Problems solved by technology
However, during the operation, due to the small size of the lead characters, it is difficult to install and remove the lead characters, and the work efficiency is low
At the same time, the lead characters are pasted on the adhesive tape, which is prone to fall off during use, which makes the lead characters incomplete and lost.

Embodiment Construction
[0024] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only the technical solutions of the present invention. Some, but not all, embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.
[0025] like Figure 1 to Figure 4 As shown, the present invention provides an X-ray inspection auxiliary tool for installing a film, and the auxiliary tool is installed on the pipeline and makes the projection of the welding seam on the film. The irradiation directions of the film, the weld seam and the X-ray flaw detector are on the same straight lin...

The invention discloses an X-ray detection auxiliary tool, comprising a shading bag and a marking assembly arranged on the shading bag. The shading bag is used for containing a film, the marking assembly comprises a mounting plate, a lead word diaphragm and a pressing plate, a plurality of mounting grooves are formed in the mounting plate at intervals in the length direction of the mounting plate, the first end of the lead word diaphragm is inserted into the mounting groove, the second end of the lead word diaphragm extends to the outside of the mounting groove, and the pressing plate is movably arranged on the mounting plate and used for pressing the second end of the lead word diaphragm on the mounting plate. The multiple mounting grooves are formed in the mounting plate at intervals, the first ends of the lead word diaphragms are inserted into the mounting grooves, and the second ends of the lead word diaphragms are pressed on the mounting plate through the pressing plate. According to the structure, the lead characters can be conveniently installed and taken down, the lead characters can be prevented from falling off and being lost, and the X-ray detection auxiliary tool has the advantages of being convenient to operate, high in working efficiency and long in service life.
Description
technical field [0001] The invention relates to the technical field of non-destructive testing equipment, in particular to an X-ray testing auxiliary tooling. Background technique [0002] In the field of thermal power generation, since pipelines operate under high temperature and high pressure, X-ray inspection is required after pipeline welding is completed to ensure that the weld seams of pipelines meet the standard requirements. The principle of X-ray inspection is: to irradiate the weld seam of the inspected pipeline by X-ray flaw detector, and to find the defects of the weld seam by using the characteristics of X-ray penetration and attenuation in the material. A film for imaging is placed on one side of the pipeline. After the film is developed, fixed, washed and dried, the image of the pipeline and the weld seam will appear on the film, and then the existence of the weld seam can be judged by identifying the weld seam image. Quality defects. In the actual productio...
