The invention relates to the technical field of rail transit, and discloses an anti-separation sliding plate for a high-speed rail pantograph, the anti-separation sliding plate comprises a middle shaft rod, one side of the middle shaft rod is fixedly provided with an upper support, two ends of the middle shaft rod are fixedly provided with two suspension supports, and one sides of the exteriors of the two suspension supports are fixedly provided with connecting shafts. According to the pantograph sliding plate, air flow generated during driving passes through the side air guide plate, the lower air guide plate and the sliding plate, the air flow intensively flows into the bottom end of the sliding plate, the speed of the air flow is increased, a negative pressure cavity is formed in the wire suction hole, negative pressure adsorption is conducted on a contact wire, and the problem that the pantograph sliding plate and the contact wire fall off is solved; a pressure difference is formed between the top end and the bottom end of the sliding plate, the dynamic interaction force between the contact wire and the sliding plate is effectively enhanced, the electric energy generation effect is effectively enhanced, the sliding plate is designed to be the arc-shaped edge, the air resistance borne by the sliding plate is reduced, and the mechanical consumption of the pantograph head of the pantograph can be effectively reduced.
本发明涉及轨道交通技术领域,且公开了一种高铁受电弓用防脱离式滑板,包括中轴杆,所述中轴杆的一侧固定安装有上支架,所述中轴杆的两端固定安装有两个悬承架,两个所述悬承架的外部一侧固定安装有连接轴。本发明通过利用行驶时所产生的风流,通过侧导风板、下导风板及滑板,令风流集中流入滑板底端,使风流速度加快,使吸线孔内部形成负压空腔,对接触导线进行负压吸附,避免受电弓滑板与接触导线发生脱落的问题,同时,滑板的顶端与底端形成压强差,有效加强接触导线与滑板之间的动态相互作用力,有效的增强电能的产生效果,通过将滑板设计为弧形边缘,则滑板所受空气阻力变小,可有效降低受电弓的弓头的机械消耗。
