The device has supporting pedestals 10 and 11, drives 12 and 13 10 for moving shells and drives 14 and 15 for their expansion in the working. The drives 12 and 13 are essentially drives for extending the beams 5 relative to the shells. In the vertical guides 16 and 17, the movable ^{15 has} stops 18 connected with the drives 14 and 15. The shell 2 has a visor pivotally attached to it with a drive for turning it.

Работа устройства заключается в еле- , 20 дуюшем.The operation of the device is barely 20.

В сложном положении оболочки 1 и 2 сближены, консольные балки 5 входят в продольные зазоры 4, а упоры 18 втянуты вовнутрь оболочек. 25In a difficult position, the shells 1 and 2 are brought together, the cantilever beams 5 are included in the longitudinal gaps 4, and the stops 18 are pulled into the shells. 25

При необходимости перемещения устройства вперед и внедрения в отвал руды включают приводы 14, осуществляющие раскрепление устройства в выработке посредством упоров 18, перемещающихся в з₀вертикальных направляющих. При of ом передние упоры 18 остаются в исходном положении. Затем включают приводы 12 и 13 и передняя часть внутренней оболочки 1 скосами 9 внедряется в руду. При этом _3Jзазор между передней и задней частями оболочки 1 перекрывается наружной оболочкой 2. Далее включают приводы 15, которые раскрепляют переднюю часть оболочки 1 упорами 18 в выработке. Затем втягивают задние упоры 18 и при помощи домкратов приводов 12 и 13 осуществляют подтягивание задней части оболочки 1 к ее передней части. , При отходе от забоя шагание осуществляют аналогично. При этом козырек используют при из-, влечении устройства как предохранительное средство от вывалов руды.If you need to move the device forward and introduce into the dump ore include actuators 14, which carry out the fastening of the device in the excavation by means of stops 18 moving in h ₀ vertical guides. With of ohms, the front stops 18 remain in their original position. Then include drives 12 and 13 and the front of the inner shell 1 by bevels 9 is embedded in the ore. In this case, _{3J, the} gap between the front and rear parts of the shell 1 is blocked by the outer shell 2. Next, actuators 15 are included, which release the front of the shell 1 with stops 18 in the working. Then the rear stops 18 are retracted and, using the jacks of the drives 12 and 13, the rear part of the shell 1 is pulled to its front part. , When moving away from the face, pacing is carried out similarly. At the same time, the visor is used when the device is removed, as a safety measure against ore dumps.
