Изобретение относитс «к горному делу и может быть использовано при конструировании Крепи очистных забоев при разработке полезных ископаемых.The invention relates to mining and can be used in the design of a Crepe of clearing faces in the development of minerals.
Известны стойки шахтной крепи, включающие пневматический баллон, соединенный с верхним и нижним основани ми.Shaft support posts are known, including a pneumatic cylinder connected to the upper and lower bases.
В предлагаемой стойке шахтной крепи дл увеличени ее жесткости основани снабжены дисками с фиксаторами угла поворота и шарнирно укрепленными стержн ми, которые расположены наклонно относительно оси стойки.In the proposed shaft support rack, in order to increase its rigidity, the bases are provided with disks with angle-locking clips and hinged rods that are inclined relative to the axis of the rack.
На фиг. 1 изображена предлагаема стойка; на фиг. 2 - вертикальное сечение.FIG. 1 shows the proposed rack; in fig. 2 - vertical section.
Стойка содержит верхнее и нижнее основани 1 и 2, в пазах которых установлены с возможностью скольжени кольца 3 и 4. На основани х и кольцах шарнирно укреплены две системы наклонно расположенных и взаимно перекрещивающихс стержней 5 и 6, образующих коаксиальные гиперболоиды вращени . На основани х 1 и 2 имеютс выступы 7 и 8. Основани снабжены дисками с фиксаторами 9 и 10 угла поворота.The rack contains upper and lower bases 1 and 2, in the grooves of which rings 3 and 4 are mounted with slip. On the bases and rings, two systems of obliquely arranged and mutually intersecting rods 5 and 6 forming coaxial rotation hyperboloids are hinged. On bases 1 and 2 there are protrusions 7 and 8. The bases are equipped with discs with clamps 9 and 10 of the angle of rotation.
Во внутренней полости стойки, образованной дисками и стержн ми, размещен пневмобаллон 11 с вентилем 12.In the internal cavity of the rack formed by the disks and rods, there is a pneumatic air bag 11 with a valve 12.
При повышении давлени в баллоне основани стойки, благодар изменению наклона стержней при взаимном скольжении дисков и колец, раздвигаютс . После достижени требуемого давлени распора крепь фиксируетс в определенном положении с помощью фиксаторов, расположенных на дисках оснований . При этом конструкци обеспечивает воспри тие нагрузки стержн ми самосто тельно .With increasing pressure in the balloon, the base of the rack, due to a change in the inclination of the rods during the mutual sliding of the disks and rings, moves apart. After the required thrust pressure has been reached, the support is fixed in a certain position with the help of clamps located on the base discs. In this case, the structure provides the load sensing with the rods independently.
Предмет изобретени Subject invention
Стойка щахтной крепи, включающа пневматический баллон, соединенный с верхним и нижним основани ми, отличающа с тем, что, с целью увеличени жесткости крепи , основани снабжены дисками с фиксаторами угла поворота и шарнирно укрепленными стержн ми, которые расположены наклонно относительно оси стойки. ffus 1 Фиг 2A shoring support strut comprising a pneumatic balloon connected to the upper and lower bases, characterized in that, in order to increase the rigidity of the shank, the bases are equipped with discs with angle-lock holders and hinged rods that are inclined relative to the strut axis. ffus 1 FIG 2
