Technical Field
[0001] This utility model relates to the field of oil extraction equipment technology, and in particular to a shock absorption system for an oil extraction pumping unit. Background Technology
[0002] In oil extraction, pumping units are the main lifting equipment in rod-type pumping systems. However, during operation, the pumping unit generates significant vibrations due to the different loads during the up and down strokes. Long-term accumulation of this vibration can damage internal components such as gears and bearings, reducing their lifespan and increasing equipment maintenance costs and downtime.
[0003] The inventors believe that the following defects often exist: when the oil pumping unit is running, due to the different loads of the upper and lower strokes, significant vibration will be generated. The vibration will damage the internal parts and shorten the service life of the oil pumping unit. Therefore, a vibration reduction system for oil pumping units in oil extraction is proposed to address the above problems. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as vibration during the operation of oil pumping units and the damage caused by the vibration to internal parts, and to propose a vibration reduction system for oil pumping units in oil extraction.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a shock absorption system for an oil extraction pumping unit, comprising a pumping unit body, a cover plate installed on the surface of the pumping unit body, a shock absorption device provided on the surface of the pumping unit body, the shock absorption device comprising four irregularly shaped frames, the four irregularly shaped frames being slidably connected to the surface of the pumping unit body, the four irregularly shaped frames being grouped in pairs, a fixed frame being slidably connected to the surface of each group of irregularly shaped frames, a base plate being fixedly connected to one side of two of the fixed frames, a sliding plate being slidably connected inside the irregularly shaped frame, two springs being fixedly connected to one side of the sliding plate, and one end of the springs being fixedly connected to the irregularly shaped frame.
[0006] The effect achieved by the above-mentioned components is as follows: by setting up a shock-absorbing device, the vibration of the pumping unit body is reduced, avoiding the pumping unit body from being subjected to its own or external forces during operation, which would cause a certain degree of vibration to the pumping unit body, damage to internal parts, and shorten the service life of the pumping unit, thus improving the practicality of the device.
[0007] Preferably, the irregular frame has a bolt inserted into its internal thread, and the arc surface of the bolt is threadedly connected to the fixing frame.
[0008] The aforementioned components achieve the following effects: they can be adapted to different sizes of pumping unit bodies, the position of the irregularly shaped frame can be easily adjusted to adapt to different sizes of pumping unit bodies, and the versatility and applicability of the device can be enhanced.
[0009] Preferably, a square block is fixedly connected to one side of the irregular frame, and a limiting plate is rotatably connected to the surface of the square block, with the surface of the limiting plate slidably connected to the sliding plate.
[0010] The aforementioned components achieve the following effect: they limit the position of the sliding plate, preventing the sliding plate from being in a relatively high position when the operator moves it, thus avoiding the possibility of the sliding plate colliding with the pumping unit body and causing damage to the sliding plate.
[0011] Preferably, a shock-absorbing pad is fixedly connected to the surface of the sliding plate, and the size of the shock-absorbing pad is adapted to the size of the sliding plate.
[0012] The aforementioned components achieve the following effects: they absorb the vibration force of the pumping unit body, reducing the impact of vibration on the pumping unit body. The damping pads can form a buffer zone between the pumping unit body and the sliding plate, distributing the vibration force evenly and further reducing damage to the entire device.
[0013] Preferably, the upper surface of the pumping unit body is provided with a disassembly device, the disassembly device including four fixing rods, all four fixing rods being fixedly connected to the surface of the pumping unit body, one end of each fixing rod being rotatably connected to a single-hole plate, a threaded rod being threadedly inserted into the single-hole plate, the arc surface of the threaded rod being threadedly connected to a cover plate, and one end of the threaded rod being fixedly connected to a polygonal plate.
[0014] The aforementioned components achieve the following effect: by setting up a disassembly device, the cover plate can be easily disassembled, avoiding the situation where the original connection method is more complicated and cumbersome, requiring a lot of time and effort, and may even require the use of multiple tools to complete the disassembly. This would cause the staff to need to find suitable tools to disassemble the cover plate, resulting in a certain extension of the maintenance time of the pumping unit body, thus improving the convenience of the device.
[0015] Preferably, a square rod is fixedly connected to the arc surface of the threaded rod, and the surface of the square rod is in contact with the cover plate.
[0016] The effect achieved by the above-mentioned components is to prevent the threaded rod from falling off, thus avoiding the situation where the threaded rod is rotated too many times, causing it to separate from the single-hole plate. This would require the operator to perform secondary installation, increasing the operator's workload.
[0017] Preferably, the arc surface of the fixing rod is fitted with a torsion spring, and the two ends of the torsion spring are respectively fixedly connected to the pumping unit body and the single-hole plate.
[0018] The aforementioned components achieve the following effect: they automatically open the single-hole plate while keeping it in the open state, facilitating further operations by the staff.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] 1. In this utility model, by setting a shock-absorbing device, the vibration of the pumping unit body is reduced, avoiding the pumping unit body from being subjected to its own or external forces during operation, which would cause a certain degree of vibration in the pumping unit body, damage to internal parts, and shorten the service life of the pumping unit, thus improving the practicality of the device.
[0021] 2. In this utility model, by setting up a disassembly device, the effect of conveniently disassembling the cover plate is achieved. This avoids the situation where the original connection method is more complicated and cumbersome, requiring a lot of time and effort, and may even require the use of multiple tools to complete the disassembly. As a result, the staff need to find suitable tools to disassemble the cover plate, which will extend the maintenance time of the pumping unit. This improves the convenience of the device.

Detailed Implementation
[0028] Reference Figure 1As shown, this utility model provides a technical solution: a vibration reduction system for an oil extraction pumping unit, including a pumping unit body 1, a cover plate 2 installed on the surface of the pumping unit body 1, and a vibration damping device 3 provided on the surface of the pumping unit body 1. By setting the vibration damping device 3, the vibration of the pumping unit body 1 is reduced, preventing the pumping unit body 1 from being subjected to forces applied by itself or external forces during operation, which could cause a certain degree of vibration, damage to internal parts, and shorten the service life of the pumping unit. This improves the practicality of the device. The upper surface of the pumping unit body 1 is provided with a disassembly device 4, which facilitates the disassembly of the cover plate 2. This avoids the original connection method being more complicated and cumbersome, requiring a lot of time and effort, and even requiring the use of multiple tools to complete the disassembly. This would cause the staff to need to find suitable tools to disassemble the cover plate 2, thus extending the maintenance time of the pumping unit body 1. This improves the convenience of the device.
[0029] The following section will explain the specific setup and function of its shock absorption device 3 and disassembly device 4.
[0030] Reference Figure 2 and Figure 3As shown in this embodiment: the shock absorption device 3 includes four irregularly shaped frames 33, which are slidably connected to the surface of the pumping unit body 1. The four irregularly shaped frames 33 are arranged in pairs, and each pair of irregularly shaped frames 33 has a fixed frame 32 slidably connected to its surface. A base plate 31 is fixedly connected to one side of each of the two fixed frames 32. A sliding plate 37 is slidably connected inside the irregularly shaped frame 33. Two springs 35 are fixedly connected to one side of the sliding plate 37, and one end of each spring 35 is fixedly connected to the irregularly shaped frame 33. A bolt 34 is threaded into the irregularly shaped frame 33, and the arc surface of the bolt 34 is threadedly connected to the fixed frame 32. When the operator needs to install pumping unit bodies 1 of different sizes, the operator first lifts one side of the pumping unit body 1, and then rotates the bolt 34 within the fixed frame 32 until... The arc surface of bolt 34 separates from the fixed frame 32, allowing the operator to pull the irregular frame 33 to slide within the fixed frame 32. The operator presses the sliding plate 37, compressing the spring 35 until the sliding plate 37 no longer hinders the movement of the irregular frame 33. The operator continues to push the irregular frame 33 until its inner surface is in contact with the surface of the pumping unit body 1. Then, the operator releases the sliding plate 37, and the spring 35's rebound force causes the sliding plate 37 to slide within the irregular frame 33 until its surface is in contact with the surface of the pumping unit body 1. This achieves the effect of adapting to pumping unit bodies 1 of different sizes, facilitating easy adjustment of the irregular frame 33's position, and enhancing the device's versatility and applicability. A square block 38 is fixedly connected to one side of the frame 33. A limit plate 39 is rotatably connected to the surface of the square block 38. The surface of the limit plate 39 is slidably connected to the sliding plate 37. When the operator needs to dampen the pumping unit body 1, the operator first pushes the sliding plate 37 to slide within the frame 33 until the sliding plate 37 no longer affects the movement of the limit plate 39. The operator can then rotate the limit plate 39 on the surface of the square block 38 until the surface of the limit plate 39 is in contact with the sliding plate 37. At this point, the position of the sliding plate 37 is restricted, preventing the sliding plate 37 from always being in a relatively high position when the operator moves it. This would prevent the sliding plate 37 from potentially colliding with the pumping unit body 1 when the operator pushes it. In the event of a collision that damages the sliding plate 37, a shock-absorbing pad 36 is fixedly connected to the surface of the sliding plate 37. The size of the shock-absorbing pad 36 is adapted to the size of the sliding plate 37. When the operator needs to dampen the pumping unit body 1, the operator first pushes the irregular frame 33 to move the sliding plate 37, which in turn moves the shock-absorbing pad 36 until the inner surface of the irregular frame 33 is in contact with the pumping unit body 1. The operator then rotates the limiting plate 39, which slides on the surface of the sliding plate 37, until the surface of the limiting plate 39 separates from the sliding plate 37. At this point, the rebound force of the spring 35 causes the sliding plate 37 to slide within the irregular frame 33, and the sliding plate 37 moves the shock-absorbing pad 36 until the surface of the shock-absorbing pad 36 is in contact with the surface of the pumping unit body 1.At this point, the vibration force of the pumping unit body 1 is absorbed, reducing the impact of vibration. The damping pad 36 forms a buffer zone between the pumping unit body 1 and the sliding plate 37, evenly distributing the vibration force and further reducing damage to the entire device.
[0031] Reference Figure 4 and Figure 5 As shown, specifically, the disassembly device 4 includes four fixing rods 41, all of which are fixedly connected to the surface of the pumping unit body 1. A single-hole plate 42 is rotatably connected to one end of each fixing rod 41. A threaded rod 43 is threadedly inserted into the single-hole plate 42. The arc surface of the threaded rod 43 is threadedly connected to the cover plate 2. A polygonal plate 44 is fixedly connected to one end of the threaded rod 43. A square rod 45 is fixedly connected to the arc surface of the threaded rod 43. The surface of the square rod 45 is in contact with the cover plate 2. When the operator needs to use the disassembly cover plate 2, the operator first rotates the threaded rod 43 within the cover plate 2. The threaded rod 43 drives the square rod 45 to move until the surface of the square rod 45 is in contact with the single-hole plate 42. The operator can then rotate the single-hole plate 42 until it no longer interferes with the operator's internal inspection of the pumping unit body 1. This achieves the effect of preventing the threaded rod 43 from falling off, avoiding the operator's risk of injury during rotation. When the threaded rod 43 is rotated too many times, it causes the threaded rod 43 to separate from the single-hole plate 42. This requires secondary installation by the operator, increasing their workload. The arc surface of the fixed rod 41 is fitted with a torsion spring 46, and the two ends of the torsion spring 46 are fixedly connected to the pumping unit body 1 and the single-hole plate 42, respectively. When the operator needs to remove the cover plate 2, the operator first rotates the threaded rod 43 inside the cover plate 2. The threaded rod 43 drives the square rod 45 to move until the square rod 45 is in contact with the surface of the single-hole plate 42. At this time, the threaded rod 43 and the cover plate 2 are completely separated. The torque of the torsion spring 46 drives the single-hole plate 42 to rotate until the single-hole plate 42 no longer affects the operator's maintenance inside the pumping unit body 1. At this time, the single-hole plate 42 is automatically opened and kept in the open state to facilitate further operation by the operator.
[0032] Working principle: The base plate 31 is fixedly connected to the ground, etc. When the operator needs to install the pumping unit body 1 of different sizes, the operator pushes the sliding plate 37 to slide within the irregular frame 33 until the sliding plate 37 no longer affects the movement of the limiting plate 39. The operator can then rotate the limiting plate 39 on the surface of the square block 38 until the surface of the limiting plate 39 is in contact with the sliding plate 37. The operator lifts one side of the pumping unit body 1 and then rotates the bolt 34 within the fixed frame 32 until the arc surface of the bolt 34 separates from the fixed frame 32. Then, the operator can pull the irregular frame 33 to slide within the fixed frame 32. The sliding plate 37 drives the shock-absorbing pad 36 to move until the irregular frame... The inner surface of the 33 is in contact with the pumping unit body 1. The operator rotates the limiting plate 39 and slides it on the surface of the sliding plate 37 until the surface of the limiting plate 39 separates from the sliding plate 37. At this time, the rebound force of the spring 35 drives the sliding plate 37 to slide within the irregular frame 33. The sliding plate 37 drives the shock-absorbing pad 36 to move until the surface of the shock-absorbing pad 36 is in contact with the surface of the pumping unit body 1. This achieves the effect of reducing the vibration of the pumping unit body 1, avoiding the pumping unit body 1 from being subjected to its own or external forces during operation, which would cause a certain degree of vibration in the pumping unit body 1. Vibration damages internal parts and shortens the service life of the pumping unit, thus improving the practicality of the device.
[0033] When the operator needs to disassemble cover plate 2, the operator first rotates the threaded rod 43 inside cover plate 2. The threaded rod 43 drives the square rod 45 to move until the square rod 45 is in contact with the surface of the single-hole plate 42. At this time, the threaded rod 43 and cover plate 2 are completely separated. The torque of the torsion spring 46 drives the single-hole plate 42 to rotate until the single-hole plate 42 no longer affects the operator's maintenance of the pumping unit body 1. This achieves the effect of convenient disassembly of cover plate 2, avoiding the original connection method which was more complicated and cumbersome, requiring a lot of time and effort, and even requiring the use of multiple tools to complete the disassembly. This caused the operator to need to find suitable tools to disassemble cover plate 2, resulting in a certain extension of the maintenance time of the pumping unit body 1. This improves the convenience of the device.
