(54) СЕКЦИЯ -ШАХТНОЙ МЕХАНИЗИРОВАННОЙ КРЕПИ(54) SECTION - SHAFT MECHANIZED FIXTURE

II

Изобретение относитс к горному делу, в частности к креп м очистных забоев крутопадающих угольных пластов при щитовой системе разработки.The invention relates to mining, in particular to the fortifications of cleaning faces of steeply dipping coal seams under a shield system of development.

Известна секци шахтной механизированной крепи, включающа основание, перекрытие, гидростойку, составную оградительную часть крепи, св занную с перекрытием посредстве распорных 10 звеньев, одно из которых установлено шарнирно, и средство, дл раздвижки огра.дительной части 6 виде гидроцилиндра , второе распорное звено установлено также шарнирно, а огради- J5 тельна часть выполнена из трех составных частей J верхн и нижн из которых выполнены в виде наклонных в сторону завсша жестких плит, которые соединены между собой посредствс м20 гидроцилиндра раздвижки оградительной части и с перекрытием и основанием посредством ограничивающих опорных . св зей, при этом их свободные торцовые плоскости установлены с возмож- 25 ностью взаимодействи с основанием и перекрытием 1.The known section of mine mechanized lining, including the base, the overlap, the hydraulic post, the integral protective part of the lining, connected with the overlap by means of spacer 10 links, one of which is hinged, and a means for extending the restriction portion 6 of the hydraulic cylinder it is also articulated, and the protective part, J5, is made of three components J, the upper and lower parts of which are made in the form of rigid plates inclined towards the end, which are interconnected by means of m20 g drotsilindra razdvizhki fencing part and overlapping and the base by limiting reference. connections, while their free end planes are installed with the possibility of interaction with the base and the overlap 1.

Недостатком этой крепи вл етс небольшой шаг передвижени , который ограничиваетс опорными св з ми. 30The disadvantage of this support is a small step of movement, which is limited by supporting links. thirty

Целью изобретени вл етс увеличение шага передвижени крепи.The aim of the invention is to increase the step of movement of the support.

Поставленна цель достигаетс тем, что шарниры ограничивающих опорных св зей установлены с возможностью перемещени на основании и перекрытии секции в направлении ее перемещени посредством направл ющих, которые выполнены с фиксирующими упорами.The goal is achieved by the fact that the hinges of the limiting supporting links are mounted with the possibility of movement on the base and the overlapping of the section in the direction of its movement by means of guides which are made with locking lugs.

На фиг. 1 изображен общий вид крепина фиг. 2 - местный разрез подвиж- ного шарнира (узел на фиг. 1);на фиг. 3 - разрез А-А на фиг. 2.FIG. 1 shows a general view of the crepe crepe of FIG. 2 is a local section of the movable hinge (node in FIG. 1); FIG. 3 shows section A-A in FIG. 2

Claims

The lining section consists of the base 1, the overlap 2 located on the hydraulic post 3. The supporting seats of the hydraulic post on the overlap 1 and the base 2 are pivotally connected by means of the movable distance members 4 with the supports of the hydraulic jack 5 mounted on the brackets of the middle part of the composite fence b. The middle part of the composite fencing 6 is made in the form of telescopic plates moving relative to each other, depending on the degree of sliding of the hygrodrac 5. The upper and lower parts 7 of the hinge-knot are made in the form of rigid plates connected movably with the middle part on the hinges, whose planes are inclined to the side the dam, and their free face planes are installed with the possibility of interaction with the base 1 and the overlapping 2 and are connected to them pivotally by means of limiting support links 8. Hinges 9 on the bases 1 overlap x 2 are movable along the axis of the section in the direction of the guide dam 10 having locating lugs 11 the starting position of the hinge 9, with the thrust and the shifting support frame. If necessary, the hinges 9 can be installed in a predetermined position when adjusting the lamination according to the thickness of the reservoir and the step of moving to the chest, especially after the extraction body. The support movement is carried out in a known manner by pushing the barrier part 6 away from the dam rocks as a result of a change in the tilt angles of the distance members 4 and the movable parts of the fence 7, as well as limiting support links 8, the hinges 9 of which, on the base 1 and the ceiling 2, are mobile and the need to select a full stroke is moved along the rails. Thus, the movable hinges 9 exclude the restriction of the movement of the protective part with the full spreading of the hydraulic jack and the extreme positions of the distance links, which provides an increase in the step of movement of the support, and is also important in the operation of the support in a rapidly changing power of the coal seam being developed. Claims Section of mine mechanized lining according to ed. St. 599088, characterized in that, in order to increase the movement of the support, the hinges of the limiting supporting links are installed with the possibility of moving on the base and the overlapping of the section in the direction of its movement by means of guides which are made with locking lugs.
