[0039] Reference below Figure 1-Figure 7 The ship structural lifting structure according to the embodiment of the utility model is described.

[0040] like Figure 1-Figure 7 As shown, the ship structural lifting structure includes a lifting ring structure plate 200 and a crane beam 300 and a lifting rigging 400 for lifting the ship 100. The ship structural lifting structure of this embodiment is mainly used in the transportation and lifting of small and medium-sized ships 100, and adopts a fused structural design of the ship 100 to increase the overall structural strength of the ship 100, and avoid the lifting operation of the ship 100 repeatedly installing and lifting to affect the structural strength of the ship 100.

[0041] Specifically, the ship 100 includes a ship outer plate 110 and a ship main deck 120. The ship outer plate 110 is arranged on both sides of the ship main deck 120 and is provided with a strong rib 130 and an auxiliary rib 140. The ship 100 can be hoisted and transferred as a whole by a land crane or a floating crane in waters. When the ship 100 is built, the hoisting structure is arranged in advance to facilitate the hoisting and transfer of the ship 100 as a whole according to actual needs after construction.

[0042] The ship structural lifting structure of this embodiment includes a ring structure plate 200, a crane beam 300 and a lifting rigging 400. Specifically, the ring structure plate 200 is symmetrically arranged on the top of the two ship outer plates 110, and the ring structure plate 200 is arranged along the extension position of the ship outer plate 110. The ratio of the spacing between the ring structure plates 200 at the front and rear ends of the ship outer plate 110 on the same side to the length of the ship 100 is ≥0.5. That is, the front and rear distance of the ring structure plate 200 is L, and the design length of the L value is not less than half of the length of the ship 100, ensuring that the center of gravity of the crane beam 300 during the lifting process of the ship 100 is kept within a reasonable range. The same number of ring structure plates 200 are arranged on the ship outer plate 110 on each side of the ship 100, and the arrangement positions are symmetrical.

[0043] Two groups of crane beams 300 are provided, which are respectively arranged above the ship outer plate 110. A lifting rigging 400 is arranged below the crane beams 300. The two ends of the lifting rigging 400 are respectively connected to the crane beams 300 and the eye structure plate 200.

[0044] The ring structure plate 200 is integrally formed with the ship outer plate 110, the strong ribs 130 are aligned with the ring structure plate 200, and the auxiliary ribs 140 are arranged on both sides of the strong ribs 130. That is, the ship outer plate 110 and the ring structure plate 200 of the ship 100 are welded or fused to form a whole during the construction process, forming the overall structure of the ship 100 hoisting.

[0045] The ring structure plate 200 is integrated with the ship outer plate 110, and the structure is fixed, and no temporary setting is required. It can be used repeatedly, which effectively reduces the construction cost. The ring structure plate 200 and the strong ribs 130 are in the same straight line, and the strong ribs 130 of the ship outer plate 110 can be directly stressed when the ship 100 is hoisted, thereby ensuring the structural strength of the ship 100. The ring structure plate 200, the crane beam 300 and the lifting rigging 400 form a set of hoisting structures, and the ship 100 is hoisted as a whole by a land crane or a floating crane on water.

[0046] This embodiment performs a simple structural integration design on the structure of the small and medium-sized ship 100, adopts a design in which the hoisting structure is integrated into the structure of the ship 100, and expands the shipping method of the ship 100 without affecting the normal operation of the ship 100, providing a structure that can realize the overall hoisting of the ship 100, can be used repeatedly, and has a safe and relatively fixed structure. It is easy to use and has reliable performance, overcoming the problems of insufficient hoisting methods and methods of conventional ships 100, and the hoisting structure is safe, efficient, economical and practical, effectively ensuring the safe operation of the ship 100 itself.

[0047] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the number of the ring structure plates 200 provided on the single-side ship outer plate 110 is at least four groups.

[0048] Specifically, when hoisting the ship 100, the ring structure plates 200 are evenly arranged on both sides of the ship 100, that is, on the ship outer plate 110. This achieves the function of balancing the center of gravity of the ship during hoisting and meets the requirement of stable hoisting. The design quantity of the ring structure plates 200 is set according to the weight of the ship 100.

[0049] In some embodiments of the present invention, Figure 7 As shown, the ring structure plate 200 adopts a steel plate structure, and the thickness of the ring structure plate 200 is 15 mm to 25 mm.

The length and width of the ring structure plate 200 are b and h respectively, and the b value is generally the distance between two auxiliary ribs 140, and the h value is approximately equal to the b value, so that the ring structure plate 200 is a square structure as a whole, and the lifting ear of the ring structure plate 200 is on the same straight line as the strong rib 130. The size of the lifting hole of the lifting ear is selected to match the size and specifications of the lifting components.

[0051] In some embodiments of the present invention, Figure 5-Figure 7 As shown, the spacing between the ring structure plates 200 on the two ship outer plates 110 is equal to the width of the ship 100 .

[0052] Specifically, the ring structure plate 200 is arranged at the structural extension position of the ship outer plate 110 on both sides of the ship main deck 120, and the distance between the ship outer plates 110 on both sides is the width value of the ship 100.

[0053] In some embodiments of the present invention, Figure 5-Figure 7 As shown, the lifting ear portion of the lifting ring structure plate 200 protrudes from the top end surface of the ship outer plate 110 , and the plate-shaped portion of the lifting ring structure plate 200 is welded to the inner wall of the ship outer plate 110 .

[0054] Specifically, the shape of the plate-like portion of the ring structure plate 200 is adjusted according to different connection positions with the ship outer plate 110, and its shape can be a square or a long plate. The ring structure plate 200 and the ship outer plate 110 adopt an integral fusion structural design, which is not easy to cause deformation during the hoisting of the ship 100, and it is easy to meet the installation and construction requirements of the ship 100 structure, thereby improving the installation quality.

[0055] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the crane beam 300 includes a short beam 310 and a long beam 320 , and the short beam 310 and the long beam 320 are selected to have different lengths according to the actual lifting environment.

[0056] Specifically, the selection of the short beam 310 and the long beam 320 is determined according to the actual configuration of each crane, that is, they can be all short beams 310 or all long beams 320. During hoisting, the short beam 310 and the long beam 320 are respectively arranged at corresponding positions on the left and right sides of the ship 100.

[0057] In a further embodiment, Figure 1-Figure 3 As shown, lifting parts are arranged at equal intervals on the long lifting beam 320 and the short lifting beam 310, and the lifting parts adopt a pulley block structure.

[0058] Specifically, pulley block structures are provided at both ends of the short lifting beam 310 , and pulley block structures are provided at the middle and both ends of the long lifting beam 320 . In the actual lifting process, pulley block structures at different positions are selected according to the specifications of the ship 100 .

[0059] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the lifting rigging 400 includes an upper steel wire rope 410 , a shackle 420 and a lower steel wire rope 430 . The number of the lower steel wire ropes 430 matches the number of the eye structure plates 200 . The shackle 420 connects the upper steel wire rope 410 and the lower steel wire rope 430 respectively. The upper steel wire rope 410 is connected to the crane beam 300 .

[0060] Specifically, the number of the lifting ring structure plates 200 arranged on the same side ship outer plate 110 is an even number, the lower steel wire rope 430 of each two groups of lifting ring structure plates 200 is connected to a shackle 420, the shackle 420 is connected to an upper steel wire rope 410, and each two groups of upper steel wire ropes 410 are connected to a lifting position of the crane beam 300.

[0061] In a further embodiment, Figure 1-Figure 3 As shown, the angle between the lower wire rope 430 and the horizontal plane is greater than 45°. Specifically, in order to reduce the horizontal force of the lower wire rope 430, the angle between the lower wire rope 430 and the horizontal plane is kept greater than 45° during the hoisting process to improve the hoisting efficiency and stability.
