下面详细描述本发明的实施例,所述实施例的示例在附图中示出,其中自始至终 相同的标号表示相同的元件。 下面通过参考附图描述实施例以便解释本发明。
参看图 1至图 4, 根据本发明实施例的移动式车辆检査系统, 通常称为扫描车, 包 括移动装置, 所述移动装置包括底盘架 10和安装在底盘架 10底部的一对前轮 27a和 一对后轮 27b。
在底盘架 10上安装有射线源 23, 射线源 23用于发射诸如 X射线的射线, 以便对 被检查车辆及其上的货物进行扫描和检查。回转台 0可枢转地安装在底盘架 10上, 在 回转台 0上安装了可以随其可枢转的立柱 9。
横探测器梁 7的一端与立柱 9的上端相连且从立柱 9的上端大体上水平延伸, 竖 探测器梁 2的上端与横探测器梁 7的另一端相连, 且竖探测器梁 2从横探测器梁 7的 另一端大体垂直延伸, 从而立柱 9、 横探测器梁 7、 和竖探测器梁 2构成大体倒" U"形 的框架。 横探测器梁 7和竖探测器梁 2分别设置有用于接收从射线源 23发出的 X射 线的探测器阵列,被检査车辆 22从所述倒" U"形框架穿过以便被从射线源 23发出的 X 射线扫描和检查。
根据本发明实施例的移动式车辆检査系统还包括在扫描检査期间驱动移动装置移 动的驱动装置 3。 具体而言, 驱动装置 3仅在扫描检查期间驱动后轮 27b, 可选地, 也 可以驱动前轮 27a,或同时驱动前轮 27a和后轮 27b。而在不检查扫描被检查车辆期间, 即, 当横探测器梁 7和竖探测器梁 2 (倒" U"形框架)縮回底盘架 10上时, 驱动装置 3 不提供驱动力给后轮 27b, 以便车辆检査系统可以在例如动力车头 1 或单独的机动车 的带动下从一个工作地点移动到另一个工作地点。
由于立柱 9随回转台 0可枢转, 从而横探测器梁 7和竖探测器梁 2可以绕立柱 9 在缩回位置 (参见图 1 ) 和伸出位置 (参见图 2和图 3 ) 之间摆动, 其中在缩回位置, 横探测器梁 7和竖探测器梁 2 (倒" U"形框架)位于底盘架 10上面, 而在伸出位置, 横探测器梁 7和竖探测器梁 2位于底盘架 10之外以便被检査车辆能够通过倒" U"形框 架, 并且在伸出位置, 射线源 23发出的 X射线正对横探测器梁 7和竖探测器梁 2的 探测器阵列。
所述底盘架 10可以为普通车辆的底盘架, 优选地, 与底盘架 10—体地连接有动 力车头 1, 用于在非检查期间带动底盘架 10移动, 动力车头 1的动力可以通过动力传 递装置传递到前轮 27a和 /或后轮 27b。 由于普通车辆的底盘架宽度相对窄, 因此, 可 以在普通车辆的底盘架上设置宽度更宽的辅助底盘架, 以便构成具有更大宽度的底盘 架 10, 从而可以将更多的构成扫描车的装置设置在底盘架 10上。
需要说明的是, 动力车头 1和驱动装置 3不同时提供驱动力给底盘架 10。 例如, 在扫描检査期间, 驱动装置 3将动力提供给后轮 27b, 从而驱动底盘架 10移动, 此时 动力车头 1不提供动力给前轮 27a和 /或后轮 27b。 相反, 在非扫描检査期间, 如上所 述, 驱动装置 3不提供驱动力给前轮 27a和 /或后轮 27b, 动力车头 1通过动力传递装 置将动力提供给前轮 27a和 /或后轮 27b, 从而驱动底盘架 10移动,这与普通机动车的 驾驶相同。
优选地, 根据本发明实施例的移动式车辆检査系统包括设置在所述底盘架 10底部 的辅助支撑装置 4, 所述辅助支撑装置 4位于倒 "U"形框架一侧, 用于在检查期间辅助 支撑底盘架 10, 以便保持底盘架的平衡。 所述辅助支撑装置 4包括安装到底盘架 10 上的连接座 26; 滚轮 21 ; 支撑臂 25, 支撑臂 25的一端与连接座 26可转动地铰接, 而另一端通过轴承 (为示出) 与滚轮 21连接; 和第一液压缸 24, 所述第一液压缸 24 的一端与底盘架 10可转动地铰接, 而另一端与支撑臂 25的中间部分可转动铰接, 以 便驱动支撑臂 25摆动, 从而使滚轮 21在检査扫描期间接触地面, 且在非检查扫描期 间和倒 "U"形框架不伸出的情况下离开地面。
进而, 根据本发明实施例的移动式车辆检査系统包括坡台装置 20, 所述坡台装置 用于提升被检查车辆 22距离地面的高度。 例如, 如果被检查车辆 22为小型车辆, 那 么在通过倒" U"形框架时, 射线源 23发出的 X射线无法扫描到被检査车辆 22的下部, 为此, 需要用坡台装置 20提高被检查车辆 22的高度, 如图 3所示。
坡台装置 20包括第一坡台段 20a和第二坡台段 20b, 第一坡台段 20a包括: 中间 水平段 20a-l ;分别可拆卸地连接在中间水平段 20a-l两端的两个过渡段 20a-2, 20a-2; 和分别与两个过渡段 20a-2, 20a-2可拆卸地连接的两个倾斜段 20a-3, 20a-3。 同样, 第二坡台段 20b包括: 中间水平段 20b~l ; 分别可拆卸地连接在中间水平段 20b-l两端 的两个过渡段 20b-2, 20b-2; 和分别与两个过渡段 20b-2, 20b-2可拆卸地连接的两个 倾斜段 20b-3, 20b-3。 进而, 所述坡台装置 20 进一步包括大体长方体状的连接框架 20c, 所述第一和第二坡台段 20a, 20b的中间段 20a-l, 20b-l分别与连接框架 20c的 相对两侧可枢转地铰接, 以便当坡台装置 20 处于拆开和折叠状态时, 拆下的过渡段 20a-2, 20a-2, 20b-2, 20b-2能够放置到所述连接框架 20c里面, 所述第一和第二坡台 段 20a, 20b的中间段 20a-l , 20b-l能够翻转到连接框架 20c的顶面上, 且拆卸下的倾 斜段 20a-3, 20a-3, 20b-3, 20b-3能够分别叠放在中间段 20a-l, 20b-l上, 如图 5所 示。
根据本发明实施例的车辆检查系统进一步包括设置在底盘架 10上的坡台支撑架 13 和与在底盘架 10连接的坡台吊装装置 5, 所述坡台吊装装置 5用于将处于拆开和折叠 状态的坡台装置 20吊装到坡台支撑架 13上或从坡台支撑架 13吊到地面上。 优选地, 所述坡台吊装装置 5包括电动葫芦。
根据本发明实施例的进一步改进中,所述车辆检査系统进一步包括第二液压缸 19, 所述第二液压缸 19的一端固定在底盘架 10上, 另一端与回转台 0可转动连接, 用于 驱动所述回转台 0转动, 从而在縮回位置和伸出位置之间转动由立柱 9,横探测器梁 7 和竖探测器梁 2构成的倒" U"形框架。
根据本发明实施例的车辆检査系统进一步包括设置在底盘架上的发电机舱 11 , 和 设置在发电机舱 11内的发电机 12及发电机控制装置 (未示出), 所述发电机 12用于 给车辆检査系统提供电力。 可选地, 也可以利用外部电源给车辆检査系统提供电力。 更优选地,所述移动式车辆检査系统进一步包括用于冷却射线源 23的射线源水冷机组 16。
如上所述, 在非扫描检查期间, 即, 当横探测器梁 7和竖探测器梁 2 (倒" U"形框 架) 缩回底盘架 10上时, 车辆检査系统的底盘架 10 (移动装置) 可以由与底盘架 10 一体连接的车头 1驱动, 也可以通过单独的机动车 (未示出) 拖动。
另外, 底盘架 10还可以设置车辆检査系统的其他构成部分。 例如, 控制舱 8安装 在底盘架 10的中部, 设备舱 18安装在底盘架 10后部的一侧。控制舱 8内包括扫描控 制模块, 图形获取模块, 运行检査模块和液压泵站 14。 设备舱 18内安装有控制柜 15, 电子柜 17和射线源水冷机组 16。 控制舱 8的顶部安装有空调机组 6, 用于给控制舱 8 和设备舱 18提供制冷和加热。 回转台 0可以设置在设备舱 18的一侧。 所述坡台支撑 架 13和坡台吊装装置 5可以安装在发电机舱 11的顶部。
下面描述根据本发明实施例的移动式车辆检査系统 (扫描车) 的操作。
参看图 1, 扫描车处于非扫描检查状态, 横探测器梁 7和竖探测器梁 2缩回而紧 贴控制舱 8的一侧, 滚轮 21通过第一液压缸 24拉动支撑臂 25而离开地面一定距离, 从而能够保证扫描车在道路上在动力车头 1的驱动下正常行驶。坡台装置 20处于拆开 并折叠状态, 如图 5所示, 并固定在坡台支撑架 13上, 由此不需要其它车辆进行运载 坡台装置 20。
参看图 2和图 3, 根据本发明额扫描车处于扫描检査状态, 横探测器梁 7和竖探测 器梁 2伸出的过程如下: 扫描车在工作场地停稳后, 系统操作人员给扫描车通电, 启 动液压泵站 14, 液压系统致动第一液压缸 24。 第一液压缸 24的活塞杆伸出, 推动支 撑臂 25带动滚轮 21沿图 4中的逆时针方向转动,直到滚轮 21与地面接触为止, 如图 4所示。液压系统致动第二液压缸 19, 第二液压缸 19驱动回转台 0转动, 使横探测器 梁 7和竖探测器梁 2 (倒" U"形框架)伸出底盘架 10之外, 并且与底盘架 10的纵向轴 线大体垂直。
接下来, 操作人员通过坡台吊装装置 5将拆开和折叠状态的坡台装置 20从坡台支 撑架 13上吊到地面上。 然后, 将坡台装置 20组装起来, 如图 2和 3所示。 被检查车 辆 22开上组装的坡台装置 20上, 扫描车的司机下车后离开扫描车。 扫描车在驱动装 置 3的驱动下向前运动, 从射线源 23发出的 X射线穿过并扫描停在坡台装置 20上的 被检査车辆 22, 从而获得被检査车辆 22上的货物的图像。 至于图像的获取和成像控 制与现有技术相同, 在此省略详细的描述。
