Description

Technical Field

[0001] The invention belongs to the technical field of mechanical and electrical installation in construction engineering, and relates to a method for dividing prefabricated processing components for assembly construction of air-conditioning water pipelines in an assembled machine room. Background Art

[0002] The electromechanical assembly construction process is a major challenge for the transformation of construction companies and an inevitable development trend of modern production. How to perfectly transform the traditional electromechanical pipeline on-site welding construction process into a construction method for prefabricated component factory processing and on-site assembly of prefabricated components has become a current need. The traditional construction process only needs to measure the total length of the pipeline raw materials and cut and weld on site. The assembly construction requires the entire machine room pipeline to be divided into components. If the components are too fragmented, they cannot play the role of factory batch production. If the components are too large, it will be difficult to transport them from the factory to the construction site by truck. The obstacles on the on-site hoisting port and transportation route are also not allowed. In addition, the accuracy of the current factory processing equipment, the negative deviation of the material components, welding deformation and other factors may lead to errors between the components and the design dimensions. If the errors are not eliminated or controlled, it is very likely to cause mismatches in the on-site assembly or excessive assembly errors, leading to quality risks. Therefore, choosing reasonable division rules to ensure transportation, assembly operability, error control, standardization and batch production have become the current difficulties of the assembled machine room. Summary of the invention

[0003] In order to overcome the above problems, the present invention provides a method for dividing assembly parts applied to water pipes of air conditioners in assembled computer rooms, so that the pipe segmentation has a basis and rules to follow.

[0004] The present invention adopts the following technical solutions:

[0005] A method for dividing assembly parts applied to assembled room air conditioning water pipes is characterized in that: under the conditions of meeting the operating conditions of assembled prefabricated processing machinery and equipment, the truck transportation conditions, on-site transfer conditions and the convenience of assembly component operation are considered, and through comprehensive correlation analysis, each assembly part is divided into several types of assembly parts, namely, straight pipe section, straight pipe section with elbow, tee, B-shaped bend and differential section; the above-mentioned types of assembly parts respectively comply with the straight pipe section segmentation rules, the straight pipe section with elbow segmentation rules, the tee segmentation rules and the B-shaped bend segmentation rules. Based on the three-dimensional model of the assembled room air conditioning water pipe, the various types of assembly parts are divided according to the priority of the sequence, and the specific steps are as follows:

[0006] (1) Select the starting point of the segment, starting from the pipe end at the entrance of the machine room;

[0007] (2) Take X meters as a section and follow the straight pipe section division rules;

[0008] (3) If a pipe fitting is encountered and the segment length does not meet X meters, determine whether it is an elbow. If so, execute the straight pipe segment with elbow segmentation rules, add flanges to the ports, generate straight pipe segment with elbow assembly parts, and enter the straight pipe segmentation again after completion; if the pipe fitting is not an elbow, proceed to the next step of judgment;

[0009] (4) If the pipe fitting encountered is a tee, the tee segmentation rule is executed, a flange is added to the port, and a tee assembly is generated. After completion, the straight pipe segmentation is performed again; in addition, the tee branch pipe end is used as the starting point and segmentation is performed from step (2); if the pipe fitting is not a tee, the next step of judgment is performed;

[0010] (5) If the pipe fitting encountered is a U-bend, the U-bend segmentation rule is executed, a flange is added to the port, and a U-bend assembly is generated. After completion, the straight pipe segmentation is entered again;

[0011] (6) If the straight pipe segment meets the end of the pipeline or the equipment valve, the segmentation of the assembly parts is terminated;

[0012] (7) If the straight pipe section with elbow assembly is the last component, it is defined as the differential section, and no flange is added; the component between the equipment interface and the valve is also defined as the differential section;

[0013] (8) Overall determine whether the added flanges meet the requirements of alignment in the same position or alignment in odd or even positions. The flange ports of the same type of branch pipes should maintain the same elevation and position. If not, adjust the length of the pipe section and the position of the flange.

[0014] (9) Overall determine whether the principle of the flange not colliding with the bracket is met. If not, adjust the length of the pipe section and the position of the flange. At this point, the division of the assembly components is completed.

[0015] The tees include one main branch tee, a main branch with two same-direction tees, a main branch with two different-direction tees and a main branch with three same-direction tees.

[0016] The U-shaped bend includes a transverse U-shaped bend and a transverse and longitudinal U-shaped bend.

[0017] The straight pipe segmentation rules are specifically as follows:

[0018] The length of the straight pipe section X = [a1, L], a1 is the minimum operating value corresponding to the pipe diameter D, when 100mm≤D<400mm, a1 is 250mm; when 400mm≤D<500mm, a1 is 450mm; when 500mm≤D≤600mm, a1 is 500mm; L is determined according to the standard size of the pipeline, which is 6000mm, 9000mm or 12000mm. The maximum value in the straight pipe section segmentation rule takes into account the common size of pipes on the market, and the minimum value takes into account the minimum space required for the welding flange during the pipe and flange welding operation.

[0019] The segmentation rules of the pipe sections with elbows are specifically as follows:

[0020] The length of the straight pipe section with elbow is X≤L-a2, where a2 is the minimum operating value corresponding to the pipe diameter D. When 100mm≤D<300mm, a2 is 200mm; when 300mm≤D≤600mm, a2 is 500mm; the distance between the straight pipe section and the elbow is Y≤B-a2, where B is the limited value for transport and packing. When 100mm≤D<300mm, a2 is 400mm; when 300mm≤D≤600mm, a2 is 900mm; The short-circuit length of the flange with elbow is Y1=[b1,BR], where b1 is the minimum operating value corresponding to the pipe diameter D. When 100mm≤D<300mm, b1 is 200mm; when 300mm≤D≤600mm, b1 is 250mm; R is the radius of curvature of the elbow, which is 1.5D or 1.0D; L is determined according to the standard size of the pipeline, which is 6000mm, 9000mm or 12000mm; B is 2200mm according to the conventional size of the truck compartment. The segmentation rule of the straight pipe section with elbows is to consider that the length and width of the pipe section need to be less than or equal to the set transportation length and transportation width. The length and width are calculated based on the outermost edge of the flange, and the thickness of the gasket is not calculated. The length is combined with the common size of the pipeline and the common truck packing length, and the width is combined with the common truck packing width and the common allowable size for transportation convenience.

[0021] The three-way segmentation rules are specifically as follows:

[0022] When there is one tee in the main pipe branch, the length X of the tee pipe section satisfies X ≤ L, the distance value X1 from the axis of the branch pipe to the pipe end satisfies X1 ≥ a3 and X1 < L, where a3 is the minimum operating value corresponding to the pipe diameter D. When 100mm ≤ D ≤ 600mm, a3 is taken as 250mm; the distance value Y from the end of the branch pipe to the axis of the main pipe satisfies Y ≤ B - b2, where b2 is the minimum operating value corresponding to the pipe diameter D. When 100mm ≤ D < 500mm, b2 is taken as 200mm; when 500mm ≤ D ≤ 600mm, b2 is taken as 300mm; the vertical height difference value Z between the axis of the branch pipe and the axis of the main pipe satisfies Z ≤ h1. When 100mm ≤ D < 400mm, h1 is taken as 1500mm; when 400mm ≤ D ≤ 600mm, h1 is taken as 1000mm; L is determined according to the standard pipe size and is 6000mm, 9000mm or 12000mm; B limits the transportation width according to the conventional size of the freight car compartment and is 2200mm.

[0023] When there are two same-direction TY tees in the main pipe branch, the length X of the tee pipe section satisfies X ≤ L, the distance value X1 from the axis of the branch pipe to the pipe end is X1 = [a4, L3], where a4 is the minimum limit value of the tee branch end corresponding to the pipe diameter D. When 100mm ≤ D ≤ 600mm, a4 is taken as 300mm. L3 is the maximum limit value of the tee branch end corresponding to the pipe diameter D. When 100mm ≤ D < 450mm, L3 is taken as 1500mm, when 450mm ≤ D ≤ 600mm, L3 is taken as 1000mm; the distance value X2 between the axes of the two branch pipes satisfies X2 ≤ c1, where c1 is the limit value of the branch pipe spacing corresponding to the pipe diameter D. When 100mm ≤ D ≤ 600mm, c1 is taken as 4000mm; the vertical height difference value Z between the end of the branch pipe and the axis of the main pipe satisfies Z ≤ h2. When 100mm ≤ D < 400mm, h2 is taken as 1500mm; when 400mm ≤ D ≤ 600mm, h2 is taken as 1000mm; L is determined according to the standard pipe size and is 6000mm, 9000mm or 12000mm.

[0024] When the main pipe branches into two tees in different directions, the length of the tee section is X≤L, and the distance between the branch pipe axis and the pipe end is X1=[a5,c2], where a5 is the minimum limit of the branch pipe spacing corresponding to the pipe diameter D. When 100mm≤D≤600mm, a5 is 300mm; c2 is the maximum limit of the branch pipe spacing corresponding to the pipe diameter D. When 100mm≤D<400mm, c2 is 1500mm, and when 400mm≤D≤600mm, c2 is 1000mm; the distance between the two branch pipe axes is X2≤L4, where L4 is the maximum limit of the tee branch spacing corresponding to the pipe diameter D. When 100mm≤D≤600mm, L4 is 4000mm; The length of the upward branch pipe is Y1≤L5, L5 is the maximum limit of the upward branch pipe of the tee corresponding to the pipe diameter D, when 100mm≤D≤600mm, L5 is 500mm, the length of the horizontal branch pipe is Y2≤L6, L6 is the maximum limit of the horizontal branch pipe of the tee corresponding to the pipe diameter D, when 100mm≤D≤600mm, L6 is 1000mm; the vertical height difference between the branch pipe end and the main pipe axis Z≤h3, when 100mm≤D<400mm, h3 is 1500mm; when 400mm≤D≤600mm, h3 is 1000mm, L is determined according to the standard size of the pipeline, which is 6000mm, 9000mm or 12000mm;

[0025] When the main pipe branches out three tees in the same direction, the length of the tee section is X≤L, and the distance between the branch pipe axis and the pipe end is X1=[a6,c3], where a6 is the minimum limit value of the branch pipe spacing corresponding to the pipe diameter D. When 100mm≤D≤600mm, a6 is 300mm; c3 is the maximum limit value of the branch pipe spacing corresponding to the pipe diameter D. When 100mm≤D<400mm, c3 is 1500mm, and when 400mm≤D≤600mm, c3 is 1000mm; the distance between the two branch pipe axes is X2≤L7, L7 is the maximum limit value of the branch pipe spacing corresponding to the pipe diameter D. When 100mm≤D<400mm, L7 is 2000mm; when 400mm≤D≤600mm, L7 is 2500mm; the vertical height difference between the branch pipe end and the main pipe axis Z≤h4, when 100mm≤D≤<400mm, h4 is 1500mm; when 400mm≤D≤600mm, h4 is 1000mm. L is determined according to the standard size of the pipeline, which is 6000mm, 9000mm or 12000mm.

[0026] The specific segmentation rules of the B-shaped curve are as follows:

[0027] For the transverse B-shaped bend in pipe diameter D, when 100mm≤D<400mm, the B-shaped bend adopts an angle less than 90 degrees, the total length X≤L, the length of the straight pipe section X1 / X2≤L8, L8 is the maximum limit of the small angle of the transverse B-shaped bend, which is 2500mm; when 400mm≤D≤600mm, the length of the B-shaped bend X≤B, the B-shaped bend adopts a 90-degree angle, the distance value of the end face of the B-shaped bend from the vertical centerline X1 / X2≤L9, L9 is the maximum limit of the 90-degree transverse B-shaped bend, which is 1000mm, and L is determined according to the standard size of the pipeline, which is 6000mm, 9000mm or 12000mm; B is the transportation width limited by the conventional size of the truck compartment, which is 2200mm;

[0028] The distance X / Y between the end face of the transverse and longitudinal B-shaped bend and the axis center of the corner is ≤L10, where L10 is the maximum limit of the small angle of the transverse B-shaped bend. The transverse and longitudinal B-shaped bend pipe diameter D, when 100mm≤D<350mm, L10 is 2000mm, and when 350mm≤D≤400mm, L10 is 1900mm; the longitudinal height difference Z of the transverse and longitudinal B-shaped bend is ≤h5, when 100mm≤D≤400mm, h5 is 1000mm, and when the pipe diameter D is above 400mm, it cannot be classified as a B-shaped bend; L is determined according to the standard size of the pipeline, which is 6000mm, 9000mm or 12000mm.

[0029] The segmentation rules for the I-shaped bend take into account the errors caused by changes in the lateral or longitudinal elevation of the I-shaped bend on the one hand, and the inconvenience of the I-shaped bend in assembly transportation on the other hand, thereby determining the limiting data.

[0030] The division of assembly parts in the present invention takes into account that the length and width of the pipe section need to be less than or equal to the set transportation length and transportation width. The length and width are calculated based on the outermost edge of the flange, and the thickness of the gasket is not calculated. The length is combined with the common size of the pipeline and the common truck packing length, and the width is combined with the common truck packing width and the common allowable size for transportation convenience.

[0031] The adjustment section in step (7) is set as the machine room sorting error elimination to ensure that the error accumulation affected by material product size, prefabrication production accuracy, assembly control and other aspects is eliminated, thereby ensuring the sorting assembly accuracy.

[0032] The flange adjustment in steps (8) and (9) is to ensure the aesthetics of the overall assembly effect.

[0033] The present invention solves the problems of unsatisfactory division of prefabricated components in assembled computer rooms, resulting in unqualified component processing quality, inconvenient transportation and assembly, and frequent assembly errors, improves the assembly accuracy and quality of air-conditioning water pipes in assembled computer rooms, and improves the efficiency of assembly construction.

[0046] The present invention will be further described below in conjunction with the accompanying drawings.

[0047] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the present invention is a method for dividing assembly parts applied to assembled room air-conditioning water pipes, characterized in that: under the conditions of meeting the operating conditions of assembled prefabricated processing machinery and equipment, considering the truck transportation conditions, on-site transfer conditions and the convenience of assembly component operation, through comprehensive correlation analysis, each assembly part is divided into several types of assembly parts, namely, straight pipe section, straight pipe section with elbow, tee, B-shaped bend and differential section; the tee includes one main branch tee, main branch with two same-direction tees, main branch with two different-direction tees and main branch with three same-direction tees; the B-shaped bend includes a transverse B-shaped bend and a transverse and longitudinal B-shaped bend; the above-mentioned types of assembly parts respectively comply with the straight pipe section segmentation rules, the straight pipe section with elbow segmentation rules, the tee segmentation rules and the B-shaped bend segmentation rules, and the various types of assembly parts are divided according to the priority order based on the three-dimensional model of the assembled room air-conditioning water pipe, and the specific steps are as follows:

[0048] (1) Select the starting point of the segment. The starting point of the pipeline at the entrance of the machine room is used as the starting point of the segment. Figure 2 , a refrigeration room is divided into a unit of assembly construction. According to conventional design, the main line generally enters and exits the room and is also the main dividing line. Therefore, the import or export pipeline is selected as the starting end.

[0049] (2) Take X meters as a section and implement the following straight pipe segmentation rules: the length of the straight pipe section with elbow is X≤L-a2, a2 ​​is the minimum operating value corresponding to the pipe diameter D, when 100mm≤D<300mm, a2 is 200mm; when 300mm≤D≤600mm, a2 is 500mm; the axial distance value of the straight pipe section with elbow is Y≤B-a2, B is the limited value for transportation and packaging, when 100mm≤D<300mm, a2 is 400mm; when 300mm≤D≤600mm, a2 is 90 0mm; the short-circuit length of the straight pipe section with elbow flange is Y1=[b1,BR], b1 is the minimum operating value corresponding to the pipe diameter D, when 100mm≤D<300mm, b1 is 200mm; when 300mm≤D≤600mm, b1 is 250mm; R is the radius of curvature of the elbow, which is 1.5D or 1.0D; L is the common size of the pipe on the market, determined according to the standard size of the pipeline, such as 6000mm, 9000mm or 12000mm, and the feasibility of flexibly customizing L meters according to site conditions is also considered. B is limited to the transport width B according to the conventional size of the truck compartment, which is commonly 2200mm, but can be adjusted.

[0050] (3) If the pipe segment length does not meet X meters, determine whether it is an elbow. If so, execute the following straight pipe segment with elbow segment rules: the length of the straight pipe segment with elbow is X≤L-a2, a2 ​​is the minimum operating value corresponding to the pipe diameter D, when 100mm≤D<300mm, a2 is 200mm; when 300mm≤D≤600mm, a2 is 500mm; the axial distance value of the straight pipe segment with elbow is Y≤B-a2, B is the limited value for transportation and packaging, when 100mm≤D<300mm, a2 is 400mm; when 300m When m≤D≤600mm, a2 is 900mm; the short-circuit length of the straight pipe section with elbow flange is Y1=[b1,BR], b1 is the minimum operating value corresponding to the pipe diameter D, when 100mm≤D<300mm, b1 is 200mm; when 300mm≤D≤600mm, b1 is 250mm; R is the curvature radius of the elbow, which is 1.5D or 1.0D; L is determined according to the standard size of the pipeline, which is 6000mm, 9000mm or 12000mm; B is the transportation width limited by the conventional size of the truck compartment, which is 2200mm. Flanges are added to each port of the straight pipe section with elbow to generate the straight pipe section with elbow assembly, such as Figure 6 After completion, enter the straight pipe section again, such as Figure 5 If the pipe fitting is not an elbow, proceed to the next step. Figure 3 and Figure 6 As shown, the length and width of the pipe section must be less than or equal to the set transport length and transport width. The length and width are calculated based on the outermost edge of the flange, and the thickness of the gasket is not calculated. The length is based on the common pipe dimensions and the common truck packing length, and the width is based on the common truck packing width and the common allowable dimensions for transportation convenience. According to the common truck compartment dimensions, it is limited to the conventional transport width B, which is commonly 2.2m, but can be adjusted.

When 100mm ≤ D < 400mm, h2 is taken as 1500mm; when 400mm ≤ D ≤ 600mm, h2 is taken as 1000mm; L is determined according to the standard pipe size and is 6000mm, 9000mm or 12000mm.

[0054] When the main pipe branches into two tees in different directions, the length of the tee section is X≤L, and the distance between the branch pipe axis and the pipe end is X1=[a5,c2], where a5 is the minimum limit of the branch pipe spacing corresponding to the pipe diameter D. When 100mm≤D≤600mm, a5 is 300mm; c2 is the maximum limit of the branch pipe spacing corresponding to the pipe diameter D. When 100mm≤D<400mm, c2 is 1500mm, and when 400mm≤D≤600mm, c2 is 1000mm; the distance between the two branch pipe axes is X2≤L4, where L4 is the maximum limit of the tee branch spacing corresponding to the pipe diameter D. When 100mm≤D≤600mm, L4 is 4000mm; The length of the upward branch pipe is Y1≤L5, L5 is the maximum limit of the upward branch pipe of the tee corresponding to the pipe diameter D, when 100mm≤D≤600mm, L5 is 500mm, the length of the horizontal branch pipe is Y2≤L6, L6 is the maximum limit of the horizontal branch pipe of the tee corresponding to the pipe diameter D, when 100mm≤D≤600mm, L6 is 1000mm; the vertical height difference between the branch pipe end and the main pipe axis Z≤h3, when 100mm≤D<400mm, h3 is 1500mm; when 400mm≤D≤600mm, h3 is 1000mm, L is determined according to the standard size of the pipeline, which is 6000mm, 9000mm or 12000mm;

L is determined according to the standard size of the pipeline, which is 6000mm, 9000mm or 12000mm.

[0056] Add flanges to the main pipe end and branch pipe end of the tee to generate a tee assembly. After completion, enter the straight pipe segmentation again. In addition, take the branch pipe end of the tee as the starting point and start segmentation from step (2). If the pipe fitting is not a tee, proceed to the next step. The tee division has a greater impact on the positioning of the branch, so it is better to make it a separate component, with a tee for the main pipe branch (such as Figure 7), main branch with 2 same-direction tees (such as Figure 8 ), main branch with 2 different direction tees (such as Fig. 9 ), main branch with 3 same-direction tees (such as Fig.10 ) Four types, in addition, the space requirement for welding at the penetration of TY water-saving tee needs to be limited to a minimum value.

[0057] (5) If the pipe is a B-shaped bend, the following B-shaped bend segmentation rules are implemented:

[0058] For the transverse B-shaped bend in pipe diameter D, when 100mm≤D<400mm, the B-shaped bend adopts an angle less than 90 degrees, the total length X≤L, the length of the straight pipe section X1 / X2≤L8, L8 is the maximum limit of the small angle of the transverse B-shaped bend, which is 2500mm; when 400mm≤D≤600mm, the length of the B-shaped bend X≤B, the B-shaped bend adopts a 90-degree angle, the distance value of the end face of the B-shaped bend from the vertical centerline X1 / X2≤L9, L9 is the maximum limit of the 90-degree transverse B-shaped bend, which is 1000mm, and L is determined according to the standard size of the pipeline, which is 6000mm, 9000mm or 12000mm; B is the transportation width limited by the conventional size of the truck compartment, which is 2200mm;

[0059] The distance X / Y between the end face of the transverse and longitudinal B-shaped bend and the axis center of the corner is ≤L10, where L10 is the maximum limit of the small angle of the transverse B-shaped bend. The transverse and longitudinal B-shaped bend pipe diameter D, when 100mm≤D<350mm, L10 is 2000mm, and when 350mm≤D≤400mm, L10 is 1900mm; the longitudinal height difference Z of the transverse and longitudinal B-shaped bend is ≤h5, when 100mm≤D≤400mm, h5 is 1000mm, and when the pipe diameter D is above 400mm, it cannot be classified as a B-shaped bend; L is determined according to the standard size of the pipeline, which is 6000mm, 9000mm or 12000mm.

[0060] Add flanges to the ends of the B-shaped components to generate B-shaped assembly parts, such as Fig.11a , Fig.11b and Fig.12a , Figure 12b As shown, after completion, enter the straight pipe section again. Figure 4 As shown in the figure, the error caused by the change of the horizontal or vertical elevation of the B-shaped bend is not convenient for assembly transportation, so the data needs to be restricted. It is necessary to compare the three values ​​of x, y, and z, and select the largest one as the transportation length, and the second one as the transportation width. The result must meet the length and width limits.

[0061] (6) If the straight pipe section encounters the end of the pipeline or the equipment valve, the segmentation of the assembled component is terminated.

[0062] (7) If the straight pipe section with elbow is the last component, it is defined as the differential adjustment section, and no flange is added. Considering the probability of error occurrence and the difficulty of correction, the straight pipe section is the part where the error is easier to control and easier to correct. Therefore, it is carried out according to the priority of straight pipe section, pipe with elbow, pipe with tee, pipe with oblique tee, and U-shaped bend. The component between the equipment interface and the valve is defined as the differential adjustment section, and no flange is added. Because the pipelines are generally arranged horizontally and vertically and compactly, the branch pipeline is turned up to avoid the main pipeline and then connected to the equipment in the vertical direction. Since the main pipeline has a large diameter and it is not easy to correct the error, the pipe section between the equipment interface and the valve is selected as the differential adjustment section, which is more operable.

[0063] (8) Overall determine whether the added flanges meet the requirements of alignment in the same position or alignment in odd and even positions, and whether the flange ports of the same type of branch pipes maintain the same elevation and position. If not, adjust the length of the pipe section and the position of the flange.

[0064] (9) Overall determine whether the principle of the flange not colliding with the bracket is met. If not, adjust the length of the pipe section and the position of the flange. At this point, the division of the assembly components is completed.
