PIPING DECONTAMINATION DEVICE

PURPOSE:To remove crad of pipings and the like in actual machine as in-place state by connecting and inserting a work main body and a work power transmitter body etc. from the narrow open space such as valves in decontamination object piping system. CONSTITUTION:A work body 10, a moving transmitter 11, a work power transmitter 12 are inserted in pipings from narrow open spaces 16 such as valves in decontamination object piping system. That is, the main body 10 and the transmitter 12 are inserted after connecting and the transmitter 11 is connected beside the insertion place. Thus, with a sproket 18 of a moving power generator 13 placed on the flange surface 17 of a valve, the moving power is transmitted to the pins 19 of each constituting element of the transmitter 11. By this, the main body 10, decontaminating inside surface of the pipings, proceeds goes back) in the transmitter 11 so as to decontaminate continuously the whole work region. And the transmitter 11 is constituted by chaining the elements of rectangle rink 43, and each rink 43 is connected with the pin 19 and has a guide roller 36.
