Cable detection robot and working method thereof

A cable detection robot, comprising:

• a first main body, a second main body, and a rotatable mechanism connecting the first main body and the second main body, wherein the first main body and the second main body each comprise a support, and a driving apparatus and a holding apparatus arranged on the support;
• the driving apparatus comprises a first wheel and a driving motor, to drive the first wheel to move along a cable through the driving motor;
• the holding apparatus is symmetrically arranged on two sides of the support, each side comprises a first servo motor, a first supporting rod, and a second supporting rod that are connected sequentially, an adjustable bracket is respectively arranged on the first supporting rod and the second supporting rod, and the adjustable bracket is connected to a supporting wheel group;
• a rotation joint configured to adjust the angle is arranged at a junction of the first supporting rod and the second supporting rod;
• the rotation joint connects the first supporting rod and the second supporting rod in a bolted connection manner, to adjust the rotation angle between the first supporting rod and the second supporting rod;
• an angle between the first supporting rod and the second supporting rod matches a diameter of the cable, the supporting wheel group is perpendicular to a surface of the cable by adjusting a height of the adjustable bracket and adjusting relative positions of the supporting wheel group and the surface of the cable, the holding apparatus holds or is separated from the cable through rotation of the first servo motor, and relative positions of the first main body and the second main body are adjusted through the rotatable mechanism to implement obstacle surmounting;
• the adjustable bracket comprises a first sleeve, a second sleeve, an elastic member, and a telescopic rod, the adjustable bracket is fixed to the first supporting rod and the second supporting rod through the first sleeve, the first sleeve is connected to the second sleeve, the telescopic rod is arranged in the second sleeve, and the telescopic rod is connected to the supporting wheel group through the elastic member;
• and
• the supporting wheel group comprises a chassis, and joints and second wheels arranged on the chassis;
• and the chassis is connected to the adjustable bracket, and the second wheels are connected at two ends of the chassis through the joints.
