Description

Technical Field

[0001] The present invention relates to the technical field of vibration suppression devices, and particularly to a composite multi-band vibration suppression device. Background Art

[0002] In modern industries and high-tech fields, vibration suppression technology has important application values, especially in the fields of aerospace, transportation, precision instruments, and construction engineering. Vibration has a significant impact on the normal operation, precision requirements, and safety of equipment. Especially in the case of high-speed movement or long-term operation, vibration has a remarkable influence on the stability and lifespan of the system. Therefore, developing efficient, stable, and multi-band applicable vibration suppression devices is an important direction for the development of vibration control technology.

[0003] Most traditional vibration suppression devices can only effectively suppress vibrations in specific frequency bands. For vibration sources with a broad spectrum, traditional devices often cannot provide full-band suppression effects, resulting in the inability to effectively eliminate vibrations at certain frequencies. Especially under different working conditions, they cannot be adjusted in real time according to vibration intensity or environmental changes. This makes the device unable to achieve the best suppression effect in the face of complex vibration environments, leading to a reduction in suppression efficiency.

[0004] During long-term use, traditional dampers often generate high temperatures due to continuous vibration absorption, especially under high load or high-speed operation. Excessive temperature not only reduces the performance of damping materials but may also cause equipment failures or accelerate aging, thus affecting the reliability and service life of the equipment.

[0036] Working principle: First, the support platform 1 is vibrated to drive the first limiting plate 5 to slide inside the protection plate 2, causing the support platform 1 to drive the second connecting block 12 to move. The second connecting block 12 rotates on the first connecting rod 11 and drives the first connecting rod 11 to move. The first connecting rod 11 drives the first connecting block 10 to move. The first connecting block 10 slides on the first limiting rods 8 and 32, and the movement of the sliding plate 7 squeezes the first spring 9.

The first connecting rod 11 pushes the second connecting block 12 to move. The second connecting block 12 drives the support platform 1 to slide on the protection plate 2, and the movement of the first limiting plate 5 is limited by the baffle 4. The output end of the electric push rod 37 drives the rotating plate 13 to move. The rotating plate 13 slides inside the limiting groove 16. The rotating plate 13 drives the adjusting rod 18 to move.

The movement of the support platform 1 drives the fourth connecting block 26 to move. The fourth connecting block 26 drives the third connecting rod 25 to move. The third connecting rod 25 rotates on the third connecting block 24 and squeezes the damper 23 through the third connecting block 24. The damper 23 absorbs the energy of the vibration. The movement of the support platform 1 drives the first limiting plate 5 to move. The first limiting plate 5 drives the sliding rod 22 to move. The sliding rod 22 pushes the rack 30 to move. When the movement of the rack 30 drives the third gear 38 to move and the third gear 38 drives the ratchet 39 to rotate, the ratchet 39 meshes with the pawl 35 and drives the rotating block 33 to move. The rotating block 33 drives the second gear 31 to rotate. The second gear 31 drives the first gear 28 to rotate. The vibration of the first gear 28 drives the fan 29 to rotate. The air flows inside the cooling box 20 and contacts the cooling plate 27. Further, the cooling plate 27 cools the damper 23. The sliding rod 22 pulls the rack 30 to move, causing the third gear 38 to rotate and driving the ratchet 39 to rotate to squeeze the pawl 35. The pawl 35 squeezes the second spring 34.
