The invention discloses a closed double-sliding-contact-surface third rail power supply structure. The power supply structure comprises a double-sliding-contact-surface contact rail, a protective cover, a current collector arm and a current collector boot head, wherein two sliding contact surfaces of the double-sliding-contact-surface contact rail are arranged in parallel, the protective cover annularly surrounds the double-sliding-contact-surface contact rail, an opening is formed in one side of the protective cover, one end of the current collector arm stretches out of the opening, the otherend of the current collector arm is elastically connected with a current collector shoe head, the current collector shoe head is used for making contact with the two sliding contact surfaces, and thecurrent collector arm can drive the current collector shoe head to slide along the sliding contact surfaces. The power supply structure is advantaged in that when a train is transversely displaced, as a transverse degree of freedom is formed between a current collector arm and the train, the current collector boot head is elastically connected with the current collector arm, the current collectorarm can be basically kept in the middle of the two sliding contact surfaces and cannot make contact with the opening of the protective cover, moreover, the contact force of the two sliding contact surfaces is constant all the time under high-speed movement, stable current collection is guaranteed, and the power supply structure further has properties of being simple in structure, low in manufacturing cost and good in high-speed adaptability.

    本发明公开了一种封闭式双滑触面第三轨供电结构,包括双滑触面接触轨、防护罩、集电器臂和集电器靴头,双滑触面接触轨的两个滑触面平行设置,防护罩环形包围双滑触面接触轨,防护罩的一侧设有开口,集电器臂的一端伸出开口,集电器臂的另一端弹性连接有集电器靴头,集电器靴头分别用于和两个滑触面相接触,集电臂能够带动集电器靴头沿着滑触面滑动。当列车发生横向位移时,由于集电器臂和列车之间具有横向自由度,集电器靴头和集电器臂弹性连接,集电器臂基本可以保持在两个滑触面的中间位置,而不会与防护罩的开口发生接触,同时在高速运动下两个滑触面的接触力始终恒定,保证受流稳定,本发明具有结构简单,造价低,高速适应性佳的优点。
