Abstract
A removable cantilever gantry crane container checking apparatus relates to a radiation scan imaging check technical field, which comprises a movably scan equipment formed with a radiation source, a scanning frame formed by detectors and a remote control apparatus. The utility model had a structural character that the radiation source or an equipment storehouse equipped with the radiation source is connected with an L-shaped cantilever structure to form a gantry frame. Rollers which are capable of back and forth motion on an orbit are equipped under the radiation or the equipment storehouse equipped with the radiation source and the rollers are controlled by a drive device. The detectors are positioned in a beam and an upright beam of a gantry frame cantilever structure and radials of the radiation source are just faced with various ranges of detectors in the gantry frame cantilever structure. Detected container trucks are capable of passing through a door case formed by the gantry frame. The utility model is designed into a cantilever structure to make the checking system has the advantages of stable movement, excellent imaging quality and high reliability or the like.
Description
Technical field
The utility model relates to radiation scanning imaging inspection technical field, particularly a kind of movable boom door type container testing fixture.
Background technology
In order to tackle the terrorist activity that the whole world is becoming increasingly rampant, countries in the world are all being strengthened the entry and exit goods especially to the safety inspection of container truck.Usually by the harbour, customs etc. locate to smuggle dangerous material to the terrorist, as: explosive, gun etc., this will cause great threat to national security.By the detection of radiation scanning imaging system, can stop the generation of above-mentioned phenomenon to a great extent.The characteristics of such check system are to need the beam with special scanister emission carry out radiation monitoring to tested truck, carrying radiation source and detector on the scanister, and the to-and-fro movement by scanister scans tested truck.The ray that radiation source sends sees through tested truck and passes to detector, and detector reflects the Density Distribution of inspected object according to the variation of transmitted intensity, and transmitted intensity is transformed into gradation of image, can obtain the fluoroscopy images of tested truck.
In the prior art, this class radiation image-forming system has following several mode implementation: fixed, and combination moving type, vehicle-mounted removables etc., the utility model belong to the combination moving type radiation image-forming system.The Chinese patent of the applicant's application, as the patent No. is that 00103342.5 " a kind of movable container inspectino apparatus of dismantled and assembled combination " and the patent No. are that 99126240.9 " a kind of mobile container examination system capable of being combined " all is to be similar on the structure of door case type and to load radiation source and detector being across tested truck both sides, on two footing of door case type structure wheel is housed, makes the scanister to-and-fro movement finish scanning by the drive unit wheels.Use in the engineering, this implementation has following defective: owing to the gate-type structural span that is across tested truck both sides is bigger, to having relatively high expectations of scanister integral rigidity, brought very big difficulty for manufacturing and designing of scanister.Need to improve the integral rigidity of scanister.Simultaneously, the increase of span makes the wheel of whole scanister both sides in operational process be difficult to synchronous operation, makes to impact the operation smoothness not of whole scanister to radiant image.In addition, because wheel is equipped with in the mounting structure of detector side below, the vibration between wheel and the rail also can exert an influence to picture quality.
Summary of the invention
In order to overcome the defective that exists in the above-mentioned prior art, the purpose of this utility model provides a kind of movable boom door type container testing fixture.It improves on the basis of original gate-type structure and is designed to cantilever design, check system is had operate steadily, characteristics such as good imaging quality, reliability height.
In order to reach above-mentioned goal of the invention, the technical solution of the utility model realizes as follows:
A kind of movable boom door type container testing fixture, it comprises the scanning support be made up of radiation source, detector and remote control thereof and forms portable scanning device.Its design feature is that the equipment compartment that described radiation source or radiation source placed is connected with L type cantilever design and forms the gate-type frame.The equipment compartment that radiation source or radiation source placed has can reciprocating in orbit roller, and each roller is by driving device controls.Detector places among the crossbeam and vertical beam of gate-type frame cantilever design, and the ray of radiation source is respectively arranged detector in the gate-type frame cantilever design.Pass through in the doorframe that tested container truck can be formed by the gate-type frame.
In above-mentioned movable boom door type container testing fixture, the crossbeam of described gate-type frame middle part is by perpendicular stent support.
In above-mentioned movable boom door type container testing fixture, the bottom of described perpendicular support is provided with roller.
In above-mentioned movable boom door type container testing fixture, described drive unit is motor driver or driving device for hydraulic motor.
In above-mentioned movable boom door type container testing fixture, described radiation source adopts linac or isotope.
The utility model is owing to adopted above-mentioned structure, adopted cantilever design in the double track outside, reduced the span of gate-type structure effectively, greatly reduced requirement scanister rigidity, manufacturing and designing of scanister is more prone to, and the reliability of system also improves greatly.Because the span of gate-type structure reduces, the degree of operating steadily of whole scanister can improve greatly.Simultaneously, detector is installed in cantilever design one side, makes that the vibration of wheel and rail is very little to the influence of picture quality.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
