Fixed point torsion damping support with self-resetting function

Abstract

The invention relates to a fixed point torsion damping support with a self-resetting function and belongs to the field of dampers. The fixed point torsion damping support comprises an upper top plateof the support, a resetting type damping piston cylinder and a bottom bin of the support, wherein the resetting type damping piston cylinder is fixed in the bottom bin of the support through a fixingblock and a bolt, and the upper top plate of the support is connected with a piston rod bulb of the resetting type damping piston cylinder and a central post on the bottom bin of the support and is arranged at the uppermost end of the support. The support provided by the invention can control the torsion amplitude of a bridge and change vibration characteristics to avoid brittle failure of connecting parts so as to improve the safety of the bridge; furthermore, under large torsion vibration, by virtue of damping characteristics, the support can effectively reduce high-frequency vibration caused by wind and earthquake, control the relative vibration amplitude of the bridge and a bridge deck as well as consume external energy input; after the vibration is finished, the support can be automatically reset; and the support has the advantages of wide applicability, convenient installation, automatic resetting, replaceable parts and the like.

Description

technical field [0001] The invention relates to the field of dampers, in particular to a fixed-point torsional damping support with self-resetting function. Background technique [0002] The bridge deck of the bridge is usually supported on the bridge piers. During the use of the bridge, the bridge is subjected to transverse wind, earthquake, dynamic load on the bridge deck, etc., and the relative torsional movement of the bridge deck and the bridge piers is easy to occur. It will affect the normal use of the bridge, and even cause fatigue damage to the bridge structure. In severe cases, it will also lead to the overall damage of the bridge structure, which will have a great impact on the safety of the bridge structure, the operation safety of vehicles on the bridge and the comfort of passengers. , so the torsion bearing is of great significance for solving such problems. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the pres...
