[0019] like Figures 1 to 8 As shown, a petrochemical pipeline welding device with auxiliary functions includes a welding material box 1, such as... Figure 1 , Figure 3 As shown, specifically, an insulation tank 2 is fixedly installed on the top of the solder box 1, a heater 3 is fixedly installed on the bottom inner wall of the insulation tank 2, a heating tank 4 is fixedly installed on the top of the heater 3, a spiral heat-conducting wire 5 is wound around the heating tank 4, the bottom end of the spiral heat-conducting wire 5 is fixedly connected to the heating end of the heater 3, and a feed pipe 6 is fixedly installed on the side wall of the insulation tank 2. The bottom end of the feed pipe 6 penetrates the side wall of the solder box 1 and communicates with the interior of the heating tank 4. Figure 2 , Figure 4 As shown, a conveying hose 7 is fixedly installed on the bottom side wall of the heat preservation bucket 2. One end of the conveying hose 7 is connected to the inside of the heating bucket 4. A positioning actuator is provided on the top of the welding box 1. A discharge pipe 24 is provided on the positioning actuator. One end of the conveying hose 7 is fixedly connected to one end of the discharge pipe 24. In this embodiment, a material conveying control valve is provided at the bottom of the heating tank 4. The control valve is connected to the material conveying hose 7, and a sealing cap is screwed or plugged into the top of the feed pipe 6.

[0020] The positioning actuator is used to control the movement of the discharge pipe 24 to the location of the pipe and welding plate, such as Figure 1 As shown, specifically, the positioning actuator includes a horizontal linear module 8 fixedly installed on the top of the solder box 1, and a vertical linear module 9 fixedly installed on the drive end of the horizontal linear module 8, such as... Figure 6 As shown, an arc-shaped frame 12 is fixedly installed at the drive end of the vertical linear module 9; In this embodiment, both the horizontal linear module 8 and the vertical linear module 9 can be common linear actuators in the prior art, such as linear motor modules, or mechanisms such as screw thread sleeves, belts and pulleys, chains and sprockets, etc., which control the linear movement of the drive end through threaded guidance or meshing. In addition to electrical energy, components such as cylinders and hydraulic rods can also be used as power sources. The horizontal linear module 8 and the vertical linear module 9 in this embodiment can adopt technical solutions including but not limited to the above, depending on the actual situation.

[0021] likeFigure 6 As shown, specifically, an arc-shaped slide rail 10 is fixedly installed at the bottom of the arc-shaped frame 12. The same arc-shaped slide rod 11 is slidably installed inside both the arc-shaped frame 12 and the arc-shaped slide rail 10. A gearbox 14 is fixedly installed on one side of the arc-shaped slide rail 10, and a motor box 13 is fixedly installed on one side of the gearbox 14. A sliding motor 15 is fixedly installed inside the motor box 13. A transmission shaft 16 is installed at the output end of the sliding motor 15. One end of the transmission shaft 16 extends into the interior of the gearbox 14 and is fixedly fitted with a transmission gear 17. A transmission hole communicating with the interior of the arc-shaped slide rail 10 is opened on the inner wall of the gearbox 14. Multiple evenly distributed meshing teeth 18 are fixedly installed on the inner ring side wall of the arc-shaped slide rail 10. The transmission gear 17 meshes with the meshing teeth 18, such as... Figure 5 , Figure 8 As shown, a movable plate 19 is fixedly installed at the bottom end of the arc-shaped slide bar 11, a first rotating arm 20 is fixedly installed on one side of the movable plate 19, a second rotating arm 21 is fixedly installed at the rotating end of the first rotating arm 20, a rotating frame 22 is fixedly installed at the rotating end of the second rotating arm 21, a fine-tuning electric push rod 23 is fixedly installed at one end of the rotating frame 22, an assembly frame 25 is fixedly installed at the telescopic end of the fine-tuning electric push rod 23, and a discharge pipe 24 is fixedly installed on the assembly frame 25.

[0022] In this embodiment, both the first rotating arm 20 and the second rotating arm 21 are driven to rotate by a servo motor with a self-locking structure. The movement trajectory of the rotating end of the first rotating arm 20 is located on a vertical plane. The rotation axis of the second rotating arm 21 is perpendicular to the rotation axis of the first rotating arm 20. The fixed end of the first rotating arm 20 is fixedly connected to the moving plate 19, and the fixed end of the second rotating arm 21 is fixedly connected to the rotating end of the first rotating arm 20.

[0023] More specifically, when using this auxiliary function petrochemical pipeline welding device, the outer wall of the oil pipeline to be maintained is first cleaned. If the crack in the pipeline is located at the point of contact with the ground, an arc-shaped trench is dug at the bottom of the pipeline. Then, welding particles are taken out from the welding material box 1, and the feed pipe 6 is opened to put the particles into the heating tank 4. The particles are heated in the heating tank 4 by the heater 3 and the spiral heat-conducting wire 5 and melted. The melting point of the welding material is much lower than that of the pipe metal, so the welding material will melt after a short heating time. During the melting process, the arc-shaped welding plate adapted to the pipeline is temporarily fixed to the crack using cable ties or metal glue. Then, the horizontal linear module 8 and the vertical linear module 9 adjust the position of the arc-shaped slide rail 10 through the arc-shaped frame 12. The motor box 13 then drives the arc-shaped slide rod 11 on the arc-shaped frame 1 through the meshing transmission gear 17 and meshing teeth 18. 2. The arc-shaped slide rail 10 slides up and down, bringing the cooling nozzle 27 close to the welding plate. Then, the control valve at the bottom of the heating tank 4 opens, and the molten solder is transported through the conveying hose 7 to the discharge pipe 24. The solder is then coated at the joint between the welding plate and the pipe through the discharge pipe 24. At the same time, the horizontal linear module 8, the vertical linear module 9, the motor box 13, the first rotating arm 20, the second rotating arm 21, and the fine-tuning electric push rod 23 work together to adjust the orientation of the discharge pipe 24 in real time, coating the gaps in the welding plate. Using the capillary principle, the molten solder seeps into the gaps, and the welding plate is brazed in the external space. There is no need to clean the inside of the pipe in advance, avoiding the use of arc welding. The positioning actuator provides a safe and reliable automatic welding auxiliary function for welding. The arc-shaped structure of the arc-shaped slide rail 11 makes it easy for the cooling nozzle 27 to enter the previously excavated arc-shaped tunnel, preventing safety accidents.

[0024] like Figure 8 As shown, specifically, a cooling fan 26 is fixedly installed on the assembly frame 25, and a cooling nozzle 27 is fixedly installed at the air outlet end of the cooling fan 26.

[0025] More specifically, by setting up a cooling fan 26, the cooling nozzle 27 and the discharge pipe 24 will follow similar trajectories. After the discharge pipe 24 coats the molten solder on the gap between the solder plate and the pipe, the cooling fan 26 on one side will blow air onto the coated solder through the cooling nozzle 27 as the assembly frame 25 moves, thereby accelerating the cooling and solidification of the solder and preventing the molten solder from slipping or dripping.

[0026] like Figure 7As shown, a limit box 33 is fixedly installed on the side of the gearbox 14 away from the motor box 13. Specifically, one end of the drive shaft 16 extends into the interior of the limit box 33. Two limit electric push rods 34 perpendicular to the axis of the drive shaft 16 are fixedly installed inside the limit box 33. The two limit electric push rods 34 are symmetrically distributed along the axis of the drive shaft 16. The telescopic ends of the limit electric push rods 34 are all facing the drive shaft 16 and are fixedly installed with arc-shaped fastening plates 35 that are adapted to the drive shaft 16.

[0027] More specifically, by setting limit electric push rods 34, after the sliding motor 15 adjusts the position of the arc-shaped slide rod 11, the two limit electric push rods 34 inside the limit box 33 drive the two arc-shaped fastening plates 35 to clamp the transmission shaft 16, thereby assisting the self-locking structure of the sliding motor 15 to lock the position of the arc-shaped slide rod 11, preventing the arc-shaped slide rod 11 from slipping during welding and affecting the welding quality.

[0028] like Figure 3 , Figure 4 As shown, specifically, the side wall of the solder box 1 has multiple annular vacuum layers 202 that are evenly distributed from top to bottom.

[0029] More specifically, by setting an annular vacuum layer 202, the multiple annular vacuum layers 202 on the inner wall of the heat preservation barrel 2 can reduce the thermal conductivity of the heat preservation barrel 2, improve the heat preservation effect of the heat preservation barrel 2, and thus ensure that the solder inside the heating barrel 4 can remain in a molten state for a long time.

[0030] like Figure 3 , Figure 4 As shown, a cylindrical hollow layer 201 is provided between the insulation tank 2 and the heating tank 4. Specifically, the spiral heat-conducting wire 5 is located inside the cylindrical hollow layer 201, and the cylindrical hollow layer 201 stores energy storage liquid. An insulation hose 28 is fixedly installed on one side of the insulation tank 2, and a material conveying hose 7 is located inside the insulation hose 28. A support ring frame 29 is fixedly installed inside the insulation hose 28, and multiple support ring frames 29 are fixedly sleeved on the material conveying hose 7. One end of the insulation hose 28 is connected to the inside of the cylindrical hollow layer 201, and the other end of the insulation hose 28 is fixedly connected to the assembly frame 25.

[0031] More specifically, by setting up a cylindrical hollow layer 201, when the heater 3 and the spiral heat-conducting wire 5 heat the solder, the energy storage liquid inside the cylindrical hollow layer 201 also heats up simultaneously, thereby playing the role of energy storage and heat preservation. At the same time, the heated energy storage liquid will flow between the interlayer of the heat preservation hose 28 and the material conveying hose 7 and the cylindrical hollow layer 201, thereby ensuring that the temperature of the solder stored inside the heating tank 4 and the solder conveyed inside the material conveying hose 7 is always kept in a molten state, reducing the amount of solder residue.

[0032] like Figure 2 , Figure 3 As shown, a push rod box 30 is fixedly installed on the top of the heat preservation barrel 2. Specifically, a pressing electric push rod 31 is fixedly installed inside the push rod box 30. The top of the heat preservation barrel 2 and the heating barrel 4 are provided with a connecting clearance channel. The telescopic end of the pressing electric push rod 31 extends through the clearance channel into the interior of the heating barrel 4 and is fixedly installed with a pressing rubber plate 32 that is adapted to the inner wall of the heating barrel 4.

[0033] More specifically, by setting up a pressure electric push rod 31, after the control valve at the bottom of the heating tank 4 is opened, the pressure electric push rod 31 at the top will drive the pressure plate 32 to slide downward inside the heating tank 4. The pressure plate 32 compresses the air inside the heating tank 4, thereby accelerating the conveying speed of the molten solder inside the conveying hose 7, while increasing the conveying volume and further reducing the amount of solder residue.

[0034] like Figure 5 As shown, a folded dustproof net cylinder 36 is fixedly installed at the bottom end of the arc-shaped slide rail 10. Specifically, the bottom end of the folded dustproof net cylinder 36 is fixedly installed on the movable plate 19, and the bottom end of the arc-shaped slide rod 11 is located inside the folded dustproof net cylinder 36.

[0035] More specifically, by setting up a folded dustproof net cylinder 36, when the arc-shaped slide rod 11 slides, the folded dustproof net cylinder 36 will be stretched or folded by the moving plate 19, thereby protecting the internal arc-shaped slide rod 11 and preventing soil or gravel from getting stuck on the arc-shaped slide rod 11 or the meshing teeth 18 when the arc-shaped slide rod 11 is inserted into the arc-shaped tunnel, which would cause damage to the transmission structure.

[0036] like Figure 2 Figure 3 As shown, an adsorption box 37 is fixedly installed on the top of the solder box 1. Specifically, an adsorption air pump 38 is fixedly installed on the top of the adsorption box 37. The output end of the adsorption air pump 38 is connected to the inside of the adsorption box 37, and the input end of the adsorption air pump 38 is connected to the inside of the feed pipe 6. Exhaust windows 39 are provided on both sides of the adsorption box 37.

[0037] More specifically, by setting up an adsorption box 37, after the solder is fed into the heating tank 4, the pressure plate 32 is reset, the adsorption air pump 38 is started, the air inside the heating tank 4 is drawn out and transported to the adsorption box 37 to be adsorbed and filtered by adsorption materials such as activated carbon particles, thereby preventing the harmful gases generated by the melting of the solder from being directly sprayed out through the feed pipe 6 when the solder is fed into the heating tank 4 again.

[0038] In summary: Before welding: First, clean the outer wall of the oil pipeline that needs maintenance. If the crack in the pipeline is located in contact with the ground, dig an arc-shaped tunnel at the bottom of the pipeline. Then, take out the welding particles from the welding material box 1 and open the feed pipe 6 to put the particles into the heating tank 4. The particles are heated by the heater 3 and the spiral heat-conducting wire 5 in the heating tank 4 and melted. The melting point of the welding material is much lower than that of the pipe metal. Therefore, the welding material will melt after a short heating time. During the melting process, use cable ties or metal glue to temporarily fix the arc-shaped welding plate that matches the pipeline to the crack. Then, the horizontal straight module 8 and the vertical straight module 9 adjust the position of the arc-shaped slide rail 10 through the arc-shaped frame 12. The motor box 13 then drives the arc-shaped slide rod 11 to slide up and down inside the arc-shaped frame 12 and the arc-shaped slide rail 10 through the meshing transmission gear 17 and meshing teeth 18, so that the cooling nozzle 27 is close to the welding plate. During welding: The control valve at the bottom of the heating tank 4 is opened, and the electric push rod 31 will drive the pressure plate 32 to slide downward inside the heating tank 4. The pressure plate 32 compresses the air inside the heating tank 4, and the molten solder is transported to the discharge pipe 24 through the conveying hose 7. Then, it is coated on the joint between the welding plate and the pipe through the discharge pipe 24. At the same time, the horizontal linear module 8, the vertical linear module 9, the motor box 13, the first rotating arm 20, the second rotating arm 21, and the fine-tuning electric push rod 23 cooperate with each other to adjust the orientation of the discharge pipe 24 in real time, and coat the gaps of the welding plate. Using the capillary principle, the molten solder seeps into the gaps. The cooling fan 26 on one side will blow air onto the coated solder through the cooling nozzle 27 as the assembly frame 25 moves, thereby accelerating the cooling and solidification of the solder, and carrying out brazing of the welding plate in the external space. After welding: After the solder is fed, the pressure plate 32 is reset, the adsorption air pump 38 is started, the air inside the heating tank 4 is extracted and transported to the adsorption box 37 to be adsorbed and filtered by adsorption materials such as activated carbon particles, so as to prevent the harmful gas generated by the melting of the solder from being directly sprayed out through the feed pipe 6 when the solder is fed into the heating tank 4 again.
