发明名称 CABLE GUIDE FOR DRILL LINE SLIP AND CUT OPERATIONS ON A DRILLING RIG AND RELATED METHOD FOR ACHIEVING A TENSIONED STATE OF THE DRILL LINE
摘要 A cable guide for supporting a slack portion of a drill line during a slip and cut operation features a top body portion and a bottom body portion held together in spaced relation to one another such that inner ends of the top and bottom body portions are facing but spaced from one another. At least one contact surface is carried on each body portion, and a pair of the contact surfaces are aligned in a working position so as to collectively define a pathway between the inner ends of the top and bottom body portions along which the slack portion of the drill line is to be routed. The cable guide also features an adjustable couplmg mechanism arranged for displacing the inner ends of the top and bottom body portions towards and away from one another so as to adjust a size of the pathway.
