Изобретение относитс к горному депу и может быть испопьаовано при креплении очистных забоев в угольной и горнодобывающей промышленности.The invention relates to a mining depot and may be used when fixing stope faces in the coal and mining industries.

Известны перекрыти шахтной крепн, состо щие и Kocnvca, выдвижной части и съемной балки, выполненной с клином и вилкой 1. Балки перекрыти расположены непосредственно на насадке стойки, что в процессе передвижки крепи приводит к раскреплению кровли.Known overlapping of shaft fastenings, consisting of Kocnvca, sliding part and removable beams, made with a wedge and fork 1. The beams of the overlap are located directly on the nozzle rack, which in the process of shifting the lining leads to detachment of the roof.

Известны также перекрыти шахтной крепи, включающие гидравлическую стойку с верхним и нижним поршневым штоками и балки перекрыти 12 . Однако в период nep движки балок перекрыти происходит частичное раскрепление кровли, вызванное разгрузкой гидроопор, что приводит при слабых боковых породах к вывалам в кровле.Also known overlap shaft lining, including hydraulic rack with the upper and lower piston rods and beams overlap 12. However, in the period of the nep slider beam, there is a partial detachment of the roof, caused by the unloading of hydro-bearings, which, with weak lateral rocks, leads to dumps in the roof.

Целью изобретени вл етс расширение обпасги применени крепи.The aim of the invention is to expand the use of lining.

Это достигаетс тем, что верхний поршневой шток снабжен жестко закрепленным коромыслом с двум опорами, установленными с возможностью вертикального фиксирThis is achieved by the fact that the upper piston rod is equipped with a rigidly fixed rocker with two supports, which are installed with the possibility of vertical fixation.

ванного перемещени , при этом опоры могут быть св заны с коромыслом посредством шарнирного соединени .bathing movement, wherein the supports can be connected to the rocker by means of a hinge joint.

На фиг. 1 изображено предлагаемое перекрытие шахтной крепи; на фиг. 2 дан разрез А-А на фиг. 1; на фиг. 3 - разрез на фиг. 1; на фиг. 4 изображен элемент опоры перекрыти .FIG. 1 shows the proposed overlap of mine supports; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section in FIG. one; in fig. 4 shows the element of the support block.

Перекрытие шахтной крепи включает в себ гидравлическую стойку, содержащую нижний 1 и верхний 2 рабочие ципиндры, нижний 3 и верХЕшй 4 поришевые шгоки, загрузочные 5 и 6 и разгрузочные 7 и 8 клапаны, насадку 9, коромысло Юс цвум опорами 11 и 12, шарнир 13, соединенный с коробчатым элементом 14, фиксирующие .клинь 15, 16 и балки перекрыти 17 и 18The mine roofing overlap includes a hydraulic strut containing lower 1 and upper 2 working tsipindra, lower 3 and top 4 pischevye shgoki, loading 5 and 6 and unloading 7 and 8 valves, nozzle 9, Yus zvum beam with supports 11 and 12, hinge 13 connected to the box-like element 14, fixing the wedges 15, 16 and the beams of the overlap 17 and 18

Claims

The installation of the overlap is carried out as follows. When the working fluid is pumped into the lower working cylinder 1 through the loading valve 5, the lower piston rod 3 tears the column, which interacts with the roof of the nozzle 9. Before the working fluid j is injected. The upper working cylinder 2 has right and left supporting points 11 and 12 together with the bladders the overlaps 17 and 18 move in the grooves located at the ends of the rocker arm 1O, above the progress of the support epemings 1 and 12, which are then fixed with the pin 15 and W. After that, the working fluid through the charging valve 6 is fed to the upper working chi Pindr 2, in the rezupyagge of which the upper piston rod 4 tears rigidly fixed on it the yoke Y with the beams to block 17 and 18 into the roof. To move one of the ceiling beams (for example, beam 17), a wedge 15 is knocked out after the passage of the combine. In this case, the support 12 with the beam of the overlap 17 moves downwards to the course of the support 12 and move from the side to the bottom. After shifting, the support 12 moves up to the stop into the roof, and is fixed by the wedge 15. Similarly, the beam of the overlap 18 is moved. This overlap construction allows the roof to be fixed during the passage of the excavation machine without losing the bearing capacity of the lining. Claim 1. Overlap of mine support, including hydraulic rack with upper and lower piston rods and cross beams, characterized in that, in order to expand the field of application of the support, the upper piston rod is equipped with a fixed rocker with two supports installed with the possibility of vertical fixed movement . 2. The overlap of claim 1, characterized in that the supports are connected to the beam by means of a hinge joint. Sources of information taken into account in the examination; 1.
