Bridge cable inspection robot capable of crossing obstacles

Abstract

A bridge cable inspection robot capable of crossing obstacles includes: a structure, a movement unit, a control unit, a monitoring unit, a battery unit, and a measurement unit. The structure is formed as a separable, circumferentially enclosed frame surrounding the cable. The movement unit includes a first driving wheel and a first driven wheel arranged at equal angles along the circumference of a first end of the structure, and a second driving wheel and a second driven wheel arranged at equal angles along the circumference of a second end of the structure. The driven wheels are provided with elastic force by an elastic mechanism to properly clamp the cable in conjunction with the driving wheels. The driving wheels are driven by a motor to move the structure along the cable to a predetermined position, and during movement, it can cross obstacles on the cable without slipping. The measurement unit measures the vibration frequency of the cable, and the monitoring unit photographs the surface of the cable, thereby reducing the high risk of manual cable inspection and minimizing disruption to surrounding traffic.
