Description

Technical Field

[0001] The present invention relates to the field of bridge engineering detection, and in particular to a highway bridge bearing deformation detection device. Background Art

[0002] Bridge bearings are important structural components that connect the superstructure and substructure of a bridge. They can reliably transmit the reaction force and deformation (displacement and rotation) of the superstructure to the substructure, so that the actual stress conditions of the structure are consistent with the calculated theoretical diagram.

[0003] In bridge engineering inspection, it is necessary to carry out deformation inspection on bridge bearings, generally to inspect their lateral deformation. Since bridge bearings are installed between piers and beams, inspection is more troublesome, and bearing deformation generally occurs under load, resulting in long inspection time and inconvenience. Further improvements can be made. At the same time, when bridge bearings are lateral deformed, they will also produce vertical deformation due to dynamic load pressure. Traditional inspection equipment is not convenient for detecting lateral and vertical deformations at the same time, resulting in incomplete inspection data. Further improvements can be made. In addition, traditional inspection equipment corresponds to the bearing model, and it is not convenient to adjust and apply to bridge bearings of different diameters and heights, resulting in reduced applicability. Further improvements can be made.
