本公开的用于有缝轨道200的车辆100可以应用于对被检车辆进行各种检测、计量、测量的系统中，特别是应用到目前在海关、民航、铁路系统中广泛使用的辐射成像检测系统1000，所述辐射成像检测系统1000通常包括加速器、探测器、图像获取装置、扫描装置及运行检查分系统。由于所述辐射成像检测系统1000在现有技术中已经广泛的进行了说明，此处为了简洁起见，不再对其详细的结构和功能进行详细的描述。
另外，在本公开中，明显地，普通技术人员可以在不付出任何创造性劳动的情况下将本公开的用于有缝轨道200的车辆100用于其他用途诸如货车称重、货物输送等的情况，而不仅仅是出于检测的目的，这也落入本公开的保护范围。
相关技术中，用于有缝轨道200的车辆100在有缝轨道200的长度方向F1上只有一个车轮，使得车辆100在行驶至轨道缝隙201处时会出现颠簸，或者车辆100车轮容易卡在轨道缝隙201内，因此对行车造成很大的不便。
下面参考图1-图5描述根据本公开实施例的用于有缝轨道200的车辆100和辐射成像检测系统1000。
如图5所示，根据本公开实施例的辐射成像检测系统1000，包括辐射成像检测装置100a和如上所述的用于有缝轨道200的车辆100，车辆100在有缝轨道200上行驶时适于拖动被检车辆接受辐射成像检测装置100a的安全检查。
如图1-图2所示，根据本公开实施例的用于有缝轨道200的车辆100，有缝轨道200在其长度方向F1上具有至少一个轨道缝隙201，轨道缝隙201在长度方向F1上的尺寸为L，车辆100包括机架1和偶数个车轮组2。机架1包括偶数个安装部11，偶数个安装部11对称分布在机架1的两侧，且沿机架1的长度方向间隔开，其中，有缝轨道200的长度方向F1与机架1的长度方向相同；偶数个车轮组2一一对应地安装于安装部11，每个车轮组2包括第一车轮21和第二车轮22，第一车轮21和第二车轮22沿机架1的长度方向间隔排布，第一车轮21的中心线和第二车轮22的中心线之间的距离为G，其中，G大于L。
在一些具体的示例中，如图2所示，偶数个车轮组2可以为4个。4个车轮组2对称分布在机架1的两侧，每侧机架1的前后各布置一个车轮组2，由此使得车辆100的结构稳定可靠。
根据本公开实施例的用于有缝轨道200的车辆100，通过在有缝轨道200的长度方向F1上排布两个车轮，且两个车轮的中心线之间的距离G大于轨道缝隙201的宽L，可以使得第一车轮21行驶至轨道缝隙201内时，第二车轮22位于轨道实体202上；第二车轮22行驶至轨道缝隙201内时，第一车轮21已经越过轨道缝隙201，由此，车辆100在有缝轨道200上行驶时，每个车轮组2始终有一个车轮位于轨道实体202上，使得每组车轮组2时刻有轨道实体202支撑，从而使得车辆100在行驶至轨道缝隙201处时可以平稳行车，不会出现颠簸或者卡死现象。
根据本公开的一些实施例，如图2所示，用于有缝轨道200的车辆100还可以包括多个驱动件3，多个驱动件3与多个车轮组2一一对应设置，每个驱动件3与一个车轮组2连接，以驱动车轮组2中的第一车轮21和第二车轮22转动。由此，每个车轮组2均可以由一个驱动件3驱动，驱动件3可以为车轮组2提供动力，从而车辆100可以实现行使功能。
在本公开的一些实施例中，如图2所示，每个驱动件3包括第一驱动电机31和第二驱动电机32。其中，第一驱动电机31与第一车轮21连接，以驱动第一车轮21转动；第二驱动电机32与第二车轮22连接，以驱动第二车轮22转动。由此，第一车轮21和第二车轮22均可以有电机驱动，使得每个车轮组2的动力更大，从而增加车辆100行驶的动力。
另外，当第一车轮21行驶至轨道缝隙201内或者第二车轮22行驶至轨道缝隙201时，第一车轮21和第二车轮22均有电机驱动可以便于第一车轮21或者第二车轮22从轨道缝隙201内驶出。
根据本公开的一些实施例，如图2-图4所示，每个驱动件3可以包括驱动电机和皮带33。其中，驱动电机与第一车轮21或第二车轮22连接；皮带33套设在第一车轮21和第二车轮22上，其中，驱动电机用于驱动第一车轮21和第二车轮22中的一个转动，皮带33用于带动第一车轮21和第二车轮22中的另一个转动。
可以理解的是，驱动电机可以与第一车轮21连接，皮带33套设在第一车轮21和第二车轮22上，驱动电机驱动第一车轮21转动，第一车轮21转动带动皮带33转动， 皮带33转动带动第二车轮22转动；驱动电机也可以与第二车轮22连接，皮带33套设在第一车轮21和第二车轮22上，驱动电机驱动第二车轮22转动，第二车轮22转动带动皮带33转动，皮带33转动带动第一车轮21转动。由此，通过一个驱动电机即可实现驱动车轮组2转动，从而可以节约成本和资源。
在本公开的一些实施例中，如图3所示，每个驱动件3还可以包括张紧轮34，张紧轮34设于皮带33外侧，且张紧轮34位于第一车轮21和第二车轮22之间，张紧轮34用于压紧皮带33。由此，通过张紧轮34使得皮带33与第一车轮21和第二车轮22的配合更稳定、可靠，从而便于实现驱动电机驱动第一车轮21和第二车轮22其中一个转动时，皮带33带动另一个转动。同时还可以节省布置空间，减小车辆100体积。
在本公开的另一些实施例中，如图4所示，每个驱动件3还可以包括张紧轮34，张紧轮34设于皮带33内侧，且张紧轮34位于第一车轮21和第二车轮22之间，张紧轮34用于拉紧皮带33。由此，通过张紧轮34使得皮带33与第一车轮21和第二车轮22的配合更稳定、可靠，从而便于实现驱动电机驱动第一车轮21和第二车轮22其中一个转动时，皮带33带动另一个转动。
根据本公开的一些实施例，如图3-图4所示，机架1上开设有长条形固定孔12，张紧轮34可移动地设于长条形固定孔12内，其中，当张紧轮34压紧或拉紧皮带33时，张紧轮34固定在长条形固定孔12内。由此，通过长条形固定孔12可以调整张紧轮34的位置，进而更好地调节皮带33的松紧，使得皮带33与第一车轮21和第二车轮22的配合进一步稳定、可靠。调节好皮带33的松紧后，长条形固定孔12还可以便于张紧轮34的固定。
进一步地，张紧轮34可以通过固定件4固定在长条形固定孔12内。例如固定件4可以为螺纹件、销钉和销柱等，但是并不限于此。
当然，张紧轮34还可以通过卡扣件5固定在长条形固定孔内。
