The invention relates to the technical field of railway fastener looseness detection, and provides a fastener looseness detection device and system, the fastener looseness detection device comprises a fixed seat and a movable part, the fixed seat is fixedly arranged on a fastened body, the movable part is connected with a nut of a fastener, the movable part can synchronously rotate along with the nut, and the movable part can move from a first position to a second position, an electromagnetic shielding space is arranged on the fixed seat, an electronic tag is arranged on the movable part, and when the movable part is located at the first position, the electronic tag can be detected by the acquisition device; when the movable part is located at the second position, the electronic tag is located in the electromagnetic shielding space. Whether the nut of the fastener rotates or not is judged by detecting the state of the electronic tag through the acquisition device, so that whether the fastener is loosened or has a loosening trend or not is judged, early warning can be given when the nut of the railway fastener is loosened and rotates, and the risk that the fastener actually falls off is effectively avoided; an existing railway fastener system structure and an installation technology do not need to be changed, and an existing safety structure is not affected.

    本发明涉及铁路扣件松动检测技术领域,提供一种用于检测扣件松动的装置及系统,包括固定座和活动件,固定座固定设置在被紧固体上,活动件与扣件的螺帽连接,活动件能够随螺帽同步旋转,活动件能够由第一位置移动至第二位置,其中,固定座上设置有电磁屏蔽空间,活动件上设置有电子标签,活动件位于第一位置时,电子标签能够被采集装置检测;活动件位于第二位置时,电子标签位于电磁屏蔽空间内。通过采集装置来检测电子标签的状态来判断扣件的螺帽是否转动,以判断扣件是否松动或具有松动的趋势,可以在铁路扣件的螺帽松动旋转发生时给出预警,有效避免扣件实际脱落的风险;无需改变现有铁路扣件系统结构和安装工艺,不影响其现有的安全结构。
