Abstract
A pumping rod housing lock joint of a screw pump is primarily used to resolve the problem that the current screw pumping rod joint is easy to release. The utility model is characterized in that the ends of the upper and the lower rod (1,2) are separately provided with a polyhedral (3) and a built-in matched hole (4) in the polyhedral (3), and the outside at the end of the upper and the lower rod (1,2) is connected to a barrel (5). The release phenomenon caused by the threading connection is avoided.
Description
Technical field:
The utility model relates to oil recovery field, oil field used screw pump accessory, especially screw pump sucker rod anti-tripping joint.
Background technique:
The means that mechanical oil recovery recovers the oil now as the oil field, contain husky aboveground employing screw pump at especially sticking at height, gassiness.Screw pump mainly drives pump by drive unit by sucker rod and rotates, reach the purpose of oil pumping, and because of connection between the sucker rod is by being threaded, when rotating, because the screw pump sucker rod is subjected to bigger moment of torsion, and the more serious torsional vibration of existence, there is the instantaneous phenomenon that releases, causes mill button, strip button and dropout, finally cause the workover workload to increase, cause pump to damage when serious, influence ordinary production.
The model utility content:
In order to overcome the deficiency that existing screw pump rod connector is easily threaded off, the utility model provides a kind of screw pump sucker rod anti-tripping joint, and this screw pump sucker rod anti-tripping joint has solved the dropout phenomenon that causes because of being threaded and produced.
The technical solution of the utility model is: this screw pump sucker rod anti-tripping joint comprises upper boom and lower beam, and last lower beam one termination has polyhedron and the built-in identical hole of polyhedron respectively, up and down the outer coupling sleeve of rod end head.
Above-mentioned face body is 6.
The beneficial effect that the utlity model has is: because the lower beam termination of screw pump sucker rod anti-tripping joint is hexahedron or spline, and hole corresponding with lower beam or cover are arranged under the stage of upper boom termination, moment of torsion can transmit by them, having solved the dropout phenomenon that produces because of being threaded produces, knock-off joint connects by internal thread of sleeve up and down simultaneously, transmits pulling force, has guaranteed axial connection, so just reduce the workover workload, improved the efficient of screw pump.
Description of drawings:
Accompanying drawing 2 is the utility model A-A sectional drawings.
1-upper boom among the figure, 2-lower beam, 3-polyhedron, 4-hole, 5-sleeve.
Embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By Fig. 1 in conjunction with shown in 2, this screw pump sucker rod anti-tripping joint comprises upper boom 1 and lower beam 2, there are 6 bodies 3 upper boom 1 one terminations, lower beam 2 one terminations have and polyhedron 3 built-in identical holes 4, upper boom 1 phase deck is in lower beam 2, moment of torsion can transmit by them, has solved the dropout phenomenon that produces because of being threaded and has produced; By the sleeve 5 that is threaded, transmit pulling force outside last lower beam (1, the 2) termination, guaranteed axial connection, so just reduced the workover workload, improved the efficient of screw pump.
Claims (2)
1, a kind of screw pump sucker rod anti-tripping joint, comprise upper boom (1) and lower beam (2), it is characterized in that: going up lower beam (1, a 2) termination has polyhedron (3) and the built-in identical hole of polyhedron (3) (4) respectively, coupling sleeve (5) outside last lower beam (1, the 2) termination.
2, screw pump sucker rod anti-tripping joint according to claim 1, it is characterized in that: polyhedron (3) is 6.
