Description

Technical Field

[0001] This utility model relates to the field of viscous damper technology, and in particular to a multifunctional operating platform for testing viscous dampers. Background Technology

[0002] Viscous dampers are widely used in modern construction engineering due to their excellent vibration reduction effect and long service life. However, because their construction quality is affected by many factors and involves various technical challenges, ensuring the reliability and long-term operation of viscous dampers has become a focus of attention for engineering technicians. Viscous dampers play a crucial role in modern buildings and engineering structures. Their main function is to reduce structural vibration and stress by absorbing and dissipating vibration energy, thereby protecting the safety of buildings and infrastructure. Given their importance in natural disasters such as earthquakes and wind loads, ensuring the stability and reliability of viscous damper performance is particularly important. Currently, there is a lack of equipment for multi-functional testing of viscous dampers, which severely restricts testing and production operations. Utility Model Content

[0003] The purpose of this invention is to provide a multifunctional operating platform for testing viscous dampers. This platform can test the dynamic characteristics, damping characteristics, fatigue performance, sealing performance, and other properties of viscous dampers to simulate potential problems under extreme conditions such as earthquakes and wind loads. This helps engineers optimize the design of viscous dampers and ensure the stability and reliability of their performance.

[0004] To achieve the above objectives, this utility model provides a multifunctional operating platform for testing viscous dampers, including a first main beam and a second main beam, with a first crossbeam and a second crossbeam fixedly connected to both sides of the first main beam and the second main beam, respectively. The graded crossbeams are fixedly installed between the first frame main beam and the second frame main beam; Rolling pulleys are respectively installed on the first main beam and the second main beam, and a sliding crossbeam is provided between the rolling pulleys. The rolling pulleys are rotatably mounted on the sliding crossbeam. A damper is detachably installed between the sliding crossbeam and the graded crossbeam. The damper is fixed by a lug and a pin and is driven to move by a hydraulic actuator on one side of the first frame crossbeam. The hydraulic actuator is connected to the sliding crossbeam through a transmission rod.

[0005] The pins are located on both sides and connected to the ear plate via connecting plates to fix the damper.

[0006] The graded crossbeam is provided with a set of ear plates, and a pin hole is provided in the middle of the ear plate. The pin shaft is inserted into the pin hole and automatically adapts to the height difference between the two ends of the ear plate.

[0009] This invention discloses a multifunctional operating platform for testing viscous dampers. The platform has a pin at each end to ensure the testing of the horizontal force on the damper. Rolling pulleys mounted on a sliding beam serve as movable supports, stably enabling dynamic and static loading tests on the damper. This meets the requirements for simulating horizontal seismic forces. Because the platform is easy to assemble and disassemble, it can be used for testing under various environmental conditions, reducing equipment costs.

[0017] In this embodiment, the first main beam 1 and the second main beam 2 are used for support and coordination.

[0018] The first frame main beam 1 and the second frame main beam 2 are respectively fixedly connected to the two sides of the first frame crossbeam 3 and the second frame crossbeam 4; the first frame crossbeam 3 and the second frame crossbeam 4 are respectively connected to the first frame main beam 1 and the second frame main beam 2 by countersunk bolts to achieve assembly.

[0019] The graded crossbeam 5 is fixedly installed between the first main beam 1 and the second main beam 2 of the frame; the two sides of the graded crossbeam 5 are respectively connected to the first main beam 1 and the second main beam 2 of the frame by countersunk bolts to achieve assembly.

[0020] Rolling pulleys 8 are respectively mounted on the first main beam 1 and the second main beam 2 of the platform, and a sliding crossbeam 6 is provided between the rolling pulleys 8. The rolling pulleys 8 are rotatably mounted on the sliding crossbeam 6. The rolling pulleys 8 are directly mounted on both sides of the sliding crossbeam 6 through rotating bearings, and can roll on the first main beam 1 and the second main beam 2 respectively, realizing the movement of the sliding crossbeam 6. A 0.5 mm wear-resistant coating, which is a carbide coating, is provided at the contact points between the rolling pulleys 8 and the surfaces of the first main beam 1 and the second main beam 2.

[0021] A damper 7 is detachably installed between the sliding crossbeam 6 and the graded crossbeam 5. The damper 7 is fixed by a lug 11 and a pin 10, and is driven to move by a hydraulic actuator 9 on one side of the first frame crossbeam 3.
