Abstract
The invention relates to oil pumping rod clamp, which comprises two opposite clamps connected via the bolt. Wherein, the bolt cap is hinged with the clamps and relative to the groove and clamp mouth of said clamps, while the part of one side bolt through the clamp is a groove and the part of the upper part of connection bolt through the clamp is the through hole. The whole clamp is integrated as a whole with easy operation. The relative clamp is embedded with the clamp sheath and sphere clamp sheath at best, while the clamp surface with sphere clamp sheath is non-continuous smooth surface and the clamp mouth and the oil pumping rod have uniform multi-point connection.
Description
Technical field: pumping rod fasterner is the clamp of the sucker rod of oil pump.
Background technology: existing pumping rod fasterner, two relative chucking bodies are arranged, the chucking body connects by bolt.Turn on bolt, bolt all will separate with the chucking body, installs and clamp very inconvenient once more.If original product is subjected to bigger moment of flexure effect with bolt and the random hinge of chucking body during work, clamping force is reduced, even chucking was lost efficacy, the bayonet socket of chucking body is a cambered surface, the bayonet socket arc deformation will be to the unbalance stress of bar when bolt was tightened.The chucking face of the chucking cover that has in addition very easily makes pole face be squeezed and bursts, and this is the fatal shortcoming of original structure.So there is following problem technically in existing product: structure is very unreasonable, and the bar unbalance stress has by the crowded phenomenon of bursting; Inconvenient operation, dangerous.
Summary of the invention:
It is very unreasonable that the present invention solves structure exactly, inconvenient operation problem and to the problem of sucker rod unbalance stress, a kind of rational in infrastructure, easy to operate pumping rod fasterner is provided, further provides the sucker rod stress balance, do not have by the pumping rod fasterner of the crowded phenomenon of bursting.
Pumping rod fasterner of the present invention, two relative chucking bodies are arranged, the chucking body connects by bolt, it is characterized in that: bolt emits and chucking body hinge connection and corresponding with the open slot and the bayonet socket of chucking body, wherein a side bolt passes the chucking position and is changed to open slot, and the position that the chucking body is passed on the connecting bolt top of opposite side is a through hole.Bolt is connected through the hinge with the chucking body like this, behind the nut that loosers a bolt, wherein a side bolt is swung away from chucking body open slot around hinged bearing pin, the connecting bolt of opposite side is around hinged bearing pin swing, its top is gone up the chucking body by the through hole drive of chucking body and is opened, and just can take off pumping rod fasterner.Because bolt is all hinged with the chucking body, one of them bolt is being connected with last chucking body by through hole, and each several part can not separate to be lost; And these assemblies are stuck in sucker rod, and just can merge the chucking body smoothly, the bolt of a side is gone into open slot, fastening nut just is assembled into sucker rod with pumping rod fasterner easily, and operation is very easy.Two relative bayonet sockets of relative chucking body generally all are inlaid with the chucking cover, and the chucking cover that two relative relative bayonet sockets of chucking body are inlayed and chucking body preferably spherical crown surface are connected.Chucking that such two relative chucking bodies are inlayed cover outside has easy generation centripetal force for spherical, and two relative chuckings cover inner faces are preferably with groove in length and breadth, makes the chucking cover contact chucking, easier equilibratory centripetal force with the beam hanger distribution.The chucking face of the sphere chucking cover that the relative bayonet socket of chucking body is inlaid with is discontinuous light face, and bayonet socket contacts with the multiple spot that sucker rod is evenly distributed.Be that bayonet socket still is that uniform multiple equilibrium contacts with sucker rod after clamping distortion like this, guarantee can not occur to be squeezed the phenomenon of bursting.Simultaneously convenient in order to install and to take off, the chucking body back side has handle.
The present invention compared with the prior art, it is even to have a clamping force, does not injure the beam hanger surface, easy and safe to operate.
Description of drawings: accompanying drawing has been represented a kind of pumping rod fasterner structural representation of the present invention, and wherein Fig. 1 is main sectional view, and Fig. 2 is left sectional view.Example below in conjunction with accompanying drawing further specifies.
Specific embodiment: this pumping rod fasterner of the present invention as shown in drawings, by chucking body 4 and 7, hinge bolt 2, compositions such as chucking cover 5 and handle 8.Hinge bolt and following chucking body are hinged 1, and wherein the left side bolt passes the chucking position and is changed to open slot, and the position that the chucking body is passed on the connecting bolt top on right side is a through hole, forms with last chucking body direct-connected.Whole like this jig becomes conjoined structure, on tighten body can be around hinge through, easy to use.When merging clamping work, bolt emits and is stuck in down the chucking body, and hinge pin does not stress.Last chucking body left-hand end is an open slot, and is convenient when bolt is packed into.Chucking cover outside closely cooperates for spherical structure and with chucking body hemisphere 6 inner faces, the inboard chucking face of chucking cover is discontinuous light face, is to have translot of a pod at semi-cylindrical, makes the bar multiple spot stressed, increase clamping force, and can not squeeze the surface of the bar of bursting.Spherical has Self-centering Action, not only makes bar stressed evenly and bear bi-directional axial power, does not have directionality during use.To tighten body up and down during use and be connected as a single entity by hinge bolt, and suitably loosen according to the size of bar, and simultaneously the bolt in left side be set level, and determine to be placed in the open slot behind the clamped position again, one hand-held handle tights a bolt 3 on the other hand during operation, promptly convenient safety again.
Claims (5)
1, a kind of pumping rod fasterner, two relative chucking bodies are arranged, the chucking body connects by bolt, it is characterized in that: bolt emits and chucking body hinge connection and corresponding with the open slot and the bayonet socket of chucking body, wherein a side bolt passes the chucking position and is changed to open slot, and the position that the chucking body is passed on the connecting bolt top of opposite side is a through hole.
2, as the said pumping rod fasterner of claim 1, it is characterized in that: the chucking cover that two relative relative bayonet sockets of chucking body are inlayed is connected with chucking body spherical crown surface.
