  • Working tool of a machine for cleaning the outer surface of pipes
    Patent number: 4124914
    Abstract: Apparatus mountable on a pipeline of pipes welded end-to-end and having a self-propelled carriage mountable on the pipeline for travelling thereon. The carriage carries annular casings made to open up and receive the pipeline when mounting the carriage thereon and operble to a closed position circumferentially of the pipeline. A rotor travels in each casing circumferentially of the pipeline as the carriage moves axially of the pipeline. Each rotor has a tool holder that has a cleaning tool with a cutting edge tangential to the pipeline for cleaning. A cam surface on the tool holder moves in advance of the cutting edge and cams the tool holder upwardly when a weld is encountered between the pipe sections so that the cleaning tool is well protected.
