具体实施方式
本公开的实施例提供一种安检设备，包括：射线源，发射射线；和探测器，用以探测射线源发出的射线，其中，射线源和探测器限定安检通道。射线源可以是X射线源，也可以是其他射线源。图1示出一种透射型的安检设备，射线源和与射线源相对地布置地探测器限定安检通道；然而，安检设备可以是例如背散射型的安检设备，此时射线源和探测器可以位于同一侧，被检查对象可以从安检通道上通过而被检查。
在一个实施例中，安检设备可以包括屏蔽壳体1-3，屏蔽壳体1-3由能够屏蔽射线的材料构成，包括入口和出口，安检通道位于屏蔽壳体1-3的入口和出口之间。在屏蔽壳体1-3的入口可以设置铅门帘。
在一个实施例中，安检设备可以包括入口附加胶带机1-6和出口附加胶带机1-5，如图1所示，入口附加胶带机1-6具有倾斜的坡度，以便将物品送至安检通道中的传送装置，在完成检查之后，物品通过出口附加胶带机1-5被送至地面。在一个实施例中，传送装置的一端伸出屏蔽壳体1-3的入口，另一端伸出屏蔽壳体1-3的出口。入口附加胶带机1-6布置在传送装置的伸出屏蔽壳体1-3的入口的一端，出口附加胶带机1-5布置在传送装置的伸出屏蔽壳体1-3的出口的另一端。
在本实施例中，安检设备包括传送装置1-2，布置在安检通道上以便传送被检查物品。被检查物品包括行李箱包等物品，在机场还会有运送行李的推车1-1。在本实施例中，传送装置1-2包括用以推动车轮3-2的牵引装置2-2。这是有利的，因为传送装置1-2包括推动例如推车1-1的车轮3-2的牵引装置2-2，因而可以推动带有车轮3-2的推车1-1 通过安检通道，从而不用将行李从推车1-1上搬下来，然后再检查完之后再装到推车1-1上，使得安检更加方便和快捷。
传送装置1-2还包括传送带2-1，配置用以支撑被检物品和传送被支撑的被检物品。这是有利的，传送装置1-2因而能够传送行李通过安检通道；换句话说，本实施例的传送装置1-2的配置方式既能够通过传送带2-1传送行李箱包等物品通过安检通道，还能够通过牵引装置2-2传送具有车轮3-2的易移动的推车1-1，例如载物小车等，尤其是机场这种场合使用的行李车，从而允许例如机场或车站的携带任何物品和/或推车1-1的乘客方便地通过安检设备，并且提高安检的速度和效率。
在一个实施例中，传送装置1-2还包括导向槽2-5，设置在传送装置1-2中。在本实施例中，传送带2-1分为两个部分；牵引装置2-2布置在导向槽2-5内。在本实施例中，牵引装置2-2布置在传送装置1-2的导向槽2-5内，因而牵引装置2-2不会影响传送带2-1传送行李箱包等物品。然而，在其他实施例中，传送装置1-2可以不包括导向槽2-5，牵引装置2-2设置在传送带2-1的一侧或两侧；或者，在一个实施例中，牵引装置2-2设置在传送带2-1上部，虽然传送带2-1上设置有牵引装置2-2，然而传送带2-1还有剩余的平坦部分，因而传送带2-1仍然满足传送行李箱包等物品的需求。
在一个实施例中，传送装置1-2包括一对转筒2-4、2-6，所述传送带2-1的两个部分通过一对转筒2-4、2-6形成回路，以在回路中循环移动。一对转筒2-4、2-6同时旋转，从而可以带动围绕一对转筒2-4、2-6的传送带2-1沿回路运动。一般情况下，在传送带2-1和一对转筒2-4、2-6的这种布置中，一对转筒2-4、2-6会适度地张紧传送带2-1，以便带动传送带2-1运动。
在一个实施例中，牵引装置2-2包括柔性传动机构和设置在柔性传动机构上的至少一个牵引横档3-3，所述柔性传动结构形成回路循环运行以便将柔性传动机构上的至少一个牵引横档3-3从安检通道的一端传送至另一端(例如屏蔽壳体1-3的入口传送至屏蔽壳体1-3的出口)。牵引横档3-3配置用于抵靠车轮3-2以便推动车轮3-2移动。当带有车轮3-2的推车1-1被乘客推到如图1和2所示的安检设备左侧的入口，推车1-1的车轮3-2经过乘客推推车1-1的动作而跨过一个牵引横档3-3，或者，牵引横档3-3随着柔性传动机构沿柔性传动机构形成的回路运动，当车轮3-2进入后，牵引横档3-3随着柔性传动机构运动而从车轮3-2后面抵靠车轮3-2，向车轮3-2施加横向力，推动车轮3-2向前移动。牵引横档3-3与车轮3-2接触的点在车轮3-2的圆周的上部，即牵引横档3-3与车轮3-2接触的点高度大于车轮3-2的半径，或者说牵引横档3-3与车轮3-2接触的点 高度在车轮3-2的轴的水平以上，这样牵引横档3-3在车轮3-2的上半圆周上推车轮3-2，推车1-1因而被牵引横档3-3推动通过安检通道。在本公开的一个实施例中，提供一种牵引横档3-3，包括牵引轴4-3和套接在牵引轴4-3上的牵引套筒4-2，牵引轴4-3连接至柔性带状材料，所述牵引套筒4-2能够围绕牵引轴4-3转动。牵引套筒4-2可以通过牵引轴承4-1支撑在牵引轴4-3上。这样的配置，允许车轮3-2从牵引横档3-3的牵引套筒4-2跨过，牵引套筒4-2的转动使得车轮3-2容易地跨过牵引轴4-3，在推动推车1-1移动过程中，牵引套筒4-2可以转动因而允许车轮3-2转动；并且，在车轮3-2离开牵引横档3-3时，牵引横档3-3的牵引套筒4-2的转动减小与车轮3-2之间的摩擦。
此处，推车1-1的其他部分可以放置在传送带2-1上。然而，在其他实施例中，图3的牵引装置2-2可以单独布置在安检通道内，这样其他带轮的小车(此处机场专用的推车1-1由于后轮带有刹车，因而需要牵引装置2-2牵引后轮)的其他车轮3-2可以在地面上，小车可以被牵引装置2-2推动移动通过安检通道；此时安检通道中可以布置传送带2-1或可以不布置传送带2-1。安检通道可以仅布置牵引装置2-2，从而提供例如单独的检查推车1-1的安检通道，这样分类检查的方式也是有利的。
在一个实施例中，牵引装置2-2的柔性传动机构包括柔性带状材料3-1和两个牵引转轴3-0，柔性带状材料3-1围绕两个远离的牵引转轴3-0形成回路，通过两个牵引转轴3-0的转动使得柔性带状材料3-1在回路中循环运行。本实施例的牵引转轴3-0可以是与上面所述的转筒2-4、2-6不同的；然而，在一个实施例中，牵引转轴3-0可以省略，柔性带状材料3-1围绕所述一对转筒2-4、2-6，转筒2-4、2-6张紧柔性带状材料3-1并带动柔性带状材料3-1运动。这样的配置方式可以简化整个设备的复杂度，降低成本。在一个实施例中，柔性带状材料3-1可以是链条；柔性带状材料3-1可以是皮带。牵引横档3-3可以通过例如焊接、紧固件或其他连接装置固定在柔性带状材料3-1上；牵引横档3-3可以是多个，在柔性带状材料3-1运动时，多个牵引横档3-3分布在柔性带状材料3-1构成的回路上。
在一个实施例中，柔性传动机构包括两个柔性带状材料3-1，至少一个牵引横档3-3的两端分别固接至两个柔性带状材料3-1以便设置在两个柔性带状材料3-1之间并沿两个柔性带状材料3-1的运行方向的横向方向布置。推车1-1的车轮3-2可以置于两个柔性带状材料3-1和牵引横档3-3之间的空间中，牵引横档3-3随着两个柔性带状材料3-1沿柔性带状材料3-1形成的回路运动，从而推动车轮3-2向前。这种配置方式可以稳定地推动车轮3-2向前移动。两个柔性带状材料3-1上设置多个牵引横档3-3是有利的，这样 推车1-1的车轮3-2可以更快地被柔性带状材料3-1上设置的一个牵引横档3-3推动，而不用等待一个牵引横档3-3运行一周而等待太长时间。
在一个实施例中，牵引横档3-3的一端固接至柔性带状材料3-1并且沿柔性带状材料3-1的运行方向的横向方向布置。在本实施例中，柔性带状材料3-1可以是一个，牵引横档3-3的一端固接至柔性带状材料3-1并沿横向延伸(未示出)，例如牵引横档3-3的牵引轴4-3的一端连接至柔性带状材料3-1，牵引横档3-3的牵引套筒4-2沿柔性带状材料3-1的横向伸出，用于接触车轮3-2并推动车轮3-2移动。一个牵引横档3-3能够推动车轮3-2向前移动，从而允许简化牵引装置2-2和整个安检设备的结构。
在一个实施例中，牵引装置2-2包括柔性传动机构和设置在柔性传动机构上的至少一个夹紧机构5-1，所述柔性传动结构形成回路循环运行以便将柔性传动机构上的至少一个夹紧机构5-1从安检通道的一端转移至另一端。在本实施例中，至少一个夹紧机构5-1配置用于夹紧车轮3-2以便带动车轮3-2将车轮3-2从安检通道的一端转移至另一端。在本实施例中，在柔性传动机构的柔性带状材料3-1上设置至少一个夹紧机构5-1，所述柔性带状材料3-1沿回路循环运行以便将设置在柔性带状材料3-1上的至少一个夹紧机构5-1从安检通道的一端传送至另一端，例如从屏蔽壳体1-3的入口传送至出口。在柔性传动机构的柔性带状材料3-1上设置多个夹紧机构5-1，这样推车1-1的车轮3-2可以更快地被柔性带状材料3-1上设置的一个夹紧机构5-1夹住而推动，而不用等待太多时间。
在一个实施例中，如图6所示，至少一个夹紧机构5-1包括槽型壳体6-0，和布置在槽型壳体6-0两个侧壁6-01(例如顶部)上的夹块6-1，所述夹块6-1布置成在所述车轮3-2置于两个夹块6-1之间时抵靠所述车轮3-2的两侧并朝向车轮3-2施加力。两个夹块6-1具有弹性，在所述车轮3-2被置于两个夹块之间时两个夹块6-1被车轮3-2挤压而发生弹性变形。具体地，夹块6-1的一端连接至槽型壳体6-0的一个侧壁6-01，夹块6-1从与槽型壳体6-0的一个侧壁6-01连接的一端向槽型壳体6-0的两个侧壁6-01之间延伸，例如可以沿椭圆形或圆形的一部分延伸，也可以沿其他形状的一部分延伸，使得两个夹块6-1的另一端相互靠近，两个夹块6-1之间的最小间距可以是两个夹块6-1的另一端，也可以是两个夹块6-1的其他部分，例如两个夹块具有弧形的形状时，夹块6-1的末端朝向侧壁收回，夹块6-1的中间部分相互之间的距离最短。当车轮3-2由于重力压入两个夹块6-1之间，两个夹块6-1被车轮3-2挤压而发生弹性变形，或者说，车轮3-2被两个夹块6-1夹住。在本实施例中，夹块6-1具有弧形的顶部，车轮3-2的轴可以搁置在两 个夹块6-1的弧形的顶部(两个夹块6-1的最靠近部位)，车轮3-2的轴的下侧半圆被夹块6-1的最靠近部分夹住。两个夹块6-1的不与槽型壳体6-0的一个侧壁6-01连接的自由端部可以分别朝向相互远离的方向，从而使得夹块6-1的自由端部不会妨碍车轮3-2的轴的下侧半圆离开夹块6-1。
在一个实施例中，如图7所示，两个夹块6-1通过各自对应的扭簧6-2朝向槽型壳体6-0的两个侧壁6-01中间支撑，并且在所述车轮3-2被置于两个夹块6-1之间时两个夹块6-1被车轮3-2挤压而朝向槽型壳体6-0的两个侧壁6-01压缩各自对应的扭簧6-2。
在另一个实施例中，如图7所示，两个夹块6-1分别通过各自的带杆转轴6-3可枢转地连接在槽型壳体6-0的对应的侧壁6-01上，其中带杆转轴6-3包括从带杆转轴6-3沿轴线延伸方向的横向、向上伸出的杆6-30。两个夹块6-1具有相互面对的面，车轮3-2的两侧分别与两个夹块6-1的相互面对的面中的一个抵接，并且由于两个夹块6-1的相互面对的面之间的间距小于车轮3-2的厚度，因而车轮3-2会挤压两个夹块6-1。在本实施例中，两个夹块6-1可以不具有弹性，它们可以围绕带杆转轴6-3枢转，并且通过扭簧6-2的弹力张紧。在本实施例中，槽型壳体6-0的两个侧壁6-01的顶部还设置附加的托架6-4，托架6-4可以用于将槽型壳体6-0安装至柔性传动机构的柔性带状材料。在本实施例中，托架6-4还可以设置成允许车轮3-2的轴搁置在两个附加的托架6-4上，车轮3-2的轴的下侧半圆被两个夹块6-1夹住。在本实施例中，如图5所示，牵引装置2-2还可以包括设置在牵引装置2-2的靠近安检通道出口的一端的一对挡片5-2，使得所述至少一个夹紧机构5-1朝向所述一对挡片5-2移动时，一对挡片5-2分别接触对应的带杆转轴6-3的杆6-30并导向所述杆6-30使其转动，从而带杆转轴6-3被转动，夹块6-1松开所述车轮3-2。所示的一对挡片5-2之间的距离在传送装置1-2的传送方向上变化，具体的，所示的一对挡片5-2从远离安检通道出口朝向靠近安检通道出口延伸并且所示的一对挡片5-2之间的间距逐渐减小。
在本公开的一个实施例中，安检设备布置在机场中，乘客携带行李箱包等物品，部分乘客使用推车1-1将多个箱包放置在推车1-1上，当乘客经过安检设备时，乘客可以将手提的物品放置在入口附加胶带机1-6上，物品被入口附加胶带机1-6传送至传送装置1-2的传送带2-1上，被传送带2-1经由安检通道传送至屏蔽壳体1-3的出口，最后从出口附加胶带机1-5传送离开安检设备。部分乘客可以将承载着箱包的推车1-1直接推到入口附加胶带机1-6上，并继续推，也可以不用乘客推动推车1-1，推车1-1的一个车轮3-2跨过牵引横档3-3，车轮3-2的大部分落在牵引横档3-3的靠近屏蔽壳体1-3的出 口一侧，推车1-1的底部可以搁置在牵引横档3-3上，车轮3-2可以离开地面或传送带2-1，推车1-1的其他车轮3-2可以搁置在传送带2-1上或地面上，这样推车1-1被牵引装置2-2牵引通过安检通道。在另一实施例中，推车1-1的车轮3-2可以被推入夹紧机构5-1的槽型壳体6-0，也可以是推车1-1的车轮3-2可以被推入两个柔性带状材料3-1之间或一个柔性带状材料3-1的一侧，随着柔性带状材料3-1的循环移动，柔性带状材料3-1上的多个夹紧机构5-1的一个靠近车轮3-2，车轮3-2被夹入槽型壳体6-0中的两个夹块6-1之间，车轮3-2的轴搁置在附加的车轮3-2托架6-4上，夹紧机构5-1推动车轮移动，从而推动推车1-1移动，通过安检通道，完成安检。
