AI Technical Summary
When conventional container ships without cranes are fitted with deck cranes, the area between the deck stripes between cargo holds is narrow, which requires significant modifications to the cargo hold layout and presents a major design challenge.
A crane support structure is installed at the bottom of the cargo hold. The crane body is located above the hatch cover and occupies the hatch cover and cargo hold container space, rather than the traditional deck strip area. By limiting the number of crane bodies and support structures occupied, the loss of container placement space is reduced.
This approach avoids significant modifications to the original ship design, minimizes the impact on container placement, and reduces the influence on the overall longitudinal strength of the ship and the local strength of the cargo hold, providing a compact and economical crane installation solution.

DETAILED DESCRIPTION
[0030] The following description is used to explain the present application in detail so that those skilled in the art can implement the present application. The preferred embodiments in the following description are only examples, and other obvious modifications can be conceived by those skilled in the art. The basic principles defined in the following description can be applied to other embodiments, modifications, improvements, equivalents and other technical solutions without departing from the spirit and scope of the present application.
[0031] Please refer to Figures 1-3 The present application provides a technical solution: a crane arrangement structure of a container ship, comprising:
[0032] The ship body 100 is provided with a plurality of cargo holds 101, and deck strip areas are reserved between adjacent cargo holds 101. A hatch cover 102 is arranged above the cargo hold 101, and an array of hatch cover container positions 1021 is arranged above the hatch cover 102. An array of cargo hold container positions 1011 is arranged in the cargo hold 101, and a hatch opening 1022 is formed in the hatch cover 102 to communicate with the cargo hold 101.
[0033] The crane 204 is arranged on the crane cylinder, which 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. The fixed end 201 is connected to the bulkhead of the cargo hold 101, and the crane cylinder 205 is connected to the crane cylinder support structure 200 through the hatch opening 1022. The crane cylinder 205 is arranged between the hatch cover container positions 1021 in a manner avoiding the deck strip area, and the crane cylinder support structure 205 is arranged between the cargo hold container positions 1011. The number of lower container positions 1021 occupied by the crane cylinder 205 is not more than two rows, and the number of cargo hold container positions 1011 occupied by the crane cylinder support structure 200 is not more than one row. By connecting the crane cylinder support structure 200 to the bottom 103 of the cargo hold 101, the overall crane is installed, and the crane cylinder 205 and the support structure 200 are arranged between the hatch cover container positions 1021 and the cargo hold container positions 1011, rather than in the deck strip area between the two adjacent cargo holds 101. This avoids the need to significantly modify the original ship design when installing the crane cylinder 205 and the support structure 200. By limiting the number of cargo hold container positions 1011 and hatch cover container positions 1021 occupied by the crane cylinder 205 and the support structure 200, the loss of container placement positions caused by the installation of the crane is further reduced.
[0034] The crane barrel support structure 200 is located at the bow and / or stern of the ship body 100 in the length direction of the ship body 100, and the fixed end 201 of the crane barrel support structure 200 is arranged close to the bulkhead of the cargo hold 101. In the width direction of the ship body 100, the crane barrel support structure 200 is arranged close to the center of the ship body 100. Specifically, the number of cargo hold container positions 1011 and hatch cover container positions 1021 is determined according to the position of the crane body 200 on the ship body 100. Through the above definition, the influence on the overall longitudinal strength of the ship and the local strength of the cargo hold 101 after adding the crane body 200 can be minimized.
[0035] Further, gaps are reserved between the crane barrel 205 and the adjacent hatch cover container position 1021, and between the crane barrel support structure 200 and the adjacent cargo hold container position 1011. The minimum distance between the crane barrel 205 and the adjacent hatch cover container position 1021, and the minimum distance between the crane barrel support structure 200 and the adjacent cargo hold container position 1011 in the cargo hold 101 should ensure that the hoisting of containers is not affected.
[0036] Referring to Figure 4 Further, the arrangement further comprises:
[0037] The hatch cover 300 is movably connected to the top plate of the hatch cover enclosure 400 to open and close the hatch 1022. A through hole 301 is formed on one side of the hatch cover 300 in the circumferential direction, and the crane barrel 205 is located in the through hole 301. The hatch cover 300 is in the shape of a whole U.
[0038] Further, the hatch cover 300 comprises a plurality of cover pieces 302 connected to the top plate of the hatch cover enclosure 400. Adjacent cover pieces 302 are connected in sequence in the width direction of the ship body 100. One of the cover pieces 302 is provided with the through hole 301. Preferably, the through hole 301 is located close to the center of the ship body 100 in the width direction of the ship body 100. The cover piece 302 is provided with a side in the width direction of the ship body 100 。In one of the embodiments, the number of the cover plates 302 is three, the sizes of the cover plates 302 are different, the through hole 301 is arranged on the cover plate 302 at the middle position in the width direction of the ship body 100, the cover plate 302 is a rectangular cover plate 302, and the through hole 301 is arranged at the corner of the cover plate 302. The hatch cover 300 is divided into three asymmetrically arranged cover plates 302. Different from the arrangement of the crane cylinder 205 in the deck strip area, the crane cylinder occupies and sacrifices part of the hatch cover area, and the asymmetric hatch cover 300 is designed, so that the ship body is not greatly modified, the influence on the container position is small, and the structure is compact.
[0039] Referring to Figure 5 , further, the arrangement structure further comprises:
[0040] The hatch coaming 400 is arranged along the cargo hatch, and includes the part of the through hole 301 and the edge of the through hole 301;
[0041] The stopper 303 is arranged between the hatch coaming 400 and the crane cylinder 205, and the operation and maintenance space 401 is further arranged between the hatch coaming 400 and the crane cylinder 205.
[0042] For the specific structure of the crane cylinder 205 and the crane cylinder support structure 200, refer to Figure 1 and Figure 5 The crane 204 is arranged on the crane cylinder 205, 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 container position 1011, 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 of the crane cylinder support structure 200, and the cross-sectional size of the transition piece 203 gradually decreases close to the crane cylinder 205. By limiting the cross-sectional size between the crane cylinder 205 and the crane cylinder support structure 200, the crane cylinder support structure 200 with a larger cross-sectional size contacts the bulkhead of the cargo hold 101, the connection position of the crane cylinder support structure 200 and the crane cylinder 205 is smoothly transitioned, and the stable support of the crane cylinder support structure 200 on the crane cylinder 205 is ensured.
[0043] In order to conveniently reserve the maintenance operation space between the crane body 200 and the hatch 1022, and conveniently maintain the hatch cover 300 in the hatch 1022 through the maintenance operation space during use, further, the crane cylinder 205 with a smaller size is located in the hatch 1022.
[0044] To increase the continuity of the crane cylinder support structure 200 with large size and the crane cylinder 205, the transition piece 203 is arranged close to the hatch 1022, and further, the connection between the crane cylinder 205 and the transition piece 203 is flush with the lower end surface of the hatch 1022, so that the crane cylinder support structure 200 has a large proportion, which can stably support the crane cylinder 205.
[0045] In the vertical direction, the crane cylinder support structure 200 occupies one column of the cargo compartment container positions 1011, and the crane cylinder 205 occupies two columns of the hatch cover container positions 1021.
[0046] In summary, the arrangement structure has the following advantages:
[0047] 1. The crane cylinder support structure 200 does not need to modify the original structure of the ship body 100 in a large range, and has less damage to the ship body 100;
[0048] 2. The arrangement of the crane cylinder support structure 200 is compact, which reduces the loss of containers;
[0049] 3. Reducing the influence on the overall longitudinal strength of the ship body 100 and the local strength of the cargo compartment 101;
[0050] 4. The U-shaped asymmetric hatch cover 300 is adopted, compared with the large deck bar area required by the traditional hatch cover 300, the ship body is not greatly modified, the influence on the container position is small, and the structure is compact;
[0051] 5. Whether in design, construction, modification period, economy, etc., the difficulty of adding a crane to a container ship without a crane is greatly reduced, and a better crane installation scheme is provided for the ship owner.
[0052] The above design does not need to modify the original structure of the cargo compartment 101 area of the container ship in a large range, and has negligible influence on the original ship longitudinal strength envelope.
