Description

Technical Field

[0001] This application relates to the technical field of transformer support frames, and in particular to a transformer support frame with an adjustable installation angle. Background Technology

[0002] The transformer support frame is a structural component used to support and secure the transformer, bearing its weight, including components such as the core and coils. It ensures the transformer remains stable during installation and operation, preventing deformation or displacement.

[0003] A search revealed Chinese Patent Publication No. CN 222483068 U, which discloses a multi-angle support transformer mounting bracket, including a clamp, a fixing lug, a load-bearing base, an adjusting support rod, and a protective frame, belonging to the field of transformer installation technology. This utility model uses the load-bearing base and adjusting support rod to fix and support the protective frame, while the transformer is installed inside the protective frame. The multi-angle support makes the mounting bracket more stable. Installing a leveling nut between the load-bearing base and the protective frame prevents the protective frame from tilting and causing the transformer inside the frame to shift, extending its service life. Fixing the transformer inside the protective frame before installing the protective frame at height reduces the operational difficulty of fixing the transformer in the air.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: traditional transformer support frames often have a fixed lateral installation angle, making it difficult to adapt to complex and ever-changing installation environments. This not only increases the difficulty of installation but may also affect the normal operation and service life of the transformer, and makes it inconvenient for operators to perform routine maintenance and repairs on the transformer.

The upper surface of the supporting rectangular plate is in sliding contact with the bottom of the middle sleeve plate.

[0011] Optionally, there are two plug-in plates, which are respectively set on the inner side of the two side frame plates. Both ends of the plug-in plates are provided with power grooves. The edge of the inner wall of the power groove is provided with a limiting triangle plate by rotating the rod.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. This utility model, by setting up components such as support columns, power inclined plates, threaded sliders, and lead screws, allows the support columns to rotate by driving the threaded sliders to move when the lead screw rotates. This enables the frame to adjust its angle 360° on the horizontal plane, avoiding adjacent cables or obstacles and achieving "zero-collision" installation. It solves the problem of secondary construction caused by the fixed installation direction of traditional frames, and adjusts the frame to the angle with the minimum windward side of the transformer (such as facing the side of the radiator towards the wind direction), thus reducing wind resistance load.

[0016] 2. When the transformer of this utility model needs to replace the high-voltage bushing or perform winding inspection, the maintenance surface can be turned to the operating space by rotating the frame laterally, without moving the transformer body. The lateral rotation adjustment avoids long-term stress concentration of the support components caused by installation angle deviation. It can accurately position in complex environments, quickly install in narrow spaces, and reduce cable bending loss. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses an adjustable transformer support frame. For example... Figure 1 and Figure 3As shown, the device includes two side frame plates 1. Each side frame plate 1 has two sets of fixing holes at both ends. Fixing bolt rods 6 are inserted into the fixing holes through nuts. The fixing bolt rods 6 have threads at both ends. A supporting rectangular plate 10 is fixedly installed on the inner side of the side frame plate 1 near the bottom. The upper surface of the supporting rectangular plate 10 slides in contact with the bottom of the middle sleeve plate 5. The side frame plates 1 are installed on the outside of the two utility poles through the fixing bolt rods 6. The supporting rectangular plate 10 supports the lower part of the middle sleeve plate 5 to prevent it from falling due to the weight of the transformer itself.

[0025] Please see Figure 3 Two plug-in plates 2 are fixedly installed on the inner side of the side frame plate 1 near the top. Each plug-in plate 2 is located on the inner side of one of the two side frame plates 1. Each plug-in plate 2 has a power groove 14 at both ends. A limiting triangle plate 15 is rotatably installed at the edge of the inner wall of the power groove 14 via a rotating rod. The limiting triangle plate 15 is a right triangle with an elastic circular plate 11 slidingly mounted on its inner right-angled side. The side of the elastic circular plate 11 away from the limiting triangle plate 15 is fixedly mounted on the inner wall of the power groove 14. The limiting triangle plate 15 is positioned within the inner elastic circular plate 11... The right-angled triangular limiting triangle 15 can always be in an outward state and can better engage with the middle sleeve 5. Both ends of the outer side of the elastic circular plate 11 are slidably provided with semi-circular push plates 12. The middle of the outer side of the semi-circular push plate 12 is fixedly provided with a telescopic slide rod 13. The end of the telescopic slide rod 13 away from the semi-circular push plate 12 is fixedly provided on both sides of the inner wall of the power groove 14. The semi-circular push plate 12 can promptly reset the elastic circular plate 11 after movement, making the elastic effect of the elastic circular plate 11 better, while preventing the elastic circular plate 11 from moving excessively inward under the action of the outer limiting triangle 15.

[0026] Please see Figure 2 and Figure 3 A middle sleeve plate 5 is slidably sleeved at one end of the plug-in plate 2 away from the side frame plate 1. The two sides of the middle of the middle sleeve plate 5 are fixedly provided with snap-fit ​​grooves 16. The inner wall of the snap-fit ​​grooves 16 is slidably connected to the two sides of the plug-in plate 2. Both ends of the middle sleeve plate 5 are provided with limit grooves 23. The inner wall of the limit grooves 23 is slidably connected to the outer side of the limit triangle plate 15. The snap-fit ​​grooves 16 in the middle of the middle sleeve plate 5 facilitate the sliding of the plug-in plate 2 inside the middle sleeve plate 5. The limit grooves 23 can snap-fit ​​with the limit triangle plate 15 to ensure that the middle sleeve plate 5 and the plug-in plate 2 are connected as a whole, and at the same time, it is convenient to adapt to transformers of more specifications.

[0027] Please see Figure 3 and Figure 4A rotating cylinder 9 is fixedly installed at the bottom of the middle sleeve plate 5. A bottom support plate 8 is fixedly installed at the top of the rotating cylinder 9. There are two bottom support plates 8, which are connected by screw threads. A bottom limiting circular plate 21 is fixedly installed at the top of the bottom support plate. A sliding groove is provided at the bottom of the inner wall of the bottom limiting circular plate 21, and a bottom rotating tube 7 is slidably installed on its inner wall. A top bearing plate 3 is fixedly installed at the top of the bottom rotating tube 7. Multiple through holes are provided on the upper surface of the top bearing plate 3. It can be fixed to the bottom of the transformer through the through holes to accommodate different specifications of fixing bolts and installation requirements. A bottom support block 4 is slidably installed at the bottom of the top bearing plate 3. The bottom of the bottom support block 4 is fixedly installed at the middle position of the top of the side frame plate 1. When the top bearing plate 3 rotates, it is supported by the bottom support block 4 to prevent it from tilting during rotation and to ensure more stable rotation. The top bearing plate 3 is set parallel to the side frame plate 1.

[0028] Please refer to it again. Figure 3 and Figure 4 A support column 20 is fixedly installed at the bottom of the top support plate 3. The bottom of the support column 20 is rotatably connected to the bottom of the inner wall of the bottom limiting circular plate 21. A power inclined plate 19 is fixedly installed at the middle of the outer side of the support column 20. A threaded slider 17 is rotatably sleeved at the end of the power inclined plate 19 away from the support column 20. A screw 18 is threadedly inserted into the middle of the threaded slider 17. A handle is fixedly installed at one end of the screw 18. One end of the handle extends to the outer side of the bottom rotating tube 7. The diameter of the handle is smaller than the thickness of the groove in the middle of the bottom rotating tube 7. The screw 18 is rotated by rotating the handle. When the screw 18 rotates, it prevents movement conflict with the middle of the bottom rotating tube 7. Vertical plates 22 are rotatably sleeved at both ends of the screw 18. The bottom of the vertical plate 22 is fixedly installed at the bottom of the inner wall of the bottom limiting circular plate 21.

[0029] The implementation principle of an adjustable installation angle transformer support frame according to an embodiment of this application is as follows: When installing the transformer, the two side frame plates 1 are fixedly connected to the external structure through the fixing bolt rods 6 and nuts, and the fixing round holes at both ends, thus building the frame foundation. The supporting rectangular plate 10 at the bottom of the inner side of the side frame plate 1 provides a sliding support surface for the middle sleeve plate 5, ensuring the stability of the subsequent adjustment process. The two plug-in plates 2 are inserted into the slot 16 inside the middle sleeve plate 5. At the same time, the limiting triangular plate 15 is inserted into the limiting slots 23 on both sides of the middle sleeve plate 5, so that the middle sleeve plate 5 and the two plug-in plates 2 on both sides are connected as a whole. The two bottom support plates 8 are connected as a whole through the nuts. The transformer body is installed above the top bearing plate 2. When the transformer needs to adjust the angle, the handle at one end of the lead screw 18 is rotated, and the lead screw 18 rotates accordingly. Since the lead screw 18 is threadedly connected to the threaded slider 17, the threaded slider 17 will move along the axial direction of the lead screw 18. The threaded slider 17 drives the power inclined plate 19 to move. The other end of the power inclined plate 19 is fixedly connected to the support column 20, so the support column 20 rotates accordingly. Because the top support plate 3 is fixedly connected to the top of the support column 20, the top support plate 3 rotates accordingly to achieve angle adjustment. During this process, the bottom rotating tube 7 slides in the groove of the bottom limiting circular plate 21 to assist the top support plate 3 to rotate smoothly.

[0030] Pulling the middle sleeve 5 allows it to slide on the plug-in plate 2, adjusting its position to accommodate transformers of different sizes or installation requirements. As the middle sleeve 5 slides, the inner walls of its end-positioning grooves 23 press against the right-angled edges of the positioning triangle 15, causing it to rotate around the rotating rod, compressing the elastic circular plate 11. When the middle sleeve 5 reaches the desired position, the positioning triangle 15, under the elastic force of the elastic circular plate 11, re-engages with the positioning groove 23, thus fixing the middle sleeve 5. Simultaneously, the semi-circular push plate 12 and the telescopic slide rod 13 assist the elastic circular plate 11, making the engagement between the positioning triangle 15 and the positioning groove 23 more stable.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
