Embodiment Construction
[0024] see figure 1 , Fig. 2, Fig. 3, pendulum balance intelligent control pumping unit of the present invention has base 14, frame 7, motor 2, reversing mechanism and balance mechanism. Wherein: the frame 7 is a cantilever structure protruding from the top, and the extension end is equipped with a rope pulley 8 to maintain the distance between the main body of the frame 7 and the wellhead 10, which is convenient for workover operations and downhole fault handling. The reversing mechanism is arranged on one side of the frame 7 and is composed of active and passive reversing wheels 4 and 5. Both the active and passive reversing wheels 4 and 5 are provided with forward and reverse spiral rope grooves to prevent the pulling of the rope. Damaged by extrusion friction during winding. Active reversing wheel 4 is contained in the bottom of frame 7, and is connected with motor 2 by belt transmission part 3, and passive reversing wheel 5 is contained in the middle part of frame 7, and...
