Abstract
The utility model provides a sliding auxiliary balance device on conventional pumping unit curved beam, belonging to balance technical field of mechanical oil production conventional pumping unit in the oil exploitation. The end part of a beam is provided with a curved beam and is provided with an assembly pulley for supporting a set of counterweight which can slide and can be adjusted. A pair of swing rods is arranged on a cross beam and is hinged with the sliding counterweight. When the beam swings upwards and downwards to complete pumping crude oil in the whole process, the sliding counterweight slides in reciprocating mode under the pulling action of the swing rod so as to balance the varying load in upward and downward stroke of a suspension center and thus the purpose of decreasing ton liquid energy consumption is realized.
Description
Affiliated technical field
The utility model relates to the auxiliary balance device on a kind of oil pumper that mechanical oil recovery uses in oil exploitation, especially can be used for conventional beam-pumping unit is transformed into the purpose that camber beam slip auxiliary balance formula oil pumper reaches energy efficient.
Background technology
At present, known conventional beam-pumping unit carries out the motion of mechanism balance by the crank counterbalance in the rotation entirely when pumping operation, and this has just caused energy consumption excessive.Existing existing technology is that the afterbody at the walking beam of conventional beam-pumping unit installs (out-phase) counterweight additional, thereby reaches purpose of energy saving.But because the various operating mode of non-adjustable very difficult adaptation at the out-phase angle of this kind out-phase walking beam balancing weight, individual other operating mode also may cause bigger energy consumption.
Summary of the invention
In order to overcome the big defective of existing conventional beam pumping unit counterbalance effect difference energy consumption, the utility model provides a kind of conventional pumping unit camber beam slip auxiliary balance device, and it can realize balance and energy-conservation by slide balance.
The technical scheme that its technical problem that solves the utility model adopts is: increase a camber beam (8) at the afterbody of the walking beam (11) of conventional beam-pumping unit and 1 assembly pulley (7) is installed in the above and is being supported a cover slidably and adjustable balance weight (6), go up at crossbeam (10) and one pair of fork (9) is installed and is hinged with slide balance heavy (6).
When walking beam swings up and down when finishing overall process suction crude oil: slide balance focuses under the pulling function of fork and reciprocatingly slides on camber beam, thereby balance weight is changed in the load variations in the stroke up and down with the suspension point of walking beam front end horse head, effectively balance the load of change, it is energy-conservation to make the oil pumping function drive the rotation realization under less energy consumption.Make the net torque curve of reducer milder simultaneously, application life has been grown in the court of a feudal ruler.
The beneficial effects of the utility model are, the effective balance of slip by balance weight oil pumper polished rod load and can realize energy-conservation 20%, simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
1. motors among the figure, 2. belt, 3. reduction box, 4. crank, 5. connecting rod, 6. slide balance is heavy, 7. pulley, 8. camber beam, 9. fork, 10. crossbeam, 11. walking beams, 12. supports, 13. horse heads, 14. wire rope, 15. polished rod eyes, 16. bases.
The specific embodiment
In the drawings, use belt (2) transmission between motor (1) and the reduction box (3), and the driven axle of reduction box (3) links to each other with crank (4),. connecting rod (5) crossbeam (10) walking beam (11) support (12) interconnects with bearing with crank (4), horse head (13) is hinged with walking beam (11) front end, on the camber beam (8) that the afterbody of walking beam (11) installs additional 1 assembly pulley (7) is installed and is supporting a cover slidably and adjustable balance weight (6), fork (9) is installed in that crossbeam (10) is gone up and is hinged with slide balance heavy (6).
The utility model is earlier adjusted slide balance heavy (6) according to the load of production wellhead before use and is hung up well head with the polished rod eye (15) of wire rope (14) and load, then starter motor (1) rotates by belt (2) drive reduction box (3) and crank (4).And connecting rod (5) walking beam (11) horse head (13) produces swing up and down reciprocatingly with the rotation of crank (4), and fork (9) is swung and dragged slide balance heavy (6) with the swing of connecting rod (5) and moves reciprocatingly, and finishes the overall process of energy-conservation reciprocal reciprocating oil pumping.
Claims (3)
1. a conventional pumping unit camber beam is slided auxilliary bascule, it is that afterbody by the walking beam in the conventional beam-pumping unit structure (11) installs a camber beam (8) and additional and overlaps slidably balance weight (6), and be hinged with the one pair of fork (9) that is installed on the crossbeam (10), it is characterized in that: the walking beam afterbody installs a camber beam (8) and additional and overlaps slidably balance weight (6), and crossbeam (10) is gone up one pair of fork (9) is installed.
2. the sliding auxilliary bascule of conventional pumping unit camber beam according to claim 1 is characterized in that: the camber beam that the walking beam afterbody installs additional (8) is gone up installation 1 assembly pulley (7) and is being supported one and overlapping slidably and adjustable balance weight (6).
