Description

Technical Field

[0001] The utility model relates to the technical field of packing assistance, in particular to a packing assistance device in a container cargo hold. Background Art

[0002] With the growing development of international trade, container shipping based on trade has emerged and matured. Large container ships are high-tech, high-value-added ships and are one of the key development ship types in the world's shipbuilding industry.

[0003] Modern container ships have stepped high and low platform in the cargo hold to increase the loading capacity. Some ship types take into account the mixed stacking of high-box and standard containers. The height of each step of the high and low platform in the cargo hold is generally designed according to the height of the high container. Therefore, when stacking 20-foot standard containers, there will be a certain height difference between the 20-foot standard container located on the high and low platform and the adjacent 20-foot standard containers placed directly in the cargo hold. This makes it impossible for a 40-foot container to be placed stably on top of two adjacent standard containers. Although the 20-foot high container can fill the gap at the high and low platform, the 20-foot high container is not mainstream. The transporter often needs to prepare empty 20-foot high containers to cope with the gap between the high and low platform, which will reduce the actual loading capacity.

[0004] Therefore, we have made improvements to this problem and proposed a loading auxiliary device in the container cargo hold. Summary of the Invention

DETAILED DESCRIPTION

[0025] To better understand the technical solution of the present invention, the following detailed description is provided with reference to the relevant illustrations. It should be understood that the following specific embodiments are not intended to limit the specific implementation of the technical solution of the present invention; they are merely examples of possible implementations of the technical solution of the present invention. It should be noted that the description herein of the positional relationships of the various components, such as component A being located above component B, is based on the relative positions of the components in the illustrations and is not intended to limit the actual positional relationships of the components. Example 1

[0026] See also Figure 1-Figure 7 , Figure 1 A schematic structural diagram of the present invention is provided. As shown in the figure, the present invention relates to a container loading assistance device in a cargo hold, comprising a base 2 placed in a cargo hold 18, a high-low box platform 1 provided in the cargo hold 18, and a top plate 21 and a bottom plate 22. The top plate 21 is positioned above the bottom plate 22, and a plurality of square tubes 23 are fixedly connected between the top plate 21 and the bottom plate 22. A plurality of second screws 5 are fixedly connected to the bottom of the top plate 21, and threaded sleeves 6 are threadedly connected to the lower half of the outer circumference of the second screws 5. A clearance opening 7 is defined at the top of the bottom plate 22 corresponding to the threaded sleeves 6. The bottom surface of the cargo hold 18 is defined at the front and rear sides of the high-low box platform 1, and a first screw 4 is fixedly connected to the bottom wall of the bottom groove 3. The threaded sleeves 6 pass through the corresponding clearance openings 7 and extend into the corresponding bottom groove 3, and the lower half of the threaded sleeves 6 are threadedly connected to the corresponding first screw 4.

[0027] The height of one step of the high-low box platform 1 is equal to the height of the high-low box, and the height of the standard container plus the sum of the height of the base 2 is equal to the height of the high-low box. Therefore, when the base 2 is fixed to the front and rear sides of the high-low box platform 1, when a standard container is placed on the base 2, the height of this standard container is equal to the height of the step of the high-low box platform 1. Therefore, a 40-foot long container can be placed on this standard container and the high-low box platform 1.

[0028] like Figure 3-5 As shown, as a preferred embodiment, on the basis of the above method, further, a plurality of accommodating cavities 8 are opened on the inner wall of the cargo hold 18, the inner bottom wall of the accommodating cavity 8 is coplanar with the bottom surface of the cargo hold 18, and the top surface of the first screw 4 is located below the top surface of the bottom groove 3, so when the container is placed directly on the bottom surface of the cargo hold 18, it will not contact the first screw 4.

[0029] When there are enough high boxes that need to be transported, the base 2 is no longer needed. The high boxes can be placed directly on the front and back sides of the high and low box platform 1. At this time, the staff can push the base 2 into the corresponding accommodating cavity 8 for collection, reducing the space occupied in the cargo hold 18.

[0030] When removing the base 2 , the staff rotates the threaded sleeve 6 to move the threaded sleeve 6 upward until the threaded sleeve 6 is separated from the first screw 4 and partially moves into the avoidance opening 7 . At this time, the base 2 can be pushed directly.

[0031] like Figure 4-5 As shown, as a preferred embodiment, on the basis of the above method, further, a plurality of slots 9 are opened on the top of the top plate 21, a plurality of top slots 10 are opened on the top wall of the accommodating cavity 8, a screw sleeve 11 is rotatably connected to the top wall of the top slot 10, a screw sleeve 11 is threadedly connected to the lower half of the screw sleeve 11, a clamping block 13 is fixedly connected to the bottom end of the screw sleeve 12, the clamping block 13 is slidably connected to the top slot 10, and a driving part is provided on one side of the screw sleeve 11.

[0032] The driving part includes a side groove 14 opened on the inner wall of the cargo hold 18, and a worm 15 is rotatably connected in the side groove 14. The worm 15 partially extends into the top groove 10. One end of the worm 15 is fixedly connected to a turntable 16, and the turntable 16 is completely located in the side groove 14. A worm gear 17 is fixed on the outer peripheral side of the screw sleeve 11, and the worm 15 is meshed with the corresponding worm gear 17.

[0033] After placing the base 2 in the accommodating chamber 8, the staff rotates the turntable 16, driving the worm 15 to rotate, the worm 15 drives the worm wheel 17 to rotate, the worm wheel 17 drives the screw sleeve 11 to rotate, and the screw sleeve 11 drives the screw 12 and the block 13 to move downward, so that the block 13 is inserted into the corresponding slot 9 until the bottom surface of the block 13 fits with the bottom wall of the slot 9, and the side wall of the block 13 also fits with the inner wall of the slot 9, thereby fixing the base 2 in the accommodating chamber 8 to prevent the base 2 from sliding out of the accommodating chamber 8 when the freighter shakes.

[0034] like Figure 4-5 As shown, as a preferred embodiment, on the basis of the above method, further, when several card blocks 13 are located directly above the corresponding card slots 9, the three side walls of the base 2 are respectively fitted with the three inner walls of the accommodating cavity 8. Therefore, when the staff places the base 2, they only need to push the base 2 to fit with the inner wall of the accommodating cavity 8. At this time, it can be ensured that the card slot 9 is located directly below the card block 13, which makes it convenient for the staff to store the base 2.

[0035] Working principle:

[0036] The utility model provides a packing auxiliary device in a container cargo hold, which, when in use:

[0037] Under normal circumstances, the transported container does not have enough high boxes, and the staff needs to place the standard box on the base 2 to fill the height difference between the standard box and the high and low box platform 1.

[0038] When the transported container has enough high boxes, the base 2 is no longer needed. The staff rotates the threaded sleeve 6 to make the threaded sleeve 6 move upward until the threaded sleeve 6 disengages from the first screw 4 and partially moves into the avoidance opening 7. At this time, the base 2 can be directly pushed into the accommodating chamber 8, and the side wall of the base 2 fits into the inner wall of the accommodating chamber 8. Then the turntable 16 is rotated to drive the worm 15 to rotate, the worm 15 drives the worm wheel 17 to rotate, the worm wheel 17 drives the threaded sleeve 11 to rotate, and the threaded sleeve 11 drives the screw 12 and the block 13 to move downward, so that the block 13 is inserted into the corresponding slot 9 to fix the base 2 in the accommodating chamber 8.

[0039] When the base 2 needs to be used later, rotate each turntable 16 in the opposite direction so that the block 13 moves upward and disengages from the slot 9, pull the base 2 out of the accommodating cavity 8, and push it to the appropriate position (the threaded sleeve 6 is located directly above the first screw 4), then rotate each threaded sleeve 6 so that the threaded sleeve 6 moves downward and is threadedly connected to the first screw 4, thereby fixing the base 2 in place.

[0040] The above are only specific application examples of the present invention and do not constitute any limitation on the scope of protection of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the scope of protection of the present invention.
