The invention discloses an unhooking lifting appliance for lifting a cross beam. The unhooking lifting appliance comprises a plate body, a lifting rope, a turntable, a torsional spring, a winding disc, a pull rope and a synchronous rotating mechanism, wherein the turntable is provided with a pawl, a driving belt wheel and two rope passing holes, and the two rope passing holes are symmetrically arranged relative to the center of the turntable; the winding disc is provided with a rope winding disc and a ratchet wheel, and the ratchet wheel is matched with the pawl. The middle part of the pull rope is wound on the winding disc, and a hook is fixed at the end part of the pull rope; the synchronous rotating mechanism comprises a synchronous belt and a rotating hook, a driven belt wheel and a hook plate are arranged on the rotating hook, and the driven belt wheel is connected with the driving belt wheel through the synchronous belt. The rotating disc, the winding disc and the pull rope form an automatic centering mechanism, the two hooks are hooked at the two ends of the cross beam respectively, the lifting appliance can automatically move to the center of the cross beam, the lifting center coincides with the gravity center of the cross beam, and the problem that the cross beam is unbalanced during lifting is solved. According to the lifting appliance, time and labor are saved, hooking and unhooking of the cross beam are automatically achieved, and unsafe factors in an existing lifting mode are eliminated.

    一种用于横梁吊装的可脱钩吊具,包括板体、吊绳、转盘、扭簧、收卷盘、拉绳和同步旋转机构。其中,转盘设有棘爪、主动带轮和两个过绳孔,两个过绳孔关于转盘的中心对称设置;收卷盘设有卷绳盘和棘轮,棘轮与棘爪配合;拉绳的中部缠绕在收卷盘上,在拉绳的端头部固定有挂钩;同步旋转机构包括同步带和旋转钩,在旋转钩上设有从动带轮和钩板,从动带轮通过同步带与主动带轮连接。转盘、收卷盘和拉绳构成了自动对中机构,将两个挂钩分别钩在横梁的两端,可使本吊具自动移动到横梁的中心部位,使吊心与横梁的重心重合,解决了横梁在起吊时的不平衡问题。本吊具省时省力,自动实现了对横梁的钩挂和脱钩,排除了现有吊装方式中的不安全因素。
