Description

Technical Field

[0001] This utility model relates to the field of oil and gas development technology, and in particular to a safety protection device for an oil pumping unit. Background Technology

[0002] Pumping units are critical equipment in oil extraction. A power unit drives a reducer, converting high-speed rotation into low-speed crank rotation. This crank rotation, via a connecting rod-walking beam mechanism, further converts the rotary motion into the reciprocating motion of the pump head, driving the deep well pump. During operation, moving parts of the pumping unit, such as the crank, counterweights, and connecting rods, are prone to accumulating debris like weeds and sand, leading to equipment wear, malfunctions, and even safety accidents. Existing protective devices mostly protect the gearbox and motor, failing to provide comprehensive protection for moving parts like the crank and counterweights. Utility Model Content
