Description

Technical Field

[0001] This utility model relates to the field of vibration reduction technology for mechanical equipment, specifically a vibration reduction device for mechanical equipment. Background Technology

[0002] Mechanical equipment is usually mounted directly on a frame. The vibrations generated during the operation of the mechanical equipment are mitigated by a simple damping structure on the frame. This simple damping structure is usually accomplished by a series of springs, or sometimes by combining air damping.

[0003] Spring damping, while mitigating the potential energy generated by equipment vibration, does not actually absorb vibration. Because this method lacks energy release, the accumulated elastic potential energy returns in the opposite direction of its generation during the spring's recovery process. This causes the equipment to vibrate vertically or resonate to a certain extent, resulting in vibration of both the equipment and the damping device. Therefore, this method does not fundamentally solve the problem of equipment vibration reduction. Utility Model Content

[0004] The purpose of this invention is to provide a shock-absorbing device for mechanical equipment to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A vibration damping device for mechanical equipment includes a base, a top seat on the top surface of the base, a spring and a buffer component connected between the base and the top seat, the spring and the buffer component being arranged in parallel, and a fixing component on the top surface of the top seat for fixing the feet of the mechanical equipment. The buffer component includes an outer sleeve mounted on the top surface of the base and a stopper rod mounted on the bottom surface of the top seat. An inner sleeve is mounted on the inner top of the outer sleeve, and a piston is mounted on the bottom end of the stopper rod. The piston slides vertically within the inner sleeve. The bottom surface of the inner sleeve has several first through holes, and the side surface of the inner sleeve has several second through holes near its top surface. Both the outer sleeve and the inner sleeve are filled with damping oil. The spring and the buffer component are arranged in parallel, with the spring providing elastic support. The buffer component, working in conjunction with the spring, effectively mitigates the impact force during equipment vibration and improves the vibration damping effect. The fixing component is used to fix the feet of the mechanical equipment, ensuring stable installation and preventing displacement during vibration damping. The buffer component utilizes damping oil and a special structure. During piston sliding, the damping oil flows between the first and second through holes, generating damping force to dissipate vibration energy and reduce the vibration amplitude of the equipment. This fundamentally improves the equipment's vibration damping performance and prevents the equipment and the damping device from vibrating together. The overall device structure is rationally designed and can effectively reduce the impact of vibrations generated during mechanical operation on the equipment itself and the surrounding environment.

[0007] Specifically, the base is fixed to the ground using bolts and other connecting parts.

[0008] Furthermore, the fixing component includes four sets of connecting blocks mounted on the top surface of the top seat. Each connecting block has a pressure block on its inner side, and bolts are threaded into the internal parts of the connecting blocks. The bolts and pressure blocks are rotatably connected. This design of four sets of connecting blocks, pressure blocks, and bolts allows for convenient fixing of machine feet of different sizes. By rotating the bolts, the tightness of the pressure blocks on the machine feet can be adjusted, ensuring a secure installation. This adjustable fixing method increases the versatility of the device, making it suitable for various types of machinery and improving its practicality.

[0009] Furthermore, a bellows is connected between the piston and the inner top of the inner sleeve, and the bellows is sleeved on the outside of the piston rod. The bellows has good extensibility, and its arrangement can prevent damping oil leakage and ensure the normal operation of the buffer.

[0010] Furthermore, the piston diameter is the same as the inner diameter of the inner sleeve. This ensures that the piston fits tightly within the inner sleeve, allowing the damping oil to flow only through the first and second through holes. This improves the damping effect of the damping oil flow, enhances the vibration reduction performance of the shock absorption device, and ensures that the equipment can more effectively reduce vibration during operation.

[0011] Furthermore, the base, top seat, outer sleeve, inner sleeve, piston, and piston rod are all coaxially arranged. This ensures that the device is subjected to uniform force during operation, avoids additional stress and friction caused by misalignment of components, guarantees that the piston can slide smoothly within the inner sleeve, improves the stability and reliability of the device, extends the service life of the device, and also helps to improve the shock absorption effect.

[0012] Furthermore, the four sets of connecting blocks are evenly installed circumferentially on the top surface of the top seat. The even distribution of the four sets of connecting blocks circumferentially ensures that the mechanical equipment feet are evenly stressed when fixed, preventing the equipment from tilting or shaking due to uneven fixing, further improving the stability of the equipment installation, ensuring the stability of the equipment during operation, and reducing the problem of increased vibration caused by unstable installation.

[0013] Furthermore, the shape of the pressure block is adapted to the shape of the base of the mechanical equipment, and an anti-slip sleeve is fitted on the outside. The anti-slip sleeve on the outside increases the friction between the pressure block and the base of the equipment, preventing the equipment from shifting during operation, and further improving the stability and reliability of the equipment installation.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This vibration damping device for mechanical equipment adopts a parallel design of springs and buffer components. The springs provide basic elastic support, and the buffer components work together to effectively alleviate the impact force during equipment vibration, thus improving the vibration damping effect. Simultaneously, the unique buffer component structure utilizes the flow of damping oil between the first and second through holes to generate damping force, converting the mechanical energy of vibration into heat energy for dissipation. This reduces the vibration amplitude of the equipment, improves its vibration damping performance, and prevents the equipment and the vibration damping device from vibrating together. This effectively reduces the impact of vibration generated during mechanical equipment operation on the equipment itself and the surrounding environment, improves the stability and service life of the equipment, and reduces equipment failures and losses caused by vibration.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4This utility model provides a technical solution: a shock-absorbing device for mechanical equipment, comprising a base 1, a top seat 2 on the top surface of the base 1, a spring 6 and a buffer component connected between the base 1 and the top seat 2, the spring 6 and the buffer component being arranged in parallel, a fixing component on the top surface of the top seat 2 for fixing the feet of the mechanical equipment, and the buffer component including an outer sleeve 7 installed on the top surface of the base 1 and a stopper rod 12 installed on the bottom surface of the top seat 2, an inner sleeve 8 installed on the inner top of the outer sleeve 7, and a piston 11 installed at the bottom end of the stopper rod 12, the piston 11 sliding vertically within the inner sleeve 8, a plurality of first through holes 9 on the bottom surface of the inner sleeve 8, and a plurality of second through holes 10 on the side of the inner sleeve 8 near its top surface, both the outer sleeve 7 and the inner sleeve 8 being filled with damping oil, when the mechanical equipment vibrates, the vibration is transmitted to the top seat 2. The top seat 2 drives the stopper rod 12 and the piston 11 to slide up and down within the inner sleeve 8. When piston 11 slides upward, the damping oil at the bottom of the inner sleeve 8 flows into the outer sleeve 7 through the second through hole 10 and into the inner sleeve 8 through the first through hole 9; when piston 11 slides downward, the damping oil at the top of the inner sleeve 8 flows into the outer sleeve through the first through hole 9 and into the inner sleeve 8 through the second through hole 10. The resistance generated by the damping oil during the flow process forms a damping force, which hinders the movement of piston 11 and converts the mechanical energy of vibration into heat energy, thereby consuming vibration energy. At the same time, spring 6 and buffer absorb part of the vibration energy, playing a buffering role, and together achieve vibration reduction of mechanical equipment.

[0022] In one embodiment of this utility model, the fixing component further includes four sets of connecting blocks 3 installed on the top surface of the top seat 2. Each connecting block 3 has a pressure block 4 on its inner side. Bolts 5 are threadedly engaged with the internal threads of the connecting blocks 3, and the bolts 5 and pressure blocks 4 are rotatably connected. When installing mechanical equipment, the equipment feet are placed between the four sets of pressure blocks 4, and the bolts 5 are rotated. Because the bolts 5 are threadedly engaged with the connecting blocks 3 and rotatably connected to the pressure blocks 4, the rotation of the bolts 5 pushes the pressure blocks 4 towards the equipment feet until the pressure blocks 4 tightly press against the equipment feet, thereby fixing the equipment.

[0023] In one embodiment of this utility model, a bellows 13 is further connected between the piston 11 and the inner top of the inner sleeve 8, and the bellows 13 is sleeved on the outside of the piston rod 12. During the up-and-down sliding of the piston 11 within the inner sleeve 8, the bellows 13 extends and retracts with the movement of the piston 11. When the piston 11 moves upward, the bellows 13 is stretched; when the piston 11 moves downward, the bellows 13 is compressed. Through this expansion and contraction, the bellows 13 always maintains its wrapping around the piston rod 12, effectively preventing damping oil from leaking from the gap between the piston 11 and the inner sleeve 8.

[0024] As an embodiment of this utility model, the diameter of the piston 11 is consistent with the inner diameter of the inner sleeve 8. When the piston 11 slides in the inner sleeve 8, since the diameters of the two are consistent, a relatively sealed space is formed between the piston 11 and the inner sleeve 8. The damping oil cannot leak freely from the gap between the piston 11 and the inner sleeve 8, but can only flow through the first through hole 9 and the second through hole 10 according to the designed path, thereby ensuring the stable generation of damping force.

[0025] As an embodiment of this utility model, the base 1, top seat 2, outer sleeve 7, inner sleeve 8, piston 11, and piston rod 12 are all arranged on the same axis. When the mechanical equipment vibrates, since all components are on the same axis, the vibration transmitted by the top seat 2 can be evenly applied to the piston rod 12 and piston 11. The piston 11 slides more smoothly in the inner sleeve 8, and the flow of damping oil is more stable, thereby ensuring the stable output of damping force and effectively reducing the vibration of the equipment.

[0026] As an embodiment of this utility model, the four sets of connecting blocks 3 are evenly installed on the top surface of the top seat 2 in a circumferential manner. When the connecting blocks 3, pressure blocks 4 and bolts 5 are used to fix the mechanical equipment feet, since the connecting blocks 3 are evenly distributed on the top surface of the top seat 2, each part of the equipment feet can be subjected to uniform pressure, thereby ensuring that the equipment is in a balanced state after fixing and reducing the vibration caused by fixing problems during equipment operation.

[0027] As an embodiment of this utility model, the shape of the pressure block 4 is adapted to the shape of the base of the mechanical equipment, and an anti-slip sleeve is fitted on the outside. The anti-slip sleeve uses the friction of its surface to firmly grip the base of the equipment. Even if the equipment vibrates during operation, it can effectively prevent relative sliding between the base of the equipment and the pressure block 4, thus ensuring the fixation effect of the equipment.

[0028] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.
