Rail-spanning stepping type ballast excavating machine
The invention relates to a rail-spanning stepping type ballast excavating machine. A movable worktable and a stepping working unit are arranged on a transverse guide rail; a horizontal working oil cylinder and a vertical movable frame are mounted above the movable worktable; a cantilever and an inclined angle overturning oil cylinder are arranged on the vertical movable frame; the inclined angle overturning oil cylinder and the cantilever are hinged to a ballast excavating working mechanism respectively; the stepping working unit and the movable worktable are controlled by the horizontal working oil cylinder to do intermittent movement, so that the ballast excavating working mechanism moves in a single direction; a piston rod of a vertical working oil cylinder mounted on the vertical movable frame does reciprocating motion to drive a ballast excavating cutter tooth plate of the ballast excavating working mechanism to cut in and leave away from a railway ballast; the inclined angle overturning oil cylinder is used for adjusting a working angle of the ballast excavating working mechanism; ballast excavating teeth, a material guide plate and a side baffle on the ballast excavating cutter tooth plate are reasonably arranged and are mutually matched, so that continuous and efficient excavation and lifting are realized; the construction efficiency is improved, the working performance is reliable and the construction quality is high; the rail-spanning stepping type ballast excavating machine is suitable for industrial popularization.
