Description

[Technical Field]

[0001] The present invention relates to a suspended seismic isolation device with a displacement suppression mechanism, and more particularly to a suspended seismic isolation device with a displacement suppression mechanism that is made up of a suspended seismic isolation member that can withstand tensile force. [Background technology]

[0002] In earthquake-prone areas, equipment, instruments, racks, stored items, etc. inside buildings are susceptible to damage due to earthquake vibrations. Therefore, seismic isolation technology used in structural engineering can prevent damage to structures and protected objects due to excessive vibration energy by mainly reducing the transmission of earthquake and other vibrations to the structures and protected objects.

[0003] Currently available seismic isolation technologies often use tilting or sliding support devices. The impact of vibrations on the protected object is mitigated by the use of rotating or sliding mechanisms within the support structure and additional energy dissipation mechanisms such as liquid dampers, friction dampers, or lateral friction plates. However, these support technologies are currently installed on the underside of the target structure. The support devices can withstand gravity loads and, in the event of an earthquake, can block seismic energy, significantly reduce the transmission of vibrations to the protected object, reduce the acceleration and displacement of the protected object, and mitigate earthquake damage. However, existing support devices are limited to pressure-resistant designs, and therefore cannot provide effective seismic isolation for ceiling-mounted equipment or suspended transportation systems.

[0004] In view of the above circumstances, the present invention proposes a suspended seismic isolation device with a displacement suppression mechanism to solve the problem that the conventional technology is unable to provide effective seismic isolation function for suspended equipment or suspended transportation systems. Summary of the Invention

[0005] The present invention provides a suspended seismic isolation device with a displacement suppression mechanism and a suspended seismic isolation system with a displacement suppression mechanism. The suspended seismic isolation device with a displacement suppression mechanism is composed of two horizontal unidirectional tension-type support modules. Cooperation between the fixed and movable members of the support module allows the support module to self-restore after vibration. The support module also includes a displacement suppression module, which suppresses earthquake-induced displacement and reduces the space required for seismic isolation. The suspended seismic isolation system with a displacement suppression mechanism is composed of multiple suspended seismic isolation devices with displacement suppression mechanisms connected in parallel, enabling systematic seismic isolation for large suspended equipment and irregularly shaped protected objects. Therefore, the suspended seismic isolation device with a displacement suppression mechanism and the suspended seismic isolation system with a displacement suppression mechanism protect the suspended object from vibration. Furthermore, by using this seismic isolation device or system inside a structure, it is possible to balance mass and reduce the vibration response when the structure encounters an earthquake.

[0006] To achieve the above object, the present invention provides a suspended seismic isolation device with a displacement suppression mechanism, comprising a first support module, a second support module, a first displacement suppression module, and a second displacement suppression module.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The present invention will be described below through examples. Note that the examples of the present invention are merely examples of embodiments and are not intended to limit the present invention to the environments, applications, or specific aspects described in the examples. Therefore, the description of the embodiments is intended to explain the present invention, but is not intended to limit the present invention. Note that components not directly related to the present invention are omitted and not shown in the embodiments and drawings. The dimensional relationships between the components in the drawings are intended to facilitate understanding and are not intended to limit the actual dimensions.

[0019] 1, 2, and 8 show a suspended seismic isolation system 1000 with a displacement suppression mechanism. FIGS. 1 and 2 are a schematic diagram and a side view, respectively, of the suspended seismic isolation system 1000 with a displacement suppression mechanism according to an embodiment of the present invention. FIG. 8 is a schematic diagram showing a simulation of the suspended seismic isolation system 1000 with a displacement suppression mechanism according to an embodiment of the present invention and the prior art. The suspended seismic isolation system 1000 with a displacement suppression mechanism according to the present invention comprises a first support module 1, a second support module 2, a first displacement suppression module 3, and a second displacement suppression module 4, and is used to suspend an object 2000. The first support module 1 and the second support module 2 are stacked perpendicularly one above the other. The first support module 1 is a structure for mounting on a ceiling or roof. The second support module 2 is connected to the suspended object 2000. The first displacement suppression module 3 is attached to the first support module 1. The second displacement suppression module 4 is attached to the second support module 2. The first displacement suppression module 3 and the second displacement suppression module 4 enable the first support module 1 and the second support module 2 to absorb vibrations and suppress displacement. As shown in Figure 8, A and B respectively represent a reinforcement technique and a general suspension technique for suspending an object in the prior art. C represents the suspended seismic isolation device with a displacement suppression mechanism of the present invention, which is attached by hanging from any fixed end above. The difference between the present invention and the prior art can be clearly seen from the figure.

[0020] First, the first support module 1 will be described. FIG. 3 is a partial perspective view showing a suspended seismic isolation device 1000 with a displacement suppression mechanism. The first support module 1 has a first fixed member 11, a first movable member 12, and two first rollers 13. Note that there is no particular limit to the number of first rollers 13 as long as it is within the scope of the technical concept disclosed in this application. The number of first rollers 13 may be two, three, four, or more. The first fixed member 11 and the first movable member 12 cooperate with each other. The first roller 13 is sandwiched between the first fixed member 11 and the first movable member 12. When the first movable member 12 moves in a first direction D1 relative to the first fixed member 11, the first roller 13 rolls along the first direction D1. The first fixed member 11 has four first extension arms 111, two first horizontal arms 112, and two first side panels 113. The first extension arms 111 are installed at both ends of the first fixed member 11 in the device movement direction. Each pair of first extension arms 111 is connected by a first horizontal arm 112. The first horizontal arm 112 is connected to the two first extension arms 111 on the same side. The first side plates 113 are connected to the first fixed member 11 and sandwich the left and right sides of the first roller 13, thereby protecting the first roller 13 from the sides, restricting the first roller 13 to roll along the first direction D1, and preventing the first roller 13 from coming off. The first horizontal arm 112 further includes a first upper rack 1121 and a first guide portion 1122. The first upper rack 1121 is formed on the inner surface (top surface) of the first horizontal arm 112. The first guide portion 1122 is formed on the outer surface of the first horizontal arm 112.

[0021] As shown in FIGS. 1 to 3, the first movable member 12 has two second extension arms 121 and a second horizontal arm 122. The second extension arms 121 are installed at both ends of the first movable member 12 in the device movement direction. The second horizontal arm 122 is connected to the two second extension arms 121. A pair of second extension arms 121 is connected by the second horizontal arm 122. More specifically, the first extension arm 111 and the first horizontal arm 112 of the first fixed member 11 and the second extension arm 121 and the second horizontal arm 122 of the first movable member 12 are arranged alternately. As shown in FIG. 1, the second extension arm 121 is located between the two first extension arms 111. The second horizontal arm 122 further has a first lower rack 1221. The first lower rack 1221 is formed on the inner surface (lower surface) of the second horizontal arm 122. At least one of the vertical inner surface (upper surface) of the first horizontal arm 112 and the vertical inner surface (lower surface) of the second horizontal arm 122 is non-planar. The first roller 13 is sandwiched between the first horizontal arm 112 of the first fixed member 11 and the second horizontal arm 122 of the first movable member 12. When the first movable member 12 moves relative to the first fixed member 11, the first roller 13 rolls between the first horizontal arm 112 and the second horizontal arm 122 along the first direction D1. For example, in this embodiment, the inner surface (upper surface) of the first horizontal arm 112 and the inner surface (lower surface) of the second horizontal arm 122 are both non-planar. The non-planar surface may be a curved surface, a V-shaped inclined surface, or a surface designed by an arbitrary mathematical function. The main purpose of the non-planar design is to enable the first roller 13 to self-return after rolling due to vibration. Therefore, in either case, when only the inner surface (upper surface) of the first horizontal arm 112 is designed to be non-flat, or when only the inner surface (lower surface) of the second horizontal arm 122 is designed to be non-flat, the first roller 13 can return to its original position by itself. This specification does not particularly limit the scope of the present invention.

[0022] As shown in FIG. 1 , in this embodiment, each first roller 13 has three first gears 131. The first gears 131 are installed on the first roller 13 at positions corresponding to the two first upper racks 1121 and the first lower rack 1221. Each first gear 131 meshes with the corresponding first upper rack 1121 and first lower rack 1221. When the suspended seismic isolation device 1000 with a displacement suppression mechanism is subjected to an external force, the first roller 13 rolls on the first upper rack 1121 and the first lower rack 1221 via the first gears 131. Cooperation between the gears and the racks can regulate the first roller 13. The number of first gears 131 can be adjusted according to actual needs, depending on the number of first upper racks 1121 and first lower racks 1221. This specification does not particularly limit the number of first gears 131.

[0023] Specifically, the purpose of the first horizontal arms 112 of the first fixed member 11 and the second horizontal arms 122 of the first movable member 12 being arranged alternately above and below is to sandwich the first roller 13. Another purpose is to regulate the first roller 13 so that it can roll stably. Therefore, in this embodiment, when the number of first horizontal arms 112 is one, the number of second horizontal arms 122 is more than one. Conversely, when the number of second horizontal arms 122 is one, the number of first horizontal arms 112 is more than one. Alternatively, the numbers of both first horizontal arms 112 and second horizontal arms 122 are more than one. The numbers can be changed according to actual needs and are not limited here.

[0024] Next, the second support module 2 will be described. As shown in FIGS. 1 and 5, the second support module 2 has a second fixed member 21, a second movable member 22, and two second rollers 23. There is no particular limitation on the number of second rollers 23 as long as it is within the scope of the technical concept disclosed in this application. The number of second rollers 23 may be two, three, four, or more. The second fixed member 21 and the second movable member 22 cooperate with each other. The second roller 23 is sandwiched between the second fixed member 21 and the second movable member 22. When the second movable member 22 moves in the second direction D2 relative to the second fixed member 21, the second roller 23 rolls along the second direction D2. The second fixed member 21 has four third extension arms 211, two third horizontal arms 212, and two second side panels 213. The third extension arms 211 are installed at both ends of the second fixed member 21 in the device movement direction. Each pair of third extension arms 211 is connected by a third horizontal arm 212. The third horizontal arm 212 is connected to the two third extension arms 211 on the same side. The second side plates 213 are connected to the second fixed member 21 and sandwich the left and right sides of the second roller 23, thereby protecting the second roller 23 from the sides and restricting the second roller 23 to roll along the second direction D2, preventing the second roller 23 from coming off. Furthermore, the third horizontal arm 212 further has a second upper rack 2121 and a second guide portion 2122. The second upper rack 2121 is formed on the inner surface (top surface) of the third horizontal arm 212. The second guide portion 2122 is formed on the outer surface of the third horizontal arm 212.

[0025] Specifically, the second movable member 22 has two fourth extension arms 221 and a fourth horizontal arm 222. The fourth extension arms 221 are installed at both ends of the second movable member 22 in the device movement direction. The fourth horizontal arm 222 is connected to the two fourth extension arms 221. A pair of fourth extension arms 221 is connected by the fourth horizontal arm 222. Specifically, the third extension arm 211 and the third horizontal arm 212 of the second fixed member 21 and the fourth extension arm 221 and the fourth horizontal arm 222 of the second movable member 22 are arranged alternately. As shown in FIG. 1 , the fourth horizontal arm 221 is located between the two third extension arms 211. The fourth horizontal arm 222 further has a second lower rack 2221. The second lower rack 2221 is formed on the inner surface (lower surface) of the fourth horizontal arm 222. At least one of the vertical inner surface (upper surface) of the third horizontal arm 212 and the vertical inner surface (lower surface) of the fourth horizontal arm 222 is non-planar. The second roller 23 is sandwiched between the third horizontal arm 212 of the second fixed member 21 and the fourth horizontal arm 222 of the second movable member 22. When the second movable member 22 moves relative to the second fixed member 21, the second roller 23 rolls between the third horizontal arm 212 and the fourth horizontal arm 222 along the second direction D2. For example, in this embodiment, the inner surface (upper surface) of the third horizontal arm 212 and the inner surface (lower surface) of the fourth horizontal arm 222 are both non-planar. The non-planar surface may be a curved surface, a V-shaped inclined surface, or a surface designed by an arbitrary mathematical function. The main purpose of the non-planar design is to enable the second roller 23 to self-return after rolling due to vibration. Therefore, in either case, when only the inner surface (upper surface) of the third horizontal arm 212 is designed to be non-flat, or when only the inner surface (lower surface) of the fourth horizontal arm 222 is designed to be non-flat, the second roller 23 can return to its original position by itself. This specification does not particularly limit the scope of the present invention.

[0026] As shown in FIG. 4 , in this embodiment, each second roller 23 has three second gears 231. The second gears 231 are installed on the second roller 23 at positions corresponding to the two second upper racks 2121 and the two second lower racks 2221. Each second gear 231 meshes with the corresponding second upper rack 2121 and second lower rack 2221. When the suspended seismic isolation device 1000 with a displacement suppression mechanism is subjected to an external force, the second roller 23 rolls on the second upper rack 2121 and the second lower rack 2221 via the second gears 231. Cooperation between the gears and the racks can regulate the second roller 23. The number of second gears 231 can be adjusted according to actual needs, depending on the number of second upper racks 2121 and second lower racks 2221. This specification does not particularly limit the number of second gears 231.

[0027] Specifically, the purpose of the third horizontal arm 212 of the second fixed member 21 and the fourth horizontal arm 222 of the second movable member 22 being arranged alternately above and below is to sandwich the second roller 23. Another purpose is to regulate the second roller 23 so that it can roll stably. Therefore, in this embodiment, when the number of third horizontal arms 212 is one, the number of fourth horizontal arms 222 is more than one. Conversely, when the number of fourth horizontal arms 222 is one, the number of third horizontal arms 212 is more than one. Alternatively, the number of third horizontal arms 212 and the number of fourth horizontal arms 222 are both more than one. The number can be changed according to actual needs and is not limited here.

[0028] In this embodiment, the suspended seismic isolation device 1000 with a displacement suppression mechanism according to the present invention is configured by stacking a first support module 1 and a second support module 2 vertically, with the first support module 1 aligned along a first direction D1 and the second support module 2 aligned along a second direction D2 perpendicular to the first direction D1. The first movable member 12 is connected to a second fixed member 21, and the second movable member 22 is connected to an object 2000. When subjected to an external force, the suspended seismic isolation device 1000 with a displacement suppression mechanism can absorb the external force in both the first direction D1 and the second direction D2. In other words, the seismic isolation effect can be achieved in all horizontal directions. The first direction D1 is perpendicular to the second direction D2.

[0029] Next, the first displacement suppression module 3 and the second displacement suppression module 4 will be described. The first displacement suppression module 3 is connected to the first fixed member 11 and the first movable member 12 and suppresses displacement of the first movable member 12 along the first direction. The first displacement suppression module 3 has a first main body 31, a first movable gear 32, and a first vertical shaft 33. The first vertical shaft 33 is installed within the first main body 31 and the first movable gear 32 and is fixed to the first movable member 12. The first movable gear 32 faces the outer surface of the first horizontal arm 112 and meshes with the first guide portion 1122. The second displacement suppression module 4 is connected to the second fixed member 21 and the second movable member 22 and suppresses displacement of the second movable member 22 along the second direction D2. The second displacement suppression module 4 has a second main body 41, a second movable gear 42, and a second vertical shaft 43. The second vertical shaft 43 is installed within the second body 41 and the second movable gear 42, and is fixed to the second movable member 22. The second movable gear 42 faces the outer surface of the third horizontal arm 212 and meshes with the second guide portion 2122.

[0030] Specifically, the first displacement suppression module 3 and the second displacement suppression module 4 are friction dampers, liquid viscous dampers, or flywheel inertial mass dampers. In this embodiment, the first displacement suppression module 3 and the second displacement suppression module 4 are each flywheel inertial mass dampers. When the suspended seismic isolation device 1000 with a displacement suppression mechanism receives an external force and vibrates, the first support module 1 and the second support module 2 are displaced laterally by the external force. The first movable gear 32 and the second movable gear 42 are movable on the first guide portion 1122 and the second guide portion 2122, respectively. The inertial mass generated by the rotation of the flywheel can reduce transmitted vibration. In addition, taking into consideration the stability of the entire structure and the vibration reduction effect, the first displacement suppression module 3 and the second displacement suppression module 4 are each four in number as an example. However, the number and type can be changed according to actual needs and are not limited thereto.

[0031] The following description will be given with reference to Figures 6 to 8. Figures 6 and 7 are schematic diagrams showing the relationship between displacement and acceleration of a suspended-type seismic isolation device 1000 with a displacement suppression mechanism according to an embodiment of the present invention. As can be seen from the figures, under the action of shaking and vibrations of different dimensions, compared to the reinforcement method (A) and the general method (B) used in conventional suspended-type seismic isolation technology, the suspended-type seismic isolation device 1000 with a displacement suppression mechanism according to the present invention (C) maintains acceleration within a certain range even with the same displacement, and can significantly reduce the transmission of vibration to the suspended-type seismic isolation device 1000 with a displacement suppression mechanism according to the present invention. In this way, it can be proven that the present invention has a superior seismic isolation effect compared to conventional suspended-type seismic isolation technology.

[0032] This embodiment also provides a suspended seismic isolation system with displacement suppression mechanisms, which is composed of multiple suspended seismic isolation devices 1000 with displacement suppression mechanisms connected in parallel by connecting members. A suspended seismic isolation system with displacement suppression mechanisms configured by connecting devices in parallel can significantly increase the contact area with the object 2000, making it possible to provide systematic seismic isolation functions for large-scale suspended equipment, suspended transportation systems, and objects 2000 that are heavy, large-area, and irregularly shaped. There is no particular limit to the number of suspended seismic isolation devices with displacement suppression mechanisms connected in parallel, as long as it is within the scope of the technical concept disclosed in this application. Examples of the number of suspended seismic isolation devices with displacement suppression mechanisms include multiple numbers, such as two, three, and four.

[0033] As described above, the suspended seismic isolation device with displacement suppression mechanism according to the present invention comprises two support modules, one horizontal and one vertical, and a displacement suppression module connected to the support modules. The suspended seismic isolation device with displacement suppression mechanism reduces the vibration transmitted to the device when it vibrates due to an external force and can self-restore after the vibration. Therefore, the suspended seismic isolation device with displacement suppression mechanism can provide stable seismic isolation function in a 360-degree space. Furthermore, a suspended seismic isolation system with displacement suppression mechanism, configured by connecting multiple suspended seismic isolation devices with displacement suppression mechanisms in parallel, can enhance the earthquake resistance of large suspended equipment and suspended transportation systems.

[0034] The above examples are intended to explain embodiments of the present invention and to explain the characteristic configurations of the present invention. The present invention is not limited to the above examples. Modifications or equivalent arrangements that can be easily made by those skilled in the art are also within the scope of the present invention. The scope of protection of the rights of the present invention is based on the claims. [Explanation of symbols]
