RADIOGRAPHIC JIG

PURPOSE:To eliminate the possibility of blurring due to vibration of piping and to set a radiographic film at a fixed distance from the piping by disposing three outer shafts each of which is freely slidable against an inner shaft, and adding a piping fixing block to the center outer shaft, a radiographic film fixing block to the next outer shaft, and a radiation source fixing block to the other outer shaft. CONSTITUTION:A piping fixing block 3 is mounted to a center outer shaft 12 with sling belts 5 provided on piping 4 for inspection, the center outer shaft 12 being freely slidable against an inner shaft 6; a left end outer shaft 10 is freely slidably fitted over the left side of the shaft 6 and a radiographic film fixing block 1 is set on the shaft 10. A right end outer shaft 9 is freely slidably fitted over the right side of the shaft 6 and the shaft 9 is cross-shaped and a radiation source fixing inner shaft 7 is provided in such a manner that a radiation source fixing portion 2 is vertically movable. Thereby the position of the radiation source of the fixing portion 2 can be set in such a manner as just crossing the center line of the piping 4 and reaching the radiographic film. Because the film and the radiation source are vibrated integrally with the subject for inspection, the possibility of blurring due to vibration is eliminated.
