Shock absorption and isolation support for bridge

Abstract

The invention relates to the technical field of building construction, in particular to a shock absorption and isolation support for a bridge. The shock absorption and isolation support comprises a main body mechanism, a shock absorption mechanism, a lubricating mechanism, connecting blocks, a push rod, a sliding block, a sliding plate, a pressure spring, an oil injection pipe and a hose. A plurality of connecting blocks are mounted on the side wall of the shock absorption at equal intervals; one end of the push rod is installed on the side of the connecting blocks, the other end of the push rod is fixed on the side wall of the sliding block; the sliding block is fixed with one end of the pressure spring and slides in the sliding plate; the sliding plate is mounted in the main body mechanism; the other end of the pressure spring is connected with the main body mechanism; one end of the hose is communicated with the inside of the sliding plate, and the other end of the hose is communicated with the shock absorption mechanism; when the shock absorption mechanism slides, the connecting blocks drive the push rod to extrude the sliding block, then lubricating oil flowing into the sliding plate from the oil injection pipe flows into the hose under extrusion of the sliding block, the lubricating oil is conveyed into the shock absorption mechanism through the hose, and therefore the situation that the sliding damping efficiency is reduced due to the fact that the interior of the support is affected with damp and rusted is prevented while damping is conducted on the support.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a shock-absorbing and isolating bearing for a bridge. Background technique [0002] Bridge isolation: that is, an isolation layer with integral reset function is set between the bridge foundation, bottom or substructure and superstructure with laminated rubber isolation bearings to prolong the natural vibration period of the entire structural system and reduce input The horizontal seismic action of the upper structure meets the expected seismic requirements. [0003] However, traditional bridge shock-absorbing bearings may not be able to achieve better shock-absorbing effects, especially in the case of large vibration amplitudes, and the impact resistance is insufficient; in addition, after long-term use, the inside of the bearing is prone to moisture Rust leads to poor sliding effect, and is also not conducive to improving the shock absorption efficiency of the be...
