The invention discloses a folding step ladder for rail transit, which comprises a step ladder and a connecting frame for mounting the step ladder, and is characterized in that a telescopic arm for driving the step ladder to move left and right is connected below the connecting frame in a sliding manner, and driving devices for driving the step ladder to rotate are hinged to two sides of the telescopic arm; and a pedal lock for fixing the folding step ladder in a folded state is arranged at the rear end of the connecting frame. When the folding step ladder is used, the whole folding step ladder is in a suspended state and is not limited by the height of a platform, when the folding step ladder is not used, the folding step ladder is driven by the telescopic arm to retract to the bottom of a train, the bottom of the folding step ladder in a folded state is connected with the pedal in a locking and retracting mode, the two ends of the folding step ladder are provided with stress points, and the stability of the folded state is guaranteed.

    本发明公开了一种轨道交通用折叠踏梯,包括包括踏梯和用于安装踏梯的连接架,其特征在于,所述连接架下方滑动连接用于驱动踏梯左右移动的伸缩臂,伸缩臂两侧铰接用于驱动踏梯转动的驱动装置;所述连接架后端设有用于固定折叠踏梯收拢状态时的踏板锁。折叠踏梯使用时,折叠踏梯整体呈悬挂状态,不受站台高度限制,折叠踏梯在未使用时,被伸缩臂带动缩回至列车底部,收拢状态的折叠踏梯底部与踏板锁缩连接,折叠踏梯两端均有受力点,保证回收状态稳定性。
