Description

Technical Field

[0001] This utility model relates to the field of compressor base technology, specifically a compressor anti-vibration base. Background Technology

[0002] As a core power component in industrial production and refrigeration equipment, the compressor generates strong vibrations and noise during operation. This not only affects the surrounding environment and the stability of equipment operation, but also accelerates the wear and tear of the compressor itself and related components, shortening its service life. Therefore, vibration-damping bases are a crucial supporting equipment for compressor installation, and their vibration reduction performance and ease of maintenance directly determine the user experience and operation and maintenance costs.

[0003] In existing technologies, compressor anti-vibration bases mostly achieve buffering and vibration reduction through built-in damping components (such as springs and rubber pads). Although this can initially reduce vibration transmission, it has significant drawbacks: the damping components are subjected to high-frequency vibration and load from the compressor for a long time, which can easily lead to fatigue aging, deformation, or even breakage, resulting in a short service life; moreover, the damping components are mostly embedded fixed structures, which require disassembling the compressor body and the entire base for maintenance or replacement, making the operation cumbersome, increasing labor costs, causing production downtime losses, and seriously affecting efficiency.

[0004] Therefore, developing a compressor anti-vibration base that allows for convenient maintenance of vibration damping components (without requiring compressor disassembly) has become an urgent need to address the pain points of existing technologies and reduce operation and maintenance costs. Utility Model Content

[0005] The purpose of this invention is to provide a compressor anti-vibration base to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A compressor anti-vibration base includes a base with a groove on its top surface. A fixed plate is fixedly installed in the groove, and a support plate is movably installed in the groove above the fixed plate. A shock-absorbing component and multiple dampers are installed between the support plate and the fixed plate. The shock-absorbing component includes multiple rubber rods evenly spaced between the fixed plate and the support plate. Strip grooves are respectively opened on the adjacent surfaces of the support plate and the fixed plate, and the rubber rods are installed between two strip grooves. Insertion holes are also opened on one side of the base corresponding to the positions of the multiple rubber rods.

[0008] As a further embodiment of this utility model: multiple dampers are respectively installed at the four corner positions of the fixed plate and the support plate, and the adjacent surfaces of the fixed plate and the support plate are symmetrically provided with mounting grooves.

[0009] As a further embodiment of this utility model: the rubber rod includes a first rubber rod and a second rubber rod, the diameter of the first rubber rod is larger than the diameter of the second rubber rod, and the first rubber rod and the second rubber rod are arranged at intervals.

[0010] As a further embodiment of this utility model: the other side of the base is provided with a positioning groove that is adapted to the first rubber rod and the second rubber rod at the position of the insertion hole.

[0011] As a further embodiment of this utility model: the support plate is also provided with an adjustment assembly, which includes a pair of movable plates movably disposed on the support plate and a pair of positioning plates installed on the movable plates. A pair of first sliding grooves are provided side by side on the support plate. A first slider adapted to the first sliding groove is installed on the bottom surface of the movable plate. First positioning bolts are also symmetrically threaded on both sides of the movable plate corresponding to the positions of the first sliding grooves. A second sliding groove is also provided on the movable plate. A second slider adapted to the second sliding groove is fixedly disposed on the bottom surface of the positioning plate. A threaded hole is provided on the positioning plate. A second positioning bolt is also threaded on the side of the positioning plate corresponding to the position of the second sliding groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model's base adopts a composite vibration reduction structure of "rubber rod + hydraulic damper". The first and second rubber rods, made of fatigue-resistant rubber, are arranged alternately. The larger-diameter first rubber rod bears the main load, while the smaller-diameter second rubber rod precisely absorbs high-frequency micro-vibrations, achieving graded vibration reduction and adapting to the vibration characteristics of the compressor under different operating conditions. The strip grooves of the fixing plate and support plate provide precise constraints on the rubber rods, preventing misalignment during vibration. Combined with the coaxial design of the positioning groove and insertion hole, this ensures the rubber rods are securely installed and do not come loose. The hydraulic dampers at the four corners have adjustable damping coefficients, effectively suppressing vibration resonance and buffering impact energy. Working synergistically with the rubber rods, they comprehensively absorb high-frequency vibrations, significantly reducing operating noise and providing a stable working environment for the compressor.

[0014] 2. In terms of maintenance, the insertion holes on the side of the base cooperate with the positioning grooves, so when replacing the rubber rod, there is no need to disassemble the compressor and the base. The old one can be directly removed and the new one inserted to complete the operation, avoiding production losses caused by long-term downtime. The anti-slip pads and the steel plate fixing plate ensure that the base is stable and does not slip, improving the safety of use.

[0015] 3. In terms of adaptability, this utility model features an adjustable support plate that allows for full-dimensional size adaptation. The movable plate slides laterally along the first slide groove to accommodate the compressor length, while the positioning plate adjusts longitudinally along the second slide groove to accommodate the width. The first and second positioning bolts are securely tightened, eliminating the need to replace the base and meeting the installation requirements of compressors of different specifications. This significantly improves versatility and reduces equipment procurement costs. The overall design balances vibration reduction reliability, ease of maintenance, and adaptability flexibility, providing efficient assurance for the stable operation of compressors in industrial production.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] Example 1

[0024] Please see Figure 1-5 A compressor anti-vibration base includes a base 1, wherein a connecting ear is fixedly provided on the side of the base 1 and is fixed to the ground by bolts to ensure that the base 1 is stable and does not slip, providing a stable support foundation for the compressor. The top surface of the base 1 is provided with a groove, which provides a precise installation space for the vibration damping component. A fixing plate 2 is fixedly provided in the groove, and a support plate 3 is movably provided above the fixing plate 2 in the groove. The fixing plate 2 is made of steel plate and is welded and fixed to the base 1. The support plate 3 directly supports the compressor body.

[0025] A shock-absorbing assembly 5 and multiple dampers 4 are installed between the support plate 3 and the fixed plate 2. The shock-absorbing assembly 5 and the dampers 4 work together to effectively absorb the high-frequency vibration of the compressor and reduce noise.

[0026] The vibration damping component 5 includes a plurality of rubber rods 6 evenly spaced between the fixed plate 2 and the support plate 3. The adjacent surfaces of the support plate 3 and the fixed plate 2 are respectively provided with strip grooves. The rubber rods 6 are installed between two strip grooves. The rubber rods 6 are made of fatigue-resistant rubber material. The strip grooves and the rubber rods 6 are fitted with a clearance to prevent the rubber rods from being misaligned or shifted when vibrating, thus ensuring vibration damping stability.

[0027] The base 1 has insertion holes 7 on one side corresponding to multiple rubber rods 6. The diameter of the insertion holes 7 is slightly larger than the outer diameter of the rubber rods 6. When replacing the rubber rods, there is no need to disassemble the compressor and the base. The old rubber rod can be pulled out directly through the insertion holes and the new rubber rod can be inserted. The replacement is convenient and solves the problem of "cumbersome maintenance and large downtime losses" in the background technology.

[0028] In this embodiment, multiple dampers 4 are respectively installed at the four corner positions of the fixed plate 2 and the support plate 3. The adjacent surfaces of the fixed plate 2 and the support plate 3 are symmetrically provided with mounting grooves 8. The dampers 4 are hydraulic dampers with adjustable damping coefficients, which can suppress vibration resonance and assist the rubber rod in absorbing impact energy.

[0029] Example 2

[0030] Please see Figure 3 and Figure 4 The rubber rod 6 includes a first rubber rod 9 and a second rubber rod 10. The diameter of the first rubber rod 9 is larger than the diameter of the second rubber rod 10, and the first rubber rod 9 and the second rubber rod 10 are spaced apart. The first rubber rod 9 bears the main load, while the second rubber rod 10 absorbs high-frequency micro-vibrations, thereby achieving graded vibration reduction and adapting to the vibration characteristics of the compressor under different operating conditions, resulting in better vibration reduction effect.

[0031] In this embodiment, the other side of the base 1 is also provided with a positioning groove 11 that is adapted to the first rubber rod 9 and the second rubber rod 10 at the position of the insertion hole 7. The positioning groove 11 is coaxially arranged with the insertion hole 7. The rubber rod is inserted into the positioning groove 11 at the rear end, which makes it more secure and prevents it from coming out during vibration. At the same time, it is convenient to quickly align during installation.

[0032] Example 3

[0033] Please see Figure 1 , Figure 2 and Figure 5 The support plate 3 is also equipped with an adjustment component, which enables the installation of compressors of different specifications without the need to replace the base, thereby improving versatility and reducing equipment costs.

[0034] The adjustment assembly includes a pair of movable plates 12 movably mounted on a support plate 3 and a pair of positioning plates 13 mounted on the movable plates 12. A pair of first sliding grooves 14 are provided side by side on the support plate 3. A first slider adapted to the first sliding groove 14 is installed on the bottom surface of the movable plate 12. First positioning bolts 15 are symmetrically threaded on both sides of the movable plate 12 corresponding to the positions of the first sliding grooves 14. The first sliding groove 14 is a T-shaped groove, and the movable plate 12 can slide laterally along it to adapt to the adjustment of the compressor length direction. The first positioning bolts 15 have a strong locking force and are firmly fixed after sliding into place to prevent loosening during use.

[0035] The movable plate 12 is also provided with a second sliding groove 16. The bottom surface of the positioning plate 13 is fixedly provided with a second slider that matches the second sliding groove 16. The positioning plate 13 is provided with a threaded hole 18. The side of the positioning plate 13 is also threaded with a second positioning bolt 17 corresponding to the position of the second sliding groove 16. The second sliding groove 16 is an elongated groove, and the positioning plate 13 can slide along its longitudinal direction to adapt to the adjustment of the compressor width direction. The threaded hole 18 is used to install the fixing bolt to lock the compressor and the positioning plate 13. The second positioning bolt 17 locks the longitudinal position of the positioning plate 13 to ensure that the compressor does not move after installation.

[0036] Working principle:

[0037] When installing the compressor, according to the size and specifications of the compressor, loosen the first positioning bolt 15, push the movable plate 12 to slide laterally along the first slide groove 14 of the support plate 3 to a suitable position, and lock the first positioning bolt 15; then loosen the second positioning bolt 17, move the positioning plate 13 to slide longitudinally along the second slide groove 16 of the movable plate 12, so that the threaded hole 18 of the positioning plate 13 is aligned with the compressor mounting hole, and fix the compressor on the positioning plate 13 with bolts to complete the installation.

[0038] When the compressor is working, the vibration generated is transmitted to the shock absorption assembly 5 and the damper 4 through the support plate 3. The first rubber rod 9 and the second rubber rod 10 deform together to absorb the main vibration energy. The damper 4 suppresses resonance and buffers the impact. The strip groove prevents the rubber rod from being misaligned, ensuring vibration reduction stability and effectively reducing noise transmission.

[0039] When the rubber rods show signs of fatigue and require maintenance, there is no need to disassemble the compressor and base. Simply pull out the old rubber rod through the insertion hole 7 on the side of the base 1, align the new first rubber rod 9 or second rubber rod 10 with the insertion hole 7, and insert it with its end embedded in the positioning groove 11. This completes the replacement process, making maintenance convenient and not affecting production progress. This design, through the synergistic effect of "graded vibration reduction + convenient maintenance + universal compatibility," solves the pain points of existing anti-vibration bases, namely "easily damaged vibration damping components and cumbersome maintenance," thereby improving the compressor's operational stability and maintenance efficiency.

[0040] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.

[0041] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
