The invention relates to the field of tunnel construction, and particularly discloses a movable operation platform for subway tunnel construction, which comprises an upper bedplate and a lower bedplate, a lifting mechanism is connected between the upper bedplate and the lower bedplate, and the lifting mechanism comprises a bearing rod, a lifting rod and a rocker, and the rocker penetrates through the interior of the bearing rod and is provided with a rotating gear through a rotating shaft, an adjusting rack is installed on the inner side wall of the reserved groove, limiting clamping holes are formed in the reserved groove in an array mode, and a limiting plug pin is installed on one side, penetrating through the interior of the rotating shaft, of the rocker. When torsion is applied to a rocker, a rotating gear at the end of a rotating shaft and an adjusting rack in a reserved groove are made to rotate in a meshed mode, and therefore lifting adjustment of the whole lifting rod in a bearing rod can be controlled, and a limiting plug pin penetrating through the interior of the rotating shaft is pushed to the position close to the inner side of the reserved groove; after the bearing rod and the lifting rod are installed through the limiting clamping holes in different positions, the overall position of the bearing rod and the lifting rod can be limited.

    本发明涉及隧道施工领域,具体公开了一种地铁隧道施工用可移动作业平台,包括上台板和下台板,所述上台板和下台板之间连接有升降机构,所述升降机构包括:承重杆、升降杆和摇杆,所述摇杆穿过所述承重杆的内部通过转轴安装有转动齿轮,所述预留槽的内侧壁安装有调节齿条,所述预留槽的内部阵列设置有限位卡孔,所述摇杆的一侧贯穿所述转轴的内部安装有限位插销。对摇杆施加扭力时,会使得转轴端部的转动齿轮和预留槽内部的调节齿条进行啮合转动,从而可以实现控制升降杆整体在承重杆的内部的升降调节,将穿过转轴内部的限位插销向靠近预留槽的内侧进行推动,和不同位置的限位卡孔进行安装后,则能够将承重杆和升降杆的整体位置进行限定。
