Foldable ladder for railway tunnel construction
The invention relates to the technical field of railway tunnel construction equipment, in particular to a foldable ladder for railway tunnel construction, which comprises a moving seat, two rotating columns are rotatably connected to one side of the top of the moving seat, a cushion is rotatably connected between the opposite sides of the two rotating columns, a square groove is formed in the outer surface of one rotating column, and the square groove is formed in the outer surface of the other rotating column. A square groove is fixedly connected between the opposite sides of the two rotating columns, an inverted-U-shaped mounting groove is formed in the sides, connected with the connecting strip, of the two rotating columns, a supporting assembly is arranged in the inverted-U-shaped mounting groove and comprises two lead screws, the outer surfaces of the two lead screws are in threaded connection with moving blocks, and supporting rods are rotationally connected to the tops of the two moving blocks. The cushion is additionally arranged, and the supporting assembly can flexibly adjust the flatness of the cushion according to different inclination degrees of the rotating column, so that a constructor can liberate support of both legs, and the situation that the construction efficiency is reduced due to discomfort caused by leg soreness and pain is avoided.
本发明涉及铁路隧道施工设备技术领域，具体的说是一种铁路隧道施工用可折叠扶梯，包括移动座，移动座顶部的一侧转动连接有两个转动柱，两个转动柱相对的一侧之间转动连接有坐垫，其中一个转动柱的外表面开设有方形槽，两个转动柱相对的一侧之间固定连接有方形槽，两个转动柱与连接条的一侧开设有倒U型安装槽，倒U型安装槽的内部设置有支撑组件，支撑组件包括两个丝杆，两个丝杆的外表面均螺纹连接有移动块，两个移动块的顶部均转动连接有支撑杆，通过增加坐垫，且支撑组件能够根据转动柱的不同倾斜程度灵活调节坐垫的平整性，使施工人员解放双腿的支撑，避免腿部酸胀疼痛带来不适而降低施工效率。
