Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1 See also Figures 1-8 , the present invention provides a technical solution: a transformer installation auxiliary suspension device and method, comprising a transformer body 1, wherein a suspension bracket 11 is provided at the upper end of the transformer body 1; An adjustment mechanism 2 is located between the transformer body 1 and the suspension bracket 11. The adjustment mechanism 2 includes a suspension column 3 fixedly connected to the upper end of the transformer body 1. A suspension screw 4 is provided inside the suspension column 3. The suspension column 3 is slidably connected to the suspension screw 4. The end of the suspension screw 4 away from the transformer body 1 is rotatably connected to the suspension bracket 11. A switching mechanism 5, the switching mechanism 5 is located outside the suspension column 3, and the switching mechanism 5 can switch the adjustment mechanism 2 to adjust the transformer body 1 horizontally and vertically; The present invention adjusts the lateral angle of the transformer body 1 through the adjustment mechanism 2, and can adjust the longitudinal angle of the transformer body 1 through the switching mechanism 5, so that the transformer body 1 is adjusted to a horizontal position, so that the internal components of the transformer body 1 are evenly stressed, and the vibration caused by uneven stress can be effectively reduced. At the same time, the transformer body 1 is adjusted to a horizontal position, which is convenient for connection and debugging with other electrical equipment.

[0019] The suspension column 3 includes a main adjustment column 31 fixedly connected to the upper end of the transformer body 1, a transverse adjustment column 32 is provided on one side of the main adjustment column 31, and a longitudinal adjustment column 33 is provided on the other side of the main adjustment column 31. A fixed column 34 is provided on the upper end of the transformer body 1. The main adjustment column 31, the transverse adjustment column 32, the longitudinal adjustment column 33 and the fixed column 34 are arranged in a square and are all fixedly connected to the upper end of the transformer body 1; The suspension screw 4 includes a suspension screw 1 41 disposed inside the main adjustment column 31, a suspension screw 2 42 disposed inside the transverse adjustment column 32, and a suspension screw 3 43 disposed inside the longitudinal adjustment column 33. After installing the suspension bracket 11, the fixing column 34 is fixedly connected to the suspension bracket 11. By adjusting the length of the suspension screw rod 1 41 and the suspension screw rod 2 42 at the same time, the lateral angle of the transformer body 1 can be adjusted. Similarly, by adjusting the length of the suspension screw rod 1 41 and the suspension screw rod 3 43 at the same time, the longitudinal angle of the transformer body 1 can be adjusted. When the transformer body 1 is in a horizontal state, the pressure of the transformer body 1 on the suspension bracket 11 is evenly distributed, avoiding the risk of bending or damage of the fixed parts of the suspension bracket 11 due to uneven force. At the same time, when the transformer body 1 is suspended horizontally, the gravity of the internal components of the transformer body 1 is evenly distributed, avoiding additional mechanical stress caused by tilting, thereby ensuring that the transformer can operate stably for a long time.

[0020] The switching mechanism 5 includes a switching groove 51 formed on the outer wall of the main adjustment column 31, a switching block 52 is slidably connected to the interior of the switching groove 51, a rotating ring 53 is fixedly connected to the outer wall of the switching block 52, the rotating ring 53 is located on the periphery of the main adjustment column 31 and is slidably connected to the main adjustment column 31, and a switching ring 54 is rotatably connected to the periphery of the main adjustment column 31, an annular groove 55 is formed on the inner wall of the switching ring 54, the rotating ring 53 is located inside the annular groove 55 and is slidably connected to the annular groove 55; The adjustment mechanism 2 includes a connecting rod 21 fixedly connected to the upper end of the switching ring 54, an adjusting ring 22 is provided on the periphery of the suspension screw 41, the adjusting ring 22 is threadedly connected to the suspension screw 41, and a limiting groove 23 is provided on the outer wall of the adjusting ring 22. The connecting rod 21 is located inside the limiting groove 23 and is slidably connected to the limiting groove 23. The outer periphery of the adjusting ring 22 is slidably connected to a fixing ring 24, and the outer periphery of the fixing ring 24 is sleeved with a belt 25; The outer periphery of the second suspension screw rod 42 is provided with a second adjustment ring 26, the second adjustment ring 26 is threadedly connected to the second suspension screw rod 42, the first belt 25 is sleeved on the outer periphery of the second adjustment ring 26, and a positioning groove 27 is provided at the bottom of the first adjustment ring 22; When adjusting the lateral angle of the transformer main body 1, the switching ring 54 is pushed upward, and the switching ring 54 drives the switching block 52 to slide inside the switching groove 51 through the rotating ring 53. At the same time, the connecting rod 21 at the upper end of the switching ring 54 passes through the limit groove 23 and is inserted into the positioning groove 27 provided at the bottom of the fixed ring 24. At this time, when the switching ring 54 is rotated, the switching ring 54 drives the adjusting ring 1 22 and the fixed ring 24 to rotate at the same time through the connecting rod 21. When the fixed ring 24 rotates, the adjusting ring 2 26 is driven to rotate synchronously through the belt 1 25. At this time, the rotation direction and angle of the adjusting ring 1 22 and the adjusting ring 2 26 are consistent. After the lateral angle adjustment of the transformer main body 1 is completed, the rotation is stopped. The operation process for adjusting the angle of the transformer main body 1 is simple. The angle adjustment can be completed by only pushing the switching ring 54 and rotating it, which reduces the steps and difficulty, makes it convenient for the operator to complete the operation quickly, and does not require complex tools, which not only reduces the operating cost, but also avoids the problems caused by improper use of tools, and is convenient for operation in various environments.

[0021] The outer wall of the main adjustment column 31 is fixedly connected to the limit ring 28, and the outer periphery of the main adjustment column 31 is rotatably connected to the adjustment ring 3 29. The inner wall of the adjustment ring 3 29 is provided with a through groove 210. The limit ring 28 is located inside the through groove 210 and is slidably connected to the through groove 210. The bottom of the switching ring 54 is fixedly connected to a plurality of teeth 1 211, and the upper end of the adjusting ring 3 29 is fixedly connected to a plurality of teeth 212, and the teeth 1 211 are meshed with the teeth 2 212; The outer periphery of the adjusting ring 3 29 is sleeved with the belt 213, and the outer periphery of the suspension screw 3 43 is provided with a driving ring 214, the driving ring 214 is threadedly connected to the suspension screw 3 43, and the belt 213 is sleeved on the outer periphery of the driving ring 214; After the lateral angle adjustment of the transformer main body 1 is completed, the switching ring 54 is pushed downward. At this time, the connecting rod 21 at the upper end of the switching ring 54 slides out of the positioning groove 27, but is still located inside the limit groove 23. When the switching ring 54 slides downward, the tooth 1 211 at the lower end of the switching ring 54 is engaged with the tooth 2 212 at the upper end of the adjustment ring 3 29. At this time, the switching ring 54 is rotated, and the switching ring 54 drives the drive ring 214 to rotate through the adjustment ring 3 29 and the belt 2 213. The drive ring 214 can drive the suspension screw 3 43 to rotate to complete the longitudinal angle adjustment of the transformer main body 1. The rotation of the suspension screw 2 42 is the same as the above-mentioned rotation, which will not be repeated. This adjustment method can adapt to the needs of the transformer main body 1 for lateral and longitudinal angle adjustment under different operating conditions and environments. In addition, the horizontal state of the transformer main body 1 is conducive to the uniform distribution of the electromagnetic field inside the transformer main body 1. When the transformer main body 1 is operating normally, the uniform electromagnetic field can improve the electromagnetic conversion efficiency of the transformer main body 1 and reduce energy loss. At the same time, it can also reduce electromagnetic interference and avoid adverse effects on surrounding electronic equipment and communication systems.

[0022] The working principle and usage steps of the present invention are as follows: After the suspension bracket 11 is installed, the fixing column 34 is fixedly connected to the suspension bracket 11, and the lengths of the suspension screw rod 1 41 and the suspension screw rod 2 42 are adjusted at the same time, so that the lateral angle of the transformer main body 1 can be adjusted. Similarly, the lengths of the suspension screw rod 1 41 and the suspension screw rod 3 43 can be adjusted at the same time, so that the longitudinal angle of the transformer main body 1 can be adjusted. When adjusting the lateral angle of the transformer main body 1, the switching ring 54 is pushed upward, and the switching ring 54 drives the switching block 52 to slide inside the switching groove 51 through the rotating ring 53. At the same time, the connecting rod 21 at the upper end of the switching ring 54 passes through the limit groove 23 and is inserted into the positioning groove 27 provided at the bottom of the fixing ring 24. At this time, when the switching ring 54 is rotated, the switching ring 54 drives the adjusting ring 1 22 and the fixing ring 24 to rotate at the same time through the connecting rod 21. When the fixed ring 24 rotates, the adjusting ring 26 is driven to rotate synchronously through the belt 1 25. At this time, the adjusting ring 1 22 and the adjusting ring 2 26 have the same rotation direction and angle. After the lateral angle adjustment of the transformer main body 1 is completed, the rotation is stopped. After the lateral angle adjustment of the transformer main body 1 is completed, the switching ring 54 is pushed downward. At this time, the connecting rod 21 at the upper end of the switching ring 54 slides out of the positioning groove 27, but is still located inside the limit groove 23. When the switching ring 54 slides downward, the tooth 1 211 at the lower end of the switching ring 54 is engaged with the tooth 2 212 at the upper end of the adjusting ring 3 29. At this time, the switching ring 54 is rotated. The switching ring 54 drives the drive ring 214 to rotate through the adjusting ring 3 29 and the belt 2 213. The drive ring 214 can drive the suspension screw rod 3 43 to rotate, thereby completing the longitudinal angle adjustment of the transformer main body 1.

[0023] Example 2 A transformer installation auxiliary suspension method includes the following steps: S1. Install the suspension bracket 11 above the transformer body 1 at the designated position. After installation, adjust the transformer body 1 to a horizontal position using the adjustment mechanism 2. S2. By rotating the switching ring 54 of the adjustment mechanism 2, the switching ring 54 drives the suspension screw to rotate through the adjustment ring 1 22, thereby achieving the purpose of adjusting the height of the suspension screw; S3. Connect the switching ring 54 to the second adjustment ring 26 through the switching mechanism 5. Rotating the switching ring 54 can simultaneously adjust the suspension screw 1 41 and the suspension screw 2 42, thereby adjusting the lateral angle of the transformer body 1. S4. Connect the switching ring 54 to the adjustment ring 3 29 through the switching mechanism 5. Rotating the switching ring 54 can simultaneously adjust the suspension screw 1 41 and the suspension screw 3 43, thereby adjusting the longitudinal angle of the transformer body 1.
