A tube cleaning apparatus comprising a frame for attachment to a rotatable drive shaft, and a plurality of arms connected to the frame for movement between an extended position and a retracted position. The apparatus also comprises a plurality of cutter heads secured to the arms for engaging the inside surface of the tube, wherein the cutter heads are spaced from the inside surface of the tube when the arms are in the retracted position, and biasing means for urging the arms to the retracted position. Also disclosed is a method of operating the tube cleaning apparatus.
Claims3
A tube cleaning apparatus comprising:
- a frame for attachment to a rotatable drive shaft;
- a plurality of arms connected to the frame for movement between an extended position and a retracted position;
- a plurality of cutter heads secured to the arms for engaging the inside surface of the tube, wherein the cutter heads are spaced from the inside surface of the tube when the arms are in the retracted position;
- a contacting member supported by the frame for movement between an open position and a closed position, wherein movement of the contacting member from the open position to the closed position moves the arms toward the retracted position;
- and
- resilient means supported by the frame for urging the contacting member to the closed position.
In a tube cleaning apparatus of the type having a frame including a body and a shaft adapter for attachment to a rotatable drive shaft, a plurality of arms connected to the body for movement between an extended position and a retracted position, and a plurality of cutter heads secured to the arms for engaging the inside surface of a tube, wherein the cutter heads are spaced from the tube when the arms are in the retracted position, the improvement comprising:
- a contacting member supported by the frame for movement between an open position and a closed position, wherein movement of the contacting member from the open position to the closed position moves the arms toward the retracted position;
- and
- resilient means supported by the frame for urging the contacting member to the closed position.
