ABSTRACT:
In a device for guiding and tensioning supply lines for working tools movable along a straight guide, e.g. supply lines of a hydraulic hammer drill on an advance mounting, the advance of the working tool is implemented by means of a revolving transport chain driven by a sprocket wheel, and the supply line(s) are guided between the connections on the fixed guide and the connections on the working tool by a tension roller which causes a deflection about 180° and is movable in advance direction downstream the working tool conjointly therewith in the same direction but at half the advance speed, wherein the tension roller is slidably guided on the guide for the working tool transversely to its rotation axis, and wherein a pinion engages the transport chain for driving the movement of the tension roller and interacts with a fixed chain on the opposite side. To realize a controlled movement of the tension roller in both direction, a further transport wheel (14) for the advancement of the tension roller (8) is mounted onto the shaft (23) of the pinion (22) that engages the transport chain (4), for interaction with a fixed chain, a rack, a fixed traction rope, or the like.
