PROBLEM TO BE SOLVED: To provide a pipeline internal inspection device capable of inspecting a pipeline having a structure arranged in the inside center thereof, while being self-propelled the inside thereof.SOLUTION: A pipeline internal inspection device for inspecting a pipeline 3 having a structure 2 arranged in the inside center thereof includes a travel device 7 self-traveling the inside of a pipeline 3. The travel device 7 has an imaging device 10 for imaging the inside of a pipeline 3, a wheel 8 rotating by coming into contact with the inner peripheral surface 3a of the pipeline 3, and a driving device 9 for rotary driving the wheel 8. The pipeline internal inspection device is configured to travel in the circumferential direction of the pipeline 3, when the wheel 8 is rotary driven, and can travel in the longitudinal direction of the pipeline 3, while maintaining the posture by a gripping force occurring between the inner peripheral surface 3a of the pipeline 3, at any position in the circumferential direction. |
