The invention provides a railway maintenance locomotive for maintaining rail defects. The railway maintenance locomotive comprises a locomotive body, a power cavity is formed in the locomotive body, arotating shaft is rotatably connected with the inner wall of the lower side of the power cavity, the upper end of the rotating shaft is located in the power cavity, the lower end of the rotating shaft is located on the lower side of the locomotive body, the upper end of the rotating shaft is in spline connection with a speed adjusting shaft sleeve, and two low-speed gears are fixedly connected with the speed adjusting shaft sleeve. Defects on the upper surface of a rail are detected through a detection wheel while the locomotive runs along the rail, and when the rail has protrusions, the protrusions are ground off through a grinding wheel; when the rail is sunken, the sunken part is fully filled with molten rail supplementing iron wire, so that the sunken part is completely covered with the rail supplementing iron wire, then the redundant rail supplementing iron wire is ground off through the grinding wheel, and the upper surface of the rail is restored to be flat; through the meshingbetween a low-speed gear and a transmission gear and the switching of the meshing between a high-speed gear and a driven gear, the change of the running speed of the rail maintenance locomotive is realized.
本发明公开的一种检修铁轨缺陷的铁路维修机车，包括车身，所述车身内设有动力腔，所述动力腔下侧内壁上转动连接有转动轴，所述转动轴的上端位于所述动力腔内、下端位于所述车身的下侧，所述转动轴上端花键连接有调速轴套，所述调速轴套上固接有两个低速齿轮；本发明在沿着铁轨行驶的同时通过检测轮检测铁轨上表面的缺陷，当铁轨有凸起时，通过磨砂轮打磨掉凸起部分；当铁轨有凹陷时，通过熔融的补轨铁丝对凹陷进行饱满填充，使得补轨铁丝完全覆盖凹陷，之后通过磨砂轮打磨掉多余的补轨铁丝，使得铁轨的上表面恢复平整；通过低速齿轮和传动齿轮之间的啮合、高速齿轮和从动齿轮之间的啮合的切换，实现铁轨维修车行驶速度的变化。
