[0034] like Figures 1 to 10 As shown, a water supply and drainage pipe connection device for rainwater engineering includes an electric welding machine 1, as shown in FIG. Figure 1 As shown, a welding clamp 3 is provided on one side of the welding machine 1, and a cable 2 is fixedly connected between the welding machine 1 and the welding clamp 3. Figure 6 As shown, the welding clamp 3 holds the welding rod 16, as shown in FIG. Figure 1 As shown, both sides of the welding clamp 3 are provided with an upper fixed half ring 4, and the bottom of the upper fixed half ring 4 is provided with a lower fixed half ring 5. The upper fixed half ring 4 and the lower fixed half ring 5 located at the same place are symmetrically arranged, as shown in FIG. Figure 2 、 Figure 8 As shown, both ends of the upper fixed half ring 4 and the lower fixed half ring 5 are fixedly sleeved with an assembly plate 6, as shown in FIG. Figure 4 As shown, a plurality of evenly distributed assembly holes 601 are provided on the assembly plate 6, and a driving assembly for suspending the welding clamp 3 and driving the welding clamp 3 and the welding rod 16 to perform circular motion is provided between the two upper fixed semi-rings 4, and the driving assembly extends to the interior of the upper fixed semi-ring 4 and the lower fixed semi-ring 5; Specifically, when the water supply and drainage pipe connection device for rainwater engineering is used, the metal water supply and drainage pipe is first laid in the soil groove, and then an arc-shaped tunnel for convenient welding is dug at the joint of the pipes at both ends, so that one end of the pipe is suspended and the joint is cleaned, and then a welding rod 16 is clamped inside the welding clamp 3, and the welding clamp 3 together with the welding rod 16 is clamped inside the spring clamp 15, and then the two lower fixed semi-rings 5 ​​are buckled respectively. On the two sections of the pipeline, the lower fixed half ring 5 is made to slide along the pipeline to the bottom of the pipeline. At this time, the two connected upper fixed half rings 4 are buckled onto the pipeline, so that the upper fixed half ring 4 and the lower fixed half ring 5 are spliced ​​into a complete fixed ring, and then the upper fixed half ring 4 and the lower fixed half ring 5 are locked on the pipeline using bolts and assembly holes 601, so that the two sections of the pipeline are assembled together. After that, the electric welding machine 1 and the drive assembly are started, and the electric welding clamp 3 is used to weld the joints of the pipeline through the welding rod 16. At the same time, the drive assembly drives the electric welding clamp 3 to rotate slowly around the pipeline, thereby welding the joints of various parts of the pipeline into shape, completing the automatic welding of the metal pipeline. Finally, the electric welding clamp 3 is reversed and reset, and the upper fixed half ring 4 and the lower fixed half ring 5 are disassembled to complete the welding operation.

[0035] like Figure 7 、 Figure 8As shown, the drive assembly includes four half-toothed rings 7 rotatably mounted on the inside of two upper fixed half-rings 4 and two lower fixed half-rings 5, and a transmission box 8 is fixedly mounted on the top of each upper fixed half-ring 4. The transmission box 8 is connected to the inside of the upper fixed half-ring 4. A transmission shaft 9 is rotatably mounted inside the transmission box 8, and a transmission gear 10 meshing with the half-toothed ring 7 is fixedly sleeved inside the transmission shaft 9. Figure 3 As shown, a transmission motor 11 is fixedly installed on one side of the transmission box 8. In this embodiment, the transmission motor 11 adopts a stepping motor, and the drive assembly can also be controlled by a single motor. The output shaft of the transmission motor 11 is driven and connected to the transmission shaft 9. A transmission frame 12 is fixedly installed on the side wall of the half gear ring 7 located inside the upper fixed half ring 4. Semi-ring sliding holes 401 are opened on the side walls of the upper fixed half ring 4 and the lower fixed half ring 5. The two transmission frames 12 are slidably installed in the interior of two of the semi-ring sliding holes 401, as shown in FIG. Figure 5 As shown, one end of the two transmission frames 12 extends to the outside of the upper fixed half ring 4 and is fixedly installed with the same suspension frame 13, and a telescopic frame 14 is fixedly installed on the top of the suspension frame 13. The telescopic end of the telescopic frame 14 is fixedly installed with a spring clip 15. The welding clamp 3 is clamped inside the spring clip 15. The top of the suspension frame 13 is provided with an avoidance hole 1301, and the welding rod 16 is located inside the avoidance hole 1301. Specifically, by setting a driving component, after the two sections of the pipeline are fixed by using the upper fixed half ring 4 and the lower fixed half ring 5, the welding rod 16 is directed to the joint of the pipeline. At this time, the electric welding machine 1 is started, so that the welding clamp 3 welds the joint through the welding rod 16. At the same time, the transmission motors 11 on both sides start to drive the transmission gear 10 to rotate through the transmission shaft 9. When the upper fixed half ring 4 and the lower fixed half ring 5 are spliced ​​together, the half gear ring 7 inside them will also be connected end to end to form a complete gear ring. The transmission gear 10 will drive the gear ring inside the upper fixed half ring 4 and the lower fixed half ring 5 to rotate, and then drive the electric welding clamp 3 inside the spring clamp 15 to make a circular motion around the pipe through the transmission frame 12 and the suspension frame 13, so that the welding rod 16 is rotated around the annular joint for welding, completing the automatic welding of the metal pipe, so that the area at the bottom of the pipe that is difficult to operate can also be welded and formed, reducing the difficulty of welding metal water supply and drainage pipes.

[0036] like Figure 5As shown, a lifting electric push rod 17 parallel to the telescopic frame 14 is fixedly installed on the top of one of the transmission frames 12, and a lifting frame 18 is fixedly installed on the telescopic end of the lifting electric push rod 17, and the lifting frame 18 is fixedly installed on one side of the telescopic end of the telescopic frame 14; specifically, by setting the lifting electric push rod 17, in the process of the welding clamp 3 welding the pipe joint through the welding rod 16, the welding rod 16 will gradually consume and shorten. At this time, the lifting electric push rod 17 will drive the spring clamp 15 to move stably toward the suspension frame 13 through the lifting frame 18, so that the welding end of the welding rod 16 always keeps a light touch or a fixed distance from the pipe joint (based on actual welding requirements and factors such as the output current of the welding machine 1), so that the welding quality at each location is close to the same.

[0037] like Figure 6 As shown, a tilted laser pen 19 is fixedly installed at the bottom of the hanger 13, and the position of the laser pen 19 corresponds to the position of the welding rod 16. Specifically, by setting the laser pen 19, before using the bolt to lock the pipeline, it is necessary to first open the laser pen 19 at the bottom of the hanger 13, so that the laser pen 19 emits a laser toward the pipeline, thereby adjusting the position of the upper fixed half ring 4 and the lower fixed half ring 5 until the laser point is just located at the pipeline joint. Then, the upper fixed half ring 4 and the lower fixed half ring 5 can be further locked, thereby positioning the position of the welding rod 16 to avoid the problem of positional offset between the welding rod 16 and the joint.

[0038] like Figure 2 As shown, a fender 25 is fixedly mounted on one side of the suspension bracket 13; specifically, the fender 25 can prevent mud from falling from the tunnel from affecting the welding of the welding clamp 3 during the process of rotating welding around the pipe.

[0039] like Figure 8 As shown, the tops of the assembly plates 6 at both ends of the lower fixed half ring 5 are fixedly installed with positioning cone columns 20, and the bottoms of the assembly plates 6 at both ends of the upper fixed half ring 4 are provided with positioning sockets 602 that are compatible with the positioning cone columns 20; specifically, by providing the positioning cone columns 20, when the upper fixed half ring 4 and the lower fixed half ring 5 are spliced ​​into a complete ring, the positioning cone columns 20 at both ends of the lower fixed half ring 5 will be stuck in the positioning sockets 602 at both ends of the upper fixed half ring 4, thereby playing a role of pre-positioning before the upper fixed half ring 4 and the lower fixed half ring 5 are locked with bolts, preventing the internal tracks of the upper fixed half ring 4 and the lower fixed half ring 5 from being misaligned, resulting in the inability to splice the upper and lower half-toothed rings 7.

[0040] like Figure 9As shown, a mud guard cover 21 is placed on one end of the lower fixed half ring 5, and a through hole is opened on the top of the mud guard cover 21 to match the positioning cone column 20, and a plurality of assembly columns 22 that match the assembly holes 601 are fixedly installed on the bottom of the mud guard cover 21; specifically, by arranging the mud guard cover 21 and the mud guard plate 25, one end of the lower fixed half ring 5 in the initial state will be sleeved with a mud guard cover 21. After the lower fixed half ring 5 is buckled on the pipe, the lower fixed half ring 5 is slid to rotate along the pipe to the bottom of the pipe. During this process, the end sleeved with the mud guard cover 21 will slide in advance, thereby preventing the mud in the tunnel from falling into the interior of the lower fixed half ring 5 and affecting the subsequent transmission of the half-toothed ring 7 during the sliding of the lower fixed half ring 5. After the lower fixed half ring 5 rotates to the bottom of the pipe, the mud guard cover 21 is removed and the next step of splicing can be carried out.

[0041] like Figure 2 As shown, a positioning plate 23 is placed on one end of the two upper fixed half rings 4 on the same side, and a plurality of positioning rods 24 are slidably installed at both ends of the positioning plate 23. The positioning rods 24 are parallel to the axis of the upper fixed half ring 4, as shown in FIG. Figure 1 As shown, a plurality of positioning slots 402 compatible with the positioning rods 24 are provided on the side walls at both ends of the upper fixed half ring 4; specifically, by setting the positioning plate 23, in the initial state, both ends of the two upper fixed half rings 4 are equipped with a positioning plate 23, and the positioning plate 23 positions the two upper fixed half rings 4 through the positioning rods 24 and the positioning slots 402 at both ends to prevent the two from being misaligned and affecting the splicing. At the same time, the positioning plate 23 is convenient for construction workers to carry and transport by hand, reducing the difficulty of splicing the upper fixed half ring 4 and the lower fixed half ring 5.

[0042] like Figure 1 As shown, a tension adjustment frame 26 is provided between the welding clamp 3 and the welding machine 1. Figure 10 As shown, cable 2 assembly holes 601 are provided on both sides of the tension adjustment frame 26, and the cable 2 is inserted into the two cable 2 assembly holes 601. Two adjusting wheels 27 are rotatably installed inside the tension adjustment frame 26, and the cable 2 is located between the two adjusting wheels 27. Two adjusting motors 28 are fixedly installed on one side of the tension adjustment frame 26, and the output shafts of the two adjusting motors 28 are respectively driven and connected with the two adjusting wheels 27; specifically, by providing the tension adjustment frame 26, when the welding clamp 3 rotates around the pipe for welding, the cable 2 on one side thereof will move together with the welding clamp 3. At this time, the cable 2 inserted into the tension adjustment frame 26 will be controlled by the upper and lower adjusting wheels 27, and the two adjusting motors 28 on one side of the tension adjustment frame 26 will drive the two adjusting wheels 27 to rotate synchronously, thereby adjusting the tension of the cable 2, so that the section of the cable 2 between the welding clamp 3 and the tension adjustment frame 26 always maintains a certain tension, preventing the cable 2 from being too loose and causing obstruction to the welding operation.

[0043] In summary: Before welding: first lay the metal water supply and drainage pipes in the soil trench, then dig an arc-shaped tunnel at the joint of the pipes at both ends to facilitate welding, so that one end of the pipe is suspended and the joint is cleaned, then clamp a welding rod 16 inside the welding clamp 3, and clamp the welding clamp 3 together with the welding rod 16 inside the spring clamp 15, and then buckle the two lower fixed half rings 5 ​​on the two sections of the pipe respectively, so that the lower fixed half rings 5 ​​slide along the pipe to the bottom of the pipe, remove the mud cover 21, and then connect the two together. The upper fixing half ring 4 is buckled onto the pipe, so that the upper fixing half ring 4 and the lower fixing half ring 5 are spliced ​​into a complete fixing ring. The laser pen 19 at the bottom of the hanger 13 is opened, and the laser pen 19 is directed toward the pipe to emit laser light, thereby adjusting the positions of the upper fixing half ring 4 and the lower fixing half ring 5 until the laser point is just located at the pipe joint. The positioning plates 23 and positioning rods 24 on both sides are removed, and the upper fixing half ring 4 and the lower fixing half ring 5 are locked to the pipe using bolts and assembly holes 601, so that the two sections of pipe are assembled together.

[0044] During welding: start the electric welding machine 1, and make the electric welding clamp 3 weld the seam through the welding rod 16. At the same time, the transmission motors 11 on both sides start to drive the transmission gear 10 to rotate through the transmission shaft 9. When the upper fixed half ring 4 and the lower fixed half ring 5 are spliced ​​together, the half gear ring 7 inside them will also be connected end to end to form a complete gear ring. The transmission gear 10 will drive the gear ring inside the upper fixed half ring 4 and the lower fixed half ring 5 to rotate, and then drive the electric welding clamp 3 inside the spring clamp 15 to do a circular motion around the pipe through the transmission frame 12 and the suspension frame 13, so that The welding rod 16 rotates around the annular joint for welding. The cable 2 passing through the tension adjustment frame 26 is controlled by the upper and lower adjustment wheels 27. Two adjustment motors 28 on one side of the tension adjustment frame 26 drive the two adjustment wheels 27 to rotate synchronously, thereby adjusting the tension of the cable 2. At this time, the lifting electric push rod 17 drives the spring clamp 15 to move steadily toward the suspension frame 13 through the lifting frame 18, so that the welding end of the welding rod 16 always keeps a light touch or a fixed distance from the joint of the pipe, completing the automatic welding of the metal pipe.

[0045] After welding: the welding clamp 3 is reversed and reset, and the upper fixed half ring 4 and the lower fixed half ring 5 are disassembled to complete the welding operation.
