According to the plate-type viscoelastic damper, by arranging the restoring assembly and the resetting assembly, when the first damping plate or the second damping plate moves due to the pulling force on the plate-type viscoelastic damper, the viscoelastic block is pulled to deform, the restoring assembly pulls the first damping plate or the second damping plate when the first damping plate or the second damping plate moves, and the moving distance is reduced; the reset assembly can limit the moving distance of the first damping plate when the first damping plate moves, the situation that the deformation degree of the viscoelastic block is increased due to the fact that the moving distance of the first damping plate is too large is prevented, and when the plate type viscoelastic damper is subjected to extrusion force, the plate type viscoelastic damper is not prone to deformation; and the reset assembly can also support the two second damping plates, so that the deformation degree of the viscoelastic block due to extrusion is reduced.

Description

Technical Field

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

[0002] Energy dissipation and shock absorption of building structures refers to the installation of special energy dissipation components or devices in the building structure to increase the structural damping so that when there is a strong earthquake, the energy input into the structural system by the earthquake vibration can be absorbed and consumed to protect the safety of the main structure. The viscoelastic damper is a typical passive control device that can exert a vibration control effect without a large relative deformation. It can be applied to the seismic response and wind vibration control of the structure at the same time. Since the plate-type viscoelastic damper is very important and widely used, it is necessary to optimize it.

[0003] For example, a Chinese utility model patent with announcement number CN205663055U discloses a fireproof viscoelastic damper with adjustable damping force. Although the above-mentioned prior art has fireproof and heat-insulating functions, higher damping force and equivalent damping ratio, and can be used in a wider temperature range to improve its safety of use, the working principle of the viscoelastic damper is based on the viscoelastic properties of the material, and absorbs and dissipates energy through the deformation of the material. Therefore, when the vibration causes the viscoelastic block of the plate-type viscoelastic damper to deform, its shape will be permanently deformed to a certain extent. This deformation is irreversible and cannot be completely restored by simple external force. However, this does not mean that the damper has lost its function, but it will reduce the service life of the damper, increase the maintenance and replacement frequency, and easily cause waste of resources. Therefore, it is necessary to design a new plate-type viscoelastic damper that can reduce the deformation degree of the viscoelastic block of the plate-type viscoelastic damper. Utility Model Content

[0004] In order to solve the technical problem that the service life of the viscoelastic block of the plate-type viscoelastic damper is affected by the lack of auxiliary recovery after deformation, the utility model provides a novel plate-type viscoelastic damper.

[0005] The utility model is implemented by the following technical scheme: a novel plate-type viscoelastic damper, comprising a first damping plate, both sides of which are provided with viscoelastic blocks, one side of each of the two viscoelastic blocks is fixedly provided with a second damping plate, one side of the first damping plate is provided with a restoration component for assisting the viscoelastic block to restore after the viscoelastic block moves and deforms, and a restoration component for assisting the viscoelastic block to restore after the viscoelastic block is squeezed and deformed is provided between the two second damping plates.

[0006] Through the above technical solution, when the viscoelastic block is deformed, the positions of the first damping plate and the second damping plate will be moved, the recovery component will pull the second damping plate to restore the position, and the reset component will reduce the moving distance of the first damping plate and the second damping plate.

[0007] As a further improvement of the above scheme, the restoration assembly includes limit plates fixedly installed on both sides of the first damping plate, a plurality of pulling columns arranged on one side of each limit plate, and a return spring arranged on each pulling column, and one end of each pulling column passes through the adjacent limit plate and is fixedly installed with the adjacent second damping plate.

[0008] Through the above technical solution, when the first damping plate and the second damping plate are displaced, the return spring cooperates with the pulling column and the limit plate to pull the first damping plate and the second damping plate to return to their original position.

[0009] As a further improvement of the above solution, one end of each of the return springs is fixedly mounted to the adjacent limit plate, the other end of each of the return springs is fixedly mounted to the adjacent second damping plate, and one end of each of the pulling columns is fixedly mounted with a limit block.

[0010] Through the above technical solution, no matter which direction the first damping plate and the second damping plate move to, the return spring will pull them to return to their original position.

[0011] As a further improvement of the above scheme, the reset assembly includes a fixed plate fixedly installed on one side of the first damping plate and a plurality of reset columns arranged on one side of the fixed plate, one end of each of the reset columns passes through the fixed plate, both ends of each of the reset columns are provided with sliding bars with sliding grooves, each of the sliding bars is fixedly installed with the adjacent second damping plate, and each of the reset columns slides with the adjacent sliding bars through adjacent sliding grooves.

[0012] Through the above technical solution, when the first damping plate moves, the moving distance will be limited by the reset column and the sliding bar, so as to prevent the first damping plate from moving too far.

[0013] As a further improvement of the above scheme, both ends of each reset column are fixedly sleeved with a limiting plate, one side of each limiting plate is provided with a pushing spring sleeved on the adjacent reset column, and one end of each pushing spring is fixedly installed with the fixed plate.

[0014] Through the above technical solution, when the viscoelastic block is squeezed and deformed, the push spring will open the second damping plate to reduce the degree of squeeze deformation of the viscoelastic block.

[0015] As a further improvement of the above solution, rubber plates are fixedly mounted on both sides of the fixing plate, and one side of the two rubber plates is fixedly mounted to one side of the first damping plate.

[0016] Through the above technical solution, when the first damping plate moves, the two rubber plates will be pulled, and the pulling of the two rubber plates will reduce the movement degree of the first damping plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a restoring component and a resetting component. When the plate-type viscoelastic damper is subjected to a pulling force causing the first damping plate or the second damping plate to move, the viscoelastic block will be pulled to deform. The restoring component will pull the first damping plate or the second damping plate when it moves to reduce the moving distance, thereby reducing the degree of deformation of the viscoelastic block caused by being pulled. The resetting component will limit the moving distance of the first damping plate when it moves to prevent the first damping plate from moving too far and causing an increase in the degree of deformation of the viscoelastic block. When the plate-type viscoelastic damper is subjected to an extruding force, the resetting component will also support the two second damping plates to reduce the degree of deformation of the viscoelastic block caused by being extruded. This arrangement can not only reduce the degree of deformation of the viscoelastic block in multiple directions, but also limit the moving distance of the first damping plate and the second damping plate.

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. 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.

[0025] Please combine Figure 1-Figure 3A novel plate-type viscoelastic damper of the present embodiment includes a first damping plate 1, viscoelastic blocks 2 are installed on both sides of the first damping plate 1, and second damping plates 3 are fixedly installed on one side of the two viscoelastic blocks 2. A restoring component for assisting the viscoelastic block 2 to restore after the viscoelastic block 2 moves and deforms is provided on one side of the first damping plate 1, and a restoring component for assisting the viscoelastic block 2 to restore after the viscoelastic block 2 is squeezed and deformed is provided between the two second damping plates 3.

[0026] Combination Figure 1 and Figure 2 The restoration component includes a limit plate 401 fixedly installed on both sides of the first damping plate 1, a plurality of pulling columns 402 arranged on one side of each limit plate 401, and a return spring 403 sleeved on each pulling column 402, one end of each pulling column 402 passes through the adjacent limit plate 401 and is fixedly installed with the adjacent second damping plate 3, one end of each return spring 403 is fixedly installed with the adjacent limit plate 401, the other end of each return spring 403 is fixedly installed with the adjacent second damping plate 3, and one end of each pulling column 402 is fixedly installed with a limit block 6. When the first damping plate 1 and the second damping plate 3 are displaced, the return spring 403 cooperates with the pulling column 402 and the limit plate 401 to pull the first damping plate 1 and the second damping plate 3 to reset them.

[0027] Combination Figure 1-Figure 3 The reset assembly includes a fixed plate 501 fixedly mounted on one side of the first damping plate 1 and a plurality of reset columns 502 arranged on one side of the fixed plate 501. One end of each reset column 502 passes through the fixed plate 501. Both ends of each reset column 502 are provided with a sliding bar 7 with a sliding groove. Each sliding bar 7 is fixedly mounted with the adjacent second damping plate 3. Each reset column 502 is slidably matched with the adjacent sliding bar 7 through the adjacent sliding groove. Both ends of each reset column 502 are fixedly sleeved with a limiting plate 8. One side of each limiting plate 8 is provided with a pushing spring 9 sleeved on the adjacent reset column 502. Each pushing spring One end of 9 is fixedly installed with the fixed plate 501, and rubber plates 10 are fixedly installed on both sides of the fixed plate 501. One side of the two rubber plates 10 is fixedly installed with one side of the first damping plate 1. When the first damping plate 1 moves, the moving distance will be limited by the reset column 502 and the sliding bar 7 to prevent the first damping plate 1 from moving too far. When the viscoelastic block 2 is squeezed and deformed, the push spring 9 will open the second damping plate 3 to reduce the degree of squeezing and deformation of the viscoelastic block 2. When the first damping plate 1 moves, it will pull the two rubber plates 10, and the pulling of the two rubber plates 10 will reduce the movement of the first damping plate 1.

[0028] The implementation principle of a novel plate-type viscoelastic damper in the embodiment of the present application is as follows: when the plate-type viscoelastic damper is vibrated, the lateral vibration will cause the first damping plate 1 or the second damping plate 3 to move, and during the movement, the viscoelastic block 2 will be pulled for damping and shock reduction. When the first damping plate 1 or the second damping plate 3 moves, the reset spring 403 will be stretched or squeezed, and during the recovery process of the reset spring 403, the second damping plate 3 or the limit plate 401 will be pulled or pushed away, reducing the moving distance between the first damping plate 1 and the second damping plate 3, thereby reducing the degree of pulling of the viscoelastic block 2, and after the vibration ends, such force will also pull the first damping plate 1 and the second damping plate 3 to reset, thereby helping the viscoelastic block 2 to The first damping plate 1 and the second damping plate 3 can perform a certain degree of shape recovery to extend the service life of the viscoelastic block 2. When the first damping plate 1 and the second damping plate 3 move, the first damping plate 1 will also drive the fixed plate 501 to move, so that the reset column 502 can slide inside the sliding groove. The sliding distance of the sliding groove is fixed, so it can be avoided that the first damping plate 1 moves too far and causes a large deformation to the viscoelastic block 2. The reset component cooperates with the recovery component to limit the moving distance of the first damping plate 1 and the second damping plate 3 to prevent the viscoelastic block 2 from being deformed too much and causing a reduction in service life. This arrangement can not only reduce the moving distance of the first damping plate 1 and the second damping plate 3, but also help the viscoelastic block 2 to recover its shape and extend its service life.

[0029] 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. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
