Description

Technical Field

[0001] The utility model relates to the technical field of oil well pipeline maintenance equipment, in particular to an auxiliary device for repairing oil well pipelines. Background Art

[0002] Oil well pipelines are important infrastructures in the oil and gas industry for drilling, extracting, and transporting oil and gas. They run through the entire oil and gas production chain, from underground reservoirs to surface treatment facilities, and then to long-distance transportation to end-users.

[0003] With the expansion of oil and gas resource development into deep sea and unconventional fields, pipeline technology will continuously face challenges of higher pressure and more complex environments. When the material of the oil well pipeline shows cracking, electrochemical corrosion, biological corrosion, and the influence of the construction environment, etc., it will cause leakage of the oil well pipeline. After the leaked crude oil seeps into the soil, it will change the physical and chemical properties, damage vegetation, and the highly saline produced water will pollute groundwater, threatening the safety of drinking water. Moreover, the leakage of the pipeline causes the volatilization of oil and gas to form combustible gases (such as methane, hydrogen sulfide), which are prone to explosion when encountering an open flame. Therefore, when the oil well pipeline leaks, it should be repaired in time to avoid further expansion of pollution or accidents. For example, the prior application with the publication number CN204756297U discloses a detection and repair device for oil pipelines, which temporarily repairs the leakage point by spraying a repair agent on the leakage point of the pipeline, and waits for subsequent maintenance personnel to arrive for further treatment.

[0004] Since some oil well pipelines are laid on the ground or underground, the oil well pipeline usually includes multiple layers such as casing pipes and tubing. When the casing pipe is deformed, broken, or there is external leakage between pipes, it is necessary to fix the pipeline and adjust it to an appropriate angle before unthreading and releasing the stuck, repairing the casing, etc. At present, the fixing of oil well pipelines is mainly through fixed support frames, which is not conducive to adjusting the height and inclination angle of the oil well pipeline, resulting in low repair efficiency.

[0005] Therefore, those skilled in the art are committed to developing an auxiliary device for repairing oil well pipelines, which is conducive to fixing and supporting the oil well pipeline and facilitating subsequent rapid repair. Summary of the Utility Model

[0041] As Figure 1 、 Figure 2 and Figure 3 shown, an auxiliary device for repairing oil well pipelines includes

[0042] a lifting plate 1, on which a first pipeline clamping assembly 2 and a second pipeline clamping assembly 3 are arranged, and a guiding assembly 4 is arranged between the first pipeline clamping assembly 2 and the second pipeline clamping assembly 3 and the lifting plate 1;

[0043] a shock-absorbing plate 5, which is connected to the lifting plate 1 through a first lifting assembly 6 and a second lifting assembly 7, and the shock-absorbing plate 5 is arranged on a shock-absorbing assembly 8.

[0044] In the present utility model, after the first pipeline clamping assembly 2 and the second pipeline clamping assembly 3 clamp oil well pipelines with different diameters, the support height and support angle of the oil well pipelines are adjusted through the first lifting assembly 6 and the second lifting assembly 7, enhancing the device's ability to adapt to different terrains and meeting the requirements of different pipeline repair positions. Moreover, the cooperation between the shock-absorbing plate 5 and the shock-absorbing assembly 8 effectively buffers the pipeline vibration and protects the pipeline structure.

[0045] As Figure 1 、 Figure 2As shown, in some embodiments, both the first pipe clamping assembly 2 and the second pipe clamping assembly 3 include clamping blocks 9. The clamping blocks 9 have arc-shaped surfaces. The four clamping blocks 9 are respectively located at the four corners of a rectangle, and an adjusting assembly is provided between two adjacent clamping blocks 9. The adjusting assembly is used to adjust the distance between two adjacent clamping blocks 9 to adapt to pipes of different diameters.

[0046] Specifically, the adjusting assembly includes a first connecting plate 10 and a second connecting plate 11. The first connecting plate 10 and the second connecting plate 11 are respectively fixedly connected to the side walls of two adjacent clamping blocks 9. The first connecting plate 10 is rotatably connected with a first rotating prism 12. The first rotating prism 12 is connected with a rotating sleeve 13. The rotating sleeve 13 has internal threads. The second connecting plate 11 is rotatably connected with a second rotating prism 14. The second rotating prism 14 is connected with a rotating lead screw 15. The end of the rotating lead screw 15 is inserted into the rotating sleeve 13. During the adjustment process, the first rotating prism 12 or the second rotating prism 14 is rotated to adjust the distance that the rotating lead screw 15 is inserted into the rotating sleeve 13, thereby adjusting the distance between two adjacent clamping blocks 9 to adapt to oil well pipes of different diameters.

[0047] As Figure 1 、 Figure 2 shown, in the embodiment, the clamping block 9 has a rotating groove 16. The rotating groove 16 is arranged on the side surface of the clamping block 9. A rotating rod 17 is arranged in the rotating groove 16. One end of the rotating rod 17 is hinged to the clamping block 9 through a rotating pin. The other end of the rotating rod 17 is connected with a clamping member 18. In order to increase the fitting area between the clamping member 18 and the outer surface of the oil well pipe, the clamping member 18 is arc-shaped. An anti-slip layer is also arranged on the surface of the clamping member 18. The anti-slip layer enhances the friction between the clamping member 18 and the pipe, preventing the pipe from sliding during the clamping process.

[0048] As Figure 1 、 Figure 2 shown, in another embodiment, the guiding assembly 4 includes a guide rail 19 installed on the lifting plate 1. A slider 20 that cooperates with the guide rail 19 is arranged on the guide rail 19. The slider 20 is also connected with a clamping block 9, such that when two adjacent clamping blocks 9 move, they move along the length direction of the guide rail 19.

[0049] As Figure 1 、 Figure 3As shown, in the embodiment, both the first lifting assembly 6 and the second lifting assembly 7 include a first support column 21, a second support column 22, a third support column 23, and a fourth support column 24. The ends of the first support column 21 and the second support column 22 are respectively connected to the lifting plate 1, and the ends of the third support column 23 and the fourth support column 24 are connected to the shock-absorbing plate 5. A height adjustment assembly is installed between the first support column 21, the second support column 22, the third support column 23, and the fourth support column 24. By adjusting the height adjustment assembly, the distance between the first support column 21 and the second support column 22 and the third support column 23 and the fourth support column 24 is adjusted, thereby adjusting the distance between the lifting plate 1 and the shock-absorbing plate 5. Moreover, when adjusting the height adjustment assemblies on the first lifting assembly 6 or the second lifting assembly 7 respectively, the inclination angle of the lifting plate 1 can be adjusted, so that the clamped oil well pipeline has a certain inclination angle, which is beneficial to subsequent maintenance.

[0050] Specifically, the height adjustment assembly includes a first hinge rod 25, a second hinge rod 26, a third hinge rod 28, and a fourth hinge rod 29. The ends of the first hinge rod 25 and the second hinge rod 26 are respectively hinged to the first support column 21 and the third support column 23. The other ends of the first hinge rod 25 and the second hinge rod 26 are hinged through a first hinge member 27, and a first adjustment screw 31 is also fixedly connected to the first hinge member 27. The ends of the third hinge rod 28 and the fourth hinge rod 29 are respectively hinged to the second support column 22 and the fourth support column 24. The other ends of the third hinge rod 28 and the fourth hinge rod 29 are hinged through a second hinge member 30, and a second adjustment screw 32 is fixedly connected to the second hinge member 30. The thread rotation directions of the first adjustment screw 31 and the second adjustment screw 32 are opposite, and the first adjustment screw 31 and the second adjustment screw 32 are threadedly connected through an adjustment member 33. Rotating the adjustment member 33 makes the lifting plate 1 and the shock-absorbing plate 5 approach or move away from each other, thereby precisely adjusting the height of the lifting plate 1.

[0051] In this embodiment, the shock-absorbing assembly 8 includes a guide post 34 installed at the bottom of the shock-absorbing plate 5. The end of the guide post 34 passes through a guide sleeve 35, and the guide sleeve 35 is installed on the bottom plate 37. A shock-absorbing spring 36 is sleeved outside the guide post 34 and the guide sleeve 35, and both ends of the shock-absorbing spring 36 are respectively abutted against the shock-absorbing plate 5 and the bottom plate 37. During the maintenance process, when the oil well pipeline vibrates, the shock-absorbing spring 36 can effectively absorb and buffer the vibration energy, thereby protecting the pipeline from vibration damage.

[0052] In other embodiments, an elastic pre-tightening device is added to the clamping members 18 of the first pipeline clamping assembly 2 and the second pipeline clamping assembly 3, and a spring pre-tightening mechanism provides a continuous and stable pre-tightening force for the oil well pipeline. During the maintenance process, even if the pipeline has a slight displacement tendency due to external vibration or the influence of the operator, the elastic pre-tightening device can immediately respond and provide corresponding clamping force, effectively avoiding the loosening of the pipeline and further improving the fixing stability of the pipeline.

[0053] The elastic pre-tightening device is configured by installing pre-tightening springs on the arc surface of the clamping member 18, and the other ends of multiple pre-tightening springs are connected to a pre-tightening clamping member having the same shape as the clamping member 18.
