AI Technical Summary

Technical Problem

Existing high-altitude bridge seismic isolation bearings are unable to effectively disperse the buffer pressure on the bearing columns, resulting in easy damage to the bearing columns, short service life, and inconvenient replacement.

Method used

The system employs two sets of buffer mechanisms, including a combination design of dampers, rectangular frames, grooves, sliders, leaf springs, and return springs. By sliding the slider within the groove and cooperating with the springs, the pressure on the support column is dispersed, thereby improving the buffering effect.

Benefits of technology

It effectively improves the service life of the support column and the vibration reduction efficiency of the high-altitude bridge, and reduces the wear risk of the support column.

Abstract

The utility model relates to the technical field of shock insulation support, propose a kind of high-altitude bridge shock insulation support structure, comprising: upper fixed plate, lower fixed plate and support column body, the top of support column body is fixedly connected with the bottom of upper fixed plate, the bottom of support column body is fixedly connected with the top of lower fixed plate, two groups of buffer mechanism, relatively set between upper fixed plate, lower fixed plate, two groups of buffer mechanism include two dampers of two opposite fixed installation in the top of lower fixed plate, two dampers are located at the two sides of support column body, and the output end of two dampers is fixedly connected with rectangular frame. The pressure of high-altitude bridge is downwardly pressed blade spring, so that slider slides inside sliding slot, resets spring to contract, under the cooperation of reset spring and blade spring, the pressure for buffering support column body is dispersed, effectively improve the service life of support column body, and high-altitude bridge damping efficiency.
