The invention provides a stepping type lifting device used in civil construction. The stepping type lifting device comprises a vertical screw rod, a winch lifter and a material box; a shell of the winch lifter is fixed to an I-shaped frame through bolts; the vertical screw rod is inserted into an inner threaded barrel in a meshing mode through threads on the outer side of the vertical screw rod and is embedded in a main frame in a rotating mode; the bottom end of the vertical screw rod is in transmission connection with a first driving motor; the bottom side of the winch lifter is further connected with a lifting hook through winding of a steel wire rope; an outer fixing frame is fixedly connected to the exterior of the material box; and the top of the outer fixing frame is hoisted on thelifting hook through a U-shaped ring. The first driving motor is used for driving the vertical screw rod to rotate to drive the I-shaped frame and the winch lifter to move up and down, then the largest upward lifting height of the material box is adjusted, a second driving motor is used for driving transverse screw rods to rotate, and the two transverse screw rods are driven by a chain to rotate synchronously, a push plate is driven to push materials at the back end of the material box forwards, and workers can take the materials conveniently.
本发明提供一种土木建筑施工中使用的步进式升降装置,包括竖向螺杆,卷扬升降机,物料箱;所述卷扬升降机的外壳通过螺栓固定在工字型架上,所述竖向螺杆通过其外侧的螺纹啮合穿插在内螺纹筒中并转动镶嵌在主框架上,竖向螺杆的底端与第一驱动电机传动连接,所述卷扬升降机的底侧还通过钢丝绳缠绕并连接有吊钩,所述物料箱的外部固定连接有外固定框,且外固定框的顶部通过U型环吊装在吊钩上。利用第一驱动电机驱动竖向螺杆旋转,带动工字型架以及卷扬升降机上下运动,进而调整物料箱向上升起的最高高度,利用第二驱动电机驱动横向螺杆旋转,并通过链条带动两组横向螺杆同步转动,带动推板向前将物料箱后端的物料向前推动,方便工作人员的取拿。
