Abstract
The utility model relates to an adjustable support arm of a single-crank double pumping unit holder, which mainly solves the problems of time waste, labor waste, and too many mechanism devices which need to be used, when the existing pumping holder regulates the position of a pumping rod relative to a well. The utility model is characterized in that the middle part of one side of a holder (1) is hinged with a support arm (2) which is provided with an adjusting rod (3) inside; the adjusting rod (3) is provided with a screw cap (4), and the upper end of the support arm (2) is connected with a fixed pulley (5) which is positioned on one plane with two fixed pulleys on the holder (1), and a draw rod (6) is connected between the upper end of support arm (2) and the holder (1). The adjustable support arm of a single-crank double pumping unit holder has the characteristics of easy adjustment, labor saving and time saving.
Description
Technical field:
The utility model relates to the used support of oil pumper in the oil recovery field, oil field, especially single-crank multiple-stroke oil pumper support adjustable extension arm.
Background technology:
Along with Oilfield developing, technology constantly develops, mechanical oil recovery equip ment from the beam pumping unit to the submersible electric pump, screw pump etc., of a great variety, to adapt to the needs of different productive lives.At present, the oil pumper that is used for artificial lift is based on beam pumping unit, is divided into conventional type beam pumping unit, prefix type beam pumping unit, out-phase type beam pumping unit and two horse head type beam pumping unit according to the difference of the structure of the crank quadric chain of horse head.The support of these oil pumpers is wasted time and energy when regulating sucker rod and pithead position, and efficient is low, and employs the plant equipment multinomial, thereby has increased manufacturing cost, is unfavorable for the oil field development requirement.
The utility model content:
When having oil pumper bracket adjustment sucker rod and pithead position now in order to solve, waste time and energy and employ the many problems of plant equipment, the utility model provides a kind of single-crank multiple-stroke oil pumper support adjustable extension arm, and this single-crank multiple-stroke oil pumper support adjustable extension arm has easy to adjust, time saving and energy saving characteristics.
The technical solution of the utility model is: this single-crank multiple-stroke oil pumper support adjustable extension arm comprises support, at support one middle side part hinge support arm is arranged, adjusting rod is arranged in the support arm, nut is arranged on the adjusting rod, the support arm upper end is connected with fixed pulley, and two fixed pulleys on fixed pulley and the support are on a plane; Be connected with pull bar between support arm upper end and support.
Support arm in the such scheme and support hinge respectively have two pull bars, between two pull bars by the positive and negative adapter sleeve that has been threaded.
The utlity model has following beneficial effect: place near the steps single-crank multiple-stroke oil pumper support adjustable extension arm is owing to take such scheme, because of the adapter sleeve that has been threaded on nut 4 and the pull bar is arranged on the support arm, so just can regulate flexible rod and pithead position by rotary nut and adapter sleeve, make flexible rod be positioned at the well head center, time saving and energy saving, easy to adjust, and need not employ plant equipment, improved operating efficiency, reduce cost of production, guarantee the ordinary production of oil pumper.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-main body among the figure, 2-linking arm, 3-support arm, 4-nut, 5-fixed pulley, 6-pull bar, 7-adapter sleeve.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this single-crank multiple-stroke oil pumper support adjustable extension arm comprises support 1, at support 1-middle side part hinge support arm 2 is arranged, adjusting rod 3 is arranged in the support arm 2, nut 4 is arranged on the adjusting rod 3, and support arm 2 upper ends are connected with fixed pulley 5, and two fixed pulleys on fixed pulley 5 and the support 1 are on a plane; Support arm 2 and support 1 hinge respectively have 6 on two pull bars, 5, two pull bars by the positive and negative adapter sleeve 7 that has been threaded.Because of the adapter sleeve 7 that has been threaded on nut 4 and the pull bar 6 is arranged on the support arm 2, so stretching and length with regard to adjustable support arm 2 and pull bar 6 by rotary nut 4 and adapter sleeve 7, flexible rod and pithead position have also just been regulated, make flexible rod be positioned at the well head center, eliminated the eccentric wear phenomenon.Thereby reach purpose time saving and energy saving, easy to adjust, and need not employ plant equipment, improved operating efficiency, reduce cost of production, guarantee the ordinary production of oil pumper.
