Background technique:

The pumping unit is a kind of machinery and equipment for oil extraction, commonly known as "kowtow machine". The oil is pumped out of the well by means of pressurization. The sliding sleeve vibrates; at the same time, the positive check valve is closed, and the variable diameter piston assembly seals the oil. When the pumping unit downstrokes, the oil pipe elastically elongates and moves downward, driving the mechanical unblocking oil extractor to move downward, hitting the slide At the same time, the reverse check valve is partially closed, and the variable diameter piston assembly still blocks the annular oil channel of the oil sleeve, so that the area under the reverse check valve forms a high-pressure area. This movement has a great impact on the oil flow channel in the formation Create a reverse impact. The single-head single-well pumping unit is the most widely used in oil fields now, generally including beam pumping units and hydraulic pumping units, etc. High energy consumption; the existing new pumping unit with one machine and multiple wells has not been widely put into use due to reasons such as complex structure and short service life.

When the utility model is in use, the external power device transmits power to the coaxial crank disc through the first pulley, and the rotational motion of the power device is converted into the reciprocating linear motion of the second rack through the crank disc and the connecting rod. The second rack drives the sucker rod to reciprocate to complete the oil pumping work of the active oil well; at the same time, the second rack transmits the power to the second gear through meshing, and the reciprocating linear motion is converted into rotary motion through the second rack and the second gear , the second gear transmits the power to the coaxial third pulley, the third pulley transmits the power to the second pulley through the timing belt, the second pulley transmits the power to the coaxial first gear, and the first gear passes through meshing The power is transmitted to the first rack. At this time, the rotary motion is converted into linear reciprocating motion again through the first gear and the first rack. The first rack drives the sucker rod to reciprocate to complete the oil pumping work of the driven oil well.

Compared with the prior art, the utility model makes full use of the crank connecting rod mechanism to convert the unidirectional rotary motion into a linear reciprocating motion; at the same time, it uses a rack and pinion mechanism to convert the linear reciprocating motion into a unidirectional rotary motion; its structure is simple , small size, easy operation, low energy consumption, low maintenance cost and long service life.
