US Patent 7530363 High pressure tube cleaning apparatus

An assembly for rotating and axially directing a high pressure spray hose and spray head to clean residue from tubing bores. Modular, remotely controlled subassemblies are concentrically aligned and mounted to a hose drive framework to rotate in synchrony and direct a high-pressure water hose and spray head. A hose drive assembly controls hose rotation and axial hose movement via biased pinch wheels. A resilient, eccentric linkage controls pinch wheel pressure. A layering arm uniformly layers the hose at a hose reel. Rotational sensors and/or a pneumatic booster and a disk brake assembly facilitate non-kinking hose collection and release without spillage. A re-configurable hose support framework contains a driven walking beam having drive assemblies that laterally and vertically index a hose support and control the inclination of the walking beam.
