Description

Technical Field

[0001] This application relates to the field of structural vibration reduction technology, specifically to a graded energy-dissipating disc spring self-resetting damper. Background Technology

[0002] Once installed, the energy dissipation capacity of existing energy-dissipating dampers is often fixed, which may result in insufficient energy dissipation capacity for different earthquake intensities or ineffective energy dissipation for smaller earthquakes.

[0003] Reset materials should typically possess high load-bearing capacity and strong elastic deformation capacity. Shape memory alloys are a good choice, but their high cost makes them difficult to popularize. Prestressed tendons, while cheaper, are difficult to anchor, have poor durability, and can lead to prestress loss. Disc springs, on the other hand, are a self-restoring material with stable compressive properties and good economic efficiency. Their load-bearing capacity and deformation capacity can be flexibly set through different combinations, solving the problems of high cost, difficult anchoring, and prestress damage associated with reset materials.

[0004] According to existing seismic design codes, structures are allowed a certain degree of plastic deformation under strong earthquakes to prevent collapse. However, the residual deformation generated by the structure poses significant challenges to post-earthquake maintenance and renovation, resulting in extremely high maintenance costs. Therefore, reducing residual deformation after an earthquake is a crucial issue that needs to be addressed. Self-resetting energy-dissipating dampers have been widely used in engineering due to their excellent self-recovery and stable energy dissipation capabilities.

[0005] Therefore, to meet practical needs, a graded energy-dissipating disc spring self-resetting damper is provided. Summary of the Invention

In the case of small to medium earthquakes, the damper can achieve vibration reduction by relying on only the first-level energy dissipation group; in the case of large earthquakes, the second-level energy dissipation group works together with the first-level energy dissipation group to dissipate energy.

[0123] Based on the accompanying drawings in the instruction manual Figure 1 The specific operation of the technical solution in the embodiments of this application will be described below:

[0124] In use, the disc spring self-resetting damper is connected between two external connection devices, specifically the top and bottom ends of the guide rod 3 are connected between the two external connection devices.

[0125] First operating condition:

[0126] The guide rod 3 is subjected to a force from the top to the bottom. At this time, the first push block 30 is in contact with the second push plate 8b after assembly. However, due to the inner wall of the second accommodating cavity 22 in the inner sleeve structure, the first push block 30 is not subjected to force. When the disc spring self-resetting damper enters the working state, the first push block 30 will immediately compress the second push plate 8b, thereby compressing the No. 1 primary reset disc spring group 4a.

[0127] At the same time, the first mounting base block 31 will also move downward synchronously with the first push block 30, and the first metal energy dissipation plate 310 will deform due to the limitation of the second recessed structure 240.

[0128] Furthermore, the first mounting base block 31 will press the third push plate 8c on the top inner wall of the fifth receiving cavity 25, thereby compressing the No. 2 primary reset disc spring group 4b.

[0129] At this time, the No. 1 primary reset disc spring group 4a and the No. 2 primary reset disc spring group 4b are mainly used to provide the reset function, while the internal energy of the plastic deformation of the first metal energy dissipation plate 310 is used to realize the shock absorption function.

[0130] When a moderate to large earthquake occurs, the ground motion input energy is relatively large. The guide rod 3 continues to move downward until the second push block 32 contacts the second sliding push block 6 and pushes the second sliding push block 6 to move downward. At this time, the third metal energy dissipation plate 60 will deform due to the limitation of the third recessed structure 260. The shock absorption function is achieved through the internal energy of the plastic deformation of the first metal energy dissipation plate 310 and the third metal energy dissipation plate 60.

[0131] The movement of the second sliding pusher 6 and the fourth pusher 8d is synchronized. The energy input by the seismic vibration will be converted into the deformation internal energy of the third metal energy dissipation plate 60 and the compressive potential energy of the second secondary reset disc spring group 7b at the same time.

[0132] Under this condition, the No. 1 primary reset disc spring group 4a and the No. 2 primary reset disc spring group 4b are mainly used to perform the reset function, while the first metal energy-consuming plate 310 serves as the primary energy-consuming working part.

[0133] The No. 1 secondary reset disc spring group 7a and the No. 2 secondary reset disc spring group 7b are also mainly used to perform the reset function, and the first metal energy dissipation plate 310 and the third metal energy dissipation plate 60 serve as secondary energy dissipation working parts.

[0134] The final shock absorption effect is achieved through the above two-stage energy dissipation.

[0135] Second working condition:

[0136] The guide rod 3 is subjected to a force from the bottom to the top. At this time, the second push block 32 moves upward and gradually enters the fifth receiving cavity 25, and contacts the third push plate 8c located on the bottom inner wall of the fifth receiving cavity 25, thereby pressing the No. 2 first-stage reset disc spring group 4b.

[0137] At the same time, the first mounting base block 31 will also move upward synchronously with the first push block 30, and the first metal energy dissipation plate 310 will deform due to the limitation of the second recessed structure 240.

[0138] Furthermore, the first mounting base block 31 will press the second push plate 8b on the bottom inner wall of the third receiving cavity 23, thereby compressing the first primary reset disc spring assembly 4a.

[0139] At this time, the reset function is achieved by the No. 2 primary reset disc spring group 4b and the No. 1 primary reset disc spring group 4a, while the internal energy of the plastic deformation of the first metal energy dissipation plate 310 is used to achieve the shock absorption function.

[0140] When a moderate to large earthquake occurs, the ground motion input energy is relatively large. The first push block 30 contacts the first sliding push block 5 and pushes the first sliding push block 5 to move upward. At this time, the second metal energy-dissipating plate 50 will deform due to the limitation of the first recessed structure 220. The shock absorption function is achieved through the internal energy of the plastic deformation of the first metal energy-dissipating plate 310 and the second metal energy-dissipating plate 50.

[0141] The first push block 30 presses the first push piece 8a on the bottom inner wall of the first receiving cavity 21, thereby pressing the No. 1 secondary reset disc spring group 7a, causing the No. 1 secondary reset disc spring group 7a to deform.

[0142] Under this condition, the No. 1 primary reset disc spring group 4a and the No. 2 primary reset disc spring group 4b are mainly used for the reset function, and the first metal energy-consuming plate 310 serves as the primary energy-consuming working part.

[0143] The No. 1 secondary reset disc spring group 7a is mainly used for the reset function, and the second metal energy-consuming plate 50 serves as the secondary energy-consuming working part.

[0144] The final shock absorption effect is achieved through the above two-stage energy dissipation.

[0145] It should be noted that in the detailed description of the first and second working conditions, downward movement specifically refers to movement from the top end of the guide rod 3 to the bottom end, while upward movement specifically refers to movement from the bottom end of the guide rod 3 to the top end. That is, the directions of "upward" and "downward" are based on the top and bottom ends of the guide rod 3, and the description method is adopted for the convenience of description.

[0146] Furthermore, the shape, size, opening size, and material strength of each component in the technical solution of this application embodiment are all adapted to the first and second working conditions described above, so as to achieve the purpose of graded energy consumption.

[0147] In summary, the technical solutions of this application have the following technical advantages:

[0148] The technical solution of this application uses a preloaded disc spring assembly as the damper reset element, which saves the cost of reset materials and makes assembly and installation more convenient. The performance of the reset disc spring can be changed by altering the combination of disc springs to meet different engineering needs.

[0149] Except for the energy-consuming metal sheet, all components of the technical solution in this application embodiment can be reused. After an earthquake, only a new energy-consuming sheet needs to be replaced for reuse. The structure is simple, the force transmission mechanism is clear, and the components of the device are easy to modularly process.

[0150] The technical solution of this application embodiment can perform energy dissipation in stages for different earthquake intensities. In the case of small to medium earthquakes, the damper can achieve vibration reduction by relying on only the first-level energy dissipation group; in the case of large earthquakes, the second-level energy dissipation group works together with the first-level energy dissipation group to dissipate energy.

[0151] In the description of this application, it should be noted that the terms "upper," "lower," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise expressly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0152] It should be noted that in this application, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0153] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed herein.
