Description
Technical field
The utility model relates to the multi-functional polished rod eye of a kind of self-rotary, belongs to the mechanical oil recovery field.
Background technology
Onshore oil field all is that the bar oil production equipment is arranged in the oil exploitation process basically, because all there is deflection to a certain degree in the oil well well; More or less all there are bending to a certain degree in oil pipe and sucker rod, thereby in the bar oil recovery process is arranged, cause and inevitably produce eccentric wear between oil pipe and the sucker rod; This eccentric wear often concentrates on a certain section of a certain side of oil pipe and sucker rod; Long-term work makes and is worn at eccentric wear place pipe bar, even oil pipe is worn through, and sucker rod is rubbed.In addition; Sucker rod when work, the stress that in oil well, can run into various resistances and produce when moving up and down, the comprehensive function result of these power can make sucker rod produce the circular motion of certain angle; Usually cause sucker rod generation back-off, dropout phenomenon; Need the stopping production well workover, directly influence crude oil production, increase lifting expenses.How to prevent the eccentric wear of oil pipe and sucker rod, prolong the life-span of oil pipe and sucker rod, reduce production costs, become an important topic in the oil exploitation.
At present; The measure that prevents the eccentric wear of oil pipe and sucker rod has three major types: rotation well head, impacting type rod rotor and differential rod rotor; They have solved the side-abrasion of rod string problem to a certain extent, but all have other shortcoming, influence result of use.The rotation well head has increased the wearing and tearing to sleeve pipe when avoiding the oil pipe eccentric wear; Impacting type rod rotor noise is big, and mechanical wear is big, and the life-span is short; It is bigger that differential rod rotor is influenced by liquid level then.In addition, existing rod rotor can't the installed load sensor, can not measure indicator card.
The utility model content
In view of the problems referred to above that exist in the prior art; The main purpose of the utility model is to address the deficiencies of the prior art; Provide a kind of self-rotary multi-functional polished rod eye; Be mainly used in and prevent side-abrasion of rod string in the pumping production,, can prevent effectively that oil pipe and sucker rod from producing eccentric wear, dropout phenomenon through the structure design that the utility model is optimized.
In order to address the above problem, the utility model provides a kind of self-rotary multi-functional polished rod eye, comprises compositions such as polished rod eye housing, Worm and worm-wheel gearing, anti-contrary ratchet and pawl arrangement, between each tumbler and polished rod eye housing bearings is housed.
Preferably, the multi-functional polished rod eye of said self-rotary is equipped with load transducer between thrust ball bearing and upper cover plate.
Preferably, said Worm and worm-wheel gearing, anti-contrary ratchet and pawl arrangement etc. is installed in the polished rod eye enclosure interior, and worm shaft stretches out the polished rod eye housing, is connected with large ratchet at axle head.
Preferably, said bearing gland adopts spline to be connected with worm-wheel shaft, and bearing gland can endwisely slip on worm-wheel shaft.
Compared with prior art, advantage of the utility model and beneficial effect are:
1. the multi-functional polished rod eye of self-rotary drive sucker rod when rotation rotates together, makes on even distribution of wearing and tearing and the circumference, has reduced eccentric wear.
2. the multi-functional polished rod eye direction of rotation of self-rotary is the sucker rod direction that links closely, and has anti-dropout function.
3. rotating speed has adjustable.
4. performance is safe and reliable, and does not hinder the operation task that measures indicator card.
5. compact conformation, volume is little, and is in light weight, is convenient to install, dismounting, adjustment.

Fig. 1, Fig. 2 are the structural representation of the utility model, and wherein, Fig. 1 is the top plan view of utility model, and Fig. 2 is the right pseudosection of Fig. 1.
Among the figure, 1-polished rod eye housing, 2-worm gear, 3-cover screw, 4-load transducer; The 5-thrust bearing, 6-bearing gland, 7-roller thrust block, 8-worm-wheel shaft, 9-ratchet assembly; The 10-worm screw, 11-upper cover plate, 12-ratchet, the anti-contrary ratchet of 13-, 14-taper roll bearing; The 15-radial ball bearing, 16-spacer pin, 17-pull bar, 18-stay cord.
The specific embodiment
To combine accompanying drawing and specific embodiment that the utility model is described further below.
The utility model provides a kind of self-rotary multi-functional polished rod eye.
Like Fig. 1, shown in Figure 2, the utility model comprises polished rod eye housing (1), worm gear (2), worm screw (10), anti-contrary ratchet (13), ratchet assembly (9) and load transducer (4) etc.Worm gear (2) worm screw (10) transmission device, anti-contrary ratchet (13) ratchet (9) etc. are installed in polished rod eye housing (1) inside, and worm screw (10) axle one end stretches out polished rod eye housing (1) and is connected with large ratchet (12), worm gear (2) and worm screw (10) the realization deceleration transmission of intermeshing.Between thrust ball bearing (5) and upper cover plate (11), load transducer (4) is housed, worm-wheel shaft (8) upper end is stretched out polished rod eye housing (1) and is adopted spline to be connected with bearing gland (6), so that sucker rod load is added on the load transducer (4) fully.The end of worm screw (10) is fixed with rod assembly (17), and the other end is connected with anti-contrary ratchet (13), and its ratchet assembly (9) is installed on the upper cover plate (11).The effect one of anti-contrary ratchet (13) is to prevent worm screw (10) reverse; The 2nd, make worm shaft two ends stress equalization, strengthen the rigidity of worm screw.The two ends of worm screw are connected with housing with taper roll bearing (14), improve the supporting capacity of worm screw.Realize rotating the unidirectional intermittence of worm screw (10) through the effect of anti-contrary ratchet (13) with ratchet assembly (9), worm-wheel shaft (8) drives bearing gland (6) and rotates together, finally makes sucker rod produce unidirectional low-angle intermittently and rotatablely moves.The multi-functional polished rod eye direction of rotation of self-rotary is the sucker rod direction that links closely, and has anti-dropout function.Worm screw one end is connected with housing with rolling bearing, and ratchet (13) is prevented back in installation in the end.
As a kind of preferred version of the utility model, the multi-functional polished rod eye of self-rotary is equipped with load transducer (4) between thrust ball bearing (5) and upper cover plate (11).
