Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to an integrated structure of a container ship lashing bridge and a crane. Background Art

[0002] Container ships are usually equipped with lashing bridges and cranes.

[0003] In order to stack more and higher layers of containers on the open deck, a lashing bridge is usually set up. The lashing bridge provides a stable lashing support for the containers; the setting of the lashing bridge makes it possible to stack heavy containers at a higher position. The shear plates of the container ship lashing bridge are generally set near the midship and the side to jointly bear the lateral shear force from the lashing rods.

[0004] Most feeder container ships have cranes arranged in the middle, at the same longitudinal position as the lashing bridge. The shape of the crane base of a container ship is generally "round sky and square earth", that is, the bottom is square and the top is round. The bottom of the crane is a rectangular cylinder. The middle deck must be wide enough to ensure space for the crane base, lashing bridge equipment, hatch covers and lashing operations.

[0005] Currently, the lashing bridges and cranes on container ships are installed independently.

[0006] Compared with ships without cranes, in order to obtain the same number of containers, the conventional solution for ships equipped with cranes is to increase the distance between the front and rear columns of the lashing bridge, thereby increasing the overall length and the length of the compressor room area. Figure 1 As shown, the ship 91 without crane has a width of middle deck of 1.7m and a total length of 182.66m. Figure 2 As shown in the figure, under the same number of container positions, the width of the middle deck of the crane-equipped ship 92 is 3.28m, and the total length of the ship is 185.8m. In comparison, the total length of the crane-equipped ship 92 is increased by about 3.14m, and the engine room is compressed by 1.6m.

[0007] The prior art has the following disadvantages: the configuration of a crane leads to a significant increase in the length of the ship, an increase in the weight of the structure, an increase in the resistance of the ship and thus an increase in fuel consumption, which affects the economic performance of the ship. Summary of the invention

[0008] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide an integrated structure of a container ship lashing bridge and a crane.

[0009] The present invention solves the above technical problems through the following technical solutions:

[0020] The beneficial effects of the present invention are as follows: the present invention integrates the lashing bridge and the crane into one body, saves the gap between the crane and the column on the middle deck, and makes the arrangement of the ship type along the length direction more compact. The present invention can make it more convenient to use the inner lashing for the containers in front and behind the rectangular cylinder of the crane; and can also make the lower part of the crane cylinder also serve as the shear plate in the middle position. The present invention can reduce the length of the ship, reduce the weight of the structure, reduce the resistance of the ship, thereby reducing the fuel consumption, and improve the economic performance of the ship.

[0030] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, an integrated structure of a container ship lashing bridge and a crane is arranged between the lashing bridge 30 and a rectangular cylinder 10 located at the bottom of the crane. The lashing bridge 30 and the rectangular cylinder 10 are arranged on the hatch coaming 20 in the middle deck area.

[0031] The lashing bridge 30 comprises a first platform 31 and a second platform 32 ; the first platform 31 is located between the hatch coaming 20 and the second platform 32 .

[0032] The rectangular cylinder 10 is a frame structure. The rectangular cylinder 10 is arranged through the first platform 31 and the second platform 32 ; the rectangular cylinder 10 extends downward to the bottom of the hatch coaming 20 ; the first platform 31 and the second platform 32 are fixed to the rectangular cylinder 10 .

[0033] The rectangular cylinder 10 includes a front panel 11, a left panel 13, a rear panel 12 and a right panel 14 which are connected in sequence, and the front panel 11, the left panel 13, the rear panel 12 and the right panel 14 form a rectangle.

[0034] Four support columns 40 are arranged in the rectangular cylinder 10 ; the four support columns 40 are respectively arranged in four right angles of the rectangular cylinder; the support columns 40 extend from the hatch coaming to the top of the second-level platform 32 .

[0035] In this embodiment, the support column includes two mutually perpendicular sealing plates 41, which are fixed to the inner wall of the rectangular cylinder; the two sealing plates and the right-angled ends of the rectangular cylinder form a rectangle. The sealing plates extend from the top of the hatch coaming to the top of the second-level platform. In this embodiment, the sealing plates and the right-angled ends of the rectangular cylinder form a support column.

[0036] A large door opening 50 for internal binding operation is respectively formed on the front wall plate 11 and the rear wall plate 12 ; the large door opening 50 is located above the second-layer platform 32 .

[0037] The large door opening is located above the second-level platform, providing a large enough space for internal tying operations.

[0038] A first small door opening 61 serving as a hatch cover operation passage is respectively formed on the left enclosure plate 13 and the right enclosure plate 14 . The first small door opening 61 is located between the first platform 31 and the second platform 32 .

[0039] A second small door opening 62 for a lashing operation passage is respectively formed on the left enclosure plate 13 and the right enclosure plate 14 . The second small door opening 62 is located above the second-layer platform 32 .

[0040] The portion of the front panel 11 between the first platform 31 and the second platform 32 and the portion of the rear panel 12 between the first platform 31 and the second platform 32 are both shear panels of the lashing bridge.

[0041] That is to say, the part of the front panel between the first platform and the second platform, and the part of the rear panel between the first platform and the second platform both serve as shear panels of the lashing bridge.

[0042] The parts of the four supporting columns 40 above the second-layer platform 32 are all lashing columns for lashing bridges. In other words, the parts of the four supporting columns above the second-layer platform all serve as lashing columns for lashing bridges.

[0043] Both the first platform 31 and the second platform 32 are provided with eaves 34 , and the eaves 34 are fixedly connected to the rectangular cylinder 10 .

[0044] A first bottom plate 71 is disposed in the rectangular cylinder 10 , and the first bottom plate 71 is flush with the first platform 31 .

[0045] A second bottom plate 72 is disposed in the rectangular cylinder 10 , and the second bottom plate 72 is flush with the second platform 32 .

[0046] The support column 40 is provided with a lashing rod 33 at a portion above the second platform 32 .

[0047] The large door opening on the front panel 11 is arranged between two adjacent support pillars on the front panel, and the large door opening on the rear panel 12 is arranged between two adjacent support pillars on the rear panel.

[0049] The second small door opening on the left enclosure plate 13 is arranged between two adjacent support columns on the left enclosure plate, and the second small door opening on the right enclosure plate 14 is arranged between two adjacent support columns on the right enclosure plate.

[0050] The rectangular cylinder 10 is generally located near the centerline 80 of the ship.

[0051] In the present invention, the lashing bridge structure is connected to the rectangular cylinder structure of the crane. The present invention connects the platforms of each layer of the lashing bridge and the rectangular cylinder of the crane transversely through the platform plate and the platform eaves plate to form a whole.

[0052] In the present invention, the front and rear panels of the rectangular cylinder of the crane also serve as shear plates in the middle of the lashing bridge. The two left and right shear plates in the middle of the existing lashing bridge design are eliminated, and the thick and rigid front and rear panels of the rectangular cylinder of the crane are used to bear the lateral shear force in the middle.

[0053] In the present invention, a platform is arranged at the height of the lashing bridge platform, and a first small door opening and a second small door opening are provided on the left and right enclosures of the rectangular cylinder of the crane on the platform to serve as a hatch cover operation channel and a lashing operation channel.

[0054] In the present invention, on the second-layer platform of the lashing bridge, large door openings are provided on the front and rear panels of the rectangular cylinder of the crane for lashing operations, thereby facilitating lashing operations of containers in front and behind the crane.

[0055] In the present invention, the four corners of the rectangular cylinder of the crane are embedded with support columns as compensation for the opening. In order to compensate for the influence of the opening of the rectangular cylinder of the crane on the structural strength, support columns are embedded in the four corners of the rectangular cylinder. For example, the size of the support column can be 500×500mm. The embedded support column also serves as the lashing column of the middle box position.

[0056] With Figure 1 and Figure 2 When the ships in the same number of containers are equipped, Figure 8 As shown, the ship 93 of this embodiment has a width of the middle deck on which the crane is installed of 2.6 m and a total length of 183.76 m. Figure 2 Compared with the Zhongchuan 92, the width of the middle deck is reduced and the overall length of the ship is shortened.

[0057] The present invention can reduce the length of the ship, reduce the structural weight, reduce the resistance of the ship and thus reduce the fuel consumption, and improve the economic performance of the ship.

[0058] The present invention integrates the lashing bridge and the crane into one body, thereby saving the gap between the crane and the column on the middle deck, and making the arrangement of the ship type along the length direction more compact.
