[0002] With the continuous advancement of industrial technology, the operating environment of modern mechanical equipment is becoming increasingly complex. This is especially true in fields such as metallurgy and aerospace, where industrial equipment must operate continuously under high-energy impact loads. In this high-intensity operating environment, the various components of the equipment are often subjected to frequent and severe shock and vibration, resulting in reduced operating accuracy, increased component wear, and even possible equipment failure or malfunction, which in turn affects production efficiency and equipment lifespan.

[0003] Currently, existing vibration reduction devices usually rely on hydraulic buffers or spring elements to mitigate impact and vibration, which generally have the problems of slow response, bulky structure, and easy wear or leakage.

[0004] In addition, most existing unloading and vibration reduction devices can only cope with a single type of vibration or impact, and cannot effectively adjust to multiple vibrations in different directions under different working conditions, resulting in insufficient stability and reliability of the equipment under complex working conditions. Summary of the Invention

[0018] like Figures 1 to 5 As shown, an embodiment of the present invention provides a unloading and vibration reduction device for multi-mechanism equipment, including: a buffer unloading module 1 and a three-dimensional vibration reduction module 2, wherein the buffer unloading module 1 and the three-dimensional vibration reduction module 2 are respectively installed on different vibration surfaces of the multi-mechanism equipment.

[0019] Specifically, the vibration surface connected to the three-dimensional vibration damping module 2, i.e., the second vibration surface, is provided with a threaded hole, the aperture of which corresponds one-to-one to the diameter of the main bolt 201, and the three-dimensional vibration damping module 2 is connected to the second vibration surface through the threaded hole and the main bolt 201.

[0020] Among them, the buffer unloading module has a larger structure and is suitable for multi-mechanism equipment that needs to unload low-frequency strong impact loads.

[0021] Among them, the three-dimensional vibration reduction module structure is relatively small in size and is suitable for multi-mechanism equipment that requires low-frequency vibration reduction.

[0022] It should be noted that the buffer unloading module and the three-dimensional vibration reduction module are installed separately on different vibration surfaces of multi-mechanism equipment. The buffer unloading module is larger and suitable for unloading low-frequency, high-impact loads, while the three-dimensional vibration reduction module is smaller and suitable for reducing low-frequency vibrations. This design separates the functions of the two modules, achieving more targeted vibration control, effectively absorbing impact energy and attenuating small vibrations respectively. Furthermore, the three-dimensional vibration reduction module is connected to the main bolts via threaded holes, ensuring a stable installation and further optimizing the overall performance and stability of the equipment.

[0023] Optionally, the unloading and vibration reduction device includes: two buffer unloading modules 1 and a three-dimensional vibration reduction module 2 that are identically arranged and symmetrically arranged in parallel, wherein each buffer unloading module 1 is integrally connected via an impact force-bearing member 101 .

[0024] It should be noted that the unloading and vibration reduction device is configured by setting up two identically arranged and symmetrically parallel buffer unloading modules and three-dimensional vibration reduction modules. Each buffer unloading module is connected as a whole through an impact force-bearing member, so that the impact load can be dispersed to the two modules, reducing the force burden of a single module and improving the overall unloading and vibration reduction efficiency.

[0025] The buffer unloading module 1 includes: an impact force-bearing member 101, a first connecting member 102, a rubber spring 103, a second connecting member 104, a mass block 105 and a guide rail 106, wherein the impact force-bearing member 101, the first connecting member 102, the rubber spring 103, the second connecting member 104 and the mass block 105 are connected in sequence in a first direction, and the mass block 105 can be slidably installed on the guide rail 106.

[0026] It should be noted that by sequentially connecting the impact-bearing member, connector, rubber spring, and mass, and arranging the mass to slide on the guide rail, the impact energy is absorbed and dissipated step by step along the first direction. The rubber spring provides primary cushioning, while the sliding mass provides secondary limiting energy absorption, effectively reducing the impact peak and vibration amplitude. This improves the stability and reliability of the multi-mechanism equipment under strong impact conditions and extends its service life.

[0027] In a possible embodiment, the buffer unloading module 1 further includes a plurality of first bolts 107 , the first connecting member 102 is fixed to the threaded hole of the impact force member 101 through the first bolts 107 , and the second connecting member 104 is fixed to the threaded hole of the mass block 105 through the first bolts 107 .

[0028] It should be noted that fixing the first connecting member and the second connecting member to the impact-bearing member and the mass block respectively by multiple first bolts not only effectively disperses the impact load and improves the connection strength and stability, but also significantly enhances the fatigue resistance of the unloading module in a high-frequency impact environment, thereby improving the operating reliability and service life of the multi-mechanism equipment.

[0029] Optionally, a trapezoidal groove is provided at the bottom of the mass block 105 , and the mass block 105 is slidably mounted on the guide rail 106 through the trapezoidal groove.

[0030] Specifically, the bottom of mass block 105 is provided with a trapezoidal groove, through which mass block 105 is slidably mounted on guide rail 106. When rubber spring 103 is subjected to an impact load, mass block 105 can slide back and forth along guide rail 106, thereby providing a position limit and buffering function. Furthermore, the total mass of mass block 105 can be adjusted based on the mass of impact-bearing member 101.

[0031] It should be noted that by providing a trapezoidal groove at the bottom of the mass block and connecting it to the guide rail in a sliding manner, when subjected to an impact load, the mass block slides along the guide rail to absorb energy, effectively slowing the transmission rate of the impact force, reducing the impact peak, and preventing the rigidity of the equipment from being damaged. Furthermore, by adjusting the total mass of the mass block, precise matching and adaptive adjustment of the unloading vibration frequency are achieved, significantly improving the responsiveness and reliability of multi-mechanism equipment to shock environments of varying intensities, and possessing excellent engineering application value.

[0032] The three-dimensional vibration reduction module 2 includes: a main bolt 201, an iron block shell 202, a rubber block 203 and a self-locking gasket 204, wherein the rubber block 203 and the self-locking gasket 204 are connected in sequence with the main bolt 201 as the axis in the second direction, and the rubber block 203 is arranged inside the iron block shell 202 to solve the vibration problem in the vertical direction.

[0033] It should be noted that the main bolts penetrate the rubber block and form an integrated connection with the self-locking gasket. The rubber block is located inside the iron block shell, forming a highly efficient vibration absorption and dissipation mechanism in three dimensions. This structure not only improves the absorption efficiency of vibration energy and avoids the problem of rubber block failure or dislocation due to vibration, but also provides anti-loosening protection for the bolt connection through the self-locking gasket, significantly improving the long-term stability and service life of multi-mechanism equipment in complex impact environments.

[0034] Optionally, the iron block shell 202 has various shapes.

[0035] Specifically, according to the vibration characteristics and installation space requirements in different actual application environments, the iron block shell 202 of the three-dimensional vibration reduction module 2 can adopt various shapes, and the shape adjustment can be modified according to the specific installation method implemented.

[0036] It should be noted that by freely adjusting the shape of the iron block shell according to different application environments, the present invention improves the performance adaptability, installation flexibility and vibration control accuracy of multi-mechanism equipment under various complex vibration conditions, and significantly enhances the breadth and depth of engineering applications of multi-mechanism equipment.

[0037] Furthermore, the shape of the rubber block 203 may be adjusted accordingly according to the different vibration frequencies, vibration directions, installation spaces, and vibration absorption performance requirements in different actual application environments.

[0038] Optionally, the rubber block 203 is configured to be in a stepped shape.

[0039] Specifically, the rubber block 203 is configured in a stepped shape so as to effectively avoid direct contact between the iron block shell 202 and the main bolt 201 during the vibration absorption process.

[0040] It should be noted that the stepped rubber block design allows it to absorb vibration energy in stages during the vibration absorption process, effectively avoiding direct contact and impact between the iron block shell and the main bolt, preventing damage to the connection caused by hard collisions. This design improves the energy dissipation efficiency, structural stability, and service life of the three-dimensional vibration damping module in complex vibration environments, and enhances the adaptability of multi-mechanism equipment to multiple working conditions and the engineering application flexibility.

[0041] In a possible implementation, the three-dimensional vibration reduction module 2 further includes a main nut 205 , a plurality of second bolts 206 , and a plurality of sub-nuts 207 , wherein the diameters of the second bolts 206 correspond one-to-one to the apertures of the sub-nuts 207 .

[0042] It should be noted that by adding a main nut, multiple second bolts and sub-nuts in the three-dimensional vibration damping module and keeping the apertures of the two corresponding one to one, a multi-point force and uniform tightening structure is formed, which effectively enhances the strength and stability of the internal connection of the module, and improves the durability and anti-loosening ability of the module in frequent impact and multi-directional vibration environments. At the same time, it facilitates modular disassembly and subsequent maintenance, and significantly improves the engineering application reliability and service life of multi-mechanism equipment.

[0043] Furthermore, the main nut 205 is disposed between the rubber block 203 and the self-locking washer 204 .

[0044] Specifically, the main nut 205 is used in conjunction with the self-locking gasket 204 to tighten the connection between the main bolt 201 and the second vibration surface to prevent the main bolt 201 from loosening or falling off during operation. At the same time, the rubber block 203 is pressed and fixed by the main nut 205 to limit the axial sliding of the rubber block 203 on the main bolt 201.

[0045] It should be noted that the combination of a main nut and a self-locking washer ensures a secure connection between the main bolt and the secondary vibration surface, preventing the bolt from loosening or falling out due to vibration. Furthermore, the main nut compresses the rubber block, preventing axial slippage during impact or vibration, ensuring the continuity and stability of the vibration reduction effect. This design improves the durability and reliability of the vibration reduction module in high-vibration environments, significantly reducing maintenance requirements and operating costs for multi-mechanism equipment.

[0046] Furthermore, the iron block shell 202 includes an upper iron block shell and a lower iron block shell with a boss, and the rubber block 203 is arranged between the upper iron block shell and the lower iron block shell, wherein the threaded hole of the boss of the upper iron block shell and the threaded hole of the boss of the lower iron block shell are symmetrically arranged.

[0047] Specifically, the iron block shell 202 includes an upper iron block shell and a lower iron block shell with bosses, and the rubber block 203 is arranged between the upper iron block shell and the lower iron block shell, so that the rubber block 203 is covered and limited, effectively limiting its position movement.

[0048] It should be noted that by providing bosses on the upper and lower portions of the iron shell 202 and sandwiching the rubber block 203 between them, the rubber block is prevented from shifting during vibration, ensuring effective vibration absorption. Furthermore, the symmetrical design of the threaded holes enhances the stability of the overall connection, preventing loosening or failure due to vibration or impact. This design optimizes the performance of the vibration damping module, increases the reliability and longevity of multi-mechanism equipment, and simplifies assembly and maintenance.

[0049] Furthermore, the second bolt 206 is connected to the sub-nut 207 through the threaded hole of the boss of the upper iron block shell and the threaded hole of the boss of the lower iron block shell.

[0050] It should be noted that the second bolt penetrates the bosses of the upper and lower iron block shells and is connected and fixed by a sub-nut, forming a high-strength integral lock for the internal structure of the vibration damping module. This design not only enhances the stability and rigidity of the module's internal connections, but also effectively improves the rubber block's compression and vibration energy absorption capacity. At the same time, the multi-point decentralized connection design improves the module's fatigue life and dynamic balance under high-frequency vibration and impact conditions, and facilitates modular disassembly and maintenance, significantly improving the engineering application reliability and service life of multi-mechanism equipment.

[0051] The first direction and the second direction are collinear.

[0052] The impact direction of the multi-mechanism device is perpendicular to the impact force member 101 and the self-locking gasket 204, and the vertical vibration direction of the multi-mechanism device is parallel to the impact force member 101 and the self-locking gasket 204, wherein the impact direction is parallel to the first direction, and the vertical vibration direction is perpendicular to the second direction.

[0053] It should be noted that the impact direction refers to the direction of sudden forces acting on multi-mechanism equipment during operation (e.g., impact, inertial force at startup, etc.). The vertical vibration direction refers to the slight vertical displacement or vibration of the equipment caused by mechanical vibration during operation, repeated effects of gravity, or transmission from the ground.

[0054] It should be noted that the buffer unloading module and the three-dimensional vibration reduction module are collinearly arranged along the same axis to process the impact energy and vibration energy simultaneously, thereby improving the energy dissipation efficiency. The impact energy and vibration energy are continuously processed on the same path, thereby improving the energy dissipation efficiency. At the same time, the impact direction of the multi-mechanism equipment is set to be perpendicular to the installation direction of the impact force-bearing member and the self-locking gasket, and the vertical vibration direction of the multi-mechanism equipment is set to be parallel to the installation direction of the impact force-bearing member and the self-locking gasket, thereby achieving effective decoupling of the impact unloading and vibration reduction processes, reducing lateral shaking, improving the dynamic response stability of the multi-mechanism equipment and the fatigue resistance of the connection structure, significantly extending the service life of the module, and improving the overall operational reliability of the equipment.

[0055] When a multi-mechanism device generates a vibration signal, the vibration signal is unloaded and buffered by the buffer unloading module 1 and the three-dimensional vibration reduction module 2 respectively.

[0056] In summary, the unloading and vibration reduction device for multi-mechanism equipment designed in the present invention effectively controls low-frequency strong impact loads and low-frequency vibrations respectively through the reasonable configuration of the buffer unloading module and the three-dimensional vibration reduction module. The buffer unloading module absorbs strong impact energy through a large-volume design and a sliding mass block, reduces the impact peak, and enhances the stability of the equipment. The three-dimensional vibration reduction module achieves efficient absorption of low-frequency vibrations through a small-volume design and flexible shape adjustment. The combination of the two can independently and efficiently process different types of vibration signals in multi-mechanism equipment, reduce the workload of a single module, and improve the overall vibration reduction effect and equipment reliability. At the same time, the symmetrical parallel arrangement between the modules optimizes the force distribution of the modules, enhances the durability and stability of the equipment, and extends the service life of the equipment, with significant engineering application value.

[0057] The beneficial effects brought about by the technical solution provided by the embodiment of the present invention include at least: In the present invention, an impact force-bearing member, a first connecting member, a rubber spring, a second connecting member and a mass block are connected in sequence in the first direction, and the mass block is slidably installed on the guide rail. A main bolt, an iron block shell, a rubber block and a self-locking gasket are used. The rubber block and the self-locking gasket are connected in sequence in the second direction with the main bolt as the axis. The rubber block is arranged inside the iron block shell. It no longer relies on hydraulic buffers or spring elements to reduce impact and vibration. It has a faster response, a lighter structure, is not prone to wear or leakage, can cope with various types of vibrations or impacts, and can effectively adjust multiple vibrations in different directions under different working conditions, thereby improving the stability and reliability of the equipment under complex working conditions.

[0058] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. While specific details are described in detail in the preferred embodiments to provide a thorough understanding of the present invention, those skilled in the art will be able to fully understand the present invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
