Novel turnout for urban rail transit
The invention relates to a novel turnout of urban rail transit, which comprises a straight stock rail, a curved switch rail, a linear switch rail, a curved stock rail, a straight guide rail, a lateral guide rail and a combined frog, the curved switch rail, the curved stock rail and the lateral guide rail adopt a guide curve with the radius larger than or equal to 680m, and the radius of the curved switch rail, the radius of the curved stock rail and the radius of the lateral guide rail are the same. The frog angle of the combined frog is smaller than the frog angle of the twelfth turnout and larger than the frog angle of the eighteenth turnout. The curve radius is larger than or equal to 680 m, and the frog angle is smaller than the frog angle of the twelfth turnout and larger than the frog angle of the eighteenth turnout, so that the lateral passing speed and the straight passing speed can be increased, it can be guaranteed that when a train passes through the turnout at the lateral speed of 70 km/h, the comfort index of the train does not exceed the limit, and the lateral passing speed of the turnout can be larger than or equal to 70 km/h; the requirement of 30 pairs/h turn-back capacity of eight A-type vehicle marshalling in China can be met, and the higher requirement can be met.
本发明涉及一种城市轨道交通的新型道岔，包含直基本轨、曲线尖轨、直线尖轨、曲基本轨、直向导轨、侧向导轨和组合辙叉，所述曲线尖轨、曲基本轨和侧向导轨采用半径大于或等于680m的导曲线，所述曲线尖轨、曲基本轨和侧向导轨的半径相同，所述组合辙叉的辙叉角小于12号道岔的辙叉角、大于18号道岔的辙叉角。其曲线半径大于或等于680m，且辙叉角小于12号道岔的辙叉角、大于18号道岔的辙叉角，使得能够提高侧向通过速度和直向通过速度，能够保证列车以侧向70km/h速度通过道岔时，列车舒适性指标不超限，能够使得道岔的侧向通过速度大于或等于70km/h，能够满足国内8辆A型车编组“30对/h”折返能力需求，且能够达到更高的需求。
