The invention discloses a railway wheel tread out-of-roundness rapid measuring instrument, and relates to the technical field of railway vehicle detection. The two ends of the arc box are open, the arc rods are arranged in the arc box in an array mode in the front-back direction, the micrometer gauges are arranged on the two sides of a wheel body respectively, the extension lines of probes intersect with the circle center of the wheel body, and the micrometer gauges are fixedly connected to a mounting block in a sleeving mode; the arc box is arranged on the outer side of the wheel body, the arc box, the wheel body and the arc rods are concentrically arranged, and each set of arc rods is composed of two symmetrical arc rods; fixing blocks are arranged at the ends, closest to one side of the wheel body, of the two symmetrical arc rods in the direction of the wheel body in an extending mode, and the two fixing blocks are fixedly connected with the two mounting blocks in a one-to-one correspondence mode. According to the invention, the out-of-roundness of the wheel can be fully and conveniently detected, the detection operation of the out-of-roundness is simple, the detection data of the out-of-roundness of the wheel is sufficient and accurate, and the overall practicability is good.

    本发明公开了一种铁道车轮踏面不圆度快速测量仪,涉及铁道车辆检测技术领域。本发明包括两端呈开口的圆弧盒、沿前后方向阵列设置在圆弧盒内部的多组圆弧杆和分别设置在车轮本体两侧且探头的延长线与车轮本体圆心相交的测微计,测微计固定套接在安装块上;圆弧盒设置在车轮本体的外侧,且圆弧盒、车轮本体和圆弧杆呈同心设置,每一组圆弧杆由两个呈对称的圆弧杆构成;最靠近车轮本体一侧的两个呈对称的圆弧杆的一端上均向车轮本体方向延伸设置有固定块,且两个固定块与两个安装块一一对应固定连接。本发明可以对车轮不圆度进行充分而便捷的检测,不圆度的检测操作简单,同时对车轮不圆度检测的数据充分且准确,整体实用性好。
