Description

Technical Field

[0001] This utility model relates to the field of oil pumping unit technology, and in particular to a vibration damping base structure for an oil pumping unit that can be quickly disassembled and assembled. Background Technology

[0002] During oil extraction operations, the periodic operation of the motor, crank connecting rod mechanism, and downhole pump generates continuous vibrations. These vibrations are transmitted to the foundation structure through the machine body, causing not only overall machine shaking and noise, but also long-term effects on key components, leading to loosening of connections, structural fatigue, or even premature failure, which seriously affects the operational stability and service life of the pumping unit.

[0003] Traditionally, a concrete platform is often installed under the pumping unit as a foundation. While this provides some stability, it lacks active vibration damping capabilities. Vibration energy is still transmitted to the ground through the rigid foundation, which can easily cause foundation settlement or loosening of the surrounding strata. In addition, concrete platforms are bulky, have long construction periods, are immovable, and are difficult to adapt to different well site terrain conditions. Furthermore, they cannot be reused when equipment is relocated or maintained, resulting in poor economic efficiency and flexibility.

[0004] While existing vibration damping structures with energy dissipation capabilities can theoretically effectively absorb and disperse vibration energy, their disassembly and maintenance are often difficult in practical field applications. These structures are typically integrated designs that cannot be disassembled, or require specialized tools and personnel for removal and replacement. In the harsh working environment of oil fields, the complex disassembly process not only increases maintenance time and labor costs but may also lead to component damage or decreased vibration damping performance due to improper operation, thus limiting the widespread application of this type of vibration damping structure. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a quick-disassembly and assembly vibration damping base structure for oil pumping units. Its structure is simple and reasonably designed. The base and support are connected by a connecting rod and a clamping block, which facilitates disassembly and assembly. When the vibration of the oil pumping unit forces the first moving block and the second moving block to displace on the fixed rod, the displacement of the first moving block and the second moving block compresses the first spring and the second spring, and at the same time drives the V-shaped elastic frame to undergo torsional deformation, thereby dissipating the vibration energy and achieving vibration reduction.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a quick-disassembly and detachable vibration damping base structure for an oil pumping unit. The oil pumping unit includes a base, characterized in that: the bottom of the base has a groove, and a fixing rod is connected inside the groove. The left and right sides of the fixing rod are connected to the inner wall of the base. A first spring, a second spring, a first moving block, and a second moving block are sleeved on the fixing rod. The two ends of the first spring are respectively in contact with the first moving block and the first fixing block. The two ends of the second spring are respectively in contact with the second moving block and the second fixing block. The first fixing block and the second fixing block are fixedly connected to the fixing rod. The system also includes a V-shaped elastic frame. One end of the V-shaped elastic frame is connected to the first moving block, and the other end of the V-shaped elastic frame is connected to the second moving block. The V-shaped elastic frame is mounted on a support plate via a mounting seat.

[0007] The above-mentioned quick-assembly and disassembly pumping unit vibration damping base structure is characterized in that: the V-shaped elastic frame includes a torsion spring, the first arm of the torsion spring is connected to the first moving block, the second arm of the torsion spring is connected to the second moving block, and the torsion spring is sleeved on the mounting base; the mounting base is also provided with a first damper and a second damper, the top of the first damper is fixedly connected to the first arm of the torsion spring, and the top of the second damper is fixedly connected to the second arm of the torsion spring.

[0008] The above-mentioned quick-disassembly and detachable pumping unit vibration damping base structure is characterized in that: a first spring, a second spring, a first moving block, a second moving block, a first fixed block, a second fixed block, and a V-shaped elastic frame form a minimum vibration damping unit, and the number of minimum vibration damping units is multiple.

[0009] The above-mentioned quick-disassembly and detachable pumping unit vibration damping base structure is characterized in that: the first spring and the second spring are made of elastic bellows.

[0010] The above-mentioned quick-disassembly and detachable pumping unit vibration damping base structure is characterized in that: the first damper and the second damper are bidirectional hydraulic dampers.

[0011] The above-mentioned quick-assembly and disassembly pumping unit vibration damping base structure is characterized in that: mounting plates are fixedly connected to both sides of the support plate, and multiple adjustment holes are opened on the mounting plates along the length direction; connecting holes are opened on both sides of the base, and connecting rods pass through the adjustment holes and connecting holes and are fastened to the clamping blocks.

[0014] The above-mentioned quick-disassembly and detachable pumping unit vibration damping base structure is characterized in that: a donkey head is fixedly connected to the right side of the walking beam, and a suspension rope device is provided on the right side of the donkey head.

[0015] The above-mentioned quick-disassembly and detachable pumping unit vibration damping base structure is characterized in that: a driving component is fixedly connected to the top left side of the base, and the output end of the driving component is provided with a crank.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, when the oil pumping unit is working, it generates vibration. The vibration is transmitted to the base through the mounting point of the crossbeam and the drive component. At this time, it is transmitted to the moving block through the base, driving the first moving block and the second moving block to move. The displacement of the first moving block and the second moving block compresses the first spring and the second spring, dissipating the vibration energy.

[0018] 2. In this utility model, when the pumping unit is working, it generates vibration. The vibration is transmitted to the base through the mounting points of the crossbeam and the drive component. At this time, it is transmitted to the moving block through the base, driving the first moving block and the second moving block to move. The displacement of the first moving block and the second moving block drives the V-shaped elastic frame to undergo torsional deformation. The first damper and the second damper directly consume the kinetic energy generated by the V-shaped elastic frame, rapidly dissipating the vibration energy and achieving efficient vibration reduction.

[0019] 3. In this utility model, the base and the support are connected by a connecting rod and a clamping block, which facilitates disassembly and assembly.

[0020] In summary, this utility model has a simple structure and reasonable design. The base and support are connected by a connecting rod and a clamping block, which facilitates disassembly and assembly. When the vibration of the pumping unit forces the first and second moving blocks to move on the fixed rod, the displacement of the first and second moving blocks compresses the first and second springs, and at the same time drives the V-shaped elastic frame to undergo torsional deformation, thereby dissipating the vibration energy and achieving vibration reduction.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see the appendix Figure 1 To be continued Figure 5 The present invention includes a base 1, characterized in that: the bottom of the base 1 has a groove, and a fixing rod 201 is connected in the groove. The left and right sides of the fixing rod 201 are connected to the inner wall of the base 1. A first spring 2021, a second spring 2022, a first moving block 2031, and a second moving block 2032 are sleeved on the fixing rod 201. The two ends of the first spring 2021 are respectively in contact with the first moving block 2031 and the first fixing block 2011. The two ends of the second spring 2022 are respectively in contact with the second moving block 2032 and the second fixing block 2012. The first fixing block 2011 and the second fixing block 2012 are fixedly connected to the fixing rod 201. The invention also includes a V-shaped elastic frame 204. One end of the V-shaped elastic frame 204 is connected to the first moving block 2031, and the other end of the V-shaped elastic frame 204 is connected to the second moving block 2032. The V-shaped elastic frame 204 is mounted on a support plate 206 through a mounting base 205.

[0035] It should be noted that the inner wall of the base 1 is also provided with a guide limiting groove that is compatible with the fixing rod 201, and a buffer pad is provided in the guide limiting groove.

[0036] In one possible embodiment, the cushioning pad is a rubber pad.

[0037] In one possible embodiment, the V-shaped elastic frame 204 includes a torsion spring, the first arm of which is connected to the first moving block 2031, and the second arm of which is connected to the second moving block 2032. The torsion spring is sleeved on the mounting base 205. The mounting base 205 is also provided with a first damper 2091 and a second damper 2092. The top of the first damper 2091 is fixedly connected to the first arm of the torsion spring, and the top of the second damper 2092 is fixedly connected to the second arm of the torsion spring.

[0038] It should be noted that the first arm of the torsion spring is hinged to the first moving block 2031, and the second arm of the torsion spring is hinged to the second moving block 2032. The hinge offers advantages of high reliability and low wear, making it suitable for the oscillation of the torsion spring. The torsion spring is a V-type torsion spring, which includes two symmetrical arms connected to form a "V" shape.

[0039] The V-shaped elastic frame not only serves as a transmission mechanism, transferring the vibration energy borne by the first and second moving blocks to the first and second dampers, causing them to actuate and dissipate energy; at the same time, since the V-shaped elastic frame includes a torsion spring, the torsion spring also dissipates some vibration energy during repeated torsional deformation. Therefore, the V-shaped elastic frame improves the overall vibration reduction efficiency.

[0040] In actual use, multiple minimum vibration damping units are first installed on the fixed rod. Then, the fixed rod 201 is placed at the designated position. Since the pumping unit itself cannot move, its transportation and installation mainly rely on hoisting and truck transport. The pumping unit is hoisted to the designated position, and the fixed rod 201 engages with the base along the guide limiting groove. Then, the support plate 206 is connected to the base via the connecting rod 2072 and the clamping block. Adjusting the adjusting hole into which the connecting rod 2072 is inserted changes the height of the support plate 206, making the bottom end of the support plate 206 flush with the bottom end of the base.

[0041] When the pumping unit vibrates during operation, the vibration is transmitted to the base through the crossbeam and the mounting point of the drive component. The vibration of the base 1 causes the fixed rod 201 to vibrate, and the fixed rod 201 causes the first moving block 2031 and the second moving block 2032 to move. The displacement of the first moving block 2031 and the second moving block 2032 compresses the first spring 2021 and the second spring 2022 respectively. The compression and recovery of the first spring 2021 and the second spring 2022 are used to dissipate energy.

[0042] Simultaneously, the displacement of the first moving block 2031 and the second moving block 2032 drives the V-shaped elastic frame 204 to undergo torsional deformation. The top of the first damper 2091 is fixedly connected to the first arm of the torsion spring of the V-shaped elastic frame 204, and the top of the second damper 2092 is fixedly connected to the second arm of the torsion spring of the V-shaped elastic frame 204. The first damper 2091 and the second damper 2092 directly consume the kinetic energy generated by the V-shaped elastic frame 204, dissipating the vibration energy and achieving vibration reduction. This is also the most important energy dissipation method.

[0043] In this embodiment, the first spring 2021, the second spring 2022, the first moving block 2031, the second moving block 2032, the first fixed block 2011, the second fixed block 2012, and the V-shaped elastic frame 204 constitute the minimum vibration damping unit, and there are multiple minimum vibration damping units.

[0044] like Figure 2 As shown, in one possible embodiment, the minimum number of vibration damping units is 3.

[0045] In this embodiment, the first spring 2021 and the second spring 2022 are made of elastic bellows. The elastic bellows itself can act as a spring and also provide material damping, thus dissipating energy.

[0046] In this embodiment, the first damper 2091 and the second damper 2092 are bidirectional hydraulic dampers. The bidirectional hydraulic damper has bidirectional damping characteristics of compression and tension, converting kinetic energy into heat energy, ensuring that vibration energy is effectively dissipated during the compression and rebound stages of the V-shaped elastic frame 204.

[0047] In this embodiment, mounting plates 2071 are fixedly connected to both sides of the support plate 206. Multiple adjustment holes are provided on the mounting plate 2071 along the length direction. Connection holes are provided on both sides of the base 1. The connecting rod 2072 passes through the adjustment holes and the connection holes and is fastened to the clamping block.

[0048] In one possible embodiment, the connecting rod 2072 is a screw and the clamping block is a nut.

[0049] The support plate 206 is connected to the base via the connecting rod 2072 and the clamping block. By adjusting the adjustment hole into which the connecting rod 2072 is inserted, the height of the support plate 206 can be changed to adapt to slight undulations in the ground, so that the bottom end of the support plate 206 and the bottom end of the base are flush and in contact with the ground.

[0050] In this embodiment, a platform 5 is fixedly connected to the top of the crossbeam 4, and a walking beam 6 is connected to the top of the crossbeam 4. A donkey head 7 is fixedly connected to the right side of the walking beam 6, and a suspension rope device is provided on the right side of the donkey head 7. A driving component 8 is fixedly connected to the top left side of the base 1, and a crank is provided at the output end of the driving component 8.

[0051] Specifically, a platform 5 is fixedly connected to the top of the crossbeam 4. The platform 5 provides a platform for workers to stand on to facilitate the maintenance of the upper components of the walking beam 6. The walking beam 6 is connected to the top of the crossbeam 4. The walking beam 6 is used to transmit power to the drive component 8 and drive the donkey head 7 to perform reciprocating motion. The donkey head 7 is fixedly connected to the right side of the walking beam 6. The donkey head 7 changes the force direction of the suspension device through an arc structure to ensure the stable operation of the sucker rod. The suspension device is provided on the right side of the donkey head 7. The suspension device is used to connect the donkey head 7 to the sucker rod and to buffer the impact force during the oil extraction process to protect the sucker rod. The drive component 8 is fixedly connected to the top left side of the base 1. The drive component 8 provides power to the oil extraction unit and drives the crank to rotate. The output end of the drive component 8 is provided with a crank. The crank converts the rotational motion of the drive component 8 into reciprocating motion to drive the walking beam 6 to rotate.

[0052] Working principle: First, multiple minimum vibration damping units are installed on the fixed rod. Then, the fixed rod 201 is placed at the designated position. The pumping unit itself cannot move; its transportation and installation mainly rely on hoisting and truck transport. The pumping unit is hoisted to the designated position, and the fixed rod 201 engages with the base along the guide limiting groove. Then, the support plate 206 is connected to the base through the connecting rod 2072 and the clamping block. Adjusting the adjustment hole into which the connecting rod 2072 is inserted changes the height of the support plate 206 to adapt to slight ground undulations, ensuring that the bottom end of the support plate 206 is flush with the bottom end of the base and in contact with the ground.

[0053] When the pumping unit vibrates during operation, the vibration is transmitted to the base through the crossbeam and the mounting point of the drive component. The vibration of the base 1 causes the fixed rod 201 to vibrate, and the fixed rod 201 causes the first moving block 2031 and the second moving block 2032 to move. The displacement of the first moving block 2031 and the second moving block 2032 compresses the first spring 2021 and the second spring 2022 respectively. The compression and recovery of the first spring 2021 and the second spring 2022 are used to dissipate energy.

[0054] Simultaneously, the displacement of the first moving block 2031 and the second moving block 2032 drives the V-shaped elastic frame 204 to undergo torsional deformation. The top of the first damper 2091 is fixedly connected to the first arm of the torsion spring of the V-shaped elastic frame 204, and the top of the second damper 2092 is fixedly connected to the second arm of the torsion spring of the V-shaped elastic frame 204. The first damper 2091 and the second damper 2092 directly consume the kinetic energy generated by the V-shaped elastic frame 204, dissipate the vibration energy, and achieve vibration reduction.

[0055] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
