Abstract
A wheel type oil pumping unit comprises a supporting frame, a base, an oil pumping rod, a rod pulling rope, a counterweight, a counterweight pulling rope, a drive wheel, a drive wheel frame, a power device and an electric control device. The wheel type oil pumping unit is characterized in that: the top of the supporting frame is provided with a head sheave, the bottom of the supporting frame is arranged at the base which is connected with the drive wheel frame by a hinge axis, the drive wheel is arranged at the drive wheel frame, the oil pumping rod is connected with one side of the head sheave circumference, the counterweight is connected with the other side of the head sheave circumference, the middle part of the drive rope is fixed at the drive wheel, and the two ends of the drive rope wind around the drive wheel in opposite direction and are respectively connected with the two sides of the head sheave circumference. The electric motor of the invention replaces the four-linkage direction changing mechanism of a beam type oil pumping unit in a way of forward-backward direction changing according to the procedure under the control of the electric control device, and the oil pumping rod and the counterweight are respectively hung at the two sides of the head sheave to realize static balance, therefore, the balance quality of the unit is high, the direction changing efficiency is high, the impact of direction changing is small, and stroke length and frequency are easy to be regulated.
Description
Technical field
The present invention relates to extracting device of oil, especially relate to a kind of wheel type oil pumping unit.
Background technology
Present oil field beam pumping unit such as CYJ type oil pumper commonly used, the complete mechanical switching mechanism of its commutation by quadric chain, the efficient that commutates is low, reversing impact big, transfer the stroke difficulty, and balancing is also difficult.
Summary of the invention
Technical problem to be solved by this invention provides a kind of motor under the control of electric control gear, the four connecting rod changements that replace beam pumping unit according to the mode of the positive and negative commutation of program, and the mode that sucker rod and counterweight are hung in the head sheave both sides realizes static balancing, so this machine balance quality height, commutation efficient height, reversing impact is little, transfers stroke, jig frequency easy.
For solving the problems of the technologies described above, the invention provides a kind of wheel type oil pumping unit, comprise bearing support, base, sucker rod, the beam hanger pull rope, counterweight, the counterweight pull rope, driving wheel, drive wheel carrier, power set, electric control gear, it is characterized in that: the bearing support top is equipped with head sheave, the bearing support bottom is installed on the base, connect the driving wheel carrier by hinge axis on the base, driving wheel is installed in and drives on the wheel carrier, sucker rod is connected to a side in head sheave wheel week, counterweight is connected to the opposite side in head sheave wheel week, drive the rope center fixed on driving wheel, drive the both sides that the rope two ends are wound in driving wheel in the opposite direction and are connected to head sheave wheel week separately.
Motor of the present invention is under the control of electric control gear, the four connecting rod changements that replace beam pumping unit according to the mode of the positive and negative commutation of program, and the mode that sucker rod and counterweight are hung in the head sheave both sides realizes static balancing, so this machine balance quality height, commutation efficient height, reversing impact is little, transfers stroke, jig frequency easy.
Description of drawings:
Fig. 1 is the structural representation of first embodiment of the invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is a second embodiment of the present invention structural representation;
Fig. 4 is the left view of Fig. 3.
The specific embodiment
With reference to Fig. 1, Fig. 2, the present invention includes base 1, hinge axis 2, drive wheel carrier 3, brake 4, small belt pulley 5, motor 6, sucker rod 7, polished rod eye 8, belt 9, beam hanger pull rope 10, drive rope 11, bearing support 12, it wheel shaft 13, little counterweight 14, head sheave 15, locator 16, counterweight pull rope 17, counterweight 18, driving wheel 19, big belt pulley 20, live axle 21, electrical control cubicles 22, encoder 23, head sheave 15 is installed on the bearing support 12 by sky wheel shaft 13, bearing support 12 is installed in again on the base 1, driving wheel 19 is installed in by live axle 21 and drives on the wheel carrier 3, driving wheel carrier 3 is installed on the base 1 by hinge axis 2, sucker rod 7 is linked the side that head sheave 15 is taken turns week by polished rod eye 8 and beam hanger pull rope 10, and counterweight 18 is connected to the opposite side that head sheave 15 is taken turns week by counterweight pull rope 17, the center fixed that drives rope 11 is on driving wheel 19, and take turns on the both sides in week according to linking head sheave 15 behind several circles of rightabout winding driving wheel respectively at the two ends of driving rope 11.When the driving rope was belt, then the belt two ends were connected in respectively on the both sides in head sheave wheel week, drive belt transmission with driving wheel then.
Power set comprise that motor 6, small belt pulley 5, big belt pulley 20, belt 9, motor 6 are installed on the driving wheel carrier 3, small belt pulley 5 is installed on the motor output shaft, big belt pulley 20 is installed on the live axle 21, and belt 9 connects small belt pulley 5 and big belt pulley 20.
Electric control gear adopts the form of electrical control cubicles 22, and it links to each other with encoder 23 and locator 16 with motor 6.
Because driving wheel carrier 3 is connected on the base 1 by hinge axis 2, therefore regulate the tensile force that drives rope 11 by the weight size at driving wheel 19 positions, it is simple in structure, reliable, and regulates tensile force by the machine own wt, works the reversing impact effect of eliminating complete machine simultaneously.
Generally speaking, this machine simplified widely complex machines structure, greatly reduce the machine manufacturing cost, and manufacturing process is also simple, bring simultaneously energy-conservation greatly, save the effect of steel greatly, and it is easy to regulate every technical data, use simple, convenient, with the remote controller adjusting, therefore safe especially fully.
With reference to Fig. 3, Fig. 4, embodiment 2 is with embodiment 1 difference: counterweight 18 is fixed on the head sheave 15 by rocking arm among the embodiment 2, does not therefore have counterweight pull rope 17 and little counterweight 14, and other and embodiment 1 are identical.
