Description
Technical field
The utility model relates to radiation scanning imaging detection technology field, especially for the collimation and the correcting integrating device of container check system.
Background technology
The core component of container check system is to produce the radiation source of sigmatron and receive the detector array that passes the container X ray.Container by X-ray beam by the time, the X ray that sees through container passes in the detector, according to its Strength Changes, institute's object density of adorn distribution in the reflection case, and transmitted intensity become gradation of image can obtain the Density Distribution of the interior object of adorning of case.At present, container check system comprises fixed container inspecting system, vehicle-mounted removable container check system and combination moving type collection wiring check system etc.In above-mentioned all types of container check systems, the ray that radiation source sends need be proofreaied and correct and collimate.The corrector of prior art and collimating apparatus all are to make a covering device respectively separately, place the front of radiation source successively, and position in use and angle also need to adjust respectively.Because it is bigger that two covering devices take up room in equipment, and very heavy.Particularly in the combination moving type container check system, because the general employing of radiation source is linac, and accelerator generally need be placed in the body of cabin, and the design of the inner space in the body of cabin is as far as possible little, adopt existing corrector and collimating apparatus in use just to seem very difficult like this, give and install, adjust and bring inconvenience.
Summary of the invention
At above-mentioned problems of the prior art, the purpose of this utility model provides a kind of collimation and correcting integrating device that is used for container check system.Correcting block plays corrective action when using it to do correction test, and correcting block and collimation piece are formed collimating apparatus jointly and played collimating effect during normal inspection.Have volume little, in light weight, be convenient to install, characteristics easy and simple to handle.
In order to realize above-mentioned goal of the invention, the technical solution of the utility model realizes as follows:
The collimation and the correcting integrating device that are used for container check system, it comprises collimation piece, correcting block, servomotor, be connected with the servomotor output terminal and by the leading screw of two bearing seats supports.Servomotor and each bearing seat are fixed on the base plate, and the nut with its coupling is housed on the leading screw.Its design feature is that described collimation piece and correcting block gap are arranged to be installed in and formed one-piece construction on the fixed head.Be equipped with supporting plate below the fixed head, the both sides of supporting plate are equipped with slide plate, and the middle part of supporting plate is equipped with web joint, and slide plate places on the guide rail of base plate both sides setting, and web joint and described nut are fixed.When servomotor starts, drive nut by leading screw and make collimation piece and correcting block on the fixed head whole mobile.
In above-mentioned integrated device, described collimation piece is a collimating slit that gap width is consistent with assemblage gap between the correcting block.
In above-mentioned integrated device, be equipped with rolling bearing or sliding bearing in the described bearing seat.
In above-mentioned integrated device, be equipped with between described base plate and the guide rail and reinforced and the channel-section steel of adjusting function of height.
In above-mentioned integrated device, contour shape and guide rail cross section outer contour shape coupling is slidingly matched for the gap between the two in the cross section of described slide plate.
The utility model will collimate piece and correcting block integral installation on fixed head owing to adopted above-mentioned structure, reduce the volume of original two covering devices greatly.Move together by servomotor control fixed head, can satisfy the technical requirement of detection system proofreading and correct and collimating.Compare with prior art, the utility model has been saved installing space and has also been alleviated weight of equipment.In the use, correcting block is finished the function of correction, and the intermediate gap that collimation piece and correcting block form realizes the function of ray collimation, and the adjustment of single unit system is more easy with control.
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to the user mode synoptic diagram.
Embodiment
Referring to Fig. 1, the utility model device comprises collimation piece 1, correcting block 2, servomotor 4, be connected with servomotor 4 output terminals and by the leading screw 5 of two bearing seats, 13 supports that are equipped with rolling bearing or sliding bearing.Servomotor 4 and each bearing seat 13 are fixed on the base plate 15, and the nut 8 with its coupling is housed on the leading screw 5.Collimation piece 1 arranges to be installed on the fixed head 3 with correcting block 2 gaps and forms one-piece construction, and collimation piece 1 is a collimating slit 9 that gap width is consistent with assemblage gap between the correcting block 2.Be equipped with supporting plate 11 below the fixed head 3, the both sides of supporting plate 11 are equipped with slide plate 12, and the middle part of supporting plate 11 is equipped with web joint 10.Slide plate 12 places on the guide rail 6 of base plate 15 both sides setting, and contour shape and guide rail 6 cross section outer contour shapes couplings between the two for the gap is slidingly matched, has been equipped with between base plate 15 and the guide rail 6 and has reinforced and the channel-section steel 14 of adjusting function of height in the cross section of slide plate 12.Web joint 10 is fixed with described nut 8, when servomotor 4 starts, drives nuts 8 by leading screw 5 and makes the collimation piece 1 on the fixed head 3 whole mobile with correcting block 2.
