Description

Technical Field

[0001] This utility model relates to the field of energy dissipation and vibration reduction structure technology, specifically to a flexible tube clamp type composite damper connector with good vibration reduction performance. Background Technology

[0002] Dampers are widely used for vibration reduction and noise control in various industrial fields such as construction engineering and mechanical engineering. In vibration and noise control, the specific structural design of the damper body is generally used to meet the requirements, often overlooking the fact that the damper connector itself can also contribute to vibration and noise reduction. Early methods often involved direct welding of steel plates or using simple steel supports to connect the damper to the engineering structure. However, with the development of damper connector technology, the development of specialized damper connectors (such as cleat type, flange type, hinged type, etc.) tailored to different application areas, types of dampers, and load characteristics has become a research hotspot in vibration and noise control using dampers in construction engineering and mechanical engineering.

[0003] Existing damper connectors are mostly simple in structure and have limited performance. They can only limit the radial sway of the engineering structure, but cannot provide radial support stiffness to protect the internal pins. This results in poor fatigue resistance and severely limits the service life of the damper connector. Therefore, this invention proposes a flexible pipe clamp type composite damper connector with good vibration reduction performance to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a flexible pipe clamp type composite damper connector with good vibration reduction performance. The elastic element can provide a certain degree of axial preload to the pin, and within a certain load deformation range, it can restore the pin to the center position of the circular cavity inside the connector, reducing or eliminating the slight displacement of the pin relative to the connector caused by the load, avoiding the additional bending moment caused by the pin deformation constraint, and playing a structural deformation compensation role to reduce the fretting wear of the pin and extend the fatigue life. Under instantaneous impact loads (such as pipe system damage or equipment emergency stop), the elastic element deforms to absorb part of the vibration energy, and the preload of the elastic element on the pin makes the contact pressure between the pin and the inner wall of the circular cavity of the connector more uniform, reducing or eliminating the hidden danger of excessive local stress peak caused by the local edge contact between the pin and the connector, thereby reducing the risk of damage to the pin and the connector due to excessive peak load. The overall structure is ingeniously and reasonably designed, easy to install, and has excellent vibration reduction effect. It can be applied to the connection and anchoring positions of hydraulic dampers, pipeline supports, etc.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a flexible tube clamp type composite damper connector with good vibration reduction performance, including a seat body and a pin. The seat body has a circular cavity that extends through the left and right end faces. The pin passes through the inside of the circular cavity and is clearance-fitted with the inner wall surface of the circular cavity. The two ends of the pin extend to the outside of the circular cavity, and the two ends of the pin are equipped with clamping components for axially limiting and clamping them onto the seat body. Several elastic elements capable of radial expansion and contraction are arranged circumferentially between the inner peripheral wall surface of the circular cavity and the outer peripheral wall surface of the pin.

[0006] This utility model discloses a flexible pipe clamp type composite damper connector with good vibration reduction performance. The elastic element can provide a certain degree of axial preload to the pin, which can restore the pin to the center position of the circular cavity inside the connector within a certain load deformation range. This reduces or eliminates the slight displacement of the pin relative to the connector caused by the load, avoids the additional bending moment caused by the pin deformation constraint, and plays a role in structural deformation compensation to reduce the fretting wear of the pin and extend its fatigue life. Under instantaneous impact loads (such as pipe system damage or equipment emergency stop), the elastic element deforms to absorb part of the vibration energy. Furthermore, the preload provided by the elastic element to the pin makes the contact pressure between the pin and the inner wall of the circular cavity of the connector more uniform, reducing or eliminating the hidden danger of excessive local stress peak caused by local edge contact between the pin and the connector, thereby reducing the risk of damage to the pin and the connector due to excessive peak load. The overall structure is ingeniously and reasonably designed, easy to install, and has excellent vibration reduction effect. It can be applied to the connection and anchoring positions of hydraulic dampers, pipeline supports, etc.

[0007] The preferred technical solution is that the seat body includes a seat body one and a seat body two. The lower end face of the seat body has an arc-shaped groove one that runs through both the left and right ends. The inner wall of the arc-shaped groove one has a plurality of blind holes one that are radially spaced apart. The lower end of the seat body also has an ear plate one that extends forward and backward. The upper end face of the seat body two has an arc-shaped groove two that runs through both the left and right ends. The inner wall of the arc-shaped groove two has a plurality of blind holes two that are radially spaced apart. The upper end of the seat body two also has an ear plate two that extends forward and backward. The ear plate one and the ear plate two have corresponding mounting holes one. The seat body one and the seat body two are fixedly connected together by bolt assemblies that pass through the mounting holes one on the two sets of corresponding ear plates one and ear plates two on the front and rear sides. The elastic element is embedded in both the blind hole one and the blind hole two. The base is formed by connecting base one and base two with corresponding bolts. The elastic element is conveniently installed inside blind hole one on base one or blind hole two on base two, ensuring that the elastic tube clamp type composite damper connection base with good vibration reduction performance of this utility model can be assembled and implemented smoothly and quickly.

[0008] A further preferred technical solution includes a blind groove 1 with an opening facing outward at the upper end of the first seat body, with a cover plate 1 installed at the port of the blind groove 1; and a blind groove 2 with an opening facing outward at the lower end of the second seat body, with a cover plate 2 installed at the port of the blind groove 2. Both blind groove 1 and blind groove 2 are filled with damping particles. The damping particles collide and rub against each other under vibration excitation, converting the mechanical energy of the vibration into heat energy for dissipation. This energy dissipation mechanism is particularly effective for mid-to-high frequency vibrations (hundreds of Hz to thousands of Hz), compensating for the insufficient attenuation of traditional dampers (such as viscous dampers) in the mid-to-high frequency range. Furthermore, the main control frequency band can be adjusted by changing parameters such as the material, particle size, and filling amount of the damping particles. In certain application scenarios, the elastic tube clamp type composite damper connector of this invention can be used directly as a damper without the need for an additional damper, significantly saving installation space, especially suitable for space-constrained scenarios, while also reducing the added mass of the engineering structure.

[0009] A further preferred technical solution is that the blind groove has a countersunk groove at one end, and the vertical bottom surface of the countersunk groove and the outer periphery of the cover plate are provided with corresponding mounting holes. The cover plate is embedded in the countersunk groove and is fixedly connected together by screws passing through the corresponding mounting holes.

[0010] The blind groove has a countersunk groove at its second port, and corresponding mounting holes are formed on the bottom surface of the countersunk groove and the outer periphery of the cover plate. The cover plate is embedded in the countersunk groove and fixed together by screws passing through the corresponding mounting holes. The cover plate is simply fixed in the countersunk groove, has good sealing performance, and is easy to remove to adjust the parameters of the damping particles, making it highly feasible for application.

[0011] A further preferred technical solution is that the lower end face of the second seat is an arc-shaped convex structure, the second blind groove and the second countersunk groove are both formed on the arc-shaped convex structure, and the second cover plate is an arc-shaped plate.

[0012] A further preferred technical solution is that the seat includes two seats corresponding to the left and right ends of the pin, and the two seats are fixedly connected together at intervals by a connecting plate located between them. The two seats are designed to extend the axial length of the damper connecting seat, thereby better excitation of the wide frequency range of the vibration spectrum; on the other hand, the manufacturing feasibility is good, ensuring that the damper connecting seat of this utility model can be successfully manufactured and implemented, and it is also highly portable.

[0013] A further preferred technical solution is that the connecting plate is vertically welded and fixed to the two adjacent inner end faces of the two seat bodies, or the connecting plate is vertically welded and fixed to the two adjacent inner end faces of the two seat bodies. The vertical welding of the connecting plate to the two adjacent inner end faces of the two seat bodies or the two seat bodies allows the seat bodies to also provide axial stiffness limiting for the engineering structure, reducing the load on the pins to a certain extent and helping to extend the service life of the damper connecting seat of this utility model.

[0014] A further preferred technical solution is that the opening of the blind groove one on one of the seats faces away from the other seat, and spacers fitted onto the pins are fixed at the adjacent ends of the circular cavities inside the two seats, with the spacers and the pins having a clearance fit. The opening direction of the blind groove one is reasonable, making it easy to remove the cover plate one to replace the adjustable damping particles.

[0015] A further preferred technical solution is that corresponding mounting holes four are provided on the two adjacent inner end faces of the two seat bodies and the corresponding spacer rings. The spacer rings are fixedly installed on the inner end faces of the seat bodies by screws passing through the mounting holes four. The spacer rings seal the inner ends of the circular cavities on the two seat bodies, thereby effectively preventing dust and other contaminants from entering the circular cavities inside the seat bodies, which helps to ensure the good durability and performance of the damper connecting seat of this utility model.

[0016] A further preferred technical solution includes annular grooves on the outer peripheral surfaces of both ends of the pin. A retaining ring is engaged within each annular groove to limit the washer fitted onto the pin end and abut against the corresponding outer end face of the seat. The annular groove, washer, and retaining ring located at the same end of the pin constitute a set of the engagement assembly. The engagement assembly has a simple structural design, high feasibility of application, and ensures that the pin and seat can be smoothly and quickly assembled into the damper connecting seat of this utility model.

[0017] The advantages and beneficial effects of this utility model are as follows:

Within a certain load deformation range, it can restore the pin shaft to the center position of the circular cavity inside the connector body, reducing or eliminating the slight displacement of the pin shaft relative to the connector body caused by the load, avoiding the additional bending moment caused by the pin shaft deformation constraint, and playing a structural deformation compensation role to reduce the fretting wear of the pin shaft and extend its fatigue life. Under instantaneous impact loads (such as pipe system damage or equipment emergency stop), the elastic element elastically deforms to absorb part of the vibration energy. Furthermore, the preload effect of the elastic element on the pin shaft makes the contact pressure between the pin shaft and the inner wall of the circular cavity of the connector body more uniform, reducing or eliminating the hidden danger of excessive local stress peak caused by the local edge contact between the pin shaft and the connector body, thereby reducing the risk of damage to the pin shaft and the connector body due to excessive peak load. The overall structure is ingeniously and reasonably designed, easy to install, and has excellent vibration reduction effect. It can be applied to the connection and anchoring positions of hydraulic dampers, pipeline supports, etc.

The lower end of the second seat has a blind groove with an opening facing outwards, and a cover plate is installed at the port of the blind groove. Both blind grooves are filled with damping particles. The damping particles collide and rub against each other under vibration excitation, converting the mechanical energy of the vibration into heat energy for dissipation. This energy dissipation mechanism is particularly effective for mid-to-high frequency vibrations (hundreds of Hz to thousands of Hz), compensating for the insufficient attenuation of traditional dampers (such as viscous dampers) in the mid-to-high frequency range.
