The invention discloses a lifting type pantograph of a heavy truck based on an expressway. The pantograph comprises a pantograph body and the bottom frame of the pantograph body, the bottom frame of the pantograph body is installed on a lifting frame, the lifting frame comprises a static frame, a movable frame and a lifting driving system, the lifting driving system comprises a lead screw and a nut, the nut is fixed to the movable frame, and one end of the lead screw is connected with a driving motor. The lifting type pantograph has the advantages of being low in pantograph falling position, high in working position, simple in structure, high in reliability and the like, solves the problems that an electric heavy truck is small in vertical installation space and high in overhead line system line height, and achieves stable current collection of the heavy truck on an electrified expressway contact network.

    本发明公开了一种基于高速公路的重型卡车升降式受电弓,包括受电弓及其底架,受电弓的底架安装在升降框架上,升降框架包括静框架、动框架和升降驱动系统,升降驱动系统包括丝杆和丝母,丝母固定在所述动框架上,丝杆的一端连接有驱动电机。具有落弓位置低、工作位置高、结构简单可靠性高等优点,解决电动重型卡车垂向安装空间较小而同时接触网线高度较高的问题,实现重载卡车在电气化高速公路接触网上稳定受流。
