The scanning vehicle is characterized in that a rotatable tray is arranged on a bracket of the scanning vehicle, and a portal frame formed by a vertical support frame, a horizontal cantilever provided with a detector and a vertical cantilever is arranged on the tray. When in detection, the control vehicle is far away from the detection site and controls the portal frame to parallelly cross the detected container. The detection result is displayed on the control vehicle, and the separate work of the person and the equipment with the X-ray is realized. Compared with the prior art, the utility model has the characteristics of reasonable in design, detection speed are fast, the formation of image figure is clear, do not harm the person.
Description
The utility model relates to a kind of autoscan formula large-sized object radiation detecting apparatus, particularly mobile container pick-up unit.Belong to the radiation checking technical field.It is used to be suitable for customs's detection van container.
Movable container inspectino apparatus is one of checkout equipment of customs's urgent need, does not still have this series products at home at present.External existing mobile container pick-up unit product all is to adopt control device part and scanister part are installed on a car.Be that operating personnel and all checkout equipments all must be to carry out work on same car.Because the people does with turner with the equipment of band X ray, if the ray energy height of radiation source, it is very difficult that then shielding problem becomes, for this reason can only be with X-ray machine as radiation source.Because the ray energy of X-ray machine is low, penetrability is poor, mainly by the backscattering imaging.So the part that image can be seen more clearlyly only limits to the interior object apart from tank wall 20～30 cm range of container one side.The picture quality and the scope of application far can not satisfy most users' of customs requirement.Exist that inspection speed is slow, resolution is low, the ropy shortcoming of image forming.Also have employing to make radiation source with cobalt 60 in the external like product, the radioactivity of its radiation source can not the people produce for stopping, be that the physical property of itself determines.Therefore it exists the possibility that radioactive element leaks, and security performance is bad, can cause direct harm to the person.
In order to overcome the shortcoming that exists in the above-mentioned prior art, the purpose of this utility model provide a kind of security good, to the person do not have harm, inspection speed is fast, resolution is high, the image forming Functionality, quality and appealing design be the two-truck mobile container pick-up unit of radiation source with the accelerator.
In order to reach above-mentioned goal of the invention, technical solutions of the utility model realize as follows: the two-truck mobile container pick-up unit that with the accelerator is radiation source, it comprises electron linear accelerator and two carrier loaders, and a car is a scanning car, and another car is the control car.Be characterized in, rotating pallet is installed on the body bracket of described scanning car.The hinged perpendicular bracing frame of forming with four-bar mechanism on the pallet.Tranverse connecting rod extends to the horizontal boom that detector is housed on the perpendicular bracing frame.The horizontal boom other end is provided with the hydraulic tensioning oil cylinder, and the vertical cantilever that the stretching oil cylinder will be equipped with detector is connected with horizontal boom and can makes vertical cantilever perpendicular or parallel in horizontal boom.Described electron linear accelerator also is located on the above-mentioned pallet, and its X ray is vertical cantilever and the horizontal boom after vertical all the time.Be provided with radio communication apparatus, scan control module and image collection module on the scanning car in addition.The feeder cable that described control car is provided with radio communication apparatus, rolling inspection device and can joins with scanning car, power supply can be with civil power or generating voluntarily on the control car.When detected set is cased, pallet on the scanning car rotates 90 degree, form portal frame by perpendicular bracing frame, horizontal boom, vertical cantilever, send control signal by the radio communication apparatus on the control car, radio communication apparatus on the scanning car receives control signal and by the scan control module portal frame that forms on the scanning car is driven by scanning car itself, strides across detected container and does parallel moving.The X ray that electron linear accelerator is emitted passes tested container, after the reception of the detector in horizontal boom and the vertical cantilever, convert electric signal input picture acquisition module to, image collection module with picture signal be transported to again control on the car the rolling inspection device and show measured result by graphoscope.
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.
According to above-mentioned technical scheme, the front end of described scanning car is equipped with angle sheave mechanism.Angle sheave mechanism comprises web joint, back up pad and angle sheave, web joint can be connected with the scanning car front bottom end, the back up pad vertical fixing is movably hinged the parallel four-bar mechanism consistent with each other of two covers, the lower supporting rod bottom suit angle sheave of each four-bar mechanism on the back up pad on web joint.Be fixed on the lifting that hydraulic jack on the scanning car is controlled each angle sheave by a set end, when each angle sheave lands, can be with the front-wheel jack-up of scanning car, by each angle sheave of rear wheel drive of scanning car by default track walking.
The utility model is owing to adopted two cars, and one is scanning car, and another is the control car.To the radiation source of the harmful band X ray of the person be placed on the scanning car, and the people works in the control car.So fundamentally solved the problem of X ray to human body harm.Because to adopt with the electron linear accelerator be radiation source, the X ray energy that it produced is more much bigger than X-ray machine again for the utility model, thereby its penetration power to container strengthens greatly, has improved inspection speed and resolution, makes the shaping image very clear.It is radiation source with the electron linear accelerator that employing is arranged again, in case the outage then can not produce any radiation.Compare with prior art, the utlity model has reasonable in design, structure is ingenious, installation is easy, easy to use, detection speed fast, shaping picture quality height, the person do not had the characteristics of any harm.Be the indispensable equipment that van container detects in customs.
The utility model will be further described below in conjunction with accompanying drawing and concrete embodiment.
