The high-speed rail corrugation detection device comprises a detection support, detection wheels and a data processing module, the detection wheels comprise a front detection wheel, a middle detection wheel and a rear detection wheel, the front detection wheel, the middle detection wheel and the rear detection wheel are tightly attached to the rail surface and have the same wheel diameter, and the rear detection wheel and the middle detection wheel re-carve the running path of the front detection wheel. The middle detection wheel and the rear detection wheel are connected through a rigid connecting rod, the middle detection wheel and the front detection wheel are connected through a telescopic connecting rod, angle sensors are arranged on the middle detection wheel and the rear detection wheel, and a telescopic length sensor is arranged on the telescopic connecting rod. The rear detection wheel and the middle detection wheel are provided with speed displacement sensors used for measuring rotation angles of the rear detection wheel and the middle detection wheel. The device is high in detection precision, can continuously measure the long-distance rail-direction profile corrugation based on a contact measurement method without depending on a rack fixed to the ground, is small and exquisite, is convenient to carry, is low in machining and assembling difficulty, and is not liable to deform.

    本发明公开了一种高铁钢轨波磨检测装置及方法,包括检测支架、检测轮和数据处理模块,所述检测轮包括与轨面紧贴的轮径相同的前检测轮、中检测轮和后检测轮,后检测轮、中检测轮复刻前检测轮行驶的路径,中检测轮和后检测轮之间通过刚性连接杆相连,中检测轮和前检测轮通过伸缩连接杆相连,在中检测轮、后检测轮上设有角度传感器,在伸缩连接杆上设有伸缩长度传感器,在后检测轮和中检测轮上设有用于测量后检测轮和中检测轮上旋转角度的速度位移传感器。本发明检测精度高,可在不依靠与地面固定的机架的前提下,基于接触式测量法实现对于长距离轨向廓形波磨的连续测量,装置小巧,携带方便,装置加工及装配难度低,装置不易变形。
