Abstract
A radiation imaging train inspecting apparatus which can stride double-rail relates to the radiation imaging inspecting technique. The utility model comprises a radiation source, a corrector, a forward collimator, a back collimator and a detector boom provided with the detector array. The radiation source is installed on the base of one side of train track, and the front part of the radiation source is opposite to the corrector connecting with the base, the forward collimator and the back collimator in turn. The detector boom is installed on the vertical base of the other side of the train track. The structural characteristic is that the double-line rail is arranged between the detector boom and the back collimator. And the sector X ray emitted from the radiation source passes through the corrector, the forward collimator, the back collimator and any measured train on the double-line track, and then the sector X ray is opposite to the detector array in the detector boom. Compared with the prior art, not only the utility model is provided with small equipment investment, but also the utility model is provided with small ground occupying.
Description
Technical field
The utility model relates to the radiant image detection technique, and the radiant image that particularly can stride double track is applied to the testing fixture of train detection system.
Background technology
In the prior art, begin to have the drawing type container examination system to come out, as the van container detection system of German Heyman company and British Aerospace PLC's production from early 1990s.They are in a building can shield the sense channel of ray, fixed, as to produce sigmatron radiation source is housed and can receives the detector array that passes the container X ray, the vehicle that container will be housed with the driven equipment of special use dragged sense channel, when container passes through in X-ray beam, the X ray that sees through container is through in the detector, according to its Strength Changes, the Density Distribution of the object of adorning in the reflection case, and transmitted intensity is transformed into gradation of image, can obtain the fluoroscopy images of the object of adorning in the case.Continuous widespread use along with container examination system radiant image technology also is widely adopted in the train check system.In the train check system, checkout facility generally is installed on ground, and promptly radiation source is installed on track one side, and the detector jib is installed in the opposite side of track, and the application of radiation imaging technique promptly obtains the image of the object of adorning in the train body.Yet, for the train check system, the situation that two-wire is checked can appear on some circuits, promptly move different vehicles respectively on two different circuits.For the convenience of checking, two cover rolling stock testing fixtures need be installed respectively on two-wire, thereby cause the tremendous growth of equipment investment and the increase of floor area.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the purpose of this utility model provides a kind of radiant image train testing fixture of striding double track.Use it can reduce greatly train two-wire check system equipment investment, reduce floor area.
In order to reach above-mentioned goal of the invention, the technical solution of the utility model realizes as follows:
A kind of radiant image train testing fixture of striding double track, it comprises radiation source, corrector, preceding collimating apparatus, back collimating apparatus and the detector jib of detector array is housed.Described radiation source is installed on the pedestal of track for a train one side, before the radiation source successively over against the corrector that is connected with pedestal, preceding collimating apparatus and back collimating apparatus.Described detector jib is installed on the perpendicular pedestal of track for a train opposite side.Its design feature is to arrange the biserial track between described detector jib and the back collimating apparatus.The fan-shaped X ray that described radiation source penetrates by corrector, preceding collimating apparatus, afterwards can be behind the arbitrary tested train on collimating apparatus and the biserial track over against the detector array in the detector jib.
In above-mentioned testing fixture, the standard of described biserial track is the compound of two standard gauges or two broad gauges or standard gauge and broad gauge.
In above-mentioned testing fixture, described radiation source adopts linac or isotope.
Radiant image train testing fixture of striding double track provided by the utility model, owing to radiation source, corrector, preceding collimating apparatus and back collimating apparatus are installed in a side of train biserial track, the detector jib that detector array is housed is installed in the opposite side of train biserial track, thereby use a cover testing fixture, just can realize radiant image scanography the tested train of arbitrary row on the biserial track.Compare with prior art, the utility model not only equipment investment is little, also has the little advantage of floor area simultaneously.
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further.
Description of drawings
Accompanying drawing is a structure scheme of installation of the present utility model.
Embodiment
Referring to accompanying drawing, the utility model comprises the detector jib 6 that adopts linac or isotopic radiation source 2, corrector 3, preceding collimating apparatus 4, back collimating apparatus 5 and detector array is housed.Radiation source 2 is installed on the pedestal 1 of track for a train one side, before the radiation source 2 successively over against the corrector 3 that is connected with pedestal 1, preceding collimating apparatus 4 and back collimating apparatus 5.Detector jib 6 is installed on the perpendicular pedestal 7 of track for a train opposite side, arranges two standard gauges or two broad gauges or standard gauge and the compound biserial track 8 of broad gauge between detector jib 6 and the back collimating apparatus 5.The fan-shaped X ray that radiation source 2 penetrates by corrector 3, preceding collimating apparatus 4, afterwards can be behind the arbitrary tested train on collimating apparatus 5 and the biserial track 8 over against the detector array in the detector jib 6.
The utility model will avoid two row trains to cross in the checkpoint in use, and the method that can adopt is to adjust the train running timetable, staggers the time of train by the checkpoint; Or when two row trains may cross, preferential select to allow wherein a row train in advance, another row train slow down or stop by.When tested vehicle crosses the utility model device, the fan-shaped X ray that radiation source 2 penetrates passes with the preceding collimating apparatus 4 of its homonymy and back collimating apparatus 5 and the train that travels on arbitrary track and by the detector array of the detector jib that is arranged in biserial track 8 opposite sides and receives, and realizes the radiant image scanning of train is detected.
