In addition, the lifting machinery is equipped with mostly one type of hook, either a single hook or a double hook, and the later type replacement is relatively cumbersome and time-consuming. Summary of the invention

[0005] The present invention relates to a lifting machinery for port logistics management, which solves the problem that in the application process of existing lifting machinery for port logistics, the lifting hooks used for lifting are usually connected and fixed with bolts to ensure the safety of use. When the hooks are severely worn or cracked, the disassembly and replacement are cumbersome and time-consuming, which can easily affect the progress of cargo shipment. In addition, the lifting hooks equipped on the lifting machinery are mostly of one kind, either a single hook or a double hook, and the replacement of the types at a later stage is relatively cumbersome and time-consuming.

[0006] In a first aspect of the present disclosure, a lifting machinery for port logistics management is provided, which specifically includes: a main fishing body; a movable pulley is installed on the top of the main fishing body, and the movable pulley is connected to the crane through a steel wire rope; a movable connecting piece is installed on the bottom of the main fishing body, and movable pull rings are installed at both ends of the movable connecting piece, and a tension spring is connected to the outside of the movable pull ring; a force-bearing vertical connecting shaft is connected to the bottom of the movable connecting piece, the force-bearing vertical connecting shaft is rotatably connected to the movable connecting piece, and a lifting hook is connected to the bottom of the force-bearing vertical connecting shaft; a movable locking sleeve is sleeved on the outside of the force-bearing vertical connecting shaft, and the movable locking sleeve is connected to the lifting hook; an elastic limiting clamp is connected to the outside of the force-bearing vertical connecting shaft, and the elastic limiting clamp is connected to the movable locking sleeve.

[0007] Furthermore, the lifting hook is divided into two types: a single hook and a double hook. A slot is provided on the top of the lifting hook, and the bottom end of the load-bearing vertical connecting shaft is inserted into the slot.

The spring has the effect of resetting the movable locking sleeve. When the lifting hook and the stressed vertical connecting shaft are clamped together, the stress block moves to the innermost end of the stress groove, and the movable locking sleeve moves downward under the influence of the spring thrust, so that the plug block is inserted into the stress groove. The cooperation between the plug block and the stress groove has the effect of limiting the lifting hook.

[0017] In addition, when the movable locking sleeve moves downward to the bottom, the outer connecting hole and the inner connecting groove are in a connected state, and the elastic limiting clamp is connected to the outer connecting hole and the inner connecting groove. The elastic limiting clamp is used to lock and fix the movable locking sleeve, further ensuring the firmness of the connection between the lifting hook and the stressed vertical connecting shaft; when the lifting hook needs to be replaced, first separate the elastic limiting clamp from the outer connecting hole and the inner connecting groove, and then move the movable locking sleeve upward to separate the plug from the stressed groove, and then rotate the lifting hook. The lifting hook is separated from the stressed vertical connecting shaft by itself under the influence of gravity, and the lifting hook replacement operation can be completed. The operation is simple and quick.

[0018] In addition, when the lifting hook falls to a height slightly higher than the required height, there is no need to communicate with the crane operator through the intercom. The lifting hook can be directly pulled down manually, and the tension spring is stretched, so that the lifting hook moves downward, lowering the height of the lifting hook and connecting it to the wire rope for lifting logistics goods, better meeting the actual needs of cargo shipping.
