技术领域
本发明涉及安全检测技术领域，尤其涉及一种定点停车装置以及安全检查系统。
背景技术
由于核技术的迅速发展，随之而来的安全问题也日益被重视，目前通用的保障安全的方式是对各种车辆进行扫描检测。现有技术中对车辆应用辐射成像检测技术进行检测的检测系统中主要设置有：检测通道，在检测通道中设置有射线源以及阵列探测器，其中射线源可以为加速器、X光机或同位素等。该检测系统目前主要为固定式和车载式两种。
目前，多采用的是固定式的检测通道，检测时，需要将检测车辆停于检测通道入口的指定位置处。然后待驾驶人员离开驾驶室后，使用拖车固定住检测车辆的前轮，并拖动检测车辆从检测通道的入口运动至检测通道的出口，以通过检测通道内的检测装置对检测车辆进行检测。为了使检测车辆能够准确地停至检测通道的指定位置处，目前主要有两种方式，第一种是在检测通道的底面挖设定位坑，当检测车辆的前轮进入定位坑中后驾驶员则可以停车。但是使用此种方式辅助定位停车时，需要耗费较多人力设置定位坑，并且由于定位坑不可恢复，后续拖车拖动检测车辆行进时，后轮可能受到颠簸而导致全车震动，进而影响辐射成像的效果。第二种方式是采用电机驱动凸轮转动，凸轮与导槽内的挡块悬梁的下表面接触，通 过凸轮转动而推动悬梁带动挡块沿导槽升降，来实现阻止车辆行进。采用此种方式依靠挡块阻止车辆前行，会对车辆造成冲击，进而大大降低驾驶员的乘车舒适性。
因此，亟需一种新的定点停车装置以及安全检查系统。
发明内容
根据本发明的实施例，提供了一种定点停车装置以及安全检查系统，能够实现辅助检测车辆准确地停至检测通道入口的指定位置处，从而提高检测效率，并保证检测车辆辐射成像的清晰度。
根据本发明的一个方面，提供了一种定点停车装置，包括：支承框架、第一转轴、第二转轴、第一翻板、第二翻板和促动机构，其中：第一转轴和第二转轴彼此平行地设置在支承框架上；第一翻板和第二翻板分别通过第一转轴和第二转轴可转动地连接到支承框架上并且彼此相对；并且促动机构分别与第一翻板和第二翻板接合，以驱动第一翻板和第二翻板围绕相应的第一转轴和第二转轴转动，而在第一位置和第二位置之间运动，其中，在第一位置处，第一翻板和第二翻板之间具有预定夹角以在第一翻板和第二翻板之间形成凹陷部；在第二位置处，第一翻板和第二翻板彼此对齐以使第一翻板和第二翻板保持在同一平面。
综上，本发明实施例的定点停车装置以及安全检查系统，通过在支承框架上设置两个彼此平行的第一转轴和第二转轴，并将第一翻板和第二翻板分别通过第一转轴和第二转轴可转动地安装至支承框架上，使安装后的第一翻板和第二翻板彼此相对。并且通过对应第一翻板和第二翻板设置的促动机构分别与第一翻板和第二翻板接合，以驱动第一翻板和第二翻板围绕相应的第一转轴和第二转轴转动，而在第一位置和第二位置之间运动。在第一位置处，第一翻板和第二翻板之间具有预定夹角以在第一翻板和第二翻板之间形成凹陷部。在第二位置处，第一翻板和第二翻板彼此对齐以使第一翻板和第二翻板保持在同一平面。因此，本发明实施例的定点停车装置能够实现辅助检测车辆准确地停至检测通道入口的指定位置处，从而提高检测效率，避免对检测车辆产生冲击，提高驾驶的舒适性，并保证检 测车辆的辐射成像的清晰度。

具体实施方式
下面将详细描述本发明的各个方面的特征和示例性实施例。在下面的详细描述中，提出了许多具体细节，以便提供对本发明的全面理解。但是，对于本领域技术人员来说很明显的是，本发明可以在不需要这些具体细节中的一些细节的情况下实施。下面对实施例的描述仅仅是为了通过示出本发明的示例来提供对本发明的更好的理解。在图中相同的附图标记表示相同或类似的结构，因而将省略它们的详细描述。此外，下文中所描述的特征、结构或特性可以以任何合适的方式结合在一个或更多实施例中。
下述描述中出现的方位词均为图中示出的方向，并不是对本发明的定点停车装置的具体结构进行限定。在本发明的描述中，还需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可视具体情况理解上述术语在本发明中的具体含义。
本发明实施例提供的定点停车装置能够应用于检测系统中，安装于检测通道入口底面的指定停车位置(以下简称指定位置)处，当需要对检测车辆进行检测时，能够通过定点停车装置辅助检测车辆准确地停至检测通道的指定停车位置处，以便可以进一步通过拖车由检测通道内的检测起始位置处拖动检测车辆沿检测通道移动至检测终止位置处，从而完成对检测车辆的扫描检测工作。能够快速地辅助检测车辆进行定点停车，便于对检测车辆的拖动控制，从而提高检测车辆的检测效率。当然，本发明实施例的定点停车装置不限于应用在检测系统中，还可以将定点停车装置应用于其他的需要将车辆停至指定停车位置处的相应环境中，辅助其他的车辆停 止于指定位置，以便于对车辆进行下一步操作。
为了更好地理解本发明，下面结合图1至图5根据本发明实施例的定点停车装置进行详细描述。
请参见图1和图2，其中，图1是根据本发明一个实施例的定点停车装置100处于通过状态的纵向剖面结构示意图；图2是图1中的定点停车装置100处于止动状态的纵向剖面结构示意图。如图1和图2所示，根据本发明的一个实施例的定点停车装置100，包括：支承框架10、第一转轴41、第二转轴42、第一翻板20、第二翻板30和促动机构50。第一转轴41和第二转轴42彼此平行地设置在支承框架10上。第一翻板20和第二翻板30分别通过第一转轴41和第二转轴42可转动地连接到支承框架10上并且彼此相对。并且促动机构50分别与第一翻板20和第二翻板30接合，以驱动第一翻板20和第二翻板30围绕相应的第一转轴41和第二转轴42转动，而在第一位置和第二位置之间运动。在第一位置处，第一翻板20和第二翻板30之间具有预定夹角α以在第一翻板20和第二翻板30之间形成凹陷部30a。在第二位置，第一翻板20和第二翻板30彼此对齐以使第一翻板20和第二翻板30保持在同一平面。
本发明实施例通过在定点停车装置100的支承框架10处可转动地设置两个翻板，并通过两个翻板围绕固定于支承框架10处设置的固定轴转动，使得两个翻板能够相向转动而在彼此之间形成预定夹角α，进而相对于检测通道(图中未示出)的底面形成凹陷部30a(即两个翻板同时处于第一位置处)，或者，通过两个翻板围绕固定于支承框架10的固定轴转动，使得两个翻板彼此对齐，进而与检测通道的底面保持在同一平面(即两个翻板同时处于第二位置处)。
因此，两个翻板通过在第一位置处形成凹陷部30a，在检测车辆经过定点停车装置100处时，检测车辆的前轮会陷入凹陷部30a中，即检测车辆到达指定位置处。当驾驶员意识到检测车辆的前轮陷入凹陷部30a后，即可进行停车操作，将检测车辆停至指定位置处，即两个翻板在第一位置处使定点停车装置100处于止动状态。两个翻板还可以通过在第二位置处保持在同一平面，在拖车通过固定住检测车辆的前轮而拖动检测车辆沿检 测通道内移动时，可以允许检测车辆的后轮平稳通过，即两个翻板在第二位置处使定点停车装置100处于通过状态，从而避免由于两个翻板处于第一位置处时形成凹陷部30a在检测车辆被拖动时对检测车辆的后轮造成颠簸，影响检测车辆辐射成像的清晰度，进而提高安全检测的准确性，并提高检测车辆的检测效率。
上述的指定停车位置处位于检测通道的入口位置处，但是本发明的实施例并不限于此，在其他的实施例中，指定位置还可以不在检测通道的入口处，而是在检测通道中或者在远离检测通道入口的其他位置处，同样可以通过拖车进一步将检测车辆拖动至检测通道内，而在检测通道内移动完成扫描检测过程。在以下实施例的描述过程中，检测通道的宽度方向即为定点停车装置100的各部分的宽度方向(同定点停车装置100的横向)，而检测通道的长度方向即为定点停车装置100的各部分的长度方向(同定点停车装置100的纵向)。
根据本发明的一个实施例，具体地，支承框架10作为定点停车装置100的整体支撑，其整体为门形结构，采用金属材料制成，且具有侧柱11、侧柱12以及支承平台13。为了辅助检测车辆进行定点停车，定点停车装置100被埋设于检测通道底面的指定位置处凹设的容置空间(图中未示出)中，并且埋设后支承平台13的顶面与检测通道的底面平齐。支承平台13对应指定停车位置开设有定位开口，以便将第一翻板20和第二翻板30容设于定位开口处。当然本发明实施例对于支承框架10的具体结构不进行限制，在其他的实施例中，支承框架10还可以架设于其他的支撑侧柱上，而只具有支承平台13。另外，支承框架10的宽度可以设置为与检测通道的宽度相等，即检测车辆的两个前轮共用一个定点停车装置100进行辅助停车，或者还可以对应检测车辆的两个前轮设置两个定点停车装置100，即检测车辆的两个前轮分别通过各自对应的一个定点停车装置100进行辅助停车。此时，可以将支承框架10沿宽度方向分为结构相同的两部分，并将两个结构相同的支承框架10分别对应检测车辆的途径位置，设置在检测通道的指定位置处，即，在检测通道两侧分别对应检测车辆两个前轮的指定停车位置各设置一个定点停车装置100，而通过两个结 构相同的定点停车装置100对检测车辆的两个前轮同时进行辅助定位。
在以下实施例中，仅以支承框架10的宽度与检测通道的宽度相等的定点停车装置100为例对定点停车装置100的结构进行说明，即，在以下的实施例中，检测车辆的两个前轮共用一个定点停车装置100，并且包括一对第一翻板20和第二翻板30，而此时第一翻板20和第二翻板30沿检测通道宽度方向的延伸尺寸可以等于或者大于检测车辆的宽度。
第一转轴41和第二转轴42固定设置于支承框架10的支承平台13处，并且第一转轴41和第二转轴42彼此平行。第一翻板20通过第一转轴41可转动地设置于支承平台13的定位开口处，而第二翻板30通过第二转轴42对应第一翻板20可转动地设置于支承平台13的定位开口处，以使连接后的第一翻板20和第二翻板30能够分别围绕第一转轴41和第二转轴42转动。
第一翻板20包括轴套21和翻板部件22，而第二翻板30与第一翻板20的结构相同，即同样包括轴套31和翻板部件32，其中，翻板部件22和翻板部件32为相对设置的矩形的板状结构，分别与轴套21和轴套31之间固定连接，由轴套21和轴套31作为翻板部件22和翻板部件32的转动支撑。当然，轴套21和翻板部件22以及轴套31和翻板部件32之间还可以采用一体成型的方式设置，并不影响实现通过轴套21和轴套31分别对翻板部件22和翻板部件32旋转支撑的作用。
由于第一转轴41和第二转轴42彼此平行，导致安装后的第一翻板20和第二翻板30同样彼此平行并相对地布置在支承平台13的定位开口处，并使安装后的翻板部件22和翻板部件32彼此相对地形成接合缝20a。在接合缝20a处，翻板部件22和翻板部件32的边缘彼此接合或者预留预定间隙。在第一翻板20和第二翻板30的厚度较厚时，通过预留预定间隙能够允许翻板部件22和翻板部件32之间进行相对的转动。
请一并参见图3，图3是根据本发明实施例的定点停车装置100沿第一转轴41轴向剖切后的局部结构放大示意图。由于第一转轴41和第二转轴42的结构相同，故以第一转轴41与第一翻板20的轴套21之间的连接关系为例进行说明。如图2和图3所示，沿定点停车装置100的横向剖切 后，可以示意性地看出，在本实施例中，由于第一翻板20和第二翻板30在检测通道宽度方向的延伸尺寸等于或者大于检测车辆的宽度，相应地，轴套21和轴套31的宽度则需要对应地设置为等于第一翻板20和第二翻板30的宽度。
示例性地，可以在第一翻板20和第二翻板30各自宽度方向的两侧分别对应地设置两个第一转轴41和两个第二转轴42。在图3中只示意性地示出了第一翻板20与在沿其宽度方向的一端固定设置的第一转轴41的连接，而未示出第一翻板20与在其另一端固定设置的第一转轴41的连接结构。对第一翻板20的其中一端进行转动支撑的第一转轴41的本体固定连接于支承平台13的支撑部处，而沿第一转轴41本体向外延伸设置有连接段411。第一转轴41通过连接段411与第一翻板20的轴套21之间采用轴承60连接，以保证第一翻板20转动的灵活性。当然轴套21与第一转轴41之间还可以采用其他结构滑动或者滚动配合。轴套21另一端可以采用相同的结构与设置于第一翻板20另一端的第一转轴41连接。由此，通过将第一翻板20和第二翻板30分别可转动地相对设置在支承平台13处，从而能够围绕第一转轴41和第二转轴42自由转动。
促动机构50包括驱动单元和执行单元。执行单元分别与第一翻板20和第二翻板30接合。驱动单元驱动执行单元以使第一翻板20和第二翻板30转动。在本实施例中，驱动单元为电机51，而执行单元为凸轮组件52，并且电机51和凸轮组件52分别固定安装于支承框架10上。在本实施例中凸轮组件52包括凸轮转轴521和凸轮522，其中，凸轮522为偏心轮，并且安装后的凸轮转轴521的中心轴线正对于翻板部件22和翻板部件32之间形成的接合缝20a。电机51与凸轮转轴521传动连接，以通过凸轮转轴521带动偏心轮转动。由于第一翻板20和第二翻板30分别可围绕第一转轴41和第二转轴42自由转动，所以第一翻板20的翻板部件22以及第二翻板30的翻板部件32远离与第一转轴41和第二转轴42连接的自由端分别能够垂靠在偏心轮的周缘上，并且，在电机51驱动凸轮转轴521带动偏心轮转动的过程中，翻板部件22和翻板部件32始终能够垂靠于偏心轮的周缘，与偏心轮的周缘滑动接触。因此，通过电机51驱动偏 心轮转动，使偏心轮能够改变对翻板部件22和翻板部件32的推程，从而使第一翻板20和第二翻板30能够在第一位置和第二位置之间运动。当然，在其他的实施例中凸轮522还可以是变径轮。
在本实施例中，当第一翻板20和第二翻板30处于第二位置时，如图1所示，是通过电机51驱动偏心轮转动，使偏心轮的最大推程正对于翻板部件22和翻板部件32，在偏心轮的支撑作用下翻板部件22和翻板部件32保持于同一平面，即第一翻板20和第二翻板30形成的支承平面与支承平台13的顶面在同一平面内。此时，第一翻板20和第二翻板30同时将支承平台13的定位开口封闭(并不是指完全封闭，当第一翻板20和第二翻板30不完全接合而其之间具有预定间隙时，第一翻板20和第二翻板30只是将定位开口大致封闭)。因此，第一翻板20和第二翻板30同时在第二位置时，能够使检测车辆平稳地从支承平台13通过，即定点停车装置100处于通过位置。
当第一翻板20和第二翻板30处于第一位置时，如图2所示，通过电机51驱动偏心轮转动，使偏心轮的最小推程正对于翻板部件22和翻板部件32，此时偏心轮对于翻板部件22和翻板部件32的支撑高度降低，使得翻板部件22和翻板部件32分别围绕第一转轴41和第二转轴42相向旋转。最终在偏心轮的支撑作用下，翻板部件22和翻板部件32共同倾斜形成预设夹角α，因此，第一翻板20和第二翻板30在支承平台13的定位开口处形成凹陷部30a。检测车辆从支承平台13上经过时，当检测车辆的前轮陷入凹陷部30a中后，驾驶员即会得到已到达指定位置的提示，进行停车操作，即定点停车装置100处于止动位置。
当然凹陷部30a的深度可以根据检测现场的需要进行设置，例如可以根据检测车辆车轮的尺寸、车体重量等选择性地设置。并且在第一位置，第一翻板20和第二翻板30之间形成的预设夹角α也可以通过改变偏心轮的推程来调节，以便使定点停车装置100能够适应多种尺寸和重量的检测车辆。
当拖车拖住停止的检测车辆的前轮而带动检测车辆在检测通道内移动时，可再次控制电机51驱动偏心轮转动，使偏心轮将最大推程正对于翻 板部件22和翻板部件32。以使第一翻板20和第二翻板30在偏心轮的支撑作用下分别围绕第一转轴41和第二转轴42旋转，而恢复至第二位置处，保持与支承平台13的顶面处于同一平面，以便于在使用拖车拖住检测车辆的前轮带动检测车辆在检测通道内移动时，检测车辆的后轮能够平稳通过指定停车位置。
由此，当需要使检测车辆在指定位置处停止时，即可控制电机51驱动偏心轮转动，而使第一翻板20和第二翻板30配合形成凹陷部30a，辅助检测车辆进行定点停车。这样能够使检测车辆快速并准确地停至检测通道的指定停车位置处，提高对检测车辆的扫描检测效率。在使用拖车拖住检测车辆的前轮行进时，通过控制电机51驱动偏心轮转动，使第一翻板20和第二翻板30配合保持于同一平面，从而使检测车辆的后轮能够平稳通过。这样，避免需要像现有技术中那样，为了使检测车辆停至指定位置处，而在检测通道的底面处挖设定位坑，而当使用拖车拖动检测车辆移动时，后轮经过定位坑造成整个检测车辆的颠簸震动，进而影响辐射成像的清晰度，导致检测结果不准确的问题，也不会像现有技术的挡块方式那样对检测车辆造成冲击的问题。因此，本发明实施例的定点停车装置100能够在安全检测过程中提高驾驶的舒适性以及安全检测结果的准确性。
当然，在定点停车装置100中，优选沿支承框架10的宽度方向对应两个前轮在两侧各设置一个促动机构50推动翻板部件22以及翻板部件32进行运动，以在保证对第一翻板20和第二翻板30的正常驱动作用下，能够减轻定点停车装置100整体结构的重量，降低操作难度，并保证第一翻板20和第二翻板30运动的平稳性。
在一个可选的实施例中，第一翻板20还包括耐磨块23，同样地，第二翻板30还包括耐磨块33，使得翻板部件22和翻板部件32可以分别通过耐磨块23和耐磨块33与凸轮522的周缘接触，从而能够保护翻板部件22和翻板部件32免受磨损，进而延长定点停车装置100的使用寿命。另外，耐磨块23和耐磨块33沿翻板部件22和翻板部件32宽度方向的设置尺寸由翻板部件22和翻板部件32与凸轮522的接触面积决定。当然，耐磨块23和翻板部件22之间以及耐磨块33和翻板部件32之间可以采用一 体成型的方式设置，也可以采用分体结构设置。
在上述实施例中，第一翻板20和第二翻板30分别为矩形的板状结构，但是本发明的实施例并不限于此。在其他的实施例中，第一翻板20和第二翻板30还可以为在其接合位置处(即接合缝20a处)具有相互补偿形状的板状结构，例如第一翻板20和第二翻板30还可以为具有齿形边缘的板状结构，并且当第一翻板20和第二翻板30处于第二位置时，其齿形边缘能够彼此补偿而接合，以使第一翻板20和第二翻板30处于第二位置时能够通过彼此接合形成一个完整的支承平面，供检测车辆的车轮通过。
图4是根据本发明另一个实施例的定点停车装置200的纵向剖面结构示意图，如图4所示，在本实施例中，与上述实施例中的定点停车装置100不同之处在于，本实施例中的定点停车装置200的促动机构采用液压的方式驱动第一翻板20和第二翻板30在第一位置和第二位置之间运动。具体地，促动机构的执行单元包括第一液压缸71和第二液压缸72，而驱动单元则为分别驱动第一液压缸71和第二液压缸72运动的液压泵。为了与第一液压缸71和第二液压缸72连接，并简化第一翻板20和第二翻板30的结构，翻板部件22和翻板部件32分别对应地设置有第一肋板24和第二肋板34。第一翻板20通过第一肋板24与第一液压缸71连接，而第二翻板30通过第二肋板34与第二液压缸72连接。
第一液压缸71与第二液压缸72的结构相同。第一液压缸71包括缸体711、活塞712、铰接轴713以及铰接轴714，同样地，第二液压缸72包括缸体721、活塞722、铰接轴723以及铰接轴724。以第一液压缸71为例，第一液压缸71的缸体711通过铰接轴713可转动地与支承框架10连接，安装于侧柱12处，而活塞712通过铰接轴714可转动地与第一肋板24连接。因此，通过第一液压缸71的缸体711和活塞712之间相对的伸缩运动即可驱动第一翻板20围绕第一转轴41旋转。第二液压缸72对第二翻板30的驱动原理与第一液压缸71相同。当活塞712和活塞722分别从缸体711和缸体721中逐渐伸出时，第一翻板20和第二翻板30受到推力到达第二位置，可保持在同一平面(如图4所示)，以便于检测车辆平稳通过。当活塞712和活塞722分别向缸体711和缸体721中收回时，第一 翻板20和第二翻板30受到拉力到达第一位置，同时第一液压缸71和第二液压缸72停止动作，使第一翻板20和第二翻板30保持于第一位置，而相对于支承平台13的顶面形成凹陷部(图中未示出)，以使检测车辆到达指定位置后得到提示而停止。另外，定点停车装置200与定点停车装置100具有相同的效果，故不再加以赘述。
图5是根据本发明再一个实施例的定点停车装置300的纵向剖面结构示意图，如图5所示，在本实施例中，与上述实施例中的定点停车装置100不同之处在于，本实施例中的定点停车装置300的促动机构80采用直线电机的方式驱动第一翻板20和第二翻板30在第一位置和第二位置之间运动。具体地，促动机构80的驱动单元包括第一直线电机811和第二直线电机821，而执行单元同样分为两部分，包括对应第一翻板20设置的第一连杆812、第一滑块813、第一导轨814、铰接轴815以及铰接轴816，和对应第二翻板30设置的第二连杆822、第二滑块823、第二导轨824、铰接轴825以及铰接轴826。为了与第一连杆812和第二连杆822连接，并简化第一翻板20和第二翻板30的结构，翻板部件22和翻板部件32分别对应地设置有第一肋板24和第二肋板34。第一翻板20通过第一肋板24与第一连杆812连接，而第二翻板30通过第二肋板34与第二连杆822连接。
由于第一翻板20和第二翻板30对应的执行单元以及驱动单元结构相同，仅以对第一翻板20驱动的执行单元以及驱动单元进行说明。第一直线电机811支撑设置于侧柱12处，第一导轨814以平行于第一直线电机811的方式被支撑。第一滑块813可移动地套设于第一导轨814上，并且第一滑块813一端与第一直线电机811的推杆连接，以在第一直线电机811的驱动作用下在第一导轨814上滑动。第一连杆812的一端与第一滑块813通过铰接轴816可转动地连接，而第一连杆812的另一端与第一翻板20的第一肋板24通过铰接轴815可转动地连接。
因此，通过第一直线电机811与第一滑块813以及第一导轨814配合，即可驱动第一连杆812带动第一翻板20围绕第一转轴41转动，第二直线电机821对第二翻板30的驱动原理与第一直线电机811相同。当第一 直线电机811和第二直线电机821分别推动第一滑块813和第二滑块823沿第一导轨814和第二导轨824朝向靠近彼此的方向运动时，第一连杆812和第二连杆822分别在第一滑块813和第二滑块823的带动作用下运动并保持于竖直状态。通过第一连杆812和第二连杆822保持于竖直状态能够分别对第一翻板20和第二翻板30施加推顶力，第一翻板20和第二翻板30受到推力到达第二位置，并可保持在同一平面(如图5所示)，以便于检测车辆平稳通过。而当第一直线电机811和第二直线电机821分别拉动第一滑块813和第二滑块823沿第一导轨814和第二导轨824朝向远离彼此的方向运动时，第一连杆812和第二连杆822分别在第一滑块813和第二滑块823的带动作用下运动并保持于倾斜状态，从而第一连杆812和第二连杆822分别拉动第一翻板20和第二翻板30运动并保持在第一位置。第一翻板20和第二翻板30到达第一位置之后，第一直线电机811和第二直线电机821停止动作，使第一翻板20和第二翻板30保持于第一位置，从而相对于支承平台13的顶面形成凹陷部(图中未示出)，以使检测车辆到达指定位置后得到提示而停止。定点停车装置300与定点停车装置100具有相同的效果，故不再加以赘述。
根据本发明的一个实施例，还提供了一种安全检查系统，包括上述任一实施例的定点停车装置，故具有与上述的定点停车装置相同的优点，故不再加以赘述。
根据本发明的一个实施例，还提供了一种采用X射线检查的系统，其包括上述任一实施例中的定点停车装置。不同之处在于，采用X射线检查的系统中的射线源发射装置为X射线发生器，并且采用X射线检查的系统包括上述的定点停车装置。
综上，本发明实施例的定点停车装置通过在支承框架上设置两个彼此平行的第一转轴41和第二转轴42，并将第一翻板20和第二翻板30分别通过第一转轴41和第二转轴42可转动地安装至支承框架10上，使安装后的第一翻板20和第二翻板30彼此相对。并且通过对应第一翻板20和第二翻板30设置的促动机构50、80分别与第一翻板20和第二翻板30接合，以驱动第一翻板20和第二翻板30围绕相应的第一转轴41和第二转轴42 转动，而在第一位置和第二位置之间运动。在第一位置处，第一翻板和第二翻板之间具有预定夹角以在第一翻板20和第二翻板30之间形成凹陷部。在第二位置处，第一翻板20和第二翻板30彼此对齐以使第一翻板20和第二翻板30保持在同一平面。因此，本发明实施例的定点停车装置能够实现辅助检测车辆准确地停至检测通道入口的指定位置处，从而提高检测效率，避免对检测车辆产生冲击，并保证检测车辆的辐射成像的清晰度。
本发明可以以其他的具体形式实现，而不脱离其精神和本质特征。因此，当前的实施例在所有方面都被看作是示例性的而非限定性的，本发明的范围由所附权利要求而非上述描述定义，并且，落入权利要求的含义和等同物的范围内的全部改变从而都被包括在本发明的范围之中。并且，在不同实施例中出现的不同技术特征可以进行组合，以取得有益效果。本领域技术人员在研究附图、说明书及权利要求书的基础上，应能理解并实现所揭示的实施例的其他变化的实施例。
