The invention discloses a self-unhooking hoisting tool for a prefabricated component and a hoisting method. The hoisting tool comprises a balance bar and a cross-core bearing bar; rope fixing ends used for limiting hoisting steel chains are arranged on the two sides of the balance bar; one end of the cross-core bearing bar is provided with an annular groove matched with a safety valve; a baffle with the orthographic projection completely covering the cross-core bearing bar is fixed to the other end of the cross-core bearing bar; the whole safety valve is in a sheet shape; a through hole I anda through hole II which are connected with each other are formed in the safety valve; the connecting part of the through hole I and the through hole II can enable the cross-core bearing rod to freelyenter the through hole I and the through hole II; the outer edge of the through hole I is matched with the annular groove; the orthographic projection area of the through hole II completely covers theorthographic projection area of the cross-core bearing bar and is larger than the orthographic projection area of the cross-core bearing bar; a thickening sheet is arranged around the outer edge of the through hole II; and after the prefabricated component is hoisted, the safety valve is rotated to complete the self-unhooking operation. The hoisting tool and the hoisting method have the advantages that the structure is simple, the integral structure rigidity is high, and the reliability is good; and self-unhooking can be finished on the ground, the efficiency is high, potential safety hazardsare avoided, and the application prospect is good.

    本发明公开了一种预制构件自脱钩起吊工装及吊装方法,包括平衡杆和穿心承重杆;平衡杆两侧均设有用于对吊装钢链进行限位的绳索固定端;穿心承重杆一端设有与安全阀匹配的环形槽,另一端固定有正投影完全覆盖穿心承重杆的挡板;安全阀整体呈片状,其上开有彼此连接的通孔I和通孔II,通孔I和通孔II的连接部能够使得穿心承重杆自由进入通孔I和通孔II内,通孔I的外缘与环形槽匹配,通孔II的正投影面积完全覆盖且大于穿心承重杆正投影面积,安全阀围绕通孔II外缘设有加厚片;在完成预制构件吊装后,转动安全阀即完成自脱钩操作。本发明的结构简单,整体结构刚性高,可靠性好;在地面即可完成自脱钩,效率高,无安全隐患,应用前景好。
