DEVICE FOR MEASURING DISPLACEMENT IN Y-Y DIRECTION OF SPHERICAL BEARING

WIPO Patent Application WO/2021/103545

A1

A device for measuring the displacement in y-y direction of a spherical bearing, comprising a spherical bearing; the spherical bearing comprises an upper bearing plate (7) and a lower bearing plate (1), Y-direction laser ranging sensors (11) are provided at the other two sides of the lower bearing plate (1), reflective plates (10) extending downwards are provided at corresponding side surfaces of the upper bearing plate (7), and the Y-direction laser ranging sensors (11) are used to measure the displacement of the upper bearing plate (7) relative to the lower bearing plate (1). The displacement in y-y direction between the upper bearing plate (7) and the lower bearing plate (1) of the spherical bearing is measured by the Y-direction laser ranging sensors (11), so that the displacement of a bridge is indirectly measured, facilitating making early warning when the bridge is significantly displaced due to overloading of a vehicle, or extreme weather or other factors, and avoiding major accidents of personal injury and property damage.
