Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a transformer oil tank installation structure. Background Technology

[0002] A transformer consists of an iron core, windings, insulation structure, oil tank, and cooling system. The transformer casing can accommodate the iron core and windings and also serve as an oil tank.

[0003] When installing a transformer oil tank, due to the large overall weight of the transformer, it is not convenient to center the transformer oil tank when installing it with hoisting equipment. It is also difficult to accurately adjust the installation position of the transformer oil tank manually. During installation, it is only supported by two mounting brackets at the bottom of the transformer oil tank, which has limited support force. In addition, traditional transformer oil tanks are mostly directly welded, making them difficult to disassemble and assemble. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a transformer tank installation structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A transformer tank mounting structure includes two columns and a transformer tank. A mounting plate is fixedly connected between the bottoms of the two columns. A mounting block is fixedly installed in the middle of the mounting plate. The mounting block has first sliding grooves parallel to the direction of the mounting plate at its four corners. Two second sliding grooves perpendicular to the first sliding grooves are opened in the middle of the mounting block. A first slider is slidably connected in the first sliding groove. A support block is fixedly connected to the top of every two first sliders parallel to the direction of the second sliding groove. A second slider is slidably connected in the second sliding groove. A movable block is fixedly connected to the top of the second slider. Two movable blocks are threaded to the two ends of a bidirectional screw. A fixing seat is fixedly installed on the opposite face of the two support blocks.

[0007] Preferably, the mounting plate has several hollow grooves evenly distributed on both sides, and the mounting block also has a hollow groove in the middle.

[0008] Preferably, the transformer box shell is an oil tank, and two C-shaped mounting brackets are symmetrically arranged at the bottom of the transformer box. Positioning grooves are opened on both sides of the mounting brackets, and bolt holes are opened on the mounting brackets above and below the positioning grooves.

[0009] Preferably, the support block is fixedly connected to a connecting lug on the side wall near the column, and the connecting lug is adapted to the positioning groove.

[0010] Preferably, the connecting ear has a through hole, the diameter of which is larger than the diameter of the bolt hole.

[0011] Preferably, a square block is fixedly connected to one end of the bidirectional screw, the square block is slidably connected to the rotating block through a square hole, and a handle is fixedly connected to one side of the rotating block.

[0012] Preferably, a first connecting rod and a second connecting rod are rotatably connected to one side of the fixed base, and the ends of the first connecting rod and the second connecting rod are respectively rotatably connected to the side walls of the two moving blocks.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by setting up support blocks, allows for the installation of heavy transformer boxes on top of the mounting blocks using external hoisting equipment. Rotating the bidirectional screw pushes two moving blocks closer together, causing the two fixed seats and support blocks to move further apart. This allows the two support blocks to abut against the opposite surfaces of the two mounting frames, enabling the support blocks to push the mounting frames and transformer boxes, thus achieving fine-tuning and centering of the transformer box. Compared to traditional manual pushing or frequent fine-tuning with hoisting equipment, this method is faster and easier, allowing for rapid centering and positioning. After installation, the support blocks themselves can also serve as supports for the transformer box, improving the support effect of the mounting frames. Furthermore, the bidirectional screw and moving blocks have a self-locking effect, preventing them from moving on their own and ensuring safety.

[0015] This utility model features a connecting ear that works with a positioning slot to position the transformer box. Once the connecting ear is inserted into the positioning slot, the mounting bracket can be determined to be in the center of the mounting block, thus achieving rapid centering. The through hole, combined with the two bolt holes at the top and bottom, is used to lock the mounting bracket, and it is also easy to disassemble when replacement or maintenance is needed in the future.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A transformer tank mounting structure includes two columns 1 and a transformer tank 5. A mounting plate 2 is fixedly connected between the bottoms of the two columns 1. A mounting block 4 is fixedly installed in the middle of the mounting plate 2. First grooves 9 parallel to the direction of the mounting plate 2 are formed at the four corners of the mounting block 4. Two second grooves 10 perpendicular to the first grooves 9 are formed in the middle of the mounting block 4. First sliders 11 are slidably connected within the first grooves 9. A support block 13 is fixedly connected to the top of every two first sliders 11 parallel to the direction of the second grooves 10. Second sliders 12 are slidably connected within the second grooves 10. A moving block 16 is fixedly connected to the top of the second slider 12. Two moving blocks 16 are threadedly connected to both ends of a bidirectional screw 17. Fixed seats 24 are fixedly installed on the opposite faces of the two support blocks 13. The column 1 is used to fix the mounting plate 2 and bear the weight of the transformer box 5. The width of the mounting block 4 is greater than that of the mounting plate 2, which facilitates the positioning and placement of the mounting frame 6. When using external hoisting equipment to hoist the heavy transformer box 5 above the mounting block 4, the two moving blocks 16 can be pushed closer to each other by rotating the bidirectional screw 17, so that the two fixed seats 24 and the support block 13 are moved away from each other. This allows the two support blocks 13 to abut against the opposite surfaces of the two mounting frames 6 respectively, so that the support blocks 13 can push the mounting frame 6 and the transformer box 5 to achieve fine-tuning and centering of the transformer box 5. Compared with the traditional manual pushing or frequent fine-tuning by hoisting equipment, the adjustment speed is faster and the adjustment difficulty is smaller. It can achieve rapid centering and positioning. After installation, the support block 13 itself can also serve as a support for the transformer box 5, improving the support effect of the mounting frame 6.

[0024] As a technical optimization of this utility model, several hollow grooves 3 are evenly opened on both sides of the mounting plate 2, and a hollow groove 3 is also opened in the middle of the mounting block 4. The hollow grooves 3 are used for ventilation.

[0025] As a technical optimization of this utility model, the outer shell of the transformer box 5 is an oil tank. Two C-shaped mounting brackets 6 are symmetrically arranged at the bottom of the transformer box 5. Positioning grooves 7 are opened on both sides of the mounting brackets 6. Bolt holes 8 are opened on the mounting brackets 6 above and below the positioning grooves 7. The mounting brackets 6 are used to support and elevate the transformer box 5. After positioning, bolts are used to lock the mounting brackets 6 and the support block 13 through the bolt holes 8 and the through holes 15.

[0026] As a technical optimization of this utility model, a connecting ear 14 is fixedly connected to the side wall of the support block 13 near the column 1. The connecting ear 14 is adapted to the positioning groove 7. The connecting ear 14 is used to cooperate with the positioning groove 7 to position the transformer box 5. After the connecting ear 14 is inserted into the positioning groove 7, it can be determined that the mounting frame 6 is in the center position of the mounting block 4, thus achieving rapid centering.

[0027] As a technical optimization of this utility model, a through hole 15 is provided on the connecting ear 14, the diameter of which is larger than the diameter of the bolt hole 8. The through hole 15, together with the two bolt holes 8 above and below, is used to lock the mounting bracket 6. In actual use, shims can be added to the top and bottom of the through hole 15 to ensure a tight connection of the bolts.

[0028] As a technical optimization of this utility model, a square block 18 is fixedly connected to one end of the bidirectional screw 17. The square block 18 is slidably connected to the rotating block 19 through a square hole 20. A handle 21 is fixedly connected to one side of the rotating block 19. The rotating block 19 and the bidirectional screw 17 are connected through the square block 18 and the square hole 20. They are connected during use and can be directly removed after use to prevent accidental contact by unauthorized personnel from affecting the stability of the transformer box 5.

[0029] As a technical optimization of this utility model, a first connecting rod 22 and a second connecting rod 23 are rotatably connected to one side of the fixed base 24. The ends of the first connecting rod 22 and the second connecting rod 23 are respectively rotatably connected to the side walls of the two moving blocks 16. Through the transmission of the first connecting rod 22 and the second connecting rod 23, the two fixed bases 24 and the support block 13 can approach or move away from each other, thereby realizing the pushing, centering and positioning function of the mounting frame 6. Furthermore, the bidirectional screw 17 and the moving block 16 themselves have a self-locking effect and will not move on their own, ensuring safety.

[0030] In use, this utility model employs external hoisting equipment to lift the transformer box 5 to be installed above the mounting plate 2. After adjusting its position, the transformer box 5 is moved above the mounting block 4. At this point, the external hoisting equipment is lowered so that the bottom end of the mounting bracket 6 at the bottom of the transformer box 5 contacts the top end of the mounting block 4, while the external hoisting equipment remains under load. The square hole 20 of the rotating block 19 is then connected to the square block 18. The handle 21 is manually turned to rotate the rotating block 19 and the bidirectional screw 17. When the bidirectional screw 17 rotates, it pushes the two moving blocks 16 and the two second sliders 12 along the second slide groove 10 in opposite directions. As the two moving blocks 16 approach each other, the first connecting rod 22 and the second connecting rod 23 rotate and approach each other, thereby pushing the two fixed seats 24 away from each other. This pushes the two support blocks 13 away from each other along the first sliding groove 9 and synchronously pushes the mounting frame 6 to move, realizing the fine adjustment and centering of the transformer box 5. Finally, the four connecting ears 14 are respectively connected to the four positioning grooves 7 of the two mounting frames 6. At this time, bolts can be used to lock them by sequentially connecting them to the bolt holes 8 and through holes 15. The external hoisting equipment is removed and the rotating block 19 is taken off to complete the installation.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
