Description

Technical Field

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

[0002] A damper is a device that provides resistance to motion and dissipates kinetic energy. The working principle of a damper is to induce various deformations in the structure through the damping mechanism, such as friction, bending, torsion, and shearing, to absorb the energy generated by vibrations input into the structure. This reduces the seismic response of the main structure, effectively preventing structural damage or collapse. These deformations dissipate energy, significantly reducing the energy input to the structure and thus rapidly decreasing its dynamic response.

[0003] Traditional damping devices typically have fixed damping characteristics and cannot be flexibly adjusted according to actual needs. Therefore, when it is necessary to change the damping characteristics, it may be necessary to replace the entire damper or perform complex adjustments, which increases maintenance costs and operational complexity. Traditional damping devices usually require cumbersome steps to install, which may involve the assembly of multiple fasteners and connecting parts, increasing installation time and costs. Utility Model Content

[0004] The purpose of this invention is to address the problems in the prior art where the damping value of the damper cannot be adjusted and the installation of the damper is inconvenient, and to propose an adjustable damper device.

[0005] The technical solution of this utility model: an adjustable damper device, comprising:

[0006] A fixed frame, on which a mounting plate is snapped, and telescopic rods are provided on both sides of the mounting plate;

[0007] A positioning component, which is mounted on a fixed frame, is used to quickly install and remove the mounting plate in the working state;

[0008] The damper body is mounted on a mounting plate, and a connecting plate is provided on the top of the damper body;

[0009] A lifting assembly is mounted on the telescopic rod and, in operation, is used to adjust the height of the connecting plate and the characteristics of the damper body.

[0010] Furthermore, a piston rod is slidably disposed on the damper body, one end of the piston rod is connected to a connecting plate, and a piston is disposed at the other end of the piston rod. The piston is slidably disposed within the damper body, and a spring is disposed within the damper body, the spring being connected to the piston.

[0011] Furthermore, the lifting assembly includes a mounting frame, a drive motor, a first gear, and a first rack; the mounting frame is mounted on the telescopic rod; the drive motor is mounted on a set of mounting frames; the first gear is rotatably mounted within the mounting frame and connected to the output shaft of the drive motor; the first rack is slidably mounted on the mounting frame and connected to the connecting plate, and the first rack meshes with the first gear.

[0012] Furthermore, the mounting frame has a cavity for accommodating the first gear and the first rack.

[0013] Furthermore, the positioning assembly includes a connecting column, a second gear, a second rack, and a positioning block; the positioning block is disposed on both sides of the bottom of the mounting plate and is engaged with the fixing frame; the connecting column is rotatably disposed on the fixing frame, and a rotating disk is provided at the protruding end of the connecting column; the second gear is disposed on the outer peripheral wall of the connecting column and is rotatably disposed within the fixing frame; the second rack is slidably disposed on the fixing frame and inserted into the positioning block, and the second rack meshes with the second gear.

[0014] Furthermore, a positioning post is inserted into the rotating disk, and the positioning post is fitted into the fixing frame.

[0015] Furthermore, both the rotating disk and the fixed frame are provided with circular holes that mate with the positioning pins.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] (1) By setting up lifting components, the height of the connecting plate and the damping value of the damper body can be adjusted when needed. For example, in mechanical equipment, different operating speeds and load conditions may require different damping effects. The damper body with adjustable damping value can be adjusted according to actual needs to ensure that the equipment can maintain a stable operating state under different working conditions. In the seismic design of high-rise buildings or bridges, by precisely adjusting the damping value of the damper body, seismic energy can be absorbed and dissipated more effectively, thereby improving the seismic performance of the structure.

[0018] (2) By setting up positioning components, the damper body can be quickly installed in the required position, which not only simplifies the installation process of the damper body, but also facilitates subsequent maintenance and replacement. When the damper body needs to be repaired or replaced, it can be easily disassembled and reinstalled, reducing maintenance difficulty and cost. Attached Figure Description

Detailed Implementation

[0024] Example 1

[0025] like Figures 1-4 As shown, this utility model proposes an adjustable damper device, including a fixed frame 1, a positioning component, a damper body 3, and a lifting component. A mounting plate 2 is snapped onto the fixed frame 1, and telescopic rods 4 are provided on both sides of the mounting plate 2. The positioning component is mounted on the fixed frame 1 and, in operation, is used for quick installation and removal of the mounting plate 2. The damper body 3 is mounted on the mounting plate 2, and a connecting plate 6 is provided on the top of the damper body 3. The lifting component is mounted on the telescopic rods 4 and, in operation, is used to adjust the height of the connecting plate 6 and the characteristics of the damper body 3.

[0026] like Figure 2 As shown, a piston rod 7 is slidably disposed on the damper body 3. One end of the piston rod 7 is connected to the connecting plate 6, and a piston 8 is disposed at the other end of the piston rod 7. The piston 8 is slidably disposed inside the damper body 3. A spring 9 is disposed inside the damper body 3, and the spring 9 is connected to the piston 8.

[0027] like Figure 3 As shown, the lifting assembly includes a mounting frame 5, a drive motor 10, a first gear 11, and a first rack 12. The mounting frame 5 is mounted on the telescopic rod 4. The drive motor 10 is mounted on a set of mounting frames 5. The first gear 11 is rotatably mounted inside the mounting frame 5 and connected to the output shaft of the drive motor 10. The first rack 12 is slidably mounted on the mounting frame 5 and connected to the connecting plate 6. The first rack 12 meshes with the first gear 11, and a limiting block is provided at the bottom of the first rack 12 to limit its movement. The mounting frame 5 has a cavity for accommodating the first gear 11 and the first rack 12. In the seismic design of high-rise buildings or bridges, by precisely adjusting the damping value of the damper body 3, seismic energy can be absorbed and dissipated more effectively, thereby improving the seismic performance of the structure.

[0028] Example 2

[0029] The present invention proposes an adjustable damper device, and compared with Embodiment 1, this embodiment describes the structure of the positioning component in detail.

[0030] like Figure 4 As shown, the positioning assembly includes a connecting column 15, a second gear 16, a second rack 17, and a positioning block 19. The positioning block 19 is disposed on both sides of the bottom of the mounting plate 2 and is engaged with the fixing frame 1. The connecting column 15 is rotatably disposed on the fixing frame 1, and a rotating disk 13 is provided at the protruding end of the connecting column 15. A positioning column 14 is inserted into the rotating disk 13 and is fitted into the fixing frame 1. Both the rotating disk 13 and the fixing frame 1 have circular holes that cooperate with the positioning column 14. The second gear 16 is disposed on the outer peripheral wall of the connecting column 15 and is rotatably disposed within the fixing frame 1. The second rack 17 is slidably disposed on the fixing frame 1 and inserted into the positioning block 19. Two sets of the second rack 17 are provided. The second rack 17 meshes with the second gear 16. A limiting plate 18 is provided at the end of the second rack 17 away from the positioning block 19 to limit its movement. The use of the positioning assembly can significantly reduce the installation time of the damper body 3, reduce installation costs, and improve installation efficiency.

[0031] In summary, when using this utility model, firstly, the positioning block 19 is inserted into the fixing frame 1. Then, the rotating disk 13 is manually rotated to drive the connecting column 15 and the second gear 16 to rotate, so that the two sets of second racks 17 move closer to the two sets of positioning blocks 19 in the fixing frame 1 and are inserted into the positioning blocks 19 to fix the mounting plate 2. When it is necessary to adjust the damping value of the damper body 3, the drive motor 10 is turned on by controlling the external switch, thereby driving the first gear 11 to rotate, which in turn drives the first rack 12, the connecting plate 6 and the telescopic end of the damper body 3 to move upward. After moving to the appropriate position, the drive motor 10 is stopped, so that the damper body 3 can be used for different situations, ensuring that the damper body 3 can play the maximum vibration reduction effect at critical moments, thereby reducing the risk of accidents.
