Problems solved by technology

[0002] At present, the machinery used for oil pumping and well workover in the oil field is independent, and the crane needs to be used for long-distance hoisting during workover, and the required operating cost is about 50,000 to 80,000 yuan, which greatly wastes manpower, financial resources and material resources
The workover of the pumping workover rig with the patent No. ZL03236696.5 is extremely inconvenient, and because the sucker rod rope and the counterweight rope are wound on the wheel circumference of the sky wheel, the transmission of the torque depends on the connection between the two. Therefore, the traction force is small and the oil pumping efficiency is low

Abstract

The invention discloses a oil extracting well mending machine relating to oil plant mechanic which includes main frame, electric control unit, weight, rope hanger, oil extracting rod, motor , small gear, large gear, head pulley, lifting motor, reduction gear box, guiding wheel and rope hanger is set on top of the balance weight, stand platform is set on top of main frame, guiding wheel, gripper, head pulley clamp, protecting rope passes through gripper fixing on the head pulley on one end and linking to rope hanger on the other end, oil extracting rope links with hanger at one end and on the pulley at the other end, the balance rope links with rope hanger at one end and with the head pulley at the other end symmetric to the oil extracting rope. The lifting rope is fixed on the lifting wheel at one end and the other end with upper guiding wheel stand passing through lower guiding wheel and upper guiding wheel and moving pulley, a weight balancer is set at the bottom of the main frame. The invention is of large oil extracting force and high efficiency which lowers the mending cost by 95 percent, and save energy by 30 to 50 percent; and the work is stable, reliable, durable and all the technique parameter easily adjustable.

Description

Technical field: [0001] The invention relates to oilfield machinery, in particular to a multifunctional oil pumping and workover machine capable of both oil pumping and well workover. Background technique: [0002] At present, the machinery used for oil pumping and well workover in the oil field is independent, and the crane needs to be used for long-distance hoisting during workover, and the required operating cost is about 50,000 to 80,000 yuan, which greatly wastes manpower, financial resources and physical resources. The oil pumping and workover rig with the patent No. ZL03236696.5 is extremely inconvenient for workover, and since the sucker rod rope and the counterweight rope are wound on the circumference of the sky wheel, the transmission of the torque depends on the connection between the two. Therefore, the traction force is small and the oil pumping efficiency is low. Invention content: [0003] The technical problem to be solved by the present invention is to ...
