Description

Technical Field

[0001] This application relates to the field of shipbuilding technology, and in particular to a high-altitude assisted turning and hoisting tooling and equipment module turning and hoisting process. Background Technology

[0002] For a certain type of vessel currently under construction, the manufacturing cycle for key equipment modules is long and delivery is late. The modules are irregularly shaped, making it impossible to perform normal hoisting into the pre-drilled installation area for assembly after the hull has been flipped over. After the entire hull is assembled, various external factors such as support frames and scaffolding prevent normal hoisting operations from the bottom up (using the dock surface as a reference point) through the hull openings. This severely impacts the docking time for hull assembly and the target indicators for vessel launch integrity. Summary of the Invention

[0003] To address the aforementioned issues, this application proposes a high-altitude assisted turning and lifting tooling and equipment module turning and lifting process by studying the structural characteristics of this type of ship, the lifting resources at the equipment installation location, and the lifting height requirements at the lifting points.

[0004] In a first aspect, embodiments of this application provide a high-altitude assisted turning and hoisting fixture, the fixture comprising: two gantry support frames;

[0005] The portal frame includes a crossbeam and two legs supporting both ends of the crossbeam. The crossbeam is fitted with at least two snap-on gantry cranes, which are capable of moving along the axial direction of the crossbeam.

[0006] The portal frame can be installed across the hull opening on the hull deck, and the crossbeam at least partially corresponds to the hull opening.

[0007] In some alternative embodiments, anti-tipping braces are provided on both sides of the outriggers to abut against the hull deck when the portal frame is installed on the hull deck, so as to support the outriggers.

[0008] In some alternative embodiments, the anti-tipping brace includes an anti-tipping brace circular tube.

[0009] In some alternative embodiments, the outer diameter of the anti-tipping brace tube is 159 mm and the wall thickness is 10 mm.

[0010] In some alternative implementations, the number of snap-on gantry cranes is eight, and the eight snap-on gantry cranes are evenly or unevenly distributed on the two portal support frames.

[0011] In some alternative implementations, the load-bearing capacity of a single snap-on crane is 30 tons.

[0012] Secondly, embodiments of this application provide a method for hoisting and turning over equipment modules, employing the high-altitude assisted turning and hoisting fixture described in any embodiment of the first aspect above. The method includes the following steps:

[0013] Step S1: Attach the crane wire rope to the first end hoist on the upper surface of the equipment module, use the crane to lift the equipment module above the hull opening, and then lift the equipment module into the hull opening. The descent speed is less than the preset speed. Stop the descent when the equipment module is lifted to a position at a first preset height above the dock ground.

[0014] Step S2: The second end of the surface of the equipment module is attached to the snap-on hoist of a portal support frame of the tooling via the first steel wire rope. The crane and the tooling are then used to complete the turning operation of the equipment module.

[0015] Step S3: After the equipment module has been turned over, the first end of the equipment module is hooked to the snap-on hook of another portal support frame of the tooling via the second wire rope, and the unhooking operation of the crane is completed.

[0016] Step S4: After the crane is moved, the tooling is used to lift the equipment module at a constant speed and smoothly to the second preset height of the hull to fill the opening of the hull, thus completing the aerial flipping and installation of the equipment module.

[0017] The beneficial effects of the technical solution in this application are as follows:

[0018] The embodiments described above in this application successfully solved the problem of high-altitude assisted turning and hoisting of equipment modules by designing a high-altitude assisted turning and hoisting tooling and a process method for equipment module turning and hoisting. This shortened the docking period and improved the integrity of the ship's launch. It also solved the problem of large-area interference between bottom-up hoisting of equipment modules and supporting tooling and scaffolding, as well as a large amount of redundant work such as structural cutting, modification, and patching, significantly reducing labor intensity and costs. Furthermore, it reduced the extensive use of scaffolding in traditional high-altitude turning and hoisting operations, resulting in significant improvements in quality and efficiency. The technical solution of this application has been successfully applied in practice, using this tooling in conjunction with a crane to smoothly complete the high-altitude turning and hoisting of equipment weighing approximately 40 tons at a height of about 16 meters above the dock floor. This effectively shortened the docking period for this type of ship and ensured the target indicator of the integrity of the ship's launch. Attached Figure Description

[0028] Figure 1 This is a partial structural side view of a high-altitude assisted turning and hoisting tool according to an embodiment of this application. Figure 2 This is a partial front view of a high-altitude assisted turning and hoisting fixture according to an embodiment of this application. This application embodiment provides a high-altitude assisted turning and hoisting fixture, such as... Figure 1 and Figure 2 As shown, the high-altitude assisted turning and hoisting fixture may include two gantry support frames 11. It should be noted that the two gantry support frames 11 in the high-altitude assisted turning and hoisting fixture of this application embodiment have the same structure, therefore... Figure 1 and Figure 2 Each of the 11 models features a single portal frame support.

[0029] The portal frame 11 includes a crossbeam 13 and two legs 14 supporting both ends of the crossbeam 13. The crossbeam 13 is fitted with at least two snap-on gantry cranes 12, which can move axially along the crossbeam 13.

[0030] like Figure 2 As shown, the portal frame 11 can be installed on the hull deck 21 across the hull opening 22, and the crossbeam at least partially corresponds to the hull opening 22.

[0031] Here, the load-bearing capacity of a single snap-on crane 12 is 30 tons. The crossbeams 13 and legs 14 of the gantry support frame 11 can be made of steel plates with a thickness of 15 mm or more.

[0032] In some alternative embodiments, the number of snap-on hoisting horses 12 in the high-altitude assisted turning and hoisting fixture is eight, and the eight snap-on hoisting horses 12 can be evenly or unevenly distributed on the two portal support frames 11. For example, each of the two portal support frames 11 is provided with four snap-on hoisting horses 12; or, one portal support frame 11 is provided with three snap-on hoisting horses 12 and the other portal support frame is provided with five snap-on hoisting horses 12; or, one portal support frame 11 is provided with two snap-on hoisting horses 12 and the other portal support frame is provided with six snap-on hoisting horses 12.

[0033] In some alternative implementations, the total number of snap-on gantry cranes 12 can be set according to the needs of the equipment being hoisted. For example, the number of snap-on gantry cranes 12 installed on the two portal support frames 11 can be adjusted to correspond to the number of gantry cranes at both ends of the equipment.

[0034] Figures 3 to 7 This is a schematic diagram illustrating the construction process of a method for hoisting and turning over an equipment module according to an embodiment of this application. This application provides a method for hoisting and turning over an equipment module, employing high-altitude auxiliary turning and hoisting fixtures as described in any of the above embodiments. The construction process is as follows: Figures 3 to 7 As shown, the process for hoisting and turning over the equipment module includes the following steps:

[0035] Step S1, as follows Figure 3 As shown, the crane wire rope 25 is attached to the first end of the upper surface of the equipment module 24. The crane 23 is used to lift the equipment module 24 above the hull opening 22. Then the equipment module 24 is lifted into the hull opening 22. The descent speed is less than the preset speed. The descent stops when the equipment module 24 is lifted to a position 28 above the dock floor.

[0036] Here, the hull opening 22 can be an opening for embedding and installing the equipment module 24. The first preset height can be, for example, any height that allows the equipment module 24 to avoid touching the lower surface of the hull opening 22 during the overturning operation, while facilitating operation by construction personnel. For example, the first preset height can be, for example, 3 meters.

[0037] In this embodiment, the crane 23 is a single crane.

[0038] Step S2, as follows Figure 3 As shown, the second end of the surface of the equipment module 24 is hooked to the snap-on hook 12 of a portal support frame 11 of the tooling via the first wire rope 26, and the crane 23 is used in conjunction with the tooling to complete the turning operation of the equipment module 24.

[0039] The first wire rope 26 can be pre-installed on the second end hoist on the surface of the equipment module 24, or it can be pre-installed on the snap-on hoist 12 of the gantry support frame 11.

[0040] Here, as Figure 3 As shown, anti-tipping braces 15 are provided on both sides of the outriggers, which are used to abut against the hull deck 21 when the portal frame 11 is installed on the hull deck 21 to support the outriggers 14. Here, the anti-tipping braces 15 may include, for example, an anti-tipping brace tube. The anti-tipping brace tube may be a tube with an outer diameter of 159 mm and a wall thickness of 10 mm. The anti-tipping braces 15 are used to prevent the portal frame 11 of the tooling from tipping over due to excessive force when the hoisted equipment module 22 is turned over.

[0041] Step S3, as follows Figure 4 and Figure 5 As shown, after the equipment module 24 has been turned over, the first end of the surface of the equipment module 24 is hooked to the snap-on hook 12 of another portal support frame 11 of the tooling via the second wire rope 27, and the unhooking operation of the crane 23 is completed.

[0042] The second wire rope 27 can be pre-installed on the second end hoist on the surface of the equipment module 24, or it can be pre-installed on the snap-on hoist 12 of the gantry support frame 11.

[0043] For example, in some embodiments, two hoists are respectively provided at both ends of the upper surface of the device module 24, namely the first end and the second end. The two hoists at the second end can be connected to the wire rope 25 of the crane in step S1. At this time, when the crane 23 pulls and lifts the device module 23, the upper surface of the device module 23 is subjected to force at one end, and is in a state of... Figure 3The side-tilting state is shown; in step S2, the two hoists at the first end can be hooked to the two snap-on hoists 12 of a portal support frame 11 of the tooling by the first wire rope 26, so as to hook the four hoists on the upper surface of the equipment module 24. The height of the two ends of the upper surface of the equipment module 24 can be adjusted by the cooperation of the crane 23 and the tooling, so as to realize the overturning operation of the equipment module 24.

[0044] Step S4, as follows Figure 6 and Figure 7 As shown, after the crane 23 is moved, the equipment module 24 is lifted at a constant speed and smoothly to the second preset height of the hull to fill the hull opening 22, thus completing the aerial flipping and installation of the equipment module 24.

[0045] Here, the second preset height may be, for example, the height corresponding to the design and installation position of the device module 24.

[0046] It should be noted that before hoisting equipment module 22, all unused materials on the deck surface in the equipment hoisting area should be cleared, and safety railings and warning zones should be set up in the equipment hull opening 22 area to ensure construction safety. After the high-altitude auxiliary turning and hoisting fixtures are installed and fixed, a single crane will be used to complete the high-altitude turning and hoisting installation of the equipment module.

[0047] The embodiments described above in this application successfully solved the problem of high-altitude assisted turning and hoisting of equipment modules by designing a high-altitude assisted turning and hoisting tooling and a process method for equipment module turning and hoisting. This shortened the docking period and improved the integrity of the ship's launch. It also solved the problem of large-area interference between bottom-up hoisting of equipment modules and supporting tooling and scaffolding, as well as a large amount of redundant work such as structural cutting, modification, and patching, significantly reducing labor intensity and costs. Furthermore, it reduced the extensive use of scaffolding in traditional high-altitude turning and hoisting operations, resulting in significant improvements in quality and efficiency. The technical solution of this application has been successfully applied in practice, using this tooling in conjunction with a crane to smoothly complete the high-altitude turning and hoisting of equipment weighing approximately 40 tons at a height of about 16 meters above the dock floor. This effectively shortened the docking period for this type of ship and ensured the target indicator of the integrity of the ship's launch.

[0048] Prior to the implementation of this invention, no feasible solution had been found for using a single crane in conjunction with other equipment to perform aerial assisted turning operations on heavy equipment at high altitudes.
