Abstract

The utility model relates to a linkage oil pumping machine. One end of a crank is connected with an output shaft of a speed changing box; a wire rope is fixed at the other end of the crank; both ends of the wire rope respectively pass round a pulley wheel to be connected with an oil pumping rod; the upper margin of the pulley wheel and the output shaft of the speed changing box are at the same horizontal line. The utility model reduces the device investment and the cost of oil extraction and is suitable for being used in oil fields with large density of oil wells.

Description

The interlock pumping unit

The utility model relates to a kind of petroleum recovering equipment; Be meant the interlock pumping unit that can drive two mouthfuls of oil well oil-pumpings simultaneously especially; It is applicable to the big oil field of density, oil well position.

At present, the oil field generally all is to exploit oil in can not whale with a pumping unit on a bite oil well, for energy efficient with increase field output, people designed many in pumping units, these pumping units only are applicable to the single port oil well oil-pumping.Improve and the output in stable oil field, increase that to beat a large amount of encryption oil wells be one of effective measures, promptly in the scope of several meters or tens meters, get the oil well more than two mouthfuls or two mouthfuls.

The purpose of this utility model just provides a kind of interlock pumping unit that drives two mouthfuls of oil wells simultaneously; These facility have tangible characteristics of energy saving, and can save a large amount of equipment investments and maintenance expenses.

The purpose of this utility model is achieved in that a kind of interlock pumping unit, form by motor, gearbox, crank, wire rope, pulley, pulley bracket, electric machine support, sucker rod, motor, gearbox are installed on the electric machine support, pulley is installed on the pulley bracket, electric machine support is arranged between two pulley brackets, one end of crank is connected with the output shaft of gearbox, wire rope is fixed on the other end of crank, the two ends of wire rope are walked around pulley respectively and are connected with sucker rod, and the upper limb of pulley and the output shaft of gearbox are on same horizontal line.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is another example structure schematic representation of the present utility model.

Below in conjunction with drawings and Examples the utility model is described further.

As shown in Figure 1: pulley 7 is installed on the pulley bracket 5, electric machine support 6 is arranged between two pulley brackets 5, motor 1, gearbox 2 is installed on the electric machine support 6, one end of crank 3 is connected with the output shaft of gearbox 2, wire rope 4 is fixed on the other end of crank 3, the two ends of wire rope 4 are walked around pulley 7 and sucker rod 8 respectively, sucker rod 9 connects, the output shaft of the upper limb of pulley 7 and gearbox 2 is on same horizontal line, sucker rod 8, sucker rod 9 is separately positioned in the oil well mouth 10, the stroke of sucker rod 8 or sucker rod 9 equals 2 times of crank 3 length, and sucker rod 8 is just opposite with the movement direction of sucker rod 9.

Fig. 2 is another example structure schematic representation of the present utility model, in order to overhaul conveniently, motor 1, gearbox 2 is installed in lower, and crank 3 is improved certain altitudes, and the upper limb that makes the fixed end of crank 3 and pulley 7 is on same horizontal line.

The utility model only needs a motor, a gearbox just can drive two mouthfuls of oil well oil-pumpings simultaneously, has reduced equipment investment, reduces cost of oil production, is applicable on the big oil field of oil well position density.
