Abstract
The present invention relates to a combined-acting wheel pull-rod type oil pumping machine in an oil extraction machine, which is composed of a lifting mechanism of a combined-acting wheel, a speed reduction device, a crank and connecting rod mechanism and a gas balance system, wherein the combined-acting wheel is a fan-shaped wheel, and the extension part of the combined-acting wheel is hinged with a pull rod. The other end of the pull rod is hinged with a machine frame; the crank and connecting rod mechanism drives the lifting mechanism of the combined-acting wheel to make reciprocating rectilinear motion along a sliding guide. Simultaneously, the combined-acting wheel is limited by the pull rod to correspondingly rotate. The fan-shaped wheel realizes long stroke oil extraction operation in composite motion; the present invention has the advantages of light and artful volume, long service life, simple structure and convenient transportation, installation and maintenance, and is suitable for various oil fields; in addition, the working stroke of the present invention ranges from five to eight meters.
Description
The invention belongs to no beam type long stroke combined-acting wheel pull-rod type pumping unit in the petroleum recovering machinery.
At present, the kind of oil pumper is more both at home and abroad, suitable crude oil in China viscosity reaches greatly in the no beam type long stroke pumping unit of deep well oilfield use, better performances as Chinese patent 89205502,2 compound wheel oil-pumpers, no beam type air balanced pumping unit such as it and other chain type oil pumps, slip wheel type oil pumping unit relatively, its novel structure, in light weight, the efficient height.But in use exist the application life because of wire rope, and directly influenced the reliability of oil pumper work, in addition, although oil pumper weight is lighter, volume is big, makes troubles for transportation, installation, maintenance.External oil pumper kind is more, and low frequency long stroke pumping unit such as piston rod type oil pumper see that on the whole also to have volume big, the problem that cost is high.
For fear of above-mentioned weak point, the object of the present invention is to provide a kind of combined-acting wheel pull-rod type pumping unit, finish long stroke with short frame and recover the oil, substitute wire rope with pull bar, guarantee the oil pumper reliable operation, long service life.Because volume is little, transportation, installation, maintenance are conveniently.
For achieving the above object, technical scheme of the present invention is as follows: combined-acting wheel pull-rod type pumping unit is made up of three parts: i.e. the lifting appliance that constitutes of frame, guide rail, double action wheel assembly and bracket assembly; The actuating unit that reducer and crank-link mechanism constitute, the strength balance sysmte that balance cylinder, brake and gas bag constitute.The each several part mutual alignment is as follows, balance cylinder is installed in rectangle frame central authorities, communicates through the gas bag of pipeline with a side, at the top of balance cylinder installation bracket assembly, roller on around the bracket assembly contacts with the guide rail that is fixed on the frame top, can move up and down along guide rail.The double action wheel assembly comprises double action wheel and double action wheel shaft, is installed in the bracket assembly top by bearing support, and the power output of reducer passes to the double action wheel assembly through the crank linkage.Realize long stroke work in order to reduce oil pumper weight and short frame, the double action wheel is manufactured sectional wheel, the extension of sectional wheel and pull bar one end are hinged, and the pull bar other end and frame are hinged, substitute wire rope with pull bar.
Another scheme is that double action wheel is one with the axle weldering, and the double action wheel shaft is a hollow shaft, the suit axle that moves about in the axle, the yoke at a two ends of moving about respectively with rod hinge connection, in the middle of the axle that moves about, self-aligning bearing is housed, be connected as a single entity through bearing and double action wheel shaft.Adopt this structure.Guarantee double action wheel hoisting mechanism when reciprocating, coordination avoids producing stuck phenomenon, just makes it have definite motion.
In order to reduce the complete machine height, it is that reducer and crank-link mechanism are offset to balance cylinder center line one side that another that take refers to execute, distance of crank up misalignment center line of guide rail of oil pumper has just so also been avoided when balance cylinder is worked and reducer is collided.
For transport, installation, maintenance is convenient, combined-acting wheel pull-rod type pumping unit complete machine weight is designed to the long 3.1 meters wide high 9.5-10 rice of 22-2.5 rice of 12-18 ton, is fit to China's full trailer transportation.
In order to further specify architectural feature of the present invention, described below in conjunction with accompanying drawing.
Fig. 1 is the combined-acting wheel pull-rod type pumping unit structural representation
Fig. 2 is the double action wheel shaft and the axle construction schematic diagram that moves about
Among the figure: 1, brake 2, motor 3, V-belt 4, reducer 5, crank-link mechanism 6, frame 7, balance cylinder 8, gas bag 9, pull bar 10, sucker rod 11, polished rod eye 12, wire rope 13, roller 14, carriage 15, guide rail 16, yoke 17, double action wheel 18, hollow shaft 19, self-aligning bearing 20, axle moves about
The course of work of combined-acting wheel pull-rod type pumping unit
At first unclamp hand-operated brake, gas bag is carried out qi of chong channel ascending adversely, when the gas bag internal gas pressure reaches certain numerical value, the interior gas of cylinder will promote double action wheel hoisting mechanism and move upward, the connecting rod at simultaneously double action wheel shaft two ends moves thereupon and spurs crank up, when observing crank and go to horizontal level, to close immediately air pump and stop inflation, this moment, the cylinder internal gas pressure was enough. But starter motor then, the running of driven by motor decelerator is contained in the toggle running on the decelerator, And drive double action wheel hoisting mechanism and pump, namely the guide rail along the frame top pumps, and double action wheel simultaneously pining down of tension member is done accordingly rotation. Pumping rod rope-suspending device is fixed on the wheel rim of double action wheel by steel wire rope, and sucker rod is pumped by the pulling of steel wire rope and finishes the oil pumping operation. The actual displacement of sucker rod equals the straight-line length of carriage and felly rotates the radian sum, reached the purpose of long stroke oil pumping operation, if in addition in use correct grasp and the pressure of adjusting in the gas bag makes counterbalance effect reach best, thereby realizes energy-conservation.
Advantage of the present invention: combined-acting wheel pull-rod type pumping unit absorbs the advantage of other oil pumpers, new design is structurally arranged, improve and set up the combined-acting wheel pull-rod type hoisting mechanism, with lighter complete machine weight, shorter frame realizes recovering the oil than long stroke, perfect gas balance sysmte, make energy-saving effect the best, be convenient to simultaneously transportation, I﹠M, wide adaptability.
