Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a pipeline connector for an oil tank. Background Technology

[0002] In the fields of petrochemicals, warehousing, and transportation, oil tanks are the core equipment for oil storage, and their pipeline connectors are key components ensuring the efficient and safe transportation of oil. Currently, oil tank pipeline connectors are widely used in various oil tank systems, undertaking the important function of connecting different oil tanks or oil tanks to transportation pipelines. They are the core connecting devices for realizing oil transfer and distribution, and their performance directly affects the operating efficiency and safety of the oil tank system, making them an indispensable part of oil tank equipment.

[0003] The main structure of existing oil tank pipeline couplings typically includes a foundation support component and a docking connection component. The foundation is mostly supported by a base plate, on which a support frame is installed to fix the oil tank. The connection part consists of pipes and the coupling body. The coupling body is connected to the corresponding oil tank pipes on both sides. Some couplings are initially tightened with bolts, fixing blocks, and other components to ensure basic connection stability. The overall structure is designed around the core function of "bearing load and docking" to meet the oil transportation needs under normal operating conditions.

[0004] However, existing oil tank pipeline joints still have significant drawbacks. On the one hand, the joints bear the pressure of oil transportation for extended periods, yet generally lack specific support structures. After prolonged use, the joints are prone to deformation and loosening due to continuous stress, severely affecting their stability and increasing the risk of oil leakage. On the other hand, the connection methods at the joints are complex, often relying on combinations of multiple bolts and nuts for fastening. Disassembly requires multiple people to work together, which is not only time-consuming and labor-intensive but also extends equipment inspection and maintenance time, reducing overall operational efficiency. Therefore, a new type of pipeline joint for oil tanks is proposed to solve these problems. Utility Model Content

[0031] 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.

[0032] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a pipeline connector for an oil tank, comprising a base plate 1. Two support frames 2 are fixedly connected to the top left and right sides of the base plate 1. An oil tank 8 is fixedly connected to the top of the left support frame 2, and an oil tank 3 is fixedly connected to the top of the right support frame 2. A pipeline 4 is fixedly connected to the left side of the oil tank 3, and a connector 5 is fixedly connected to the left side of the pipeline 4. Fixing blocks 10 are fixedly connected to both the front and rear sides of the connector 5. A pipeline 7 is fixedly connected to the right side of the oil tank 8, and a connector 6 is fixedly connected to the right side of the pipeline 7. Fixing blocks 10 are fixedly connected to the front and rear sides of the connector 6. Bolts 9 are threaded inside the fixing blocks 10, and nuts 11 are threaded on the side of the bolts 9 closest to the connector 6. A slide rail 13 is fixedly connected to the top center of the base plate 1, and a motor is fixedly connected to the front interior of the slide rail 13. 21. A threaded rod 19 is fixedly connected to the output end of the motor 21. A stop block 23 is rotatably connected to the rear side of the threaded rod 19. A sliding rod 24 is threadedly connected to the outer side of the threaded rod 19. An X-shaped bracket 22 is rotatably connected to the rear side of the slide rail 13. The bottom front X-shaped bracket 22 is slidably connected to the inside of the slide rail 13. The top rear X-shaped bracket 22 is rotatably connected to the top plate 12. The top front X-shaped bracket 22 is slidably connected to the inside of the top plate 12. The bottom plate 1 is the core load-bearing component. Two support frames 2 are provided on the left and right sides of the top. The weight of oil tank 1 3 and oil tank 2 8 and the internal oil pressure are evenly distributed to the bottom plate 1. This avoids the oil tank tilting and pipeline deformation caused by uneven force during long-term use, significantly improves the overall stability of the system, and reduces the risk of pipeline breakage and oil leakage. The adjustment mechanism in the middle of the bottom plate 1 realizes flexible adjustment of the height at the docking point. When pipeline maintenance or replacement of connectors is required, the starter motor 21 drives the threaded rod 19 to rotate, causing the sliding rod 24 to slide along the slide rail 13, thereby pushing the X-shaped bracket 22 to expand or retract, achieving height adjustment of the top plate 12. During pipeline connection, connector 5 and connector 6 form a double-fastening structure through the fixing blocks 10 on both the front and rear sides, bolts 9, and nuts 11. The threaded connection between bolts 9 and fixing blocks 10 provides high-strength fastening, resisting the impact of pressure fluctuations and equipment vibrations during oil transportation, preventing loosening of the connectors. The secondary fixing of nuts 11 further locks the position of bolts 9, preventing thread loosening, ensuring a long-term tight fit of the connectors, improving sealing performance, and reducing the risk of oil leakage, making it particularly suitable for flammable, explosive, or corrosive oil transportation scenarios.

[0033] Reference Figures 1-3The first connector 5 has pin housings 16 fixedly connected to both the front and rear ends on the right side. A bolt pin 15 is slidably connected inside the pin housing 16. A spring 14 is fitted around the outside of the bolt pin 15, and a blocking plate 17 is fixedly connected to the outside of the bolt pin 15. A nut 18 is threadedly connected to the side of the bolt pin 15 away from the pin housing 16, and the nut 18 abuts against the second connector 6. The pin housing 16 on the right side of the first connector 5 provides a stable installation space for the bolt pin 15, which can slide along the pin housing 16, facilitating precise insertion into the second connector 6 during docking. This pin-type connection, together with the bolt connection of the fixing block 10, forms a "double locking" system, tightening the connector from multiple angles from both ends. Compared to a single connection method, this significantly improves the docking strength, effectively resists loosening caused by long-term vibration, and extends the service life of the connector. Furthermore, the spring 14 and the blocking plate 17 on the outside of the bolt pin 15 constitute an elastic compensation structure. During oil transportation, pipelines may experience thermal expansion and contraction due to temperature changes such as summer sun exposure and winter low temperatures, or slight vibrations caused by pump operation. The elasticity of spring 14 absorbs these minor displacements, preventing wear or cracks at the joint contact surface caused by rigid connections. The baffle plate 17 limits the extension and contraction range of spring 14, preventing excessive stretching or compression failure and ensuring long-term stability of the elastic compensation function. Simultaneously, if there are minor dimensional deviations in the joint installation, the elastic force of spring 14 can push bolt pin 15 to adaptively adjust its position, ensuring a tight fit between joint 15 and joint 26, reducing sealing gaps. Furthermore, the abutting design between nut 28 and joint 26 further enhances the tightening effect of bolt pin 15. When nut 18 is tightened, continuous pressure is applied to joint 6, forcing the contact surfaces of the joints to fit tightly together and improving sealing performance. At the same time, nut 18 can lock the bolt pin 15 in place, preventing it from loosening during vibration and avoiding oil leakage from the joint gap. This ensures the safety and environmental friendliness of the transportation process, and is especially suitable for high-viscosity or toxic oil transportation scenarios.

[0034] Reference Figure 1 , Figure 4 and Figure 5 The stop block 23 is fixedly connected to the top center of the base plate 1. The adjustment mechanism provides key support and limit protection, significantly improving the stability and safety of the adjustment process. The stop block 23 can limit the sliding range of the sliding rod 24. When the motor 21 drives the sliding rod 24 to slide backward, the stop block 23 can prevent the sliding rod 24 from moving too far backward, avoiding it from disengaging from the threaded rod 19 or pressing against the X-shaped bracket 22, which would cause structural damage.

[0035] Reference Figure 1 , Figure 4 and Figure 5The sliding rod 24 is slidably connected to the top of the base plate 1. This sliding engagement optimizes the force distribution and operational stability of the adjustment mechanism, providing a reliable foundation for the flexible adjustment of the X-shaped bracket 22. The top of the base plate 1 provides a flat and wide sliding contact surface for the sliding rod 24. Compared to relying solely on the slide rail 13 for support, adding support to the top of the base plate 1 disperses the pressure on the sliding rod 24, reduces friction and wear between the sliding rod 24 and the slide rail 13, and extends the service life of both. Simultaneously, the flat contact surface prevents the sliding rod 24 from jamming or shifting during sliding, ensuring smooth linear movement and improving the operating efficiency of the adjustment mechanism. The sliding connection between the sliding rod 24 and the base plate 1 facilitates later maintenance. If the sliding rod 24 or the slide rail 13 malfunctions, the operator can directly...

[0036] Reference Figure 2 and Figure 3 One end of the spring 14 is fixedly connected to the inner wall of the pin housing 16, and the other end is fixedly connected to the outer wall of the baffle plate 17. This fixing method restricts the extension and retraction direction of the spring 14, preventing it from shifting or twisting under force, and ensuring that the spring 14 always extends and retracts axially, precisely providing elastic force to the bolt pin 15. When pipeline vibration or temperature changes cause slight displacement of the connector, the spring 14 can extend and retract uniformly axially to absorb the impact force, prevent the bolt pin 15 from rigidly colliding with the connector 6, and reduce component wear.

[0037] Reference Figure 2 and Figure 3 The baffle plate 17 is slidably connected to the inner wall of the pin housing 16. The inner wall of the pin housing 16 provides a precise sliding track for the baffle plate 17. The sliding fit between the baffle plate 17 and the pin housing 16 restricts the movement direction of the bolt pin 15, ensuring that it always slides axially. This prevents the bolt pin 15 from shifting or tilting during docking, ensuring that it is accurately inserted into the hole of the connector 2 6, reducing installation difficulty and improving docking efficiency. Especially during manual operation, it can reduce installation errors caused by pin misalignment and shorten construction time. Secondly, the baffle plate 17 can effectively protect the spring 14 and prevent it from excessive deformation. When the bolt pin 15 is pulled outward, the blocking plate 17 slides outward to the outside of the pin housing 16, and the spring 14 is stretched. When the blocking plate 17 slides to the end of the inner wall of the pin housing 16, it will be blocked and cannot continue to move, thus preventing the spring 14 from being overstretched beyond its elastic limit and breaking. When the bolt pin 15 is pushed inward, the blocking plate 17 squeezes the spring 14, and the inner wall of the pin housing 16 can limit the movement distance of the blocking plate 17, preventing the spring 14 from being over-compressed and failing.

[0038] Reference Figure 2 and Figure 3The bolt pin 15 penetrates and is threaded into the interior of the second connector 6. This through-connection allows the bolt pin 15 to extend from the pin housing 16 of the first connector 5 into the interior of the second connector 6, creating a tightening force across the mating surfaces. Compared to surface-fit connections, this deep connection more effectively resists the tendency of the connector to separate, especially at high oil transfer pressures, preventing gaps from forming due to pressure impacts and reducing the risk of leakage. The threaded connection possesses self-locking and high-strength tightening characteristics. The threaded engagement between the bolt pin 15 and the second connector 6 generates continuous axial pressure, forcing the contact surfaces of the first connector 5 and the second connector 6 to fit tightly together, eliminating sealing gaps. Simultaneously, the self-locking function of the threaded connection prevents the bolt pin 15 from loosening during vibration, avoiding a decrease in connection strength after long-term use. Furthermore, the threaded connection facilitates disassembly and installation. When it is necessary to inspect the connector or replace parts, simply unscrew the bolt pin 15 to separate the connector, making operation convenient and reducing maintenance difficulty.

[0039] Reference Figure 2 and Figure 3 A protruding block 20 is fixedly connected to the right side of connector 26, and the protruding block 20 abuts against connector 15. The protruding block 20 has a positioning and guiding function. During the docking installation, the protruding block 20 can first contact connector 15 to guide connector 26 to accurately align with connector 15, avoiding poor sealing or component damage caused by misalignment. This positioning function simplifies the installation operation, reduces the time and error of manual alignment, and improves construction efficiency. Especially in the docking of large oil tank pipelines, it can reduce the workload of operators and ensure docking accuracy.

[0040] Working principle: When the operator aligns connector 5 and connector 6, the protrusion 20 on connector 6 is inserted into the groove of connector 5. Then, the operator presses the bolt pin 15 through the grooves of connector 5 and connector 6, compressing the spring 14. The nut 11 is then rotated into the bolt pin 15, thus fixing the two connectors in place. Both connectors 5 and 6 are fixedly connected to fixing blocks 10, which are further secured by bolts 9. When the oil tank begins to transfer oil, the pipeline lacks a supporting structure, and time... Long-term use can damage pipes and joints. A fine-tuning device provides support for the joint. This device is driven by a motor 21 to rotate the threaded rod 19. The stop block 23 is fixed on the base plate 1, so that the threaded rod 19 only rotates and does not move. This allows the sliding rod 24 to move along the threaded rod 19. One side of the X-shaped bracket 22 is fixedly connected to the slide rail 13, and the other side moves along the slide rail 13. This causes the X-shaped bracket 22 to deform, thereby moving the top plate 12 up and down, thus providing support for the joint.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
