The invention relates to a rolling type contact pantograph device of an electrified train, which comprises a rolling conductive cylinder (1), a rotating bearing (2), a rotating support shaft seat (3), a balance support frame (4) and a transverse bracket (5), the rolling conductive cylinder (1) is arranged on the rotating support shaft seat (3) through the rotating bearing (2), the rotating support shaft seat (3) is arranged on the transverse bracket (5) through the balance support frame (4), and the balance support frame (4) is arranged on the transverse bracket (5). And the transverse bracket (5) is connected with a pantograph. Compared with the prior art, sliding friction contact between an overhead line system line and a pantograph sliding plate is changed into rolling friction contact in the listed operation direction in the pantograph-catenary contact relation, and contact mechanical friction loss of the overhead line system line and the sliding plate is greatly reduced; meanwhile, due to the change of the relative movement of the friction pair, the dynamic flutter impact of relative abnormal irregularity, hard spots and the like of a pantograph net system is reduced, the power receiving stability is improved, the current receiving quality is improved, the arc abrasion and the like of the pantograph net are reduced, and the service life of the pantograph net is prolonged.
本发明涉及一种电气化列车滚动式接触受电弓装置,包括滚动导电筒(1)、转动轴承(2)、转动支承轴座(3)、天平支撑架(4)和横托架(5),所述滚动导电筒(1)通过转动轴承(2)安装在转动支承轴座(3)上,所述转动支承轴座(3)通过天平支撑架(4)安装在横托架(5)上,所述的横托架(5)连接受电弓。与现有技术相比,本发明从弓网接触关系上在列出运行方向从接触网线与受电弓滑动板之间的滑动摩擦接触改变为滚动摩擦接触,大大地降低网线及滑板的接触机械摩擦损耗,同时由于摩擦副相对运动的改变降低弓网系统相对异常不平顺及硬点等的动态颤振冲击,提高受电平稳性,改善受流质量,从而也降低受电弓网的电弧磨损等,提高弓网寿命。
