ABSTRACT:
An assembly for rotating and axially directing a high pressure spray hose and spray head to clean residue from the bores of thermal transfer tubes. Modular subassemblies are concentrically aligned and mounted to rotate in synchrony and direct a high-pressure water hose and spray head. An air controlled operator control gun directs spray pressure and hose movement. A hose drive assembly controls hose rotation and axial hose movement via biased pinch wheels that abut the hose. An eccentric linkage and spring tensioners coupled to the pinch wheels release and re-engage the wheels to the hose at a preset pressure. A layering arm stacks the hose in uniform layers at a hose reel. Rotational sensors and/or a pneumatic booster and a disk brake assembly facilitate hose collection and release without kinking or spillage.
