of the sliding element.
Выдвижение и уборка выдвижных элементов производитс ручным управлением подачи рабочей жидкости в ту или иную полость гндродомкратов выдвижени 7. При этом выдвижные элементы 1 опираютс на опорные элементы , которые раздвигаютс .The extension and cleaning of the sliding elements is carried out by manually controlling the supply of working fluid to one or the other cavity of the hydraulic jacks of the extension 7. The sliding elements 1 are supported on the supporting elements, which move apart.
