[0001] This invention relates to the field of equipment welding technology, specifically a branch-type heat dissipation ring network box welding device. Background Technology

[0002] Integrated primary and secondary ring main units are key equipment in power distribution networks, widely used in urban distribution networks, industrial parks, and new energy grid connection. Ring main units typically employ an inflatable sealed structure, with the gas chamber constructed from welded stainless steel plates and filled with insulating gas to ensure the reliability and safety of the equipment.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example: Figures 1-7 As shown, this invention provides a technical solution for a branch-type heat dissipation ring network box welding device. This device includes a welding table 1, a transmission groove 11 in the middle of the welding table 1, a welding port 12 on one side of the transmission groove 11, a sliding assembly 2 fixedly installed inside the welding port 12, and a welding assembly 3 fixedly connected to the sliding assembly 2. Arc-shaped connecting platforms 4 are symmetrically arranged at both ends of the transmission groove 11, and adjustable transmission components 5 are also symmetrically arranged inside the transmission groove 11. The arc-shaped connecting platforms 4 are movably connected to the adjustable transmission components 5. A welding fixture 6 is fixedly installed on the adjustable transmission component 5, and a dust suction component 7 is fixedly installed on the top of the welding fixture 6. A grinding port 13 is opened on the other side of the transmission groove 11, and a grinding assembly 8 is fixedly installed inside the grinding port 13. A large gap is left between the symmetrically arranged adjustable transmission components 5. Various equipment is fixed on the welding table 1, which is the main load-bearing component of the entire welding device. Component 2 is movably connected to welding assembly 3, enabling the entire welding assembly 3 to move and ensuring weld consistency. Welding assembly 3 can simultaneously weld both sides of the steel and adjust the distance between the two welding heads 3202 in real time, thus adapting to steel of different thicknesses and expanding its application range. The arc-shaped connecting platform 4 can limit and fix the movement of the adjustable transmission component 5. The two symmetrically arranged adjustable transmission components 5 can change the included angle between them, thereby changing the included angle between the two steel plates, which can adapt to the usage requirements of the branch heat dissipation ring network box. The welding clamp 6 can securely install the steel in the adjustable transmission component 5 to prevent displacement of the steel. The dust suction component 7 can suck up the dust and impurities generated during weld grinding in real time to avoid environmental pollution. The grinding component 8 can grind the welds on both sides of the steel simultaneously, which can shorten the grinding time and improve grinding efficiency.

[0020] First, the two pieces of steel to be welded are placed into the adjustable transmission components 5 on both sides. The adjustable transmission components 5 bring the two pieces of steel together tightly, and the clamping plate 62 is pressed firmly against the steel by the cylinder 61 for fixation. Then, the angle between the two pieces of steel is adjusted according to the heat dissipation channel requirements. At this point, the synchronous motor 54 is started, which drives the active gear 53 to rotate. The active gear 53 engages with the locking teeth 4201 in the active arc plate 42. One end of the adjustable transmission component 5 is fixed by the positioning post 5101, and the sliding post 5102 at the other end is embedded in the arc groove 4101. Therefore, the synchronous motor 54 enables the adjustable transmission component 5 to rotate around the positioning post 5101 as the center. Rotate until the included angle between the two adjustable transmission components 5 meets the requirements, then turn off the synchronous motor 54. At this time, the active gear 53 cannot rotate under the restriction of the synchronous motor 54. The adjustable transmission component 5 can be fixed by the cooperation between the gears. Then, the welding component 3 is moved by the sliding component 2. The distance between the two adjusting rods 32 can be changed by adjusting the motor 33, thereby changing the distance between the two welding heads 3202. Ensure that this distance is slightly greater than the thickness of the steel plate. Then, the welding heads 3202 symmetrically arranged in the welding component 3 can simultaneously weld the two sides of the steel. After the welding is completed, the welding component 3 is retracted into the welding port 12 by the sliding component 2 again.

[0021] The two sets of adjustable transmission components 5 symmetrically arranged in the transmission channel 11 have a large gap between them. This gap not only provides space for steel welding, but also allows the grinding component 8 to pass through, realizing an integrated process of welding and grinding. The grinding component 8 can prevent residual impurities in the weld from causing corrosion and affecting the sealing performance of the primary and secondary fusion ring mesh box.

[0022] The branch-type heat dissipation ring network box contains multiple complex heat dissipation channels. By cooperating with the adjustable transmission component 5 and the arc-shaped connecting platform 4, the included angle between the adjustable transmission components 5 can be adjusted, thereby changing the included angle between the two steel plates. This method can produce different heat dissipation channels to adapt to the usage requirements of the branch-type heat dissipation ring network box.

[0023] The welding assembly 3 can simultaneously weld both sides of the steel, which not only improves welding efficiency, but also ensures uniform distribution of thermal stress and minimizes welding deformation. In addition, the distance between the two welding heads 3202 can be adjusted in real time by adjusting the motor 33, enabling welding of steel of different thicknesses and expanding the range of applications.

[0024] The transmission groove 11 is connected to the grinding port 13. The side wall of the transmission groove 11 is symmetrically provided with positioning grooves 1101, and the two sides of the transmission groove 11 are provided with transition grooves 1102. The bottom of the welding table 1 is fixedly installed with a support rod 14.

[0025] The sliding assembly 2 includes a mounting plate 21, which is fixedly mounted on the side wall of the welding joint 12. A track 22 is provided on the mounting plate 21, and a sliding seat 23 is movably mounted on the track 22. The sliding seat 23 is fixedly connected to the storage bin 3101.

[0026] Welding assembly 3 includes a welding frame 31. A storage bin 3101 is fixedly installed in the middle of the welding frame 31. The storage bin 3101 is fixedly connected to a rotating plate 3102. A rotating shaft 3103 is provided inside the rotating plate 3102. Adjusting rods 32 are installed on both the upper and lower sides of the welding frame 31. A connecting end 3201 is provided on the adjusting rod 32 and is sleeved on the rotating shaft 3103. An adjusting motor 33 is installed on the welding frame 31. The output end of the adjusting motor 33 is connected to the adjacent adjusting rod 32. A welding head 3202 is installed at the end of the adjusting rod 32. The welding head 3202 is connected to the storage bin 3101 through a conveying pipe 3104. A vision sensor 34 is provided at the end of the adjusting rod 32 near the welding head 3202. Before welding, the thickness of the steel plate to be welded needs to be measured first, and the two adjusting rods are adjusted according to the thickness of the steel plate. To adjust the distance between the welding heads 3202, simply start the adjusting motor 33. The adjusting motor 33 adjusts the adjusting rod 32, which is connected to the rotating shaft 3103 via the connecting end 3201. Therefore, the adjusting motor 33 drives the adjusting rod 32 to rotate around the rotating shaft 3103, thereby changing the distance between the two welding heads 3202. Then, the sliding component 2 drives the sliding seat 23 to move, so that the entire welding component 3 is moved out of the welding port 12 and begins to weld the steel. During welding, the welding material is output from the storage bin 3101 and fed into the welding head 3202 through the feeding pipe 3104, providing sufficient welding material. During the welding process, the quality of the weld can be detected in real time by the vision sensor 34 at the end. When the weld quality is not good, the welding process needs to be terminated and re-welded.

[0027] A sliding arc plate 41 is provided on one side of the arc-shaped connecting platform 4, and an active arc plate 42 is provided on the other side of the arc-shaped connecting platform 4. An arc groove 4101 is provided in the sliding arc plate 41, and a locking tooth 4201 is evenly provided in the active arc plate 42. An inlet 43 is provided on the arc-shaped connecting platform 4, and steel can be put into the adjustable transmission component 5 from the inlet 43.

[0028] The adjustable transmission component 5 includes a frame 51, a transmission belt 52 installed inside the frame 51, positioning posts 5101 and sliding posts 5102 respectively provided on the side wall of the frame 51, and an active tooth 53 installed on the other side wall of the frame 51. The active tooth 53 is connected to the output end of the synchronous motor 54 and meshes with the locking tooth 4201.

[0029] The welding fixture 6 includes cylinders 61 symmetrically mounted on the side wall of the frame 51, and the output end of the cylinders 61 is fixedly connected to the clamping plate 62.

[0030] The dust collection component 7 includes a collection chamber 71, which is fixedly installed on the top of the clamping plate 62. The collection chamber 71 is provided with a dust suction port 72. The dust collection component 7 can continuously suck up the dust generated by the grinding component 8 during the grinding process through the dust suction port 72 and collect it through the collection chamber 71. This not only avoids environmental pollution, but also prevents the dust from adhering to the weld seam again and affecting the weld seam quality.

[0031] The grinding assembly 8 includes a connecting frame 81 fixed to the side wall of the grinding port 13. A pusher 82 is provided at one end of the connecting frame 81, and a push rod 8201 is provided at the output end of the pusher 82. A guide rail 8101 is provided at the top of the connecting frame 81, and a movable seat 83 is movably connected to the guide rail 8101. The push rod 8201 is connected to the movable seat 83, and grinding wheels 84 are symmetrically arranged on the movable seat 83. The grinding wheels 84 are connected to a drive motor 85. After welding, to prevent corrosion caused by residual impurities in the weld, it is necessary to remove the residual weld slag and weld beads, and grind the weld smooth to ensure the sealing quality of the weld. This is done by pushing... The actuator 82 pushes out the push rod 8201, which in turn pushes out the movable seat 83 connected to the push rod 8201. Finally, the two grinding wheels 84 fixed in the movable seat 83 can be pushed out from the grinding port 13 to grind the welded steel. The grinding wheels 84 and the movable seat 83 are movably connected. The distance between the upper and lower grinding wheels 84 can be adjusted according to the thickness of the steel. The two sets of grinding wheels 84 can grind both sides of the steel simultaneously, which not only improves grinding efficiency, but also ensures that the grinding effect on both sides is consistent, thereby guaranteeing the quality of the weld.

[0032] Working principle of the invention: First, place the two pieces of steel to be welded into the adjustable transmission components 5 on both sides. The adjustable transmission components 5 make the two pieces of steel stick together tightly, and the cylinder 61 presses the clamping plate 62 firmly to fix the steel. Then, adjust the angle between the two pieces of steel according to the heat dissipation channel requirements. At this time, simply start the synchronous motor 54, which drives the active gear 53 to rotate. The active gear 53 meshes with the locking teeth 4201 in the active arc plate 42. One end of the adjustable transmission component 5 is fixed by the positioning post 5101, and the sliding post 5102 at the other end is embedded in the arc groove 4101. Therefore, the synchronous motor 54 can make the adjustable transmission component 5 rotate around the positioning post 5101. When the angle between the two adjustable transmission components 5 meets the requirements, turn off the synchronous motor 54. At this time, the active gear 53 cannot rotate under the restriction of the synchronous motor 54. The adjustable transmission component 5 can be fixed by the cooperation between the gears.

[0033] Before welding, the thickness of the steel plate to be welded must first be measured, and the distance between the two welding heads 3202 is adjusted according to the thickness of the steel plate. At this time, it is only necessary to start the adjusting motor 33, and adjust the adjusting rod 32 by adjusting the adjusting motor 33. The adjusting rod 32 is connected to the rotating shaft 3103 through the connecting end 3201. Therefore, the adjusting motor 33 will drive the adjusting rod 32 to rotate around the rotating shaft 3103, thereby changing the distance between the two welding heads 3202. Then, the copper drum sliding assembly 2 drives the sliding seat 23 to move, so that the entire welding assembly 3 is moved out of the welding port 12 and welded to the steel. During the welding process, the quality of the formed weld can be detected in real time by the vision sensor 34 at the end. When the weld quality is not good, the welding process needs to be stopped and re-welded. Then, the sliding component 2 drives the welding component 3 to move. By adjusting the motor 33, the distance between the two adjusting rods 32 can be changed, thereby changing the distance between the two welding heads 3202. Ensure that this distance is slightly greater than the thickness of the steel plate. Then, the welding heads 3202 symmetrically arranged in the welding component 3 can simultaneously weld the two steels on both sides. After the welding is completed, the sliding component 2 is used to retract the welding component 3 into the welding port 12.

[0034] After welding, to prevent corrosion caused by residual impurities in the weld, it is necessary to remove the residual slag and weld beads, and grind the weld smooth to ensure the sealing quality of the weld. At this time, the push rod 8201 is pushed out by the pusher 82, which in turn pushes out the movable seat 83 connected to the push rod 8201. Finally, the two grinding wheels 84 fixed in the movable seat 83 can be pushed out from the grinding port 13 to grind the welded steel. The grinding wheels 84 and the movable seat 83 are movably connected, and the distance between the upper and lower grinding wheels 84 can be adjusted according to the thickness of the steel. The two sets of grinding wheels 84 can grind both sides of the steel simultaneously, which not only improves the grinding efficiency, but also ensures that the grinding effect on both sides is consistent, thereby ensuring the quality of the weld.
