Description

Technical Field

[0001] The present invention relates to the technical field of intelligent drawing modules for pipe supports, and particularly to a digital design method and system for pipe supports. Background Art

[0002] For a long time, when conducting pipe drawing design, the pipe supports are often hand-drawn in Auto CAD by redrawing the pipe supports in the national standard atlas; or the previously drawn pipe supports are copied and then modified. This results in low design quality and design efficiency.

[0003] Due to the large number of parts and troublesome drawing of pipe supports, which consume time, in some industries, the pipe design drawings even do not draw the pipe support drawings, but directly refer to the relevant national standard atlases.

[0004] Therefore, there is an urgent need for a digital design method for pipe supports to realize parametrically driving Auto CAD to automatically draw the large-scale drawings of pipe supports programmatically, replace manual hand-drawing, avoid the errors of manual drawing, and improve the design quality and design efficiency. Summary of the Invention

[0005] The purpose of the present invention is a digital design method and system for pipe supports, which avoid the large workload and drawing errors of manual drawing, and improve the design quality and design efficiency.

[0006] In order to achieve one of the above purposes, the present invention adopts the following technical solutions:

[0007] A digital design method for pipe supports includes the following steps:

[0008] S1: Establish database tables for each pipe support according to the classification of the national standard atlas, and construct an electronic database of the national standard atlas of pipe supports. Each of the pipe support database tables stores relevant attribute information of the pipe support. The attribute information at least includes nominal diameter, support height, support length, support structure size, support component material, support component specification, and support component weight;

[0009] S2: Establish data associations for each attribute information of the pipe support, and perform matching associations in the electronic database of the national standard atlas of pipe supports according to the association relationship to obtain corresponding pipe support information; including:

[0010] S201: Set the characteristic values of the database table;

[0011] S202: Establish an interactive interface for the pipe support design system in Auto CAD;

[0012] S203: Establish the characteristic relationships between the characteristic values of each pipe support;

[0013] S204: Match the data in the corresponding pipeline support database table according to the characteristic values;

[0014] S3: Automatically draw the pipeline supports based on the geometric position relationship algorithm according to the matched pipeline support information, including:

[0015] Obtain the attribute information of each pipeline support and the corresponding support data from the matched pipeline support database table,

[0016] Determine the reference points of the pipeline supports in Auto CAD, and use the geometric position relationship algorithm to automatically draw the corresponding drawings based on the support data.

[0017] Advantages of the present invention:

[0018] The method of the present invention constructs an electronic database of the national standard atlas of pipeline supports. In the interface of this Auto CAD secondary development program, the data related to the attribute information of each pipeline support is associated, and the corresponding algorithms are matched according to the data relationship information. By selecting or filling in the corresponding data in the interface and clicking to draw the drawings, the corresponding pipeline support drawings can be automatically drawn in Auto CAD within seconds, generating drawings and material tables, realizing parametric drawing, avoiding manual tracing, thus improving work efficiency, design depth, saving a large amount of repetitive drawing time, and also unifying the professional drawing standards. For construction units, it is also convenient to calculate the cost, prepare construction materials, and fabricate on-site pipeline supports. At the same time, it also avoids the occurrence of errors in manual drawing.

[0019] Compared with the prior art where general drawings do not draw or only indicate in text on which page of the atlas, the present invention increases the drawing depth and makes the design drawings more complete. It also realizes that the electronic version of the paper national standard atlas can be recognized and utilized by the program, so as to reproduce the large-scale drawings of the paper national standard atlas during the design process.

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Specific Embodiment 1:

[0061] Step S2: Establish data associations for each attribute information of the pipe support, and perform matching associations in the electronic database of the national standard atlas of pipe supports according to the association relationship to obtain pipe support information, including:

[0062] S201: Set the characteristic values of the database table

[0063] Set the characteristic values in each database table of the pipe support. The characteristic values include: pipe support detail drawing, nominal diameter, support height, and support length. Match the corresponding support data in the database according to the characteristic values.

[0064] S202: Establish an interactive interface for the pipe support design system in Auto CAD;

[0065] For the secondary development of Auto CAD, establish a pipe support design system. In the interactive interface of the pipe support design system, the user designs the content of the interactive interface for each characteristic value, that is, the digital design method of the pipe support of the present invention built in Auto CAD, and designs an interface for the user to select or input in the established pipe support design system.

[0066] Specifically, it includes:

[0067] Establish an interactive interface for the electronic database of the national standard atlas of supports, including database tables for each pipe support for selection. In this specific embodiment: establish an interactive interface for the electronic database of the national standard atlas of "Outdoor Heating Pipeline Supports 97R412". The electronic database of the national standard atlas of supports contains database tables for different supports, and the database tables contain Figure 2 the data shown.

[0068] Establish an interactive interface for the support type, including "fixed support" and "sliding support", for selecting any one of the two supports;

[0069] Establish an interactive interface for the support detail drawing, and associate the support detail drawing characteristics with the support type. For example, if the support type is a fixed support, the support detail drawing characteristics are T-shaped bracket fixed support, T-shaped bracket plus side plate fixed support, curved groove fixed support, and welded angle steel fixed support, for selecting one of them; for example, if the support type is a sliding support, the support detail drawing characteristics are arc plate sliding support, T-shaped bracket sliding support, T-shaped bracket plus side plate sliding support, and curved groove sliding support, for selecting one of them;

[0070] Create an interactive interface for the support length and input the support length; create an interactive interface for the support height and input the support height;

[0071] Create an interactive interface for the nominal diameter and input the nominal diameter; create an interactive interface for drawing the information of the pipe support, and the said interactive interface for drawing the information of the pipe support includes: the scaling ratio of the support, the character height ratio, and the drawing drawing. The said drawing drawing includes drawing the outline of the support and drawing the detailed drawing of the support. Any one of them can be selected, or both the outline of the support and the detailed drawing of the support can be selected at the same time.

[0072] It also includes: create an interactive interface for the insulation thickness. According to the requirement of whether the pipe support is insulated, if insulation needs to be considered, input the corresponding insulation thickness.

[0073] S203: Establish the characteristic relationships among the characteristic values of the pipe support;

[0074] Specifically include:

[0075] Establish the characteristic relationships among the detailed drawing of the pipe support, the support length, the support height, and the nominal diameter:

[0076] 1) For the arc plate sliding support, establish the following characteristic relationships:

[0077] Nominal diameter: DN20 - DN600; Support length: 200mm;

[0078] 2) For the tee sliding support, establish the following characteristic relationships:

[0079] Nominal diameter: DN20 - DN150; Support height: 50mm, 100mm; Support length: 150mm, 300mm;

[0080] 3) For the tee sliding support with side plates, establish the following characteristic relationships:

[0081] Nominal diameter: DN200 - DN300; Support height: 50mm, 100mm, 150mm; Support length: 200mm, 300mm;

[0082] 4) For the curved surface groove sliding support, establish the following characteristic relationships:

[0083] Nominal diameter: DN150 - DN600; Support height: 100mm, 150mm; Support length: 200mm, 300mm, 400mm;

[0084] 5) For the tee fixed support, establish the following characteristic relationships:

[0085] Nominal diameter: DN20 - DN150; Support height: 50mm, 100mm; Support length: 150mm, 300mm;

[0086] 6) Establish the following characteristic relationships for the T-shaped support with side fixed supports:

[0087] Nominal diameter: DN200 - DN300; Support height: 50mm, 100mm, 150mm; Support length: 200mm, 300mm;

[0088] 7) Establish the following characteristic relationships for the curved groove fixed support:

[0089] Nominal diameter: DN150 - DN600; Support height: 50mm, 100mm, 150mm; Support length: 200mm;

[0090] 8) Establish the following characteristic relationships for the welded angle steel fixed support:

[0091] Nominal diameter: DN20 - DN400; Support height: 0mm; Support length: 100mm, 200mm.

[0092] S204: Match the data in the corresponding pipeline support database table according to the characteristic values;

[0093] Specifically include:

[0094] According to the selection result of the pipeline support detail drawing, match the corresponding pipeline support data table in the electronic database of the national standard atlas of pipeline supports in S1; As Figure 2 shown in the database, it contains 8 pipeline support database tables, and each pipeline support database table corresponds one-to-one with the name of the pipeline support detail drawing.

[0095] In the matched pipeline support database table, according to the nominal diameter, support length, and support height, obtain the data parameters corresponding to the attribute information of the pipeline support. Taking the arc-shaped plate sliding support as an example, the following is a partial screenshot of the arc-shaped plate sliding support database table as shown in Table 1 below. Select the support data corresponding to the nominal diameter DN65 and support length 200mm in the characteristic values. Table 1

[0096]

[0097] Since the structural practices of each support are different, the types and contents of the matched data are also different. Through the above characteristic values of nominal diameter DN65 and support length 200mm, the arc length, arc height, arc material, arc specification, and arc weight of the arc-shaped plate of the pipeline support can be matched.

[0098] That is, the user selects the characteristic values of the pipeline support detail drawing, nominal diameter, support length, and support height in the interactive interface, and performs matching and association in the electronic database of the national standard atlas of pipeline supports in S1 to obtain the information of the pipeline support corresponding to the characteristic values.

[0099] It also includes establishing a database table for nominal diameter and pipe outer diameter, and obtaining the pipe outer diameter corresponding to the nominal diameter according to the matching relationship between the nominal diameter and the pipe outer diameter. As shown in Table 2 below, a partial screenshot of the database table for nominal diameter and pipe outer diameter makes the drawing more accurate.

[0100]

[0101] Step S3: Automatically draw pipe supports based on the geometric position relationship algorithm according to the matched pipe support information, including: obtaining various attribute information of the pipe supports and the corresponding support data information according to the matched pipe support database table.

[0102] Determine the reference point of the pipe support in the Auto CAD interface, and automatically draw the corresponding drawing using the geometric position relationship algorithm according to the support data information. The drawing includes the external shape drawing of the pipe support and the detailed drawing of the pipe support. Click to draw the external shape of the support and the detailed drawing of the support respectively to produce the external shape drawing of the pipe support and the detailed drawing of the pipe support including the material list.

[0103] That is, the present invention establishes a database file stored in the local computer according to the national standard atlas. The database contains multiple database tables with different names, and the names are exactly the same as the names of the pipe supports defined in the national standard atlas. Each database table contains parameters such as different nominal diameters, support lengths, support heights, support structure dimensions, materials, weights, etc. of the pipe supports.

[0104] After the user selects the specific name of the "detailed drawing of the support" in the interaction interface, it is automatically matched to the database table with the same name in the database. Then, according to the nominal diameter, support length, and support height selected by the user, other pipe production data information such as structure dimensions, materials, total quantity, etc. in the same-name database table is matched.

[0105] After the user clicks "draw the external shape of the support" or and "draw the detailed drawing of the support", it will prompt to select a point in the Auto CAD drawing area, and this point is the reference point for drawing the pipe support. Based on this reference point, according to the geometric position relationship drawing algorithm, various data matched from the database are used to drive Auto CAD to automatically complete the drawing.

[0106] Possibly, it also includes automatically generating a material list and automatically importing and writing the matched pipe support information into the table drawn by Auto CAD.

[0107] For example: Drawing of the arc plate sliding support

[0108] 1) According to the nominal diameter and the support length, query the data table of the arc plate sliding support, and the arc length of the arc plate, the height of the arc plate, the material, the specification of the arc plate, and the weight data (as shown in Table 3 below) can be obtained. According to the established database table of the pipe nominal diameter and the pipe outer diameter, the pipe outer diameter corresponding to the nominal diameter can be obtained according to the pipe nominal diameter. Table 3:

[0109]

[0110] 2) According to the nominal diameter and the support length, the corresponding H is the height of the arc plate, Dw is the pipe outer diameter corresponding to the nominal diameter, and L is the arc length of the arc plate.

[0111] 3) Refer to Figure 4 As shown, in Auto CAD, left-click on a point as the starting point A for drawing the support. This point is the Figure 4 reference point A of the arc plate sliding support shown, and the coordinates of the reference point A are expressed as A(x, y, z).

[0112] 4) Draw the pipe 1 with an outer diameter of Dw according to the geometric position relationship algorithm. This geometric position relationship is the geometric position relationship between the center points of the existing pipes and the reference point. According to the reference point A, the height H of the arc plate, and the pipe outer diameter Dw, calculate the center point O(x, y + H + Dw / 2, z) of the pipe according to the following coordinate point algorithm, and use O as the center to drive Auto CAD to draw a circle with a radius of Dw / 2. This circle represents the pipe 1.

[0113] 5) Draw the arc plate 2 according to the geometric position relationship algorithm. This geometric position relationship is the geometric position relationship between the arc plate and the center of the circle. The height H, the outer diameter Dw, and the arc length L of the arc plate are known data, and can be calculated according to the formula ∠V is half of the radian corresponding to the arc length L.

[0114] With O as the center, draw arcs with radii of Dw / 2 and Dw / 2 + H respectively, and drive Auto CAD to draw arcs with a radian of 2∠V. The starting radian of the arcs is 3π / 2 - ∠V, and the ending radian is 3π / 2 + ∠V. Then connect the starting endpoints P1, P2 and the ending endpoints P3, P4 of the two arcs. The arc plate 2 is composed of the straight lines P1P2, P3P4 and the arcs P2P4, P1P3.

[0115] 6) The above is the method for drawing the external shape diagram (front view) of the pipe support. In the Auto CAD development environment of C#, the above formulas and geometric position relationship algorithms are incorporated into the code, and then compiled to generate an assembly that can drive Auto CAD to draw automatically. The code drives Auto CAD in the program to achieve this.

[0116] 7) Refer to Figure 5 、Figure 6 , Figure 7 As shown in Figure 7 , based on the drawing method of the external shape diagram (front view) of the pipe support, the detailed drawing of the pipe support can be further drawn. The detailed drawing of the pipe support includes: the external shape diagram (front view) of the pipe support, the side view of the pipe support, the corresponding schematic diagram of the bottom support structure, and the bill of materials. The algorithm is as follows:

[0117] 7.1) Automatically draw the external shape diagram (front view) of the pipe support according to steps 1) to 6).

[0118] 7.2) At the bottom of the external shape diagram (front view) of the pipe support drawn in 7.1), draw two rectangles. The rectangles are used to represent the bottom support structure. Among them, the rectangular support structure in direct contact with the pipe support is small, and the size of the bottommost support structure is large.

[0119] As shown in Figure 5 represents the bottom support structure. Based on the reference point, draw the first rectangular bottom support with a length of Q1 and a width of Z1. The values of the length and width of the first rectangular bottom support are as follows:

[0120] Z1 = 3, Q1 = 0.8*Dw.

[0121] Below the first rectangular bottom support, there is also a schematic diagram of the second rectangular support structure. The left and right sides of the support structure are cutting lines. The schematic length of the second rectangular support structure is Q2 and the width is Z2. The values are as follows:

[0122] Z2 = 10, Q2 = 1.6*Dw.

[0123] 7.3) Based on the external shape diagram (front view) of the pipe support drawn in 7.1), draw the side view of the pipe support on the right according to the geometric projection relationship.

[0124] As shown in Figure 6 the side view of the pipe and the support is drawn based on the projection relationship.

[0125] Pipe side view: Dw is the outer diameter of the pipe, and L1 is the schematic length of the pipe. In this specific embodiment: take L1 = 500.

[0126] Side view of the arc plate: L2 is the length of the support, H4 is the distance between the projection point of point P3 on the OA axis and the reference point A, and H5 is the distance between the projection point of point P4 on the OA axis and the reference point A.

[0127] Bottom support side view: A rectangle with Z1 = 3 and X1 = 20.

[0128] Side view of the lower support structure of the bottom support: A rectangle with Z2 = 10 and X2 = 220.

[0129] The implementation of the above drawing method is still based on the reference points and the dimensions of each part for drawing. There will be two intersection points between the side view of the pipe support and the lower edge of the pipe. The lower edge of the pipe between the intersection points drives Auto CAD to delete it.

[0130] 7.4) As Figure 7 shown, write the arc length, height, material, specification, and weight data of the arc-shaped plate obtained by matching in 1) into the table drawn in Auto CAD, which is the material table.

[0131] For example: Drawing method of T-shaped support sliding support

[0132] 1) According to the nominal diameter, support length, and support height, query the data table of the T-shaped support sliding support to obtain data such as material, top plate specification, top plate height, top plate length, top plate thickness, top plate mass, bottom plate specification, bottom plate width, bottom plate length, bottom plate thickness, mass, and total mass (as shown in Table 4 below). Through the pipeline outer diameter database corresponding to the pipeline nominal diameter, obtain the pipeline outer diameter corresponding to the pipeline nominal diameter. Table 4

[0133]

[0134] 2) It is obtained that H2 is the height of the top plate of the T-shaped support sliding support (i.e., the support height), C is the top plate thickness, B is the bottom plate width, H1 is the bottom plate thickness, Dw is the pipeline outer diameter corresponding to the nominal diameter, and T is the insulation layer thickness.

[0135] 3) As shown in Figure 8 , in Auto CAD, left-click on a point as the reference point A for drawing the support, and the coordinates of this point A are A(x, y, z).

[0136] 4) Draw pipeline 1 with an outer diameter of Dw according to the geometric position relationship algorithm. Based on the reference point A, calculate the center point O(x, y + H1 + H2 + Dw / 2, z) of the pipeline according to the following coordinate point algorithm, and draw a circle with a radius of Dw / 2 with point O as the center. This circle represents the pipeline.

[0137] 5) Draw the bottom plate 3 of the T-shaped support sliding support according to the geometric position relationship algorithm. Taking point A as the reference point, B and H1 as the width and height of the bottom plate, calculate the four vertices of the rectangular bottom plate according to the following coordinate point algorithm. The lower left point P5(x - B / 2, y, z); the upper left point P6(x - B / 2, y + H1, z); the lower right point P7(x + B / 2, y, z); the upper right point P8(x + B / 2, y + H1, z). Connect these four vertices to draw the rectangular support bottom plate 3.

[0138] 6) Draw the top plate 4 of the T-shaped bracket sliding support according to the geometric position relationship algorithm. Taking point A as the reference point, calculate the four vertices of the rectangular top plate according to the following coordinate point algorithm: D1(x - C / 2, y + H1, z), D2(x - C / 2, y + H1 + H2, z), D3(x + C / 2, y + H1 + H2, z), D4(x + C / 2, y + H1, z). Connect these four vertices to draw the rectangular support top plate 4.

[0139] 7) Draw the pipe insulation layer 5 according to the geometric position relationship algorithm. When the insulation layer thickness T = 0, do not draw the pipe insulation layer. When the insulation layer thickness T > 0, draw a circle with point O as the center and Dw + 2*T as the diameter. This circle represents the pipe insulation layer 5.

[0140] 8) The above is the algorithm for drawing the external shape diagram (front view) of the pipe support, which is driven by the code in the program to implement Auto CAD.

[0141] See Figure 9 、 Figure 10 、 Figure 11 As shown in: 9) Based on the drawing algorithm of the external shape diagram (front view) of the pipe support, the detailed drawing of the pipe support can be further drawn. The detailed drawing of the pipe support includes: the external shape diagram (front view) of the pipe support, the side view of the pipe support, the corresponding bottom support structure schematic diagram, and the bill of materials. The algorithm is as follows:

[0142] 9.1) Automatically draw the external shape diagram (front view) of the pipe support according to steps 1) to 8).

[0143] 9.2) At the bottom of the external shape diagram (front view) of the pipe support drawn in 9.1), draw two rectangles. The rectangles are used to represent the bottom support structure. Among them, the rectangular support structure in direct contact with the pipe support is small, and the size of the bottommost support structure is large.

[0144] As Figure 9 shows the bottom support structure. Based on the reference point, draw the first rectangular bottom support with length Q1 and width Z1. The values of the length and width of the first rectangular bottom support are as follows: Z1 = 3, Q1 = 1.5*B.

[0145] Below the first rectangular bottom support, there is also a schematic diagram of the second rectangular bottom support structure. The left and right sides of the second rectangular bottom support structure are cutting lines. The schematic length of the second rectangular bottom support structure is Q2 and the width is Z2. The values are as follows:

[0146] Z2 = 10, Q2 = 1.6*Dw.

[0147] 9.3) On the basis of the external shape diagram (front view) of the pipe support drawn in 9.1), draw the side view of the pipe support on the right according to the geometric projection relationship.

[0148] As Figure 10 shown in the side view of the pipeline and the support, which is drawn based on the projection relationship.

[0149] Side view of the pipeline: Dw is the outer diameter of the pipeline, L1 is the schematic length of the pipeline, and L1 = 2 * L2 is taken.

[0150] Side view of the T-shaped bracket sliding support: L2 is the length of the support, H2 is the height of the support, and H1 is the thickness of the bottom plate.

[0155] For example: Drawing method of the T-shaped bracket with side plate sliding support

[0156] 1) According to the nominal diameter, support length, and support height, query the data table of the T-shaped bracket with side plate sliding support to obtain the data of material, top plate specification, top plate height, top plate length, top plate thickness, top plate mass, bottom plate specification, bottom plate width, bottom plate length, bottom plate thickness, bottom plate mass, side plate specification, side plate single width, side plate mass, side plate thickness, side plate mass, distance between the drainage hole and the center line, and total mass (as shown in Table 5-1 and Table 5-2 below).

[0161] 3) The T-shaped bracket plus side plate sliding support is to add side plates on the basis of the T-shaped bracket sliding support. Therefore, following the drawing algorithm of the T-shaped bracket sliding support, first draw the T-shaped bracket sliding support.

[0162] 4) Draw the top surface of the side plate according to the geometric position relationship algorithm. ∠V is the semi-angle radian, and K is the width of a single side plate. Calculate ∠V according to the following algorithm: ∠V = arcsin(2*K / Dw). With O as the center and 2∠V as the radian, draw an arc with the starting point radian of 3π / 2 - ∠V and the ending point radian of 3π / 2 + ∠V. This arc is the arc curve of the top surface of the side plate.

[0163] 5) Draw the left side of the left side plate according to the geometric position relationship algorithm. According to the following coordinate point algorithm, calculate the coordinates of point M1 on the left side plate: P1(x - C / 2 - K, y + H1, z). Starting from this point, draw a ray upwards, and find the first intersection point M2 of the ray and the circle representing the pipeline. Connect M1 and M2, and this straight line represents the left side of the left side plate 6.

[0164] 6) Draw the right side of the right side plate according to the geometric position relationship algorithm. Taking the line segment OA as the axis of symmetry, the right side of the right side plate 7 is obtained by symmetry with the left side of the left side plate 6 obtained in 5).

[0165] 7) The above is the drawing of the external shape diagram (front view) of the pipeline support, which is realized by driving Auto CAD in the program with code.

[0166] See Figure 13 、 Figure 14 、 Figure 15 As shown, 8) On the basis of the drawing algorithm of the external shape diagram (front view) of the pipeline support, the detailed drawing of the pipeline support can be further drawn. The detailed drawing of the pipeline support includes: the external shape diagram (front view) of the pipeline support, the side view of the pipeline support, the corresponding bottom support structure schematic diagram, and the bill of materials. The method is as follows:

[0168] 8.2) Draw two rectangles at the bottom of the external shape diagram (front view) of the pipeline support drawn in 8.1). The rectangles are used to represent the bottom support structure, where the rectangular support structure in direct contact with the pipeline support is small, and the size of the bottommost support structure is large.

[0169] As Figure 13 represents the bottom support structure. Based on the reference point, draw the first rectangular bottom support with length Q1 and width Z1. The values of the length and width of the first rectangular bottom support are as follows:

[0170] Z1 = 3, Q1 = 1.5*B.

[0171] Below the support at the bottom of the first rectangle, there is also a schematic diagram of the second rectangle bottom support structure. The left and right sides of the second rectangle bottom support structure are cutting lines. The schematic length of the second rectangle bottom support structure is Q2 and the width is Z2, and the values are as follows:

[0172] Z2 = 10, Q2 = 1.6 * Dw.

[0173] 8.3) On the basis of the external shape drawing (front view) of the pipe support drawn in 8.1), draw the side view of the pipe support on the right according to the geometric projection relationship.

[0174] As Figure 14 shows the side view of the pipe and the support, drawn based on the projection relationship.

[0175] Side view of the pipe: Dw is the outer diameter of the pipe, and L1 is the schematic length of the pipe. Take L1 = 2 * L2.

[0176] Side view of the T-shaped bracket sliding support: L2 is the length of the support, H2 is the height of the support, and H1 is the thickness of the bottom plate.

[0177] Side view of the side plate: G is the height of the side plate (the length of the line segment M1M2), and J is the thickness of the side plate.

[0178] Side view of the bottom support: A rectangle with Z1 = 3 and X1 = 20.

[0179] Side view of the lower support structure of the bottom support: A rectangle with Z2 = 10 and X2 = 220. The realization of the above drawing method is still based on the reference points and the dimensions of each part for drawing.

Obtain the corresponding outer diameter of the pipe by matching the pipe nominal diameter, Table 6-1

[0183]

[0185]

[0186] 2) Refer to Figure 16 As shown, B1 is the width of the rib plate, H3 is the height of the rib plate, H4 is the support height of the curved surface groove sliding support, B2 is the width of the curved surface groove, N is the thickness of the curved surface groove, Dw is the outer diameter of the pipe corresponding to the nominal diameter, T is the thickness of the insulation layer, H is the height of the arc plate, and L is the arc length of the arc plate.

[0187] 3) In Auto CAD, left-click on a point to select it as the reference point A for drawing the support. The coordinates of the reference point A are represented as A(x, y, z). Point O is the center of the pipe. According to the following coordinate point algorithm, the coordinates of O are calculated as O(x, y + H + Dw / 2, z).

[0188] 4) Draw the pipe, arc plate, and insulation layer according to the geometric position relationship algorithm. With point O as the center, according to the algorithm in 3.1, the pipe and arc plate can be drawn. With point O as the center and Dw + 2*T as the diameter, draw a circle to obtain the insulation layer.

[0189] 5) Draw the rib plate according to the geometric position relationship algorithm. With point A as the reference point, according to the following coordinate point algorithm, the four vertices of the rib plate are calculated as L1(x - B1 / 2, y + 20, z), L2(x - B1 / 2, y + 20 + H2, z), L3(x + B1 / 2, y + 20, z), and L4(x + B1 / 2, y + 20 + H2, z). Connect the above four points to draw the rectangular rib plate 8 figure.

[0190] 6) Draw the curved surface groove according to the geometric position relationship algorithm. First, draw the outer edge rectangle of the curved surface groove. According to the following coordinate point algorithm, the coordinates of each point are calculated as G1(x - B2 / 2, y, z) and G3(x + B2 / 2, y, z). Starting from points G1 and G3, draw rays upward to intersect the arc plate to obtain G2 and G4. Connect G2, G1, G3, and G4 in sequence to obtain the outer edge line of the rectangular curved surface groove. Then, chamfer the line segments G2G1 and G1G3 with a radius R = 10, and chamfer G1G3 and G3G4 with a radius R = 10 to obtain the actual outer edge line of the curved surface groove. Similarly, offset the outer edge line of the curved surface groove inward by a thickness K to draw the inner edge line of the curved surface groove 9.

[0191] 7) The above is the algorithm for drawing the external view (front view) of the pipe support, which is implemented by the code driving Auto CAD in the program.

[0192] Refer toFigure 17 , Figure 18 , Figure 19 As shown in Figure 19 , 8) Based on the drawing algorithm of the external shape drawing (front view) of the pipe support, the detailed drawing of the pipe support can be further drawn. The detailed drawing of the pipe support includes: the external shape drawing (front view) of the pipe support, the side view of the pipe support, the corresponding schematic diagram of the bottom support structure, and the bill of materials. The algorithm is as follows:

[0194] 8.2) At the bottom of the external shape drawing (front view) of the pipe support drawn in 8.1), draw two rectangles. The rectangles are used to represent the bottom support structure. Among them, the rectangular support structure in direct contact with the pipe support is small, and the size of the bottommost support structure is large.

[0195] As Figure 17 shown, it represents the bottom support structure. Based on the reference point, draw the first rectangular bottom support with a length of Q1 and a width of Z1. The values of the length and width of the first rectangular bottom support are as follows: Z1 = 3, Q1 = 1.5 * B.

[0196] Below the first rectangular bottom support, there is also a schematic diagram of the second rectangular bottom support structure. The left and right sides of the second rectangular bottom support structure are cutting lines. The length of the support structure schematic is Q2 and the width is Z2. The values are as follows: Z2 = 10, Q2 = 1.6 * Dw.

[0197] 8.3) On the basis of the external shape drawing (front view) of the pipe support drawn in 8.1), draw the side view of the pipe support on the right according to the geometric projection relationship.

[0198] As Figure 18 shown, it represents the side view of the pipe and the support, which is drawn based on the projection relationship.

[0199] Pipe side view: Dw is the outer diameter of the pipe, L1 is the schematic length of the pipe, and take L1 = 2 * L2.

[0206] For example: Drawing method of T-shaped bracket fixed support

[0207] See Figure 20 shown, the drawing algorithm of the external shape drawing (front view) of the pipe support of the fixed support and the detailed drawing of the pipe support is the same as that of the T-shaped bracket sliding support, so this specific embodiment is omitted here.

[0208] In the material table, mark "Weld the support to the support plate to make a fixed support". For example: Drawing algorithm of T-shaped bracket plus side plate fixed support

[0209] See Figure 21 shown, the drawing algorithm of the external shape drawing (front view) of the pipe support of the fixed support and the detailed drawing of the pipe support is the same as that of the T-shaped bracket plus side plate sliding support, so this specific embodiment is omitted here.

[0210] In the material table, mark "Weld the support to the support plate to make a fixed support". For example: Drawing algorithm of curved surface groove fixed support

[0211] See Figure 22 shown, the drawing algorithm of the external shape drawing (front view) of the pipe support of the fixed support and the detailed drawing of the pipe support is the same as that of the curved surface groove sliding support, so this specific embodiment is omitted here.

[0212] In the material table, mark "Weld the support to the support plate to make a fixed support". For example: Drawing method of welded angle steel fixed support

[0217] 4) Draw the pipe 1 according to the geometric position relationship algorithm. According to the coordinate point algorithm, calculate the center O of the pipe, O(x, y + Dw / 2, z). Draw a circle with a diameter of Dw with O as the center, and this circle is the pipe.

[0218] 5) Draw the left and right angle steels 10 according to the geometric position relationship algorithm. F is the horizontal length of the angle steel, and H5 is the vertical height of the angle steel. According to the coordinate point algorithm, calculate the vertexes J1(x - B / 2, y, z) and J2(x + B / 2, y, z) of the angle steel. Respectively, with points J1 and J2, draw the outline of the angle steel 10 according to the height H5, length F of the angle steel and the thickness E of the angle steel. Among them, the three chamfer radii R1 of the angle steel 10 are selected according to the thickness of the angle steel.

[0219] 6) The above is the algorithm for drawing the external view (front view) of the pipe support, which is implemented by driving Auto CAD in the program with code.

[0220] See Figure Figure 24 、 Figure 25 、 Figure 26 As shown, 7) On the basis of the drawing algorithm of the external view (front view) of the pipe support, the detailed drawing of the pipe support can be further drawn. The detailed drawing of the pipe support includes: the external view (front view) of the pipe support, the side view of the pipe support, the corresponding bottom support structure schematic diagram and the bill of materials. The algorithm is as follows:

[0221] 7.1) Automatically draw the external view (front view) of the pipe support according to steps 1) to 6).

[0222] 7.2) Draw a rectangle at the bottom of the external view (front view) of the pipe support drawn in 7.1), and the rectangle is used to represent the bottom support structure.

[0223] As Figure 24 represents the bottom support structure. It is drawn based on the reference point, and the left and right sides of the support structure are cut lines. The schematic length of the support structure is Q2 and the width is Z2, and the values are as follows:

[0224] Z2 = 10, Q2 = 1.6 * Dw.

[0225] 7.3) On the basis of the external view (front view) of the pipe support drawn in 7.1), draw the side view of the pipe support on the right according to the geometric projection relationship.

[0226] As Figure 25 Shown is a side view of the pipe and the support, drawn based on the projection relationship.

[0227] Side view of the pipe: Dw is the outer diameter of the pipe, L1 is the schematic length of the pipe, and L1 = 2 * L2 is taken.

[0229] Side view of the lower support structure: A rectangle with Z2 = 10 and X2 = 220.

[0230] The implementation of the above drawing method is still based on the reference points and the dimensions of each part for drawing.

[0231] As Figure 26 Shown in the figure, 7.4) Write the support length, net distance of the angle steel, vertical height of the angle steel, horizontal length of the angle steel, thickness of the angle steel, specification of the angle steel, single weight of the angle steel, and total mass of the support obtained by matching in 1) into the table drawn by Auto CAD, which is the material list.

[0232] The above is the drawing algorithm for the front view of the pipe. In the drawing of the pipe support detail drawing, the side view of the pipe is also drawn, and the algorithm for the side view of the pipe is also drawn according to the support structure dimension data.

[0233] Possibly, the pipe support drawing can be drawn according to different scales. The above can be drawn at a scale of 1:1 according to the actual dimensions in the database or other scales, and the user can select the support scaling ratio and the character height ratio in the interface. When the support scaling ratio is input, Auto CAD automatically draws the drawing according to the scaling ratio, and at the same time, when the character height ratio is input, Auto CAD automatically adjusts the character height according to the ratio during text annotation.
