The single Horse Beam Pumping Unit that is provided with chain traction mechanism of the present utility model, comprise base, support, walking beam, beam hanger fixture, counterweight horse head and order about the power set that walking beam completes the oil pumping action, support is fixed on base, walking beam is stipulated and the top of support by back shaft, on the beam hanger fixture, is provided with sucker rod; Its special feature is: chain traction mechanism comprises drive motors, bottom gears and upper gear, and bottom gears is connected by chain drive with upper gear, and drive motors can order about undergear and rotate; The top of described support is fixed with left socle and right support, is fixed with top pulleys, middle part pulley on left socle, right support, and the bottom of support is fixed with bottom pulley; Be fixed with left pull rope and right pull rope on described chain, right pull rope is connected with sucker rod with after top pulleys on right support through the middle part pulley, and left pull rope fixes with the counterweight horse head after the top pulleys on bottom pulley, middle part pulley and left socle.
Support and base fix, and base is fixed on ground, to realize the fixing and supporting role to whole oil pumper.Walking beam is the top due to support by the back shaft degree, and the meeting section weight of bearing on walking beam and walking beam like this can be transmitted by back shaft, has so just shortened the application life of back shaft.Drive motors is rotated around bottom gears and upper gear for ordering about chain, in the process of chain movement, can to counterweight horse head, sucker rod, be drawn respectively by left pull rope, right pull rope, left socle and right support due to fixed top pulley, middle part pulley is fixed on support again, so effectively reduced the stressed of back shaft, walking beam, effectively extend the application life of back shaft, walking beam, reduced cost of production.
The single Horse Beam Pumping Unit that is provided with chain traction mechanism of the present utility model, be provided with connecting axle on described chain, left pull rope and right pull rope fix by connecting axle and chain; When the beam hanger fixture, during in minimum point, described connecting axle is at the highest notch on chain; When the beam hanger fixture is at the highest notch, connecting axle on chain in minimum point.
The single Horse Beam Pumping Unit that is provided with chain traction mechanism of the present utility model, described beam hanger fixture is connected with the auxiliary traction rope of right support upper top pulley by left socle with counterweight horse head warp.Like this, the counterweight horse head just can be drawn the beam hanger fixture by the auxiliary traction rope, has effectively reduced the stressed of walking beam.
The single Horse Beam Pumping Unit that is provided with chain traction mechanism of the present utility model, the top of described support is provided with gripper shoe, and left socle and right support all are fixed on gripper shoe.
The single Horse Beam Pumping Unit that is provided with chain traction mechanism of the present utility model, described left socle is connected by the connecting cross beam that plays reinforcement effect with right support.
The single Horse Beam Pumping Unit that is provided with chain traction mechanism of the present utility model, an end of described counterweight horse head is fixed with movable weight by pull rope.
The beneficial effects of the utility model are: of the present utility model pair of Horse Beam Pumping Unit, by the top at support fixedly left socle and right support, left pull rope, right pull rope are drawn counterweight horse head, sucker rod by the pulley on left socle, right support respectively, effectively reduced the stressed of back shaft, walking beam, extend the application life of back shaft, walking beam, reduced cost of production.By chain being arranged on bottom gears, upper gear, left pull rope, right pull rope fix by connecting axle and chain, make chain in the process of cycle rotation, can, periodically to the alternately traction of sucker rod, counterweight horse head, guarantee the automatic oil pumping of oil pumper.Of the present utility model pair of Horse Beam Pumping Unit only need carry out less change and can realize on existing Double head oil pumping, have change little, cost is low, the significant advantage of energy-saving effect.
The accompanying drawing explanation
Fig. 1 is the structural representation of existing two Horse Beam Pumping Units;
Fig. 2 is the structural representation that is provided with single Horse Beam Pumping Unit of chain traction mechanism of the present utility model;
The structure for amplifying schematic diagram that Fig. 3 is regional area in Fig. 2.
In figure: 1 base, 2 supports, 3 walking beams, 4 beam hanger fixtures, 5 sucker rods, 6 gripper shoes, 7 back shafts, 8 counterweight horse heads, 9 movable weights, 10 drive motors, 11 bottom gears, 12 chains, 13 connecting axles, 14 upper gear, 15 bottom pulley, 16 middle part pulleys, 17 top pulleys, 18 left socles, 19 right supports, 20 connecting cross beams, 21 left pull ropes, 22 right pull ropes, 23 auxiliary traction ropes.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, provided the structural representation of existing two Horse Beam Pumping Units, it comprises base 1, support 2, walking beam 3, beam hanger fixture 4, counterweight horse head 8 and orders about the power set (this part does not provide in the drawings) that it completes the oil pumping action, support 2 fixes with base 1, and walking beam 3 fixes by back shaft 7 and support 2.Like this, the active force that walking beam 3, beam hanger fixture 4, counterweight horse head 8 connection power set apply all can act on back shaft 7, and the active force that walking beam 3 bears is also larger, makes the application life of back shaft 7, walking beam 3 all shorter.
As shown in Figure 2, provided the structural representation that is provided with single Horse Beam Pumping Unit of chain traction mechanism of the present utility model, it,, except having with structure identical in Fig. 1, also comprises drive motors 10, bottom gears 11, chain 12, upper gear 14, bottom pulley 15, left socle 18, right support 19, connecting cross beam 20, left pull rope 21, right pull rope 22 and auxiliary traction rope 23; The top of support 2 is fixed with gripper shoe 6, and left socle 18 and right support 19 all are fixed on gripper shoe 6.All be fixed with top pulleys 17, middle part pulley 16 on left socle 18, right support 19, connecting cross beam 20 is for connecting left socle 18 and left socle 19, in order to increase its fastness.
In the process of installing, should guarantee that beam hanger fixture 4 is when minimum point, connecting axle 13 is at the highest notch on chain 12; When beam hanger fixture 4 is at the highest notch, connecting axle 13 on chain 12 in minimum point.Like this, in oil pumping process, right pull rope 22 moves traction to sucker rod 5 all the time; In the process of transferring at sucker rod 5, left pull rope 21, in the traction state to counterweight horse head 8, is convenient to transferring fast of sucker rod 5.Because the active force of left pull rope 21, right pull rope 22 acts on support 2 by left socle 18, right support 19, effectively alleviated the active force of walking beam 3, back shaft 7, increased its application life.
Structure for amplifying schematic diagram below in conjunction with the regional area of Fig. 2 and Fig. 3 describes the course of work that is provided with single Horse Beam Pumping Unit of chain traction mechanism of the present utility model:
When beam hanger fixture 4, during in minimum point, now connecting axle 13 is at the highest notch; Walking beam 3 will be rotated counterclockwise under the ordering about of power set, and chain 12 is also rotated counterclockwise under the drive of drive motors 10 simultaneously, and then moves upward by right pull rope 22 drive sucker rods 5; Now counterweight horse head 8 is also drawn by 23 pairs of beam hanger fixtures 4 of auxiliary traction rope.While having pumped, now beam hanger fixture 4 rises to peak, and connecting axle 13 drops to minimum point.Afterwards, connecting axle 13 under the drive of drive motors 10, can be from bottom to top motion, now connecting axle 13 can be by 21 pairs of counterweight horse heads 8 of left pull rope pulling force of exerting pressure, so that sucker rod 5 is transferred smoothly.
