Description

Technical Field

[0001] This invention relates to the field of civil engineering structural technology, specifically to a series viscous damper. Background Technology

[0002] Damping walls for buildings are safety devices installed on buildings to mitigate earthquake damage. They are widely used in civil buildings, industrial buildings, and bridges. When an earthquake occurs, damping walls absorb and dissipate the impact energy of the earthquake on the building structure to the maximum extent, greatly mitigating the impact and damage of the earthquake on the building structure.

[0003] However, the existing installation of building dampers still has many defects. For example, the existing viscous damper wall installation requires one damper per wall, which greatly increases the installation cost.

[0004] Therefore, since it does not meet the existing requirements, we propose a series viscous damper. Summary of the Invention

[0036] Example 1;

[0037] Reference Figures 1-12 A series viscous damper includes a damper 1 installed between two walls, namely wall one and wall two. The damper 1 includes a damper body 101. The output end of the damper body 101 is connected to a pin 102, and the other end is connected to a pin 2 103. The pin 102 is rotatably connected to an ear plate 2, and the pin 2 103 is rotatably connected to an ear plate 3 or a series plate. There are two dampers 1, namely a first damper and a second damper. The two dampers 1 can be combined and installed in various ways.

[0038] Specifically as follows:

[0039] 1. The output end of damper 1 is rotatably connected to ear plate 2, which is fixedly connected to wall 1. The other end is rotatably connected to ear plate 3, which is fixedly connected to wall 2. The two dampers 1 are arranged in a horizontal array, as shown below. Figure 1 As shown;

[0040] II. A series plate is fixedly installed on wall II. Both ends of the series plate are rotatably connected to pins 103 at the non-output ends of two dampers 1. Ear plates 2, rotatably connected to pins 102 at the output ends of the two dampers 1, are fixed to both sides of wall I. Figure 2 As shown;

[0041] 3. The output end of damper 1 is rotatably connected to ear plate 2, which is fixedly connected to wall 1. The other end is rotatably connected to ear plate 3, which is fixedly connected to wall 2. The two dampers 1 are mirror images of each other. Figure 3 As shown;

[0042] IV. A series plate is fixedly installed on wall 1. Both ends of the series plate are rotatably connected to pins 103 at the non-output ends of two dampers 1. Ear plates 2, rotatably connected to pins 102 at the output ends of the two dampers 1, are fixed to both sides of wall 2. Figure 4 As shown;

[0043] 5. The output end of damper 1 is rotatably connected to ear plate 2, which is fixedly connected to wall 2. The other end is rotatably connected to ear plate 3, which is fixedly connected to wall 1. The two dampers 1 are arranged in a horizontal array, as shown below. Figure 5 As shown;

[0044] VI. In the two dampers 1: the output end of the first damper is rotatably connected to the lug 1 2, which is fixedly connected to wall 1, and the other end is rotatably connected to the lug 2 3, which is fixedly connected to wall 2; the output end of the second damper is rotatably connected to the lug 1 2, which is rotatably connected to wall 2, and the other end is rotatably connected to the lug 2 3, which is fixedly connected to wall 1, as follows. Figure 6 As shown.

[0045] Example 2:

[0046] Similar to Example 1, the technical problem with the above solution is that the small-sized damper 1 easily reaches its maximum stroke under strong earthquakes, losing its energy dissipation capacity. Therefore, a further step is to refer to... Figures 7-12 A series viscous damper, wherein a stroke extension mechanism 5 is provided between the end of the pin 103 away from the damper body 101 and the ear plate 3;

[0047] The stroke extension mechanism 5 includes: transverse grooves 502 formed on both sides of the ear plate 2 3; a connecting block 9 fixedly connected to the pin head 2 103; a cylindrical shaft 501 fixedly connected to both sides of the connecting block 9; the outer wall of the cylindrical shaft 501 slidably connected to the inner wall of the transverse groove 502; a slider 503 rotatably connected to the outer wall of the cylindrical shaft 501; guide grooves 504 formed at the top and bottom of the slider 503; guide rails 505 fixedly connected to the top and bottom of the inner wall of the transverse groove 502; and the outer wall of the guide rail 505 slidably connected to the inner wall of the guide groove 504. Through the sliding cooperation between the cylindrical shaft 501 and the transverse groove 502, a basic displacement transmission path is formed, and the movement of the slider 503 is guided by the sliding connection between the top and bottom guide grooves 504 and the guide rails 505.

[0048] A connecting rod 507 is fixedly connected to the outer side of the slider 503. A sliding hole 508 is provided on the side wall of the transverse groove 502. The inner wall of the sliding hole 508 is slidably connected to the outer wall of the connecting rod 507. A disc spring 506 is stacked on the outer wall of the connecting rod 507. The disc spring 506 absorbs the initial impact kinetic energy under pressure deformation, provides the first-level buffer, and suppresses the peak load.

[0049] In use: The relative movement of the wall pushes the damper body 101 to extend and retract → drives the pin head 103 to move → the cylindrical shaft 501 of the connecting block 9 slides laterally along the transverse groove 502 of the ear plate 3; when the cylindrical shaft 501 slides, it compresses the disc spring 506 through the slider 503.

[0050] The connecting block 9 has a vertical through groove 601. A fixed shaft 602 is fixedly installed on the inner wall of the groove 601. The fixed shaft 602 is coaxial with the cylindrical shaft 501. An adjusting rod 603 is provided on the inner side of the ear plate 2 3. A circular sleeve 605 is fixedly connected to the bottom end of the adjusting rod 603. A rotating shaft 606 is rotatably connected to the inner wall of the circular sleeve 605. Both ends of the rotating shaft 606 are fixedly connected to the inner side of the ear plate 2 3.

[0051] A vertical groove 604 is provided on the adjusting rod 603. The inner wall of the vertical groove 604 is slidably connected to the outer wall of the fixed shaft 602. A damping pad 701 is installed on the inner wall of the vertical groove 604.

[0052] A support frame 801 is fixedly installed on the right side of the ear plate 2 3. A support frame 804 is rotatably connected to the middle of the support frame 801. A fixing plate 703 is installed on the inner side of the support frame 804. A thrust spring 702 is fixedly installed on the inner side of the fixing plate 703. The end of the thrust spring 702 away from the fixing plate 703 is fixedly connected to the outer side of the adjusting rod 603.

[0053] In use: the fixed shaft 602 slides along the vertical groove 604, converting linear displacement into rotational displacement of the adjusting rod 603; through the lever ratio design (inclination control of the vertical groove 604), displacement amplification is achieved, breaking through the stroke limit of the small damper; the circular sleeve 605 provides a covering support for the rotating shaft 606, eliminating stress concentration at the root;

[0054] A hydraulic rod 2 803 is fixedly installed on the inner side of the support frame 804. The output end of the hydraulic rod 2 803 is fixedly connected to the fixed plate 703. A hydraulic rod 1 802 is fixedly installed on the support frame 801. The output end of the hydraulic rod 1 802 is fixedly connected to the connecting rod 507.

[0055] The oil chamber of hydraulic rod 1 (802) is connected to the oil chamber of hydraulic rod 2 (803);

[0056] In use: Hydraulic rod 1 802 and hydraulic rod 2 803 are directly connected in the oil circuit to form a force closed-loop system: displacement of cylindrical shaft 501 → hydraulic pressure → compression of thrust spring 702 → rotational resistance of adjusting rod 603; rotation angle of adjusting rod 603 → reaction force → sliding resistance of cylindrical shaft 501; achieving bidirectional adaptive resistance enhancement;

[0057] The inner wall of the circular sleeve 605 has a cylindrical groove 607, and a torsion spring rotary damper 608 is installed on the inner wall of the cylindrical groove 607. The inner wall of the torsion spring rotary damper 608 is fixedly connected to the rotating shaft 606, and the outer wall of the torsion spring rotary damper 608 is fixedly connected to the inner wall of the cylindrical groove 607. In use: a viscous damping torque is generated synchronously when the adjusting rod 603 rotates; an integrated torsion spring energy storage element is used to drive the mechanism to accurately reset when the earthquake input weakens.

[0058] A through groove 807 is provided on the hydraulic rod 803. A guide shaft 805 is slidably connected to the inner wall of the through groove 807. The left end of the guide shaft 805 is rotatably connected to the outer wall of the adjusting rod 603. In use, the sliding fit between the guide shaft 805 and the through groove 807 eliminates rotational motion interference and ensures smooth operation throughout the entire stroke.

[0059] Working principle: During the earthquake input stage: The relative motion of the wall pushes the damper body 101 to extend and retract → driving the pin head 103 to move → the cylindrical shaft 501 of the connecting block 9 slides laterally along the transverse groove 502 of the ear plate 3; when the cylindrical shaft 501 slides, it compresses the disc spring 506 (first-stage buffer) through the slider 503, and at the same time pushes the connecting rod 507 to drive the hydraulic rod 802 piston to move;

[0060] Hydraulic linkage stage: The oil pressure of hydraulic rod 1 802 is transmitted to hydraulic rod 2 803 through the pipeline → pushing the fixed plate 703 to move → compressing the thrust spring 702 (second stage elastic energy storage); the thrust spring 702 pushes the adjusting rod 603 to rotate around the rotating shaft 606 (lever amplification effect).

[0061] During the stroke extension stage: When the adjusting rod 603 rotates, its vertical groove 604 slides relative to the fixed shaft 602 of the connecting block 9, converting linear displacement into rotational displacement (key stroke amplification point); at the same time, the torsion spring rotation damper 608 provides resistance torque (energy dissipation) and stores reset torque when the adjusting rod rotates.
