Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 4 The present invention provides an embodiment of a spiral anchor bolt circumferential butt weld welding device, comprising a workbench 1, a welding assembly fixedly connected to the top of the workbench 1, two clamping assemblies provided on the top of the workbench 1, and a cleaning assembly provided on the top of the workbench 1.

[0033] The clamping assembly includes a support frame 12 and a motor 15. The bottom of the support frame 12 is fixedly connected to the top of the workbench 1. A rotating ring 3 is rotatably connected to the inner wall of the support frame 12. A pulley 14 is fixedly connected to the outer side of the rotating ring 3. The top of the motor 15 is fixedly connected to the top of the workbench 1. A pulley 26 is fixedly connected to the output end of the motor 15. A belt connects the pulley 26 and the pulley 14. Multiple rotating shafts 11 are rotatably connected to the outer side of the rotating ring 3. A clamping rod 10 is rotatably connected to the end of the rotating shaft 11 away from the rotating ring 3. A worm gear ring 9 is rotatably connected to the outer side of the rotating ring 3. Two fixing blocks 7 are fixedly connected to the outer side of the rotating ring 3. A worm 8 is rotatably connected inside the fixing blocks 7. The worm 8 is meshed with the worm gear ring 9. A housing ring 13 is fixedly connected to the outer side of the worm gear ring 9. A connecting block 12 is provided between the housing ring 13 and the worm gear ring 9.

[0034] Specifically, the workbench 1 provides a support platform for the entire welding device. The welding assembly is used to weld the circumferential butt weld of the spiral anchor rod. The support frame 2 supports the rotating ring 3. The motor 5 drives the pulley 6 to output power. The rotating ring 3 drives the clamping rod 10 and other components to rotate, thereby clamping and rotating the anchor rod. The pulley 4 and pulley 6 are connected by a belt to transmit the power of the motor 5. The rotating shaft 11 enables the clamping rod 10 to rotate flexibly. The clamping rod 10 is used to clamp the spiral anchor rod. The worm gear ring 9 and the worm 8 mesh to achieve fine adjustment of the position of the clamping rod 10. The fixing block 7 is used to install the worm 8. The outer shell ring 13 and the connecting block 12 transmit the rotation of the worm gear ring 9 to push the clamping rod 10. The cleaning assembly is used to clean the weld of the spiral anchor rod and surrounding debris.

[0035] Reference Figure 1 - Figure 3The cleaning assembly includes an electric telescopic rod 17, which is fixedly connected to the top of the workbench 1 on its outer side. A movable plate 14 is fixedly connected to the output end of the electric telescopic rod 17. A brush cylinder 18 is rotatably connected inside the movable plate 14. A gear ring 19 is fixedly connected to the outer side of the brush cylinder 18. A motor 20 is fixedly connected to the outer side of the movable plate 14. A gear 21 is fixedly connected to the output end of the motor 20. The gear ring 19 and the gear 21 are meshed together.

[0036] Specifically, the electric telescopic rod 17 is used to drive the moving plate 14 to move vertically, bringing it closer to or away from the spiral anchor rod for cleaning operations. The moving plate 14, as a load-bearing component, provides an installation position for the brush cylinder 18, motor 20, etc., and, driven by the electric telescopic rod 17, moves the brush cylinder 18 and other components to a suitable cleaning position. The brush cylinder 18 is used to clean the weld seam and surrounding area of ​​the spiral anchor rod, removing welding slag, debris, etc. generated during the welding process. The gear ring 19 engages with the gear 21 to transmit the rotational power of the motor 20 to the brush cylinder 18, causing the brush cylinder 18 to rotate and achieve the cleaning action. The motor 20 drives the gear 21 to rotate, providing a power source for the rotation of the brush cylinder 18. The gear 21, through meshing with the gear ring 19, transmits the rotational power of the motor 20 to the brush cylinder 18, causing the brush cylinder 18 to rotate.

[0037] Reference Figure 1 - Figure 3 The welding assembly includes two support frames 24. A linear module 15 is fixedly connected to the top of the support frame 24. Two electric telescopic rods 16 are installed at the bottom of the linear module 15. A welding box 22 is fixedly connected to the output end of the electric telescopic rods 16. A welding head 25 is provided at the bottom of the welding box 22.

[0038] Specifically, support frame 24 is used to support the linear module 15 and ensure its stability during operation. The linear module 15 is used to adjust the horizontal position of the welding box 22 so that the welding head 25 can be aligned with welds at different positions, improving the flexibility and adaptability of welding operations. The electric telescopic rod 16 is used to adjust the vertical position of the welding box 22. Through telescopic movement, the welding head 25 can be precisely moved closer to or away from the circumferential butt weld of the spiral anchor rod to adapt to welding requirements at different heights. The welding box 22 provides a place for the installation and protection of the welding head 25, which is used to weld the circumferential butt weld of the spiral anchor rod.

[0039] Reference Figure 1 - Figure 3The belt connects pulley 6 and pulley 4. One side of connecting block 12 is rotatably connected to the inside of outer ring 13, and the other side of connecting block 12 is rotatably connected to the outside of worm gear ring 9. The outside of clamping rod 10 is slidably connected to the inside of connecting block 12. Two slide grooves 23 are opened inside the worktable 1. The bottom of the moving plate 14 is slidably connected to the inner wall of the slide groove 23. Two support legs are fixedly connected to the bottom of the worktable 1.

[0040] Specifically, pulley 6 receives power from motor 5 and transmits it to pulley 4 via a belt. Pulley 4 receives the power from pulley 6, thereby driving the rotating ring 3 to rotate. Connecting block 12 transmits the rotation of outer ring 13 to worm gear ring 9 or other components while ensuring relative rotational flexibility. The other side is rotatably connected to the outside of worm gear ring 9 to transmit the rotation of worm gear ring 9 to outer ring 13, achieving linkage between the two and allowing a certain degree of rotational freedom to push clamping rod 10 for clamping operation. Clamping rod 10 is used to clamp the spiral anchor bolt. The clamping mechanism, achieved by the action of connecting block 12, secures the spiral anchor rod. The slide 23 provides a track for the sliding of the moving plate 14, ensuring the directional and stable movement of the moving plate 14 on the workbench 1. The moving plate 14 carries components such as the brush cylinder 18 in the cleaning assembly and moves along the slide 23 under the push of the electric telescopic rod 17, moving the brush cylinder 18 and other components to the appropriate cleaning position. The support legs support the entire welding device, ensuring its stability and balance during operation and preventing the device from tipping over or shaking due to its own weight or the force exerted during operation.

[0041] Working principle: In this welding device, the clamping component plays its role first. When it is necessary to fix the spiral anchor rod, the worm 8 is rotated. Because the worm 8 is meshed with the worm wheel ring 9, the worm wheel ring 9 will rotate. During the rotation of the worm wheel ring 9, the connecting block 12 drives the outer shell ring 13 to rotate synchronously. During this process, the connecting block 12 will push the clamping rod 10 to move along the rotating shaft 11 as the worm wheel ring 9 and the outer shell ring 13 rotate, thereby realizing the clamping and fixing of spiral anchor rods of different sizes.

[0042] Before welding, the cleaning components are put into use. The electric telescopic rod 17 is started, and its output end pushes the moving plate 14 to slide in the slide groove 23 opened inside the workbench 1, so that the moving plate 14 is close to the welded spiral anchor rod. Then, the motor 20 is started, and the gear 21 at the output end of the motor 20 rotates. Since the gear ring 19 is meshed with the gear 21, it drives the brush cylinder 18 to rotate inside the moving plate 14. The rotating brush cylinder 18 cleans the weld seam and the surrounding area of ​​the spiral anchor rod and removes debris.

[0043] During the welding stage, the welding assembly begins to work. The linear module 15 is installed on top of the two support frames 24, which can be adjusted laterally. When the welding position needs to be adjusted, the linear module 15 is activated, which drives the two electric telescopic rods 16 installed at the bottom to move laterally. The electric telescopic rods 16 can be extended or shortened to adjust the height of the welding box 22. The welding head 25 at the bottom of the welding box 22 can then perform welding operations on the circumferential butt weld of the spiral anchor rod.

[0044] As welding progresses, motor 5 is turned on, and the output of motor 5 drives pulley 6 to rotate. Since pulley 6 and pulley 4 are connected by a belt, pulley 4 will rotate accordingly, which in turn drives the rotating ring 3 to rotate on the inner wall of the support frame 2. When the rotating ring 3 rotates, the two spiral anchor rods are already connected due to the previous welding. At this time, the rotating ring 3 will drive the two spiral anchor rods and the clamping assembly to rotate simultaneously, thereby performing annular welding on both.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
