Description

Technical Field

[0001] This invention relates to the field of building vibration monitoring, and specifically to a horizontal displacement amplification device. Background Technology

[0002] In recent years, with the rapid development of high-rise buildings, issues such as seismic vibration and wind-induced vibration have received widespread attention and research. Passive control technologies such as energy dissipation and vibration reduction have been widely used to reduce the vibration response of high-rise buildings under earthquake and wind action. Shear dampers are devices that use shear deformation to dissipate energy. Common types include shear metal dampers and viscous dampers. They are displacement-dependent dampers and are mainly used to reduce seismic response.

[0003] A horizontal displacement amplification device, application number CN201710858653.7, includes a box girder segment, a gear set, a gear shaft, a hinge shaft support, high-strength bolts, an upper rack plate, a lower rack plate, and a shear damper. The gear set amplifies the horizontal displacement of the structure several times and transmits it to the damper, enabling the shear damper to achieve excellent energy dissipation and vibration reduction effects. It is suitable for seismic design of structures such as shear walls and frame-tube structures with small inter-story displacement. To expand its application range, the shear damper can be designed for minor earthquakes or wind-induced vibrations, and the box girder segment can be designed as a two-stage energy dissipation unit to resist rare earthquakes.

[0004] A method and device for monitoring the condition of building vibration damping devices, with application number CN202211381533.X, belongs to the field of testing technology for static or dynamic balance of machine or structural components. The method receives a vibration damping trigger signal from an environmental monitoring device and determines the vibration damping device group to be tested corresponding to the vibration damping trigger signal; then, based on the vibration damping trigger signal and the vibration damping device group to be tested, it matches the corresponding set of sound comparison curves.

[0005] However, in the existing technology, regular manual inspections of the seismic resistance of buildings, such as the horizontal displacement between the upper and lower parts of the building at the isolation joint, require human resources and waste a lot of manpower. Moreover, slight changes in horizontal displacement are not easily detected by the inspection personnel. Summary of the Invention

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] This invention provides a horizontal displacement amplification device, comprising a lower support and an upper support arranged from bottom to top, with an isolation gap between the lower support and the upper support. A universal support structure is fixedly installed on the lower support and the upper support near the isolation gap, with the two universal support structures distributed vertically on both sides of the isolation gap.

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0038] See Figure 1-8As shown, this invention provides a horizontal displacement amplification device, comprising a lower support 1 and an upper support 2 arranged from bottom to top. In practical applications, it is applicable not only to columnar building structures composed of the lower support 1 and the upper support 2, but also to upper and lower wall building structures. It is used to amplify and detect the horizontal displacement between upper and lower building structures at an isolation joint. An isolation joint is formed between the lower support 1 and the upper support 2. In practical applications, rubber shock-absorbing supports can also be installed inside the isolation joint. Universal rod support structures 5 are fixedly installed on the side of the lower support 1 and the upper support 2 near the isolation joint. Structure 5 is distributed on both sides of the isolation joint along the vertical direction. A horizontal displacement amplifying rod structure 7 is rotatably installed between the two rod universal support structures 5. An elastic deformation structure for resisting the vertical displacement deformation of the lower support 1 and the upper support 2 is installed on the horizontal displacement amplifying rod structure 7 located between the two rod universal support structures 5. Displacement monitoring and display components 3 for monitoring and displaying the horizontal displacement between the lower support 1 and the upper support 2 are installed at the upper and lower ends of the horizontal displacement amplifying rod structure 7. A damping component 6 for damping and buffering the horizontal displacement of the upper support 2 is installed on the lower support 1.

[0039] See instruction manual attached Figure 5 and 7 As shown, the universal support structure 5 of the pole body includes a second mounting collar 501. The second mounting collars 501 of the two universal support structures 5 are respectively fixedly mounted on the lower support 1 and the upper support 2. One side of the second mounting collar 501 is fixedly connected to the mounting plate 502 by bolts. Each universal support structure 5 of the pole body also includes a first support 503 and a second support 504. The first support 503 and the second support 504 are fixedly connected to each other by connecting bolts 507. The side of the first support 503 and the second support 504 that is close to each other forms a universal ball groove 505. The side of the first support 503 that is away from the second support 504 is fixedly connected to the mounting plate 502. The universal ball groove 505 has openings on the upper and lower sides, and the upper opening has a conical rotating opening groove 506. The tip of the conical rotating opening groove 506 faces the inside of the universal ball groove 505. Through the above-mentioned specific structural design, the first support base 503 and the second support base 504 adopt a two-half design. The combination and cooperation between the first support base 503 and the second support base 504 realizes the combination and cooperation of the universal ball groove 505, which is used to realize the rotational support of the universal rotating ball 702. When the lower support 1 and the upper support column 2 undergo displacement changes in any horizontal direction, the universal rotating ball 702 can make horizontal displacement changes in any direction within the universal ball groove 505. Moreover, the conical rotating opening groove 506 can provide an angle change range for the angle rotation of the displacement amplifying rod 701. Furthermore, the installation and disassembly of the first support base 503 and the second support base 504 can also realize the inspection and replacement of the horizontal displacement amplifying rod structure 7.

[0040] See instruction manual attached Figure 5 and 7 As shown, the horizontal displacement amplifying rod structure 7 includes two omnidirectional rotating balls 702. The two omnidirectional rotating balls 702 rotate into the omnidirectional ball grooves 505 of the two rod universal support base structures 5, respectively. An elastic deformation structure is set between the two omnidirectional rotating balls 702. Displacement amplifying rods 701 are fixedly connected to the sides of the two omnidirectional rotating balls 702 that are far apart from each other. The two displacement amplifying rods 701 share a common central axis. The length of the displacement amplifying rod 701 is more than three times the length of the distance between the centers of the two omnidirectional rotating balls 702. The elastic deformation structure includes two support rods 703, which are fixedly connected to two universal rotating balls 702. The support rods 703 and the displacement amplification rod 701 share a common central axis, and the central axis passes through the center of the universal rotating ball 702. Limiting shoulder plates 704 are fixedly provided on the outer side of the two support rods 703 near one end. A support spring 706 is fixedly connected between the two limiting shoulder plates 704. When the vertical displacement between the lower support 1 and the upper support 2 is zero, the support spring 706 is in a compressed state. In applications where displacement occurs in any direction between the lower support 1 and the upper support 2, the elastic deformation structure is used to amplify the horizontal displacement. When the distance between the two universal rotating spheres 702 changes, the elastic deformation structure undergoes elastic deformation to adapt to this change and provide support. When the horizontal displacement of the lower support 1 and the upper support 2 changes, it drives the two displacement amplification rods 701 to rotate a certain angle within the universal ball groove 505 through the universal rotating spheres 702, thereby realizing the change of horizontal displacement.

[0041] The displacement monitoring and display assembly 3 includes a monitoring display panel 309. One side of each of the two monitoring display panels 309 is fixedly mounted on the lower support 1 and the upper support 2 via a first mounting collar 307. A circular display slot is provided on the monitoring display panel 309. A side light-transmitting area plate 305 is fixedly installed inside the display slot. A central light-blocking area plate 306 is provided at the center of the side light-transmitting area plate 305.

[0042] The displacement monitoring and display component 3 also includes a bracket 301, which is U-shaped. A photoelectric transmitter 302 and a photoelectric receiver 303 are fixedly mounted at both ends of the U-shaped opening of the bracket 301. The bracket 301 is fixedly mounted at the end of the horizontal displacement amplifying rod structure 7. When the horizontal displacement misalignment between the lower support 1 and the upper support 2 is zero, the central light-shielding area plate 306 is located between the photoelectric transmitter 302 and the photoelectric receiver 303. A PLC controller 4 is mounted on the lower support 1, and the output terminals of the photoelectric transmitter 302 and the photoelectric receiver 303 are electrically connected to the input terminal of the PLC controller 4. Specifically, the photoelectric transmitter 302 and the photoelectric receiver 303 can also be replaced with a light transmitter and a light sensor, mainly used to transmit the detected electrical signal to the PLC controller 4 when the central light-shielding area plate 306 deviates from between the photoelectric transmitter 302 and the photoelectric receiver 303.

[0043] The central light-blocking area plate 306 is circular in shape. The surrounding light-transmitting area plate 305 has several sets of offset indicator scale marks 308 evenly distributed at equal angles around the central light-blocking area plate 306. Each set includes several offset indicator scale marks 308 evenly distributed radially along the circular surrounding light-transmitting area plate 305. In practical applications, the offset indicator scale marks 308 are used by workers for visual observation.

[0044] Two supports 301 are each equipped with a displacement sensor 304 for detecting the displacement distance between the outer surfaces of the lower support 1 and the upper support 2. Each support 301 is also equipped with a warning light 310. The output of the displacement sensor 304 is electrically connected to the input of the PLC controller 4, and the output of the PLC controller 4 is electrically connected to the input of the warning light 310. In practical applications, when the two displacement sensors 304 detect a change in the outer surfaces of the lower support 1 and the upper support 2 that reaches a certain value, they transmit the detected electrical signal to the PLC controller 4. The PLC controller 4 then controls the warning light 310 to illuminate as a warning. Additionally, a wireless signal transmitter can be installed on the support 301 to transmit the signal to a remote control center, enabling remote monitoring by personnel.

[0045] The damping assembly 6 includes a third mounting collar 601, which is fixedly installed on the outer side of the lower end of the lower support 1. Several first L-shaped support rods 602 are evenly distributed at equal angles around the lower support 1 and fixedly installed on the outer side of the third mounting collar 601. A bottom support rod 606 is fixedly installed at the top of each first L-shaped support rod 602. A viscous damper 604 is fixedly installed on the bottom support rod 606. A triangular positioning clamp 605 is fixedly connected to the push rod head of the viscous damper 604. The damping assembly 6 also includes second L-shaped support rods 603 that correspond to the first L-shaped support rods 602. Each second L-shaped support rod 603 is fixedly connected to the second mounting collar 501. The bottom support rod 606 is fixedly connected to the second L-shaped support rod 603 by bolts.

[0046] Working principle:

[0047] In use, this application is applicable not only to columnar building structures composed of a lower support 1 and an upper support 2, but also to upper and lower wall building structures. It is used to amplify and detect the horizontal displacement between upper and lower building structures at an isolation joint. In practical applications, two universal support structures 5 are fixedly installed on the lower support 1 and the upper support 2, respectively. The installation positions of the two universal support structures 5 on the lower support 1 and the upper support 2 are vertically corresponding. The first support 503 of the two universal support structures 5 is fixedly installed first. Then, the universal rotating ball 702 of the horizontal displacement amplification rod structure 7 is embedded into half of the universal ball groove 505 of the first support 503. Finally, the second support 504 is fixedly connected to the first support 503 via connecting bolts 507. (See attached instruction manual). Figure 8 As shown, when the horizontal displacement of the lower support 1 and the upper support 2 is zero, both displacement amplification rods 701 are in a vertical state. When the vertical displacement of the lower support 1 and the upper support 2 is a certain value x, the vertical position of the two universal rotating balls 702 remains unchanged, the distance between the centers of the two universal rotating balls 702 increases, and the support spring 706 undergoes elastic deformation. At this time, the displacement change of the end of the displacement amplification rod 701 away from the universal rotating ball 702 is y, thus realizing the amplified display of the displacement.

[0048] Specifically, the elastic deformation structure is used in practical applications to ensure the amplification of horizontal displacement in the following application scenarios: 1. Horizontal displacement occurs between the lower support 1 and the upper support 2; 2. Vertical displacement occurs between the lower support 1 and the upper support 2; 3. Both horizontal and vertical displacements occur between the lower support 1 and the upper support 2 simultaneously. In all three scenarios, when the distance between the two universal rotating spheres 702 changes, the elastic deformation structure undergoes elastic deformation to adapt to this change and provide support. Furthermore, when the horizontal displacement between the lower support 1 and the upper support 2 changes, it drives the two displacement amplification rods 701 to rotate a certain angle within the universal ball groove 505 through the universal rotating spheres 702, thereby achieving the change in horizontal displacement.

[0049] When the horizontal displacement is monitored and displayed by the displacement monitoring and display component 3, if a horizontal displacement occurs between the lower support 1 and the upper support 2 and the horizontal displacement is lower than a certain value, the photoelectric transmitter 302 rotates around the universal rotating ball 702 at a certain angle. However, the central light-shielding area plate 306 remains located between the photoelectric transmitter 302 and the photoelectric receiver 303, thus blocking the area between the photoelectric transmitter 302 and the photoelectric receiver 303. When a horizontal displacement occurs between the lower support 1 and the upper support 2 and the horizontal displacement is higher than a certain value, the photoelectric transmitter 302 and the photoelectric receiver 303 rotate around the universal rotating ball 702 at a certain angle. The central light-shielding area plate 306 deviates from the position between the photoelectric transmitter 302 and the photoelectric receiver 303. The photoelectric receiver 303 receives the signal emitted by the photoelectric transmitter 302 and transmits the electrical signal to the PLC controller 4. The PLC controller 4 controls the warning light 310 to illuminate as a warning.
