The invention discloses a crane automatic unhooking device. The crane automatic unhooking device comprises a mounting plate and a hook handle, a hanging rod is fixedly mounted in the middle of the upper end of the mounting plate, two mounting frames which are symmetrical front and back are fixedly mounted at the lower end of the mounting plate, each mounting frame is of a U-shaped structure, an arc-shaped plate and a transverse plate are sequentially and fixedly mounted in each mounting frame from top to bottom, the mounting plate, the mounting frames, the arc-shaped plates and the transverse plates are of an integrated structure together, arc grooves penetrating front and back are formed in the middle right portions of the front ends of the arc-shaped plates, the hook handle is located between the two mounting frames, a hook head is fixedly mounted at the lower end of the hook handle, a gravity self-locking mechanism is arranged on the lower side of the inner wall of the hook head, and the hook handle is of a structure with the upper portion wider than the lower portion. According to the crane automatic unhooking device, the unhooking prevention function is achieved by arranging the gravity self-locking mechanism, self-locking is achieved through the gravity of a hoisted heavy object, safety and reliability are achieved, the automatic unhooking function is achieved by means of gravity in cooperation with the gravity self-locking mechanism, the structure is compact, and safety is high.

    本发明公开了一种起重机自动脱钩装置,包括安装板和钩柄,所述安装板上端中部固定安装有吊杆,所述安装板的下端固定安装有两个前后对称的安装架,所述安装架呈U形结构,所述安装架内部从上到下依次固定安装有弧形板和横板,所述安装板、安装架、弧形板和横板共同呈一体结构,所述弧形板前端中右部开有前后贯通的弧槽,所述钩柄位于两个安装架之间,所述钩柄下端固定安装有钩头,所述钩头内壁下侧设置有重力自锁机构,所述钩柄呈上宽下窄结构。本发明的一种起重机自动脱钩装置,通过设置重力自锁机构实现防止脱钩功能,利用被吊重物的自身重力实现自锁,安全可靠,通过利用重力配合重力自锁机构实现自动脱钩功能,结构紧凑,安全性强。
