The invention discloses a pantograph for a light rail subway and a railway vehicle. The pantograph comprises a base, a lower arm, an upper arm, a lower guide rod, a pantograph lifting driving device, an upper guide rod and a pantograph head assembly. One end of the upper arm structure elbow is welded with the longitudinal strut, and the other end of the upper arm structure elbow is welded with the upper cross pipe, so that the distance between the upper arm and the sliding plate is enlarged, and the problem that the distance between the upper arm and the sliding plate of the pantograph in a tunnel is too small is solved; the lower guide rod structure adopts a double-lower guide rod mode and forms a triangular shape with the base, so that the stress is balanced and stable; a supporting shaft for connecting the lower arm and the base adopts a crankshaft mode, so that the pantograph falling height and the minimum working height of the pantograph can be reduced, and the capital construction cost is saved; the lower arm is connected with the driving device in a cam form, so that the moment is more balanced when the pantograph is lifted, and the risk that a connecting bolt is broken due to non-uniform shearing force is avoided; in the operation process of the pantograph, the driving device is in a disengaged state, the current collection of the pantograph is stable, the work is reliable, and the daily maintenance is more convenient.
本发明公开了一种轻轨地铁用受电弓及轨道车辆,包括底座、下臂、上臂、下导杆、升降弓驱动装置、上导杆和弓头组件。上臂结构弯管一端与纵支柱焊接,另一端与上交叉管焊接,拉大了上臂与滑板的间距,避免了受电弓在隧道内上臂与滑板间距过小的问题;下导杆结构采用双下导杆的方式,与底座呈三角形状,受力均衡且稳定;下臂与底座连接的支撑轴采用曲轴的方式,可以使受电弓落弓高度和最小工作高度降低,节约基建成本;下臂与驱动装置连接为凸轮形式,保证升降弓时力矩更加均衡,避免了连接螺栓因受剪切力不均而产生断裂的风险;受电弓在运行过程中,驱动装置为脱离状态,受电弓受流稳定,工作可靠,日常维护更加便捷。
