Description

Technical Field

[0001] This utility model relates to the field of shipbuilding, and in particular to an auxiliary adjustment structure for butt joints used in the assembly and construction of oil tankers. Background Technology

[0002] Product tankers, as liquid cargo ships specifically designed to transport refined petroleum products such as gasoline, diesel, and kerosene, are a subcategory of oil tankers. Their primary function is to deliver finished products from refineries to consumer markets, clearly distinguishing them from crude oil tankers that transport unprocessed crude oil.

[0003] Aframax tankers are economical tankers for short-haul transportation, with a deadweight tonnage between 80,000 and 120,000 tons. They offer high economic efficiency and flexibility, and their moderate size and draft allow them to navigate in relatively shallow waters, making them one of the ideal vessel types for navigation in the Bering Sea ice zone. By focusing on crude oil tanker construction technology, companies can improve their construction technology for very large crude carriers (VLCCs), accumulating experience for building a modern, intelligent, and green world-class shipbuilding and marine engineering equipment manufacturing industrial base.

[0004] In the assembly operations such as section fabrication and final assembly during shipbuilding, gaps are prone to appear at the joints of plates. These gaps need to be treated to ensure the stability of the ship. Currently, the method of adjusting misalignment of the joints is to use a jack. The jack assembly method involves welding the jack to fix the misalignment of the joints during assembly operations. First, the jack is welded, then the jack bolts are used to level it, then U-shaped plates are welded to fix it, and finally the jack is removed. Using the above method, the operation is cumbersome, time-consuming, has many flaws, and requires a large amount of welding and grinding during assembly. Utility Model Content

[0061] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0062] Figures 1 to 9 The diagram shown is a schematic representation of an embodiment of the auxiliary adjustment structure for the butt joint of the present invention for the assembly and construction of a finished oil tanker.

[0063] Example 1

[0064] like Figures 1 to 4 As shown, the auxiliary adjustment structure for the butt joint of the finished oil tanker assembly construction includes a mast plate 1 and a wedge 2. The mast plate 1 is fixed to the lower plate 3 by welding, and the wedge 2 is fixed to the upper plate 4 by welding.

[0065] One side of the horse plate 1 is in contact with one side of the wedge 2.

[0066] In this technical solution, the combined use of the mounting plate 1 and the wedge 2 greatly improves the efficiency of assembly operations, reduces the workload of assembly welding and grinding, and saves costs.

[0067] The cross-section of the horse plate 1 is a Z-shaped structure.

[0068] The cross-section of the wedge 2 is a triangular structure.

[0069] In use, weld and fix the horse plate 1 to one end of the lower plate 3 where the joint is lower. Then, insert the angled iron 2 from the higher plate 4 where the joint is higher into the position between the higher plate 4 and the iron 2. Then, use a sledgehammer to strike the iron 2 to insert it, so that the horse plate 1 and the iron 2 are horizontal, thus completing the joint adjustment.

[0070] Compared to the assembly of puller wedges, it reduces the need for welding pullers, removing pullers, and removing the pullers, thus reducing the workload of assembly welding and grinding.

[0071] It can be applied to the ship section splicing stage to adjust the misalignment of the plates to achieve a horizontal position. This method can be used for assembly operations, including internal material connection and structural connection.

[0072] Example 2

[0073] As one embodiment of this application, such as Figure 6 As shown, the difference between this and Embodiment 1 is that a fixing plate 5 is fixed to the low plate 3 by welding, and the fixing plate 5 has an L-shaped cross-section.

[0074] Example 3

[0075] As one embodiment of this application, such as Figure 5 As shown, its difference from other embodiments is that the horse plate 1 has multiple communication ports 6.

[0076] In this technical solution, the connecting port 6 can reduce the weight of the board 1 and make it easier to pick up the board 1.

[0077] The usage of connector 6 is the same as that of board 1.

[0078] Example 4

[0079] As one embodiment of this application, such as Figures 7 to 9 As shown, the difference between it and other embodiments is that a gap connecting plate 7 is provided above the gap between the low plate 3 and the high plate 4, a fixed base 8 is provided on one side of the gap connecting plate 7, and a lifting component 9 is provided on the other side of the gap connecting plate 7. The fixed base 8 is provided on the upper part of the high plate 4, and the lifting component 9 is provided on the upper part of the low plate 3.

[0080] The top of the fixed base 8 is connected to a support frame 10, and a lifting device 11 is provided inside the support frame 10. The bottom of the lifting device 11 is connected to the top of the fixed base 8, and the top of the lifting device 11 is connected to a fixed frame 12.

[0081] Two symmetrically distributed support sliders 14 are provided above the fixed frame 12. The bottom of the support sliders 14 is connected to the moving component 13. The moving component 13 is installed on the inner wall of the fixed frame 12.

[0082] The support slider 14 is slidably connected to the adjusting component 15, and one end of the adjusting component 15 is connected to the lifting component 9.

[0083] In this technical solution, the lower plate 3 can be pulled by the lifting device 11 and the lifting component 9, so that the lower plate 3 and the upper plate 4 are at the same level, and then the gap is connected by the gap connecting plate 7.

[0084] The fixed base 8 includes a supporting base plate 81 and an electromagnetic block 82, wherein the electromagnetic block 82 is embedded in the bottom of the supporting base plate 81.

[0085] In this technical solution, the support frame 10 and lifting device 11 can be fixed on the upper side of the high plate 4 by means of the fixed base 8.

[0086] In use, the fixed base 8 is placed on the upper side of the high plate 4, and then the electromagnetic block 82 is energized, so that the electromagnetic block 82 is attracted to the upper side of the high plate 4, thereby completing the fixation of the fixed base 8 and the support frame 10 and other structures.

[0087] The lifting component 9 includes a mounting plate 91 and an electromagnet block 92, wherein the electromagnet block 92 is embedded in the bottom of the mounting plate 91.

[0088] The top of the mounting plate 91 is connected to a lifting column 93, and the top of the lifting column 93 is connected to a lifting plate 94.

[0089] In this technical solution, the lower plate 3 can be fixed by using the lifting component 9.

[0090] The movable component 13 includes a bidirectional threaded shaft 131, both ends of which are rotatably connected to the inner wall of the fixed frame 12, and both ends of the bidirectional threaded shaft 131 are connected to a rotating disk 132.

[0091] The surface of the bidirectional threaded shaft 131 is threaded with two symmetrically distributed movable plates 133, and the bottom of the movable plates 133 is connected to the bottom of the support slider 14.

[0092] The inner wall of the fixed frame 12 is connected to a plurality of fixed rails 134, and the surface of the fixed rails 134 is slidably connected to the movable plate 133.

[0093] In this technical solution, the distance between the two lifting components 9 can be adjusted by moving component 13, thereby changing the position of the lifting lower plate 3.

[0094] The adjusting assembly 15 includes an adjusting plate 151. Two symmetrically distributed follower slide columns 152 are connected to one side of the adjusting plate 151. The surface of the follower slide column 152 is slidably connected to the support slider 14. The end of the follower slide column 152 away from the adjusting plate 151 is connected to one side of the lifting plate 94.

[0095] A threaded sleeve 153 is rotatably connected to one side of the adjusting plate 151. The threaded sleeve 153 is threadedly connected to the surface of the one-way stud 154. One end of the one-way stud 154 is connected to one side of the support slider 14.

[0096] In this technical solution, the distance between the lifting component 9 and the support frame 10 can be adjusted by the adjusting component 15 to accommodate different gaps.

[0097] Guide plates 16 are connected to both sides of the fixed frame 12. Multiple guide rails 17 are connected to the inner wall of the top surface of the support frame 10 and the top of the support base plate 81. The surface of the guide rails 17 is slidably connected to the guide plates 16.

[0098] When the lifting device 11 moves the fixed frame 12, the fixed frame 12 moves the guide plate 16 in the same direction along the guide rail 17. The guide rail 17 limits the movement trajectory of the guide plate 16 and the fixed frame 12, making the fixed frame 12 and other structures more stable when moving.

[0099] After the fixed base 8 is fixed, rotate the threaded sleeve 153 to move it along the one-way stud 154, thereby driving the adjusting plate 151 to move in the same direction, which in turn drives the follower slide 152 to move in the same direction, thereby driving the lifting plate 94 and the mounting plate 91 and other structures to move in the same direction, adjusting the mounting plate 91 to above the low plate 3.

[0100] Then rotate the rotating disk 132, thereby driving the moving plates 133 on both sides to move in the same direction along the fixed track 134. At this time, the corresponding support slider 14 moves in the same direction, thereby driving the follower slide column 152 and other structures to move in the same direction, thereby driving the lifting plate 94 and the mounting plate 91 to move in the same direction, and adjusting the distance between the two mounting plates 91.

[0101] Then, the lifting device 11 is used to drive the fixed frame 12, the moving component 13, the support slider 14, the adjusting component 15 and the lifting plate 94 to move down, thereby driving the lifting column 93 to move in the same direction, and then driving the mounting plate 91 and the electromagnet block 92 to move down, so that the electromagnet block 92 is attached to the top of the low plate 3. Then, the electromagnet block 92 is energized, so that the electromagnet block 92 is fixed on the low plate 3.

[0102] Then, the lifting device 11 is used to move the fixed frame 12, the mounting plate 91 and the electromagnet block 92 upward, thereby moving the low plate 3 upward, so that the low plate 3 and the high plate 4 are in a horizontal state, completing the adjustment of the low plate 3 and the high plate 4. Then, the gap connecting plate 7 is welded to the top of the low plate 3 and the high plate 4 respectively.

[0103] Once completed, the fixed base 8 and other structures can be removed in the opposite manner.

[0104] The lifting device 11 is a jack, a hydraulic lifting cylinder, or other equipment with autonomous extension and retraction functions.
