Abstract
The utility model relates to a direct balance pumping unit of walking beams of single cranks, which is mainly composed of a motor (1), a belt transmission (2), a reducer (3), a crank (4), a connecting rod (5), a walking beam (6), a bracket (8), a cambered surface (9), a brake (10), a balancer (13), a piece of lifting rope (14) and a pumping rod (15); wherein, the output shaft of the reducer (3) protrudes only from one side of the shell body of the reducer, the protruding end is provided with the crank, the connecting rod (5) is used for articulating the crank (4) and the walking beam (6), the balancer (13) is arranged on the inclining beam on the tail of the walking beam (6), therefore can realize direct balance of the walking beam with good balancing effect and low energy consumption. Having only one connecting rod (5) remained in the transmission pieces makes the pimping device more simple and the single crank transmission has no scissors difference, therefore greatly simplifies the manufacturing technics of the pumping machine and decreases the manufacturing cost of the pumping machine.
Description
One, technical field
The direct balanced oil extractor of single crank walking beam that the utility model relates to belongs to a kind of ground installation that petroleum industry machinery oil production is used.
Two, background technology
Oil pumper is one of capital equipment of using of suction crude oil, and what our times various countries ground machine oil production equipment commonly used adopted more than 80 percent is the walking beam machine oil pumper (Fig. 3) of crank balance.Though the beam-pumping unit of crank balance is simple, solid, reliable, counterbalance effect is bad, the energy consumption height.Particularly this oil pumper must adopt double-crank, when making two crank run-in synchronism errors too big owing to the manufacturing reason, oil pumper can't operate as normal, and therefore, People's Republic of China's petroleum industry standard (SY/T5044-2003) does to this error that there are strict requirements.
Three, summary of the invention
The purpose of this utility model provides the direct balanced oil extractor of a kind of single crank walking beam.This machine can not only make oil pumper realize the balance of balance-type type, improve the counterbalance effect of oil pumper greatly, reduce the oil pumper peak torque, cut down the consumption of energy, and has only a crank, there is not two cranks nonsynchronous problem that turns round, reduced the difficulty of processing of oil pumper, the only surplus connecting rod of driving member makes the structure of oil pumper become simpler, solid, reliable.
The purpose of this utility model realizes by following scheme, afterbody at the walking beam of crank balanced pumping unit is made a downward inclined beams, with the balance weight that was added in originally on the crank, move on on the inclined beams of walking beam afterbody after changing shape, thereby the beam-pumping unit of crank balance has been transformed into the direct balanced oil extractor of walking beam.The crank balance beam-pumping unit adopts the main cause of double-crank, be because crank is contained on the output shaft of reducer, very heavy balance weight is housed on the crank, if only crank in reducer shell one side, oil pumper will be laid particular stress on because of reducer can't operate as normal.Because beam-balanced pumping unit does not have balance weight, thereby just can adorn a crank in reducer one side on the crank, with a connecting rod that crank and walking beam is hinged, thereby constitute the direct balanced oil extractor of single crank walking beam.This machine is by motor, the band transmission, reducer, brake, crank, connecting rod, walking beam, cambered surface (horse head), lifting rope, equalizer and sucker rod are formed, motor is after band transmission and reducer deceleration, driving crank at the uniform velocity rotates, crank drives walking beam through connecting rod and swings repeatedly, sucker rod is wrapped on the cambered surface with lifting rope, when swinging up and down, walking beam will drive sucker rod and equalizer rises repeatedly and descends, sucker rod back and forth rises and descends and reaches the purpose of aspirating crude oil from oil well, equalizer be used to the to offset load of sucker rod, reduce the moment of torsion of crank axle, brake is used for guaranteeing that walking beam is parked in the optional position when repairing oil pumper.
Four, description of drawings
Fig. 1 is the drive mechanism schematic diagram of the direct balanced oil extractor of single crank walking beam.
Fig. 2 is supporting bar structure figure.
Fig. 3 is the crank balanced pumping unit structure chart.
Five, the specific embodiment
Further describe utility model embodiment below with reference to the accompanying drawings:
Referring to Fig. 1, the direct balanced oil extractor of a kind of single crank walking beam, by motor (1), band transmission (2), reducer (3), crank (4), connecting rod (5), walking beam (6), inspection platform (7), support (8), cambered surface (9), brake (10), erosion control device (11) and (12), equalizer (13), lifting rope (14), support bar (16) and sucker rod (15) are formed, the output shaft of reducer (3) only stretches out from a side of reducer (3) housing, at external part a crank (4) is housed, hinged with a connecting rod (5) crank (4) and walking beam (6), motor (1) and reducer (3) are installed on the base of support (8) bottom, (6 are installed in the top of support (8) to walking beam, same support (8) adopts hinge to connect, the front end of walking beam is equipped with a cambered surface (9), sucker rod (15) is suspended on the cambered surface (9) with lifting rope (14), the rear end of walking beam (6) is downward-sloping, at its afterbody equalizer (13) is housed.When motor (1) rotates, will swing up and down by band transmission (2), reducer (3), crank (4), connecting rod (5), drive walking beam (6).Walking beam (6) is when swinging up and down, to drive sucker rod (15) and back and forth rise and descend and reach from oil well the purpose of suction crude oil, equalizer (13) be used to the to offset load of sucker rod reduces the moment of torsion of crank axle, brake (10) is used for guaranteeing that walking beam is parked in the optional position when the maintenance oil pumper.
In the present embodiment; solve connecting rod (5) fracture suddenly; prevent that the purpose that equalizer (13) or cambered surface (9) fall to smashing main equipment from implementing by Fig. 1; among Fig. 1; erosion control device (11) and (12) have been installed on support (8); erosion control device (11) and (12) are made by elastomeric material, can absorb the energy that impact produces, and equipment itself is protected.
In the present embodiment, when transferring stroke or maintenance, prevent that folding from falling the purpose of connecting rod (5) back walking beam (6) whereabouts by Fig. 1 and Fig. 2 enforcement, between walking beam (6) and support (8), a support bar (16) has been installed among Fig. 1, support bar (16) is made up of body (16a) and nipple (16b), rotate nipple (16b) strut (16) is elongated or shortened, walking beam (6) is locked in desired location with convenient.
The direct balanced oil extractor of single crank walking beam of the present utility model, it is improvement to the crank balance beam-pumping unit, only surplus connecting rod (5) of driving member and the hinge that is connected walking beam (6) and support (8), thereby make oil pumper become simpler, solid, reliably, but also can realize the direct balance of walking beam, it is poor to have overcome the crank balanced pumping unit counterbalance effect, the shortcoming that peak torque is big, increased the hoisting power of oil pumper, reduced power consumption, reduced cost for oil production, there is not two cranks nonsynchronous problem that turns round in the single crank transmission, solved the trouble of two crank price scissors of necessary strict control in the oil pumper manufacturing, make the processing technology of oil pumper become simpler, processing cost is lower.
