The invention discloses an aerodynamic force adjusting mechanism for a high-speed pantograph, the adjusting mechanism is mounted on an upper arm rod and a balance arm of the pantograph, when the pantograph rising height of the pantograph is changed, the angle between the balance arm and the upper arm rod is changed, a four-bar mechanism composed of the balance arm, the upper arm rod, a connecting rod and a guide plate mounting rod is driven to move, and the guide plates fixed on the guide plate mounting rods have different attack angles, so that different aerodynamic lift forces are realized along with the change of the pantograph lifting height, and the aerodynamic force of the high-speed pantograph is adjusted. The aerodynamic force adjusting mechanism has the advantages of being compact in structure, light in weight, reliable in structure, small in installation space and the like, the problem that an existing high-speed pantograph is different in aerodynamic lifting force at different working heights can be solved, and safe, reliable and normal running of a G-series high-speed train is guaranteed.
本发明公开了一种高速受电弓用气动力调整机构,该调整机构安装于受电弓的上臂杆和平衡臂上,当受电弓的升弓高度变化时,平衡臂与上臂杆之间的角度发生变化,驱动由平衡臂、上臂杆、连杆、导流板安装杆组成的四连杆机构运动,导流板安装杆上固定的导流板随之具有不同的攻角,从而实现随着升弓高度变化具有不同的气动升力,对高速受电弓的气动力进行调节。具有结构紧凑、重量轻、结构可靠、安装空间小等特点,能够解决目前高速受电弓在不同工作高度下气动力抬升力不同的问题,保证动车组的行车安全、可靠、正常运行。
