The invention provides a measuring wheel device and a track inspection trolley. The measuring wheel device comprises a fixed seat, a wheel shaft assembly and a measuring wheel, wherein the wheel shaft assembly is arranged in the fixed seat, and the measuring wheel is rotatably arranged at the lower end of the fixed seat through the wheel shaft assembly; the measuring wheel comprises a measuring part, a guiding part and an avoiding part, the measuring part is circumferentially arranged on the outer wall of the measuring wheel, the avoiding part is arranged on the side, facing the fixed seat, of the measuring part, and the guiding part is arranged on the other side of the measuring part. The avoiding part is arranged on the measuring wheel to avoid the fat edge of the track, so that the running stability of the track detection trolley on the track is improved, further, the guiding part is arranged on the other side of the measuring part, the track detection trolley is guided to enter or exit from the working state through the guiding part, the mounting efficiency of the track inspection trolley on the track is improved, the technical problems that in the prior art, a track inspection trolley cannot stably run on a fat-edge road section of a track, so that the track gauge measurement precision is reduced, and a guiding structure is lacked and is difficult to install and position on the track are solved.

    本发明提供一种测量轮装置及轨检小车,测量轮装置包括固定座、轮轴组件及测量轮,轮轴组件设于固定座的内部,测量轮通过轮轴组件转动设于固定座的下端;测量轮包括测量部、导向部及避让部,测量部周向设于测量轮的外壁,测量部朝向固定座的一侧设置避让部,测量部的另一侧设置导向部。通过在测量轮上设置避让部避让轨道肥边,提高了轨检小车在轨道上运行的平稳性,进一步地,在测量部的另一侧设置导向部,通过导向部对轨检小车进入或退出工作状态导向,提高轨检小车在轨道上的安装效率,解决了现有技术中轨检小车无法在轨道的肥边路段上平稳运行导致轨距的测量精度下降,以及缺少导向结构难以安装定位于轨道上的技术问题。
