The invention discloses a rotatable high-speed train pantograph device which comprises a pantograph and a rotating mechanism, the pantograph is fixedly installed on the rotating mechanism, and the rotating mechanism is fixedly installed on a high-speed train body; the rotating mechanism comprises a rotating support, a base and a stepping motor, the rotating support is connected to the base in a sleeving mode through a bearing and can rotate around the base, an annular gear and a driving gear are installed on the rotating support, an output shaft of the stepping motor is connected with the driving gear, and the driving gear and the annular gear are installed in an engaged mode; the base is installed on the high-speed train body through a fastening assembly. According to the rotatable high-speed train pantograph device, the pantograph bears the same pneumatic lifting force and small running resistance when a train runs upwards or downwards, and the purpose of reducing energy consumptionis achieved.
本发明公开了一种可旋转的高速列车受电弓装置,包括受电弓和旋转机构,所述受电弓固定安装在所述旋转机构上,所述旋转机构固定安装在所述高速列车车体上;所述旋转机构包括旋转支座、基座和步进电机,所述旋转支座通过轴承套接在所述基座上并能绕基座转动,所述旋转支座上安装有环形齿轮和驱动齿轮,所述步进电机的输出轴与所述驱动齿轮连接,所述驱动齿轮和环形齿轮啮合安装;所述基座通过紧固组件安装在所述高速列车车体上。本发明可旋转的高速列车受电弓装置,使得受电弓在列车上行运行或下行运行时受到相同的气动抬升力及较小的运行阻力,达到降低能耗的目的。
