Cross crossover turnout for tramcar and light rail line
The invention provides a cross crossover turnout for tramcars and light rail lines. The cross crossover turnout comprises stock rails and switch rails. The stock rails which are parallel at intervals and the switch rails of the rhombic cross structures intersect to form four single frogs. The four single frogs comprise switches, acute frogs, obtuse frogs and guard rails; the distance L between the rail centers of the spaced and parallel stock rails ranges from 3600 mm to 4000 mm; the radius R of a guide curve of the switch rail is 45000 to 60000 mm; the frog angle alpha of the single frog is 8 degrees, 7 '48 ''to 9 degrees, 27' 44''; the switch rail is directly connected with the obtuse frog, and the obtuse frog is directly connected with the acute frog without a transfer rail; a straight stock rail working edge and a curved stock rail working edge of the stock rail respectively deviate outwards by a distance D and are tightly attached to and connected with the end part of the switch rail so as to thicken the switch rail; and the switch rail is seamlessly and directly connected with the single frog to form an elastic bendable switch rail structure. The safety and stability of a vehicle when the vehicle passes through the cross crossover are effectively improved; the service life of cross crossover parts is effectively prolonged; and the construction requirements of seamless turnouts are met.
提供一种用于有轨电车及轻轨线路的交叉渡线道岔，包括基本轨和尖轨；间隔平行的基本轨与菱形交叉结构的尖轨相交构成四个单开辙叉；四个单开辙叉包括转辙器、锐角辙叉、钝角辙叉以及护轨；间隔平行的基本轨轨心间距L为3600～4000mm；尖轨的导曲线半径R为45000～60000mm；单开辙叉辙叉角α为8°7＇48＂～9°27＇44＂；尖轨与钝角辙叉，钝角辙叉与锐角辙叉均直接相连不设置转接轨；基本轨包括的直基本轨工作边以及曲基本轨工作边分别向外偏移距离D并与尖轨端部密贴相连以加粗尖轨；尖轨与单开辙叉无缝直接相连以组成弹性可弯尖轨结构。本发明有效提高车辆通过交叉渡线时的安全性和平稳性；有效提提高交叉渡线零部件的使用寿命；满足无缝道岔建设要求。
