Abstract
A tool for lifting, rotating, and/or manipulating tubulars comprises an inserting head positioned at the end of a shaft acting as a handle. The insertion head comprises a conical shape defined by smaller-diameter end cap, a larger-diameter rear cap, and frame bars connecting the two. On the frame bars are mounted rails along the angle of the conical shape, and slips having a negative angle corresponding to the conical angle of the rails. In use, the head is inserted into a tubular, which abuts a flared portion of the slips and pushes them back along the rails, until the slips make contact with the inner diameter of the tubular, enabling it to be pushed around and lifted.
Claims8
A tool for manipulating a tubular comprising:
- an insertion head comprising an end cap, a rear cap, and a plurality of frames connecting the end cap and the rear cap, the end cap comprising a first diameter, and the rear cap comprising a second diameter larger than the first diameter;
- a plurality of rails, respectively mounted onto the plurality of frames;
- a plurality of slips, respectively mounted onto the respective plurality of rails, the plurality of slips having freedom of motion along the plurality rails between the end cap and the rear cap;
- and
- a shaft extending to the rear cap,
- wherein the plurality of slips are pushed back and out along the plurality of rails when the insertion head is inserted into the tubular, such that the plurality of slips contact an inner diameter of the tubular.
