The invention discloses an automatic opening and closing type anti-falling lifting hook device used for hoisting machinery, and relates to the technical field of lifting hooks. The problem that the optimal design of an anti-release structure of a hook connecting component of an existing anti-falling lifting hook is not ideal enough, consequently, the lifting hook is prone to being disassembled inair during splicing and use, and a hoisted object has a relatively large hidden danger of shaking and falling are solved. The automatic opening and closing type anti-falling lifting hook device used for the hoisting machinery comprises hook bodies, each hook body comprises a rail strip, a positioning frame, positioning short shafts and a blocking frame, and the two hook bodies are spliced to forma double-lug lifting hook. The two corresponding positioning short shafts are symmetrically welded to the top end section of each of the two hook bodies, and the two positioning short shafts on the left side are each provided with a hook plate in a sleeved and rotating manner. Steel wire lifting ropes penetrate through semicircular clamping plates, the semicircular clamping plates can drive sliding frames and ejector blocks to slide upwards through the up-lifting force of the steel wire lifting ropes, and therefore the trouble that the ejector blocks are ejected and pushed to slide upwards through manual force is omitted.
本发明公开了一种用于起重机械的自动启闭式防脱吊钩装置,涉及吊钩技术领域,解决了现有的防脱吊钩,钩挂连接部件的防脱扣结构优化设计的不够理想,造成在吊钩拼接使用时易在空中解体致使吊装物件具有较大的摇晃坠落隐患的问题。一种用于起重机械的自动启闭式防脱吊钩装置,包括挂钩本体,所述挂钩本体包括轨道条,定位框,定位短轴和挡框,两处所述挂钩本体拼接组成了一处双耳吊钩;两处所述挂钩本体的顶端段均对称焊接有两处定位短轴,其中左侧两处定位短轴上均套转安装有一处钩板。本发明钢丝吊绳穿引通过半圆卡板,半圆卡板可利用钢丝吊绳的上提拉力驱使滑动架以及顶块上滑,这省去人工出力顶推上滑顶块的麻烦。
