Tower type oil pumping unit device of single-face tooth-shaped chain

Abstract

The invention discloses a tower type oil pumping unit device of a single-face tooth-shaped chain. An upper transverse beam of a rack of the device is connected with a driven sprocket wheel by a supporting seat of the driven sprocket wheel, a driving sprocket wheel and a tension pulley are connected with a transverse beam at the upper end of the rack by a supporting seat of the driving sprocket wheel, the single-face tooth-shaped chain passes by the driving sprocket wheel, the tension pulley and the driven sprocket wheel sequentially and is engaged with the driving sprocket wheel and the driven sprocket wheel, one end of the single-face tooth-shaped chain is fixedly connected with a weight box by a chain clamp, the other end is fixedly connected with a hanging box of a sucker rod by a chain clamp, a motor drives the driving sprocket wheel to carry out a rotary motion by a speed reducer, the driving sprocket wheel drives the driven sprocket wheel to carry out a rotary motion by the single-face tooth-shaped chain, one end of the single-face tooth-shaped chain pulls the weight box to carry out a reciprocating motion by a guide wheel along a guide rail, the other end of the single-face tooth-shaped chain pulls the hanging box of the sucker rod to drive the sucker rod to carry out a reciprocating motion in an oil pumping device, the ascent of the sucker rod is an oil pumping stroke, and the descent of the sucker rod is an idle stroke. The invention has the characteristics of long stroke, low frequency of the stroke, easy regulation, fatigue resistance, long service life, high efficiency and energy saving.

Description

technical field [0001] The invention relates to the field of oil pumping units in the petroleum industry, in particular to a single-sided toothed chain tower type oil pumping unit. Background technique [0002] There are many problems in the existing tower pumping unit products. One is the life of its flexible parts, the other is the impact of the reversing process, and the third is the adjustability of the stroke times. For example, the applicant applied for on October 16, 2009, and the patent number is ZL200920035071. The problem of the transmission is that there are many pulleys. There are 6 pulleys in total. The total pressure generated by the sucker rod and the balance weight box is about 40 tons, and the production cost is high. Contents of the invention [0003] The purpose of the present invention is to improve on the basis of the patent "a toothed chain tower pumping unit", and now provide a kind of long service life, stable reversing, adjustable stroke times, ...
