The invention discloses an embedded sleeve type railway
fastener which is used for fixing a steel rail on a sleeper. The
fastener comprises an elastic strip, a
track gauge baffle, a baffle base, an embedded sleeve and a bolt
fastener. The baffle base is arranged at a top of the sleeper, the
track gauge baffle is clamped between the baffle base and a steel rail, the elastic strip is arranged on thetrack gauge baffle, the embedded sleeve is embedded in the sleeper, and the bolt fastener sequentially penetrates through the middle of the elastic strip and the
track gauge baffle from top to bottomand is screwed into the embedded sleeve; and the elastic strip is
omega-shaped, the elastic strip comprises an elastic strip middle limb and an elastic strip side limb which are integrally connected,a longitudinal section of the elastic strip middle limb is an arch structure, the elastic strip middle limb comprises a front end arc and a rear end arc which are integrally connected and in smooth transition, an arc
radius R1 is 32-34 mm, and the arc
radius R2 of the front end arc is 79-81 mm. According to the railway fastener, a problem of eccentric tension of a bolt in the prior art is effectively solved, a spike is prevented from being broken in a using process, and
pollution is not caused to an environment in a mounting process.
