Efficient X-ray nondestructive detector

Abstract

The invention discloses an efficient X-ray nondestructive testing instrument, and relates to a nondestructive detector, which aims to solve the technical problem that the detector in the prior art cannot detect the weld joints of pipelines with different pipe diameters, and adopts the technical scheme that the nondestructive detector comprises a ray mechanism, an imaging mechanism and a base, andthe ray mechanism and the imaging mechanism are respectively positioned on two sides of the pipeline and are arranged on the base; wherein a driving roller and an auxiliary roller which are used for supporting a pipeline are arranged on the base, the axis of the driving roller and the axis of the auxiliary roller are parallel to the axis of the pipeline, and a power assembly and a distance adjusting assembly are arranged on the base; depending on the diameter of a pipe, the distance adjusting assembly is used for adjusting the distance between the driving roller and the auxiliary roller, thenthe pipeline is placed on the driving roller and the auxiliary roller, the power assembly is used for driving the pipeline to roll, and then the ray mechanism and the imaging mechanism are used for detecting the pipeline, so that the pipeline can be detected, and weld joints of pipelines with different diameters can be detected.

Description

technical field [0001] The invention relates to a nondestructive testing instrument, more specifically, it relates to a high-efficiency X-ray nondestructive testing instrument. Background technique [0002] X-ray flaw detector is a kind of equipment that uses X-rays to penetrate substances and have attenuation in substances to find whether there are defects inside metal and non-metal materials and their products. Its working principle is to use X-rays to penetrate metal materials , and through the difference in the absorption and scattering of rays by the material, the film is sensitive to different light, so images with different blackness are formed on the negative film, and the internal defects of the material can be judged accordingly. [0003] The Chinese patent whose authorized notification number is CN206420793U discloses an X-ray digital non-destructive testing device for pipeline welds, including a ray mechanism, an imaging mechanism, a track mechanism and a transmi...

Problems solved by technology

[0004] When using the detection device in the prior art, install the two ends of the track mechanism on the pipeline, connect the X-ray machine mounting frame and the imaging mechanism with the track mechanism, put the X-ray flaw detector into the buckle, and then check the pipeline However, in practical applications, the diameter of the pipeline will be different, and the track mechanism of the detection device is composed of semi-orbit splicing with constant radius. When it is necessary to detect circular welds for pipelines with different diameters, this , it cannot be detected and needs to be improved
