Description

Изобретение OTEIOCHTCH к горно-добывающей промышленности, а именно к креплению очистных забоев механизированными креп ми.The invention of the OTEIOCHTCH to the mining industry, namely, to the attachment of mining faces with mechanized roof supports.

Целью, изобретени вл етс повышение эффективности управлени наклоном основани на слабой почве.The purpose of the invention is to increase the effectiveness of the control of the slope of the base on weak soil.

На фиг,1 показано устройство дл передвижки основани при выдвинутой cBKutm крепи, вид сбоку,- на фиг. 2 - то же, при выдвинутом конвейере; на фиг,3 - разрез А-А на фиг,1; на фиг,4 - разрез Б-Б на фиг,2.FIG. 1 shows a device for moving the base with the cBKutm extended, side view, FIG. 2 - the same, with extended conveyor; FIG. 3 is a section A-A in FIG. 1; FIG. 4 is a section BB in FIG. 2.

Устройство дл передвижки основани секции механизгфованной крепи содержит продольные полозы 1, упор 2 с продольным пазом 3, направл ющую балку 4, снабженную клиновой опорой 5 и соединенную шарниром 6 с конвейером 7, а цапфами 8 - с домкратом 9 передвижени , В поперечной траверсе на оси 10 установлен двуплечий рычаг 11, Один его конец осью 12 соединен с т гой 13, котора с помощью оси 14 установлена в продольном пазу 3 упора 2 и соединена с домкратом 9 передвижени , В упоре 2 выполнен выступ 15,The device for shifting the base of the mechanized support section contains longitudinal runners 1, an emphasis 2 with a longitudinal groove 3, a guide beam 4 equipped with a wedge support 5 and connected by a hinge 6 with a conveyor 7, and the trunnions 8 with a movement jack 9, In the transverse crosshead on the axis 10 a double-shouldered lever 11 is installed. One end of it is connected by an axis 12 to a pull 13, which by means of an axis 14 is installed in a longitudinal groove 3 of the anvil 2 and connected to the movement jack 9, the projection 15 has a protrusion 15,

Устройство работает следующим образом .The device works as follows.

Перед выдвижкой секции крепи жидкость подаетс в пординевую полость домкрата 9 передвижени . Домкрат раздвигаетс и ось 14 вместе с вторым концом т ги 13 перемещаетс в пазу 3 упора 2 к забою. При этом т га 13 своим верхним концом поворачивает на оси 10 двуплечий рычаг до контакта с выступом 15,Before advancing the support section, liquid is supplied to the pordine cavity of the movement jack 9. The jack is moved apart and the axis 14 together with the second end of the rod 13 moves in the groove 3 of the stop 2 to the face. At the same time, the ha 13, with its upper end, rotates on the axis 10 two-armed arms until it comes into contact with the protrusion 15,

вейера жидкость подаетс в штоковую полость домкрата 9 передвижени . Дом крат сокращаетс , и ось 14 вместе с вторым концом т ги 13 перемещаетс продольном пазу 3 к завалу. При это т га 13 поворачивает двуплечий рыча 11, которьй выходит из контакта с клиновой опорой 5 направл ющей балки 4, За счет этого обеспечиваетс свободна выдвижка конвейера 7 (фиг,2),the fan is fed into the rod cavity of the movement jack 9. The house is shortened, and the axis 14 together with the second end of the rod 13 moves to the longitudinal groove 3 to the dam. At this t ha 13 rotates a double-armed lever 11, which comes out of contact with the wedge support 5 of the guide beam 4. This ensures that the extension of the conveyor 7 is free (Fig. 2),
