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

WIPO Patent Application WO/2021/103544

A1

A device for measuring displacement of a spherical bearing in an X-X direction, comprising a spherical bearing. The spherical bearing comprises a top bearing plate (7) and a bottom bearing plate (1); both sides of the bottom bearing plate (1) are provided with X-direction laser ranging sensors (9) by means of mounting supports (8); the X-direction laser ranging sensors (9) are used for measuring the displacement of the top bearing plate (7) with respect to the bottom bearing plate (1). The displacement in an x-x direction between the top bearing plate (7) and the bottom bearing plate (1) in the spherical bearing is measured by means of the X-direction laser ranging sensors (9), so that the displacement of a bridge can be indirectly measured, facilitating giving early warning when large displacement occurs to the bridge due to vehicle overload or extreme weather or other factors, so as to avoid serious personal safety and property damage accidents.
