Abstract
An improved cleaning system for a horizontal type tube assembly which can achieve cleaning of the outer surfaces of the tubes in the tube assembly automatically by remote control without necessitating human labor of workers who are compelled to work in a narrow limited space, is disclosed. The improvements reside in that the cleaning system comprises a cleaning main body section including a cleaning jig for an outer surface of a tube, a screw and a motor in combination for reciprocating the cleaning jig in the axial direction of the tube, another motor for diverting the direction of the cleaning jig, and a support plate for supporting the aforementioned members; an upper traversing section including a winding drum, lifting wires and a winding motor in combination for raising and lowering the cleaning main body section to any arbitrary height, a traveling roller for moving in the axial direction of the tube, and a drive motor for driving the traveling roller; the cleaning main body section further including a sensor for detecting the tube during rising and lowering of the cleaning main body section, and an urging plate which is mounted to the cleaning main body section via an expans…
