Description

Technical Field

[0001] This utility model relates to the field of vibration reduction and protection technology, specifically a multi-level vibration reduction platform. Background Technology

[0002] Currently, in applications such as precision equipment installation, experimental instrument testing, and industrial equipment operation, the foundation platform on which the equipment rests is often affected by environmental vibrations, leading to reduced measurement accuracy or decreased equipment operational stability. Common vibration damping platforms often employ single-stage rubber pads or single-stage spring structures, which can weaken vertical vibration transmission to some extent, but they still struggle to effectively absorb and isolate multi-directional, multi-frequency vibration signals. Furthermore, traditional vibration damping structures generally suffer from poor sound absorption, low structural stiffness, and unreasonable constraint mechanisms. When subjected to external impacts or changes in the equipment's center of gravity, the platform is prone to displacement or tilting, resulting in unstable overall vibration damping performance.

[0003] On the other hand, although some vibration damping platforms incorporate damping materials or sound insulation layers into their structural layers, the overall structure is a single-layered combination, failing to form a multi-level energy attenuation system. This results in insufficient vibration damping and sound absorption performance, making it difficult to simultaneously address the combined vertical and lateral vibration suppression requirements. Therefore, there is an urgent need for a multi-level vibration damping platform with a stable structure, significant graded vibration absorption effect, and good limit protection and noise control performance to improve the operational stability and testing accuracy of equipment in vibration environments. Therefore, a multi-level vibration damping platform is proposed to address the above issues. Utility Model Content

Rubber vibration dampers are evenly installed on the outer side of the top surface of the platform plate structure. Vibration damping support structures are evenly installed on the outer side of the bottom surface of the platform plate structure.

[0011] Preferably, the upper and lower limiters include an angle iron, a support rod is installed on the lower side of the angle iron, a support ring is installed at the bottom end of the support rod, and a second fixing bolt is installed on the inner side of the support ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, multi-dimensional buffering and limiting protection against equipment vibration is achieved by evenly distributing rubber vibration dampers at the top of the platform structure, arranging a multi-level vibration damping support structure at the bottom, and setting left and right limiter structures on the outside of the supports and upper and lower limiters on the sides of the platform. The platform structure adopts a multi-layer composite structure consisting of an outer steel plate, a damping layer, high-density sound insulation cotton, a vibration damping layer, and sound-absorbing particles stacked sequentially, forming a graded energy absorption system that can simultaneously weaken structurally transmitted vibrations and airborne noise. The vibration damping support structure, through the combination of multi-level springs and multi-layer vibration damping pads, significantly improves the vibration damping efficiency in the low-frequency to mid-high frequency range and reduces the platform resonance amplitude. The addition of the limiter structure effectively prevents the platform from lateral or vertical displacement when subjected to impact or off-center loading, ensuring the stability and safety of equipment operation.

Unless otherwise stated, these directional terms 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 on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0017] Please see Figure 1-7 This utility model provides a technical solution: A multi-stage vibration damping platform includes a platform plate structure 1. Several rubber vibration dampers 2 are evenly installed on the outer side of the top surface of the platform plate structure 1 to provide primary buffering of vibrations from the upper equipment. Vibration damping support structures 3 are evenly installed on the outer side of the bottom surface of the platform plate structure 1. These support structures 3 serve as the main load-bearing and graded vibration damping units, absorbing and dispersing the overall vibration of the platform in multiple stages. Left and right limiter structures 4 are installed on the outer side of the vibration damping support structures 3 to prevent horizontal displacement of the platform when subjected to lateral impacts or load shifts. Upper and lower limiters 5 are installed in the middle of the left and right sides of the platform plate structure 1 to limit the vertical displacement of the platform, preventing the platform from lifting or sinking due to elastic rebound or resonance.

[0018] The platform structure 1 includes an outer steel plate 11, which forms the load-bearing outer shell of the platform and has high strength and impact resistance. A damping layer 12, high-density sound insulation cotton 13, a vibration damping layer 14, and sound-absorbing particles 15 are sequentially installed on the inner side of the outer steel plate 11. The damping layer 12 is made of high-polymer composite rubber material and is mainly used to weaken the transmission of high-frequency vibrations between structural layers. The high-density sound insulation cotton 13 is made of polyester fiber or glass fiber material, which can effectively isolate sound wave propagation and improve the sound absorption performance of the entire platform. The vibration damping layer 14 is made of high-resilience foam rubber and is used to absorb mid-to-low frequency mechanical vibration energy. The sound-absorbing particles 15 fill the internal cavity of the platform structure 1 and can further consume vibration energy through friction and compression between particles, achieving a multi-stage energy dissipation effect. The outer steel plate 11, damping layer 12, high-density sound insulation cotton 13, and vibration damping layer 14 are all made into a box structure, and each box has a removable cover on its upper side for easy maintenance, replacement, or adjustment of the internal structure.

[0019] The vibration damping support structure 3 includes a spring vibration damper 31, which supports the platform body and provides elastic vibration damping. The bottom end of the spring vibration damper 31 is fixedly connected to a base plate 32. A first fixed steel plate 33 and a first vibration damping pad 34 are sequentially installed on the bottom side of the base plate 32. The first vibration damping pad 34 is made of natural rubber and can absorb the contact impact between the platform and the ground. To further enhance vibration isolation performance, the bottom end of the first vibration damping pad 34 is also connected to a second fixed steel plate 35 and a second vibration damping pad 36. The second vibration damping pad 36 is also made of a rubber-silicone composite structure, which can effectively disperse residual vibration energy. A third fixed steel plate 37 is fixed to the bottom end of the second vibration damping pad 36, and a third vibration damping pad 38 is installed on the lower side of the third fixed steel plate 37, thus forming a three-layer vibration damping pad and multi-level steel plate combination structure, achieving gradual weakening and isolation of vibrations in different frequency bands.

[0020] The left and right limiter structure 4 includes a horizontal plate 41, which is installed in the bottom area on both sides of the vibration damping support structure 3. Vertical plates 42, perpendicularly arranged to each other, are installed on the upper side of the horizontal plate 41. The sides of the vertical plates 42 are in contact with the outer surface of the bottom end of the vibration damping support structure 3, limiting the lateral displacement of the support through surface contact. First fixing bolts 43 are installed on both sides of the horizontal plate 41, which can firmly lock the limiter structure onto the base plate 32, further improving the overall impact resistance and lateral restraint strength.

[0021] The upper and lower limiters 5 include an angle iron 51, with a support rod 52 welded to the lower side of the angle iron 51. A support ring 53 is installed at the bottom end of the support rod 52. A second fixing bolt 54 is installed on the inner side of the support ring 53 for adjusting the support height or locking the limit position. When the platform is subjected to external vibration, the support rod 52 can limit the vertical displacement, preventing the platform from excessively rising due to elastic recovery, and at the same time preventing the platform from excessively compressing and descending due to external forces, thereby ensuring that the platform remains stable under vibration.

[0022] During use, the equipment requiring vibration isolation is placed on top of the platform structure 1. The rubber vibration damper 2 first absorbs the primary vibration generated by the equipment. The vibration damping support structure 3 below it uses spring vibration dampers 31 and multiple layers of vibration damping pads to attenuate low and medium frequency vibrations in two and three stages. The damping layer 12, sound insulation cotton 13, vibration damping layer 14, and sound-absorbing particles 15 inside the platform structure 1 work together to absorb and diffuse residual vibration and noise, achieving dual control of structural vibration and noise. The limiter structure 4 and the upper and lower limiters 5 together provide multi-directional stability constraints, enabling the platform to maintain balance and safety under high loads or impacts.
