The invention discloses a crane with a precise automatic positioning device, which relates to the technical field of crane positioning, and is characterized in that the top end of a lifting hook is fixedly connected with a connecting plate, the side end of the lifting hook is fixedly connected with a locking seat, the bottom of the lifting hook is provided with a sliding chute, and two ends of the top of the lifting hook are respectively provided with a rotating hole; the positioning assembly is sleeved with the rotating hole and rotationally connected with the inner wall of the top of the lifting hook, the side end of the positioning assembly is connected with the locking base in a matched mode, the driving assembly is sleeved with the sliding groove and slidably connected with the inner wall of the sliding groove, and the locking assembly is fixedly connected to the side end of the locking base and connected with the positioning assembly in a matched mode; when the steel wire rope is straightened and starts to pull the lifting hook, the positioning assembly blocks the opening part of the lifting hook, and when the positioning assembly is in contact with the locking seat, the locking assembly automatically locks the positioning assembly, so that the phenomenon that a heavy object is unhooked from the lifting hook when the heavy object is continuously pulled up due to misoperation of a worker is avoided.

    本发明公开了一种具有精准自动定位装置的起重机,涉及起重机定位技术领域,包括:吊钩顶端固定连接有连接板,吊钩侧端固定连接有锁紧座,吊钩底部开设有滑槽,吊钩顶部两端分别开设有旋转孔,所述连接板顶端固定连接有钢丝绳,定位组件套设在旋转孔内且与吊钩顶部内壁旋转连接,定位组件侧端与锁紧座配合连接,驱动组件套设在滑槽内且与滑槽内壁滑动连接,锁紧组件固定连接在锁紧座侧端,锁紧组件与定位组件配合连接;当钢丝绳拉直开始拉动吊钩时,定位组件对吊钩开口部分进行封堵,当定位组件和锁紧座接触时,锁紧组件对定位组件进行自动锁死,避免工作人员误操作导致重物继续拉起时,重物从吊钩发生脱钩的现象。
