Background technology
In recent years, along with the increase of urban population and the rapid expansion of city size, urban track traffic obtains fast development, and increasing subway, light rail circuit constantly occur, and the urban track traffic mileage constantly rises.Along with the continuous development of track traffic, increasing circuit intersection, parking lot, rolling stock section occur, and the quantity that makes track switch is also in continuous rising; Bring easily simultaneously to people in track traffic, also have some problems: rail is hit greatly between switch area, and vibration noise is big; For reducing wearing and tearing, it is many that lubrication oil is smeared between switch area, and the fastener cushion is fragile, but traditional sulfuration adhesion type fastener can't separate, and can't change in case cushion damages, and can only change whole fasteners, and maintenance cost is very high.
The utility model content
The utility model proposes a kind of track traffic with removable steel rail vibration damping fastener for solving the problems of the technologies described above.
The utility model adopts following technical scheme for accomplishing the foregoing invention task:
A kind of track traffic mainly comprises rail, is used to limit spring base I, upper strata spring and the track gauge block I that rail is vertical, horizontal direction moves with removable steel rail vibration damping fastener; Described spring base I, upper strata spring and track gauge block I are positioned at the both sides of each one steel rail, and an end of said upper strata spring is withheld on rail through the track gauge block I, and the other end is connected on the spring base I that is positioned on the iron plate; Between rail foot surface and last iron plate, the upper strata cushion is set; Have spring base II, lower floor's spring and track gauge block II respectively in the both sides of last iron plate; One end of said lower floor spring is positioned on the spring base II, and the other end is withheld the two ends on last iron plate through the track gauge block II.
Described spring base II is positioned at down on the iron plate, be formed in one structure or connect one of spring base II and following iron plate, and described time iron plate is connected on the sub rail foundation through railway spike, between last iron plate and following iron plate, is provided with lower floor's cushion.
Described spring base II is connected on the sub rail foundation, between last iron plate and sub rail foundation, is provided with lower floor's cushion.
A kind of track traffic that the utility model proposes has spring base II, lower floor's spring and the track gauge block II that is used to withhold iron plate with removable steel rail vibration damping fastener in the both sides of last iron plate; One end of said lower floor spring is positioned on the spring base II, and the other end is withheld the two ends on last iron plate through the track gauge block II; Can dismantle upper strata cushion, lower floor's cushion, last iron plate, following iron plate easily, the component that damage are changed separately, keeped in repair, reduce maintenance cost and workload; Lower floor's cushion is set, has reduced the vibrations noise that has caused when driving a vehicle, prolonged the application life of rail.
