The invention provides a novel rail train ring grinding grounding device mounting structure which comprises a carbon brush II tightly attached to the left side of a carbon brush I, and the carbon brush II is hidden in a shell; the design that the first carbon brush and the second carbon brush are tightly attached is adopted, the first carbon brush and the second carbon brush can be in contact with a friction ring on a train axle at the same time during transposition, stable transition is formed, the situation that the contact area is reduced and contact fails due to transposition time difference is avoided, the integrity of a conductive loop is guaranteed, and the service life of the conductive loop is prolonged. Meanwhile, a cuboid protrusion is arranged on one side of the second carbon brush, the contact area of the second carbon brush and the friction ring is increased, fluctuation of current caused by transposition action is reduced, and safe use of electric appliances in a train is guaranteed.
本发明提供一种新型轨道列车环磨接地装置安装结构,包括碳刷一的左侧紧密贴合有碳刷二,碳刷二隐藏设置于壳体的内部;本发明采用碳刷一与碳刷二紧密贴合的设计,碳刷一与碳刷二换位时能够同时与列车车轴上的摩擦环保持接触,形成平稳过渡,避免出现换位时差导致接触面积减小且接触失效的情况,保障了导电回路的完整性,同时碳刷二的一侧设置有长方体凸起,增加碳刷二与摩擦环接触的面积,降低换位动作对电流造成的波动,保障列车内用电器的安全使用。
