PROBLEM TO BE SOLVED: To introduce a device main body into an intended branch pipe by providing a device main body which includes traveling, watching and work means and is capable of freely moving in a branch pipe and a transport body which includes a traveling means, stores the device main body in the interior thereof, and is capable of freely moving in a main pipe in a piping comprising a main pipe and a branch pipe. SOLUTION: A device main body 2 is stored on a transport body 6, and in such a condition, the transport body 6 inserted together with the device main body into a main pipe 10. A creeping mechanism is driven by controlling an air cylinder of traveling means 7 in front of and in rear of the transport body 6 from the outside of the piping, and the transport body 6 is moved in the main pipe 10. Subsequently, an intended branch pipe 12 is confirmed by a camera 4 provided on the device main body 2, and the creeping mechanism is stopped to fix the transport body 6 in the main pipe at the branch pipe opening part. After that, a cord 81 is delivered by a winch loaded on the transport body 6 to separate the device main body 2, and when a crawler 3 is driven, the device main body freely travels in the branch pipe 12 to conduct work. Thus, the device can conduct work while freely moving in an intended branch pipe. |
