Description

Technical Field

[0001] This application relates to the technical field of earthquake resistance, and in particular to a novel annular tension energy-dissipating vibration damper. Background Technology

[0002] During earthquakes, strong vibrations often cause water pipe bursts, gas pipeline damage, and other issues, affecting industrial and agricultural production, residents' lives, and wasting resources. To protect the safe operation of pipeline networks, vibration dampers are typically installed on pipelines for vibration reduction and isolation in various public and civil building piping systems, as well as other industrial pipelines.

[0003] Chinese patent CN102221062A discloses a metal-rubber damping shock absorber, comprising an upper structure and a lower structure. The lower structure consists of a lower base, a lower outer guide cylinder, and a lower inner guide cylinder. The lower outer guide cylinder and the lower inner guide cylinder are connected to the lower base, and a ring-shaped metal-rubber material is disposed between the lower outer guide cylinder and the lower inner guide cylinder. The upper structure consists of an upper base, an upper outer guide cylinder, and an upper inner guide cylinder, which are connected to the upper base. The shock absorption effect can reach 50%-80%.

[0004] Vibration dampers in related technologies reduce pipeline vibration through the buffering and damping effects of rubber materials. Therefore, a certain specification of rubber material is adapted to a certain seismic frequency. When the seismic frequency experienced by the pipeline changes, a rubber material that matches the seismic frequency must be selected. This can easily lead to low adaptability of the vibration damper and affect the pipeline vibration reduction effect. Summary of the Invention

[0005] In order to adapt to different vibration frequencies and reduce the damage of external vibration to the normal operation of pipelines, this application provides a novel annular tension-type energy-dissipating vibration damper.

[0006] This application provides a novel annular tension-type energy-dissipating vibration damper using the following technical solution:

[0007] A novel annular tension-type energy-dissipating vibration damper includes a rubber vibration isolation pad sleeved on the outside of a pipe. Two semi-annular frames, joined together to form a ring, are provided on the outside of the rubber vibration isolation pad. A rotating component connecting the two semi-annular frames is located at the same end, and a fixing component is located at the other end of each semi-annular frame. One semi-annular frame contains a first tuned dynamic vibration absorption component parallel to the length of the pipe and a second tuned dynamic vibration absorption component perpendicular to the pipe. The first tuned dynamic vibration absorption component is located on the side of the semi-annular frame closer to the rotating component. The other semi-annular frame contains a first tuned dynamic vibration absorption component with the same structure as the first tuned dynamic vibration absorption component and located close to the fixing component, and a second tuned dynamic vibration absorption component with the same structure as the second tuned dynamic vibration absorption component and located close to the rotating component.

[0008] By adopting the above technical solution, when subjected to vibrations caused by an earthquake, the first and second tuned dynamic vibration absorption components absorb the earthquake force and adjust the earthquake frequency. The rubber vibration isolation pad plays a vibration isolation role. The two semi-ring frames absorb the same amount of energy, thereby reducing the possibility of uneven vibration of the semi-ring frames and reducing the possibility of the pipeline inside the rubber vibration isolation pad being subjected to earthquake force and vibration. This adapts to different vibration frequencies and reduces the damage of external vibration to the normal operation of the pipeline.

[0009] Optionally, the first tuned dynamic vibration absorption assembly includes a first track disposed inside the semi-annular frame and parallel to the length direction of the pipe. A first vibrator perpendicular to the first track is sleeved and slidably connected on the first track. Both ends of the first vibrator perpendicular to the length direction of the first track are fixedly connected to a first spring. The ends of the first springs that are far apart from each other are fixedly connected to the inner sidewall of the semi-annular frame.

[0010] By adopting the above technical solution, the first oscillator slides along the first track under the seismic force, thereby absorbing the energy generated by the earthquake. The first spring is also subjected to the seismic force and vibrates. While adjusting the seismic frequency of the first oscillator so that the first oscillator resonates with the earthquake, it also plays a damping role through its own elastic potential energy, reducing the possibility of vibration of the pipe inside the rubber vibration isolation pad. This adapts to different seismic frequencies and reduces the adverse effects on the vibration reduction effect of the pipe.

[0011] Optionally, two first springs are fixedly connected to the ends of the first oscillator. The ends of the two first springs located at the same end of the first oscillator that are away from the first oscillator are inclined in a direction away from each other and fixedly connected to the inner sidewall of the semi-ring frame.

[0012] By adopting the above technical solution, the first spring is inclined at the end of the first oscillator, which facilitates the adjustment of the seismic frequency received by the first oscillator, so that the first oscillator resonates with the seismic frequency and absorbs the seismic energy, further reducing the possibility of vibration on the pipe inside the rubber vibration isolation pad, thereby adapting to different vibration frequencies and reducing the damage of external vibration to the normal operation of the pipeline.

[0013] Optionally, the second tuned dynamic vibration absorption assembly includes an arc-shaped second track perpendicular to the length of the pipe and adapted to the outer wall of the pipe. A second vibrator parallel to the length of the second track is sleeved and slidably connected on the second track. Two second springs are fixedly connected to the ends of the second vibrators. The ends of the second springs away from the second vibrators are inclined toward each other and fixedly connected to the inner wall of the semi-annular frame.

[0014] By adopting the above technical solution, when the second oscillator is subjected to vibrations caused by an earthquake, it slides along the second track and absorbs energy. At this time, the second spring adjusts the earthquake frequency of the second oscillator and makes the second oscillator resonate with the earthquake. The sliding direction of the first oscillator is perpendicular to the sliding direction of the second oscillator, thereby reducing the possibility of the first and second oscillators sliding simultaneously and causing semi-circular frame vibration. This further reduces the possibility of the pipe inside the rubber vibration isolation pad being subjected to vibration, thereby adapting to different vibration frequencies and reducing the damage of external vibration to the normal operation of the pipeline.

[0015] Optionally, the rotating component includes two rotors disposed at one end of the semi-ring frame that are close to each other and corresponding to the semi-ring frame. One end of one rotor away from the corresponding semi-ring frame abuts against the side of the other rotor away from the corresponding semi-ring frame that is away from the rubber vibration isolation pad. The ends of the rotors that abut against each other are simultaneously connected to a bolt that passes through and rotates, and one end of the bolt is threaded with a nut.

[0016] By adopting the above technical solution, when installing the semi-ring frame, tightening the nut and driving the semi-ring frame to rotate in the direction away from each other along the bolts makes it easier to fit onto the outside of the pipe and improves installation efficiency.

[0017] Optionally, the fixing assembly includes a first fixing member disposed at one end of one of the semi-ring frames away from the rotor and a second fixing member corresponding to the other semi-ring frame. The first fixing member and the second fixing member cooperate with each other. The first fixing member includes a housing fixedly connected to the corresponding semi-ring frame and a hook tongue rotatably connected to the housing. The second fixing member also includes a housing fixedly connected to the corresponding semi-ring frame. The housing of the second fixing member is also rotatably connected to a hook tongue. When the semi-ring frames are connected to each other through the first fixing member and the second fixing member, the hook tongue on the first fixing member and the hook tongue on the second fixing member engage with each other. The housing is provided with a snap-fit ​​member for fixing the hook tongue.

[0018] By adopting the above technical solution, when the semi-ring frame is fixed on the outside of the pipe, the hook tongues move towards each other until the hooks are engaged. At this time, the engaging parts make it difficult for the hook tongues to rotate on the shell, thereby fixing the position of the hook tongues and making it easier to fix the semi-ring frame on the pipe, thus improving installation efficiency.

[0019] Optionally, the snap-fit ​​component includes two snap-fit ​​rods perpendicular to the length of the pipe, each corresponding to the hook tongue and located on the side of the hook tongue away from each other. The end of the snap-fit ​​rod away from the pipe is inserted into the housing and slidably connected to the housing. Each snap-fit ​​rod is provided with a limiting plate on the side near the corresponding hook tongue. The limiting plate is located on the upper side of the corresponding hook tongue. When the hook tongues snap together, the side wall of the snap-fit ​​rod abuts against the side wall of the corresponding hook tongue, and the limiting plate abuts against the upper side of the corresponding hook tongue.

[0020] By adopting the above technical solution, the drive clamping rod moves upward. At this time, the limiting plate on the clamping rod disengages from the hook tongue, and the hook tongue can rotate. When the hook tongues are engaged with each other, the drive clamping rod moves downward until the limiting plate abuts against the upper side of the hook tongue, and the bolt is tightened. At this time, the semi-ring frame is fixed to each other, which makes it easier to install the semi-ring frame on the pipeline and improves the installation efficiency.

[0021] Optionally, an adjustment assembly is provided between the rotor and the corresponding semi-ring frame. The adjustment assembly includes an adjustment frame fixedly connected to one end of the semi-ring frame near the rotor. The adjustment frame and the end of the corresponding semi-ring frame form a cavity. An adjustment plate is provided in the cavity, with its sidewall abutting against and slidably connected to the sidewall of the adjustment frame. A fourth spring is provided on the side of the adjustment plate and the semi-ring frame that are close to each other, connecting the two. The ends of the rotor that are far apart from each other pass through the adjustment frame and are fixedly connected to the sidewall of the adjustment plate. Screws with ends abutting against the adjustment plate are inserted and threaded onto the side of the adjustment frame that are close to each other.

[0022] By adopting the above technical solution, the length of the adjusting screw inserted into the adjusting frame is adjusted, thereby adjusting the position of the adjusting plate in the cavity, thereby adjusting the length of the rotor outside the adjusting frame, so that the semi-ring frame can adapt to the size of pipes with different diameters.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When subjected to vibrations caused by an earthquake, the first and second tuned power vibration absorption components absorb the earthquake force and adjust the earthquake frequency. The rubber vibration isolation pad plays a vibration isolation role. The two semi-ring frames absorb the same amount of energy, thereby reducing the possibility of uneven vibration of the semi-ring frames and reducing the possibility of the pipe inside the rubber vibration isolation pad being subjected to earthquake force and vibration. This adapts to different vibration frequencies and reduces the damage of external vibration to the normal operation of the pipeline.

[0025] 2. The first spring is inclined at the end of the first oscillator, which facilitates the adjustment of the seismic frequency received by the first oscillator, so that the first oscillator resonates with the seismic frequency and absorbs the seismic energy, further reducing the possibility of vibration on the pipe inside the rubber vibration isolation pad, thereby adapting to different vibration frequencies and reducing the damage of external vibration to the normal operation of the pipeline.

[0026] 3. When the second oscillator is subjected to vibrations caused by an earthquake, it slides along the second track and absorbs energy. At this time, the second spring adjusts the earthquake frequency of the second oscillator and makes the second oscillator resonate with the earthquake. The sliding direction of the first oscillator is perpendicular to the sliding direction of the second oscillator, thereby reducing the possibility of the first and second oscillators sliding simultaneously and causing semi-circular frame vibration. This further reduces the possibility of the pipe inside the rubber vibration isolation pad being subjected to vibration, thus adapting to different vibration frequencies and reducing the damage of external vibration to the normal operation of the pipeline.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] This application discloses a novel annular tension-type energy-dissipating vibration damper. (Refer to...) Figure 1 and Figure 2 A novel annular tension-type energy-dissipating vibration damper includes an annular rubber vibration isolation pad 1 sleeved on the outside of a pipe. On the side of the rubber vibration isolation pad 1 away from the pipe, there are two semi-annular frames 2 spliced ​​together to form an annular shape. The semi-annular frames 2 include two semi-annular and vertical first side plates 21. The same vertical second side plate 22 is fixedly connected to the same end of the first side plate 21, and the same vertical second side plate 22 is also fixedly connected to the other end of the first side plate 21. The same horizontal second side plate 22 is also fixedly connected to the middle of the first side plate 21 and the side of the first side plate 21 that is close to each other.

[0035] Reference Figure 2 and Figure 3 The upper end of the semi-ring frame 2, on both sides close to each other, is provided with the same rotating component 3 connecting the two components, and the lower end of the semi-ring frame 2, on both sides close to each other, is provided with the same fixing component 4 connecting the two components. Inside one of the semi-ring frames 2, there is a first tuning dynamic vibration absorption component 5 located at the upper end of the semi-ring frame 2 and a second tuning dynamic vibration absorption component 6 located away from the rotating component 3. Inside the other semi-ring frame 2, there is a second tuning dynamic vibration absorption component 6 with the same structure as the second tuning dynamic vibration absorption component 6 and located close to the rotating component 3, and a first tuning dynamic vibration absorption component 5 located close to the fixing component 4 and with the same structure as the first tuning dynamic vibration absorption component 5.

[0036] The rubber vibration isolation pad 1 is fitted onto the outside of the pipe. The rotating component 3 drives the two semi-ring frames 2 to roll away from each other until both semi-ring frames 2 are positioned on both sides of the pipe and abut against the sidewalls of the rubber vibration isolation pad 1. At this point, the two semi-ring frames 2 are fixed by the fixing component 4. When subjected to vibrations caused by an earthquake, the first tuned dynamic vibration absorption component 5 and the second tuned dynamic vibration absorption component 6 absorb the received seismic force and adjust the seismic frequency. The rubber vibration isolation pad 1 then acts as a vibration isolation device. Since the two semi-ring frames 2 absorb the same amount of energy, the possibility of uneven vibration of the semi-ring frames 2 outside the pipe is reduced, achieving both vibration reduction and isolation effects.

[0037] Reference Figure 2 and Figure 3 The rotating component 3 includes two horizontal rotors 31 corresponding to the semi-annular frame 2. Both rotors 31 are located in the same horizontal plane parallel to the length of the pipe, and the ends of the rotors 31 away from the corresponding semi-annular frame 2 overlap each other. The overlapping ends of the rotors 31 are each connected to a bolt 32 through which a nut (not shown in the figure) is threaded.

[0038] When installing the semi-ring frame 2, tighten the nut and drive the semi-ring frame 2 to rotate away from each other with the bolt 32 as the axis, and fit it on the outside of the rubber vibration isolation pad 1. At this time, tighten the nut and fix the semi-ring frame 2 through the fixing component 4 to complete the installation of the semi-ring frame 2.

[0039] Reference Figure 2 and Figure 4 The first tuned dynamic vibration absorption assembly 5 includes two first tracks 51 located in the same vertical plane and perpendicular to the length direction of the first side plate 21. Each first track 51 has a first vibrator 52 sleeved and slidably connected to it, perpendicular to the first track 51. The first vibrator 52 is configured as an arc shape adapted to the outer wall of the pipe, and each end of the first vibrator 52 is fixedly connected to two first springs 53 symmetrically arranged along the length direction of the first vibrator 52. The first springs 53 are configured as negative stiffness springs. The ends of the two first springs 53 located at the same end of the first vibrator 52, away from the first vibrator 52, are inclined in a direction away from each other, and the ends of the first springs 53 at the ends of the first vibrator 52, away from the first vibrator 52, are fixedly connected to the inner wall of the second side plate 22.

[0040] After the first oscillator 52 is subjected to the seismic force, it slides along the first track 51 and absorbs the energy generated by the earthquake. At this time, the first spring 53 adjusts the earthquake frequency and makes the first oscillator 52 resonate with the earthquake. The first spring 53 also plays a damping role through its own elastic potential energy, reducing the possibility of vibration of the pipe inside the rubber vibration isolation pad 1, thereby adapting to different earthquake frequencies.

[0041] Furthermore, the first spring 53 is inclined at the end of the first oscillator 52, which facilitates driving the first oscillator 52 to slide on the first track 51 and absorb energy, reducing the possibility of vibration on the pipe inside the rubber vibration isolation pad 1.

[0042] Reference Figure 2 and Figure 4 The second tuned dynamic vibration absorption assembly 6 includes a second track 61 perpendicular to the length of the pipe. The second track 61 is set in an arc shape adapted to the outer wall of the pipe. A second vibrator 62 parallel to the length of the second track 61 is sleeved and slidably connected on the second track 61. Two second springs 63 are also fixedly connected to the ends of the second vibrator 62. The second springs 63 are negative stiffness springs. The ends of the second springs 63 located at the same end of the second vibrator 62 that are away from the second vibrator 62 are all inclined in a direction away from each other and fixedly connected to the inner wall of the second side plate 22.

[0043] When the second oscillator 62 is subjected to earthquake vibration, it slides along the second track 61, thereby absorbing energy through the movement of the second oscillator 62. At the same time, the second spring 63 adjusts the earthquake frequency of the second oscillator 62 and makes the second oscillator 62 resonate with the earthquake. The sliding direction of the first oscillator 52 is perpendicular to the sliding direction of the second oscillator 62, reducing the possibility of the semi-ring frame 2 vibrating due to the simultaneous sliding of the first oscillator 52 and the second oscillator 62.

[0044] Reference Figure 2 and Figure 5 The fixing component 4 includes a first fixing member 41 disposed at the lower end of one of the semi-ring frames 2 and a second fixing member 42 disposed at the lower end of the other semi-ring frame 2. The first fixing member 41 and the second fixing member 42 are both located on the side of the semi-ring frame 2 that are close to each other and cooperate with each other. The first fixing member 41 and the second fixing member 42 are located in the same horizontal plane. The first fixing member 41 and the second fixing member 42 have the same structure, and the second fixing member 42 is obtained by rotating the first fixing member 41 by 180°.

[0045] The first fixing member 41 includes a housing 411 fixedly connected to the lower end of one of the semi-annular frames 2. A receiving groove 4111 is provided at the end of the housing 411 away from the corresponding semi-annular frame 2. A hook tongue 412, rotatably connected to the housing 411, is provided in the receiving groove 4111. A third spring (not shown in the figure) is provided in the receiving groove 4111, located on the side of the hook tongue 412 near the corresponding semi-annular frame 2, with one end fixedly connected to the side wall of the housing 411. The other end of the third spring is fixedly connected to the end of the hook tongue 412. When the third spring is at its original length, the end of the hook tongue 412 connected to the third spring is located outside the receiving groove 4111.

[0046] The hook tongue 412 is provided with a snap-fit ​​groove 4121 on the side away from the corresponding housing 411. When the semi-ring frame 2 is fixed to each other by the first fixing member 41 and the second fixing member 42, the end of the hook tongue 412 of the first fixing member 41 is inserted into the snap-fit ​​groove 4121 of the hook tongue 412 of the second fixing member 42, and the end of the hook tongue 412 of the second fixing member 42 is inserted into the snap-fit ​​groove 4121 on the hook tongue 412 of the first fixing member 41. Both the housing 411 of the first fixing member 41 and the second fixing member 42 are provided with snap-fit ​​members 7 for fixing the hook tongue 412.

[0047] Reference Figure 2 and Figure 5The latching component 7 includes a vertical latching rod 71 located above the housing 411. The lower end of the latching rod 71 is inserted into the housing 411 and slidably connected to the side wall of the housing 411. All latching rods 71 ​​are located on the side of the hook tongues 412 that are far apart from each other. The end of the latching rod 71 that is close to the corresponding hook tongue 412 and inserted into the housing 411 is fixedly connected to two horizontal limiting plates 72. The limiting plates 72 are located in the same vertical plane, and the distance between the limiting plates 72 on the same latching rod 71 is greater than the height of the end of the hook tongue 412 that is connected to the third spring. A fixing groove 4122 adapted to the limiting plate 72 is opened on the upper side of the end of the hook tongue 412 that is connected to the third spring. When the hook tongues 412 are latched together, the limiting plate 72 on the upper side of the hook tongue 412 is inserted into the fixing groove 4122, and the hook tongue 412 is fixed at this time.

[0048] When the first fixing member 41 and the second fixing member 42 are not engaged, the third spring causes the end of the hook tongue 412 near the third spring to be located outside the receiving groove 4111, driving the locking rod 71 to move upward until the limiting plate 72 on the upper side of the locking rod 71 is no longer in contact with the hook tongue 412. At this time, the hook tongue 412 can rotate.

[0049] During the process of fitting the semi-ring frame 2 onto the outside of the pipe and the outer wall of the rubber vibration isolation pad 1, the housing 411 drives the hook tongue 412 to move closer to each other. At this time, the end of the hook tongue 412 of the first fixing member 41 away from the corresponding third spring gradually approaches the side of the hook tongue 412 of the second fixing member 42 that is close to the corresponding third spring, and the end of the hook tongue 412 of the second fixing member 42 away from the corresponding third spring gradually approaches the side of the hook tongue 412 of the first fixing member 41 that is close to the corresponding third spring, until the ends of the hook tongues 412 on the first fixing member 41 and the second fixing member 42 that are close to the third spring are both rotated into the corresponding receiving groove 4111 under compression. At this time, the ends of the hook tongues 412 away from the third spring are both engaged in the engaging groove 4121 on the other hook tongue 412.

[0050] Drive the locking rod 71 to move downward until the limiting plate 72 on the upper side of the locking rod 71 is inserted into the fixing groove 4122 on the hook tongue 412. At this time, the side wall of the locking rod 71 abuts against the side wall of the hook tongue 412, thereby connecting the lower end of the semi-ring frame 2. Then tighten the bolt 32 at the upper end of the semi-ring frame 2 to complete the fixing of the semi-ring frame 2.

[0051] Reference Figure 2 and Figure 3An adjusting assembly 8 is provided between the rotor 31 and the corresponding semi-ring frame 2 to adjust the inner diameter of the ring formed by the two semi-ring frames 2. The adjusting assembly 8 includes an adjusting frame 81 fixedly connected to the second side plate 22 at the end of the semi-ring frame 2 near the rotor 31. The opening of the adjusting frame 81 faces away from the rotor 31, and the adjusting frame 81 and the second side plate 22 form a cavity 811. A vertical adjusting plate 82 is provided in the cavity 811. The side walls of the adjusting plate 82 are slidably connected to the inner side wall of the adjusting frame 81, and the two ends of the adjusting plate 82 away from the rotor 31 are fixedly connected to a fourth spring 83 in a compressed state. The end of the fourth spring 83 away from the adjusting plate 82 is fixedly connected to the corresponding second side plate 22.

[0052] The end of the rotor 31 closest to the corresponding semi-ring frame 2 is inserted into the adjusting frame 81 and fixedly connected to the middle of the adjusting plate 82 on the side away from the fourth spring 83. Both ends of the adjusting frame 81 closest to the rotor 31 are threaded with screws 84, and the ends of the screws 84 inserted into the adjusting frame 81 abut against the side wall of the adjusting plate 82.

[0053] When adjusting the length of the rotor 31 outside the adjusting frame 81 to adjust the inner diameter of the ring formed by the semi-ring frame 2, the screw 84 is rotated and the length of the screw 84 inserted into the adjusting frame 81 is adjusted. At this time, the adjusting plate 82 in the adjusting frame 81 moves towards or away from the outside of the adjusting frame 81 under the drive of the fourth spring 83 and the screw 84, thereby adjusting the length of the rotor 31 fixedly connected to the adjusting plate 82 outside the adjusting frame 81.

[0054] The implementation principle of a novel annular tension energy-dissipating vibration damper in this application embodiment is as follows: Tighten the nut and drive the semi-annular frame 2 to rotate away from each other with the bolt 32 as the axis, and sleeve it on the outside of the rubber vibration isolation pad 1. At this time, the hook tongues 421 press against each other and rotate along the rotation point until the end of the hook tongue 412 away from the third spring is engaged in the engagement groove 4121 on the other hook tongue 412. Drive the engagement rod 71 to move downward until the limiting plate 72 on the upper side of the engagement rod 71 is inserted into the fixing groove 4122 on the hook tongue 412. At this time, the side wall of the engagement rod 71 abuts against the side wall of the hook tongue 412, tightening the bolt 32 at the upper end of the semi-annular frame 2, and completing the fixation of the semi-annular frame 2.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.

One of the semi-ring frames (2) has a first tuning power vibration absorption component (5) parallel to the length of the pipe and a second tuning power vibration absorption component (6) perpendicular to the pipe. The first tuning power vibration absorption component (5) is located on the side of the semi-ring frame (2) close to the rotating component (3). The other semi-ring frame (2) has a first tuning power vibration absorption component (5) with the same structure as the first tuning power vibration absorption component (5) and close to the fixing component (4) and a second tuning power vibration absorption component (6) with the same structure as the second tuning power vibration absorption component (6) and close to the rotating component (3). The first tuned dynamic vibration absorption assembly (5) includes a first track (51) disposed inside the semi-ring frame (2) and parallel to the length direction of the pipe. A first vibrator (52) perpendicular to the first track (51) is sleeved and slidably connected on the first track (51). Both ends of the first vibrator (52) perpendicular to the length direction of the first track (51) are fixedly connected to a first spring (53). The ends of the first springs (53) that are far apart from each other are fixedly connected to the inner sidewall of the semi-ring frame (2). Two first springs (53) are fixedly connected to the ends of the first oscillator (52). The ends of the two first springs (53) located at the same end of the first oscillator (52) are inclined in a direction away from each other and fixedly connected to the inner wall of the semi-ring frame (2). The second tuned dynamic vibration absorption assembly (6) includes an arc-shaped second track (61) perpendicular to the length direction of the pipe and adapted to the outer wall of the pipe. A second vibrator (62) parallel to the length direction of the second track (61) is sleeved and slidably connected on the second track (61). Two second springs (63) are fixedly connected to the ends of the second vibrator (62). The ends of the second springs (63) away from the second vibrator (62) are inclined in a direction away from each other and fixedly connected to the inner wall of the semi-annular frame (2). The rotating component (3) includes two rotors (31) located at one end of the semi-ring frame (2) that are close to each other and corresponding to the semi-ring frame (2). One end of the rotor (31) away from the corresponding semi-ring frame (2) abuts against the side of the other rotor (31) away from the corresponding semi-ring frame (2) away from the rubber vibration isolation pad (1). The ends of the rotors (31) that abut against each other are simultaneously connected to bolts (32) that pass through and rotate. One end of the bolts (32) is threaded with a nut. The fixing component (4) includes a first fixing member (41) disposed at one end of one of the semi-ring frames (2) away from the rotor (31) and a second fixing member (42) corresponding to the other semi-ring frame (2). The first fixing member (41) and the second fixing member (42) cooperate with each other. The first fixing member (41) includes a housing (411) fixedly connected to the corresponding semi-ring frame (2) and a hook tongue (412) rotatably connected to the housing (411). The second fixing member (42) also includes a hook tongue (412) rotatably connected to the corresponding semi-ring frame (2). The housing (411) is fixedly connected to the corresponding semi-ring frame (2). The housing (411) of the second fixing member (42) is also rotatably connected with a hook tongue (412). When the semi-ring frame (2) is connected to each other through the first fixing member (41) and the second fixing member (42), the hook tongue (412) on the first fixing member (41) and the hook tongue (412) on the second fixing member (42) are engaged with each other. The housing (411) is provided with a snap-fit ​​member (7) for fixing the hook tongue (412). The snap-fit ​​component (7) includes two snap-fit ​​rods (71) that are perpendicular to the length of the pipe and are respectively opposite to the hook tongue (412) and located on the side away from the hook tongue (412). The end of the snap-fit ​​rod (71) away from the pipe is inserted into the housing (411) and slidably connected to the housing (411). Each snap-fit ​​rod (71) is provided with a limiting plate (72) on the side near the corresponding hook tongue (412). The limiting plate (72) is located on the upper side of the corresponding hook tongue (412). When the hook tongues (412) snap into each other, the side wall of the snap-fit ​​rod (71) abuts against the side wall of the corresponding hook tongue (412), and the limiting plate (72) abuts against the upper side of the corresponding hook tongue (412). An adjustment assembly (8) is provided between the rotor (31) and the corresponding semi-ring frame (2). The adjustment assembly (8) includes an adjustment frame (81) fixedly connected to one end of the semi-ring frame (2) near the rotor (31). The adjustment frame (81) and the end of the corresponding semi-ring frame (2) form a cavity (811). An adjustment plate (82) is provided in the cavity (811) with its side wall abutting against and slidingly connected to the side wall of the adjustment frame (81). The adjustment plate (82) and the semi-ring frame (2) are provided with the same fourth spring (83) connecting the two. The ends of the rotor (31) that are far apart from each other pass through the adjustment frame (81) and are fixedly connected to the side wall of the adjustment plate (82). The sides of the adjustment frame (81) that are close to each other are each threaded with a screw (84) whose end abuts against the adjustment plate (82).
