Description
One, technical field
The present invention relates to a kind of oil exploration equipment, particularly is the beam pumping unit of driving force with linear electric motors.
Two, prior art
Beam pumping unit is widely used a kind of oil exploration equipment on the present oil field, and its rational structure makes it be fit to on-the-spot rugged environment, and is durable in use, has very strong vitality.But it normally adopts electric rotating machine to drive by deceleration device, and also need adopt multi-form bascule during its work, so power consumption is big, and system effectiveness is low, the balance adjustment inconvenience, and have certain potential safety hazard.For this reason, people have carried out a large amount of research and test, particularly at aspects such as power transmission and type of drive, attempt to improve and improve the operating characteristic of beam pumping unit.Chinese patent 96217638.9 disclosed " oil pumper that adopts linear electric motors to drive ", Chinese patent 94108326 disclosed " method of the linear electric motors of pump at the bottom of the control well " and Chinese patent 99256966.4 disclosed " linear electric motors driving blue elephant " etc. have all carried out useful exploration from different perspectives, but also perfect not to the utmost, more or less also exist deficiency.
Chinese patent 02200403.3 discloses again on the basis of the above a kind of " the two horse head linear electric motors of beam type drive oil pumper ".Horse head connects lifting drive by wire rope after this scheme, and this device is cylindrical linear, and linear motor rotor is enclosed within the periphery of its stator, and mover links to each other with wire rope, pumps, and realizes the oil pumping operation.There is following deficiency in this scheme:
1, being connected to of linear electric motors and oil pumper is flexible coupling, and linear electric motors can only be subjected to play the driving effect under the situation of pulling force, and service efficiency is low, and can not in time realize brake or braking, increased system's unsafe factor;
2, because linear motor rotor is enclosed within the periphery of its stator, its maintenance and the inconvenience of replacing element;
3, directly drive processing, installation difficulty with cylindrical linear.
Three, summary of the invention
The beam pumping unit that the objective of the invention is to overcome the deficiency of prior art and provide a kind of linear electric motors easy to operate, safe and reliable, function admirable to drive.
Realize that the technical scheme that purpose of the present invention is taked is:
The present invention mainly is made up of in the support on the base, the walking beam that is articulated in cantilever tip, the horse head that is fixed in the walking beam two ends, lifting rope and polished rod eye and the control system etc. that hang on the horse head seat, the linear electric motors that drive beam pumping unit work mainly are made up of primary and secondary, its elementary employing platysome, secondary employing horse head.Described platysome inboard studs with winding, and the platysome lower end is fixed on the pedestal, and last middle part is fixed in the overhanging end of horizontal support.Horizontal support with as secondary horse head side plate opposite position the electromagnetic brake device is housed.Stud with permanent magnet as secondary horse head surface.Between described lifting rope and polished rod eye, be serially connected with sensor.
Platysome constitutes flute profile by three flat boards, only also can be to be made of the flat board as bottom land.The bottom land top that constitutes platysome also can be with as the secondary corresponding cambered surface of horse head cambered surface.Platysome also can be made of two parallel plates.
Mainly flat thin magnet, an end on the horizontal support is fixed in the bearing pin of flat thin magnet side to described electromagnetic brake device and the brake block that is placed on the bearing pin is formed by being fixed in, and its bearing pin is axially perpendicular to flat thin magnet and brake block, and promptly flat thin magnet is parallel with brake block.
Adopt technical scheme of the present invention can obtain following effect:
Because the present invention directly drives beam pumping unit with specific linear electric motors as power, original deceleration device and balance weight have been removed, drive disk assembly is few, complete machine is in light weight, easy for installation, safe and reliable, and can directly carry out running parameters such as step-less adjustment stroke and jig frequency by changing the linear electric motors running parameter, thus solved the situation of " low load with strong power ".

Five, embodiment
The invention will be further described below in conjunction with accompanying drawing.
Referring to accompanying drawing, the present invention mainly is made up of in the support on the base 1 11, the walking beam 6 that is articulated in support 11 tops, the horse head 5 and 8 that is fixed in walking beam 6 two ends, lifting rope 4 and polished rod eye 2 and the control system 10 etc. that hang on horse head 5 or 8 seat, the linear electric motors that drive beam pumping unit work mainly are made up of primary and secondary, its elementary employing platysome 13, secondary employing horse head 5 or 8.Described platysome 13 inboards stud with winding 15, and platysome 13 lower ends are fixed on the pedestal 12, and last middle part is fixed in the overhanging end of horizontal support 9.Horizontal support 9 with as secondary horse head 5 or 8 side plate opposite positions electromagnetic brake device 16 is housed.Stud with permanent magnet 7 as secondary horse head 5 or 8 surfaces.Between described lifting rope 4 and polished rod eye 2, be serially connected with sensor 3.
Mainly flat thin magnet 161, an end on the horizontal support 9 is fixed in the bearing pin 162 of flat thin magnet 161 sides to described electromagnetic brake device 16 and the brake block 163 that is placed on the bearing pin 162 is formed by being fixed in, its bearing pin 162 is axially perpendicular to flat thin magnet 161 and brake block 163, and promptly flat thin magnet 161 is parallel with brake block 163.
Referring to Fig. 2 to Fig. 8, platysome 13 constitutes flute profile (as Fig. 1 and Fig. 2) by three flat boards, only also can be to constitute (as Fig. 4 and Fig. 6) by the flat board as bottom land 14.Bottom land 14 tops that constitute platysome 13 also can be with as secondary horse head 5 or the corresponding cambered surface of 8 cambered surfaces (as Fig. 5, Fig. 7 and Fig. 8).Platysome 13 also can be made of (as Fig. 1 and Fig. 3) two parallel plates.
Fixedly the installed surface of the pedestal 12 of elementary platysome 13 lower ends of linear electric motors can be higher than the installed surface of the base 1 of fixed support 11 lower ends.
The sensor 3 that is serially connected with between lifting rope 4 and the polished rod eye 2 joins with control system 10.
Drive walking beam 6 as the secondary horse head 5 or 8 of linear electric motors and do circular arc reciprocating motion up and down, thereby lifting rope 4 and polished rod eye 2 are pumped, realize the oil pumping operation around support 11.
Operating principle of the present invention:
When linear electric motors elementary was platysome 13 energisings, the winding 15 in it and the magnetic field that forms as the permanent magnet 7 on the secondary horse head 5 or 8 of linear electric motors was to this horse head 5 or 8 generation power, and made its motion, finished preceding one-half stroke thereby drive oil pumper; When oil pumper arrival work dead point, the sensor 3 at polished rod load place will be gathered the force signal that is subjected to that comes and issue control system 10, control system 10 provides the signal of electric current commutation, produce an opposing magnetic field between then elementary and secondary, at this moment opposite as secondary horse head 5 or 8 suffered power with the former, thus the back one-half stroke of oil pumper finished.
When needs braked, flat thin magnet 161 energising backs formed a magnetic field, and brake block 163 is pushed to as secondary horse head 5 or 8 side plates, and the frictional force of Xing Chenging makes this horse head 5 or 8 stop motions therebetween, realizes brake.When flat thin magnet 161 outage, brake block 163 retracts by flat thin magnet 161, and brake block 163 and this horse head 5 or 8 side plates are from, realization operate as normal.
