Description

Technical Field

[0001] This utility model relates to the field of structural vibration reduction and control technology, specifically a modular friction damper that is easy to maintain and replace. Background Technology

[0002] The core principle of a friction damper is to generate friction through the relative sliding between solid contact surfaces, which converts the kinetic energy of structural vibration into heat energy and dissipates it, thereby achieving the purpose of vibration reduction. The key to its technical solution lies in how to achieve stable, reliable and predictable friction behavior.

[0003] Existing friction dampers are integral units, making maintenance difficult. After the friction plates wear down, the current maintenance method is as follows: 1. Requires complete disassembly; 2. Remove the friction pads and replace them with new ones, then tighten them according to the set preload.

[0004] The overall maintenance cost is high and time-consuming, especially in high-altitude or confined spaces where operation is difficult. To address these issues, we propose a modular friction damper that is easy to maintain and replace. Utility Model Content

[0005] The purpose of this invention is to provide a modular friction damper that is easy to maintain and replace, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular friction damper that is easy to maintain and replace, comprising a base, a back plate assembly fixedly connected to one end of the top of the base, the four corners of the back plate assembly being respectively connected to one end of a double-ended stud through a threaded structure, a sleeve being provided on the double-ended stud, one end of the sleeve abutting against the back plate assembly, the other end of the sleeve abutting against a panel assembly, a sliding assembly being provided between the back plate assembly and the panel assembly, and a friction module being provided inside the sliding assembly.

[0007] Preferably, the end of the double-ended stud is connected to a nut via a threaded structure.

[0008] Preferably, the back panel assembly and the front panel assembly have the same structure and are arranged opposite to each other.

[0009] Preferably, the back panel assembly includes a positioning frame, a limiting block, and a vertical plate. The positioning frame is fixedly connected to the middle of one end face of the vertical plate, and the limiting blocks are fixedly connected to the inner walls of the four corners of the positioning frame.

[0010] Preferably, the sliding assembly includes a sliding frame and adjusting bolts. Multiple adjusting bolts are connected to both sides of the sliding frame via a threaded structure. A friction module is sleeved inside the sliding frame. The sliding frame is located between the vertical plates of the back plate assembly and the front panel assembly.

[0011] Preferably, the friction module includes a nut, a friction clamp, a friction material, a sliding plate, a disc spring, a bolt, a groove, a round hole, and an elongated hole. The sliding plate is disposed in the sliding frame, and both sides of the sliding plate abut against one end of the friction material, while the other end of the friction material abuts against the friction clamp. Two disc springs abut against one end of the friction clamp on one side.

[0012] Preferably, the friction plates have recessed grooves on opposite end faces, and friction materials are embedded in the grooves. The sliding plate has elongated holes on both sides of its middle section, and the friction plates and friction materials have round holes on both sides of their middle sections. One end of the bolt passes through a disc spring, a friction plate, a friction material, a sliding plate, another friction material, and another friction plate in sequence, and is connected to a nut via a threaded structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The overall detachable design of this utility model reduces the time and cost of replacing the entire friction damper. When maintenance or replacement of the friction module is required, it is not necessary to disassemble the entire damper from the structure. Only specific modules need to be operated, which greatly improves maintenance efficiency and reduces the difficulty of operation at high altitudes or in narrow spaces. 2. The modular design allows each component to be replaced and upgraded independently. When a component wears out or needs a technical update, it can be replaced individually without replacing the entire damper. This not only saves costs but also extends the overall service life of the damper. 3. By setting the sliding components and adjusting bolts, the preload of the friction module can be precisely adjusted to ensure the stability and reliability of the friction behavior. This adjustability also enables the damper to adapt to the vibration reduction requirements under different working conditions. 4. The disc spring design in the friction module compensates for slight wear of the friction plates in the thickness direction, ensuring that the output force of the friction module remains unchanged. 5. The overall structure is compact, and the connections between the components are firm and reliable, reducing the difficulty of maintenance. Especially in special environments, this compact and reliable design can effectively reduce the risk of failure caused by loose components or connection failure, ensuring that the damper can still play a stable role in shock absorption under complex working conditions.

Detailed Implementation

[0016] 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.

[0017] Example 1 Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides a modular friction damper that is easy to maintain and replace. It includes a base 12, a back plate assembly 2 fixedly connected to one end of the top of the base 12, and a double-ended stud 4 connected to one end of the four corners of the back plate assembly 2 by a threaded structure. A sleeve 3 is provided on the double-ended stud 4. One end of the sleeve 3 abuts against the back plate assembly 2, and the other end of the sleeve 3 abuts against the panel assembly 8. A sliding assembly 9 is provided between the back plate assembly 2 and the panel assembly 8. A friction module 1 is provided inside the sliding assembly 9.

[0018] Example 2 Reference Figure 1-4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the end of the double-headed stud 4 is connected to a nut 5 through a threaded structure. The back plate assembly 2, the panel assembly 8, and the friction module 1 are installed by pre-tightening the nut 5.

[0019] Specifically, the back panel assembly 2 and the front panel assembly 8 have the same structure and are positioned opposite each other.

[0020] Specifically, the backplate assembly 2 includes a positioning frame 6, a limiting block 7, and a vertical plate 13. The positioning frame 6 is fixedly connected to the middle of one end face of the vertical plate 13. The limiting blocks 7 are fixedly connected to the inner walls of the four corners of the positioning frame 6. The vertical plate 13 of the backplate assembly 2 is fixedly connected to the base 12. The vertical plate 13 of the panel assembly 8 is movably set. The positioning frame 6 and the limiting block 7 of the backplate assembly 2 cooperate to position the friction clamp 102 on one side of the friction module 1. The positioning frame 6 and the limiting block 7 of the panel assembly 8 cooperate to position the friction clamp 102 on the other side of the friction module 1.

[0021] Specifically, the sliding assembly 9 includes a sliding frame 10 and adjusting bolts 11. Multiple adjusting bolts 11 are connected to both sides of the sliding frame 10 by a threaded structure. The friction module 1 is fitted inside the sliding frame 10. The sliding frame 10 is located between the back plate assembly 2 and the vertical plate 13 of the panel assembly 8. By installing the adjusting bolts 11, the displacement of the sliding plate 104 of the friction module 1 is realized.

[0022] Specifically, the friction module 1 includes a nut 101, a friction clamp 102, a friction material 103, a sliding plate 104, a disc spring 105, a bolt 106, a groove 107, a round hole 108, and an elongated hole 109. The sliding plate 104 is located inside the sliding frame 10. Both sides of the sliding plate 104 abut against one end of the friction material 103, and the other end of the friction material 103 abuts against the friction clamp 102. Two disc springs 105 abut against the end of one side of the friction clamp 102.

[0023] Specifically, the friction plates 102 have recessed grooves 107 on opposite end faces, and friction materials 103 are embedded in the grooves 107. The sliding plate 104 has elongated holes 109 on both sides of its middle section. The friction plates 102 and friction materials 103 have round holes 108 on both sides of their middle sections. One end of the bolt 106 passes through the disc spring 105, one friction plate 102, one friction material 103, the sliding plate 104, another friction material 103, and another friction plate 102 in sequence, and is connected to a nut 101 by a threaded structure.

[0024] Friction material 103 is installed between the two friction plates 102 and the sliding plate 104. The sliding plate 104 has an elongated hole 109. The relative displacement between the sliding plate 104 and the friction plates 102 causes friction energy dissipation. The output of the friction module 1 is controlled by applying a specific preload to the nut 101 and the bolt 106. The function of the disc spring 105 is to compensate for the size in the thickness direction after the friction plate is slightly worn, so that the output of the friction module remains unchanged.

[0025] The working principle and process are as follows: During maintenance and replacement, the friction module 1 can be replaced by removing the nut 5 on one side of the panel assembly 8. The relative displacement that has occurred can be compensated by adjusting the adjusting bolt 11. First, remove the nut 5 on one side of the panel assembly 8. At this time, the connection between the panel assembly 8 and the double-ended stud 4 is released. Since the sliding assembly 9 and the friction module 1 are located between the back plate assembly 2 and the panel assembly 8, and the friction module 1 is fitted inside the sliding frame 10 of the sliding assembly 9, the friction module 1 can be directly removed from the sliding frame 10 for replacement. After replacing the new friction module 1, reinstall the nut 5 to fix the back plate assembly 2 and the panel assembly 8. At the same time, by adjusting the adjusting bolt 11 on the sliding assembly 9, the position of the sliding plate 104 can be adjusted according to actual needs to compensate for the relative displacement that has occurred, ensuring that the friction module 1 can work normally and achieve stable and reliable friction behavior, thereby achieving a good shock absorption effect.

[0026] 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.
