下面将参照本发明的实施例来进行详细说明, 其中附图中说明了本发明的具体 实施示例,其中相似的引用数字表示相似的部件。下述的实施例通过参照附图来说明。
同时, 在下面的实施例中, 主要通过将所述用于车辆检査的拖车系统应用到车 辆辐射成像检查中的一种情况进行了详细的说明, 但是, 普通技术人员可以理解, 在 不背离本发明的精神和实质的情况下可以将本发明应用到其它的车辆检测中。
下面参照图 1进行说明,图 1是根据本发明的用于车辆检査的拖车系统的俯视图, 所述系统包括车体及地面辅助装置。 所述拖车用于承载将被检测的车辆, 以用于各种 检测的目的, 所述地面辅助装置用于防止被检测车辆横跨在所述拖车上, 以克服现有 技术中所存在的技术问题。
所述车体主要包括车架 1、 翻板机构 2、 定位窝台 3和轮组单元 7 (图 1中未示 出) 等, 翻板机构 2、 轮组单元 7的具体结构将在下面进行详细的说明。 所述翻板机 构在本实施例中以翻板 2的形式来进行实施, 但是普通技术人员可以理解, 可以将所 述翻板 2替换为诸如刹板、 可转动定位板、 可转动横杆等。
所述地面辅助装置主要包括下坡台 5、 辅助支撑件 6 (如图 2中所示) 等, 所述 辅助支撑件 6的具体结构将在下面进行详细的说明。 撞块 4安置在下坡台 5朝向拖车 的侧面上。
所述的下坡台 5固定在出口位置, 即, 所述下坡台 5以一定距离安置在拖车的朝 向出口位置的一侧, 当然所述距离可以根据实际的需要进行适当的调节。 由于下坡台 有一定的长度, 因此避免了被检车横跨在拖车上而使底部受到刮蹭情况的发生。
车架 1 的两侧相对中间部较高, 由此形成凹形结构, 其中间部较低的部分满足 - 不刮蹭被检车底盘的高度要求。 同时, 车架 1用于在其上表面上支撑被检测车辆。
下面将结合图 2— 3对本发明的用于车辆检査的拖车系统的轮组单元 7、 辅助支 撑件 6的具体结构及其作用进行进一步的详细说明。
图 2示出了根据本发明的用于车辆检査的拖车系统的端面视图; 图 3示出了根 据本发明的用于车辆检查的拖车系统的拖车的轮组单元 7结构的示意图。
从图 2中可见, 所述轮组单元 7安装在车架 1的下面, 在本实施例中, 车架安 装有四列轮组单元 7, 并安置在车架 1的两侧。 但是, 普通技术人员可以理解, 根据 情况的需要, 本发明的拖车系统可以多于四列的轮组单元 7。 同时, 所述辅助支撑件 6安装在检测通道出口位置, 并位于拖车在出口停靠位置的正下方。
如图 3所示, 所述的轮组单元 7包括轴承 8、 车轮 9、 支撑架 10、 轴 11及相关 的结构件。 所述车轮 9具有中心孔, 用于让轴 11从其中贯穿, 所述车轮 9配合在结 构件内。 所述轴承 8使得所述轴 11 可进行旋转运动。 所述结构件用于配合到车架 1 上。 所述支撑架 10用于支撑所述车轮 9、 轴 11和轴承 8。 所述轴 11贯穿所述车轮 9 的中心孔定位。 轮组单元 7可独立装配, 并且所述轮组单元 7整体地与车架 1进行安 装。 若干单元通过车架 1的机械加工平面统一定位。 这种单元独立、 定位统一的结构 降低了车架 1的高度, 拆装维修方便。 '
从图 2中进一步可以看出, 所述辅助支撑件 6与拖车底部不接触, 但是所述辅 助支撑件 6与所述拖车的底部留有很小的间隙。 在对被检车 (图中未示出) 扫描结束 后, 拖车拖动被检车停止在辅助支撑件 6的正上方。 当被检车后轴通过拖车时, 由于 通常后轴重量较大, 车架桡度变形增大, 使得拖车底部与辅助支撑件 6接触, 这时辅 助支撑件可以减少车架的变形, 提高拖车的重载通过能力。 需要指出的是, 尽管图 2 中示意地显示了 2个辅助支撑件 6, 但是, 可以注意到辅助支撑件 6只是用于支撑所 述拖车底部, 但是对于辅助支撑件 6的数目和形状并没有具体的要求和限定, 例如其 可以是长方体、 梯状、 扁锥状、 板状等, 数目可以是 2个或者更多个, 这要根据实际 的需要来进行进一步地限定。 同时进一步地, 辅助支撑件 6的支撑高度可调对于本发 明而言是有利的。
下面将参照图 4对本发明的翻板机构 2进行详细说明。 图 4示出了根据本发明 的用于车辆检查的拖车系统的拖车的翻板机构的示意图。
所述的翻板机构 2包括翻板 12、 链条 13、 导杆 14、 调整衬套 15、 弹簧 16、 撞 轴 17、 铰轴 18等。 所述翻板 12用于调整翻板 12抬起的高度与角度, 用于顶紧将被 检测的被检车的前轮。 调整衬套 15用于调整所述翻板 12顶紧停放在拖车上的被检车 辆的前轮的高度和角度。 普通技术人员可以理解, 作为翻板的高度和角度调节用的翻 板制动位置调节装置, 即, 所述调整衬套 15可以很容易用其它能够对翻板 12的角度 和高度进行调节的装置来进行替换, 例如, 靠近翻板 12设置的角度致动机构, 或者 可以是具有预定转动角度的枢转连接件, 上述只是出于说明的目的列出了调整衬套 15, 这不能理解作为本发明的一种限制。 调节衬套 15套装在导杆 14上, 其一端与所 述弹簧 16相抵, 以通过调节所述弹簧 16的拉紧程度来调节所述翻板 12的制动高度 和角度。
所述翻板 12通过铰轴 18与车体 1连接,但是所述连接方式不限于所述铰轴 18, 也可以通过其它的支撑方式来实现所述可转动连接。 所述链条 13与所述翻板 12相连 接, 链条 13连接到所述翻板的连接方式不受到限制, 可以是诸如销连接、 滑动连接、 滚动连接等。
在没有外力作用时, 弹簧 16受压, 导杆 14受拉力作用拉紧链条 13, 翻板 12 抬起。 需要指出的是, 导杆 14只是联动翻板 12的一种结构, 本发明对此并没有特别 限制, 任何能够实现翻板 12在被检车通过时下落的连接件都可以替换所述导杆 14。
当被检车上载时,被捡车的前轮开上拖车,车轮克服弹黉力将翻板 12压至零位, 车轮到达车架 1的定位窝台 3后, 翻板 12在弹簧 16作用下抬起。 当拖车到达下载位 置时, 撞轴 17受到地面撞块 4的作用进一步压紧弹簧 16, 链条 13放松, 翻板 12基 本处于自由状态, 当被检车前轮离开定位窝台 3后, 翻板 12 自然落下, 避免磕碰被 检车底盘及.附件。 当被检车驶离时, 没有外力作用在所述导杆 14上, 弹簧 16试图恢 复弹性变形, 而导杆 14受拉力作用拉紧链条 13 , 翻板 12抬起, 即, 当拖车离开出口 位置往入口方向运动时, 翻板 12在弹簧 16的弹簧力的作用下自动翻起。
在本发明的具体实施例中, 为了尽可能详细地描述本发明的结构、 作用和效果, 将所述辅助支撑件 6安装在检测通道出口侧、 即拖车停靠位置的地面上, 优选地, 辅 助支撑件 6的上工作表面与车架 1下表面的间隙可以通过进一步的精确计算设计。 在 被检车进行诸如扫描的检测结束之后,拖车拖动被检车停止在辅助支撑件 6的正上方。 当被检车后轴通过拖车时, 由于通常后轴重量较大, 车架 1产生较大的挠度变形使车 架 1的底部与辅助支撑件 6接触而得到支撑, 将后轴的重量通过辅助支撑件 6传到地 面, 从而, 达到了减少车架 1的变形、 提高拖车的承载能力的目的。
下面将参照本发明的上述用于车辆检査的拖车系统的具体结构, 并结合附图来 对其具体操作进行详细说明。
通常, 拖车在上载端锚定, 此时翻板 12张开。 然后, 被检车行驶到拖车上并定 位在定位窝台 3上, 整个系统准备就绪。 然后拖车的驱动系统开始工作, 翻板 12顶 紧被检车前轮, 防止被检车移动, 在此状态之下, 拖车带动被检车通过诸如扫描通道 的检测装置或者设备。 在完成了预定的诸如扫描的检测之后, 拖车行驶到下载位置, 此时辅助支撑件 6位于拖车下方, 下坡台 5上的撞块 4顶住拖车上翻板机构 2的撞轴 17, 使弹簧 16进一步受压, 翻板 12的拉力解除处于自由状态。 此时, 司机可以上车 将被检车幵出诸如检测通道的检测装置或者设备。 当被检车后轴通过拖车时, 辅助支 撑件 6可以防止车架产生大的挠度变形, 确保重载车通过, 同时前车轮离开时翻板 12 自然下落。 当拖车离开出口锚定位置时, 翻板 12在弹簧 16的作用下重新自动张开, 然后拖动小车返回上载位置, 准备进入下一次检测。
在上述的对本发明的具体实施例进行了描述, 可以发现, 翻板转动驱动机构通 过链条 13、 导杆 14、 弹簧 16、 撞轴 17和撞块 4来实施。 但是普通技术人员可以显而 易见地得出, 上逑结构的目的只是让翻板机构, 即翻板 12 '发生联动的具体实施方式 的一种。 普通技术人员可以很容易将上述结构用其它可以实施所述翻板机构的联动装 置和致动装置来进行实施。例如,所述联动机构可以是液压致动回路、气压致动回路, 或者旋转电动机。 所述致动装置可以是撞轴和撞块的组合, 或者是接¾开关, 或者任 何能够感知拖车到达下载位的信号的任何装置, 所述装置将此信号发送给联动装置, 并进一步地改变翻板机构的状态。
综上, 显然本发明的用于车辆检査的拖车系统可以应用于对车辆进行各种检测、 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, 所述辐射成像检测系统通常包括加速器、 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, 在本发明中, 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 下将本发明的车辆检查用的拖车系统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, 这也落入本发明的保护范围。
尽管对本发明的优选实施例进行了说明, 但是普通技术人员可以理解, 在不背离 本发明的精神和实质的情况下, 可以对本发明进行修改, 其范围由权利要求书及其等 同限定。
