Description

Technical Field

[0001] This utility model relates to the field of water pipe welding, specifically to a welding device for large-diameter circulating water pipes. Background Technology

[0002] Water pipes need to be welded together, and a fixed support device is required during the welding process to support and fix the water pipes, preventing displacement or deformation during welding. However, existing welding devices have the fixing tools installed on the outer wall of the water pipe, creating obstacles during welding and hindering the welding work. Therefore, those skilled in the art have provided a welding device for large-diameter circulating water pipes to solve the problems mentioned in the background. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a welding device for large-diameter circulating water pipes, including a support plate, a central rod, a first support component, a second support component, a central support component, a radius adjustment plate, a first water pipe, a second water pipe, a base plate, a fixing plate, and an arc-shaped top plate. The base plate is installed at the bottom of the support plate, and the fixing plate is installed at the top of the support plate. The central rod is detachably installed between the fixing plates. Four first support components are installed at the left end of the central rod, four second support components are installed at the right end of the central rod, and four central support components are installed in the middle of the central rod. A radius adjustment plate is installed inside the first support component, the second support component, and the central support component. An arc-shaped top plate is installed on the top of the radius adjustment plate, and the arc-shaped top plate abuts against the inner wall of the first water pipe and the second water pipe.

[0004] Preferably, the first support member, the second support member, and the central support member are all provided with a moving groove, the left and right sides of the moving groove are provided with a sliding groove, and the front and rear sides of the moving groove are provided with a limiting groove.

[0005] Preferably, the left and right side plates of the limiting groove are provided with multiple No. 1 adjustment holes at equal intervals;

[0006] Preferably, the radius adjustment plate is provided with multiple second adjustment holes at equal intervals, and fixing bolts can be inserted into the first and second adjustment holes. A sliding plate is installed at the bottom of the right side wall of the radius adjustment plate. The sliding plate can move in the sliding groove. A lever is installed on the right side wall of the sliding plate.

[0007] Preferably, limiting plates are installed at the bottom of the front and rear side walls of the radius adjustment plate, and the limiting plates can move within the limiting groove.

[0008] The technical effects and advantages of this utility model are as follows:

[0009] 1. Adjust the radius adjustment plate according to the radius of the water pipe. The plate is positioned within the first support, second support, and center support. By moving the lever, the slide plate slides within the groove, allowing the radius adjustment plate to move within the moving groove. After the radius adjustment is completed, the fixing bolts are inserted into the first and second adjustment holes to prevent the radius adjustment plate from moving. The operation is simple and can adjust the radius length according to different sizes of water pipes, making it widely applicable.

[0010] 2. The arc-shaped top plate at the top of the radius adjustment plate can support the water pipes and act as an inner wall support, ensuring that the No. 1 and No. 2 water pipes can be welded stably without the need for fixing on the outer ring of the water pipes. This eliminates the presence of external obstructions during the welding process and improves work efficiency. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose. Example

[0019] Please see Figures 1-6 In this embodiment, a welding device for large-diameter circulating water pipes is provided, including a support plate 1, a central rod 2, a first support component 3, a second support component 4, a central support component 5, a radius adjustment plate 6, a first water pipe 8, a second water pipe 9, a base plate 101, a fixing plate 102, and an arc-shaped top plate 601. The base plate 101 is installed at the bottom of the support plate 1, and the fixing plate 102 is installed at the top of the support plate 1. The central rod 2 is detachably installed between the fixing plates 102. Four first support components 3 are installed at the left end of the central rod 2, four second support components 4 are installed at the right end of the central rod 2, and four central support components 5 are installed in the middle of the central rod 2. The radius adjustment plate 6 is installed inside the first support component 3, the second support component 4, and the central support component 5. The arc-shaped top plate 601 is installed on the top of the radius adjustment plate 6, and the arc-shaped top plate 601 abuts against the inner wall of the first water pipe 8 and the second water pipe 9.

[0020] Specifically, the first support member 3, the second support member 4 and the central support member 5 are all provided with a moving groove 501. The left and right sides of the moving groove 501 are provided with a sliding groove 502. The front and rear sides of the moving groove 501 are provided with a limiting groove 503. The left and right side plates of the limiting groove 503 are provided with multiple first adjustment holes 504 at equal intervals.

[0021] Multiple No. 2 adjustment holes 602 are provided at equal intervals on the radius adjustment plate 6. Fixing bolts 7 can be inserted into the No. 1 adjustment hole 504 and the No. 2 adjustment hole 602.

[0022] A sliding plate 603 is installed at the bottom of the right side wall of the radius adjustment plate 6. The sliding plate 603 can move within the slide groove 502. A lever 604 is installed on the right side wall of the sliding plate 603.

[0023] Limiting plates 605 are installed at the bottom of the front and rear side walls of the radius adjustment plate 6, and the limiting plates 605 can move within the limiting groove 503.

[0024] The working principle of this utility model is as follows:

[0025] When using a large-diameter circulating water pipe welding device, the radius adjustment plate 6 is positioned within the first support 3, the second support 4, and the central support 5 according to the radius of the water pipe. By moving the lever 604, the sliding plate 603 slides within the sliding groove 502, thereby allowing the radius adjustment plate 6 to move within the moving groove 501. After the radius adjustment is completed, the fixing bolts 7 are inserted into the first adjustment hole 504 and the second adjustment hole 602 to prevent the radius adjustment plate 6 from moving. This allows the arc-shaped top plate 601 at the top of the radius adjustment plate 6 to support the water pipe, providing inner wall support and ensuring stable welding of the first water pipe 8 and the second water pipe 9.

[0026] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
