The invention discloses a portable rail car wheel tread surveying instrument, and relates to the field of tread surveying instruments, the portable rail car wheel tread surveying instrument comprises a group of detection frames, the inner side ends of the group of detection frames are provided with concave-convex detection mechanisms, a plurality of mutually rotatably connected connecting rods are connected between the detection frames, and the top surfaces of the connecting rods are provided with gradienters; the concave-convex detection mechanism comprises sliding rods, an inner roller and an elastic distance detection mechanism, and the inner side end of each detection frame is slidably connected with a plurality of sets of sliding rods. According to the invention, the plurality of inner rollers are slidably connected to the inner side of the detection frame, and the elastic distance detection mechanism is installed between the inner rollers and the detection frame, during use, the inner rollers cooperate with the detection frame to clamp the track, and when the detection mechanism moves, the elastic distance detection mechanism detects the movement of the inner rollers, so that the wear of the side surface of the track can be known. The gradienter on the connecting rod is used for detecting whether the heights of the top surfaces of the two rails are the same or horizontal so as to determine the abrasion of the top surfaces of the rails.

    本发明公开了一种便携式轨道车车轮踏面测绘仪,涉及踏面测绘仪领域,包括一组检测架,一组所述检测架的内侧端皆设置有凹凸检测机构,所述检测架之间连接有多根相互转动连接的连接杆,且连接杆的顶面安装有水平仪,所述凹凸检测机构包括滑杆、内滚轮与弹性距离检测机构,每个所述检测架内侧端皆滑动连接有多组滑杆。本发明通过在检测架的内侧滑动连接多个内滚轮,在内滚轮与检测架之间安装弹性距离检测机构,使用时,通过内滚轮配合检测架夹住轨道,在检测机构移动时,通过弹性距离检测机构检测内滚轮的移动,即可得知轨道侧面的磨损,通过连接杆上的水平仪检测两根铁轨顶面的高度是否相同,是否水平,以确定铁轨顶面的磨损。
