Description

Technical Field

[0001] The invention relates to the technical field of segmented construction, and in particular to a method for using a sand table to observe segmented lightering and loading in a shipyard. Background Art

[0002] In modern shipbuilding, the overall structure of a ship is mainly formed by small sections, which go through a series of processes such as structural integrity, outfitting assembly, and painting, and then through general assembly and loading. A ship can have as few as a dozen or even hundreds of small sections. When multiple ships are being built at the same time in a factory, the sections are even more complicated. Therefore, process control, stacking within the factory, and barging within the factory are very complicated projects.

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

[0004] There are many disadvantages in recording the status and location of each segment in the traditional way of notes, such as the inability to quickly and conveniently share information with others, which is inefficient. Due to the complex construction environment in the factory, the traditional way may also cause segment blockage, resulting in repeated transportation and waste of production resources. In addition, there is a lack of visual actual reference, which leads to a lack of intuitive reference for dispatchers in the management process.

[0005] Although it is more intuitive to record the status of each segment on the segmented network diagram, there may be problems such as multiple erasures 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 comprehensively view the segmented transfer and loading in a shipyard, so as to solve the problems existing in the above-mentioned background technology.

[0007] A method for using a sand table to observe the segmented transfer and loading in a shipyard area, specifically comprising the following steps:

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

[0009] S2, construct the sections in the section manufacturing workshop in the shipyard, and according to the product to which the current section belongs, simultaneously make the 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 a plurality of color-filled areas for reflecting the completion status of the segmented pre-installation operation, and one color-filled area corresponds to one segmented pre-installation process;

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

[0012] After the current segment completes all the processes before loading, the current segment is assembled with other segments to form a total segment, and the segment models to be assembled are stacked in the dock area of ​​the sandbox model;

[0013] When the current section is moved from the current construction area to the next construction area, the section transfer route is planned according to the section distribution displayed on the sand table model.

[0014] Preferably, segmented manufacturing areas, segmented stacking areas, segmented painting areas, dock areas, and transportation roads are arranged in the sand table model, and the actual sizes of the segmented manufacturing areas, segmented stacking areas, segmented painting areas, dock areas, and transportation roads are marked.

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

[0016] The specific steps of moving the current segment to each segment pre-installation construction area in sequence according to the construction order and simultaneously transporting its segment model from the previous construction area on the sandbox 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 coloring area of ​​the segment model that reflects the completion status of the sandblasting operation is painted with the same color as the segment model;

[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 sandbox model to the segment painting area. After the segment painting is completed, the coloring area of ​​the segment model used to reflect the completion status of the painting operation is painted with the same color as the segment model;

[0019] Finally, the current section is transported from the section painting area to the section stacking area for outfitting and pipe pre-installation operations, and its section model is simultaneously moved from the section painting area of ​​the sand table model to the section stacking area. After the section outfitting is completed, the coloring area of ​​the section model used to reflect the completion status of the outfitting operation is painted with the same color as the section model; after the pipe pre-installation is completed, the coloring area of ​​the section model used to reflect the completion status of the pipe pre-installation operation is painted with the same color as the section model.

[0020] Preferably, when the segments need to be transported to the segment stacking area, a suitable segment stacking area is selected according to the segment stacking conditions of each segment stacking area on the sandbox model.

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

[0022] Preferably, the segmented model is a cube block made in proportion to 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 sandbox model and the factory area.

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

[0024] Preferably, a plurality of products are constructed simultaneously in the shipyard, and the segment models of the segments belonging to the same product have the same color, and one product corresponds to only one color.

[0025] The beneficial effects of the present invention are:

[0026] 1. The present invention makes a sand table model that is exactly the same as the internal layout of the shipyard, and makes a segmented model in the same proportion. The segmented model is placed on the sand table model according to the manufacturing stage of the segment, and the segmented model of each construction area in the sand table model is dynamically adjusted and moved according to the construction of the segment. This effectively solves the problem of insufficient intuitive information on segment stacking and barging in the existing status update of segment stacking, segment barging, and segment loading in the shipyard, while also improving the efficiency of segment barging and enhancing the intuitiveness of segment status information.

[0027] 2. The present invention can conveniently and intuitively understand the stacking position and status information of each section, so that management personnel can better coordinate the manufacturing, outfitting, transshipment, assembly, and loading of the sections, while strengthening the collaboration between product management personnel and reducing the waste of transshipment resources.

[0028] 3. The present invention visualizes the information that originally existed in paper or electronic version, making the production process information and production scheduling more intuitive and clear. And it uses proportional reduction and magnetic material manufacturing to make the size information clearer, which is convenient for production scheduling, and the sand table model can be hung on the wall to reduce the space occupied.

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

[0032] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is described below by the specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

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

[0034] 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.

[0035] The present invention provides a method for using a sand table to observe the segmented lightering and loading in a shipyard, which specifically includes the following steps:

[0036] S1, produce a sand table model that is exactly the same as the internal layout of the shipyard according to a specific proportion.

[0037] Usually, the area where the shipyard is located is equipped with a section manufacturing area, a section stacking area, a section painting area, a section loading area, a dock area, and a transportation road. The dock area is generally located at the seaside or the riverside, the section loading area is located next to the dock area, and there may be a transportation road between the section loading area and the dock area, the section manufacturing area is located next to the section loading area, and there are transportation roads and office buildings between the section loading area and the section manufacturing area, and the section stacking area and the section painting area are located in the open area next to the section manufacturing area. It should be noted that some wide transportation roads can also be used as temporary stacking areas. Therefore, there may be multiple section stacking areas in the shipyard. When actually stacking the sections, it is necessary to select a suitable stacking area with a short transportation distance to stack the sections according to the space utilization of each section stacking area.

[0038] Therefore, the produced sand table model is exactly the same as the internal layout of the shipyard. The sand table model also has segmented manufacturing areas, segmented stacking areas, segmented painting areas, dock areas, and transportation roads. The sand table sizes of the segmented manufacturing areas, segmented stacking areas, segmented painting areas, dock areas, and transportation roads are all proportionally reduced according to their actual sizes.

[0039] The actual dimensions of the segment manufacturing area, segment stacking area, segment painting area, dock area and transportation road are marked on the sand table model.

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

[0041] S2, build the sections in the section manufacturing workshop within the shipyard, and according to the product to which the current section belongs, simultaneously make the section model of the color of the product in the same proportion, and fix the section model in the section manufacturing area of ​​the sandbox model.

[0042] Usually, multiple products are constructed simultaneously in a shipyard, where the products refer to ships. For example, if ship 1 and ship 2 are constructed simultaneously, there are a total of 2 products constructed simultaneously in the shipyard.

[0043] The segment models of the segments belonging to the same product have the same color, and one product corresponds to only one color, that is, the segment models of the segments of different products are distinguished by different colors.

[0044] In this embodiment, the segmented model is a cube block made in proportion to 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 sandbox model and the factory area.

[0045] The surface of the segmented model is provided with a plurality of coloring areas for reflecting the completion status of the segmented pre-installation operation, and one coloring area corresponds to one segmented pre-installation process. The segmented pre-installation operation includes segmented sandblasting, painting, outfitting and pipe pre-installation. The segmented sandblasting, outfitting and pipe pre-installation are all carried out in the segmented stacking area, and the segmented painting is carried out in the segmented painting area. When a segmented pre-installation process is completed, the corresponding coloring area on the surface of the segmented model must be immediately painted with the same color as the segmented model (when not painted, the coloring area is white). In this embodiment, the upper surface of the segmented model is divided into four coloring areas of equal area and size, and the four coloring areas correspond to the four segmented pre-installation processes of sandblasting, painting, outfitting and pipe pre-installation.

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

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

[0048] Specifically, the specific steps of moving the current segment to each segment pre-installation construction area 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 coloring area of ​​the segment model that reflects the completion status of the sandblasting operation is painted with the same color as the segment model;

[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 sandbox model to the segment painting area. After the segment painting is completed, the coloring area of ​​the segment model used to reflect the completion status of the painting operation is painted with the same color as the segment model;

[0051] Finally, the current section is transported from the section painting area to the section stacking area for outfitting and pipe pre-installation operations, and its section model is simultaneously moved from the section painting area of ​​the sand table model to the section stacking area. After the section outfitting is completed, the coloring area of ​​the section model used to reflect the completion status of the outfitting operation is painted with the same color as the section model; after the pipe pre-installation is completed, the coloring area of ​​the section model used to reflect the completion status of the pipe pre-installation operation is painted with the same color as the section model.

[0052] After the current segment completes all the processes before loading, the current segment will be assembled with other segments to form a total segment. At the same time, the segment models to be assembled will be stacked in the dock area of ​​the sandbox model.

[0053] During the above-mentioned segmented construction process, when a segment is moved from the current construction area to the next construction area, the segmented transfer route can be directly planned according to the segmented distribution displayed on the sand table model to ensure that there will be no other segments blocking its transportation during the segmented transportation route.

[0054] Preferably, during the above-mentioned segmented construction process, when the segments need to be transported to the segmented stacking area, a suitable segmented stacking area is selected for segmented stacking according to the segmented stacking conditions 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 preinstallation operations can be the same segmented stacking area or different segmented stacking areas.

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

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

[0057] It should be clear that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
