Description
Крепь устанавливаетс у выхода лавы на штрек и распираетс . При этом ры;чаги 4 обеих секций упираютс в ночву штрека. По мере выемки угл крепь передвигают, дл чего снимают распор с одной из секций и включают домкрат 5. Усилие домкрата 5 передаетс на т ги 6 и присоединенные к ним рычаги 4. Момент, образоваНный двигательным усилием домкрата 5, поворачивает рычаги 4 до упора в ограничители 7. Рычаги 4 неподвижной секции упираютс в почву и на них приходитс двигательное усилие домкрата, а рычаги 4 передвигаемой секции поворачиваютс этим же усилием в нерабочее положение и ие преп тствуют передвижению . Таким образом, дл повышени усили сцеплени секций крепи с боковыми породами используетс усилие одного домкрата передвижени .The support is installed at the exit of the lava on the drift and spreads. In this case, the chags 4 of both sections abut the drift overnight. As the coal is dredged, the lining is moved, for which the strut is removed from one of the sections and the jack 5 is turned on. The force of the jack 5 is transmitted to the rods 6 and the levers 4 attached to them. 7. The levers 4 of the stationary section abut the soil and on them the motive force of the jack falls, and the levers 4 of the movable section turn with the same force into the non-working position and do not impede movement. Thus, to increase the adhesion force of the support sections to the side rocks, the force of one jack is used to move.
При верхнем расположени домкрата рычаги устанавливаютс на верхн ках с возможностью поворота, а к ним эксцентрично и шарнирНо креп тс т ги, присоединенные к концам домкрата.At the top location of the jack, the levers are mounted on the tops with the possibility of rotation, and to them are eccentric and hinged arms attached to the ends of the jack.
Крепь имеет простую конструкцию с одним домкратом передвижки, надежна в работе , что предотвращает аварийные ситуации .The support has a simple design with one shifter jack, reliable in operation, which prevents emergencies.
