PURPOSE:To provide an in-pipe moving device which can move in a pipe with simple structure and can be used for in-pipe cleaning devices and various inspecting devices without a fear of damaging the inner face of the pipe. CONSTITUTION:This in-pipe moving device is constituted of chambers 1 and 2 and a bellows 3 connected to these chambers 1 and 2. The chambers 1 and 2 are provided with a space enclosed by rubber films 5 and 9, respectively, and when compressed air is supplied into the chambers 1 and 2, the rubber films 5 and 9 are expanded in the diameter direction of a pipe 15 to press the inner face of the pipe 15. The bellows 3 is normally in the contracted state, and by supplying the compressed air into the bellows 3, it is extended in the longitudinal direction of the pipe 15. Supply of air to the chambers 1 and 2 and the bellows 3 is executed by a controller based on a predetermined sequence. |
