Abstract

Rammbohrgerät mit einem in einem Gehäuse (1) axial beweg­ lichen, in seiner Bewegung durch ein mit einem Druckluft­ schlauch (6) verbundenes, in einem im Gehäuse (1) angeordne­ ten elastischen Zwischenstück (4) gelagertes Steuerrohr (3) gesteuerten Schlagkolben (2), bei dem das elastische Zwi­ schenstück (4) am Steuerrohr (3) und/oder im Gehäuse (1) angeordnet ist, wird die Montage des Zwischenstücks (4) vereinfacht. Außerdem treten weniger Beschädigungen am Ge­ häuse (1), Steuerrohr (3) und Druckluftschlauch (6) auf, und auch das Steuerrohr (3) läßt sich leichter montieren und demontieren. Ram drilling machine with an axially movable in a housing (1) lichen, in its movement by a compressed air hose (6) connected, arranged in one in the housing (1) th elastic intermediate piece (4) mounted head tube (3) controlled percussion piston (2), in which the elastic Zwi piece (4) on the head tube (3) and / or in the housing (1) is arranged, the assembly of the intermediate piece (4) simplified. In addition, there is less damage to the Ge housing (1), head tube (3) and compressed air hose (6), and the head tube (3) is easier to assemble and disassemble.
