Description

исходное транспортное положение вдоль стоики .initial transport position along the stoics.

Предлагаема  индивидуальна  гидравлическа  крепь быть выполнена как с гидростойками внешнего питани , так и с насосной группой.The offered individual hydraulic lining can be performed both with external hydraulic racks and with the pump group.

Крепь может эффективно примен тьс  при выемке пластов со слабой непосредственной кровлей. Это достигаетс  за счет максимального перекрыти  кровли широкополочными верхн ками.The support can be effectively applied when excavating layers with a weak direct roof. This is achieved by maximizing the overlapping of the roof by wide-top caps.

Предмет изобретени Subject invention

Индивидуальна  гидравлическа  крепь очистных забоев, включаюш,а  корпус с загрузочно-разгрузочным устройством и выдвижную часть с насадкой и верхн ками, отличающа с  тем, что, с целью снижени  трудоемкости креплени , выдвижна  часть снабжена сферической опорой с проушинами и подпружиненной телескопической направл юш.ей, которые с помош;ью шарнирных рычагов через пазообразные отверсти  соединены с верхн ками .The individual hydraulic support of the cleaning faces includes the case with the loading and unloading device and the sliding part with the nozzle and tops, characterized in that in order to reduce the labor intensity of the attachment, the sliding part is provided with a spherical support with eyelets and a spring-loaded telescopic direction which with the help of the hinge arms through the slot-like openings are connected to the tops.
