Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a container ship anti-torsion box segment assembly device and its usage method. Background Technology

[0002] Because container ships are large-opening vessels, the main way to ensure the strength of the hull is by relying on the anti-torsion box structure on the side of the hull. The steel plates in this area are relatively thick, and the amount of welding material is large. Since the longitudinal structure here is divided into sections by ribs, automatic welding equipment cannot be used. Currently, manual electric welding by workers is used, which takes a long time and results in a large difference in welding quality. In addition, due to the large thickness of the plate, an additional heating plate is required, which makes the construction efficiency very low.

[0003] Furthermore, due to the large thickness of the plate, an additional heating plate is required to preheat the steel plate. During welding, the large heat input of the fillet weld between the base plate and the flat steel will cause the flat steel to twist and deform, resulting in the structural accuracy deviation after welding exceeding the standard. Summary of the Invention

[0004] In view of this, the present invention provides a container ship anti-torsion box segment assembly device and its usage method to solve the problems existing in the background art.

[0005] A container ship anti-torsion box segment assembly device includes a first baffle, a second baffle, a third baffle, a fourth baffle, a baffle support, and a crossbeam. The first and second baffles are vertically opposite each other to form a first gap between them, and the third and fourth baffles are vertically opposite each other to form a second gap between them. The baffle support is connected between the second and third baffles. The crossbeam is located on the top of the first, second, third, and fourth baffles and has multiple lifting lugs. The crossbeam is connected to the first and fourth baffles by a first support. When the container ship anti-torsion box segment assembly device is lifted onto the anti-torsion box segment, the flat steel of the anti-torsion box segment is precisely stuck in the first and second gaps, and the bottoms of the first, second, third, and fourth baffles do not contact their base plates, so that the fillet weld between the flat steel and the base plate can be continuously and unobstructed.

[0006] Preferably, a second support is also connected between the crossbeam and the first baffle and the fourth baffle, with one end of the second support fixed to the end of the crossbeam and the other end fixed to the upper end of the first baffle or the fourth baffle.

[0007] Preferably, one end of the first support is fixed to the end of the crossbeam, and the other end is fixed to the lower end of the first baffle or the fourth baffle.

[0008] Preferably, the transverse centerline of the crossbeam coincides with the transverse centerlines of the first baffle, the second baffle, the third baffle, and the fourth baffle.

[0009] Preferably, the heights of the first baffle, second baffle, third baffle, fourth baffle, and baffle support are equal and less than the height of the flat steel, and the straight-line distance between the second baffle and the third baffle is equal to the distance between the two flat steels on the anti-torsion box segment.

[0010] Preferably, four baffle supports are provided, wherein one side of two baffle supports is fixed to the two sides of the second baffle, and one side of the other two baffle supports is fixed to the two sides of the third baffle, and the other sides of the four baffle supports intersect and converge together.

[0011] A method for using a container ship anti-torsion box segment assembly device specifically includes the following steps:

[0012] S1. Place the base plate on the jig, then hoist two flat steel bars onto the base plate and temporarily fix them by intermittent spot welding at the fillet weld positions. Position the flat steel bars according to the positioning lines marked on the base plate.

[0013] S2, connect the hook of the lifting equipment to the lifting lug of the anti-torsion box segment assembly device of the container ship, and lift the anti-torsion box segment assembly device of the container ship onto the flat steel so that the two flat steels are just stuck in the first gap and the second gap. At this time, the bottom of the first baffle, the second baffle, the third baffle and the fourth baffle do not contact the bottom plate.

[0014] S3, Repeat step S2, hoist multiple container ship anti-torsion box segment assembly devices onto the flat steel;

[0015] S4, Use a fillet welder to continuously weld the fillet weld between the flat steel and the base plate;

[0016] S5. After welding is completed, remove all container ship anti-torsion box segment assembly devices and insert structural elbow plates and ribs.

[0017] The beneficial effects of this invention are:

[0018] 1. By making the height of the first baffle, second baffle, third baffle and fourth baffle lower than the height of the flat steel, when the present invention is hoisted on the flat steel of the anti-torsion box segment, the bottom of the first baffle, second baffle, third baffle and fourth baffle do not contact the base plate, so that the fillet weld between the flat steel and the base plate can be continuous and unobstructed, thereby providing welding space for automatic welding equipment and improving welding efficiency and welding quality.

[0019] 2. The size of the first gap and the second gap of the present invention is matched with the thickness of the flat steel. In this way, when the two flat steels of the anti-torsion box segment are stuck in the first gap and the second gap, the four baffles can provide lateral stability for the flat steel, avoid the flat steel from twisting and deforming randomly in the gap during fillet weld welding, avoid the structural accuracy deviation after welding from exceeding the standard, and improve the welding quality.

[0034] The first baffle 23 and the second baffle 24 are vertically opposite each other to form a first gap 3 between them. The third baffle 26 and the fourth baffle 27 are vertically opposite each other to form a second gap 4 between them. The first gap 3 and the second gap 4 are used to clamp the flat steel 2 of the anti-torsion box segment.

[0035] The baffle support 25 is connected between the second baffle 24 and the third baffle 26 and is used to support the baffle. In this embodiment, four baffle supports 25 are provided, wherein one side of two baffle supports is fixed to the two sides of the second baffle 24 respectively, one side of the other two baffle supports is fixed to the two sides of the third baffle 26 respectively, and the other sides of the four baffle supports intersect and converge together.

[0036] The crossbeam 22 is positioned on top of the first baffle 23, the second baffle 24, the third baffle 26, and the fourth baffle 27, which improves the lateral structural strength of the entire device and ensures its overall rigidity. The lateral centerline of the crossbeam 22 coincides with the lateral centerlines of the first baffle 23, the second baffle 24, the third baffle 26, and the fourth baffle 27. Multiple lifting lugs 21 are provided on the crossbeam 22. A first support 28 connects the crossbeam 22 to the first baffle 23 and the fourth baffle 27.

In this way, when the two flat steels 2 of the anti-torsion box segment are stuck in the first gap 3 and the second gap 4, the four baffles can provide lateral stability for the flat steel 2, avoid the flat steel 2 from twisting and deforming at will in the gap during fillet weld welding, and avoid the structural accuracy deviation after welding from exceeding the standard.
