Description

Technical Field

[0001] The present application relates to the technical field of pipeline construction, and in particular to a pipeline seismic isolation device. Background Art

[0002] Pipeline refers to a device connected by pipes, pipe connectors and valves for transporting gas, liquid or fluid with solid particles. In buildings, common pipes can be divided into: drainage pipes, water supply pipes and HVAC pipes.

[0003] Currently, when pipes need to be arranged horizontally inside a building, a number of hangers are usually used to directly connect the pipes to the ceiling, and the hangers support the pipes upward in the vertical direction to ensure the safety of the pipes.

[0004] During the use of pipelines, the material transportation inside the pipelines will cause the pipelines to shake in the radial direction, causing vibrations between the pipelines and the hangers. The vibrations will not only produce loud noises, but will also affect the connection strength between the pipelines and the hangers, as well as the connection strength between the hangers and the buildings, thereby affecting the safety of pipeline use.

[0005] In this regard, there is an urgent need for a pipeline seismic isolation device to reduce the impact of vibration when the pipeline is in use. Utility Model Content

[0006] The present application provides a pipeline seismic isolation device, which can effectively reduce the impact of vibration on the safety of the pipeline during use, and can effectively reduce the noise generated by the vibration.

[0007] The present application provides a pipeline seismic isolation device, which adopts the following technical solution:

[0008] A pipeline seismic isolation device comprises a hanger assembly, a clamping assembly and a plurality of seismic isolation assemblies;

[0009] The hanger assembly comprises a horizontally arranged crossbar, a base is arranged on the crossbar, and the base is located above the crossbar;

[0010] The clamping assembly comprises an upper clamp and a lower clamp, wherein the upper clamp is detachably connected to the lower clamp, and the upper clamp and the lower clamp are connected to each other to embrace and clamp the pipe;

[0011] A plurality of plug-in rods extend outwardly from the lower clamp, and after the clamping assembly clamps the pipe, the extending direction of the plug-in rods is parallel to the axis of the portion of the pipe clamped by the clamping assembly;

[0012] A plurality of the seismic isolation components correspond one to one with a plurality of the plug-in rods. The seismic isolation components are arranged on the base. The seismic isolation components include a seat body and an elastic seismic isolation ring. The seismic isolation ring is arranged on the seat body, and the center of the seismic isolation ring has an insertion space for the corresponding plug-in rod to be inserted. After the plug-in rod is plugged in with the corresponding seismic isolation ring, the inner side of the seismic isolation ring contacts and abuts against the outer side of the plug-in rod.

[0013] By adopting the above technical solution, the pipeline can be fixed in position by the hanger assembly and the clamping assembly. When the pipeline vibrates during use, the pipeline will transfer the vibration to the seismic isolation assembly through the plug-in rod. The seismic isolation assembly reduces the impact of pipeline vibration by deforming the seismic isolation ring under stress, thereby effectively reducing the impact of vibration on the safety of its use during use, and can effectively reduce the noise generated by vibration.

[0014] Optionally, the inner side of the isolation ring has a plurality of inwardly protruding deformation portions, the plurality of deformation portions are distributed in a circular array with the axis of the isolation ring as the axis, and the plurality of deformation portions are in contact with and abut against the corresponding plug-in rods.

[0015] By adopting the above technical solution, when the vibration of the pipeline drives the lower clamp to move, the plug-in rod will squeeze part of the deformed part to cause the isolation ring to undergo elastic deformation. After the isolation ring undergoes elastic deformation, the tendency of pipeline vibration can be reduced, and at the same time, the noise and wear between the clamping assembly and the hanger assembly can be reduced.

[0016] Optionally, the interior of the seismic isolation ring has a closed inner cavity, and the inner cavity is filled with fluid;

[0017] The inner cavity includes a plurality of deformation cavities and a plurality of through cavities. The plurality of deformation cavities are respectively located inside the plurality of deformation parts, and adjacent deformation cavities are connected through the through cavities.

[0018] By adopting the above technical solution, after the deformation part is squeezed and compressed by the plug-in rod, other deformation parts can bulge, so that several deformation parts keep in contact with the plug-in rod, thereby effectively improving the seismic isolation effect of the seismic isolation assembly.

[0019] Optionally, the fluid is an inert gas.

[0020] By adopting the above technical solution, the material reaction between the fluid and the isolation ring can be reduced, thereby effectively extending the service life of the isolation ring.

[0021] Optionally, the fluid is water.

[0022] By adopting the above technical solution, when the seismic isolation ring is affected by the vibration of the pipeline, it will drive the water in the inner cavity to flow, and convert part of the vibration energy into kinetic energy of the water flow, thereby further reducing the impact of the pipeline vibration.

[0023] Optionally, a feed pipe is provided on the seat body, one end of the feed pipe is communicated with the inner cavity, the other end of the feed pipe is located at one side of the seat body, and the end of the feed pipe away from the inner cavity is controllably openable and closable.

[0024] By adopting the above technical solution, it is convenient for the staff to fill or supplement the fluid into the inner cavity, so that the seismic isolation ring has a better seismic isolation effect.

[0025] Optionally, the base has a first mounting groove that is compatible with the lower clamp, and the opening of the first mounting groove is upward; the base is provided with a plurality of clearance grooves that are compatible with the plug-in rod on the groove walls on both sides of the first mounting groove, and a plurality of second mounting grooves that are compatible with the seat body are respectively provided on both sides of the base; the top of the clearance groove passes through the seat body to form an opening, and the bottom of the clearance groove is communicated with the corresponding second mounting groove.

[0026] By adopting the above technical solution, it is convenient for workers to form a connection between the clamping assembly and the hanger assembly, thereby improving the installation efficiency of the pipeline seismic isolation device.

[0027] Optionally, a plurality of universal pulleys are provided on the base, and the universal pulleys are in contact with and abut against the end surface of the lower clamp where the plug-in rod is located.

[0028] By adopting the above technical solution, the friction between the lower clamp and the base can be reduced when the pipeline vibrates and displaces, so that the displacement of the lower clamp relative to the base can be smoother and the noise generated by the friction between the two can be reduced.

[0029] Optionally, the hanger assembly further comprises a plurality of vertically arranged vertical rods with adjustable lengths, and two ends of the vertical rods are respectively connected to the building and the horizontal rods.

[0030] By adopting the above technical solution, the hanger assembly can be easily adapted to different pipeline installation heights, and the installation of the pipeline seismic isolation device can be further facilitated.

[0031] In summary, the present application includes at least one of the following beneficial effects:

[0032] 1. The vibration tendency of the pipeline can be suppressed through the seismic isolation assembly, thereby effectively reducing the impact of the vibration on the safety of the pipeline during use, and effectively reducing the noise generated by the vibration;

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-5 This application is described in further detail.

[0042] Embodiment 1:

[0043] Reference Figure 1 The embodiment of the present application discloses a pipeline seismic isolation device, which can effectively reduce the vibration tendency of the pipeline 6 during use while facilitating the lifting of the pipeline 6, and can also reduce the impact of the vibration of the pipeline 6 on the safety of the use of the pipeline 6, and can also reduce the noise generated by the vibration of the pipeline 6.

[0044] Reference Figure 1 and Figure 2The seismic isolation device for pipelines includes a hanger assembly 1, a clamping assembly 2 and a seismic isolation assembly 3. The hanger assembly 1 is used to hang the pipeline 6 in the building; the clamping assembly 2 is used to fix the installation position of the pipeline 6 so that the pipeline 6 maintains a stable relative position with the hanger assembly 1 after installation; the seismic isolation assembly 3 is used to reduce the tendency of the pipeline 6 to vibrate during use, and can also reduce the impact of the vibration of the pipeline 6.

[0045] The hanger assembly 1 includes a cross bar 11 and a plurality of vertical bars 12 .

[0046] The vertical rod 12 is installed in a vertical state in the indoor space of the building, and the top of the vertical rod 12 is fixedly connected to the ceiling. The bottoms of the plurality of vertical rods 12 are fixedly connected to the cross bar 11, so that the cross bar 11 is installed in a horizontal state below the plurality of vertical rods 12. In this embodiment, the hanger assembly 1 preferably includes two vertical rods 12, and the bottoms of the two vertical rods 12 are fixedly connected to the two ends of the cross bar 11 in the length direction.

[0047] The length of the vertical rod 12 is adjustable along its length direction (i.e., the length of the vertical rod 12 is adjustable along the vertical direction), so that the staff can conveniently adjust the height position of the cross bar 11. In this embodiment, since the length-adjustable setting is a common prior art, the specific method of adjusting the length of the vertical rod 12 is not further limited here, and the accompanying drawings only show one method of adjusting the length of the vertical rod 12 (realized by sleeve-arranging two relatively slidable sleeves and positioning bolts).

[0048] Reference Figure 1 and Figure 2 The top of the middle position of the cross bar 11 has a base 13 for installing the clamping assembly 2, and the base 13 has a first installation groove 131 for facilitating the clamping assembly 2 to determine the installation position. The first installation groove 131 penetrates the base 13 vertically upward and along the length direction of the cross bar 11 to form an opening for facilitating the entry and exit of the clamping assembly 2 for installation.

[0049] The clamping assembly 2 includes an upper clamp 21 and a lower clamp 22, and the upper clamp 21 and the lower clamp 22 are detachably connected, and after the two are connected, they can embrace and clamp the pipe 6. In this embodiment, preferably, a rubber layer 4 is fixedly installed on the end surface of the upper clamp 21 for contacting and abutting the pipe 6 and the end surface of the lower clamp 22 for contacting and abutting the pipe 6, so as to reduce the wear on the surface of the pipe 6 when the clamping assembly 2 clamps the pipe 6; and preferably, the upper clamp 21 and the lower clamp 22 are detachably connected by two bolts. Since the detachable connection by bolts is a common prior art, it will not be described here, and it is only briefly shown in the drawings.

[0050] The first installation groove 131 is used for installing and positioning the lower clamp 22, and the base 13 has a rubber layer 4 fixedly installed on the groove wall at the bottom of the first installation groove 131; after the lower clamp 22 is installed and positioned in the first installation groove 131, the bottom end surface of the lower clamp 22 will contact and abut against the rubber layer 4 on the base 13.

[0051] Reference Figure 2 After the lower clamp 22 is installed and positioned in the center of the first installation groove 131, there is a distance between the two side end surfaces of the lower clamp 22 and the groove wall of the adjacent first installation groove 131. At this time, there is enough space for the lower clamp 22 to move horizontally in the first installation groove 131.

[0052] Reference Figure 2 and Figure 3 , several seismic isolation components 3 are installed on the base 13, and several plug-in rods 221 used in conjunction with the seismic isolation components 3 extend outward on both sides of the lower clamp 22. The lower clamp 22 forms a connection relationship with the seismic isolation components 3 through the plug-in rods 221, and forms a connection relationship with the base 13 through the seismic isolation components 3.

[0053] Reference Figure 1 and Figure 2 , a plurality of plug-in rods 221 correspond one-to-one to a plurality of seismic isolation components 3. In this embodiment, it is preferred that a total of four plug-in rods 221 are provided on the lower clamp 22, and two plug-in rods 221 are respectively provided on both sides of the lower clamp 22, and the two plug-in rods 221 on the same side are respectively close to the two ends of the length direction of the lower clamp 22, and the plug-in rods 221 extend outward in a direction parallel to the axis of the pipe 6 clamped by the clamping component 2.

[0054] Two clearance grooves 132 adapted to the plug-in rod 221 are provided on both sides of the base 13. The clearance grooves 132 are provided in a direction perpendicular to the length direction of the cross bar 11. The clearance grooves 132 pass through the top of the base 13 to form an opening, and the clearance grooves 132 are communicated with the first installation groove 131, so as to facilitate the lower clamp 22 to be installed in and out of the first installation groove 131 along the vertical direction.

[0055] Two second mounting grooves 133 adapted to the seismic isolation assembly 3 are also provided on both sides of the base 13, and the four clearance grooves 132 correspond one to one with the four second mounting grooves 133. One end of the second mounting groove 133 communicates with the bottom of the corresponding clearance groove 132, and the other end communicates with a space on one side of the base 13.

[0056] Reference Figure 2 and Figure 3The seismic isolation assembly 3 is a cylindrical structure as a whole, and the plug rod 221 is a cylindrical structure. When the bottom of the lower clamp 22 contacts and abuts against the rubber layer 4 on the base 13, the plug rod 221 will leave the corresponding clearance groove 132 and enter the corresponding second installation groove 133, and at this time, the axis of the plug rod 221 coincides with the axis of the corresponding second installation groove 133.

[0057] The seismic isolation assembly 3 includes a seat body 31 and a seismic isolation ring 32 .

[0058] The seat body 31 is matched with the second installation groove 133 , and the seat body 31 is detachably connected to the base 13 through a plurality of bolts, so that the seismic isolation component 3 and the base 13 are detachably connected, which makes it convenient for the staff to install and replace the seismic isolation component 3 .

[0059] The seat body 31 and the isolation ring 32 are both hollow cylindrical structures. The seat body 31 and the isolation ring 32 are sleeved and matched, and the isolation ring 32 is fixedly connected to the seat body 31. The isolation ring 32 has an insertion space 33 for the plug-in rod 221 to be inserted therein. After the plug-in rod 221 is inserted into the insertion space 33, the isolation ring 32 and the plug-in rod 221 are sleeved and matched, and the inner side of the isolation ring 32 contacts and abuts against the outer side of the plug-in rod 221.

[0060] The seismic isolation ring 32 has elastic deformation capability. In this embodiment, the seismic isolation ring 32 is preferably made of rubber material. After the pipe 6 is installed on the hanger assembly 1 through the clamping assembly 2, when the pipe 6 vibrates, the vibration trend of the pipe 6 along the radial direction will be transmitted to the seismic isolation ring 32, and the seismic isolation ring 32 can buffer it, absorb part of the vibration, and thus reduce the impact of the vibration of the pipe 6.

[0061] Furthermore, the inner side of the isolation ring 32 has a plurality of deformation parts 321, and the elastic deformation capacity of the deformation parts 321 is better than the elastic deformation capacity of other parts of the isolation ring 32; the isolation ring 32 contacts and abuts against the outer surface of the plug-in rod 221 through the plurality of deformation parts 321, and the plurality of deformation parts 321 are distributed in a circular array on the isolation ring 32 with the axis of the isolation ring 32 as the axis. In this embodiment, it is preferred that the isolation ring 32 has a total of four deformation parts 321.

[0062] The isolation ring 32 has an inner cavity 322 filled with a fluid 34, and the fluid 34 can flow freely in the inner cavity 322. The inner cavity 322 includes a plurality of deformation cavities 3221 and a plurality of through cavities 3222. The plurality of deformation cavities 3221 are distributed in a circular array with the axis of the isolation ring 32 as the axis, and adjacent deformation cavities 3221 are communicated with each other through the through cavities 3222.

[0063] The plurality of deformation cavities 3221 correspond one-to-one to the plurality of deformation parts 321, so in this embodiment, the inner cavity 322 preferably includes four deformation cavities 3221 and four through cavities 3222, and the four deformation cavities 3221 are respectively located inside the four deformation parts 321; and the space size of the deformation cavity 3221 is preferably larger than the space size of the through cavity 3222.

[0064] When the pipeline 6 vibrates in the radial direction, the pipeline 6 will drive the lower clamp 22 to move in the radial direction, causing the plug-in rod 221 to move and squeeze one or two deformation parts 321. After the deformation part 321 is squeezed and deformed, the fluid 34 in the corresponding deformation cavity 3221 will flow through the through cavity 3222 to other deformation cavities 3221, so that the deformation part 321 that has not been squeezed and deformed will bulge, so that it can maintain contact with the outer side of the plug-in rod 221, thereby effectively suppressing the vibration tendency of the pipeline 6 through the elastic deformation recovery ability of the isolation ring 32 to achieve the isolation effect.

[0065] Furthermore, the fluid 34 is preferably a gas and an inert gas, such as nitrogen. Since the intensity of the reaction between the inert gas and other substances is relatively low, the intensity of the material reaction between the inert gas in the inner cavity 322 and the seismic isolation ring 32 is relatively low, which can effectively extend the service life of the seismic isolation ring 32 and reduce the probability of the seismic isolation ring 32 being easily damaged due to the material reaction between the inner cavity and the fluid 34.

[0066] Reference Figure 3 and Figure 4 Furthermore, in order to facilitate the staff to fill or supplement the fluid 34 into the inner cavity 322, a material delivery pipe 35 is fixedly installed on the seat body 31. One end of the material delivery pipe 35 passes through the isolation ring 32 and communicates with the inner cavity 322 (preferably, it communicates with one of the deformation cavities 3221), and the other end of the material delivery pipe 35 is exposed on the outside of the seat body 31 to facilitate the staff to deliver materials.

[0067] When the seismic isolation assembly 3 is installed on the base 13, the end of the feed pipe 35 away from the inner cavity 322 is located on one side of the base 13, and the end of the feed pipe 35 away from the inner cavity 322 has a controllable opening and closing structure. In this embodiment, it is preferred that the structure of the end of the feed pipe 35 away from the inner cavity 322 is the same as the structural principle of the valve core. When it is necessary to fill or replenish the fluid 34 into the inner cavity 322, the opening can be opened so that the fluid 34 can enter the inner cavity 322 through the feed pipe 35; when it is not necessary to fill or replenish the fluid 34 into the inner cavity 322, the opening can be kept closed so that the inner cavity 322 forms a closed space relative to the outside world. Since the structure of the valve core is a common prior art, the structure of the feed pipe 35 is not described in detail here, and the structure of the end of the feed pipe 35 away from the inner cavity 322 is only briefly shown in the attached drawings.

[0068] Reference Figure 1 and Figure 5Furthermore, in order to facilitate the displacement of the lower clamp 22 relative to the base 13 along the radial direction of the pipeline 6 when the pipeline 6 vibrates and reduce the wear between the lower clamp 22 and the base 13, a plurality of universal pulleys 5 can be detachably mounted on the base 13. In this embodiment, preferably, two universal pulleys 5 are mounted on the base 13 (in other embodiments, more universal pulleys 5 can be mounted, but in an even number), and the two universal pulleys 5 are respectively mounted on both sides of the base 13 and symmetrically distributed; and preferably, the universal pulley 5 is detachably connected to the base 13 by a plurality of bolts, so as to facilitate the installation and replacement of the universal pulley 5; since the universal pulley 5 and the method of detachably connecting by bolts are both common prior arts, they will not be described in detail here, and they are only briefly shown in the drawings.

[0069] After the lower clamp 22 is installed on the base 13, the two universal pulleys 5 are respectively fitted and abutted against the end surfaces of the two sides of the lower clamp 22; when the vibration of the pipeline 6 drives the lower clamp 22 to move along the radial direction of the pipeline 6, the lower clamp 22 can be smoothly displaced relative to the base 13 through the universal pulley 5, and the universal pulley 5 can be driven by the lower clamp 22 to rotate in a universal direction.

[0070] The implementation principle of a pipeline seismic isolation device in the embodiment of the present application is:

[0071] When the pipe 6 vibrates during use, the vibration of the pipe 6 will be transmitted to the isolation ring 32 through the plug-in rod 221. The elastic deformation ability of the isolation ring 32 itself can play a buffering role. At the same time, the displacement and extrusion deformation part 321 of the plug-in rod 221 can drive the unextruded deformation part 321 to maintain contact with the plug-in rod 221, thereby suppressing the vibration tendency of the pipe 6 and further reducing the impact of the vibration of the pipe 6. That is, the probability that the vibration of the pipe 6 will affect the connection strength between the pipe 6 and the hanger assembly 1 and affect the safety of use can be reduced, and the noise generated by the vibration of the pipe 6 can also be reduced.

[0072] Embodiment 2:

[0073] The difference between this embodiment and embodiment 1 lies in the fluid 34. In this embodiment, the fluid 34 is preferably water.

[0074] Reference Figure 2 and Figure 3 When the pipe 6 vibrates during use and drives the lower clamp 22 to move, after the plug-in rod 221 squeezes the deformation portion 321, the water in the corresponding deformation cavity 3221 will flow through the through cavity 3222 to the deformation cavity 3221 that is not squeezed.

[0075] The implementation principle of a pipeline seismic isolation device in the embodiment of the present application is:

[0076] When the pipe 6 vibrates, the clamp 22 drives the plug-in rod 221 to squeeze the deformed portion 321 on the isolation ring 32, which will drive the water in the inner cavity 322 to flow, so that part of the energy of the vibration of the pipe 6 will be converted into kinetic energy of the water flowing in the inner cavity 322, so that the isolation ring 32 has a stronger effect of suppressing the vibration of the pipe 6, thereby further reducing the impact of the vibration of the pipe 6.

[0077] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
