DEVICE FOR REMOVING ROTATING HEAD RUBBERS FROM DRILL PIPE

摘要

A device for removing rotating head rubbers from drill pipe comprising a base member, vertical shaft, lower pipe attachment bracket, left arm, right arm, diagonal shaft and upper pipe attachment member. Proximal ends of the left and right arms are welded to a top end of the vertical shaft, and the left and right arms lie in the same horizontal plane. Proximal ends of the left and right arms are welded together and distal ends of the left and right arms are separated so that the arms form a V-shaped fork. The diagonal shaft is welded to the top end of the vertical shaft at an upward angle of approximately 45 degrees. The upper pipe attachment member is removably inserted into a distal end of the diagonal shaft.

1. A device for removing rotating head rubbers from drill pipe, the device comprising:
(a) a base member; (b) a vertical shaft; (c) a lower pipe attachment bracket; (d) a left arm; (e) a right arm; (f) a diagonal shaft; and (j) an upper pipe attachment member; wherein the base member is removably inserted into a lower end of the vertical shaft; wherein the lower pipe attachment bracket is welded to the vertical shaft in a central portion of the vertical shaft; wherein each of the left arm and the right arm has a proximal end, and the proximal ends of the left arm and the right arm are welded to a top end of the vertical shaft; wherein the left arm and the right arm each lies in a horizontal plane, and the horizontal plane in which the left arm lies is the same as the horizontal plane in which the right arm lies; wherein the proximal ends of the left arm and the right arm are welded together and the distal ends of the left arm and the right arm separated so that the left arm and the right arm form a V-shaped fork; wherein the diagonal shaft is welded to the top end of the vertical shaft at an upward angle of approximately 45 degrees from the horizontal plane in which the left arm and the right arm lie; wherein the diagonal shaft has a distal end, and the distal end faces in an opposite direction from an open end of the V-shaped fork formed by the left arm and the right arm; and wherein the upper pipe attachment member is removably inserted into a distal end of the diagonal shaft.
