Abstract: A flexible lance drive device has at least one drive motor in a first portion of a housing and a drive axle projecting across a second portion of the housing carrying a cylindrical spline drive roller. A plurality of cylindrical guide rollers on fixed axles span across the second portion of the housing aligned parallel to the spline drive roller. An endless belt wrapped around the at least one spline drive roller and guide rollers has a generally smooth outer surface and a transverse splined inner surface having splines shaped complementary to splines on the spline drive roller. A bias member supports a plurality of follower rollers each aligned vertically above one of the at least one spline drive roller and guide rollers operable to press each follower roller toward one of rollers to frictionally grip a flexible lance hose when sandwiched between the follower rollers and the endless belt.

Abstract: A system and an apparatus for positioning a plurality of flexible cleaning lances includes a frame removably fastened parallel to a row of tubes in a tube sheet within a domed end of a heat exchanger. A chassis support member is mounted on the frame for movement in an X direction. A chassis having spaced apart parallel box rail members is movably mounted on the chassis support member for movement of the chassis in a Y direction. A rotary arm extends from the chassis, and a flexible lance guide hand fastened to a distal end of the rotary arm is configured to maintain a plurality of flexible lance guide tubes in parallel alignment with the row of tubes irrespective of an angle between the rotary arm and the frame. The system may include a lance drive and a snout connected between the lance drive and the positioning apparatus.

Abstract: An apparatus for sensing an obstruction within a tube being cleaned and repetitively advancing and retracting a flexible high pressure fluid cleaning lance within the tube is disclosed. The apparatus monitors drive roller/belt position and actual hose position, compares the belt (expected travel) to hose position (travel) and generates a position difference, or mismatch. If the mismatch is above a predetermined level, the drive motor direction is reversed for a predetermined time interval, and forward operation restored after the predetermined time interval; and the sequence of repeating the reversing and restoring operations is continued until the position difference or mismatch no longer exceeds the predetermined difference threshold.

Abstract: A flexible lance drive device is disclosed that has, in a compact housing, a drive motor between an inner and an outer wall, a linear array of pairs of driven upper and lower drive rollers outside the outer wall coupled to the drive motor via shafts extending through both of the inner and outer walls. Each driven roller is fastened to its shaft via a quick release device. A drive sprocket is fastened to each shaft outside the inner wall. The drive motor is coupled to each of the drive sprockets via a serpentine belt carried outside the inner wall. The lower driven rollers are rotatably carried by the inner and outer walls. The upper driven rollers are rotatably carried by a block positioned between the inner and outer walls and coupled to the lower driven rollers by a pair of parallel links releasably biased by a piston driven linkage.

Abstract: A multiple flexible high pressure fluid cleaning lance drive apparatus includes at least a first drive motor having a first drive shaft, a spline drive roller mounted on the first drive shaft, a plurality of cylindrical guide rollers extending parallel to the spline drive roller, an endless belt wrapped around the spline drive roller and the plurality of guide rollers, and one or more follower roller modules each supporting a plurality of follower rollers for pressing against a single flexible lance. Each follower roller module independently presses its follower rollers toward the endless belt to grip the flexible lance sandwiched therebetween. Each module has an elongated block shaped housing having a central axis, a plurality of pneumatic cylinders and a piston rod carried in each pneumatic cylinder supporting a pair of spaced follower rollers that ride on the flexible lance captured between the endless belt and the follower rollers.
