The invention discloses a buffer lifting type pantograph, and relates to the technical field of electric vehicle pantographs. The pantograph comprises a base, a lifting arm and a pantograph head, wherein the upper end of the lifting arm is connected with the pantograph head, a central rotating shaft at the lower end of the lifting arm is rotatably mounted on the base, and a spring pantograph lifting device and a pantograph falling cylinder for driving the central rotating shaft to rotate are arranged between the central rotating shaft and the base; the spring pantograph rising device overcomesdamping buffer force generated by intake and exhaust throttling of the pantograph falling air cylinder to drive pantograph rising, and pressure gas introduced into the pantograph falling air cylinderovercomes the damping buffer force and the acting force of the spring pantograph rising device to push out the piston rod to drive pantograph falling. The spring pantograph ascending device and the pantograph descending air cylinder can serve as power and damping for alternate exchange, and an auxiliary buffer device is not needed, so that the structural design is simplified, and the assembly cost is reduced.

    本发明公开了一种缓冲升降型受电弓,涉及电力车辆受电弓技术领域。本发明包括底座、升降臂和弓头,升降臂上端连接弓头,升降臂下端的中心转轴可转动地安装在底座上,中心转轴与底座之间设置有带动中心转轴转动的弹簧升弓装置和降弓气缸;其中,弹簧升弓装置克服降弓气缸由进排气节流产生的阻尼缓冲力驱动升弓,通入降弓气缸的压力气体克服阻尼缓冲力及弹簧升弓装置的作用力推出活塞杆驱动降弓。本发明的弹簧升弓装置与降弓气缸可作为交替互换的动力和阻尼,无需辅助缓冲装置,简化结构设计及降低装配成本。
