This invention discloses a railway rail rust removal device and method based on unmanned aerial vehicles (UAVs), belonging to the field of railway rail rust removal technology. The device includes a UAV body, a power supply, a central controller, and connecting devices. The UAV body is connected to a rail laser rust removal device, a lidar device, and a Beidou positioning differential antenna via the connecting devices. The lidar device scans the space below and in front of the UAV and constructs spatial data of the rail surface model and the obstacle model within the UAV's working space. The rail laser rust removal device is used to achieve precise rust removal of the rail based on the rail surface model spatial data constructed by the lidar module. This invention solves the problems of poor rust removal effect, difficulty in accurately identifying rusted areas on the rail, low efficiency, and poor safety in existing railway rail rust removal operations.

The application discloses a kind of automatic centering semi-autogenous mill feeding mechanism, it includes feeding trolley component, including bottom plate, first roller being symmetrically rotatably installed on the bottom plate, support frame being symmetrically fixed on the bottom plate, material bucket being fixed on the support frame and feeding pipe being connected on the material bucket, movable baffle is inserted on the feeding pipe;To-be-driven component, including abutment block being fixed on the support frame, first rack being symmetrically fixed on the outer wall of the abutment block, arc-shaped slot being symmetrically opened on the outer wall of the abutment block, ball being rotatably installed in the inner cavity of the arc-shaped slot and pull plate being symmetrically fixed on the outer wall of the abutment block;Trailer assembly;Ball drive component is arranged on the trailer assembly, the ball can be driven to rotate, and feeding trolley component is driven to move to base, so as to realize that trailer is to feeding trolley Automatic centering, feeding trolley does not need to be manually pushed.
