Abstract
Description
Technical Field
[0001] This utility model belongs to the field of shipbuilding, and specifically relates to a ship pipe hanger. Background Technology
[0002] In the marine industry, various piping systems are crucial for the normal operation of ships. Systems such as propulsion, fuel delivery, water supply and drainage, and ventilation all rely on pipes to function. During navigation, ships experience continuous and complex vibrations due to factors such as wave impact and mechanical operation. As key components for fixing and supporting pipes, ship pipe hangers must ensure the stability of the pipes under vibration, preventing displacement and collisions. Their design must accommodate the diverse spatial layouts of ships and adapt to the unique marine environment, including humidity and high salinity, to ensure the safe and stable operation of the piping system and provide solid support for the overall performance of the ship.
[0003] Existing technologies have specifically developed some ship pipe hangers. For example, Chinese patent with announcement number "CN205663997U" discloses "a shockproof ship pipe hanger". It weakens the vibration force transmitted to the pipe hanger by the rubber material of the shock-absorbing strip itself. The remaining vibration force that cannot be weakened can be transmitted to the auxiliary strip through the transmission belt for final weakening. This makes the pipe hanger completely unaffected by the vibration of the ship's pipeline and prevents the pipe hanger from loosening and falling off due to long-term vibration.
[0004] Although the vibration force transmitted to the pipe hanger is weakened by the rubber material of the damping strip itself, the remaining vibration force that cannot be weakened can be transmitted to the auxiliary strip through the transmission belt for final weakening, so that the pipe hanger is ultimately completely unaffected by the vibration of the ship's pipeline, there is a risk of the nut loosening under long-term use. If the nut falls off, the probability of safety hazards will increase, and the risk of nut falling off cannot be effectively solved. Utility Model Content
[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a ship pipe hanger to solve the problems of ships.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A marine pipe hanger includes a base plate and a support. The base plate is fixedly mounted on the upper end of the support. Both the base plate and the support have circular openings on both sides. A U-shaped ring is slidably installed inside the circular opening. Anti-loosening nuts are provided on both sides of the end of the base plate away from the support. Two anti-loosening nuts are threaded to both sides of one end of the U-shaped ring. Fastening nuts are rotatably installed on both sides of the end of the support away from the base plate. The fastening nuts are also threaded to both sides of one end of the U-shaped ring. An installation plate is integrally formed at the center of the end of the base plate away from the support. Three buffer springs are fixedly installed on the end of the installation plate away from the base plate. A buffer plate is fixedly installed on the end of the three buffer springs away from the installation plate.
[0008] As a preferred technical solution, both outer rings at one end of the U-shaped ring are provided with external threads, and a protective sleeve is fixedly installed on the outer ring at the end of the U-shaped ring away from the external threads.
[0009] As a preferred technical solution, circular grooves are provided on both sides of the interior of the base plate, and a circular plate is integrally formed at one end of the two anti-loosening nuts near the base plate, and the circular plate is slidably installed in the inner ring of the circular groove.
[0010] As a preferred technical solution, multiple limiting grooves are provided inside both circular grooves, and multiple limiting posts are provided at one end of the two circular plates near the circular grooves. The multiple limiting posts are slidably installed in the inner circle of the limiting grooves.
[0011] As a preferred technical solution, both sides of the outer ring of the U-shaped ring are integrally formed with a stop block, and both anti-loosening nuts are provided with a first internal thread. Both anti-loosening nuts are threadedly connected to the U-shaped ring through the first internal thread, and both anti-loosening nuts are located at the end of the two stop blocks away from the protective sleeve.
[0012] As a preferred technical solution, the bracket has anti-slip grooves on both sides of the end away from the base plate, and the two fastening nuts have anti-slip plates integrally formed on the ends of the brackets near the brackets. The anti-slip plates are rotatably installed inside the anti-slip grooves. The inner rings of the two fastening nuts are provided with second internal threads, and the two fastening nuts are threaded to the outer rings on both sides of the U-shaped ring through the second internal threads.
[0013] As a preferred technical solution, two limiting plates are integrally formed on both sides of the upper end of the base plate, and limiting grooves are formed inside the two limiting plates. Two limiting protrusions are integrally formed on both sides of the outer ring of the buffer plate, and the two limiting protrusions are slidably installed inside the limiting plates through the limiting grooves.

[0015] First, multiple limiting posts are provided at one end of the circular plate near the circular groove. The limiting posts are slidably installed in the inner ring of the limiting groove, which effectively limits the rotation angle of the anti-loosening nut and prevents it from loosening due to excessive rotation, thus playing a reliable anti-loosening role.
[0016] Secondly, when the buffer spring absorbs vibration energy and undergoes elastic deformation, the buffer plate will move accordingly. The limiting protrusion slides in the limiting groove, which restricts the movement range of the buffer plate and ensures that the buffer plate performs buffering work within a reasonable stroke. This ensures that the buffer spring can fully exert its buffering effect, prevents the buffer plate from damaging other components due to excessive movement, and maintains the stability of the entire buffering system.

[0023] Example
[0024] refer to Figures 1-5This embodiment of a ship pipe hanger includes a base plate 12 and a bracket 13. The base plate 12 is fixedly mounted on the upper end of the bracket 13. Both the base plate 12 and the bracket 13 have circular openings 20 on both sides inside. A U-shaped ring 2 is slidably installed inside the circular opening 20. Anti-loosening nuts 6 are provided on both sides of the end of the base plate 12 away from the bracket 13. The two anti-loosening nuts 6 are threaded to both sides of one end of the U-shaped ring 2. Fastening nuts 14 are rotatably installed on both sides of the end of the bracket 13 away from the base plate 12. The fastening nuts 14 are also threaded to both sides of one end of the U-shaped ring 2. An installation plate 11 is integrally formed at the center of the end of the base plate 12 away from the bracket 13. Three buffer springs 8 are fixedly installed on the end of the installation plate 11 away from the base plate 12. A buffer plate 3 is fixedly installed on the end of the three buffer springs 8 away from the installation plate 11.
[0025] refer to Figures 1 to 4 The outer rings on both sides of one end of the U-ring 2 are provided with external threads 15. The outer ring of the U-ring 2 away from the external threads 15 is fixedly installed with a protective sleeve 1, which can effectively protect the U-ring 2 from damage.
[0026] refer to Figure 2 Both sides of the base plate 12 have circular grooves 18. The two anti-loosening nuts 6 are integrally formed with circular plates 7 at the ends of the base plate 12. The circular plates 7 are slidably installed in the inner ring of the circular grooves 18. Multiple limiting grooves 19 are provided inside the two circular grooves 18. Multiple limiting posts 17 are provided at the ends of the two circular plates 7 near the circular grooves 18. The multiple limiting posts 17 are slidably installed in the inner ring of the limiting grooves 19, which effectively limits the rotation angle of the anti-loosening nuts 6 and prevents them from loosening due to excessive rotation, thus playing a reliable anti-loosening role.
[0027] refer to Figures 2 to 3 Both sides of the outer ring of the U-shaped ring 2 are integrally formed with a stop block 5. The two anti-loosening nuts 6 are provided with a first internal thread 16. The two anti-loosening nuts 6 are threadedly connected to the U-shaped ring 2 through the first internal thread 16. The two anti-loosening nuts 6 are located at the end of the two stop blocks 5 away from the protective sleeve 1. They can be effectively threadedly connected to the outer ring of one end of the U-shaped ring 2 through the first internal thread 16.
[0028] refer to Figures 3 to 4The bracket 13 has anti-slip grooves 23 on both sides of the end away from the base plate 12. The two fastening nuts 14 are integrally formed with anti-slip plates 22 at the ends of the bracket 13. The anti-slip plates 22 are rotatably installed inside the anti-slip grooves 23. The inner rings of the two fastening nuts 14 are provided with second internal threads 21. The two fastening nuts 14 are threaded to the outer rings on both sides of the U-shaped ring 2 through the second internal threads 21. The anti-slip plates 22 are rotatably installed inside the anti-slip grooves 23. When the fastening nuts 14 are rotated to tighten the U-shaped ring 2, the cooperation between the anti-slip plates 22 and the anti-slip grooves 23 increases the friction, preventing the fastening nuts 14 from slipping during the tightening process and ensuring the smooth progress of the tightening operation.
[0029] refer to Figures 4 to 5 Two limiting plates 10 are integrally formed on both sides of the upper end of the base plate 12. Each limiting plate 10 has a limiting groove 9 inside. Two limiting protrusions 4 are integrally formed on both sides of the outer ring of the buffer plate 3. Both limiting protrusions 4 are slidably installed inside the limiting plate 10 through the limiting grooves 9. When the buffer spring 8 absorbs vibration energy and undergoes elastic deformation, the buffer plate 3 will move accordingly. The limiting protrusions 4 slide in the limiting grooves 9, limiting the movement range of the buffer plate 3 and ensuring that the buffer plate 3 performs buffering work within a reasonable stroke. This ensures that the buffer spring 8 can fully exert its buffering effect, prevents the buffer plate 3 from being damaged by excessive movement, and maintains the stability of the entire buffer system.
[0030] Operating principle and advantages: By rotating the anti-loosening nut 6, the position of the U-ring 2 within the circular opening 20 can be adjusted, achieving initial adaptation to pipes of different diameters. The anti-loosening nut 6 is threaded onto both sides of one end of the U-ring 2, and the bottom plate 12 has corresponding installation positions on both sides of the end away from the bracket 13. The bracket 13 has fastening nuts 14 rotatably installed on both sides of the end away from the bottom plate 12, also threaded onto both sides of one end of the U-ring 2. After initially adjusting the position of the U-ring 2, rotating the fastening nut 14 gradually tightens the U-ring 2. Since the fastening nut 14 is connected to the outer rings on both sides of the U-ring 2 through the second internal thread 21, as the fastening nut 14 tightens, the U-ring 2 is firmly fixed between the bracket 13 and the bottom plate 12, thereby securing the pipe... The pipe is held firmly in place to ensure it does not shift during ship operation. Circular grooves 18 are formed on both sides of the inner surface of the base plate 12. A circular plate 7 is integrally formed at one end of the anti-loosening nut 6 near the base plate 12. The circular plate 7 slides within the inner ring of the circular groove 18. This design ensures that the anti-loosening nut 6 maintains a stable position during rotational adjustment and does not experience radial displacement. Multiple limiting grooves 19 are formed inside the circular groove 18. Multiple limiting posts 17 are provided at one end of the circular plate 7 near the circular groove 18. The limiting posts 17 slide within the inner ring of the limiting groove 19, effectively limiting the rotation angle of the anti-loosening nut 6 and preventing excessive rotation that could lead to loosening, thus providing a reliable anti-loosening function. The stop blocks 5 integrally formed on both sides of the outer ring of the U-shaped ring 2 cooperate with the anti-loosening nut 6. After the anti-loosening nut 6 is connected to the U-shaped ring 2 through the first internal thread 16, it is located at the end of the stop block 5 away from the protective sleeve 1. The presence of the stop block 5 prevents the anti-loosening nut 6 from moving towards the end of the U-shaped ring 2 with the protective sleeve 1 when subjected to vibration or external force, further enhancing the anti-loosening effect. The bracket 13 has anti-slip grooves 23 on both sides of the end away from the base plate 12. The fastening nut 14 has an anti-slip plate 22 integrally formed at the end near the bracket 13. The anti-slip plate 22 is rotatably installed inside the anti-slip groove 23. When the fastening nut 14 is rotated to tighten the U-shaped ring 2, the cooperation between the anti-slip plate 22 and the anti-slip groove 23 increases the friction, preventing the fastening nut 14 from slipping during the tightening process, ensuring the smooth progress of the tightening operation. The inner ring of the fastening nut 14 has a second internal thread. Thread 21 connects to the outer rings on both sides of the U-shaped ring 2 via an internal thread. As the thread gradually tightens, the fastening nut 14 applies increasing pressure to the U-shaped ring 2, thus securing the pipe firmly. An integral mounting plate 11 is formed at the center of the end of the base plate 12 furthest from the bracket 13. Three buffer springs 8 are fixedly mounted on the end of the mounting plate 11 furthest from the base plate 12. The ends of the buffer springs 8 furthest from the mounting plate 11 are connected to a buffer plate 3. When the ship vibrates during navigation, the external pipe will sway. At this time, the buffer plate 3 first comes into contact with the vibration of the pipe, and the buffer springs 8 play a crucial buffering role. The buffer springs 8 have a certain degree of elasticity and can absorb vibration energy, converting the vibration of the pipe into the elastic deformation energy of the spring.When the pipe vibrates in a certain direction, the buffer spring 8 will compress or stretch accordingly based on the direction and amplitude of the vibration, thereby reducing the impact of pipe vibration on the overall structure of the hanger and effectively protecting the pipe from damage caused by excessive vibration. Two limiting plates 10 are integrally formed on both sides of the upper end of the base plate 12, with limiting grooves 9 inside each plate. Two limiting protrusions 4 are integrally formed on both sides of the outer ring of the buffer plate 3. The limiting protrusions 4 are slidably installed inside the limiting plates 10 through the limiting grooves 9. This limiting structure plays an important role in the buffering process. When the buffer spring 8 absorbs vibration energy and undergoes elastic deformation, the buffer plate 3 moves accordingly, and the limiting protrusions 4 slide within the limiting grooves 9, limiting the range of movement of the buffer plate 3 and ensuring that the buffer plate 3 performs its buffering work within a reasonable stroke. This ensures that the buffer spring 8 can fully exert its buffering effect, prevents the buffer plate 3 from damaging other components due to excessive movement, and maintains the stability of the entire buffering system.
