Description

Technical Field

[0001] This utility model relates to the field of oil pumping unit installation technology, specifically to an oil pumping unit foundation. Background Technology

[0002] In oilfield development, pumping units are the main surface equipment for pumping oil from wells. Pumping units are typically built on reinforced concrete blocks as their foundation, with a leveled subgrade of rammed earth beneath. The pumping unit's base rests on this foundation, and the base and foundation are secured together with fastening bolts to ensure stable operation of the pumping unit while maintaining a relatively level surface.

[0003] Due to the long-term heavy-load operation of the pumping unit and the continuous erosion of the foundation by rainwater, the foundation may subside, resulting in an uneven foundation and affecting the normal operation of the pumping unit. The conventional adjustment method is to shut down the pumping unit and remove the load, then use a crane to lift the foundation, re-level the foundation, and then reinstall the pumping unit foundation and pumping unit in sequence. The workload is equivalent to reinstalling the pumping unit.

[0004] Therefore, some designs incorporate pre-installed lifting devices in the pumping unit base, such as the utility model patent with authorization announcement number CN211550938U, which discloses a pumping unit base adjustment device. This device includes a motor and a threaded lifting rod connected to the motor drive. The threaded lifting rod is arranged around the adjustment device, and by adjusting the lifting height of the threaded lifting rod, the tilt angle of the pumping unit base can be adjusted. However, the lifting device in the above technical solution is fixed between the pumping unit base and the pumping unit foundation, and can only adjust the pumping unit base, not the pumping unit foundation. For example, when the pumping unit foundation sinks, it cannot be adjusted, causing it to sink deeper.

[0005] To address the aforementioned technical problem of the inability to adjust the pumping unit foundation, patent document CN220468922U discloses a pumping unit foundation lifting device. This device utilizes a force-applying component to provide an upward torque to the pumping unit foundation lifting mechanism, thereby providing an upward lifting torque to the pumping unit foundation. A lifting structure facilitates the coordination between the lifting mechanism and the pumping unit foundation, ensuring smooth torque transmission. Furthermore, a top support structure allows for control during lifting, preventing overturning. In other words, it provides an upward torque to the pumping unit foundation from the side, thus solving the problem of the inability to lift the pumping unit foundation in existing technologies. However, when lifting the pumping unit foundation, the threaded section needs to connect to the screw head, and the connecting hook needs to engage the lifting ring. When using a jack to lift the horizontal and vertical plates, the contact area between the bare rod section and the lifting ring and the foundation is small, resulting in high stress on the foundation at these locations, making them prone to damage. This device can lift the foundation, but it cannot effectively solve the fundamental problem of the foundation being prone to settlement. Utility Model Content

[0006] The main objective of this invention is to provide a pumping unit foundation that can increase the contact area with the ground and reduce the probability of settlement. After settlement, this foundation can be easily lifted for subsequent ground leveling.

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0008] A prefabricated oil pump foundation includes a foundation body, with the oil pump body fixed to the upper end of the foundation body. A ring is provided on the outer side of the foundation body and is embedded and fixed within the foundation body. The shape of the ring is adapted to the shape of the foundation body. The ring includes a vertical ring, with an upper ring fixed to the outer side of the upper end of the vertical ring and a lower ring fixed to the outer side of the lower end of the vertical ring. The width of the upper ring is greater than the width of the lower ring. The vertical ring is fixedly connected to a steel cage inside the foundation body. A blocking member is detachably and fixedly connected to all four sides of the outer side of the vertical ring. The blocking member includes a support plate. Mounting seats are detachably and fixedly connected to the outer sides of the vertical ring on both the upper and lower sides of the support plate. The support plate is inserted between two adjacent mounting seats.

[0009] Specifically, the vertical ring, upper ring, and lower ring are integrally formed.

[0010] Specifically, multiple inner rods are fixed inside the vertical ring, and the inner rods are fixedly connected to the steel cage inside the foundation body.

[0011] Specifically, the outer edge of the upper ring is connected to the upper end of the base body through a slope transition, with the upper end of the slope inclined towards the center of the base body, and the outer edge of the lower ring is connected to the lower end of the base body through a vertical transition.

[0012] Specifically, a plurality of second stiffening plates are fixed to the upper end of the support plate.

[0013] Specifically, the mounting base includes a vertical plate, on which a flat plate is fixed. A support plate is located between the upper and lower flat plates, and the support plate contacts the flat plate. The vertical plate and the vertical ring are detachably and fixedly connected.

[0014] Specifically, the flat plate and the upright plate are flush with the end facing the support plate, the support plate is located between two adjacent upright plates, and the support plate is tightly against the outside of the upright ring.

[0015] Specifically, the flat plate and the upright plate are fixedly connected by a first stiffening plate.

[0016] Specifically, a screw is fixed on the vertical ring, the screw passes through the opening in the vertical plate, and a nut is threaded onto the screw. After the nut is pressed against the vertical plate, the mounting base is fixed on the vertical ring.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. By integrally molding the vertical ring, upper ring, and lower ring and fixing them to the reinforcing cage, a three-dimensional support frame is formed, which significantly improves the structural rigidity of the foundation, disperses load pressure, and reduces local stress concentration. The support plate extends horizontally, significantly increasing the contact area between the foundation and the ground, reducing the pressure per unit area, and inhibiting settlement from the source.

[0019] 2. The mounting base and support plate are detachably connected, allowing for quick removal of obstructions in the settlement area. Jacks can be used to directly lift the upper ring of the foundation body, eliminating the need for hoisting equipment or complete disassembly, significantly reducing the complexity of adjustment operations. The inclined transition of the upper ring enhances its load-bearing and deformation resistance, while the vertical surface of the lower ring reduces the upward resistance of the foundation body, ensuring a smooth and efficient lifting process.

[0020] 3. The first and second stiffening plates form a multi-directional support network to prevent deformation of the mounting base and bending of the support plate, thus extending the service life of the components. The inner rod on the inner side of the vertical ring is welded to the reinforcing cage, deeply integrating the ring with the foundation body to prevent the ring from becoming dislodged or loosened due to external impact.

[0021] 4. The foundation body is prefabricated, and the ring and blocking components use standardized parts, which facilitates mass production and rapid on-site installation, shortening the construction cycle. The design of the support plate in direct contact with the ground allows for readjustment of the support plate height after local foundation repairs, ensuring the long-term levelness of the foundation body.

[0022] 5. The support plate is embedded between the upper and lower mounting plates and is laterally limited by the tight abutment of the vertical ring to prevent the foundation body from shifting or overturning during lifting or operation, thus improving safety redundancy.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1: Refer to Figures 1-4 As shown, a pumping unit foundation is prefabricated. It includes a foundation body 1, and a pumping unit body 2 is fixed to the upper end of the foundation body 1.

[0030] A ring is provided on the outside of the base body 1. The ring is embedded and fixed inside the base body 1, and the shape of the ring is adapted to the shape of the base body 1.

[0031] The ring component includes a vertical ring 3, an upper ring 10 fixed to the outer side of the upper end of the vertical ring 3, and a lower ring 4 fixed to the outer side of the lower end of the vertical ring 3. The vertical ring 3, the upper ring 10 and the lower ring 4 are integrally formed.

[0032] The width of the upper ring 10 is greater than that of the lower ring 4. The outer edge of the upper ring 10 is connected to the upper end of the base body 1 by a sloped transition, and the upper end of the sloped transition is inclined towards the center of the base body 1. The outer edge of the lower ring 4 is connected to the lower end of the base body 1 by a vertical transition.

[0033] The vertical ring 3 is fixedly connected to the reinforcing cage 6 inside the foundation body 1. Specifically, multiple inner rods 5 are fixed inside the vertical ring 3, and the inner rods 5 are fixedly connected to the reinforcing cage 6 inside the foundation body 1.

[0034] The outer four sides of the vertical ring 3 are detachably fixed with blocking parts.

[0035] The blocking component includes a support plate 8, with multiple second stiffening plates 9 fixed to the upper end of the support plate 8. Mounting seats 7 are detachably and fixedly connected to the outer sides of the vertical rings 3 on both the upper and lower sides of the support plate 8, and the support plate 8 is inserted between two adjacent mounting seats 7.

[0036] The mounting base 7 includes a vertical plate 701, on which a flat plate 702 is fixed. The flat plate 702 and the vertical plate 701 are fixedly connected by a first stiffener 703. A support plate 8 is located between the upper flat plate 702 and the lower flat plate 702, and the support plate 8 is in contact with the flat plate 702.

[0037] The upright plate 701 and the upright ring 3 are detachably and fixedly connected. Specifically, a screw is fixed on the upright ring 3, the screw passes through the opening on the upright plate 701, and a nut is threaded onto the screw. After the nut is pressed tightly against the upright plate 701, the mounting base 7 is fixed on the upright ring 3.

[0038] Multiple inner rods 5 inside the vertical ring 3 are fixedly connected to the steel cage 6 inside the foundation body 1. After the foundation body 1 is cast and formed, it can improve the structural strength of the foundation body 1.

[0039] The foundation body 1 is placed on the foundation, and the lower end of the support plate 8 is in contact with the ground. By setting the support plate 8, the support area of ​​the foundation body 1 can be increased, and the second stiffening plate 9 can improve the structural strength of the support plate 8.

[0040] When one side of the foundation body 1 settles, the nuts on the settled side of the foundation body 1 are removed, and the mounting base 7 on the settled side of the foundation body 1 is separated from the foundation body 1. Then, the jack is placed on the support plate 8 on the settled side of the foundation body 1, so that the lifting end of the jack contacts the lower end of the upper ring 10 on the settled side of the foundation body 1. Since the ring width of the upper ring 10 is greater than the ring width of the lower ring 4, the upper ring 10 can serve as the force-bearing point of the foundation body 1 when the foundation body 1 is lifted by the jack.

[0041] Since the outer edge of the upper ring 10 is connected to the upper end of the base body 1 through a slope transition, and the upper end of the slope is inclined towards the center of the base body 1, the bearing capacity of the upper ring 10 can be improved when the base body 1 is lifted, and the deformation of the upper ring 10 can be avoided when the base body 1 is lifted.

[0042] The outer edge of the lower ring 4 is connected to the lower end of the foundation body 1 through a vertical transition surface. When the foundation body 1 is lifted by jacks, the resistance of the soil layer to the foundation body 1 when the foundation body 1 moves upward can be reduced.

[0043] After the foundation body 1 on the settlement side is lifted, the foundation is leveled. After the foundation leveling is completed, the ground outside the foundation body 1 is leveled, the disassembled mounting base 7 is reconnected to the vertical ring 3, and then the support plate 8 is installed, so that the lower end of the support plate 8 contacts the ground outside the foundation body 1.

[0044] Example 2: Based on Example 1, referring to... Figure 3 and Figure 4 As shown, the flat plate 702 and the upright plate 701 are flush with one end facing the support plate 8. The support plate 8 is located between two adjacent upright plates 701, and the support plate 8 is close to the outside of the upright ring 3.

[0045] Since the flat plate 702 and the vertical plate 701 are flush with the end facing the support plate 8, and the support plate 8 is located between the two adjacent vertical plates 701, the contact area between the support plate 8 and the mounting base 7 can be increased, which improves the stability of the connection between the support plate 8 and the mounting base 7 and avoids deformation of the mounting base 7 due to local stress.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
