Detailed implementation manners

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the exemplified embodiments are not intended to limit the present utility model.

[0022] Embodiment 1

[0023] Referring to Figures 1 - 3 As shown, the present utility model discloses a novel structure of a base of a discharging arm, including: at least three first enclosing plates 1, at least two second enclosing plates 2 and a panel 3; at least three of the first enclosing plates 1 are circumferentially arranged, and a second enclosing plate 2 is arranged between any two adjacent first enclosing plates 1. The first enclosing plates 1 and the second enclosing plates 2 are flush in height, and the first enclosing plates 1 and the second enclosing plates 2 are connected to each other to form a polygonal enclosure structure; the panel 3 is arranged on the tops of the first enclosing plates 1 and the second enclosing plates 2, and the panel 3 is perpendicular to the first enclosing plates 1 and the second enclosing plates 2; drainage ports 11 are arranged at the bottoms of the plurality of first enclosing plates 1.

[0024] Specifically, the structure of the base of the discharging arm in the present utility model forms the main body of the base of the discharging arm by combining a plurality of first enclosing plates 1 and a plurality of second enclosing plates 2. The panel 3 is arranged on the tops of the first enclosing plates 1 and the second enclosing plates 2 and is used to form a horizontal plane for installing the entire discharging arm. The polygonal enclosure structure formed by the first enclosing plates 1 and the second enclosing plates 2, during the actual assembly process, first weld the polygonal enclosure structure to the deck of the ship, then embed the slewing mechanism in the enclosure structure, and finally weld between the slewing mechanism and the panel 3. During the assembly process, only the flatness of the upper surface of the panel 3 needs to be ensured, which greatly reduces the assembly difficulty. Secondly, drainage ports 11 are formed on the side walls of the first enclosing plates 1, so that the accumulated water inside the base of the discharging arm can be drained in time, avoiding the corrosion of the base by the accumulated water inside the base of the discharging arm and extending the service life of the entire base of the discharging arm.

[0025] The structure of the base of the discharging arm in the present utility model is simple, and during the assembly process, it is assembled with the slewing mechanism by direct welding, which greatly reduces the assembly difficulty. Secondly, through the drainage ports 11 at the bottoms of the first enclosing plates 1, the accumulated water inside the base of the discharging arm can be avoided, preventing the corrosion of the base of the discharging arm and extending the service life of the base of the discharging arm.

[0026] Furthermore, a plurality of first gussets 4 are circumferentially arranged on the side of the panel 3 close to the first enclosing plate 1, and two sides of the first gusset 4 are respectively connected to the first enclosing plate 1 and the panel 3. A plurality of second gussets 5 are circumferentially arranged on the side of the panel 3 close to the second enclosing plate 2, and two sides of the second gusset 5 are respectively connected to the second enclosing plate 2 and the panel 3.

[0027] Specifically, the contact area between the panel 3 and the first enclosing plate 1 and the second enclosing plate 2 is small. After welding the panel 3 to the first enclosing plate 1 and the second enclosing plate 2, the overall strength is low. Therefore, in the present utility model, two right-angled sides of the first elbow plate 4 are respectively welded to the panel 3 and the first enclosing plate 1, and the other right-angled side of the first elbow plate 4 is welded to the deck of the ship, fixedly connecting the entire unloading arm base to the deck. Similarly, two right-angled sides of the second elbow plate 5 are respectively welded to the panel 3 and the second enclosing plate 2. By installing the first elbow plate 4 and the second elbow plate 5, the stability and mechanical strength of the entire unloading arm base are improved.

[0028] Furthermore, the heights of the first elbow plate 4, the first enclosing plate 1, and the second enclosing plate 2 are all the same.

[0029] Specifically, the first elbow plate 4 includes three right-angled sides, two of which are connected to the panel 3 and the first enclosing plate 1, and the remaining right-angled side is welded to the deck of the ship. Therefore, it is necessary to ensure that the height of the first elbow plate 4 is equal to the height of the first enclosing plate 1. Secondly, to ensure the horizontality of the panel 3, the heights of the first enclosing plate 1 and the second enclosing plate 2 are also equal.

[0030] Furthermore, cutouts 41 are provided at both right-angled vertices of the first elbow plate 4 and at the right-angled vertex of the second elbow plate 5.

[0031] Specifically, as a preferred solution of the present utility model, through the provision of the cutouts 41, stress concentration during the welding process can be effectively avoided, further improving the strength of the entire unloading arm base.

[0032] Furthermore, a maintenance hole 12 is provided on the surface of one of the first enclosing plates 1, and the maintenance hole 12 communicates with the interior of the polygonal enclosure structure.

[0033] Specifically, after the entire unloading arm is installed, a slewing mechanism will be installed inside the base. A maintenance hole 12 is provided on the surface of the first enclosing plate 1 for the maintenance of the internal slewing mechanism.

[0034] Furthermore, an installation opening 31 is provided on the surface of the panel 3, and the area size of the installation opening 31 is smaller than the area size of the polygonal enclosure structure.

[0035] Specifically, the shape of the installation opening 31 is the same as the shape of the polygonal enclosure structure. After the entire unloading arm base is welded to the ship deck, other components such as the slewing mechanism need to be installed in the installation opening 31.

[0036] Embodiment Two

[0037] A ship unloading arm includes the novel unloading arm base structure described in the first embodiment, and further includes a slewing platform 6 and a driving source 7. The slewing platform 6 is connected to the panel 3, the driving source 7 is arranged at the bottom of the slewing platform 6, and the output end of the driving source 7 is connected to the slewing platform 6.

[0038] Specifically, the function of the slewing platform 6 is to realize the rotation of the entire unloading arm. The rotating unloading arm is used to transport the goods on the dock to the ship, or transport the goods on the ship to the dock. The movement of the slewing platform 6 needs to be driven by the driving source 7, and is specifically completed through the meshing transmission of multiple gears.

[0039] Further, a fire-fighting pipeline 8 is arranged at the center of the slewing platform 6, and a rotary joint 81 is arranged at one end of the fire-fighting pipeline 8.

[0040] Specifically, the fire-fighting pipeline 8 directly leads into the unloading arm from the slewing platform 6 and is used to promptly remedy the fire accidents on the deck or the dock. As a preferred solution of the present utility model, the fire-fighting pipeline 8 needs to rotate synchronously with the unloading arm, so a rotary joint 81 is arranged at the end of the fire-fighting pipe.

[0041] In summary, the present utility model discloses a novel unloading arm base structure and a ship unloading arm. The structure of the entire unloading arm base is simple. During the assembly process, it is assembled with the slewing mechanism by direct welding, which greatly reduces the assembly difficulty. Secondly, through the drain port 11 at the bottom of the first enclosing plate 1, the water accumulation inside the unloading arm base can be avoided, preventing the corrosion of the unloading arm base and prolonging the service life of the unloading arm base.

[0042] Obviously, the above embodiments are only examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
