Abstract
A roll-out wheel has a base housing secured to a working surface. A rolling arm having a lever end and a working end pivots about a hinge point in the housing. A hand wheel and a pipe chuck are rotatably attached to the working end by a rolling sleeve. A pipe to be welded is securable on the pipe chuck and rotatable in unison with the hand wheel. Rotation of the hand wheel permits welding about the perimeter of the pipe without moving the welding tool. A clamping mechanism can permit or prevent rotation of the hand wheel. A pivoting mechanism can raise or lower the working end.
Claims20
A roll-out wheel for use in pipe welding, comprising:
- a base housing having means for removably securing the base housing to a surface;
- a rolling arm having a working end, a lever end, and a hinge point therebetween, wherein the rolling arm is pivotably attached to the base housing at the hinge point so as to be moveable in a vertical plane relative to the base housing;
- a means for locking the rolling arm so as to prevent pivoting of the rolling arm about the hinge point, wherein the means for locking comprises a locking port in the base housing and a locking pin configured for insertion into the locking port, wherein the locking pin contacts the lever end of the rolling arm when inserted into the locking port, thereby preventing pivoting of the rolling arm about the hinge point;
- a hand wheel attached to the working end of the rolling arm and oriented perpendicular to a longitudinal axis of the rolling arm, wherein the hand wheel is rotatable about the longitudinal axis of the rolling arm;
- and
- a pipe chuck affixed to a working side of the hand wheel opposite the rolling arm.
A roll-out wheel for use in pipe welding, comprising:
- a base housing having a plurality of base feet with bolt holes for removably securing the base housing to a surface;
- a rolling arm having a working end, a lever end, and a hinge point therebetween, wherein the rolling arm is pivotably attached to the base housing at the hinge point so as to be moveable in a vertical plane relative to the base housing;
- a rolling sleeve concentrically disposed about the working end of the rolling arm, wherein the rolling sleeve is rotatable about the longitudinal axis of the rolling arm;
- a hand wheel attached to the rolling sleeve on the working end of the rolling arm and oriented perpendicular to a longitudinal axis of the rolling arm, wherein the hand wheel is fixed to and rotatable with the rolling sleeve;
- a clamping mechanism having a support bar and a friction bar disposed adjacent to the rolling sleeve, wherein the friction bar pivots in relation to the support bar and is configured to be leveraged against the rolling sleeve to allow selective rotation of the hand wheel relative to the rolling arm, wherein the friction bar is leveraged by a threaded arm bolt advanced thereupon through the support arm;
- and
- a pipe chuck affixed to a working side of the hand wheel opposite the rolling arm.
