Description

Perpendicular walking beam steel band type long stroke pumping unit
Technical field:
The utility model relates to a kind of perpendicular walking beam steel band type long stroke pumping unit, belongs to the oil extraction machinery and equipment design field.
Background technology:
At present, the oil recovery machiner equipment of China's extensive use is the horizontal beam pumping units of four connecting rods.The advantage of this oil pumper be simple in structure, sturdy reliable, be suitable for open-air all weather operations, its shortcoming is because the restriction of walking beam forearm length and walking beam pivot angle is difficult to obtain long stroke.But, adopt the operating mode of long stroke, low jig frequency more to help improving pump efficiency because the problem of China's thickened oil recovery is more outstanding.So both can increase production, can save energy again, and, also can prolong the application life of oil pumper significantly because of the stress-number of cycles of each parts in the unit interval greatly reduces.In order to adapt to this requirement, China has developed the multiple extraordinary oil pumper that can increase stroke.These oil pumpers are divided into beam pumping unit and the tower shelf type oil pumping machine two big classes that increase stroke substantially.But generally speaking, the stroke of the beam pumping unit of growth stroke is still big inadequately, and generally in 4.8 meters, tower shelf type oil pumping machine can obtain bigger stroke, but the reliability of its reversing arrangement is generally not high, is easy to damage.
In the above-mentioned various long stroke pumping unit, the oil pumper that the application multi-bar linkage obtains long stroke increases because of driving-chain, and mechanical efficiency descends to some extent.In addition, also can because of make, the deficiency of installation accuracy, make some passive constraint become real constraint, cause correlated parts to produce distortion be installed, thereby its stress is sharply raise and damage.And the length of stroke that existing increase stroke beam pumping unit can be realized is still big inadequately.Tower shelf type oil pumping machine can obtain bigger stroke, but the reliability of its reversing arrangement is not high.Therefore also be necessary to develop and a kind ofly can realize long stroke, energy-efficient again, as to have high reliability oil pumper satisfies and adapts to the actual demand of producing.
Summary of the invention:
The purpose of this utility model is to provide a kind of perpendicular walking beam steel band type long stroke pumping unit, makes it to realize long stroke, and is energy-efficient again, has characteristics simple in structure, that operational reliability is high.
The utility model is achieved through the following technical solutions above-mentioned purpose.
In the structure of perpendicular walking beam steel band type long stroke pumping unit, be provided with motor (1), Belt Transmission (2), reducer support (3), gear reduction unit (4), crank (5), connecting rod (6), walking beam support (7), beam counterweight (8), walking beam (9), steel band (10), directive wheel (11), wellhead assembly (12), directive wheel support (13) etc., one end of one end of connecting rod (6) and crank (5) is hinged, and the other end of connecting rod (6) is then hinged with the middle part of walking beam (9); The lower end of walking beam (9) is connected through the hinge on walking beam support (7), and its upper end is hinged with steel band (10); One end of steel band (10) is connected with the upper end of walking beam (9), and the other end is walked around and passed wellhead assembly (12) behind the directive wheel (11) and be connected with oil pump plunger piston; An end out-phase fixing at walking beam (9) and walking beam support (7) hinge is equipped with beam counterweight (8).
The utility model compared with prior art has following beneficial effect:
1, simple in structure, support is short, consume that steel are few, cost is low, and is easy to install, and can obtain 4~8 meters long stroke easily.
2, reduced down-hole load, mechanical efficiency height, good reliability.
3, the balance weight position is low, is easy to adjust, and counterbalance effect is better, can obtain good energy-saving effect.
Description of drawings:
Fig. 1 is the general structure schematic diagram of perpendicular walking beam steel band type long stroke pumping unit.
In the drawings: 1. motor, 2. Belt Transmission, 3. reducer support, 4. gear reduction unit, 5. crank, 6. connecting rod, 7. walking beam support, 8. beam counterweight, 9. walking beam, 10. steel band, 11. directive wheels, 12. wellhead assemblies, 13. directive wheel supports.
The specific embodiment:
This perpendicular walking beam steel band type long stroke pumping unit is made up of motor (1), Belt Transmission (2), reducer support (3), gear reduction unit (4), crank (5), connecting rod (6), walking beam support (7), beam counterweight (8), walking beam (9), steel band (10), directive wheel (11), wellhead assembly (12), directive wheel support (13) etc., and the high speed rotating of motor (1) makes the output shaft of gear reduction unit (4) obtain to slowly run after drive belt (2) and gear reduction unit (4) deceleration; The output shaft of one end of crank (5) and gear reduction unit (4) connects firmly, and an end of crank (5) other end and connecting rod (6) is hinged; One end of one end of connecting rod (6) and crank (5) is hinged, and the other end of connecting rod (6) is then hinged with the middle part of walking beam (9); The slowly running of gear reduction unit (4) output shaft promotes walking beam (9) by crank (5) and connecting rod (6) and makes reciprocally swinging, and the steel band (10) that is connected with the upper end of walking beam (9) is walked around and passed wellhead assembly (12) behind the directive wheel (11) and be connected with oil pump plunger piston.Therefore, the reciprocally swinging of walking beam (9) can drive downhole pump work.Walking beam (9) is vertically arranged, and position of the fulcrum is lower, and the length of whole walking beam is the radius of gyration of the towing point of steel band (10), so can obtain very big length of stroke; An end out-phase fixing at walking beam (9) and walking beam support (7) hinge is equipped with beam counterweight (8), and it can be used for the gravitational moment of balance portion down-hole load and walking beam, so that the moment of torsion of gear reduction unit output shaft tends to be steady; The transmission device of being made up of motor (1), Belt Transmission (2), gear reduction unit (4) etc. is positioned between walking beam (9) and the directive wheel support (13), like this when oil pumper is in lower dead point position, this moment, the oil pump plunger piston commutation was up, the suffered load of steel band is near maximum value, the drive line angle of mechanism is also near 90 °, so transmission force property is excellent at this moment.
