Description

A tooling for transformer assembly Technical Field

[0001] This invention relates to the field of transformer assembly, and more particularly to a tooling for transformer assembly. Background Technology

[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery, and other applications. Simply put, a dry-type transformer is one whose core and windings are not immersed in insulating oil. Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). With natural air cooling, the transformer can operate continuously at its rated capacity for extended periods. With forced air cooling, the transformer's output capacity can be increased by 50%. It is suitable for intermittent overload operation or emergency overload operation; however, because load losses and impedance voltage increases significantly under overload conditions, resulting in uneconomical operation, it should not be subjected to prolonged continuous overload operation.

[0003] When assembling existing dry-type transformers, workers need to remove the upper yoke before they can install high-voltage windings and other components. The upper yoke is composed of several silicon steel sheets, so workers need to remove them one by one, which is time-consuming and laborious. In addition, the silicon steel sheets can easily cut workers' arms when removing them.

[0004] Therefore, it is necessary to provide a new tooling for transformer assembly to solve the above-mentioned technical problems.

[0008] The base surface is provided with a first sliding groove, and a first bidirectional lead screw is movably arranged inside the first sliding groove through a bearing. The two ends of the first bidirectional lead screw pass through the bottom of the two uprights respectively, and the bottom of the uprights is slidably connected to the first sliding groove.

[0009] Each of the two standing bases has a mounting bracket fixed to its opposite side, and a clamp is mounted on the mounting bracket. The clamp and the base are located on the same plane.

[0010] In a preferred embodiment, the support assembly includes a top seat, two support shafts symmetrically arranged above the top seat, an arc-shaped support rod fixed on each of the two support shafts, a second sliding groove on each of the two arc-shaped support rods, a load-bearing plate slidably arranged between the two second sliding grooves, and a first lifting ring fixed at both ends of the load-bearing plate.

[0011] In a preferred embodiment, worm gears are mounted on both support shafts, and two limiting seats are fixed at intervals on the top seat. A worm is movably arranged between the two limiting seats via a bearing, and the worm meshes with the two worm gears.

[0012] In a preferred embodiment, a crank is mounted on the end of the worm gear away from the load-bearing plate.

[0013] In a preferred embodiment, the system further includes a connecting frame with four suspension ropes spaced apart at the bottom. The bottom of each suspension rope is fixed with a hook, and a connecting rod is fixed to the top of the connecting frame. A second lifting ring is fixed to the top of the connecting rod.

[0014] In a preferred embodiment, the load-bearing plate has a through groove, and a second bidirectional lead screw is movably arranged inside the through groove via a bearing. Two adjusting sliders are symmetrically arranged inside the through groove, and a slot is provided at the top of each adjusting slider. The second bidirectional lead screw passes through the two adjusting sliders, and the second bidirectional lead screw is threadedly connected to the adjusting sliders.

[0015] A stabilizing plate is provided above the load-bearing plate, and a locking block is installed at the bottom of the stabilizing plate, and the locking block is engaged with the locking slot.

[0016] In a preferred embodiment, a mounting base is fixed inside the through groove, a connecting shaft is provided through the mounting base, a hexagonal block is fixed at the top of the connecting shaft, a first bevel gear is fixed at the bottom of the connecting shaft, a second bevel gear is mounted on the second bidirectional lead screw, and the second bevel gear meshes with the first bevel gear.

[0017] In a preferred embodiment, a first sliding rod is provided through one of the uprights, and a second sliding rod is provided through the other upright;

[0018] Two measuring tapes are installed at intervals on the first sliding rod, and a hook is fixed to the stretching end of the measuring tape. Two fixing blocks are fixed at intervals on the second sliding rod, and a hanging ring is fixed on the fixing block. The hanging ring and the measuring tape are located in the same plane.

[0019] In a preferred embodiment, both the first slide rod and the second slide rod are slidably connected to the stand, and the surfaces of both the first slide rod and the second slide rod are roughened.

[0020] In a preferred embodiment, a motor is mounted on one side of the base, and the output end of the motor is connected to the first bidirectional lead screw via a coupling.

[0021] Beneficial effects of this invention:

[0022] 1. When using this assembly fixture, workers can move the unassembled transformer mounting base and the components above it onto the roller conveyor frame using a gantry crane. Before assembling the transformer mounting base, workers can start the motor to move the two clamping plates closer together to limit the movement of the transformer mounting base on both sides, preventing the transformer mounting base from shaking during assembly.

[0023] 2. To save time for workers dismantling the upper yoke, workers can rotate the crank to drive the worm gear. Under the action of the support shaft, the two arc-shaped support rods move to both sides of the iron core column. At this time, workers can slide the two load-bearing plates along the second slide groove between the two arc-shaped support rods. After the movement is completed, the four hooks can be hung on the first lifting ring, and then the second lifting ring can be connected to the hook of the gantry crane. At this time, starting the gantry crane can drive the load-bearing plates to the position in contact with the upper yoke.

[0024] 3. To prevent the upper yoke from shaking and falling during movement, the worker can use a wrench to turn the hexagonal block. When the hexagonal block rotates, it will drive the connecting shaft to rotate. Under the transmission action of the first bevel gear and the second bevel gear, the second double-acting screw will rotate and drive the adjusting slider to slide along the through groove. Finally, it will drive the two stabilizing plates to move closer to each other and fix the upper yoke.

[0025] 4. When installing resin pads and high-voltage windings, when placing resin pads on one side of the core column, workers can pull the hook to unfold the measuring tape on one side of the high-voltage winding. At this time, the installation position of the resin pad can be located according to the scale on the measuring tape, avoiding incorrect installation of the resin pad, which would require a lot of time to adjust the position of the resin pad later. When it is necessary to place resin pads on the other side of the core column, simply slide the first and second sliding rods to the other side, reducing the space occupied.

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0037] Please refer to Figures 1, 2, 3, 4, 5, 6, 7, 8, and 9. Figure 1 is a three-dimensional view of the overall structure of the transformer assembly fixture provided by this invention; Figure 2 is an enlarged structural schematic diagram of A shown in Figure 1; Figure 3 is a structural schematic diagram of the support component provided by this invention; Figure 4 is a structural schematic diagram of the connecting frame provided by this invention; Figure 5 is a structural schematic diagram of the load-bearing plate provided by this invention; Figure 6 is an enlarged structural schematic diagram of B shown in Figure 5; Figure 7 is a two-dimensional view of the overall structure of the transformer assembly fixture provided by this invention; Figure 8 is a top view of the overall structure of the transformer assembly fixture provided by this invention; and Figure 9 is a structural schematic diagram of the second sliding rod provided by this invention.

[0038] In the specific implementation process, as shown in Figures 1-9, the system includes a base 1, a gantry crane is set directly above the base 1 to transport the accessories to be installed, a roller conveyor frame 2 is installed on the base 1, two transformer mounting bases 3 are placed at intervals on the roller conveyor frame 2, and uprights 4 are symmetrically arranged on both sides of the roller conveyor frame 2, with support components on the top of the uprights 4.

[0039] The base 1 has a first sliding groove 5 on its surface. A first double-acting screw 6 is movably mounted inside the first sliding groove 5 via bearings. The two ends of the first double-acting screw 6 pass through the bottom of the two uprights 4 respectively, and the bottom of the uprights 4 is slidably connected to the first sliding groove 5. A mounting bracket 7 is fixed on the opposite side of the two uprights 4. A clamping plate 8 is mounted on the mounting bracket 7. The clamping plate 8 is located on the same plane as the base 3. A motor 41 is mounted on one side of the base 4. The output end of the motor 41 is connected to the first double-acting screw 6 via a coupling. Before the transformer mounting base 3 is moved onto the base 1 for assembly, the operator can start the motor 41 to drive the first double-acting screw 6 to rotate. Driven by the first double-acting screw 6, the two uprights 4 will move closer to each other along the first sliding groove 5. When they move closer to each other, the two clamping plates 8 will move closer to each other to limit the movement of the transformer mounting base 3 on both sides, preventing the transformer mounting base 3 from shaking during assembly.

[0040] The support assembly includes a top seat 9, with two symmetrically arranged support shafts 10 above the top seat 9. Each support shaft 10 has an arc-shaped support rod 11 fixed to it. Each arc-shaped support rod 11 has a second sliding groove 12. A load-bearing plate 13 is slidably arranged between the two second sliding grooves 12. Both ends of the load-bearing plate 13 are fixed with first lifting rings 14. Worm gears 15 are installed on each of the two support shafts 10. Two limiting seats 16 are fixed at intervals on the top seat 9. A worm gear 17 is movably arranged between the two limiting seats 16 via a bearing. The worm gear 17 meshes with the two worm gears 15. A crank 18 is installed at the end of the worm gear 17 away from the load-bearing plate 13 for easy rotation by the operator. The assembly also includes a connecting frame 19. Four lifting ropes 20 are installed at intervals at the bottom of the connecting frame 19. Hooks 21 are fixed to the bottom of each rope 20. A connecting rod 22 is fixed to the top of the connecting frame 19. A second lifting ring 22 is fixed to the top of the connecting rod 22. 3. To save time for workers to dismantle the upper yoke, workers can rotate the crank 18 to drive the worm gear 17 to rotate. Under the transmission action of the worm gear 17, the two worm wheels 15 rotate simultaneously, driving the support shaft 10 to rotate as well. Under the action of the support shaft 10, the two arc-shaped support rods 11 move to both sides of the iron core column 44. At this time, workers can slide the two load-bearing plates 13 along the second slide groove 12 between the two arc-shaped support rods 11. After the movement is completed, the four hooks 21 can be hung on the first lifting ring 14 respectively, and then the second lifting ring 23 can be connected to the hook of the gantry crane. At this time, starting the gantry crane can drive the load-bearing plates 13 to the position where they contact the upper yoke.

[0041] A through groove 24 is provided on the load-bearing plate 13. A second bidirectional lead screw 25 is movably mounted inside the through groove 24 via a bearing. Two adjusting sliders 26 are symmetrically arranged inside the through groove 24. A slot 27 is provided on the top of the adjusting sliders 26. The second bidirectional lead screw 25 passes through the two adjusting sliders 26 and is threadedly connected to the adjusting sliders 26. A stabilizing plate 28 is provided above the load-bearing plate 13. A locking block 29 is installed at the bottom of the stabilizing plate 28 and is engaged with the slot 27. A mounting base 30 is fixed inside the through groove 24. A connecting shaft 31 is provided through the mounting base 30. A hexagonal block 32 is fixed at the top of the connecting shaft 31 and a first bevel gear 33 is fixed at the bottom of the connecting shaft 31. A second bevel gear 34 is mounted on the second bidirectional lead screw 25 and meshes with the first bevel gear 33.

[0042] To prevent the upper yoke from wobbling and falling during movement, workers can use a wrench to turn the hexagonal block 32. As the hexagonal block 32 rotates, it drives the connecting shaft 31 to rotate. Under the transmission action of the first bevel gear 33 and the second bevel gear 34, the second double-acting screw 25 rotates, causing the adjusting slider 26 to slide along the through groove 24. Finally, it drives the two stabilizing plates 28 to move closer together and fix the upper yoke. At this point, the gantry crane can be started to lift the entire upper yoke upwards and move it to another area.

[0043] One of the supports 4 has a first sliding rod 36 running through it, and the other support 4 has a second sliding rod 37 running through it. Two measuring tapes 38 are installed at intervals on the first sliding rod 36, and hooks 39 are fixed to the extended ends of the measuring tapes 38. Two fixing blocks 35 are fixed at intervals on the second sliding rod 37, and hanging rings 40 are fixed to the fixing blocks 35. The hanging rings 40 and the measuring tapes 38 are located in the same plane. Both the first sliding rod 36 and the second sliding rod 37 are slidably connected to the supports 4. The surfaces of both the first sliding rod 36 and the second sliding rod 37 are roughened, requiring workers to apply a certain amount of force to move them. When the slide bar 37 moves, during the installation of the resin pad 43 and the high-voltage winding 42, when placing the resin pad 43 on one side of the iron core column 44, the worker can pull the hook 39 to unfold the tape measure 38 on one side of the high-voltage winding 42. At this time, the installation position of the resin pad 43 can be located according to the scale on the tape measure 38, avoiding the need for a lot of time to adjust the position of the resin pad 43 later due to incorrect installation. When it is necessary to place the resin pad 43 on the other side of the iron core column 44, it is only necessary to slide the first slide bar 36 and the second slide bar 37 to the other side, which reduces the space occupied.

[0044] Working principle of the invention: In order to save the time of workers dismantling the upper yoke, workers can rotate the crank 18 to drive the worm gear 17 to rotate. Under the transmission action of the worm gear 17, the two worm wheels 15 rotate simultaneously, driving the support shaft 10 to rotate as well. Under the action of the support shaft 10, the two arc-shaped support rods 11 move to both sides of the iron core column 44. At this time, workers can slide the two load-bearing plates 13 along the second slide groove 12 into the space between the two arc-shaped support rods 11. After the movement is completed, the four hooks 21 can be hung on the first lifting ring 14 respectively, and then the second lifting ring 23 is connected to the hook of the gantry crane. At this time, starting the gantry crane can drive the load-bearing plates 13 to the position where they contact the upper yoke.

[0045] To prevent the upper yoke from shaking and falling during movement, the operator can use a wrench to turn the hexagonal block 32. When the hexagonal block 32 rotates, it will drive the connecting shaft 31 to rotate. Under the transmission action of the first bevel gear 33 and the second bevel gear 34, the second double-acting screw 25 rotates and drives the adjusting slider 26 to slide along the through groove 24, which will eventually drive the two stabilizing plates 28 to move closer to each other and fix the upper yoke.

[0046] Before the transformer mounting base 3 is moved onto the base 1 for assembly, the operator can start the motor 41 to drive the first double-acting screw 6 to rotate. Under the drive of the first double-acting screw 6, the two uprights 4 will move closer to each other along the first slide groove 5. When they move closer to each other, the two clamps 8 will move closer to each other to limit the two sides of the transformer mounting base 3, so as to prevent the transformer mounting base 3 from shaking during assembly.

[0047] When installing the resin pad 43 and the high-voltage winding 42, when placing the resin pad 43 on one side of the core column 44, the worker can pull the hook 39 to unfold the tape measure 38 on one side of the high-voltage winding 42. At this time, the installation position of the resin pad 43 can be located according to the scale on the tape measure 38, avoiding the need for a lot of time to adjust the position of the resin pad 43 later due to incorrect installation. When it is necessary to place the resin pad 43 on the other side of the core column 44, it is only necessary to slide the first slide rod 36 and the second slide rod 37 to the other side, which reduces the space occupied.
