Изобретение относитс к механизированному креплению очистных выработок при разработке пластовых месторождений.The invention relates to the mechanized fastening of clearing workings in the development of stratum deposits.
Известны гидросистемы секции шахтных крепей, включающие гидростойку, предохранительпый клапан, сервоклапаи, гидрораспределитель , трубопроводы и гидроаккумул тор.The hydraulic systems of the shaft support section are known, including a hydraulic post, a safety valve, a servo valve, a hydraulic valve, pipelines and a hydraulic accumulator.
Дл повы.шени надежности поддержани кровли в предлагаемой гидросистеме секции шахтной крепи сервоклапан выполнен в виде обратного разгрузочного элемента. - На чертеже приведена принципиальна схема секции шахтной крепи. ; Гидросистема секции оюдключсна к на порион 1 и сливной 2 магистрал м с помощью гидрораспределител 3 и трубопроводов 4, 5, 6 и 7. Гидросистема секции включает гидростойку 8 с гидрозамком 9 и предохранительным клапаном 10, -выход последнего соединен с рабочей полостью Гидроаккумул тора И, входом, второго -прсдохраиительного клапана 12 и Клапанной полостью 13 обратного разгрузочного элемента 14, подклапонна полость 1Г) которого соединена трубопроводом 4 с распр еделителем 3, штоковоп полостью гилростойк S и полостью толкател гидролпмк-з 9. Полость Ifj толкател элемента 14 L-oc:iiiiiciia трубопроводом 5 с распределителем . и подклаплинои поло.стыо шдроза.мкм 9.In order to increase the reliability of roof maintenance in the proposed hydraulic system of the shaft support section, the servo valve is designed as a return discharge element. - The drawing shows a schematic diagram of the shaft support section. ; The hydraulic system of the section is connected to the porion 1 and the drain 2 line using hydraulic distributor 3 and pipelines 4, 5, 6 and 7. The hydraulic system of the section includes a hydraulic post 8 with a hydraulic lock 9 and a safety valve 10, the outlet of the latter is connected to the working cavity of the hydraulic accumulator I, the inlet of the second one — the pressure suppressor valve 12 and the valve cavity 13 of the return discharge element 14, the sub valve cavity 1G) of which is connected by pipeline 4 to the distributor 3, the rod of the hygroscal cavity C and the hydraulic valve pusher 9. Bands Ifj pusher element 14 L-oc: iiiiiciia pipeline 5 with valve. and subclinical polo.stoto shdroza.mkm 9.
При распоре секции крепи рабочую жидкость от гидрораспределител 3 по трубопроводу 5 подают в полость 16 элемента 14 и через гидрозамок в поршневую полость гидростойки 8. При этом гидростойка 8 распираетс и разгружаетс гидроаккуммул тор 11. По мере просадки гидростойки 8 жидкость накапливаетс в рабочейПОЛОСТИ гидроаккумул тора 1, при этом повышаетс давление в его полости и создаетс противодавление на выходе предохранительного клапана 10. Следующа просадка гидростойки шроизойдет При давлении, равном сумме давлений настройки клапана 10 и давлени в рабочей полости гидроаккумул тора 11. Плавное нарастание сопротивлени гидростойки 8 будет продолжатьс до тех пор, пока давление в полости тидроаккуМул тора-П не достигнет давлени срабатывани второго предохранитольного клапана 12. При этом гидростойка выйдет на режим посто нного сопротивлени , определ емого суммой давлений срабатывани предохранительных клапанов 10 и 12.When the lining section is supported, the working fluid from the hydraulic distributor 3 is fed through the pipeline 5 into the cavity 16 of the element 14 and through the hydraulic lock into the piston cavity of the hydroresistance 8. In this case, the hydrostatic accumulator 8 discharges and discharges the hydroaccumulator 11. As the hydroresistance 8 subsides, the liquid accumulates in the working hydraulic capacity of the hydroaccumulator 11 at the same time, the pressure in the cavity rises and a back pressure is created at the outlet of the safety valve 10. The following drawdown of the hydraulic rack is observed. At a pressure equal to the sum of the valve setting pressures 10 and the pressure in the working cavity of the hydroaccumulator 11. A smooth increase in the resistance of the hydroresistant 8 will continue until the pressure in the cavity of the Motor-P thydroaccess reaches the operating pressure of the second safety valve 12. In this case, the hydroresistance will reach the constant resistance mode determined by the sum of the actuation pressures of the safety valves 10 and 12.

| SU419618A1 (en) | DEVICE FOR DIVERSIFIED DEPARTMENT OF THE FIRST HOLTING LIFE The device is characterized in that it is equipped with two elastic walls, which form a sealed ring with the cuffs and corus. evye camera. This allows to increase the reliability of the device in operation, to ensure the accuracy of delivery of the mixture to the local area and uniform mixing of the components. In the drawing, the described device is shown in section. Oio contains hydraulic iaxer 90 manners <, /, contact extraction valves 2, elastic shells 3, a working annular chamber 4, a housing o, claian 6, a support frame 7 with a support mechanism 8, a fixing Topiibii'i screw 9, a branch pipe 10 and a piston 11. The device is released into the casing by pumping - compressor column. The pressure from the cavity of the pumping-compressor column is transmitted to the inner shells of elastic containers during direct pumping of the fluid through the spring / column. For ycTpoiicTBa, its olor-mechanism-pump-com-actuation of interactions of fix-frames (for example, spring hooks! 11), installed in the packer or in the task; 1st place of the casing string is necessary. When the Ustronism meter, the impregnator, and the packer, previously installed on the casing string, is reached, the mechanism 8 is supported by the packer fasteners. and the supporting non-opener 7 rises up to the stop and closes the channel through which the nest is!) The pastoral-compressor column connects with the intertubular space. The pressure in the iiacociio-compressor column increases, that s.'1zhuyrg signal about the exact installation of the device. The splinter // rises under the action of laplens from the bottom, transmitted through the cavity and the lateral opening of the nozzle 10. Raising the piston ensures that the support and reamers are maintained in the working position in case of premature cutting of the packer clips device). The increase in pressure and leads to the operation of the chapass 6. As a result, the working pressure is transmitted to the working chamber 4. | |
