Abstract
Description
Technical Field
[0001] This utility model relates to the field of transport ships, and in particular to an adjustable support fixture for height-adjustable LNG transport ships. Background Technology
[0002] Liquefied natural gas (LNG) is primarily composed of methane. To facilitate transportation, it is typically liquefied by cryogenic freezing at atmospheric pressure. LNG carriers are specialized vessels developed for this purpose. An LNG carrier, short for Liquefied Natural Gas Carrier, is a ship specifically designed for transporting liquefied natural gas at extremely low temperatures (approximately -163°C). These vessels are characterized by high technology, high added value, and high reliability, playing a crucial role in the global energy supply chain.
[0003] Ship section assembly is a key step in the shipbuilding process. By assembling multiple prefabricated sections outside the slipway or dry dock to form larger sections or modules, and then hoisting them onto the hull for assembly, construction efficiency is significantly improved, costs are reduced, and quality control is optimized.
[0004] Support fixtures are one of the tools needed in the process of assembling ship sections. Currently, most shipyards use tubular supports with adjustable jacks at the bottom. However, tubular supports are unstable, inconvenient to install and require the use of cranes. Disassembly also requires crane assistance, increasing the use of heavy equipment, resulting in wasted labor and equipment costs, and reducing production efficiency. At the same time, due to the strength limitations of the tubular tube, the load of tubular supports is generally below 50 tons. When using them, more support points need to be arranged, increasing the work of welding support points. This also brings more burn damage to the hull painting and brings additional work for subsequent painting touch-ups. Utility Model Content

[0069] A forklift handling hole frame 7 is provided at a position of 1200mm from the supporting fixture. The forklift handling hole frame 7 is 250mm long and 150mm high to facilitate forklift handling.
[0070] In this technical solution, the supporting fixture is highly stable, easy to transport and store, and provides a higher level of operational safety. Simultaneously, this supporting fixture can be used as a construction platform to perform other construction operations within a certain range, improving its utilization efficiency. Furthermore, the supporting fixture has a simple structure, is easy to manufacture, and can be adjusted according to the lifting position of sections of different sizes and shapes, offering high flexibility. It features convenient installation, stable support, strong load-bearing capacity, and adjustable height, ensuring that the assembly of LNG carrier sections can be carried out quickly, efficiently, and safely.
[0071] The main components of this support fixture are made of Q235 steel, and its safe load-bearing capacity is 120 tons.
[0072] The support base 2 includes a support frame 21, and a lower wire mesh plate 22 is connected to the upper inner side of the support frame 21. The top surface of the support frame 21 and the top surface of the lower wire mesh plate 22 are on the same horizontal plane.
[0073] In this technical solution, the support base 2 can provide stable support for the structure of the support body 1.
[0074] Multiple reinforcing plates 23 are connected to the outside of the support frame 21.
[0075] In this technical solution, the structural strength of the support frame 21 can be increased by using the reinforcing plate 23.
[0076] The control component 4 includes a screw jack 41 and a spherical bearing 42. The bottom end of the screw jack 41 is connected to the top of the support body 1, and the top end of the screw lifting column of the screw jack 41 is connected to the bottom surface of the top support panel 3 by a spherical bearing 42.
[0077] In this technical solution, the height of the support fixture can be adjusted by adjusting component 4.
[0078] The top support panel 3 can be tilted up to 20 degrees by means of the spherical bearing 42, so as to adjust the appropriate angle according to the angle of the lifting block at the outer plate of the ship.
[0079] The effective stroke of the screw jack 41 is 0-200mm, which is adjusted by mechanical screw. The bottom of the screw jack 41 is connected to the top of the support body 1 by welding.
[0080] The working ladder 5 is composed of multiple ladder columns, and the distance between adjacent ladder columns is 250mm.
[0081] In this technical solution, the working ladder 5 facilitates climbing by workers.
[0082] The working platform 6 includes a fixed frame 61, and multiple upper wire mesh plates 62 are connected to the upper inner side of the fixed frame 61. The top surface of the fixed frame 61 and the top surface of the upper wire mesh plates 62 are on the same horizontal plane.
[0083] In this technical solution, construction work can be carried out on the work platform 6.
[0084] The top of the fixed frame 61 is connected to a safety fence 63.
[0085] In this technical solution, the safety fence 63 can ensure the safety of workers.
[0086] A working platform 6 is designed at a position 1700mm from the supporting fixture.
[0087] The height of the safety fence 63 is 600mm.
[0088] Multiple reinforcing elbows 8 are connected between the side of the supporting body 1 and the supporting frame 21;
[0089] Multiple reinforcing elbow plates 9 are connected to the side of the supporting body 1 and the bottom of the fixed frame 61;
[0090] Multiple reinforcing elbow plates 10 are connected to the side of the support body 1 and the bottom of the forklift handling hole frame 7;
[0091] The reinforcing elbow plate 1 (8), reinforcing elbow plate 2 (9), and reinforcing elbow plate 3 (10) are all triangular structures.
[0092] In this technical solution, the strength and stability of the supporting fixture can be increased by using reinforced elbow plate 1 (8), reinforced elbow plate 2 (9), and reinforced elbow plate 3 (10).
[0093] In use, the forklift uses the forklift transport frame 7 to transfer the support fixture to the area below the designated support position on the ship. Then, the workers climb up the working ladder 5 to the fixed frame 61 and the upper wire mesh plate 62, and then control the screw jack 41 to adjust the height of the top support panel 3.
[0094] After the support fixture is manufactured, the structural accuracy needs to be measured and the positions of the lifting rod that exceed the tolerance requirements need to be corrected. Each weld should be subjected to 100% magnetic particle testing 48 hours after welding. Fully penetrated welds need to be subjected to 100% magnetic particle testing and ultrasonic testing.
[0095] After completion, the entire surface is sanded, coated with one coat of workshop primer, and then coated with one coat of yellow topcoat. The service life is ten years.
[0096] After use, it should be stored in a special place and should be regularly inspected for appearance and flaw detection in order to be ready for the next use.
[0097] This support fixture is 2.5 meters long and 2.5 meters wide at the bottom, which greatly improves its stability compared to ordinary support fixtures. At the same time, it can be installed and dismantled with the help of a forklift, without the need for a large crane, which greatly reduces the requirements for the site. This makes the support fixture easy to install, stable in the support condition, and less restricted by the working space during installation and dismantling.
[0098] This support fixture has an allowable load of 120 tons, which is a significant improvement compared to the 50-ton allowable load of general support fixtures. This greatly reduces the number of support points in use, reduces the manufacturing and installation costs of the support caps, and reduces damage to the ship's paint. At the same time, the effective stroke of the spiral lifting column is 0-200mm, which is a significant improvement compared to the 0-100mm adjustable range of other shipyards. This makes the support fixture have the characteristics of strong load-bearing capacity and a wide range of height adjustment.
[0099] This support fixture only requires a forklift for installation, which is highly efficient and saves on labor and equipment costs. Using this support fixture ensures that the sectional assembly support work can be carried out quickly, efficiently, and safely.
[0100] An operating platform 16 is provided on the side of the support body 1, and the operating platform 16 is rotatably connected to the side of the support body 1 via a rotating component 12;
[0101] An adjustable support plate 13 is provided on the side of the operating platform 16 near the supporting body 1. The upper end of the adjustable support plate 13 is movably connected to the control component 14, and the lower end of the adjustable support plate 13 is movably connected to one side of the operating platform 16 through the connecting component 15.
[0102] In this technical solution, the worktable 16 can be used to place the tools used by the workers, making the work more convenient.
[0103] The control component 14 includes a rotating shaft 141. The upper end of the adjusting support plate 13 is connected to the rotating shaft 141. Both ends of the rotating shaft 141 are rotatably connected to the mounting plate 142. One side of the mounting plate 142 is connected to the side of the support body 1. One end of the rotating shaft 141 is connected to the output end of the control power source 143. The control power source 143 is connected to one side of the mounting plate 142.
[0104] In this technical solution, the control component 14 can drive the adjusting support plate 13 to rotate, so that the adjusting support plate 13 can drive the operating platform 16 to rotate, so that the operating platform 16 has a horizontal use state and a vertical storage state, preventing the structure of the operating platform 16 from affecting the movement of the workers on the work platform 6.
[0105] A fall arrestor 11 is provided on one side of the working ladder 5, and the side of the fall arrestor 11 is connected to the side of the supporting body 1.
[0106] The fall arrestor 11 protects workers moving on the working ladder 5, making it safer for workers to climb the working ladder 5.
[0107] The rotating assembly 12 includes a rotating block 121 and a positioning shaft 122. The surface of the positioning shaft 122 is rotatably connected to the rotating block 121. The bottom of the rotating block 121 is connected to the top of the operating table 16. Positioning side plates 123 are connected to both ends of the positioning shaft 122. One side of the positioning side plate 123 is connected to the side of the supporting body 1.
[0108] The connecting assembly 15 includes a rotating block 151 and a fixed shaft 152. The surface of the fixed shaft 152 is rotatably connected to the rotating block 151. The top of the rotating block 151 is connected to the bottom of the adjusting support plate 13.
[0109] Both ends of the fixed shaft 152 are connected to connecting plates 153. One side of the connecting plate 153 is connected to one side of the movable plate 154. The movable plate 154 is slidably connected to the surface of the guide rail 155. Both ends of the guide rail 155 are connected to limiting plates 156. One side of the limiting plate 156 is connected to one side of the operating table 16.
[0110] Multiple guide rails 155 are connected between the two limiting plates 156, and the multiple guide rails 155 are slidably connected through the movable plate 154.
[0111] In use, the control power source 143 drives the rotating shaft 141 to rotate, thereby driving the adjusting support plate 13 to rotate. The rotation of the adjusting support plate 13 drives the rotating block 151 to rotate around the fixed shaft 152, which in turn drives the connecting plate 153 to move. At this time, the movable plate 154 moves in the same direction along the guide rail 155.
[0112] When the movable plate 154 moves in the same direction as the guide rail 155, it also drives the guide rail 155, the limit plate 156 and one end of the operating plate 16 to rotate, so that the operating plate 16 rotates around the rotating block 121 and the positioning axis 122, thereby adjusting the angle of the operating plate 16 and changing the operating plate 16 from a vertical state to a horizontal state. At this time, the operating plate 16 can be used to place tools and other items of the staff.
[0113] When not in use, the operating platform 16 is changed from a horizontal state to a vertical state by using the opposite method to avoid the operating platform 16 affecting the movement of the workers on the work platform 6.
[0114] The control power source 143 is a motor set or other equipment that can output rotational kinetic energy.
