The invention discloses a double-faced toothed chain tower-type pumping unit. A double-faced toothed chain sequentially bypasses a driving sprocket, a jockey sprocket and a driven sprocket, and is respectively meshed with the three sprockets; one end of the double-faced toothed chain is fixedly connected with a weight box through a first chain clip, and the other end of the double-faced toothed chain is fixedly connected with a sucker rod hanging box through a second chain clip; a three-phase asynchronous motor drives the driving sprocket to rotate through a speed reducer; the driving sprocket simultaneously drives the sprockets to rotate through the double-faced toothed chain; the weight box reciprocates up and down along the guide rail through the jockey sprocket; the sucker rod hanging box drives a sucker rod to reciprocates up and down in an oil sucker; and the rise of the sucker rod is the oil pumping stroke, and the fall of the sucker rod is the idle stroke. The invention has the characteristics of long service life, stable reversing, adjustable frequency of strokes, good stability, fatigue resistance, high efficiency, energy saving and the like. Compared with the beam-pumping unit, the invention enhances the efficiency by about 20%; and compared with the tower-type pumping unit, the invention enhances the efficiency by about 10%. The invention is widely used in oil extraction wells in oil industry.
Description
Technical field [0001] The invention relates to the field of oil pumping units in the petroleum industry, in particular to a double-sided toothed chain tower pumping unit device. Background technique [0002] The existing tower pumping unit products have many problems. One is the life of its flexible parts, the other is the impact of the commutation process, and the third is the adjustability of the stroke. For example, the applicant applied for the patent No. ZL200920245101.X for "a double-sided synchronous chain tower pumping unit" patent. The toothed chain of this patent uses a movable pulley block and a fixed pulley block. The problem with meshing transmission is that there are many pulleys. There are 6 pulleys in total. The toothed chain is long. The total length of the two toothed chains is 120m. Because the lower frame of the driving pulley is stressed, there is a frame for the 12-type pumping unit. The total pressure produced by the sucker rod and the balance weight box...
