DETAILED DESCRIPTION

[0030] The following description is used to fully explain the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0031] See also Figure 1-3 The present invention provides a technical solution: a crane arrangement structure for a container ship, comprising:

[0032] A ship body 100, wherein the ship body 100 is provided with a plurality of cargo holds 101, a deck strip area is reserved between adjacent cargo holds 101, a hatch cover 102 is provided above the cargo hold 101, a hatch cover container position 1021 arranged in an array is provided above the hatch cover 102, a cargo hold container position 1011 arranged in an array is provided in the cargo hold 101, and a hatch 1022 connected to the cargo hold 101 is opened on the hatch cover 102;

[0033] The crane 204 is arranged on the crane cylinder, and the crane cylinder is supported by the crane cylinder support structure 200. The two ends of the crane cylinder support structure 200 in the length direction are respectively a fixed end 201 and a free end 202, and the fixed end 201 is connected to the bulkhead of the cargo hold 101. The crane cylinder 205 passes through the hatch 1022 and is connected to the crane cylinder support structure 200. The crane cylinder 205 is arranged between the hatch cover container positions 1021 in a manner of avoiding the deck strip area, and the crane cylinder support structure 205 is arranged between the cargo hold container positions 1011, wherein the number of lower container positions 1021 occupied by the crane cylinder 205 does not exceed two rows, and the number of cargo hold container positions 1011 occupied by the crane cylinder support structure 200 does not exceed one row. By connecting the crane cylinder supporting structure 200 to the bottom 103 of the cargo hold 101, the installation of the entire crane is achieved, wherein the crane cylinder 205 and the supporting structure 200 are located between the hatch cover container space 1021 and the cargo hold container space 1011, rather than in the traditional deck strip area between two adjacent cargo holds 101, thereby avoiding the need to make major modifications to the original ship design when installing the crane cylinder 205 and the supporting structure 200. By limiting the number of cargo hold container spaces 1011 and hatch cover container spaces 1021 occupied by the crane cylinder 205 and the supporting structure 200, the loss of container placement space caused by the installation of the crane is further reduced.

[0034] In the length direction of the ship body 100, the crane cylinder support structure 200 is located at the bow and / or stern of the ship body 100, and the fixed end 201 of the crane cylinder support structure 200 is arranged in a manner close to the bulkhead of the cargo hold 101. In the width direction of the ship body 100, the crane cylinder support structure 200 is arranged in a manner close to the center of the ship body 100. Specifically, depending on the position of the crane body 200 on the ship body 100, the number of cargo hold container positions 1011 and hatch cover container positions 1021 is determined. Through the above definition, after the crane body 200 is installed, the impact on the overall longitudinal strength of the entire ship and the local strength of the cargo hold 101 can be minimized.

[0035] Furthermore, a gap is reserved between the crane cylinder 205 and the adjacent hatch cover container position 1021, and between the crane cylinder support structure 200 and the adjacent cargo hold container position 1011. The minimum spacing between the crane cylinder 205 and the adjacent hatch cover container position 1021, and the minimum spacing between the crane cylinder support structure 200 and the adjacent cargo hold container position 1011 in the cargo hold 101 should ensure that container lifting is not affected.

[0036] See also Figure 4 , further, the arrangement structure also includes:

[0037] The hatch cover 300 is movably connected to the top plate of the hatch cover 400 in a manner of opening and closing the hatch opening 1022. A through hole 301 is opened on one side of the circumference of the hatch cover 300, and the crane cylinder 205 is located in the through hole 301. The hatch cover 300 is U-shaped as a whole.

[0038] Furthermore, the hatch cover 300 includes a plurality of cover sheets 302, the cover sheets 302 are connected to the top plate of the hatch coaming 400, and the adjacent cover sheets 302 are sequentially connected in the width direction of the ship body 100, and one of the cover sheets 302 is provided with the through opening 301, preferably, the through opening 301 is close to the side of the ship in the width direction of the ship body 100, and the cover sheet 302 is close to the side of the ship in the width direction of the ship body 100. 。In one embodiment, the number of the cover pieces 302 is 3, and the sizes of the cover pieces 302 are different. The cover piece 302 in the middle position in the width direction of the ship body 100 is provided with the opening 301. The cover piece 302 is a rectangular cover piece 302, and the opening 301 is located at the corner of the cover piece 302. The hatch cover 300 is divided into 3 asymmetrically arranged cover pieces 302. Different from arranging the crane cylinder 205 in the deck strip area, the crane cylinder of this solution occupies and sacrifices part of the hatch cover area, adopts an asymmetrical hatch cover 300 design, avoids major modification of the hull, has little impact on the container space, and has a compact structure.

[0039] See also Figure 5 , further, the arrangement structure also includes:

[0040] a hatch coaming 400, the hatch coaming 400 being arranged along the cargo hold hatch, including a portion of the through-opening 301 and an edge of the through-opening 301;

[0041] A stopper 303 is provided between the hatch coaming 400 and the crane cylinder 205 , and an operation and maintenance space 401 is also provided between the hatch coaming 400 and the crane cylinder 205 .

[0042] For details on the structure of the crane barrel 205 and the crane barrel support structure 200, see Figure 1 and Figure 5 The crane 204 is arranged on the crane cylinder 205, and the crane cylinder 205 is supported by the crane cylinder support structure 200. The transition piece 203 connects the crane cylinder 205 and the crane cylinder support structure 200. The crane cylinder support structure 200 is located in the cargo hold container position 1011, and the crane cylinder 205 is located in the hatch cover container position 1021. The cross-sectional size of the crane cylinder 205 is not greater than the smallest cross-sectional size on the crane cylinder support structure 200, and the cross-sectional size of the transition piece 203 gradually decreases as it approaches the crane cylinder 205. By limiting the cross-sectional dimensions between the crane barrel 205 and the crane barrel supporting structure 200, the crane barrel supporting structure 200 having a larger cross-sectional dimension contacts the bulkhead of the cargo hold 101, and the connection position between the crane barrel supporting structure 200 and the crane barrel 205 has a smooth transition, thereby ensuring that the crane barrel supporting structure 200 stably supports the crane barrel 205.

[0043] In order to facilitate the maintenance and operation space to be reserved between the crane body 200 and the hatch 1022, when in use, the hatch cover 300 in the hatch 1022 can be conveniently inspected through the maintenance and operation space. Furthermore, the smaller-sized crane cylinder 205 is located in the hatch 1022.

[0044] In order to increase the continuity between the larger crane barrel support structure 200 and the crane barrel 205, the transition piece 203 is arranged close to the hatch 1022. Furthermore, the connection between the crane barrel 205 and the transition piece 203 is flush with the lower end surface of the hatch 1022, so that the crane barrel support structure 200 has a larger proportion and can stably support the crane barrel 205.

[0045] In the vertical direction, the crane cylinder supporting structure 200 occupies one row of the cargo hold container spaces 1011 , and the crane cylinder 205 occupies two rows of the hatch cover container spaces 1021 .

[0046] In summary, this arrangement has the following advantages:

[0047] 1. The installation of the crane barrel support structure 200 does not require extensive modification of the original structure of the ship body 100, and the damage to the ship body 100 is relatively small;

[0048] 2. The installation of the crane barrel support structure 200 makes the layout compact and reduces the impact of losses on containers;

[0049] 3. Reduce the impact on the overall longitudinal strength of the ship body 100 and the local strength of the cargo hold 101;

[0050] 4. The U-shaped asymmetric hatch cover 300 design avoids major hull modification, has less impact on container space and has a compact structure compared to the traditional hatch cover 300 which requires a larger deck strip area;

[0051] 5. Whether in terms of design, construction, modification period or economy, it greatly reduces the difficulty of installing cranes on container ships without cranes, and provides ship owners with a better solution for installing cranes.

[0052] The above design does not require extensive modification of the original structure of the container ship cargo hold area 101, and the impact on the original ship's total longitudinal strength envelope can be ignored.

[0053] The embodiments described above are only used to illustrate the technical ideas and features of the present invention, and their purpose is to enable technicians in this field to understand the contents of the present invention and implement them accordingly. The patent scope of the present invention cannot be limited only by this embodiment, that is, any equivalent changes or modifications made according to the spirit disclosed by the present invention still fall within the patent scope of the present invention.
