Abstract (en)

1. Driving apparatus, especially for tube forward pressing operation, having a partial-cutting machine mounted suspended in a working tube, consisting of a cutter arm (16) which is mounted pivotably on a cutter arm carrier (14) on a joint (15) with joint axis extending transversely of the driving direction, which cutter arm carrier (14) in turn is mounted through a swivel fitting (13) with vertical axis of rotation (17) on a slide carriage (6) which is guided on a carriage guide arranged in the roof region of the working tube, characterized by the following features : the cutt arm (16) is in known manner formed at the same time as loading arm and provided with a circulating scraper chain (23) ; the cutter arm carrier (14) is mounted for pivoting on a swivel cross-fitting (13) about an axis (19) extending in the driving direction, which cross-fitting in turn is mounted on the carriage (6) laterally pivotably about the vertical axis (17).

Abstract (de)

Die erfindungsgemäße Vortriebseinrichtung weist einen Schneidarm (16) auf, der in bekannter Weise zugleich als Ladearm ausgebildet ist. Der Schneidarm ist an einem Schneidarmträger (14) angelenkt, der über einen Kreuzdrehstuhl (13) mit einem im Firstbereich des Arbeitsrohres (1) geführten Schlitten (6) verbunden ist. Der Schneidarm ist demgemäß um drei senkrecht zueinanderstehenden Raumachsen schwenkbar. Am Schlitten kann ein Ladeförderer (25) aufgehängt sein, der den Schlittenbewegungen folgt.
