Abstract
The invention discloses a safe dismantling device of a smooth round drill pipe and a method thereof. The safe dismantling device comprises a connecting rod, an inner cylinder, a sliding sleeve, a clamping steel ball and a limit bolt. The connecting rod consists of the two parts of a central rod and a claw. One end of the inner cylinder is sleeved on the connecting rod in an inlaid mode and can slide axially on the connecting rod, the claw of the connecting rod is inserted into a notch of the inner cylinder, a round hole is formed at the other end of the inner cylinder, and the clamping steel ball is placed in the hole. The sliding sleeve is sleeved at the holed end of the inner cylinder and can slide axially at the holed end of the inner cylinder to extrude the clamping steel ball so that the clamping steel ball can clamp a square opening of the smooth round drill pipe. According to the safe dismantling device, based on the structural feature that the square opening is formed at the male thread end of the smooth round drill pipe, the clamping steel ball is adopted to clamp the square opening of the drill pipe, and the smooth round drill pipe is dismantled by means of the torque force of a hydraulic drilling rig. Therefore, not only is the dismantling efficiency of the smooth round drill pipe improved, but also hidden safety troubles in the dismantling process of the drill pipe are eliminated.
