[0019] Please refer to Figures 1 - 10 , the present invention provides a technical solution: a multi-stage steplessly adjustable damping universal pipeline vibration damping device, including a bottom plate 1 and a damping mechanism 3. Four groups of ladle walls 2 are provided on the upper side of the bottom plate 1, and the four groups of ladle walls 2 are distributed in an equidistant circular shape.

[0020] The fixing member 6 includes two fixing boxes 8 fixedly installed inside the ladle wall 2. A support frame 9 is slidably connected inside the fixing box 8.

The guide rod 38 can be made of elastic plastic material, so that it can limit and guide the adjacent ladle wall 2 while having a certain elasticity, improving the vibration damping efficiency. The guide rod 38 penetrates through the side plate 4 at the other end of the connecting spring 5 and is slidably connected to the inner wall of the side plate 4.

[0022] The adjusting member 7 includes a fixing ring 19 installed above the bottom plate 1. Four guide frames 20 are fixedly connected to the side surface of the fixing ring 19. A guide block 21 is fixedly connected to the side surface of the ladle wall 2. The guide block 21 is slidably connected to the inner wall of the guide frame 20.

A driving member 23 for synchronously driving a plurality of second threaded rods 22 to rotate is provided on the fixing ring 19. The driving member 23 includes a bevel gear ring 24 rotatably connected to the outer wall of the fixing ring 19. A bevel gear 25 meshing with the bevel gear ring 24 is coaxially fixedly connected to one end of the second threaded rod 22. A driving ring 26 is fixedly connected to the side surface of the bevel gear ring 24.

[0023] The vibration damping mechanism 3 further includes a threaded box 27 fixedly installed above the bottom plate 1. A threaded cylinder 28 is threadedly connected in the threaded box 27. The threaded cylinder 28 is used for storing damping liquid. A damping plate 29 is slidably connected in the threaded cylinder 28. A plurality of communication holes 39 are provided in the damping plate 29. A damping rod 30 is fixedly connected to the damping plate 29. The damping rod 30 penetrates through the top end of the threaded cylinder 28 and is slidably connected to the threaded cylinder 28. A universal rotating shaft 31 is fixedly connected to the lower ladle wall 2. The top end of the damping rod 30 is connected to the universal rotating shaft 31. A threaded groove 37 capable of being threadedly connected to the threaded cylinder 28 is provided at the top end of the mounting box 14.

[0024] Steel ears 32 are respectively fixedly connected to both sides of the ladle wall 2. A rotating rod 33 is rotatably connected to the steel ears 32. Two fixing plates 34 are fixedly connected to the bottom plate 1. A second spring 35 is fixedly connected to the upper side of the fixing plate 34. The top end of the second spring 35 is fixedly connected to a rotating frame 36. The bottom end of the rotating rod 33 is rotatably connected to the rotating frame 36.

[0025] In this implementation plan, first, it is necessary to inspect and measure the 16 conveying pipes to be installed to determine the installation positions and quantities of the vibration damping devices. At the same time, prepare the required installation tools and materials. Pass the pipe 40 through the middle position of the fixed ring 19, rotate the driving ring 26 to drive the bevel gear ring 24 to rotate. The bevel gear ring 24 drives the four bevel gears 25 to rotate synchronously, so that the second threaded rod 22 drives the guide block 21 to slide in the guide frame 20, synchronously changing the positions of the four ladle walls 2, and making the four ladle walls 2 move and clamp towards the outer wall side of the pipe 40 synchronously. The two rollers 10 on the ladle wall 2 abut against the outer wall of the pipe 40. As the ladle wall 2 continues to move, the roller 10 drives the support frame 9 to slide in the fixed box 8, compressing the damping liquid and the first spring 12 in the fixed box 8. After stopping rotating the driving ring 26, rotate the first threaded rod 18 to make the driving plate 17 slide in the storage cavity 15, compressing the damping liquid until the pressure in the storage cavity 15 reaches the required value, indicating that the clamping and fixing of the pipe 40 is completed.

[0026] When the pipe 40 vibrates, the vibration will be first transmitted to the roller 10. Since the multiple fixed boxes 8 are connected by the connecting pipe 11, when the pipe 40 jitters to one side, the damping liquid will be conveyed to the position on the other side through the connecting pipe 11. In this way, while damping the vibration, the tight clamping of the outer wall of the pipe 40 can always be ensured. The vibration received by the pipe 40 will be preliminarily damped by the damping liquid in the fixed box 8, cutting down all-round some fine vibrations. For some larger vibrations, they will be transmitted to the ladle wall 2 and further damped through the connecting spring 5. The vibrations along the horizontal radial direction of the pipe 40 will be transmitted to the steel ears 32 on both sides, and then transmitted to the rotating frame 36 through the rotating rods 33 on both sides, and damped by the swinging of the second spring 35. The vibrations along the vertical radial direction of the pipe 40 will be transmitted to the damping rod 30 through the universal rotating shaft 31, driving the damping plate 29 to rise and fall in the threaded cylinder 28. During the rising and falling process of the damping plate 29, the damping liquid will slowly flow through the communication hole 39. Since the size of the damping hole is small and the flow rate of the damping liquid is slow, it can damp some rapid large vibrations and improve the stability of the pipe 40. The vibrations along the axial direction of the pipe 40 can also make the ladle wall 2 swing through the universal rotating shaft 31, and the damping and reset operations are realized through the swinging and compression of the second springs 35 on both sides.

[0027] When it is necessary to synchronously reduce vibration of multiple groups of pipes 40, the threaded barrel 28 at the bottom end of another group of vibration reduction devices can be connected to the threaded groove 37 at the upper end of the currently installed vibration reduction device to achieve combined use between devices and improve the flexibility of the use process. After the installation is completed, the vibration reduction device is adjusted and tested to check whether the vibration reduction device is firmly installed and whether each component is working properly. The vibration reduction effect and stability of the device can be verified through simulated vibration or impact tests. After the vibration reduction device is working normally, start the conveying pipeline system and perform daily maintenance. Regularly check the working status of the vibration reduction device to ensure its normal operation and repair or replace damaged parts in time.

[0028] When dismantling is required, the first threaded rod 18 is rotated in the opposite direction to drive the driving plate 17 to slide in the opposite direction, and the damping fluid in the connecting pipe 11 and the fixing box 8 is pumped into the storage chamber 15, thereby reducing the resistance strength of the roller 10 to the outer wall of the pipe 40. Then, the driving ring 26 is rotated in the opposite direction to make the bevel gear ring 24 drive the bevel gear 25 to rotate in the opposite direction, and the second threaded rod 22 can be used to synchronously drive the multiple groups of guide blocks 21 and the ladle wall 2 to slide in all directions and synchronously move away from the pipe 40. Then, the pipe 40 can be pulled out to complete the dismantling operation.

[0029] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0030] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
