The invention relates to a special lifting appliance for a large steel pile and an assembly method thereof. The special lifting appliance comprises a hanging beam and a carrying pole beam. The hangingbeam is lifted and lowered by hoisting equipment. The carrying pole beam is connected with an ear plate A under the middle of the bottom surface of the hanging beam through a pulley block to realizethe lifting and sinking of a positioning tubular pile. Two groups of ear plates B are arranged on the bottom surface of the carrying pole beam. Each group of ear plates B comprises two steel plates. The ear plates B are rolled to form an arc which is consistent with the pile wall of the positioning tubular pile. A wall hole which is connected with the ear plates B is formed in the pile wall of thepositioning tubular pile. According to the special lifting appliance for the large steel pile, the effective lifting height of a crane is increased, the hoisting range is expanded, the stress direction of a steel wire rope hoisting method is changed, the deformation of the steel pile caused by an excessive horizontal force is avoided, and the special lifting appliance is suitable for hoisting steel piles of various weights.

    本发明涉及一种大型钢桩专用吊具及拼装方法,包括:挂梁和扁担梁,所述挂梁通过吊装设备实现升降,所述扁担梁通过滑轮组连接于所述挂梁底面中间下方耳板A处,以实现起吊和下沉定位管桩;所述扁担梁底面设置两组耳板B,每组耳板B为2块钢板,耳板B卷制出吻合定位管桩桩壁的弧形,所述定位管桩桩壁设置有与耳板B实现连接的壁孔。本发明增有效提升加起重机提升高度,能够扩大吊装范围,改变钢丝绳吊法的受力方向,避免钢桩受过大的水平力导致变形,适用于各种重量钢桩的吊装使用。
