Description

Technical Field

[0001] The utility model relates to the technical field of pipeline production and manufacturing, in particular to a welding auxiliary tool for a pipeline structure. Background Art

[0002] In the manufacturing process of pipeline structures such as automotive air-conditioning pipes, it is usually necessary to use flame brazing to butt-connect an aluminum pipeline with a flange joint. Specifically, when welding the pipeline and the flange joint, it is necessary to first butt-connect the required flange joint with the end face of the aluminum pipe, and then use a flame to heat the brazing wire at the butted end face. Subsequently, the brazing wire will melt and fill between the butted end faces. After the melted brazing wire cools down, the welding of the pipeline structure is completed.

[0003] However, since the flame temperature during flame brazing is relatively high, and the position of the part to be heated on the pipeline structure is relatively large, resulting in a relatively long required flame length, there are fixed space requirements when welding the flange joint and the pipeline. The welding surfaces of the welded flange joint and the welded pipeline must both be vertical surfaces. Therefore, in the welding process of the pipeline and the flange in the pipeline structure, a welding auxiliary device is required to support and assist the positions of the pipeline and the flange.

[0004] The existing welding auxiliary device for pipeline structures uses multiple fire-resistant lifting structures to lift the flange and the pipeline respectively. And in order to ensure that the pipeline layout conforms to the pipeline design, there are usually multiple lifting structures under the pipeline, and these multiple lifting structures are distributed in sequence along the pipeline layout. In addition, the existing welding auxiliary device for pipeline structures also includes a fire-resistant bottom plate, and the above-mentioned lifting structures are all fixed to the fire-resistant bottom plate by first inserting and then welding.

[0005] However, the layouts of different pipelines are different. The welding auxiliary device for pipeline structures used to produce pipeline structures of the same model is only applicable to pipeline structures of that model, and pipeline structures of other models cannot be borrowed. Also, due to the high overall cost of fire-resistant materials, when producing pipeline structures of different models, multiple welding auxiliary devices for pipeline structures need to be set up correspondingly, greatly increasing the manufacturing cost. And in order to make the pipeline layout conform to the design, the hole positions on the bottom plate must be accurate, which will also increase the manufacturing cost. In addition, each part in the existing welding auxiliary device for pipeline structures is fixedly connected by welding, resulting in a large overall weight and being inconvenient for the operator to move. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a welding auxiliary tooling for pipeline structures, so as to alleviate the technical problems existing in the prior art that the welding auxiliary devices for pipeline structures usually only apply to pipeline structures of the same model. When producing pipeline structures of different models, a variety of welding auxiliary devices for pipeline structures need to be correspondingly set, which greatly increases the manufacturing cost; and in order to make the pipeline routing conform to the design, the opening positions on the bottom plate must be precise, which will also increase the manufacturing cost; in addition, each part in the welding auxiliary device for pipeline structures is fixedly connected by welding, with a large overall weight and being inconvenient for the operator to move.

[0030] The welding auxiliary tooling for the pipeline structure provided by the utility model includes a flange lifting component, a pipeline lifting component and a support base plate; the flange lifting component is fixed on the support base plate by a threaded connection method, and the flange lifting component is used for detachably connecting with the flange to be welded, so that the welding surface of the flange is perpendicular to the support base plate; the pipeline lifting component includes a base and a plurality of support members, the base is installed at any position on the support base plate by a magnetic attraction method, and the plurality of support members are respectively connected with the base through a position adjustment structure, and the position adjustment structure is used for adjusting the spatial position of the support member connected thereto, so that the plurality of support members can be distributed in sequence along the designed trend of the pipeline to be welded; the plurality of support members are all used for supporting the pipeline to be welded, so that the welding surface of the pipeline is perpendicular to the support base plate. The welding auxiliary tooling for the pipeline structure provided by the utility model is applied to the welding operation of pipeline structures such as air-conditioning pipes. Before the welding operation, the flange lifting component can be fixed on the support base plate by a threaded connection method, and the flange to be welded can be connected with the flange lifting component by a detachable method such as plugging, clamping or threaded connection, and at the same time, the welding surface of the flange needs to be perpendicular to the support base plate. Then, the base in the pipeline lifting component can be fixed on the support base plate by a magnetic attraction method, and at the same time, according to the designed trend of the pipeline to be welded, the spatial positions of the plurality of support members can be adjusted respectively by using the plurality of position adjustment structures until the plurality of support members are distributed in sequence along the designed trend of the pipeline. Then, the pipeline to be welded can be connected with the plurality of support members in sequence, and at the same time, the welding surface of the pipeline to be welded also needs to be perpendicular to the support base plate. If the welding surface of the pipeline to be welded is butted against the welding surface of the flange to be welded at this time, there is no need to adjust the position of the base of the pipeline lifting component any more; if there is a gap between the welding surface of the pipeline to be welded and the welding surface of the flange to be welded at this time, the position of the base in the pipeline lifting component can be moved on the support base plate until the welding surface of the pipeline is butted against the welding surface of the flange. It should be noted that since the base is fixed on the support base plate by a magnetic attraction method, the position of the base can be adjusted arbitrarily on the support base plate and can be kept fixed after adjustment. Therefore, the welding surface of the pipeline and the welding surface of the flange can be kept in the butted state after butt joint, which is convenient for the subsequent welding operation. When using this tooling for the welding operation of pipeline structures of different models, since this tooling can adjust the spatial position of the support members through the position adjustment structure so that the distribution position of the support members conforms to the designed trend of the pipeline in the pipeline structure, and the position of the base on the support base plate can be adjusted arbitrarily so that the welding surface of the pipeline in the pipeline structure can be butted against the welding surface of the flange, this tooling can be applied to the welding operation of pipeline structures of different models, and only the positions of the support members and the base need to be debugged during the welding process, and there is no need to set different welding auxiliary devices for pipeline structures of different models, effectively reducing the manufacturing cost.Moreover, the pipeline lifting component in the pipeline structure welding auxiliary tooling is fixed on the support base plate by magnetic attraction, without being inserted into the support base plate. Therefore, there is no need to accurately drill holes in the support base plate, which also effectively reduces the manufacturing cost of the tooling. In addition, in the pipeline structure welding auxiliary tooling provided by the present utility model, whether it is the flange lifting component or the pipeline lifting component, they are all detachably connected to the support base plate. Therefore, when transferring the pipeline structure welding auxiliary tooling, the structure of the tooling can be disassembled first and then moved separately, without moving the whole tooling, thus effectively improving the convenience of use for the operator.

[0031] Compared with the prior art, the pipeline structure welding auxiliary tooling provided by the present utility model connects the base and the support base plate by magnetic attraction and can flexibly adjust the spatial position of the support member through the position adjustment structure, so that the pipeline lifting component can adapt to different types of pipeline structures. Therefore, the tooling is applicable to different types of pipeline structures, without the need to manufacture different specifications of tooling according to different types of pipeline structures, effectively reducing the manufacturing cost of the tooling. At the same time, the magnetic attraction method enables the pipeline lifting component to be stably fixed on the support base plate, without the need to insert and weld the pipeline lifting component to the support base plate. Correspondingly, there is no need to accurately drill holes in the support base plate, further effectively reducing the manufacturing cost. In addition, the pipeline structure welding auxiliary tooling connects the flange lifting component and the support base plate by screw threads, and connects the pipeline lifting component and the support base plate by magnetic attraction, so that the whole tooling can be disassembled, thus facilitating the separate movement of each structure of the tooling when transferring the tooling, effectively improving the convenience of movement for the operator.

[0039] The following will describe in detail some implementation modes of the present utility model in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0040] Embodiment:

[0041] As Figure 1 shown, the pipeline structure welding auxiliary tooling provided in this embodiment includes a flange lifting assembly 1, a pipeline lifting assembly 2 and a support base plate 3; the flange lifting assembly 1 is fixed to the support base plate 3 by a threaded connection method, and the flange lifting assembly 1 is used for detachably connecting with the flange to be welded, so that the welding surface of the flange is perpendicular to the support base plate 3; the pipeline lifting assembly 2 includes a base 20 and a plurality of support members 21, the base 20 is installed at any position of the support base plate 3 by a magnetic attraction method, and the plurality of support members 21 are respectively connected with the base 20 through a position adjusting structure 22, and the position adjusting structure 22 is used to adjust the spatial position of the support member 21 connected thereto, so that the plurality of support members 21 can be distributed in sequence along the designed direction of the pipeline to be welded; the plurality of support members 21 are all used to support the pipeline to be welded, so that the welding surface of the pipeline is perpendicular to the support base plate 3.

[0042] The pipe structure welding auxiliary tooling provided in this embodiment is applied to the welding operation of pipe structures such as air-conditioning pipes. Before the welding operation, the flange lifting assembly 1 can be fixed to the support base plate 3 by means of threaded connection, and the flange to be welded is connected to the flange lifting assembly 1 by detachable means such as plugging, clamping or threaded connection. At the same time, the welding surface of the flange needs to be perpendicular to the support base plate 3.

[0043] It should be noted that the flange to be welded and the pipe to be welded in the pipe structure usually need to be butt-connected and communicated first before welding. Based on this, the side of the flange to be welded that can be butt-connected to the pipe to be welded is the flange welding surface, and the side of the pipe to be welded that can be butt-connected to the flange to be welded is the pipe welding surface. When welding the flange to be welded and the pipe to be welded in the pipe structure, one of the positions of the flange to be welded and the pipe to be welded is kept fixed, and the position of the other can be adjusted arbitrarily, so that the flange welding surface and the pipe welding surface can be accurately butted, without the need to adjust the positions of both the flange to be welded and the pipe to be welded arbitrarily.

[0044] Therefore, the flange lifting assembly 1 in this embodiment is fixed to the support base plate 3 by means of threaded connection, and the base 20 of the pipe lifting assembly 2 is installed at any position on the support base plate 3 by magnetic attraction. That is, in the pipe structure welding auxiliary tooling provided in this embodiment, the position of the flange lifting assembly 1 is fixed, and the position of the pipe lifting assembly 2 on the support base plate 3 can be adjusted arbitrarily.

[0045] After connecting the flange to be welded to the flange lifting assembly 1 and making the welding surface of the flange perpendicular to the support base plate 3, the base 20 in the pipe lifting assembly 2 is fixed to the support base plate 3 by magnetic attraction. At the same time, according to the designed trend of the pipe to be welded, the spatial positions of the plurality of support members 21 are respectively adjusted by using a plurality of position adjustment structures 22 until the plurality of support members 21 are distributed in sequence along the designed trend of the pipe.

[0046] Then the pipe to be welded can be connected to the plurality of support members 21 in sequence. At the same time, the welding surface of the pipe to be welded also needs to be perpendicular to the support base plate 3. If the welding surface of the pipe to be welded is butted against the welding surface of the flange to be welded at this time, there is no need to adjust the position of the base 20 of the pipe lifting assembly 2; if there is a gap between the welding surface of the pipe to be welded and the welding surface of the flange to be welded at this time, the position of the base 20 in the pipe lifting assembly 2 can be moved on the support base plate 3 until the pipe welding surface is butted against the flange welding surface.

[0047] It should be noted that since the base 20 is fixed to the support base plate 3 by magnetic attraction, the position of the base 20 can be arbitrarily adjusted on the support base plate 3 and can be fixed after adjustment. Thus, after the pipeline welding surface and the flange welding surface are butted, they can remain in the butted state, facilitating the subsequent welding operation.

[0048] When using this tooling for welding operations on pipeline structures of different models, since the tooling can adjust the spatial position of the support member 21 through the position adjustment structure 22 so that the distribution position of the support member 21 conforms to the pipeline design trend in the pipeline structure, and the position of the base 20 on the support base plate 3 can be arbitrarily adjusted so that the pipeline welding surface in the pipeline structure can be butted with the flange welding surface, this tooling can be applied to welding operations on pipeline structures of different models. During the welding process, only the positions of the support member 21 and the base 20 need to be debugged, and there is no need to set up different pipeline structure welding auxiliary devices for different models of pipeline structures, effectively reducing the manufacturing cost.

[0049] Moreover, the pipeline lifting assembly 2 in this pipeline structure welding auxiliary tooling is fixed to the support base plate 3 by magnetic attraction and does not need to be inserted into the support base plate 3. Therefore, there is no need to precisely drill holes in the support base plate 3, which also effectively reduces the manufacturing cost of the tooling.

[0050] In addition, in the pipeline structure welding auxiliary tooling provided in this embodiment, whether it is the flange lifting assembly 1 or the pipeline lifting assembly 2, they are both detachably connected to the support base plate 3. Therefore, when transferring this pipeline structure welding auxiliary tooling, the structure of the tooling can be disassembled first and then moved separately, rather than moving the whole tooling, thus effectively improving the convenience of use for the operator.

[0051] It should be noted that when debugging the positions of the base 20 and the support member 21 in this pipeline structure welding auxiliary tooling according to different models of pipeline structures, the positions of the base 20 and multiple support members 21 can be calibrated and determined based on a standard pipeline structure that has been welded and passed the welding inspection. Specifically, first, judge how many lifting support points are needed for the pipeline according to the weight and center of gravity of the pipeline in the pipeline structure and the approximate position of the pipeline in space, and then select multiple pipeline lifting assemblies 2 correspondingly based on the judgment result. Place the base 20 in the pipeline lifting assembly 2 on the support base plate 3 based on the approximate position of the pipeline in space. Then, the flange in the standard pipeline structure that has been welded and passed the welding inspection can be fixed to the flange lifting assembly 1, and then the positions of the base 20 and multiple support members 21 can be adjusted correspondingly based on the pipeline position and trend in the standard pipeline structure at this time. After the standard pipeline structure is disassembled from this tooling, the tooling debugging is completed, and at this time, the tooling can be applied to the welding operations of all pipelines of the same model as the standard pipeline structure.

[0052] Compared with the prior art, the welding auxiliary tool for the pipeline structure provided in this embodiment connects the base 20 and the support bottom plate 3 in a magnetic attraction manner, and the spatial position of the support member 21 can be flexibly adjusted through the position adjustment structure 22, so that the pipeline lifting assembly 2 can be adapted to different types of pipeline structures. As a result, this tool is applicable to different types of pipeline structures, eliminating the need to manufacture different specifications of tools according to different types of pipeline structures, effectively reducing the manufacturing cost of the tool. At the same time, the magnetic attraction method enables the pipeline lifting assembly 2 to be stably fixed on the support bottom plate 3, eliminating the need to insert and weld the pipeline lifting assembly 2 to the support bottom plate 3. Correspondingly, there is no need to precisely drill holes on the support bottom plate 3, further effectively reducing the manufacturing cost. In addition, this welding auxiliary tool for the pipeline structure connects the flange lifting assembly 1 and the support bottom plate 3 by threaded connection, and connects the pipeline lifting assembly 2 and the support bottom plate 3 by magnetic attraction, enabling the overall tool to be disassembled, thus facilitating the separate movement of each structure of the tool when transferring the tool, effectively improving the convenience of movement for the operator.

[0053] In practical applications, the position adjustment structure 22 can adopt a three-coordinate (the three coordinates refer to the coordinates in the three directions of space X, Y, and Z) moving platform.

[0054] To simplify the structure of the position adjustment structure 22 and reduce its usage cost, as Figure 2 shown, this embodiment preferably includes a ball hinge 220 and a ball hinge 220 fixing member in the position adjustment structure 22; the ball hinge 220 is connected between the support member 21 and the base 20, and the ball hinge 220 is used to drive the support member 21 to rotate relative to the base 20 to adjust the relative angle between the support member 21 and the support bottom plate 3; the ball hinge 220 fixing member is used to connect with the rotated ball hinge 220 to limit the continuous rotation of the ball hinge 220.

[0055] Among them, the ball hinge 220 can drive the support member 21 to rotate relative to the base 20 through its own rotation, changing the relative angle between the support member 21 and the support bottom plate 3, thereby realizing the position adjustment of the support member 21 in three-dimensional space.

[0056] The ball hinge 220 fixing member is used to limit the continuous rotation of the ball hinge 220 after the ball hinge 220 drives the support member 21 to rotate, thereby ensuring the position stability of the support member 21 after position adjustment.

[0057] Further, as Figure 2 shown, the ball hinge 220 includes a ball seat 2200, a ball 2201, and a ball rod 2202; a ball hole for accommodating the ball 2201 is provided inside the ball seat 2200, and a through hole communicating with the ball hole is provided on the side wall of the ball seat 2200. The ball 2201 is rotatably installed in the ball hole, one end of the ball rod 2202 passes through the through hole and is connected to the ball 2201, and the other end is located outside the ball hole; the support member 21 is detachably connected to the ball rod 2202.

[0058] During the process of the ball joint 220 driving the support member 21 to rotate, the sphere 2201 in the ball joint 220 can rotate within the ball hole of the ball seat 2200, and at the same time drive the ball rod 2202 connected thereto to rotate in three-dimensional space. Since the ball rod 2202 is connected to the support member 21, when the ball rod 2202 rotates, it can drive the support member 21 to rotate, thereby changing the relative angle between the support member 21 and the support base plate 3.

[0059] It should be noted that the detachable connection between the support member 21 and the ball rod 2202 can improve the convenience of installation and disassembly of the support member 21, so as to facilitate replacing the support member 21 with a corresponding specification according to the model of the pipeline structure, and to facilitate replacing a new support member 21 when the support member 21 is damaged due to welding operations.

[0060] Furthermore, the support member 21 and the ball rod 2202 are detachably connected by a threaded connection method.

[0061] Specifically, as Figure 3 shown, the support member 21 can be provided with a countersunk hole 210, as Figure 2 shown, the ball rod 2202 is provided with a mounting hole 22020; the countersunk hole 210 and the mounting hole 22020 are used to communicate correspondingly when the ball rod 2202 abuts against one side of the support member 21. A bolt-nut structure is inserted into the communicated countersunk hole 210 and mounting hole 22020, and this bolt-nut structure is used to fixedly connect the ball rod 2202 and the support member 21.

[0062] In this embodiment, the fixing member of the sphere 2201 is a bolt. As Figure 2 shown, the side wall of the ball seat 2200 is also provided with a first threaded hole 22000 communicating with the ball hole. The fixing member of the sphere 2201 is threadedly connected into the first threaded hole 22000 and can abut against the sphere 2201.

[0063] After adjusting the position of the support member 21 in place by using the sphere 2201 and the ball rod 2202, the fixing member of the sphere 2201 can be threadedly connected into the first threaded hole 22000, and the end of the fixing member of the sphere 2201 located inside the ball seat 2200 abuts against the side wall of the sphere 2201. At this time, by using the frictional force generated by the abutting relationship between the fixing member of the sphere 2201 and the sphere 2201, the sphere 2201 can be stably fixed in the ball hole, effectively restricting the sphere 2201 from continuing to rotate, achieving the effect of fixing the sphere 2201.

[0064] To maximize the fixing effect of the fixing member of the sphere 2201 on the sphere 2201, in this embodiment, it is preferably that the center of the sphere 2201 is located on the central axis of the first threaded hole 22000.

[0065] AsFigure 1 As shown, a vertical support rod 200 is fixed on the base 20. The position adjustment structure 22 further includes a slider 221. The ball hinge 220 is connected to the slider 221, and the slider 221 is slidably connected to the vertical support rod 200. The slider 221 can slide on the vertical support rod 200 and be fixedly connected to the vertical support rod 200 after sliding.

[0066] The vertical support rod 200 and the slider 221 can cooperate with each other to further adjust the vertical position of the ball hinge 220 and the support member 21, thereby further increasing the position adjustment range and adjustment flexibility of the support member 21, so that the pipeline lifting assembly 2 can be applied to more types of pipeline structures.

[0067] It should be noted that the position adjustment effect of the ball hinge 220 on the support member 21 can be regarded as fine adjustment. Compared with the ball hinge 220, the vertical support rod 200 and the slider 221 cooperate with each other to have a wider vertical position adjustment range of the support member 21. When adjusting the position of the support member 21 by using the position adjustment structure 22, the slider 221 can be first slid on the vertical support rod 200 to achieve rough adjustment of the vertical position of the support member 21, and then the ball hinge 220 can be rotated to achieve fine adjustment of the position of the support member 21.

[0068] It can be seen that the position adjustment range of the ball hinge 220 for the support member 21 is limited. Therefore, in this embodiment, it is preferably that a vertical support rod 200 is fixed on the base 20, the position adjustment structure 22 further includes a slider 221, and the slider 221 is slidably connected to the vertical support rod 200.

[0069] Among them, the fixed connection between the slider 221 and the vertical support rod 200 after the slider 221 slides on the vertical support rod 200 can be realized by magnetic attraction, clamping, bolt connection or pin connection. There is no limitation on the fixed connection method between the slider 221 and the vertical support rod 200, as long as the position fixation of the slider 221 after sliding can be achieved.

[0070] As Figure 1 shown, a horizontal support rod 222 is provided between the ball hinge 220 and the slider 221. The horizontal support rod 222 is horizontally distributed, and the ball hinge 220 is detachably connected to the horizontal support rod 222, and the slider 221 is slidably connected to the horizontal support rod 222. The slider 221 can slide relative to the horizontal support rod 222 and be fixedly connected to the horizontal support rod 222 after relative sliding.

[0071] When it is necessary to adjust the horizontal position of the support member 21, the horizontal support rod 222 can also be slid on the slider 221, so that the horizontal support rod 222 drives the ball hinge 220 connected thereto to move synchronously. After the ball hinge 220 moves, it can drive the support member 21 connected thereto to move, thereby realizing the adjustment of the horizontal position of the support rod.

[0072] It can be seen that the horizontal support rod 222 and the slider 221 can cooperate with each other to further adjust the horizontal position of the support member 21. Similarly, the position adjustment range and flexibility of the support member 21 can be further improved, so that the pipeline lifting assembly 2 can be applied to more types of pipeline structures.

[0073] In addition, compared with the horizontal position adjustment effect of the ball hinge 220 on the support member 21, the horizontal support rod 222 and the slider 221 cooperate with each other to have a wider horizontal position adjustment range of the support member 21. When adjusting the position of the support member 21 by using the position adjustment structure 22, the horizontal support rod 222 can be slid on the slider 221 to achieve a rough adjustment of the horizontal position of the support member 21, and then the ball hinge 220 can be rotated to achieve a fine adjustment of the position of the support member 21.

[0074] In this embodiment, the fixed connection between the horizontal support rod 222 and the slider 221 after the horizontal support rod 222 slides on the slider 221 can also be realized by magnetic attraction, clamping, bolt connection or pin connection. There is no limitation on the fixed connection method between the horizontal support rod 222 and the slider 221, as long as the position fixation after the horizontal support rod 222 slides can be achieved.

[0075] It should also be noted that the ball hinge 220 and the horizontal support rod 222 in this embodiment are detachably connected. The detachable connection method can improve the convenience of installation and disassembly of the ball hinge 220 on the horizontal support rod 222.

[0076] Furthermore, the ball hinge 220 and the horizontal support rod 222 can be detachably connected by a threaded connection method. Specifically, as Figure 2 shown, a horizontal threaded hole 2203 is provided on the side of the ball hinge 220 close to the horizontal support rod 222, and an external thread adapted to the horizontal threaded hole 2203 is provided on the rod body of the horizontal support rod 222 close to the ball hinge 220. The horizontal support rod 222 is threadedly connected into the horizontal threaded hole 2203 through the external thread thereon.

[0077] When the ball hinge 220 includes a sphere 2201, a ball rod 2202 and a ball seat 2200, the horizontal threaded hole 2203 can be provided on the side of the ball seat 2200 away from the ball rod 2202.

[0078] To improve the threaded connection convenience between the ball seat 2200 and the horizontal support rod 222, as Figure 2As shown, the shape of the radial cross-section of the ball seat 2200 can be the same as that of the kidney-shaped hole, or the outer peripheral wall of the ball seat 2200 can be prism-shaped. When the radial cross-section of the ball seat 2200 is the same as the shape of the kidney-shaped hole or the outer peripheral wall of the ball seat 2200 is prism-shaped, a flat portion can be formed on the outer peripheral wall of the ball seat 2200, which facilitates the tool to clamp and turn the ball seat 2200, thereby facilitating the threaded connection of the ball seat 2200 to the horizontal support rod 222.

[0079] In addition, a chamfer can be provided at the edge of the end of the horizontal support rod 222 near its external thread, and this chamfer is used to improve the convenience of the horizontal support rod 222 entering the horizontal threaded hole 2203, and can also improve the threaded connection convenience between the ball seat 2200 and the horizontal support rod 222.

[0080] It should be noted that in the multiple position adjustment structures 22 provided in this embodiment, the positions of the horizontal support rods 222 and the vertical support rods 200 of each position adjustment structure 22 can be different. At this time, the positions of the multiple support members 21 in space are also different, and they can be flexibly distributed in sequence along the pipeline design direction.

[0081] In this embodiment, the slider 221 is provided with a vertical sliding hole and a horizontal sliding hole. The vertical support rod 200 passes through the vertical sliding hole, and the horizontal support rod 222 passes through the horizontal sliding hole; the side wall of the slider 221 is provided with a second threaded hole and a third threaded hole. The second threaded hole extends along the radial direction of the horizontal sliding hole and is communicated with the horizontal sliding hole, and the third threaded hole extends along the radial direction of the vertical sliding hole and is communicated with the vertical sliding hole; the position adjustment structure 22 further includes a vertical fixing bolt 223 and a horizontal fixing bolt 224. The horizontal fixing bolt 224 is threadedly connected to the second threaded hole and can abut against the horizontal support rod 222, and the vertical fixing bolt 223 is threadedly connected to the third threaded hole and can abut against the vertical support rod 200.

[0082] The vertical sliding hole is used to realize the sliding connection between the slider 221 and the vertical support rod 200, and the horizontal sliding hole is used to realize the sliding connection between the slider 221 and the horizontal support rod 222.

[0083] It should be noted that when the slider 221 is slidably connected to the vertical support rod 200 through the vertical sliding hole, not only can the vertical position adjustment of the slider 221 be realized, but also the slider 221 can be rotated with the vertical support rod 200 as the rotation axis, so as to realize the angle adjustment of the slider 221, further expanding the position adjustment range and position adjustment flexibility of the support member 21.

[0084] Correspondingly, when the slider 221 is slidably connected to the horizontal support rod 222 through a horizontal sliding hole, not only can the horizontal position of the horizontal support rod 222 be adjusted, but also the horizontal support rod 222 can rotate about its own central axis, so as to realize the angle adjustment of the ball hinge 220 and the support member 21, further expanding the position adjustment range and position adjustment flexibility of the support member 21.

[0085] After the position adjustment process of the horizontal support rod 222 on the slider 221 is completed, the horizontal fixing bolt 224 can be threadedly connected to the second threaded hole, and the end of the horizontal fixing bolt 224 located inside the slider 221 abuts against one side of the rod body of the horizontal support rod 222, so as to limit the horizontal support rod 222 from continuing to slide inside the slider 221 and achieve the limit fixing effect on the horizontal support rod 222.

[0086] Correspondingly, after the position adjustment process of the slider 221 on the vertical support rod 200 is completed, the vertical fixing bolt 223 can be threadedly connected to the third threaded hole, and the end of the vertical fixing bolt 223 located inside the slider 221 abuts against one side of the rod body of the vertical support rod 200, so as to limit the slider 221 from continuing to slide on the vertical support rod 200 and achieve the limit fixing effect on the slider 221.

[0087] In this embodiment, one of the base 20 and the support base plate 3 can be selected as a permanent magnet, and the other is selected as a magnetic metal or alloy. At this time, placing the base 20 on the support base plate 3 can make the base 20 and the support base plate 3 magnetically attract each other by the magnetic attraction of the permanent magnet.

[0088] Alternatively, the base 20 can be a switch-type magnetic base, and the support base plate 3 is selected as a magnetic metal or alloy. An electromagnet generating device is provided inside the base 20, and a switch for controlling the energization or power-off of the electromagnet generating device is provided on the base 20. During the process of adjusting the position of the base 20 on the support base plate 3, the switch can be disconnected. At this time, the electromagnet generating device stops working and will not generate a magnetic field at the base 20, and there will be no magnetic attraction between the base 20 and the support base plate 3. After adjusting the position of the base 20 on the support base plate 3, the switch is closed again. At this time, the electromagnet generating device works, generating a magnetic field at the base 20, so as to adsorb and fix the base 20 on the support base plate 3.

[0089] In this embodiment, to improve the disassembly and assembly convenience of the vertical support rod 200, the vertical support rod 200 and the base 20 can also be detachably connected.

[0090] Specifically, the base 20 can be provided with a threaded hole, and an external thread is provided on the rod body of the vertical support rod 200 close to the base 20. The vertical support rod 200 is threadedly connected to the threaded hole on the base 20 through the external thread on it.

[0091] In order to improve the convenience of the threaded connection between the vertical support rod 200 and the base 20 , the edge of the end of the vertical support rod 200 close to the base 20 may also be chamfered.

[0092] It should be noted that the flange in the pipeline structure is usually tubular and a ring plate is provided at the edge of the end of the flange away from the pipeline, and the ring plate is used to abut against the flange ring plate in other pipeline structures. In order to achieve the fixed connection between the two ring plates, the ring plate is usually also provided with a plurality of bolt holes distributed along the circumference thereof. After the two ring plates are abutted, the bolt holes thereon are connected one by one, and can be used to install bolts to fix the two ring plates.

[0093] Based on the structure of the flange in the pipeline structure, such as Figure 1 As shown, the flange lifting assembly 1 of the present embodiment preferably includes a first limit member 10 and a second limit member 11; the bottom end of the first limit member 10 and the bottom end of the second limit member 11 are respectively fixed to the supporting base plate 3 by bolts; the top end of the first limit member 10 is provided with a first limit protrusion 100, and the top end of the second limit member 11 is provided with a second limit protrusion 110, the first limit protrusion 100 is used to be inserted into the bolt hole on the flange to be welded, and the second limit protrusion 110 is used to be inserted into the docking hole at the center of the flange to be welded.

[0094] After the first stopper 10 and the second stopper 11 are fixed to the support base plate 3 by bolt connection, the position stability of the flange can be ensured by supporting and limiting the flange by the first stopper 10 and the second stopper 11. Therefore, the top of the first stopper 10 and the top of the second stopper 11 in this embodiment are respectively provided with stopper protrusions, and the first stopper protrusion 100 is inserted into the bolt hole on the flange, and the second stopper protrusion 110 is inserted into the docking hole at the center of the flange (that is, the inner space of the flange).

[0095] It should be noted that the flange in the pipeline structure of the air-conditioning pipe is usually in the shape of a curved pipe and is approximately L-shaped or L-shaped. At this time, in order to ensure that the welding surface of the flange is perpendicular to the supporting base plate 3, the first limit member 10 and the second limit member 11 can both be columnar, and the first limit member 10 and the second limit member 11 can both be erected on the supporting base plate 3.

[0096] If the flange in the pipeline structure is in the shape of a straight tube or an irregular shape, the shape or position of the first limit member 10 and the second limit member 11 can be adjusted accordingly according to the position of the flange welding surface so that the welding surface of the flange inserted on the first limit protrusion 100 and the second limit protrusion 110 remains perpendicular to the supporting base plate 3.

[0097] To improve the insertion convenience between the first limiting protrusion 100 and the bolt holes of the flange, in this embodiment, it is preferred that a chamfer is provided at the end edge of the first limiting protrusion 100 away from the first limiting member 10. Correspondingly, to improve the insertion convenience between the second limiting protrusion 110 and the docking holes of the flange, in this embodiment, it is preferred that a chamfer is provided at the end edge of the second limiting protrusion 110 away from the second limiting member 11.

[0098] In this embodiment, threaded holes may be respectively provided at the bottom ends of the first limiting member 10 and the second limiting member 11. Two through holes are provided on the support base plate 3. One through hole is used to communicate with the threaded hole at the bottom end of the first limiting member 10 correspondingly, and a first bolt is inserted through the correspondingly communicated through hole and threaded hole; the other through hole is used to communicate with the threaded hole at the bottom end of the second limiting member 11 correspondingly, and a second bolt is inserted through the correspondingly communicated through hole and threaded hole. The first bolt is used to realize the fixed connection between the first limiting member 10 and the support base plate 3, and the second bolt is used to realize the fixed connection between the second limiting member 11 and the support base plate 3.

[0099] As Figure 3 shown, a limiting groove 211 is provided at the top of each support member 21. The limiting groove 211 is used to accommodate the pipeline to be welded, and a chamfer is provided between the notch of the limiting groove 211 and the inner side wall of the groove.

[0100] When multiple support members 21 are distributed in sequence along the design direction of the pipeline, the limiting grooves 211 on each support member 21 all extend along the design direction of the pipeline. Placing the pipeline to be welded in the limiting grooves 211 on multiple support members 21 can ensure the stability of the pipeline on the pipeline lifting assembly 2.

[0101] Among them, the limiting groove 211 can play a role in limiting the pipeline to be welded, thereby improving the stability of the pipeline on the support member 21.

[0102] And a chamfer is provided between the notch of the limiting groove 211 and the inner side wall of the groove, which can improve the convenience of the pipeline entering the limiting groove 211 and the convenience for the operator to take out the pipeline from the limiting groove 211.

[0103] Since the pipeline structure welding auxiliary tooling provided in this embodiment is used for the welding operation of the pipeline structure, in order to extend the service life of the tooling, in this embodiment, it is preferred that both the support base plate 3 and the flange lifting assembly 1 are made of burn-resistant materials.

[0104] Although the support member 21 and the local position adjustment structure 22 in this tooling will also be in the high-temperature environment during the welding operation, since both the support member 21 and the position adjustment structure 22 are easy to disassemble, the materials of the support member 21 and the position adjustment structure 22 can be made of inexpensive non-fire-resistant materials. When the support member 21 and the position adjustment structure 22 are worn out, the support member 21 and the position adjustment structure 22 can be directly replaced.

[0105] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
