[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 and Figure 3 As shown, a port vessel cargo loading and unloading spreader includes a lifting frame beam 1, an outer frame plate 3, and an adjustment and installation assembly 8. Two lifting frame beams 1 are provided, and a lifting frame reinforcing beam 2 is fixed at equal intervals between the lifting frame beams 1. The outer frame plate 3 is fixedly connected to the outer side of the lifting frame beam 1. An upper adjustment hole 6 and a side adjustment hole 7 are respectively provided on the upper side of the lifting frame beam 1 and the outer side of the outer frame plate 3. A gap is provided between the outer frame plate 3 and the lifting frame beam 1 for sliding of the connecting frame 801. The lifting frame beams 1 are parallel to each other. Fixed hanging rings 4 are fixed at equal intervals on the upper side of the outer frame plate 3. A connecting piece 12 is fixed to the upper middle part of the lifting frame reinforcing beam 2. The outer frame plate 3 is close to the lifting frame reinforcing beam. A reinforcing strip 5 is fixed on one side of beam 2, and the reinforcing strip 5 is fixedly connected to the lifting frame reinforcement beam 2. The number of reinforcing strips 5 and the lifting frame reinforcement beam 2 are the same, and the reinforcing strip 5 has a triangular structure. The lifting frame crossbeam 1 and the lifting frame reinforcement beam 2 constitute the lifting frame structure. The outer frame plate 3 can protect the outside of the connecting frame 801 and the lifting frame crossbeam 1 from collision. At the same time, the reinforcing strip 5 fixedly connected to the lifting frame reinforcement beam 2 on one side of the outer frame plate 3 can enhance the structural strength of the lifting frame. The setting of the fixed hanging ring 4 or the connecting piece 12 facilitates the connection and installation between the lifting frame and the lifting device. The upper adjustment hole 6 and the side adjustment hole 7 at different positions are used to connect the connecting frame 801 with the corresponding bolts.

[0022] like Figure 2 and Figure 3As shown, an adjustment mounting assembly 8 is installed on the outside of the suspension frame beam 1. The adjustment mounting assembly 8 includes a connecting frame 801 and a threaded groove 802. The connecting frame 801 is a rectangular frame and is slidably connected to the suspension frame beam 1. Threaded grooves 802 are respectively provided on the upper middle part and the outer middle part of the connecting frame 801. A sling 10 is connected to the bottom of the connecting frame 801, and a hook 11 is installed on the lower side of the sling 10. The adjustment mounting assembly 8 also includes an upper locking bolt 803. The upper threaded groove 802 of the connecting frame 801 passes through the upper locking bolt 803, and the upper locking bolt 803 also passes through the upper adjustment hole 6 of the suspension frame beam 1. The adjustment mounting assembly 8 also includes a connecting rod 804. There are four sets of connecting frames 801, with two connecting frames 801 in each set. A connecting rod 804 is fixed between the connecting frames 801. A side locking bolt 9 passes through the side adjustment hole 7 of the outer frame plate 3, and the other end of the side locking bolt 9 passes through the threaded groove 802 on the side of the connecting frame 801. The rectangular connecting frame 801 can slide on the outside of the lifting frame beam 1 to flexibly adjust the position of the connecting frame 801 and the sling 10 and hook 11 connected to its lower side. It is suitable for lifting objects with different centers of gravity and different lifting points. The upper locking bolt 803 facilitates the connection between the connecting frame 801 and the lifting frame beam 1. The universal side locking bolt 9 facilitates the connection between the outer frame plate 3 and the connecting frame 801. The multi-directional connection method makes the connecting frame 801 fixed and stable. A connecting rod 804 is fixed between each pair of connecting frames 801 to make the positions of each pair of connecting frames 801 consistent.

[0023] In summary, as Figures 1-3 As shown, this port ship cargo loading and unloading spreader, in use, consists of a frame beam 1 and a reinforcing beam 2 forming the spreader's frame structure. An outer frame plate 3 provides collision protection for the connecting frame 801 and the outer side of the frame beam 1. Simultaneously, a reinforcing strip 5, fixedly connected to the reinforcing beam 2 on one side of the outer frame plate 3, enhances the structural strength of the spreader frame. Firstly, the position of the rectangular connecting frame 801 can be adjusted by sliding it on the outer side of the frame beam 1. At this time, a connecting rod 804 is fixed between each pair of connecting frames 801 to ensure that the positions of each pair of connecting frames 801 are consistent, facilitating flexible adjustment of the connecting frames 801. Position the sling 10 and hook 11 connected to the lower side of the frame 1. Then, the upper locking bolt 803 facilitates the connection between the connecting frame 801 and the lifting frame beam 1. The universal side locking bolt 9 facilitates the connection between the outer frame plate 3 and the connecting frame 801. The multi-directional connection method makes the connecting frame 801 fixed and stable, so that it can be used for lifting objects with different centers of gravity and different lifting points. Then, the setting of the fixed hanging ring 4 or the connecting piece 12 facilitates the connection and installation between the lifting frame and the lifting device. Finally, the object to be lifted can be set at the hook 11 below. This completes the process of using the lifting equipment for loading and unloading cargo on ships in the port.
