The invention relates to an installation of a rail fastener for a steel sleeper of mountain rail transit, which comprises the following steps:
the periphery of the iron seat and the steel sleeper are welded into a whole, when the steel sleeper is installed, firstly, the
The track gauge adjustment of the track fastener of the invention:
the width of bullet strip is realized through reasonable design, simultaneously through changing insulating gauge block. Wherein, the increase of the width of the elastic strip is realized by the sizes of R1, R2, R3 and L in the existing W-shaped elastic strip (see figure 4); the design of insulating gauge block has several kinds of different specifications, and the insulating gauge block thickness d of different specifications is different (see figure 6), and the insulating gauge block of different specifications is changed according to the roll adjustment volume of actual need during roll adjustment.
The longitudinal heightening of the rail fastener of the invention:
the height adjustment of the steel rail is realized by adjusting the height of the base plate, and the height-adjusted base plate is arranged below the rubber base plate (only the steel rail and the rubber base plate are adjusted to be high after the height-adjusted base plate is arranged). In view of the characteristics of the steel sleeper, the integral height adjustment can be realized by adjusting the installation height of the steel sleeper.
The track fastener has good insulating property:
the sleeve fastener realizes the insulation between the elastic strip and the steel rail through the insulating gauge block; the insulation between the steel rail and the steel sleeper is realized through the lower rail base plate.
The working principle of the invention is as follows:
due to the transportation convenience of the steel sleeper, the steel sleeper has great advantages in construction. The toggle piece isolates the steel rail from the sleeper through the rubber base plate and the gauge baffle (both are non-metal pieces), thereby providing enough insulating property. The rubber backing plate and the elastic strip provide enough damping performance for the rail. The T-shaped bolt is connected with the iron base (after welding), and provides enough buckling pressure for the track through the elastic strip. Meanwhile, the toggle piece has better distance and height adjusting capability.
