技术领域
本公开涉及扫描检查技术领域，尤其涉及一种移动式检查设备和移动式检查方法。
背景技术
目前，辐射扫描检查已经广泛应用于医疗卫生、国民经济和科学研究等领域。在海关、港口等场所，也可以利用辐射扫描检查设备对车辆的车载货物进行检查，检查过程中不需要开箱，大大提高了检查效率。
扫描检查设备通常设置在固定的位置，车辆拉载着被检物10通过扫描通道实现检查。但是，在有些场所不适合长期布置固定不动的检查设备，因此车载式移动检查设备应运而生。车载式移动检查设备在扫描检查时，先将支撑架展开形成扫描通道，然后再开始扫描检查。由于检查设备随车携带，为了便于展开扫描检查，检查设备一般安装在车辆底盘的后端，造成后轴承重较大，局部应力太大容易引起部件损伤和故障。而且，底盘车的主轴通常很长，容易超出道路行驶要求，安全性也较差。
需要说明的是，公开于本公开背景技术部分的信息仅仅旨在增加对本公开的总体背景的理解，而不应当被视为承认或以任何形式暗示该信息构成已为本领域技术人员所公知的现有技术。

具体实施方式
下面将结合本公开实施例中的附图，对实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本公开的一部分实施例，而不是全部的实施例。基于本公开的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开的描述中，需要理解的是，术语“中心”、“横向”、“纵向”、“前”、“后”、“左”、“右”、“上”、“下”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开保护范围的限制。
参考图1～15所示，在本公开提供的移动式检查设备的一些实施例中，该检查设备包括移动体100、支撑组件、射线源5、探测器13和第一驱动装置4，移动体100可移动地设置，支撑组件安装在移动体100上，且支撑组件被配置为在移动式检查设备的运输状态相对于移动体100缩回，并在移动式检查设备的检查状态相对于移动体100伸出；射线源5和探测器13均安装在支撑组件上，第一驱动装置4被配置为驱动支撑组件相对于移动体100转动，以使射线源5和探测器13在收回位置和工作位置之间进行切换，在运输状态时射线源5和探测器13位于收回位置，在检查状态时射线源5和探测器13位于工作位置。
在上述实施例中，支撑组件能够相对于移动体100伸缩，在检查状态时，支撑组件伸出，以方便支撑组件相对于移动体100转动，将射线源5和探测器13旋转至工作位置；而在运输状态时，支撑组件缩回，以缩短移动式检查设备的整体长度，满足道路行驶要求，同时有利于提高运输过程中的安全性。
将支撑组件设置为可以相对于移动体100伸缩的结构，移动体100的重心位置前移，这样可以使后桥载荷减小，从而改善车桥受力情况，提高检查设备整体的平稳性。
在一些实施例中，在收回位置，第一驱动装置4被配置为驱动射线源5和探测器13运动至沿移动体100的移动方向布置的位置。这样设置便于使射线源5和探测器13收回至移动体100范围内，防止运输过程中与其他物品发生干涉或碰撞。
在工作位置，第一驱动装置4被配置为驱动射线源5和探测器13分别运动至移动体100的两侧。这样设置便于使射线源5和探测器13相对展开，并在射线源5和探测器13之间形成检测通道，便于实施检查。射线源5和探测器13分别位于移动体100的两侧，还可以实现移动体100两侧的配重平衡，避免移动体100发生倾翻。
在一些实施例中，射线源5和探测器13设置于在收回位置使射线源5的靶点11和探测器13的安装平面位于第一平面的同一侧的位置，第一平面与移动体100的移动方向相互平行且经过支撑组件的旋转中心。这样设置的好处是，在射线源5和探测器13从收回位置运动至工作位置时，使射线源5和探测器13正好处于相对的位置， 便于探测器13接收到射线源5发射的射线，而不需要再专门调整，有利于节省调整时间，提高检查效率。
在一些实施例中，支撑组件包括第一支撑件3和第二支撑件12，射线源5安装在第一支撑件3上，探测器13安装在第二支撑件12上，第一支撑件3和第二支撑件12均与第一驱动装置4驱动连接。
通过设置两个单独的支撑件，可以分别对射线源5和探测器13独立地进行支撑，便于分别进行结构设计。
在一些实施例中，第一支撑件3和第二支撑件12相互连接为一体，这样便于第一驱动装置4驱动第一支撑件3和第二支撑件12一起转动。这样可以使第一支撑件3和第二支撑件12的运动保持同步，进而使射线源5和探测器13的转动保持同步。
在另一些实施例中，第一支撑件3和第二支撑件12之间保持相对独立，第一支撑件3和第二支撑件12能够发生相对运动。这样便于第一驱动装置4分别驱动第一支撑件3和第二支撑件12相对独立地转动，进而根据需要实时调节射线源5和探测器13之间的相对位置，满足检查需求。
在第一驱动装置4分别驱动第一支撑件3和第二支撑件12相对独立地转动的实施例中，第一驱动装置4可以包括用于驱动第一支撑件3转动的第一驱动件和用于驱动第二支撑件12转动的第二驱动件。第一驱动件和第二驱动件的结构可以相同，也可以不同。
第一驱动装置4可以采用回转平台等旋转驱动元件。
在一些实施例中，第一支撑件3包括延伸至移动体100之外的悬臂部，射线源5安装于悬臂部。用于支撑射线源5的悬臂部悬挂于移动体100的后侧，且位于移动体100之外，这样设置便于在射线源5旋转至工作位置时使射线源5和探测器13之间形成检查通道，避免射线源5和探测器13之间存在其他部件影响射线的传输，影响检查质量。
在一些实施例中，第一支撑件3包括第一支撑部31和第二支撑部32，第一支撑部31与第一驱动装置4驱动连接，第二支撑部32相对于第一支撑部31可动，以调节第一支撑件3的长度。
例如，第一支撑部31相对于移动体100保持固定，第二支撑部32相对于第一支撑部31可伸缩，以便调节第一支撑件3的长度，进而调节支撑组件的长度以及检查设备的整体长度。
在一些实施例中，支撑组件还包括第二驱动装置33，第二驱动装置33与第二支撑部32连接以驱动第二支撑部32相对于第一支撑部31运动。第二驱动装置33可以采用油缸、气缸或者电动推杆等。
第二驱动装置33与第二支撑部32之间还可以设置齿轮链条或者齿轮齿条等传动机构，实现动力的传递。
在一些实施例中，支撑组件还包括设置于第一支撑部31和第二支撑部32之间的导向件，导向件用于对第二支撑部32的运动进行导向。
通过设置导向件，可以对第二支撑部32的运动进行导向，使第二支撑部32沿着预设的路线运动，提高运动的准确性和可靠性。
在一些实施例中，导向件包括导轨34，第一支撑部31的宽度大于或小于第二支撑部32的宽度，第二支撑部32与第一支撑部31之间通过导轨34滑动配合。
如图16和图17所示，第一支撑部31的宽度小于第二支撑部32的宽度，第二支撑部32沿导轨相对于第一支撑部31伸缩。
如图18和图19所示，第一支撑部31的宽度大于第二支撑部32的宽度，第二支撑部32沿导轨相对于第一支撑部31伸缩。
导轨可以采用两组轨道相互配合的结构，也可以采用轨道与滑块相互配合的结构，这里不再详述。
在其他实施例中，第一支撑部31和第二支撑部32之间也可以采用滚动配合，比如在第一支撑部31和第二支撑部32之间设置滚动轴承等。
在一些实施例中，移动式检查设备还包括第一舱体1，第一舱体1安装在移动体100上，第二支撑件12包括第三支撑部7和第四支撑部6，第一驱动装置4设置于第一舱体1内，第三支撑部7与第一驱动装置4驱动连接，在运输状态第四支撑部6支撑于第一舱体1的顶部。
通过设置第一舱体1，可以保护安装于移动体100上并位于第一舱体1内部的部件。而且，第一舱体1的顶部还可以在运输状态时对第四支撑部6进行支撑。
比如，第二支撑件12包括竖直设置的第三支撑部7和水平设置的第四支撑部6，第四支撑部6与第三支撑部7连接。第三支撑部7为竖向可伸缩的结构，在检查状态时，第三支撑部7竖向伸长，在运输状态时，第三支撑部7竖向缩短，以使第四支撑部6可以支撑于第一舱体1的顶部。
第二支撑件12还可以包括第一探测臂8和第二探测臂9，第一探测臂8沿水平方 向布置并安装在第四支撑部6的侧面。第二探测臂9与第一探测臂8可转动地连接，在运输状态，第二探测臂9相对于第一探测臂8折叠，第二探测臂9转动至与第一探测臂8相互平行的位置，且第二探测臂9位于第一探测臂8的下方；在检查状态，第二探测臂9相对于第一探测臂8展开，第二探测臂9转动至与第一探测臂8相互垂直的位置，第一探测臂8、第二探测臂9、第三支撑部7和第四支撑部6一起形成可折叠的门式框架，竖直设置的第三支撑部7和第二探测臂9之间形成检查通道。
第一探测臂8和第二探测臂9上均设置有探测器13，用于接收射线源5发射的射线。
在其他实施例中，第二支撑件12也可以采用其他可行的结构。
在一些实施例中，移动式检查设备还包括第二舱体2，第二舱体2安装在第一支撑件3上，射线源5设置在第二舱体2内。第二舱体2上设置有与射线源5的出射口对齐的通孔，以方便射线射出。
通过设置第二舱体2，可以有效保护射线源5。同时，第二舱体2与第一舱体1一起形成整个检查设备的舱体。
在一些实施例中，射线源5的一部分设置于第二舱体2的内部，另一部分设置于第二舱体2的外部。例如，射线源5设置于第二舱体2的底部，射线源5的下部从第二舱体2的底部露出，这样既可以保护射线源5，也不会影响射线源5的射线出射。
在一些实施例中，在运输状态第一舱体1和第二舱体2相互接触，避免第一舱体1和第二舱体2之间出现缝隙，影响美观。
其中，第一舱体1和第二舱体2相互接触，可以是第一舱体1的后侧面和第二舱体2的前侧面整体都相互接触，也可以是仅仅第一舱体1的左右两侧板和第二舱体2的左右两侧板实现部分相互接触。
在一些实施例中，在运输状态第一舱体1和第二舱体2之间具有预设间隙。该间隙可以方便第二舱体2的转动，在制造上也比较容易实现。
在一些实施例中，第一舱体1的靠近第二舱体2的侧面与移动体100的靠近第二舱体2的侧面之间具有预设距离，即第一舱体1并未设置于移动体100的边缘，该预设距离使得在移动体100的靠近第二舱体2的一端形成了凸出部14，第二舱体2的靠近第一舱体1一侧的下部设有凹入部15，这样在运输状态时凸出部14嵌入凹入部15中，凹入部15正好搭接在移动体100的后侧，使得移动体100可以对第二舱体2起到部分支撑作用。
在一些实施例中，移动体100包括车辆底盘。车辆底盘的底部设有多个车轮，可以相对于地面行走。车轮设置在移动体100的底部，第二舱体2的底部未设置车轮，支撑组件伸出后，第二舱体2的底部悬空。
下面结合附图1～15对本公开移动式检查设备一个实施例的工作过程进行说明：
以下将以移动体100的移动方向作为参考方向进行描述，移动体100朝向的方向为前，背离的方向为后。
首先，如图1-3所示，在运输状态时，支撑组件旋转至与移动体100移动方向相互平行的方向，第一支撑件3在后，第二支撑件12在前。第一支撑件3中的第二支撑部32相对于第一支撑部31缩回(例如参照图16、图18)，第二舱体2的前侧面与第一舱体1的后侧面紧密接触。第二支撑件12中的第二探测臂9可转动地设置于第一探测臂8的下方，第三支撑部7竖直下降，第四支撑部6、第一探测臂8和第二探测臂9支撑于第一舱体1的顶部。
接着，如图4-6所示，第二驱动装置33驱动第二支撑部32相对于第一支撑部31向后伸出，第二舱体2离开第一舱体1，检查设备进入第一中间状态，此时第二支撑件12仍保持不动(例如参照图17、图19)；
然后，如图7-9所示，第二支撑件12中的第三支撑部7竖直上升，第四支撑部6、第一探测臂8和第二探测臂9均离开第一舱体1的顶部，检查设备进入第二中间状态；
然后，如图10-12所示，第一驱动装置4驱动支撑组件相对于移动体100发生旋转，支撑组件旋转至与移动体100的移动方向相互垂直的方向，射线源5和探测器13分别位于移动体100的两侧，检查设备进入第三中间状态；
最后，如图13-15所示，第二探测臂9相对于第一探测臂8展开，第二探测臂9旋转至竖直方向，在第三支撑部7与第二探测臂9之间形成检查通道，射线源5发射的射线照射在被检物10上，经被检物10投射或反射的射线被探测器13接收，实现对被检物10的扫描检查。通过分析探测器13接收的信号，可以判断被检物10中是否包含违禁物。
在一些实施例中，可以在第一驱动装置4驱动支撑组件相对于移动体100发生旋转，支撑组件旋转至与移动体100的移动方向相互垂直的方向，射线源5和探测器13分别位于移动体100的两侧之后，第二支撑件12中的第三支撑部7竖直上升，第四支撑部6、第一探测臂8和第二探测臂9均离开第一舱体1的顶部。
在另一些实施例中，可以在第二驱动装置33驱动第二支撑部32相对于第一支撑 部31向后伸出的同时，第一驱动装置4驱动支撑组件相对于移动体100发生旋转，伸出和旋转同时进行并结束。同样，缩回和旋转也可以同时进行并结束。
本公开还提供了一种移动式检查方法，该方法包括：
提供可移动的移动体100和安装在移动体100上的支撑组件；
使、支撑组件相对于移动体100伸出；
伸出后，通过第一驱动装置4驱动支撑组件相对于移动体100转动，以使射线源5和探测器13从收回位置转动至工作位置；
启动射线源5和探测器13，对待检查对象进行扫描检查；
检查完成后，通过第一驱动装置4驱动支撑组件相对于移动体100转动，以使射线源5和探测器13从工作位置返回收回位置；
然后，使支撑组件相对于移动体100缩回。
上述各个实施例中移动式检查设备所具有的积极技术效果同样适用于移动式检查方法，这里不再赘述。
最后应当说明的是：以上实施例仅用以说明本公开的技术方案而非对其限制；尽管参照较佳实施例对本公开进行了详细的说明，所属领域的普通技术人员应当理解：在不脱离本公开原理的前提下，依然可以对本公开的具体实施方式进行修改或者对部分技术特征进行等同替换，这些修改和等同替换均应涵盖在本公开请求保护的技术方案范围当中。
