Description

Technical Field

[0001] The invention relates to the field of industrial equipment design, and in particular to a data-based automatic design and drawing method for a pump foundation. Background Art

[0002] In modern industrial design, pump equipment, as an important fluid conveying device, is widely used in chemical, petroleum, electric power and other industries. Its basic design has an important impact on its long-term operation stability and safety.

[0003] Traditional pump foundation design usually relies on manual experience, which is labor-intensive and prone to errors. In addition, the generation process of design and construction drawings is also cumbersome, and cross-software collaboration is not smooth. The current design process is that the process designer first completes the spatial layout of the pump equipment in the design software PDMS, and then outputs the pump equipment plan layout drawing. Finally, the structural designer manually completes the pump foundation design and detailed drawing in CAD based on the pump equipment plan layout drawing provided by the process designer and the pump equipment production drawing provided by the pump equipment manufacturer. The subsequent basic three-dimensional model also needs to be built through the detailed drawing. The whole process has low design efficiency, low quality and does not conform to the three-dimensional forward design concept.

[0004] With the application of design automation software, how to improve design efficiency and reduce human errors through data integration and automation tools has become an urgent problem to be solved. Therefore, it is particularly important to provide a data-based pump foundation automation design and drawing method that can effectively solve the problems in the existing technology. Summary of the invention

[0005] Aiming at the problems of difficulty, low efficiency and high error rate in the existing pump foundation design, a data-based automated design and drawing method for pump foundation is proposed. The efficiency of pump foundation design and the accuracy of drawing generation are improved through data-driven automated tools.

[0006] The technical solution of the present invention is: a data-based automatic design and drawing method for pump foundation, which specifically includes the following steps:

[0007] 1) The process designer completes the arrangement of the equipment pump according to the process requirements in the design software PDMS based on the pump model and motor model to be arranged, and then generates a .XML formatted capital provision file through the Pdms_Revit basic collaboration tool;

[0008] 2) The structural designer conducts secondary development of the Revit 3D modeling software, using the pump model and motor model as the association basis, and uses the design tool to parse the equipment attribute data in the investment document. During the parsing process, the corresponding pump model and motor model parameters and information are extracted and associated according to the equipment attribute parameters in the investment document to obtain the final equipment attribute data;

[0009] 3) Construct a pump basic family file in the Revit 3D modeling software based on the equipment attribute data. The pump basic family file construction process is to accurately match the model and motor model of each pump in the investment file with the pump model and motor model parameters, that is, the design tool performs accurate positioning of the basic family in the overall project model based on the pump equipment spatial positioning data contained in the investment file, and automatically supplements the detailed information parameters of the created basic instance;

[0010] 4) Structural designers use design tools to automatically complete the detailed arrangement of steel bars in the Revit 3D modeling software. Once modeling is completed, information is automatically retrieved and drawings are produced as needed.

[0011] Further, the pump model and motor model parameters and information in step 2) are derived from an established basic data table, and the basic data table is established by:

[0012] The following parameters should be recorded in detail in the basic data sheet: pump model, motor model, transverse and longitudinal boundary information of the base, base height K3, origin height H, and specifications of bolts at each position and corresponding dimensional positioning information;

[0013] In the parameters, the intersection of the inlet and outlet nozzles of the pump and motor process requirements is used as the coordinate origin, where the east and north directions are positive directions, and the west and south directions are negative directions. The coordinate type parameter information is supplemented according to the distance from the origin.

[0014] Compare the pump equipment manufacturing information provided by the pump equipment manufacturer with the pump model and motor model data in the established basic data table to ensure the completeness and accuracy of the basic data table.

[0015] Furthermore, the information contained in the capital raising file in step 1) includes: pump equipment positioning, directional space information, and process information of pump model, motor model, name, position number, remarks, and load.

[0016] Further, the pump basic family file construction process in step 3) is as follows:

[0017] Automatically retrieve and obtain relevant information about the pump foundation, including the horizontal and vertical boundary information of the pump base, the base height K3, the origin height H, and the specifications of each bolt and the corresponding dimensional positioning information;

[0018] Based on the obtained bolt coordinate positions, the design tool will automatically create bolt instances in the constructed pump foundation family file, and match the corresponding bolt holes for each bolt in accordance with the aforementioned bolt hole settings; after completing the creation of the bolt hole instances in the foundation family, the design tool will automatically calculate and determine the limit values ​​of the horizontal boundaries of the foundation extrusion body; based on this, the structural designer sets offsets for each boundary of the foundation to accommodate subsequent reinforcement layout or other space requirements;

[0019] When creating a pump foundation family file, the default positioning origin of the Revit 3D modeling software is set to be consistent with the origin of the equipment template pump, ensuring that the elevation of the top of the foundation in the family is correctly set;

[0020] Finally, after the pump foundation family shape is created, the design tool will automatically create the necessary reference lines and legends in the constructed pump foundation family, including hole legends, positioning lines, foundation positioning marks, and bolt legends to meet the needs of 3D model display and 2D drawing.

[0021] Further, the detailed arrangement of the steel bars in step 4): after the spatial layout design of the pump foundation is completed, the structural designer will proceed to the detailed arrangement of the steel bars, select the steel bar arrangement plan, and based on the structural design specifications, with a reinforcement ratio of not less than 0.002, the design tool automatically calculates the diameter and spacing specifications that meet the third-level steel bar standards. The structural designer verifies the generated data. If the parameters need to be adjusted, only the corresponding parameters need to be adjusted in the list, and finally confirm to complete the creation of the steel bar model.

[0022] Furthermore, in the step 4), the structural engineer uses a design tool developed based on Revit 3D modeling software to select the type of drawing frame, dimension line and direction of plan detail, and automatically creates and dimensions the plan drawing details; while creating the drawing details, the layout of the automatic view is performed simultaneously to complete the drawing generation.

[0023] A basic automated design method for pump equipment is provided, which establishes a basic pump data table, including pump model and motor model parameters and information with verified accuracy; process designers complete the layout of equipment pumps according to process requirements and generate pump and motor related process information; on 3D modeling software, the pump model and motor model are used as the correlation basis, the pump basic data table and the pump and motor related process information are called, and the pump equipment is constructed by automatic one-to-one matching.

[0024] The beneficial effects of the present invention are as follows: the data-based automated design and drawing method for pump foundations of the present invention realizes the automation of pump equipment foundation design by integrating data-driven and automated design processes, thereby improving design efficiency and accuracy.

[0035] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0036] like Figure 1 As shown, the present invention provides a data-based pump foundation automation design and drawing process diagram, which mainly adopts Figure 2 The PDMS 3D design software and Revit 3D building information modeling software shown in the figure cover the whole process from raising funds to creating data models and then drawing construction drawings, and realize seamless collaboration across software, significantly improving design efficiency and quality, and reducing design difficulty and cost. The implementation of the method specifically includes the following steps:

[0037] Step 1: Comparative analysis of pump equipment manufacturing data and basic data sheets:

[0038] First, the pump equipment manufacturing data provided by the pump equipment manufacturer must be compared with the pump model and motor model data in the existing basic data table. If the existing basic data table already contains the corresponding data for the corresponding pump model and motor model, the designer must verify whether the pump data in the basic data table is completely consistent with the information provided in the manufacturer's data. If it is found that the basic data table lacks data on the relevant pump model or motor model, the basic information of the pump should be supplemented in the basic data table in accordance with the established standard format to ensure the completeness and accuracy of the basic data table.

[0039] The following parameters should be recorded in detail in the basic data table: pump model, motor model, transverse and longitudinal boundary information of the base, base height K3, origin height H, and specifications of bolts at each position and corresponding dimensional positioning information. The pump model and motor model are used as key mapping conditions to index and retrieve other related parameters. Specifically, the combination of the pump model and motor model should be able to uniquely determine the transverse and longitudinal boundary information of the pump base, base height K3, origin height H, and specifications of bolts at each position and corresponding dimensional positioning information.

[0040] like Figure 3 The following is a common pump manufacturing diagram in pump equipment manufacturing information. Figure 4 The specific parameters and filling examples that need to be filled in the basic data table are displayed. When filling in coordinate type parameters, such as the positioning of each bolt and the positioning of the base boundary, the parameter filling should take the intersection of the inlet and outlet nozzles as the coordinate origin, that is, (0; 0), where E (east) and N (north) directions are positive directions, W (west) and S (south) directions are negative directions, and the coordinate type parameter information is supplemented according to the distance from the origin. The coordinate origin setting and direction setting in the basic design table refer to the conventional requirements of pump and motor processes, so as to avoid the re-verification of the position and direction when parsing the capital raising documents in the later step three.

[0041] Step 2: Generation and export of capital raising documents:

[0042] The process designers complete the layout of the equipment pumps according to the process requirements in the design software PDMS based on the pump models and motor models that need to be arranged. Then, they generate an XML-formatted design file through the Pdms_Revit basic collaborative tool. The exported design file mainly contains the following information: pump equipment spatial information (positioning, direction) and process information (pump model, motor model, name, position number, remarks, load).

[0043] Pump model and motor model: used as index conditions to obtain the base information, bolt specifications and positioning information in the basic data table. This information is used as the main basis for Revit to create a family.

[0044] Positioning and orientation of the pump: as the basis for the spatial positioning and rotation angle of the base family;

[0045] Equipment name: The name of the created family is based on the attribute parameters of the basic instance in the project;

[0046] Equipment tag: attribute parameter of the basic instance in the project;

[0047] Loads: calculation of embedded parts, attribute parameters of basic instances in the project and as component fields in detailed drawings;

[0048] Manufacturer information: attribute parameters of the basic instance in the project and as a component field in the detailed drawing description;

[0049] Fabrication drawings: Attribute parameters of the base instance in the project and as component fields in the detailed description.

[0050] Step 3: Complete the creation of the basic family according to the funding file:

[0051] Before starting the automated design of pump foundations, you must first confirm the type of foundation (such as embedded parts or bolt holes). Then, according to the project design requirements, set the corresponding bolt hole or embedded part size for different bolt specifications. This implementation example takes a foundation with three bolt hole types as an example. Figure 5 As shown in the figure, it shows a schematic diagram of the bolt hole settings corresponding to different bolt specifications in the project.

[0052] Next, the structural designer carried out secondary development based on the Revit 3D modeling software, using the pump model and motor model as the association basis, and used the design tools to parse the equipment attribute data in the capital provision file. During the parsing process, the corresponding parameters and information of step one were extracted and associated according to the equipment attribute parameters of step two to obtain the final equipment attribute data.

[0053] The pump foundation family file is established based on the equipment attribute data. The construction process is to accurately match the model and motor model of each pump in the capital file with the basic data table, so as to automatically retrieve and obtain the relevant information of the pump foundation, including the horizontal and vertical boundary information of the pump base, the base height K3, the origin height H, and the specifications of each bolt and the corresponding size positioning information. Figure 6 Demonstrates an example of data file reading.

[0054] Based on the obtained bolt coordinate positions, the design tool will automatically create bolt instances in the constructed Revit pump foundation family file, and match the corresponding bolt holes for each bolt in accordance with the aforementioned bolt hole settings. After completing the creation of the bolt hole instances in the foundation family, the design tool will automatically calculate and determine the limit values ​​of the horizontal boundaries of the foundation extrusion. Based on this, the structural designer can set specific offsets for each boundary of the foundation to accommodate subsequent reinforcement layout or other space requirements.

[0055] When creating a pump foundation family file, the default positioning origin setting of the Revit 3D modeling software is consistent with the origin of the equipment template pump, which can ensure that the elevation of the top of the foundation in the family is correctly set. Specifically, the top elevation of the foundation extrusion in the family = 0-origin height H (from the basic data table)-grouting layer thickness (user setting), and the initial extrusion thickness of the foundation is determined based on the positioning elevation of the equipment pump in the actual project, the parameter origin height H mapped in the basic data table, the set grouting layer thickness and the nearest floor elevation, that is, the initial extrusion thickness of the foundation = the positioning elevation of the equipment pump in the project-origin height H (from the basic data table)-grouting layer thickness (user setting)-nearest floor elevation (specifiable), and then according to the set cushion and grouting layer parameters, the creation of these two types of extrusions is completed synchronously.

[0056] Finally, after the pump foundation family shape is created, the design tool will automatically create the necessary reference lines and legends in the constructed pump foundation family, including hole legends, positioning lines, foundation positioning marks, bolt legends, etc., to meet the needs of 3D model display and 2D drawing.

[0057] Step 4: Positioning and parameter filling of the basic family:

[0058] After the pump foundation family is built, the design tool will accurately locate the pump foundation family in the overall project model based on the pump equipment spatial positioning data contained in the investment file. Subsequently, the design tool will automatically supplement the detailed information parameters of the created foundation instance, including but not limited to key attributes such as equipment number, equipment name, load bearing capacity, manufacturer information, and manufacturing drawing number. Figure 7 This is a schematic diagram of the automatic creation and arrangement process of the pump basic family according to an embodiment of the present invention.

[0059] Step 5: Detailed arrangement of reinforcement:

[0060] After the spatial layout design of the pump foundation is completed, the structural designer will proceed to the detailed layout of the reinforcement. The commonly used reinforcement layout scheme includes the composite configuration of the three-way reinforcement cage and stirrups. According to the structural design specifications, with a reinforcement ratio of not less than 0.002, the design tool automatically calculates the diameter and spacing specifications that meet the three-level reinforcement standards. The structural designer verifies the generated data. If the parameters need to be adjusted, just adjust the corresponding parameters in the list, and finally confirm to automatically complete the creation of the reinforcement model in the revit 3D modeling software project. Figure 8 It is a schematic diagram of the steel bar arrangement interface of an embodiment of the present invention.

[0061] Step 6: Generation and annotation of detailed views:

[0062] Structural engineers use design tools developed based on Revit 3D modeling software to automate the process of creating detailed drawings. First, the structural engineer switches to the basic plan layout view in Revit 3D modeling software, then selects the frame type, dimension line type, and the direction of the plan detail (real layout direction or initial direction without angle) in the design tool, and finally picks up the basic instance to automate the creation of plan views and section views, and automatically completes dimension creation and text annotations.

[0063] In the drawing stage, in order to meet the specific requirements of the project, structural engineers can use design tools in Revit 3D modeling software to automatically generate corresponding plan views and section views for each basic instance. In this process, the design tool will customize the dimensioning and text annotation settings for different view types.

[0064] During the dimension line creation process, the design tool automatically analyzes the point, line, and surface structure in each base instance. This includes the base entity itself, the attached components on the foundation (such as bolts or embedded parts), and specific reference locations (such as location lines and elevation lines). Based on the geometric characteristics and design requirements of the object, the design tool automatically selects the appropriate acquisition method and divides these objects into different groups for efficient dimension line generation.

[0065] In the generation of the plan view, the design tool focuses on the horizontal and vertical dimensioning, and automatically generates two dimension lines in each direction. These dimension lines cover the boundary lines of the basic entities, the positioning lines of the bolt hole centers, and the positioning lines of related equipment. In this way, all key dimensions and positional relationships are displayed in a highly automated form. In addition, text annotations are also automatically generated in the Revit 3D modeling software through the design tool, including positioning marks, the number of bolts or embedded parts and their specifications. All text is clearly marked on the plan view in the form of leaders to avoid missing information and misjudgment. Fig. 9 It is a schematic plan view of an embodiment of the present invention.

[0066] In terms of the generation of section views, it is also automatically completed in the Revit 3D modeling software through design tools. In this process, the design tool will focus on marking the combined dimensions of the positioning line, elevation line, foundation surface, and bottom surface of the bolt hole. The design tool will automatically calculate and generate the corresponding dimension lines based on the structural characteristics and design requirements of the foundation instance. At the same time, the text annotation part is also processed by the system, and the content mainly involves the relevant information of the positioning mark and the grouting layer, which is also marked by the lead line. These automated processing processes greatly improve the efficiency and accuracy of drawing generation, while reducing the potential errors caused by manual operation. Fig.10 It is a schematic cross-sectional view of an embodiment of the present invention.

[0067] Step 7: Drawing layout and output:

[0068] The layout and creation of detail views in drawings are carried out simultaneously. Select the frame type in the design tool and fill in the drawing name, and the created plan and section detail views will be automatically added to the frame.

[0069] In the process of automatic construction drawing generation, once the views are created, the next step is to integrate and optimize the layout of these views. Select the frame type in the design tool and fill in the drawing name. The views of each instance will be added to the frame in order from left to right and from top to bottom.

[0070] Through the above professional automated process, designers can ensure the efficient generation of drawings while maintaining the professionalism and accuracy of the drawings. This intelligent design tool not only improves work efficiency, but also reduces the possibility of human error, providing the construction team with high-quality construction drawings.

[0071] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
