Abstract
The invention discloses a roller type non-creasing clamp holder for punching piers of an iron roughneck. The clamp holder is composed of a besides-star wheel, a roller pressing plate, a roller, a bolt, unbuckling rolling groove, a buckling rolling groove and the like. The outline of the bottom of the buckling rolling groove and the tangential direction of the buckling rotating direction form a buckling wedge angle, and the outline of the bottom of the unbuckling rolling groove and the tangential direction of the unbuckle rotating direction form an unbuckling wedge angle. According to the roller type non-creasing clamp holder, when the iron roughneck is used for buckling and unbuckling petroleum drilling columns, due to the fact that the roller is contacted with the outer wall of a petroleum drilling column joint, the prior condition that teeth of tooth-shaped piers bite the outer wall of the petroleum drilling column joint directly is avoided, and the damage on the petroleum drilling column joint is reduced. Meanwhile, due to the fact that the roller and the outer wall of the petroleum drilling column joint are locked automatically, the roller does not slip on the outer wall of the petroleum drilling column joint no matter how large is the torque in the unbuckling process. Therefore, the service life of the roller is prolonged, the auxiliary working time of changing the pier teeth is shortened, and working efficiency is improved.
