The invention discloses a rotary pantograph head. In the rotary pantograph head, a roller is configured to make contact with a contact line for electric conduction; a rotating shaft penetrates throughthe roller and synchronously rotates with the roller; a conductive end cover is arranged at the end part of the rotatable rotating shaft in a sleeve mode, a magnetic fluid sealing device is connectedwith and seals the rotating shaft and the conductive end cover so as to form a rotary dynamic sealing closed cavity between the conductive end cover and the magnetic fluid sealing device, liquid metal is contained in the closed cavity, and the liquid metal is wrapped around the end part of the rotating shaft and can rotate.

    本发明公开了一种旋转式的受电弓弓头,旋转式的受电弓弓头中,滚筒配置成与接触线接触导电;旋转轴贯穿所述滚筒且与所述滚筒同步旋转;导电端盖套设在可旋转的所述旋转轴的端部,磁流体密封装置连接并密封所述旋转轴和导电端盖以在导电端盖和磁流体密封装置之间形成旋转动密封的密闭腔,液态金属容纳在所述密闭腔,所述旋转轴的端部包裹在所述液态金属中且可旋转。
