Description

Technical Field

[0001] The utility model relates to the technical field of vertical oil pumping units, in particular to a novel vertical oil pumping unit. Background Art

[0002] A pumping unit, commonly known as a "kowtow machine," is a machine used in oil extraction. It is the primary lifting device in a rod pumping system. Depending on whether or not it has a walking beam, it can be divided into beam-type and beamless types. Vertical pumping units are heavy-duty, long-duration machines with long pumping strokes, requiring high balance during long-stroke operation. Vertical CNC pumping units are mechatronic "long-stroke, low-stroke" pumping units, representing a perfect integration of modern mechanical manufacturing, control, power electronics, and mechatronics technologies. They utilize a control system to drive the motor. A combined reduction transmission commutates the pumping unit's power source and terminal load, pulling the pumping rod up and down repeatedly. The rod and counterweight form a balance, constantly storing and releasing potential energy, achieving operational balance and effectively achieving a multiplier effect. This addresses the challenges of conventional pumping units, including low mechanical efficiency, difficulty achieving long strokes, and high energy consumption. For example, the Chinese utility model patent CN207526478U discloses a novel vertical oil pumping unit. Conventional vertical units are difficult to fully utilize wire rope transmission because the wire rope requires a larger wheel diameter. If the motor wheel diameter is made very large, the motor cost will be greatly increased. If belt transmission is adopted, it will be difficult to overcome the strong wind environment in the oil field, resulting in serious wear on the wellhead. However, the vertical oil pumping unit described in this utility model can not only make the wire rope transmission fully applicable, but also greatly reduce the cost of motor manufacturing, killing two birds with one stone, thereby greatly reducing the cost of energy-saving oil pumping units and laying a cost foundation for the promotion of energy-saving oil pumping units. The diameter of the sheave only plays a transitional role in the entire transmission, and the wheel diameter can be arbitrarily large, ensuring a high wheel-to-diameter ratio of the transmission parts. The bending of the transmission parts will be greatly reduced, thereby greatly improving the service life of the transmission parts to meet the oil field's requirements for the use of transmission parts.

[0003] The above devices still have certain problems in use. During use, the transmission and lifting of the wire rope requires the motor to provide a large amount of kinetic energy to convert gravitational potential energy, which will consume a lot of energy for oil pumping operations, is not conducive to energy conservation, and has low economic practicality.

The shell is installed on the side of the support seat, several ladders are installed on the side of the shell, and a support plate is installed above the shell. Guardrail A is installed on one side of the support plate, and guardrail B is installed on the other side of the support plate.

[0007] The movable pulley structure consists of a counterweight, a lifting rope A, a pulley A, a force rope A, a force rope B, a wire groove, a lifting motor, a pulley B, a balancing block, a lifting rope B, and an oil pumping equipment.

[0008] Beneficial effects of the utility model:

[0009] This utility model discloses a novel vertical oil pumping unit. The lifting motor is activated by an electronic control device. The lifting motor then drives the pulley located inside the housing of the movable pulley block to rise, and drives the outer pulley of the movable pulley block to descend. The counterweight then rises, and the oil pumping unit descends. The oil pumping unit performs oil pumping operations while descending. The two pulleys in the movable pulley block perform up and down reciprocating motion under the action of the lifting motor, completing the ascent and descent of the oil pumping unit, thereby completing the oil pumping operation. This device replaces the fixed pulley block with a movable pulley block. The movable pulley block consumes less energy during operation, which is beneficial for resource conservation and improved economical practicality. BRIEF DESCRIPTION OF THE DRAWINGS
