Description

Technical Field

[0001] This utility model relates to the field of viscous damper technology, and in particular to a viscous damper reinforcement device. Background Technology

[0002] Viscous dampers, as a highly efficient energy dissipation device, have been widely used in seismic reinforcement of building structures, bridge engineering, and other fields. They generate damping force through the shear flow of an internal viscous medium (such as silicone oil), converting structural vibration energy into heat energy for dissipation.

[0003] Existing reinforcement devices mostly use rigid brackets welded to the main structure or connected with high-strength bolts, and dampers are installed by fixing lugs. This can lead to stress concentration problems, as welded joints are prone to stress concentration and weld cracking under long-term cyclic loading. At the same time, the fixed brackets have poor installation adaptability and low operability for later maintenance. Damper replacement requires the complete disassembly of the bracket system, which is a lot of work. Utility Model Content

[0004] The purpose of this utility model is to provide a viscous damper reinforcement device to solve the problems of poor installation adaptability and low operability of later maintenance of the fixed bracket in the prior art, as well as the lack of buffering in the rigid connection, which causes stress concentration and easy damage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a viscous damper reinforcement device, comprising a working component and an installation component, wherein the working component comprises a damper body and mounting rings fixedly connected to both ends of the damper body, and the mounting rings are provided with positioning grooves;

[0006] The installation assembly includes a mounting base and a plug rod mounted on the mounting base. The plug rod has a fixing component inside and a buffer component on the outside.

[0007] Preferably, the positioning grooves are evenly spaced at equal angles on the mounting ring.

[0008] Preferably, the insertion rod includes an installation rod and a mating groove formed on the installation rod, and the mating groove is provided with a mating surface.

[0009] Preferably, the fixing member includes an adjusting rod and a snap-fit ​​structure connected to the adjusting rod, and an adjusting head is fixedly connected to one end of the adjusting rod.

[0010] Preferably, the snap-fit ​​structure includes a snap-fit ​​base and a snap-fit ​​rod rotatably connected to the snap-fit ​​base.

[0011] Preferably, the locking rod moves within the mating groove, and the locking rods are evenly distributed on the locking seat and correspond to the positioning groove.

[0012] Preferably, the buffer includes a buffer groove and a buffer sheet disposed inside the buffer groove, and a buffer spring is fixedly connected to one side of the buffer sheet.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The damper body is mounted on the mounting base using the mounting ring and insert rod. The mounting ring is then secured using the insert rod fastener. One end of the mounting rod is threaded to the cap for easy disassembly. After the mounting rod passes through the mounting ring, the adjusting head is rotated. The threaded connection between the adjusting rod and the snap-fit ​​seat moves the snap-fit ​​seat, causing the snap-fit ​​rod to move within the constraints of the mating groove and engage with the positioning groove, thus completing the installation of the positioning groove. The snap-fit ​​structure allows for the installation of mounting rings with different hole diameters, improving the adaptability of the mounting bracket.

[0015] 2. By setting up a buffer component, the insert rod is installed inside the buffer plate. When the damper body is under force, the insert rod will move to a certain extent inside the buffer groove. At the same time, the buffer spring provides a certain buffering effect to reduce stress concentration, prevent damage at the connection, and improve the service life of the device. In addition, due to the setting of the insert rod and the fixing component, when it is necessary to disassemble the working component, only the working component needs to be disassembled, without disassembling the mounting base, which improves the efficiency of the work.

[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.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a viscous damper reinforcement device, including a working component 10 and an installation component 20. The working component 10 includes a damper body 11 and an installation ring 12 fixedly connected to both ends of the damper body 11. The installation ring 12 is provided with a positioning groove 13. The installation ring 12 is fixedly connected to both ends of the damper body 11, and the positioning groove 13 is evenly set at equal angles on the installation ring 12.

[0023] The mounting assembly 20 includes a mounting base 21 and a plug rod 22 mounted on the mounting base 21. The plug rod 22 has a fixing member 23 inside and a buffer member 24 outside. A mounting plate is fixed on the mounting base 21, and the buffer member 24 is disposed in the mounting plate. The plug rod 22 can be installed and removed on the mounting plate, and the fixing member 23 is installed inside the plug rod 22.

[0024] The insert rod 22 includes an installation rod 221 and a mating groove 222 opened on the installation rod 221. A mating surface 223 is provided on the mating groove 222. The mating groove 222 is opened on the installation rod 221 and has a certain inclination. The mating surface 223 is located inside the mating groove 222 and the inclination is greater than the overall inclination of the mating groove 222.

[0025] The fixing component 23 includes an adjusting rod 231 and a snap-fit ​​structure 232 connected to the adjusting rod 231. One end of the adjusting rod 231 is fixedly connected to an adjusting head 233. The adjusting rod 231 and the adjusting head 233 are fixedly connected. A part of the adjusting head 233 is outside the mounting base 21 for easy use. At the same time, two snap-fit ​​structures 232 are symmetrically arranged on the adjusting rod 231, located on both sides of the mounting ring 12. The part of the adjusting rod 231 that connects to the snap-fit ​​structure 232 is provided with a threaded structure, and the two threads are rotated in opposite directions. When the adjusting rod 231 is rotated, the two snap-fit ​​structures 232 can move in opposite directions to complete the fixing and disassembly of the mounting ring 12.

[0026] The snap-fit ​​structure 232 includes a snap-fit ​​base 2321 and a snap-fit ​​rod 2322 rotatably connected to the snap-fit ​​base 2321. The snap-fit ​​rod 2322 moves within the mating groove 222 and is evenly distributed on the snap-fit ​​base 2321, corresponding to the positioning groove 13. Through the arrangement of the mating groove 222 and the mating surface 223, and the rotatable connection between the snap-fit ​​base 2321 and the snap-fit ​​rod 2322, the snap-fit ​​base 2321 can move the snap-fit ​​rod 2322 stably when it moves, facilitating its snap-fit ​​and fixation with the positioning groove 13.

[0027] The buffer component 24 includes a buffer groove 241 and a buffer plate 242 disposed inside the buffer groove 241. A buffer spring 243 is fixedly connected to one side of the buffer plate 242. The buffer plates 242 are symmetrically arranged inside the buffer groove 241. The insert rod 22 is installed between the two buffer plates 242. At the same time, the two ends of the buffer spring 243 are fixed to the mounting base 21 and the buffer plate 242 respectively, so as to facilitate the buffering of the insert rod 22.

[0028] The working principle and usage process of this utility model are as follows: During installation, the mounting rod 221 passes through the buffer 24 and the mounting ring 12 to install the mounting ring 12 on the mounting base 21. Then, the cover plate is used to fix the insertion rod 22 on the mounting base 21, completing the initial positioning of the mounting ring 12. After that, by rotating the adjusting head 233, it drives the adjusting rod 231 to rotate. Utilizing the threaded connection between the adjusting rod 231 and the snap-fit ​​base 2321, and with the limiting of the snap-fit ​​rod 2322 inside the mating groove 222, the snap-fit ​​rod 2322 moves and engages with the positioning groove 13 to complete the positioning and installation of the working component 10.

[0029] By symmetrically setting the snap-fit ​​structure 232 on both sides of the mounting ring 12, the installation of the working component 10 is more stable. At the same time, the insertion rod 22 can rotate to a certain extent in the buffer 24. Furthermore, due to the setting of the buffer plate 242 and the buffer spring 243, when the working component 10 is subjected to force, the insertion rod 22 can move and buffer to a certain extent inside the buffer groove 241 to prevent damage caused by stress concentration.

[0030] When the device needs to be disassembled and repaired, simply send the fastener 23 to engage and fix the positioning groove 13, and remove the mounting rod 221. The working component 10 can then be removed separately, and the damper body 11 can be inspected and replaced without disassembling the entire mounting base 21. This makes the operation simpler and faster, and improves work efficiency.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
