Продольная направляющая имеет ползун 16, шарнирно соединенный с проушинами 17 выдвижной консоли 3.12. The supporting hydraulic stand 5 is pivotally mounted on a pull-out console 3 and rests on an arm I3 of a longitudinal guide 14 mounted along. means of support 15 on the frame (wooden) rack lining. The longitudinal guide has a slider 16, pivotally connected to the eyes 17 of the extendable console 3.

Гидрофицированный верхняк оборудуется съемными перекрытиями 18, выполненными из листовой стали.The hydrated upper is equipped with removable ceilings 18 made of sheet steel.

Крепление очистного забоя с применением гидрофицированных верхняков данной конструкции производится следуюцим образом.The fastening of the working face with the use of hydroficated tops of this design is carried out as follows.

После выемки угля в горизонтальной полосе на шаг установки крепи (1,01,5 м) гидрофицированшлй верхняк с помощью средств; подъема 19, установленных на выемочном комбайне 20, поднимается к потолочине забоя и посредством гидроДомкрата 6 распирается между деревянными стойками 21 и 22, ус тановленными у кровли и почвы пласта. При этом на верхний торец стойки 22 устанавливается опорой 15 продольная направляющая 14. Затем посредством опорной гидростойки 5 верхняк поджимается к потолочине и создаётся дополнительный распор деревянных стоек 21 и 22 за счет взаимодействия ползуна 16 с продольной напрявляющей 14. После установки и распо-~ ра верхняка продолжаются работы по вы-* емке угля в забое. По мере продвигания забоя комбайн гидростойки 4 распирается между деревянной стойкой 22 и производится анкерование деревянных стоек 22 к кровле пласта.After coal excavation in a horizontal strip at the step of installation of the lining (1.01.5 m), the hydrated hydrated top with the help of means; lift 19, mounted on a mining combine 20, rises to the bottom of the face and by means of a hydraulic jack 6 bursts between the wooden posts 21 and 22, installed at the roof and soil of the formation. At the same time, a longitudinal guide 14 is mounted on the upper end of the rack 22 with a support 15. Then, with the help of the hydraulic stand 5, the upper is pressed against the ceiling and an additional strut of the wooden posts 21 and 22 is created due to the interaction of the slider 16 with the longitudinal stress 14. After installation and placement of the upper * mining of coal in the face continues. As the face moves forward, the hydraulic stand 4 is bursting between the wooden stand 22 and the wooden posts 22 are anchored to the formation roof.

Claims

The invention relates to the mining industry and can be used in the development of MofljHbix steep seams by horizontal stripes in ascending order. Known hydroformed upper, for fastening the clearing faces of powerful steep seams, horizontal stripes in ascending order, including body and sliding element connected to it with a hydraulic jack. A disadvantage of the known construction is the lack of active backwater support and the lack of flexibility in the vertical plane. . . The closest to the invention to the technical essence and the achieved result is a hydrophilic upper c, comprising a casing, a retractable element mounted on opposite sides and a retractable console, a hydraulic jack that connects the retractable element to the casing, a hydroelectric construction hinged to the casing on the installation side of the sliding element, and the supporting hydroresistance associated with the housing f2 J. The disadvantage of this upper cc is the unreliability of ceiling fixing when used in a complex e with the wood bolting. The aim of the invention is to improve the reliability of fastening the ceiling of the bottom. The goal is achieved by the fact that the hydroficated top is provided with a slider, a ball {attached to the mounting console, and a longitudinal guide having a support in the upper part for mounting on the support and in the lower bracket - while the supporting hydrorack is pivotally attached to the bracket and retractable console. FIG. 1 shows a hydroficated upper side, side view; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. 1, in FIG. 4 - cross-section of the fixed clearing generation with equipment installed in it. The hydrated upper c consists of body 1 is installed} B 1x in it on opposite sides of the sliding element 2 and sliding console 3, an oblique hydraulic column 4 pivotally attached to the housing from the installation side of the sliding element supporting hydroresicle 5 and a hydraulic jack 6 connecting the mobile unit with the body . Sliding element 2 at the free end has a support shoe 7 pivotally connected to it. The sliding element is fixed relative to the body by means of a wedge lock 8. The sliding console 3 is fixed relative to the upper body by means of the fingers 9 installed in the lugs 10 of the body I and the holes 11 sliding console 3. The fastening of the hydraulic column 4 to the housing 1 is effected by means of the hinge 12. The supporting hydraulic column 5 is hingedly mounted on the sliding console 3 and rests on the bracket i 3 of the longitudinal guide 14, the mouth copulating on. means of support 15 on the frame (wooden Nyu) rack lining. The longitudinal direction has a slider 16 that is articulated with the eyes 17 of the sliding console 3. The hydrated upper is equipped with removable ceilings 18 made of sheet steel. The fastening of the clearing pond with the use of hydroficated tops of this construction is carried out in the following manner. After the coal has been dredged in a horizontal strip, the installation step of the support (1.01.5 m) has been activated (top with the help of means 3; lift 19 installed on the excavation combine 20, rises to the ceiling and spreads the strut between the bars) 21 and 22, installed near the roof and the soil of the reservoir, and on the upright end of the post 22, a longitudinal guide 15 is mounted by the support 15 14. Then, by means of the supporting hydraulic stand 5, it is pressed against the ceiling and an additional spreading of the uprights 21 and 22 is created due to the mutual The action of the slider 16 with the longitudinal guide 14. After installation and straightening of the top, work continues on coal mining in the face. As the bottom of the hydraulic column 4 moves forward, the wooden strut 22 spreads and the wooden struts 22 are anchored to the roof of the formation. Claims of the invention: Hydraulic upper, inclusive body, a sliding element mounted on opposite sides and a movable console, a hydraulic jack, connecting a sliding element to the body, a hydrostatic arm hinged to the frame Usu on the installation side of the sliding element, and a supporting hydrocounter associated with the hull, characterized in that, in order to increase the reliability of fixing the ceiling to the bottom, the Hydraulic upper is provided with a slider, hingedly attached to the movable console, and the longitudinal guide, which is pivotally attached to the support for mounting on the support bar, and in the bracket - the bracket, while the supporting hydrostatic. is armored attached to the croptine and sliding console. t1cT04tfflKH information taken into account during the examination 1.Patent of France No. 2302411, cl.
