This effectively solves the problem of insufficient intuitiveness in updating the status of segmented stacking and barge transport within existing shipyard systems, while also improving segmented barge transport efficiency and enhancing the intuitiveness of segmented status information.

Description

Technical Field

[0001] This invention relates to the field of segmented construction technology, and in particular to a method for using a sand table to view the segmented barge transport and loading within a shipyard area. Background Technology

[0002] In modern shipbuilding, the overall structure of a ship is mainly composed of small sections that undergo a series of processes, including structural integrity, outfitting assembly, and painting, before being assembled and mounted. A single ship may have as few as a dozen or even hundreds of sections. When multiple ships are under construction simultaneously in a shipyard, the number of sections becomes even more complex. Therefore, controlling the process of section construction, stacking within the shipyard, and transporting them within the shipyard is a very complex engineering project.

[0003] In actual shipbuilding work, we mainly rely on pens to record the location of each section, the status of completed processes, etc., and then record the status of each section on the section assembly network diagram to grasp and control the overall assembly and assembly status of the entire ship.

[0004] Recording the status and location of each segment using traditional note-taking methods has many drawbacks, such as the inability to quickly and easily share information with others, resulting in low efficiency. Due to the complex construction environment within the factory area, the traditional method may also cause segment congestion, leading to duplicate transportation and wasting production resources. Furthermore, the lack of visual, physical references means that dispatchers lack intuitive reference points during the management process.

[0005] While recording the status of each segment on a segmented network diagram is relatively intuitive, it may suffer from issues such as multiple alterations and untimely updates of status information. Summary of the Invention

[0006] In view of this, the present invention provides a method for using a sand table to view the segmented barge transport and loading within a shipyard area, in order to solve the problems existing in the background art.

[0007] A method for using a sand table to visualize the segmented barge transport and loading processes within a shipyard area specifically includes the following steps:

[0008] S1, a sand table model that is exactly the same as the internal layout of the shipyard is made according to a specific scale;

[0009] S2, build sections in the section manufacturing workshop in the shipyard area, and according to the product to which the current section belongs, make a section model of the color of the product in the same proportion, and fix the section model in the section manufacturing area of ​​the sand table model.

[0010] The surface of the segmented model is provided with multiple coloring areas to reflect the completion status of the segmented pre-assembly operation, and each coloring area corresponds to a segmented pre-assembly process.

[0011] S3, after the current segment is completed, the current segment is transported to the pre-assembly construction area of ​​each segment in the construction sequence, and its segment model is moved from the previous construction area on the sand table model to the corresponding construction area. According to the construction completion status, the corresponding color area of ​​the segment model is painted with the same color as the segment model.

[0012] After the current segment completes all the procedures before being assembled, the current segment is assembled with other segments to form a whole segment. At the same time, the model of the assembled segment is stacked in the dock area of ​​the sand table model.

[0013] When the current segment moves from the current construction area to the next construction area, the segment transportation route is planned according to the segment distribution shown in the sand table model.

[0014] Preferably, the sand table model includes a segmented manufacturing area, a segmented stacking area, a segmented painting area, a dock area, and a transportation road, and the actual dimensions of the segmented manufacturing area, segmented stacking area, segmented painting area, dock area, and transportation road are marked.

[0015] Preferably, the segmented pre-assembly operation in step S3 includes segmented sandblasting, painting, outfitting, and pipe pre-assembly, wherein segmented sandblasting, outfitting, and pipe pre-assembly are all carried out in the segmented stacking area, and segmented painting is carried out in the segmented painting area;

[0016] The specific steps for moving the current segment to the pre-assembly construction area of ​​each segment in sequence according to the construction order, and simultaneously transporting its segment model from the previous construction area on the sand table model to the corresponding construction area are as follows:

[0017] First, the current segment is transported from the segment construction workshop to the segment stacking area for sandblasting, and its segment model is simultaneously moved from the segment manufacturing area of ​​the sand table model to the segment stacking area. After the segment sandblasting is completed, the same color as the segment model is painted in the coloring area of ​​the segment model that reflects the completion status of the sandblasting operation.

[0018] Then, the current segment is transported from the segment stacking area to the segment painting area for painting, and its segment model is simultaneously moved from the segment stacking area of ​​the sand table model to the segment painting area. After the segment painting is completed, the same color as the segment model is painted in the color-filling area of ​​the segment model that reflects the completion status of the painting operation.

[0019] Finally, the current segment is transported from the segment painting area to the segment stacking area for outfitting and pipe pre-assembly. Simultaneously, its segment model is moved from the segment painting area of ​​the sand table model to the segment stacking area. After the segment outfitting is completed, the color-filling area of ​​the segment model, which reflects the completed outfitting operation, is painted with the same color as the segment model. After the pipe pre-assembly is completed, the color-filling area of ​​the segment model, which reflects the completed pipe pre-assembly operation, is painted with the same color as the segment model.

[0020] Preferably, when segments need to be transported to the segment stacking area, a suitable segment stacking area is selected based on the segment stacking situation of each segment stacking area on the sand table model.

[0021] Preferably, the sand table model is set on the wall of the shipyard area, and the sand table model is made of magnetic material, with segmented models adsorbed and fixed on the sand table model.

[0022] Preferably, the segmented model is a cube made proportionally based on the longest side of the length, width, and height of the actual segment, and the size ratio between the segmented model and its corresponding actual segment is equal to the size ratio between the sand table model and the factory area.

[0023] Preferably, the segmented model is marked with its actual dimensions.

[0024] Preferably, multiple products are being constructed simultaneously within the shipyard area, and the segment models of segments belonging to the same product have the same color, with each product corresponding to a unique color.

[0025] The beneficial effects of this invention are:

[0026] 1. This invention creates a sand table model that is identical to the internal layout of a shipyard, and produces segmented models at the same scale. Based on the manufacturing stage of each segment, the segmented models are placed on the sand table model. The segmented models in each construction area of ​​the sand table model are dynamically adjusted and moved according to the construction of each segment. This effectively solves the problem that the segment stacking and transportation information in existing shipyards is not intuitive enough. At the same time, it improves the efficiency of segment transportation and enhances the intuitiveness of segment status information.

[0027] 2. This invention allows for a convenient and intuitive understanding of the stacking location and status information of each segment, facilitating better coordination among managers in the manufacturing, outfitting, transportation, assembly, and mounting of segments. It also strengthens collaboration among product managers and reduces waste of transportation resources.

[0028] 3. This invention visualizes information that previously existed in paper or electronic form, making production process information and scheduling more intuitive and clear. Furthermore, the use of proportionally scaled-down, magnetic materials ensures clearer dimensional information, facilitating production scheduling, and allows the sand table model to be hung on a wall, reducing its space occupation.

[0029] 4. By scaling down the sand table model and segmented models to the actual size of their corresponding real objects, the space utilization of each construction area in the entire factory area can be clearly and intuitively viewed in the sand table model. It is also possible to directly observe and understand the segmented stacking situation of a certain stacking site to determine whether there is enough space to stack new segments.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0033] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0034] To better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.

[0035] This invention provides a method for observing the segmented barge transport and loading within a shipyard using a sand table, specifically including the following steps:

[0036] S1, a sand table model is made according to a specific scale, which is exactly the same as the internal layout of the shipyard.

[0037] Typically, a shipyard area includes sections manufacturing, stacking, painting, loading, docking, and transport roads. The docking area is usually located by the sea or river. The loading area is located next to the docking area, possibly separated from it by a transport road. The manufacturing area is located next to the loading area, separated from it by transport roads and office buildings. The open area next to the manufacturing area contains the stacking and painting areas. It should be noted that some wide transport roads can also be used as temporary stacking areas. Therefore, there may be multiple stacking areas within a shipyard. When stacking sections, the appropriate stacking area with the shortest transport distance should be selected based on the space utilization of each stacking area.

[0038] Therefore, the sand table model produced is exactly the same as the internal layout of the shipyard. The sand table model also includes sections manufacturing area, sections stacking area, sections painting area, dock area, and transportation roads. The sand table size of the sections manufacturing area, sections stacking area, sections painting area, dock area, and transportation roads is scaled down proportionally according to their actual size.

[0039] The sand table model is marked with the actual dimensions of the segment manufacturing area, segment stacking area, segment painting area, dock area, and transportation roads.

[0040] In this embodiment, the sand table model is made of magnetic material to facilitate the fixation of the segmented models. The sand table model can fully display a series of locations involved in the segmented construction, transportation, stacking, loading, and docking within the shipyard area.

[0041] S2. Construct sections in the section manufacturing workshop within the shipyard area, and simultaneously produce section models of the same color as the product to which the current section belongs, in the same proportion, and fix the section models in the section manufacturing area of ​​the sand table model.

[0042] Typically, multiple products are under construction simultaneously within a shipyard area. These products refer to ships. For example, if ship 1 and ship 2 are under construction simultaneously, then there are a total of 2 products under construction simultaneously within the shipyard area.

[0043] The segmentation models of segments belonging to the same product have the same color, and each product corresponds to a unique color. That is, the segmentation models of segments of different products are distinguished by different colors.

[0044] In this embodiment, the segmented model is a cube made proportionally based on the longest side of the length, width, and height of the actual segment. The size ratio between the segmented model and its corresponding actual segment is equal to the size ratio between the sand table model and the factory area.

[0045] The surface of the segmented model is provided with multiple color-filled areas to reflect the completion status of the segmented pre-assembly work. Each color-filled area corresponds to one segmented pre-assembly process. The segmented pre-assembly work includes segmented sandblasting, painting, outfitting, and pipe pre-assembly. Segmented sandblasting, outfitting, and pipe pre-assembly are all carried out in the segmented stacking area, while segmented painting is carried out in the segmented painting area. Upon completion of a segmented pre-assembly process, the corresponding color-filled area on the surface of the segmented model must be immediately painted with the same color as the segmented model (when unpainted, the color-filled area is white). In this embodiment, the upper surface of the segmented model is divided into four color-filled areas of equal size, each corresponding to one of the four segmented pre-assembly processes: sandblasting, painting, outfitting, and pipe pre-assembly.

[0046] Preferably, the segmented model is marked with its actual dimensions.

[0047] S3, after the current segment is completed, the current segment is transported to the pre-assembly construction area of ​​each segment in the construction sequence, and its segment model is moved from the previous construction area on the sand table model to the corresponding construction area. According to the construction completion status, the corresponding color area of ​​the segment model is painted with the same color as the segment model.

[0048] Specifically, the steps for moving the current segment to the pre-assembly construction area of ​​each segment in sequence according to the construction order, and simultaneously transporting its segment model from the previous construction area on the sand table model to the corresponding construction area are as follows:

[0049] First, the current segment is transported from the segment construction workshop to the segment stacking area for sandblasting, and its segment model is simultaneously moved from the segment manufacturing area of ​​the sand table model to the segment stacking area. After the segment sandblasting is completed, the same color as the segment model is painted in the coloring area of ​​the segment model that reflects the completion status of the sandblasting operation.

[0050] Then, the current segment is transported from the segment stacking area to the segment painting area for painting, and its segment model is simultaneously moved from the segment stacking area of ​​the sand table model to the segment painting area. After the segment painting is completed, the same color as the segment model is painted in the color-filling area of ​​the segment model that reflects the completion status of the painting operation.

[0051] Finally, the current segment is transported from the segment painting area to the segment stacking area for outfitting and pipe pre-assembly. Simultaneously, its segment model is moved from the segment painting area of ​​the sand table model to the segment stacking area. After the segment outfitting is completed, the color-filling area of ​​the segment model, which reflects the completed outfitting operation, is painted with the same color as the segment model. After the pipe pre-assembly is completed, the color-filling area of ​​the segment model, which reflects the completed pipe pre-assembly operation, is painted with the same color as the segment model.

[0052] After the current segment completes all the procedures before being assembled, it will be assembled with other segments to form a complete segment. At the same time, the model of the assembled segment will be stacked in the dock area of ​​the sand table model.

[0053] During the aforementioned segmented construction process, when a segment is moved from the current construction area to the next construction area, the segment transportation route can be directly planned based on the segment distribution shown in the sand table model, to ensure that no other segments will obstruct the transportation of the segment during the transportation route.

[0054] Preferably, during the above-mentioned segmented construction process, when segments need to be transported to the segmented stacking area, a suitable segmented stacking area is selected for segmented stacking based on the segmented stacking situation of each segmented stacking area on the sand table model. Therefore, for the same segment, the segmented stacking area used for sandblasting operations and the segmented stacking area used for outfitting and pipe pre-installation operations can be the same segmented stacking area or different segmented stacking areas.

[0055] By scaling down the sand table model and segmented models to the actual size of their corresponding real objects, the space utilization of each construction area in the entire factory area can be clearly and intuitively viewed in the sand table model. It is also possible to directly observe and understand the segmented stacking situation of a certain storage site to determine whether there is enough space to stack new segments.

[0056] Preferably, during actual construction, the sand table model can be hung or fixed on the wall of the shipyard area, and the segmented models can be adsorbed and fixed onto the sand table model.

[0057] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
