The invention belongs to the technical field of cranes, and particularly relates to a self-locking lifting hook which comprises a hook body, a pulley is rotationally connected into the hook body, and a steel wire rope is arranged on the outer wall of the pulley; one end of the steel wire rope is fixedly connected with a buckle, the other end of the steel wire rope is fixedly connected with a balancing weight, the interior of the balancing weight is rotationally connected with one end of a limiting rod, a first sliding groove is formed in the hook body, the outer wall of the other end of the limiting rod is slidably connected to the inner wall of the first sliding groove, and the outer wall of the buckle is fixedly connected with a limiting plate. A second sliding groove is formed in the hook body in a penetrating mode, the outer wall of the limiting plate is slidably connected into the second sliding groove, and a fixing assembly is arranged on the upper surface of the hook body. The problem that in the prior art, in the actual using process, it is not considered that in the prior art, in the actual using process, the arrangement of a locking plate is likely to hinder a hoisted object, and therefore the hoisted object is not convenient to hook in is solved.
本发明属于起重机技术领域,尤其涉及一种自锁式起重吊钩,包括钩身,钩身的内部转动连接有滑轮,滑轮的外壁设置有钢丝绳;钢丝绳的一端固定连接有卡扣,钢丝绳的另一端固定连接有配重块,配重块的内部与限位杆的一端转动连接,钩身的内部开设有第一滑槽,限位杆的另一端的外壁滑动连接在所述第一滑槽的内壁,卡扣的外壁固定连接有限位板,钩身的内部贯穿开设有第二滑槽,限位板的外壁滑动连接在所述第二滑槽的内部,钩身的上表面设置有固定组件。本发明解决了现有技术中没有考虑到在实际使用过程中,锁板的设置容易对吊运物体形成阻碍,从而存在不便于钩入被吊物体的问题。
