Description

Technical Field

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

[0002] In recent years, with the improvement of environmental protection and energy-saving awareness, researchers have begun to pay attention to the design of energy-saving viscoelastic dampers. At present, viscoelastic dampers have been widely used in various engineering fields, including construction, bridges, aerospace, aviation, ships, automobiles, mechanical equipment, etc. With the development of new materials, intelligent control and energy-saving technologies, viscoelastic dampers will continue to play an important role in vibration reduction, noise reduction and high efficiency energy saving.

[0003] However, the existing viscoelastic damper has the following disadvantages:

[0004] (1) Existing viscoelastic dampers have weak applicability. When in use, general viscoelastic dampers can only reduce shaking in a single direction. When shaking in different directions needs to be dealt with at the same time, the installation direction of the viscoelastic damper needs to be fixed according to the actual situation. Increasing the number of viscoelastic dampers installed can easily increase the cost of using the viscoelastic damper.

[0005] (2) The existing viscoelastic damper has a weak stabilizing function. When in use, the general viscoelastic damper cannot effectively reduce the force generated by the up and down shaking, which can easily cause wear on the internal structure of the viscoelastic damper during the up and down shaking process, reducing its stability and service life.

[0024] See also Figure 1-Figure 4 As shown, the utility model provides a technical solution: a high-stability viscoelastic damper, including a first fixed plate 1 and a second fixed plate 2, a plurality of spherical shells 3 are fixedly arranged in the middle of the top end of the first fixed plate 1 and the bottom end of the second fixed plate 2, a support assembly is fixedly arranged inside the spherical shell 3, and the support assembly includes a fixed cylinder 4, a connecting column 5, a sphere 6 and a first viscoelastic damping layer 7, a fixed cylinder 4 is movably arranged between the first fixed plate 1 and the second fixed plate 2, connecting columns 5 are movably arranged at both upper and lower ends of the fixed cylinder 4, a sphere 6 is fixedly arranged at one end of the connecting column 5, a first viscoelastic damping layer 7 is fixedly arranged on the inner surface of the spherical shell 3, and the first viscoelastic damping layer 7 is fixedly connected to the surface of the sphere 6;

[0025] In this embodiment, by setting the fixing cylinder 4, the connecting column 5, the sphere 6 and the first viscoelastic damping layer 7, the whole device is fixed inside the designated position when in use. When the designated position vibrates and causes the whole device to shake back and forth, left and right, the first fixing plate 1 and the second fixing plate 2 will be driven to shake back and forth, left and right. During the shaking process, the fixing cylinder 4 and the connecting column 5 will drive the sphere 6 located on the inner surface of the spherical shell 3 to rotate. The friction between the first viscoelastic damping layer 7 and the sphere 6 and the spherical shell 3 is opposite to the shaking direction of the first fixing plate 1 and the second fixing plate 2, thereby reducing the external force that causes the designated position to shake, thereby achieving the effect of enhancing the application range of the whole device and reducing the use cost of the whole device.

[0026] like Figure 1 As shown, first connecting plates 8 are fixedly arranged on both sides of the top of the first fixing plate 1, a second viscoelastic damping layer 9 is fixedly arranged on one side of the first connecting plate 8, a second connecting plate 10 is fixedly arranged on one side of the second viscoelastic damping layer 9, and the top of the second connecting plate 10 is fixedly connected to the bottom end of the second fixing plate 2;

[0027] In this embodiment, by setting the first connecting plate 8, the second viscoelastic damping layer 9 and the second connecting plate 10, when the designated position shakes up and down, the first connecting plate 8 and the second connecting plate 10 will generate friction with the second viscoelastic damping layer 9, and the friction force generated is opposite to the direction of the up and down shaking, thereby reducing the frequency of mutual squeezing of the internal structure of the overall device, thereby achieving the effect of increasing the service life of the overall device and enhancing its stability;

[0028] like Figure 2 and Figure 4 As shown, both sides of the interior of the fixing cylinder 4 are provided with limiting grooves 11, and both sides of the other end of the connecting column 5 are fixedly provided with limiting blocks 12, and the limiting grooves 11 are movably connected with the limiting blocks 12, and the surface of the spherical shell 3 is provided with a connecting groove 13, and a fixing belt 14 is movably provided inside the connecting groove 13, and a plurality of adjusting holes 15 are provided on both sides of the fixing belt 14, and a screw rod 16 is movably provided inside the adjusting hole 15, and the internal width of the adjusting hole 15 is greater than the width of the screw rod 16, and a first fixing nut 17 is threadedly provided at one end of the screw rod 16, and a second fixing nut 18 is threadedly provided at the other end of the screw rod 16;

[0029] In this embodiment, by setting the limit block 12, when the whole device is shaken up and down during use, the connecting column 5 will drive the limit block 12 to move up and down along the limit groove 11 and the fixing tube 4, so as to avoid the effect of the ball 6 at one end of the connecting column 5 and the inside of the spherical shell 3 being squeezed against each other. By providing a connecting groove 13, the fixing belt 14 is wound around the connecting groove 13 during use, so that the adjustment holes 15 on both sides of the fixing belt 14 correspond to each other, and by inserting the screw 16 into different adjustment holes 15, and then threading the first fixing nut 17 and the second fixing nut 18 on both sides of the screw 16, the two ends of the fixing belt 14 are tightly fitted, so as to achieve the effect of facilitating the adjustment of the tightness between the ball 6 and the spherical shell 3;

[0030] like Figure 1 As shown, a plurality of threaded holes 19 are provided on the surface of the first fixing plate 1 and the second fixing plate 2, and fixing bolts 20 are provided on the inner threads of the threaded holes 19;

[0031] In this embodiment, by providing the threaded hole 19 and the fixing bolt 20, one end of the fixing bolt 20 is passed through the threaded hole 19 and threadedly connected to the external device during use, thereby achieving the effect of making it easy for the installer to fix the entire device at a specified position.

[0032] Working principle: through the setting of the fixed cylinder 4, the connecting column 5, the sphere 6 and the first viscoelastic damping layer 7, the whole device is fixed inside the designated position when in use. When the designated position vibrates and causes the whole device to shake back and forth, left and right, it will drive the first fixed plate 1 and the second fixed plate 2 to shake back and forth, left and right. During the shaking process, the fixed cylinder 4 and the connecting column 5 will drive the sphere 6 located on the inner surface of the spherical shell 3 to rotate. The friction between the first viscoelastic damping layer 7 and the sphere 6 and the spherical shell 3 is opposite to the shaking direction of the first fixed plate 1 and the second fixed plate 2, thereby reducing the external force that causes the designated position to shake, thereby achieving the effect of enhancing the application range of the whole device and reducing the use cost of the whole device. At the same time, through the setting of the first connecting plate 8, the second viscoelastic damping layer 9 and the second connecting plate 10, when the designated position shakes up and down, the first connecting plate 8 and the second connecting plate 10 will generate friction with the second viscoelastic damping layer 9, and the generated friction is opposite to the up and down shaking direction, thereby reducing the frequency of mutual extrusion of the internal structure of the whole device. The effect of improving the service life of the whole device and enhancing its stability is achieved. Through the setting of the limit block 12, when the whole device is shaken up and down during use, the connecting column 5 will drive the limit block 12 to move up and down along the limit groove 11 and the fixing tube 4, thereby avoiding the effect of the ball 6 at one end of the connecting column 5 and the inside of the spherical shell 3 being squeezed against each other. By providing a connecting groove 13, the fixing belt 14 is wrapped around the inside of the connecting groove 13 during use, so that the adjustment holes 15 on both sides of the fixing belt 14 correspond. By inserting the screw 16 into different adjustment holes 15, and then threading the first fixing nut 17 and the second fixing nut 18 on both sides of the screw 16, the two ends of the fixing belt 14 are tightly fitted, thereby achieving the effect of facilitating the adjustment of the tightness between the ball 6 and the spherical shell 3. Through the setting of the threaded hole 19 and the fixing bolt 20, one end of the fixing bolt 20 is passed through the inside of the threaded hole 19 and is threadedly connected to the external device during use, thereby achieving the effect of facilitating the installer to fix the whole device at a specified position.
