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.

This invention discloses a point cloud nesting cutting device and method for a dead-end pipe, comprising two cutting robots and two tracks for each of the cutting robots to traverse; the two ends of the tracks are connected by a snap-fit ​​device to form a ring structure surrounding the material pipe; it also includes a handheld 3D scanning device for scanning the dead-end pipe, the cutting torch, and the tracks to generate point cloud data with spatial position information; and a first calculation module for calculating the cutting parameters of the two pipes based on the point cloud data obtained by the handheld 3D scanning device. The advantages of this invention are: highly automated calculation process; low operational difficulty; and the addition of 3D scanning of the material pipe and tracks, enabling automatic deviation correction of the cutting robots.
