Description

Technical Field

[0001] This invention belongs to the field of pipeline vibration reduction technology, specifically, it relates to a pipeline elastic vibration reduction support and its construction method. Background Technology

[0002] With the rapid development of urban economic construction, a large number of urban rail transit projects have been launched. Accompanying this challenge is the installation of various electromechanical pipelines and other supporting facilities for rail transit, and the noise and vibration impact on the internal and external environment of buildings during pipeline operation is becoming increasingly prominent. How to properly complete the preliminary design and subsequent treatment and renovation of noise and vibration control for various systems and equipment in modern rail transit construction, achieving harmony between noise control and the social environment and landscape beautification, has become a hot topic in the environmental protection profession of construction engineering in recent years. Pipelines are the main propagation path of vibration, and also the source of vibration. When building components are impacted or in operation, vibration will propagate within the components and their connecting structures, generating vibration noise. As long as the structure is continuous, vibration noise can travel long distances.

[0003] Pipeline vibration damping support system involves adding vibration damping springs or damping pads to supports along the pipeline to absorb the vibration and impact energy of the pipeline and achieve the purpose of vibration reduction to the maximum extent.

[0004] For pipe hangers that are far from load-bearing walls and need to be suspended from load-bearing floors, suspension rods are usually used to suspend them from the load-bearing structure. At the same time, shock-absorbing components are installed on the suspension rods. Although this method can provide some shock absorption for the pipes, since the pipes are mainly supported by the connection between the top of the suspension rod and the load-bearing structure, the lower end of the suspension rod is relatively free, making it difficult to avoid the swaying of the suspension rod. The swaying of the suspension rod will affect the stability of the connection between the suspension rod and the load-bearing structure, posing a significant safety hazard.

[0005] Furthermore, since the upper end of the suspension rod is usually fixed, it is difficult to install the hanger if the pipe support plate set between the suspension rods is fixed directly. Once the pipe support plate is fixed, it will affect the shock absorption effect of the hanger. Therefore, the existing suspension hanger cannot simultaneously take into account both the shock absorption effect and the structural safety. Summary of the Invention

[0006] To overcome the problems existing in the background art, the present invention provides a pipeline elastic vibration damping support and its construction method, which can take into account both vibration reduction and structural safety. Moreover, the spring vibration damper structure of the present invention can fix the pipeline support plate, so that the suspension support can be smoothly installed while taking into account both vibration reduction effect and safety.

[0007] Therefore, the first objective of this invention is to provide a pipe elastic vibration damping support, which includes a load-bearing rod, two suspension rods, a pipe support plate, and a spring damper; the upper ends of the two suspension rods are connected to the load-bearing rod, and the lower ends are fixedly connected to the pipe support plate.

[0008] The spring shock absorber includes a base plate, an upper plate, two fixing bolts connecting the base plate and the upper plate, a lower spring assembly, an upper spring assembly, two connecting bolts, an upper clamping bolt, a lower clamping bolt, and an adjusting bolt. The lower spring assembly includes spring A and a lower clamping plate, with spring A connected between the base plate and the lower clamping plate. The upper spring assembly includes an upper clamping plate, spring B, and an adjusting plate, with spring B connected between the upper clamping plate and the adjusting plate. The adjusting bolt passes through the upper plate, with its lower end abutting against the upper surface of the adjusting plate. The two connecting bolts connect the upper clamping plate and the lower clamping plate. The upper clamping bolt and the lower clamping bolt are connected to the upper clamping plate and the lower clamping plate respectively, one above the other.

[0009] The pipe support plate is clamped between the upper clamping bolt and the lower clamping bolt.

[0010] Furthermore, the upper clamping bolt and the lower clamping bolt are respectively provided with an upper clamping plate and a lower clamping plate on their opposite sides; the pipe support plate is clamped between the upper clamping plate and the lower clamping plate.

[0011] Furthermore, the upper clamping plate is longer than the lower clamping plate, and both ends of the upper clamping plate are provided with vertically downward limiting plates.

[0012] Furthermore, the suspension rod includes an upper suspension rod and a lower suspension rod, which are connected by an adjusting ring; the top and bottom ends of the adjusting ring are respectively provided with internal threads in opposite directions; the upper suspension rod and the lower suspension rod are respectively threadedly connected to the adjusting ring.

[0013] Furthermore, a spring damper is also connected to the upper suspension rod.

[0014] Furthermore, positioning bolts are provided at both ends of the base plate.

[0015] The second objective of this invention is to provide a construction method for the aforementioned elastic vibration damping support for pipelines, the construction method comprising the following steps:

[0016] (1) First fix the load-bearing rod to the load-bearing floor slab.

[0017] (2) The distance between the two connecting bolts must be greater than the width of the pipe support plate. The bottom plate and the lower spring assembly should be placed below the pipe support plate.

[0018] (3) Place the upper spring assembly above the pipe support plate with the upper clamping bolt and the lower clamping bolt facing each other, and connect the upper clamping plate and the lower clamping plate with two connecting bolts.

[0019] (4) Align the bolt holes on the bottom plate and the top plate and use fixing bolts to connect and fix the bottom plate and the top plate.

[0020] The third objective of this invention is to provide a method for using the elastic vibration damping support for the pipeline, specifically:

[0021] The compression of springs A and B can be adjusted by rotating the adjusting bolts, depending on the usage of the pipe support plate.

[0022] The length of the suspension rod can be adjusted by rotating the mounting plate.

[0023] The beneficial effects of this invention are:

[0024] This invention can balance the shock absorption of the hanger and the safety of the structure. Furthermore, the spring shock absorber structure of this invention can fix the pipe support plate, enabling the suspension hanger to be installed smoothly while ensuring both shock absorption and safety.

[0025] The structure of this invention is not only easy to construct and install, but also has a good shock absorption effect. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and beneficial effects of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are all within the scope of protection of this invention. Example 1

[0030] A type of pipe elastic vibration damping support

[0031] The aforementioned pipe elastic vibration damping support includes a load-bearing rod 1, two suspension rods, a pipe support plate 3, an installation adjustment ring 2, and a spring damper 4.

[0032] The suspension system includes an upper suspension rod 21 and a lower suspension rod 22. The upper end of the upper suspension rod 21 is connected to the load-bearing rod 1, and the lower end of the lower suspension rod 22 is bolted to the pipe support plate 3. The upper suspension rod 21 and the lower suspension rod 22 are connected by an adjusting ring 2. A spring damper 23 is also welded onto the upper suspension rod 21. The top and bottom ends of the adjusting ring 2 are respectively provided with internal threads in opposite directions; the upper suspension rod 21 and the lower suspension rod 22 are respectively threadedly connected to the adjusting ring 2. By setting the threads at the top and bottom ends of the adjusting ring 2 to be reverse threads, the length of the suspension rod can be adjusted. For example, rotating the adjusting ring 2 clockwise lowers the upper suspension rod 21 while simultaneously raising the lower suspension rod 22, bringing the upper and lower suspension rods closer together and shortening the total length of the suspension. Rotating the adjusting ring 2 counterclockwise raises the upper suspension rod 21 while simultaneously lowering the lower suspension rod 22, moving the upper and lower suspension rods further apart and increasing the total length of the suspension. This structure allows for adjustment of the total length of the suspension, facilitating the adjustment and installation of the overall structure of the invention. The spring damper 23 provides shock absorption.

[0033] The spring shock absorber 4 is one of the main design structures of this invention and a key factor in its smooth construction and installation. The spring shock absorber 4 includes a base plate 6, an upper plate 7, two fixing bolts 8 connecting the base plate 6 and the upper plate 7, a lower spring assembly, an upper spring assembly, two connecting bolts 9, an upper clamping bolt 10, a lower clamping bolt 11, and an adjusting bolt 12. The lower spring assembly includes a spring A13 and a lower clamping plate 14, with spring A13 connected between the base plate 6 and the lower clamping plate 14. The upper spring assembly includes an upper clamping plate 15, a spring B16, and an adjusting plate 17, with spring B16 connected between the upper clamping plate 15 and the adjusting plate 17. The two connecting bolts 9 connect the upper clamping plate 15 and the lower clamping plate 14, linking the upper and lower spring assemblies. The upper clamping bolt 10 and the lower clamping bolt 11 are connected to the upper clamping plate 15 and the lower clamping plate 14 respectively, with the upper clamping plate 18 and the lower clamping plate 19 respectively on the opposite sides of the upper clamping bolt 10 and the lower clamping bolt 11; the pipe support plate 3 is clamped between the upper clamping plate 18 and the lower clamping plate 19, and the upper clamping plate 18 and the lower clamping plate 19 are perpendicular to the pipe support plate 3.

[0034] The adjusting bolt 12 passes through the upper plate 7, and its lower end abuts against the upper surface of the adjusting plate 17. By setting the adjusting bolt 12, the compression of springs A13 and B16 can be adjusted by rotating the adjusting bolt 12. For example, rotating the adjusting bolt 12 causes the adjusting plate 17 to move downward, and the adjusting plate 17 presses down on spring B16. Since the height of the suspension rod is basically fixed, that is, the height of the pipe support plate 3 is basically fixed, when spring B16 is compressed, the upper spring assembly generates downward pressure on the pipe support plate 3. At this time, the downward elastic pressure of the upper spring assembly on the pipe support plate 3 is greater than the upward elastic pressure of the lower spring assembly on the pipe support plate 3. That is, the upper spring assembly and the lower spring assembly together generate downward pressure on the pipe support plate 3, which effectively dampens the vibration of the pipe support plate 3. This is similar to the principle that when a swing is swaying, pressing down on the swing reduces the swaying. Furthermore, before clamping the pipe support plate 3, the total length of the upper and lower spring assemblies can be adjusted using the adjusting bolt 12. At this time, since they are not restricted by the pipe support plate 3 (the pipe support plate 3 is not yet clamped), the elastic force of the upper and lower spring assemblies is the same. When the height of the adjusting plate 17 is adjusted using the adjusting bolt 12, the heights of the upper clamping plate 18 and the lower clamping plate 19 will change accordingly, thereby matching the height of the upper clamping plate 18 and the lower clamping plate 19 with the height of the pipe support plate, thus meeting the clamping requirements of the pipe support plate 3. This invention clamps the pipe support plate 3 between the upper and lower spring assemblies, which not only has a better shock absorption effect but also facilitates the construction and installation of this invention.

[0035] Springs A13, B16, and spring damper 23 mounted on the upper suspension rod 21 all provide effective vertical damping for the pipe support plate 3. However, the structure of this invention is not limited to vertical damping. After the pipe support plate 3 is clamped between the upper spring assembly and the lower spring assembly, a vertical tension is generated along the suspension rod. The upper spring assembly, the lower spring assembly, and the spring damper 23 work together to prevent the suspension rod and the pipe support plate 3 from vibrating in the horizontal direction.

[0036] Positioning bolts 24 are provided at both ends of the base plate 6 to fix the base plate to the ground. The design also includes an upper clamping plate 18 longer than the lower clamping plate 19, and vertically downward limiting plates 20 at both ends of the upper clamping plate 18. The positioning bolts 24 fix the spring shock absorber 4, and the limiting plates 20 at both ends of the upper clamping plate 18 act as a horizontal upper limit for the pipe support plate 3, preventing it from swaying left and right. During processing, the length of the upper clamping plate 18 is matched to the width of the pipe support plate 3, and after fixing, the limiting plates 20 abut against both sides of the pipe support plate 3 in the width direction.

[0037] This invention achieves a better shock absorption effect through the combined use of the upper spring assembly, the lower spring assembly, and the spring damper 23. Compared with ordinary spring shock absorbers, the vibration is significantly reduced. In practical use, as long as the verticality of the suspension rod is ensured during installation, even if M24 bolts are used as fixing bolts 24, the service life can reach more than 6 months. Under the same conditions, when using ordinary spring shock absorbers with M24 bolts as fixing bolts 24, the fixing bolts 24 usually become obviously loose and fall off after 10-15 days of use. Subsequently, the vibration of the pipe support plate 3 becomes more and more obvious, and the shock absorption effect gradually deteriorates.

[0038] As a preferred option, a dispersion plate 26 is provided at the bottom of the adjusting bolt to reduce the pressure of the adjusting bolt on the adjusting plate.

[0039] As a preferred embodiment, the top of the upper suspension rod is provided with a countersunk block 25, and a countersunk hole matching the countersunk block 25 is opened on the upper surface of the load-bearing rod 1. The countersunk hole and the countersunk block 25 can prevent the suspension rod from rotating.

[0040] Note that, as is common knowledge, nuts are key to ensuring the stable connection of bolts, and all bolts in this invention are equipped with nuts.

[0041] Example of usage in this embodiment:

[0042] 1. When the pipe support plate 3 vibrates significantly up and down, rotate the adjusting bolt 12 to press down the adjusting plate 17 and apply a downward force to the pipe support plate.

[0043] 2. When it is necessary to adjust the total length of the suspension rod, rotate the installation and adjustment rod clockwise or counterclockwise.

[0044] 3. Adjust the distance between the upper clamping plate 18 and the lower clamping plate 19 by connecting bolt 9.

[0045] 4. When it is necessary to adjust the height of the upper clamping plate 18 and the lower clamping plate 19, the height of the adjusting plate 17 can be adjusted by adjusting the adjusting bolt 12. Example 2

[0046] The construction method of the pipeline elastic vibration damping support in Example 1 specifically includes the following steps:

[0047] (1) First, fix the load-bearing rod 1 to the suspension rod, fix the suspension rod to the pipe support plate 3, and then fix the load-bearing rod 1 to the load-bearing floor slab. After fixing the load-bearing rod 1, try to make the suspension rod perpendicular to the ground.

[0048] (2) According to the position of the pipe support plate 3, place the fixed base plate 6 and the lower spring assembly below the pipe support plate 3. The lower clamping plate 19 should be perpendicular to the pipe support plate 3, and the center line of the lower clamping plate 19 should be aligned vertically with the center line of the pipe support plate 3 as much as possible. Then, fix the base plate 6 with the positioning bolt 24.

[0049] (3) Position the upper clamping plate 18 and the lower clamping plate 19 directly opposite each other, place the upper spring assembly above the pipe support plate 3, and connect the upper clamping plate 15 and the lower clamping plate 14 with two connecting bolts 9.

[0050] (4) Align the bolt holes of the base plate 6 and the upper plate 7, and connect and fix the base plate 6 and the upper plate 7 with fixing bolts 8. The distance between the base plate 6 and the upper plate 7 needs to be adjusted according to the height position of the pipe support plate 3. With the structure of the present invention, the spring shock absorber 4 can still be installed and clamped to the pipe support plate 3 after the position of the pipe support plate 3 is basically fixed.

[0051] (5) After adjustment, adjust the compression length of spring A13 and spring B16 by adjusting bolt 12. After adjustment, tighten the nut on connecting bolt 9 to clamp the pipe support plate 3 with upper clamping plate 18 and lower clamping plate 19.

[0052] (6) During use, the vibration reduction effect can be adjusted by adjusting the height of the adjusting plate 17 according to the vibration of the pipe support plate 3.

[0053] During the adjustment process, adjusting the length of the fixing bolt 8 (the distance between the base plate 6 and the upper plate 7), adjusting the height of the adjusting plate 17, and adjusting the length of the connecting bolt 9 can all adjust the compression of spring A13 and spring B. At the same time, adjusting all three can adjust the height of the upper clamping plate 18 and the lower clamping plate 19.

[0054] Note that after all bolts are secured in the above steps, tighten them with nuts.

[0055] As the main load-bearing component of this invention, the load-bearing rod is connected to the load-bearing structure (such as a load-bearing wall or a load-bearing floor slab). However, since fixing a component to a load-bearing component is a conventional connection method, this invention does not specifically limit the connection method between the load-bearing rod and the load-bearing component. As one optional solution, fixing rods are provided at both ends of the load-bearing rod. The fixing rods are perpendicularly fixed to the load-bearing rod. The connection between the load-bearing rod and the load-bearing component can be achieved by connecting the fixing rods to the load-bearing structure.

[0056] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
