Traveling mechanism of robot on high voltage transmission line

The invention discloses a traveling mechanism of a robot on a high voltage transmission line, which is characterized in that 3 traveling arms including a fore arm, a middle arm and a rear arm are arranged on a robot main body. When the robot travels on the transmission line, the fore arm and the rear arm are on the same side of the transmission line, and the middle arm is on the other side of the transmission line. Each traveling arm comprises a traveling wheel, a lifting arm, a braking mechanism and a swing arm, wherein one end of the swing arm is connected with the robot main body through a swing joint, and the other end is connected with the lower end of the lifting arm; the traveling wheel is installed at the side part on the upper end of the lifting arm; and the braking mechanism is installed on the lifting arm and below the traveling wheel. The traveling mechanism can drive the robot to conveniently cross various obstacles on the transmission line, and the stability is good.
