Non-destructive flaw detector for steel structure based on X-ray

Abstract

The invention discloses a non-destructive flaw detector for a steel structure based on the X-ray, which comprises a limiting and conveying device and a radiation ray detector. The limiting and conveying device comprises a conveying frame and a bearing plate. A feeding trough is fixedly mounted on the top of the conveying frame. A reclaiming tray and a feeding tray are arranged on the feeding trough from the left to the right, and are arranged on the conveying frame via a mounting frame. A plurality of separating cylinders are evenly mounted on the reclaiming tray. A protective dragging pad isfixedly mounted on the inner wall of the separating cylinder. A conveying motor is connected to the reclaiming tray and is fixedly mounted on the conveying frame. Reclaiming cylinders with a semi-circular cross section are fixedly mounted on the reclaiming tray. The protective dragging pad is also fixedly mounted on the inner wall of the reclaiming cylinder. The reclaiming tray is drivingly connected with the conveying motor. The non-destructive flaw detector for the steel structure based on the X-ray has a reasonable structure design, realizes the automatic continuous non-destructive flaw detecting of the steel structure, not only reduces the labor intensity of an operator, but also improves the efficiency of the non-destructive flaw detecting of the steel structure.

Description

technical field [0001] The invention relates to the technical field of nondestructive flaw detection, in particular to an X-ray-based nondestructive flaw detection device for steel bar structures. Background technique [0002] X-ray flaw detection refers to the use of X-rays to penetrate metal materials, and due to the different absorption and scattering effects of the materials on the rays, the film sensitivity is different, so images with different blackness are formed on the negative film, and the material is judged accordingly. A method of inspection for internal defect conditions. [0003] X-ray flaw detection is to use the difference in the degree of X-ray absorption of different thicknesses of materials, through the use of X-ray fluoroscopy and real-time imaging of industrial TV, to reveal the internal defects of materials, parts and welds from the film and imaging. Such as cracks, shrinkage cavities, pores, slag inclusions, incomplete fusion, incomplete penetration,...

AI Technical Summary

Problems solved by technology

[0005] In the existing non-destructive testing process of steel structure, the steel structure needs to be artificially transported to the detection structure, and the continuous non-destructive testing of the steel structure cannot be realized, which not only increases the work intensity of the operator, but also reduces the steel structure. The efficiency of non-destructive testing has certain defects
