Description
Предлагаетс механизированное иередиижное крепление, примен емое при выемке пологопадающих пластов угл .A mechanized and sequential fastener is proposed for use when excavating gently dipping coal seams.
Известное подобного типа крепление, состо щее из секций, имеет тот недостаток, что его секции взаимно св заны между собой, поэтому выдвижение каждой секции происходит только npi; упоре ее о соседнюю секцию.This type of known mount, consisting of sections, has the disadvantage that its sections are interconnected, so that each section only extends npi; focus it on the next section.
В предлагаемом креплении этот недостаток устранен тем, что перемещение секций происходит независимо друг от д.руга.In the proposed mount, this disadvantage is eliminated by the fact that the movement of sections occurs independently of each other.
На чертеже изображена секци креплени в плане и ее поперечный 1)азрез.The drawing shows the fastening section in the plan and its transverse 1) cut.
Секци состоит из следующих основных э.чементов; на)ужной рамы 1 П-образной форму, на которой установ.пены гидравлические вертикальные стойки 2, 3, 4, и внутренней рамы 5 с гидравлической вертикальной стойкой 6. П ты стоек 2 и 6, распо.юженние на разных рамках , св заны между собой горизонтальным домкратом 7.The section consists of the following main components; na) a u-shaped frame 1 is U-shaped, on which hydraulic vertical racks 2, 3, 4 are installed; and an internal frame 5 with a vertical hydraulic column 6. Five racks 2 and 6, located on different frames, are connected between a horizontal jack 7.
Передвижение секции ироизводитс по принципу шагани . При сн тии давлени жидкости в стойках 2, 3, 4 давление кровли воспринимает стойка 6, установленна на внутренней раме. По мере включе и в действие горизонтального домкрата 7, его шток 8 производит передвижку стоек 2, 3, 4 вместе с П-образпой рамой з сторону груди забо на длину хода штока. Перомеп1енные стойки распираютс между собой и кровлей и принимают на себ нагрузку, создаваемую кровлей. После этого стойка 6, освобожденна от нагрузки, подт гиваетс вмеcie с внутренней рамой в первоначальное положение по отношению к стойкам 2, 3, 4 и секци оказываетс вновь подготовленной к совершению при необходимости следующего цикла.The movement of the section is based on the pitch principle. When the fluid pressure is relieved in racks 2, 3, 4, the roof pressure is absorbed by the column 6 mounted on the inner frame. As the horizontal jack 7 is turned on and into operation, its rod 8 produces a movement of the pillars 2, 3, 4 together with the U-shaped frame on the side of the chest for the stroke length of the rod. The solid supports stand apart between themselves and the roof and take on the load created by the roof. After that, the rack 6, released from the load, is pushed together with the inner frame to its original position with respect to the racks 2, 3, 4 and the section is re-prepared for the next cycle if necessary.
