The invention relates to the technical field of carbon sliding plates, in particular to a pantograph carbon contact strip which comprises an aluminum bracket, a carbon strip, an air channel and an airpipe connector, the carbon strip is connected to the upper end face of the aluminum bracket in a fastened mode, the air channel and the air pipe connector are arranged in the carbon strip, and the air channel is communicated with the air pipe connector; the air channel is made of a copper pipe, the copper pipe is subjected to rotary cutting every 20 mm. The installation of an external aluminum strip air passage is reduced; installation time is saved, the air channel is internally arranged and is subjected to rotary cutting on the outer surface of a through pipe; if the sliding plate reaches the abrasion limit or large impact exists between the pantograph and the contact network line, due to the fact that the pantograph is damaged, compressed air in the air channel is discharged out of theair channel, the pressure is reduced, the automatic pantograph lowering device is started, the compressed air in the air channel is rapidly discharged, and the pantograph is rapidly separated from the contact network line. Not only can the pantograph lifting function be achieved, but also an early warning mechanism can be effectively played, a railway pantograph catenary can be better protected compared with an old sliding plate, and safe traveling of a locomotive is guaranteed.
本发明涉及碳滑板技术领域,更具体而言,涉及一种受电弓碳滑板,包括铝托架、碳条、气道和气管接头,所述碳条紧固连接在铝托架上端面,所述碳条内设置有气道及气管接头,所述气道与气管接头连通;所述气道采用铜管,所述铜管每20mm进行旋切,减少了外置铝条气道的安装,节约安装时间,将气道内置并在通管外表面进行旋切,如滑板达到磨损极限或受电弓与接触网线有较大冲击时,由于受电弓受损使气道内的压缩空气由气道内泄出,压力下降,使受电弓自动降弓装置启动,快速排出气道内的压缩空气,使受电弓快速脱离接触网线。不仅能满足升降弓作用,还能有效发挥预警机制,相对旧滑板能更好的保护铁路弓网,保障机车安全出行。
