Embodiment Construction
[0012] Now in conjunction with accompanying drawing and specific embodiment the present invention is further described as follows:
[0013] As can be seen from the accompanying drawings, the rotary base (1) of the present invention is achieved through the following technical proposals. There are four sets of rollers (2) on both sides of the double well pumping unit base (1). When the rotary pumping unit First fix the center of rotation, loosen the fixing bolts of the base (1), support the rollers (2), the four sets of rollers (2) roll on the ring track on the cement foundation to rotate the double well pumping unit 180 degrees, turn the The two ends of the double well pumping unit are interchangeable.
[0014] As can be seen from the accompanying drawings, the support arm (4) with the runner (5) of the present invention is realized through the following technical proposals, on the double well pumping unit base (1) near the crank (3) side A support arm (4) has a runner (5) on ...
