Problems solved by technology

[0002] The biggest advantage of the conventional beam pumping unit lies in its simple structure, easy manufacture, and convenient installation. However, its technical defects are also very obvious: poor balance effect, large load moment fluctuation, low system efficiency, large power loss, stroke and It is inconvenient to adjust the number of strokes, and the four-bar linkage mechanism has relatively many active points, which is prone to failure, causing shutdown and affecting production, etc.
People have carried out a large amount of research and exploration for this reason, and known most of this type of innovative technologies, although solved one or several technical problems that conventional pumping units exist, it tends to highlight other problems such as structure at the same time. The root cause of new problems such as complexity, increased manufacturing costs, and reduced operational reliability is that innovators mostly start from a single perspective such as mechanical structure or electrical control and the application of new materials, and seldom from the overall perspective of mechatronics , conduct comprehensive and systematic in-depth research on many problems that need to be solved urgently in the pumping unit

Embodiment 1

[0039] Embodiment one: as attached figure 1 As shown, when the swing arm assembly 13 is stacked with the tail beam 4 that is tilted downward, the arc segment-shaped suspension weight body 11 can completely replace the counterweight body 10 in the tail beam balance weight device. The motor 6 with forward and reverse functions can use the single-arm structure when the lifting body 11 is reciprocatingly driven according to the operating parameters set in advance by the intelligent control box 5, and the single-arm structure can greatly save The manufacturing cost of the equipment has solved the difficult problem that the conventional pumping unit will run into the scissor difference unavoidably when using double crank operation on both sides of the frame 7.

Embodiment 2

[0040] Embodiment two: as attached figure 2 As shown, the tail beam balance weight device of the equipment is tilted downward, and the suspension pendulum device is symmetrically arranged on the left and right sides of the frame 7 through the connecting piece. 4 are connected, and the lower end of the swing arm assembly 13 and the swing arm link assembly 15 are connected to each other, thereby forming a stable triangular beam structure together with the beam 3 and the tail beam 4, and the arc-shaped suspension connected to the swing arm mechanism Heavy body 11 is driven by the motor 6 with forward and reverse functions to drive the beam to swing back and forth.

Embodiment 3

[0041] Embodiment three: as attached figure 2 and image 3 As shown, there are two points of difference with Embodiment 2: one is that the motor used for driving is different, and what Embodiment 2 adopts is a rotating motor, and when it drives the arc-shaped hoisting body 11, it must use wheel surface friction or engagement The transmission mode, and what embodiment 3 adopts is linear motor, when driving hoisting weight 11, what used is the magnetic field effect. The second is that the shape of the tail beam balance weight device on the lower side of the equipment is different. The second embodiment adopts the lower folding beam structure, while the third embodiment adopts the lower hanging beam structure.
