The invention belongs to the technical field of railway equipment, and particularly discloses a sensor fixing device for track detection. The sensor fixing device for track detection comprises a pairof bases. Clamping grooves are formed in the base so as to be connected with the side edges, located on the outer sides, of the lower ends of steel rails in a clamped mode. The bases are connected through a telescopic mechanism. An installation base is connected with the end, located on the inner side, of each base and connected with a sleeve through a lifting mechanism, the sleeves are verticallyarranged, and the sleeves are located over the side edges, close to the inner sides, of the lower ends of the steel rails. An adjusting bolt, a first stretching spring and an air bag are arranged inan inner hole of each sleeve in sequence from top to bottom, a groove which holds an acoustic emission sensor is formed in the lower end of each air bag, each air bag is connected with an air cushionthrough a pipe, the air cushions are laid in the clamping grooves and the bases, and the clamping grooves and the bases make contact with the steel rails through the air cushions. According to the sensor fixing device for track detection, the vibration of acoustic emission sensor bodies can be effectively eliminated, the situation that the acoustic emission sensors and the steel rails are kept abutting against each other in real time is guaranteed, a coupling agent is conveniently replaced and smeared, and the accuracy of a detection result is ensured.

    本发明属于铁路设备技术领域,具体公开了一种用于轨道检测的传感器固定装置,包括一对底座,底座均设置有卡槽,以卡接钢轨下端位于外侧的侧边,底座之间通过伸缩机构连接,且底座位于内侧的一端连接有安装座,所述安装座通过升降机构连接有竖直设置的套筒,套筒位于钢轨下端靠向内侧的侧边的正上方,套筒的内孔中从上往下依次设置有调节螺栓、第一伸缩弹簧和气囊,且所述气囊的下端设置有容纳声发射传感器的凹槽,气囊管连接有铺设在所述卡槽和底座的气垫,卡槽和底座通过气垫和钢轨接触。本发明能够有效消除声发射传感器本体震动,保证声发射传感器和钢轨实时保持抵触,且方便更换涂抹耦合剂,确保检测结果的准确性。
