Abstract
The utility model relates to an oil pumping machine with a crank and a drum. The utility model belongs to the technical field of an oil pumping machine of petroleum machinery. The utility model solves the problem that the existing oil pumping machine can not simultaneously have long stroke, low stroke frequency, reliability and durability. The utility model utilizes a reduction box and a crank link mechanism of a moving beam oil pumping machine. A cross beam, a gear rack and a gear wheel drive a drum to rotate in a positive direction and an opposite direction. A rope hanger leads an oil pumping rod to pump oil from top to bottom in a traction mode back and forth. The utility model is a novel oil pumping machine which has the advantages of firmness, durability, high efficiency, energy saving, long stroke and low stroke frequency.
Description
Affiliated technical field
The utility model belongs to the pumping unit technical field of petroleum machinery.
Background technique
The long stroke low jig frequency of pumping unit is desirable oil production technology.It can improve oil production system efficient significantly by reducing loss of plunger stroke.Developed the pumping unit of diversified long stroke low jig frequency for this reason.Hydraulic pumping unit for example, chain drive pumping unit, reel-type pumping unit etc.These pumping units can both be realized the long stroke low jig frequency, and have obtained the energy-saving effect that improves oil production system efficient 30-40%.But on reliability and durability,, do not push open as yet so far far away from beam-pumping unit.Study the pumping unit that a kind of connecting rod adds cylinder type for this reason, be called for short the formula pumping unit that circumnutates, realized the oil production technology of long stroke low jig frequency preferably.
Summary of the invention
Can not possess simultaneously in order to overcome existing pumping unit, the deficiency of long stroke low jig frequency, reliability and durability, the utility model provides a kind of formula pumping unit that circumnutates, it adopts the connecting rod of beam-pumping unit, effectively inherit its reliability and durability, enlarged the stroke of pumping unit simultaneously again by drum mechanism built.
The utility model is the reliability of solution long stroke pumping unit and the problem of durability, and the technological scheme that provides is (referring to an accompanying drawing): going up at the support (5) of horizontal positioned speed reducer (1), motor (4) are installed, is angle band transmission between them; At the two ends of reduction gearbox output shaft key connecting crank and equilibrium block (2), be connected with bearing pin by bearing between crank and the connecting rod (7), the upper end of connecting rod is connected by the end axle of bearing with crossbeam (8), constitutes connecting rod; Vertical pin joint mobile jib (3) on the support before speed reducer, the top of mobile jib is hinged with pair bar (6), and the lower end of pair bar and the rear portion of support are hinged, form a leg-of-mutton mobile jib support system; Two parallel rack bars of pin joint (9) under crossbeam, and insert the mobile jib inner chamber respectively, gear (11) interlock in tooth bar and the mobile jib top case; Gear and reel (10) are fixedly mounted on the same axis, and reel is placed in the middle, and gear is in both sides, and drum diameter is greater than gear diameter, the two ends of spool shaft by Bearing Installation within the case of mobile jib top; Wire rope with rope hanger (12) is fixed on the reel at last.Like this, behind actuating motor, connecting rod drives tooth bar, the gear driven reel is done forward and reverse rotatablely moving, and reel is up and down reciprocatingly pumped by wire rope and rope hanger traction sucker rod.Because the connecting rod of intact employing beam-pumping unit, it has higher reliability and durability certainly; Because rack bar is inserted in the mobile jib inner chamber, the double fuel tank of doing of mobile jib inner chamber can guarantee that tooth bar, gear have sufficient lubricating, and has enough spaces can supply tooth bar, gear to select enough Intensity Design, so rack pinion also can not influence the durability of this pumping unit; Because drum diameter greater than gear diameter, then is easy to realize long stroke; As for low jig frequency, can be achieved by selecting slow-revving motor or increase variator drive ratio.
The beneficial effects of the utility model: can realize the long stroke low jig frequency, reduce loss of plunger stroke, improve oil production system efficient significantly, low jig frequency can reduce the number of times of alternating stress, the working life of prolongation machine, bar, pump and well workover cycle, and inherited the reliability and the durability of beam-pumping unit.
Description of drawings
Fig. 1 is the profile of formula pumping unit of circumnutating.
Fig. 2 is that the local A of Fig. 1 is to view.
Among the figure, 1. speed reducer, 2. crank and equilibrium block, 3. mobile jib, 4. motor, 5. support, 6. pair bar, 7. connecting rod, 8. crossbeam, 9. rack bar, 10. reel, 11. gears, 12. rope hangers.
Embodiment
Embodiment of the present utility model, as shown in drawings: the beam-pumping unit of existing various models all can transfer parts of the present utility model to except that walking beam, horse head and intermediate support assembly.General body is all made by support and the hinged form of mobile jib, and regulates the mobile jib inclination angle by paying bar, so that the usefulness of installation and well workover.The wire rope of rope hanger is the weakest link in the utility model, should make being convenient to change construction of wire rope on reel; Preferably adopt and be contained in coaxial drum diameter and obtain big stroke greater than the method for gear diameter.Implement critical component of the present utility model and also be crossbeam (8), need make the equalizer of triple axle, just can obtain better success.
Claims (2)
1. the formula pumping unit that circumnutates is gone up installation speed reducer (1), motor (4) at the support (5) of horizontal positioned, is angle band transmission between them; At the two ends of reduction gearbox output shaft key connecting crank and equilibrium block (2), be connected with bearing pin by bearing between crank and the connecting rod (7), the upper end of connecting rod is connected by the end axle of bearing with crossbeam (8), constitute connecting rod, it is characterized in that: vertical pin joint mobile jib (3) on the support before speed reducer, the top of mobile jib is hinged with pair bar (6), and the lower end of pair bar and the rear portion of support are hinged, form a leg-of-mutton mobile jib support system; Two parallel rack bars of pin joint (9) under crossbeam, and insert the mobile jib inner chamber respectively, gear (11) interlock in tooth bar and the mobile jib top case, gear and reel (10) are fixedly mounted on the same axis, reel is placed in the middle, and gear is in both sides, and drum diameter is greater than gear diameter, within the case of mobile jib top, the wire rope of rope hanger (12) is fixed on the reel by Bearing Installation at the two ends of spool shaft.
