The device mainly comprises a universal joint, flexible shafts, spherical surface pressing caps, steel balls, pressure bearing ball seats, filter screens, filter screen plugs and female buckle joints, wherein the pressure bearing ball seats are symmetrically mounted at the two ends of the universal joint; one ends of the flexible shafts are connected with the female buckle joints through threads, and the other ends are connected with the pressure bearing ball seats and the spherical surface pressing caps through spherical surfaces; the spherical surface pressing caps are fixed on the universal joint through threads; and the spherical surfaces at the ends of the flexible shafts are axially fixed in the universal joint through the pressure bearing spherical surfaces and the spherical surface pressing caps.
Description
Technical field
The present invention relates to a kind of oil recovery downhole tool, particularly a kind of ground drives lower curved section pumping rod universal joint formula linkage in oil-extracting screw pump well.
Technical background
At present on oil field, ground drives oil-extracting screw pump to be widely used in Vertical Well, and applies less in horizontal well and inclined shaft, mainly drives in oil-extracting screw pump well on ground and lacks lower curved section universal joint linkage.Ground drives lower curved section pumping rod universal joint formula linkage in oil-extracting screw pump well to connect the sucker rod that two are mutually certain angle, the moment of torsion that top sucker rod provides is passed to bottom sucker rod, bottom sucker rod is born simultaneously along body of rod direction pull transfer to top sucker rod, this device should transmitting torque, bears pulling force or pressure again simultaneously.At present, the ball contact universal drive shaft and the Petal type cardan axle etc. that use in the oil industry all can only bear pressure and can not bear pulling force while transmitting torque.
Summary of the invention
The object of this invention is to provide and a kind ofly not only transmitting torque but also the ground can bearing axial tension or pressure can drive lower curved section pumping rod universal joint formula linkage in oil-extracting screw pump well, pass through the technical program, separatedly in employing perturb axle, to perturb axle by end sphere pressure cap and pressure-bearing ball seat is axially fixed in gimbal joints, solve ball contact universal joint can only bear pressure and the problem of pulling force can not be born, to make up the deficiencies in the prior art while transmitting torque.
For achieving the above object, the technical solution used in the present invention is:
A kind of ground drives lower curved section universal joint linkage in oil-extracting screw pump well, and its structure mainly comprises: gimbal joints, perturb axle, sphere pressure cap, steel ball, pressure-bearing ball seat, filter screen, filter screen core plug, female connector; Described gimbal joints two ends symmetry installs described pressure-bearing ball seat; The described axle one end that perturbs is connected with female connector by screw thread, and the other end is connected with described sphere pressure cap with pressure-bearing ball seat by sphere, and described sphere pressure cap is fixed in gimbal joints by screw thread; The described shaft end sphere that perturbs is axially fixed in described gimbal joints inside by pressure-bearing sphere and sphere pressure cap.
Described ground drives lower curved section universal joint linkage in oil-extracting screw pump well, and described gimbal joints end inner headed face is evenly distributed with several open semi arc grooves, described in perturb shaft end spherical uniform distribution and have several ball-and-sockets; Described steel ball distribution is arranged on the half-arc groove on the inner headed face of gimbal joints end and perturbs in the ball-and-socket on shaft end sphere.
Described ground drives lower curved section universal joint linkage in oil-extracting screw pump well, described female connector two ends are threaded connection and both can be connected and also can connect by sucker rod with the described axle that perturbs, and can realize ground and drive the multistage of lower curved section Universal joint connector in oil-extracting screw pump well freely to connect.
Beneficial effect of the present invention:
Pass through the technical program, not only realize ball contact universal coupling to perturb axle can bear axial compression but also can axial tension be born while transmitting torque, realized the independent assortment of multi-stage ball contact universal coupling by end female connector, well meet ground and drive the needs that on oil-extracting screw pump well lower curved section, lower sucker rod connects.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated:
The present invention is as Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, gimbal joints 2 two ends are provided with pressure-bearing ball seat 6, the end perturbing axle 8 is connected with female connector 1 by screw thread, other end sphere is axially fixed in gimbal joints 2 by pressure-bearing ball seat 6 and sphere pressure cap 7, steel ball 3 is arranged on the half-arc groove on the inner headed face of gimbal joints 2 end and perturbs in the ball-and-socket on the sphere of axle 8 end, steel ball 3 can axially-movable in the half-arc groove on the inner headed face of gimbal joints 2 end, perturb axle 8 by steel ball 3 transmitting torque, perturb axle 8 simultaneously and can realize eccentric motion by the axially-movable in the half-arc groove of steel ball 3 on the inner headed face of gimbal joints 2 end.Female connector 1 two ends are threaded connection and both can be connected and also can connect by sucker rod with the described axle 8 that perturbs, and can realize ground and drive the multistage of lower curved section Universal joint connector in oil-extracting screw pump well freely to connect.
The above, be only a kind of embodiment of the present invention, not deliberately for limiting protection scope of the present invention.
