[0022] The working principle of the turbine blade blade crown ray detection platform is as follows:

[0023] When in use, since the tenon clamp 13 clamping surface shape is the same as the shape of the blade tenon, the blade can be stably clamped on the tenon clamp without falling off easily, and since the tenon clamp 13 is made of nylon material, it can effectively prevent the blade tenon from being damaged when inserted into the tenon clamp 13. Then it is fixed on the locking clamp 11 by bolts, the locking clamp 11 penetrates into the clamp cross bar 10, and the angle can be adjusted by 360 degrees. According to the ray penetration process, the angle is adjusted to the appropriate angle and fixed by the locking nail 12. The lead plate 8 with a certain thickness is used as a platform for placing the film and also for protecting against backscattered rays during the ray detection process. The height of the lead plate 8 can be adjusted by the threaded lifting rod 7, which is suitable for blades of different lengths, and the height of the lead plate 8 is adjusted during detection to make the blade crown detection part as close to the film as possible, reduce the geometric uncertainty in the process of ray imaging, and improve the image quality of radiography. The eight-pronged vertical support 6 is installed at the center of the entire detection platform, which is also the center of the ray source during ray detection. The eight vertical supports around it are used to support the clamp cross bar 10. The top of the eight-pronged vertical support 6 is U-shaped, which facilitates the replacement of different clamp cross bars 10 or different tenon clamps 13. The technician can move the detection platform by pushing the handle, and the platform can be locked to prevent movement during ray penetration. A horizontal bar is connected in the middle of the handle, and a storage groove is installed in the middle of the horizontal bar, which can be used to place auxiliary equipment during ray detection. Through this platform, the turbine blade detection blade crown can be quickly clamped and placed, and the penetration arrangement can be carried out outside the ray machine room, without staying in the machine room for a long time. Once detection is completed, the operation time is short, which greatly improves the detection efficiency.
