Description
Technical field
The utility model provides the oil production equipment of mechanical field, specifically a kind of sucker rod guide.
Background technology
Before the utility model proposes, sucker rod interconnect normally that pipe collar or connecting thread realize with connecting.When upper and lower reciprocating action of the sucker rod that this connected mode made up or spinning movement, higher to the concentricity requirement of wellhole, when concentricity is relatively poor, causes the excessive friction of the sucker rod part and the borehole wall easily and cause sucker rod breakage, reduction of service life.Particularly when wellhole had big gradient, the sucker rod that this connected mode made up can not normally use.
Summary of the invention
In order to overcome the shortcoming that existing pumping rod connecting device is not suitable for carrying out the inclined shaft operation, the utility model provides a kind of sucker rod guide.This kind guider can realize that automation curve dynamically connects the transmission of the stick force of pumping, thereby, can adapt to the big or oil pumping operation of inclined shaft of curvature.
The technical scheme in the invention for solving the technical problem is: be connected with the guider shell on the sucker rod connector, in the guider shell, be provided with the guider groove, guider ring cavity and guider locking closure screw thread, by the guider locking closure guider screw thread locking closure that has been threaded, in guider screw thread locking closure, be provided with guider screw thread locking closure negative camber ball-and-socket, by the guider groove, in guider ring cavity and the formed space of guider screw thread locking closure negative camber ball-and-socket the axis of guide is housed, the axis of guide is provided with axis of guide plush copper near guider groove one side, and be connected with axis of guide screw rod with axis of guide curved surface bulb, axis of guide screw rod is connected with shaft joint, is provided with shaft joint card face in the shaft joint outside.The sucker rod connector can be check ring joint structure or screw connection structure.Check ring joint structure is provided with sucker rod connector snap ring, and the sucker rod connector of screw connection structure is provided with sucker rod connector screwed hole.Connect and compose sucker rod guide of the present utility model with shaft joint rightabout symmetry respectively at the guider that constitutes by sucker rod connector, guider shell and the axis of guide.
Owing to be provided with guider groove, ring cavity and guider screw thread locking closure negative camber ball-and-socket in the guider shell of the utility model guider, and in its formed cavity the corresponding axis of guide that constitutes by axis of guide plush copper, axis of guide curved surface bulb and axis of guide screw rod that is equipped with, can realize the transmission of power when the sucker rod axle center is not on a concentric line, thereby, can adapt to deflecting well oil withdrawal operation with axle center curvature.And simple structure, easy to connect, long service life.Be suitable for lifting or rotating the oil pumping operation of vertical or inclination oil well.

The specific embodiment
According to Fig. 1～shown in Figure 6: on sucker rod connector 1, be connected with guider shell 2, in the guider shell, be provided with guider groove 2a, guider ring cavity 2b and guider locking closure screw thread 2c, by the guider locking closure guider screw thread locking closure 3 that has been threaded, in guider screw thread locking closure, be provided with guider screw thread locking closure negative camber ball-and-socket 3a, by the guider groove, in guider ring cavity and the formed space of guider screw thread locking closure negative camber ball-and-socket the axis of guide 4 is housed, the guider axle is provided with axis of guide plush copper 4a near guider groove one side, and be connected with axis of guide screw rod 4c with guider curved surface bulb 4b, axis of guide screw rod is connected with shaft joint 5, is provided with shaft joint card face 5a in the shaft joint outside.The sucker rod connector can be check ring joint structure shown in Figure 5 or is screw connection structure shown in Figure 6.Check ring joint structure is provided with sucker rod connector snap ring 1a, and the sucker rod connector of screw connection structure is provided with sucker rod connector screwed hole 1b.Connect and compose sucker rod guide of the present utility model with shaft joint rightabout symmetry respectively at the guider that constitutes by the guider shell and the axis of guide.
Guider groove and axis of guide plush copper end face can be structure shown in Figure 2, and its end surface shape can be rectangle, square, triangle, hexagon, octagon etc. and has the shape that the edge is faced directly.
The shaft joint card face of shaft joint can adopt one group of symmetrical plane shown in Figure 4 or organize symmetrical plane more.
The utility model course of work: when the sucker rod guide made by technical solutions of the utility model is used for pumping operation after sucker rod connects, can realize that upper and lower shift reciprocately is used for pull-type oil pumping operation.When this duty, formation reciprocating force transmission mechanism contacts between the set axis of guide curved surface bulb on set guider screw thread locking closure curved surface ball-and-socket and the axis of guide in the guider screw thread locking closure in the guider.The sucker rod that guider is housed when the utility model is during as rotation oil pumping operation, is located at the transmission that guider groove and the axis of guide plush copper plane on being located at the axis of guide in the guider shell acts on the realization revolving force mutually.When the axle center between the sucker rod not point-blank the time, just under the state of off-centre, axis of guide plush copper and guider groove are offset in ring cavity, be subjected to the position-limiting action of guider screw thread locking closure ball-and-socket, the rotation sphere of axis of guide curved surface bulb also is offset, and has realized the transmission of both revolving forces under the state of decentraction and the automatic location of sucker rod.
