The invention discloses a movable extension ladder for high-altitude construction. The movable extension ladder comprises a frame, a lifting module, a support frame, a seat and a second piston cylinder. Wheels are installed at the bottom of the frame, and two parallel first sliding grooves are formed in the top face of the frame. The lifting module comprises a plurality of sets of cross assemblies and first piston cylinders. The cross assembly is composed of two main push rods arranged in parallel and two auxiliary push rods arranged in parallel, and the middle of each main push rod is hinged to the middle of one auxiliary push rod. The supporting frame is composed of a connecting rod and two rail rods, the two rail rods are fixed to the two ends of the connecting rod, and a second sliding groove and a third sliding groove are formed in the outer side and the inner side of each rail rod respectively. The tops of the two uppermost main push rods are hinged to the two ends of the connecting rod, and the tops of the two uppermost auxiliary push rods are matched with the two sliding grooves. And the seat is positioned above the support frame. According to the movable extension ladder, the height can be freely extended and retracted, the position can be freely moved, and the convenience of high-altitude construction is improved.
本发明公开了一种用于高处施工的移动伸缩梯,其包括:车架、升降模块、支撑架、座椅和第二活塞缸。车架的底部安装有车轮,车架的顶面具有两个相互平行的第一滑槽。升降模块包括多组交叉组件和第一活塞缸。交叉组件由两个相互行的主推杆与两个相互平行的副推杆构成,每个主推杆的中部与一个副推杆的中部相铰接。支撑架由连接杆与两根轨道杆组成,两根轨道杆固定于连接杆的两端,轨道杆的外侧和内侧分别有第二滑槽与第三滑槽。位于最上方的两个主推杆的顶部铰接于连接杆的两端,位于最上方的两个副推杆的顶部与两个的滑槽相适配。座椅位于支撑架的上方。本移动伸缩梯可以实现自由伸缩高度、自由移动位置,提高了高处施工的便捷性。
