The device comprises a hydraulic base, a hydraulic cylinder, a clamping ring and fixing devices, wherein the clamping ring comprises two semicircular snap rings which are arranged symmetrically; the snap rings are provided with open ends and enclosed ends; the enclosed ends of the two symmetrical snap rings are connected through a hinge; connecting plates are arranged at the open ends of the two snap rings; the connecting plates are provided with threaded through holes which are matched with a screw rod and a screw cap; the inner walls of the snap rings are provided with threaded surfaces; a plurality of fixing blocks are uniformly arranged on the outer walls of the snap rings. According to the device, the clamping ring is set into two symmetrical semicircular snap rings, the enclosed ends of the two snap rings are connected through the hinge, and the open ends of the two snap rings are connected by matching the screw rod with a screw, so that the open ends of the snap rings can be opened and closed freely, a drill rod can be inserted conveniently, and the problem of difficulty in operating during insertion of the drill rod into a clamping portion of the conventional detaching device is solved.
Description
Technical field
The present invention relates to provision for disengagement field, particularly, relates to a kind of device dismantling multisection type oil drill rocker.
Background technology
in the recovery process of oil, drilling rod is a kind of requisite instrument, because oil well is general all darker, so the drilling rod of recover petroleum generally uses the drilling rod of multisection type, the joint drilling rod damaged is changed when a certain section of drill pipe wear, when splitting the drilling rod damaged, then needs split the drilling rod damaged with provision for disengagement after first being fixed by the two ends drilling rod damaging drilling rod.Existing provision for disengagement all adopts the cylinder clamping drilling rod of hollow usually, and fluid pressure type drive unit drives drilling rod to rotate in the axial direction, thus drilling rod is split.Existing provision for disengagement needs the cylinder clamping section of drilling rod being inserted hollow when clamping drilling rod, and drilling rod when the clamp operation longer for length is more difficult.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of device dismantling multisection type oil drill rocker, to overcome clamping section not easy-operating problem when inserting drilling rod of existing provision for disengagement.
The present invention's adopted technical scheme that solves the problem is: the device of dismounting multisection type oil drill rocker, comprise hydraulic base, hydraulic cylinder, holding ring, fastening devices, holding ring comprises the snap ring of two symmetrically arranged semicircle shapes, snap ring is provided with beginning and blind end, the blind end of the snap ring of two symmetries is connected by loose-leaf, the beginning of two snap rings is provided with junction plate, junction plate is provided with the tapped through hole coordinated with screw rod, nut, the inwall of snap ring is provided with flank, and the outer wall of snap ring is evenly provided with multiple fixed block.Because snap ring is provided with the beginning, when clamping drilling rod, first the beginning of snap ring is opened, by drilling rod by beginning insertion two snap ring, the beginning in snap ring is closed, tighten with nut again through after tapped through hole with screw rod, multiple screw rod and nut with the use of drilling rod well being fixed, the inwall of snap ring is provided with flank, flank has larger frictional force, the rotation of hydraulic cylinder promotion snap ring can be accomplished easily for those skilled in the art, snap ring rotates and drives drilling rod to rotate, thus drilling rod is split, flank makes snap ring inwall and drilling-rod external wall have resistance when rotating, avoid drilling rod to skid at snap ring inwall, and, be set to after fixed block be less than snap ring thickness in the axial direction, the present invention is by being set to the semicircle snap ring of two symmetries by holding ring, the blind end loose-leaf of two snap rings connects, beginning is connected with screw fit by screw rod, make the beginning of snap ring can open with closed freely, be convenient to the insertion of drilling rod, overcome clamping section not easy-operating problem when inserting drilling rod of existing provision for disengagement.
Further, the blind end of snap ring offers through hole, is provided with rotating shaft in through hole, and the two ends of rotating shaft are connected on the bearing of fastening devices.Such fastening devices can not have influence on the rotation that hydraulic cylinder drives snap ring.
Further, rotating shaft is arranged on the securing means by screw.Screw is detachable connected mode, is convenient to the replacing of snap ring, when snap ring changed by needs, directly fastening devices and rotating shaft is split, makes the replacing of snap ring more convenient.
Further, junction plate is welded on snap ring outer wall.The mode of welding is comparatively firm, avoids the phenomenon that when two snap rings close, generation junction plate comes off, improves stability when two snap rings close.
Further, the thickness of junction plate is set to 20mm-30mm.This thickness guarantees stability when offering tapped through hole thereon, comparatively wastes time and energy when avoiding the waste of the excessive material caused of junction plate thickness simultaneously and offer through hole.
To sum up, the invention has the beneficial effects as follows:
1, the present invention is by being set to the semicircle snap ring of two symmetries by holding ring, the blind end loose-leaf of two snap rings connects, beginning is connected with screw fit by screw rod, make the beginning of snap ring can open with closed freely, being convenient to the insertion of drilling rod, overcoming clamping section not easy-operating problem when inserting drilling rod of existing provision for disengagement.
2, the present invention is by by connection detachable for rotating shaft on the securing means, improves the convenience that snap ring is changed.
