发明人知晓的安全检查装置能够通过伸缩装置的伸缩运动改变横臂的长度，从而依据待检测物品的尺寸改变检测通道的尺寸，以提升本公开所提供的安全检查装置对不同的货物、组合式货物、车载式货物或车辆的检测效率。
经研究发现，由于货物种类多样，尤其是对于组合式货物、车载式货物或车辆的检测而言，由于待检测物品的形状、尺寸难以统一，需要在检测区域设置适用于不同形状、尺寸待检物品的检测装置，并将待检物品按照形状、尺寸不同而分类，以分别通行与自身形状、尺寸相对应的检测装置，导致检测效率低下。此外，对于部分组合式货物、车载式货物和车辆而言，其宽度方向的尺寸远小于长度方向的尺寸。对于这类货物，以其宽度方向通过检测装置时，对检测装置的可通行性要求较低。然而，在检测区域中，货物码放、车辆停放往往比较紧密，调整组合式货物、车载式货物和车辆的角度，并以其宽度方向通过检测装置的操作难度往往较高，同样导致检测效率底 下。
有鉴于此，本公开实施例提供一种安全检查装置，能够提升对不同形状、尺寸、摆放方式的物品的检测效率。
图1为本公开一些实施例所提供的安全检查装置的正视角度结构示意图。如图1所示，本公开提供的一种安全检查装置，包括：门式框架，包括位于顶部的横臂1，和位于横臂两侧并与横臂连接的两个竖臂2(包括第一竖臂2(a)和第二竖臂2(b))，门式框架通过横臂和两个竖臂所围成的区域构成检测通道；以及基于辐射成像的物品检测组件3，至少部分地设置于门式框架，用于对通过门式框架的物品进行检测；其中，横臂1包括伸缩装置11，能够通过自身的伸缩运动改变横臂1的长度。
本公开实施例通过伸缩装置的伸缩运动改变横臂的长度，从而依据待检测物品的尺寸改变检测通道的尺寸，以提升本公开实施例所提供的安全检查装置对不同的货物、组合式货物、车载式货物或车辆的检测效率。
基于辐射成像的物品检测组件3可以利用射线观察物体内部。物品检测组件3可以在不破坏物体的情况下获得物体内部的结构和密度等信息，目前已经广泛应用于车站、码头和机场的安检。
对于待检测物品为货物、组合式货物、车载式货物或车辆等情况，以组合式货物为例，本公开所提供的安全检查装置能够通过自身的伸缩运动改变横臂1的长度，进而对组合式货物所具有的不同尺寸和形状进行适应性调整，使探测通道能够容许组合式货物通过。
而对于本领域技术人员而言，使待检测货物通过探测通道可以通过多种现有方式，包括但不限于传送带、运输小车等，在此不再详述。相应地，通过使安全检查装置具有一定的移动能力，例如装配以车轮、或配置以滑轮滑轨，也能在待检测物品不移动的情况下，使安全检查装置的探测通道经过待检测物品。
在一些实施例中，伸缩装置包括至少一级的伸缩油缸。
伸缩油缸可以连接至控制液压油路中，进而使操作人员可以方便地通过控制液压油路调整伸缩油缸的伸缩运动；伸缩油缸也可以被配置为手动输入压力，以降低伸缩装置的成本，并获得较为简单的控制方式。
伸缩油缸可以为一级，也可以为多级，当伸缩油缸为多级时，可以使伸缩油缸具有更大范围的伸缩运动。并且对于多级伸缩油缸而言，通过对每一级伸缩油缸进行控制，可以使伸缩油缸的伸缩运动更加迅捷，操作响应速度更快。
图2为本公开一些实施例所提供的安全检查装置的正视角度未伸长状态示意图。如图2所示，在一些实施例中，横臂包括：伸缩横臂13，两端分别连接至两个竖臂，能够伸长或缩短以改变横臂的长度；和固定横臂12，一端连接至两个竖臂中的至少一个，用于支撑伸缩横臂。
固定横臂能够对伸缩横臂起到支撑的作用，进而提高横臂的整体强度与刚度。尤其对于当横臂在伸缩装置的作用下具有较大的长度时，固定横臂能够有效降低横臂的挠度，使得设置在横臂上的元器件受到较小的影响，提高对待检测物品的检测效果。
此外，设置的固定横臂还可以作为伸缩横臂做伸缩运动的导轨，使横臂在伸缩横臂伸长或缩短的过程中更加平稳，使应用辐射成像原理、对振动较为敏感的物品检测组件较少地受到横臂伸缩运动的影响，进而使至少部分地设置在门式框架上的的物品检测组件减少故障率，提高使用寿命。图3为本公开一些实施例所提供的安全检查装置的正视角度伸长状态示意图。图2至图3即示出了本公开借助伸缩横臂与固定横臂实现伸长或缩短横臂长度的过程。
图4为本公开一些实施例所提供的安全检查装置的正视角度结构示意图。如图4所示，在一些实施例中，安全检查装置包括：升降装置21，能够通过自身的升降运动使两个竖臂做上升或下降运动。升降装置可以使用伸缩油缸，也可以使用其他可以提升或降低竖臂的装置，例如千斤顶或其他机构。
并且如图4所示，升降装置位于竖臂2上物品检测组件3的上方，能够使物品检测组件3在升降装置21做升降运动时，继续由竖臂与地面接触进行支撑，从而较少受到升降运动的影响。然而本领域技术人员应当理解，升降装置还可以位于物品检测组件3的下方，或者其他能够改变竖臂长度的位置。
通过升降装置对竖臂上升或下降的调节，横臂能够具有不同的高度位置。对于具有较高高度的待检测物品而言，通过提高横臂的高度位置，能够使得本公开所提供的物品检测组件继续得以适用；而对于具有较低高度的待检测物品而言，也可以通过较低横臂的高度位置，使横臂贴近于待检测物品的上侧，提高设置在横臂上的物品检测组件的探测精度。
在一些实施例中，安全检查装置包括：轮式行走装置23，分别设置在两个竖臂(包括第一竖臂2(a)和第二竖臂2(b))的下端，能够通过自身的行走运动使安全检查装置相对于地面行走和转向。
轮式行走装置23可以被配置为具有自主行走能力的轮体机械，也可以被配置为 与预设的滑轨向配套的滑轮机械组件。轮式行走装置23可以使安全检查装置具有移动能力，从而方便安全检查装置的转场、位置调整以及对静止待检测物品的检测。
轮式行走装置23作为门式框架与地面相接触的部件，应当在检测状态下具有较强的稳定性，因而可以配套以固定支腿或其他部件，以提供安全检查装置在静止状态下时的稳定性。
图5为本公开一些实施例所提供的安全检查装置的正视角度结构示意图。如图5所示，在一些实施例中，安全检查装置包括：射线舱体，设置于两个竖臂之一(即第一竖臂2(a)或第二竖臂2(b))，射线舱体包括射线源，能够发射探测射线对通过门式框架的物品进行扫描；探测器，设置于门式框架，能够探测探测射线在物品上的透射信号或散射信号，以便进行扫描成像；和防护墙，设置于两个竖臂中的另一个(即对应的第二竖臂2(b)或第一竖臂2(a))。
探测器设置的位置包括与射线源所在的竖臂相同、相对的竖臂，以及设置于横臂三种位置。对应的，当探测器设置于与射线源所在的竖臂相对的竖臂和/或设置于横臂时，探测器探测的信号以投射信号为主；而当探测器设置于与射线源所在的竖臂相同的竖臂时，探测器探测的信号以散射信号为主。投射信号与散射信号能够反映待检测物品的不同信息，因而具有不同的成像原理与检测侧重点，可以依据待检测物品的种类或安全检查装置的工作场景有选择的设置。
在一些实施例中，横臂包括：伸缩横臂，两端分别连接至两个竖臂，伸缩横臂能够伸长或缩短以改变横臂的长度；和固定横臂，一端连接至两个竖臂中的至少一个，用于支撑伸缩竖臂；其中，至少部分探测器设置在伸缩横臂。
至少部分设置在伸缩横臂的探测器能够保证在横臂伸长的过程中，探测器均能比较完整地探测到检测通道上方区域的探测信号，以使对待探测物品的扫描成像更加完整准确。
在一些实施例中，安全检查装置包括：第一探测臂，与固定横臂固定连接；和第二探测臂，与固定横臂、第一探测臂或伸缩横臂可转动地连接；其中，探测器分别安装在第一探测臂和第二探测臂上。
在横臂伸缩的过程中，由于检测通道的可通过面积增大，使得原有的探测器不再能够充分覆盖扫描区域，因此通过在固定横臂上设置第一探测臂，并设置与伸缩横臂、第一探测臂或伸缩横臂上转动连接的第二探测臂，用于在通道截面改变的情况下，扩大探测器的探测区域。
具体而言，当第二探测臂铰接于固定横臂未固定于竖臂的一端，第二探测臂可选择向固定横臂的一侧旋转，也可以选择向活动横臂的一侧旋转。当安全检查装置处于较小的检测通道状态时，伸缩横臂相对长度较短，此时设置于固定横臂上的第二探测臂可依据被探测物品的大小，选择转向固定横臂，并与第一探测器并排设置，此时可有选择地开启第一探测器或第二探测器两者之一。而当安全检查装置处于较大的检测通道状态时，第二探测臂可以转向伸缩横臂伸长的方向，并收合于伸缩横臂，与第一探测臂共线并排设置，从而使伸长的伸缩横臂部分具有探测器，能够有效扩大在较大检测通道状态下的横臂的探测范围。
而当第二探测臂铰接于固定横臂或伸缩横臂固定于竖臂的一端时，第二探测臂可选择向固定横臂或活动横臂旋转，此时第二探测臂与第一探测臂均被设置于横臂上；第二探测臂也可以选择向两个竖臂之一旋转，此时第一探测臂继续位于横臂，而第二探测臂则位于两个竖臂之一。上述两种设置方式，即第二探测臂位于横臂或两个竖臂之一，将带来两种检测通道内的探测范围，因此可以依据待检测货物的状态灵活选取。
在一些实施例中，安全检查装置包括：升降装置，能够通过自身的升降运动使两个竖臂做上升或下降运动；和轮式行走装置，分别设置在两个竖臂的下端，能够通过自身的行走运动使安全检查装置相对于地面行走和转向。
在一些实施例中，安全检查装置包括：控制器，用于对升降装置的升降运动、伸缩装置的伸缩运动和轮式行走装置的行走运动进行控制。
控制器可以通过液压控制系统构建，也可以通过电气控制系统构建，具体依据控制器控制对象的运作原理。通过控制器，操作人员能够比较省力且便捷地对安全检查装置进行多种运动控制，从而使安全检查装置能够适应于各种应用场景。
在一些实施例中，控制器被配置为：控制伸缩装置执行横臂的伸缩运动和/或升降装置执行门式框架的升降运动，以改变检测通道的尺寸。
如前文，检测通道的尺寸可以根据待检测物品的尺寸而灵活确定，并且可以使检测通道的尺寸仅略大于待检测物品的尺寸，以获得更佳的检测效果。相应地，由于伸缩装置或升降装置均可被配置为具有多级结构，对待检测物品的检测可以相应的具有一定的顺序。例如，先对只需进行一级伸缩或升降运动的待检测物品进行检测，再依次对需要进行两次、三次及更多次伸缩或升降运动的待检测物品进行轮流检测，以使每轮检测过程中，控制器都只需对同一级伸缩装置或升降装置进行控制。
为了实现对本公开所提供的安全检查装置的远程操纵，在一些实施例中，安全检 查装置包括：遥控器和遥控指令传递组件，遥控指令传递组件设置在门式框架上，并与控制器电连接，遥控器能够与遥控指令传递组件远程通信，以便操作人员远程控制升降装置、伸缩装置和轮式行走装置。
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：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；而不脱离本公开技术方案的精神，其均应涵盖在本公开请求保护的技术方案范围当中。
