Description

Technical Field

[0001] The present application relates to the technical field of viscoelastic dampers, and in particular to a viscoelastic damper that is easy to install. Background Art

[0002] Viscoelastic damper is a kind of viscous damping device with rigidity. It plays an important role in structural engineering. Viscoelastic damper has strong energy dissipation capacity. It is widely used in engineering projects such as buildings, bridges, airport runways, wind power generation equipment, etc., especially in high-risk projects such as high-rise buildings and long-span bridges. Viscoelastic damper is mainly composed of viscoelastic damping material and constrained steel plate alternately overlapped and bonded. When the viscoelastic damper is subjected to external force, the outer steel plate transfers the force acting on the steel plate to the viscoelastic material, causing the viscoelastic material to shear deformation. The viscoelastic material will store part of the energy in the material, and the other part of the energy will be dissipated by heat energy consumption.

[0003] In the prior art, screws are usually used for fastening. Screws are respectively set at the upper and lower ends of the steel plate, and then the elastic damper is fixed by screwing in the screws. During the fastening process, each screw needs to be fastened separately, and when the viscoelastic damper needs to be disassembled, each screw also needs to be disassembled, which makes installation and disassembly inconvenient.

[0027] Example 1

[0028] Reference Figure 1-Figure 4 The first embodiment of the present application provides a viscoelastic damper that is easy to install, including a damper body, and fixing plates 10 are respectively arranged at both ends of the damper body, wherein at least one first steel plate 11 is arranged on one of the fixing plates 10, and at least one second steel plate 12 is arranged on the other fixing plate 10, the first steel plate 11 and the second steel plate 12 are staggered, and a rubber viscoelastic layer 13 is arranged between the first steel plate 11 and the second steel plate 12, and the two fixing plates 10 are respectively provided with at least one locking assembly 20, and the locking assembly 20 includes a locking rod 21, a driving unit 23 and a receiving groove 22 located at both ends of the fixing plate 10; wherein at least parts of the two locking rods 21 are located in the corresponding receiving grooves 22; the driving unit 23 is configured to drive the two locking rods 21 to move in a direction away from each other to adjust the distance between the distal ends of the two locking rods 21.

[0029] In this embodiment, the first steel plate 11, the second steel plate 12 and the rubber viscoelastic layer 13 constitute the damper body. The two fixed plates 10 are arranged opposite to each other. During use, the two fixed plates 10 are respectively fixed on the two components to be connected. The components can be walls. The side walls of the two components facing each other are provided with mounting grooves. The height and width of the mounting grooves are respectively greater than the corresponding height and width of the fixed plates 10, so that the fixed plates 10 can be accommodated in the mounting grooves (not shown in the figure). One end of all the first steel plates 11 is connected to the side wall of one of the fixed plates 10, and the other end of all the first steel plates 11 is a free end; one end of all the second steel plates 12 is connected to the side wall of the other fixed plate 10, and the other end of all the second steel plates 12 is a free end. The free ends of the first steel plates 11 and the free ends of the second steel plates 12 are staggered, and the rubber viscoelastic layer 13 is arranged between the adjacent first steel plates 11 and the second steel plates 12. The rubber viscoelastic layer 13 is made of a rubber material, and has both viscosity and elasticity. Due to the viscoelastic properties of the rubber material, the rubber viscoelastic member can effectively absorb and disperse impact energy, thereby having good shock absorption and seismic isolation performance. When one of the fixed plates 10 is subjected to an external force, or when both fixed plates 10 are subjected to an external force at the same time, the outer steel plate transmits the force acting on the steel plate to the viscoelastic material, causing the viscoelastic material to shear and deform. The viscoelastic material will store part of the energy in the material, and the other part of the energy will be dissipated by heat energy consumption.

[0030] The two fixing plates 10 can be symmetrically arranged, and at least one locking assembly 20 arranged on the fixing plate 10 is arranged and distributed along the first direction. The first steel plate 11 and the second steel plate 12 extend along the second direction, and the first direction and the second direction are perpendicular to each other. The two receiving grooves 22 of the same locking assembly 20 are coaxially arranged, and the receiving groove 22 extends along the third direction. The first direction, the second direction and the third direction are perpendicular to each other. The two locking rods 21 of the locking assembly 20 are respectively arranged in the two receiving grooves 22, and the locking rods 21 can be partially located in the receiving grooves 22, or can be completely accommodated in the receiving grooves 22. Under the action of the driving unit 23, the two locking rods 21 are driven to move outward, the two locking rods 21 are coaxially arranged, and the distal ends of the two locking rods 21 protrude from the receiving grooves 22. The two locking rods 21 abut against the inner walls of the upward ends or the left and right ends of the installation groove to achieve the locking of the two locking rods 21, which plays a role in fixing the fixing plate 10. During the installation process, the two fixing plates 10 can be installed first and then the two fixing plates 10 can be installed in the installation groove. When installing the fixing plate 10, it is only necessary to control the movement of the driving unit 23 to quickly drive the two locking rods 21 on the fixing plate 10, so that the two locking rods 21 cooperate with the inner wall of the installation groove, thereby indirectly installing the fixing plate 10 in the installation groove. Compared with the prior art, during the installation and disassembly process, there is no need to repeatedly rotate multiple screws, thereby improving the efficiency of installation and disassembly.

[0031] Example 2

[0032] As an optional implementation, refer to Figure 1-Figure 3 The present embodiment provides a specific structure of a locking rod 21, including: the notch of the accommodating groove 22 is a constricted structure, a baffle 30 is provided at one end of the locking rod 21 located in the accommodating groove 22, and a return spring 31 is sleeved on the part of the locking rod 21 located in the accommodating groove 22, and the return spring 31 is located between the baffle 30 and the notch.

[0033] In this embodiment, the size of the notch of the receiving groove 22 is smaller than the size of the inner wall of the receiving groove 22. By setting a reset spring 31 at the notch position of the baffle 30 and the receiving groove 22, the reset spring 31 is in a compressed state, so that the two locking rods 21 always have a tendency to move toward the bottom wall of the receiving groove 22. That is, in the initial state, the distance between the far ends of the two locking rods 21 is close, so that the fixing plate 10 can be installed in the installation groove. And during the disassembly of the viscoelastic damper, after the driving component cancels the external force on the locking rod 21, the locking rod 21 can automatically move inward under the action of the reset spring 31, so that the locking rod 21 automatically detaches from the inner wall of the installation groove, and quick disassembly is achieved. Yes

One end of the driving rod 232 is a conical surface. When the driving rod 232 moves along the driving hole 50, the conical surface of the driving rod 232 contacts the arc surface of the guide rod 231, and a component force along its axial direction is applied to the guide rod 231, pushing the two guide rods 231 to move in a direction close to their corresponding locking rods 21, and the guide rods 231 abut against the locking rods 21 and push the locking rods 21 to move. It should be noted that when the driving rod 232 is not connected to other power structures, the driving rod 232 and the driving hole 50 can be threaded. During the installation process, it is only necessary to screw in the driving rod 232 to complete the installation. Similarly, when disassembly is required, the driving rod 232 can be screwed back.

[0042] In this embodiment, by providing multiple locking units, the contact area between the locking rod 21 and the mounting groove is increased, thereby improving the installation stability of the fixed plate 10. By simultaneously connecting all the driving rods 232 on the same fixed plate 10 through the driving plate 60, when all the locking assemblies 20 are locked, it is only necessary to push the driving plate 60 to move, thereby further improving the installation efficiency of the fixed plate 10. A buckle sub-component 61 is provided on the driving plate 60, and a buckle mother component 62 is provided on the fixed plate 10. The buckle sub-component 61 cooperates with the buckle mother component 62 to form a limiting structure, which plays a fixing role on all the driving rods 232, so that the driving rod 232 and the locking rod 21 can maintain a state of being tightly pressed against the inner wall of the mounting groove. One end of the buckle component 61 is interconnected with the driving plate 60, and the other end of the buckle component 61 is a free end. One end of the buckle mother component 62 is interconnected with the fixing plate 10, and the other end of the buckle mother component 62 is a free end.
