Description

Technical Field

[0001] The invention relates to the field of shipbuilding, and in particular to a design method for a ship piping system and an air duct combined bracket. Background Art

[0002] The ship piping system is a pipeline system used to transport various liquids or gases on the ship. It is responsible for handling various media such as fuel, lubricating oil, cooling water, ballast water, sewage and domestic water. It is a functional system serving the entire ship. The ship's air duct is an important part of the ship's ventilation system. It is used to transport fresh air to various cabins on the ship and discharge the dirty air in the cabin to the outside of the ship. The main function of the ship's air duct is to lead the ventilation of the entire ship and the cooling or heating of the cabin. The ship's piping system and air duct are both important parts of the ship's operation and production design, and occupy a lot of man-hours in ship design and on-site installation.

[0003] In the existing ship piping design process, the piping system and duct bracket are designed separately by two personnel from different professions. Not only does the coordination workload for the designers is huge, which consumes a lot of time for drawing production, but the production department also has a large workload of reading drawings and sorting materials. The construction convenience is poor, the production efficiency is low, and there is a high risk of cross-operation at the production site. Summary of the invention

[0004] In view of the defects existing in the prior art, the present application provides a design method for a combined bracket of a ship piping system and an air duct, so as to solve the technical problems in the prior art such as the separate design and production of ship piping systems and air ducts, large workload, low production efficiency, and high risk of cross-operation at the production site.

[0005] In order to achieve the purpose of the above invention, the technical solution provided by the present invention is as follows:

[0006] A method for designing a combined support for a ship piping system and an air duct comprises the following steps:

[0007] S1. Use 3D software to model and build the ship production design;

[0008] S2. Model the air duct and the ship piping system and create the initial direction of the air duct and the ship piping system;

[0009] S3. Find out the part where the air duct and the ship piping system have basically the same initial direction, and use the ship piping system and air duct combined bracket as the fixed support for the part where the air duct and the ship piping system have basically the same initial direction;

[0010] S4. The ship model perfection rate reaches the first value, the first risk point of the model is checked, and the first risk point of the model is modified, and the combined support setting area is determined;

[0011] S5. Select a reasonable combined bracket, establish a model of the combined bracket, and refine the combined model in the ship model;

[0012] S6. When the ship model perfection rate reaches the second value, the second risk point of the model is checked and modified until the model of the combined bracket is ready for drawing;

[0013] S7. Generate and store the design data of the combined bracket, and complete the design of the combined bracket of the ship piping system and the air duct.

[0014] In one embodiment, the first value is 70%, the second value is 98%, the first risk points of the model include: where the duct and ship piping system models are inconsistent with relevant specifications, where the duct and ship piping system models interfere with other professional models, where external professional modifications lead to changes in the direction of the piping system or duct, and where the on-site construction of the piping system or duct is difficult; the second risk points of the model include: where the combined bracket cannot be installed in the same stage, where the combined bracket affects the ship's loading, and where the shipowner adds an account or personalized opinion.

[0015] In one embodiment, the combined bracket selected in step S5 includes a support body fixed on the hull, a duct clamp for fixing the duct, and a pipe clamp for fixing the ship's pipeline, and the duct clamp and the pipe clamp are both fixed on the support body.

[0016] In one embodiment, the support body includes an L-shaped frame, a first horizontal frame, a vertical frame and a second horizontal frame, the ends of the L-shaped frame are fixed on the hull, the first horizontal frame is arranged above the horizontal edge of the L-shaped frame, and one end of the first horizontal frame is fixedly connected to the L-shaped frame, the two vertical frames are arranged in parallel and are both fixed on the lower side of the horizontal edge of the L-shaped frame, the two ends of the second horizontal frame are respectively fixedly connected to the two vertical frames, the pipe clamps of the pipe system are fixedly arranged on the horizontal edges of the first horizontal frame and the L-shaped frame, and the duct clamps are fixedly arranged on the second horizontal frame.

[0017] In one embodiment, the L-shaped frame, the first horizontal frame, the vertical frame and the second horizontal frame are all angle steels, the air duct is a square air duct, the air duct clamp is a C-shaped clamp, and the pipe system clamp is a U-shaped clamp.

[0018] In one embodiment, in step S4, determining the combined support junction area includes ensuring that the paths of the air duct and the pipe system are consistent in direction while maintaining the shortest distance, thereby reasonably expanding the radiation range of the combined support.

[0019] In one embodiment, step S5 further includes checking the strength of the air duct and the ship piping system using simulation software.

[0020] In one embodiment, the design data of the combined bracket includes a production drawing, a parts list drawing and an installation drawing of the combined bracket.

[0021] In one implementation, in step S7, if the installation stages of the ship piping system and the air duct are the same, the ship piping system design department will take the lead in generating and storing the design data of the combined bracket; if the installation stages of the ship piping system and the air duct are inconsistent, the ship piping system design department will take the lead in generating and storing the part of the combined bracket that supports and fixes the ship piping system, and the air duct design department will take the lead in generating and storing the relevant part of the combined bracket that supports and fixes the air duct.

[0022] Compared with the prior art, this application has at least the following beneficial effects:

It improves design efficiency, reduces design hours, and reduces the weight of designer configuration and ship design outfitting. After the present invention outputs relevant data, that is, after the drawings are released, on the one hand, the combined brackets for air ducts and pipe systems become drawings that can be used for construction by on-site departments, and on the other hand, reduces the workload of the production department in reading drawings and sorting materials, increases construction convenience, and avoids waste of production resources and the risk of cross-operation at the production site.

[0035] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0036] like Figure 1 As shown, the present invention discloses a design method for a ship piping system and a wind duct combined bracket, comprising the following steps:

[0037] S1. Use 3D software to model and build the ship production design;

[0038] S2. Model the air duct and the ship piping system and create the initial direction of the air duct and the ship piping system;

[0039] S3. Find out the part where the air duct and the ship piping system have basically the same initial direction, and use the ship piping system and air duct combined bracket as the fixed support for the part where the air duct and the ship piping system have basically the same initial direction;

[0040] S4. The ship model perfection rate reaches the first value, the first risk point of the model is checked, and the first risk point of the model is modified, and the combined support setting area is determined;

[0041] S5. Select a reasonable combination bracket and establish a model of the combination bracket, such as Figure 3 As shown, the combined model is refined in the ship model;

[0042] S6. When the ship model perfection rate reaches the second value, the second risk point of the model is checked and modified until the model of the combined bracket is ready for drawing;

[0043] S7. Generate and store the design data of the combined bracket, and complete the design of the combined bracket of the ship piping system and the air duct.

[0044] In this embodiment, the first value is 70%, the second value is 98%, and the first risk point of the model includes: the place where the duct and ship piping system model is inconsistent with the relevant specifications, the place where the duct and ship piping system model interferes with other professional models, the place where the external professional modification causes the change of the piping system or duct direction, and the place where the piping system or duct is difficult to construct on site. The first risk point of the model includes: the place where the combined bracket cannot be installed in the same stage, the place where the combined bracket affects the ship's loading, the shipowner's additional account or personalized opinions and other uncertain factors.

[0045] The combined bracket selected in step S5 includes a support body 3 fixed on the hull, a duct clamp 1 for fixing the duct 5, and a pipe clamp 2 for fixing the ship pipeline 4. The duct clamp 1 and the pipe clamp 2 are both fixed on the support body 3. Figure 2As shown, in this embodiment, the support body 3 includes an L-shaped frame 301, a first horizontal frame 302, a vertical frame 303 and a second horizontal frame 304. The end of the L-shaped frame 301 is fixed on the hull, the first horizontal frame 302 is arranged above the horizontal edge of the L-shaped frame 301, and one end of the first horizontal frame 302 is fixedly connected to the L-shaped frame 301, the two vertical frames 303 are arranged in parallel and are both fixed on the lower side of the horizontal edge of the L-shaped frame 301, and the two ends of the second horizontal frame 304 are respectively fixedly connected to the two vertical frames 303, the pipe system pipe clamp 2 is fixedly arranged on the horizontal edges of the first horizontal frame 302 and the L-shaped frame 301, and the air duct clamp 1 is fixedly arranged on the second horizontal frame 304. Among them, the L-shaped frame 301, the first horizontal frame 302, the vertical frame 303 and the second horizontal frame 304 are all angle steels. In this embodiment, the air duct 5 is a square air duct, the air duct clamp 1 is a C-shaped clamp, and the pipe system pipe clamp 2 is a U-shaped pipe clamp.

[0046] In step S4, determining the combined support junction area includes ensuring that the paths of the air duct and the pipe system are in the shortest distance so that the paths of the air duct and the pipe system are consistent and reasonably expanding the radiation range of the combined support.

[0047] Step S5 also includes using simulation software to check the strength of the air duct and the ship piping system to ensure that the selection and setting position of the combined bracket can provide sufficient support for the air duct and the ship.

[0048] like Figure 4-6 As shown, the design data of the combined bracket includes a manufacturing drawing, a parts list drawing and an installation drawing of the combined bracket for the reading of the manufacturer and the installation department of the combined bracket. In step S7, if the installation stages of the ship piping system and the air duct are the same, the ship piping system design department will take the lead in generating and storing the design data of the combined bracket; if the installation stages of the ship piping system and the air duct are not the same, the ship piping system design department will take the lead in generating and storing the part of the combined bracket that supports and fixes the ship piping system, and the air duct design department will take the lead in generating and storing the relevant part of the combined bracket that supports and fixes the air duct, so as to facilitate the subsequent installation of the ship piping system and the air duct.

[0049] When the ship piping and air duct combined bracket design method of the present application is not adopted, different brackets are used to support the ship piping and air duct respectively. The weight of one ship piping bracket is 50.25 kg, and the weight of one air duct bracket is 61.05 kg. After the ship piping and air duct combined bracket design method of the present application is adopted, the weight of one ship piping and air duct combined bracket is only 81.99 kg, that is, the weight of the ship piping and air duct combined bracket is much less than the sum of the weights of the individual ship piping brackets and the air duct brackets. Therefore, the ship piping and air duct combined bracket design method in the present application reduces the weight of the ship design outfitting.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
