The pumping unit is composed of a head sheave, a frame, a motor, a big gear, a small gear, a big pulley and a small pulley. One end of the flexible driving belt is linked with a sucker rod, and the other end is linked to the balance weight around the head sheave. The pumping unit is characterized in that: The head sheave is fixed on the top of the frame; the motor is fixed on the frame below the big pulley; between the motor and the head sheave, a speed reduction gearing made of the big gear, the small gear, the big pulley and the small pulley is disposed; the head sheave is fixed with the big gear co-axially; and the small gear and the big pulley are fixed on the same shaft which is fixed on the frame below the head sheave. The utility model has the advantages of simple complete machine manufacturing technology, low price and high efficiency.

Description

Head sheave type oil pumper with simple speed reduction gearing
Technical field
The utility model relates to a kind of head sheave type oil pumper with simple speed reduction gearing, belongs to the oil exploitation mechanical field.
Background technology
Oil pumper is a topmost plant equipment in the oil exploitation, and traditional beam pumping unit is owing to have a high reliability, so far dominate in oil exploitation still.But because its baroque shortcoming, cause efficient low, transfer ginseng inconvenience, significant discomfort is answered the development of oil recovery technique.For overcoming the shortcoming of beam pumping unit, the technical scheme that Chinese patent 00246414.4 provides a kind of " efficient; low consumption; intellectual oil pumper ", the technical scheme that Chinese patent 02104386.8 provides a kind of " low speed synchromotor oil pumper ", the technical scheme that Chinese patent 02288796.2 provides a kind of " direct-drive type head sheave oil pumper ", their common characteristic are: the mode that adopts the work of high-power low-speed motor direct-drive oil well pump, saved the transmission system of beam pumping unit complexity, overall structure is greatly simplified, improved system effectiveness, adopt the modern electrical machine control technology simultaneously, to turning to of motor, rotating speed is controlled, thus can be easily to the stroke of oil pumper, jig frequency is adjusted.But there is a common deficiency in technique scheme, that is: because no speed reduction gearing, thus must adopt the low speed heavy-duty motor directly to drive as power, however this low speed heavy-duty motor manufacturing process complexity not only, difficulty is big, and cost is very expensive.Hindered the enforcement of technique scheme just because of this shortcoming, after indivedual the enforcement, also greatly reduced the market competitiveness because of its complete machine cost is high.
Summary of the invention
Must adopt the deficiency of low speed heavy-duty motor as power in order to overcome technique scheme, the utility model provides a kind of oil pumper, and this oil pumper has simple speed reduction gearing, thereby can be with common electric machine as power.
The purpose of this utility model is achieved through the following technical solutions: a kind of head sheave type oil pumper with simple speed reduction gearing is made up of head sheave, frame, motor, gear wheel, pinion, big belt pulley, small belt pulley etc., flexible driving band one end links to each other with sucker rod, walk around head sheave, the other end links to each other with counterweight.It is characterized in that: at frame top, motor is fixed on the frame of big belt pulley below head sheave by bearing fixing, and motor is to having the speed reduction gearing that is made of gear wheel, pinion, big belt pulley, small belt pulley between the head sheave.
Described head sheave is characterized in that: head sheave and gear wheel are coaxial to be fixed together, and constitutes a compound integral body.
Described speed reduction gearing is characterized in that: pinion and big belt pulley are fixed on the same axle, and by bearing fixing on the frame below the head sheave.
The utility model has the advantages that: the complete machine manufacturing process is simple, and cost is low, the efficient height.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of speed reduction gearing of the present utility model.
Among the figure: 1. head sheave, 2. gear wheel, 3. bearing, 4. frame, 5. pinion, 6. big belt pulley, 7. bearing, 8. belt, 9. motor, 10. small belt pulley, 11. flexible driving bands, 12. sucker rods, 13. counterweights, 14. control cabinets.
The specific embodiment
Small belt pulley in the utility model, big belt pulley and head sheave can be each one, constitute the single armed transmission, also can be each two, constitute the both arms transmission.This specific embodiment adopts each two, constitutes the both arms transmission.Below in conjunction with specific embodiment the utility model is described further.
Have the head sheave type oil pumper of simple speed reduction gearing, Fig. 1 can be used as the structural representation of this specific embodiment, and Fig. 2 can be used as the structural representation of the speed reduction gearing of this specific embodiment.Pinion (5) is meshed with gear wheel (2), pinion (5) is fixed on the same axle with two big belt pulleys (6), two big belt pulleys (6) are fixed on the two ends of axle, pinion (5) is fixed on the centre of axle, by two bearings (7) axle is fixed on the frame (4) of head sheave (1) below, so constitutes a simple speed reduction gearing.Motor (9) is a common asynchronous moter, also can select magneto, switched reluctance machines for use.Motor (9) is fixed on the frame (4) of big belt pulley (6) below.Two small belt pulleys (10) are separately fixed on the axle at motor (9) two ends, and link with two big belt pulleys (6) respectively with two belts (8).Be fixed on same axle by two head sheaves (1) and a gear wheel (2) and go up the compound integral body of formation, the two ends of axle are fixed on the top of frame (4) by bearing (3).Flexible driving band (11) can be wire rope, also can be the steel wire bandlet that flexible driving band (11) is walked around head sheave (1), and an end is connected with sucker rod (12), and the other end is connected with counterweight (13).The control cabinet (14) of motor (9) is fixed on the bottom of frame (4), by the rotating of control motor, drives the upper and lower reciprocating motion of sucker rod through speed reduction gearing, realizes the purpose of oil pumping.
