[0019] Step S102, based on the target three-dimensional model, obtain the outer arc length, side length and sector angle of the sector annular side wall of the target conical silo equipment after unfolding.

[0020] Optionally, step S102 may include: Extract the lower base radius, first side length and second side length of the truncated cone in the target three-dimensional model.

[0021] Among them, the radius of the lower base of the truncated cone is half of the longer base of the isosceles trapezoid corresponding to the main view of the target three-dimensional model, the length of the first side is the distance from the intersection of the two extended lines of the isosceles trapezoid to any end point of the longer base of the isosceles trapezoid, and the length of the second side is the distance from the intersection of the two extended lines of the isosceles trapezoid to any end point of the shorter base of the isosceles trapezoid.

[0022] According to the radius of the bottom surface of the truncated cone, the outer arc length of the fan-shaped annular side wall of the target conical silo equipment after unfolding is obtained.

[0023] The difference between the first side length and the second side length is calculated to obtain the side length of the fan-shaped annular side wall of the target conical silo equipment after it is unfolded.

[0024] According to the outer arc length and the first side length, the fan-shaped angle of the fan-shaped annular side wall of the target conical silo equipment after unfolding is obtained.

[0025] Combination Figure 4 As shown, in this embodiment, basic geometric parameters can be extracted by selecting a model, such as Figure 5 and Figure 6 As shown, the extracted geometric parameters may include the radius of the cone top circle (That is, the radius of the bottom surface of the truncated cone. Since the steel plate used in the target 3D model has a certain thickness, the radius of the bottom surface of the truncated cone can be calculated according to the middle position of the thickness of the steel plate when extracting the radius of the bottom surface of the truncated cone), the total length of the side from the intersection of the cone bottom to the top (also known as the first side length), the side length from the intersection of the cone base to the cone base (that is, the length of the second side), the cone is fan-shaped after expansion, and the total length of the fan-shaped side (that is, the side length of the fan-shaped annular side wall of the target conical silo equipment after expansion) can be simply calculated as , the outer arc length of the fan after the top is unfolded (that is, the outer arc length of the fan annular side wall of the target conical silo equipment after unfolding) is , the fan angle is .

[0026] Step S103, according to the outer arc length, side length, fan angle, steel plate width and single block optimal arc length reference value, obtain the side length of each side wall section, the remaining side wall side length and the outer arc length of each side wall section after the steel layout division of the fan annular side wall, and record them as layout data.

[0027] Among them, the steel plate width is the width of the steel plate used when the fan-shaped side wall is used for steel layout and division.

[0028] Optionally, step S103 may include: The outer arc length is used as the outer arc length of the current section of the side wall when dividing the steel layout of the fan annular side wall. According to the outer arc length of the current section of the side wall and the reference value of the optimal arc length of a single block, the number of blocks of the current section of the side wall when dividing the steel layout of the fan annular side wall is obtained.

[0029] The side length of the side wall of the current section is obtained according to the length of the first side, the fan angle, the number of blocks of the side wall of the current section and the width of the steel plate.

[0030] According to the side length and the side length of the current segment side wall, the side length of the remaining side walls in the fan-shaped side wall except the current segment side wall is obtained.

[0031] According to the side length of the current side wall and the side length of the remaining side walls, the outer arc of the remaining side walls in the fan-shaped side wall except the current side wall is drawn, and the outer arc length of the next side wall is obtained according to the outer arc.

[0032] Take the outer arc length of the next side wall section as the new arc length of the current side wall section, repeat the steps of "obtaining the number of blocks of the current side wall section when dividing the steel layout of the fan-shaped side wall according to the outer arc length of the current side wall section and the reference value of the optimal arc length of a single block" and subsequent steps until the remaining side wall side length is 0, and the layout data is obtained.

[0033] Optionally, the side length of the side wall of the current section is obtained according to the first side length, the fan angle, the number of side wall blocks of the current section and the width of the steel plate, including: according to , obtain the side length of the side wall of the current segment; in, For the The length of the side wall of the segment, The fan annular side wall is divided into The side length of the fan corresponding to the remaining side wall after the segment side wall, is the length of the first side, is the width of the steel plate, is the fan angle, For the The number of blocks of the segment side wall.

[0034] Optionally, according to the side length and the side length of the current segment side wall, obtaining the side length of the remaining side walls in the fan-shaped side wall except the current segment side wall includes: according to , obtain the side length of the remaining side walls in the fan annular side wall except the side wall of the current segment; in, The fan ring side wall except the The remaining side wall length outside the segment side wall, is the side length, For the The side length of the side wall of the segment.

[0035] like Figure 7 Then enter the data input interface and start inputting layout data. The interface shows the optimal arc length reference value of each block after segmentation (for example, it can be obtained from feedback from workers with construction experience). According to the optimal arc length reference value of each block and the actual construction situation, it can be comprehensively judged how many blocks a certain section should be divided into (for example, if the construction is tight, one less block can be divided to reduce the cutting seam). The arc length of the first section has been displayed in the input interface. (i.e. the outer arc length of the fan-shaped annular side wall of the target conical silo equipment after it is unfolded). The first segment is divided into blocks according to this value. The next interface (i.e. Figure 8 ) will display the arc length of the next segment (that is, the outer arc length of the next side wall), press Calculation, each time the script is run, only a certain section of the block can be divided (because only the outer arc length of the next section can be calculated at a time), and multiple runs can complete all the segmentation and blocking. The steel plate width can be input according to the actual on-site purchase.

[0036] For example, after entering the block data of a certain section, the side length of the side wall of the section will be calculated. ,for: and through , , The remaining side wall length can be easily calculated Then you can directly enter commands in Dynamo to draw geometric shapes using the calculated parameters. , , Draw the fan after expansion, by evenly dividing the number of blocks Draw the small fan-shaped blocks, through , Draw the outer arc of the next side wall. Finally, the outer arc length of the next side wall can be directly measured through the command. . Thus, the various data required for typesetting can be automatically calculated through scripts, and the typesetting plan can be determined manually, which reduces the difficulty of typesetting, reduces typesetting time, and increases work efficiency.

[0037] like Figure 8 As shown, you can finally enter the data display interface, which can only be used for data display. When the layout plan is completed, you can click Save on this interface and set the path to save the layout plan data to provide layout data for subsequent steps. Figure 8 The steel plate width W, the number of evenly divided blocks n (i.e. Number of side wall blocks ) can be directly introduced from the previous interface data. The fan arc length l is the data calculated from the previous interface. It can be placed at the bottom of this column, such as automatically calculating the length of the fourth arc segment when the third segment is reached. , The value is placed in the fourth row of the sector arc length l column. Since there is no other data in this row, the other cells are blank. The remaining sector side length Sn is the data calculated in the previous interface. , it is placed here to estimate how many segments will be divided in the future. When the remaining sector side length Sn is 0, it means there is nothing left, and the current one is the last segment. Figure 8 The remaining length of the n segments in the Segment side wall length .

[0038] Step S104, outputting the side wall layout diagram of the target conical silo equipment according to the layout data, the side wall layout diagram including the main view of the target conical silo equipment, the fan-shaped side wall expansion diagram, the fan-shaped side wall layout division diagram, the sub-diagram after the fan-shaped side wall layout division and the layout description, the layout description including the steel utilization rate corresponding to each section of the side wall after the fan-shaped side wall is divided into steel materials by layout.

[0039] Optionally, the process of generating the steel utilization rate may include: according to , calculate the first Steel utilization rate corresponding to the side wall of the segment.

[0040] in, The first step after the steel material layout division of the fan annular side wall Steel utilization rate corresponding to the side wall of the segment, The first The total area of ​​the side walls of the segment, is the width of the steel plate, For the The required length of steel plate for the side wall of the segment, For the Number of segment sidewall blocks, The fan annular side wall is divided into The side length of the fan corresponding to the remaining side wall after the segment side wall, It is the fan-shaped angle.

[0041] like Fig. 9As shown, after running step S104, a data input interface may appear, which has the following features: selecting the silo model for which drawings need to be generated, selecting the path of the conical silo layout data file, and selecting the view for placing the scheme description text. The "selection of the view for placing the scheme description text" is due to software limitations. The scheme description text needs to be placed in a Revit software plane view, which can be ignored here. "Selecting the path of the conical silo layout data file" is to input the storage path of the layout data table generated in step S103 into Dynamo, obtain the file through the command, and then obtain the relevant data in the data table. Exemplarily, the number of segments can be obtained. , Steel plate width , Number of blocks , side wall outer arc length , remaining side wall length , n-th segment side wall side length The function of "Select the silo model for which drawings need to be generated" is similar to the previous step. It can be used to extract the geometric parameters of the model, such as the radius of the cone top circle. , cone bottom circle radius , Total length of the sides from the cone base intersection to the top , the length of the side from the intersection of the cone base to the cone base , the height H from the bottom plane of the cone to the top plane. After the cone is unfolded, it becomes a fan shape, and the total length of the side of the fan ring side wall can be simply calculated from this , the outer arc length of the fan ring side wall after expansion , the inner arc length of the fan ring side wall , fan angle .

[0042] Then the script continues to run and draws the expanded plane geometry through parameters (you can directly enter the command to get the graphics). First, according to , , H draw the conical silo dimension diagram (i.e. the main view of the target 3D model), and then , , Draw the fan annular side wall expansion diagram (that is, the fan annular side wall expansion diagram), and then according to , n-segment side wall side length , Number of blocks , Draw the fan ring side wall layout division diagram (that is, the fan ring side wall layout division diagram), and then according to , , , Draw out the small sectors of each specification after segmentation and block division (that is, the sub-graph after the layout and division of the fan-shaped annular side wall). At this point, the drawing work is completed, and the staff can manually add some drawing annotation work. It should be noted that the script does not draw the blanking diagram, which can be obtained by copying and rotating the sub-graph after the layout and division of the fan-shaped annular side wall. Finally, the script will also generate a text description of the layout plan (that is, the layout description), which may include how many sections, how many blocks each section is divided into, the length and width of the steel plate required for blanking each section, the plate utilization rate during blanking (because the blanking steel plate is rectangular and the finished product is fan-shaped, there will be waste at the corners of the steel plate, which is usually difficult to use, that is, the calculated steel utilization rate), and the length of the cutting seam.

[0043] In this embodiment, the material utilization rate can be directly obtained through the plate utilization rate. When the utilization rate is too low, the layout plan can be optimized to improve the plate utilization rate and create higher economic benefits. In addition, since the blanking process is mainly to cut fan-shaped finished products on rectangular steel plates, calculating the length of the cutting seam can help construction personnel understand the workload of blanking and estimate the working time. It can also be combined with the steel plate utilization rate to optimize the layout plan (improving the utilization rate will increase the number of blocks, and the increase in the number of blocks will lead to a longer cutting seam and increase the blanking time).

[0044] Among them, the number of segments and blocks, the length of the steel plate, and the width of the steel plate can be directly obtained from the existing parameters (among which, the length of the steel plate can be obtained in the process of calculating the steel material utilization rate), and will not be described here. The main calculation process of the steel plate utilization rate is to divide the area of ​​the fan ring side wall by the area of ​​the blank steel plate. The area of ​​the fan ring side wall can be obtained by directly measuring the area of ​​the small fan-shaped geometric figure after the previous step of block division through the command. The width of the steel plate is known, and the main calculation here is the length of the steel plate. Fig.10 As shown in the figure, since the small sectors are arranged on the steel plate in an alternating manner, the calculation of the length of the steel plate is more complicated. Here, it is assumed that the length of the steel plate just meets the fan arrangement (that is, the edge of the steel plate is close to the fan), then: ; in, Fig.10 L in the figure corresponds to the length of the steel plate. , Fig.10 b in corresponds to , Fig.10 The a in , Fig.10 The c in , Fig.10 The x in , Fig.10 The m in corresponds to Through this process, the length of the steel plate can be obtained Finally, the steel utilization rate is obtained, which is the total area of ​​each side wall after segmentation divided by the steel plate area.

[0045] Finally, the cutting seam length will be calculated. Most of the parameters in the cutting seam length can be directly obtained from the previous process, such as the outer arc length of the side wall after segmentation and block division is , the side length of a certain side wall They are all existing, but there will be fan-shaped co-edges in the typesetting process (such as Fig.10 The side edge between the two sectors) will be longer than the side edge when they share the same side. Cut out a small distance, let this small distance be ,but: .

[0046] This completes all the calculation process.

[0047] Optional, such as Fig.11 As shown, after outputting the side wall layout diagram of the target conical silo equipment according to the layout data, it also includes, and can also include: A layout 3D model of the target conical silo equipment is generated according to the layout data and the target 3D model.

[0048] like Fig.12 As shown, this embodiment also automatically generates a typeset conical silo side wall model based on the previous model and the Excel typeset data table. The silo side wall of a certain section can be rotated by adjusting the family parameters and the steel plates can be staggered to facilitate workers' viewing and construction.

[0049] In the embodiment of the present invention, the geometric dimension parameters in the equipment drawing are obtained based on the equipment drawing of the target conical silo equipment, and the target three-dimensional model corresponding to the target conical silo equipment is generated according to the geometric dimension parameters; then, based on the target three-dimensional model, the outer arc length, side length and fan angle of the fan-shaped annular side wall of the target conical silo equipment after expansion are obtained, and the size and plane diagram of the side wall of the conical silo after expansion can be automatically calculated by the script, reducing the dependence on manual work. Then, according to the outer arc length, side length, fan angle, steel plate width and single-piece optimal arc length reference value, the side length of each side wall section, the remaining side wall side length and the outer arc length of each side wall section after the steel typesetting of the fan-shaped annular side wall are obtained, and recorded as typesetting data, and the various data required for typesetting can be automatically calculated by the script, and then the typesetting scheme can be manually determined without manually formulating and drawing the typesetting diagram in CAD by drawing method, thereby reducing the typesetting difficulty, reducing the typesetting time, and increasing work efficiency. Finally, according to the layout data, the side wall layout drawing of the target conical silo equipment is directly output. The side wall layout drawing includes the main view of the target conical silo equipment, the fan-shaped side wall expansion drawing, the fan-shaped side wall layout division drawing, the sub-drawing after the fan-shaped side wall layout division and the layout description. The layout description includes the steel utilization rate corresponding to each section of the side wall after the steel layout division of the fan-shaped side wall.
