Description

Technical Field

[0001] This utility model relates to the field of pipeline construction technology, and in particular to a pipeline stabilization device for long-distance natural gas pipeline construction. Background Technology

[0002] The pipeline stabilization device is an important piece of equipment to ensure the safe and stable laying of natural gas long-distance pipelines. Its main function is to fix the position of the natural gas long-distance pipeline and reduce pipeline displacement caused by factors such as soil settlement and external impact. During pipeline construction, especially when crossing areas with different geological conditions, such as soft soil areas, mountainous areas or under rivers, the pipeline stabilization device can keep the pipeline in the designed position and prevent pipeline deformation or damage.

[0003] However, traditional pipeline stabilization devices used in long-distance natural gas pipeline construction have poor stability for pipeline position and are easily displaced by external factors. When performing pipeline connection work, it is difficult to ensure the alignment accuracy of pipeline interfaces, which leads to misalignment of interfaces, increases welding difficulty, reduces welding quality, and may even lead to safety hazards such as natural gas leakage.

[0004] Therefore, it is necessary to provide a new pipeline stabilization device for long-distance natural gas pipeline construction to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a convenient, easy-to-use, and position-controlling device for stabilizing natural gas long-distance pipelines, which can apply uniform support force to two pipelines.

[0006] To solve the above-mentioned technical problems, the present invention provides a natural gas long-distance pipeline construction and stabilization device comprising: a mounting base, wherein two movable seats are provided inside the mounting base, and a connecting column is fixedly installed on the top of each of the two movable seats; two first cylinders are provided on the top of the mounting base; the top ends of the two connecting columns extend outside the mounting base and are respectively fixedly connected to the two first cylinders; an annular connecting plate is fixedly installed at the close ends of the two first cylinders; the annular connecting plate is provided with a communicating hole; and two first screws are rotatably installed on the top of the mounting base, with a single hexagonal connector fixedly installed at the close ends of the two first screws. The first cylinder has two annular connecting plates threadedly connected to the outer sides of the two first screws. Each of the two first cylinders has an upper clamping plate and a lower clamping plate. A second rotating rod is rotatably mounted on both sides of each of the two connecting columns.

A second screw is rotatably mounted on the top of the upper clamping plate, and the second screw passes through the internally threaded cover and is threadedly connected to it.

[0007] Preferably, one side of the mounting base is provided with a connecting slot, and one side of the movable base is provided with a mounting groove. A stop block is hinged in the mounting groove, one end of the stop block extends into the connecting slot, a spring is fixedly installed on one side of the stop block, and the other end of the spring is fixedly connected to the movable base.

[0008] Preferably, two support plates are fixedly installed on the top of the mounting base, and the ends of the two first screws that are far apart from each other are respectively rotatably installed on the two support plates.

[0009] Preferably, two rolling shafts are rotatably mounted on the bottom of the movable seat, and the outer wall of the rolling shafts contacts the inner wall of the mounting seat.

[0013] Compared with related technologies, the natural gas long-distance pipeline construction and stabilization device provided by this utility model has the following beneficial effects:

[0014] This utility model provides a pipeline stabilization device for long-distance natural gas pipeline construction. Through the cooperation of a connecting hole, an annular connecting plate, a support plate, a hexagonal connecting block, a first screw, a first cylinder, a connecting column, a movable seat, and a rolling shaft, during installation or when encountering external interference, the device rotates the hexagonal connecting block to allow the protective cylinder to wrap around the pipeline. This applies uniform support force from both sides of the pipeline, reducing pipeline swaying and displacement, preventing the pipeline from being scratched or squeezed by surrounding rocks, soil, or other sharp objects, and reducing the risk of pipeline leakage. The device also includes a threaded groove, a protective pad, a lower clamping plate, a second rotating rod, a first rotating rod, a fixing lug, a limiting block, an upper clamping plate, and a control block. The second screw and the internal threaded cap work together to firmly fix the pipeline position during construction, preventing displacement due to its own weight, external impacts, or soil pressure. This keeps the pipeline in the set position, avoiding construction inconvenience and safety hazards caused by pipeline displacement. Through the cooperation of the mounting groove, spring, stop block, connecting slot, moving seat, and mounting seat, it can be ensured that the first cylinder can accurately stop in the required position every time, providing stable support and protection for the pipeline. This effectively prevents damage to the pipeline due to displacement of the first cylinder, reduces stress concentration caused by changes in the pipeline's position, and thus improves the pipeline's safety and service life.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of a preferred embodiment of the natural gas long-distance pipeline construction stabilization device provided by this utility model; Figure 2 for Figure 1 The diagram shows a cross-sectional view of the structure.

[0023] Figure 5 for Figure 1The diagram shows the movable seat engaging with the mounting base via a stop block. The pipeline stabilization device for long-distance natural gas pipeline construction includes: a mounting base 4, within which are two movable seats 18. A connecting column 13 is fixedly installed on the top of each of the two movable seats 18. Two first cylinders 6 are located on the top of the mounting base 4. These first cylinders 6 prevent the pipeline from being scratched or squeezed by surrounding rocks, soil, or other sharp objects, reducing the risk of pipeline leakage. The tops of the two connecting columns 13 extend outside the mounting base 4 and are fixedly connected to the two first cylinders 6 respectively. An annular connecting plate 8 is fixedly installed at the adjacent ends of the two first cylinders 6. The annular connecting plate 8 has a connecting hole 7. Two first screws 1 are rotatably mounted on the top of the mounting base 4. A hexagonal connecting block 2 is fixedly installed at the adjacent ends of the two first screws 1. By rotating the hexagonal connecting block 2, the device that protects the pipeline by wrapping the protective cylinder can apply uniform support force from both sides of the pipeline, reducing pipeline leakage. To prevent swaying and displacement, the two annular connecting plates 8 are threadedly connected to the outer sides of the two first screws 1. Each of the two first cylinders 6 is provided with an upper clamping plate 15 and a lower clamping plate 19. The upper clamping plate 15 and the lower clamping plate 19 can firmly fix the position of the pipe, thereby preventing the pipe from displacing due to its own weight, external collision or soil pressure. The two connecting columns 13 are rotatably mounted with second rotating rods 12 on both sides. The other end of the second rotating rod 12 is fixedly mounted with a first rotating rod 11. The outer sides of the first rotating rod 11 and the second rotating rod 12 are slidably mounted with fixing ears 5. The other ends of the two fixing ears 5 are fixedly connected to the upper clamping plate 15 and the lower clamping plate 19. The top of the first cylinder 6 is fixedly mounted with an internal threaded cover 14. The top of the upper clamping plate 15 is rotatably mounted with a second screw 9. The second screw 9 passes through the internal threaded cover 14 and is threadedly connected to the internal threaded cover 14.

[0024] The mounting base 4 has a connecting slot 25 on one side, and the movable base 18 has a mounting slot 22 on one side. A stop block 24 is hinged in the mounting slot 22. One end of the stop block 24 extends into the connecting slot 25. A spring 23 is fixedly installed on one side of the stop block 24. The other end of the spring 23 is fixedly connected to the movable base 18. When the movable base 18 moves, it can ensure that the first cylinder 6 can accurately stop at the required position each time, providing stable support and protection for the pipeline.

[0025] Two support plates 3 are fixedly installed on the top of the mounting base 4, and the ends of the two first screws 1 that are far apart from each other are respectively rotatably installed on the two support plates 3.

[0026] Two rolling shafts 17 are rotatably mounted on the bottom of the movable seat 18, and the outer wall of the rolling shafts 17 is in contact with the inner wall of the mounting seat 4.

[0027] The threads of the two first screws 1 are arranged opposite each other.

[0028] Multiple protective pads 16 are fixedly installed on the inner walls of the upper clamping plate 15 and the lower clamping plate 19. A limiting block 10 is fixedly installed on the end of the first rotating rod 11 away from the second rotating rod 12. Threaded grooves 20 are provided on the outer sides of the second rotating rod 12 and the first rotating rod 11. A control block 21 is fixedly installed on the fixing ear 5. One end of the control block 21 is in contact with the threaded groove 20.

[0029] The two threaded grooves 20 are arranged opposite each other.

[0030] The working principle of the natural gas long-distance pipeline construction stabilization device provided by this utility model is as follows:

[0031] First, two pipes are simultaneously passed through the two first cylinders 6. Then, the second screw 9 is rotated, causing the upper clamping plate 15 to descend. As the upper clamping plate 15 descends, the first rotating rod 11 is rotated via the control block 21. The first rotating rod 11 drives the second rotating rod 12 to rotate, at which point the lower clamping plate 19 rises. The upper clamping plate 15 and the lower clamping plate 19 simultaneously clamp and fix the pipes, aligning the ends of the two pipes that are closest to each other. Then, the pipes are welded. After completion, when the position of the two first cylinders 6 on the pipes needs to be adjusted, the second screw 9 is rotated in the opposite direction. The second screw 9 is used to remove the pipe clamping mechanism. Then, a tool is used to rotate the hexagonal connecting block 2, which in turn drives the two first cylinders 6 to move relative to each other via the two first screws 1, thereby applying a uniform supporting force to the two pipes. To prevent damage to the pipes due to the displacement of the first cylinders 6, when the two first cylinders 6 move relative to each other and reach a certain distance, the spring 23 pushes one end of the abutment block 24 into the connecting slot 25, ensuring that the first cylinders 6 can accurately stop at the required position each time. Then, the second screw 9 is rotated again to clamp the pipe.

[0032] Compared with related technologies, the natural gas long-distance pipeline construction and stabilization device provided by this utility model has the following beneficial effects:

[0033] This utility model provides a pipeline stabilization device for long-distance natural gas pipeline construction. Through the cooperation of a connecting hole 7, annular connecting plate 8, support plate 3, hexagonal connecting block 2, first screw 1, first cylinder 6, connecting column 13, movable seat 18, and rolling shaft 17, during installation or when encountering external interference, the device rotates the hexagonal connecting block 2 to protect the pipeline by enveloping the cylinder. This applies uniform support force from both sides of the pipeline, reducing pipeline swaying and displacement, preventing the pipeline from being scratched or squeezed by surrounding rocks, soil, or other sharp objects, and reducing the risk of pipeline leakage. The device also includes a threaded groove 20, protective pad 16, lower clamping plate 19, second rotating rod 12, first rotating rod 11, fixing lug 5, limiting block 10, and upper clamping plate 1. 5. The control block 21, the second screw 9, and the internal threaded cover 14 work together to firmly fix the position of the pipeline during construction, thereby preventing the pipeline from shifting due to its own weight, external collisions, or soil pressure, keeping the pipeline in the set position, and avoiding construction inconvenience and safety hazards caused by pipeline displacement. Through the cooperation of the mounting groove 22, spring 23, stop block 24, connecting slot 25, moving seat 18, and mounting seat 4, it can be ensured that the first cylinder 6 can accurately stop in the required position every time, providing stable support and protection for the pipeline, effectively preventing the pipeline from being damaged due to the displacement of the first cylinder 6, reducing stress concentration caused by changes in the position of the pipeline, thereby improving the safety and service life of the pipeline.
