The invention discloses a whole-line detection device for the radius of a small-curvature rail. The whole-line detection device comprises a first driven wheel and a second driven wheel which are arranged on two sides of the waist of the rail, and a driving wheel and a balance wheel which are arranged on the top of the rail, encoders are mounted on the first driven wheel and the second driven wheel, the first driven wheel and the second driven wheel are in shaft connection with an extension shaft, and a limiting disc is transversely arranged on the extension shaft; a balance plate is fixedly connected to the extension shaft, clamping plates are fixedly installed on the balance plate, the clamping plates are oppositely arranged, the four corners of the clamping plates are connected through four bolts and four nuts, and the clamping plates are parallel to one another; the driving wheel and the balance wheel are respectively connected with a U-shaped frame, a limiting plate is mounted at the top end of each U-shaped frame, an adjusting groove is formed in each limiting plate, the extension shaft penetrates through the adjusting groove, the limiting disc is pressed above the limiting plates, and the diameter of the limiting disc is larger than the width of the adjusting groove; and the encoder is connected with a single-chip microcomputer which is connected with a display screen. The device advances along the rail, can perform whole-line detection on the curvature radius of the rail, and provides data support for screening dangerous points of the rail.

    本发明公开了一种小曲率铁轨半径的全线检测装置,包括铁轨腰部两侧的第一从动轮和第二从动轮,铁轨顶部的驱动轮和平衡轮;第一从动轮和第二从动轮上安装编码器,第一从动轮和第二从动轮轴接有延长轴,延长轴上横向设置限位盘;延长轴上固接有平衡板,平衡板上固定安装夹持板,夹持板相对设置并在四角通过4个螺栓和4个螺母连接,夹持板相互平行;驱动轮和平衡轮各自连接一个U形架,U形架顶端安装限位板,限位板上开设调节槽,延长轴从调节槽中穿过,限位盘压在限位板上方,限位盘的直径大于调节槽的宽度;编码器连接有单片机,单片机连接显示屏。本发明沿铁轨行进,能够对铁轨的曲率半径进行全线检测,为筛查铁轨危险点提供数据支撑。
