Description

Technical Field

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

[0002] At present, plate dampers are an industrial product used for shock absorption, buffering and sealing. They are widely used in bridges, buildings and other occasions where vibration and impact need to be reduced. The main materials of plate dampers include natural rubber and synthetic rubber. The shape is usually rectangular, square or strip. Its working principle is to absorb and consume vibration energy through the elastic deformation of the damping material, thereby reducing the vibration response of the structure.

[0003] A Chinese utility model patent with announcement number CN202358301U discloses a plate damper including five rigid plates and four sandwich plates located between the five rigid plates. The sandwich plates are rubber blocks located between two metal plates and vulcanized and bonded to the two metal plates as a whole. The four sandwich plates are embedded between the five rigid plates. There are long through grooves extending up and down on the five rigid plates and the four sandwich plates, and there is a clamping limit mechanism consisting of a left pressure plate, a right pressure plate and two clamping bolt assemblies.

[0004] Although the above-mentioned prior art has the advantages of easy processing, low cost, simple installation, overload limiting capability, and easy forming, the damper uses a variety of plates stacked together for energy dissipation and shock absorption. However, the multi-layer plates will squeeze each other during shock absorption, and noise will be generated under high-frequency friction, reducing the use effect. Utility Model Content

[0005] In order to solve the technical problem that multi-layer plates will squeeze each other during shock absorption and generate noise under high-frequency friction, the utility model provides a plate damper.

[0006] The utility model is implemented by the following technical scheme: a plate damper comprises a bottom plate, the top of the bottom plate is provided with an energy absorbing block formed by staggered rubber layers and copper plates, the top of the energy absorbing block is fixedly connected with a top plate, and the outer side of the energy absorbing block is wrapped with protective rubber, and energy dissipation components are provided on both sides of the energy absorbing block for improving the energy dissipation effect, reducing the friction frequency between the rubber layer and the copper plate, and reducing noise.

[0007] As a further improvement of the above solution, the energy dissipation component includes a mounting plate fixedly mounted on opposite surfaces of the bottom plate and the top plate by fastening screws, and an energy-absorbing steel plate and a first spring are fixedly connected between the mounting plates.

[0008] Through the above technical solution, by using the energy-absorbing steel plate and the first spring, buffering and energy absorption can be performed when the damper vibrates, thereby increasing the energy absorption effect and reducing vibration, thereby reducing the generation of noise.

[0009] As a further improvement of the above solution, a vertical rod is connected to the inside of the first spring, and both ends of the vertical rod pass through the bottom plate and the top plate at the same time. Both ends of the vertical rod are connected to buffer blocks arranged inside the bottom plate and the top plate at the same time.

[0010] Through the above technical solution, the function of the vertical rod is to provide stable guidance and support for the damper, ensuring that the damper can move or deform in a predetermined direction when subjected to external force or vibration.

[0011] As a further improvement of the above scheme, the opposite surfaces of the bottom plate and the top plate are fixedly connected with a second spring, the interior of the second spring is provided with a damping sleeve fixedly mounted on the upper surface of the bottom plate, the interior of the damping sleeve is slidably connected with a top column, and the top end of the top column is fixedly connected to the lower surface of the top plate.

[0012] As a further improvement of the above solution, a damping block is arranged inside the damping sleeve, and the top column passes through one end of the damping sleeve and is fixedly connected with a damping plate.

[0013] Through the above technical solution, when the damping plate is driven by the top column to slide in the damping sleeve, the damping block is squeezed, thereby further enhancing the damping effect.

[0014] As a further improvement of the above solution, mounting screws are provided inside the bottom plate and the top plate, and anti-slip pads are fixedly installed on the outer surfaces of the bottom plate and the top plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] When the damper of the utility model is subjected to vibration, the rubber layer and the copper plate are squeezed against each other to reduce shock, and at the same time, the energy-consuming steel plate and the first spring are squeezed to absorb energy and perform buffering. At the same time, the second spring is squeezed, so that when the top column drives the damping plate to slide in the damping sleeve, the damping block is squeezed, thereby further enhancing the damping effect. The design can improve the energy absorption effect, reduce the vibration frequency, reduce the generation of noise, and improve the use effect of the damper. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Example:

[0024] Please combine Figure 1 - Figure 3 The plate damper of this embodiment includes a bottom plate 1, an energy absorbing block formed by staggered rubber layers 5 and copper plates 6 is arranged on the top of the bottom plate 1, a top plate 2 is fixedly connected to the top of the energy absorbing block, and the outer side of the energy absorbing block is wrapped with protective rubber 4, and energy dissipation components are arranged on both sides of the energy absorbing block to improve the energy dissipation effect, reduce the friction frequency between the rubber layer 5 and the copper plate 6, and reduce noise.

[0026] By using the energy-absorbing steel plate 9 and the first spring 12, when the damper vibrates, it can be buffered and energy can be absorbed, thereby increasing the energy absorption effect and reducing vibration, thereby reducing the generation of noise.

[0027] Please combine Figure 2 The first spring 12 is connected with a vertical rod 11 passing through the interior thereof, and both ends of the vertical rod 11 pass through the bottom plate 1 and the top plate 2 at the same time. Both ends of the vertical rod 11 are connected with buffer blocks 10 arranged inside the bottom plate 1 and the top plate 2 at the same time.

[0028] The function of the vertical rod 11 is to provide stable guidance and support for the damper, ensuring that the damper can move or deform in a predetermined direction when subjected to external force or vibration.

[0029] Please combine Figure 3 A second spring 15 is fixedly connected to the opposite surfaces of the bottom plate 1 and the top plate 2. A damping sleeve 13 fixedly installed on the upper surface of the bottom plate 1 is arranged inside the second spring 15. A top column 14 is slidably connected inside the damping sleeve 13. The top end of the top column 14 is fixedly connected to the lower surface of the top plate 2.

[0030] Please combine Figure 3 A damping block 17 is arranged inside the damping sleeve 13 , and a top column 14 passes through the damping sleeve 13 and is fixedly connected to a damping plate 16 at one end.

[0031] When the damping plate 16 is driven by the top column 14 to slide in the damping sleeve 13 , the damping block 17 is squeezed, thereby further enhancing the damping effect.

At the same time, the second spring 15 is squeezed, so that when the top column 14 drives the damping plate 16 to slide in the damping sleeve 13, the damping block 17 is squeezed, thereby further enhancing the damping effect, reducing the vibration frequency and reducing the generation of noise.

[0034] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention.
