The invention discloses a small-angle automatic hook retracting mechanism with an automatic positioning function, and relates to the technical field of engineering machinery. Comprising a lazy arm assembly, a third wheel assembly is fixedly installed at the position, close to the upper left side, of the lazy arm assembly, a turnover mechanism is arranged on the lower surface, corresponding to the third wheel assembly, of the lazy arm assembly, a limiting mechanism is installed on the lazy arm assembly corresponding to the turnover mechanism, and steel wire ropes are wound around the third wheel assembly and the turnover mechanism. A protection mechanism is arranged on the turnover mechanism corresponding to the steel wire rope, the steel wire rope is wound on a first pulley assembly on the lower side of the turnover mechanism, and the first pulley assembly is mounted between the upper inner wall and the lower inner wall of the lifting hook assembly; the automatic hook retracting device is compact in structure, the lifting hook and the arm body are horizontal after the hook is retracted in place, it is guaranteed that hook releasing is stable and reliable, the state is controllable after hook retracting, the accuracy of automatic hook retracting is improved, the time of automatic hook retracting is shortened, the service life of a steel wire rope is prolonged, and the safety of automatic hook retracting operation is guaranteed.

    本发明公开了一种含自动定位功能的小角度自动收钩机构,涉及工程机械技术领域;包括吊臂总成,吊臂总成靠近左上侧位置固定安装有过轮组件,过轮组件相对应的吊臂总成下表面设置有翻转机构,翻转机构相对应的吊臂总成上安装有限位机构,过轮组件与翻转机构上缠绕有钢丝绳,且钢丝绳相对应的翻转机构上设置有防护机构,钢丝绳上位于翻转机构下侧缠绕于第一滑轮组件上,第一滑轮组件安装于吊钩总成的上下内壁之间;本发明结构紧凑,实现了收钩到位后吊钩与臂体水平,保障放钩平稳可靠,收钩后状态可控,提高了自动收钩的正确率,缩短了自动收钩的时长,延迟了钢丝绳的使用寿命,保证了自动收钩作业的安全性。
