Description

Technical Field

[0001] This utility model relates to the field of electromechanical equipment technology, and in particular to a vibration damping device for electromechanical equipment. Background Technology

[0002] The core purpose of a vibration damping device for electromechanical equipment is to buffer and attenuate the vibrations and impacts generated during equipment operation, thereby ensuring stable system operation. Its significance is reflected in three aspects: first, protecting equipment by reducing vibration-induced wear, loosening, or fatigue damage to components, thus extending their service life; second, improving safety by preventing severe vibrations from causing equipment displacement, overturning, or failure of precision components; and third, optimizing the environment by reducing noise pollution generated by vibration transmission and minimizing interference with surrounding equipment and building structures. It is particularly suitable for applications involving precision instruments and heavy machinery, and is a key component for ensuring the efficient, safe, and environmentally friendly operation of electromechanical systems.

[0003] A vibration damping device for electromechanical equipment dissipates vibration energy by converting it into heat or other forms through elastic elements and damping materials, or weakens vibration transmission through resonance cancellation. It has a wide range of applications: reducing the impact of vibration on precision components in motors and pumps in industrial production lines; reducing the impact on floors in elevators and central air conditioning units in buildings; reducing operating noise and component wear in vehicle engines and rail transit electromechanical systems in the transportation sector; and ensuring measurement accuracy for precision laboratory instruments through vibration damping. It is a core device for balancing equipment operational stability and environmental friendliness.

[0004] In the prior art, some vibration damping devices for electromechanical equipment generally dampen the motor by placing it on top. This causes the motor to shift under the influence of continuous vibration, resulting in uneven force on the damping device, accelerated aging of elastic elements, and intensified vibration. Severe shift may cause the motor to fall off, the equipment to overturn, and endanger the safety of operators and surrounding facilities. Therefore, a vibration damping device for electromechanical equipment is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vibration damping device for electromechanical equipment, aiming to improve the problem that some existing electromechanical equipment vibration damping devices generally dampen the motor by placing the motor on top, which causes the motor to shift under the influence of continuous vibration, resulting in uneven force on the vibration damping device and accelerated aging of elastic elements.

[0006] To achieve the above objectives, this utility model provides a vibration damping device for electromechanical equipment, including a vibration damping base plate, a vibration damping pad fixedly connected inside the vibration damping base plate, a vibration damping component for vibration damping installed at the bottom of the vibration damping pad, a motor detachably connected to the top of the vibration damping pad, brackets fixedly connected to both sides of the motor, a fixing plate fixedly connected to the top of the vibration damping pad, an mounting plate detachably connected to the top of the vibration damping pad, a limit plate rotatably connected to the top of the mounting plate, a fixing screw threadedly connected to the inner wall of the limit plate, a rotating plate rotatably connected to the top of the fixing plate, and a sliding rod slidably connected to the inner wall of the rotating plate;

[0007] The damping assembly includes a sliding shell, the top of which is fixedly connected to the bottom of the damping base plate, a hollow shell slidably connected to the outer wall of the sliding shell, a plurality of dampers fixedly connected inside the hollow shell, and sliding columns fixedly connected to both sides of the sliding shell.

[0008] The outer wall of the sliding column is slidably connected to the inner wall of the hollow shell, and a limit ring is fixedly connected to the outer wall of the sliding column.

[0009] The top of each damper is fixedly connected to the bottom of the sliding shell, and a rubber pad is fixedly connected to the bottom of the hollow shell.

[0010] The sliding rod is fixedly connected to both sides, the outer wall of the fixing screw is threaded to the inner wall of the mounting plate, and the bottom of the bracket is fixedly connected to the top of the mounting plate.

[0011] Among them, a limiting post is fixedly connected to the adjacent side of the two connecting rods, and the outer wall of the limiting post is detachably connected to the bottom of the limiting plate;

[0012] The inner wall of the rotating plate is fixedly connected to a connecting plate, the inner wall of the connecting plate is slidably connected to a sliding rod, and the outer wall of the sliding rod is fitted with a damping spring.

[0013] One end of the damping spring is fixedly connected to the outside of the sliding rod, and the other end of the damping spring is fixedly connected to the outside of the connecting plate.

[0014] 1. This utility model discloses a vibration damping device for electromechanical equipment. By rotating a rotating plate, the rotation of the rotating plate causes a sliding rod to slide on the inner wall of the rotating plate. When the rotating plate is fully rotated to the top of the fixed plate, the sliding rod will slide on the inner wall of the connecting plate. Then, because a stop plate is sleeved on the outer wall of the sliding rod, the sliding of the sliding rod will be blocked by the connecting plate. At this time, the damping spring is in a compressed state, which facilitates the pulling of the sliding rod and the connecting rod. This causes the connecting rod to drive the limit post to fasten the limit plate installed on the mounting plate, thereby realizing the disassembly and fixation between the mounting plate and the fixed plate. This allows the motor to be installed on the top of the vibration damping pad, thereby preventing the motor from being affected by vibration during continuous operation and causing displacement.

[0015] 2. In this utility model, the residual vibration generated by the motor will be transmitted to the inner wall of the sliding shell through the damping base plate. At this time, the sliding shell will transmit the vibration to the damper. The damper converts the mechanical energy of the structural vibration into non-mechanical energy, so that the vibration energy is eventually consumed in the form of heat dissipation, friction loss, etc., so that the vibration energy of the structure gradually decreases, thereby reducing the vibration amplitude and duration. At this time, the sliding columns on both sides of the sliding shell will slide on the inner wall of the hollow shell to facilitate the damper to absorb the vibration. The rubber pad increases the friction with the ground and further absorbs the vibration. Attached Figure Description

Detailed Implementation

[0022] The embodiment of this application is as follows:

[0023] Reference Figures 1 to 3 The present invention provides an embodiment of a vibration damping device for electromechanical equipment, comprising a vibration damping base plate 1, which provides the installation foundation and support frame for the entire device. A vibration damping pad 2 is fixedly connected inside the vibration damping base plate 1. The vibration damping pad 2 can directly contact the motor 5 and initially absorb the vibration generated by the motor 5. A vibration damping component for vibration damping is installed at the bottom of the vibration damping pad 2. The vibration damping component can further absorb and consume the vibration energy transmitted by the motor 5 to enhance the vibration damping effect. The top of the vibration damping pad 2 is detachably connected to the motor 5. This detachable connection method facilitates the installation, maintenance and replacement of the motor 5.

[0024] Both sides of the motor 5 are fixedly connected to brackets 6. The brackets 6 are used to stably support the motor 5 on the mounting plate 3, ensuring that the motor 5 is firmly connected to the mounting plate 3. The top of the shock-absorbing pad 2 is fixedly connected to a fixing plate 4. The fixing plate 4 provides a rotation fulcrum and installation position for the rotating plate 7. The top of the shock-absorbing pad 2 is detachably connected to the mounting plate 3. The mounting plate 3 is used to support the motor 5 and the brackets 6 and cooperates with the fixing plate 4 to fix the motor 5. The top of the mounting plate 3 is rotatably connected to a limit plate 14. The limit plate 14 can be rotated to adjust its position to cooperate with the limit post 15 for fixation. The inner wall of the limit plate 14 is threaded with a fixing screw 13. The fixing screw 13 can fasten the limit plate 14 to the mounting plate 3 to prevent it from rotating arbitrarily. The top of the fixing plate 4 is rotatably connected to a rotating plate 7. The rotating plate 7 can drive the sliding rod 8 and other components to move by rotating to fix or loosen the limit post 15 on the limit plate 14.

[0025] A sliding rod 8 is slidably connected to the inner wall of the rotating plate 7. The sliding rod 8 can slide on the inner wall of the rotating plate 7 and drive the connecting rod 16 and the limiting post 15 to move. Connecting rods 16 are fixedly connected to both sides of the sliding rod 8. The connecting rods 16 are used to connect the sliding rod 8 and the limiting post 15, so that the movement of the sliding rod 8 can be synchronously transmitted to the limiting post 15. The outer wall of the fixing screw 13 is threadedly connected to the inner wall of the mounting plate 3. The fixing screw 13 is fastened to the limiting plate 14 and the mounting plate 3 through the threaded connection. The bottom of the bracket 6 is fixedly connected to the top of the mounting plate 3, so that the motor 5 is stably installed on the mounting plate 3 through the bracket 6, ensuring the stability of the motor 5 when it is working. The limiting post 15 is fixedly connected to the adjacent side of the two connecting rods 16. The limiting post 15 achieves the limiting and fixing of the limiting plate 14 by contacting the bottom of the limiting plate 14. The outer wall of the limiting post 15 is detachably connected to the bottom of the limiting plate 14. This detachable connection facilitates the disassembly and fixing operation between the mounting plate 3 and the fixing plate 4.

[0026] A connecting plate 10 is fixedly connected to the inner wall of the rotating plate 7. The connecting plate 10 provides an installation and limiting structure for the sliding rod 11 and the damping spring 9. The sliding rod 11 is slidably connected to the inner wall of the connecting plate 10. The sliding rod 11 can slide on the inner wall of the connecting plate 10 and cooperate with the damping spring 9 to achieve elastic extension and contraction. The outer wall of the sliding rod 11 is fitted with a damping spring 9. The damping spring 9 generates elastic force by utilizing its own elastic deformation, which can assist the sliding rod 8 in resetting and enhance the fastening force of the limiting post 15 on the limiting plate 14. One end of the damping spring 9 is fixedly connected to the outside of the sliding rod 8, so that the elastic force of the damping spring 9 can act on the sliding rod 8 to drive it to move. The other end of the damping spring 9 is fixedly connected to the outside of the connecting plate 10, so that the damping spring 9 can obtain a support point when compressed or stretched, thereby generating elastic force.

[0027] Reference Figures 2 to 4 The damping assembly includes a sliding shell 17, which can transmit the vibration from the damping base plate 1 to the damper 19 and slide within the hollow shell 12. The top of the sliding shell 17 is fixedly connected to the bottom of the damping base plate 1, so that the vibration energy of the damping base plate 1 is directly transmitted to the sliding shell 17. The hollow shell 12 is slidably connected to the outer wall of the sliding shell 17. The hollow shell 12 provides installation space for the sliding shell 17 and the damper 19 and restricts the sliding direction of the sliding shell 17. Multiple dampers 19 are fixedly connected inside the hollow shell 12. The multiple dampers 19 work together to improve the absorption and dissipation efficiency of vibration energy. Sliding columns 20 are fixedly connected to both sides of the sliding shell 17. The sliding columns 20 can move synchronously with the sliding shell 17 and slide within the hollow shell 12 to ensure the stability of the sliding shell 17.

[0028] The outer wall of the sliding column 20 is slidably connected to the inner wall of the hollow shell 12, ensuring that the sliding column 20 slides along a predetermined trajectory to prevent the sliding shell 17 from deviating. The outer wall of the sliding column 20 is fixedly connected to a limit ring 18, which can prevent the sliding column 20 from sliding out of the hollow shell 12 and play a limiting protection role. The top of the damper 19 is fixedly connected to the bottom of the sliding shell 17, so that the vibration energy transmitted by the sliding shell 17 can directly act on the damper 19, allowing the damper 19 to work effectively. The bottom of the hollow shell 12 is fixedly connected to a rubber pad 21, which can increase the friction between the device and the ground to prevent the device from sliding, and at the same time, it can deform to further absorb vibration.

[0029] Working principle: When the motor 5 needs to be installed on the top of the shock-absorbing base plate 1, the bracket 6 at the bottom of the motor 5, along with the mounting plate 3, is placed on the surface of the shock-absorbing pad 2 inside the shock-absorbing base plate 1. First, the limiting post 15 is pressed against the bottom of the limiting plate 14. Then, the limiting plate 14 is installed on the top of the mounting plate 3 by the fixing screw 13. Then, the rotating plate 7 is rotated. The rotation of the rotating plate 7 causes the sliding rod 8 to slide on the inner wall of the rotating plate 7. When the rotating plate 7 is completely rotated to the top of the fixing plate 4, the sliding rod 11 will slide on the inner wall of the connecting plate 10. Then, because a stop plate is sleeved on the outer wall of the sliding rod 11, the sliding of the sliding rod 11 will be blocked by the connecting plate 10. At this time, the damping spring 9 is in a compressed state, which facilitates the pulling of the sliding rod 8 and the connecting rod 16. This causes the connecting rod 16 to drive the limiting post 15 to fasten the limiting plate 14, thereby realizing the disassembly and fixation between the mounting plate 3 and the fixing plate 4, so that the motor 5 can be installed on the top of the shock-absorbing pad 2.

[0030] When the motor 5 is working, and it is necessary to dampen the vibration generated by the motor 5, the damping pad 2 will initially dampen the vibration. Then, the remaining vibration generated by the motor 5 will be transmitted to the inner wall of the sliding shell 17 through the damping base plate 1. At this time, the sliding shell 17 will transmit the vibration to the damper 19. The damper 19 converts the mechanical energy of the structural vibration into non-mechanical energy, so that the vibration energy is eventually consumed in the form of heat dissipation, friction loss, etc., so that the vibration energy of the structure gradually decreases, thereby reducing the vibration amplitude and duration. At this time, the sliding columns 20 on both sides of the sliding shell 17 will slide on the inner wall of the hollow shell 12 so that the damper 19 can absorb the vibration. The rubber pad 21 increases the friction with the ground and further absorbs the vibration.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
