(5) specific embodiment:
Consult Fig. 1, be embedded with concrete pedestal (2) on the earth (1), on it oil pumper support (3), support (4) is housed above the support, support shaft (5) is equipped with at the top of support, and walking beam (6) and horse head (7) can be around the swings of this support shaft, is polished rod eye (8) below the horse head, this polished rod eye is hanging load, only moves up and down not participate in swing.Switchbox (16), brake gear (15), dragging motor (17) are equipped with in the rear portion of oil pumper, belt (18) couples together motor and belt pulley (19), reduction box (9) also is equipped with at the support rear portion, reduction gearbox output shaft (11) is housed on it, crank (10) is housed on the output shaft, the other end of crank is connected with connecting rod (13) by a crank-pin (12), and the other end of connecting rod is connected with the tailing axle (14) of walking beam rear lower.The afterbody of walking beam is equipped with lengthening beam (20), and suspended axle (21) is housed on it, and it is hanging pendulum bell (23) by balance arm (22), and the pendulum bell is made up of the several oscillating disc, is fixed together by pendulum bell axle (24) and fixed screw (25) series connection.Stressed backplate (28) is housed in the inboard of balance arm, and its push pedal (27) below lengthening beam is corresponding, and the damping rubber cushion is equipped with in the push pedal outside, and push pedal can move forward and backward under the promotion of leading screw (26).Screw-threaded shaft elevator (32) is fixed on the walking beam (6) by screw-threaded shaft elevator fixture (33), and can be according to the balance needs, fixing position is moved in front and back, the end of leading screw (30) is connected with walking beam auxiliary balance heavy (29), can move forward and backward under the drive of control motor (31), the walking beam auxiliary balance is heavy also can be according to balance needs increase and decrease quality.
Current sensor (35) is installed on the dragging motor lead, and pass through holding wire (36) and give single-chip microcomputer (34), position sensor (37) symmetry is installed in a certain position on the reduction box (9), and pass to single-chip microcomputer (34) by holding wire (38), the control signal that single-chip microcomputer sends is connected with control motor (31) on the walking beam by control motor lead (39).
Horse head moves downward this process of walking beam horizontal level from top dead-centre, and pendulum bell (23) is sagging always, and it has done a rotation with respect to suspended axle (21), has done an approximate rectilinear motion upwards with respect to ground.Horse head moves to this process of bottom dead centre from horizontal level, the pendulum bell begins to do circular motion around support shaft (5) together with walking beam under the promotion of push pedal (27), because this circular arc has been crossed over horizontal diameter just, therefore also done an approximate rectilinear motion upwards.Like this, the whole motion process of horse head from the top dead-centre to the bottom dead centre, the pendulum bell has been done two approximate rectilinear motions up and down continuously, and changes very little with respect to the trimming moment of support shaft.As required, adjust the front and back position of leading screw (26), can change the position of the initial rotation point of pendulum bell, and then can roughly change upward bottom dead centre equilibrant force magnitude proportion, adapting to the needs of the inertia force that high frequency motion produced, initial rotation point in advance, it is big that the equilibrant force of lower dead point position becomes.
When reasons such as oil well liquid level fluctuation cause the horse head load to change, will cause the oil pumper off-center operation, the peak point current ratio of motor and up and down the time scale of stroke generally all can change, adjust the front and back position of the auxiliary balance heavy (29) on the walking beam in good time, just can readjust balance, to adapt to this variation needs.On the one hand, current sensor (35) can be passed to single-chip microcomputer to unbalanced load current signal, single-chip microcomputer can send instruction by controlling motor lead (39) and allow control motor (31) on the screw-threaded shaft elevator just change or reversing, promoting the walking beam auxiliary balance heavily moves forward and backward, when the ascending current peak value greater than the centrifugal current peak value and when reaching certain proportion, explanation is a underbalance, auxiliary balance heavily is moved to the left, increase equilibrant force, otherwise, when the ascending current peak value less than the centrifugal current peak value and when reaching certain proportion, explanation is overbalance, the walking beam auxiliary balance heavily moves right, and reduces equilibrant force.On the other hand, two position sensors (37) that symmetry is installed can be passed to single-chip microcomputer to the unbalanced time scale signal of stroke up and down, single-chip microcomputer can send instruction by controlling motor lead (39) and allow control motor (31) on the screw-threaded shaft elevator just change or reversing, promoting the walking beam auxiliary balance heavily moves forward and backward, when last line time greater than downgoing time and when reaching certain proportion, explanation is a underbalance, the walking beam auxiliary balance heavily is moved to the left, increase equilibrant force, otherwise, when last line time less than downgoing time and when reaching certain proportion, explanation is overbalance, the walking beam auxiliary balance heavily moves right, and reduces equilibrant force.
Consult Fig. 2, from this figure as can be seen horse head at the location status of top dead-centre time pendulum bell.
Consult Fig. 3, from this figure as can be seen horse head at the location status of bottom dead centre time pendulum bell.
