Abstract
The utility model relates to a radiation source-collimator-detector integrated structure of a container scanning device, which comprises a radiation source, a collimator and a detector. The utility model is characterized in that the radiation source is installed on a rotatable tray. The tray is additionally hinged with a vertical supporting frame which is composed of four connecting rods. A transverse connecting rod on the vertical supporting frame is extended to be a horizontal cantilever which is provided with a detector. The other end of the horizontal cantilever is connected with a vertical cantilever. The horizontal cantilever and the vertical cantilever are over against the X-rays which is sent out by the radiation source. The collimator is arranged between the vertical cantilever and the radiation source. With the utility model, stochastic detection can be done when the source-collimator-detector integrated structure of a container scanning device moves at other places. Therefore, the investment of fixed detection areas is saved.
Description
The utility model relates to the architecture advances of the scanister of customs used container examination system, particularly container examination system.
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 the beginning of the nineties.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 passes 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.This detection system, its sense channel length needs 60 meters at least, and each 40 meters at least of length are taken up an area of at outside two ends, are very huge dragging systems, and floor area is equivalent to a football field.Adopt the shortcoming of this detection system scanister to be, it is big to take up an area of site area, the cost of investment height.The more important thing is that it has seriously hindered the development of rigid container test format to the mobile container test format, can not fundamentally solve and take up an area of the problem that the space is big, cost of investment is high.The strange land that can not realize pick-up unit is in addition moved container is carried out with machine testing.
In order to solve above-mentioned problems of the prior art, the purpose of this utility model provides a kind of radiation source-collimating apparatus-detector integral structure that is applicable to the container scanning device that customs is detected.Use it can accomplish that not only the strange land movable random detects, do not take fixing detection space, and the investment that can save the fixed test place.
In order to reach above-mentioned goal of the invention, the technical solution of the utility model realizes as follows: the radiation source-collimating apparatus of container scanning device-detector integral structure, it comprises radiation source, play the collimating apparatus of X ray shielding action and the detector of reception X ray, its design feature is, described radiation source is installed in an end above the rotating pallet, the hinged perpendicular bracing frame of forming with four-bar mechanism of the other end above the pallet, the last tranverse connecting rod of perpendicular bracing frame extends to the horizontal boom that detector is housed, the horizontal boom other end is provided with the hydraulic tensioning oil cylinder, the vertical cantilever that the stretching oil cylinder will be equipped with detector is connected with horizontal boom and can makes vertical cantilever be vertical or parallel to horizontal boom, vertical cantilever after vertical and horizontal boom be the X ray of emitting of the radiation source above being installed in pallet all the time, and described collimating apparatus also is located at above the pallet, between vertical cantilever and the radiation source.
According to above-mentioned technical scheme, be provided with between the outer vertical connecting rod of the described perpendicular bracing frame of forming with four-bar mechanism and the lower transverse connecting rod and it can be propped up or tilted-putted hydraulically extensible oil cylinder.
The utility model has been owing to adopted above-mentioned structure type of attachment, will former fixed detection frame or survey tower, be installed on the rotating pallet with the form of four-bar mechanism, pallet again can with car body or mobile platform binding, and can rotate.So the horizontal boom of band detector and vertical cantilever can be rotated at pallet and be launched to form the gantry frame type scan arm on the certain position again.Again because the X ray that the radiation source installed on pallet penetrates, by after the collimating apparatus all the time over against horizontal boom and vertical cantilever, so no matter pallet is installed on the movable car body or on the platform, do not influence scanning and carry out.Thereby the utility model can use easily in any position and occasion.Can realize not taking fixing detection space, save and detect the place investment, accomplish that pick-up unit strange land movable random detects.Compare with prior art, the utlity model has reasonable in design, easy to use, for ease of maintenaince, characteristics that cost of investment is low.
Below in conjunction with accompanying drawing and concrete embodiment the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is user mode figure of the present utility model.
Referring to Fig. 1 and Fig. 2, the radiation source-collimating apparatus of container scanning device-detector integral structure comprises that with electron linear accelerator or isotope be radiation source 2, the collimating apparatus 3 that plays the X ray shielding action and the detector that receives X ray.Radiation source 2 is installed in an end above the rotating pallet 1, the hinged perpendicular bracing frame of forming with four-bar mechanism 5 of the other end above the pallet 1, the last tranverse connecting rod of perpendicular bracing frame 5 extends to the horizontal boom 6 that detector is housed, horizontal boom 6 other ends are provided with hydraulic tensioning oil cylinder 7, and the vertical cantilever 8 that stretching oil cylinder 7 will be equipped with detector is connected with horizontal boom 6 and can makes vertical cantilever 8 be vertical or parallel to horizontal boom 6 places.Vertical cantilever 8 after vertical and horizontal boom 6 be the radiation source over against being installed in pallet 1 above 2 X ray of emitting all the time, erects to be provided with between the outer vertical connecting rod of bracing frame 5 and the lower transverse connecting rod and it can be propped up or tilted-putted hydraulically extensible oil cylinder 4.Described collimating apparatus 3 also is located at above the pallet 1, between vertical cantilever 8 and the radiation source 2.
When using the utility model, be installed in its pallet 1 on the carbody that can travel or movably on the platform.During detection, pallet 1 rotates counterclockwise 90 degree, will erect bracing frame 5 by hydraulically extensible oil cylinder 4 and prop up.Portal frame by perpendicular bracing frame 5, horizontal boom 6 and vertical cantilever 8 form strides across tested container.Prolong tested container by car body itself or mobile platform drive portal frame and do parallel moving.Control the utility model autoscan by the control system that other establishes.
