The invention provides a synchronous lifting structure for building machinery and building construction. The structure comprises a base, wherein four universal wheels are installed at the bottom of the base, and a rectangular baffle is fixed on the base by bolts; a lifting mechanism is installed on the base, and the other end of the lifting mechanism is connected to a connecting mechanism; the bottom of the connecting mechanism is equipped with a driving shaft and a transmission shaft A, a labor-saving worm is installed on the driving shaft, and a turbine is installed in the middle of the transmission shaft A. A feeding structure is improved, a rocker is provided on a guardrail, the rocker and a movable pulley are connected by a wire rope, the other end of the wire rope is fixed on the guardrail, and a labor-saving arm is formed between the movable pulley and the rocker. When the wire rope is wound by rotating the rocker, the movable pulley will rise, which is convenient for the construction personnel on a support plate B to load the material alone. A ratchet is provided at one end of the handle, and the setting of the ratchet makes the feeding safer.

    本发明提供一种用于建筑机械和建筑施工同步升降结构,包括底座;底座的底部安装有四个万向轮,且底座上通过螺栓固定有矩形挡板;底座上安装有升降机构,且升降机构的另一端与连接机构相连接;连接机构的底部安装有驱动轴与传动轴A,且驱动轴上安装有省力的蜗杆,传动轴A的中间位置安装有涡轮。改进了上料结构,在护栏上设置有摇把,将摇把与动滑轮之间通过钢丝绳相连接,钢丝绳的另一端固定在护栏上,动滑轮与摇把之间形成一个省力臂,转动摇把将钢丝绳缠绕时,动滑轮会上升,方便支撑板B上的施工人员独自上料,在摇把的一端设置有棘轮,棘轮的设置使得上料更安全些。
