Description

Technical Field

[0001] This utility model relates to the field of shipbuilding, specifically to a combined support structure for the main deck of a very large ethane carrier. Background Technology

[0002] Because there are many pipelines and valves on the deck of a very large ethane carrier, different types of supports and valve operating platforms need to be installed on the deck. This results in a large number of supports and operating platforms on the deck that are disorganized, reducing the limited walking space on the deck and affecting the safety of personnel walking on the deck.

[0003] Therefore, during the design phase, the piping system on large ethane carriers should be arranged in layers according to its characteristics, and corresponding pipe and channel combination supports should be designed. However, in the actual ship design and construction process, the outfitting specialist can only design the outfitting platform supports after the piping layout specialist has completed the piping layout. The two specialists are not working in sync, increasing the number of coordination issues, resulting in a longer design cycle and significantly increasing the difficulty of production design. Furthermore, after the supports are fabricated, secondary assembly is required, increasing construction difficulty and hoisting workload. Summary of the Invention

[0004] In order to achieve an orderly layout and effective support for pipes and cables on the main deck of a large ethane carrier, while not affecting passage on the deck and saving design and manufacturing costs, this utility model provides a combined support for the main deck of an ultra-large ethane carrier.

[0005] The technical solution adopted by this utility model is as follows: A modular support structure for the main deck of a very large ethane carrier includes a main frame. The main frame comprises support frame units evenly spaced along the length of the ship on the deck. Each support frame unit includes three vertical columns and a top beam. The bottoms of the three columns are fixedly welded to the deck, and the tops of the three columns are welded to the beam to form a portal frame. Multiple small beams distributed vertically are welded between adjacent columns, dividing adjacent columns into multiple support areas for supporting pipelines. Multiple cable frames are installed on the top of a row of support frame units. These cable frames extend parallel to the length of the ship and are welded and fixed to the top surface of the beams. A deck passage is provided on the top of the main frame. The deck passage includes multiple passage portal frames, which correspond to the beams. Two vertical support legs of the passage portal frames are welded and fixed to the top surface of the corresponding beams. Horizontal grids are installed between adjacent passage portal frames.

[0006] Furthermore, a locking structure that mates with the corresponding pipeline is installed on the small crossbeam. The locking structure is a U-shaped locking rod with external threads at both ends. The U-shaped locking rod is fitted onto the outside of the pipeline, and the end of the U-shaped locking rod passes through the small crossbeam. A pair of nuts are installed at each end of the U-shaped locking rod, and the pair of nuts are distributed on the upper and lower sides of the small crossbeam.

[0007] Furthermore, a support structure is installed on the small crossbeam corresponding to the cold pipe. The support structure includes a horizontal base, which is welded and fixed to the top surface of the small crossbeam. A vertical support plate is welded to the horizontal base, and ribs are welded to both sides of the vertical support plate. The bottom surface of the ribs is welded and reinforced to the horizontal base. The top of the ribs forms a semi-circular support part. A clamp is supported on the top of the vertical support plate. The clamp cooperates with the semi-circular support part formed by the ribs. The clamp is wrapped with an insulating sleeve.

[0008] Furthermore, the support structure also includes an extension plate, which is welded to both sides of the top surface of the small crossbeam in the width direction. The extension plate is reinforced by welding to the side of the small crossbeam through an elbow plate, and the horizontal base is located within the extension range of the plate.

[0009] Furthermore, railing posts are welded to both sides of the top of the channel gate frame. Each railing post has multiple railing crossbar holes from bottom to top. The tops of adjacent railing posts on the same side are connected by railing handrails, and crossbars pass through the railing crossbar holes of adjacent railing posts on the same side.

[0010] Furthermore, the cable frame is a double-layer or multi-layer cable frame.

[0011] Furthermore, the cable frame includes multiple frame units and shelves. Each frame unit includes a pair of vertical angle irons with multiple mounting holes on the sides. The shelves are fixed to each frame unit by limiting pins.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: a multi-layered composite frame for supporting pipes is formed on the deck through a row of support frame units and cable frames. The multi-layered frame facilitates the classified support of various pipes of different sizes, temperatures, and uses, and the multiple cable frames facilitate the orderly layout of different cables; the support of pipes and cables on the deck is designed synchronously, which can avoid secondary assembly during the ship construction process; a deck passage is set at the top of the composite frame to solve the problem of passage on the deck due to the arrangement of pipes.

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings: like Figure 1 As shown, the main deck modular support for a super-large ethane carrier is installed on the deck of the ship. It consists of a main frame and a deck passage on top of the main frame. It is used to provide limited classified support and fixation for various pipes, cables and other items on the deck, while also solving the problem of passage on the deck.

[0018] The main frame consists of support frame units 1 evenly spaced along the length of the ship on the deck, and cable frames 2 on top of the support frame units 1. Each support frame unit 1 is welded together from three vertical columns 11 and a top crossbeam 12. The bottoms of the three columns 11 are fixedly welded to the deck, and the tops of the three columns 11 are welded to the crossbeam 12 to form a portal frame. Multiple small crossbeams 13 are welded vertically between adjacent columns, dividing the adjacent columns into multiple support areas for supporting pipelines. Different areas are used to support different pipelines; generally, larger pipelines are supported in the lower areas, and smaller pipelines are supported in the upper areas.

[0019] The small crossbeam 13 is made of I-beam steel, and a locking structure 3 is installed on it to match the corresponding pipeline. The locking structure is generally a U-shaped locking rod, with external threads at both ends. The U-shaped locking rod is fitted onto the outside of the pipeline, and the end of the U-shaped locking rod passes through the small crossbeam and is locked by a nut. To improve the locking effect, a pair of nuts are installed at each end of the U-shaped locking rod, with the pair of nuts distributed on the upper and lower sides of the small crossbeam.

[0020] Since the ship is a gas transport vessel, cryogenic refrigeration pipes are involved. According to the requirements of ship design specifications, the refrigeration pipes need to have separate support seats to avoid the formation of cold bridges. A support structure is installed on the small crossbeam corresponding to the refrigeration pipe. The support structure includes a horizontal base 4, which is welded and fixed to the top surface of the small crossbeam 13. A vertical support plate 5 is welded to the horizontal base 4. Ribs 6 are welded to both sides of the vertical support plate 5. The bottom surface of the ribs 6 is welded and reinforced to the horizontal base 4. The top of the ribs 6 is an arc-shaped notch. The arc-shaped notches of the two ribs form a semi-circular support part for supporting the pipe. A clamp 7 is fixed to the top of the vertical support plate. The clamp 7 is wrapped with an insulating sleeve and is used to fix the refrigeration pipe. The semi-circular support part supports the clamp 7.

[0021] To avoid welding failure and welding stress caused by welding the edges of the horizontal base and the small crossbeam, extension plates 8 are horizontally extended outward on both sides of the width direction of the small crossbeam. The extension plates 8 are reinforced by welding the sides of the small crossbeam 13 with elbow plates 9. The horizontal base 4 is located within the extension range of the plates 8, and the four edges of the horizontal base 4 are surface welded to the top surface of the small crossbeam 13 or the extension plates 8.

[0022] Multiple cable frames 2 extend parallel to the length of the ship and are welded and fixed to the top surface of the crossbeams 12 of each support frame unit; the cable frame 2 is a double-layer or multi-layer cable frame. The cable frame consists of multiple sets of frame units and shelves. The frame unit includes a pair of vertical angle irons, which are welded to the top surface of the corresponding crossbeams. The angle irons have multiple mounting holes on their sides. The shelves are installed and fixed to each frame unit by limiting pins. The number of layers can be increased or decreased according to the cable laying requirements.

[0023] A deck passage 10 is provided at the top of the main frame. The deck passage includes multiple passage portal frames 14, which correspond to the crossbeams 12. The two vertical support legs of the passage portal frames 14 are welded and fixed to the top surface of the corresponding crossbeams 12. Horizontal grids 15 are installed between adjacent passage portal frames 14 for personnel to walk on. To improve safety, railing posts 16 are welded to both sides of the top of the passage portal frames. Each railing post 16 has multiple railing crossbar holes from bottom to top. The tops of adjacent railing posts on the same side are connected by railing handrails. Crossbars pass through the railing crossbar holes of adjacent railing posts 16 on the same side, forming an effective protection.
