Expansion joint width gauge for bridge detection

Abstract

The utility model discloses an expansion joint width gauge for bridge detection, which belongs to the technical field of bridge detection and comprises a distance sensor, a distance measuring piece, a main body, a first rotating wheel, a second rotating wheel, a driving piece, a first connecting rod and a second connecting rod. The first connecting rod and the second connecting rod are symmetrically arranged on the two sides of the cavity, the middles of the first connecting rod and the second connecting rod are rotationally connected with the through groove, the first rotating wheel is rotationally connected to the end, away from the cavity, of the first connecting rod, the driving part is fixedly connected to the end, away from the cavity, of the second connecting rod, and the second rotating wheel is fixedly connected to the output end of the driving part. According to the bridge expansion joint width gauge, the problems that an existing width gauge cannot carry out whole-line detection on a bridge expansion joint, installation is extremely inconvenient, and then the bridge detection effect is affected are solved.
