Embodiment Construction
[0032] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this application. Rather, they are merely examples of approaches consistent with aspects of the application as recited in the appended claims.
[0033] It should be noted that the pumping unit is a large and heavy oilfield mining machine, the bottom of which is the base of the pumping unit, and below the base of the pumping unit is a foundation base that is fixed relative to the ground, and the base base can be made of cement It can also be poured by concrete. There are embedded parts in the foundation base, and the embedded parts can be embedded cha...

The application provides a deflection adjustment device for a pumping unit, which belongs to the technical field of oil field development. The device includes a first base plate, positioning bolts, nuts, a stressed back plate, a support plate and a centralizing ring, wherein: the first base plate is provided with a first through hole, and the positioning bolts are connected from below the first base plate. passing through the first through hole and connecting with the nut above the first bottom plate, the stressed back plate and the support plate are arranged above the first bottom plate and perpendicular to the first bottom plate The bottom plate, the support plate is provided with a second through hole, the centralizing ring includes a ring and a first cylinder, the ring is connected to one end of the first cylinder, and the first cylinder passes through pass through the second through hole and be flexibly connected with the second through hole. By adopting the device, when adjusting the deflection of the pumping unit, it can be ensured that the force direction of the jack is perpendicular to the side of the base of the pumping unit that the jack contacts, so that the jack is not easy to fly out and the safety risk is reduced.
Description
technical field [0001] The embodiment of the present application relates to the technical field of oil field development, and in particular to a deflection adjustment device for a pumping unit. Background technique [0002] The pumping unit is a commonly used equipment in the process of oilfield development. It is large in size and heavy in weight, so there are various methods of adjusting the deviation of the pumping unit. The base deviation adjustment is a commonly used method of adjusting the deviation of the pumping unit. [0003] The base base is made of cement or concrete, and is located between the base of the pumping unit and the ground. In related technologies, when adjusting the base of the pumping unit, the base base is fixed. In the embedded part of the foundation base, use a jack to jack up the pumping unit, and then move the jacked up pumping unit to move on the foundation base, so as to achieve deviation adjustment. [0004] In the above-mentioned technology,...
