Detailed Implementation

[0017] The following are specific implementation cases and appendices. Figures 1-5 The present invention will be further described, but the present invention is not limited to these embodiments.

[0018] A type of combined vibration isolation bearing, such as Figures 1-5As shown, the assembly includes: a lower partition 10, a moving groove 39, a first vibration isolation component, a support component, a second vibration isolation component, a top plate 18, a third damping spring 19, an upper partition 20, and a sensor group; the surface of the lower partition 10 is provided with a rubber layer; the moving groove 39 is disposed on the lower partition 10; the first vibration isolation component includes a first rubber plate 12, a first damping spring 13, and a first electromagnetic damper 14, the bottom of the first rubber plate 12 is provided with a moving block, the moving block is embedded in the moving groove 39, and one end of the first damping spring 13 and the first electromagnetic damper 14 are respectively disposed and connected to the top surface of the first rubber plate 12; the support component includes a support assembly and mounting rods 11, the support component is disposed on the first rubber plate 12; the second vibration isolation component includes a second rubber plate 15, a second damping spring 16, and a second electromagnetic damper 17, the second rubber plate 15 passes through four mounting rods 11 respectively, the bottom surface of the second rubber plate 15 is connected to the other end of the first damping spring 13, and the working end of the first electromagnetic damper 14 is... The second damping spring 16 is attached to the bottom surface of the second rubber plate 15, and one end of the second damping spring 16 and the second electromagnetic damper 17 are respectively set on the top surface of the second rubber plate 15; the top plate 18 passes through four mounting rods 11, the bottom surface of the top plate 18 is connected to the other end of the second damping spring 16, and the working end of the second electromagnetic damper 17 is attached to the bottom surface of the top plate 18; one end of the third damping spring 19 is connected to the top plate 18; both ends of the upper partition 20 are connected to the support component through mounting components, and the other end of the third damping spring 19 is connected to the bottom surface of the upper partition 20; the sensor group includes two acceleration sensors 21, a displacement sensor 22, a strain sensor 23 and a temperature sensor 24. The two acceleration sensors 21 are respectively installed on the upper partition 20 and the lower partition 10, the displacement sensor 22 is set on the lower partition 10, the strain sensor 23 is respectively set on the first rubber plate 12, the second rubber plate 15 and the top plate 18, and the temperature sensor 24 is set on the lower partition 10.

[0019] By employing the above structure and connecting the first and second vibration isolation components in series, the system can adapt to vibration waves of different frequency bands, reduce the total damping and transmission coefficient of the vibration isolation bearing, thereby better reducing energy transmission and loss, and ultimately improving vibration isolation efficiency. Furthermore, the adjustable characteristics of the electromagnetic damper, combined with the damping spring, allow for real-time adjustment of the damping ratio of the vibration isolation bearing according to the characteristics of the vibration wave, thus enhancing the vibration isolation effect and stability. Additionally, a sensor array monitors the working status and damage level of the vibration isolation bearing in real time, improving its safety and maintainability, enabling personnel to promptly identify and replace any damage to the bearing.

[0020] Specifically, by setting two acceleration sensors 21, the acceleration difference between the upper partition 20 and the lower partition 10 is monitored, thereby more accurately monitoring the vibration isolation performance of the vibration isolation support; the displacement change between the upper partition 20 and the lower partition 10 is monitored by a position sensor, thereby reflecting the deformation degree and stability between the upper partition 20 and the lower partition 10; the strain sensor 23 reflects the strain change of the first rubber plate 12, the second rubber plate 15 and the top plate 18 under vibration, thereby evaluating the vibration isolation effect and safety of the vibration isolation support; the temperature sensor 24 detects the temperature change of the vibration isolation support, thereby realizing the temperature rise of the vibration isolation support under vibration, thus reflecting the energy dissipated by the vibration isolation support and the effect of vibration isolation. The greater the temperature rise, the more energy dissipated by the vibration isolation support, and the better the vibration isolation effect.

[0021] Specifically, the strain sensor 23 is used in conjunction with the electromagnetic damper, thereby adjusting the damping force of the damper in real time according to the output signal of the strain sensor 23, so as to adapt it to the action of different vibration waves.

[0022] Specifically, the acceleration sensor 21 is an ADXL213 type acceleration sensor 21, the displacement sensor 22 is an SLPT10 type displacement sensor 22, and the strain sensor 23 is a VL219-50t type strain load sensor.

[0023] Specifically, the models of the electromagnetic damper and temperature sensor 24 are the same as those of conventionally used electromagnetic dampers and temperature sensors 24.

[0024] In embodiments of the present invention, such as Figures 1-5 As shown, the support assembly includes: two upright plates 25 and a sliding groove 26; the two upright plates 25 are respectively disposed on both sides of the first rubber plate 12; the sliding groove 26 is disposed on the inner side of the upright plates 25.

[0025] Determine the positions of the two uprights 25 so that the upper partition 20 can be fixed later.

[0026] In embodiments of the present invention, such as Figures 1-5 As shown, it also includes: two first sliders 27 and two second sliders 28; the two first sliders 27 are respectively connected to both sides of the second rubber plate 15, and the two first sliders 27 are respectively embedded in the slide groove 26; the two second sliders 28 are respectively connected to both sides of the top plate 18, and the two second sliders 28 are respectively embedded in the slide groove 26.

[0027] By passing the second rubber plate 15 through the mounting rod 11 and moving the first slider 27 along the slide groove 26, the installation of the second rubber plate 15 is guided. Similarly, by passing the top plate 18 through the mounting rod 11 and moving the second slider 28 along the slide groove 26, the installation of the top plate 18 is guided.

[0029] By passing the threaded rod 30 at the bottom of the upper partition 20 through the connecting plate 29 and fixing it with the first fastener 31, the position of the upper partition 20 is fixed. This connection method also allows workers to disassemble and replace parts.

[0030] In embodiments of the present invention, such as Figures 1-5 As shown, it also includes: a first filter hole 32, a second filter hole 33, at least two drainage channels 34 and a guide plate 35; the first filter hole 32 is respectively disposed on the upper partition 20, the lower partition 10, the top plate 18, the first rubber plate 12 and the second rubber plate 15; the second filter hole 33 is respectively disposed at the bottom of the two vertical plates 25; at least two drainage channels 34 are respectively disposed on both sides of the lower partition 10; the guide plate 35 is at a predetermined angle and is disposed in the drainage channel 34.

[0031] The first filter hole 32 and the second filter hole 33 prevent water from seeping into the vibration isolation bearing after it has been soaked in water or rainwater and unable to drain, which could cause deformation, aging or cracking of the vibration isolation bearing. They can also effectively prevent the vibration isolation bearing from expanding or contracting due to changes in air pressure inside the vibration isolation bearing under temperature changes or vibration, which could cause the displacement or strain of the vibration isolation bearing to exceed its bearing capacity and thus affect the stability of the vibration isolation bearing.

[0032] Specifically, the drainage channel 34 and the guide plate 35 are used in combination to accelerate the drainage of water dripping onto the lower partition 10.

[0034] By adjusting the positions of the second fixing member 36 and the third fixing member 37 on the mounting rod 11, the positions of the third electromagnetic damper 40 and the fourth electromagnetic damper 41 are determined, so that the third electromagnetic damper 40 and the fourth electromagnetic damper 41 can be used in conjunction with the first electromagnetic damper 14 and the second electromagnetic damper 17, thereby improving the vibration isolation effect of the vibration isolation support.

[0035] In embodiments of the present invention, such as Figures 1-5 As shown, it also includes: steel bars 38; steel bars 38 are evenly arranged at the first rubber plate 12, and one end of steel bars 38 passes through the second rubber plate 15 and the top plate 18 in sequence.

[0036] The purpose of adding 38 steel bars is to enhance the tensile stiffness and bearing capacity of the vibration isolation bearing.

[0037] In an embodiment of the present invention, the surfaces of the upper partition 20, the lower partition 10, the mounting rod 11, the first fixing member 31, the second fixing member 36, and the third fixing member 37 are all coated with an anti-corrosion coating.

[0038] By coating metal components with an anti-corrosion coating, damage such as corrosion, oxidation, and wear can be prevented, thereby enabling the vibration isolation bearing to resist the erosion of various environmental factors and extending the service life of the vibration isolation bearing.

[0039] In an embodiment of the present invention, the surfaces of the first rubber plate 12, the second rubber plate 15, the top plate 18, and the vertical plate 25 are all coated with a fireproof layer.

Furthermore, the adjustable characteristics of the electromagnetic damper, combined with the damping spring, allow for real-time adjustment of the damping ratio of the vibration isolation bearings according to the characteristics of the vibration waves, enhancing the vibration isolation effect and stability. Additionally, a sensor array monitors the working status and damage level of the vibration isolation bearings in real time, improving their safety and maintainability, enabling staff to promptly identify wear and tear and replace them as needed.
