Description

Technical Field

[0001] The invention relates to the technical field of transformer supporting equipment, in particular to a supporting device for preventing transformer welding errors. Background Art

[0002] Transformers play a key role in many fields such as power systems, and their performance directly affects the stability and safety of the entire system;

[0003] When welding the transformer, a supporting device is needed to support the transformer to prevent welding errors.

[0018] The present invention has the following beneficial effects:

[0019] 1. The present invention first places the transformer to be welded on the top of the main body through an external conveying device. When the transformer is placed on the top of the main body, the weight of the transformer itself presses the intermediate shaft to move it downward. When the intermediate shaft moves downward, the downward movement of the intermediate shaft drives the rotating plate and the special-shaped double-toothed plate to move downward synchronously. When the intermediate shaft drives the special-shaped double-toothed plate to move downward, the downward movement of the special-shaped double-toothed plate drives the gear shaft to rotate. When the gear shaft rotates, the rotating belt of the gear shaft rotates in the bidirectional threaded cylinder inside the T-shaped cylinder plate and can rotate when the gear shaft rotates. So that the T-type cylinder plate moves inside the adsorption box. When the T-type cylinder plate moves, the movement of the T-type cylinder plate will squeeze the gas between the T-type cylinder plate and the adsorption box. At this time, the gas will enter the hollow box through the connecting pipe after being squeezed, and then the intermediate shaft will drive the rotating plate to move downward. At this time, when the rotating plate moves downward, the rotating plate will be pulled by the hollow plate to rotate in the direction of the intermediate shaft. When the rotating plate rotates in the direction of the intermediate shaft, the rotation of the rotating plate will push the hollow box through the limit rod to make it rotate inside the hollow plate. When the hollow box rotates, it will When the hollow box is rotated to be in a vertical state, when the transformer continues to move downward, the lifting cylinder on the hollow box will be inserted into the cavity inside the transformer. At the same time, when the transformer is in a vertical state inside the rectangular groove, the lifting cylinder will be restricted by the rectangular groove and move upward on the inner wall of the hollow box. When the lifting cylinder moves upward, the bidirectional threaded groove on the inner wall of the lifting cylinder will drive the raised hollow cylinder to rotate through the bulge on the surface of the raised hollow cylinder. When the raised hollow cylinder rotates, it will drive the piston plate to rotate inside the hollow box through the right-angle groove on the raised hollow cylinder. Move downward. When the piston plate moves downward, the movement of the piston plate will squeeze the gas inside the hollow box. At this time, the gas will enter the interior of the airbag ball through the raised hollow cylinder after being squeezed and expand the airbag ball. Later, when the lifting cylinder is inserted into the cavity of the transformer, the transformer can be accurately positioned to prevent the transformer from shifting during the welding process. At the same time, when the airbag ball expands, it can ensure a close fit with the transformer while reducing the impact and damage of rigid contact on the internal structure and sensitive components of the transformer, thereby ensuring stability during the welding process.

[0020] 2. In the present invention, when the downward movement of the intermediate shaft drives the special-shaped double-toothed plate to move downward, the downward movement of the special-shaped double-toothed plate will drive the gear shaft to rotate. When the gear shaft rotates, it will rotate in the bidirectional thread groove inside the gear shaft through the insertion rod on the surface. When the gear shaft rotates, the rotation of the insertion rod can drive the T-shaped cylinder plate to move inside the adsorption box. When the T-shaped cylinder plate moves, negative pressure can be generated inside the adsorption box and the bottom of the transformer can be adsorbed through the adsorption holes on the adsorption box, so that the transformer can be firmly locked on the main body, which can further reduce the possibility of errors in the welding process and ensure that the transformer will not slide or fall from the main body, thereby avoiding potential safety hazards and losses.

[0021] 3. In the present invention, when the middle shaft moves downward, the L plate is driven to move through the rotating plate, and the movement of the L plate will drive the T-type tube to move synchronously. When the T-type tube moves, the threaded shaft inside the T-type tube will slide on the surface of the raised rod. When the threaded shaft slides on the surface of the raised rod, the protrusion on the raised rod will slide in the two-way thread groove three inside the movable plate two and drive the threaded shaft to rotate inside the T-type tube. When the threaded shaft rotates, it will drive the grille plate to rotate. When the grille plate rotates, it will drive the movable plate to move through the wave groove on the side wall of the grille plate. When the movable plate moves, it will push the arc plate through the middle plate to make it rotate on the side wall of the inclined plate. When the arc plate rotates, the rotation of the arc plate will pull the spring rod to move backward, and the spring on the spring rod will also push the spring rod to move backward. When the spring rod moves backward, the movement of the spring rod will pull the middle part of the rubber block and cause its outer surface to bulge outward. When the hollow box 2 moves, the rubber block can be driven to squeeze the surface of the transformer. This squeezing can not only increase the stability of the support of this device, but also help to reduce vibration and displacement during welding. At the same time, the rubber block can produce a certain buffering effect when squeezed, which can reduce the direct impact between the transformer and the supporting device, and can further improve the stability and durability of the device.

[0022] 4. In the present invention, when the threaded shaft rotates on the surface of the raised rod along with the movement of the hollow box 2, the rotation of the threaded shaft will drive the raised ring to slide on the surface of the T-tube, and when the raised ring slides, it can drive multiple movable plates 2 to expand outward, and when the movable plate 2 expands, it will drive the movable plate 2 to expand synchronously. At the same time, when the T-tube plate moves inside the adsorption box and squeezes the gas in the adsorption box, most of the squeezed gas will enter the T-tube through the air outlet pipe. At this time, the movement of the raised ring will drive the moving frame to move inside the T-tube and separate from the air inlet of the long tube. Then, when the threaded shaft rotates, the rotation of the threaded shaft will drive the grille plate to rotate, and when the grille plate rotates, it will throw the gas in the T-tube into the long tube. At this time, the gas will enter the flexible plate through the long tube and expand the flexible plate. At this time, the movement of the raised ring will drive the moving frame to move inside the T-tube. And it is closed with the air inlet of the long tube, and then the expanded flexible plate will be in close contact with the surface of the transformer, and when the flexible plate expands outward, the expansion of the movable plate two will drive the elastic ring to expand, and when the elastic ring expands, it will drive the T-bar through the rubber shaft, so that one end of the T-bar inside the threaded shaft contacts the side wall of the hollow part of the threaded shaft, and then when the threaded shaft rotates, the T-bar can be driven to rotate by friction, and when the T-bar rotates, it will drive the rubber shaft to rotate by friction, and the rubber shaft will be twisted and shortened when it rotates. When the rubber shaft shortens, the T-bar will be pulled inward by the elastic ring and form a pulling force on four sides on the surface of the transformer, so as to enhance the supporting force of the transformer and form a more stable supporting structure, which greatly enhances the clamping stability of the transformer, makes it difficult for it to displace during the welding process, and further enhances the supporting force of the transformer.

[0049] The hollow box 601 is provided with a rotating mechanism 8 inside, and the rotating mechanism 8 includes an elastic ring 801 fixedly connected between the two movable plates 703, and the outer surfaces of the plurality of elastic rings 801 are fixedly connected with rubber shafts 802, and the ends of the plurality of rubber shafts 802 away from the elastic rings 801 are rotatably connected with T-shaped rods 803, and the ends of the T-shaped rods 803 away from the rubber shafts 802 penetrate into the hollow inside the threaded shaft 705, and the outer surface of the T-shaped rods 803 is provided with a moving frame 804, and the end of the moving frame 804 close to the rubber shaft 802 is connected to the raised ring The side wall of 702 is fixedly connected, and the movable frame 804 is slidably connected to the inside of the T-tube 701. The expansion of the movable plate 703 will drive the elastic ring 801 to expand. When the elastic ring 801 expands, it will drive the T-bar 803 through the rubber shaft 802, so that one end of the T-bar 803 inside the threaded shaft 705 contacts the side wall of the hollow part of the threaded shaft 705. Then, when the threaded shaft 705 rotates, the T-bar 803 can be driven to rotate by friction. When the T-bar 803 rotates, it will drive the rubber shaft 802 to rotate by friction.

[0050] When in use, firstly, the transformer to be welded is placed on the top of the main body 1 through an external conveying device. When the transformer is placed on the top of the main body 1, the weight of the transformer itself will press the intermediate shaft 201 to move it downward. When the intermediate shaft 201 moves downward, the downward movement of the intermediate shaft 201 will drive the rotating plate 204 and the special-shaped double-toothed plate 202 to move downward synchronously. When the intermediate shaft 201 drives the special-shaped double-toothed plate 202 to move downward, the downward movement of the special-shaped double-toothed plate 202 will drive the gear shaft 304 to rotate. When the gear shaft 304 rotates, the rotating belt of the gear shaft 304 rotates in the bidirectional threaded cylinder inside the T-shaped cylinder plate 303 and when the gear shaft 304 rotates, the T-shaped The cylinder plate 303 moves inside the adsorption box 301. When the T-shaped cylinder plate 303 moves, the movement of the T-shaped cylinder plate 303 will squeeze the gas between the T-shaped cylinder plate 303 and the adsorption box 301. At this time, the gas will enter the hollow box 401 through the connecting pipe 305 after being squeezed, and then the intermediate shaft 201 drives the rotating plate 204 to move downward. At this time, when the rotating plate 204 moves downward, the rotating plate 204 will be pulled by the hollow plate 205 to rotate in the direction of the intermediate shaft 201. When the rotating plate 204 rotates in the direction of the intermediate shaft 201, the rotation of the rotating plate 204 will push the hollow box 401 through the limit rod 207 to make it rotate inside the hollow plate 205, and the air When the core box 401 rotates, it will form a vertical state inside the rectangular groove 103. When the hollow box 401 rotates to a vertical state, when the transformer continues to move downward, the lifting cylinder 402 on the hollow box 401 will be inserted into the cavity inside the transformer. At the same time, when the transformer forms a vertical state inside the rectangular groove 103, the lifting cylinder 402 will be restricted by the rectangular groove 103 and move upward on the inner wall of the hollow box 401. When the lifting cylinder 402 moves upward, the bidirectional threaded groove 2 on the inner wall of the lifting cylinder 402 will drive the raised hollow cylinder 501 to rotate through the bulge on the surface of the raised hollow cylinder 501. When the raised hollow cylinder 501 rotates, it will be driven by the right-angle groove on the raised hollow cylinder 501. The movable piston plate 503 moves downward inside the hollow box 401. When the piston plate 503 moves downward, the movement of the piston plate 503 will squeeze the gas inside the hollow box 401. At this time, the gas will enter the interior of the airbag ball 403 through the raised hollow cylinder 501 after being squeezed, and expand the airbag ball 403. After that, when the lifting cylinder 402 is inserted into the cavity of the transformer, the transformer can be accurately positioned, and the position shift of the transformer during the welding process can be prevented. At the same time, when the airbag ball 403 expands, it can ensure a close fit with the transformer while reducing the impact and damage of the rigid contact on the internal structure and sensitive components of the transformer, thereby ensuring stability during the welding process.

[0051] When the downward movement of the intermediate shaft 201 drives the special-shaped double-toothed plate 202 to move downward, the downward movement of the special-shaped double-toothed plate 202 will drive the gear shaft 304 to rotate. When the gear shaft 304 rotates, it will rotate in the bidirectional threaded groove inside the gear shaft 304 through the insertion rod on the surface. When the gear shaft 304 rotates, the rotation of the insertion rod can drive the T-shaped barrel plate 303 to move inside the adsorption box 301. When the T-shaped barrel plate 303 moves, negative pressure can be generated inside the adsorption box 301 and the bottom of the transformer can be adsorbed through the adsorption holes on the adsorption box 301, so that the transformer can be firmly locked on the main body 1, which can further reduce the possibility of errors in the welding process and ensure that the transformer will not slide or fall from the main body 1, thereby avoiding potential safety hazards and losses.

[0052] When the intermediate shaft 201 moves downward, the L plate 206 is driven to move through the rotating plate 204, and the movement of the L plate 206 drives the T-shaped cylinder 701 to move synchronously. When the T-shaped cylinder 701 moves, the threaded shaft 705 inside the T-shaped cylinder 701 will slide on the surface of the raised rod 102. When the threaded shaft 705 slides on the surface of the raised rod 102, the protrusion on the raised rod 102 will slide in the two-way thread groove three inside the movable plate 2 703 and drive the threaded shaft 705 to rotate inside the T-shaped cylinder 701. When the threaded shaft 705 rotates, it drives the grille plate to rotate. When the grille plate rotates, it drives the movable plate 602 to move through the wave groove on the side wall of the grille plate. When the movable plate 602 moves, it pushes the arc plate 602 through the intermediate plate 603. 04 makes it rotate on the side wall of the inclined plate. When the arc plate 604 rotates, the rotation of the arc plate 604 will pull the spring rod 605 to move backward, and at the same time, the spring on the spring rod 605 will also push the spring rod 605 to move backward. When the spring rod 605 moves backward, the movement of the spring rod 605 will pull the middle part of the rubber block and cause its outer surface to bulge outward. When the hollow box 601 moves, the rubber block can be driven to squeeze the surface of the transformer. This squeezing can not only increase the stability of the support of this device, but also help to reduce vibration and displacement during welding. At the same time, the rubber block can produce a certain buffering effect when squeezed, which can reduce the direct impact between the transformer and the supporting device, and can further improve the stability and durability of the device.

[0053] When the threaded shaft 705 rotates on the surface of the raised rod 102 as the hollow box 601 moves, the rotation of the threaded shaft 705 drives the raised ring 702 to slide on the surface of the T-shaped cylinder 701. When the raised ring 702 slides, it can drive multiple movable plates 703 to expand outward. When the movable plate 703 expands, it will drive the movable plate 703 to expand synchronously. At the same time, when the T-shaped cylinder plate 303 moves inside the adsorption box 301 and squeezes the gas in the adsorption box 301, most of the squeezed gas will pass through The gas outlet pipe enters into the T-shaped cylinder 701. At this time, the movement of the raised ring 702 drives the movable frame 804 to move inside the T-shaped cylinder 701 and separate from the gas inlet of the long tube. Then, when the threaded shaft 705 rotates, the rotation of the threaded shaft 705 drives the grille plate to rotate. When the grille plate rotates, the gas in the T-shaped cylinder 701 is thrown into the long tube. At this time, the gas enters into the flexible plate 704 through the long tube and expands the flexible plate 704. At this time, the movement of the raised ring 702 drives the movable frame 804 to move inside the T-shaped cylinder 701. 1 and closes with the air inlet of the long tube, and then the expanded flexible plate 704 will be in close contact with the surface of the transformer. When the flexible plate 704 expands outward, the expansion of the movable plate 2 703 will drive the elastic ring 801 to expand. When the elastic ring 801 expands, it will drive the T-shaped rod 803 through the rubber shaft 802, so that one end of the T-shaped rod 803 inside the threaded shaft 705 contacts the side wall of the hollow part of the threaded shaft 705, and then when the threaded shaft 705 rotates, the friction force can drive the T-shaped rod 803 to When the T-shaped rod 803 rotates, it will drive the rubber shaft 802 to rotate through friction. When the rubber shaft 802 rotates, it will be twisted and shortened. When the rubber shaft 802 shortens, the elastic ring 801 will pull the T-shaped rod 803 inward to form a pulling force on the surface of the transformer on four sides, thereby enhancing the supporting force of the transformer and forming a more stable supporting structure, which greatly enhances the clamping stability of the transformer, makes it difficult for it to move during the welding process, and further enhances the supporting force of the transformer.
