The utility model relates to a tie plate fastening switch sleeper bolt structure of a railway switch, which comprises a bolt which is allocated with a cover plate, a tie plate which is formed by an upper plate, a lower plate and a rubber spacer which is clamped between the upper plate and the lower plate, and a lifting tie plate which is arranged under the tie plate, wherein the rubber spacer is arranged under the cover plate, and a limiting liner bushing is arranged in a tie plate bolt hole which is matched with the bolt. The tie plate fastening switch sleeper bolt structure of a railway switch can control the rubber spacer under a plate to be deformed in a reasonable range through reasonably choosing the length of the limiting liner bushing, which guarantees the axial force of a switch sleeper bolt when the elasticity of an elastic layer under a plate is fully kept, a certain vertical pressure is generated on the tie plate and the ride comfort of a track is improved, effectively improves the force condition of the switch sleeper bolt, and prevents the switch sleeper bolt from loosening.
