Intelligent adjustment device for transmission system of oil pumping unit

Abstract

The invention discloses an intelligent adjustment device for a transmission system of an oil pumping unit. The intelligent adjustment device comprises a fixed base, a transversal adjustment device installed on the fixed base, and a longitudinal adjustment device installed on the transversal adjustment device, wherein the transversal adjustment device comprises guide rails, slide seats and hydraulic devices; the guide rails are fixedly installed on the fixed base; one slide seat is slidably arranged on each guide rail; one hydraulic device used for pushing each slide seat to slide relative to the corresponding guide rail is arranged between the slide seat and the corresponding guide rail; two slide rails which are arranged in parallel are arranged between the two corresponding slide seats; and the longitudinal adjustment device comprises a drive base, a driven base, the slide rails, a lead screw, nuts and motors. The adjustment device is capable of realizing automatic tensioning of a belt of the oil pumping unit, thus reducing the workload of an operator, and increasing the working efficiency; and moreover, stalling and alarming of an oil pumping motor are realized after the belt is broken, the operation is intelligent and convenient, and energy waste is reduced.

Description

technical field [0001] The invention relates to the technical field of oil field exploitation equipment, in particular to an intelligent adjustment device for a pumping unit transmission system. Background technique [0002] Belt transmission is a common and low-cost power transmission device, which has the characteristics of smooth movement, cleanliness and low noise, so many machines use belt transmission as the power transmission device, because the belt used in belt transmission has certain elasticity Yes, so after a period of use, the elasticity of the belt will decrease and the length will become longer. If the positions of the driving wheel and the driven wheel remain the same, the belt will become looser and looser, which will affect the power transmission. Therefore, it is generally necessary to make the belt looser. The belt tightened again. [0003] In oil extraction equipment, the pumping unit is the most common oil pumping equipment. The oil is pumped out of th...

AI Technical Summary

Problems solved by technology

[0003] In oil extraction equipment, the pumping unit is the most common oil pumping equipment. The oil is pumped out of the well by pressurization. The pumping unit is mainly composed of beam-connecting rod-crank mechanism, motor and auxiliary equipment, and the pumping unit In the work, the power transmission is also realized through belt transmission. The motor base of the pumping unit is a fixed structure. The weight of the motor is too troublesome to install. The belt needs to be replaced regularly during the oilfield mining process. The replacement process of the belt needs to move the motor. , which requires multiple workers to coordinate operations, which is time-consuming and labor-intensive, greatly increasing labor costs, low work efficiency, and affecting the normal production of oil wells
