The invention discloses a
detector for detecting the outline cross section shape of a bridge cable. The
detector comprises a climbing
robot, a transition sleeve, a rotary supporting seat, a rotary sleeve and a
ranging sensor. The detecting object is a bridge cable cylinder, the climbing
robot is located on the to-be-detected bridge cable cylinder, the transition sleeve is coaxially installed on the climbing
robot by adopting two semicircles with same diameters, and the rotary supporting seat is fixedly connected with the transition sleeve. The rotary sleeve wraps a plurality of circumferentially distributed rolling columns through two semicircular structures, and the rotary sleeve can rotate positively and negatively around the bridge cable cylinder. The
ranging sensor is located on the rotary sleeve and used for measuring the cross section shape of the bridge cable cylinder. The
detector provided by the invention can conveniently penetrate through the to-be-detected cable and be arranged around the cable, and can rotate flexibly according to requirements. The detector fills in the gap that rotation of traditional cable movable detection cannot be achieved, cable
damage detection meets the requirement for no blind angles, meanwhile cable
damage detection is simple and reliable, and the detector has the great application value.
