具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
图1是本发明提出的检查***的一个实施方式的主视图；
如图1所示，根据本发明的实施例的车辆检查***包括：分段式车辆拖动***100、检查通道200和射线检查***300。
图2是本发明实施例的检查***的俯视图，如图2所示，分段式车辆拖动***100包括：沿拖动车辆的方向E依次排列的第一拖动装置111和第二拖动装置112，在拖动车辆的方向E上，所述第一拖动装置111设置在所述第二拖动装置112的上游并且所述第一拖动装置111和所述第二拖动装置112之间设有间隔部分113，使得在拖动车辆的方向E上所述第一拖动装置111和所 述第二拖动装置112间隔开预定距离。第一拖动装置111和第二拖动装置112设置在检查通道200中。所述射线检查***300，设置于所述第一拖动装置和第二拖动装置之间，使所述射线检查***300的射线的至少一部分的路径穿过所述第一拖动装置111和所述第二拖动装置112之间的间隔部分113。
在本发明的一些实施例中，射线检查***300包括：设置在所述第一拖动装置111和所述第二拖动装置112之间的间隔部分113的上方和下方中的一方的射线源，以及至少部分地设置在所述第一拖动装置111和所述第二拖动装置112之间的间隔部分113的上方和下方中的另一方的用于接收射线源发出并穿过被检查车辆的射线的探测器。射线源可以是X射线源，或其它合适的射线源。在所述检查通道200两侧设置防护墙，在所述检查通道200范围内设置扫描装置框架，所述射线源设置于扫描装置框架的顶部，以对通过检查通道200的车辆进行扫描，探测器设置在与射线源相对应的地面下。
图3是本发明实施例的检查***的侧视图，图4、图5是本发明实施例的车辆检查***的分段式车辆拖动***的俯视图，如图3、图4、图5所示，所述第一拖动装置111包括第一支撑板1111，第一细长牵引件1112，以及与所述第一细长牵引件1112连接的第一推动件1113，该第一推动件1113围绕第一支撑板1111运行用于推动车轮沿第一支撑板1111运动，使车辆行进，本实施例中，所述第一细长牵引件1112采用链条结构，称为第一链条。所述第二拖动装置112包括第二支撑板1121，第二细长牵引件1122，以及与所述第二细长牵引件1122连接的第二推动件1123，该第二推动件1123围绕第二支撑板1121运行用于推动车轮沿第二支撑板1121运动，使车辆行进，本实施例中，所述第二细长牵引件1122采用链条结构，称为第二链条。
虽然以链条作为细长牵引件进行了描述，但是本发明的细长 牵引件可以是任何合适的细长牵引件，例如板链、皮带等。
图6是本发明实施例的车辆检查***的控制示意图，车辆检查***包括分段式车辆拖动***，其中分段式车辆拖动***包括两个拖动装置，如图6所示，所述第一拖动装置111设有第一传感器1114，该第一传感器1114设置在车辆前轮离开位置的下降沿，用于车辆前轮离开第一拖动装置111时发出信号，所述第二拖动装置112上设有第二传感器1124，用于在车辆前轮行进到刚好与第二拖动装置112接触的位置时发出信号；
控制器控制所述第一推动件1113以第一速度推动车辆后轮，当收到第一传感器1114发出的信号时控制第二细长牵引件1122即第二链条移动，使第二推动件1123从开始移动到所述第二推动件1123与车辆前轮接触的时间间隔与第一传感器1114发出信号到第二传感器1124发出信号的时间间隔相等，并且第二推动件1123以所述第一速度与车辆前轮接触并推动车辆前轮，以保持车辆的匀速运行状态。
本发明通过在前后分段式拖动装置上合理布置第一传感器1114和第二传感器1124的位置以及第二拖动装置的第二细长牵引件的初始位置，进而确定第一传感器1114、第二传感器1124以及第二推动件1123之间的位置关系，并通过控制器前后精确控制两段拖动装置上的推动件的运动，使车辆可以匀速通过两段扫描装置，不需要改变射线检查***中X射线发生装置的出束频率，也不用考虑车轮直径调节加减速时间，减少了出束和探测***控制的复杂性，提高***的检测效率。另外，设置于第一拖动装置和第二拖动装置之间的射线检查***，其射线源发出的射线可以经过第一拖动装置和第二拖动装置之间的空隙，并被探测器接收，这就避免了射线照射到拖动装置上引起的拖动装置及推动件对扫描图像的影响，从而使得扫描图像仅含有被检车辆的透射信息。
进一步地，在第一推动件1112与车辆后轮分离前，第二推 动件1123与车辆前轮接触。
进一步地，所述第二细长牵引件的初始位置根据预设的所述第二推动件与所述第二传感器之间的距离进行设置。
在本发明实施例中，在第一拖动装置111的B点布置第一传感器1114检测车辆前轮离开的下降沿，车辆的从左向右由第一拖动装置111运动到第一拖动装置112，左边的第一拖动装置111的第一推动件1113推动车辆的后轮，使小车以速度V向右运动。当车辆前轮到达设置于位置B处的传感器时，右边的第二拖动装置112上的第一推动件1123停靠在初始位置C点。在第二拖动装置112的A点布置第二传感器，A点为车辆前轮行进到刚好与第二拖动装置112接触的位置。
其中，所述第二细长牵引件1122的初始位置根据预设的所述第二推动件1123与所述第二传感器1124之间的距离进行设置，使得直线距离BA与弧线CA相等，因此，在车辆前轮离开B时，启动第二拖动装置112，并以同样的速度V靠近车辆前轮(不考虑加速时间)，第二拖动装置的第二推动件1123正好能靠住车辆前轮以速度V匀速推动车辆前进，以保持车辆的运行状态。由于B点的第一传感器1114检测车辆前轮离开时的下降沿，第二拖动装置的第二推动件1123启动时机不受被扫描车辆车轮直径变化的影响。其中，B点布置的第一传感器1114位置需要与弧长CA对应、高度需要定在推进器与车轮接触点的高度。
本发明的另一实施例中，在第一拖动装置111的B点布置第一传感器1114检测车辆前轮离开的下降沿，第二细长牵引件1122的初始位置根据预设的所述第二推动件1123与所述第二传感器1124之间的距离进行设置，使得直线距离BA大于弧线CA，即BA＞CA，则在车辆前轮离开B时，延迟一个时间段再启动第二细长牵引件1122的第二推动件1123，使其加速追赶前轮，然后减速靠轮，控制第二推动件1123紧贴到车辆前轮，并以速度V1匀 速前进，以保持车辆的匀速运行状态，使所延迟的时间段和第二推动件1123从开始移动到第二推动件1123与车辆前轮接触的时间间隔之和与第一传感器1114发出信号到第二传感器1124发出信号的时间间隔相等。类似地，同样适用于直线距离BA等于或小于弧线CA。其中第二推动件1123的速度-时间曲线可参照图7。
其中，第二细长牵引件1122加速运动，然后再减速运动到第一速度。
其中，所述加速运动可以是匀加速运动。
其中，所述减速运动可以是匀减速运动。
其中，所述第一传感器1114和/或所述第二传感器1124可以是光电传感器、接近开关和压力传感器等，本发明对此不做限定。本实施例方案中，车辆运动速度保持V1，不需要改变射线检查***中X射线发生装置的出束频率，也不用考虑车轮直径调节加减速时间，减少了出束和探测***控制的复杂性。
本发明实施例中推动件可以是推辊或其他具有相同功能的结构。推动件的形状可以有圆柱形、楔形、梯形、三角形，推动件的材料可以是不锈钢、高分子材料等，本发明对此不做限定。
本发明提供的分段式车辆拖动***和车辆检查***，在前后分段式拖动装置上设置的传感器以及拖动***输出转矩，精确控制第二拖动装置，跟上前轮，使车辆整体匀速通过两段扫描装置，避免前后轮因速度不同而被拖拽，以及因不同车轮直径不同，导致追赶车轮时加减速时间需要根据车轮直径反复调整的问题，有效地提高了检查效率。
以上实施方式仅用于说明本发明，而并非对本发明的限制，有关技术领域的普通技术人员，在不脱离本发明的精神和范围的情况下，还可以做出各种变化和变型，因此所有等同的技术方案也属于本发明的范畴，本发明的专利保护范围应由权利要求限定。
