Description

Technical Field

[0001] This utility model relates to the field of vibration control device technology, and in particular to a modular splicing spring damping integrated vibration control device. Background Technology

[0002] Spring-damped integrated vibration control devices are commonly used components in mechanical engineering, construction, bridge building, and precision instrument fields to achieve vibration isolation and buffering. They provide elastic support through springs and dissipate vibration energy through dampers, thereby protecting equipment or structures from vibration damage.

[0003] However, in practical applications, different equipment or different working conditions have different requirements for the load-bearing capacity and vibration isolation performance of vibration control devices. Traditional vibration control devices are usually integral structures with fixed specifications, which limits their applicability and makes it difficult to flexibly adapt to various needs. When the required load-bearing capacity is large or the installation area is irregular, a single specification device often cannot meet the usage requirements.

[0004] To address the aforementioned issues, existing technologies have developed solutions that combine multiple independent vibration damping units to improve overall load-bearing capacity and adapt to different site layouts. However, existing splicing methods generally suffer from structural defects. On the one hand, many spliced ​​structures rely solely on simple bolt connections or frame constraints, resulting in insufficient reliability and rigidity of the connections. When subjected to complex vibration loads, the connection points are prone to loosening or misalignment, thereby affecting the overall vibration isolation effect and structural stability.

[0005] On the other hand, some splicing devices adopt complex fixing structures in order to pursue connection strength, which makes the installation and disassembly process extremely cumbersome. When an independent vibration damping unit needs to be repaired or replaced due to fatigue or damage, it is often necessary to disassemble a large area of ​​the splicing platform. The operation is difficult, time-consuming and labor-intensive. In some cases, the damage of a single unit may even lead to the scrapping of the entire splicing platform, which greatly increases the cost of use and maintenance.

[0006] Therefore, this utility model proposes a modular splicing spring damping integrated vibration control device to overcome the shortcomings of the prior art. Utility Model Content

[0025] To solve the aforementioned technical problems, the core of the technical solution in this embodiment lies in the specific structural fit and connection relationship formed between the connecting assembly composed of the fixing plate 5, the connecting plate 10, the fixing bolt 7, and the fixing nut 8, and the slots 13 and connecting grooves 15 on the bottom plate 1 and the top plate 2. Please refer to the following carefully.

At the same time, the connecting blocks 12 on both sides of the connecting plate 10 are locked into the connecting grooves 15 opened inside the placement grooves 14 on the adjacent bottom plate 1 or top plate 2. After the locking block 9 and the connecting block 12 are positioned, the two fixing bolts 7 are respectively passed through the two connecting holes 1-6 on the fixing plate 5, and the fixing bolts 7 are further passed through the connecting holes 2-11 on the connecting plate 10 corresponding to the two connecting holes 1-6. Finally, a fixing nut 8 is threaded onto the bottom end of each fixing bolt 7.

The buffer spring 4 and the damper 3 are coaxially arranged, and the two ends of the buffer spring 4 abut against the bottom plate 1 and the top plate 2 respectively. The two ends of the damper 3 are also fixedly connected to the bottom plate 1 and the top plate 2 respectively, thus forming a compact integrated spring damping unit.

[0026] As a preferred embodiment, please refer to Figure 2 The slots 13 are provided on the surfaces of the base plate 1 and the top plate 2 near the four corners. Specifically, slots 13 are provided at the four corners of the base plate 1 and the four corners of the top plate 2 to fix the insertion and positioning of the plate 5 and achieve initial alignment during splicing.

[0027] As a preferred embodiment, please refer to Figure 2 The placement groove 14 is provided on the four sides of the bottom plate 1 and the top plate 2, and the connecting groove 15 is provided inside the placement groove 14. The placement groove 14 provides clearance space for the installation of the connecting plate 10, and the connecting groove 15 is used to achieve a snap-fit ​​engagement with the connecting block 12 on the connecting plate 10.

[0028] As a preferred embodiment, please refer to Figure 3 The locking block 9 is fixed to the bottom end of the fixing plate 5. The cross-sectional shape of the locking block 9 is adapted to the internal contour of the slot 13 so that it can be detachably slid into the slot 13 along the depth direction.

[0029] As a preferred embodiment, please refer to Figure 3 The connecting block 12 is fixed on both sides of the connecting plate 10. The connecting block 12 is preferably a rectangular block structure, which is used to snap into the connecting groove 15 to realize the horizontal positioning of the connecting plate 10.

[0030] As a preferred embodiment, please refer to Figure 3 Two connecting holes 6 are symmetrically provided in the middle of the fixing plate 5. The two connecting holes 6 are spaced apart along the length of the fixing plate 5 and are used to pass through the fixing bolts 7.

[0031] As a preferred embodiment, please refer to Figure 3 The connecting plate 10 has a second connecting hole 11 in the middle. The number and position of the second connecting hole 11 correspond to the two first connecting holes 6 to ensure that the fixing bolt 7 can pass smoothly through the fixing plate 5 and the connecting plate 10.

[0032] As a preferred embodiment, please refer to Figure 3 There are two fixing bolts 7. The two fixing bolts 7 pass through the two connecting holes 1 6 and the corresponding connecting holes 2 11 respectively. The fixing nut 8 is threaded to the bottom of each fixing bolt 7. The fixing plate 5 and the connecting plate 10 are tightened by tightening the fixing nut 8.

[0033] Working principle: When it is necessary to control the vibration of the equipment or to splice multiple vibration control units to form a large vibration isolation platform, the operator first places the base plate 1 in the predetermined position. The damper 3 and the buffer spring 4 are fixedly installed between the base plate 1 and the top plate 2. The buffer spring 4 is preferably sleeved on the outer surface of the damper 3. The buffer spring 4 and the damper 3 work together to absorb and dissipate vibration energy. When it is necessary to combine two or more modular splicing spring damping integrated vibration control devices, the operator aligns the bottom plate 1 or top plate 2 of the two units side by side. At this time, the operator takes the fixing plate 5 and aligns the locking block 9 fixed at the bottom of the fixing plate 5 with the locking slot 13 opened near the four corners on the surface of the bottom plate 1 or top plate 2 of the unit. The locking block 9 is detachably slidably inserted into the locking slot 13. This sliding insertion cooperation between the locking block 9 and the locking slot 13 provides the fixing plate 5 with a stable vertical positioning and preliminary horizontal limit. At the same time, the operator takes the connecting plate 10, aligns the connecting blocks 12 fixed on both sides of the connecting plate 10 with the placement slots 14 opened on the four sides of the bottom plate 1 or top plate 2 of the adjacent unit, and makes the connecting blocks 12 snap into the connecting slots 15 opened inside the placement slots 14. The snap-fit ​​between the connecting blocks 12 and the connecting slots 15 provides accurate installation positioning for the connecting plate 10. After the fixing plate 5 and the connecting plate 10 are positioned with the slots 13 and connecting slots 15 of the two units respectively by the locking block 9 and the connecting block 12, the operator takes two fixing bolts 7 and passes them through the two symmetrical connecting holes 6 in the middle of the fixing plate 5. After the shank of the fixing bolt 7 passes through the connecting hole 6, it continues to pass through the connecting hole 11 in the middle of the connecting plate 10, which corresponds to the two connecting holes 6. After both fixing bolts 7 have completely passed through the connecting holes 6 and 11, the operator threaded a fixing nut 8 onto the bottom end of each fixing bolt 7 exposed below the connecting plate 10. Finally, the operator uses tools to tighten each fixing nut 8. During the tightening process, the fixing nut 8 applies an axial preload to the fixing bolt 7. This tension is transmitted through the head of the fixing bolt 7 and the fixing nut 8, and then acts in the opposite direction on the fixing plate 5 and the connecting plate 10, thereby firmly clamping and fixing the fixing plate 5 and the connecting plate 10 together. Through the rigid connection of the fixing plate 5 and the connecting plate 10, as well as the limiting fit between the locking block 9 and the locking groove 13, and the locking fit between the connecting block 12 and the connecting groove 15, this utility model solves the problem of unstable splicing structure and easy loosening in the prior art, and realizes a high-strength and high-reliability mechanical connection between modular units, ensuring the overall rigidity and stability after splicing. When the equipment equipped with this utility model starts to operate and generates vibration, or when external environmental vibration is transmitted to the base plate 1, a vertical relative displacement will occur between the base plate 1 and the top plate 2. This relative displacement will cause the buffer spring 4 sleeved on the outer surface of the damper 3 to be compressed or stretched. The buffer spring 4, as an elastic element, is used to store vibration energy and provide restoring force, thereby changing the vibration characteristics of the system. As the buffer spring 4 deforms, the damper 3, which is fixed at both ends to the bottom plate 1 and the top plate 2 respectively, also moves relative to each other. During the relative movement, the internal damping structure of the damper 3 generates damping force through the flow or friction of the internal medium. This damping force irreversibly converts the vibration energy into heat energy and dissipates it. Through the synergistic effect of the elastic energy storage of the buffer spring 4 and the energy dissipation of the damper 3, this utility model achieves effective control and attenuation of vibration. When multiple units are spliced ​​together, the robust connection structure ensures that the base plate 1 and top plate 2 of all units can form a cohesive platform to absorb and attenuate vibration loads. Furthermore, when the damper 3 or buffer spring 4 of a certain unit fails, the operator only needs to reverse the operation, loosen the fixing nut 8, pull out the fixing bolt 7, and remove the fixing plate 5 and connecting plate 10 to easily disassemble, repair, or replace the individual unit without having to scrap the entire unit.
