Description

Technical Field

[0001] This utility model relates to the field of vibration reduction in high-precision production equipment, and in particular to a vibration reduction base. Background Technology

[0002] For high-precision production equipment such as lithography production lines, semiconductor manufacturing, optical inspection, and scientific research experiments, the vibration requirements of the working environment are extremely high. Even the slightest vibration can lead to increased measurement errors, deviations in experimental results, and even affect the normal operation and service life of the instruments. Furthermore, with the continuous development of high-precision instruments and equipment and the increasing complexity of application scenarios, the requirements for the accuracy, stability, and adaptability of vibration damping bases are also constantly increasing. Therefore, when arranging high-precision equipment, it is necessary to set up a foundation support that can effectively isolate complex vibration interference.

[0003] In the prior art, CN220851287U discloses an integrally assembled anti-micro-vibration base. This base achieves anti-micro-vibration through a concrete panel, steel column, and diagonal bracing structure. This type of anti-vibration base mainly resists vibration through a rigid structure. When the vibration frequency is close to the resonant frequency of the steel structure or concrete, it cannot maintain its anti-vibration performance.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] To address the problem that existing vibration-damping bases primarily resist vibration through rigid structures, which still produce vibration when the vibration frequency approaches the resonant frequency of the base material, making it difficult to meet vibration resistance requirements under different conditions, this utility model proposes a vibration-damping base.

[0006] This utility model is achieved through the following technical solution:

[0007] A vibration damping base, wherein the vibration damping base comprises:

[0008] The platform includes a frame and a concrete layer poured into the frame.

[0009] The leg column is provided in a plurality of them. The plurality of leg columns are arranged circumferentially along the edge of the platform and one end is connected to the platform. A support assembly is provided between adjacent leg columns. The interior of the leg column is filled with damping and vibration-damping quartz sand.

[0010] Vibration damping pads are installed at the connection point between the leg column and the platform.

[0011] The vibration damping base includes a frame with several layers of steel mesh inside, the layers of steel mesh being arranged at predetermined intervals, and a concrete layer enclosing the layers of steel mesh.

[0012] The vibration damping base includes a dustproof layer on the platform, which is a three-layer epoxy resin layer and is applied to the precision-polished concrete layer.

[0013] The vibration damping base, wherein the support assembly includes:

[0014] A number of horizontal cross braces are arranged at predetermined intervals along the vertical direction, and the two ends of each horizontal cross brace are fixedly connected to the adjacent leg column.

[0015] The supporting diagonal braces are arranged at a predetermined angle between two adjacent horizontal braces, and the two ends of the supporting diagonal braces are respectively fixedly connected to the leg column.

[0016] The vibration damping base, wherein the support assembly further includes:

[0017] The mounting panel is fixedly installed at the end of the horizontal cross brace and the supporting diagonal brace, and the mounting panel is fixedly connected to the leg column by bolts.

[0018] The vibration damping base wherein the ends of the horizontal cross brace and the supporting diagonal brace, which are located at the same position, are fixedly connected to the same mounting panel.

[0019] The vibration damping base, wherein the number of the supporting diagonal braces between adjacent horizontal cross braces is one or two;

[0020] When there are two diagonal braces between adjacent horizontal braces, the two diagonal braces are arranged crosswise, and the crosswise part of the two diagonal braces is fixedly connected by a clamp.

[0021] The vibration damping base includes a base plate fixedly installed at the other end of the leg column. The length and width of the base plate are greater than the length and width of the cross-section of the leg column. The base plate includes two panels with a damping pad sandwiched between them. The base plate is connected to the ground.

[0022] The vibration damping base has a mortar layer on the side of the base plate away from the leg column. The mortar layer is epoxy mortar and is used to level the contact surface between the base plate and the ground.

[0023] The vibration damping base has a plurality of elbow plates spaced apart on the outer side of the base plate corresponding to the leg column. The elbow plates are perpendicular to the base plate, and one side of the elbow plate is fixedly connected to the base plate and the other side is fixedly connected to the leg column.

[0024] The beneficial effects of this utility model are as follows: This utility model installs production equipment on a platform with a frame and a poured concrete layer, and supports the platform with legs filled with damping and vibration-damping quartz sand. The legs and the platform are connected by vibration-damping pads. When the equipment vibrates, the damping and vibration-damping quartz sand in the legs absorbs the vibration energy through mutual friction and collision, and the vibration amplitude is reduced by the vibration-damping pads to prevent resonance. This can effectively reduce the vibration generated by the equipment operation and the impact of environmental vibration on the equipment, providing a vibration-resistant foundation for the operation of high-precision equipment.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0032] In the prior art, CN220851287U discloses an integrally assembled anti-micro-vibration base. This base achieves anti-micro-vibration through a concrete panel, steel column, and diagonal bracing structure. This type of anti-vibration base mainly resists vibration through a rigid structure. When the vibration frequency is close to the resonant frequency of the steel structure or concrete, it cannot maintain its anti-vibration performance.

[0033] In view of the above-mentioned problems in the prior art, the present invention provides a vibration damping base, such as... Figure 1 , Figure 2 and Figure 3 As shown, the vibration damping base includes: a platform 100, which includes a frame 110 and a concrete layer 120 poured inside the frame 110; leg columns 200, of which several leg columns 200 are arranged at intervals around the edge of the platform 100 and one end is connected to the platform 100; a support assembly 300 is provided between adjacent leg columns 200; and damping and vibration-damping quartz sand 210 is filled inside the leg columns 200; and vibration damping pads 400 are provided at the connection between the leg columns 200 and the platform 100.

[0034] This invention utilizes a platform 100 with a frame 110 and a poured concrete layer 120 to mount production equipment. The platform 100 is supported by legs 200 filled with damping and vibration-damping quartz sand 210. The legs 200 and the platform 100 are connected by vibration-damping pads 400. When the equipment vibrates, the damping and vibration-damping quartz sand 210 in the legs 200 absorbs vibration energy through mutual friction and collision, and the vibration-damping pads 400 reduce the vibration amplitude, preventing resonance. This effectively reduces the impact of vibration generated during equipment operation and environmental vibration on the equipment, providing a vibration-resistant foundation for the operation of high-precision equipment.

[0035] In the above embodiments, such as Figure 1 , Figure 2 and Figure 3As shown, the main body of the vibration damping base of this utility model consists of a platform 100, legs 200, and vibration damping pads 400. The platform 100 is used to support and install high-precision production equipment. In this embodiment, the platform 100 is specifically composed of a frame 110 and a concrete layer 120 poured inside the frame 110. The frame 110 is made of thickened medium carbon steel plate, forming a frame structure with an internal cavity. During installation, the concrete layer 120 is poured inside the frame 110. The concrete uses high-rigidity C45 cement, thereby achieving stable support for the high-precision production equipment.

[0036] Several leg columns 200 are provided. Each leg column 200 is a steel structure column with an internal cavity to support the platform 100. During actual installation, the leg columns 200 are arranged circumferentially around the edge of the platform 100, ensuring that the upper surface of the platform 100 is horizontal. While the leg columns 200 are connected to the platform 100, support components 300 are also provided between adjacent leg columns 200 to limit their relative positions and prevent the platform 100 from tilting due to deformation of the installation area. The cavities of the leg columns 200 are filled with damping and vibration-damping quartz sand 210. The working principle of the damping quartz sand is mainly based on the friction, collision, and energy dissipation between particles. It absorbs and consumes vibration energy to achieve a vibration reduction effect. The specific principle of its vibration reduction is as follows:

[0037] Firstly, it dissipates energy through particle friction: Quartz sand is composed of a large number of hard, fine particles. When subjected to vibration or impact, these particles slide, roll, and collide relative to each other. The frictional force on the particle surface and the mechanical energy generated by the collision are converted into heat energy and dissipated, thus consuming vibration energy and weakening vibration transmission. Secondly, it hinders vibration propagation: The filled quartz sand can change the stiffness and damping characteristics of the vibration system. When vibration waves pass through the quartz sand particle layer, they are dispersed, reflected, and attenuated due to the interaction between the particles, reducing the efficiency of vibration transmission to the external structure. Thirdly, it can buffer impact loads: When subjected to instantaneous impact, quartz sand particles absorb impact energy through deformation methods such as compression and misalignment, prolonging the impact time and mitigating the direct impact on equipment or structures.

[0038] The vibration damping pad 400 is used to form an elastic connection between the platform 100 and the leg column 200. The vibration damping pad 400 can be made of elastic materials such as rubber. It utilizes the viscoelastic properties of rubber materials to achieve vibration damping and buffering. Its working principle is mainly based on the following aspects: First, viscoelastic energy dissipation: Rubber is a viscoelastic material, possessing both elasticity (able to store deformation energy generated under external force) and viscosity (able to dissipate energy through intermolecular friction). When external vibration or impact is transmitted to the rubber pad, the rubber deforms, and the internal molecular chains rub and entangle with each other, converting mechanical energy into heat energy and dissipating it, thereby weakening the transmission of vibration. Second, changing the vibration frequency: The damping rubber pad can change the natural vibration frequency of the system, allowing the system to avoid the resonant frequency range and preventing resonance amplification of vibration, thus playing a vibration isolation role. Third, buffering impact loads: When subjected to instantaneous impact, the rubber pad absorbs impact energy through its own elastic deformation, prolonging the impact time and reducing the impact acceleration, thereby mitigating the damage to the equipment or structure.

[0039] In actual installation, the platform 100 and the leg column 200 are connected by bolts. The vibration damping pad 400 is clamped and set at the position between the end of the leg column 200 and the platform 100 to form an elastic connection. At the same time, the bolts pass through the vibration damping pad 400 to limit the position of the vibration damping pad 400 and prevent the vibration damping pad from shifting and falling off due to long-term resistance to vibration.

[0040] In one embodiment of this utility model, when the concrete layer 120 is poured into the frame 110, several layers of reinforcing mesh (not shown in the figure, but those skilled in the art can set it according to the following description) are also laid inside the frame 110. Specifically, the reinforcing mesh is HRB400 type. These layers of reinforcing mesh are arranged vertically at predetermined intervals inside the frame 110. During the pouring of the concrete layer 120, the concrete layer 120 wraps around the layers of reinforcing mesh, and the reinforcing mesh is tightly bonded to the concrete layer 120, forming a reinforced concrete structure. This structure not only improves the overall strength and rigidity of the platform 100, but also effectively resists vibration and impact forces generated by equipment operation, ensuring the stability of the platform 100 during the operation of high-precision production equipment. Simultaneously, the reinforcing mesh also prevents cracks in the concrete layer 120 due to vibration, extending the service life of the platform 100. In practical applications, the number and spacing of the reinforcing mesh layers can be adjusted according to the equipment weight and vibration intensity to meet vibration reduction requirements in different scenarios.

[0041] Furthermore, after the concrete layer 120 inside the frame 110 is poured, the frame 110 and the concrete layer 120 form a fixed whole. Since high-precision production equipment needs to be installed on the upper surface of the platform 100, and corrosion or damage to the upper surface of the platform 100 may occur due to changes in the external environment or unexpected situations during actual use, a dustproof layer 130 is also provided on the platform 100 in this embodiment. The dustproof layer 130 is specifically provided on the concrete layer 120 after precision grinding.

[0042] The dustproof layer 130 is specifically made using a three-layer fiberglass cloth and five-layer epoxy resin coating process. "Three-layer fiberglass cloth and five-layer epoxy resin coating" is an anti-corrosion construction technique, referring to laying three layers of fiberglass cloth and applying five layers of epoxy resin coating during construction. This process creates an anti-corrosion layer with high strength, high toughness, good adhesion, and excellent corrosion resistance. Furthermore, it features strong adhesion (strong bonding to concrete); resistance to chemical corrosion (resistant to acids, alkalis, salts, chemical solvents, oils, etc.); excellent physical properties (high hardness after curing, good impact resistance, washability, and a certain degree of elasticity); and convenient construction (relatively simple construction process, can be done by brushing, coating is formed in one step, no curing period required). Combined with epoxy resin, it achieves even better protective effects.

[0043] In another possible embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the aforementioned support assembly 300 specifically consists of horizontal cross braces 310 and diagonal support braces 320. The horizontal cross braces 310 are arranged at predetermined intervals along the vertical direction between adjacent leg columns 200. Their main function is to provide horizontal support between adjacent leg columns 200, ensuring the horizontal stability of the leg columns 200 and thus guaranteeing the stability of the platform 100. The even distribution of several horizontal cross braces 310 effectively disperses the load transmitted from the platform 100, avoiding localized stress concentration.

[0044] The diagonal support 320 is inclined at a predetermined angle between two adjacent horizontal supports 310, and its two ends are fixedly connected to the leg columns 200. The diagonal support 320 and the horizontal supports 310 cooperate with each other to form a stable triangular support structure. This structure can significantly enhance the connection strength between the leg columns 200 and improve the lateral displacement resistance of the entire vibration damping base. When the platform 100 is subjected to a horizontal external force, the diagonal support 320 can convert part of the horizontal force into an axial force along the direction of the diagonal support, which is transmitted to the ground through the leg columns 200, thereby effectively reducing the horizontal displacement of the platform 100.

[0045] In actual installation, both the horizontal brace 310 and the diagonal brace 320 are made of high-strength steel to ensure that they have sufficient load-bearing capacity.

[0046] In another possible embodiment of this utility model, such as Figure 2 and Figure 3 As shown, to facilitate the installation of the support assembly 300, the support assembly 300 also includes a mounting panel 330. The mounting panel 330 is fixedly installed at the ends of the horizontal cross brace 310 and the diagonal support brace 320. The mounting panel 330 is fixedly connected to the leg column 200 by bolts. This structural arrangement allows multiple leg columns 200 and the support assembly 300 to be disassembled and assembled, reducing the transportation difficulty during the transportation process from the production site to the installation site. During transportation, the leg columns 200 and the support assembly 300 can be disassembled, packaged and transported separately, and then reassembled at the installation site. This disassembled and assembled design not only facilitates transportation but also facilitates later maintenance and replacement. When a leg column 200 or support assembly 300 is damaged, only the corresponding part needs to be replaced, without replacing the entire vibration damping base, greatly reducing maintenance costs and time. At the same time, the installation panel 330 also improves the connection accuracy and stability between the support assembly 300 and the leg column 200, ensuring the reliability and safety of the entire vibration damping base during use.

[0047] During actual installation, the ends of the horizontal cross brace 310 and the supporting diagonal brace 320 corresponding to the position are fixedly connected to the same mounting panel 330. This design allows the force of the horizontal cross brace 310 and the supporting diagonal brace 320 to be uniformly transmitted to the mounting panel 330, and then distributed to the leg column 200 through the mounting panel 330. This avoids structural deformation caused by uneven force distribution and enhances the unity of the horizontal cross brace 310 and the supporting diagonal brace 320 in dealing with the force.

[0048] In one possible embodiment of this utility model, during actual installation, the number of supporting diagonal braces 320 between adjacent horizontal cross braces 310 can be set to one or two, i.e., as shown below. Figure 2 and Figure 3 As shown in the different installation states, when there are two diagonal braces 320 between adjacent horizontal cross braces 310, the two diagonal braces 320 are arranged crosswise, and the intersection of the two diagonal braces 320 is fixedly connected by a clamp 340. This crosswise arrangement further enhances the overall rigidity of the support assembly 300, effectively resisting external forces in complex directions and ensuring the stability of the vibration damping base under various working conditions.

[0049] In another possible embodiment of this utility model, such as Figure 2 and Figure 3As shown, in order to ensure the stable connection between the leg column 200 and the ground of the installation area, a base plate 220 is also provided at the opposite end of the leg column 200 and the platform 100 in this embodiment. The base plate 220 is made of square or round steel plate that matches the cross-sectional shape of the leg column 200. Its length and width dimensions should be greater than the length and width dimensions of the cross-section of the leg column 200. Specifically, it should be determined according to the stress requirements of the leg column 200 and the ground conditions of the installation site.

[0050] The base plate 220 is fixed to the end of the leg column 200 by welding or bolting, ensuring a stable integral structure with the leg column 200. During installation, the base plate 220 directly contacts the ground of the installation area, increasing the contact area to distribute the pressure transmitted from the leg column 200, thereby reducing the pressure per unit area on the ground and preventing ground settlement or damage due to excessive local stress. Simultaneously, the base plate 220 enhances the friction between the leg column 200 and the ground, improving the anti-slip capability of the vibration damping base in the horizontal direction and ensuring the stability of the vibration damping base during the operation of high-precision production equipment. In actual installation, bolts can also be installed from the base plate 220 to the ground to form a fixed connection, which can be achieved by pre-embedding a connection structure in the ground; this application does not limit the scope of this application.

[0051] In one embodiment, the base plate 220 specifically comprises two panels and a damping pad sandwiched between the two panels. The damping pad is made of the same material as the vibration damping pad, utilizing the viscoelastic properties of the adhesive material to achieve vibration reduction and buffering. In this embodiment, one side panel of the base plate 220 is fixedly connected to the leg column 200, and the other side panel is fixedly connected to the ground. The damping pad sandwiched between the two panels provides elastic stability for supporting the leg column 200, absorbing some of the vibration energy transmitted from the leg column 200 to the ground, further reducing the impact of vibration on the ground. It also reduces the energy of ground vibration reaction on the leg column, making the support of the leg column more stable. This type of base plate can adapt and buffer vibrations of varying intensities through the elastic deformation of the damping pad, providing more reliable bottom support for the entire vibration-damping base. Furthermore, when encountering uneven ground, the damping pad can also play a certain adjustment role, allowing the base plate to better conform to the ground, ensuring the stability of the leg column's verticality, and thus ensuring the normal operation of the high-precision production equipment on the platform.

[0052] Furthermore, such as Figure 2 and Figure 3As shown, a mortar layer 500 is also provided on the side of the base plate 220 opposite to the leg column 200. Specifically, the mortar layer 500 is epoxy mortar. Epoxy mortar has strong adhesion to various substrates such as concrete, stone, wood, and metal. This is because epoxy resin molecules contain a large number of polar groups, which can form good chemical bonds and physical adsorption with the substrate surface. At the same time, epoxy mortar can resist corrosion from acids, alkalis, salts, chemical solvents, oils, etc. This is because the epoxy resin molecular structure contains a large number of epoxy groups and aromatic ring structures, which have high chemical stability and chemical corrosion resistance. For example, in the floors and walls of chemical plants, epoxy mortar can resist the erosion of chemical media for a long time, protecting the substrate from damage.

[0053] Furthermore, epoxy mortar possesses excellent fluidity, allowing for uniform coating onto the substrate surface and automatic leveling under gravity. Therefore, by setting a mortar layer 500, a tighter and more uniform bond can be achieved between the base plate 220 and the ground, effectively filling any unevenness or minor gaps in the ground and further enhancing the stability of the connection between the base plate 220 and the ground. Moreover, after curing, epoxy mortar exhibits high strength and hardness, capable of withstanding significant pressure transmitted from the leg column 200 without cracking or damage, providing a reliable support foundation for the vibration-damping base. Simultaneously, its excellent wear resistance ensures that even under long-term use and friction caused by equipment vibration, the surface remains flat and intact, preventing wear from affecting the connection with the ground and the overall vibration-damping performance. Additionally, epoxy mortar possesses a certain degree of elasticity, acting as a buffer when equipment vibrates, reducing the direct impact of vibration on the ground and also reducing the force of ground vibration reaction on the equipment, forming a virtuous cycle of vibration reduction and comprehensively ensuring the stability and accuracy of high-precision production equipment during operation.

[0054] In another possible embodiment of this utility model, such as Figure 2 and Figure 3 As shown, to further improve the connection stability between the base plate 220 and the leg column 200, several elbow plates 221 are spaced apart on the outer surface of the leg column 200 in this embodiment. The elbow plates 221 are right-angled triangles and are installed perpendicular to the base plate 220. One right-angled side of the elbow plate 221 is fixedly connected to the base plate 220, and the other right-angled side is fixedly connected to the leg column 200. Through its stable right-angled triangular structure, the elbow plate 221 provides additional support and fixation between the leg column 200 and the base plate 220, thereby effectively dispersing the stress transmitted from the leg column 200 to the base plate 220 and avoiding damage to the connection parts caused by stress concentration. At the same time, the elbow plates 221 also enhance the rigid connection between the leg column 200 and the base plate 220, improving the stability and reliability of the entire vibration damping base when subjected to complex external forces.

[0055] In the above embodiment, a baked enamel coating is also provided on the surface of the leg column 200. This coating not only provides the leg column 200 with an aesthetically pleasing appearance, but more importantly, it offers excellent corrosion resistance. In the operating environment of high-precision production equipment, various corrosive factors may exist, such as humid air and chemicals. The baked enamel coating forms a dense protective film, effectively isolating these corrosive factors from direct contact with the leg column 200, thereby extending its service life. Furthermore, the baked enamel coating also possesses a certain degree of wear resistance, reducing wear on the surface of the leg column 200 during daily operation and potential collisions, maintaining its structural integrity and stability. In addition, the smooth surface of the baked enamel coating does not easily accumulate dust and dirt, facilitating cleaning and maintenance, further ensuring the overall performance of the vibration damping base.

[0056] Based on the above embodiments, the actual installation process of the vibration damping base of this utility model is as follows:

[0057] First, the completed vibration damping base is transported to the installation site;

[0058] A mortar layer 500 is set on the installation ground, and then the leg column 200 is hoisted to the preset installation position. Support components 300 are installed between adjacent leg columns 200. After confirming that the installation position of the leg column 200 is correct and a fixed connection is formed, the base plate 220 of the leg column 200 is fixedly connected to the ground by bolts and other structures.

[0059] Damping and vibration-damping quartz sand 210 is filled into the interior of several leg columns 200 and sealed. Then, vibration damping pads 400 are laid on the ends of the leg columns 200. Finally, the frame 110 is hoisted and placed on the leg columns 200 and fixedly connected by bolts and other structures.

[0060] A steel mesh is laid inside the frame 110, and a concrete layer 120 is poured in. After the concrete layer 120 has completely solidified, a dustproof layer 130 is laid after the concrete layer 120 is precisely ground, thus completing the installation of the vibration damping base.

[0061] In actual use, the high-precision production equipment sits on the platform 100. The vibrations generated during the operation of the high-precision production equipment are significantly reduced through multiple vibration damping mechanisms of the vibration damping base, including energy dissipation of quartz sand particles, viscoelastic energy dissipation of rubber vibration damping pads 400, and the overall vibration resistance of the reinforced concrete structure. This allows the equipment to operate on a more stable platform, effectively reducing precision deviations caused by vibration and ensuring higher quality consistency of the produced products.

[0062] Meanwhile, the dustproof layer 130 design of the vibration damping base effectively resists the erosion of the platform 100 by corrosive substances in the external environment. The high strength, high toughness, and excellent chemical corrosion resistance of the three-layer epoxy resin anti-corrosion layer ensure that the platform 100 remains intact during long-term use, further extending the service life of the vibration damping base.

[0063] In summary, this utility model provides a vibration-damping base, which specifically includes: a platform, comprising a frame and a concrete layer poured into the frame; several legs arranged circumferentially along the edge of the platform, with one end connected to the platform, and a support assembly between adjacent legs; the legs are filled with damping and vibration-damping quartz sand; and vibration-damping pads located at the connection between the legs and the platform. This utility model uses a platform with a frame and a concrete layer to install production equipment, and supports the platform with legs filled with damping and vibration-damping quartz sand. The legs and platform are connected by vibration-damping pads. When the equipment vibrates, the damping and vibration-damping quartz sand in the legs absorbs vibration energy through mutual friction and collision, and the vibration-damping pads reduce the vibration amplitude, preventing resonance. This effectively reduces the vibration generated during equipment operation and the impact of environmental vibration on the equipment, providing a vibration-resistant foundation for the operation of high-precision equipment.

[0064] It should be understood that the application of this utility model is not limited to the examples above.
