Description
Technical field
The utility model relates to a kind of oil extraction machinery and equipment, a kind of more precisely planet autobalance beam pumping unit.
Background technique
At present, China oil field has reached more than 60,000 of row at the beam pumping unit of usefulness, its sum accounts for more than 90% of mechanical oil recovery sum, mainly contain two kinds of structures of conventional type and out-phase type, its shortcoming is that load is inhomogeneous in whole work cycle, concerning static load, during upstroke, the horse head suspension point need be mentioned sucker rod and oil column, at this moment motor will be exported very big energy, during to down stroke, sucker rod relies on deadweight just can fall, this moment, motor need not to export energy, on the contrary motor is done work, and the variation of point suspension movement speed and acceleration has aggravated this nonuniformity, the nonuniformity of cutting lotus has had a strong impact on quadratic crank mechanism, the working life of speed reducer and motor, also worsened the operating conditions of sucker rod, the rod broken number of times is significantly increased, to this prior art is to install and fix the formula balancer weight to solve on the crank of pumping unit, though this on certain Cheng Du balance the load of up-down stroke, but speed reducer crank torque when up-down stroke changes (as shown in Figure 2) still very greatly, thereby has increased energy consumption, has reduced the efficient of pumping unit.
The model utility content
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of planet autobalance beam pumping unit that reduces clean torque peak value of speed reducer crank and negative twist distance.This pumping unit is at conventional type pumping unit and out-phase type oil pumping machine crank balance shortcoming and the new pumping unit that designs.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of planet autobalance beam pumping unit, comprise motor, speed reducer, crank, connecting rod, crossbeam, horse head and sucker rod, motor drives crank by speed reducer and rotates, crossbeam is connected with crank by connecting rod, horse head and sucker rod are installed in the front end of crossbeam, by pinion stand fixed gear with the coaxial setting of crank is installed on the speed reducer, the planetary pinion and the balancer weight that are meshed with fixed gear are installed on the crank, be connected by the balancer weight connecting rod between planetary pinion and the balancer weight, offer orbital groove on the crank, the balancer weight wheel that can move in orbital groove is installed on the balancer weight.
Described orbital groove is offered the cranked left and right sides symmetrically, four balancer weight wheels is installed on the balancer weight is slidingly matched with it.
Described balancer weight connecting rod one end is connected by bearing pin with the planetary pinion outer edge, and the other end is connected by bearing pin with the balancer weight middle part.
Described crossbeam is connected at the middle part with crank by connecting rod.
Described planetary pinion and fixed gear equal diameters, crank rotates a circle, planetary pinion under the drive of crank around fixed gear from three-sixth turn.
Described balancer weight connecting rod is length-adjustable telescopic connecting rod.
The pinion stand of described fixed gear welds or is cast directly on the speed reducer.
Crank of the present utility model can drive planetary pinion and rotate around fixed gear in rotary course, and then it is reciprocating on crank to drive balancer weight by the balancer weight connecting rod, crank angle moment of torsion maximum in the time of 75 ° when upstroke, this moment, the distance of balancer weight and speed reducer was also maximum, the crank angle is in the time of 75 °-180 °, the speed reducer moment of torsion reduces gradually, distance between balancer weight and the reduction gearbox output shaft also reduces gradually simultaneously, the crank angle is in the time of 180 °-285 °, the down stroke moment of torsion increases gradually, the distance of balancer weight and reduction gearbox output shaft continues to reduce, the crank angle is in the time of 285 °-360 °, torque reduces gradually, the distance of balancer weight and reduction gearbox output shaft then increases gradually, thereby reaches good balance, energy-saving effect, speed reducer crank torque are with the change curve of crank angle as shown in Figure 2, wherein solid line is represented the pumping unit of lack of equilibrium, and dotted line is represented the pumping unit that balance is good.Utilize the utility model to transform used out-phase type in oil field and conventional type pumping unit, also can make brand-new pumping unit replaces old-fashioned pumping unit certainly, has very wide application prospect.
