Description

Technical Field

[0001] The utility model relates to the technical field of composite dampers, in particular to a high-ductility composite damper. Background Art

[0002] High-ductility composite damper is a device that can effectively absorb and dissipate structural vibration energy. It is widely used in earthquake engineering, building structure shock absorption, mechanical equipment vibration prevention and other fields. Its main principle is to use the friction, shear, plastic deformation and other effects generated by the internal filling material (such as high-ductility metal, viscoelastic material, etc.) during the stress deformation process to consume the external input vibration energy, thereby achieving the purpose of shock absorption and protection of the main structure. In terms of specific structure, the high-ductility composite damper may include two parts: one is the main structure, which is usually made of high-strength steel with high load-bearing capacity and good ductility; the other is the damping medium, such as nonlinear viscoelastic damping material or specially designed friction components.

[0003] The advantage of this damper is that it can maintain a stable damping effect under large deformation. It is particularly suitable for vibration control under extreme load conditions. It is of great significance for improving the seismic performance of building structures and protecting people’s lives and property.

[0004] However, when the damper is suddenly subjected to a large impact force, the specific structure inside the damper needs to be simply protected to ensure the durability of the damper. Therefore, it is necessary to propose a high-ductility composite damper. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a high-ductility composite damper.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A high-ductility composite damper comprises a damper main cavity, wherein an upper fixed baffle and a lower fixed baffle are fixedly installed in the damper main cavity, wherein the upper fixed baffle is arranged above the lower fixed baffle, and wherein the upper fixed baffle and the lower fixed baffle divide the interior of the damper main cavity into a spring cavity, a rubber cavity and a magnet cavity, wherein the spring cavity, the rubber cavity and the magnet cavity are arranged in sequence from top to bottom, wherein a sliding column is slidably arranged in the damper main cavity, wherein the sliding column slides through the top end of the damper main cavity, and wherein fixed mounting plates are fixedly installed at the bottom end of the damper main cavity and the top end of the sliding column.

[0008] Preferably, a first pressing plate, a second pressing plate and a third pressing plate are fixedly mounted on the sliding column, the first pressing plate, the second pressing plate and the third pressing plate are arranged in sequence from top to bottom, the first pressing plate is movably arranged in the spring cavity, the second pressing plate is movably arranged in the rubber cavity, and the third pressing plate is movably arranged in the magnet cavity;

[0009] Preferably, a functional spring is sleeved on the sliding column, and the functional spring is elastically connected between the bottom end of the first pressing plate and the top end of the upper fixed partition;

[0010] Used to absorb external impact force on the device. When the device is subjected to external impact force, the sliding column moves downward, thereby causing the first pressure plate to move in the spring cavity. The first pressure plate compresses the functional spring, so that the external impact force is absorbed under the reaction force of the functional spring.

[0011] Preferably, a first energy-absorbing rubber ring is fixedly installed at the bottom end of the second pressing plate, and a second energy-absorbing rubber ring is fixedly installed at the top end of the lower fixed partition;

[0012] It is used to absorb the external impact force exerted on the device. When the device is subjected to the external impact force, the sliding column moves downward, thereby causing the second pressure plate to move in the rubber cavity. The second pressure plate drives the first energy-absorbing rubber ring to move downward, causing the first energy-absorbing rubber ring and the second energy-absorbing rubber ring to contact and be compressed. As the first energy-absorbing rubber ring and the second energy-absorbing rubber ring are compressed, the external impact force is absorbed.

[0013] Preferably, a first fixed magnet is fixedly installed at the bottom end of the third pressure plate, a second fixed magnet is fixedly installed at the bottom end of the damper main cavity, the first fixed magnet and the second fixed magnet repel each other, and anti-collision rubber pads are fixedly installed at the bottom end of the first fixed magnet and the top end of the second fixed magnet;

[0014] It is used to absorb the external impact force exerted on the device. When the device is subjected to the external impact force, the sliding column moves downward, thereby causing the third pressure plate to move in the magnet cavity. The third pressure plate drives the first fixed magnet to move downward, causing the first fixed magnet and the second fixed magnet to approach each other, and absorb the external impact force under the action of the mutually repelling magnetic fields of the two.

[0015] The four corners of the fixed installation plate are all provided with installation holes.

[0016] The utility model has the following beneficial effects:

[0017] 1. By setting a functional spring, when the device is subjected to external impact force, the sliding column moves downward, thereby causing the first pressure plate to move in the spring cavity. The first pressure plate compresses the functional spring, so that the external impact force is absorbed under the reaction force of the functional spring.

[0018] 2. By setting the first energy-absorbing rubber ring and the second energy-absorbing rubber ring, when the device is subjected to external impact force, the sliding column moves downward, thereby causing the second pressure plate to move in the rubber cavity, and the second pressure plate drives the first energy-absorbing rubber ring to move downward, so that the first energy-absorbing rubber ring and the second energy-absorbing rubber ring contact and are compressed, and the external impact force is absorbed as the first energy-absorbing rubber ring and the second energy-absorbing rubber ring are compressed.

[0019] 3. By setting the first fixed magnet and the second fixed magnet, when the device is subjected to external impact force, the sliding column moves downward, thereby causing the third pressure plate to move in the magnet cavity. The third pressure plate drives the first fixed magnet to move downward, so that the first fixed magnet and the second fixed magnet are close to each other, and the external impact force is absorbed under the action of the mutually repelling magnetic fields of the two.
