A torsional damper device

Abstract

The invention relates to technical fields such as buildings, bridges, and lifeline engineering, and in particular to a torsional damper device for seismic isolation of construction engineering, bridge engineering, equipment engineering, and major lifeline engineering, including an upper barrel and a lower barrel socketed with the upper barrel The barrel body, rotating blades, upper guide rail system and lower guide rail system, when an earthquake causes horizontal torsion, the shock isolation structure drives the upper guide rail system, the upper barrel body and the rotating blades installed in the upper barrel body to rotate, because the lower barrel body is equipped with The damping liquid will drive the damping liquid to rotate when the rotating blade rotates, and the damping liquid will pass through the retention hole, which will generate energy consumption damping and play the function of shock absorption. The upper guide rail system and the lower guide rail system in the device can ensure that the damper The device can move without obstacles and in any horizontal direction, so as not to affect the horizontal shock absorption function of the shock-isolation rubber bearing.

Description

technical field [0001] The invention relates to technical fields such as buildings, bridges, and lifeline engineering, and in particular to a torsional damper device for seismic isolation of construction engineering, bridge engineering, equipment engineering, and major lifeline engineering. Background technique [0002] A large destructive earthquake, if it occurs in a densely populated and economically developed area or city, will kill thousands of people in tens of seconds or even a few seconds, and hundreds of thousands of buildings will be destroyed. (Structure) buildings are reduced to ruins, and hundreds of bridges collapse. The former will cause a lot of loss of people and property, and the latter will not only cause huge economic losses due to traffic interruption, but also cause great difficulties for earthquake rescue. , missed the critical opportunity to rescue personnel; and as the storage tank of the lifeline project, the earthquake not only leads to the loss of...

Problems solved by technology

However, due to the uncertainty of earthquakes, for example, in addition to horizontal earthquakes, there are also vertical earthquakes, horizontal torsional components, etc. At the same time, the setting of rubber bearings cannot ensure that the center of mass and the center of rigidity can coincide well during earthquakes. It will cause different degrees of torsion in the upper structure of the isolation bearing, but there is no mature anti-torsion bearing yet. In order to reduce torsional shock damage, it is necessary to install a certain number of torsional dampers with torsional energy dissipation function.
