Abstract

The present invention relates to the radiatio napplication in the detection of transport container and vay. The detection system consists of radiation source, radiation source hoister, collimator, support corbel, rolling guide, traveling crane, arced detector array, drivers, auxiliary guide, shielded detection room and the electronic weighing system. The traveling crane hoists the radiation source at its one end and one or two detector arrays at its other end. The traveling crane is driven by the drivers at two ends to move along the overhead guide and the auxiliary guide and to scan the tested immobile object for detection.

本发明的目的是提供一种图像高清晰、便于安装和维护、低运行成本、较少占地面积、探测机房整洁的大型客体在线无损工业探测系统。 Object of the present invention is to provide a high definition image, easy to install and maintain, low running cost, less floor space, clean room to detect large objects online industrial nondestructive detection system. 放射源1选装双射向放射源,申请的专利号为01123745.7,系统安装2个弧形探测器阵列7时,可得到双角度探测结果,从而对复杂重叠物品的图像进行三维合成。 An optional double radiation source toward the radiation source, the patent application No. 01123745.7, system installation two arcuate detector array 0700 dual-angle detection result is obtained, so that the image is a complex three-dimensional composite article overlap.

图1和图2为本发明的基本结构示意图,为了达到上述目的,本发明采用了如下设计技术方案,结合附图加以说明。 The basic structural diagram of FIG. 1 and 2 of the present invention, in order to achieve the above object, the present invention employs the following design scheme, will be described in conjunction with the accompanying drawings.

一种高架导轨行车式大型客体工业探测系统,主要应用于大型集装箱、航空集装箱和箱式货车的检测。 One kind of elevated rail trolley mounted large-scale industrial object detection systems, mainly used in large containers, detect aviation containers and box-type truck. 滚动导轨5和辅助导轨9高架安装于建筑屏蔽防护探测机房10内的支撑牛腿4上。 Rolling guide and the auxiliary guide rail 5 9 4 mounted on an overhead support 10 within the corbels detection protective shield building room. 行车6安装在滚动导轨5和辅助导轨9上。 Lane 6 is mounted on the rolling guide rails and the auxiliary guide rail 5 9. 在行车6的一端通过放射源吊装架2安装放射源1。 Lane 6 at one end by a radiation source the radiation source 12 the ceiling bracket. 准直器3吊装在放射源1和弧形探测器阵列7之间。 Hoisting collimator 3 between the radiation source 1 and the arcuate detector array 7. 行车6两端的驱动装置8同步驱动行车在导轨上运动,对静止不动的被检客体实施扫描,从而完成检测工作。 6 drive means driving across 8 driven synchronously driving movement on the rail, on stationary objects subject embodiment scan, thereby completing the inspection work. 采用高架行车式结构,便于系统的安装和维护,降低运行成本、减少占地面积,简洁探测机房。 Using overhead trolley structure, easy to install and maintain the system, reduce operating costs, reduce the area, room simple detection.

在地面安装电子称系统11,可对被检客体的重量进行计量,确认被检客体的重量和报关项目的内容是否相符。 In the ground-mounted electronic scale system 11, can be metered weight of the object to be inspected, confirm the contents of the seized objects weight and projects are consistent with the declaration.

采用滚动导轨使行车定位准确、无卡滞及振动现象、运行平稳,有力于提高检测图像质量。 A rolling guide the driving accurate positioning, no catching phenomenon and vibration, smooth running, powerful image quality to improve detection.

准直器3吊装在放射源1和弧形探测器阵列7之间,使得放射源1发出的射线经准直器3准直,挡掉无效的射线,使有效射线能够准确的被弧形探测器阵列7接收。 Hoisting collimator 3 between the radiation source 1 and the arcuate detector array 7, so that rays collimated radiation source 1 is emitted from the collimator 3, invalid block off the radiation, the effective radiation can accurately be arcuate probe 7 receives the array.

以放射源1为圆心的弧形探测器阵列7可以等距离的接收射线。 A radiation source in an arc centered detector array receiving radiation 7 may be equidistant. 并使射线垂直的射到探测器接收表面,有利于检测图像的采集和处理。 And radiation detector receives incident perpendicular to the surface, facilitate acquisition and processing detected image.

如图2所示,放射源1选装双射向放射源,系统安装2个弧形探测器阵列7时,可得到双角度检测图像,对复杂重叠物品进行三维图像合成,更有利于违禁物品或危险品的检查。 As shown, the radiation source a radiation source towards the two pairs of attachments, the system installed two arcuate detector array 0700 dual-angle detection images obtained, three-dimensional articles of complex overlapping image combining more conducive contraband or check the dangerous goods.
