Processing tool for interior surface of laid piping

摘要

The processing tool includes a reed vehicle which can be driven into a reed piece (l) to be processed. The reed vehicle comprises a drive unit (2) and an endlessly revolving work head (3) with at least one associated cleaning (4.1) and/or coating tool (4.2) as well as a monitoring instrument (5). The work head is driven by the drive unit and the used tool is detachably attached to the work head. The monitoring instrument is pref. implemented by a water-cooled video camera with an illumination device. A processing beam, such as a pressurized sand beam or a flame of a torch, is pref. emitted by the tool, and hits the interior of the piping with an angle of less than 90 degrees.
