Ship engine room paving assembly and installation method Technical Field
[0001] This invention relates to the field of shipbuilding equipment technology, and more specifically, to a ship engine room paving assembly and installation method. Background Technology
[0002] During shipbuilding, flooring is installed in the engine room to facilitate personnel monitoring, observation, operation of equipment, and control of valves; ensure personnel can access all parts of the engine room; meet the anti-slip requirements in the specifications; and temporarily place small equipment (such as water pumps, small axial flow fans, and high-intensity lights) during equipment debugging or maintenance.
[0003] Typically, the connections between the scaffolding structures are achieved through welding. This welding process requires extensive grinding and generates significant environmental pollution. Some scaffolding components may interfere with the maintenance or disassembly of equipment in the nacelle. Because the scaffolding is installed using electric welding, the disassembly and reassembly of the scaffolding is extremely labor-intensive, wasting manpower and impacting work efficiency. Furthermore, the disassembly and reassembly process can easily damage parts of the scaffolding, leading to material waste. Technical solutions

[0059] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0060] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.
[0061] Please refer to Figure 1. This embodiment provides a ship engine room paving assembly, including a frame device 12 and a paving panel 13.
[0062] The frame device 12 includes a reinforcing plate 2, a support 3, a straight section 5, and a horizontal section 9 or a column 8;
[0063] Along the length of the support 3, one end of the support 3 is connected to the inner bottom plate 1 or bulkhead of the cabin; the other end of the support 3 is connected to the straight bar 5; there is an angle between the support 3 and the straight bar 5; the straight bar 5 can be detachably connected to the column 8 or the crossbar 9; there is an angle between the straight bar 5 and the column 8, or between the straight bar 5 and the crossbar 9.
[0064] The slab 13 is detachably mounted on the frame device 12.
[0065] The frame device 12 of such ship engine room paving assembly has at least straight sections 5 that can be detachably connected to columns 8 or crossbars 9. This can greatly reduce the amount of welding and grinding work during the installation of the paving 13, reduce the environmental pollution during the installation process, and make installation and disassembly convenient. Repeated disassembly and assembly will not cause damage or waste to the grille.
[0066] It should be noted that reinforcing plate 2, support 3, straight bar 5, and horizontal bar 9 can be referred to as structural components. Reinforcing plate 2, support 3, straight bar 5, and horizontal bar 9 can all be made of angle steel. All structural components at the same height should be installed with the horizontal folded edges of the angle steel on the same plane. The angle steel around the structural device 12 and around the equipment should have its folded edges facing upwards; if this is difficult, flat steel should be welded instead.
[0067] Optionally, holes are made at corresponding positions on the paving plate 13 and the frame device 12, and cross-slot countersunk screws 11 are sequentially passed through the corresponding holes on the paving plate 13 and the frame device 12 to achieve a detachable connection between the paving plate 13 and the frame device 12.
[0068] In an optional embodiment, the support 3 is fixedly connected to the inner bottom plate 1; or the support 3 is detachably connected to the inner bottom plate 1 or the bulkhead by fasteners.
[0069] In an optional embodiment, a reinforcing plate 2 is provided between the support 3 and the inner floor plate 1; along the thickness direction of the reinforcing plate 2, one side of the reinforcing plate 2 is welded to the inner floor plate 1 or the bulkhead (the weld seam 7 is shown in the figure, which will not be described again below) and the other side of the reinforcing plate 2 is welded to the support 3. Specifically, a reinforcing plate 2 is provided on the inner floor plate 1 or the bulkhead, one side of the reinforcing plate 2 is welded to the inner floor plate 1 or the bulkhead, and the other side is welded to the support 3, as shown in Figures 1 and 2.
[0070] In an optional embodiment, the frame device 12 further includes an angle steel eye plate and a first fastener 4; the angle steel eye plate includes a drilled plate and a connecting plate connected to each other, with an included angle between the drilled plate and the connecting plate; the drilled plate has a plurality of drill holes.
[0071] When the support 3 has a mating hole 901; the first fastener 4 is sequentially passed through the connecting drill hole and the mating hole 901 so that the angle steel eye plate is connected to the support 3; the connecting plate is welded to the straight block 5 so that the support 3 and the straight block 5 can be detachably connected.
[0072] When the straight block 5 has a mating hole 901; the first fastener 4 is sequentially passed through the connecting drill hole and the mating hole 901 so that the angle steel eye plate is connected to the straight block 5; the connecting plate is welded to the column 8 so that the straight block 5 and the column 8 can be detachably connected.
[0073] When the crossbar 9 has a mating hole 901; the first fastener 4 is sequentially passed through the connecting drill hole and the mating hole 901 so that the angle steel eye plate is connected to the crossbar 9; the connecting plate is welded to the straight bar 5 so that the crossbar 9 and the straight bar 5 can be detachably connected.
[0074] Specifically, the support 3 and the straight block 5 are connected by an angle iron eyelet plate 6. First, one side of the angle iron eyelet plate 6 with a hole is connected to the support 3 using the first fastener 4. Then, the other side of the angle iron eyelet plate 6 is welded to the straight block 5, as shown in Figures 3, 4, and 5. The first fastener 4 consists of a fully threaded hexagonal head bolt and a double nut.
[0075] The straight block 5 and the column 8 are connected by an angle iron eyelet plate 6. The side of the angle iron eyelet plate 6 with holes is first connected to the straight block 5 using the first fastener 4, and the other side of the angle iron eyelet plate 6 is connected to the column 8 by welding as shown in Figure 6.
[0076] The straight block 5 and the column 8 are connected in parallel using two angle iron eyelets 6. First, one side of the first angle iron eyelet 6 is welded to the straight block 5. Then, the two angle iron eyelets 6 are connected by the first fastener 4. Finally, the other side of the second angle iron eyelet 6 is welded to the column 8 as shown in Figure 6.
[0077] The horizontal bar 9 and the vertical bar 5 are conventionally connected using fasteners. The thickness difference between the horizontal bar 9 and the vertical bar 5 is adjusted to a uniform height using the shoulder provided on the horizontal bar 9, as shown in Figures 12 and 13. In special cases, the horizontal bar 9 and the vertical bar 5 can also be connected using an angle iron eyelet plate 6, as shown in Figure 7. The fasteners here consist of Phillips head countersunk screws 11, flat washers, and spring washers.
[0078] In an optional embodiment, the straight block 5 has a folded edge in the width direction; when there are multiple straight blocks 5 in the frame device 12, the straight block 5 located in the middle part of the frame device 12 should have its folded edge facing down when it is installed, and the countersinking direction of the mating hole 901 is opposite to the direction of the folded edge. The countersinking hole at this time is called the outer countersinking hole 501, as shown in Figure 10.
[0079] When installing the straight blocks 5 located around the frame device 12, the folded edge should face upwards, and the countersinking direction of the mating hole 901 should be consistent with the folded edge direction. This countersinking is called the inner countersinking hole 502, as shown in Figure 11.
[0080] In an optional embodiment, shoulders are provided at both ends of the crossbar 9 along its length, and mating holes 901 are provided on the shoulders. The angle steel folds of the crossbar 9 located around the frame device 12 or adjacent to the equipment have their folded edges facing upwards, and the shoulders are in the opposite direction to the folded edges to form outer shoulders 902, as shown in Figure 8. The angle steel folds of the crossbar 9 located in the middle of the frame device 12 should face downwards, and the shoulders are in the same direction as the folded edges to form inner shoulders 903, as shown in Figure 9. In this way, shoulders are provided at both ends of the crossbar 9 so that the crossbar 9 is at the same height when installed on the straight bar 5.
[0081] Furthermore, the crossbar 9 needs to be preheated before bending the shoulder to reduce the difficulty of bending and avoid damage to the angle steel caused by cold bending.
[0082] In an optional embodiment, the height of the shoulder is the same as the thickness of the crossbar 9; the length of the shoulder is 13-17mm greater than the width of the crossbar 9. Preferably, the height of the shoulder is the same as the thickness of the angle iron, and the length of the shoulder should be the side length of the angle iron plus 15±2mm.
[0083] In an optional embodiment, the shoulders of the straight block 5 and the cross block 9 are detachably connected by a second fastener 10. Further, the cross block 9 and the straight block 5 are conventionally connected using the second fastener 10, and the thickness difference between the connection between the cross block 9 and the straight block 5 is adjusted to a uniform height by the shoulder provided on the cross block 9, as shown in Figures 12 and 13. In special cases, the connection between the cross block 9 and the straight block 5 can also be made using an angle iron eyelet plate 6, as shown in Figure 7. The second fastener 10 consists of a Phillips head countersunk screw 11, a flat washer, and a spring washer.
[0084] In an optional implementation, the area of each slab 13 does not exceed 0.5 m², and the gap between adjacent slabs 13 is not greater than 3 mm.
[0085] In a second aspect, the present invention provides an installation method based on the ship engine room paving assembly of any of the foregoing embodiments;
[0086] The installation method includes at least the following steps:
[0087] S100, Conduct on-site surveying and drawing of the structural layout diagram of the paving frame device;
[0088] S200. Fabricate each component according to the structural layout drawing;
[0089] S300. Install the manufactured components according to the frame layout drawing to obtain the ship engine room paving assembly.

[0092] S600. Install the paving panel 13 onto the ship's engine room paving panel assembly according to the paving panel layout diagram.
[0093] In step S100, the actual ship survey and the drawing of the 13-frame layout diagram of the paving platform include the following specific contents:
[0094] 1. The overall height of the paving frame device 12 is generally initially determined by the height of the equipment, pipelines, valves and accessories in the "engine room layout drawing"; the height of the paving frame device 12 also needs to consider whether it will affect the opening and closing of the passage door; if a paving 13 passage needs to be erected in a local area, the passage height is generally 50-100mm higher than the equipment surface, such as the shaft tunnel paving frame device 12, which is generally 50-100mm higher than the upper surface of the shaft.
[0095] 2. Based on the actual situation and the requirements of the drawing dimensions, draw a layout diagram of the paving frame device 12, measure the dimensions of the longest and most important frame device 12 in the surrounding area and main passage, and mark the dimensions on the layout diagram.
[0096] 3. Determine the component lengths of the structure according to the main channel structure frame device 12, and each component on the layout drawing of the paving frame device 12 should be clearly marked.
[0097] 4. The distance between the frame device 12 and the equipment: The frame device 12 should maintain a distance of 80-100mm from the main unit, diesel generator, etc., and a distance of 30-50mm from general vibration damping machinery. It should also have a gap of not less than 10mm from general equipment.
[0098] 5. The frame devices 12 around the equipment and around the frame device 12 should have their folded edges facing upwards, while the frame devices 12 in the middle of other frame devices 12 should have their folded edges facing downwards.
[0099] 6. When constructing the slab frame device 12, the size of each slab 13 should generally not exceed 0.5m2.
[0100] 7. If only the plank 13 is installed on the frame device 12, then the frame device 12 is generally made of angle steel.
[0101] 8. The frame device 12 is composed of reinforcing plate 2, support 3, straight bar 5, cross bar 9, and angle steel eye plate connected by welding or fasteners.
[0102] In step S200, the fabrication of each component based on the 13-panel frame layout drawing includes the following specific details:
[0103] According to the layout diagram of the 13-panel structure, the support 3, straight bar 5, and cross bar 9 are cut into pieces. The straight bar 5 is marked, drilled, and countersunk. The cross bar 9, support 3, and angle iron eyelet plate 6 are marked and drilled.
[0104] Prepare the appropriate number of angle iron eyelets.
[0105] In step S300, the installation of each manufactured component according to the layout drawing of the 13-panel frame includes the following specific steps:

[0107] The frame components are connected to the column 8 in parallel using two angle iron eyelets 6. First, one side of the first angle iron eyelet 6 is welded to the straight block 5. Then, the two angle iron eyelets 6 are connected by the first fastener 4. Finally, the other side of the second angle iron eyelet 6 is welded to the column 8 as shown in Figure 6.
[0108] The passageway on the side of the shaft needs to be equipped with removable railings to facilitate routine maintenance of the intermediate bearing and prevent people from falling.
[0109] If it is necessary to cross the shaft to reach an empty cabin, a bridge needs to be built on the shaft.
[0110] In step S400, the dimensions of each 13-layer paving are measured and marked, and a paving layout diagram is drawn, including the following specific details:
[0111] After the entire framework is completed, confirm the detailed data of each slab 13 according to the shape and size of the upper plane of the framework, and mark the number of each slab 13 on the drawing.
[0112] In step S500, each slab 13 is processed according to the drawn slab layout diagram, and marked with the following specific details:
[0113] 1. Cut and process the 13th paving board according to the dimensions marked on the paving board layout drawing.
[0114] 2. After the processing of the board 13 is completed, it should be flat, smooth and free of burrs.
[0115] In step S600, the installation of paving 13 according to the paving layout diagram includes the following specific steps:
[0116] 1. After the frame is painted, holes should be drilled at the diagonal of each panel 13, and the corresponding frame parts should be tapped and fixed with Phillips head countersunk screws 11 to prevent the panel 13 from sliding or shifting. See Figure 14.
[0117] 2. If there are components to be operated under the base plate 13, hand holes must be drilled in the base plate 13. The number, size, and location of the holes shall be determined on-site according to actual needs. See Figure 15.
[0118] Furthermore, the handhole has a handhole cover 14. A fixing plate 16 for support 3 is provided at the bottom of the handhole, and the fixing plate 16 corresponds to the handhole. The handhole cover 14 is fastened to the fixing plate 16 by a cross-head screw 15.
[0119] In summary, the embodiments of the present invention provide a ship engine room paving assembly and installation method, which have the following advantages:
[0120] 1. In this invention, shoulders are provided at both ends of the horizontal bar 9 to ensure that the horizontal bar 9 is at the same height when installed on the vertical bar 5. Only the vertical support 3 and the horizontal support 3 are welded; the other components can be installed by bolting.
[0121] 2. This installation method significantly reduces the amount of welding and grinding work during the installation of the 13-layer plate, and reduces the environmental pollution caused by the installation process.
[0122] 3. Easy to install and disassemble; repeated disassembly and assembly will not cause damage or waste to the structure.
[0123] 4. The angle iron scraps cut off during the installation of the 13-panel frame can be made into angle steel eyelets, which improves the utilization rate of materials.
[0124] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
