Multifunctional X-ray channel type CT/DR detection device

Abstract

The invention discloses a multifunctional X-ray channel type CT/DR detection device. The multifunctional X-ray channel type CT/DR detection device comprises a detection transmission line, a lead protection channel covering the detection transmission line, a lead protection door arranged on one side of the lead protection channel, a lead curtain suspended on two ends of the lead protection channel, an X-ray machine arranged at the top of the inner part of the lead protection channel, a linear array detector corresponding to the top and the bottom of the X-ray machine and arranged at the bottom of the inner part of the lead protection channel, a workpiece mounting base arranged inside the lead protection channel, in front-back correspondence to the lead protection door and used for mounting, moving and rotating the workpieces, a CT scanning mechanism arranged on the workpiece mounting base and a field operation table connected with the X-ray machine, the workpiece mounting base and the CT scanning mechanism and used for controlling the workpieces to scan, image and move. According to the multifunctional X-ray channel type CT/DR detection device, a DR moving mechanism and a CT moving mechanism capable of independently running are respectively mounted inside the detection device and are capable of respectively running according to the requirement, so that DR and CT functions can transform and make an organic combination.

Description

[0001] Technical field [0002] The present invention relates to the technical field of non-destructive testing (non-destructive testing, non-destructive testing), quality testing and research and judgment equipment, and in particular to an X-ray channel type CT / DR (CT: Computed Tomography, DR: Digital Radiography, Digital X-ray photography) multifunctional testing equipment. [0003] Background technique [0004] At present, the main structure and principle of the technology (equipment) used for non-destructive inspection of products are: transilluminate the workpiece through the X-ray device, convert it into a digital signal by the imaging system, and then restore it to an image file by computer software, and then conduct quality research and judgment. , Marking, storage and other operations. [0005] Practice shows that the existing such equipment has obvious problems and shortcomings: [0006] The equipment has a single function, which can only be used for planar scan (DR) or tom...

AI Technical Summary

Problems solved by technology

[0006] The equipment has a single function and can only be used for planar scanning (DR) or tomographic scanning (CT), which cannot balance efficiency and precision, because CT has high precision but low detection efficiency; DR has high efficiency but low precision

[0007] Basically, it is customized by industry (or according to the workpiece). Generally, it can only meet the quality inspection and judgment of specific products or specific industries. The scope of application is relatively narrow, and it cannot adapt to changes in the specifications, shapes, materials (density) and other factors of the workpiece. Due to this limitation , if a new process is introduced or a new workpiece is detected, new equipment needs to be purchased separately, and the procurement and manufacturing costs, management and maintenance costs will all increase accordingly, and the cost of site and space will also increase

[0008] DR or CT imaging share a set of motion mechanism, random inspection or full inspection, different requirements for efficiency and accuracy, and functional conversion cannot be taken into account
