The invention discloses a crane coupler combined type anti-drop device which comprises a lifting hook. A steel wire rope is fixedly arranged at the upper end of the lifting hook, the upper end of the steel wire rope is connected with a lifting arm of a crane, an anti-drop mechanism for carrying out anti-drop blocking on the lifting hook is arranged at the position, close to the upper end, of the lifting hook, and the upper end of the lifting hook is rotatably hung on a hanging plate. The lifting hook and the hanging plate are controllably and rotatably connected, an inverted-U-shaped fixing frame is fixedly arranged at the upper end of the hanging plate, and the upper end of the fixing frame is fixedly connected with the steel wire rope through a connecting sleeve. When a heavy object is lifted, the lifting hook is hung on the heavy object, at the moment, the opening of the lifting hook is blocked through the anti-drop mechanism, so that anti-drop protection is achieved, and the device has a better anti-drop effect; and meanwhile, through rotatable control between the lifting hook and the hanging plate, when the heavy object is hung, the lifting hook can be aligned with the heavy object by controlling the direction of the lifting hook, and hanging is more convenient.

    本发明公开了一种吊车车钩组合式防脱装置,包括吊钩,吊钩的上端固定设置有钢丝绳,且钢丝绳的上端与吊车的吊臂连接,吊钩靠近上端位置设置有对吊钩进行防脱阻拦的防脱机构,且吊钩的上端可转动挂在挂板上,吊钩与挂板之间可控制转动连接,挂板的上端固定设置有倒U型的固定架,且固定架的上端通过连接套与钢丝绳固定连接,在对重物进行起吊时,通过吊钩挂在重物上,此时通过防脱机构多吊钩开口处进行封堵则实现防脱保护,具有较好防脱钩效果,同时通过吊钩与挂板之间的可转动控制能够在对重物进行吊挂时,通过控制吊钩的方向使其对准重物,吊挂更加的方便。
