技术领域
本公开涉及安检领域，具体涉及一种移动式辐射检查设备以及移动式辐射检查系统。
背景技术
目前，安检领域广泛使用扫描检查设备对被检测物进行扫描检测。根据扫描检查设备是否可以移动，将其划分为固定式扫描检查设备和可移动式扫描检查设备。固定式扫描检查设备包括射线源和探测器，射线源和探测器都安装在检测场地的设定位置，不可改变位置。需要检测时，将被检测物运输至检测场地，并置于射线源和探测器之间的检测通道内进行检测。可移动式扫描检查设备具有可以转场运输的优点，实际使用中，将可移动式扫描检查设备移动至被检测物所在的区域，以进行检测。
发明人发现，相关技术中至少存在下述问题：由于可移动式扫描检查设备需要转场运输，所以移动式扫描检查设备的设备参数，比如重量、尺寸等均需要满足运输要求。由于这些因素的限制，可移动式扫描检查设备所设置的射线源数量少，扫描模式比较单一。

具体实施方式
下面结合图1a～图4c对本公开提供的技术方案进行更为详细的阐述。
在介绍移动式辐射检查设备的技术方案之前，先定义各个方位。参见图1a至图1c，建立XYZ坐标系，其中X方向对应车辆的长度方向，Y方向对应车辆的宽度方向，Z方向对应车辆的高度方向。
参见图1a至图2c，本公开实施例提供一种移动式辐射检查设备，其包括车体1、行走机构2、臂架组件3、第一成像装置4以及第二成像装置5。车体1被构造提供支 撑。行走机构2安装于车体1，以带动车体1行走。
移动式辐射检查设备包括运输状态和检查状态。当移动式辐射检查设备处于运输状态，臂架组件3也是处于运输状态。当移动式辐射检查设备处于检查状态，臂架组件3也是处于检查状态。
车体1是移动式辐射检查设备的主体部分，用于设置驾驶室、车厢、底盘等。行走机构2可以为车轮、履带等多种实现方式。如果采用车轮，车辆的每个车轴的用于安装轮胎的端部都可以安装两个轮胎。
臂架组件3安装于车体1。臂架组件3被构造为在检查状态和运输状态之间切换；当臂架组件3处于运输状态下，臂架组件3被收缩至由车体1承载，进一步地，移动式辐射检查设备的全部部件均由自身承载运输、并不需要拆卸掉部分部件，也不需要借助其他的转场运输工具。当臂架组件3处于检查状态，臂架组件3展开后配合车体1的侧面共同形成检查通道。臂架组件3展开所需要的动力来自于移动式辐射检查设备自身，不用额外设置其他驱动机构来驱动臂架组件3变形。
臂架组件3的重量是移动式辐射检查设备总重量的重要组成部分。底盘的承载能力是确定的，如果臂架组件3过重，移动式辐射检查设备能够设置的成像设备的数量会受到限制。然而，如果臂架组件3过轻，则其承载能力会受到限制，这同样会使得影响成像设备的数量。可见，承载能力弱的臂架组件3，可能无法承载成像设备。承载能力强的臂架组件3，则又因为自身重量太重，使得移动式辐射检查设备的承载能力受限，仍然可能无法安装成像装置。为了解决这种矛盾，本申请的技术方案，一方面，对臂架组件3的材料进行了优化，臂架组件3的材质选用铝合金或者钛合金等轻便、且承载能力高的材料。另一方面，臂架组件3的各个臂架除了包括主梁外，还设置有加强肋等结构，以降低臂架组件3弯曲变形的风险。再一方面，臂架组件3的主梁可以采用多根型材并列布置，这种结构的主梁也具有比较高的抗弯性能。上述技术方案提供的车载式检查设备，能够满足行业法规对车辆关于重量、尺寸、底盘承载能力等方面的运输限制。
参见图1a至图2c，在一些实施例中，臂架组件3包括第一臂架31、第二臂架32和第三臂架33。第一臂架31、第二臂架32和第三臂架33的状态都可以切换。当臂架组件3处于运输状态，第一臂架31、第二臂架32和第三臂架33都位于车体1的顶部，随着车体1运输。当臂架组件3处于检测状态，第一臂架31、第二臂架32和第三臂架33展开、以在车体1的侧面形成检测通道P。无论是运输状态，还是检查状态， 都不需要将第一臂架31、第二臂架32和第三臂架33从车体1上拆卸下来，第一臂架31、第二臂架32和第三臂架33始终与车体1保持连接。这种设置方式，臂架组件3不需要反复拆装，且转场运输更加方便。
第一臂架31可升降地安装于车体1，第一臂架31具体安装于车体1的顶部。比如在车体1上设置升降驱动机构，升降驱动机构比如采用皮带驱动、齿轮驱动等方式。需要升起第一臂架31时，驱动机构带动第一臂架31相对于车体1伸出，使第一臂架31的顶部高于车顶，形成的检查通道的高度比较高，以满足大型、高承载的被检测物10的检查需求。或者，第一臂架31被构造可伸缩的。比如第一臂架31采用多节嵌套的臂节，需要扫描时，将臂节逐一伸出。第一臂架31包括伸出状态和回缩状态。当移动式辐射检查设备需要转场运输时，即臂架组件3处于运输状态，第一臂架31降落至全部位于车体1内部或者部分位于车体1内部，以缩短第一臂架31伸出车体1的高度，使得移动式辐射检查设备在转场运输过程中，车辆的高度尺寸满足道路法规对车辆的要求。
第二臂架32安装于第一臂架31，两者比如通过螺栓等紧固件固定连接。第一臂架31安装于后文介绍的回转平台92，通过回转平台92，带动第一臂架31、第二臂架32和第三臂架33同步相对于车体1回转。在检查状态下，第二臂架32作为检查通道的顶梁。上文介绍的第一成像装置4安装于第二臂架32。无论第二臂架32处于检查状态还是运输状态，第一成像装置4均与第二臂架32保持连接，两者之间的相对位置关系不变。在一些实施例中，第二臂架32包括梁321以及探测臂322，两者固定连接，以起到轻量、且保证承载能力的作用。探测臂322位于梁321的侧面。此处的侧面是以检查状态为例的，即探测臂322位于梁321沿着被检测物通过检查通道的方向上，具体采用图2b和图2c示意的探测臂322和梁321的相对位置。当臂架组件3处于运输状态，第一臂架31回收；第二臂架32和第一臂架31共同在回转平台92的驱动下转动至第二臂架32与车体1平行的位置，且位于车体1的顶部。当臂架组件3处于检查状态，第一臂架31伸出车体1的顶部，第二臂架32和第一臂架31共同转动，且第二臂架32大部分位于车体1外部。
第三臂架33可转动地安装于第二臂架32。参见图1c，处于运输状态下，第三臂架33处于折叠状态，第三臂架33位于第二臂架32的探测臂322下方，两者叠设在一起，第三臂架33和探测臂322叠设在一起的总高度与梁321的总高度基本相同，这样可以减少第二臂架32和第三臂架33在运输状态的高度，使得移动式辐射检查设 备的整体高度尺寸更小，更能满足转场运输的要求以及道路行驶要求。臂架组件3处于检查状态下，第三臂架33与第一臂架31是平行的，第三臂架33和第一臂架31分布于第二臂架32的两端。第一臂架31、第二臂架32和第三臂架33三者配合车体1，共同形成检查通道。
下面整体介绍臂架组件3在运输状态和检查状态的变化。
如图1a至图1c所示，当臂架组件3处于运输状态，第一臂架31回收；第二臂架32和第一臂架31共同转动至与车体1平行的位置，且位于车体1的顶部；第三臂架33转动至与第二臂架32平行的位置，且第三臂架33位于第二臂架32和车体1之间。
如图2a至图2c所示，当臂架组件3处于检查状态，第一臂架31伸出车体1的顶部，第二臂架32与第一臂架31垂直且第二臂架32的大部分位于车体1外侧，第三臂架33转动至与第二臂架32垂直且与第一臂架31平行的位置；第一臂架31、第二臂架32和第三臂架33在车体1的侧面形成检查通道，检查通道的位置如图2b和图2c所示。
继续参见图1a至图2c，在一些实施例中，移动式辐射检查设备还包括第一舱体7以及第二舱体8。第一舱体7和第二舱体8可以为封闭的舱体或者为敞口的舱体。是否封闭，取决于是否要求扫描射线穿过舱体的壁体。如果射线穿透舱体的壁体不影响、或者不太影响扫描检查效果，则舱体可以设置为封闭的。如果射线穿透舱体的壁体会比较明显地影响扫描检查效果，则舱体在射线的路径上需要设置为敞口的，以使得射线能够良好地完成扫描检测作业。
第一舱体7固定安装于车体1，具体比如采用螺栓连接等。在检查状态和运输状态下，第一舱体7相对于车体1的位置是固定的，两者之间不发生相对移动。
第二舱体8可转动地安装于车体1的尾部。其中，当臂架组件3处于运输状态，第二舱体8位于车体1的尾部；当臂架组件3处于检查状态，第二舱体8转动至车体1的侧面，第二舱体8和臂架组件3均位于车体1的宽度方向，且位于车体1的两侧。
在一些实施例中，车体1安装有回转机构9，第二舱体8安装于回转机构9，通过回转机构9带动第二舱体8转动，以实现第二舱体8在运输状态和检查状态之间切换。回转机构9包括回转支撑91和回转平台92。回转支撑91可转动地安装于车体1，回转平台92安装于回转支撑91，第二舱体8安装于回转平台92。外力驱动回转平台92和第二舱体8同步转动。
下面介绍各个辐射成像装置的布置方式。
参见图1a至图2c，如上文所述的，移动式辐射检查设备包括第一成像装置4和第二成像装置5。
第一成像装置4包括均安装于臂架组件3的第一射线源和第一射线探测器。第一射线探测器与第一射线源配合，以探测第一射线源发出的射线；第一射线源位于检查通道的顶部。第一成像装置4利用背散原理成像，其第一射线源和第一射线探测器都安装于被检测物的同一侧。参见图2c，以检查状态示意的方向为例，第一射线源和第一射线探测器都安装于臂架组件3的顶部，即第一成像装置4安装于第二臂架32，具体可以安装于第二臂架32的梁321。第一成像装置4用于从被检测物的顶部扫描。在一些实施例中，第一成像装置4为背散成像装置。第一射线源为背散射线源，第一射线探测器为背散射电子探测器。
参见图2b和图2c，第二成像装置5包括安装于车体1和/或臂架的第二射线源和第二射线探测器；第二射线探测器与第二射线源配合，以探测第二射线源发出的射线。第二射线源位于检测通道P的侧面。第二射线源和第二射线探测器其中之一安装于车体1，另一个安装于臂架组件3。具体地，第二射线源安装于车体1，第二射线探测器安装于臂架组件3的第三臂架33。第二成像装置5的靶点51的位置请参见图2c。在一些实施例中，第二成像装置5为透射成像装置，第二射线源为透射射线源，第二射线探测器为透射射线探测器。
在图2c中，虚线S1为第一成像装置4的射线路径。单点画线S2为第二成像装置5的射线路径。从图2c可以看出，第一成像装置4的射线不会完全穿透被检测物。第二成像装置5的射线则完全穿透被检测物。
继续参见图2b，第一成像装置4的第一射线源和第一射线探测器共同形成第一束面M1，第二成像装置5的第二射线源和第二射线探测器共同形成第二束面M2；第一束面M1和第二束面M2平行。这种设置方式，使得第一成像装置4和第二成像装置5的信号不会相互干扰，且实现了被检测物多种方式、多个角度的检测。
在一些实施例中，第一成像装置4和第二成像装置5是独立的，各自独立控制。第一成像装置4和第二成像装置5的启停、剂量控制、工作时间等参数都是单独控制的，相互之间不会影响。
在一些实施例中，第二射线源布置于第二舱体8中，第二射线探测器布置于臂架组件3的第三臂架33。或者，第二射线源布置于臂架组件3的第三臂架33，第二射线探测器布置于第二舱体8中。
在一些实施例中，根据第二射线源、第二射线探测器安装位置的不同，采用以下重量平衡方案，以保持移动式辐射检查设备在车辆宽度方向上的平衡：
第二射线源安装于第二舱体8，第二射线探测器安装于第三臂架33。第二舱体8、第二射线源的总重量与臂架组件3、第一成像装置4和第二射线探测器的总重量被配置为是平衡的，以使得移动式辐射检查设备在车体1的宽度方向上保持稳定。
第二种情况：第二射线源安装于第三臂架33，第二射线探测器安装于第二舱体8。第二舱体8、第二射线探测器的总重量与臂架组件3、所述第一成像装置4和第二射线源的总重量被配置为是平衡的，以使得移动式辐射检查设备在车体1的宽度方向上保持稳定。
在一些实施例中，第二舱体8的至少一侧被构造为开口的，以使得臂架组件处于检查状态时，位于第二舱体8内的第二射线源未经阻挡、直接射向被检测物10。
参见图3a至图4c，下面介绍一些其他的实施例。这些实施例与上述实施例的不同之处在于，在这些实施例中，移动式辐射检查设备除了设置有上文介绍的第一成像装置4和第二成像装置5之外，还设置有第三成像装置6。
与上述实施例相同的部分，比如车体1、臂架组件3的结构等，此处不再赘述，此处重点描述与第三成像装置6相关的内容。
参见图3a至图4c，在一些实施例中，移动式辐射检查设备还包括第三成像装置6，第三成像装置6包括安装于臂架组件3或者车体1的第三射线源和第三射线探测器。第三射线探测器与第三射线源配合，以探测第三射线源发出的射线；第三射线源位于检测通道P的侧面。在一些实施例中，第三成像装置6为背散成像装置，第三射线源为背散射线源，第三射线探测器为背散射电子探测器。
参见图4b，第一成像装置4的第一射线源和第一射线探测器共同形成第一束面M1，第二成像装置5的第二射线源和第二射线探测器共同形成第二束面M2，第三成像装置6的第三射线源和第三射线探测器共同形成第三束面M3；第一束面M1、第二束面M2和第三束面M3平行。
在图4c中，虚线S1为第一成像装置4的射线路径。单点画线S2为第二成像装置5的射线路径。双点画线S3为第三成像装置6的射线路径。从图4c可以看出，第一成像装置4的射线从上方扫描被检测物，且不会完全穿透被检测物。第二成像装置5的射线则从被检测物的侧面完全穿透被检测物。第三成像装置6的射线从侧面扫描被检测物，且也不会完全穿透被检测物。
在一些实施例中，第一成像装置4、第二成像装置5和第三成像装置6是独立的，各自独立控制。第一成像装置4、第二成像装置5和第三成像装置6各自的启停、剂量控制、工作时间等参数都是单独控制的，相互之间不会影响。
在一些实施例中，第三成像装置6布置于第一舱体7中。为了实现更好的扫描效果，第一舱体7的至少一侧被构造为开口的，以使得臂架组件处于检查状态时，位于第一舱体7内的第三射线源未经阻挡、直接射向被检测物10。
