駆動装置。 The elevating member is supported so as to be movable up and down by the elevating guide member, the rotating member is supported so as to be horizontally pivotable by the elevating member, and the casing tightening member is attached to the rotating member so as to be openable and closable. In a casing tube tightening device for a boring machine in which a tightening jack for opening and closing the tightening member is provided on the casing tightening member, a slide ring is attached to the rotating member so as to be movable up and down, and a bearing is attached to the slide ring. A jack holder is mounted so as to be able to rotate in the horizontal direction, a driving hydraulic jack is interposed between the jack holder and the lifting member, and a tightening hydraulic jack is installed between the slide ring and the rotating member. A jack is installed, and the head side pressure chamber and rod side pressure chamber of the tightening hydraulic jack are connected to the head side pressure chamber and rod side pressure chamber of the opening/closing tightening jack, respectively, by a hydraulic circuit. Features: Opening/closing drive device for casing tube tightening device for boring machines.
