Description

Technical Field

[0001] This invention relates to the field of viscous damping walls, and particularly to an amplification device for adjustable viscous damping walls. Background Technology

[0002] Viscous damping walls utilize the relative motion between structural layers to dissipate energy. However, in existing technologies, the energy dissipation effect of viscous damping walls is limited. While the damping force of a viscous damping wall can be adjusted by changing the viscosity of the viscous liquid, the distance between the inner and outer steel plates, and the area of ​​the steel plates, both methods have drawbacks. Changing the viscosity requires changing the type of liquid, resulting in high operating costs and difficulty in changing the liquid type later. Changing the distance and area of ​​the inner and outer steel plates also has the drawback of being unadjustable after use, meaning the damping force of the viscous damping wall is limited and unadjustable.

[0003] Therefore, it is necessary to invent an amplification device for an adjustable viscous damping wall to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an amplification device for an adjustable viscous damping wall to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable viscous damping wall amplification device, comprising a shell, a sliding plate, an upper connecting plate, a first pin, a second pin, and silicone oil. The upper connecting plate is connected to the engineering wall and receives external force to transmit the force to the sliding plate. The first pin is rotatably connected between the protruding part of the connecting plate and the sliding plate. The protruding part of the connecting plate is fixed to the bottom of the upper connecting plate. The sliding plate is provided with a long through hole. The second pin is rotatably disposed in the long through hole and is located below the first pin. The shell stores silicone oil, and the bottom of the sliding plate is immersed in the silicone oil. The upper surface of the silicone oil is the silicone oil liquid level.

[0006] Preferably, the two ends of the second pin are fixedly installed on the inner walls of the front and rear sides of the outer casing.

[0007] In this invention, the upper connecting plate is connected to the engineering wall, receives external force, and transmits it to the damping wall sliding plate.

[0008] Pin 1 connects the upper connecting plate and the sliding plate. Since the upper connecting plate is translational and the sliding plate rotates within the damping wall, a pin can enable the movement of both.

[0009] Pin shaft two, the rotating shaft of the sliding plate. During actual operation, the sliding plate rotates around pin shaft two. A long slot is opened on the sliding plate. Currently, it is used to adjust the height of the sliding plate at any time and ultimately keep the overall height of the damping wall unchanged.

[0010] The outer shell, serving as the container for silicone oil and the sliding space for the sliding plate.

[0011] Silicone oil, serving as the working medium for the damping wall.

[0012] The force applied to the upper connecting plate from the outside is F1. Pin shaft two is the rotating shaft of the sliding plate, and the distance L1 from its center to the top of the upper connecting plate is the lever arm length of F1. F2 is the force that the sliding plate is passively subjected to due to the action of the upper connecting plate, that is, the viscous force. Pin shaft two is the rotating shaft of the sliding plate, and the distance L2 from its center to the middle position where the sliding plate inserts into the silicone oil is the lever arm length of the sliding plate.

[0013] According to the principle of moment balance, F1 * L1 = F2 * L2. Since L1 < L2, so F1 > F2. Therefore, by controlling the length ratio of L1 to L2, the amplification of the viscous force can be effectively achieved and applied to the structure.

[0014] Preferably, two damping increasing parts two are provided on the sliding plate, and two damping increasing parts one are provided on the outer shell. The damping increasing part one corresponds to the damping increasing part two. Two groups of damping increasing parts two are provided on both sides of the sliding plate, and two groups of damping increasing parts one are installed on the outer sides of the outer shell.

[0015] The damping increasing part two on the sliding plate corresponds to the damping increasing part one on the side of the outer shell. The two can increase the damping force of the sliding plate and can be dynamically adjusted according to requirements, replacing the original method that cannot adjust the damping force of the sliding plate subsequently.

[0016] Preferably, a position adaptation part is provided on the inner wall of the outer shell, and the position adaptation part is correspondingly provided between the damping increasing part one and the damping increasing part two.

[0017] Specifically, the position adaptation part is located between the damping increasing part one and the damping increasing part two. When the sliding plate rotates in the outer shell, the position adaptation part moves upward by using the force to push the silicone oil when the sliding plate rotates.

[0018] Preferably, the second damping enhancement portion includes a mounting groove, a strong magnetic block, a second connecting plate, and a buffer pad. The mounting groove is disposed on the side of the sliding plate, the strong magnetic block is disposed in the mounting groove, and the corners of the strong magnetic block are pressed and restricted to the bottom of the mounting groove by the second connecting plate. The second connecting plate is fixed to the bottom of the mounting groove by screws. The mounting groove extends to the outside of the sliding plate, and the buffer pad is sealed at the opening of the mounting groove.

[0019] When the electromagnet is activated, it repels and moves away from the strong magnetic block, which increases the resistance when the sliding plate rotates in the housing to a position close to the electromagnet. The power of the electromagnet can be changed, so the damping force when the sliding plate rotates can be adjusted.

[0020] Preferably, the damping enhancement portion includes an outer box, an electromagnet, and a first connecting plate. The edge of the outer box is connected to the outer surface of the outer shell through the first connecting plate. The electromagnet is disposed inside the outer box and corresponds to the strong magnetic block.

[0021] When a power source is connected to the external wire, the electromagnet can work. Buffer pads are provided on both sides of the sliding plate to reduce wear when the sliding plate rotates in the housing. The buffer pads replace the side of the sliding plate in contact with the inner wall of the housing.

[0022] Preferably, the external box is provided with a power supply control part for supplying power to the electromagnet. The power supply control part includes a controller, an external wire, and an internal wire. The controller is fixed to the bottom of the external box. The controller and the electromagnet are connected through the internal wire. One end of the external wire is connected to the controller, and the other end extends to the bottom of the external box.

[0023] Because the sliding plate rotates around the second pivot, the position of the damping-enhancing part on the side of the sliding plate will change in the height direction. If the position of the electromagnet in the position adaptation part remains unchanged at this time, it is difficult to maintain the corresponding position of the electromagnet and the strong magnetic block to maintain sufficient damping force. Therefore, a sliding groove, a sliding block, a magnetic block, and a moving plate are designed. When the sliding plate rotates to one side of the shell, the hydrodynamic force generated by the silicone oil during rotation will push the inclined moving plate to float upward. At this time, the moving plate drives the magnetic block and the sliding block to rise. When the magnetic block slides upward, the electromagnet is attracted by the magnetic block and rises. At this time, the electromagnet rises to adapt to the rising position of the strong magnetic block on the side of the sliding plate, ensuring that the strong magnetic block and the electromagnet can maintain a corresponding distribution.

[0024] Preferably, the outer box is provided with a guide rod for guiding the electromagnet to rise and fall. The bottom of the guide rod is fixedly welded to the bottom surface of the outer box. The electromagnet is provided with a guide hole for the guide rod to pass through vertically. The outer box is provided with an upper cover.

[0025] The internal connecting wire is reserved with sufficient length to facilitate the sliding up and down of the electromagnet on the guide rod. In order to reduce the friction when the electromagnet moves up and down, measures such as buffer pads can be provided on the corresponding surface of the electromagnet, which are common wear-reducing measures in the prior art and will not be elaborated here.

[0026] Preferably, the position adaptation part includes a sliding groove, a sliding block, a magnetic block, and a moving plate. The sliding groove is arranged on the inner wall of the outer shell. The sliding block is slidably arranged in the sliding groove, and the magnetic block is fixed at the end of the sliding block.

[0027] Among them, the upper cover at the upper end of the external box can be opened to facilitate the disassembly, assembly, and maintenance of the internal structure of the external box. The external box is detachably connected to the outer shell through the first connecting plate, which is convenient for disassembly and maintenance. In the device, the strong magnetic block is fixedly installed on the bottom surface of the installation groove through the second connecting plate, which is convenient for disassembly and maintenance.

[0028] Preferably, the moving plate is fixed at the lower end of the magnetic block. The magnetic block is fixedly attracted to the electromagnet, and the inclined surface of the moving plate faces the direction where the lower end of the magnetic block approaches the strong magnetic block.

[0029] The technical effects and advantages of the present invention are as follows:

[0030] 1. An amplification device for an adjustable viscous damping wall of the present invention includes an outer shell, a sliding plate, an upper connecting plate, a pin shaft one, a pin shaft two, and silicone oil. The upper connecting plate is connected to the engineering wall. The upper connecting plate receives an external force and transmits the force to the sliding plate. The pin shaft one is rotatably connected between the convex part of the connecting plate and the sliding plate. The external force applied to the upper connecting plate is F1. The pin shaft two serves as the rotation axis of the sliding plate, and the distance L1 from its center to the top of the upper connecting plate is the lever arm length of the force F1; F2 is the force that the sliding plate is passively subjected to due to the action of the upper connecting plate, that is, the viscous force. The pin shaft two serves as the rotation axis of the sliding plate, and the distance L2 from its center to the middle position where the sliding plate is inserted into the silicone oil is the lever arm length of the sliding plate. According to the principle of torque balance, F1*L1 = F2*L2. Since L1 < L2, so F1 > F2. Therefore, by controlling the length ratio of L1 to L2, the amplification of the viscous force can be effectively achieved and applied to the structure.

[0031] 2. An amplification device for an adjustable viscous damping wall of the present invention. The damping increase part two on the sliding plate corresponds to the damping increase part one on the side of the outer shell. The two can increase the damping force of the sliding plate and can be dynamically adjusted according to requirements, replacing the original method that cannot adjust the damping force of the sliding plate subsequently.

[0032] 3. An amplification device for an adjustable viscous damping wall according to the present invention, wherein when the electromagnet is activated, the electromagnet and the strong magnetic block repel each other and move away, so that the resistance is increased when the sliding plate rotates in the outer shell to a position close to the electromagnet, and the power of the electromagnet can be changed, so that the damping force when the sliding plate rotates can be adjusted.

[0033] 4. In the amplification device of the adjustable viscous damping wall of the present invention, since the sliding plate rotates around the second pin, the position of the damping increase part on the side of the sliding plate will change in the height direction. If the position of the electromagnet in the position adaptation part does not change at this time, it is difficult to maintain the position correspondence between the electromagnet and the strong magnetic block to maintain sufficient damping force. Therefore, a sliding groove, a sliding block, a magnetic block, and a moving plate are designed. When the sliding plate rotates to one side of the shell, the fluid force generated by the silicone oil during rotation will push the inclined moving plate to float upward. At this time, the moving plate drives the magnetic block and the sliding block to rise. When the magnetic block slides upward, the electromagnet is attracted by the magnetic block and rises. At this time, the electromagnet rises to adapt to the rise of the strong magnetic block on the side of the sliding plate, ensuring that the strong magnetic block and the electromagnet can maintain a corresponding distribution state.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] This invention provides, for example Figure 1-3 An amplification device for an adjustable viscous damping wall is shown, comprising a housing 1, a sliding plate 2, an upper connecting plate 3, a first pin 4, a second pin 5, and silicone oil 8. The upper connecting plate 3 is connected to the engineering wall and receives external force to transmit the force to the sliding plate 2. The first pin 4 is rotatably connected between the protruding part 7 of the connecting plate and the sliding plate 2. The protruding part 7 of the connecting plate is fixed to the bottom of the upper connecting plate 3. The sliding plate 2 is provided with a through-hole 6. The second pin 5 is rotatably disposed in the through-hole 6 and is located below the first pin 4. The housing 1 stores silicone oil 8, and the bottom of the sliding plate 2 is immersed in the silicone oil 8. The upper surface of the silicone oil 8 is the silicone oil surface 9.

[0043] The two ends of the second pin 5 are fixedly installed on the inner walls of the front and rear sides of the outer casing 1.

[0044] In this invention, the upper connecting plate 3 is connected to the engineering wall, receives external force, and transmits it to the damping wall sliding plate 2.

[0045] Pin 4 connects the upper connecting plate 3 and the sliding plate 2. Since the upper connecting plate 3 is translational and the sliding plate 2 rotates within the damping wall, the action of both can be achieved through a pin.

[0046] Pin 2 5 is the pivot for the rotation of sliding plate 2. In actual operation, sliding plate 2 rotates around pin 2 5. A long hole 6 is opened on sliding plate 2, which is currently used to adjust the height of sliding plate 2 at any time and ultimately keep the overall height of the damping wall constant.

[0047] The outer shell 1 serves as a container for the silicone oil 8 and a sliding space for the sliding plate 2;

[0048] Silicone oil 8 serves as the working medium for damping wall action.

[0049] The external force applied to the upper connecting plate 3 is F1. The second pin 5 serves as the pivot for the rotation of the sliding plate 2. The distance L1 from its center to the top of the upper connecting plate 3 is the lever arm length of F1. F2 is the passive force and viscous force on the sliding plate 2 due to the action of the upper connecting plate 3. The distance L2 from the center of the second pin 5 to the middle position of the sliding plate 2 inserted into the silicone oil 8 is the lever arm length of the sliding plate 2.

[0050] According to the principle of torque balance, F1*L1 = F2*L2. Since L1 < L2, then F1 > F2. Therefore, by controlling the length ratio of L1 to L2, the amplification of viscous force can be effectively achieved and applied to the structure.

[0051] In Embodiment 2

[0052] The present invention provides an amplification device for an adjustable viscous damping wall as shown in Figure 1-6 It includes a housing 1, a sliding plate 2, an upper connecting plate 3, a pin 1 4, a pin 2 5, and silicone oil 8. The upper connecting plate 3 is connected to the engineering wall. The upper connecting plate 3 receives an external force and transmits the force to the sliding plate 2. The pin 1 4 is rotatably connected between the convex part 7 of the connecting plate and the sliding plate 2. The convex part 7 of the connecting plate is fixed to the bottom of the upper connecting plate 3. A long hole 6 penetrating through the front and back is provided on the sliding plate 2. The pin 2 5 is rotatably arranged in the long hole 6. The pin 2 5 is arranged below the pin 1 4. The housing 1 stores the silicone oil 8. The bottom of the sliding plate 2 is immersed in the silicone oil 8. The upper surface of the silicone oil 8 is the silicone oil liquid surface 9.

[0053] Both ends of the pin 2 5 are fixedly installed on the inner walls of the front and back sides of the housing 1.

[0054] In the present invention, the upper connecting plate 3 is connected to the engineering wall, receives an external force, and transmits it to the damping wall sliding plate 2 through it;

[0055] The pin 1 4 realizes the connection between the upper connecting plate 3 and the sliding plate 2. Since the upper connecting plate 3 moves linearly and the sliding plate 2 rotates in the damping wall, the actions of both can be realized through one pin;

[0056] The pin 2 5 is the rotating shaft of the sliding plate 2. The sliding plate 2 rotates around the pin 2 5 during actual operation; A long hole 6 is opened on the sliding plate 2. Currently, it is to adjust the height of the sliding plate 2 at any time and finally keep the overall height of the damping wall unchanged;

[0057] The housing 1 serves as a container for the silicone oil 8 and a sliding space for the sliding plate 2;

[0058] The silicone oil 8 serves as the working medium for the damping wall to function.

[0059] The external force applied to the upper connecting plate 3 is F1. The pin 2 5 is the rotating shaft of the sliding plate 2. The distance L1 from its center to the top of the upper connecting plate 3 is the lever arm length of F1; F2 is the force that the sliding plate 2 is passively subjected to due to the action of the upper connecting plate 3, that is, the viscous force; The pin 2 5 is the rotating shaft of the sliding plate 2. The distance L2 from its center to the middle position where the sliding plate 2 is inserted into the silicone oil 8 is the lever arm length of the sliding plate 2.

[0060] According to the principle of torque balance, F1*L1 = F2*L2. Since L1 < L2, then F1 > F2. Therefore, by controlling the length ratio of L1 to L2, the amplification of viscous force can be effectively achieved and applied to the structure.

[0061] A damping increase part two 11 is provided on the sliding plate 2, and a damping increase part one 10 is provided on the outer shell 1. The damping increase part one 10 corresponds to the damping increase part two 11. There are two groups of the damping increase part two 11, and the two groups of the damping increase part two 11 are arranged on both sides of the sliding plate 2. There are two groups of the damping increase part one 10, and the two groups of the damping increase part one 10 are installed on the outer sides of the outer shell 1.

[0062] The damping increase part two 11 on the sliding plate 2 corresponds to the damping increase part one 10 on the side of the outer shell 1. The two can achieve the effect of increasing the damping force of the sliding plate 2 and can be dynamically adjusted according to requirements, replacing the original method that cannot adjust the damping force of the sliding plate 2 subsequently.

[0063] A position adaptation part 12 is provided on the inner wall of the outer shell 1, and the position adaptation part 12 is correspondingly provided between the damping increase part one 10 and the damping increase part two 11.

[0064] Specifically, the position adaptation part 12 is located between the damping increase part one 10 and the damping increase part two 11. When the sliding plate 2 rotates in the outer shell 1, when the sliding plate 2 rotates, the force used to push the silicone oil 8 causes the position adaptation part 12 to move upward.

[0065] The damping increase part two 11 includes an installation groove 24, a strong magnetic block 25, a second connecting plate 26, and a buffer backing plate 27. The installation groove 24 is provided on the side of the sliding plate 2, the strong magnetic block 25 is provided in the installation groove 24, the corners of the strong magnetic block 25 are pressed and restricted at the bottom of the installation groove 24 through the second connecting plate 26, the second connecting plate 26 and the bottom of the installation groove 24 are fixed by screws, the installation groove 24 penetrates to the outside of the sliding plate 2, and the buffer backing plate 27 is sealed at the opening of the installation groove 24.

[0066] When the electromagnet 21 is activated, the electromagnet 21 repels and moves away from the strong magnetic block 25, so that when the sliding plate 2 rotates in the outer shell 1 to a position close to the electromagnet 21, the resistance is increased, and the power of the electromagnet 21 can be changed, so that the damping force when the sliding plate 2 rotates is adjustable.

[0067] The damping increase part one 10 includes an external box 17, an electromagnet 21, and a first connecting plate 18. The edge of the external box 17 is connected to the outer surface of the outer shell 1 through the first connecting plate 18, the electromagnet 21 is provided inside the external box 17, and the electromagnet 21 corresponds to the strong magnetic block 25.

[0068] When a power source is connected to the external wire 28, the electromagnet 21 can work. Buffer pads 27 are provided on both sides of the sliding plate 2 to reduce wear when the sliding plate 2 rotates in the outer casing 1. The buffer pads 27 replace the side of the sliding plate 2 in contact with the inner wall of the outer casing 1.

[0069] The external box 17 is equipped with a power supply control part for supplying power to the electromagnet 21. The power supply control part includes a controller 22, an external wire 28, and an internal wire 23. The controller 22 is fixed to the bottom of the external box 17. The controller 22 and the electromagnet 21 are connected through the internal wire 23. One end of the external wire 28 is connected to the controller 22, and the other end extends to the bottom of the external box 17.

[0070] Because the sliding plate 2 rotates around the pin 2 5, the position of the damping increase part 2 11 on the side of the sliding plate 2 will change in the height direction. If the position of the electromagnet 21 in the position adaptation part 12 remains unchanged at this time, it is difficult to maintain the position correspondence between the electromagnet 21 and the strong magnetic block 25 to maintain sufficient damping force. Therefore, a sliding groove 13, a sliding block 14, a magnetic block 15, and a moving plate 16 are designed. When the sliding plate 2 rotates to one side of the outer shell 1, the hydrodynamic force generated by the silicone oil 8 during rotation will push the inclined moving plate 16 to float upward. At this time, the moving plate 16 drives the magnetic block 15 and the sliding block 14 to rise. When the magnetic block 15 slides upward, the electromagnet 21 is attracted by the magnetic block 15 and rises. At this time, the electromagnet 21 rises to adapt to the rising position of the strong magnetic block 25 on the side of the sliding plate 2, ensuring that the strong magnetic block 25 and the electromagnet 21 can maintain a corresponding distribution.

[0071] The outer box 17 is provided with a guide rod 19 for guiding the electromagnet 21 to rise and fall. The bottom of the guide rod 19 is fixedly welded to the bottom surface of the outer box 17. The electromagnet 21 is provided with a guide hole 20 for the guide rod 19 to pass through vertically. The outer box 17 is provided with an upper cover 29.

[0072] The internal wire 23 is reserved with sufficient length to facilitate the sliding and lifting of the electromagnet 21 on the guide rod 19. In order to reduce the friction when the electromagnet 21 is raised and lowered, buffer pads or other measures can be provided on the corresponding surface of the electromagnet 21. These are common wear-reducing measures and will not be described in detail here.

[0073] The position adaptation part 12 includes a sliding groove 13, a sliding block 14, a magnetic block 15, and a moving plate 16. The sliding groove 13 is disposed on the inner wall of the outer casing 1, the sliding block 14 is slidably disposed in the sliding groove 13, and the magnetic block 15 is fixed to the end of the sliding block 14.

[0074] The upper cover 29 of the outer box 17 can be opened to facilitate the disassembly and maintenance of the internal structure of the outer box 17. The outer box 17 is detachably connected to the outer shell 1 through the first connecting plate 18, which facilitates disassembly and maintenance. In the device, the strong magnetic block 25 is fixedly installed on the bottom surface of the mounting groove 24 through the second connecting plate 26, which facilitates disassembly and maintenance.

[0075] The movable plate 16 is fixed to the lower end of the magnetic block 15. The magnetic block 15 and the electromagnet 21 are attracted and fixed together. The inclined surface of the movable plate 16 faces the lower end of the magnetic block 15 and is close to the strong magnetic block 25.

[0076] Working principle: When electromagnet 21 is activated, electromagnet 21 and strong magnetic block 25 repel each other and move away, so that when sliding plate 2 rotates in the outer shell 1 to a position close to electromagnet 21, the resistance is increased. The power of electromagnet 21 can be changed, so the damping force when sliding plate 2 rotates can be adjusted.

[0077] When a power source is connected to the external wire 28, the electromagnet 21 can work. Buffer pads 27 are provided on both sides of the sliding plate 2 to reduce wear when the sliding plate 2 rotates in the outer casing 1. The buffer pads 27 replace the side of the sliding plate 2 in contact with the inner wall of the outer casing 1.

[0078] Because the sliding plate 2 rotates around the pin 2 5, the position of the damping increase part 2 11 on the side of the sliding plate 2 will change in the height direction. If the position of the electromagnet 21 in the position adaptation part 12 remains unchanged at this time, it is difficult to maintain the position correspondence between the electromagnet 21 and the strong magnetic block 25 to maintain sufficient damping force. Therefore, a sliding groove 13, a sliding block 14, a magnetic block 15, and a moving plate 16 are designed. When the sliding plate 2 rotates to one side of the outer shell 1, the hydrodynamic force generated by the silicone oil 8 during rotation will push the inclined moving plate 16 to float upward. At this time, the moving plate 16 drives the magnetic block 15 and the sliding block 14 to rise. When the magnetic block 15 slides upward, the electromagnet 21 is attracted by the magnetic block 15 and rises. At this time, the electromagnet 21 rises to adapt to the rising position of the strong magnetic block 25 on the side of the sliding plate 2, ensuring that the strong magnetic block 25 and the electromagnet 21 can maintain a corresponding distribution.
