High-speed train pantograph fairing device capable of achieving opening and closing functions
The invention relates to a high-speed train pantograph fairing device capable of achieving opening and closing functions. The device comprises a fairing, an automatic door and a driving mechanism. The driving mechanism comprises a bearing beam fixed on the vehicle body, a motor, a ball screw mechanism connected with the motor, a linear guide rail, a guide groove and a connecting rod mechanism; the connecting rod mechanism comprises a bottom support, a first bearing connecting rod, a second bearing connecting rod and two bearing pieces. The bottom support is connected with the ball screw mechanism, and a sliding block is arranged on the bottom support and matched with the linear guide rail. The first bearing connecting rod and the second bearing connecting rod are hinged to the two ends of the bottom support, and a guide wheel is installed on the first bearing connecting rod and arranged in the guide groove; the two bearing pieces are hinged to the first bearing connecting rod and the second bearing connecting rod correspondingly, and the top ends of the bearing pieces are fixedly connected with the automatic door. According to the device, when the pantograph is in a pantograph falling working condition, the automatic door is closed, the large opening in the air guide cover is closed, and the aerodynamic resistance and aerodynamic noise of a pantograph area on a car roof are reduced.
本发明涉及一种可实现开闭功能的高速列车受电弓导流罩装置，该装置包括导流罩、自动门、驱动机构；驱动机构包括固定在车体上的承载梁、电机、与电机连接的滚珠丝杠机构、直线导轨、导向槽、连杆机构；连杆机构包括底部支架、第一承载连杆、第二承载连杆和两个承载件；底部支架与滚珠丝杠机构连接，底部支架上设有滑块，滑块与直线导轨配合；第一承载连杆、第二承载连杆铰接于底部支架两端，第一承载连杆上安装有导向轮，导向轮设置在导向槽内；两个承载件分别铰接于第一承载连杆、第二承载连杆，承载件的顶端与自动门固连。该装置当受电弓处于落弓的工况时，自动门关闭，封闭住导流罩上的大开口，降低车顶受电弓区域的气动阻力和气动噪声。
