Description
Technical Field
[0001] This invention relates to the field of vacuum unit installation technology, specifically a noise reduction and vibration damping integrated installation buffer support structure for vacuum units. Background Technology
[0002] A vacuum unit is a device that creates a vacuum environment within a certain space by utilizing physical principles (such as compressed air, pump suction, etc.). Its main function is to reduce air pressure in order to extract gases, bubbles, liquids, etc. Vacuum units are widely used in many fields in industry and scientific research, including but not limited to manufacturing, packaging, chemical, pharmaceutical and food processing.
[0003] During operation, vacuum units generate vibrations that can affect the surrounding environment, equipment, and workers, and reduce the lifespan of the vacuum unit. Therefore, it is necessary to buffer and dampen the vacuum unit during operation. For example, Chinese patent discloses a diesel generator set buffer support device (authorization announcement number CN108547699B). This patented technology, through the setting of support columns, support feet, and rotating chamfers at the support feet, allows the invention to switch between support and pulley operation as needed, enabling the invention to both move and be fixed in the required position. The invention, through the setting of buffer components, can disperse and buffer the impact on the diesel generator on the buffer plate.
[0004] However, existing units have a simple structure during buffering, which can only achieve basic impact dispersion and has limited noise reduction effect. This fails to meet the buffering and vibration reduction requirements for long-term stable operation of vacuum units, and their poor structural adaptability reduces the unit's service life. Therefore, those skilled in the art have provided a noise-reducing and vibration-damping integrated buffer support structure for vacuum units to solve the problems mentioned in the background. Summary of the Invention
[0005] The purpose of this invention is to provide an integrated installation buffer support structure for a noise-reducing and vibration-damping vacuum unit to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A noise reduction and vibration damping type vacuum unit integrated installation buffer support structure includes a base and an installation plate set on the base for installing the vacuum unit. A connecting seat is installed on the lower surface of the installation plate, and a buffer seat is set on the upper surface of the base below the connecting seat. A lifting plate is connected to the lower surface of the connecting seat inside the buffer seat, and a first buffer column is symmetrically arranged inside the buffer seat below the lifting plate. A fixing plate is also provided at the upper surface end face of the base. A fixing rod is symmetrically connected between one side of the fixing plate and the buffer seat. A first spring is sleeved on the outside of the fixing rod, and a movable sleeve slides on one side of the first spring on the outside of the fixing rod. The lower surface of the mounting plate is provided with two sets of guide plates, and a first rotating shaft is rotatably connected between the two sets of guide plates. A rotating plate is sleeved on the outside of the first rotating shaft, and a connecting plate is installed on the outside of the movable sleeve. A second rotating shaft is rotatably installed between the two connecting plates.
[0007] As a further embodiment of the present invention: the lifting plate is slidably connected to the inner wall of the buffer seat, and the two ends of the first buffer column are fixedly connected to the lower surface of the lifting plate and the inner bottom wall of the buffer seat, respectively.
[0008] As a further embodiment of the present invention: the upper surface of the buffer seat is provided with a first buffer pad, and the upper surface of the first buffer pad is fitted to the lower surface of the mounting plate.
[0009] As a further embodiment of the present invention: one end of the fixing rod is fixedly connected to the fixing plate, and the other end of the fixing rod is fixedly connected to the side wall of the buffer seat.
[0010] As a further embodiment of the present invention: the upper surface of the guide plate is fixedly connected to the lower surface of the mounting plate, and an upright plate is installed on the upper surface of the base outside the guide plate, and a sliding groove that slides with the guide plate is opened inside the upright plate.
[0011] As a further embodiment of the present invention: the movable sleeve has a sliding hole inside, and the movable sleeve is slidably connected to the fixed rod through the sliding hole.
[0012] As a further aspect of the present invention: a second buffer pad is provided on the lower surface of the lifting plate, and the material of the second buffer pad is sponge.
[0013] As a further embodiment of the present invention: one end of the first spring is fixed to one side of the fixed plate, and the other end of the first spring is fixed to one side of the movable sleeve.
[0014] As a further embodiment of the present invention: damping bearings are provided at the connection points between the two ends of the second rotating shaft and the connecting plate.
[0015] As a further embodiment of the present invention: the upper surface of the buffer seat is provided with a guide groove, and the connecting seat is slidably installed inside the guide groove.
[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a dual buffer structure combining vertical and horizontal elements. It achieves multi-level buffering of vertical vibration through a buffer seat, a first buffer column, and a second buffer pad, and achieves buffering of horizontal vibration through a fixed rod, a first spring, and a movable sleeve. This effectively reduces vibration transmission during vacuum unit operation and improves the unit's service life. At the same time, the damping effect of the first and second buffer pads reduces the noise generated by vibration, solving the problems of poor noise reduction effect and insufficient adaptability of existing buffer devices.
[0017] 2. The present invention sets the guide plate and the vertical plate together to guide and limit the vertical movement of the mounting plate, which can prevent the mounting plate from shifting or shaking and ensure the stability of the vacuum unit after installation. At the same time, the linkage between the moving sleeve, the connecting plate and the rotating shaft can convert vertical vibration into lateral buffering, further improving the stability of the overall buffer structure and reducing structural fatigue.

Detailed Implementation
[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Please see Figures 1-8 In this embodiment of the invention, a noise reduction and vibration damping type vacuum unit integrated installation buffer support structure includes a base 1 and an installation plate 3 set on the base 1 for installing the vacuum unit. A connecting seat 22 is installed on the lower surface of the installation plate 3. The base 1 serves as the foundation of the entire support structure and is made of stainless steel. Several anti-slip protrusions are evenly arranged on the lower surface, which can increase the friction between the base 1 and the installation surface, prevent the support structure from sliding as a whole, and ensure the stability of the vacuum unit during operation. A buffer seat 2 is provided on the upper surface of the base 1 below the connecting seat 22. The buffer seat 2 adopts a hollow cavity structure, and its interior is arranged corresponding to the connecting seat 22 to accommodate the lifting plate 23 and the first buffer column 24, so as to realize the vertical buffer function. The lifting plate 23 is connected to the lower surface of the connecting seat 22 inside the buffer seat 2, and the first buffer column 24 is symmetrically arranged inside the buffer seat 2 below the lifting plate 23. A fixing plate 41 is also provided at the end face of the upper surface of the base 1. A fixing rod 42 is symmetrically connected between one side of the fixing plate 41 and the buffer seat 2. A first spring 421 is sleeved on the outside of the fixing rod 42, and a movable sleeve 44 slides on one side of the first spring 421 on the outside of the fixing rod 42. The lower surface of the mounting plate 3 is provided with two sets of guide plates 431, and a first rotating shaft 432 is rotatably connected between the two sets of guide plates 431. A rotating plate 4 is sleeved on the outside of the first rotating shaft 432, and a connecting plate 45 is installed on the outside of the movable sleeve 44. A second rotating shaft 451 is rotatably installed between the two connecting plates 45.
[0022] Specifically, in this embodiment, the lifting plate 23 is slidably connected to the inner wall of the buffer seat 2. The outer diameter of the lifting plate 23 is fitted with the inner diameter of the inner cavity of the buffer seat 2 with a clearance of 0.5-1mm to ensure that the lifting plate 23 can slide smoothly up and down along the inner wall of the buffer seat 2, avoiding jamming that would affect the buffering effect. The two ends of the first buffer column 24 are fixedly connected to the lower surface of the lifting plate 23 and the inner bottom wall of the buffer seat 2, respectively. The lower surface of the lifting plate 23 is also provided with a second buffer pad 25. The material of the second buffer pad 25 is sponge, and its surface is in contact with the inner bottom wall of the buffer seat 2. It can assist the first buffer column 24 in achieving vertical secondary buffering and absorb some vibration noise. The upper surface of the buffer seat 2 is provided with a guide groove. The connecting seat 22 is slidably installed inside the guide groove, which can limit the lateral displacement of the connecting seat 22 and prevent the mounting plate 3 from shifting horizontally. At the same time, it does not affect the vertical buffering movement of the connecting seat 22 with the lifting plate 23.
[0023] Specifically, in this embodiment, a first buffer pad 21 is provided on the upper surface of the buffer seat 2. The upper surface of the first buffer pad 21 is attached to the lower surface of the mounting plate 3. The first buffer pad 21 is made of nitrile rubber with a thickness of 8-12mm and the surface is treated with anti-slip treatment. On the one hand, it can absorb the vibration transmission between the mounting plate 3 and the buffer seat 2, and on the other hand, it can reduce the friction noise caused by vibration between the two. At the same time, it plays a role in supporting the mounting plate 3 and improving the uniformity of force on the mounting plate 3.
[0024] Specifically, in this embodiment, one end of the fixing rod 42 is fixedly connected to the fixing plate 41, and the other end of the fixing rod 42 is fixedly connected to the side wall of the buffer seat 2. One end of the first spring 421 is fixed to one side of the fixing plate 41, and the other end of the first spring 421 is fixed to one side of the movable sleeve 44, so as to ensure that the first spring 421 can be compressed or stretched as the movable sleeve 44 slides, thereby achieving lateral buffering.
[0025] Specifically, in this embodiment, the upper surface of the guide plate 431 is fixedly connected to the lower surface of the mounting plate 3. The upper surface of the base 1 is equipped with a vertical plate 43 on the outside of the guide plate 431. The interior of the vertical plate 43 is provided with a sliding groove that slides with the guide plate 431. The width of the sliding groove is matched with the thickness of the guide plate 431. The guide plate 431 can slide up and down along the sliding groove to provide guidance for the vertical movement of the mounting plate 3, prevent the mounting plate 3 from tilting, ensure a smooth buffering process, and an elastic element can be set inside the sliding groove to achieve the purpose of buffering again.
[0026] Specifically, in this embodiment, the movable sleeve 44 has a sliding hole inside, and the movable sleeve 44 is slidably connected to the fixed rod 42 through the sliding hole. The inner diameter of the sliding hole is in clearance fit with the outer diameter of the fixed rod 42 (the clearance is 0.3-0.5mm). The movable sleeve 44 is slidably connected to the fixed rod 42 through the sliding hole, ensuring that the movable sleeve 44 can slide smoothly along the fixed rod 42 without jamming or offset, thus ensuring the smoothness of lateral buffering.
[0027] Specifically, in this embodiment, damping bearings are provided at the connection points between the two ends of the second rotating shaft 451 and the connecting plate 45. These bearings can provide a certain damping force to slow down the rotation speed of the connecting plate 45, preventing the connecting plate 45 from rotating rapidly due to excessive vibration frequency, thereby generating secondary vibration. At the same time, the damping bearings can absorb some of the noise generated during rotation, improving the overall noise reduction effect.
[0028] The working principle of this invention is as follows: The specific working process of the integrated installation buffer support structure of the noise reduction and vibration damping vacuum unit of this invention is as follows: When the vacuum unit is running, vertical vibrations are generated. These vibrations are transmitted to the connecting seat 22 through the mounting plate 3. The connecting seat 22 then transmits the vibrations to the lifting plate 23 below. Since the lifting plate 23 is slidably connected to the inner wall of the buffer seat 2, and the first buffer column 24 is symmetrically arranged below the lifting plate 23, the vibrations force the lifting plate 23 to slide downwards along the inner wall of the buffer seat 2, thereby compressing the first buffer column 24. The first buffer column 24 undergoes elastic deformation during the compression process, converting the kinetic energy of the vertical vibration into elastic potential energy, thus achieving the first vertical buffer. At the same time, the second buffer pad 25 (high-density sponge) on the lower surface of the lifting plate 23 will adhere and squeeze against the inner bottom wall of the buffer seat 2, further absorbing the remaining vertical vibration energy, thus achieving the second vertical buffer and effectively weakening the transmission of vertical vibrations. In addition, the first buffer pad 21 (nitrile rubber) on the upper surface of the buffer seat 2 can absorb the vibration between the mounting plate 3 and the buffer seat 2, reducing the noise generated by the friction between the two. In addition, the lateral vibration generated during the operation of the vacuum unit will be transmitted to the guide plate 431 through the mounting plate 3. The guide plate 431 will move slightly laterally along the slide groove of the vertical plate 43 (or drive the mounting plate 3 to move slightly laterally). Then, the rotation of the first rotating shaft 432 and the second rotating shaft 451 will cause the rotating plate 4 to tilt. At the same time, the moving sleeve 44 will slide along the guide of the fixed rod 42, which will squeeze or stretch the first spring 421 on one side. The first spring 421 will undergo elastic deformation, converting the kinetic energy of the lateral vibration into elastic potential energy, thus achieving lateral buffering. It should be added that the noise reduction effect of this structure is mainly achieved through two aspects. First, the first buffer pad 21, the second buffer pad 25, the first buffer column 24 and other buffer components absorb vibration energy, reduce vibration transmission, and thus reduce structural noise caused by vibration.
