Compared with the traditional line running by depending on the creeping of the wheel rail, the crawler type crawling vehicle has the remarkable characteristics that a rack rail parallel to the steel rail is laid in the middle of the rail, generally, the rack is arranged, and meanwhile, a matched meshing gear is arranged on the vehicle. When the vehicle runs on a large slope section, the meshing force between the gear and the rack can overcome the problem of insufficient adhesive force between the steel wheel and the steel rail, so that the vehicle has large climbing capacity.
Foreign tooth rail traffic system mainly used mountain area tourism adopts the tiny fragments of stone, coal, etc. track bed longitudinal stability poor, and the tiny fragments of stone, coal, etc. is easy for the landing, and circuit maintenance work load is big, and the maintenance cost is high. The domestic tooth rail railway mainly serves in the tunnel of the mining area, the off-line foundation structure is stable, the temperature difference between the track structure and the tunnel structure is small, the telescopic force is small, and the tooth rail railway is not laid on a bridge.
When the tooth-track railway is laid on the viaduct, the bridge generates longitudinal displacement due to temperature change or train load, drives the ballastless track bed and applies longitudinal force to the steel rail and the rack through the fastener system; the length of a common rack is short, the joint is connected by a bolt, under the action of longitudinal force, the track seam at the joint of the rack near a beam seam is expanded or reduced, the meshing effectiveness of the rack is influenced, and the tooth jacking phenomenon can occur in serious conditions, so that the driving safety is influenced.
