The invention discloses a wedge block type lifting rod combination, and belongs to the field of construction tools. The wedge block type lifting rod combination can manually lift and move a heavy object conveniently and quickly. The wedge block type lifting rod combination comprises a pair of long circular lifting rods and a pair of short circular clamping rods, the pair of lifting rods are parallel and horizontal, the pair of clamping rods are further parallel and horizontal, and the clamping rods are located below the lifting rods and the clamping rods and the lifting rods are both in the longitudinal direction; a screw rod with opposite thread turning directions is oppositely connected between the same end of each clamping rod, and a circular pipe, namely a nut pipe, being provided withthreads matched with the threads on the screw rods on the sides, of the inner wall, is in threaded connection with each screw rod; a wedge block with the thin upper part and the thick lower part is arranged on the inner side of the middle of each clamping rod, an elastic hook with a downward opening is arranged on the outer side of each wedge block, the wedge blocks are hung on the clamping rodsthrough hooks, and lower openings of the hooks can bind the clamping rods and prevent the clamping rods from falling off at will so that the lap joint assemblies are combined into a whole; and the lifting rods are fixedly connected to the upper parts of the wedge blocks in a penetrating mode. The wedge block type lifting rod combination is suitable for construction places such as stone sculptures.
本发明公开了一种楔块式抬杆组合,它属于施工用具领域,它可以方便快捷的对重物进行人工托起移动。它包含一对较长的圆形抬杆,一对较短的圆形夹杆,所述抬杆一对并列且水平,夹杆一对也并列且水平,夹杆处于抬杆的正下方且都呈纵向;在各夹杆的同一端之间都相对的连接有一根螺纹旋向相反的螺杆,一根在内壁上加工有与各侧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;在各夹杆的中间内侧都装置有一上薄下厚的楔块,楔块的外侧有一开口朝下的弹性挂钩,楔块通过挂钩挂到夹杆上,挂钩的下开口能够束住夹杆不使其随意脱落以使得各搭连组件组合为一体;在楔块上方固定穿连着抬杆。本设计适合于石雕等施工场所。
