Description
Technical Field
The utility model relates to a fixture equipment field, specifically speaking relates to an industry CT is with centimetre level long column rock scanning anchor clamps.
Background
The working principle of the industrial CT is as follows: when the X-ray is incident on the object, a part of the X-ray is absorbed, a part of the X-ray is scattered, and a part of the X-ray is transmitted through the object. If the detected object is uniform and has no difference in structure, the transmitted X-ray intensity is uniform; if the detected object is not uniform or has structural difference, it will change the uniformity of X-ray projection to make it non-uniform. The detector is used for detecting the intensity of the transmitted X-ray, and the structural difference, the size and the property of the detected object can be displayed. In general, the higher the density of the object to be detected, the higher the detected tone value, and the lower the density of the object to be detected, the lower the detected tone value.
An X-ray tube and a detector of Nikon XTH225ST industrial CT are fixing devices, an object to be detected needs to be fixed on a clamp to rotate 360 degrees when the instrument conducts three-dimensional scanning, the X-ray tube emits X-rays, the X-rays are received by the detector after passing through a sample, a series of X-ray images are obtained, and then the three-dimensional structure of the scanned object is restored. The CT scanning magnification factor is equal to the distance between a ray tube and a detector divided by the distance between a sample and the ray tube, the distance between the ray tube and the detector is assumed to be A, the distance between the sample and the ray tube is assumed to be B, and the sample scanning magnification factor = A/B. For the same detected object, the more centered the position of the detected object on the fixture, the smaller the rotation radius obtained during rotation, the closer the sample is to the ray tube, and the higher the scanning accuracy obtained, therefore, the shape and the nature of the fixture often determine the accuracy and the quality of the scanning data.
The use of CT technology in geological research is increasing, such as in the fields of petrology, mineralogy and ancient biology, where it is becoming common to use this method for rapid, non-destructive inspection of internal structures. In the above studies, one type of centimeter-sized long cylindrical rock samples is involved, such as natural and synthetic crystals, common drill cores, vertebrate coprocessed rock and the like. For scanning of the long columnar rocks, the rocks are directly stuck on a Nikon CT clamp with a metal rod by a conventional means through hot melt adhesive. This type of scanning has the following drawbacks:
1. the clamp is made of a steel rod and has high density; the detected object is generally siliceous and calcareous and has low density. On the display of an X-ray image, the two have larger gray value difference, the gray value displayed by the metal rod clamp is far higher than that of the detected object, and the structure of the joint of the clamp and the detected object cannot be effectively distinguished; meanwhile, the clamp and the detected object have large gray value difference, so that subsequent rock structure observation and the like are troubled.
2. When manually sticking the hot melt adhesive for the rock on the top end of the metal rod clamp, the manual sample sticking is corrected by naked eyes, so that the rock core is hardly guaranteed to be in a vertical state for sample loading. If the core is adhered to the fixture in an inclined shape, the rotation radius of the core is increased, the distance between the sample and the ray tube is increased, and the scanning resolution is reduced.
3. With hot melt adhesive rock, the sample is easily damaged when it is mounted and dismounted, especially when the centre position is corrected.
