The invention discloses an adjustable step missing prevention plate for a platform door. The adjustable step missing prevention plate comprises a threshold, a step missing prevention plate body, quickrelease bolts and nuts. The step missing prevention plate body is arranged under the threshold, and the threshold and the step missing prevention plate body are connected and fixed through the quickrelease bolts and the nuts; and when the quick release bolts are unscrewed, the step missing prevention plate body can move front and back in the passenger in-out direction relative to the threshold so as to adjust the distance extending out of the edge of the threshold. According to the adjustable step missing prevention plate for the platform door, the distance of the step missing prevention plate extending out of the edge of the threshold can be steplessly adjusted within a certain range, so that the step missing prevention plate can be conveniently adjusted to adapt to the difference between different stations of a train and the threshold; besides, when a passenger accidentally steps into the gap between the train and the step missing prevention plate, the step missing prevention platecan be completely pushed back to the position under the threshold only by unscrewing the quick release bolts, so that the clamped passenger is loosened and can be disengaged easily; and after the passenger is rescued, the step missing prevention plate can be pulled out again, the bolts are screwed down, and complete resetting is achieved.
本发明公开了一种站台门可调节式防踏空板,包括:门槛、防踏空板、快拆螺栓和螺母;所述防踏空板设置在所述门槛的下方,所述门槛与所述防踏空板通过所述快拆螺栓和所述螺母连接固定;当所述快拆螺栓被拧松时,所述防踏空板能够相对于所述门槛在乘客进出方向上前后活动,以调整伸出门槛边缘的距离。本发明的站台门可调节式防踏空板,其防踏空板伸出门槛边缘的距离可以在一段范围内无级调节,以此方便分别调整适应列车在不同车站与门槛间隙的差异。另外,当乘客不慎踏入列车与防踏空板的间隙时,只要拧松快拆螺栓,就能把防踏空板完全推回门槛下方,使被夹乘客松动,可轻易脱出。将人救出后还能重新把防踏空板抽出,拧紧螺栓,完全复位。
