Abstract
A six-connecting-bar oscillating beam-pumping machine employed in the oil field comprises a crank 3, a lower connecting bar 4, a rack 5, a swing bar 6, a tail-end balancing-weight of the swing bar 10, an upper connecting bar 11 and a balancing weight at upper and back of the swing bar. The rotating center of the swing bar 6 is fixed on the rack 5 and connected with the upper connecting bar 11 and the lower connecting bar 4 respectively. The connection between the upper connecting bar and the swing bar has three different positions to adjust the stroke, and the stretching forces of the upper connecting bar and the lower connecting bar can be reduced through the adjusting the weight and position of different balancing-weight blocks on the two components, besides, the output torque of the decelerator and the power of the motor are reduced thereby saving the energy up to 30% to 40%.
Description
Technical field: the utility model relates to a kind of oil field with six connecting rod swing-rod pumping unit.
Background technology: conventional beam-pumping unit adopts the quadric chain design, the motor driving reducer rotation, by crank, connecting rod and walking beam, horse head becomes sucker rod and pumps, realize by three diverse locations on crank by adjustment connecting rod and crank-pin for three strokes of complete machine, and assembled machine balance realizes that by adjusting crank balance hammer position common beam oil pump speed reducer output shaft torque is relatively large, electrode power is also bigger, so consumed power is many.
Goal of the invention: the purpose of this utility model is to provide a kind of single raise fork and fork counterweight of increasing, and reducer output shaft moment of torsion and motor power (output) are reduced, thus the six connecting rod swing-rod pumping unit that can save 30～40% electric energy.
Summary of the invention: the utility model is gone up counterweight 12 after being achieved in that and comprising base 1, reducer 2, crank 3, lower link 4, support 5, fork 6, horse head 7, walking beam 8, crossbeam 9, fork tail balancing weight 10, last connecting rod 11, fork, support 5, reducer 2 are arranged on the base 1, crank 3 is installed on reducer 2 output shafts and with lower link 4 and is connected, support 5 is connected with walking beam 8, there is horse head 7 end of walking beam 8, last connecting rod 11 is connected with walking beam 8 by crossbeam 9, the centre of gyration of fork 6 is fixed on the support 5, and is connected with last connecting rod 11, lower link 4 respectively.
The utility model also adopts following technical scheme:
Last connecting rod 11 can have three with the tie point of fork 6.
On the crank 3 pin shaft hole is arranged.
Advantage of the present utility model is: three the different positions that are connected with of going up connecting rod and fork, the corresponding stroke in each position, the stroke that promptly adjusts is used, because fork afterbody and fork upper back install balancing weight respectively additional, be used for balance horse head polished rod load, also install balance weight additional on the crank simultaneously, weight and position by the different balancing weights on two parts of suitable adjustment, the suffered pulling force of connecting rod and lower link is all reduced, because the crank pin radius of gyration is a definite value, corresponding the reducing of clean moment of torsion that reducer output shaft is suffered, the also corresponding minimizing of peak torque peak value, therefore employed reducer output shaft moment of torsion is compared with the same model conventional beam-pumping unit all with power of motor and is reduced, but energy conservation 30～40%.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Specific embodiments: the utility model is further described below in conjunction with accompanying drawing:
The utility model is mainly by base 1, reducer 2, crank 3, lower link 4, support 5, fork 6, horse head 7, walking beam 8, crossbeam 9, fork tail balancing weight 10, last connecting rod 11, going up counterweight 12 behind the fork forms, its horse head 7, walking beam 8, crossbeam 9 is identical with the parts of conventional beam-pumping unit with the coupling head of connecting rod two ends, its inventive point is to increase a fork 6, the center of rotation of fork 6 is fixed on the support 5, the oscillation center of walking beam 8 is fixed on the top of support 5, be up and down laterally installation with fork 6, one end of walking beam 8 and horse head 7 are installed, the other end is connected the back and is connected through the hinge with fork 6 by last connecting rod 11 with crossbeam 9, lower link 4 is connected through the hinge with crank 3 and fork 6, crank 3 is installed on the output shaft of reducer 2, three the different positions that are connected with of last connecting rod 11 and fork 6, the corresponding stroke in each position, has only a pin shaft hole position on the crank, fork 6 afterbodys are equipped with the fork tail balancing weight 10 of adjustable weight respectively, go up counterweight 12 behind the fork, use to adjust balance.
This device can be used for the technological transformation of same model conventional beam-pumping unit.
