The invention relates to a method and device for detecting the locked rail temperature of a continuously welded rail track and a detection trolley. The method for detecting the locked rail temperature of the continuously welded rail track comprises the steps that transverse excitation force within a certain frequency range is applied to a to-be-detected steel rail through an excitation module; acquiring a resonant frequency generated by the steel rail to be measured under the action of the transverse exciting force; and determining the locking rail temperature according to the resonant frequency. The method can rapidly and continuously detect the locking rail temperature of each mileage of the to-be-detected seamless track, does not damage the structure of the to-be-detected steel rail, does not need to dismount a fastener system in a certain length range, does not affect the normal operation of a train, is not affected by offline foundations and track types, is wide in application range, is not affected by human factors during detection, and is high in detection accuracy. And the detection result is more accurate.

    本公开涉及一种无缝线路锁定轨温的检测方法、装置及检测小车,无缝线路锁定轨温的检测方法包括:通过激振模块向待测钢轨施加一定频率范围的横向激振力;获取所述待测钢轨在横向激振力作用下产生的共振频率;根据所述共振频率确定锁定轨温。本公开能够快速、连续检测待测无缝线路各个里程处的锁定轨温,同时不会破坏待测钢轨结构,也无需拆除一定长度范围的扣件系统,进而不会影响列车的正常运营,不受线下基础和轨道类型影响,应用范围广泛,在检测时不受人为因素影响,检测结果更加准确。
