The invention provides detection equipment for turnout rails, which comprises a frame, a moving mechanism mounted at the bottom of the frame and at least one rail detection unit mounted on the frame, the moving mechanism comprises a plurality of bearing wheels and two distance detection units, and the frame moves on rails through the plurality of bearing wheels. In the moving process, the track can be detected through the track detection unit. As the independent distance detection unit is arranged, the situation that an encoder is installed in a bearing wheel in an existing detection vehicle is avoided, even if the bearing wheel is suspended or jumps due to the surface defect of the track or the structure at the turnout, the distance detection unit can still detect the accurate moving distance; therefore, the detection result of the track detection unit can accurately correspond to the correct track position. Besides, the track detection unit is designed as an independent module and can be disassembled and assembled as a whole, so that disassembly, assembly and maintenance are more convenient and faster, the position change between detection parts in the maintenance process can be effectively avoided, and the detection precision can be improved as well.

    本发明提供一种道岔铁轨用检测设备,包括车架、装在车架底部的移动机构、装在车架上的至少一个轨道检测单元,其中移动机构包括多个承载轮及两个距离检测单元,车架通过多个承载轮在轨道上移动,在移动过程中可通过轨道检测单元对轨道进行检测。由于具有独立的距离检测单元,而不像现有的检测车将编码器安装在承载轮内,因此即使因轨道表面缺陷或道岔处的结构造成承载轮悬空或跳动,距离检测单元仍可测得准确的移动距离,使得轨道检测单元的检测结果能够准确对应到正确的轨道位置。此外,轨道检测单元作为独立模块设计,可作为一个整体进行拆装,拆装维护更为方便快捷,也可有效避免维护过程中检测部件之间的位置变动,同样能够提高检测精度。
