Description

Technical Field

[0001] This utility model belongs to the field of popular science education technology, and specifically relates to a vibration isolation rubber bearing vibration isolation effect demonstration device. Background Technology

[0002] Earthquakes are one of the most significant natural disasters affecting humankind. After an earthquake occurs, it causes severe casualties and property damage, resulting in extensive damage to building structures, electromechanical systems, bridges, and other structures, causing immense loss of life and property. Seismic isolation technology avoids the damage of earthquakes to buildings and pipelines, enabling important locations such as schools, kindergartens, and hospitals to meet normal operating requirements during earthquakes, thus reducing casualties and property losses.

[0003] Seismic isolation bearings are support devices installed on structures to achieve seismic isolation requirements. They add an isolation layer between the superstructure and the foundation. The main classifications include rubber seismic isolation bearings, elastic sliding plate bearings, and friction pendulum seismic isolation safety bearings. Rubber seismic isolation bearings are products made by alternating layers of steel plates and rubber, vulcanized under high temperature and pressure. The steel plates act as stiffening materials in the rubber bearing, overcoming the relatively low vertical stiffness of the rubber body, allowing it to reduce horizontal seismic forces while withstanding larger vertical loads. Because rubber, as an elastic body, has insufficient energy dissipation capacity, a lead core is added to the bearing. Lead-core rubber seismic isolation bearings provide both damping and yield strength, enabling them to resist wind loads.

[0004] Vibration isolation of building foundations is an effective measure for reducing seismic activity. Current teaching and popular science methods for explaining seismic isolation measures typically rely on lectures, books, posters, and other media. These methods often involve technical jargon, lack practical experience, and haven't provided real-world examples, making understanding difficult and resulting in a deficiency in knowledge about seismic isolation technology. Therefore, there is a lack of equipment specifically designed to demonstrate the effectiveness of seismic isolation bearings. Consequently, providing a device for demonstrating the seismic isolation effect of rubber bearings is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0025] In this embodiment, the vibration isolation device 4 includes a rubber vibration isolation column 4.2 and a flange plate 4.1. Both ends of the rubber vibration isolation column 4.2 are detachably connected to the flange plate 4.1. The flange plate 4.1 is provided with multiple mounting holes. One end of the flange plate 4.1 of the rubber vibration isolation column 4.2 is connected to the building model chassis 3 through the mounting holes and fixing screws 4.3. The other end of the flange plate 4.1 of the rubber vibration isolation column 4.2 is connected to the building model 2 through the mounting holes and fixing screws 4.3. The rubber vibration isolation column 4.2 is used for vibration buffering.

[0026] In this embodiment, the drive box is also equipped with a speed controller 7, which is electrically connected to the drive assembly 6. The speed controller 7 is also equipped with a speed knob 7.1 and a switch knob 7.2. The speed controller 7 is specifically a PLC controller, which can control the drive motor 6.4 to adjust the intensity of the vibration simulation.

[0027] In this embodiment, the driving assembly 6 includes a cam follower 6.1, a motor mounting plate 6.2, support columns 6.3, a drive motor 6.4, and a cam follower track 6.5. The bottom end of the motor mounting plate 6.2 is detachably connected to the drive motor 6.4 and multiple support columns 6.3. The bottom end of the support columns 6.3 is fixedly connected to the inner wall of the housing. The output end of the drive motor 6.4 passes through the motor mounting plate 6.2 and is connected to the cam follower 6.1. The cam follower 6.1 is slidably connected to the cam follower track 6.5 fixed at the bottom end of the building model chassis 3. The drive motor 6.4 is electrically connected to the speed controller 7. The cam follower 6.1 drives the building model chassis 3 to move back and forth along the cam follower track 6.5.

[0028] In this embodiment, two linear bearing sliding assemblies 5 are also connected inside the drive box at the bottom of the building model chassis 3. The linear bearing sliding assembly 5 includes an optical axis support 5.1, an optical axis 5.2, and a linear bearing 5.3. The optical axis 5.2 is detachably connected between the two optical axis supports 5.1. Multiple linear bearings 5.3 are provided on the optical axis 5.2.

When the drive motor 6.4 is started, the swing arm 6.6 rotates, driving the connecting shaft to rotate, and causing the cam follower track 6.5 and the building model chassis 3 to vibrate. At the same time, the connecting shaft is restricted to move at the strip-shaped through hole on the cam follower track 6.5 to simulate an earthquake.

[0030] Working principle: The speed controller 7 controls the start of the drive motor 6.4 and controls the speed of the drive motor 6.4. The output of the drive motor 6.4 drives the swing arm 6.6 to rotate, so that the cam follower 6.1 moves along the cam follower track 6.5 and realizes the vibration simulation of the building model chassis 3. The building model chassis 3 is restricted by the linear bearing 5.3 to move along the optical axis 5.2. When the building model chassis 3 vibrates or moves, the vibration effect is transmitted to the two building models 2 through the vibration isolation device 4 and the connecting plate. The vibration isolation effect is judged by observing the water cup 1 placed on the top of the building model 2.
