The invention discloses a fan block type lifting rod combination, and belongs to the field of construction tools. The fan block type lifting rod combination can manually lift and move a heavy object conveniently and quickly. The fan block type lifting rod combination comprises lifting rods, screw rods with opposite thread turning directions are transversely connected to rod bodies at the positions, away from the ends by a certain distance, of the lifting rods in a left-right opposite mode, and a round pipe, namely a nut pipe, with threads matched with the threads on the left screw rod and theright screw rod machined on the inner wall is in threaded connection with the screw rods. A section of sleeve sleeves a middle section rod body of each lifting rod in a clearance fit mode; and a balance weight and a fan block are fixedly connected to the outer side face and the inner side face of each sleeve wall, the sections of the fan blocks are in a special fan shape, and the special fan shapemeans that the circle center of a circle where the axis of the special fan shape is located is not located on the circle center of the section of the sleeve but on the horizontal line passing throughthe circle center of the section of each sleeve to the outer side. The fan block type lifting rod combination is suitable for construction places such as stone sculptures.
本发明公开了一种扇块式抬杆组合,它属于施工用具领域,它可以方便快捷地对重物进行人工托起移动。它包含抬杆,在抬杆上的距各端头一段距离处的杆体上都左右相对的横向连接有一根螺纹旋向相反的螺杆,一根在内壁上加工有与左右螺杆上的螺纹相匹配螺纹的圆管即螺母管螺纹连接到各螺杆上;在抬杆的中段杆体上都间隙配合地穿套有一段套管;在套管管壁的外侧面和内侧面都固定连接有一配重及扇块,所述扇块其断面为特殊的扇形,特殊扇形是指其弧线所在圆的圆心不在套管的断面圆心上而在通过套管断面圆心向外侧的水平线上。本设计适合于石雕等施工场所。
