Abstract

The present application discloses a cylinder-driven swing arm type oil pumping unit, which includes a tower, and a cylinder and a swing arm type reversing device driven by the cylinder are arranged in the tower, and the cylinder is fixed on the frame of the swing arm type reversing device The piston of the cylinder expands and contracts in the horizontal direction; the swing arm type reversing device, the cylinder drives the swing arm type reversing device to move, and the swing arm type reversing device drives the counterweight device together with the wire rope, and then drives the sucker rod to reciprocate up and down. In this application, the cylinder drives the swing arm type pumping unit, and the swing arm type reversing device driven by the cylinder drives the counterweight device to move up and down, and then drives the sucker rod to reciprocate up and down through the steel wire rope bypassing the sky wheel, so as to realize the reciprocation of the suspension point of the pumping unit Movement, the up and down uniform reciprocating motion of the swing arm reversing device can ensure that the piston of the oil well pump moves at a constant speed most of the time, which can effectively reduce the energy loss during the oil pumping process and meet the requirements of energy saving.

Description

technical field [0001] The application relates to an oil pumping unit, in particular to a cylinder-driven swing arm type oil pumping unit, which belongs to the technical field of engineering machinery. Background technique [0002] With the continuous development of oil fields and the continuous increase of mechanical oil recovery oil fields, the demand for pumping units in oil fields is also increasing. Developing high-efficiency, energy-saving, and highly reliable pumping units is an urgent task for the petroleum machinery and equipment industry, and it is also the goal that manufacturers have always pursued. [0003] Traditional pumping units are mostly beam pumping units. For example, the application number is 201510175769.1, and the patent application for the invention name is beam pumping unit, which discloses a beam pumping unit, including a bracket and a reducer. . At the other end, the balance block is fixed on the balance arm, one end of the support rod is movabl...
