Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a deck height correction lifting tool and a ship. Background Technology

[0002] With the rapid development of the shipbuilding industry, the construction requirements for high-tech ships such as cruise ships and PCTC ships are becoming increasingly stringent. The hull structure generally adopts thin plate materials of 8mm and below. Although this design can effectively reduce the weight of the hull and improve cargo carrying efficiency, it also brings many construction challenges.

[0003] Thin-plate structures have relatively weak strength and rigidity, making them highly susceptible to deformation during construction. Particularly during segmented manufacturing, welding, and subsequent outfitting, welding stress, assembly stress, and external forces can cause varying degrees of deformation. Furthermore, uneven stress distribution on lifting equipment and vibrations during transport can further exacerbate deformation. This leads to inconsistencies in deck height at the same location during ship assembly or dry docking, often resulting from deformations during manufacturing and transportation. Specifically, beams or steel sections on the lower deck may bulge, while corresponding sections on the upper deck may be recessed. This height discrepancy directly impacts the ship's structural strength and the construction of outfitting and interior fittings. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a deck height correction lifting fixture and a ship to solve the problem that thin plate structures on the hull are prone to deformation, and when the upper and lower decks are assembled in sections, the lower deck may bulge upwards while the corresponding position on the upper deck may sag downwards, resulting in a deviation in deck height, which directly affects the structural strength of the ship and the outfitting and interior construction.

[0025] According to the present invention, a deck height correction lifting fixture is provided, which includes a lifting component 10, a support assembly, and a support component 40.

[0026] The specific structure of the aforementioned components of the deck height correction lifting fixture according to this embodiment will be described below.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the lifting member 10 has a reciprocating lifting end 11. The lifting member 10 can be a jack. The lifting end 11 can reciprocate in the direction of approaching or moving away from the main body of the lifting member 10. The reciprocating direction of the lifting end 11 is preferably a direction perpendicular to the plane of the deck, i.e., a vertical direction.

[0028] like Figure 1As shown, the support assembly includes a support member 20 and a guide member 30 mounted on the support member 20. A guide channel 31 is formed inside the guide member 30, and the lifting end 11 can extend into the guide channel 31. One end of the support member 40 is disposed inside the guide channel 31, and the other end of the support member 40 extends out of the guide channel 31 and can abut against the bottom of the deck. When the lifting end 11 abuts against the support member 40, the reciprocating drive of the lifting end 11 can drive the support member 40 to slide along the guide channel 31. The lifting end 11 abuts against the support member 40 to drive the support member 40 to slide along the guide channel 31 during tooling lifting. The area performs water and fire correction on the deck, constantly adjusting the jacking component 10 to change the height of the support component 40. Through heating combined with the external force applied by the tooling, the dented deck is lifted up, allowing the jacking tooling to assist in adjusting the height between the upper and lower decks. Support components 40 of different lengths can be replaced according to the deck height to meet different working conditions and improve the efficiency and accuracy of deck height repair. Support components 20 and guide components 30 can support and guide the sliding of the support component 40 to prevent the support component 40 from collapsing, reduce safety hazards during the deck height repair process, and improve the efficiency and safety of construction.

[0029] Preferably, a portion of the guide member 30 protrudes from the top of the support member 20, so that the guide channel 31 has sufficient length to prevent the carrier member from coming out of the guide channel 31; preferably, the connection position between the support member 20 and the guide member 30 is set at the middle of the length direction of the guide member 30.

[0030] In this embodiment, the support member 40 can be formed as a hollow tubular structure or a solid columnar structure. When the support member 40 is formed as a tubular structure, it is easier to move. When the support member 40 is formed as a columnar structure, the contact area between the support member 40 and the deck is larger, and the supporting effect is better.

[0031] Furthermore, in this embodiment, as Figure 1 As shown, the guide member 30 is formed as a tubular structure, such as a tubular structure with a circular or polygonal cross-section. The guide channel 31 is disposed inside the tubular structure and extends in the vertical direction to ensure the reliability and accuracy of the load-bearing member lifting the deck.

[0032] Preferably, the lifting end 11 and the guide channel 31 are in clearance fit, specifically, the circumferential sidewall of the lifting end 11 is smaller than the inner diameter of the tubular structure; the support member 40 and the guide channel 31 are in clearance fit, specifically, the circumferential sidewall of the support member 40 is smaller than the inner diameter of the tubular structure, so as to ensure that the lifting end 11 and the support member 40 slide smoothly in the guide channel 31.

[0033] Preferably, the gap between the lifting end 11 and the guide channel 31 is smaller than the gap between the support member 40 and the guide channel 31, so that at least part of the circumferential sidewall of the lifting end 11 protrudes radially from the circumferential sidewall of the support member 40, so as to ensure that the lifting end 11 and the support member 40 have sufficient contact area regardless of whether the support member 40 is formed as a tubular structure or a columnar structure, and to ensure that the lifting member 10 applies force to the support member 40 evenly and stably. Furthermore, in this embodiment, as Figure 1 As shown, the support member 20 includes a plurality of inclined support rods 21. The support rods 21 are formed into strip-shaped rod structures. In this embodiment, the angle between the length direction of the support rod 21 and the length direction of the guide member 30 is 12°~30° to ensure reliable support. Preferably, the angle between the length direction of the support rod 21 and the length direction of the guide member 30 is 15°, so as to reduce the footprint of the lifting fixture while ensuring reliable support and facilitating construction.

[0034] Specifically, one end of the support rod 21 along its length is connected to the outer wall of the guide member 30, and the support member 20 and the guide member 30 can be welded together. The other end of the support member 20 along its length contacts the ground, thus providing support for the guide member 30 and ensuring that the support member 40 slides reliably within the guide channel 31. Preferably, the support rod 21 has a hollow structure to reduce the weight of the support assembly and facilitate handling.

[0035] Furthermore, in a preferred embodiment, the number of support rods 21 is greater than or equal to 3. Three or more support rods 21 are arranged circumferentially around the guide member 30, so that two adjacent support rods 21 form a triangle with the ground, thereby improving the support reliability of the support member 20. Furthermore, such as Figure 1 As shown, the support member 20 also includes a first connecting rod 22. The first connecting rod 22 is formed into a strip-shaped rod structure and is disposed at the bottom of the support member 20. Both ends of the first connecting rod 22 in the length direction are connected to two adjacent support rods 21 respectively, thereby fixing the distance between the two adjacent support rods 21 and forming a triangular structure with the two support rods 21 and the first connecting rod 22, thus improving the reliability of the support. Preferably, the first connecting rod 22 is in contact with the ground, thereby increasing the contact area between the support member 20 and the ground and improving the reliability of the support.

[0036] It should be noted that in this embodiment, the deck that can abut against the support member is the bottom of the upper deck, and the ground that contacts the support member 20 is actually the top of the lower deck.

[0037] Furthermore, such as Figure 1As shown, the support member 20 also includes a second connecting rod 23 disposed above the first connecting rod 22. The second connecting rod 23 is formed into a rod-shaped structure. The two ends of the second connecting rod 23 in the length direction are respectively connected to the support rod 21 and the guide member 30, so that the second connecting rod 23, the support rod 21 and the guide member 30 form a triangular structure. The second connecting rod 23 is set at an angle to the first connecting rod 22, which further improves the support reliability of the support member 20 and avoids bending, collapse and other situations of the support member 40, thereby ensuring construction safety.

[0038] In this embodiment, the second connecting rod 23 is positioned at the middle of the support member 20 and connected to the bottom of the guide member 30, such that the length of the second connecting rod 23 is less than the length of the first connecting rod 22. The end of the support rod 21 away from the ground is positioned above the second connecting rod 23.

[0039] The number of first connecting rods 22 and support rods 21 is the same, and the number of second connecting rods 23 and support rods 21 is the same.

[0040] In this embodiment, as Figure 1 As shown, the support member 20 has an internal accommodating space 201, which is formed by the support rod 21, the first connecting rod 22 and the second connecting rod 23. The lifting member 10 is installed in the accommodating space 201 and is detachably connected to the support member 20. In this way, the lifting member 10, the support assembly and the load-bearing member can be transported separately, reducing weight and making transportation convenient. In a preferred embodiment, the length of the guide member 30 is L1 (mm); the reciprocating travel of the lifting end 11 is L2 (mm); and the length of the support member 40 is L3 (mm). 2×L2≤L1≤L3 ensures that within the reciprocating travel range of the lifting end 11, the support member 40 and the guide member 30 have sufficient overlap area, thereby ensuring reliable guidance of the guide member 30, preventing the support member 40 from detaching from the guide channel 31, and thus ensuring the safety of the lifting fixture.

[0041] Furthermore, in preferred embodiments, such as Figure 1 As shown, the deck height correction lifting fixture also includes rollers 50, which are mounted on the support member 20. When the guide channel 31 extends vertically, the rollers 50 do not contact the ground, allowing the bottom of the support component of the lifting fixture to be in contact with the ground during use, preventing the support component from tilting and ensuring stable support. After the lifting fixture is used, the guide channel 31 can be tilted so that the outer surface of the rollers 50 contacts the ground, thereby using the rollers 50 to move the lifting fixture to other locations. During the transportation process, the part of the guide member 30 protruding from the support member 20 can serve as a handle for workers to grip, further facilitating the transportation of the lifting fixture.

[0042] Specifically, the number of rollers 50 is set to two. The two rollers 50 can be installed on two different and adjacent support rods 21 respectively. In this way, during transportation, the side of the support assembly without rollers 50 can be tilted up so that the rollers 50 come into contact with the ground. This reduces the vertical height of the lifting fixture, making it easier for workers to hold the part of the guide 30 that protrudes from the support 20 and move the lifting fixture.

[0043] It should be noted that, in this embodiment, the support member 40 can abut against the beams or structural steel on the deck.

[0044] The deck height correction and lifting fixture of the present invention includes a lifting member with a reciprocating lifting end, a support assembly, and a support member. The support assembly includes a support member and a guide member mounted on the support member. A guide channel is formed inside the guide member, and the lifting end can extend into the guide channel. One end of the support member is disposed inside the guide channel, and the other end extends out of the guide channel and can abut against the bottom of the deck, thereby lifting the recessed upper deck. The lifting end abuts against the support member to drive the support member to slide along the guide channel, thereby assisting in adjusting the deck height between the upper and lower decks. It can be adjusted according to the deck height to meet different working conditions and improve the efficiency and accuracy of deck height repair. The support member and the guide member can support and guide the sliding of the support member to prevent the support member from collapsing, reduce safety hazards during the deck height repair process, and improve construction efficiency and safety.

[0045] According to a second aspect of the present invention, a ship includes the deck height correction jacking fixture as described above. Ships constructed using the deck height correction jacking fixture can have both construction efficiency and construction safety effectively improved.

[0046] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto.
