Description

Technical Field

[0001] This utility model relates to the field of structural seismic engineering technology, and in particular to an intercolumn energy dissipation and vibration reduction device for silos. Background Technology

[0002] Silos are tall structures used to store bulk materials. They are characterized by their height and the enormous weight of the materials stored inside. Under normal use, silos mainly bear the weight of their own structure and the vertical pressure of the materials. However, in the event of natural disasters such as earthquakes, silos are subjected to horizontal seismic forces.

[0003] To improve the seismic performance of silos, inter-column energy dissipation and vibration reduction devices have emerged. Silos are typically supported by multiple columns to bear vertical loads. These columns are key load-bearing components of the silo structure. The inter-column energy dissipation and vibration reduction devices are installed between adjacent columns. Through reasonable structural design, when an earthquake occurs and the supporting columns undergo relative displacement due to seismic forces, the inter-column energy dissipation and vibration reduction devices utilize their internal energy dissipation components to consume seismic energy, converting the seismic force into other forms of energy. This reduces the vibration amplitude and displacement of the supporting columns, effectively protecting the integrity and stability of the silo structure.

[0004] In existing technologies, the structure of energy dissipation and vibration reduction devices between silo columns is usually designed to be relatively simple, and the mechanism of energy dissipation and vibration reduction is also relatively simple. The main focus of daily earthquake resistance is to add rigid structures between the supporting columns to strengthen the support stability. This method has shown some effectiveness in dealing with small earthquakes, and can control the displacement and vibration amplitude of the silo to a certain extent, ensuring the basic stability of the silo structure. However, once a large earthquake with interwoven lateral and longitudinal vibrations and complex and variable vibration characteristics is encountered, due to the simple structure and the lack of sophisticated and diverse energy dissipation components inside the device, it is difficult to absorb and convert complex seismic energy in a comprehensive and efficient manner, which leads to the risk of cracks, tilting or even collapse of the silo. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing inter-column energy dissipation and vibration reduction devices for silos have a single energy dissipation and vibration reduction method and poor energy dissipation and vibration reduction effect when dealing with large earthquakes, which endangers the structural safety of silos. Therefore, this invention proposes an inter-column energy dissipation and vibration reduction device for silos.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a column energy dissipation and vibration damping device for silos, comprising a base, a base slidably connected to the top of the base, an adaptive buffer component between the base and the base, a plurality of support columns evenly arranged on the side of the base away from the base, a symmetrical vibration damping component and a tensile energy absorption component arranged between a pair of support columns, and a fixing component arranged in the middle of the support column. The symmetrical damping component includes a housing 1, which is assembled in the middle of the support column. A housing 2 is slidably connected inside the housing 1. A housing 3 is slidably connected to the end of the housing 2 away from the housing 1. A cavitation groove is provided in the middle of the housing 2. The support column and the symmetrical damping component are connected together by a fixing component.

[0007] Preferably, the stretching energy absorption assembly includes a cylinder body one, which is assembled in the middle of the support column. A cylinder body two is slidably connected inside the cylinder body one. A spring two is fixedly connected to the end of the cylinder body two away from the cylinder body one. A connecting rod is fixedly connected to the end of the spring two away from the cylinder body two. A bolt is assembled in the middle of the cylinder body one.

[0008] Preferably, the adaptive buffer assembly includes a fixed rod, which is fixedly connected to the inside of the base, and a sliding rod is slidably connected inside the fixed rod. A compression spring is provided between the fixed rod and the sliding rod.

[0009] Preferably, the fixing component includes a fixing seat, which is fixedly connected to the outside of the support column, and a movable rod is movably connected inside the fixing seat, with a limit piece fixedly connected to the outside of the movable rod.

[0010] Preferably, the third box is assembled in the middle of the support column, the second box is provided with a wave buffer sheet, and the third box is provided with a honeycomb spring sheet.

[0011] Preferably, a spring is installed inside the first box, and the spring abuts against the first box and the second box.

[0012] Preferably, multiple bolt holes are evenly provided in the middle of the second cylinder, and bolts are threadedly connected to the middle of the bolt holes.

[0013] Preferably, a mounting base is fixedly connected to the outer side of the support column, a connecting rod is rotatably connected to the middle of the mounting base, and a deformation recording block is provided between the second cylinder and the connecting rod.

[0014] Preferably, a hole is provided in the middle of the box body, and the movable rod is slidably connected in the middle of the hole.

[0015] Preferably, the limiting piece is slidably connected to the inner wall of the fixed base, and a spring is provided between the moving rod and the limiting piece.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention proposes an inter-column energy dissipation and vibration reduction device for silos. By setting up symmetrical vibration reduction components, when the support column is affected by an earthquake and undergoes relative displacement, it drives box one, box two and box three to respond in sequence. Box two accurately guides the deformation direction with the collapse groove and dissipates energy through sliding friction with box one. At the same time, the internal wave buffer plate drives the honeycomb spring sheet of box three to work together to convert the earthquake energy into deformation energy and heat energy inside the material. This reduces the vibration impact from multiple directions, ensures the stability of the support column, and thus stabilizes the overall structure of the silo.

[0017] 2. The present invention proposes an inter-column energy dissipation and vibration reduction device for silos. By setting an adaptive buffer component, when the seismic wave causes the two to move relative to each other, the support column is forced to press the sliding rod, which drives the compression spring to contract and generate a reverse force. This effectively disperses the initial impact energy, prevents strong tremors from directly impacting the upper structure, lays a solid foundation for the stable operation of the entire device, and greatly improves the silo's ability to cope with impacts in the early stages of an earthquake.

[0018] 3. The present invention proposes an inter-column energy-dissipating and vibration-damping device for silos. By setting up a tension energy-absorbing component, when an earthquake causes the support column to shift, it drives the first and second cylinders to slide relative to each other, causing the second spring to stretch or compress, absorbing and converting part of the earthquake energy into elastic potential energy storage. Furthermore, the operator can rotate the bolt in and out of the bolt hole to change the relative distance between the first and second cylinders, causing the tension of the second spring to change. The device can be adjusted in real time according to the earthquake intensity to optimize the energy absorption effect, ensure precise buffering and vibration reduction under different earthquake magnitudes, and maintain the stability of the silo.

[0019] 4. The present invention proposes an inter-column energy-dissipating and vibration-damping device for silos. By pulling the moving rod, the limiting plate slides and compresses the spring three. After inserting into the box body one, the moving rod is released. The reaction force of the spring three causes the moving rod to insert into the hole and complete the fixation. This allows for the rapid installation or removal of symmetrical vibration-damping components between the supporting columns, effectively improving installation efficiency, reducing the labor intensity of operators, providing convenience for device maintenance and repair, and ensuring long-term reliable earthquake resistance of the silo.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

In addition, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] Please see the appendix Figure 1 -Appendix Figure 4 This utility model provides an intercolumn energy dissipation and vibration damping device for silos, including a base 1, a base 2 slidably connected to the top of the base 1, an adaptive buffer component 6 between the base 1 and the base 2, a plurality of support columns 3 evenly arranged on the side of the base 2 away from the base 1, a symmetrical vibration damping component 4 and a tensile energy absorption component 5 arranged between a pair of support columns 3, and a fixing component 7 arranged in the middle of the support column 3. The symmetrical damping component 4 includes a first housing 41, which is mounted in the middle of the support column 3. A second housing 42 is slidably connected inside the first housing 41. A third housing 43 is slidably connected to the end of the second housing 42 away from the first housing 41. A crushing groove 44 is provided in the middle of the second housing 42. The support column 3 and the symmetrical damping component 4 are connected together by a fixing component 7. The third housing 43 is mounted in the middle of the support column 3. A wave buffer 46 is provided inside the second housing 42. A honeycomb spring 47 is provided inside the third housing 43. A spring 45 is mounted inside the first housing 41. The spring 45 abuts against the first housing 41 and the second housing 42.

[0024] The displacement of the support column 3 causes the box 41 mounted on it to move synchronously, which in turn causes the box 42, which is slidably connected inside the box 41, to begin sliding. The box 42, with its centrally located collapsible groove 44, can precisely guide its deformation direction during the sliding process, allowing it to efficiently dissipate seismic energy during relative sliding friction with the box 41. Simultaneously, the wave-shaped buffer plate 46 inside the box 42 deforms under stress, working in conjunction with the honeycomb spring plate 47 inside the box 43 to gradually convert the received seismic energy into deformation energy and heat energy within the material, reducing the impact of vibration from multiple directions and providing stability for the support column 3. The system provides a certain level of support to ensure stability during earthquakes. By compressing the spring 45, some impact energy is stored, buffering the instantaneous impact of the earthquake on the device. After the earthquake impact ends, the spring 45 returns to its original position to a certain extent due to its elasticity, helping the entire symmetrical damping assembly 4 to return to a relatively stable initial state in order to cope with possible aftershocks or further strong earthquakes. This method can not only significantly reduce the vibration amplitude and displacement of the support column 3 during an earthquake, effectively protecting the integrity of the silo structure, but also quickly self-adjust during the intervals between multiple earthquake impacts, always providing reliable seismic protection for the silo and reducing maintenance costs and downtime losses caused by earthquake damage to the silo.

[0025] Please see the appendix Figure 1 Appendix Figure 5 and attached Figure 6The stretching energy absorption assembly 5 includes a first cylinder 51, which is assembled in the middle of the support column 3. A second cylinder 52 is slidably connected inside the first cylinder 51. A second spring 53 is fixedly connected to the end of the second cylinder 52 away from the first cylinder 51. A connecting rod 54 is fixedly connected to the end of the second spring 53 away from the second cylinder 52. A bolt 55 is assembled in the middle of the first cylinder 51. Multiple bolt holes 56 are evenly opened in the middle of the second cylinder 52. The bolt 55 is threadedly connected to the middle of the bolt holes 56. A mounting base 8 is fixedly connected to the outside of the support column 3. The connecting rod 54 is rotatably connected to the middle of the mounting base 8. A deformation recording block 57 is provided between the second cylinder 52 and the connecting rod 54.

[0026] As cylinder 1 (51) and cylinder 2 (52) slide relative to each other, spring 2 (53) connected to one end of cylinder 2 (52) rapidly expands and contracts with the relative sliding. Spring 2 (53), with its excellent elastic properties, absorbs some of the seismic energy and stores it as its own elastic potential energy, thus buffering the impact of the earthquake. Simultaneously, operators can loosen the bolt 55 installed in the middle of cylinder 1 (51) to bring cylinder 1 (51) and cylinder 2 (52) into a relatively fixed state, thereby adjusting their relative distance. Then, the bolt 55 is tightened again into the bolt hole 56 in the middle of cylinder 2 (52) for quick adjustment, installation, and fixation. This method adjusts the initial tightness of spring 2 (53), thereby optimizing its energy absorption effect. When facing earthquakes of different magnitudes, it flexibly adjusts its state, precisely buffering and reducing shock, ensuring the support column 3 remains relatively stable, effectively reducing the vibration amplitude and displacement of the silo structure caused by earthquakes, ensuring the structural integrity of the silo, and reducing the frequency and cost of maintenance due to earthquake disasters.

[0027] Please see the appendix Figure 7 -Appendix Figure 8 The adaptive buffer assembly 6 includes a fixed rod 61, which is fixedly connected to the inside of the base 1. A slide rod 62 is slidably connected inside the fixed rod 61, and a compression spring 63 is provided between the fixed rod 61 and the slide rod 62.

[0028] When an earthquake strikes, the support column 3 presses against the sliding rod 62, causing it to slide inside the fixed rod 61, which in turn compresses the compression spring 63. The compression spring 63 contracts under pressure, generating a counterforce through its elastic properties. This flexibly adjusts the buffering force, dispersing the initial impact energy in various directions and preventing a strong tremor from directly impacting the upper structure without buffer. This lays a solid foundation for the stable operation of the entire energy-dissipating and vibration-damping device. This step is crucial in the initial stage of an earthquake, effectively reducing the instantaneous impact force on the silo, greatly improving the stability of the silo structure in the initial earthquake phase, reducing the risk of structural damage caused by the initial strong earthquake impact, and ensuring the normal functioning of the silo's inter-column energy-dissipating and vibration-damping device.

[0029] Please see the appendix Figure 1 -Appendix Figure 4 The fixing component 7 includes a fixing seat 71, which is fixedly connected to the outside of the support column 3. A moving rod 72 is slidably connected inside the fixing seat 71. A limiting piece 74 is fixedly connected to the outside of the moving rod 72. A hole 73 is opened in the middle of the box body 41. The moving rod 72 is slidably connected to the middle of the hole 73. The limiting piece 74 is slidably connected to the inner wall of the fixing seat 71. A spring 75 is provided between the moving rod 72 and the limiting piece 74.

[0030] When the operator applies an outward force to pull the moving rod 72, the moving rod 72 is displaced under the force, which in turn causes the limiting piece 74 to move synchronously along the inner wall of the fixed base 71. The spring 75 is compressed and stores elastic potential energy. The operator aligns the box 41 with the predetermined position on the support column 3 and inserts it smoothly. After the box 41 is inserted into place, the operator releases the pulling force on the moving rod 72. At this moment, the elastic potential energy stored in the spring 75 is released instantaneously, generating a reaction force that pushes the moving rod 72 to move quickly towards the box 41 until the moving rod 72 is precisely inserted into the box 41. The central hole 73 securely fixes the housing 41, enabling quick and reliable installation of the symmetrical damping component 4 between a pair of support columns 3. When the symmetrical damping component 4 needs to be disassembled, simply repeat the operation of pulling the moving rod 72 outward to release the fixation of the housing 41 and easily remove the symmetrical damping component 4. This method effectively improves the installation and disassembly of the symmetrical damping component 4 between the support columns 3, greatly improves work efficiency, effectively reduces the labor intensity of operators, and shortens the time cost required for the installation, maintenance, and repair of the inter-column energy-dissipating damping device for silos.

[0031] Working principle: By setting an adaptive buffer between the base 1 and the base 2, when the seismic wave arrives and the base 1 and the base 2 tend to move relative to each other, the support column 3 presses the slide rod 62, which in turn squeezes the compression spring 63, flexibly adjusting the buffering force, effectively dispersing the initial impact energy, preventing strong vibrations from directly impacting the upper structure, and laying a solid foundation for the stable operation of the entire device.

[0032] When the support column 3 is affected by the earthquake and undergoes relative displacement, the first box 41, the second box 42 and the third box 43 will trigger the response in sequence. The second box 42, with the central collapse groove 44, accurately guides the deformation direction and efficiently dissipates energy during the sliding friction process. At the same time, the internal wave buffer sheet 46 and the honeycomb spring sheet 47 of the third box 43 cooperate with each other. With their special structure, they convert the earthquake energy into the deformation energy and heat energy inside the material, reduce the vibration impact in multiple directions, and ensure the stability of the support column 3. The impact is stored and buffered by the first spring (45), and a certain degree of reset is performed after the impact ends.

[0033] When an earthquake causes the support column 3 to shift, the first cylinder 51 and the second cylinder 52 slide relative to each other. The second spring 53 connected to one end of the second cylinder 52 quickly extends and retracts, absorbing some of the earthquake energy and converting it into its own elastic potential energy. Furthermore, by loosening the bolt 55 and adjusting the relative distance between the first cylinder 51 and the second cylinder 52, the bolt 55 is tightened again to the bolt hole 56 for quick adjustment, installation, and fixation. The tightness of the second spring 53 can be adjusted in real time according to the earthquake intensity, optimizing the energy absorption effect and ensuring accurate buffering and shock absorption under different earthquake magnitudes.

[0034] When installing the symmetrical damping assembly 4, the operator pulls the moving rod 72 outward. The moving rod 72 moves the limiting plate 74 and compresses the spring 3 75. At the same time, the box 1 41 is inserted into the support column 3. Then, the moving rod 72 is released. Under the reaction force of the spring 3 75, the moving rod 72 is quickly inserted into the hole 73, completing the fixation of the box 1 41. The symmetrical damping assembly 4 can be quickly and conveniently installed or removed between a pair of support columns 3, effectively improving installation efficiency and reducing the labor intensity of the operator.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
