Abstract

The invention discloses a double-roller tower type oil-pumping unit device. A roller type speed reducer drives a driven roller to rotate through an opening belt, one end of the opening belt is connected with a weight box, the other end of the opening belt is connected with a suspension assembly, the other end of the suspension assembly is connected with one end of a belt clip, the other end of the belt clip is connected with one end of an oil pumping rod, the other end of the oil pumping rod is movably connected with an oil pumping unit, and a brake is connected with a coupler assembly; an output shaft of an electric motor is connected with a belt wheel shaft through the coupler assembly, a driving synchronous belt wheel is installed on the belt wheel shaft, a driven synchronous belt wheel is installed on an input shaft of the roller type speed reducer, and synchronous belts sequentially are wounded the driving synchronous belt wheel and the driven synchronous belt wheel and then are rotationally driven to connect; and guide wheels are installed on both sides of the weight box, a guide rail is fixed on a rack, and the rack is fixed on a concrete foundation by bolts. The double-roller tower type oil-pumping unit device has the characteristics of simple structure, good stability, non-skid performance of the belts, long stroke, low stroke frequency and long fatigue service life, is convenient to use, is easy to regulate strokes and stroke frequencies and is widely used for the oil extraction industry.

Description

technical field [0001] The patent of the present invention relates to the field of pumping units, in particular to a double-drum tower pumping unit device. Background technique [0002] There are mainly two problems in the existing single-drum pumping unit product. One is that the center of gravity of the whole machine is outside the frame (when there is no counterweight in the counterweight box), and the stability is poor. The 2nd, there is no anti-slip measure for the drum, and the belts for hanging the counterweight box and the sucker rod are easy to slip and other defects. Contents of the invention [0003] The object of the present invention is to provide a double-drum tower pumping unit with simple structure, convenient use, good stability and no slippage of the belt. [0004] In order to overcome the deficiencies in the prior art, the technical solution of the present invention is solved in this way: a double-drum tower pumping unit, the device is composed of a br...
