Power balance digitization automatic control oil pumping method and oil extraction robot

The invention relates to the technical field of beam-pimping units, in particular to a power balance digitization automatic control oil pumping method and an oil extraction robot. The oil extraction robot comprises a main motor, a speed reducer, a crank, a connecting rod, a walking beam, a balance suspension arm, a support, a horse head, a base, a braking device, a beam hanger, a load sensor, a stroke process measurer, a safety limiting device and a digitization control cabinet. The oil extraction robot has the advantages of being safe and reliable. The balance and the jig frequency of a pumping unit are automatically optimized and adjusted, the well yield is fully developed, the efficiency of a well system of the pumping unit is improved, the seamless access of the well system to a computer network system is achieved, data remote transmission and remote well opening and closing control are achieved, operation is simplified, convenience and fastness are achieved, manpower is saved, energy conservation and emission reduction are achieved, and the economic benefits are increased.
