Description
(54) МЕХАНИЗИРОВАННАЯ КРЕПЬ СОПРЯЖЕНИЯ ЛАВЫ СО ШТРЕКОМ(54) MECHANIZED STRIP OF LAVA STRESSING WITH STRETCH
редвижки1перемеа1аютс базова балка 1, т га 2 и продольна балка 3. На новом месте эту балку снова распирают гидростойкой 17. Во врем передвижки поперечные балки 4 и 5 занимают положение, за-The shafts 1 are shifted by the base beam 1, tons of hectare 2 and the longitudinal beam 3. At the new place, this beam is again burst with a hydroresistant 17.
данное пазами 11 и 12 в продольной балке . Передвижку оснований 13 и 14 гидростоек 6 и 7 про 13вод т домкратами 15 и 16, независимо от передвижки поперечных балок 4 и 5. При передвижке поперечныхThis grooves 11 and 12 in the longitudinal beam. The shifting of the bases 13 and 14 of the hydraulic rails 6 and 7 about 13 leads and the jacks 15 and 16, regardless of the shifting of the transverse beams 4 and 5. When shifting the transverse beams
:балок и оснований силовые опоры поворачиваютс относительно вертикального положени .: beams and bases, the power supports rotate relative to the vertical position.
Пред мет изобретени Present Invention
Механизированна крепь сопр жени лавы со штреком, включающа основание, соединенное силовыми домкратами с базоMechanized lining of the lava interface with a drift, including the base connected by power jacks from the base
вой балкой лавной крепи, и перекрытие, состо щее из продольной и поперечных балок , опирающихс на гидростойки, отличающа с тем, что, с целью обеспечени поддержани кровли выработкиwith a longitudinal and transverse beam, supported by hydraulic legs, characterized in that, in order to ensure the maintenance of the roof,
в месте сопр жени лавы со штреком, продольна балка снабжена опорным элементом и кронштейном, который с помощью т ги шарнирно соединен с торцом базовой балки.at the point of interface of the lava with a drift, the longitudinal beam is provided with a support element and a bracket that is hinged to the end of the base beam by means of a cable.
