[0028] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure more clear, the embodiments of the present disclosure are further described in detail below in combination with the embodiments and drawings. The schematic implementation methods of the embodiments of the present disclosure and their descriptions are only used to explain the embodiments of the present disclosure and are not intended to limit the embodiments of the present disclosure.

[0029] like Figure 1 As shown, the shock-proof foundation support device of the present application includes a shock-proof base 1, a multi-stage telescopic rod 2, an elastic damper 3, a friction shock-absorbing assembly 4, and a mass block 5. These components, through a reasonable layout and connection method, constitute a multi-degree-of-freedom vibration system that can effectively reduce the impact of ground vibration on the superstructure and improve the overall stability of the system.

[0030] The shock-isolating base 1 serves as the foundation of the entire device. Its primary function is to be fixed to the foundation surface and provide stable support. It is typically constructed from high-quality materials, such as high-strength steel or specialty alloys, to ensure it can withstand various external stresses and prolonged use. The base is designed with multiple mounting holes and fasteners to securely fasten the device to the foundation. Furthermore, a rubber pad or similar material can be placed underneath the shock-isolating base 1 to further enhance its shockproofing and durability.

[0031] The multi-stage telescopic rod 2 is a key component mounted on the shock-absorbing base 1. It automatically adjusts its length to compensate for ground vibrations, thereby maintaining the stability of the device's superstructure. The rod 2 consists of multiple retractable tubular sections connected by a sophisticated mechanical structure. The interior and exterior of each section are specially treated to ensure smooth expansion and contraction without binding. A travel sensor and control system can also be installed within the rod 2 to monitor vibrations in real time and adjust its length for more precise displacement compensation.

[0032] The elastic damper 3 is a key vibration attenuation component. It is installed between or outside the multi-stage telescopic rods 2 and dissipates vibration energy through deformation when vibration occurs. The elastic damper 3 is usually composed of springs and other flexible materials and can exhibit good damping performance in different frequency ranges. In addition, a layer of viscous fluid is provided inside the elastic damper 3 to further dissipate vibration energy through flow. This composite design not only improves the damping effect of the elastic damper 3, but also extends its service life. The installation position and number of the elastic damper 3 are optimized according to the specific project requirements to achieve the best shock absorption effect.

[0033] The friction damping assembly 4 is another important damping mechanism. Positioned within or parallel to the multi-stage telescopic rod 2, it reduces vibration amplitude through the friction generated by their interaction. The friction damping assembly 4 is composed of multiple sets of sliding components and friction pads. The contact surfaces between the sliding components are constructed from high-strength, wear-resistant materials, such as tungsten carbide or Teflon, to reduce wear and ensure a long service life. By rationally designing the magnitude and distribution of friction, the impact of high-frequency vibrations on the system can be effectively reduced, further improving the overall stability of the device. The friction damping assembly 4 can also work in conjunction with other damping components to form a multi-stage damping system, enhancing the overall damping effect.

[0034] The mass block 5 is located at the top of the multi-stage telescopic rod 2 and has a sufficiently large mass and inertia, which helps to improve the overall stability of the system and dissipate more vibration energy in the resonant state. The shape and material selection of the mass block 5 need to take into account its mass, strength and stability. It is usually made of high-density metal or composite materials. In order to ensure the reliability and durability of the mass block 5, its surface has been finely processed and the internal structure has also been reinforced. The mass block 5 can be firmly connected to the top of the multi-stage telescopic rod 2 by bolts, welding or other means. The presence of the mass block 5 not only increases the natural frequency of the system, making it less likely to enter a resonant state, but also consumes a large amount of energy in a high-frequency vibration environment through its own inertia, thereby further reducing the impact on the superstructure.

[0035] These components work together to form a multi-degree-of-freedom vibration system. This system leverages the unique characteristics and interactions of each component to significantly improve energy absorption efficiency and effectively stabilize the superstructure. In specific engineering applications, the specific parameters of each component, such as the length of the telescopic rod and the stiffness and friction of the elastic damper 3, can be adjusted to suit different seismic frequency ranges and building requirements to achieve optimal vibration reduction and economic benefits.

[0036] In one embodiment, the shock-proof foundation support device of the present application is further configured with an adjustable bolt 6 on the shock-proof base 1. This design significantly improves the ability to adjust the contact and compression state between the device and the foundation. By adjusting the adjustable bolt 6, the installation state of the entire device can be precisely controlled, thereby ensuring that the device can be firmly installed under various ground conditions. Especially under high-frequency vibration conditions, this adjustment capability not only enhances the fixing strength of the device, but also improves the overall stability and shock resistance, thereby enabling the device to more effectively absorb and disperse external vibration energy.

[0037] Specifically, the upper and lower portions of the shock-isolating base 1 are designed with corresponding threaded holes for mounting an adjustable bolt 6. The lower end of the adjustable bolt 6 screws into the threaded hole below the base, while the upper end protrudes above the shock-isolating base 1. During installation, by rotating the adjustable bolt 6, varying the pressure between the base and the foundation can be achieved, thereby fine-tuning the contact between the device and the foundation. Furthermore, the design of the adjustable bolt 6 allows the operator to make real-time adjustments based on the specific usage environment and equipment requirements to ensure optimal installation.

[0038] For example, in a specific application scenario, if the device detects significant vibration in a certain direction, the operator can increase the contact pressure in that direction by rotating the corresponding adjustable bolt 6, thereby improving the stability of the device and reducing unnecessary vibration. In this way, the device can maintain high operating efficiency and reliability under various complex working conditions.

[0039] In one embodiment, Figure 3 As shown, the multi-stage telescopic rod 2 of the shockproof foundation support device of the present application is equipped with a spring drive mechanism 7. This mechanism can more promptly and accurately adjust the position changes of the multi-stage telescopic rod 2 when vibration occurs, thereby effectively addressing the impact of high-frequency vibration and ensuring maximum energy absorption efficiency. The addition of the spring drive mechanism 7 enables the device to maintain good adaptability and stability in the face of vibrations of various frequencies and intensities. This design not only improves the overall seismic resistance of the device, but also reduces the risk of secondary injuries caused by vibration.

[0040] Specifically, the multi-stage telescopic rod 2 is composed of multiple interlocking rods, with gaps between each stage to accommodate the internal spring drive mechanism 7. The spring drive mechanism 7 primarily comprises a highly elastic spring assembly and other necessary transmission components. When vibration occurs, external vibration energy is transferred to the multi-stage telescopic rod 2. The spring drive mechanism 7 absorbs and dissipates this energy through compression or expansion, thereby achieving a shock-absorbing effect. Furthermore, the design of the spring drive mechanism 7 can be adjusted to suit different application scenarios, adapting to varying load conditions and vibration frequencies.

[0041] For example, in one embodiment, the spring drive mechanism 7 is mounted within the multi-stage telescopic rod 2 via a precise system of guide rails and sliders. This system ensures the free movement of the spring drive mechanism 7 within the multi-stage telescopic rod 2, while ensuring smooth and accurate movement. When the external environment changes, the spring drive mechanism 7 can quickly respond and adjust the position of the multi-stage telescopic rod 2, achieving rapid vibration attenuation. In this way, the multi-stage telescopic rod 2 can effectively absorb and dissipate energy, ensuring the stability and reliability of the entire base support device.

[0042] In one embodiment, the elastic damper 3 of the shockproof foundation support device of the present application is filled with a liquid material 8 with high viscosity, thereby exhibiting better energy conversion and dissipation characteristics in a high-frequency vibration environment. By filling the damper with a liquid with a high molecular weight and high viscosity, this design effectively improves the stability and damping performance of the system under high-frequency vibration conditions. This technical means can not only significantly reduce the damage to the equipment caused by vibration, but also improve the durability and reliability of the device. In addition, the use of viscous liquid enables the device to maintain a high damping effect under various complex working conditions, thereby extending the service life of the device and reducing maintenance costs.

[0043] In the specific technical implementation process, the design of the elastic damper 3 generally includes two parts: an outer shell and an inner core. The outer shell is usually made of a high-strength material, such as steel or aluminum alloy, to ensure its structural stability and durability. The inner core is composed of multiple layered or spiral elastic elements, and the spaces between these elastic elements are filled with a highly viscous liquid material 8. Specifically, during assembly, a viscous liquid can be injected into the chamber between the outer shell and the inner core, and a sealing structure is used to ensure that the liquid does not leak out. For example, a rubber sealing ring or a special sealant can be used to keep the damper sealed during operation, thereby fully utilizing the damping effect of the viscous liquid.

[0044] In one embodiment, the shockproof foundation support device of the present application further optimizes its shock absorption performance. The key to this device lies in the improvement of the friction shock absorption component 4. The friction shock absorption component 4 can significantly improve the surface contact resistance of the device during relative displacement by adding a porous structural material 9. This porous structural material 9 has a high specific surface area and complex internal pores, which can form more contact points during relative motion, thereby increasing friction and effectively improving the shock absorption effect. More importantly, this material can still maintain stable performance during high-speed movement, ensuring that the device can play the best shock absorption role under various working conditions. This not only improves the stability of the overall structure, but also extends the service life of the device, making the device suitable for more complex and harsh working environments.

[0045] Specifically, the porous structural material 9 can be made of a material with high elasticity and wear resistance, such as polyurethane foam or metal foam. These materials are embedded in the contact surface of the friction damping component 4 and fit tightly with the base part and the upper support structure of the device. By precisely controlling the pore size and porosity of the material, it is possible to ensure sufficient contact resistance without adding additional mass and volume. In addition, the installation method of the porous structural material 9 is also very flexible. It can be fixed by bonding or embedding to ensure that it is not easy to fall off or deform during long-term use. This design not only improves the reliability and stability of the device, but also simplifies the maintenance and replacement process.

[0046] In one embodiment, the shockproof foundation support device of the present application has the ability to significantly enhance its resistance to external high-amplitude vibrations by adding an additional inertial weight module 10. The mass block 5 of the device achieves a significant increase in inertial force without increasing the total volume by adding an additional inertial weight module 10. This design effectively enhances the stability of the device in a high-amplitude vibration environment, allowing the structure to maintain a better steady-state response under extreme conditions. The additional inertial weight module 10 is usually made of high-strength material to ensure that its weight density and mechanical strength meet the actual application requirements. The shape and size of the module can be flexibly designed according to different application scenarios and structural requirements.

[0047] Specifically, the mass block 5 and the additional inertial weight module 10 can be connected securely by bolts, nuts, or other mechanical fasteners to ensure that the module does not shift or fall off during high-amplitude vibrations. In addition, the additional inertial weight module 10 can be designed as a modular unit, and users can choose different numbers of modules for installation based on the specific usage scenario and the required additional weight. For example, multiple connection points can be reserved inside the mass block 5, and each connection point can be installed with one or more additional inertial weight modules 10, thereby achieving different degrees of inertial force enhancement. This modular design not only improves the flexibility of the device, but also simplifies subsequent installation and maintenance work.

[0048] In one embodiment, Figure 3 As shown, the shock-resistant foundation support device of the present application features a unique self-locking buckle structure 11 to enhance its stability and reliability in high-frequency vibration environments. A core feature of this device is the self-locking buckle structure 11 at the connection between the shock-resistant base 1 and the multi-stage telescopic rod 2. This structural design ensures that even after a small amount of displacement, a new locking point is quickly formed, effectively preventing component loosening caused by sustained high-frequency vibration. This design not only improves the overall stability of the device but also significantly extends its service life and maintenance cycle.

[0049] The shockproof base 1 is the foundation of the entire device, responsible for providing stable support and absorbing vibration energy in the external environment. The multi-stage telescopic rod 2 is the height adjustment part of the device, which realizes flexible adjustment of height through a multi-stage structure. The self-locking buckle structure 11 is located at the connection between the two. Through precise mechanical coordination, it can quickly form a new locking state after a slight displacement. Specifically, the buckle structure is composed of a plurality of closely connected locking units, which interact with each other through inclined surfaces or convex and concave structures. When a slight displacement occurs, the locking unit will automatically clamp and form a new locking point. This design ensures that the entire device can maintain a high degree of stability and reliability whether it is in a stationary state or when subjected to vibration shock.

[0050] For example, to achieve the aforementioned features, a spring-and-inclined mechanism can be employed at the connection between the shock-absorbing base 1 and the multi-stage telescopic rod 2. When the multi-stage telescopic rod 2 undergoes slight displacement, the inclined surface forces the spring to push the locking element into position, instantly creating a new locking point and effectively preventing loosening caused by frequent vibration. Furthermore, this design provides additional locking security without compromising the flexible adjustment of the multi-stage telescopic rod 2.

[0051] In one embodiment, the shockproof foundation support device of the present application provides an improved elastic damper 3, which is intended to improve its working efficiency under various working conditions. Specifically, the elastic damper 3 particularly adopts a damping core 12 made of a composite rubber material, which has the characteristics of high internal resistance. By adopting a composite rubber material with high internal resistance, the damping core can provide a more effective vibration reduction effect in different vibration environments, thereby improving the stability and durability of the entire support device. In addition, the material can also flexibly adjust its hardness ratio according to the different needs of actual application scenarios, further enhancing the adaptability and reliability of the device.

[0052] The specific properties of the composite rubber material enable the damping core to effectively absorb and disperse energy when subjected to external shock and vibration, reducing the risk of vibration transmission to the supported equipment. By adjusting the composite rubber material ratio, the damping core's hardness and damping characteristics can be optimized to meet the requirements of different working conditions. This design not only improves the overall performance of the seismic foundation support device but also extends its service life.

[0053] In one embodiment, Figure 4 As shown, the damping core is installed inside the elastic damper 3. This combination ensures that the damping core can be evenly stressed when subjected to external forces, thereby maximizing its vibration reduction effect. At the same time, the damping core made of composite rubber is seamlessly connected to other components of the elastic damper 3 (such as metal springs) through precise processing technology, ensuring the stability of the entire device in high-vibration environments. For example, the composite rubber material can be fixed to metal parts through a vulcanization process to ensure its long-term stable operation.

[0054] In one embodiment, returning reference Figure 1 and Figure 2 To address the problem of excessive rigidity in existing structures, the shockproof foundation support device of this application incorporates an auxiliary airbag 15 on the side of the multi-stage telescopic rod 2. This design allows the auxiliary airbag 15 to rapidly inflate in the event of strong vibrations, thereby forming a temporary buffer zone and effectively reducing the reverse impact caused by hard contact. Specifically, the connection between the multi-stage telescopic rod 2 and the auxiliary airbag 15 is achieved through flexible materials or pipes, ensuring that the airbag can respond quickly in the event of vibrations. The auxiliary airbag 15 is made of a high-strength and elastic material, capable of maintaining structural integrity and functional effectiveness under extreme conditions.

[0055] For example, in terms of technical implementation, the auxiliary airbag 15 can be mounted on the side of the multi-stage telescopic rod 2 and connected to an automatic inflation system via a dedicated air tube. This inflation system, based on signals from a vibration sensor, rapidly triggers inflation when strong vibrations are detected. In this way, the auxiliary airbag 15 can expand from a flattened state to a preset volume in a very short time, effectively dispersing and absorbing external vibration energy and reducing the overall stress on the device. This design not only enhances the device's seismic resistance but also extends its service life.

[0056] In actual operation, when the device is in use, the anti-vibration base 1 is first firmly fixed to the foundation surface, providing a solid foundation for the entire system. Once the ground vibrates, the multi-stage telescopic rod 2 automatically adjusts its length based on the specific amplitude of the ground vibration. This telescopic movement effectively offsets the irregular displacement caused by the ground and maintains the top of the device at its preset height. Simultaneously, the elastic damper 3 activates its function, transforming and absorbing the kinetic energy generated by the multi-stage telescopic rod 2 through material deformation. This energy is converted into heat and dissipated into the environment, significantly reducing the impact of vibration on the system. Furthermore, the friction damping assembly 4 is also activated. It is either located inside the telescopic rod or parallel to it. Its primary function is to further reduce the vibration amplitude by utilizing the mutual friction generated by the movement of the various components, thereby enhancing the safety and durability of the entire structure. The most striking feature of the design is the top mass 5, which has considerable mass. Its design objective is to enhance the dynamic stability of the system through its large inertia. When large ground motion occurs, it dissipates the accumulated vibration energy through resonance. Through the precise design and coordination of the shock-isolating base 1, multi-stage telescopic rod 2, elastic damper 3, friction shock-absorbing assembly 4, and mass block 5, the shock-isolating foundation support device can maintain efficient working performance under vibration conditions within the high and low frequency ranges, ensuring the safety and stability of the structure supported above.
