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...

Abstract

The invention provides a deviation adjusting device of a pumping unit, and belongs to the technical field of oil field development. The deviation adjusting device comprises a first bottom plate, a positioning bolt, a nut, a stressed back plate, a supporting plate and a centralizing ring, wherein a first through hole is formed in the first bottom plate, the positioning bolt penetrates through the first through hole from the bottom of the first bottom plate and is connected with the nut located above the first bottom plate, the stress back plate and the supporting plate are arranged above the first bottom plate and are perpendicular to the first bottom plate, a second through hole is formed in the supporting plate, the centralizing ring comprises a circular ring and a first column body, thecircular ring is connected with one end of the first column body, and the first column body penetrates through the second through hole and is movably connected with the second through hole. By the adoption of the deviation adjusting device, when the pumping unit is subjected to deviation adjustment, the stress direction of the jack is ensured to be perpendicular to the side surface of the oil pumping unit base in contact with the jack, 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,...
