The invention discloses a stepping ladder climbing machine upstairs and downstairs safety device which comprises a unit safety mechanism, the unit safety mechanism comprises a step side face abutting mechanism, a horizontal plane abutting mechanism, an upstairs travel switch, a downstairs travel switch and a support, and the upstairs travel switch and the downstairs travel switch are both installed on the support. The step side face abutting mechanism and the horizontal face abutting mechanism are both installed on the support in a swinging mode, the step side face abutting mechanism can swing to trigger the upstairs travel switch, and the horizontal face abutting mechanism can trigger the downstairs travel switch. The stepping ladder climbing machine can be used for the stepping ladder climbing machine, the step side face abutting mechanism can abut against the side face of a step needing to climb so as to trigger the upstairs travel switch, the horizontal face abutting mechanism can be suspended so as to trigger the downstairs travel switch, and therefore the stepping ladder climbing machine can be timely triggered to work when needed; and the working reliability of the stepping ladder climbing machine is ensured.
本发明公开了一种步进爬梯机上下楼保险装置,包括单元保险机构,单元保险机构包括阶梯侧面抵接机构、水平面抵接机构、上楼行程开关、下楼行程开关和支架,上楼行程开关和下楼行程开关均安装在支架上,阶梯侧面抵接机构和水平面抵接机构均可摆动地安装在支架上,阶梯侧面抵接机构能摆动触发上楼行程开关,水平面抵接机构能触发下楼行程开关。本发明能用于步进爬梯机上,而阶梯侧面抵接机构能与需要爬升的阶梯的侧面相抵接以此触发上楼行程开关,水平面抵接机构会发生悬空而以此触发下楼行程开关,由此,本发明在需要时能适时触发步进爬梯机的工作,保证步进爬梯机的工作可靠性。
