Walking type power line obstacle-crossing inspection robot along line

The invention discloses a walking type obstacle-crossing inspection robot for an electric power circuit along a line. The robot comprises a control box, mechanical arms, three walking mechanisms and alead screw mechanism. A plate surface is arranged on the upper surface of the control box, the lead screw mechanism is fixedly installed on the plate surface, the walking mechanism is installed on the lead screw mechanism, the walking mechanisms are installed at the two ends of the plate surface of the control box in the power transmission line direction through mechanical arms in a connected mode, and the three walking mechanisms are located on the same horizontal plane and form a straight line. According to the robot, automatic walking on the power transmission line is achieved through thethree driving wheels, obstacle crossing of the robot is achieved through three-arm obstacle crossing and sequential offline of the three walking mechanisms through the mechanical arm, the robot adaptsto different power transmi
