AI Technical Summary

Technical Problem

The existing ballastless tracks are difficult to effectively prevent trains from derailing and capsizing in extreme cases, and they are insufficient in structural adaptability and maintenance.

Method used

The beam-type ball-free track design with steel guard plate is adopted. The track beam is restricted vertically and horizontally through the limiting boss and steel guard plate, and combined with the continuous shoulder block and the beam end composite energy-absorbing adjustment pad, providing multi-level safety protection.

Benefits of technology

It significantly enhances the anti-derailment overturning ability, maintains the integrity of the cross-section of the track beam, improves the overall strength and durability of the track beam, and improves construction efficiency and maintenance adaptability.

Abstract

The invention belongs to the technical field of rail traffic, and discloses a beam-type ballastless track containing steel guard plates, which comprises a track supporting seat, the track supporting seat comprises two truss pedestals and a steel bar truss, the two truss pedestals are connected through the steel bar truss, the top ends of the truss pedestals are fixedly provided with limiting bosses and the two steel guard plates, and the steel guard plates are arranged on the limiting bosses; a lateral limiting cushion block is filled between the steel protection plate and the limiting boss; the two ends of the track beam abut against the two adjacent limiting bosses respectively, two longitudinally-arranged continuous blocking shoulders are arranged on the top end face of the track beam, and the length of the continuous blocking shoulders is equal to that of the track beam; the beam end composite energy absorption adjusting base plate is mounted in a gap between the end part of the track beam and the limiting boss; and the under-beam support damping adjusting base plate is pressed between the bottom end surface of the end part of the track beam and the top end surface of the truss pedestal. The device can meet the strict requirements of high-speed railways for safety, smoothness and stability, can effectively prevent the train from overturning and rushing out of the line under the emergency working conditions such as train derailment, and reduces casualties and property loss.
