Description

Technical Field

[0001] The utility model belongs to the technical field of compressor transportation vibration reduction, and particularly relates to a compressor transportation vibration reduction device. Background Art

[0002] Compressors, a vital piece of equipment widely used in industrial, commercial, and household applications, contain numerous precision components, such as the motor, cylinder, piston, and crankshaft. These components must work together with high precision during operation to ensure proper function and efficient performance. However, during transportation, compressors are subject to the inevitable vibrations, shocks, and bumps of transportation vehicles (such as trucks, trains, and ships). These external forces can easily damage the compressor, severely impacting its quality and reliability, increasing costs for the company and potentially delaying production or delivery cycles.

[0003] Traditional compressor transportation methods typically involve simply placing the compressor on a pallet or wooden box and securing it with ropes or steel straps. This simple packaging and securing method may be effective for general cargo transportation, but for precision and vibration-sensitive equipment like compressors, it falls far short of meeting the vibration reduction requirements during transportation. During transportation, high-frequency vibrations generated by uneven road surfaces are directly transmitted to the compressor, potentially causing internal components to loosen, wear, deform, or even damage. For example, vibration can cause friction between the motor's rotor and stator, affecting the motor's performance and lifespan. Precision valve components can deform due to impact, resulting in reduced cooling or heating efficiency. Connecting pipes can crack due to vibration fatigue, leading to serious problems such as refrigerant leaks.

[0004] With the continuous improvement of modern manufacturing's requirements for product quality and reliability, as well as the rapid development of the logistics and transportation industry, there is an urgent need for an efficient vibration reduction device specifically for compressor transportation to reduce the impact of vibration and impact on the compressor during transportation, ensuring that the compressor can still maintain good performance and accuracy after transportation, thereby ensuring the normal operation of the entire industry chain and reducing operating costs.

[0005] While there have been some research and developments in the field of vibration reduction technology in recent years, such as the use of traditional vibration reduction components such as rubber vibration damping pads and spring vibration dampers to reduce vibration transmission, these conventional vibration reduction devices still have many limitations when used in compressor transportation. Rubber vibration damping pads are prone to aging and hardening after being subjected to high pressure and high-frequency vibration for a long time, resulting in a gradual decrease in vibration reduction effect. The vibration reduction frequency of spring vibration dampers is relatively fixed, making it difficult to adapt to the complex and changing vibration frequencies during transportation. In addition, their buffering performance in large impact situations is limited and cannot fully protect the compressor from severe impact. In addition, a single vibration reduction component often only works well within a specific vibration frequency range, making it difficult to effectively suppress broadband vibration during compressor transportation.

[0006] In summary, the development of a new type of compressor transport vibration reduction device with good adaptability and high-efficiency vibration reduction performance has extremely important practical significance. Utility Model Content

[0007] In response to the shortcomings of the existing technology, the utility model proposes a compressor transportation vibration reduction device, which can effectively reduce the vibration amplitude and impact intensity of the compressor, greatly improve the overall vibration reduction efficiency, and better protect the pipelines connected to the compressor from damage.

[0008] The technical solution of the present utility model is achieved as follows:

[0009] A vibration damping device for a compressor, wherein the compressor is arranged on a base plate through the vibration damping device, the vibration damping device includes a vibration damping element and four vibration damping pressure feet, the four vibration damping pressure feet are fixed at the four corners of the first bottom surface of the compressor, the bottoms of the four vibration damping pressure feet are in contact with the base plate, the vibration damping element is arranged between the compressor and the base plate, the vibration damping element includes a first end and a second end, the height of the first end is higher than the height of the second end, the vibration damping element is provided with a plurality of grooves, the plurality of grooves are arranged between the first end and the second end, a first side plate is extended downward from the first bottom surface, and the first side plate is in contact with the grooves.

[0010] Preferably, the shock absorbing element includes a second bottom surface, two second side plates vertically arranged on both sides of the second bottom surface, and a third side plate vertically arranged on the second bottom surface and between the two second side plates, and a plurality of grooves are arranged on the top of the two second side plates.

[0011] Preferably, the height of the first end is 2-5 cm higher than the height of the second end.

[0012] Preferably, a bayonet is provided on the second bottom surface.

[0013] Preferably, there are four shock-absorbing elements, and first side plates extend downward from four edges of the first bottom surface. The four shock-absorbing elements are in contact with the four first side plates respectively.

[0014] Preferably, notches are formed at four corners of two adjacent first side panels and the first bottom surface.

[0015] Compared with the existing technology, the present invention has the following advantages.

[0016] In this embodiment, by providing a damping element with a height of its first end higher than its second end, external forces cause the compressor to move in a certain direction along an inclination. When vibrations generated by the compressor are transmitted to the damping element during operation, this inclination causes uneven elastic deformation of the damping element. This deformation causes the damping element (made of a damping material such as rubber) to generate varying degrees of stress and strain in different locations, thereby increasing frictional losses within the damping material and more efficiently dissipating vibration energy into other forms such as heat. Furthermore, the presence of several grooves on the damping element creates a convex-concave surface. When the bottom of the compressor slides over the convex-concave surface, the raised portions of the surface exert an upward force on the compressor, hindering its downward movement. The concave portions, however, cause the compressor to briefly accelerate downward, only to encounter resistance from the next raised portion. By continuously varying the magnitude and direction of the resistance, the compressor's vibration energy is converted into work required to overcome the resistance of the convex-concave surface, effectively dissipating the vibration energy and achieving a vibration reduction effect.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Furthermore, the terms "first," "second," "third," and "fourth," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0028] See also Figures 1 to 2 The embodiment of the utility model discloses a transportation vibration reduction device for a compressor, wherein the compressor 4 is arranged on a base plate 1 through the vibration reduction device, and the vibration reduction device includes a vibration reduction element 2 and four vibration reduction pressure feet 3. The four vibration reduction pressure feet are fixed at the four corners of the first bottom surface 41 of the compressor 4, and the bottom of the vibration reduction pressure feet 3 is in contact with the base plate 1, wherein the vibration reduction pressure feet 3 can effectively absorb and buffer the vibration generated by the transportation of the compressor, thereby preventing the compressor 4 from directly bearing severe vibration impact.

[0029] Specifically, the shock-absorbing element 2 includes a first end 21 and a second end 22, the height of the first end 21 is higher than the height of the second end 22, and the height of the first end 21 is 2-5 cm higher than the height of the second end 22. The shock-absorbing element 2 is provided with a plurality of grooves 23, and the plurality of grooves 23 are arranged between the first end 21 and the second end 22. The first bottom surface 41 extends downwardly with a first side plate 42, and the first side plate 42 is in contact with the groove 23.

[0030] In this embodiment, by providing a damping element 2 with its first end 21 2-5 cm higher than its second end 22, external forces cause the compressor 4 to move in a certain direction along an inclination. When vibrations generated by the compressor are transmitted to the damping element 2 during operation, this inclination causes uneven elastic deformation of the damping element. This deformation causes the damping element (made of a damping material such as rubber) to generate varying degrees of stress and strain in different locations, thereby increasing frictional losses within the damping material and more efficiently dissipating vibration energy into other forms such as heat. Furthermore, because the damping element 2 is provided with a plurality of grooves 23, a convex-concave surface is formed on the damping element 2. When the bottom of the compressor 4 slides on this surface, the raised portions of the surface exert an upward force on the compressor 2, hindering its downward movement. The concave portions, on the other hand, cause the compressor 4 to briefly accelerate downward movement, only to be immediately blocked by the next raised portion. In this way, by constantly changing the size and direction of the resistance, the vibration energy of the compressor 4 is converted into work done to overcome the resistance of the convex and concave surfaces, thereby effectively consuming the vibration energy, reducing the vibration amplitude and impact intensity of the compressor, greatly improving the overall vibration reduction efficiency, and better protecting the pipelines connected to the compressor from damage.

[0031] The four vibration-damping pressure feet 3 are located at the four corners of the first bottom surface 41 of the compressor 4, and work together with the shock-absorbing element 2 to ensure the stable placement of the compressor 4 on the base plate 1 and prevent it from displacement or shaking during operation, and can also buffer and disperse the vibration from different parts, making the overall shock-absorbing effect more uniform and reliable, which is beneficial to the long-term stable operation of the compressor 4, reducing the loosening and wear of components caused by vibration, and extending the service life of the compressor 4.

[0032] Specifically, there are four shock-absorbing elements 2 , and first side plates 42 extend downward from four edges of the first bottom surface 41 . The four shock-absorbing elements 2 are in contact with the four first side plates 42 respectively.

[0033] In this embodiment, by providing four shock-absorbing elements 2, the vibration generated by the compressor can be absorbed and buffered from multiple directions simultaneously. Regardless of whether the vibration comes from the front, back, left, right, or up and down directions of the compressor, it can be effectively suppressed. Compared with the configuration of a single or a small number of shock-absorbing elements 2, this all-round shock-absorbing layout can reduce the vibration energy transmitted by the compressor 4 to the outside world, significantly reducing the equipment noise caused by vibration, creating a quieter atmosphere for the surrounding environment, which is particularly important for noise-sensitive application scenarios (such as indoor air-conditioning compressors).

[0034] Specifically, two adjacent first side plates 42 and four corners of the first bottom surface 41 form second notches 43 , thereby facilitating the clamping of the vibration-damping presser foot 3 .

[0035] Specifically, the shock absorbing element 2 includes a second bottom surface 24, two second side panels 25 vertically arranged on both sides of the second bottom surface 24, and a third side panel 26 vertically arranged on the second bottom surface 24 and between the two second side panels 25. The upper surfaces 251 of the two second side panels 25 each have a plurality of grooves 23.

[0036] In this embodiment, the three side panels and the second bottom surface 24 work together to enable the shock absorbing element 2 to more accurately disperse the force transmitted from the compressor 4 and transmit it to various parts for buffering and shock absorption when subjected to stress. In this way, the material thickness and strength of each part can be reasonably determined according to the actual stress conditions, avoiding excessive redundancy of materials in certain parts due to unreasonable structure. For example, while enhancing the stability of the structure, the third side panel 26 can cooperate with the two second side panels 25 to make the material of the second bottom surface more evenly distribute the stress when under pressure, thereby appropriately reducing the thickness or amount of the bottom surface material on the basis of ensuring the structural strength, thereby achieving material savings. The provision of several grooves 23 on the two second side panels 25 forms convex and concave surfaces on the top of the two second side panels 25. This design not only enhances the damping and shock absorption, but also avoids the addition of additional damping materials or complex damping structural components, thereby reducing material consumption overall.

[0037] Specifically, a bayonet 241 is provided on the second bottom surface 24, and the bayonet 241 is engaged with a protrusion (not shown in the figure) of the bottom plate 1, thereby preventing the left and right shaking of the compressor during long-distance transportation, which may affect the cracking of the copper pipe connected to the compressor.

[0038] The overall structural design of the vibration damping device in this embodiment is reasonable and compact. It does not require complex auxiliary structures or excessive installation space, can be easily integrated into the existing compressor installation system, is suitable for compressors of various types and specifications, has good versatility and practicality, and achieves good vibration damping function without occupying too much space resources, which is conducive to the miniaturization and integrated design of the equipment.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
