The invention relates to the technical field of lifting hooks, in particular to a lifting hook capable of effectively limiting air torsion and swing of a lifted object. A through groove is formed in the surface of the fixed end, a third roller is arranged on the inner wall of the through groove, a second roller is arranged on the upper surface of the fixed end, a first connecting rod and a second connecting rod are fixed to the inner side surface of the fixed end, and the outer surface of the first connecting rod is sleeved with a first roller. The lifting device has the beneficial effects that the three groups of lifting ropes are led out through the hollow cargo boom, pulling force steering and transmission dispersion are achieved through the roller group arranged at the fixed end, the three groups of lifting ropes are effectively distributed to a larger platform at the fixed end, the stability of a triangle is utilized, and the stability of the lifting device is improved. The swinging problem of the lifted object in the air is effectively relieved; as the distance between each group of lifting ropes is increased, the rotational inertia of articles around the lifting ropes is increased and the articles are difficult to rotate.

    本发明涉及吊钩技术领域,具体为一种可有效限制被吊物品空中扭转及摆动的吊钩;包括固定端表面开设有通槽,通槽内壁设有第三滚筒,固定端上表面设有第二滚筒,固定端内侧表面固定有第一连接杆和第二连接杆,第一连接杆外表面套设有第一滚筒,活动端下表面固定有吊钩,活动端上表面设有第三滚筒,第三滚筒弧形表面设有第一吊绳、第二吊绳和第三吊绳,有益效果为:三组吊绳经由中空的起重臂引出,通过固定端上设有的滚筒组,实现拉力转向与传动分散,三组吊绳在固定端被有效分配至更大平台上,利用三角形的稳定性,有效缓解被吊物品在空中的摆动问题;每组吊绳之间距离增大,物品绕吊绳转动惯量变大,难以旋转。
