The invention relates to a large-diameter concrete pipe lifting device which comprises a rectangular top plate. Vertical rods perpendicular to the top plate are welded to the portions, located on fourcorners of the top plate, of the top plate bottom face correspondingly. Two clamping rods are arranged between every two vertical rods of the two opposite sides of the top plate correspondingly, wherein an upper shaft cylinder is welded between the upper ends of the two clamping rods, and a lower shaft cylinder is welded between the middle portions of the two clamping rods. The upper half portionof each clamping rod is of a smooth and straight structure, and the lower portion of each clamping rod is of an arc-shaped structure bent toward the opposite sides of the top plate. A penetrating clamping rod and a rotating shaft of the corresponding lower shaft cylinder are inserted between the lower ends of the two vertical rods of each side of the top plate in a penetrating manner. A penetrating clamping rod and a plug pin inserted into the corresponding upper shaft cylinder are movably inserted to the upper ends of every two vertical rods in a penetrating manner correspondingly. Accordingto the large-diameter concrete pipe lifting device, the clamping rods on the two sides form a pincer-like structure, a concrete pipe can be held or clamped to be lifted, after the concrete pipe is lifted in place, the clamping rods on the two sides are separated, then the concrete pipe can be unloaded, construction is convenient and rapid, and damage to the concrete pipe is avoided.

    本发明涉及一种大直径混凝土管吊具,包括一矩形的顶板,顶板底面位于顶板4个角处分别焊接一与顶板垂直的竖杆,顶板两个相对侧的每两根竖杆之间分别设置两根夹杆,两夹杆上端之间焊接一上轴筒,两夹杆中部之间焊接一下轴筒,每个夹杆的上半部为顺直结构,下半部为向顶板相对侧弯曲的弧形结构;顶板每侧的两竖杆下端之间穿插一贯穿夹杆及下轴筒的转轴,两竖杆上端分别活动穿插一贯穿夹杆并插入上轴筒内的插销。本发明两侧的夹杆形成钳形结构,可抱住或夹住混凝土管起吊,起吊到位后将两侧夹杆分开即可卸载混凝土管,施工方便、快捷,且不会对混凝土管造成损坏。
