[0015] Preferably, a spring three is fixedly mounted on one end of the magnetic plates that is away from each other, and the other end of the spring three is fixedly connected to the chute plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the clamping plate is opened, the drain pipe to be welded is placed in the clamping seat, and one end of the drain pipe is pushed to abut against the baffle, the clamping plate is rotated to fix the drain pipe in the clamping seat, and the hydraulic cylinder is started to drive the double-axis motor to descend, and the double-axis motor drives the rotating rods and gear rings on both sides to descend synchronously until the center of the double-axis motor output shaft and the center of the drain pipe are located at the same horizontal line, the hydraulic cylinder stops working, and then the screws on both sides are rotated to drive the clamping seats on both sides to move in a direction close to each other on the manufacturing table, so that the drain pipe on the clamping seat gradually approaches the gear rings on both sides, and one end of the drain pipe will gradually approach and squeeze the inclined surface of the outer scraper block, forcing the outer scraper block to slide upward on the rotating rod. The outer scraper blocks on both sides rotate synchronously, and the outer scraper blocks are tightly fitted on the outer wall of the drain pipe under the action of spring 1, which is convenient for cleaning the outer wall of the drain pipe at the welding point, and the impurity removal effect is better, thereby improving the welding quality of the welding point.

[0017] 2. In the present invention, the cleaning disc is in contact with the cut surface of the drain pipe at one end. When the rotating rod rotates, the gear shaft and the cleaning disc are also driven to rotate synchronously. Under the meshing action of the gear ring, the gear shaft drives the cleaning disc to rotate on the rotating rod, thereby effectively cleaning impurities on the welding surface of the drain pipe at one end, and also ensuring the subsequent welding quality.

[0018] 3. In the present invention, when the gear shaft follows the rotating rod to rotate to the lower side of the gear ring, the gear shaft will also drive the conical top block to move synchronously to the lower side of the gear ring, and the conical top block squeezes the front end of the movable plate, pushing the movable plate to slide on the support plate in a direction close to each other, compressing spring 2 and the airbag, and the gas in the airbag is ejected from the connecting pipe and the nozzle, and the ejected gas can spray the impurity water after cleaning the lower part of the drain pipe welding area into the interior of the drain pipe, so that the impurity water sprayed and cleaned at the lower side welding point of the drain pipe under the action of gravity can flow to the interior of the drain pipe, reducing the impurity water remaining in the lower part of the drain pipe welding area, and the impurities remaining after drying are still adhered to the welding area, affecting the subsequent welding quality.

[0019] 4. In the present invention, when the movable plates slide away from each other, the connecting rod will push the nozzle to slide upward on the vertical plate, so that the residual impurity water can be blown to the inside of the drain pipe farther away, reducing the backflow of impurity water. It can also ensure the cleanliness of the drainage pipe welding area and the subsequent welding quality.

[0020] 5. In the present invention, when the rotating rod rotates, it will also drive the inclined groove plate, the magnetic plate and the flexible arc panel to rotate synchronously. When the magnetic plate moves to the side close to the magnetic rod, the flexible arc panel just moves to the upper side of the inner bottom of the drain pipe. Under the action of the magnetic repulsive force, the magnetic plate is pushed to slide on the inclined groove plate, and the spring three is compressed. The flexible arc panel will move obliquely and gradually abut against the bottom of the drain pipe. It will gradually deform due to the squeezing of the bottom of the inner wall of the drain pipe. The flexible arc panel is conducive to sweeping the impurity water blown to the bottom of the drain pipe by the nozzle to the deeper inside of the drain pipe, which again reduces the situation where the impurity water flows back to the welding point of the drain pipe, thereby ensuring the subsequent welding quality of the drain pipe.

[0021] 6. In the present invention, the centralizing groove is provided to facilitate the collection of impurity water, reduce the overflow of impurity water from both sides of the flexible arc panel, and improve the sweeping quality of impurity water.

[0022] 7. In the present invention, when the outer scraper block is squeezed by the drain pipe and fits against the outer wall of the drain pipe, the outer scraper block will rise and squeeze the spring 1. At this time, the through groove provided will not affect the rotation of the cleaning disk and the protrusion. When the outer scraper block is not in contact with the drain pipe, the gear shaft will drive the cleaning disk to rotate and also drive the protrusion to rotate. The protrusion will intermittently hit the outer scraper block, causing the outer scraper block to shake under the action of the spring 1, which is conducive to shaking off the impurities adhered to the outer scraper block and improving the cleaning quality of the outer scraper block.

The rotating rod 11 is fixedly connected to the output shafts at both ends of the dual-axis motor 8 respectively. A cleaning disk 12 is fixedly installed on the ends of the rotating rod 11 that are away from each other. An external scraper block 13 is provided on the upper side of the cleaning disk 12. The ends of the external scraper blocks 13 that are away from each other are inclined surfaces, and the lower ends of the external scraper blocks 13 are arc surfaces. The ends of the external scraper blocks 13 that are close to each other are slidably connected to the rotating rod 11. A spring 14 is fixedly installed on the upper end of the external scraper block 13, and the upper end of the spring 14 is fixedly installed on the rotating rod 11. A through groove 15 is provided at the lower end of the external scraper block 13 corresponding to the cleaning disk 12, and a convex block 16 is fixedly installed on the outer side of the cleaning disk 12 corresponding to the external scraper block 13. When working, open the clamp 3, place the drain pipe to be welded in the clamp seat 2, and push one end of the drain pipe to abut against the baffle 4, rotate the clamp 3 to fix the drain pipe in the clamp seat 2, start the hydraulic cylinder 7 to drive the double-axis motor 8 to descend, and the double-axis motor 8 drives the rotating rods 11 and the gear rings 9 on both sides to descend synchronously until the center of the output shaft of the double-axis motor 8 and the center of the drain pipe are on the same horizontal line, the hydraulic cylinder 7 stops working, and then rotates the screw rods 5 on both sides to drive the clamp seats 2 on both sides to move in a direction close to each other on the manufacturing table 1, so that the drain pipe on the clamp seat 2 gradually approaches the gear rings 9 on both sides, and one end of the drain pipe will gradually approach and squeeze the inclined surface of the outer scraper block 13, forcing the outer scraper block 13 to move on the rotating rod 1 1 slides upward, compressing spring 14 until the lower end of the outer scraper block 13 is in contact with the outer end of the drain pipe, and the outer scraper block 13 stops sliding upward. As the drain pipe continues to approach the gear ring 9, the ends of the drain pipes on both sides that are close to each other will abut and fit with the cleaning disk 12, and the screw 5 stops rotating. At this time, the staff holds the water spray pipe to clean the welding area of ​​the drain pipe. At the same time, the dual-axis motor 8 is started synchronously to drive the rotating rods 11 on both sides to rotate. The rotating rods 11 drive the outer scrapers 13 on both sides to rotate synchronously. The outer scraper blocks 13 are tightly attached to the outer wall of the drain pipe under the action of the spring 14, which is convenient for cleaning impurities on the outer wall of the drain pipe welding. The impurity removal effect is better, thereby The welding quality of the welding joint is improved. At the same time, since the cleaning disc 12 is in contact with the cross-section of the end close to the drain pipe, when the rotating rod 11 rotates, the gear shaft 10 and the cleaning disc 12 will also be driven to rotate synchronously. Under the meshing action of the gear ring 9, the gear shaft 10 will drive the cleaning disc 12 to rotate on the rotating rod 11, so that the impurities on the welding surface of the end close to each other of the drain pipe can be effectively cleaned, and the subsequent welding quality is also guaranteed. When the outer scraper block 13 is squeezed by the drain pipe and fits the outer wall of the drain pipe, the outer scraper block 13 will rise and squeeze the spring 14. At this time, the through groove 15 provided does not affect the rotation of the cleaning disc 12 and the protrusion 16. When the outer scraper block 13 is not in contact with the drain pipe, When the gear shaft 10 drives the cleaning disk 12 to rotate, it will also drive the protrusion 16 to rotate. The protrusion 16 will intermittently hit the outer scraper block 13, causing the outer scraper block 13 to shake under the action of the spring 14, which is beneficial to shaking off the impurities adhered to the outer scraper block 13 and improving the cleaning quality of the outer scraper block 13. When the drainage pipe welding position is cleaned, the screw rods 5 on both sides are rotated to drive the drainage pipes on both sides to separate from the outer scraper block 13 and the cleaning disk 12, and the hydraulic cylinder 7 is started to drive the dual-axis motor 8, the gear ring 9 and the rotating rod 11 to rise synchronously, so that the gear ring 9 and other components rise away from between the drainage pipes on both sides, and then the screw rod 5 is rotated to drive the drainage pipes on both sides to approach and abut each other, so that the connection between the drainage pipes on both sides can be welded.

[0027] As an embodiment of the present invention, there is also a backflow prevention mechanism for preventing the cleaned sewage at the bottom of the drain pipe from flowing back to the lower side of the welding surface. The backflow prevention mechanism includes a nozzle 17 arranged at the side of the gear ring 9 close to each other. The ends of the nozzles 17 close to each other are fixedly connected with a connecting pipe 18, and the other end of the connecting pipe 18 is fixedly connected with an air bag 19. The ends of the air bags 19 close to each other are fixedly installed with a support plate 20, and the ends of the support plates 20 away from each other are fixedly installed on the gear ring 9. The ends of the air bags 19 away from each other are fixedly installed with a movable plate 21, and the upper end of the movable plate 21 is slidably installed on the support plate 20. A spring 22 is fixedly installed between the movable plate 21 and the support plate 20, and the ends of the gear shafts 10 close to each other are fixedly installed with a conical top corresponding to the movable plate 21. Block 23, the front end of the movable plate 21 is hinged with a connecting rod 24, the upper end of the connecting rod 24 is hinged with the nozzle 17, the ends of the nozzles 17 that are close to each other are slidably installed with a vertical plate 25, and the lower end of the vertical plate 25 is fixedly installed on the support plate 20, the sides of the rotating rods 11 that are away from each other are provided with flexible arc panels 26, and the ends of the flexible arc panels 26 that are away from each other are provided with concentrated grooves 27, and the ends of the flexible arc panels 26 that are close to each other are fixedly installed with magnetic plates 28, and magnetic rods 29 are fixedly installed on the corresponding magnetic plates 28 on the gear ring 9, and the rear end of the magnetic plate 28 is slidably installed with an inclined slot plate 30, and the ends of the inclined slot plates 30 that are close to each other are fixedly installed on the rotating rod 11, and the ends of the magnetic plates 28 that are away from each other are fixedly installed with springs three 31, and the other end of the springs three 31 is fixedly connected to the inclined slot plate 30; During operation, when the gear shaft 10 follows the rotating rod 11 to rotate to the lower side of the gear ring 9, the gear shaft 10 will also drive the conical top block 23 to move synchronously to the lower side of the gear ring 9, and the conical top block 23 squeezes the front end of the movable plate 21, pushing the movable plate 21 to slide in a direction close to each other on the support plate 20, compressing the spring 22 and the air bag 19, and the gas in the air bag 19 is ejected from the connecting pipe 18 and the nozzle 17, and the ejected gas can spray the impurity water after cleaning the lower part of the drainage pipe welding area into the interior of the drainage pipe, so that the spray cleaning impurity water flowing to the lower side welding of the drainage pipe under the action of gravity can flow to the interior of the drainage pipe, reducing the impurity water remaining in the lower part of the drainage pipe welding area. The residual impurities after drying still adhere to the welding area, affecting the subsequent welding quality, when the movable plates 21 slide away from each other, under the action of the connecting rod 24, the nozzle 17 will be pushed to slide upward on the vertical plate 25, so that the residual impurity water can be blown to the interior of the drainage pipe farther away, reducing the impurities The water reflux situation can also ensure the cleanliness of the drainage pipe welding area and the subsequent welding quality. When the rotating rod 11 rotates, it will also drive the inclined groove plate 30, the magnetic plate 28 and the flexible arc panel 26 to rotate synchronously. When the magnetic plate 28 moves to the side close to the magnetic rod 29, the flexible arc panel 26 just moves to the upper side of the inner bottom of the drainage pipe. Under the action of the magnetic repulsion, the magnetic plate 28 is pushed to slide on the inclined groove plate 30, and the spring 31 is compressed. The flexible arc panel 26 will move obliquely and gradually abut against the bottom of the drainage pipe. It is gradually deformed by the squeezing of the bottom of the inner wall of the drainage pipe. The set flexible arc panel 26 is conducive to sweeping the impurity water sprayed by the nozzle 17 to the bottom of the drainage pipe to a deeper part of the drainage pipe, which again reduces the situation of impurity water reflux to the drainage pipe welding point, ensuring the subsequent drainage pipe welding quality. The set concentration groove 27 is convenient for collecting impurity water, reducing the situation of impurity water overflowing from both sides of the flexible arc panel 26, and improving the sweeping quality of impurity water.

[0028] Working principle: When the present invention is used, the clamping plate 3 is opened, the drain pipe to be welded is placed in the clamping seat 2, and one end of the drain pipe is pushed to abut against the baffle 4, the clamping plate 3 is rotated to fix the drain pipe in the clamping seat 2, and the hydraulic cylinder 7 is started to drive the double-axis motor 8 to descend, and the double-axis motor 8 drives the rotating rods 11 and the gear rings 9 on both sides to descend synchronously until the center of the output shaft of the double-axis motor 8 and the center of the drain pipe are located at the same horizontal line, the hydraulic cylinder 7 stops working, and then the screw rods 5 on both sides are rotated to drive the clamping seats 2 on both sides to move in a direction approaching each other on the manufacturing table 1, so that the drain pipe on the clamping seat 2 gradually approaches the gear rings 9 on both sides, and one end of the drain pipe will gradually approach and squeeze the inclined surface of the outer scraper block 13, forcing the outer scraper block 13 to slide upward on the rotating rod 11, compressing the spring 14, until the outer When the lower end of the scraper block 13 is in contact with the outer end of the drain pipe, the outer scraper block 13 stops sliding upward. As the drain pipe continues to approach the gear ring 9, the ends of the drain pipes on both sides that are close to each other will abut and fit with the cleaning disk 12, and the screw 5 stops rotating. At this time, the staff holds the water spray pipe to clean the welding area of ​​the drain pipe. At the same time, the dual-axis motor 8 is started synchronously to drive the rotating rods 11 on both sides to rotate. The rotating rods 11 drive the outer scraper blocks 13 on both sides to rotate synchronously. The outer scraper block 13 is tightly fitted on the outer wall of the drain pipe under the action of the spring 14, which is convenient for cleaning impurities on the outer wall of the drain pipe welding point. The impurity removal effect is better, thereby improving the welding quality of the welding point. At the same time, the cleaning disk 12 abuts against the cross-section of the end of the drain pipe that is close to each other. When the rotating rod 11 rotates, the gear shaft 10 and the cleaning disk 12 will also be driven to rotate synchronously. Under the meshing action of the gear ring 9, the gear shaft 10 will drive the cleaning disk 12 to rotate on the rotating rod 11, so that the impurities on the welding surface of the end of the drainage pipe close to each other can be effectively cleaned, and the subsequent welding quality is also guaranteed. After cleaning, the staff stops spraying water to clean the welding part. When the gear shaft 10 rotates to the lower side of the gear ring 9 following the rotating rod 11, the gear shaft 10 will also drive the conical top block 23 to move synchronously to the lower side of the gear ring 9, and the conical top block 23 squeezes the front end of the movable plate 21, pushing the movable plate 21 to slide on the support plate 20 in a direction close to each other, compressing the spring 22 and the airbag 19, and the gas in the airbag 19 is discharged from the connecting rod 11. The pipe 18 and the nozzle 17 are sprayed out, and the sprayed gas can spray the impurity water after cleaning the lower part of the drainage pipe welding area into the interior of the drainage pipe, so that the impurity water sprayed and cleaned at the lower welding part of the drainage pipe under the action of gravity can flow into the interior of the drainage pipe, reducing the impurity water remaining in the lower part of the drainage pipe welding area. The residual impurities after drying still adhere to the welding area, affecting the subsequent welding quality. When the movable plates 21 slide away from each other, under the action of the connecting rod 24, the nozzle 17 will be pushed to slide upward on the vertical plate 25, so that the residual impurity water can be blown to the interior of the drainage pipe farther away, reducing the backflow of impurity water, and also ensuring the cleanliness of the drainage pipe welding area and the subsequent welding quality. When the rotating rod 11 rotates,The chute plate 30, magnetic plate 28 and flexible arc panel 26 will also be driven to rotate synchronously. When the magnetic plate 28 moves to the side close to the magnetic rod 29, the flexible arc panel 26 just moves to the upper side of the inner bottom of the drain pipe. Under the action of the magnetic repulsion, the magnetic plate 28 is pushed to slide on the chute plate 30, compressing the spring 31. The flexible arc panel 26 will move obliquely and gradually abut against the bottom of the drain pipe. It is gradually deformed by the squeezing of the bottom of the inner wall of the drain pipe. The flexible arc panel 26 is conducive to sweeping the impurity water blown to the bottom of the drain pipe by the nozzle 17 to the deeper inside of the drain pipe, which again reduces the situation of impurity water flowing back to the welding point of the drain pipe, ensuring the welding quality of the subsequent drain pipe. The concentrated groove 27 is convenient for collecting impurity water, reducing the situation of impurity water overflowing from both sides of the flexible arc panel 26, and improving the sweeping quality of impurity water. When the outer scraper block 13 is squeezed by the drain pipe When the pressure is pressed against the outer wall of the drain pipe, the outer scraper block 13 will rise and squeeze the spring 14. At this time, the through groove 15 does not affect the rotation of the cleaning disc 12 and the protrusion 16. When the outer scraper block 13 is not in contact with the drain pipe, the gear shaft 10 drives the cleaning disc 12 to rotate and also drives the protrusion 16 to rotate. The protrusion 16 will intermittently hit the outer scraper block 13, causing the outer scraper block 13 to vibrate under the action of the spring 14, which is conducive to shaking off the impurities adhered to the outer scraper block 13 and improving the cleaning quality of the outer scraper block 13. When the drain pipe welding part is cleaned, the screw rods 5 on both sides are rotated to drive the drain pipes on both sides to separate from the outer scraper block 13 and the cleaning disc 12, and the hydraulic cylinder 7 is started to drive the dual-axis motor 8, the gear ring 9 and the rotating rod 11 to rise synchronously, so that the gear ring 9 and other components rise away from the drain pipes on both sides, and then the screw rod 5 is rotated to drive the drain pipes on both sides to approach and abut each other, so that the connection of the drain pipes on both sides can be welded.
