The invention is suitable for the technical field of urban rail vehicles, and provides an apron board limiting device of a rail train and the rail train. The apron board limiting device of the rail train comprises a train body, an apron board and an apron board mounting piece; and one of the apron board and the apron board mounting piece is provided with an arc-shaped slide way part, the other one of the apron board and the apron board mounting piece is provided with a sliding piece, and the sliding piece is located in the arc-shaped slide way part and is in sliding fit with the arc-shaped slide way part to limit the apron board. According to the apron board limiting device of the rail train, the arc-shaped sliding way part is arranged on one of the apron board and the apron board mounting piece, the sliding piece is arranged on the other one of the apron board and the apron board mounting piece, and the sliding fit between the sliding piece and the arc-shaped sliding way part is used for replacing a safety lifting rope and limiting the limiting position of the apron board, so that the problem of abnormal sound caused by collision between the apron board limiting device and the apron board or the car roof is solved, and the risk that the apron board limiting device is tangled with foreign matter such as birds and plastic bags is reduced.
本发明适用于城轨车辆技术领域,提供了一种轨道列车的裙板限位装置及轨道列车,轨道列车的裙板限位装置包括车体、裙板以及裙板安装件;所述裙板和所述裙板安装件的其中之一设有弧形滑道部,所述裙板和所述裙板安装件的其中另一设有滑动件,所述滑动件位于所述弧形滑道部内并与所述弧形滑道部滑动配合以对所述裙板进行限位。本发明提供的轨道列车的裙板限位装置,通过在裙板和裙板安装件的其中之一设置弧形滑道部并在裙板和裙板安装件的其中另一设置滑动件,利用滑动件和弧形滑道部的滑动配合来代替安全吊绳和限制裙板的极限位置,避免了裙板限位装置与裙板或车顶碰撞发生异响的问题,减少裙板限位装置与飞鸟、塑料袋等异物缠结的风险。
