[0002] In the field of oil extraction, pumping units, as key mechanical equipment, play a vital role. With the continuous growth of global energy demand and the continuous advancement of oil extraction technology, higher and higher requirements are placed on the performance, efficiency and reliability of pumping units. In order to meet these requirements, oilfield pumping units have undergone an evolution from simple to complex, from inefficient to efficient. With the continuous development of domestic oil fields, especially most of the oil fields in the east have entered the middle and late stages of water injection development, the oil fields have an increasingly urgent need for the extraction of deep well oil, high water content oil and heavy oil.

The present invention increases the torque of the motor by multiples by adding a set of reduction gear sets to the driving motor, so that it can drive a counterweight weighing several tons. The motor is equipped with an automatic control system, which detects the load change of the downhole load in real time through the pressure sensor, automatically matches the motor power, and keeps the balance belt at both ends at all times, thereby realizing the adjustment of the counterweight of the tower-type oil pump, avoiding the previous mode of manually operating the lifting equipment to operate when adjusting the counterweight, simplifying the construction process and reducing the construction cost.

[0040] The working principle of the present invention is as follows: firstly, a hydraulic cylinder 3 is set, and the output end of the hydraulic cylinder 3 moves upward or downward with the lifting block 4, and the lifting block 4 is adjusted to a suitable height with the bidirectional motor 501, the transmission shaft 502, the cross block 500, the screw rod 505, the crank rod 506, the fixed block 507, the cross beam 508, the limit plate 509, and the connecting block 510; A transmission shaft 502 is provided, and the output end of the transmission shaft 502 rotates with the cross block 500 deviating from the center of the circle. The cross block 500 rotates and then drives the screw rod 505, the moving block 503, the crank rod 506, the fixed block 507, the cross beam 508, the limit plate 509, and the connecting block 510 to swing up and down at a certain speed. The connecting block 510 drives the oil beam 600 to swing, and the oil beam 600 drives the threaded column 602, the sliding block 603, and the connecting rod 604 to swing up and down along the positioning block 12 through the extension block 605. One side of the connecting rod 604 moves the sucker rod 10 up and down, and the sucker rod 10 moves the positioning column 906, the annular plate 904, and the sucker plug 900 up and down. The sucker plug 900 moves up and down to generate suction, so that the oil in the soil moves upward along the oil pipeline 8. The oil pushes the ball 902 so that the ball 902 squeezes the spring 903, and then the oil enters from the oil inlet hole 901 and is discharged from the oil outlet hole 905, and then moves upward. Finally, the oil is sucked into the collection box through the guide pipe 11; When it is necessary to change the swing speed, an adjustment motor 504 is set, and the output end of the adjustment motor 504 rotates with the screw rod 505. The screw rod 505 rotates to make the moving block 503 move upward or downward with the crank rod 506 along the screw rod 505 and the slide groove to adjust away from the center of the cross block 500. When the moving block 503 deviates from the center of the cross block 500 with the crank rod 506, the fixed block 507, the cross beam 508, and the limit plate 509, the cross block 500 rotates with the screw rod 505, the moving block 503, the crank rod 506, the fixed block 507, the cross beam 508, the limit plate 509, and the connecting block 510 to increase or decrease the amplitude of the up and down swing, so that the swing amplitude can be adjusted while swinging, thereby controlling the speed of oil pumping, and at the same time, it can play a certain degree of oil pumping increase or decrease effect; An adjusting motor 601 is provided, and the output end of the adjusting motor 601 rotates along the middle part of the oil beam 600 with the threaded column 602. The rotation of the threaded column 602 causes the sliding block 603 to move the connecting rod 604 forward or backward along the threaded column 602 and the slide groove to adjust the position, so that the overall moving length between the connecting rod 604 and the sucker rod 10 increases or decreases, thereby controlling the overall moving length of the sucker rod 10 with the positioning column 906, the positioning column 906, and the sucker plug 900 in the oil pipeline 8, thereby achieving the effect of increasing or decreasing the pumping speed of the pumping unit, and at the same time, it can increase or decrease the speed to a certain extent.

[0041] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
