Description

Technical Field

[0001] This utility model relates to the technical field of spring-damped composite vibration reduction equipment, and in particular to a spring-damped composite vibration reduction base for an oxygen generator air compressor. Background Technology

[0002] Oxygen air compressors generate vibrations during operation, which can easily lead to equipment displacement and damage to the ground. Therefore, multiple spring-damped composite vibration-damping bases are installed at the bottom of the oxygen air compressor. These bases are supported by a high-strength frame and use metal springs to buffer vibration impacts. Combined with hydraulic dampers and modified rubber blocks to dissipate energy, and equipped with sensors and an intelligent control system, they can adaptively adjust parameters to adapt to different working conditions, significantly reducing vibration transmission rate. They also feature a modular design to improve adaptability and maintainability, ensuring stable operation of the equipment.

[0003] However, traditional vibration damping structures mostly focus on longitudinal vibration control, while lateral vibration is prone to accumulate and cause equipment displacement or component loosening, posing a great safety hazard. Furthermore, if only a single spring or rubber damping is used, mid-frequency vibration (such as the main vibration frequency band of the equipment's steady-state operation) may continue to be transmitted because the energy is not fully dissipated, resulting in reduced vibration mitigation efficiency and affecting the operation of the equipment and the surrounding environment. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A spring-damped composite vibration damping base for an oxygen generator air compressor includes a vibration damping pad. Two guide metal blocks are fixedly installed on the top of the vibration damping pad, and friction damping pads are fixedly installed on the outer sides of the two guide metal blocks. A polyurethane buffer block is fixedly installed on the top of the vibration damping pad, and a damping plate is fixedly installed on the top of the polyurethane buffer block.

[0006] Specifically, the top of the polyurethane buffer block has four guide holes, and polytetrafluoroethylene guide cylinders are fixedly installed on the inner side of each of the four guide holes.

[0007] Specifically, four helical springs are fixedly installed on the top of the shock-absorbing pad. The four helical springs are located inside the corresponding polytetrafluoroethylene guide cylinders. The polytetrafluoroethylene guide cylinders can guide the compression or rebound direction of the helical springs to prevent them from deviating.

[0008] Specifically, an alloy shell is fixedly installed on the top of the damping plate, and the inner wall of the alloy shell abuts against two friction damping pads to facilitate the reduction of lateral vibration force.

[0009] Specifically, an oil sleeve is fixedly installed on the top of the shock-absorbing pad, and the inside of the oil sleeve is filled with buffer oil.

[0010] Specifically, a piston rod is fixedly installed at the bottom of the damping plate, one end of the piston rod extends into the inner side of the oil sleeve, and a nitrile rubber ring is slidably sleeved on the piston rod. The bottom of the nitrile rubber ring is fixedly connected to the top of the oil sleeve to prevent rigid collision between the piston rod and the oil sleeve.

[0011] Specifically, a piston head is fixedly installed on one end of the piston rod that extends into the oil sleeve. The top of the piston head has multiple damping holes, which generate viscous resistance when the buffer oil passes through the multiple damping holes on the surface of the piston head.

[0012] Specifically, a disc spring is fitted on the outer side of the oil sleeve. The upper and lower ends of the disc spring are fixedly connected to the top of the shock-absorbing pad and the bottom of the damping plate, respectively. The disc spring is used to prevent rigid collision between the alloy shell and the shock-absorbing pad.

[0013] Specifically, a glass fiber reinforced resin base is fixedly installed on the top of the alloy shell, which can enhance the overall structural strength of the rubber damping block and the alloy shell.

[0014] Specifically, a rubber damping block is fixedly installed on the top of the glass fiber reinforced resin base. The flexible deformation of the rubber damping block can directly absorb most of the high-frequency vibration energy, and at the same time, it can buffer the instantaneous impact force during startup through its own elasticity.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a friction damping pad between the alloy shell and the guide metal block, the lateral vibration is converted into frictional energy dissipation, solving the problem of uncontrolled lateral vibration, thereby preventing the equipment from shifting or the parts from loosening due to lateral vibration, and enhancing the safety of the equipment. At the same time, by setting a damping plate, piston rod, piston head and oil sleeve, the viscous resistance and internal friction of the oil are used to specifically enhance the attenuation of medium frequency vibration, effectively improving the vibration mitigation efficiency of the equipment, and improving its practicality and stability.

[0022] Reference Figure 1-5 A spring-damped composite shock absorber base for an oxygen generator air compressor includes a shock absorber pad 1, two guide metal blocks 2 are fixedly installed on the top of the shock absorber pad 1, and friction damping pads 3 are fixedly installed on the outer sides of the two guide metal blocks 2; a polyurethane buffer block 4 is fixedly installed on the top of the shock absorber pad 1, and a damping plate 13 is fixedly installed on the top of the polyurethane buffer block 4.

[0023] In this embodiment, the top of the polyurethane buffer block 4 is provided with four guide holes 5, and polytetrafluoroethylene guide cylinders 6 are fixedly installed on the inner side of each of the four guide holes 5.

[0024] In this embodiment, four helical springs 7 are fixedly installed on the top of the shock-absorbing pad 1. The four helical springs 7 are located inside the corresponding polytetrafluoroethylene guide cylinder 6. The polytetrafluoroethylene guide cylinder 6 can guide the compression or rebound direction of the helical springs 7 to prevent them from deviating.

[0025] In this embodiment, an alloy shell 14 is fixedly installed on the top of the damping plate 13. The inner wall of the alloy shell 14 abuts against the two friction damping pads 3, which facilitates the reduction of lateral vibration force.

[0026] In this embodiment, an oil sleeve 9 is fixedly installed on the top of the shock-absorbing pad 1, and the inside of the oil sleeve 9 is filled with buffer oil.

[0027] In this embodiment, a piston rod 12 is fixedly installed at the bottom of the damping plate 13. One end of the piston rod 12 extends into the inner side of the oil sleeve 9. A nitrile rubber ring 10 is slidably sleeved on the piston rod 12. The bottom of the nitrile rubber ring 10 is fixedly connected to the top of the oil sleeve 9 to prevent rigid collision between the piston rod 12 and the oil sleeve 9.

[0028] In this embodiment, a piston head 11 is fixedly installed on one end of the piston rod 12 that extends into the oil sleeve 9. The top of the piston head 11 is provided with multiple damping holes, and the buffer oil generates viscous resistance when passing through the multiple damping holes on the surface of the piston head 11.

[0029] In this embodiment, a disc spring 8 is sleeved on the outer side of the oil sleeve 9. The upper and lower ends of the disc spring 8 are fixedly connected to the top of the shock-absorbing pad 1 and the bottom of the damping plate 13, respectively. The disc spring 8 is used to prevent rigid collision between the alloy shell 14 and the shock-absorbing pad 1.

[0030] In this embodiment, a glass fiber reinforced resin base 15 is fixedly installed on the top of the alloy shell 14, which can enhance the overall structural strength of the rubber damping block 16 and the alloy shell 14.

[0031] In this embodiment, a rubber damping block 16 is fixedly installed on the top of the glass fiber reinforced resin base 15. The flexible deformation of the rubber damping block 16 can directly absorb most of the high-frequency vibration energy, and at the same time, it can buffer the instantaneous impact force during startup through its own elasticity.

[0032] Working principle: When the air compressor is running, the vibration generated is first transmitted from top to bottom to the rubber damping block 16. The flexible deformation of the rubber damping block 16 can directly absorb most of the high-frequency vibration energy, converting the vibration energy into heat energy through intermolecular friction. At the same time, its own elasticity buffers the instantaneous impact force during startup, preventing hard impact from being directly transmitted to the glass fiber reinforced resin base 15. The natural frequency of the resin material is low, which can avoid the low-frequency fundamental frequency of the air compressor and prevent resonance amplification. Subsequently, the vibration is transmitted to the alloy shell 14. The inner wall of the alloy shell 14 is close to the two guide metal blocks 2. A friction damping pad 3 is provided between the alloy shell 14 and the two guide metal blocks 2, which can convert the lateral vibration into pressure on the friction damping pad 3, further dissipating energy through friction. At the same time, the vibration drives the piston rod 12 to drive the piston head 11 to reciprocate within the oil sleeve 9. When the oil passes through multiple damping holes on the surface of the piston head 11, it generates viscous resistance. The damping plate 13 moves with the piston rod 12, further cutting the oil flow field, increasing the internal friction of the oil, and dissipating the vibration energy through oil heating. It is particularly good at attenuating medium-frequency vibration. When the helical spring 7 and disc spring 8 are impacted, they are compressed and absorb the impact force through elastic deformation. When the vibration energy weakens, the helical spring 7 and disc spring 8 release elastic potential energy and push the equipment to reset. Then, they absorb the continuous vibration energy through small deformation. At this time, after being weakened by the multi-stage structure, the residual impact force is transmitted to the ground through the damping pad 1. The damping pad 1 further absorbs the residual vibration energy that has not been completely eliminated through its own elastic damping layer, reducing the impact force transmitted to the ground, while blocking the interference of the reverse vibration of the ground on the equipment, ensuring the stable operation of the equipment and the safety of the ground foundation.

[0033] The technological advancements of this invention compared to existing technologies are as follows: By using the friction damping pad 3 between the alloy shell 14 and the guide metal block 2, lateral vibration is converted into frictional energy dissipation, solving the problem of uncontrolled lateral vibration and preventing equipment displacement or component loosening caused by lateral vibration, thus enhancing equipment safety. At the same time, by using the damping plate 13, piston rod 12, piston head 11, and oil sleeve 9, viscous resistance and internal friction of the oil are utilized to specifically enhance the attenuation of medium-frequency vibration, effectively improving the vibration mitigation efficiency of the equipment and enhancing its practicality and stability.
