The invention relates to the technical field of railway tracks or railway track accessories, and provides a fastener looseness detection device, system and method, the fastener looseness detection device comprises a fixed seat, a follower, an electronic chip and a moving part, the fixed seat is fixedly connected with a fastened body; the follower is fixedly connected with the nut of the fastener, and the follower and the nut rotate synchronously; the electronic chip is arranged in the fixed seat; the moving part is slidably arranged in the fixed seat, and the follower rotates to drive the moving part to move from a first position to a second position; when the moving part is located at the first position, the moving part is electrically connected with the electronic chip, and the electronic chip outputs first information to the acquisition device; and when the moving part is located at the second position, the moving part is separated from the electronic chip, and the electronic chip outputs second information to the acquisition device. Whether the nut of the fastener rotates or not is judged by collecting the information output by the electronic chip, 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.
本发明涉及铁路轨道或铁路轨道附件技术领域,提供一种扣件松动检测装置及系统、方法,包括固定座、随动件、电子芯片和移动件,固定座与被紧固体固连;随动件与扣件的螺帽固连,随动件与螺帽同步旋转;电子芯片设在固定座内;移动件滑动设在固定座内,随动件转动能带动移动件由第一位置移动至第二位置;移动件位于第一位置时,移动件与电子芯片电连接,电子芯片向采集装置输出第一信息;移动件位于第二位置时,移动件与电子芯片分离,电子芯片向采集装置输出第二信息。通过采集电子芯片输出的信息来判断扣件螺帽是否转动,以判断扣件是否松动或具有松动趋势,以在铁路扣件的螺帽松动旋转发生时即可给出预警,有效避免扣件实际脱落的风险。
