Description

В обоих случа х смену породоразрушающего инструмента производ т следующим образом .In both cases, the change of rock cutting tool is performed as follows.

От каждого луча 3 бара 2 отвод т стопорное устройство 9. Поворотом, например, посредством индивидуального гидравлического привода , конического колеса 7 и наход щихс  в зацеплении с НИ1М консольных конических шестерен 8 производ т синхронный поворот лучей 3 на требуемый угол, обеспечивающий выход в плоскость забо  необходимого нородоразрушающего инструмента 4. Затем фиксируют положение лучей 3 стопорным устройством 9.A locking device 9 is retracted from each beam 3 bars 2. By rotating, for example, by means of an individual hydraulic drive, the bevel wheel 7 and the cantilever bevel gears 8 which engage with the HIR1, synchronously rotate the beams 3 to the required angle the required destructive tool 4. Then fix the position of the beams 3 with a locking device 9.
