Problems solved by technology

This kind of computer tomography system is to detect the rotation of the object. Due to the high requirements on the relative position accuracy of the ray source, the detector and the rotation center and the accuracy of the mechanical movement, the host generally does not move after installation. Disadvantages such as difficult to adjust the accuracy, non-movable, and inability to carry out field testing in different places

Abstract

The invention discloses a vehicle-mounted movable detecting system for computed tomography (CT), and belongs to the technical field of nondestructive detection. The detecting system comprises a detecting car, an operating car, a power car, a CT annular scanning device, a workpiece bracket, safeguards and the like, wherein the CT annular scanning device provided with a shock absorber is mounted on the detecting car; a ray source and a detector are mounted on both sides of the central symmetry axis of a precise circle respectively, and are driven by the motor to realize the synchronous rotation, so as to conduct CT scanning on a workpiece. The detecting system has the advantages that the workpiece detected does not need to rotate, and CT scanning imaging of the workpiece is realized by the synchronous rotation of the ray source and the detector around the workpiece; the workpiece bracket is mounted on the detecting car, and is used for clamping and moving an detecting object; meanwhile, the detecting system further has the characteristics of being movable, easy to adjust, capable of implementing detection of remotely external fields and the like.

Description

technical field [0001] The invention belongs to the technical field of non-destructive testing, relates to a computer tomography detection technology, in particular to a vehicle-mounted mobile computer tomography (CT) detection system. Background technique [0002] Since the birth of the first industrial CT (computed tomography) system in the early 1980s, industrial CT systems have been widely used in various important industrial fields. [0003] Industrial CT (ICT for short), that is, Industrial Computed Tomography, is an advanced non-destructive testing method. It can intuitively, clearly and accurately present the internal characteristics of the measured workpiece through digital images without destroying the object. Features such as high rate. Commonly used scanning structures for industrial CT include vertical structures and horizontal structures, but these traditional industrial CT systems are installed in a reinforced concrete building or lead workshop that can shie...
