Description

Technical Field

[0001] The utility model relates to the field of an anti-scattered ray mechanism of an X-ray machine for non-destructive flaw detection of pipelines, and more specifically to an anti-scattered ray mechanism of an X-ray machine for non-destructive flaw detection of pipelines. Background Art

[0002] Pipeline flaw detection uses a radiographic flaw detection method to check whether the internal quality of the weld of the pipeline welding joint is qualified. The rays pass through the material to reach the film, which will make the film evenly sensitive to light. If there are defects such as cracks, holes, bubbles and slag inclusions, a dark shadow area will appear on the film. This method can detect the size and shape of the defects and can also measure the thickness of the material. The existing pipeline flaw detection X-ray machine has an anti-scattering ray mechanism, which will cause blurred photosensitivity when the external light is strong, reducing work efficiency. In addition, the intensity of the rays will decay during the process of penetrating the pipeline, and the focusing is poor, so it cannot achieve the best use effect, and needs focusing and shading;

[0003] For example, in the prior art patent, such as the authorization announcement number CN219066437U discloses an anti-scattered ray mechanism of a pipeline flaw detection X-ray machine, which relates to the technical field of X-ray machines and includes a fixed seat, wherein the upper and lower ends of the fixed seat are fixedly connected with connecting plates, and the outer wall of the fixed seat is fitted with a rubber sleeve, and the outer wall of the rubber sleeve is penetrated by a sleeve, and the outer wall of one end of the sleeve is installed with a card seat, and the outer wall of the card seat is installed with a shading component, and the inner wall of the card seat is installed with a focusing component. Through the mutual cooperation of the shading plate and the adjustment hand wheel, the shading plate can block the external light, and the position angle of the shading plate is adjusted by using the adjustment hand wheel, which solves the problem that the photosensitivity is blurred when the external light is strong, thereby reducing the work efficiency;

[0004] The focusing assembly in the above-mentioned patent adopts a convex lens to focus light, but adopts a fixed structure. The focusing distance cannot be precisely adjusted when focusing light, and cannot be accurately adjusted. The shading assembly of the prior art patent includes a shading plate, and the shading plate is installed on the outer wall of the shading assembly, and an adjustment hand wheel is installed on the left side of the shading assembly. The shading plate is specifically arc-shaped, and the edge of the shading plate is specifically concave. The shading assembly adopts a shading plate structure distributed at the upper end, and its shading is not comprehensive. Utility Model Content
