The invention relates to an overhead contact rail, and belongs to equipment for supplying power to an electric locomotive in urban rail transit. An overhead contact rail 1 with a cavity 15 is mainly adopted and is arranged on a cross beam 5 below the top of a subway tunnel through a lifting hook and an insulator 4; a fishplate 16 is adopted to connect adjacent overhead contact rails 1 to form an external intermediate joint; an included angle of 75 degrees is formed between an end surface notch 19 of the overhead contact rail 1 and a longitudinal center line 20; stainless steel 9 with a bowl-shaped cross section of the overhead contact rail 1 is welded with two stainless steel bands 10 and then fastened on an aluminum profile 8, and rivets 18 are arranged on two sides of the overhead contact rail 1 at intervals in the longitudinal direction to enhance the longitudinal binding force of steel and aluminum. The pantograph is convenient to install and connect, long in service life, high inthree-way rigidity, small in electric spark between the pantograph and the current supply surface of the stainless steel 9 of the overhead contact rail 1, and suitable for high-speed operation of subway electric locomotives.

    本发明涉及一种架空接触轨,属于城市轨道交通对电力机车供电的设备。其主要采用带空腔15的架空接触轨1,经吊钩和绝缘子4安装在地铁隧道顶部下方的横梁5上;采用鱼尾板16来连接相邻的架空接触轨1,成为外置的中间接头;架空接触轨1的端面切口19与其纵向中心线20呈75°夹角;架空接触轨1的截面为碗形的不锈钢9与二条不锈钢带10焊接后紧固在铝型材8上,纵向每隔一段距离在二侧以铆钉18增强钢与铝的纵向结合力。本发明安装和连接方便,寿命长,三向刚度大,受电弓与架空接触轨1的不锈钢9的授流面之间电火花小,适用于地铁电力机车高速运行。
