This utility model discloses a
lithium-
ion battery-powered multifunctional rail
grinding machine, including a frame, and
grinding components, a feed adjustment component, a contour wheel component, a
handrail component, and a
power battery pack component mounted on the frame. A
pressure sensor monitors the
grinding pressure in real time, and the feed adjustment component automatically adjusts the pressure between the
grinding wheel and the rail to ensure the grinding pressure is always maintained at the optimal level. The feed method uses a motor-driven threaded transmission, which is simple, reliable, and offers high adjustment precision. The
handrail component is reasonably designed, allowing for flexible adjustment of the grinding angle via an angle adjustment plate. Combined with the auxiliary wheel design, it can stably complete the grinding of the top, side, and curved surfaces of the rail. Powered by a
lithium battery, it is convenient for field operations. This utility model has a reasonable structure, is easy to operate, and can improve the quality and efficiency of rail grinding.
