Description

Technical Field

[0001] This application relates to the field of pipe connection technology, and more particularly to a welding calibration device. Background Technology

[0002] Currently, pneumatic duct sample conveying devices are widely used in factories as a highly efficient and convenient directional transport equipment for small samples, improving conveying efficiency while reducing transportation costs. During production operations, due to various uncertainties, it is inevitable that some damaged sections of the duct will need to be replaced.

[0003] In related technologies, replacing individual damaged pipes requires working at a high altitude close to the individual pipes to ensure that the welding positions of the flanges at both ends of the new pipes are accurate and to avoid problems such as the inability to install the new pipes smoothly.

[0004] However, the height of the pipe racks near the pipelines can generally reach 20 meters, and high-risk pipelines such as gas pipelines are often arranged near the pipe racks, which leads to technical problems such as high difficulty of operation, high risk factor and high management cost for high-altitude operations. Summary of the Invention

[0005] The first aspect of this application provides a welding calibration device. This device calibrates the welding position of a target flange on a target pipeline based on the position of an original flange on an original pipeline. The welding calibration device includes multiple calibration components, each including a support mechanism and a calibration flange. The calibration flange is disposed on the support mechanism, which can drive the calibration flange to move, thereby adjusting the position and angle of the calibration flange. The welding calibration device can initially position the calibration flange by connecting it to the original flange, and can also calibrate the welding position of the target flange on the target pipeline by connecting the initially positioned calibration flange to the target flange.

[0006] This application defines a welding calibration device that can operate on the ground. The welding calibration device can calibrate the welding position of the target flange of the target pipe to be replaced according to the position of the original flange on the removed original pipe, so that the calibrated target pipe can be directly connected to the corresponding position through the target flange, eliminating the high-altitude operation scenario mentioned in related technologies.

[0007] The welding calibration equipment includes multiple calibration components, including a support mechanism and a calibration flange. The calibration flange is mounted on the support mechanism, which supports and positions the calibration flange so that the position and angle of the calibration flange are consistent with the position and angle of the original flange. The calibration flange is detachably connected to the support mechanism, and users can replace it with different models of calibration flanges according to actual needs to expand the applicability of the product.

[0008] The number of calibration components is the same as the number of connecting flanges on the target pipe that needs to be replaced. For example, when replacing a double-ended target pipe, two calibration components are used to calibrate the welding positions of the two target flanges at both ends of the target pipe. When replacing a four-way pipe, four calibration components can be used to calibrate the welding positions of the four target flanges on the four connecting ends of the target pipe. The same applies to other types of target pipes, which will not be elaborated here. Furthermore, this technical solution does not impose a hard limit on the specific number of calibration components.

[0009] Specifically, multiple calibration components are arranged on the ground. When it is necessary to replace a section of the original pipe on the pneumatic duct, the user first removes the original pipe from the pneumatic duct and connects the original flanges on the original pipe to the calibration flanges on the multiple calibration components. During the connection process, the position and angle of the calibration flanges need to be adjusted with reference to the original flanges. Once the connection between the two is completed, the initial positioning of the calibration flange is completed.

[0010] After initially positioning the multiple calibration flanges on multiple calibration components using the disassembled original pipes, the multiple target flanges to be replaced are connected to the corresponding calibration flanges. Since the position and angle of the calibration flanges have been initially positioned with reference to the position and angle of the original flanges, the angle and position of the target flanges after connection are consistent with the angle and position of the original flanges, thus completing the calibration of the welding positions of the multiple target flanges. Subsequently, the multiple ends of the target pipe are welded to the multiple target flanges to complete the preparation of the target pipe, allowing the user to directly install the target pipe in the position corresponding to the original pipe, thereby completing the replacement of the pneumatic pipe.

[0011] Therefore, the welding calibration equipment proposed in this application can use the disassembled original pipeline to complete the calibration of the welding position of the target flange on the target pipeline on the ground, so as to obtain a target pipeline that is consistent with the original pipeline. This allows the target pipeline to be directly installed at the location of the original pipeline without on-site calibration, eliminating the need for users to perform end-to-end calibration welding operations on the target pipeline in high-altitude areas such as pipe racks.

[0012] Compared to high-altitude work environments such as utility tunnels, ground-based operations offer a larger operating space, thus reducing operational difficulty and management costs. Furthermore, ground-based operations are not subject to interference from other high-risk pipelines and eliminate the risks of falls or falling objects, thereby lowering the operational hazard factor. This addresses the technical challenges of high operational difficulty, high risk, and high management costs inherent in related technologies. It achieves the technical effect of reducing the difficulty and cost of maintaining pneumatic ducts while ensuring the personal safety of workers.

[0013] In addition, the calibration device provided by the present invention may also have the following additional technical features:

[0014] In some technical solutions of the present invention, optionally, the number of calibration components is two, the calibration flanges on the two calibration components are arranged opposite to each other, the support mechanism can adjust the distance between the two calibration flanges by driving the calibration flanges to move, and the support mechanism can also adjust the angle between the two calibration flanges by driving the calibration flanges to rotate along the axis.

[0020] In some technical solutions of the present invention, the support mechanism may optionally include: a limiting member disposed on the base and connected to the central shaft, the limiting member being used to limit the central shaft in the radial direction and the axial direction of the central shaft.

[0021] In some technical solutions of the present invention, optionally, the limiting member includes: a bushing disposed on the base, the bushing being sleeved on the outside of the central shaft, the bushing including a threaded hole communicating the inner and outer sides of the bushing; and a locking nut passing through the threaded hole.

Detailed Implementation

[0038] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0039] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0040] The following is combined with Figures 1 to 12 This application describes a welding calibration apparatus (100) and a welding calibration method according to embodiments thereof.

[0041] like Figure 1 , Figure 7 and Figure 9As shown, one embodiment of the present invention provides a welding calibration device 100. The welding calibration device 100 is used to calibrate the welding position of a target flange 310 on a target pipe 300 based on the position of an original flange 210 on an original pipe 200. The welding calibration device 100 includes multiple calibration components 110, each including a support mechanism 112 and a calibration flange 114. The calibration flange 114 is disposed on the support mechanism 112, which can drive the calibration flange 114 to move, thereby adjusting the position and angle of the calibration flange 114. The welding calibration device 100 can initially position the calibration flange 114 by connecting it to the original flange 210. Furthermore, the welding calibration device 100 can calibrate the welding position of the target flange 310 on the target pipe 300 by connecting the initially positioned calibration flange 114 to the target flange 310.

[0042] This application defines a welding calibration device 100 capable of ground-based operations, applicable to pneumatic ductwork. Pneumatic ductwork is typically installed inside pipe racks, approximately 20 meters high, which are densely packed with pipes, including various flammable gas transport pipes. Replacing a single section of a pneumatic duct requires on-site hot work on the flanges. According to the special operations classification and control requirements, this hot work operation, at a height of 20 meters and located in a gas area, falls under the category of Level 1 hot work. Therefore, the project manager must prepare a fire safety technical plan, complete a hot work application form, and obtain approval from the company's safety management department before hot work can commence. The operation carries a high risk level, is difficult to maintain, and incurs high management costs.

[0043] In this regard, the welding calibration equipment 100 proposed in this application can calibrate the welding position of the target flange 310 of the target pipe 300 to be replaced according to the position of the original flange 210 on the removed original pipe 200, so that the calibrated target pipe 300 can be directly connected to the corresponding position through the target flange 310, eliminating the high-altitude operation scenario mentioned in the related technology.

[0044] The welding calibration equipment 100 includes multiple calibration components 110. Each calibration component 110 includes a support mechanism 112 and a calibration flange 114. The calibration flange 114 is mounted on the support mechanism 112, which supports and positions the calibration flange 114 so that its position and angle are consistent with those of the original flange 210. The calibration flange 114 is detachably connected to the support mechanism 112, and users can replace it with different models of calibration flange 114 according to actual needs to expand the applicability of the product.

[0045] The number of calibration components 110 is the same as the number of connecting flanges on the target pipe 300 that needs to be replaced. For example, when replacing a double-ended target pipe 300, the welding positions of the two target flanges 310 at both ends of the target pipe 300 are calibrated using two calibration components 110. When replacing a four-way pipe, the welding positions of the four target flanges 310 on the four connecting ends of the target pipe 300 can be calibrated using four calibration components 110. The same applies to other types of target pipes 300, which will not be elaborated here. Furthermore, this embodiment does not impose a hard limit on the specific number of calibration components 110.

[0046] Specifically, multiple calibration components 110 are arranged on the ground. When it is necessary to replace a section of the original pipe 200 on the pneumatic duct, the user first removes the original pipe 200 from the pneumatic duct and connects the multiple original flanges 210 on the original pipe 200 to the calibration flanges 114 on the multiple calibration components 110 respectively. During the connection process, the position and angle of the calibration flange 114 need to be adjusted with reference to the original flange 210. The initial positioning of the calibration flange 114 is completed after the connection between the two is completed.

[0047] After initially positioning the multiple calibration flanges 114 on the multiple calibration components 110 using the disassembled original pipe 200, the multiple target flanges 310 to be replaced are connected to the multiple calibration flanges 114 accordingly. Since the position and angle of the calibration flanges 114 have been initially positioned with reference to the position and angle of the original flange 210, the angle and position of the target flanges 310 after connection are consistent with the angle and position of the original flange 210, thus completing the calibration of the welding position of the multiple target flanges 310. Subsequently, the multiple ends of the target pipe 300 are welded together with the multiple target flanges 310 to complete the preparation of the target pipe 300, allowing the user to directly install the target pipe 300 at the position corresponding to the original pipe 200, thereby completing the replacement of the pneumatic pipe.

[0048] Therefore, the welding calibration equipment 100 proposed in this application can use the disassembled original pipe 200 to complete the calibration of the welding position of the target flange 310 on the target pipe 300 on the ground, so as to obtain a target pipe 300 that is consistent with the original pipe 200. This allows the target pipe 300 to be directly installed at the location of the original pipe 200 without on-site calibration, eliminating the need for users to perform end-to-end calibration welding of the target pipe 300 in high-altitude areas such as pipe racks.

[0049] Compared to high-altitude work environments such as utility tunnels, ground-based operations offer a larger operating space, thus reducing operational difficulty and management costs. Furthermore, ground-based operations are not subject to interference from other high-risk pipelines and eliminate the risks of falls or falling objects, thereby lowering the operational hazard factor. This addresses the technical challenges of high operational difficulty, high risk, and high management costs inherent in related technologies. It achieves the technical effect of reducing the difficulty and cost of maintaining pneumatic ducts while ensuring the personal safety of workers.

[0050] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of the present invention, optionally, the number of calibration components 110 is two, the calibration flanges 114 on the two calibration components 110 are arranged opposite to each other, the support mechanism 112 can adjust the distance between the two calibration flanges 114 by driving the calibration flanges 114 to move, and the support mechanism 112 can also adjust the angle of the two calibration flanges 114 by driving the calibration flanges 114 to rotate along the axis.

[0051] In this embodiment, the welding calibration equipment 100 is used to replace a section of the original pipe 200 in the pneumatic duct. The pneumatic duct is formed by connecting multiple pipe sections in series. Each pipe section includes two ports, and two flanges are installed at the two ports respectively. The flanges connect adjacent pipe sections.

[0052] Based on this, the welding calibration equipment 100 replaces the straight pipe in the middle section of the pneumatic duct. The welding calibration equipment 100 includes two calibration components 110, which correspond to the two flanges installed at both ends of the original pipe 200.

[0053] Two calibration components 110 are positioned opposite each other, aligning two calibration flanges 114 to accommodate the straight-lined original pipe 200. A support mechanism 112 can move the calibration flanges 114 to adjust their relative positions. For example, after positioning the two calibration flanges 114 opposite each other, the support mechanism 112 can move the calibration flanges 114 along their axial direction to adjust the distance between them, thus accommodating target pipes 300 of different lengths. This completes the initial positioning of the calibration flanges 114 and the calibration of the target flange 310. Furthermore, the support mechanism 112 can also rotate the calibration flanges 114 around their own axis to adjust their angle. This allows the calibration flanges 114 to achieve initial angular positioning by aligning with the original flange 210 and to complete the angular calibration of the target flange 310 by aligning with it.

[0054] It can be seen that by setting two calibration components 110, the ground calibration requirements of one section of straight pipe on the pneumatic duct can be met. This allows users to complete the calibration of the target flange 310 and the welding of the target pipe 300 on the ground after removing the original pipe 200, with the help of the two calibration components 110. This reduces high-altitude operations, thereby reducing the difficulty and cost of pneumatic duct maintenance and ensuring the personal safety of operators.

[0055] like Figure 4 As shown, in some embodiments of the present invention, optionally, the welding calibration device 100 further includes: a calibration platform 120, including a slide 122, the slide 122 extending in a straight direction, and a support mechanism 112 slidably connected to the slide 122; and a locking mechanism 130 disposed on the support mechanism 112, the locking mechanism 130 being used to lock the support mechanism 112 onto the slide 122.

[0056] In this embodiment, the welding calibration equipment 100 further includes a calibration platform 120, on which two calibration components 110 are disposed. The calibration platform 120 is used to provide positioning and support for the two calibration components 110.

[0057] Specifically, the calibration platform 120 is equipped with a slide rail 122, which extends in a straight line to accommodate the welding calibration requirements of straight pipes. The support mechanism 112 is slidably connected to the slide rail 122, allowing the support mechanism 112 to slide along the slide rail 122. This allows adjustment of the distance between the two calibration flanges 114 via the slide rail 122, thus accommodating target pipes 300 of different lengths. By incorporating the slide rail 122 into the calibration platform 120, the difficulty for users to adjust the position of the calibration component 110 is reduced, thereby improving the user experience.

[0058] Based on this, a locking mechanism 130 is also provided on the support mechanism 112. The locking mechanism 130 is adapted to the slide rail 122. The locking mechanism 130 is used to lock the support mechanism 112 in a designated position on the slide rail 122 to prevent the calibration component 110 from moving during operation, thereby improving the calibration accuracy of the target flange 310 and ensuring that the target pipe 300 can be smoothly installed on the pneumatic pipe, thereby achieving the technical effect of improving the reliability of the welding calibration equipment 100.

[0059] Specifically, the locking mechanism 130 includes an openable locking clip that controls the locking clip to clamp the slide rail 122 when it is necessary to lock the support mechanism 112, so as to achieve the locking effect of the support mechanism 112 by increasing the resistance.

[0060] like Figure 4As shown, in some embodiments of the present invention, the welding calibration device 100 may optionally include a distance measuring mechanism 140 disposed on the calibration component 110, the distance measuring mechanism 140 being used to measure the distance between two calibration components 110.

[0061] In this embodiment, the welding calibration equipment 100 also includes a distance measuring mechanism 140, which is disposed on the two calibration components 110. The distance measuring mechanism 140 can measure the distance between the two calibration components 110 during operation. Specifically, the distance is the distance between the two calibration flanges 114, or it can be the distance between other parts on the two calibration components 110. The distance between the two calibration flanges 114 is then calculated from the distance between these other parts.

[0062] After measuring the distance between the two calibration flanges 114 by the ranging mechanism 140, the length of the target pipe 300 can be precisely controlled by this distance, avoiding the length error of the target pipe 300 from affecting the installation of the target pipe 300, thereby achieving the technical effect of improving the calibration accuracy and reliability of the welding calibration equipment 100.

[0063] Specifically, the ranging mechanism 140 is a laser rangefinder, which includes a transmitter and a receiver. The transmitter is mounted on one of the calibration flanges 114, and the receiver is mounted on the other calibration flange 114, with the two positioned opposite each other. The transmitter and receiver need to avoid the connection surfaces of the calibration flanges 114. Specifically, they can be located in a through hole in the center of the calibration flange 114, or they can be located on the periphery of the calibration flange 114. When located on the periphery of the calibration flange 114, the transmitter and receiver are detachable to prevent misalignment after the calibration flange 114 is rotated.

[0064] like Figure 5 As shown, in some embodiments of the present invention, optionally, a wheel 150 is provided at the bottom of the support mechanism 112.

[0065] In this embodiment, a wheel 150 is provided at the bottom of the support mechanism 112. By providing the wheel 150 on the support mechanism 112, the resistance between the support mechanism 112 and the ground can be reduced, making it convenient for the user to adjust the position of the calibration component 110 and achieving the technical effect of improving the practicality of the welding calibration equipment 100.

[0066] Specifically, the wheel 150 has a self-locking function. When the user moves the calibration component 110 to a designated position, the user can lock the wheel 150 to prevent the calibration component 110 from moving.

[0067] like Figure 2 and Figure 3As shown, in some embodiments of the present invention, optionally, the support mechanism 112 includes: a base 1122; a central shaft 1124 slidably connected to the base 1122; a calibration flange 114 disposed at the first end of the central shaft 1124; the central shaft 1124 is capable of sliding along the axial direction; and the central shaft 1124 is also capable of rotating around the axis.

[0068] In this embodiment, the support mechanism 112 includes a base 1122 and a central shaft 1124. The central shaft 1124 is mounted on the base 1122. The base 1122 can be placed directly on the ground, or it can be slidably connected to the slide rail 122, or a wheel 150 can be installed under the base 1122.

[0069] The central shaft 1124 is mounted on the base 1122 and can slide along the axial direction on the base 1122. By controlling the sliding of the central shaft 1124, the position of the calibration flange 114 can be adjusted. Specifically, after locking the base 1122, the distance between the two calibration flanges 114 can be finely adjusted by controlling the sliding of the central shaft 1124 to precisely control the length of the target pipe 300.

[0070] Based on this, the central shaft 1124 can also rotate around its own axis on the base 1122. After assembly, the axis of the calibration flange 114 coincides with the axis of the central shaft 1124. By controlling the rotation of the central shaft 1124, the angle of the calibration flange 114 can be adjusted synchronously, so that the calibration flange 114 after calibration can be aligned with the original flange 210, ensuring that the calibrated target flange 310 can be successfully connected to the wind-driven pipeline.

[0071] In summary, by setting the central axis 1124, the calibration accuracy of the target flange 310 on the target pipeline 300 can be improved, thereby achieving the technical effect of improving the reliability of the welding calibration equipment 100.

[0072] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the support mechanism 112 may optionally include: a plurality of bearing members 1126 disposed on the base 1122, the plurality of bearing members 1126 being spaced apart along the same axis, and a central shaft 1124 passing through the plurality of bearing members 1126; and a handle 1128 disposed at the second end of the central shaft 1124.

[0073] In this embodiment, a plurality of bearing components 1126 are provided on the base 1122. The plurality of bearing components 1126 are spaced apart along the same axis. The assembly of the central shaft 1124 is completed by inserting the central shaft 1124 through the plurality of bearing components 1126. The plurality of bearing components 1126 jointly support the central shaft 1124, and the bearings can reduce the rotational resistance of the central shaft 1124 during rotation.

[0074] The number of bearing components 1126 can be adjusted according to the length of the central shaft 1124.

[0075] Based on this, the first end of the central shaft 1124 is used to connect to the calibration flange 114, and the second end of the central shaft 1124 is used to connect to the handle 1128. The handle 1128 can be gripped by the user. When it is necessary to adjust the position of the calibration flange 114, the user can push and pull the handle 1128 to drive the central shaft 1124 to slide. When it is necessary to adjust the angle of the calibration flange 114, the user can rotate the handle 1128 to drive the central shaft 1124 to rotate.

[0076] Therefore, by setting handle 1128, users can conveniently adjust the position and angle of calibration flange 114, thereby improving the practicality of welding calibration equipment 100 and enhancing the user experience.

[0077] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the support mechanism 112 may optionally include a limiting member 1129, disposed on the base 1122 and connected to the central shaft 1124, the limiting member 1129 being used to limit the central shaft 1124 in the radial direction and the axial direction of the central shaft 1124.

[0078] In this embodiment, a limiting member 1129 is also provided on the base 1122. The limiting member 1129 cooperates with the central shaft 1124. The limiting member 1129 can lock the central shaft 1124 on the base 1122 to prevent the central shaft 1124 from sliding and rotating.

[0079] By setting the limiting component 1129, the calibration flange 114 can be locked after the initial positioning is completed, so as to prevent the calibration flange 114 from moving or rotating in subsequent operations, thereby improving the calibration accuracy of the target flange 310 and ensuring that the target pipeline 300 can be connected to the pneumatic pipeline through the target flange 310.

[0080] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, optionally, the limiting member 1129 includes: a bushing 11292 disposed on the base 1122, the bushing 11292 being sleeved on the outside of the central shaft 1124, the bushing 11292 including a threaded hole communicating the inner and outer sides of the bushing 11292; and a locking nut 11294 passing through the threaded hole.

[0081] In this embodiment, the limiting member 1129 includes a bushing 11292 and a locking nut 11294. The bushing 11292 is fixed on the base 1122 and has a radially penetrating screw hole. After assembly, the bushing 11292 is fitted onto the outside of the central shaft 1124. The locking nut 11294 is screwed into the screw hole. When it is necessary to lock the central shaft 1124, the screwing depth of the locking nut 11294 is increased until the end of the locking nut 11294 is pressed tightly against the outer surface of the central shaft 1124, so as to lock the central shaft 1124 through the locking nut 11294.

[0082] By setting the bushing 11292 and the locking nut 11294, the calibration flange 114 can be locked after the initial positioning is completed, ensuring that the position and angle of the calibration flange 114 are accurate, thereby achieving the technical effect of improving the calibration accuracy of the target flange 310 and improving the installation success rate of the target pipeline 300.

[0083] like Figure 12 As shown, a second aspect of this application provides a welding calibration method for calibrating the welding position of a target flange 310 using a welding calibration device 100 as described in any of the above embodiments. The welding calibration device 100 includes two calibration components 110, and the welding calibration method includes:

[0084] Step 1202: Connect the two original flanges at both ends of the original pipeline to the calibration flanges on the two calibration components respectively;

[0085] Step 1204: Remove the original pipe;

[0086] Step 1206: Connect the two target flanges to the calibration flanges on the two calibration components respectively;

[0087] Step 1208: Weld both ends of the target pipe to the two target flanges respectively.

[0088] In this embodiment, a welding calibration method is defined to control the welding calibration equipment in any of the above embodiments to perform calibration operations. Therefore, the welding calibration method has the technical features included in the welding calibration equipment in any of the above embodiments and can achieve the technical effects that the welding calibration equipment in any of the above embodiments can achieve. To avoid repetition, it will not be described again here.

[0089] Based on this, welding calibration methods include:

[0090] like Figure 6 and Figure 7As shown, when it is necessary to replace a section of the original pipe 200 on the pneumatic duct, the user first removes the original pipe 200 from the pneumatic duct, and then connects the multiple original flanges 210 on the original pipe 200 to the calibration flanges 114 on the multiple calibration components 110 respectively. During the connection process, the position and angle of the calibration flange 114 need to be adjusted with reference to the original flange 210. The initial positioning of the calibration flange 114 is completed after the connection between the two is completed.

[0091] like Figure 8 , Figure 9 and Figure 10 As shown, after initially positioning the multiple calibration flanges 114 on the multiple calibration components 110 using the disassembled original pipe 200, the multiple target flanges 310 that need to be replaced are connected to the multiple calibration flanges 114 accordingly. Because the position and angle of the calibration flanges 114 have been initially positioned with reference to the position and angle of the original flanges 210, the angle and position of the target flanges 310 after connection are consistent with the angle and position of the original flanges 210, thus completing the calibration of the welding positions of the multiple target flanges 310. Figure 11 As shown, the target pipe 300 can be prepared by welding multiple ends of the target pipe 300 to multiple target flanges 310 respectively, so that the user can directly install the target pipe 300 at the position corresponding to the original pipe 200, thereby completing the replacement of the pneumatic pipe.

[0092] Therefore, the welding calibration method proposed in this application can use the disassembled original pipe 200 to complete the calibration of the welding position of the target flange 310 on the target pipe 300 on the ground, so as to obtain a target pipe 300 that is consistent with the original pipe 200. This allows the target pipe 300 to be directly installed at the location of the original pipe 200 without on-site calibration, eliminating the need for users to perform end-to-end calibration welding of the target pipe 300 in high-altitude areas such as pipe racks.

[0093] Compared to high-altitude work environments such as utility tunnels, ground-based operations offer a larger operating space, thus reducing operational difficulty and management costs. Furthermore, ground-based operations are not subject to interference from other high-risk pipelines and eliminate the risks of falls or falling objects, thereby lowering the operational hazard factor. This addresses the technical challenges of high operational difficulty, high risk, and high management costs inherent in related technologies. It achieves the technical effect of reducing the difficulty and cost of maintaining pneumatic ducts while ensuring the personal safety of workers.
