Description

Technical Field

[0001] This utility model relates to the field of welding device technology, specifically a temporary welding device for building construction with a magnetic positioning bracket. Background Technology

[0002] In the construction industry, temporary welding is a common technique for on-site component connection, component repair, and temporary facility construction. Existing temporary welding equipment for construction is mainly used for welding and localized thermal cutting of various metal components on construction sites. The operation involves the application of brazing or welding processes, and can also be used to perform localized heating cutting operations such as flame cutting. Some equipment can also be adapted to laser beam processing and other process requirements to meet the diverse needs of temporary connection, repair, and component handling on construction sites.

[0003] To address the need for 360° circumferential welding in carbon steel pipe welding operations, while existing magnetic positioning technology can achieve initial positioning of the carbon steel pipe, the magnetic base and the curved surface of the carbon steel pipe are in rigid line contact during the circumferential rotation welding process. This results in significant sliding friction during rotation, causing scratches and damage to the outer wall of the carbon steel pipe. This not only damages the oxide protective film or galvanized layer on the surface of the carbon steel pipe, but also easily forms stress concentration points at the scratches, reducing the corrosion resistance of the carbon steel pipe. Therefore, a temporary welding device for building construction with a magnetic positioning bracket is proposed to address the above problems. Utility Model Content

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figures 1-8 This utility model provides a technical solution:

[0030] A temporary welding device for building construction with a magnetic positioning bracket includes a temporary welding device body 1. One end of the temporary welding device body 1 is fixedly connected to an operating table assembly 2. The upper end of the operating table assembly 2 is fixedly connected to a load-bearing component 3 and a telescopic pushing component 4. The operating table assembly 2 includes a base plate 21. A guide shell 22 is fixedly connected to the top of the base plate 21. A guide groove 23 and a first through-hole 24 are opened on the inner side of the guide shell 22. A guide block 25 is slidably connected to the inner side of the guide groove 23. A permanent magnet block 26 is fixedly connected to the inner side of the guide block 25. An assembly plate 28 is fixedly connected to one side of the guide groove 23. A permanent magnet plate 27 is fixedly connected to one side of the assembly plate 28 by bolts. The load-bearing component 3 includes a support plate 31. A bearing seat 32 is fixedly connected to the top of the support plate 31. A shaft column 33 is rotatably connected to the inner side of the bearing seat 32. A magnetic column 34 and a support column 35 are fixedly connected to the outer side of the shaft column 33. The lower end of the magnetic column 34 meshes with a toothed groove 36 opened in the carbon steel plate 37.

[0031] As a further implementation of this solution, the bottom end of the substrate 21 is fixedly connected to the table surface of the temporary welding device body 1, and the top end of the guide shell 22 is fixedly connected to the support plate 31 and the bearing seat 32. Through the above-mentioned arrangement, this connection method can ensure the stability of the installation of the substrate 21, the support plate 31 and the bearing seat 32, provide a stable support foundation for the placement and load-bearing of the carbon steel pipe and subsequent rotation welding, avoid the steel pipe positioning displacement caused by component loosening during the welding process, and ensure welding accuracy and operational safety.

[0032] As a further implementation of this solution, a groove is provided on the upper end of the substrate 21, and a slider is fixedly connected to the bottom end of the permanent magnet plate 27. The slider of the permanent magnet plate 27 slides inside the groove of the substrate 21. A handle 29 is fixedly connected to the right side of the assembly plate 28 and extends to the front end of the substrate 21. Through the above settings, the cooperation between the groove and the slider can accurately control the sliding trajectory and range of the permanent magnet plate 27, ensuring that the permanent magnet plate 27 can accurately align and cooperate with other structures when it drives the related components to move. At the same time, the design of the handle 29 extending to the front end of the substrate 21 facilitates manual operation by the operator, improves the convenience of operation, helps to quickly switch the positioning and welding states, and improves work efficiency.

[0033] As a further implementation of this solution, the guide groove 23 is connected to the first port 24, which is located at the upper end of the guide groove 23. The first port 24 is aligned vertically with the permanent magnet block 26, and the permanent magnet block 26 is magnetically attracted to the carbon steel plate 37. Through the above arrangement, the connection between the guide groove 23 and the first port 24 ensures the rationality of the installation layout of the relevant structure. The vertical alignment of the first port 24 and the permanent magnet block 26, combined with their magnetic attraction characteristics, ensures that after pulling the handle 29, the permanent magnet block 26 can accurately generate a magnetic attraction force with the carbon steel plate 37, thereby reliably driving the carbon steel plate 37 to move downward to achieve engagement and disengagement, ensuring the smooth progress of circumferential rotation welding of the carbon steel pipe, and avoiding damage to the steel pipe caused by sliding friction.

[0034] As a further implementation of this solution, a second opening 38 is provided on the inner side of the support plate 31. The second opening 38 is aligned vertically with the first opening 24. Through the above-mentioned arrangement, the vertical alignment of the second opening 38 with the first opening 24 ensures that the permanent magnet block 26 is accurately positioned during the magnetic attraction process, avoids the failure of magnetic attraction with the carbon steel plate 37 due to the displacement of the permanent magnet block 26, ensures the stable triggering of the engagement and disengagement mechanism, and further improves the smoothness of the rotation welding of the carbon steel pipe.

[0035] As a further implementation of this solution, the telescopic push assembly 4 includes a cylindrical shell 41. A guide post 42 is slidably connected to the inner side of the cylindrical shell 41. A rubber sealing ring 43 is fixedly connected to the outer side of the guide post 42. A spring 44 is fixedly connected to the bottom end of the guide post 42. The outer side of the rubber sealing ring 43 fits against the inner side of the cylindrical shell 41. The cylindrical shell 41 is fixedly connected to the inner side of the support plate 31. An insertion port 45 is opened at the lower end of the cylindrical shell 41. A duckbill valve 46 is fixedly connected to the inner side of the insertion port 45. A slow-flow hole 47 is opened near the upper part of the duckbill valve 46. A protective cylinder is fixedly connected to the inner side of the cylindrical shell 41. 48. The protective cylinder 48 is located at the upper end of the mounting port 45. Through the above-mentioned arrangement, the mounting port 45 provides a stable installation space for the duckbill valve 46. The cooperation between the duckbill valve 46 and the slow flow hole 47 can realize the slow flow of gas inside the cylinder shell 41, which can effectively reduce the rapid downward displacement of the guide post 42 caused by external vibration, thereby preventing the failure of the tooth groove 36 and the magnetic post 34 to mesh due to the rapid downward movement of the carbon steel plate 37. At the same time, the protective cylinder 48 can limit the sliding stroke of the guide post 42, avoid the guide post 42 from moving too far downward and damaging the components, and ensure the stability of the carbon steel pipe welding process.

[0036] Workflow: In use, place the carbon steel pipe on the outer surface of the two support columns 35 on the upper end of the base plate 21. Since the support columns 35 have a long span, the carbon steel pipe can achieve stable load-bearing through the two support columns 35. At the same time, the axis of the carbon steel pipe is aligned vertically with the middle of the two support columns 35. The left and right ends of the operating table assembly 2, load-bearing assembly 3, and telescopic push assembly 4 are aligned left and right respectively. Then, place the end of another carbon steel pipe against the end of the previously placed carbon steel pipe and place it on the outer surface of the two support columns 35 on the upper end of another base plate 21. At this time, the axes of the two carbon steel pipes are aligned left and right, and the two carbon steel pipes are magnetically positioned by the corresponding permanent magnet plates 27. Through the magnetic attraction, the carbon steel pipe is tightly attached to the outer surface of the support column 35. Under the action of friction between the carbon steel pipe and the support column 35, and at the same time, the telescopic push assembly 4 pushes the toothed groove 36 of the carbon steel plate 37 to mesh with the magnetic column 34, which achieves the effect of positioning the two carbon steel pipes. At this time, the two carbon steel pipes can be welded together by the temporary welding device body 1.

[0037] During the 360° circumferential welding of the carbon steel pipe, the assembly plate 28 is moved by pulling the handle 29. The assembly plate 28 drives the permanent magnet plate 27 and the guide block 25 to move to the right simultaneously. The slider of the permanent magnet plate 27 slides in the groove at the upper end of the base plate 21. The groove on the base plate 21 can control the sliding position of the permanent magnet plate 27. When the permanent magnet block 26 is aligned vertically with the first through-hole 24, the handle 29 can no longer be pulled. The magnetic attraction between the permanent magnet block 26 and the carbon steel plate 37 can overcome the downward movement of the guide post 42. The resistance and elastic force of the spring 44, through the magnetic attraction between the permanent magnet block 26 and the support plate 31, cause the carbon steel plate 37 to move downward, eventually causing the toothed groove 36 of the carbon steel plate 37 to move away from the magnetic column 34, while not affecting the continuous magnetic attraction of the permanent magnet plate 27 to the steel pipe. Then, by manually rotating the carbon steel pipe, the friction between the carbon steel pipe and the support column 35 will drive the support column 35, the magnetic column 34 and the shaft column 33 to rotate simultaneously. The shaft column 33 rotates inside the shaft seat 32, thereby performing temporary welding work on the carbon steel pipe in a 360° circumferential direction.

[0038] During the welding process, to prevent the carbon steel pipe from rotating on its own, in accordance with the above principle, when the guide post 42 moves downward under the pressure of the carbon steel plate 37, the guide post 42 presses against the spring 44. The rubber sealing ring 43 seals the cylinder shell 41 and the guide post 42. At this time, the gas inside the cylinder shell 41 will enter the duckbill valve 46 through the slow flow hole 47 and then flow out through the duckbill valve 46. The duckbill valve 46 and the slow flow hole 47 can prevent the guide post 42 from moving downward rapidly due to external vibration, thereby preventing the rapid downward movement of the carbon steel plate 37 from causing the toothed groove 36 and the magnetic post 34 to fail to mesh, thus ensuring the stability of the carbon steel pipe welding.

[0039] Based on the above principles, when the device is used to weld carbon steel pipes in a 360° circumferential direction, it can prevent significant sliding friction from occurring when the carbon steel pipe rotates, reduce scratch damage to the outer wall of the steel pipe that could damage the oxide protective film or galvanized layer on the surface of the carbon steel pipe, and thus ensure that the toughness and corrosion resistance of the carbon steel pipe after welding are not affected.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
