Walking device of rain sewage pipe network detection robot

The invention discloses a walking device of a rain and sewage pipe network detection robot, relates to the technical field of walking of robots, and is used for solving the problem that the walking device of the rain and sewage pipe network detection robot in the prior art is inconvenient to enable the detection robot to change walking tracks. Transition rails are installed among the multiple walking rails, the distance between the transition rails and the ground is larger than the distance between the walking rails and the ground, transition motors are installed on the bottom faces of the transition rails, opposite penetrating holes are formed in the walking rails, and telescopic rotating mechanisms are installed below the opposite penetrating holes. And an adsorption part is mounted at the upper end of the telescopic rotating mechanism. According to the invention, the detection robot can reach the other walking track from one walking track through the transition track, so that the walking tracks of the robo
