The invention discloses an automatic unhooking and hooking device for a ton bag lifting hook. The automatic unhooking and hooking device comprises a supporting plate, at least three movable carrying positions are arranged on the supporting plate, unhooking devices matched with the movable carrying positions are arranged on the supporting plate, and the unhooking devices overturn on the movable carrying positions under the action of gravity; a tension mechanism acting on the detacher is arranged at the bottom of the supporting plate, the detacher completes overturning under the action of the tension mechanism, and the detacher automatically resets to the initial state and completes unhooking at the same time after the action of the tension mechanism is removed. On the basis of gravity overturning unhooking, the tension mechanism is additionally arranged, the hook can be pulled and overturned to a certain angle after unhooking is completed, the hook can automatically pull up a ton bag hanging ring, then tension on the hook is canceled, the hook can automatically overturn to drive the hanging ring to automatically fall off after completing hoisting operation and falling off, and the safety of the ton bag hanging ring is improved. A user does not need to manually hook hooks one by one before lifting, the operation process is reduced, and the work efficiency of rising and falling of the ton bags can be improved.

    本发明公开了一种吨包吊钩自动脱钩挂钩装置,包括支撑板,支撑板上设置有不少于三个的活动载位,在支撑板上设置有与活动载位相匹配的脱钩器,脱钩器受重力作用在活动载位上进行翻转;在支撑板的底部设置有作用于脱钩器的拉力机构,脱钩器在拉力机构的作用下完成翻转,脱钩器在拉力机构撤销作用后自动复位至初始状态且同时完成脱钩。本发明在重力翻转脱钩的基础上,增设了拉力机构,能够在脱钩完成后,将挂钩拉动翻转至一定角度,使挂钩能够将吨袋吊环自动拉起,随后取消对吊钩的拉力,能够使挂钩在完成吊起作业落下后自动翻转带动吊环自动脱落,无需使用者在吊起前需要手动逐个挂钩的操作,减少操作流程,能够提高吨袋起落的工作效率。
