Abstract

The invention relates to a beam pumping unit, and in particular relates to a pulley stroke-lengthening beam pumping unit which comprises a frame, a walking beam, a horse head, an upper movable pulley, a lower movable pulley, a crossbeam connecting rod, a load bearing belt, a belt hanger, a motor, a speed reducer and a crank, wherein a transmission device is mounted between a power output shaft ofthe motor and a power input shaft of the speed reducer; the crank is mounted on a power output shaft of the speed reducer; the middle of the walking beam capable of swinging up and down is hinged at the top of the frame; the upper end of the crossbeam connecting rod is hinged on the right part of the walking beam; and the lower end of the crossbeam connecting rod is hinged on the crank. The pulley stroke-lengthening beam pumping unit provided by the invention is of a reasonable and compact structure and convenient to use, can realize long stroke on a relatively small mechanical structure through the upper movable pulley and the lower movable pulley, meets the need for large-displacement oil production, has high reliability, saves the raw materials for manufacturing a pumping unit, reducesenergy consumption of production, regulates balance, ensures safe, convenient and quick operation, and can be used as a conventional stroke pumping unit by replacing the horse head or load bearing belt.

Description

technical field [0001] The invention relates to a beam pumping unit, which is a pulley-extended beam pumping unit. Background technique [0002] The beam pumping unit is the main equipment for oil production, and generally includes a rope hanger, a donkey head, a beam, a frame, a connecting rod beam, a reducer, a crank, a counterweight, a belt, an electric motor, a base and a foundation; The following disadvantages: short stroke, small displacement, high energy consumption, inconvenient operation, especially not suitable for the exploitation of heavy oil. Contents of the invention [0003] The present invention provides a pulley-extended beam pumping unit, which overcomes the shortcomings of the prior art and can effectively solve the problems of short stroke, small displacement, high energy consumption and inconvenient operation of the existing beam pumping unit. question. [0004] The technical solution of the present invention is achieved through the following measure...
