The utility model has simple structure, small size, light weight, reliable performance, notable energy-saving effect and long service life. Workover can be conveniently carried out; in addition, balance adjustment and working parameter adjustment can be done conveniently and quickly.
Description
Technical field: the utility model relates to oil extraction machinery and equipment, belongs to the improvement of ground oil production equipment oil pumper, particularly symmetrical balance commutation oil pumper.
Background technology: oil pumper is the main ground installation of recover petroleum.Advantages such as at present, in various types of oil pumpers, using maximum is beam pumping unit, and it has simple in structure, and is reliable, and workover treatment is convenient.But because it is subjected to the restriction of design feature own, system effectiveness is not high, and required motor power is bigger, the nominal torque height of reducer, and causing recovers the oil has high input the cost for oil production height; Stroke relies on manual adjustment, wastes time and energy.In order to overcome the shortcoming of beam pumping unit, people have invented tower shelf type oil pumping machine again, and its advantage is energy-conservation, and it is convenient to adjust running parameter.But because structure is limit, frame is near apart from the distance of well head, needs whole telephone-moving, inconvenient operation during well workover; The well head keeping warmth space is little.Measuring indicator diagram needs other adding set, operating difficulties, and the rope sheave radius of curvature is little, and wire rope is short application life.
Summary of the invention: the purpose of this utility model is to provide a kind of symmetrical balance commutation oil pumper, not only simple in structure, machine volume is little, and is in light weight, reliable, workover treatment is convenient, and balance adjustment and running parameter is easy to adjust quick, and consumed power is few, the system effectiveness height, energy-saving effect is obvious, long service life.
The purpose of this utility model is achieved in that a kind of symmetrical balance commutation oil pumper, be included in the motor of installing on the frame, brake, the horse head body that is hung with polished rod eye is installed on reduction box and the walking beam, motor-operated reduction box is installed on the platform of frame top, the output shaft of reduction box is connecting back shaft by shaft coupling, on back shaft affixed before, the walking beam of postbrachium equal in length, the two ends of walking beam are installed with work horse head and balance horse head respectively, the articulated work horse head of hanging scroll of the walking beam end setting of work horse head wherein is housed, and by the locating shaft that this end the is provided with horse head relative fixed of to work, wire rope hanging fixing on the balance horse head bascule, and the intelligent electric appliance switch board is installed on frame.
Because the utility model complete machine adopts symmetrical balance, back shaft and walking beam combine as a whole, cancelled the traditional quadric chain of beam pumping unit, the rotation direction of work horse head is by the decision of the rotation direction of motor, and the horse head commutation transfers realization by motor is positive and negative.Can calculate the load moment of oil pumper according to the indicator card curve of oil well, determine counterweight, make oil pumper reach more satisfactory counterbalance effect according to load moment.Because arm lengths is shorter than the walking beam arm of beam pumping unit before and after the symmetrical balance walking beam of the present utility model, under the situation of identical load and counterweight, required rotating torque is little, thereby consumed power is few, and energy-saving effect is obvious.Motor adopts Based Intelligent Control, and up-downgoing speed can be regulated respectively.Inertia force is little, and transmission link is few, thereby the system effectiveness height.But stroke jig frequency step-less adjustment only need touch the button and can finish.Because arm lengths is shorter before and after the walking beam, can increase the pivot angle of walking beam during work, thereby can increase the radius of curvature of horse head, increased the application life of wire rope.Since the work horse head by hanging scroll and locating shaft relative fixed in the walking beam end, when carrying out workover treatment, horse head is forwarded to the center of circle of the center of circle, locating shaft of hanging scroll and horse head center of gravity when the position of straight line, locating shaft can be extracted out, walking beam rotates up, the horse head center of gravity is rotated around hanging scroll, makes horse head away from the well head center line, abdicates the locus and is convenient to workover treatment.
Description of drawings: Fig. 1 is a main TV structure schematic diagram of the present utility model, and Fig. 2 is a side-looking structural representation of the present utility model.
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing, a kind of symmetrical balance commutation oil pumper, be included in motor, the brake installed on the frame, the horse head body that is hung with polished rod eye is installed on reduction box and the walking beam, the reduction box 11 that motor 10 drives is installed on the platform at frame 5 tops, and motor 10 is a switched reluctance motor; The output shaft of reduction box 11 is connecting back shaft 12 by shaft coupling, the walking beam 1 that affixed forward and backward arm lengths equates on back shaft 12, the two ends of walking beam 1 are installed with work horse head 2 and balance horse head 3 respectively, the hanging scroll 9 articulated work horse heads 2 that walking beam 1 end of work horse head 2 is provided with wherein are housed, and by the locating shaft 8 of this end setting horse head 2 relative fixed of will working.Hard-wired wire rope hanging polished rod eye 7 on work horse head 2, and wire rope fixing on balance horse head 3 is hung bascule 4, and bascule 4 is installed with balancing weight for hanging on the sinker.Counterpoise that can be definite according to load moment manually increases and decreases balancing weight, comes adjustment.Intelligent electric appliance switch board 6 is installed on the base of frame 5, and the running parameter during the utility model work can directly be exported by intelligent electric appliance switch board 6.
