Description

Technical Field

[0001] This invention relates to the field of anti-vibration base technology, and more specifically, to an active anti-vibration base with an air spring and a controller. Background Technology

[0002] Active seismic isolation bases are advanced vibration damping devices that employ active control technology. Through built-in sensors, they monitor vibration in real time and immediately activate a precise adjustment system to counteract or reduce the impact of vibrations. These bases not only effectively cope with vibrations caused by natural factors such as earthquakes and wind, but also ensure the stable operation and accuracy of equipment in fields such as precision instruments and high-end manufacturing. Their intelligent and adaptive features make active seismic isolation bases an indispensable and crucial device for improving building safety and protecting precision equipment.

[0003] For example, patent CN115125985A discloses a cast-in-place building foundation with shock absorption effect, including a mounting base, a support plate inside the mounting base, a first sleeve rotatably connected inside the support plate, two rotating blocks on the first sleeve, each rotating block having a connecting rod assembly, a lifting rod at the end of the connecting rod assembly away from the rotating block, the top of the lifting rod connected to the cast-in-place base, a first elastic element on the bottom side of the cast-in-place base, the first elastic element being sleeved on the lifting rod, the end of the first elastic element away from the cast-in-place base connected to the mounting plate, a bolt between the mounting base and the mounting plate, a positioning assembly inside the mounting base to restrict the rotation of the bolt, the positioning assembly being connected to the first sleeve through a transmission assembly; this facilitates improved shock absorption effect on the building foundation, improves the stability of the building structure, and can effectively improve the construction progress. Although the device has a shock absorption effect, it has limitations. It only reduces vibration in the vertical direction of the base. When the device is impacted in the horizontal direction and shakes, the vibration amplitude is large, which makes it difficult to promote and implement, reduces work efficiency, and fails to meet the needs of the staff.

[0004] Therefore, in order to solve such problems, we propose an active shock-absorbing base with an air spring and controller. Summary of the Invention

When the device is impacted in the horizontal direction and shakes, the vibration amplitude is large, which is not convenient for widespread implementation and reduces work efficiency.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention proposes an active shock-absorbing base with air springs and a controller. It utilizes the interaction of a first spring and a first damping rod to vertically dampen the placement plate, and the interaction of a sliding rod, a limiting block, and a cylinder to horizontally dampen the placement plate.

Six sets of air springs are provided to dampen various positions at the bottom of the device, preventing the device from shaking when impacted horizontally. The structure is simple and easy to operate. Attached Figure Description

[0037] Specifically, the interaction between the slide bar 54, the limiting block 55, the return spring 563 and the cylinder 56 provides lateral shock absorption for the device on top of the placement plate 35.

[0038] There is a gap between block 34 and the inner wall of square groove 11, and the maximum horizontal offset length of connecting rod 32 is equal to the distance between block 34 and the inner wall of square groove 11.

[0039] Specifically, the spacing between block 34 and slot 11 is used to leave buffer space.

[0040] A circular hole 321 is provided in the middle of the connecting rod 32, and the fixing rod 31 is located in the circular hole 321.

[0041] Specifically, the round hole 321 is used to install and fix the fixing rod 31.

[0043] Specifically, the through hole 561 and the hollow cavity 562 are used to install the slide rod 54 and the limiting block 55.

[0044] Furthermore, in order to enhance the stability of the device and improve the vibration damping effect, such as Figure 10 As shown, the following preferred technical solutions are provided.

[0045] Block 34 is located inside the square groove 11, and the length and width of the square groove 11 are greater than the length and width of the block 34.

[0046] The slide rod 54 is located inside the through hole 561, and the upper T-shaped piece 53 and the cylinder 56 are slidably connected to the through hole 561 through the slide rod 54.

[0047] The diameter of the limiting block 55 is the same as the diameter of the hollow cavity 562, and the outer wall of the limiting block 55 abuts against the inner wall surface of the hollow cavity 562.

[0048] The bottom of the hollow cavity 562 is fixedly connected to the bottom of the return spring 563, and the top of the return spring 563 is fixedly connected to the bottom of the limit block 55.

[0049] Working principle: First, the device to be installed is placed on top of the placement plate 35. When the device is impacted, causing longitudinal shaking, the placement plate 35 drives the block 34 to move up and down within the square groove 11. This causes the block 34 to press down on the fixing block 3, fixing rod 31, and connecting rod 32. The block 34 then presses down on the first spring 23 and the first damping rod 22. Consequently, the connecting rod 32 presses down on the upper support block 41 and the second spring 43. The first spring 23 and the second spring 43 rebound upwards to reset due to their elasticity. The first damping rod 22 and the second damping rod 42 cause the block 34 to perform buffering reset, preventing shaking. The large amplitude of the movement causes the device to shake more violently. When the block 34 is reset, the device is impacted and shakes in the longitudinal and lateral directions. The top plate 15 is offset. The top plate 15 drives the upper U-shaped part 51, the upper fixing bolt 52, the upper T-shaped part 53, the slide rod 54 and the limiting block 55 to move to both ends. The slide rod 54 and the limiting block 55 move inside the cylinder 56. The elastic effect of the reset spring 563 is used to dampen the top plate 15. At the same time, the second spring 43 and the second damping rod 42 below the connecting rod 32 buffer and reset the left and right shaking of the top plate 15, realizing comprehensive shock absorption. The structure is simple and easy to operate.
