Abstract

Bei einem Rammbohrgerät (1) mit in einem rohrförmigen Ge­ häuse (2) verschiebbaren Schlagkolben (3), einem verschieb­ bar gelagerten, durch eine Gehäusespitze (6) hindurchgeführ­ ten Meißel (10), der mit einem Bund (14) in einer einen vorderen und einen hinteren, den Hubweg (19) des Meißels (10) begrenzenden Anschlag (20, 15) aufweisenden Gehäu­ sebohrung (13) geführt, und mit einem in den Arbeitsraum (17) des Schlagkolbens (3) hineinragenden Zapfen (16) ver­ sehen ist, werden Prellschläge vermieden, wenn die Vor­ kraglänge (18) des Zapfens (16) kleiner als der maximale Hubweg (19) des Bundes (14) zwischen den Anschlägen (15, 20) ist. In a ram boring machine (1) with in a tubular Ge housing (2) sliding percussion piston (3), one sliding bar mounted, passed through a housing tip (6) ten chisel (10) with a collar (14) in one front and a rear, the stroke (19) of the chisel (10) limiting stop (20, 15) housing bore (13), and with one in the work area (17) of the percussion piston (3) protruding pin (16) ver can be seen bouncing is avoided if the front cantilever length (18) of the pin (16) is less than the maximum Stroke (19) of the federal government (14) between the stops (15, 20) is.
