Detailed Embodiments

[0017] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] As Figures 1-8 shown, a viscous damper testing device includes a bottom plate 1. One side of the upper end of the bottom plate 1 is connected with a support plate 2, which is convenient for connecting one of the arc-shaped plates 9 and the electric slide rail 10. Four groups of slide rods 3 are evenly connected to one side of the support plate 2. The number of slide rods 3 is four groups. One side of the upper end of the bottom plate 1 far from one side of the upper end of the support plate 2 is connected with a connecting plate 4, which can fix the hydraulic cylinder 5. The middle part of one side of the connecting plate 4 is connected with a hydraulic cylinder 5. One end of the hydraulic cylinder 5 penetrates and extends to one side of the connecting plate 4. One end of the hydraulic cylinder 5 is connected with a sliding plate 6, which can connect the other arc-shaped plate 9 and the electric slide rail 10. Adjusting components are connected to both the sliding plate 6 and one side of the support plate 2. The sliding plate 6 slides along the outer walls of multiple slide rods 3 respectively. Openings are formed at the positions where the sliding plate 6 corresponds to multiple slide rods 3 respectively. Multiple slide rods 3 are respectively located inside multiple openings. One side of the upper end of the bottom plate 1 is connected with a connecting slide rail 7 to improve the stability of the sliding plate 6 during movement. The lower end of the sliding plate 6 slides above the connecting slide rail 7; The four groups of slide rods 3 are evenly distributed to form a stable guiding structure, providing accurate guidance for the movement of the sliding plate 6, reducing the shaking and deviation during the movement. The matching design of the connecting slide rail 7 and the lower end of the sliding plate 6 further enhances the stability of the sliding plate 6 during movement, enabling it to move smoothly and accurately under the drive of the hydraulic cylinder 5, ensuring the reliability of the testing process. The adjusting component can adjust the angular position of the slider 11.

[0019] The adjusting component includes mounting blocks 8. There are two groups of adjusting components. One side of two of the mounting blocks 8 is connected to one side of the sliding plate 6, and one side of the other two mounting blocks 8 is connected to one side of the support plate 2, which can fix the arc-shaped plate 9 to one side of the sliding plate 6 and one side of the support plate 2. The number of mounting blocks 8 is two groups. One side of the two mounting blocks 8 is connected with an arc-shaped plate 9. The middle part of one side of the arc-shaped plate 9 is connected with an electric slide rail 10, which can drive the slider 11 to slide on the outer wall of the electric slide rail 10. The shape of the electric slide rail 10 is set in a semi-circular arc structure. One side of the outer wall of the electric slide rail 10 is slidably connected with a slider 11. One side of the slider 11 is connected with a mounting component. A damper body 29 is connected between the two mounting components. Stable components are circumferentially connected to the outer walls of the two arc-shaped plates 9. Multiple stable components are respectively distributed at the upper end, lower end and one side of the outer wall of the arc-shaped plate 9; The two sets of adjustment components are symmetrically arranged, ensuring the symmetry and stability of the installation of the arc-shaped plate 9. The semi-arc design of the arc-shaped plate 9 is adapted to the electric slide rail 10, which can provide a stable arc-shaped movement track for the slider 11. The electric slide rail 10 can ensure that the slider 11 can slide smoothly and accurately on its outer wall, so as to realize the precise adjustment of the angle and position of the damper body 29. The stabilizing components are evenly distributed on the outer wall of the arc-shaped plate 9, which can limit and support the slider 11 from multiple directions, effectively improving the stability of the entire test device during operation and ensuring the accuracy of the test results.

[0020] The installation component includes an installation base 12. Both ends of the damper body 29 are inserted into the inner walls of the two installation bases 12. One end of the installation base 12 is connected to one side of the slider 11. In the middle of one side of the installation base 12, a fixed cylinder 13 is connected. In the middle of one side of the fixed cylinder 13, a cylinder 14 is connected, which can push the motor 15 and the bolt 16 to move inside the installation base 12. One end of the cylinder 14 penetrates and extends into the fixed cylinder 13. One end of the cylinder 14 is connected to a motor 15, which can drive the bolt 16 to rotate 90 degrees. The output end of the motor 15 is connected to the bolt 16. One end of the bolt 16 penetrates and extends into the installation base 12. Card slots 28 are opened on both sides of the slider 11. The side of the installation base 12 away from the fixed cylinder 13 is connected to a connecting cylinder 17, which can connect one end of the bolt 16. In the middle of one side of the inner wall of the connecting cylinder 17, a clamping cylinder 18 is connected. A connecting groove is opened on one side of the clamping cylinder 18. One end of the bolt 16 is inserted into the connecting cylinder 17. The clamping block 19 and the two stopper blocks 20 are inserted into the clamping cylinder 18 through the connecting groove. Then, the motor 15 drives the bolt 16, the clamping block 19 and the two stopper blocks 20 to rotate 90 degrees. In the middle of one side of the bolt 16, a clamping block 19 is connected. Both sides of the clamping block 19 are connected to stopper blocks 20. After rotating 90 degrees, the two stopper blocks 20 are clamped into the clamping cylinder 18, and one end of the clamping block 19 and one end of the two stopper blocks 20 are both inserted into the clamping cylinder 18; The installation base 12 can ensure that the damper body 29 can be inserted accurately and stably. The fixed cylinder 13 and the connecting cylinder 17 provide a stable installation and movement space for the cylinder 14 and the bolt 16. The cylinder 14 can quickly and accurately push the motor 15 and the bolt 16 to move. The coordinated design of the motor 15 and the bolt 16 ensures that the bolt 16 can rotate 90 degrees accurately, realizing the reliable clamping of the clamping block 19 and the stopper blocks 20 with the clamping cylinder 18, thereby firmly fixing the damper body 29 on the installation base 12, ensuring that the damper body 29 will not loosen or displace during the test, and ensuring the safety and accuracy of the test.

[0021] The stabilizing component includes a frame body 21. The shape of the frame body 21 corresponding to one side of the arc-shaped plate 9 is arranged in an arc structure. One side of the frame body 21 is connected to the outer wall of the arc-shaped plate 9. Installation plates 22 are evenly connected to the inner wall of the arc-shaped plate 9 corresponding to one side of the frame body 21. The installation plates 22 can guide when the insertion blocks 26 move. The number of the installation plates 22 is two groups. One side of the inner wall of the frame body 21 is connected with a double-shaft electric telescopic rod 23, which drives two moving blocks 24 to move inside the frame body 21. Both ends of the double-shaft electric telescopic rod 23 are connected with moving blocks 24. One end of each of the two moving blocks 24 penetrates and extends to one side of the frame body 21. Chute grooves 27 are respectively opened at the positions of the frame body 21 corresponding to the two moving blocks 24 to ensure the stability performance when the moving blocks 24 move. The two moving blocks 24 slide inside the two chute grooves 27 respectively. The two moving blocks 24 are respectively located on both sides of the arc-shaped plate 9. Stabilizing rods 25 are connected to one side of the inner wall of the frame body 21. The two moving blocks 24 slide on the outer walls of the plurality of stabilizing rods 25 respectively. One side of each of the two moving blocks 24 is connected with an insertion block 26. When the slider 11 moves to the position corresponding to the frame body 21, the double-shaft electric telescopic rod 23 drives the two moving blocks 24 to move, and then can push the two insertion blocks 26 to be inserted into the two card slots 28, so as to limit the position of the slider 11 and ensure the stability performance of the slider 11 during the test. One end of each of the two insertion blocks 26 penetrates and extends to one side of the two installation plates 22 respectively. One end of each of the two insertion blocks 26 is clamped into the two card slots 28 respectively; The arc structure of the frame body 21 fits perfectly with the arc-shaped plate 9. The installation plates 22 provide precise guidance for the movement of the insertion blocks 26, ensuring that the insertion blocks 26 can accurately insert into the card slots 28 of the slider 11. The double-shaft electric telescopic rod 23 has high-precision displacement control ability and can quickly and stably drive the two moving blocks 24 to move inside the frame body 21. The chute grooves 27 and the stabilizing rods 25 provide double stability guarantees for the movement of the moving blocks 24, reducing the shaking and friction during the movement. When the slider 11 reaches the predetermined position, the double-shaft electric telescopic rod 23 quickly pushes the insertion blocks 26 into the card slots 28 to realize the quick and reliable limitation of the slider 11, effectively preventing the slider 11 from generating displacement due to force during the test and ensuring the stability of the whole test process and the reliability of the test results.

[0022] Working principle: Before the test starts, insert both ends of the damper body 29 into the inner wall of the mounting seat 12. Start the cylinder 14 in the mounting assembly, and push the motor 15 and the bolt 16 to move inside the mounting seat 12, so that one end of the bolt 16 is inserted into the clamping cylinder 18 inside the connecting cylinder 17. Subsequently, the motor 15 drives the bolt 16, the clamping block 19 and the stop block 20 to rotate, so that the stop block 20 is clamped with the inner wall of the clamping cylinder 18, completing the installation of both ends of the damper body 29. Then, the electric slide rail 10 drives the slider 11 to slide along a semi-circular track to adjust the angle and position of the damper body 29. When the slider 11 reaches the predetermined position, the stabilizing assembly starts to work. The double-axis electric telescopic rod 23 pushes the moving block 24 to slide along the stabilizing rod 25, so that the insertion block 26 is inserted into the card slots 28 on both sides of the slider 11, thereby realizing the precise positioning and support of the position of the slider 11; The hydraulic cylinder 5 is started, and it pushes the sliding plate 6 to perform a horizontal reciprocating motion along the sliding rod 3 and the connecting slide rail 7. The sliding rod 3 and the connecting slide rail 7 jointly limit the movement track of the sliding plate 6 to ensure the accuracy of the loading direction. While performing the horizontal loading, the electric slide rail 10 drives the slider 11 to slide along an arc path; During the whole test process, when the slider 11 moves to the corresponding stabilizing assembly, the stabilizing assembly continuously plays a role. Through the cooperation of the insertion block 26 and the card slot 28, the position of the slider 11 is locked in real time to prevent displacement deviation of the slider 11 caused by the change of the damping force. The arc design of the frame body 21 and the guiding function of the mounting plate 22 ensure that the insertion block 26 can be accurately inserted, ensuring the stable performance of the damper body 29 during the test. The damper body 29 can be tested at multiple angles. Through the coordinated control of the actions of the hydraulic cylinder 5 and the connecting slide rail 7, the actual stress state of the damper body 29 under various complex working conditions such as earthquakes and wind vibrations can be simulated, and then the test can be carried out.
