Description

Technical Field

[0001] This invention belongs to the field of three-dimensional design and automated processing, specifically relating to a method for automatically generating the anchoring position and material information of pipe supports inside a cold box. Background Technology

[0002] In traditional cold box piping construction, the positioning of pipe supports typically relies on manual measurement due to a lack of effective digital and precise methods. This approach has several drawbacks. First, manual measurement is inherently prone to error and is extremely time-consuming. Second, the varying experience levels of construction personnel often lead to inaccurate judgments of support placement, resulting in significant deviations between the construction outcome and design requirements. Pipe support positional deviations frequently occur during cold box piping construction, not only affecting construction progress but also potentially threatening the stability and safety of the piping system.

[0003] In addition, the designed pipe rack information needs to be collected and organized to generate a detailed and accurate pipe rack information table to facilitate subsequent material cutting and processing. However, in the traditional approach, this information also needs to be manually summarized and statistically analyzed, which is an extremely tedious process that consumes a lot of manpower and is difficult to avoid errors.

[0004] Therefore, how to improve the accurate acquisition of rooting position information and material information in the design of tube racks inside cold boxes, and reduce the workload required for manual measurement and summarization, is one of the technical problems that urgently need to be solved. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art and to provide a method for automatically generating the rooting position and material information of the pipe support inside the cold box.

[0006] The specific technical solution adopted in this invention is as follows: A method for automatically generating information on the anchoring location and material usage of pipe supports inside a cold box, comprising: S1. In AVEVA E3D, various types of standard pipe rack elements are constructed based on ATTA elements. The structure of a standard pipe rack element includes a support body composed of rods, diagonal braces for improving the strength of the support body, and blocks for limiting and fixing the pipes to the support body. For each standard pipe rack element, a point set and shape set are assigned according to its three-dimensional structure. At the same time, the structural parameters and materials of the support body, diagonal braces, and blocks are predefined as designable variables. S2. Construct a 3D model of the target cold box and its internal piping in AVEVA E3D. Then, according to the design requirements, select the appropriate type of standard pipe support element and add it to the pipe for each location where pipe supports need to be set. Assign values ​​to all designable variables and calculate the spatial coordinates of each point in the point set based on the assigned designable variables and spatial geometric relationships. After adding all standard pipe support elements to the 3D model, a 3D model of the pipe support inside the cold box is formed. S3. After receiving the user's input generation command, select all standard pipe support components from the 3D model of the pipe support inside the cold box, and traverse the selected standard pipe support components. Extract the corresponding pipe support index information, the rooting position information of the pipe support in the cold box, and the material information required to process the pipe support from the attribute table of each standard pipe support component. Output the structured pipe support information table according to the preset format to guide the manufacturing and installation of the pipe support.

[0007] Preferably, the types of standard pipe rack components include at least frame-type pipe racks, clamp-type pipe racks, U-bolt-type pipe racks, and bracket-type pipe racks.

[0008] Preferably, the designable variables include at least the distance from the rooting point of the support body on the attachment to the axis of the fixed pipe, the inclination angle of the diagonal brace, the installation gap between the support body and the fixed pipe, the installation gap between the stop and the fixed pipe, whether to set a binary classification mark for the stop, and the material of the support body and the diagonal brace.

[0009] Preferably, the inclination angle of the diagonal brace is distinguished by positive and negative signs, where a negative inclination angle represents support from below, a positive inclination angle represents suspension from above, and an inclination angle of 0 represents no diagonal brace is installed.

[0010] Preferably, the material of the stop block is the same as that of the pipe being fixed, and it is directly fixed to the outer surface of the pipe being fixed.

[0011] Preferably, when the standard pipe support element is a frame-type pipe support, a clamp-type pipe support, or a U-bolt-type pipe support, two stops are respectively provided along the axial direction of the pipe to be fixed, which clamp and fix the pipe to be fixed on the support body, thereby limiting the relative displacement of the pipe along the axial direction. When the standard pipe support element is a bracket-type pipe support, the stop is only set at the cantilever end of the support body to restrict the pipe from sliding off the support body.

[0012] Preferably, in the three-dimensional model of the tube rack inside the cold box, all information of each standard tube rack element is stored in the attribute table of that element in a structured manner. Step S3 is performed by extracting information from the attribute table and outputting the structured tube rack information table through a secondary development program in AVEVA E3D.

[0013] Preferably, the index information of the pipe support includes the pipe support number, the pipeline number it is located on, and the specification code.

[0014] Preferably, the rooting position information of the pipe support in the cold box includes the coordinates of the rooting point of the support body on the attachment, the model of the support body, the coordinates of the rooting point of the diagonal brace on the attachment, the model of the diagonal brace, and the installation information of the stop block.

[0015] Preferably, the material information required for processing the pipe support includes the processing dimensions of each structural component after the pipe support has been disassembled.

[0016] Compared with the prior art, the present invention has the following advantages: This invention, through the design and secondary development of built-in component functions in 3D design software, achieves the simulation of pipe supports within a cold box and efficiently outputs a directly usable pipe support information table. Specifically, based on the underlying logic of the software's built-in ATTA component, this invention utilizes a series of parameterized components to create a pipe support model with adjustable parameters. Designers can call custom components to establish a detailed pipe support model within the cold box according to relevant standards and specifications, and set key information for the pipe supports. When information aggregation and statistics are required, the secondary development program can automatically extract all pipe support indices, rooting positions, and material information from the 3D model, outputting a structured pipe support information table. This invention, through parametric modeling and secondary development, achieves rapid, visual modeling and automatic data output for pipe support design, significantly improving design accuracy, intuitiveness, and work efficiency, while reducing manual labor and errors.

Detailed Implementation

[0018] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Technical features in various embodiments of the present invention can be combined accordingly without mutual conflict.

[0019] In the description of this invention, it should be understood that when an element is considered to be "connected" to another element, it can be a direct connection to the other element or an indirect connection, i.e., an intermediate element exists. Conversely, when an element is said to be "directly" connected to another element, no intermediate element exists.

[0020] In the description of this invention, it should be understood that the terms "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0021] like Figure 1 As shown, in a preferred embodiment of the present invention, a method for automatically generating the anchoring position and material information of the pipe support inside the cold box is provided, the specific steps of which are described in S1 to S3 below.

[0022] S1. In AVEVA E3D, various types of standard pipe rack elements are constructed based on ATTA elements. The structure of a standard pipe rack element includes a support body composed of rods, diagonal braces used to improve the strength of the support body, and blocks used to limit and fix the pipes to the support body. For each standard pipe rack element, a point set and shape set are assigned according to its three-dimensional structure. At the same time, the structural parameters and materials of the support body, diagonal braces, and blocks are predefined as designable variables.

[0023] It should be noted that AVEVA E3D is an existing 3D collaborative design platform, while ATTA is a component type built into AVEVA E3D. ATTA components can be used as templates to construct different standard pipe support components. Furthermore, ATTA components support the addition of custom attributes not found in the standard component library. Therefore, this invention can construct corresponding standard pipe support components based on ATTA components according to the type of pipe support, and provide design variables that can be flexibly adjusted by the designer during the design process for various standard pipe support components. ATTA components can set point sets, shape sets, and parametric design variables. Point sets are the collection of key points of the pipe support, used to indicate the position and anchoring location of the pipe support; shape sets are the collection of geometric shapes of the pipe support, used to visually reflect the actual shape of the pipe support; parametric design variables allow the designer to assign values ​​to adjust the pipe support model. After setting the point sets and shape sets, point set and shape set rules can be defined. Point set and shape set rules refer to a set of logical judgment statements and mathematical operations. These calculation rules allow for the calculation of the position and orientation of point sets, the geometry of shape sets, and other parameters based on the design variables input by the designer, thus creating a parameter-driven pipe rack model. Designers can control the positions of pipe rack positioning points and rooting points, as well as the geometry of the pipe rack, by setting designable variables and using the point and shape set rules configured in the ATTA components. This ensures the pipe rack model is intuitive and the positioning points are accurate.

[0024] To achieve the objectives of this invention, the designable variables in each standard pipe support element generally include at least the distance from the anchoring point of the support body on the attachment to the axis of the fixed pipe, the inclination angle of the diagonal brace, the installation gap between the support body and the fixed pipe, the installation gap between the stop and the fixed pipe, whether a binary classification mark is provided for the stop, and the materials of the support body and the diagonal brace. However, these are only some necessary designable variables, and more designable variables or default variables can be introduced according to actual design needs.

[0025] In embodiments of the present invention, the standard pipe support elements include one or more of the following: frame-type pipe supports, clamp-type pipe supports, U-bolt-type pipe supports, and bracket-type pipe supports, each corresponding to one of four different types of pipe supports. In principle, a diverse range of standard pipe support element types should be defined according to actual design requirements to facilitate selection by designers. Furthermore, since pipes can be vertical or horizontal, pipe supports can also be configured to provide both vertical and horizontal pipe supports.

[0026] It should be noted that the type of stop on the pipe support may vary depending on the type of pipe support. When the standard pipe support element is a frame-type pipe support, clamp-type pipe support, or U-bolt-type pipe support, two stops are respectively provided along the axial direction of the pipe being fixed, clamping and fixing the pipe to the support body and restricting the relative displacement of the pipe along the axial direction; while when the standard pipe support element is a bracket-type pipe support, the stops are only provided at the cantilever end of the support body, preventing the pipe from sliding off the support body.

[0027] In embodiments of the present invention, the structure of the frame-type pipe support for fixing vertical pipes is as follows: Figure 2 As shown, the main body of the support is a bracket welded together from two parallel long rods and two parallel short rods. The two long rods serve as legs for fixing to the attached object, while the two short rods are located at the ends of the two long rods. The four rods form a square frame through which the fixed pipe passes. If diagonal bracing is used, it needs to be installed separately for the two long rods, with the support point located at the midpoint of the rod segment within the square frame. Diagonal bracing can be divided into two types: supporting from below and suspending from above, and can also be omitted depending on actual needs. The material of the stop blocks is generally the same as that of the fixed pipe, and they are directly welded to the outer surface of the fixed pipe. Two stop blocks can be installed along the axial direction of the fixed pipe to clamp and fix the fixed pipe to the main body of the support, restricting the relative displacement of the pipe along the axial direction. Of course, the existence of these two stop blocks is a design variable; the designer can choose to retain one, two, or none of them, depending on the designer's decision during the design optimization phase.

[0028] Additionally, see also Figure 2 As shown, for this type of frame-type pipe rack, the center points of the two legs on the attachment surface are points A and A', while the center point of the diagonal brace on the attachment surface is point B. Therefore, among the design variables of the ATTA element, the distance from the anchor point of the support body on the attachment to the axis of the fixed pipe is L1, the inclination angle of the diagonal brace is α, the installation gap between the support body (actually a square frame) and the fixed pipe is Δw1, the installation gap between the stop and the fixed pipe is Δw2, the binary classification mark for whether or not a stop is set is DDES and EDES (the two marks can represent whether or not side stops are set), and the material of the support body and the diagonal brace is GDES. The inclination angle of the diagonal brace is distinguished by positive and negative signs, where a negative inclination angle represents support from below, a positive inclination angle represents suspension from above, and an inclination angle of 0 means no diagonal brace is set. If diagonal brace is selected, the length of the diagonal brace is L2.

[0029] like Figure 3 As shown, an ATTA element based on AVEVA E3D is constructed in an embodiment of the present invention. Figure 2Standard pipe rack components for medium-frame pipe racks.

[0030] Similarly, in embodiments of the present invention, the structure of the frame-type pipe support for fixing horizontal pipes is as follows: Figure 4 As shown, its basic structure and designable variables are similar to those of a frame-type pipe rack used to fix vertical pipes, with the main difference being the posture of the main body of the support.

[0031] like Figure 5 and Figure 6 The diagrams show structural schematics of clamp-type pipe supports used for fixing vertical and horizontal pipes, respectively. The basic structures and design variables of both are similar, with the main difference being the orientation of the support body. The main body of this type of clamp-type pipe support is a single straight rod, with a ring-shaped clamp fitted to the side of the cantilevered section. This ring-shaped clamp secures the pipe in a snap-fit ​​manner. If diagonal bracing is used, it can be directly connected to the straight rod. Similarly, stops can be installed on both sides of the pipe; whether or not to install stops on both sides is an independently designable variable.

[0032] For this type of clamp-type pipe support, the center point of the fixed end of the straight member on the attachment surface is point A, while the center point of the diagonal brace on the attachment surface is point B. Therefore, in the design variables of the ATTA element, the distance from the anchor point of the support body on the attachment to the axis of the fixed pipe is L1; the inclination angle of the diagonal brace is α; the installation gap between the support body (actually a ring clamp) and the fixed pipe is Δw1; the installation gap between the stop and the fixed pipe is Δw2; the binary classification markers for whether or not a stop is installed are DDES and EDES (the two markers can represent whether or not side stops are installed); and the material of the support body and the diagonal brace is GDES. The inclination angle of the diagonal brace is distinguished by positive and negative signs, where a negative inclination angle represents support from below, a positive inclination angle represents suspension from above, and an inclination angle of 0 indicates that no diagonal brace is installed. If diagonal brace is selected, the length of the diagonal brace is L2.

[0033] like Figure 7 and Figure 8 The diagrams show structural schematics of U-bolt pipe supports used for fixing vertical and horizontal pipes, respectively. The basic structures and design variables of both are similar, with the main difference being the orientation of the support body. The support body of this type of U-bolt pipe support is a single straight rod, with a U-bolt fitted to the side of the cantilevered section. The pipe is secured using a snap-fit ​​method with the U-bolt. If diagonal bracing is used, it can be directly connected to the straight rod. Similarly, stops can be installed on both sides of the pipe; whether or not to install stops on both sides is an independently designable variable.

[0034] For this type of U-bolt pipe support, the center point of the fixed end of the straight member on the attachment surface is point A, while the center point of the diagonal brace on the attachment surface is point B. Therefore, in the design variables of the ATTA element, the distance from the anchor point of the support body on the attachment to the axis of the fixed pipe is L1; the inclination angle of the diagonal brace is α; the installation gap between the support body (actually a U-bolt) and the fixed pipe is Δw1; the installation gap between the stop and the fixed pipe is Δw2; the binary classification markers for whether or not a stop is installed are DDES and EDES (the two markers can represent whether or not side stops are installed), and the material of the support body and the diagonal brace is GDES. The inclination angle of the diagonal brace is distinguished by positive and negative signs, where a negative inclination angle represents support from below, a positive inclination angle represents suspension from above, and an inclination angle of 0 indicates no diagonal brace is installed. If diagonal brace is selected, the length of the diagonal brace is L2.

[0035] like Figure 9 The diagrams show structural schematics of bracket-type pipe supports used to fix horizontal pipes. The main body of this type of support is a single straight rod, and the pipe is placed directly on the cantilevered end of the rod. However, to prevent the pipe from slipping, a stop is fixed to the upper surface of the cantilevered end of the straight rod. If diagonal bracing is used, it can be directly connected to the straight rod.

[0036] For this type of bracket-type pipe support, the center point of the fixed end of the straight rod on the attachment surface is point A, while the center point of the diagonal brace on the attachment surface is point B. Therefore, in the design variables of the ATTA element, the distance from the anchor point of the support body on the attachment to the axis of the fixed pipe is L1; the inclination angle of the diagonal brace is α; the installation gap between the support body (actually a straight rod) and the fixed pipe is Δw1; the installation gap between the stop block and the fixed pipe is Δw2; the binary classification mark for whether a stop block is installed is EDES; the material of the support body and the diagonal brace is GDES; and the height of the stop block is h (different pipe diameters require different height stop blocks). The inclination angle of the diagonal brace is distinguished by positive and negative signs, where a negative inclination angle represents support from below, a positive inclination angle represents suspension from above, and an inclination angle of 0 indicates no diagonal brace is installed. If diagonal brace is selected, the length of the diagonal brace is L2.

[0037] Based on the different types of standard tube rack components built in AVEVA E3D, they can be used to build and optimize the 3D model of the tube rack inside the cold box. This will be explained in detail below.

[0038] S2. Construct a 3D model of the target cold box and its internal piping in AVEVA E3D. Then, according to the design requirements, select the appropriate type of standard pipe support element for each location where pipe supports need to be set and add it to the pipe. Assign values ​​to all designable variables and calculate the spatial coordinates of each point in the point set based on the assigned designable variables and spatial geometric relationships. After adding all standard pipe support elements to the 3D model, a 3D model of the pipe support inside the cold box is formed.

[0039] It should be noted that the specific location and type of standard pipe support element selected in this invention are determined based on design requirements. If a pre-designed document exists, the designer can directly add elements according to the requirements in the document. If no pre-designed document exists, the designer needs to adjust and optimize according to relevant design standards or experience. This invention does not limit how to determine the location of the pipe support, how to select the type of standard pipe support element, or how to determine each design variable. Since point sets and shape sets are pre-defined for each standard pipe support element, each point set and shape set can calculate its position, orientation, and geometric shape based on the design variable parameters and spatial geometric relationships input by the designer, according to its own calculation rules.

[0040] S3. After receiving the user's input generation command, select all standard pipe support components from the 3D model of the pipe support inside the cold box, and traverse the selected standard pipe support components. Extract the corresponding pipe support index information, the rooting position information of the pipe support in the cold box, and the material information required to process the pipe support from the attribute table of each standard pipe support component. Output the structured pipe support information table according to the preset format to guide the manufacturing and installation of the pipe support.

[0041] It should be noted that in the 3D model of the tube rack inside the cold box saved in AVEVA E3D software, all the information of each standard tube rack element is stored in the attribute table of that element in a structured manner. Therefore, the above S3 step actually requires writing a secondary development program in AVEVA E3D to extract the information from the attribute table and output the structured tube rack information table.

[0042] In AVEVA E3D, you can typically add buttons through software customization, pointing to a secondary development program. This program can use a .pmlmac file. The secondary development program needs to be launched based on user commands. After launch, it filters all standard pipe rack components from the 3D model of the cold box's pipe rack. Generally, you can directly extract ATTA components with the STYPE attribute equal to 'SUP' from the model and add them to the set to be traversed as standard pipe rack components. Then, you traverse these standard pipe rack components, extracting the required information one by one.

[0043] The information to be extracted in this invention includes three categories: pipe support index information, the anchoring position of the pipe support in the cold box, and the material information required to process the pipe support. The specific information content can be optimized according to actual needs.

[0044] In an embodiment of the present invention, the index information of the pipe support includes the pipe support number, the pipeline number (the number of the fixed pipe), and the specification code (different pipe supports can be customized according to internal requirements or defined by recognized standards).

[0045] In an embodiment of the present invention, the rooting position information of the pipe support in the cold box includes the rooting point coordinates of the support body on the attachment (i.e., coordinates of points A and A'), the model of the support body (which can be internally customized or defined according to recognized standards), the rooting point coordinates of the diagonal brace on the attachment (i.e., coordinates of point B), the model of the diagonal brace (which can be internally customized or defined according to recognized standards), and the block installation information (which may include whether the block is installed on one side, on both sides, or not installed, the installation height, the gap between the block and the pipe, etc.).

[0046] In an embodiment of the present invention, the material information required for processing the pipe support includes the processing dimension information of each structural component after the pipe support is disassembled (including the dimensions and materials of each rod in the main body of the support, the dimensions and materials of the diagonal brace, the relevant dimensions of the stop block, etc., parameters such as L1, L2, α, Δw1, Δw2, h, etc.).

[0047] The above information can be output as a structured pipe rack information table according to a preset format. It is generally preferred to output it in tabular form through an Excel file. If some information is missing, the cell can be set to empty or marked with a specific character.

[0048] To facilitate user operation, the aforementioned secondary development program can be designed with a visual user interface, allowing for intuitive understanding and operation. Users can directly input relevant parameters on the interface, and the program will automatically extract and display the precise position of the support. Therefore, in embodiments of the present invention, such as... Figure 10As shown, this paper presents a complete workflow for automatically generating the anchoring positions and material information of pipe supports within a cold box. First, utilizing the features of ATTA type elements and parametric element functions within AVEVA E3D software, meaningful point and shape sets are assigned to them, constructing a series of standard pipe support elements of different types. Parametric design variables are then used to adjust the positioning points and geometry. On the design side, the designer, based on relevant standards or experience, calls predefined standard pipe support elements to place the pipe support model and sets various designable variable parameters. The positions of the pipe support positioning points and anchoring points, as well as the geometry of the pipe support, are controlled through the pre-set point and shape set rules. On the AVEVA E3D software interface, the designer can clearly see the 3D model of the pipes and supports within the cold box and view the adjusted effects in real time, ultimately forming a 3D model of the pipe supports within the cold box. When automatic information aggregation and export are required, the user starts the secondary development program, which calls the interface provided by the AVEVA E3D software to collect and organize the pipe rack information, and finally generate a detailed and accurate pipe rack information table. This table covers the precise coordinates, installation angle, connection method, material type, cutting length, etc. of the support, providing accurate guidance for the construction of pipelines in the cold box.

[0049] Compared with traditional methods, this invention not only improves the accuracy of the pipe rack model and makes the design more intuitive, but also greatly reduces manual labor time and ensures the accuracy of information.

[0050] The embodiments described above are merely some preferred implementations of the present invention and are not intended to limit the invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, all technical solutions obtained through equivalent substitution or transformation fall within the protection scope of the present invention.
