Abstract
Embodiments of the present invention relate to a pipeline wrench, that includes a housing which has a first end and a second end opposite the first end, a roller coupled with the housing near the first end of the housing, an idler pulley coupled with the housing, a belt between the roller and at least a portion of an opening, the belt extending beyond the first end of the housing, wherein a position of the idler pulley is adjustable such that a change in position results in a change in an amount of the belt that extends beyond the first end, and a first motor coupled with the axle of the roller, wherein operation of the first motor causes the axle to rotate.
Claims20
A pipeline wrench, comprising:
- a housing comprising a first end and a second end opposite the first end, wherein
- a portion of the first end is adjacent an opening configured to accept a section of pipe;
- a roller, comprising an axle, coupled with the housing near the first end of the housing;
- an idler pulley coupled with the housing;
- a belt between the roller and at least a portion of an opening, the belt extending beyond the first end of the housing, wherein a position of the idler pulley is adjustable such that a change in position results in a change in an amount of the belt that extends beyond the first end;
- and
- a first motor coupled with the axle of the roller, wherein operation of the first motor causes the roller to rotate.
A pipeline wrench, comprising:
- a housing having with a first end and a second end opposite the first end;
- the first end is forked to form an opening and comprises a right extension and a left extension;
- a first toothed-roller connected with the housing at the right extension of the first end of the housing;
- a second toothed-roller connected with the housing at the left extension of the first end of the housing;
- a track within the housing running lengthwise with the housing;
- an idler pulley wherein a portion of the idler pulley lies within the track;
- a first motor and piston connected to the idler pulley for positioning the idler pulley within the track;
- a toothed belt extending beyond the first end of the housing, located between each of the respective rollers and a portion of the opening and located between the idler pulley and the second end, wherein the teeth of the belt are configured to interlock with the teeth of the first and second rollers;
- a lifting arm connected to the housing;
- a respective second motor coupled to each axle of the first and second toothed-rollers;
- and
- a snubbing line connected to the second end of the housing.
A method of rotating a pipe section having a first end in contact with a second end of a stationary pipe section, the method comprising:
- positioning a first portion of a belt around an outside of the first pipe section, wherein a second portion of the belt is coupled with a wrench housing and the first portion extends beyond a first end of the wrench housing by an adjustable amount;
- locating the second portion of the belt to vary the adjustable amount such that the first pipe section contacts the first end of the housing and is frictionally engaged with the first portion of the belt;
- and
- moving the belt whereby the frictional engagement of the first portion of the belt and the first pipe section causes the first pipe section to rotate.
