Description

Technical Field

[0001] The present invention relates to the technical field of construction, and particularly relates to a method, device and terminal device for formulating a layout plan for the side wall of a conical silo device. Background Art

[0002] The conical silo device is a commonly used device in fields such as metallurgy. During the construction process of the conical silo device, it is usually necessary to manually calculate the developed size of the side wall of the conical silo device, and then manually calculate the number of segments required for dividing the developed side wall of the silo according to the width of the steel plate and the number of sub-blocks required for each segment after segmentation. Then, according to the number of segments and sub-blocks, manually use the drawing method in CAD to draw the layout drawing and cutting blanking drawing of the steel plate, and finally splice and weld small steel plates into the side wall of the silo.

[0003] The entire layout and blanking process is highly dependent on manual labor. For example, when calculating the developed size of the side wall of the conical silo, manual calculation is required. After development, a manual layout plan needs to be formulated, and after formulating the layout plan, it is necessary to manually use the drawing method in CAD to draw the layout drawing and blanking drawing. Generally speaking, the manual workload is large, the time consumption is long, it is highly dependent on work experience, the calculation difficulty is high, and it is difficult to accurately control the utilization rate of the steel plate.

[0053] Next, the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0054] See Figure 1 , which shows the implementation flowchart of the method for formulating the side wall layout plan of the conical silo equipment provided by an embodiment of the present invention, and is described in detail as follows:

[0055] Step S101, based on the equipment drawing of the target conical silo equipment, obtain the geometric dimension parameters in the equipment drawing, and generate the target 3D model corresponding to the target conical silo equipment according to the geometric dimension parameters.

[0056] Exemplarily, in combination with Figures 2 to 3 , the target three-dimensional model of the target conical silo equipment can be generated using Dynamo scripts in Revit software. The target three-dimensional model of the target conical silo equipment can be automatically generated in Revit software according to dimensions such as the wide opening radius, narrow opening radius, cone height, and wall thickness in the equipment drawings, and the drawing dimensions are input into the model software to generate the model. In this embodiment, the main purpose is to generate the model for preview and provide basic geometric information for the following steps, without having to view the drawings for input.

[0057] Step S102: Based on the target three-dimensional model, obtain the outer arc length, side length, and sector angle of the fan-shaped side wall after the target conical silo equipment is unfolded.

[0058] Optionally, step S102 may include:

[0059] Extract the radius of the lower bottom surface of the frustum of a cone, the first side length, and the second side length in the target three-dimensional model.

[0060] Among them, the radius of the lower bottom surface of the frustum of a cone is half of the longer base of the isosceles trapezoid corresponding to the front view of the target three-dimensional model. The first side length is the distance from the intersection point of the extended lines of the two waists of the isosceles trapezoid to any end point of the longer base of the isosceles trapezoid. The second side length is the distance from the intersection point of the extended lines of the two waists of the isosceles trapezoid to any end point of the shorter base of the isosceles trapezoid.

[0061] According to the radius of the lower bottom surface of the frustum of a cone, obtain the outer arc length of the fan-shaped side wall after the target conical silo equipment is unfolded.

[0062] Calculate the difference between the first side length and the second side length to obtain the side length of the fan-shaped side wall after the target conical silo equipment is unfolded.

[0063] According to the outer arc length and the first side length, obtain the sector angle of the fan-shaped side wall after the target conical silo equipment is unfolded.

[0064] In combination with Figure 4 shown, in this embodiment, the basic geometric parameters can be extracted by selecting the model. As Figure 5 and Figure 6 shown, the extracted geometric parameters may include the radius of the circular top of the cone (that is, the radius of the lower bottom surface of the frustum of a cone. Since the steel plate used in the target three-dimensional model has a certain thickness, when extracting the radius of the lower bottom surface of the frustum of a cone, it can be calculated according to the middle position of the steel plate thickness), the total side length from the intersection point at the bottom of the cone to the top (that is, the first side length), and the side length from the intersection point at the bottom of the cone to the conical bottom edge (i.e., the second side length), after the cone is unfolded, it becomes a sector, and from this, the total length of the sector side (i.e., the side length of the fan-shaped annular side wall after the target conical silo equipment is unfolded) can be simply calculated as , the outer arc length of the sector after the top is unfolded (i.e., the outer arc length of the fan-shaped annular side wall after the target conical silo equipment is unfolded) is , the sector angle is .

[0065] Step S103, according to the outer arc length, side length, sector angle, steel plate width, and the reference value of the best arc length per piece, obtain the side length of each section of the side wall, the remaining side length of the side wall, and the outer arc length of each section of the side wall after the steel plate layout division of the fan-shaped annular side wall, which is recorded as layout data.

[0066] Among them, the steel plate width is the width of the steel plate used for the steel plate layout division of the fan-shaped annular side wall.

[0067] Optionally, step S103 may include:

[0068] Take the outer arc length as the outer arc length of the current section of the side wall during the steel plate layout division of the fan-shaped annular side wall, and according to the outer arc length of the current section of the side wall and the reference value of the best arc length per piece, obtain the number of blocks of the current section of the side wall during the steel plate layout division of the fan-shaped annular side wall.

[0069] According to the first side length, sector angle, number of blocks of the current section of the side wall, and steel plate width, obtain the side length of the current section of the side wall.

[0070] According to the side length and the side length of the current section of the side wall, obtain the remaining side length of the side wall in the fan-shaped annular side wall except for the current section of the side wall.

[0071] According to the side length of the current section of the side wall and the remaining side length of the side wall, draw the outer arc of the remaining side wall in the fan-shaped annular side wall except for the current section of the side wall, and obtain the outer arc length of the next section of the side wall according to the outer arc.

[0072] Take the outer arc length of the next section of the side wall as the new outer arc length of the current section of the side wall, and repeat the steps of "according to the outer arc length of the current section of the side wall and the reference value of the best arc length per piece, obtain the number of blocks of the current section of the side wall during the steel plate layout division of the fan-shaped annular side wall" and the subsequent steps until the remaining side length of the side wall is 0, and obtain the layout data.

[0073] Optionally, according to the first side length, sector angle, number of blocks of the current section of the side wall, and steel plate width, obtaining the side length of the current section of the side wall includes:

[0074] According to , obtain the side length of the current section of the side wall;

[0075] Among them, is the The side length of the side wall of the segment is the side length of the sector corresponding to the remaining side wall after the segment side wall is divided from the fan-shaped side wall, which is the first side length, is the width of the steel plate, is the sector angle, is the number of blocks of the segment side wall.

[0076] Optionally, according to the side length and the side length of the current segment side wall, obtain the side length of the remaining side wall in the fan-shaped side wall except the current segment side wall, including:

[0077] According to , obtain the side length of the remaining side wall in the fan-shaped side wall except the current segment side wall;

[0078] Among them, is the side length of the remaining side wall in the fan-shaped side wall except the segment side wall, is the side length, is the side length of the segment side wall.

[0079] As Figure 7 shown, then enter the data input interface, start inputting typesetting data, and the reference value of the best arc length of a single block after segmentation is displayed in the interface (exemplarily, it can be obtained from the feedback of workers with construction experience). According to the reference value of the best arc length of a single block and the actual construction situation, it can be comprehensively judged how many blocks a certain segment should be divided into (for example, if the construction is tense, one less block can be divided to reduce the cutting seam). The arc length of the first segment (that is, the outer arc length of the fan-shaped side wall after the target conical silo equipment is unfolded) is already displayed in the input interface. When dividing the first segment, it is calculated according to this value. The next interface (that is, Figure 8 ) will display the arc length (that is, the outer arc length of the next segment side wall) of the next segment. When dividing the next segment, it is calculated according to . Each time the script runs, only a certain segment can be divided (because only the outer arc length of the next segment can be calculated at a time). Running multiple times can complete all segmentations. The width of the steel plate can be input according to the actual on-site procurement.

[0080] Exemplarily, when the segmentation data of a certain segment is input, the side length of the side wall of this segment will be calculated, which is: , and through , , the side length of the remaining side wall can be simply calculated. Then, the geometric figure can be directly drawn in Dynamo by inputting commands with the calculated parameters. By , , , the expanded sector can be drawn. By the number of evenly divided blocks , the small sectors after division can be drawn. By , , the outer arc of the next side wall can be drawn. Finally, the length of the outer arc of the next side wall can be directly measured through the command . Thus, various data required for automatic typesetting can be calculated through the script, and then the typesetting scheme can be determined manually, reducing the typesetting difficulty, shortening the typesetting time, and increasing work efficiency.

[0081] As Figure 8 shown, finally, the data display interface can be entered. This interface can only be used for data display. After the typesetting scheme is completed, the save button can be clicked on this interface and the path can be set to save the typesetting scheme data, providing typesetting data for subsequent steps. Among them, Figure 8 the width W of the steel plate and the number of evenly divided blocks n (i.e., the number of blocks for the th side wall segment ) can be directly introduced from the data in the previous interface. The sector arc length l is the data calculated in the previous interface. Among them, the arc length of the next segment can be placed at the bottom of this column. When it is divided into the third segment, the arc length of the fourth segment is automatically calculated and the value is placed in the fourth row of the sector arc length l column. Since there is no other data in this row, other cells are blank. The remaining sector side length Sn is the data calculated in the previous interface , and is placed here to estimate approximately how many more segments there will be subsequently. When the remaining sector side length Sn is 0, it means there is no remainder and the current is the last segment. Figure 8 The n-segment remaining side lengths in correspond to the side lengths of the th side wall segment.

[0082] Step S104: According to the typesetting data, output the side wall typesetting drawing of the target conical silo equipment. The side wall typesetting drawing includes the front view of the target conical silo equipment, the developed drawing of the fan-shaped side wall, the typesetting division drawing of the fan-shaped side wall, the sub-drawing after the typesetting division of the fan-shaped side wall, and the typesetting instructions. The typesetting instructions include the steel utilization rate corresponding to each side wall segment after the steel typesetting division of the fan-shaped side wall.

[0083] Optionally, the generation process of the steel utilization rate may include:

[0084] According to , calculate the steel utilization rate corresponding to the th side wall segment after the steel typesetting division of the fan-shaped side wall.

[0085] Among them, is the steel utilization rate corresponding to the th side wall after the steel plate layout division of the fan-shaped side wall, is the total area of the th side wall divided from the fan-shaped side wall, is the width of the steel plate, is the length of the steel plate required for the th side wall, is the number of blocks of the th side wall, is the side length of the sector corresponding to the remaining side wall after the th side wall is divided from the fan-shaped side wall, is the sector angle.

[0086] As Figure 9 shown, after running step S104, a data input interface can appear. In this data input interface, there are respectively: 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 description text of the placement plan. Among them, "selecting the view for placing the description text of the placement plan" is due to software limitations. The text of the plan description needs to be placed in a Revit software plan 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 , the width of the steel plate , the number of blocks , the outer arc length of the side wall , the side length of the remaining side wall , the side length of the nth side wall can be obtained. The function of "selecting the silo model for which drawings need to be generated" is similar to the previous step and can be used to extract the geometric parameters of the model, such as: the radius of the conical top circle , the radius of the conical bottom circle , the total length of the side from the conical bottom intersection point to the top , the side length from the conical bottom intersection point to the conical bottom edge , the height H from the conical bottom plane to the top plane. After the cone is unfolded, it is a sector, and from this, the total side length of the fan-shaped side wall , the outer arc length of the fan-shaped side wall after unfolding , the inner arc length of the fan-shaped side wall , and the sector angle can be simply calculated.

[0087] Then the script continues to run and draws the unfolded plane geometric figure through parameters (the figure can be directly obtained by entering commands). First, according to , , H draw the dimension diagram of the conical silo (i.e., the front view of the target 3D model), and then according to , , draw the developed view of the fan-shaped side wall (i.e., the developed view of the fan-shaped side wall), and then according to , the side length of the side wall in n segments , the number of divided blocks , draw the layout division diagram of the fan-shaped side wall (i.e., the diagram after the layout division of the fan-shaped side wall), then according to , , , draw each small sector of each specification after segmentation and division (i.e., the sub-diagram after the layout division of the fan-shaped side wall). At this time, the drawing work is completed, and then some drawing annotation work can be manually supplemented by personnel. It should be noted that the cutting plan is not drawn by the script and can be obtained by copying and rotating the sub-diagram after the layout division of the fan-shaped side wall. Finally, the script will also generate a text description of the layout plan (i.e., the layout description). The layout description can include the number of segments divided, the number of blocks in each segment, the length and width of the steel plate required for each segment during blanking, the utilization rate of the plate during blanking (since the blanking steel plate is rectangular and the finished product is fan-shaped, there will be waste at the corners of the steel plate, and usually this part of the waste is difficult to utilize, that is, the calculated steel utilization rate), and the length of the cutting seam.

[0088] In this embodiment, the material utilization rate can be directly obtained through the utilization rate of the plate. When the utilization rate is too low, the layout plan can be optimized to improve the utilization rate of the plate and create higher economic benefits. Moreover, since the blanking process is mainly to cut fan-shaped finished products on a rectangular steel plate, calculating the length of the cutting seam can help construction personnel understand the blanking workload, estimate the working time, and can also be combined with the steel plate utilization rate to optimize the layout plan (increasing the utilization rate will increase the number of divided blocks, and the increase in the number of blocks will lead to a longer cutting seam and an increase in the blanking time).

[0089] Among them, the number of segments and divided blocks, the length of the steel plate, and the width of the steel plate can be directly obtained from the existing parameters (among them, the length of the steel plate can be obtained during the calculation of the steel utilization rate), and will not be described. The main calculation process of the steel plate utilization rate is the area of the fan-shaped side wall divided by the area of the blanking steel plate. The area of the fan-shaped side wall can be directly measured by the command through the small fan-shaped geometric figures after the previous step of division. The width of the steel plate is known, and here the length of the steel plate is mainly calculated. As Figure 10 shown, since the small sectors are arranged in a staggered manner, one positive and one negative, on the steel plate, the calculation of the length of the steel plate is relatively complex. Here, it is assumed that the length of the steel plate just meets the fan-shaped arrangement (i.e., the edge of the steel plate is close to the fan), then we can get:

[0090] ;

[0091] Among them, Figure 10 the L in corresponds to the length of the steel plate , Figure 10 the b in corresponds to , Figure 10 the a in corresponds to , Figure 10 the c in corresponds to , Figure 10 the x in corresponds to , Figure 10 the m in corresponds to , the length of the steel plate can be obtained through this process , and finally the utilization rate of the steel is obtained, which is the total area of each side wall after segmentation divided by the area of the steel plate.
