Abstract
The utility model provides a sucker rod turning gear, which belongs to the accessory of the sucker machine in the oil field, and mainly solves the problems of partial abrasion, vibration, buckle falling and reliable work of the sucker rod. The sucker rod turning gear comprises a quadrate fastener for fixing the sucker rod, a pressing cover, a locking mechanism, a turning mechanism and an energy accumulating gear. The utility model is characterized in that an antislid groove is arranged on the lower cone surface of the locking mechanism; a spline groove is arranged on the arc surface of the locking mechanism contacted with the sucker rod. An antislid pin cooperated with the antislid groove on the cone surface of the locking mechanism is arranged on the groove surface of a turning shaft. The turning shaft and a turning wheel in the turning mechanism adopt the one-way clutch; the external side of the turning wheel is symmetrically provided with a pair of guide bearings. The guide bearings are positioned in a guide groove arranged according to the set direction in the internal wall of a casing. The energy accumulating gear is a disc shape spring. The utility model can effectively solve the problems of partial abrasion, buckle falling and vibration in the working process of the sucker rod, increasing the reliability of the work and being easy for popularizing in the oil field.
Description
Technical field
The utility model belongs to the oil-field oil pumper annex, and a kind of oil field sucker rod whirligig mainly is provided.
Background technology
In use there are some problems in the sucker rod of existing oil pumper, as: because the oil oil reservoir is darker, thus the well depth of oil well also all more than km, sucker rod is longer.The axiality of sucker rod and pit shaft just can't definitely be guaranteed, in oil pumping process the off-set phenomenon of sucker rod and pit shaft will take place thus and rubs.Always at a position, time length will leakage take place and sucker rod is broken for this eccentric wear.Second problem is that for easy to install and use, sucker rod is made up of the more piece thread connection because sucker rod is very long.Sucker rod is operation up and down for a long time, and sucker rod is threaded off easily.This phenomenon often takes place at oil well.The 3rd problem is that oil pumper can produce sudden load change in oil recovery process, influences work safety.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of sucker rod whirligig, and it not only solves eccentric wear effectively, shake, reach the problem of threading off, and reliable operation.
The utility model is finished the technical scheme that its invention task taked: comprise being positioned at the fixedly gland of the square clamp below of sucker rod, the gland below is retaining mechanism and rotating mechanism, the below of rotating mechanism is an energy storage equipment, the following conical surface that it is characterized in that described retaining mechanism is provided with anti-slip tank, and the cambered surface that retaining mechanism contacts with sucker rod is provided with spline; On the rotating shaft groove face, be provided with the anti-sliding pin that matches with retaining mechanism conical surface anti-slip tank; Adopt one-way clutch between described rotating mechanism shaft and the runner, be arranged with a pair of guide bearing on the runner outside, described guide bearing is positioned at the gathering sill by the direction initialization setting of inner walls; Described energy storage equipment is a disk spring.
The operating principle of sucker rod whirligig is to utilize sucker rod to pump doing, because the load difference of uplink and downlink carrying, produce a load difference, the energy that this load difference produces is when this installs, axial displacement is converted into radially rotation, thereby promotes the unidirectional rotation of sucker rod.
During work, oil pumper makes sucker rod do upper and lower reciprocating action, and when sucker rod moved downwards, the square clamp of whirligig top compressed whirligig, make retaining mechanism clamp sucker rod, when descending, the pressure that whirligig is subjected to is less, only pressurized but distortion of butterfly spring, can not realize rotation, this moment, retaining mechanism only played the effect of another square clamp, and the accumulation of energy of butterfly spring pressurized can prevent the load sudden change.
When sucker rod upwards moves, the whirligig pressurized strengthens, the butterfly spring compressive deformation forces runner to move downward along gathering sill, drive runner and retaining mechanism and sucker rod simultaneously and clockwise rotate certain angle, ceaselessly clockwise direction rotation of sucker rod like this, the dropout problem of the eccentric wear of oil well and sucker rod and sucker rod is resolved.
The utility model structure design is advantages of simple comparatively, can effectively solve the eccentric wear that sucker rod exists in the course of the work, threads off and vibration problems.Improved the reliability of work.Concrete effect:
1, prevent eccentric wear: the energy that this device utilizes sucker rod uplink and downlink load difference to produce, promote the sucker rod rotation voluntarily, make the wearing and tearing of sucker rod and tube wall become more even, thereby prolonged the cycle of workover treatment, reduced the well maintenance expense.
2, prevent sudden load change: this device adopts high-quality disk spring as absorbing and discharge the energy that sucker rod uplink and downlink load difference produces, absorptivity reaches 80%-90%, improve the STRESS VARIATION of sucker rod greatly, also reduced the infringement and the accident that oil pumper are caused because of sudden load change.
3, prevent pumping rod disengaging:, make rod connector be in tight condition all the time, thereby prevented the dropout accident of sucker rod because this device promotes sucker rod all the time and does unidirectional rotation.
4, reliable operation: the following conical surface of retaining mechanism is provided with anti-slip tank, and the cambered surface that retaining mechanism contacts with sucker rod is provided with spline; On the rotating shaft groove face, be provided with the anti-sliding pin that matches with retaining mechanism conical surface anti-slip tank.This kind anti-skid structure makes realizes the effective power transmission between locking mechanism and rotational structure and the sucker rod, avoid skidding because of grease exists.
Description of drawings:
Figure is the utility model master sectional view.
Among the figure: 1 gland, 2 case lid, 3 retaining mechanisms, 4 guide bearings, 5 rotating shafts, 6 runners, 7 bearings, 8 bearing supports, 9 butterfly springs, 10 housings.
The specific embodiment
As shown in the figure, this sucker rod whirligig comprises being positioned at the fixedly gland 1 of the square clamp below of sucker rod that gland 1 below is that retaining mechanism 3 links to each other with rotating mechanism, the below of rotating mechanism is an energy storage equipment, and this kind polished rod eye layout type is open in the prior art.
Be as contribution of the present utility model:
Retaining mechanism 3 is made up of two halves and is coated sucker rod, and its top be a gland 1, and the top of gland 1 is the fixing square clamp on the sucker rod.Adopt one-way clutch between rotating mechanism shaft 5 and the runner 6, be arranged with a pair of guide bearing 4 on runner 6 outsides, described guide bearing 4 is positioned at the gathering sill by the direction initialization setting of housing 10 inwalls.Rotating shaft 5 upsides are provided with conical surface groove, the following cone match of this conical surface groove and retaining mechanism 3, and the groove face of aforementioned conical surface groove is provided with anti-sliding pin, and the following conical surface of aforementioned retaining mechanism 3 is provided with anti-slip tank, but anti-sliding pin above-below direction in anti-slip tank slides.
The bearing 7 and the sleeve type bearing seat 8 that are used for bearing load and reduce friction are positioned at butterfly spring 9, and butterfly spring 9 is positioned at housing 10, and its accumulation of energy effect is more satisfactory.
Mounting method of the present utility model is basic identical with existing polished rod eye technology.
