Description

Technical Field

[0001] This utility model relates to the field of damping and vibration reduction technology, and in particular to a modular preload adjustable damping and vibration reduction elastic device. Background Technology

[0002] In modern industrial systems, vibration problems in pipelines and equipment can easily lead to mechanical fatigue, noise pollution, and safety hazards. While traditional rigid support structures can limit displacement, they are ineffective at dissipating vibration energy, resulting in insufficient system stability. With the increasing prevalence of precision equipment and long-distance pipelines, the demand for vibration reduction performance is rising. Based on this, products such as damping clamps, vibration dampers, and dampers have emerged. By actively absorbing and converting vibration energy, they significantly reduce the risk of resonance, improve equipment lifespan and operational reliability, and are widely used in energy, chemical, and construction industries.

[0003] Damping vibration reduction devices are typically composed of a composite of elastic materials (such as rubber and polyurethane) and a metal constraint structure. Taking a damping pipe clamp as an example, its inner layer fits the pipe, the outer layer is fixed to the support by bolts, and the middle is filled with a viscoelastic damping layer, which uses the material's shear deformation to convert mechanical energy into heat energy for dissipation. Vibration dampers, on the other hand, use a spring-damping combination structure to buffer impacts and suppress high-frequency vibrations during compression / tension.

[0004] Currently, vibration reduction in pipelines and equipment mainly relies on damping clamps, vibration dampers, and other functional products. These products are complex in structure, relatively expensive, and custom-made. They also have high delivery cycles and costs, and are limited by on-site adjustment limitations. Therefore, a modular, preload-adjustable damping vibration reduction elastic device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a modular preload adjustable damping vibration reduction elastic device, which aims to improve the problems of high product delivery cycle and cost in the prior art, as well as the limitation of on-site adjustment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A modular preload adjustable damping vibration reduction elastic device includes a pipe clamp, a connecting seat is installed on the outside of the pipe clamp, a connecting ring is installed on both sides of the connecting seat, a plurality of locking screws are threaded to the outside of the connecting ring, an elastic element is installed on the inner wall of the locking screw, and a plurality of mounting components are installed on the outside of the connecting ring.

[0008] As a further description of the above technical solution:

[0009] The mounting assembly includes multiple connecting bolts and multiple mounting slots, the multiple mounting slots being disposed on the outside of the connecting ring, and the external threads of the connecting bolts being connected to the inner wall of the mounting slots;

[0010] As a further description of the above technical solution:

[0011] The plurality of locking screws are circumferentially distributed on the outside of the connecting ring;

[0012] As a further description of the above technical solution:

[0013] The plurality of connecting bolts are circumferentially distributed on one side of the connecting ring.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, the preload is adjustable on-site through the cooperation of locking screws and disc-shaped elastic elements. Installation is convenient and requires no complicated tools. The modular design supports quick adaptation to the connection requirements of vibration isolators, dampers, and pipe supports, significantly improving versatility and maintenance efficiency. By adjusting the screw insertion depth, different vibration frequencies and loads can be dynamically matched, taking into account both low-frequency vibration suppression and high-frequency impact attenuation. The elastic element dissipates energy through compression deformation and friction, and the knurled anti-slip mounting groove disperses residual loads, ensuring stability while reducing the risk of material fatigue, thus combining high reliability and economy.

[0023] 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.

[0024] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a modular preload adjustable damping vibration reduction elastic device, including a pipe clamp 2. The pipe clamp 2 adopts a split clamp design. A connecting seat 1 is installed on the outside of the pipe clamp 2. The hollow design of the connecting seat 1 allows through-type installation of the pipe or equipment axis. Connecting rings 3 are installed on both sides of the connecting seat 1. The connecting rings 3 are symmetrically distributed annular bosses with grooves matching the connecting seat 1 on the inner side. They are fixed to both sides of the connecting seat 1 by welding or bolts to form a relay structure for vibration transmission.

[0025] refer to Figures 3 to 5 Multiple locking screws 4 are connected to the external thread of the connecting ring 3. The locking screws 4 are screwed into the threaded holes on the outer edge of the connecting ring 3 in a uniform manner. The screw ends directly press against the elastic element 5. The pre-compression of the elastic element is adjusted by the screwing depth. The multiple locking screws 4 are circumferentially distributed on the outside of the connecting ring 3. The six sets of locking screws 4 are distributed at equal angles along the circumference to form radial pressure application points, ensuring uniform compression deformation of the elastic element 5 and avoiding local stress concentration. The elastic element 5 is installed on the inner wall of the locking screw 4. The elastic element 5 is a multi-layered disc spring or helical spring, nested on the guide post of the inner cavity of the locking screw 4. When the screw is screwed in, it compresses the disc spring to produce axial deformation, and at the same time dissipates vibration energy through the friction interface.

[0026] Multiple mounting components are installed on the outside of the connecting ring 3. The mounting components include multiple connecting bolts 6 and multiple mounting slots. The connecting bolts 6 pass through the slots and connect to the external bracket. The multiple mounting slots are set on the outside of the connecting ring 3 and are symmetrically distributed along the axial direction of the connecting ring 3. The knurling treatment on the inner wall of the slot can increase the friction with the connecting bolts 6 and prevent the bolts from shifting under vibration conditions. The external threads of the connecting bolts 6 are connected to the inner wall of the mounting slots. The multiple connecting bolts 6 are circumferentially distributed on one side of the connecting ring 3. The heads of the connecting bolts 6 are recessed into the mounting slots, and the exposed threaded sections are connected to the external brackets. The circumferential distribution design allows the load to be distributed to the connecting ring 3, avoiding single-point overload.

[0027] Working principle: The pipe or equipment is clamped by the pipe clamp 2. The vibration energy is transmitted to the connecting rings 3 symmetrically distributed on both sides through the connecting seat 1. The locking screws 4 evenly distributed on the outer edge of the connecting ring 3 can be screwed in for adjustment, which compresses the embedded disc-shaped elastic element 5 to produce axial compression deformation, forming an adjustable preload. When the screws 4 are tightened, the multi-layer disc spring or helical spring is compressed, which increases the stiffness of the component, and vice versa. During the transmission of vibration energy, the elastic element 5 dissipates energy through the interlayer friction and nonlinear deformation of the disc spring or helical spring. At the same time, the connecting bolts 6 of the mounting component distribute the residual load to the external support through the knurled anti-slip mounting groove. By adjusting the screw depth of the screws 4, different vibration frequencies and load conditions can be dynamically adapted to achieve full-frequency vibration reduction control from low-frequency resonance suppression to high-frequency impact attenuation.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
