Description

На фиг. 1 изображено устройство ДЛЯ управлени  выемочным агрегатом, поперечное сечение; на фиг. 2 вид А на фиг. 1. Устройство дл  управлени  выемоч ным агрегатом по гипсометрии пласта включает подвижные в вертикальной плоскости сгекции 1 и 2 направл ницей с забойной и завально сторон. Кажда  секци  направл квдей шарнирно со единена с двухштоковым гидроцилиндром: забойным 3 .и завальньм 4, кот рые жестко укреплены на прбтивбположных бортах конвейерного, става. Рабочие полости; подноршнева  5 и надпоршнёва  6 забойного гидроцилиндра 3 сй заны последойательно с завальньвд гидроцилиндром 4, имеющим со ответствующие полости, и с линией управлени  через односторонние сдво енные гидрозамки 7 и 8, управл емые через гидррлинию 9, ,и трехпозидионный гидрораспределитель 10. Гидроцилиндры 11 расположены в полости за-войной 12 и завальной 13 опор выемоч ной машины 14, опоры 12 и 13 имеют. Т-образную сферическую опорную повер . ность. Гидроцилиндры 11 шарнирно, соединены q одной стороны с выемочной машиной 14, а с другой - с лыжами 15, расположенными с забойной стО роны. Лыжи 15 и 16 имеют Т-образные Поперечные .. Кажда  секци  1 и 2 направл ющей снабжены соединитель ным звеном 17. Устройство работает следующим об . разом. FIG. 1 shows a device for controlling an excavation unit, a cross section; in fig. 2 view A in FIG. 1. A device for controlling the extraction unit on the hypsometry of the formation includes 1 and 2 moving in the vertical plane of the section from the bottomhole side and the bulkhead side. Each section is hingedly connected to a two-rod hydraulic cylinder: downhole 3. And filled 4, which are rigidly fixed on the flange of the conveyor belt. Working cavity; Podnorshneva 5 and Nadporshneva 6 of the bottomhole hydraulic cylinder 3 are successively connected with the hydraulic cylinder 4, having corresponding cavities, and with the control line through unidirectional dual hydraulic locks 7 and 8, which are controlled through the hydraulic line 9, and the three-dimensional hydraulic lock 7 and 8, and the three-point hydrodynamic locks 7 and 8, which are controlled by means of the hydraulic line 9, and the three-dimensional hydraulic lock 7 and 8, and the three-site hydraulic lock 7 and 8, which are controlled by means of the hydraulic line 9, and the three-dimensional hydraulic lock 7 and 8, which are controlled by means of the hydraulic line 9, and the three-dimensional hydraulic lock 7 and 8, and the three-point hydraulic lock 7 and 8, which are controlled by means of the hydraulic line 9, and the three-point hydraulic lock 7 and 8, and the three-point hydraulic lock 7 and 8, which are controlled by means of the hydraulic line 9, and the three-dimensional hydraulic lock 7 and 8, which are controlled by the hydraulic line 9, and the three-dimensional hydraulic lock 7 and 8, and the three-dimensional hydraulic lock 7 and 8, which are controlled by the hydraulic line 9, and the three-dimensional hydraulic lock 7 and 8, and three-site hydraulic, 7 cavities 12 behind the warhead and 13 of the crushing 13 supports of the excavation machine 14, supports 12 and 13 have. T-shaped spherical support turn. ness The hydraulic cylinders 11 are articulated, q are connected on one side to the excavation machine 14, and on the other to skis 15 located on the bottom side. Skis 15 and 16 have a T-shaped Transverse. Each section 1 and 2 of the track is provided with a connecting link 17. The device operates as follows. at once.

При.включении гидрораспределител  10 в одно из крайних положений односторонние сдвоенные .гидрозамки 7 и 8 открываютс  управл ющим импульсом через гидролинию 9 управлени . Рабоча  жидкость под давлением поступает в подпоршневую полость 5 или надпоршневую 6 забойного гидроцилиндра 3, смеща  секцию 1 направл ющей, а следовательно через лыжу 15 и забойную опору 12 выемочной машины 14 вверх или -вниз от нейтрального положени ., Одновременно происходит перемещение завального гидроцилиндра 4,имеющего соответств,ующие полости, что игидроцилиндр 3, соединенного последовательно с забойным гидроцилиндром , 3 через односторонние сдвоенные ,ги-, дроэамки 7 и 8 и гидрораспределитель 10, вверх:или вниз от нейтрального положени  соответственно перемещению поршн  забойного гидроцилиндра 3. Через,секцию 2 направл ющей, лыжу 16 и опору 13. Такое вертикальноеПеремещение передаетс  выемочной машине 14. Благодар определен: ному соотношению рабочих площадей поршней соотношение величин рабочих ходов гидроцилиндров вертикальногоWhen the control valve 10 is turned on at one of the extreme positions, one-way dual lock locks 7 and 8 are opened with a control pulse through control line 9. The working fluid under pressure enters the piston cavity 5 or above piston 6 downhole hydraulic cylinder 3, displacing section 1 of the guide, and therefore through ski 15 and downhole bearing 12 of the excavation machine 14 up or down from the neutral position. At the same time, the downhole hydraulic cylinder 4 moves, having corresponding cavities that the hydraulic cylinder 3, connected in series with the downhole hydraulic cylinder, 3 through one-sided double, gidroami 7 and 8 and the valve 10, up: or down from the neutral position and according to the movement of the piston of the downhole hydraulic cylinder 3. Through the section 2 of the guide, the ski 16 and the support 13. Such vertical movement is transferred to the excavation machine 14. The thanks is determined by: the ratio of the working areas of the pistons to the vertical displacement of the hydraulic cylinders
