<p>The invention relates to a device for operation in pipelines (2), especially sludge exhaustion of sewers, said device comprising a remote-controlled, self-acting caterpillar vehicle (1). The drive (7) and tension wheels (10) supporting the drive belt (9) of the caterpillar vehicle (1) are vertically adjustable relative to the caterpillar vehicle (1) and pivotably arranged in a vertical plane perpendicular to the direction of travel of the caterpillar vehicle (1). The caterpillar vehicle (1) comprises an upper member (3) provided on its underside with a means (11) for fastening a tool in the form of for example a suction line (12). Means (5) are arranged for stepless adjustment of the distance between the upper member (3) and frame members (4) supporting the drive (7) and tension wheels (10). Furthermore, the caterpillar vehicle (1) comprises means (6) for control and absorption of the relative motion between the upper member (3) and the frame members (4). The frame members (4) comprise motors (8) for driving the drive wheels (7) and swinging the drive wheels (7) and the tension wheels (10). The means of adjustment (5) are for example hydraulically operated. The caterpillar vehicle (1) is adaptable to work in pipelines of varying dimensions simultaneously as the location of the fastening means (11) enables that the position of the tool (12) relative to the pipeline (2) can be adjusted steplessly.</p> |
