Abstract
The present invention relates to the radiatio napplication in the detection of transport container and vay. The detection system consists of radiation source, radiation source hoister, collimator, support corbel, rolling guide, traveling crane, arced detector array, drivers, auxiliary guide, shielded detection room and the electronic weighing system. The traveling crane hoists the radiation source at its one end and one or two detector arrays at its other end. The traveling crane is driven by the drivers at two ends to move along the overhead guide and the auxiliary guide and to scan the tested immobile object for detection.
Description
The present invention relates to the radioactive source radiation application, be overhead guide rail running vehicle type checkout equipment.Be mainly used in the detection of van container, air container and motor van etc.
The present invention mainly comprises radioactive source, collimating apparatus, curved detector array, driving, rolling guide, auxiliary guide rail and drive unit.The fan-ray beam that is produced by radioactive source collimates through collimator slit, a transversal section of the tested object of its transmission, by the curved detector array received they, be transformed into view data.When native system under motor-driven during with uniform motion, beam will scan a series of transversal section of object successively, finally form fluoroscopy images.
The purpose of this invention is to provide a kind of image high-resolution, be convenient to installation and maintenance, low operating cost, less floor area, survey the clean and tidy online harmless industrial detection system of large object of machine room.The dijection of radioactive source 1 choosing dress is to radioactive source, and the patent No. of application is 01123745.7, when 2 curved detector arrays 7 are installed by system, can obtain two angle detection results, synthesizes thereby the image of the overlapping article of complexity is carried out three-dimensional.
Fig. 1 and Fig. 2 are basic structure synoptic diagram of the present invention, and in order to achieve the above object, the present invention has adopted following design technology project, is illustrated in conjunction with the accompanying drawings.
A kind of overhead guide rail running vehicle type large object industrial detection system is mainly used in the detection of van container, air container and motor van.On rolling guide 5 and the auxiliary guide rail 9 overhead support brackets 4 that are installed in the architectural shielding protection detection machine room 10.Driving 6 is installed on rolling guide 5 and the auxiliary guide rail 9.End in driving 6 is installed radioactive source 1 by radioactive source mast-up 2.Collimating apparatus 3 is lifted between radioactive source 1 and the curved detector array 7.The drive unit 8 driven in synchronism driving at 6 two ends of driving a vehicle is moved on guide rail, actionless tested object is implemented scanning, thereby finish testing.Adopt overhead running vehicle type structure, be convenient to the installation and maintenance of system, reduce operating cost, reduce floor area, succinctly survey machine room.
In floor mounted electronic scale system 11, can measure the weight of tested object, confirm whether the weight of tested object and the content of declaration project conform to.
Adopt rolling guide to make driving accurate positioning, no clamping stagnation and oscillation phenomenon, operate steadily, effectively in improving the detected image quality.
Collimating apparatus 3 is lifted between radioactive source 1 and the curved detector array 7, and the ray that makes radioactive source 1 send collimates through collimating apparatus 3, and retaining falls invalid ray, and effective rays can be received by curved detector array 7 accurately.
With radioactive source 1 is that the curved detector array 7 in the center of circle can equidistant reception ray.And make ray vertical be mapped to the detector receiving surface, help the collection and the processing of detected image.
As shown in Figure 2, radioactive source 1 choosing dress dijection when 2 curved detector arrays 7 are installed by system, can obtain two angular detection images to radioactive source, the overlapping article of complexity is carried out 3-D view synthesize, and more helps the inspection of prohibited items or dangerous material.
