Abstract
A beam-pumping unit comprises a support assembly installed on a base. A walking beam support is arranged at the top end of the support assembly. A walking beam is arranged on the walking beam support. A horsehead is arranged at one end of the walking beam. A beam hanger is arranged on the horsehead through a belt. A motor, a speed reducer, a crank device and a connecting rod device are further arranged on the base. A brake assembly is arranged on the motor. A suspension arm assembly is arranged on the end portion of the other end of the walking beam. A beam is arranged at the bottom of the other end of the walking beam. One end of the connecting rod device is hinged to the beam and the other end of the connecting rod device is hinged to the crank device. A balancing weight is arranged on one end portion of the suspension arm assembly. The crank device is connected with an output shaft of the speed reducer. The speed reducer is connected with the motor through a belt. The speed reducer is a three-level speed reducer. According to the beam-pumping unit, the three-level speed reducer is adopted, so that the beam of the walking beam is short, the three-level speed reducer is a three-level four-shaft speed reducer, the speed ratio of the three-level speed reducer is 1:63, the rotating speed per minute is 0.1, the rotating speed is low and easy to control, and the beam-pumping unit is suitable for a shallow well, a low-seepage well or an oil well with a small amount of oil and with the requirement for speed control.
Description
Technical field
The utility model belongs to the oil pumper field, relates in particular to a kind of beam pumping unit, and it turns than greatly, and rotating speed is low, is applicable to the oil well that the oil masses such as shallow well, hyposmosis well seldom need control rate.
Background technology
Current beam pumping unit, its walking beam is rack-mount by crossbeam, walking beam is shorter, an end at walking beam arranges horse head, the other end is connected with balancing weight by connecting rod, balancing weight and connecting rod all are arranged on the support both sides, and balancing weight is connected with reducer by crank, and reducer adopts the two circular arc reducers of three axle two-stages.This structure crossbeam is long, and the speed ratio of reducer is 31:778, and speed ratio is little, and speed is fast, and bad control is dangerous.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency a kind of beam pumping unit is provided, and its speed ratio is 1:63, and speed ratio is large, and rotating speed is low, high safety.
For achieving the above object, the utility model is by the following technical solutions:
A kind of beam pumping unit, comprise the bracket assembly be arranged on base, the walking beam support is arranged on the top of bracket assembly, walking beam is arranged on the walking beam support, an end at walking beam is provided with horse head, polished rod eye is arranged on horse head by belt, also be provided with motor on base, reductor, crank device and linkage, be provided with brake assembly on motor, end at the walking beam other end arranges boom assembly, walking beam other end bottom is provided with crossbeam, one end of linkage and the hinged other end of crossbeam and crank device are hinged, the boom assembly end is provided with balancing weight, crank device is connected with the output shaft of reductor, reductor is connected by belt with motor, described reductor is triple reduction gear.
Above-mentioned beam pumping unit, reductor is three grades of circular-arc gear decelerators.
Above-mentioned beam pumping unit, bracket assembly is fixed on base by stone bolt.
Above-mentioned beam pumping unit also is provided with bracing frame on base, and motor, reductor and crank device all are arranged on bracing frame.
Above-mentioned beam pumping unit, also be provided with guardrail on described base, motor, reductor and crank device all are arranged in guardrail.
Adopt technique scheme, the utility model has following advantage: the utility model walking beam is long, establish the horse head other end at an end of walking beam crossbeam and arm are set, at arm end establishing pouring weight, walking beam is hinged by connecting rod and crank, and employing triple reduction gear, the crossbeam of walking beam can arrange shorter like this, triple reduction gear is three grade of four axle reducer, its speed ratio is 1:63, and within one minute, rotating speed is 0.1, and rotating speed is low, speed is easily controlled, and is applicable to the oil well that shallow well, hyposmosis well or oil mass seldom need control rate.
