The invention belongs to the technical field of railway transportation, and particularly relates to a linkage guide rod type platform extension plate upturning mechanism which comprises an extension plate and a guide rod, and one side of the extension plate in the length direction is hinged to the top of a platform; a first movement guide rail extending in the width direction of the extension plate is arranged on the bottom face of the extension plate, a second movement guide rail extending in the vertical direction is arranged on the side face of the platform, and the upper end of the guide rod is slidably installed on the first movement guide rail. The lower end of the guide rod is slidably installed on the second movement guide rail and connected with a driving mechanism used for driving the guide rod to move along the second movement guide rail. The driving mechanism drives the lower end of the guide rod to move up and down along the second movement guide rail, and the guide rod has a clockwise/anticlockwise rotation trend relative to the first movement guide rail, so that the extension plate is driven to be overturned upwards to be unfolded or rotated downwards to be folded, and structural stability and passenger safety are ensured; and the platform does not need to be installed after being excavated, and interference to a main body structure of the platform is reduced.
本发明属于铁路运输技术领域,具体涉及一种联动导杆式站台延伸板上翻机构,包括延伸板以及导杆,延伸板长度方向的一侧与站台的顶部铰接;延伸板的底面上设置有沿其宽度方向延伸的第一运动导轨,站台的侧面上设置有沿竖直方向延伸的第二运动导轨,导杆的上端滑动安装于第一运动导轨上,导杆的下端滑动安装于第二运动导轨上且与用于驱动其沿第二运动导轨运动的驱动机构连接。本发明通过驱动机构带动导杆的下端沿第二运动导轨上下移动,导杆相对于第一运动导轨有一个顺/逆时针方向转动的趋势,从而带动延伸板向上翻转展开或向下转动收起,确保结构稳定和乘客安全,且本发明不需要对站台进行挖空作业再安装,减少了对站台主体结构的干扰。
