本发明涉及一种铁路轨道结构刚度异常分层检测的移动巡检装置,包括动力移动框架,所述动力移动框架下方设有一组加载轮对和两组走行轮对;动力移动框架上方固设有反力框架,反力框架和加载轮对轮轴之间安装有垂向施压装置;动力移动框架下方设有抱轨轮对,抱轨轮对为垂向施压装置施加的垂向下压力提供反力;数据处理系统接收计轴器、测距传感器、车轮力传感器、结构光传感器获取的数据,开展轨下胶垫失效、扣件异位和轨枕空吊的分层识别。本发明填补了铁路日常工务检测作业中缺乏轨道结构刚度快速巡检和刚度分层识别技术和装备空白,适用于短天窗期内高效率和机动灵活的移动式轨道结构刚度异常分层检测。

    The invention relates to a mobile inspection device for railway track structure rigidity abnormity layering detection, which comprises a power mobile frame, and a group of loading wheel pairs and two groups of walking wheel pairs are arranged below the power mobile frame; a counter-force frame is fixedly arranged above the power moving frame, and a vertical pressure applying device is arranged between the counter-force frame and a wheel shaft of the loading wheel pair; a rail holding wheel pair is arranged below the power moving frame and provides counter force for vertical downward pressure applied by the vertical pressure applying device. And the data processing system receives data acquired by the axle counter, the distance measuring sensor, the wheel force sensor and the structured light sensor, and carries out layered identification of under-rail rubber mat failure, fastener dislocation and sleeper empty hoisting. According to the invention, the blank of lack of rail structure rigidity rapid routing inspection and rigidity layering identification technology and equipment in railway daily public work detection operation is filled up, and the method is suitable for high-efficiency and flexible movable rail structure rigidity abnormity layering detection in a short skylight period.
