Problems solved by technology

[0005] The purpose of the present invention is to overcome the limitations of the existing cylindrical damper due to the limitation of the device structure, the damping force tonnage of a single device is limited, it cannot meet the shock absorption requirements of large bridges, and at the same time, the working direction is single, oil leakage is easy, and the damping force is limited. A super-large tonnage multi-directional energy dissipation damper that can resist impact force and consume most of the vibration energy generated by earthquake action to protect the main structure

Abstract

The invention discloses an impact-resistant ultra-high-tonnage multidirectional energy dissipation damper, which consists of a bottom plate, impedance plates, side plates, a top plate, a transmission support frame and an upper part connecting plate. The impedance plates are built in a steel box body formed by welding the bottom plate, the side plates and the top plate; the steel box body is fully filled with viscous fluid; the impedance plates comprise fixed impedance plates and a movable impedance plate; the fixed impedance plates are welded on the side plates; the movable impedance plate is connected with an upper part connecting device through the transmission support frame; a shear key is arranged on the movable impedance plate. The movable impedance plate is driven by the upper part connecting device and the transmission support frame; the movable impedance plate moves in the viscous fluid; the viscous fluid is sheared, and meanwhile, the damping force is generated. The impact-resistant ultra-high-tonnage multidirectional energy dissipation damper has the advantages that the stable conversion of a structure aseismatic system can be ensured; the ultra-high-tonnage multidirectional impact-resisting, energy dissipation and seismic mitigation effects can be achieved; stability, reliability, low cost and excellent seismic mitigation performance are realized; the damping force requirements in any direction in the horizontal plane can be met. The impact-resistant ultra-high-tonnage multidirectional energy dissipation damper can be used in the fields such as bridges and buildings with great requirements on energy dissipation and seismic mitigation.

Description

technical field [0001] The invention relates to an energy-dissipating shock-absorbing device, in particular to a multi-directional energy-dissipating damper capable of anti-shock and extra-large tonnage. Background technique [0002] Earthquake is one of the worst natural disasters suffered by human beings. Earthquake disasters are sudden and destructive, often causing serious disasters in a moment. In recent decades, dozens of strong earthquakes have occurred all over the world, causing huge casualties and economic losses, and bringing huge trauma to human society. my country is an earthquake-prone country, and quite a large area is located in the Eurasian seismic belt and the circum-Pacific seismic belt. Major earthquakes in mainland China in recent decades, such as the Tangshan earthquake in 1976, the Fengchuan earthquake in 2008, and the Yushu earthquake in 2010, have caused a large number of casualties and huge economic losses. Strong earthquakes will not only directl...
