The utility model discloses a sliding device for railway tunnel punching equipment. Comprising a supporting frame, a sliding base arranged on the supporting frame in a sliding mode, a driving piece, a tensioning base, a driving chain wheel arranged on the driving piece, a driven chain wheel rotationally arranged on the tensioning base and a transmission chain which bypasses the driving chain wheel and the driven chain wheel and is connected with the two opposite sides of the sliding base, wherein the driving piece and the tensioning base are fixedly arranged on the supporting frame. When the tensioning seat tensions the transmission chain, the driving piece is started, the driving piece drives the driving chain wheel to rotate synchronously, the driving chain wheel drives the sliding seat to slide relative to the supporting frame through the transmission chain, the railway tunnel punching equipment moves synchronously in a tunnel along with the sliding seat, the time occupied by frequently folding and unfoldi
