Abstract
Description
Technical Field
[0001] This utility model relates to the field of damper technology, and in particular to a flexible damping device. Background Technology
[0002] Damping devices are general-purpose equipment used for pipeline vibration reduction. The most commonly used product is the hydraulic damper. Hydraulic dampers are primarily used to protect pipelines from damage caused by accidental dynamic accidents, ensuring the safe operation of the pipeline system. They play an irreplaceable role in vibration reduction, anti-vibration, and safety protection. Hydraulic dampers mainly rely on the resistance generated by the fluid medium passing through the orifice plate to reduce vibration. During normal pipeline expansion and deformation, the hydraulic damper moves slowly with it, at which point there is almost no damping force. When the load changes instantaneously, the locking control valve of the hydraulic damper is activated. At this time, it generates a counter-resistance of the same magnitude as the vibration force, preventing the pipeline from generating large vibrations or displacements, reducing the amplitude, and thus protecting the pipeline.
[0003] Hydraulic dampers are effective in reducing the adverse effects of low-frequency vibration on pipelines, thus protecting them. However, they cannot address high-frequency pipeline vibration. When pipelines encounter high-frequency vibration, cracking due to the vibration can still occur. Furthermore, the vibration can be transferred to the steel beams on which the dampers are installed, causing vibration in other connected equipment and compromising the safe operation of the pipeline. Utility Model Content
[0004] To address the technical problems of existing hydraulic dampers being unable to solve high-frequency pipeline vibration issues, and the pipeline vibration being transferred to the steel beam on which the hydraulic damper is installed, causing vibration in other connected equipment and hindering the safe operation of the pipeline, this utility model provides the following technical solution.
[0005] This utility model discloses a flexible damping device, comprising an upper connecting plate connected to a pipe clamp accessory and a lower connecting plate connected to a fixed steel beam. The lower part of the upper connecting plate is fixedly connected to a hollow mounting body with a screw plug on its outer wall. The inner cavity of the mounting body is filled with a plurality of damping particles through the screw plug. The lower part of the mounting body is fixedly connected to a flexible body, and the lower end of the flexible body is fixedly connected to the lower connecting plate.
[0006] As a further technical solution, the flexible body is made of a rubber material with a mesh structure.
[0007] As a further technical solution, the flexible body has several cavities evenly arranged in the vertical direction inside, and the cavities are filled with fillers.
[0008] As a further technical solution, the damping particles are rubber particles or metal particles.
[0009] As a further technical solution, the flexible body is fitted with a corrugated sleeve that is fixedly connected to the mounting body and the lower connecting plate.
[0010] As a further technical solution, the inner cavity of the mounting body is provided with several partitions in the longitudinal direction, and the partitions divide the inner cavity of the mounting body into multiple filling cavities, in which the damping particles are uniformly filled.
[0011] The beneficial effects of this invention are as follows: The mounting body is filled with damping particles, which transfer pipeline vibrations to the damping particles. These particles move at high speed within the mounting body, and the collisions and friction between the particles themselves, as well as between the particles and the partition, upper connecting plate, and mounting body, convert some of the vibration energy into heat energy released into the environment, reducing the adverse effects of high-frequency vibrations on the pipeline. Simultaneously, the weight and vibration of the pipeline are applied to the flexible body through the upper connecting plate and mounting body. The pipeline vibration is isolated by the flexible body, which acts as a load-bearing and vibration-isolieving element, preventing pipeline vibrations from being transmitted to the fixed steel beam and ensuring the safe operation of the pipeline.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0016] In the description of this utility model, it should be understood that the terms "upper" and "lower" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0017] like Figure 1 and Figure 2 As shown, this utility model discloses a flexible damping device, comprising an upper connecting plate 1 connected to a pipe clamp accessory and a lower connecting plate 8 connected to a fixed steel beam. After the pipe is connected to the pipe clamp accessory, the pipe clamp accessory is fixedly connected to the upper connecting plate 1, and the lower connecting plate 8 is connected to the fixed steel beam.
[0018] In a preferred embodiment, a hollow mounting body 5 is fixedly connected to the lower part of the upper connecting plate 1. The mounting body 5 is a hollow cylindrical structure. Multiple screw plugs 4 are provided on the outer wall of the mounting body 5, and several damping particles 3 are filled into the inner cavity of the mounting body 5 through the screw plugs 4. The damping particles 3 can be rubber particles or metal particles. The damping particles 3 fill the mounting body 5 completely. When the pipeline vibrates, the vibration can be transmitted to the damping particles 3 through the upper connecting plate 1 and the mounting body 5. The vibration direction of each damping particle 3 is basically opposite to the vibration direction of the pipeline. This generates a damping force that hinders the vibration of the mounting body 5 and the upper connecting plate 1. This damping force is the force that reduces the vibration of the pipeline, effectively mitigating the adverse effects of low-frequency and high-frequency vibrations on the pipeline.
[0019] In a preferred embodiment, the inner cavity of the mounting body 5 is longitudinally provided with several partitions 2, which divide the inner cavity of the mounting body 5 into multiple filling cavities, in which damping particles 3 are uniformly filled. Thus, the damping particles 3 are evenly distributed in each cavity, further ensuring that the vibration of the pipeline is evenly transmitted within each cavity, allowing the damping particles 3 to evenly distribute the vibration from the pipeline. When the damping particles 3 move at high speed within the mounting body 5, the mutual collisions and friction between the damping particles 3 and the partitions 2, the upper connecting plate 1, and the mounting body 5 can convert some of the vibration energy into heat energy released into the environment, reducing the adverse effects of high-frequency vibration on the pipeline.
[0020] In this embodiment, there are two partitions 2, which divide the inner cavity of the mounting body 5 into three accommodating cavities. Each accommodating cavity is provided with a screw plug 4 on the outside, so that the damping particles can be filled into each accommodating cavity of the mounting body 5 through the screw plug 4, so that the damping particles 3 are evenly distributed in each accommodating cavity.
[0021] In a preferred embodiment, a flexible body 7 is fixedly connected to the lower part of the mounting body 5, and the lower end of the flexible body 7 is fixedly connected to the lower connecting plate 8. The weight and vibration of the pipeline are applied to the flexible body 7 through the upper connecting plate 1 and the mounting body 5. The vibration of the pipeline is isolated by the flexible body 7. The flexible body 7 plays the role of bearing and vibration isolation, preventing the pipeline vibration from being transmitted to the fixed steel beam and ensuring the safe operation of the pipeline.
[0022] In a preferred embodiment, the flexible body 7 is made of a mesh-like rubber material, which can effectively prevent pipeline vibration from being transmitted to the fixed steel beam. Of course, the flexible body 7 can also be an independent rubber column, which can also prevent pipeline vibration from being transmitted to the fixed steel beam. Similarly, the flexible body 7 can also have other similar structures. For example, the flexible body 7 may have several cavities 9 evenly distributed in the vertical direction, and each cavity 9 may be filled with a filler 10, which can be a rubber block or a metal block. The even distribution of multiple cavities 9 and the filling of multiple fillers 10 within the cavities 9 can further improve the load-bearing capacity of the flexible body 7 for the pipeline.
[0023] To ensure the dustproof effect of the flexible body 7, a corrugated sleeve 6 is provided around the outer periphery of the flexible body 7 and is fixedly connected to the mounting body 5 and the lower connecting plate 8. The corrugated sleeve 6 is a corrugated rubber sleeve that can move with the vibration displacement of the mounting body 5 and the flexible body 7, ensuring the safe operation of the flexible body 7 in harsh environments.
[0024] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
