具体实施方式
以下详细说明本公开。在以下段落中，更为详细地限定了实施例的不同方面。如此限定的各方面可与任何其他的一个方面或多个方面组合，除非明确指出不可组合。尤其是，被认为是优选的或有利的任何特征可与其他一个或多个被认为是优选的或有利的特征组合。

在本公开的描述中，采用了“上”、“下”、“顶”、“底”、“前”、“后”、“内”和“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，而不是指示或暗示所指的装置必须具有特定的方位、以特定的方位构造和操控，因此不能理解为对本公开保护范围的限制。
发明人所知晓的相关技术中，对于大型的安全检查装置，在运输时需要将安全检查装置的各个部件拆散，例如臂架、舱体、探测器、射线源等，再到作业现场重新安装和调试。而且现场需要重新搭建防护墙以及进行防护墙的土建工作，耗费时间较长，且需要较大的人力投入。因此，安全检查装置在需要转运时操作较为繁琐，而且受到多次重复安装的影响，也不容易保证安全检查装置的检测精度。
有鉴于此，本公开提供了一种安全检查装置及转场方法，能够提高安全检查装置 在需要转运到不同场所使用时的便捷性。
本公开一些实施例的安全检查装置，设有轮胎使安全检查装置整体于地面灵活地进行移动，通过将臂架、第一舱体和防护墙设置为在连接状态下一起运输，在安全检查装置需要转场时，无需将各关键部件拆散，也省去了在检查现场重新安装和调试的环节，可缩短拆卸时间，提高转场效率；另外，还能避免在检查现场重新搭建防护墙和进行防护墙土建工作，使安全检查装置被运输到检查现场后能够很快投入工作。这些优点都能大大缩短安全检查装置从运输到投入工作所耗费的时间，提高转场效率，提高使用便捷性，减少人力投入。
如图1至图4所示，本公开提供了一种安全检查装置，在一些实施例中，包括：臂架1、第一舱体3、防护墙2和轮胎4。其中，臂架1上设有多个探测器11，臂架1设置为例如L形或门形等，用于形成检查通道A。第一舱体3内部设有射线源，并与臂架1连接。防护墙2与第一舱体3或臂架1连接，用于对待防护对象进行射线防护。轮胎4设在安全检查装置底部，用于带动安全检查装置相对于地面整体发生移动。例如，可在第一舱体3沿检查通道A延伸方向靠近两侧的位置分别设置一个轮胎4，轮胎4可通过支架5进行安装。
在需要进行扫描检查时，待检物沿着检查通道A的长度方向相对于臂架发生相对运动，射线源发射出的射线穿过待检物被探测器11接收，通过对探测器11接收的信息进行分析，可以判断待检物是否符合安全标准。
由于安全检查装置设有轮胎4，安全检查装置可灵活地在场地内移动，无需像固定式或轨道式安全检查装置一样需要进行土建，而且能使安全检查装置的移动更加顺畅和平稳，还可实现转弯，运动轨迹可自由选择。
在预设范围的场地内，如果需要对处于不同区域的待检物进行检查，可以使安全检查装置依次运动至待检查物聚集的区域，以对该区域内的待检物进行检查。或者也可以保持安全检查装置位置不动，通过各类车辆或传送装置携带待检物依次通过安全检查装置。在检查过程中，待检物与臂架1发生相对运动即可，可以是待检物单独运动、臂架1单独运动或者同时运动。
在工作状态下，臂架1、第一舱体3和防护墙2连接在一起，在运输状态下，臂架1、第一舱体3和防护墙2被设置为在连接状态下一起运输。此种安全检查装置至少具备如下优点之一：
(1)在安全检查装置需要转场时，无需将各关键部件拆散，也省去了在检查现 场重新安装和调试的环节，可缩短拆卸时间，提高转场效率，提高使用便捷性，减少人力投入。
(2)在运输时，安全检查装置的各部件连接在一起，且处于同一辆运输设备上，在涉及多个安全检查装置的运输时，无需进行标记或配套。
(3)能够避免在检查现场重新搭建防护墙和进行防护墙土建工作，使安全检查装置被运输到检查现场后能够很快投入工作，从而大大缩短安全检查装置从运输到投入工作所耗费的时间。
(4)将安全检查装置的各部件连接在一起运输，在新的场地中使用时无需重新安装调试，可保证安全检查装置的检测精度。
在一些实施例中，轮胎4可拆卸地设在第一舱体3的底部。通过将轮胎4设置为可拆卸的方式，如果在运输时轮胎4超出了安全检查装置其它部件的外廓，则可以将轮胎4拆下以进一步缩小安全检查装置的整体体积，降低运输时对车辆尺寸要求。如果轮胎4的设置位置不影响运输尺寸，可以不拆除轮胎4整体进行运输。而且，将轮胎4拆下后运输，在运输设备行驶时，安全检查装置不容易发生移动，可提高运输稳定性，防止出现安全隐患。
在一些实施例中，如图2所示，在检查通道A的延伸方向上，轮胎4在安全检查装置的工作状态下超出第一舱体3的侧部，轮胎4在安全检查装置的运输状态下拆卸。
该实施例允许增大轮胎4之间的支撑间距，以提高安全检查装置工作和移动过程中的稳定性。对于这种结构，在运输时将轮胎4拆下，可减小轮胎4设置位置对安全检查装置整体运输尺寸的影响，降低运输时对车辆尺寸要求，并提高运输安全性。
在一些实施例中，在检查通道A的延伸方向上，臂架1和第一舱体3之间的相对位置在安全检查装置的运输状态和工作状态保持不变。该实施例能够使设置臂架1上的探测器11与设置在第一舱体3上的射线源的相对位置在运输状态和工作状态保持不变，节省在检查现场需要对探测器11和射线源的相对位置进行重新调试的时间，使安全检查装置从运输设备上卸下来之后能够更快地投入检查工作。
在一些实施例中，如图4所示，防护墙2相对于臂架1可收合地设置，用于在安全检查装置的工作状态下展开以对待防护对象进行射线防护，并在安全检查装置的运输状态下收回，以缩短防护墙2在检查通道A的延伸方向上的长度。
该实施例能够在运输时不拆除防护墙2，只将防护墙2收回以减小其在检查通道A的延伸方向上占用的空间。安全检查装置放在运输设备上时，检查通道A的延伸方 向与运输设备的宽度方向一致，垂直于检查通道A的方向与运输设备的长度方向一致。当运输设备为运输车辆时，由于一般运输车辆车厢的容纳体积一般受限于宽度尺寸，因此将防护墙2收回可减小对运输车辆宽度的要求。另外，也可减小安全检查装置的整体运输体积，易于运输，提高运输稳定性。
在运输状态，防护墙2位于辐射探测装置内部和贴合于第一舱体3中的至少一个位置。在对被检物如集装箱、车辆等进行检查时，使防护墙2展开以防止射线泄漏，提高在辐射检查时的安全性，在不需要进行检查时，如转场运输或存放时，改变防护墙2墙体的位置以减小安全检查装置的整体占用的空间，方便安全检查装置的整体运输，且存放时占地面积较小。由于安全检查装置可以整体运输或存放，还利于减少再次使用时的安装调试工作，利于安全检查装置快速做好检查准备。
仍参考图4，在检查通道A的延伸方向上，防护墙2在收回的状态下不超出第一舱体3的侧部。此种结构能够最大限度地减小安全检查装置在在运输设备宽度方向所占用的空间。
在一些实施例中，防护墙2在水平面内可转动地设置，能够在安全检查装置的运输状态下向内收回。例如，将防护墙2的一端可转动地与臂架1或第一舱体3连接，另一端可自由转动。此种结构易于实现，无需占用臂架1等其它部件的内部空间。
可替代地，防护墙2也可以设计为多段伸缩的方式，在需要对待防护对象进行射线防护时伸出，并在运输状态下可缩回。
在一些实施例中，防护墙2设有两组，两组防护墙2分别位于臂架1沿在水平面内垂直于检查通道A延伸方向的两侧，每组防护墙2包括两个平行设置的防护墙2，能够朝着检查通道A的中线折叠实现收回。在工作状态下，每个防护墙2都可展开至平行于检查通道A的延伸方向的状态。
如图1所示，臂架1呈门式结构，臂架1包括两个竖臂13和连接在两个竖臂13顶部的横臂12，检查通道A形成于两个竖臂13之间，如图2所示，上述的“检查通道A的延伸方向”为垂直于臂架1所在平面的方向，“检查通道A的中线”为与检查通道A的延伸方向相互平行且位于两个竖臂13之间的中间线位置。
此种安全检查装置的防护墙2形成对称结构，既能提供较好的防护效果，也能减小防护墙2展开后占用的空间，方便运输。
具体地，防护墙2包括第一防护段、第二防护段和连接件，第一防护段和第二防护段通过连接件可活动地连接，第二防护段能够相对于第一防护段朝着检查通道A的 中线折叠。
在一些实施例中，如图2和图4所示，在检查通道A的延伸方向上，第一防护段设置在第一舱体3的前后两个侧面之间，第二防护段至少部分地设置在第一舱体3的前侧面或后侧面以外，且折叠后第二防护段位于第一舱体3的前后两个侧面之间。
此种结构可以使防护墙2在折叠后能够全部地折叠至第一舱体3的前后两个侧面之间的空间内，使整个安全检查装置在前后方向上的宽度与第一舱体3的宽度大致相等，尽量减小整个安全检查装置的宽度，方便运输。
在设计防护墙2时，第二防护段的长度的二倍等于或大于臂架1的两个竖臂13之间的横向距离。在第二防护段的长度的二倍等于臂架1的两个竖臂13之间的横向距离时，左右两侧的第二防护段分别向内折叠后正好对上，像两扇门一样将检查通道A关闭；在第二防护段的长度的二倍大于臂架1的两个竖臂13之间的横向距离时，左右两侧的第二防护段分别向内折叠后可以前后相互交叠，这样既可以通过折叠达到减小安全检查装置前后宽度的目的，又可以具有较大的射线防护范围。
在一些实施例中，在检查通道A的延伸方向上，防护墙2的横截面的高度朝着远离臂架1的方向逐渐减小。这样设置可以在尽量实现全面防护的前提下尽量减小防护墙2的体积，减轻安全检查装置的整体重量。
在一些实施例中，安全检查装置还包括锁止结构，锁止结构用于将处于第一舱体3一侧的两个防护墙2保持在一起，或者用于将各防护墙2与第一舱体3或后续提到的第二舱体3’保持在一起。第一锁止结构例如采用卡扣结构、插销结构、绳索、链条等。
在一些实施例中，臂架1在高度方向上可升降地设置，被配置为在安全检查装置的工作状态下升高以形成检查通道A，并在安全检查装置的运输状态下降低收回。
例如，臂架1呈门式结构包括横臂12和分别连接在横臂12两侧的两个竖臂13，两个竖臂13设置为多级箱式结构嵌套的方式实现伸缩；或者采用导轨结构实现伸缩。通过采用伸缩结构，降低了安全检查装置在运输过程中的高度，方便了安全检查装置的运输。
该实施例可以在运输时通过使臂架1在高度方向上收回而降低整个安全检查装置的高度，符合运输要求；而且安全检查装置的重心降低后，在运输过程中不容易随路面的颠簸出现晃动，可提高运输的安全性。
如图3所示，臂架1能够在安全检查装置的运输状态下收回至不超出第一舱体3 的高度或者道路行驶的最大限制高度。此种设置方式能够最大限度地降低安全检查装置在运输时沿高度方向的尺寸，使安全检查装置在高度方向的尺寸取决于第一舱体3的高度，可提高运输的稳定性，并保证道路行驶的安全性。
可选地，防护墙2的高度被设置为小于或等于第一舱体3的高度。这样设置可以在运输时使整个安全检查装置的高度与第一舱体3的高度大致相等，尽可能地减小整个安全检查装置的高度，避免超出道路运输时对车辆的高度限制。
在一些实施例中，探测器11包括设置于横臂12上的第一探测部和相对于横臂12位置可变的第二探测部，在检查状态，第二探测部位于检查通道A的一侧，在运输状态，第二探测部设置于横臂12上。该设置利于探测器11适应检查状态和运输状态，可以在不影响探测器11功能的情况下，防止探测器11影响辐射检查设备在检查状态和运输状态切换。
例如，在检查状态，第二探测部可以竖直地位于检查通道A的一侧，也可以与竖直方向具有一定夹角；在运输状态，第二探测部与第一探测部沿检查通道的延伸方向或竖直方向并排地设置于横臂12上，且第二探测部与第一探测部的延伸方向均沿横臂12的延伸方向一致。
在一些实施例中，第二探测部可以与第一探测部铰接，第二探测部通过绕第一探测部转动改变与横臂12的相对位置。在另一些实施例中，第二探测部可以与臂架1铰接，第二探测部通过绕臂架1转动改变与横臂12的相对位置。例如，第二探测部可以与横臂12铰接，也可以与竖臂13铰接。第二探测部铰接于第一探测部或臂架1上，利于辐射检查设备在检查状态和运输状态之间快速时探测器11快速、准确就位，从而缩短辐射检查设备切换的时间，且利于检查状态时探测器11处于准确的探测位置。
第二探测部与第一探测部或臂架1的连接关系不限铰接，例如，在检查状态和运输状态，第二探测部还可以可拆卸地连接于相应的位置。
在一些实施例中，臂架1在水平面内垂直于检查通道A的延伸方向上长度可调，即横臂12设计为可伸缩的形式以实现长度可调。在转场时，臂架1在垂直于检查通道A的延伸方向上缩回，第一舱体3和第二舱体3’相互靠近，可进一步缩小安全检查装置的体积，降低对运输车辆长度的要求。
如图1所示，本公开的安全检查装置还可包括第二舱体3’，臂架1呈门式结构包括横臂12和分别连接在横臂12两侧的两个竖臂13，第一舱体3和第二舱体3’分 别与两个竖臂13连接。这样设置可以使整个结构具有更好的对称性，结构布置更加合理。
第二舱体3’可以采用与第一舱体3相同的规格，这样可以保证整个安全检查装置的外观比较美观。可替代地，第二舱体3’也可以选择与第一舱体3不同的规格，可选地，第二舱体3’的尺寸小于第一舱体3的尺寸，以减小整个安全检查装置的重量。
第一舱体3和第二舱体3’可以采用具有外罩的封闭式结构，有利于保护内部结构，还可以防止沙尘进入舱体内的部件，外观也比较美观；第一舱体3和第二舱体3’也可以采用框架式结构，以减轻整体重量。
可选地，第一舱体3被配置为在安全检查装置的工作状态下相对于地面固定地设置，在一些实施例中整个安全检查装置相对于地面固定设置。在工作状态，安全检查装置保持不动，被检物相对于安全检查装置移动，以完成扫描检查。这样设置可以简化安全检查装置的结构，不需要在第一舱体3上安装行走装置，这对于安全检查装置的运输和安装也更加方便，效果更高。
结合图3和图4所示，在较理想的情况下，安全检查装置在收合防护墙2和臂架1，并拆下轮胎4后，整体形成长方体，极大地缩小了沿检查通道A延伸方向的尺寸，从而减小在运输设备宽度方向占用的空间，易于运输，并提高了运输时的稳定性。该安全检查装置可以在运输状态和工作状态简单切换，现场无需安装调试，具有自防护功能，可将关键部件整体运输，无需土建。
其次，本公开还提供了一种基于上述实施例安全检查装置的转场方法，在一些实施例中，包括：
在臂架1与第一舱体3连接，且防护墙2与第一舱体3或臂架1连接的状态下，将臂架1、第一舱体3和防护墙2一起运输实现转场。
在一些实施例中，在运输之前此种转场方法还包括：
将轮胎4从第一舱体3上拆下，可将支架5随轮胎4一同拆下。
在一些实施例中，在运输之前，此种转场方法还包括：
将防护墙2收回，以缩短防护墙2在检查通道A的延伸方向上的长度。
在一些实施例中，在运输之前，此种转场方法还包括：
将臂架1降低至不超出第一舱体3的高度或者道路行驶的最大限制高度。
在上述各实施例中，卸下轮胎4、收回防护墙2和降低臂架1高度的步骤顺序可 以互换，可根据操作难易程度决定各步骤执行顺序。
下面以图1至图4的安全检查装置为例，具体说明本公开安全检查装置的结构和转场方法。
如图1所示，安全检查装置包括臂架1、第一舱体3、防护墙2、第二舱体3’和轮胎4。臂架1包括横臂12和两个竖臂13，两个竖臂13之间形成检查通道A。第一舱体3和第二舱体3’连接在臂架1的两侧竖臂13上，且臂架1设置在第一舱体3和第二舱体3’的在检查通道A延伸方向上的前后侧面之间，左右侧的防护墙2分别与第一舱体3和第二舱体3’连接。
同时设置第一舱体3和第二舱体3’，并使臂架1安装于第一舱体2和第二舱体3’上，使安全检查装置的各部分配合关系更加稳定，利于减少转场后辐射检查设备的现场调试工作，也利于辐射检查设备在各种状态的整体稳定性，辐射探测装置的各组成部分布置也更加灵活。
左右侧的防护墙2分别与第一舱体3和第二舱体3’连接。轮胎4可通过支架5安装在第一舱体3和第二舱体3’底部。图1中安全检查装置处于工作状态，臂架1处于升高状态。
如图2所示，支架5设有四个，分别设置在第一舱体3和第二舱体3’各自沿检查通道A延伸方向的两侧，每个支架5对应安装一个轮胎4。防护墙2设有四个，分别设置在第一舱体3和第二舱体3’各自沿检查通道A延伸方向的两侧。设置在第一舱体3沿检查通道A延伸方向的两侧的防护墙2之间具有预设距离，以使射线源发射的射线能够顺利照射到待检物上。设置在第二舱体3’沿检查通道A延伸方向的两侧的防护墙2之间也可具有预设距离，以通过第二舱体3’对这段距离进行防护；或者也可以相互连接成连续的防护墙，以实现更好的防护。图2中的安全检查装置处于工作状态，防护墙2处于未折叠状态。
如图3所示，安全检查装置处于运输状态，将轮胎4从第一舱体3和第二舱体3’上拆卸下来，臂架1降落至不超出第一舱体3和第二舱体3’的高度，使整个安全检查装置的高度与第一舱体3和第二舱体3’的高度大致相等，同时防护墙2朝着检查通道A的中线向内侧折叠。
如图4所示，安全检查装置处于运输状态，折叠后防护墙2位于第一舱体3和第二舱体3’的前后侧面之间，使整个安全检查装置在前后方向上的宽度与第一舱体3和第二舱体3’的宽度大致相等。
在运输前，将轮胎4从第一舱体3和第二舱体3’上拆卸下来；将臂架1降落至第一舱体3和第二舱体3’的高度以下，以使整个安全检查装置的高度与第一舱体3和第二舱体3’的高度大致相等；同时，将四个防护墙2分别朝着检查通道A的中线向内侧折叠，折叠后四个防护墙2均位于第一舱体3和第二舱体3’的前后侧面之间，以使整个安全检查装置的宽度与第一舱体3和第二舱体3’的宽度大致相等。
在臂架1降落和防护墙2折叠后，在臂架1、第一舱体3、防护墙2和第二舱体3’均处于连接的状态下，对安全检查装置进行转场运输。轮胎4可以单独运输，也可以与臂架1、第一舱体3、防护墙2和第二舱体3’的连接体通过同一运输设备一起运输。
到达检查场地后，将安全检查装置从运输设备上卸下来，臂架1、第一舱体3、防护墙2和第二舱体3’仍保持连接状态，现场无需重新安装和重新调试，也不需要临时搭建防护墙并对防护墙进行土建工作，将轮胎4安装到第一舱体3和第二舱体3’上，臂架1升起，防护墙2展开，即可使安全检查装置投入工作状态。
以上对本公开所提供的一种安全检查装置及其转场方法进行了详细介绍。本文中应用了具体的实施例对本公开的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本公开的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开原理的前提下，还可以对本公开进行若干改进和修饰，这些改进和修饰也落入本公开权利要求的保护范围内。
