The invention relates to the technical field of lifting hooks, in particular to a lifting hook for large hoisting equipment, which comprises a pulley box and two fixing plates arranged at the bottom of the pulley box, supporting columns are mounted in the fixing plates in a penetrating manner, a supporting plate is fixedly mounted between the two supporting columns, and a hook is mounted in the supporting plate in a penetrating manner. The conversion assembly is arranged at the top of the hook; the rotating mechanism and the lifting assembly are arranged at the top of the supporting plate; by adopting the design of the conversion assembly, the rotating mechanism and the lifting assembly, when the hook is used for bearing, cambered surface teeth at the bottom of the supporting plate enter the inner side of a cambered surface groove to prevent the hook from rotating horizontally, and when the hook is in a no-load state, a spring drives an inner groove ring to move upwards through a rope, so that right-angle teeth at the top of a supporting seat are in contact with a straight toothed plate; the motor is started to drive the straight toothed plate to rotate, the straight toothed plate is meshed with the right-angle teeth and drives the supporting base to rotate, and then the supporting base drives the hook to rotate, so that the hook freely rotates in the no-load state and is automatically locked in the bearing state.

    本发明涉及吊钩技术领域,具体的说是一种大型起重设备用吊钩,包括滑轮箱和设置在其底部的两个固定板,所述固定板的内部贯穿安装有支柱,两个支柱之间固定安装有支撑板,支撑板的内部贯穿安装有挂钩,还包括挂钩顶部设置的转换组件,以及支撑板顶部设置的旋转机构和提升组件;本发明通过采用了转换组件、旋转机构和提升组件的设计,当挂钩承载时,支撑板底部的弧面齿进入到弧面槽的内侧,防止挂钩水平旋转,当挂钩在空载状态下,弹簧通过绳缆带动内槽环向上移动,使支撑座顶部的直角齿与直齿板接触,启动电机带动直齿板旋转,直齿板与直角齿啮合并带动支撑座旋转,进而通过支撑座带动挂钩旋转,使挂钩空载时自由旋转、承载时自动锁死。
