Abstract
The utility model relates to an improvement of a pumping unit used for an oil field, in particular to an improved energy saving pumping unit, comprising a suspension cable of a pumping rod, a mule head, a walking beam bracket, a walking beam, an electric machine, a connecting rod, a secondary reduction large belt pulley, a secondary reduction small belt pulley, a belt pulley of the electric machine, a main driving belt, an ancillary drive belt, a main reduction belt pulley of a crank arm and a balance arm arranged fixedly in radial distribution and a balance weight arranged on the balance arm; wherein the main reduction belt pulley and the secondary reduction small belt pulley are a chain wheel; the main driving belt is a driving chain. The secondary reduction large belt pulley and the belt pulley of the electric machine are a tooth shaped belt pulley; the ancillary drive belt is a tooth shaped driving belt. The utility model has the advantages of simple structure, high transmission efficiency, large transmitted driving force and non-easy slippage, thereby being suitable for a large-scale pumping well needing a great driving force.
Description
Technical field: the utility model relates to the improvement of a kind of oil field with oil pumping machinery, is meant a kind of improved energy-saving pumping unit especially.
Background technology: oil pumper is the ground oil production equipment that is used for being not enough to from formation pressure the oil well extraction crude oil of blowing, the high energy consumption of oil pumper, complex structure and maintenance difficulty are the main causes that causes its use cost high always, people have designed the low and new-type energy-saving pumping unit simple in structure of a lot of energy consumptions for this reason, as being 02206942.9 on January 29th, 2002 to the number of patent application that Patent Office of the People's Republic of China proposes by the utility model patent applicant, it is exactly wherein a kind of that name is called disclosed oil pumper in the Chinese utility application of " energy-saving pumping unit ", the shift drive mechanism that this energy-saving pumping unit is made up of driving belt and belt pulley with two-stage has replaced the requirement on machining accuracy height, the energy consumption height, easy oil leakage, the gearbox that maintenance cost and manufacturing cost are high, thereby reach purpose energy-conservation and the reduction manufacturing cost and use cost, and it has substituted common driving belt and belt pulley in order to prevent to skid between driving belt and the belt pulley and improve driving force with profile of tooth driving belt and toothed belt wheel, but since profile of tooth driving belt self intensity a little less than, it still is difficult to bear and transmit bigger driving force, needs the less middle-size and small-size pumpingh well of driving force to use so above-mentioned energy-saving pumping unit can only be applicable to.
The utility model content: the purpose of this utility model provides and a kind ofly can be applicable to the improved energy-saving pumping unit that need use than the large-scale pumpingh well of large driving force.
The purpose of this utility model is achieved in that a kind of improved energy-saving pumping unit, comprise sucker rod suspension cable, horse head, walking beam support, walking beam, motor, connecting rod, secondary deceleration big belt pulley, secondary deceleration small pulley, motor pulley, main transmission band, ancillary drive belt, be set with the main speed reducing pulley of radially-arranged crank arm and counter-jib on it and be arranged on counterweight on the counter-jib, wherein main speed reducing pulley and secondary deceleration small pulley are sprocket wheel, and the main transmission band is a driving chain.
Secondary deceleration big belt pulley and motor pulley are toothed belt wheel, and ancillary drive belt is the profile of tooth driving belt.
Because the secondary transmission mechanism of being made up of main speed reducing pulley, secondary deceleration small pulley and main transmission band in the utility model be for can transmitting the chain-drive mechanism than large driving force, thus its with form by profile of tooth driving belt and toothed belt wheel the secondary transmission mechanism compare have that transmission efficiency is higher, non-slip fully, single staged transmission ratio greatly, advantage that the load capacity scope is big; And since the utility model in by pair deceleration big belt pulley, the one-level transmission mechanism that motor pulley and ancillary drive belt constitute still adopt overload change the self preservation effect of can skidding when excessive by belt pulley, driving belt or toothed belt wheel, the transmission mechanism that the profile of tooth driving belt is formed, so the damage that in the time of can preventing effectively that by it oil pumper from running into the very big and rapid backward rotation operating mode of loads change at work each drive disk assembly and motor in the utility model is caused, promptly the utility model successfully will be known as the chain drive that should not adopt in the art and successfully be incorporated among the transmission system of oil pumper in the oil pumper transmission system.
Description of drawings: accompanying drawing is a structural representation of the present utility model
Among the figure: 1-sucker rod suspension cable 2-horse head 3-walking beam support
4-walking beam 5-connecting rod 6-crank arm
The secondary deceleration big belt pulley of 7-counterweight 8-counter-jib 9-
10-ancillary drive belt 11-motor 12-motor pulley
The secondary deceleration small pulley of 13-14-main transmission band 15-master speed reducing pulley
The specific embodiment: a kind of improved energy-saving pumping unit, comprise sucker rod suspension cable 1, horse head 2, walking beam support 3, walking beam 4, motor 11, connecting rod 5, secondary deceleration big belt pulley 9, secondary deceleration small pulley 13, motor pulley 12, main transmission band 14, ancillary drive belt 10, be set with the main speed reducing pulley 15 of radially-arranged crank arm 6 and counter-jib 8 on it and be arranged on counterweight 7 on the counter-jib 8, wherein main speed reducing pulley 15 and secondary deceleration small pulley 13 are sprocket wheel, and main transmission band 14 is a driving chain.
For easily skidding of overcoming further that common driving belt and belt pulley exist, single staged transmission ratio is little, the load capacity scope is little defective, secondary deceleration big belt pulley 9 and motor pulley 12 can also adopt toothed belt wheel, and ancillary drive belt 10 can adopt the profile of tooth driving belt; The above-mentioned one-level transmission mechanism that is made of profile of tooth driving belt and toothed belt wheel can improve single staged transmission ratio, transmit bigger driving force, and is difficult for skidding; But when load has greatly changed distortion strength above the profile of tooth driving belt; the profile of tooth driving belt has the response characteristic that skids again; so the existence of this one-level transmission mechanism has successfully solved the defective that chain drive should not be used in the very big and rapid reverse transmission of loads change, it can play the effect of each drive disk assembly and motor 11 in protection the utility model.
