The invention discloses a variable-span passing step device. The variable-span passing step device comprises an outer frame, a middle frame and an inner frame. Telescopic legs are arranged on the outer frame, and the lengths of the telescopic legs can be adjusted according to the height difference of the steps, so that the outer frame is kept horizontal and stable all the time. The inner frame is provided with telescopic retreating parts, and the lengths of the telescopic retreating parts can be adjusted according to the height difference of the steps, so that the inner frame is kept horizontal and stable all the time. The frames can relatively move in the horizontal direction and the vertical direction. The device has the following beneficial effects: (1), the gravity center of the system is ensured to be always within the fulcrum coverage range of the bearing bracket of the device, and the safety of a user is ensured; and (2), different step heights and widths are adapted.

    本发明公开了一种可变跨度通行台阶装置,包括外框架,中间框架和内框架。在外框架上,有伸缩腿,伸缩腿的长度可以根据台阶的高度差进行调节,从而使外框架始终保持水平平稳。在内框架上,有伸缩退,伸缩退的长度可以根据台阶的高度差进行调节,从而使内框架始终保持水平平稳。框架之间可以水平和垂直向相对运动。本发明的有益效果是:(1)确保了系统重心始终在装置承重支架支点覆盖范围之内,确保了使用者的安全。(2)适应不同的台阶高度与宽度。
