Abstract
A pipe fitting tool configured to loosen a first section of pipe with respect to a second section of pipe. The pipe fitting tool includes a motor, a reciprocating member that reciprocates in response to activation of the motor, a holdback assembly configured to clamp and hold the second section of pipe, and a loosening mechanism configured to clamp and rotate the first section of pipe with respect to the second section of pipe in response to a first linear motion of the reciprocating member, and to release the first section of pipe in response to a second linear motion of the reciprocating member, the second linear motion being in a direction opposite the first linear motion.
Claims19
A pipe fitting tool configured to loosen a first section of pipe with respect to a second section of pipe, the pipe fitting tool comprising:
- a motor;
- a housing containing the motor;
- a battery removably coupled to the housing, the battery configured to provide power to the motor;
- a reciprocating member that reciprocates in response to activation of the motor;
- a holdback assembly including holdback assembly jaws that are actuatable to move the holdback assembly jaws toward and away from each other to clamp and hold the second section of pipe;
- and
- a loosening mechanism configured to
- clamp and rotate the first section of pipe with respect to the second section of pipe in response to a first linear motion of the reciprocating member, and
- release the first section of pipe in response to a second linear motion of the reciprocating member, the second linear motion being in a direction opposite the first linear motion.
A pipe fitting tool configured to loosen a first section of pipe with respect to a second section of pipe, the pipe fitting tool comprising:
- a motor;
- a lead screw configured to rotate in response to receiving torque from the motor;
- a carriage configured to move along the lead screw between a first position and a second position in response to rotation of the lead screw;
- a holdback assembly configured to clamp and hold the second section of pipe;
- and
- a jaw assembly configured to
- clamp and rotate the first section of pipe with respect to the second section of pipe in response to movement of the carriage from the first position to the second position, and
- release the first section of pipe in response to movement of the carriage from the second position to the first position.
A method of loosening a first section of pipe with respect to a second section of pipe, the method comprising:
- positioning first and second jaws of a holdback assembly on opposite sides of the second section of pipe;
- positioning third and fourth jaws of a drive assembly on opposite sides of the first section of pipe;
- rotating a handle of the holdback assembly in a tightening direction to move the first and second jaws toward each other to clamp the second section of pipe between the first and second jaws;
- and
- performing a loosening operation including
- activating a motor of the drive assembly in a loosening direction to cause the third and fourth jaws to clamp the first section of pipe between the third and fourth jaws;
- and
- continuing to operate the motor in the loosening direction to cause the third and fourth jaws to rotate the first section of pipe relative to the second section of pipe.
