According to the pantograph balancing device and the pantograph, the balancing device (including a large air guide plate and a small air guide plate) is arranged on a pantograph head of the pantograph, so that the pantograph head of the pantograph is balanced under the influence of high-speed airflow; the large air deflector can counteract the contact force difference value (the contact force difference value is the difference between the contact force in an airflow-free state and the contact force under the influence of airflow) of the pantograph head, it can be guaranteed that under the action of high-speed airflow, the lifting force in the opening direction is consistent with the lifting force in the closing direction of the pantograph, that is, the high-speed airflow does not affect the total lifting force of the pantograph, and therefore the pantograph head can be stably lifted. The contact force difference value can be balanced, and stable and effective work of the pantograph is guaranteed; the small air deflector can offset overturning torque generated by the pantograph after being affected by airflow, it is guaranteed that the contact force between the front sliding plate and the contact net is consistent with the contact force between the rear sliding plate and the contact net, and the problems of inconsistent abrasion and the like are avoided.

    本发明公开了一种受电弓的平衡装置及受电弓,通过在受电弓的弓头上设置平衡装置(即包括大导风板和小导风板),在高速气流的影响下,大导风板能够抵消受电弓弓头的接触力差值(接触力差值即无气流状态下与有气流影响下的接触力的差),能保证受电弓在高速气流作用下,开口方向与闭口方向的抬升力一致,也就是高速气流对受电弓总的抬升力不产生影响,即能够平衡接触力差值,保证受电弓的稳定和有效工作;小导风板能够抵消受气流影响后受电弓产生的翻转力矩,保证前后滑板与接触网的接触力一致,避免磨损不一致等问题的产生。
