Power assembly 18 contains motor 40, reel 36, brake 23 and controller; Reel 36 suits are fixed on main shaft 31 middle parts; Main shaft 31 is installed on the bracket assembly 7 through two bearings and bearing support 32, and the one of which end is equipped with big belt pulley 37, and the other end is equipped with braked wheel 33; Big belt pulley 37 is connected with small belt pulley on being installed in motor 40 output shafts through belt 39; Motor 40 is installed on the bracket assembly 7, and braked wheel 33 matches with brake 34, and motor 40 is connected (not drawing among the figure) with controller.
Be provided with cannelure in the middle of reel 36 outer round surface; Be respectively arranged with the screw-type steel wire rope groove on reel 36 external surfaces of this cannelure the right and left, and reel 36 external surfaces on this cannelure left side are provided with left hand thread formula steel wire rope groove; Reel 36 external surfaces on its right are provided with right-handed thread formula steel wire rope groove; Wire rope 2 is eight, each four of front and back, and two and be one group.One end of eight wire rope is separately fixed on the reel 36, and is wrapped in respectively in the both sides steel wire rope groove of reel 36, and the other end of eight wire rope 2 is connected with the extrados of preceding horse head 6 and the extrados of back horse head 12 respectively.
As required, motor 40 adopts switched reluctance machines, and brake adopts liquid braking device; Steel wire rope groove is the bifilar helix groove; Controller adopts the PLC programmable logic controller, and the oil pumping of accurately controlling oil pumper is dynamic, and this controller also is provided with wireless remote sensing system; Can realize Long-distance Control, the hand-held programmer gets final product the duty of remote wireless control oil pumper.
Preceding horse head 6 is to equate that fully their center of arc is at same center with back horse head 12, and their center is axis of centres bearing 11 centers just; They were around 11 motions of the axis of centres bearing when motion was.Power assembly 18 drives haulage cable 2 actions when coming and going running, because of wire rope 2 connects with horse head, thereby also just driven horse head and start working.When motor 40 was just changeing, haulage cable 2 drove back horse head 12 and falls, and horse head 6 drive down-hole load rise before making; When motor 40 counter-rotatings, horse head 6 fell before haulage cable 2 drove, and made back horse head 12 drive counterweight and rose; Oil pumper has been accomplished the process of whole oil pumping.Strainer 20 has played the effect of tensioning haulage cable 2, and buffer gear assembly 19 has played the instant reversing impact that buffer rope produces when switching-over.
Switched reluctance machines has further increased output torque after output torque slows down through belt once more; Through being transferred on the reel 36 of main shaft 31.Reel 36 is as shown in Figure 7, and it is P for pitch, and helical pitch is L, and left end is left-handed, and right-hand member is the screw steel wire grooving of dextrorotation.Wire rope 2 is fixed on the reel 36, and twines on the reel 36 along thread groove.Wire rope 2 twines reel 36 along thread groove during work, and when the A end twined cylinder, the B end withdrawed from from cylinder gradually; Opposite action is arranged with it when returning stroke.The moment of torsion that acts on reel becomes following relationship with the wire rope power output:
F＝2k/D
F reel power output
K acts on the moment of torsion on the cylinder
The D drum diameter
This moment, reel 36 power outputs were shown in above-mentioned formula.For example act on the moment of torsion 3000Nm of reel 36, barrel dliameter is 400mm, and then reel 36 power outputs are 15000N.It is thus clear that this moment, power output was big, be feasible as driving directly therefore with motor 40.Fix and twined wire rope 2 on the reel 36, wire rope 2 drops the oil pumper running.Wire rope 2 has directly connected the extrados of preceding horse head 6 and back horse head 12; This wire rope 2 turns round along the horse head extrados; On the tangent line of horse head cambered surface, the stressed arm of force equates that this is normal relatively another energy-conservation main factor of beam pumping unit to the origin of force of wire rope 2 forever.Liquid braking device is to be used for complete machine braking use, and pumping-unit motor outage back Braking mode.
Change power assembly concrete structure, change the strainer assembly concrete structure, change the concrete structure of buffer gear assembly, and the concrete structure that changes horse head can form a plurality of embodiment, is common variation of the present invention, do not detail one by one at this.
