Description

TECHNICAL FIELD

[0001] The application relates to the technical field of shock-absorbing devices, in particular to an energy-dissipation shock-absorbing device with a deformation amplification function. BACKGROUND

[0002] The beam is a horizontal component that bears the load of a roof panel and the like. The column is a vertical force component that is responsible for transmitting the load on the beam.

[0003] The functions of the beam and the column are as follows: the beam transfers the load to the column, the column further transfers the load to the foundation, and the foundation further transfers the load to the ground. The beam mainly bears the bending moment, and the column mainly bears the axial force.

[0004] In the prior art, a hydraulic damper is generally directly installed between the beam and the column to achieve the damping effect. However, the damping effect of the hydraulic damper is fixed and limited, and it is difficult to adapt to variable load conditions. SUMMARY

[0005] The application aims to provide an energy-dissipation shock-absorbing device with a deformation amplification function to solve the problem that the column installed at a high position is prone to deformation.

[0006] In a first aspect, the application provides an energy-dissipation shock-absorbing device with a deformation amplification function, which adopts the following technical scheme: The energy-dissipation shock-absorbing device with a deformation amplification function comprises a column and a beam, the column and the beam are connected, further comprises a vertical rod and a support rod, the vertical rod is installed on the beam, a damping disc is rotatably connected to the vertical rod, one end of the support rod is hingedly connected to the column, the other end of the support rod is connected to the vertical rod, a rotating rod is connected to the junction of the beam and the column, the rotating rod is hingedly connected to the damping disc, the vertical rod is connected to the disc surface of the damping disc through a metal energy-dissipation damping member, and the metal energy-dissipation damping member exerts damping through the deformation that can be reset.

[0007] By adopting the above technical scheme, the damping disc is connected to the support rod and the vertical rod at the same time, the damping disc converts the linear motion of the rotating rod into circular motion, and amplifies the small displacement at the junction of the column and the beam. Through the amplified displacement, the damping effect of the metal energy-dissipation damping member is fully exerted, the impact load is buffered, the energy of the impact load input into the structure is absorbed, the eccentric load stress is converted from single-point concentration to circular uniform distribution, the fatigue risk of the structure is reduced, the fatigue life is prolonged, in addition, the vibration transmission is converted from one-way resonance to vortex dissipation, the damage and destruction of the structure are reduced, and the damping effect is improved.

[0008] Optionally, the center of rotation of the vertical rod and the damping disc is offset from the axis of the damping disc.

[0009] Through the technical scheme, the distance between the metal energy dissipation damping piece and the rotation center of the damping disc is increased by setting the rotation center to be offset from the shaft center, the vibration between the beam and the column is further amplified, and the building effect is improved.

[0010] Optionally, the rotating rod is obliquely arranged and forms a triangle with the beam and the vertical rod.

[0011] Through the technical scheme, the rotating rod forms a triangle with the beam and the vertical rod, the stability of the structure is improved, and the damping vibration reduction effect of the metal energy dissipation damping piece and the damping disc on the column is ensured.

[0012] Optionally, the minimum distance between the support rod and the damping disc axis is smaller than the minimum distance between the metal energy dissipation damping piece and the damping disc.

[0013] Through the technical scheme, the minimum distance between the support rod and the damping disc axis is smaller than the minimum distance between the metal energy dissipation damping piece and the damping disc, the small deformation of the column can be converted into a larger deformation of the metal energy dissipation damping piece, and the damping force exerted by the metal energy dissipation damping piece on the column is improved to better prevent the deformation of the column.

[0014] Optionally, the distance between the support rod and the damping disc hinge point and the damping disc axis is defined as a, the distance between the metal energy dissipation damping piece and the damping disc axis is defined as b, and the ratio between a and b is 1:1.2 to 1:3.

[0015] Through the technical scheme, by controlling the ratio between a and b, when the ratio is larger, the deformation of the metal energy dissipation damping piece is larger for the same deformation of the column, and the damping force exerted on the column is also larger, and thus the appropriate damping force can be exerted on the column by adjusting the ratio between a and b.

[0016] Optionally, the metal energy dissipation damping piece is made of a material that can deform and reset, and the metal energy dissipation damping piece is inserted between the vertical rod and the damping disc.

[0017] Through the technical scheme, the metal energy dissipation damping piece is inserted between the damping disc and the vertical rod, which facilitates the exertion of damping force on the column in two directions, and when the column deforms or shakes in these two directions, the metal energy dissipation damping piece can exert effective damping force. At the same time, the metal energy dissipation damping piece is subjected to shear force, so that when the metal energy dissipation damping piece deforms, it can exert a larger damping force.

[0018] Optionally, the metal energy dissipation damping piece is arranged parallel to the damping disc surface, one end of the metal energy dissipation damping piece is connected to the vertical rod, and the other end is connected to the damping disc surface.

[0019] By adopting the above technical solution, and by placing the metal energy dissipation damping component parallel to the surface of the damping disc, the metal energy dissipation damping component bears tensile and compressive forces. In these two directions, the metal energy dissipation damping component can withstand greater loads and has a longer service life.

[0020] Optionally, multiple metal energy dissipation damping elements are provided along the radial direction of the damping disc.

[0021] Through the above technical solution, by arranging multiple metal energy-dissipating damping components along the radial direction of the damping disc, when the damping disc is rotated by the support rod, initially, the damping force applied by the metal energy-dissipating damping components near the axis of the damping disc is relatively small. However, as the rotation angle of the damping disc increases, the damping force applied by each metal energy-dissipating damping component to the damping disc will gradually increase. Moreover, the metal energy-dissipating damping component closer to the axis of the damping disc is more capable of applying a larger damping force to the support rod with a smaller deformation. Therefore, it can effectively control the deformation range of the column and prevent the column from being punctured due to excessive deformation.

[0022] Optionally, there are two damping discs, which are fixed to each other, and a fixing block is provided between the two damping discs. The metal energy dissipation damping component is located between the fixing block and the vertical rod.

[0023] By adopting the above technical solution, the stable rotation of the damping disc is ensured through the cooperation of the fixed block and the vertical rod, while the tension and compression of the metal energy dissipation damping component are relatively stable.

[0024] Optionally, the cross-section of the metal energy dissipation damping element is circular, elliptical, or polygonal.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The damping disc is connected to both the support rod and the vertical rod. The damping disc transforms the linear motion of the rotating rod into circular motion and amplifies the small displacement at the junction of the column and beam. Through the amplified displacement, the damping effect of the metal energy dissipation damping component is fully utilized to buffer the impact load and absorb the energy input to the structure. At the same time, the eccentric stress is transformed from a single-point concentration to a circumferentially distributed stress, reducing the fatigue risk of the structure and extending its fatigue life. In addition, the vibration transmission is transformed from unidirectional resonance to vortex dissipation, which greatly reduces the damage and destruction of the structure and improves the vibration reduction effect. 2. By setting the rotation center to deviate from the axis, the distance between the metal energy dissipation damping component and the rotation center of the damping disc is increased, further amplifying the vibration between the beam and the column, thereby improving the building effect; 3. By rotating the rod to form a triangle with the beam and vertical rod, the stability of the structure is improved, thereby ensuring the damping and vibration reduction effect of the metal energy dissipation damping components and damping disc on the column; 4. The minimum distance between the support rod and the damping disc axis is less than the minimum distance between the metal energy dissipation damper and the damping disc, which can convert the small deformation of the column into a larger deformation of the metal energy dissipation damper, thereby increasing the damping force applied by the metal energy dissipation damper to the column, so as to better prevent the deformation of the column. 5. By controlling the ratio between a and b, the larger the ratio, the greater the deformation of the metal energy dissipation damping component for the same amount of deformation of the column, and the greater the damping force applied to the column. Thus, by adjusting the ratio between a and b, a suitable damping force can be applied to the column. 6. Insert the metal energy dissipation damping component between the damping disc and the vertical rod to facilitate the application of damping force in two directions to the column. When the column deforms or sways in these two directions, the metal energy dissipation damping component can apply effective damping force. At the same time, the metal energy dissipation damping component is subjected to shear force, so when the metal energy dissipation damping component deforms, it can apply a large damping force. 7. By aligning the metal energy dissipation damper parallel to the surface of the damping disc, the metal energy dissipation damper bears both tensile and compressive forces. In these two directions, the metal energy dissipation damper can withstand greater loads and has a longer service life. 8. By arranging multiple metal energy-dissipating damping elements along the radial direction of the damping disc, when the damping disc is rotated by the support rod, initially, the damping force applied by the metal energy-dissipating damping elements near the axis of the damping disc is relatively small. However, as the rotation angle of the damping disc increases, the damping force applied by each metal energy-dissipating damping element to the damping disc will gradually increase. Moreover, the metal energy-dissipating damping element closer to the axis of the damping disc is more able to apply a larger damping force to the support rod with a smaller deformation. Therefore, it can effectively control the deformation range of the column and prevent the column from being punctured due to excessive deformation. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0037] Example 1: Firstly, this application discloses an energy dissipation and vibration reduction device with deformation amplification function.

[0038] A vibration damping device with deformation amplification function, referring to Figures 1 to 2 The system includes a column 2, a beam 1, a vertical rod 3, and a support rod 4. The column 2 is connected to the beam 1. The vertical rod 3 is fixedly installed on the beam 1, and a damping disc 5 is rotatably connected to the vertical rod 3. A rotating rod 51 is fixedly connected at the junction of the beam 1 and the column, and the rotating rod 51 is hinged to the damping disc 5. One end of the support rod 4 is hinged to the column 2, and the other end is fixedly connected to the vertical rod 3. A metal energy-dissipating damping element 6 is also connected between the vertical rod 3 and the damping disc 5. The metal energy-dissipating damping element 6 applies damping to the support rod 4 through its restorable deformation. The support rod 4 is connected to both the vertical rod 3 and the column 2. It applies damping to the column 2 through the deformation of the metal energy-dissipating damping element 6, and absorbs vibration energy during the deformation process, gradually reducing the vibration and deformation of the column 2, thereby ensuring the safety of the column 2.

[0039] Specifically, the damping disc 5 is connected to both the support rod 4 and the vertical rod 3. The damping disc 5 transforms the linear motion of the support rod 4 into circular motion, buffering the impact load and absorbing the energy input to the structure. At the same time, it transforms the eccentric stress from a single point concentration to a circumferential distribution, reducing the fatigue risk of the structure and extending its fatigue life. In addition, the vibration transmission is transformed from unidirectional resonance to vortex dissipation, which greatly reduces the damage and destruction of the structure and improves the vibration reduction effect.

[0040] More specifically, the rotating rod 51 is inclined and forms a triangle with the beam 1 and the vertical rod 3. By forming a triangle with the beam 1 and the vertical rod 3, the stability of the structure is improved, thereby ensuring the damping and vibration reduction effect of the metal energy dissipation damping component 6 and the damping disk 5 on the column 2.

[0041] In this embodiment, the length direction of the metal energy dissipation damping member 6 is consistent with the axial direction of the damping disk 5, that is, the metal energy dissipation damping member 6 is inserted into both the damping disk 5 and the vertical rod 3.

[0042] When the number of metal energy-dissipating damping elements 6 is 1, the minimum distance between the axis of the support rod 4 and the damping disk 5 is less than the minimum distance between the metal energy-dissipating damping element 6 and the damping disk 5. This smaller distance between the axis of the support rod 4 and the damping disk 5 allows the smaller deformation of the column 2 to be converted into a larger deformation of the metal energy-dissipating damping element 6, thereby increasing the damping force applied by the metal energy-dissipating damping element 6 to the column 2, and better preventing the deformation of the column 2.

[0043] Define 'a' as the distance between the hinge point of the support rod 4 and the damping disk 5 and the axis of the damping disk 5, and define 'b' as the distance between the metal energy-dissipating damper 6 and the axis of the damping disk 5. The ratio of a to b is 1:1.2 to 1:3. By controlling the ratio of a to b, the larger the ratio, the greater the deformation of the metal energy-dissipating damper 6 for the same amount of deformation of the column 2, and the greater the damping force applied to the column 2. Thus, by adjusting the ratio of a to b, a suitable damping force can be applied to the column 2.

[0044] The metal energy dissipation damping element 6 is made of a material capable of deformation and recovery, such as a lead core or a high-damping rubber rod. The metal energy dissipation damping element 6 is inserted between the vertical rod 3 and the damping disc 5. Inserting the metal energy dissipation damping element 6 between the damping disc 5 and the vertical rod 3 facilitates the application of damping forces in two directions to the column 2. When the column 2 deforms or sways in either of these directions, the metal energy dissipation damping element 6 can apply effective damping forces. Simultaneously, the metal energy dissipation damping element 6 is subjected to shear force, therefore, when the metal energy dissipation damping element 6 deforms, it can apply a relatively large damping force.

[0045] Optionally, the cross-section of the metal energy dissipation damping element 6 can be circular, elliptical, or polygonal.

[0046] Example 2: The difference from Embodiment 1 is that, referring to Figure 3 The metal energy-dissipating damping element 6 is arranged parallel to the surface of the damping disk 5. One end of the metal energy-dissipating damping element 6 is connected to the vertical rod 3, and the other end is connected to the surface of the damping disk 5. By aligning the metal energy-dissipating damping element 6 parallel to the surface of the damping disk 5, the metal energy-dissipating damping element 6 bears both tensile and compressive forces. In these two directions, the metal energy-dissipating damping element 6 can withstand greater loads and has a longer service life.

[0047] Two damping discs 5 are provided, and the two damping discs 5 are fixed to each other. A fixing block 52 is provided between the two damping discs 5. The metal energy dissipation damping element 6 is located between the fixing block 52 and the vertical rod 3. The fixing block 52 and the vertical rod 3 cooperate to ensure the stable rotation of the damping discs 5, and at the same time ensure the relatively stable tension and compression of the metal energy dissipation damping element 6.

[0048] Example 3: The difference from Embodiment 1 is that, referring to Figure 4Multiple metal energy-dissipating damping elements 6 are arranged radially along the damping disk 5. By arranging multiple metal energy-dissipating damping elements 6 along the radial direction of the damping disk 5, when the damping disk 5 is rotated by the support rod 4, initially, the damping force applied by the metal energy-dissipating damping elements 6 near the axis of the damping disk 5 is relatively small. However, as the rotation angle of the damping disk 5 increases, the damping force applied by each metal energy-dissipating damping element 6 to the damping disk 5 gradually increases. Furthermore, the metal energy-dissipating damping elements 6 closer to the axis of the damping disk 5 can apply a larger damping force to the support rod 4 with smaller deformations. Therefore, it can effectively control the deformation range of the column 2 and prevent the column 2 from being punctured due to excessive deformation. The dimensions of the multiple metal energy-dissipating damping elements 6 gradually increase along the direction from the vertical rod 3 towards the damping disk 5, thereby increasing the damping provided by the metal energy-dissipating damping elements 4 exponentially along the direction from the vertical rod 3 towards the damping disk 5, improving the damping range provided by the metal energy-dissipating damping elements 4, and enhancing its versatility.

[0049] It should be noted that the metal energy dissipation damping element 6 in Embodiment 2 can also be arranged radially along the damping disk 5.

[0050] Example 4: The difference from Embodiment 1 is that, referring to Figure 5 and Figure 6 A supplementary damping assembly 7 is provided on beam 1, and the supplementary damping assembly 7 is arranged along the axial direction of the damping disk 5. The supplementary metal energy dissipation damping component 6 includes a damping box 71 and a resistance box 72. There are two resistance boxes 72, which are located on both sides of the damping box 71 along the axial direction of the damping disk 5. Each end of the resistance box 72 is provided with a slide rod 73. Each slide rod 73 is inserted into a damping box 71 and fixedly connected to a piston 75. Each slide rod 73 is also fitted with a first compression spring 74, and the two ends of each first compression spring 74 abut against the damping box 71 and a resistance box 72, respectively. A hinge rod 76 is hinged to the damping box 71. The end of the hinge rod 76 away from the damping box 71 is hinged to the column 2 so as to apply a damping force to the column 2 along the axial direction of the damping disk 5.

[0051] The supplementary damping assembly 7 is provided in two sets, which are arranged on both sides of the column 2 along the axial direction of the damping disc 5.

[0052] When column 2 vibrates or deforms along the axial direction of damping disc 5, damping box 71 also undergoes a certain displacement. During this displacement, damping box 71 encounters resistance from the first compression spring 74 and the air within the resistance box 72, thus applying damping to column 2 and preventing deformation or amplification of vibration. Simultaneously, the expansion and contraction of the first compression spring 74, the compression and release of air, dissipate vibration energy, thereby reducing vibration in column 2. Furthermore, the supplementary damping assembly 7 works in conjunction with damping disc 5. Damping disc 5 bears the primary force direction, while supplementary damping assembly 7 bears the secondary force direction; together, they ensure the stability of column 2.

[0053] Example 5: The difference from Embodiment 1 is that, referring to Figure 7 and Figure 8 An adjusting rod is slidably connected inside the rotating rod, and a locking bolt is threaded onto the side wall of the rotating rod to lock the adjusting rod. A sliding block is slidably connected within the damping disc, hinged to the adjusting rod. The sliding block has a locking mechanism to lock it relative to the side wall of the sliding disc. An active support is connected to the bottom of the beam, and an actuator is fixedly connected to the active support. The output end of the actuator is hinged to the surface of the damping disc. A vibration sensor is installed at the junction of the beam and column, and is electrically connected to the actuator. The sliding block can slide on the sliding groove, thereby adjusting the position of the hinge point between the adjusting rod and the damping disc. This facilitates installation and allows adjustment of the distance between the hinge point of the adjusting rod and the damping disc, and between the center of rotation of the damping disc, thus achieving a distance that effectively suppresses vibration at the beam-column junction. Furthermore, the electrical connection between the actuator and the vibration sensor allows the actuator to apply an active force to the damping disc when there is significant vibration between the beam and column, thereby better eliminating the vibration.

[0054] Specifically, the locking element includes a locking block and a second compression spring. A slot is formed on the side wall of the slider, and the locking block slides within the slot. The second compression spring is located between the locking block and the bottom of the slot. Multiple limiting grooves for the locking block to engage are formed on the side wall of the slider along its length. A lever is fixedly connected to the side wall of the locking block, with one end of the lever extending out of the slider to adjust its position.

[0055] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
