AI Technical Summary

Technical Problem

The existing methods for adjusting the height of bridge bearings are cumbersome and ineffective, making it difficult to meet the height requirements between the pier and the bottom of the beam.

Method used

A stepless height-adjustable spherical support was designed. By setting an adjustment ramp and a limiting plate inside the support, the stepless height adjustment of the support is achieved by using the ramp and conical surface structure. A sealing ring is used to prevent foreign objects from entering, ensuring the accuracy and safety of the height adjustment.

Benefits of technology

It enables easy adjustment and efficient height adjustment of the support, ensuring the safety and accuracy of the height adjustment process, while preventing rust and foreign objects from entering, thus extending the service life of the support.

Abstract

This utility model belongs to the field of bridge bearing technology and discloses a stepless height-adjustable spherical bearing. Its main technical features are: it includes an upper bearing plate, a spherical crown plate, and a lower bearing plate; an intermediate inclined plate and a height-adjusting inclined plate are provided between the spherical crown plate and the lower bearing plate; along the front-to-back height adjustment direction, the contact surface between the height-adjusting inclined plate and the intermediate inclined plate is an inclined surface, and the contact surface between the height-adjusting inclined plate and the lower bearing plate is a straight surface; along the left-to-right non-height adjustment direction, the contact surface between the height-adjusting inclined plate and the intermediate inclined plate is a first conical inclined straight surface, and the contact surface between the height-adjusting inclined plate and the lower bearing plate is a second conical inclined straight surface; a limiting plate with anti-loosening bolts is provided on the rear side of the lower bearing plate; baffles with grooves are provided on the left and right sides of the lower bearing plate; and protrusions matching the grooves are provided on the left and right sides of the intermediate inclined plate. The stepless height-adjustable spherical bearing provided by this utility model offers simple adjustment and good adjustment effect during the bearing height adjustment process.
