Description

Technical Field

[0001] The invention relates to the field of engineering structure seismic isolation control, and in particular to a combined multi-directional rolling energy-absorbing metal damper device. Background Art

[0002] Rolling energy dissipation metal dampers (such as U-type dampers, C-type dampers and V-type dampers) have excellent energy dissipation characteristics and are widely used in the field of seismic isolation control technology for engineering structures. This type of metal damper is often used as a one-way energy dissipation metal damper, and is usually directly fixed to the energy dissipation node by bolts or welding. As the performance of this type of damper is widely recognized, its application field continues to expand.

[0003] Since bridges and building structures have different inherent characteristics in three directions of space, the dampers in the prior art cannot solve the problem of different energy consumption parameters in three directions of space. Publication number: CN213233115U A metal damper device capable of three-way deformation includes at least two metal dampers, the upper part of the metal damping unit is used to be fixedly connected to the bridge beam, the lower connecting plate is used to be fixedly connected to the bridge pier, the metal damping unit in at least one metal damper slides with the lower connecting plate along the longitudinal bridge direction, and the metal damping unit in at least one of the remaining metal dampers slides with the lower connecting plate along the transverse bridge direction. This structure can realize the function of shear deformation of the metal damper in three directions without interfering with each other. However, this scheme requires at least two or more metal dampers, and the two metal dampers need to be connected to the bridge beam and the pier respectively. The metal damper is easy to interfere with the tensile plate in the horizontal deformation movement when bearing vertical loads. At the same time, the space requirement is large and the installation is inconvenient.

[0004] Therefore, how to use this type of damper at a node to achieve energy dissipation in any direction in the horizontal plane and avoid interference with the tensile plate when the metal damper is compressed and rolled and deformed becomes an urgent problem to be solved. Summary of the invention

[0005] In view of this, the present invention aims to propose a combined multi-directional rolling energy-absorbing metal damper device to solve the problem that a single metal energy-absorbing damper can dissipate energy in any direction in the horizontal plane while avoiding interference with the tensile plate when the metal damper is compressed and rolled and deformed.

[0006] In the prior art, two or more metal dampers are placed in different directions to achieve energy dissipation in any direction in the horizontal plane. The two metal dampers are arranged as an integral structure, sharing the upper and lower connecting plates. In order to enable the upper connecting plate to move in any direction in the horizontal plane, the present application proposes a new guide device, which adopts four groups of I-shaped sliders combined with an embracing guide plate, so that it is possible to combine multiple one-way dampers for parallel coupling.

[0007] The traditional coupled one-way energy-absorbing damper motion bracket is a T-shaped slider plus an embracing guide plate. There is a problem with the prior art. As a rolling energy-absorbing metal damper, it will roll forward when it deforms to dissipate energy. Due to the effect of the bending moment, the damper will be pressed onto the embracing guide plate. When the damper needs to slide freely along the guide groove, the damper will be affected by the friction between the damper and the embracing plate, causing the damper to twist perpendicular to the main energy dissipation direction (rolling direction). The damper cannot roll and deform smoothly, which seriously affects its energy dissipation performance. The present application changes the T-shaped slider into an I-shaped slider. The I-shaped embedded flat plate slides inside the embracing guide plate, and the I-shaped exposed flat plate slides on the top of the embracing guide plate. The U-shaped metal damper rolls on the upper part of the exposed flat plate, and will not cause motion interference with the embracing plate.

[0008] Since simply changing the T-shaped structure to an I-shaped structure will increase the height of the structure and increase the cost of the structure, and in the prior art, when the metal damper rolls and deforms, the T-shaped slider generates a lateral torque after being stressed, and the flange of the T-shaped slider exerts a force on the tensile structure of the surrounding plate. At this time, the top of the tensile structure of the surrounding plate is infinite and is in a cantilever beam state. In order to improve the stability of the structure, the general design will increase the thickness of the tensile structure of the surrounding plate. In order to solve the problem that the I-shaped structure will increase the height of the structure, the present application reduces the plate thickness at the tensile structure of the surrounding plate, and divides the I-shaped structure into two parts, which are an exposed translation slide plate and an embedded T-shaped slider. The I-shaped structure is connected as a whole by bolts, and prestress is applied to increase the constraints around the tensile structure of the surrounding plate, and the stress state of the tensile structure of the surrounding plate is changed from a cantilever beam state to a cantilever beam state with a supporting capacity at the bottom. The height of the structure will not be increased under the premise of changing the thickness of the tensile structure. That is, when the sum of the thickness of the flange of the improved T-type slider and the thickness of the Kara mechanism plate is less than or equal to the thickness of the Kara mechanism plate of the original structure, the overall structure can still meet the requirements of structural stability and reliability.

[0009] The technical solution of the present invention is implemented as follows: a combined multi-directional rolling energy-absorbing metal damper device comprises a first motion coupling bracket, a metal damper and a second motion coupling bracket which are arranged in sequence from bottom to top;

[0015] Furthermore, the base is in the shape of a plate, a groove is provided at the bottom of the base, and a through hole is provided in the groove of the base for conveniently connecting the first guide plate assembly or the second guide plate assembly.

[0016] Furthermore, the first guide plate assembly includes two first guide plates, a first slider and a limit block, the cross-section of the first guide plate is an inverted L-shape, the cross-section of the first slider is an I-shape, the two first guide plates are relatively arranged on both sides of the waist plate of the first slider, and are used to guide the first slider to slide between the two first guide plates, and the limit block is used to limit the displacement of the first slider.

[0017] Furthermore, the first sliding block includes a flat plate and a T-shaped plate, and the flat plate is connected to the web of the T-shaped plate by bolts.

[0018] Furthermore, the metal damper is a rolling deformation energy dissipation metal damper, and the metal damper is one of a U-type, a C-type and a V-type damper.

[0019] Furthermore, the metal damper is connected to the T-shaped plate via the bolts and the pressure plate.

[0020] Furthermore, a plurality of metal-non-metal friction pairs are arranged between the first sliding block and the first guide plate, and upper and lower flanges of the first sliding block are respectively in close contact with upper and lower surfaces of horizontal portions of the two first guide plates.

[0021] Compared with the prior art, the combined multi-directional rolling energy-absorbing metal damper device of the present invention has the following advantages:

[0022] 1. The present invention proposes a new type of guide device, which adopts four groups of I-shaped sliders combined with an embracing tensile guide plate to connect two unidirectional energy dissipation dampers in the prior art into an integrated structure, thereby solving the problem that the unidirectional energy dissipation damper can only dissipate energy in one direction, and realizing that the damper can be deformed and dissipate energy in any direction in the horizontal plane, and the installation process is simple and convenient.

Under the premise that the T-shaped slider is changed to an I-shaped slider, the structure height will not be increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the technical means, objectives and effects of the present invention easy to understand, the embodiments of the present invention are described in detail below with reference to specific drawings.

[0032] It should be noted that all the terms used in the present invention to indicate directionality and positionality, such as "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside", "top", "lower", "lateral", "longitudinal", "center", etc., are only used to explain the relative positional relationship and connection status between the components in a certain state, and are only for the convenience of describing the present invention, rather than requiring the present invention to be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention.

[0035] The working direction of the metal damper 2 is the direction in which it can produce plastic deformation and consume energy when subjected to external force.

[0036] The sliding direction of the metal damper 2 is the direction in which the second motion coupling bracket 3 is relatively displaced with the metal damper 2 when the second motion coupling bracket 3 is subjected to a force perpendicular to the working direction.

[0037] The guiding directions of the first guide plate assembly 102 , the second guide plate assembly 103 , the third guide plate assembly 302 and the fourth guide plate assembly 303 are directions in which the metal damper 2 can slide on the first guide plate assembly 102 .

[0038] "Metal-non-metal friction pair" refers to the friction interface composed of metal materials and non-metal materials (such as polymers, rubber, ceramics, etc.). These materials generate friction during relative motion and have specific energy dissipation and wear characteristics, which can enable the beam to slide normally during normal temperature rise or temperature drop. The friction coefficient of the friction surface is reduced and is generally less than 0.03.

[0039] The invention discloses a combined multi-directional rolling energy-absorbing metal damper device, comprising

[0040] The first motion coupling bracket 1, the metal damper 2 and the second motion coupling bracket 3 are arranged in sequence from bottom to top;

[0041] The first kinematic coupling bracket 1 and the second kinematic coupling bracket 3 have the same structure, and the first kinematic coupling bracket 1 and the second kinematic coupling bracket 3 are symmetrically arranged, so as to enable the metal damper 2 to slide relative to the first kinematic coupling bracket 1 and the second kinematic coupling bracket 3 without interfering with the first kinematic coupling bracket 1;

[0042] The two ends of the metal damper 2 are respectively connected to the first motion coupling bracket 1 and the second motion coupling bracket 3. At least two metal dampers 2 are provided. The working directions of the two or more metal dampers 2 are set to two directions perpendicular to each other. The working direction of the metal damper 2 is perpendicular to the sliding direction of the metal damper 2.

[0043] When the structure is subjected to external dynamic effects such as earthquakes and wind, the metal damper 2 absorbs and consumes energy through plastic deformation, thereby reducing the dynamic load transmitted to the building or structure; due to the use of transverse and longitudinal guide plate components, the two one-way energy-absorbing dampers in the prior art are connected into an integrated structure, which solves the problem that the one-way energy-absorbing damper can only consume energy in one direction, and realizes that the damper can deform and consume energy in any direction in the horizontal plane. The device can provide effective energy dissipation in multiple directions and enhances the adaptability to external forces in different directions; the symmetrical design of the first motion coupling bracket 1 and the second motion coupling bracket 3 ensures that when the structure undergoes relative displacement, it can effectively transmit the motion to the metal damper 2 to realize its energy-absorbing function and ensure the stability and reliability of the entire system.

[0044] The presence of the first motion coupling bracket 1 and the second motion coupling bracket 3 divides the metal damper 2 into two working directions, which can effectively cope with forces from multiple directions, provide more comprehensive protection, ensure uniform distribution of force, and improve the stability of the system and the consistency of response.

[0045] Specifically, the first motion coupling bracket 1 includes a base 101, a first guide plate assembly 102 and a second guide plate assembly 103, the guiding direction of the first guide plate assembly 102 is perpendicular to the guiding direction of the second guide plate assembly 103, and the first guide plate assembly 102 and the second guide plate assembly 103 are arranged on the base 101.

[0046] The first guide plate assembly 102 is provided with a lateral guiding direction, and the second guide plate assembly 103 is provided with a longitudinal guiding direction. The first guide plate assembly 102 and the second guide plate assembly 103 respectively provide guiding functions in two mutually perpendicular directions, so that the coupling bracket can simultaneously handle lateral and longitudinal relative displacements.

[0047] The base 101 provides a stable foundation for the entire coupling bracket, ensures the stability of the guide plate assembly during operation, and can evenly transmit forces from different directions to the bottom structure.

[0048] This setting optimizes the layout between the base 101 and the guide plate assembly. The precisely manufactured first guide plate assembly 102 and second guide plate assembly 103 can ensure the linearity and accuracy of the movement, and can achieve efficient multi-directional motion control in a limited space. It is suitable for applications in space-constrained occasions. The prefabricated guide plate assembly can be directly installed on the base 101, simplifying the on-site assembly process; at the same time, the modular design is also conducive to later inspection and maintenance.

[0049] Specifically, a plurality of metal-non-metal friction pairs are arranged between the internal parts of the first motion coupling bracket 1 .

[0050] Specifically, the first guide plate assembly 102 and the second guide plate assembly 103 have the same structure.

[0051] The first guide plate assembly 102 and the second guide plate assembly 103 are completely consistent in size, shape, material selection and manufacturing process. They are respectively arranged on the base 101, and the working directions are perpendicular to each other, ensuring that the movements in different directions are coordinated and consistent, avoiding unexpected movements due to differences between components, and improving the operating stability of the entire system. At the same time, they handle relative displacements in both the lateral and longitudinal directions and provide comprehensive motion control capabilities. This arrangement not only simplifies the design and manufacturing process, but also allows them to be replaced with each other when necessary, increasing the flexibility of the system and reducing the difficulty of installation, because the installers only need to be familiar with one type of component to complete all installation tasks, reducing training time and error rate, and facilitating standardized production and batch procurement, thereby reducing production costs and improving economic benefits.

[0052] This setup uses identical materials and technical specifications, so the performance differences between the two components are minimal, which increases the reliability and service life of the entire system.

[0053] Specifically, the second motion coupling bracket 3 includes an upper seat plate 301, a third guide plate assembly 302 and a fourth guide plate assembly 303, the guiding direction of the third guide plate assembly 302 is perpendicular to the guiding direction of the fourth guide plate assembly 303, and the third guide plate assembly 302 and the fourth guide plate assembly 303 are arranged on the upper seat plate 301.

[0054] The third guide plate assembly 302 and the fourth guide plate assembly 303 respectively provide guiding functions in two mutually perpendicular directions, so that the coupling bracket can handle relative displacements from different directions, and work in conjunction with the first motion coupling bracket 1 to consume energy through the deformation of a metal damper 2 to reduce the impact of external power on the entire system, especially in situations such as earthquakes or strong winds. The other metal damper 2 slides in the third guide plate assembly 302 or the fourth guide plate assembly 303.

[0055] The upper seat plate 301 serves as the base of the coupling bracket, provides a stable installation platform for the entire device, and ensures effective connection with the upper structure or component.

[0056] This arrangement can achieve efficient multi-directional motion control in a limited space and is suitable for applications where space is limited. The prefabricated guide plate assembly can be directly installed on the base 101, simplifying the on-site assembly process. At the same time, the modular design is also conducive to later inspection and maintenance.

[0057] Specifically, the metal damper 2 includes a first metal damper 201 and a second metal damper 202, the two ends of the first metal damper 201 are respectively connected to the first guide plate assembly 102 and the third guide plate assembly 302, the two ends of the second metal damper 202 are respectively connected to the second guide plate assembly 103 and the fourth guide plate assembly 303, and the working direction of the first metal damper 201 is set perpendicular to the working direction of the second metal damper 202.

[0058] The first metal damper 201 connects the first guide plate assembly 102 and the third guide plate assembly 302, and the second metal damper 202 connects the second guide plate assembly 103 and the fourth guide plate assembly 303, thereby realizing bidirectional symmetrical protection of the structure and enhancing the stability and reliability of the system. The first metal damper 201 and the second metal damper 202 respectively handle relative displacements in two mutually perpendicular directions, namely, transverse and longitudinal directions. When the first metal damper 201 is working, the first metal damper 201 absorbs and consumes energy through plastic deformation, and the second metal damper 202 slides in the second guide plate assembly 103 and the fourth guide plate assembly 303, thereby preventing the second metal damper 202 from being subjected to torque in the non-working direction.

[0059] Specifically, the base 101 is in a plate shape, a groove is provided at the bottom of the base 101 , and a through hole is provided in the groove of the base 101 for conveniently connecting the first guide plate assembly 102 or the second guide plate assembly 103 .

[0060] The groove provides an accurate installation position for the first guide plate assembly 102 and the second guide plate assembly 103, ensures the accuracy during assembly, and reduces assembly errors. The through hole is located inside the groove, which can effectively protect the through hole from external environmental factors such as dust and moisture, and prevent the through hole from being damaged during transportation or construction. It can also provide sufficient embedding depth without increasing the overall height, facilitate the stable connection between the internal parts of the first guide plate assembly 102 or the second guide plate assembly 103, adjust the distance between the upper and lower flanges and apply preload.

[0061] This setting improves the durability and reliability of the entire device, makes the product surface neater and smoother, enhances the visual effect and professionalism of the product, and helps maintain the integrity of the structure.

[0062] Specifically, an eighth friction portion 1011 is provided on a side of the base 101 away from the bridge pier, for forming a bottom friction pair with the first guide plate assembly 102 or the second guide plate assembly 103 .

[0063] The eighth friction part 1011 forms a bottom friction pair with the first guide plate assembly 102 or the second guide plate assembly 103, thereby reducing direct impact and wear between components and extending the service life of the guide plate assembly and other related parts.

[0064] Preferably, the eighth friction portion 1011 is made of stainless steel.

[0065] Stainless steel materials usually have high mechanical strength and wear resistance, can withstand large loads without deformation or wear, and ensure that the friction pair can maintain good contact surface quality even in frequent relative movements, thereby ensuring the stability and reliability of the system, significantly extending the service life of the friction pair and even the entire damper system, reducing replacement frequency, and improving economic benefits. In addition, high-quality stainless steel materials usually have a good surface finish, which helps to reduce the friction coefficient, making the guide plate assembly smoother during sliding, reducing unnecessary energy loss, and at the same time reducing the torque of the upper seat plate 301 relative to the metal damper 2 or the base 101 relative to the metal damper 2, which helps to improve structural stability and reliability.

[0066] Specifically, the first guide plate assembly 102 includes two first guide plates 1021 and a first slider 1022. The cross-section of the first guide plate 1021 is an inverted L-shape, and the cross-section of the first slider 1022 is an I-shape. The two first guide plates 1021 are relatively arranged on both sides of the waist plate of the first slider 1022 to guide the first slider 1022 to slide between the two first guide plates 1021.

[0067] The inverted L-shaped first guide plate 1021 is combined with the I-shaped first slider 1022 to ensure that the slider can only move in a straight line along a predetermined path, providing a high-precision guiding function and avoiding unnecessary lateral displacement or rotation. Since the waist of the first slider 1022 is clamped between the two first guide plates 1021, this increases the stability of the system and reduces the shaking or tilting of the slider during sliding.

[0068] The setup’s precise guidance and stable support improve the system’s overall reliability, especially in extreme situations such as earthquakes, helping to maintain structural integrity and protect the building’s safety.

[0069] Specifically, a threaded hole is provided on the vertical portion of the first guide plate 1021 along the vertical direction for connecting the first guide plate 1021 and the base 101 .

[0070] The threaded holes and fasteners in the vertical direction can effectively prevent the first guide plate 1021 from unnecessary sliding on the horizontal plane, especially when subjected to lateral forces, thereby maintaining the stability and reliability of the system.

[0071] The reasonable threaded hole layout can hide the bolt head, making the product surface neater and smoother, improving the visual effect and professionalism of the product. The threaded connection method is simple and intuitive, easy to operate, does not require complicated tools or special skills, and can speed up installation and improve work efficiency.

[0072] Specifically, the first sliding block 1022 includes a flat plate 10221 and a T-shaped plate 10222 , and the flat plate 10221 and the web of the T-shaped plate 10222 are connected by bolts.

[0073] The separate design of the flat plate 10221 and the T-plate 10222 allows the components to be processed separately during the manufacturing process, thereby improving production efficiency and quality control and facilitating transportation and on-site assembly. The use of bolted connection can achieve relative position adjustment between the flat plate 10221 and the T-plate 10222 to ensure installation accuracy, and can be fine-tuned as needed to adapt to different installation conditions or correct errors. During the installation process, an appropriate preload can be applied by tightening the bolts to ensure close contact between the flat plate 10221 and the T-plate 10222, reduce gaps, and improve the overall performance of the system. The flange of the T-plate 10222 can effectively evenly distribute the pressure from the flat plate 10221 to the first guide plates 1021 on both sides, avoiding local stress concentration and enhancing the durability of the structure.

[0074] The modular design and easy maintenance of this setting reduce wear and aging problems in long-term use, extend the service life of the entire damper system, and can flexibly adjust the size and material selection according to different application scenarios to meet specific technical requirements and environmental conditions, with wide applicability.

[0075] Preferably, the bolts are high-strength bolts.

[0076] Preferably, the flat plate 10221 is disposed between the two first guide plates 1021 .

[0077] The flat plate 10221 is arranged between the two first guide plates 1021 so that the flat plate 10221 contacts the base 101, which facilitates adjusting the distance between the upper and lower flanges of the first slider 1022 and applying a pre-tightening force through the through hole in the groove of the base 101, thereby reducing the difficulty of processing the connecting hole in the first slider 1022 and helping to improve the reliability and stability of the structure.

[0078] Specifically, the upper and lower flanges of the first sliding block 1022 are respectively in close contact with the upper and lower surfaces of the horizontal portions of the two first guide plates 1021 .

[0079] The upper and lower flanges of the first slider 1022 are respectively close to the horizontal parts of the two first guide plates 1021, ensuring that the slider can only move in a straight line along a predetermined path, providing a high-precision guiding function, avoiding unnecessary lateral displacement or rotation, and enabling the horizontal part of the guide plate to effectively transmit and disperse the pressure from the slider, thereby enhancing the structural strength of the entire guide assembly, enabling it to withstand greater loads without being easily deformed.

[0080] The close contact between the flange and the horizontal part of this setting enhances the structural stability of the system, provides additional safety protection when facing external impacts, and prevents the slider from falling off the track, especially under extreme conditions.

[0081] Specifically, the first friction portion 10211 , the second friction portion 10212 and the third friction portion 10213 are respectively disposed on the upper and lower sides of the horizontal portion and one side of the vertical portion adjacent to the flat plate 10221 of the first guide plate 1021 .

[0082] Reasonable design of friction pairs can reduce direct impact and wear between components, and extend the service life of the guide plate assembly and other related parts. Although it increases the design complexity, in the long run, due to its good durability and easy maintenance, it actually reduces operating costs and improves economic benefits. The design of multiple friction parts makes the friction force more evenly distributed on the entire contact surface, avoiding local stress concentration, thereby improving the durability and reliability of the system.

[0083] Preferably, the first friction portion 10211 , the second friction portion 10212 and the third friction portion 10213 are all made of stainless steel, and the first friction portion 10211 , the second friction portion 10212 and the third friction portion 10213 are welded to the first guide plate 1021 .

[0084] The excellent properties of stainless steel and the reliability of welded connections reduce wear between components, extend the service life of friction parts and other related parts, and reduce maintenance costs. The stable connection method and good corrosion resistance increase the overall safety performance of the system, especially in extreme situations such as earthquakes, which helps maintain the integrity of the structure and protect the safety of the building.

[0085] Specifically, a fourth friction portion 10223 , a fifth friction portion 10224 and a sixth friction portion 10225 are respectively disposed between the flat plate 10221 and the base 101 , between the flat plate 10221 and the vertical portion of the first guide plate 1021 , and between the flat plate 10221 and the horizontal portion of the first guide plate 1021 .

[0086] The fourth friction portion 10223 is arranged between the base 101, and can provide friction in the vertical direction to prevent the slider from making unnecessary movement in the vertical direction and help disperse the pressure from above. The fifth friction portion 10224 is arranged between the vertical portion and can provide lateral constraints to prevent the slider from making unnecessary lateral sliding in the horizontal plane and increase the lateral stability of the system. The sixth friction portion 10225 is arranged between the horizontal portion and can provide friction in the horizontal direction to ensure that the slider slides along a predetermined path, while absorbing and dispersing external forces in the horizontal direction, transmitting and dispersing the pressure from the flange of the T-plate 10222, and enhancing the structural strength of the entire guide assembly, so that it can withstand a larger load without being easily deformed.

[0087] This setting can maintain the friction coefficient of each part within a reasonable range by selecting appropriate friction materials, which not only ensures smoothness during sliding, but also provides the necessary friction to maintain stability. It can reduce direct impact and wear between components, extend the service life of the guide plate assembly and other related parts, and reduce maintenance costs.

[0088] Specifically, a seventh friction portion 10226 is provided on a side of the flange of the T-shaped plate 10222 adjacent to the horizontal portion of the first guide plate 1021 , and is used to form a top surface friction pair with the first friction portion 10211 .

[0089] The seventh friction portion 10226 and the first friction portion 10211 form a top surface friction pair, which can increase the lateral stability of the system and reduce shaking or tilting during sliding.

[0090] The stable friction fit increases the stability of the system, reduces the shaking or tilting of the slider during sliding, and ensures the consistency and accuracy of the movement. The friction pair can effectively transmit and disperse the pressure from the flange of the T-plate 10222, enhance the structural strength of the entire guide assembly, and enable it to withstand greater loads without being easily deformed.

[0091] The friction pair with reasonable design can reduce direct impact and wear between components, extend the service life of the guide plate assembly and other related parts, and reduce maintenance costs. The top surface friction pair makes the friction force more evenly distributed on the entire contact surface, avoiding local stress concentration, thereby improving the durability and reliability of the system.

[0092] Preferably, the fourth friction part 10223 , the fifth friction part 10224 , the sixth friction part 10225 and the seventh friction part 10226 are non-metallic plates, the fourth friction part 10223 , the fifth friction part 10224 and the sixth friction part 10225 are embedded in the groove on the flat plate 10221 , and the seventh friction part 10226 is embedded in the groove of the T-shaped plate 10222 .

[0093] The fourth friction part 10223 is arranged between the base 101, and can provide friction in the vertical direction, prevent the slider from moving unnecessary in the vertical direction, and help disperse the pressure from above. The fifth friction part 10224 is arranged between the vertical part, and can provide lateral constraints, prevent the slider from sliding unnecessary lateral in the horizontal plane, and increase the lateral stability of the system. The sixth friction part 10225 is arranged between the horizontal part, and can provide friction in the horizontal direction, ensure that the slider slides along the predetermined path, and absorb and disperse the external force in the horizontal direction. The seventh friction part 10226 is arranged to form a top surface friction pair with the first friction part 10211, and can provide friction on the top surface, ensure that the T-plate 10222 slides along the predetermined path, and absorb and reduce the vibration caused by external forces, playing a certain energy dissipation role.

[0094] Non-metallic materials usually have a lower friction coefficient, which can reduce friction resistance, make the slider slide more smoothly, reduce energy loss, and have good vibration reduction performance. They can absorb and reduce the vibration caused by external forces through appropriate friction matching, play a certain role in energy dissipation, and further improve the energy consumption capacity of the system. The design of embedding the friction part in the groove simplifies the installation process and facilitates subsequent inspection and maintenance work, because the functions of each component are clear and easy to disassemble and replace.

[0095] Embedding in the groove not only simplifies the installation process, but also ensures close contact between the friction part and the slider and guide plate, reducing the gap and improving the overall performance of the system. In addition, the groove design can also protect the friction part from the influence of the external environment and extend its service life.

[0096] The low friction coefficient and good wear resistance of the non-metallic material of this setting reduce wear between components, extend the service life of the friction part and other related parts, and reduce maintenance costs. The friction pair makes the friction force more evenly distributed on the entire contact surface, avoiding local stress concentration, thereby improving the durability and reliability of the system.

[0097] Specifically, the metal damper 2 is a rolling deformation energy dissipation metal damper, and the metal damper 2 can be one or more of a U-shaped, a C-shaped and a V-shaped damper.

[0098] The rolling deformation energy dissipation metal damper 2 can dissipate energy by deformation in one direction in the horizontal plane, adapting to the action of earthquake waves or other external forces. These dampers absorb and reduce the vibration caused by external forces by converting mechanical energy into heat energy and dissipating it, playing a certain energy dissipation role, effectively reducing the energy transferred to the building structure, and improving the safety and stability of the building.

[0099] U-type dampers dissipate energy through bending deformation, which is suitable for large deformation and can effectively absorb and dissipate a large amount of energy. C-type dampers dissipate energy through shear deformation, which is suitable for medium deformation and can provide stable energy dissipation performance in a wide frequency range. V-type dampers dissipate energy through tension and compression deformation, which is suitable for small deformation and can provide efficient energy dissipation under high-frequency vibration. The design of U-type, C-type and V-type dampers is compact, which can achieve efficient energy dissipation function in a limited space, and is particularly suitable for application scenarios with strict requirements on installation space.

[0100] This arrangement achieves the conversion from unidirectional energy dissipation to multidirectional energy dissipation by orthogonally coupling two or more unidirectional energy dissipation metal dampers 2 with the metal damping coupling motion bracket, thus solving the problem that the traditional unidirectional energy dissipation damper can only dissipate energy in one direction.

[0101] Specifically, the metal damper 2 is connected to the T-shaped plate 10222 via a connecting piece 4 and a pressing plate 5 .

[0102] The T-plate 10222 is connected to the metal damper 2, which avoids motion interference between the metal damper 2 and the first guide plate 1021 during rolling deformation, and ensures that the metal damper 2 is relatively displaced with the first guide plate 1021 during rolling deformation without affecting its energy consumption performance.

[0103] Preferably, the connecting member 4 is a retaining bolt.

[0104] Specifically, the first guide plate assembly 102 further includes a limit stopper 1023 for limiting the first sliding block 1022 from exceeding a design range.

[0105] The limit stopper 1023 sets the maximum displacement range of the first slider 1022, ensuring that the first slider 1022 does not exceed the predetermined working range, thereby protecting the system from excessive deformation or damage, reducing the risk of the slider coming off the track, especially in extreme cases such as earthquakes, helping to maintain the integrity of the structure and protect the safety of the building. The existence of the limit stopper 1023 ensures the movement accuracy and response consistency of the system, prevents unexpected behavior caused by the first slider 1022 exceeding the working range, and improves the overall performance of the system. When the first slider 1022 approaches the limit position, the limit stopper 1023 can help absorb and disperse the remaining energy, play a certain role in energy dissipation, and further improve the energy consumption capacity of the system.

[0106] The limit stopper 1023 should be made of high-strength, wear-resistant materials, such as stainless steel or special alloys, to ensure its long-term stable working performance. For situations where vibration reduction is required, elastic materials can also be considered as buffer layers to further improve the safety and durability of the system.

[0107] The precise displacement control and reliable limit mechanism of this setting improve the overall reliability of the system and ensure long-term stable operation. By preventing overload damage and reducing unnecessary wear, the service life of the slider, guide plate and other related parts is extended and the maintenance cost is reduced. Reasonable setting of the limit block can achieve efficient limit function in a limited space, which is particularly suitable for application scenarios with strict requirements on installation space.

[0108] Longitudinal deformation: When damping longitudinal deformation, the upper seat plate 301 pushes the third guide plate assembly 302, and the third guide plate assembly 302 moves longitudinally relative to the first guide plate assembly 102, thereby driving the first metal damper 201 to roll and deform on the top surface of the first guide plate assembly 102 and the third guide plate assembly 302, thereby realizing longitudinal deformation energy consumption. Since the second metal damper 202 can slide on the second guide plate assembly 103 and the fourth guide plate assembly 303, longitudinal limit blocks are provided on the second guide plate assembly 103 and the fourth guide plate assembly 303, and the second guide plate assembly 103 and the fourth guide plate assembly 303 have sufficient movable clearance, the second metal damper 202 installed on the second guide plate assembly 103 and the fourth guide plate assembly 303 will not produce plastic deformation.

[0109] Transverse deformation: When damping transverse deformation, the upper seat plate 301 pushes the fourth guide plate assembly 303 to move transversely. The fourth guide plate assembly 303 moves transversely relative to the second guide plate assembly 103, thereby driving the second metal damper 202 to roll and deform on the top surface of the second guide plate assembly 103 and the fourth guide plate assembly 303, thereby realizing transverse deformation energy consumption. Since the first metal damper 201 can move in the first guide plate assembly 102 and the third guide plate assembly 302, the first metal damper 201 installed on the first guide plate assembly 102 and the third guide plate assembly 302 will not produce plastic deformation.

[0110] When deforming at any other angle in the plane: When the device as a whole deforms along a certain angle A in the plane, the first metal damper 201 that bears the longitudinal energy consumption and the second metal damper 202 that bears the transverse energy consumption will both deform along the A direction. However, due to the presence of the embracing guide plate and the I-shaped slider, the deformation of the two dampers will be decomposed into two orthogonal horizontal movements, one is the movement in the energy consumption direction, and the other is the movement in the automatic activity direction. Taking the deformation of the second metal damper 202 that dissipates energy in the transverse direction as an example, the second metal damper 202 will roll and deform in the transverse direction on the top surface of the second guide plate assembly 103 and the fourth guide plate assembly 303 to consume energy, and slide freely in the longitudinal direction in the embracing guide plate in the longitudinal direction. The transverse second guide plate assembly 103 and the fourth guide plate assembly 303 are designed with transverse limit blocks in the longitudinal front and rear, and the second guide plate assembly 103 and the fourth guide plate assembly 303 have sufficient activity clearance, which not only ensures the displacement requirements of the activity design, but also prevents the damper position from exceeding the guide plate length. Two dampers with orthogonal energy dissipation directions can be coupled through a motion coupling bracket to achieve deformation energy dissipation at any angle.
