Description

Technical Field

[0001] This invention belongs to the field of power equipment installation technology, and specifically relates to a lifting mechanism for power equipment installation. Background Technology

[0002] When installing transformers, a lifting mechanism is needed for transportation. Currently, lifting mechanisms on the market typically consist of a transport structure and a guide structure. The guide structure primarily adjusts the transport direction of the transformer, while the transport structure moves the transformer along the guide structure. While this type of lifting mechanism does achieve good transport efficiency, the transport method is relatively simple. The lifting structure lacks a limit mechanism for the transformer, making it prone to swaying during transport, which can easily cause the transformer to detach from the lifting mechanism. Furthermore, most lifting mechanisms on the market lack a transformer transport structure, making it difficult for workers to detach the transformer from the mechanism once it has been transported to the appropriate height, resulting in significant inconvenience during transport.

[0014] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1-6 The lifting mechanism for installing power equipment shown includes a top mounting plate 1. Sliding guide rails 5 are fixedly connected to the bottom of the top mounting plate 1 at the four corners. A fixed base 6 is fixedly connected to the lower part of the sliding guide rails 5. A limiting base structure 8 is distributed below the top mounting plate 1. A winding structure is detachably connected to the part of the top mounting plate 1 opposite to the limiting base structure 8. A transformer body 7 is detachably connected to the lower part of the winding structure. The limiting base structure 8 includes a connecting base plate 15. The top surface of the connecting base plate 15 is provided with connecting grooves 21 at equal intervals. A sliding plate 32 is slidably connected to the connecting base plate 15. A sliding wheel 20 is fixedly connected to the bottom surface of the sliding plate 32. The sliding wheel 20 slides with the connecting base plate 15 through the connecting grooves 21. A snap-fit ​​structure is detachably connected to the sliding plate 32. When the sliding plate 32 slides laterally on the connecting base plate 15 through the sliding wheel 20, the sliding plate 32 can drive the transformer body 7 to move. The snap-fit ​​structure includes a pressing block 17, through which a connecting screw 30 passes. The pressing block 17 is rotatably connected to the fixing block 29 via the connecting screw 30, which makes it easy for workers to press the bottom groove tube 13 through the pressing block 17.

[0016] Sliding blocks 16 are fixedly connected to both sides of the connecting base plate 15. The sliding blocks 16 slide with the sliding guide rail 5. The connecting base plate 15 supports the transformer body 7 through the sliding plate 32. The sliding guide rail 5 can limit the movement direction of the connecting base plate 15 through the sliding blocks 16.

[0017] A protective rod 22 is rotatably connected to the connecting base plate 15. The end of the protective rod 22 is provided with an insertion groove 23. A fixed handle 33 is fixedly connected to the protective rod 22. The protective rod 22 abuts against the sliding plate 32. The protective rod 22 can protect the sliding plate 32 and prevent the sliding plate 32 from separating from the connecting base plate 15.

[0018] A cylindrical cavity 25 is detachably connected to the inner wall of the connecting base plate 15. The outer wall of the cylindrical cavity 25 is provided with an external thread 26. The cylindrical cavity 25 is threadedly connected to the connecting base plate 15 through the external thread 26. A pressing block 24 is slidably connected inside the cylindrical cavity 25. A plug-in rod 19 is fixedly connected to the top surface of the pressing block 24. A compression spring 27 is fixedly connected to the bottom surface of the pressing block 24. The end of the compression spring 27 away from the pressing block 24 is fixedly connected to the bottom wall of the cylindrical cavity 25. The plug-in rod 19 is plugged into the plug-in circular groove 23. When the plug-in rod 19 is plugged into the plug-in circular groove 23, the protective rod 22 can protect the sliding plate 32. When the plug-in rod 19 is compressed, the plug-in rod 19 can drive the pressing block 24 to compress the compression spring 27. At this time, the repulsive force generated by the compression spring 27 can drive the plug-in rod 19 to be plugged into the inside of the plug-in circular groove 23.

[0019] The snap-fit ​​structure includes an electric slide rail 18 on the top surface of the sliding plate 32. The output end of the electric slide rail 18 is fixedly connected to a sliding seat 31. The sliding seat 31 is fixedly connected to a fixed block 29. A lever 28 is fixedly connected to the pressing block 17. The output end of the electric slide rail 18 can move the pressing block 17 to a different position through the sliding seat 31. When the pressing block 17 presses against the bottom groove tube 13, it can prevent the bottom groove tube 13 from separating from the sliding plate 32.

[0020] The winding structure includes a receiving roller 3 rotatably connected to the top mounting plate 1. A drive motor 2 is detachably connected to one side of the receiving roller 3. The output end of the drive motor 2 is detachably connected to the receiving roller 3. A receiving cable 4 is fixedly connected to the receiving roller 3. The lower end of the receiving cable 4 passes through the top mounting plate 1. The output shaft of the drive motor 2 can adjust the length of the receiving cable 4 through the receiving roller 3, thereby realizing the adjustment of the conveying height of the transformer body 7.

[0021] A connecting lug 14 is fixedly connected to the top surface of the transformer body 7. A through rod 9 passes through the connecting lug 14 on the top surface of the transformer body 7. A bottom groove tube 13 is fixedly connected to the bottom surface of the transformer body 7. The inner wall of the bottom groove tube 13 abuts against the pressing block 17. Fixed nuts 12 are threaded to both ends of the through rod 9. An inclined support rod 10 is fixedly connected to the through rod 9. Side ribs 11 are fixedly connected to both sides of the inclined support rod 10. The inclined support rod 10 is fixedly connected to the storage cable 4. The end of the side rib 11 facing away from the inclined support rod 10 is fixedly connected to the through rod 9. When the storage cable 4 is fixedly connected to the inclined support rod 10, the storage cable 4 can pull the transformer body 7.

[0022] Working principle: In actual use, the user places the fixed base 6 in a suitable position beforehand. Then, the operator starts the drive motor 2. The output end of the drive motor 2 can wind up the storage cable 4 through the storage roller 3. At this time, the storage cable 4 can be hoisted to the transformer body 7 through the through rod 9. The transformer body 7 can be pulled by the sliding plate 32 through the bottom groove tube 13. At this time, the sliding plate 32 will drive the connecting base plate 15 to move upward. When the connecting base plate 15 moves upward, the sliding block 16 on the connecting base plate 15 will slide relative to the sliding guide rail 5. This can prevent the transformer body 7 from shaking. When the transformer body 7 moves to the appropriate position, the operator's hand flips the protective rod 22 through the fixed handle 33. Then, the operator pulls the transformer body 7 laterally through the storage cable 4, which allows the sliding plate 32 to move laterally on the connecting base plate 15, thereby realizing the lateral transport of the transformer body 7 by the sliding plate 32. This makes it easier for the operator to separate the transformer body 7 from the mechanism. When the operator wants to separate the transformer body 7 from the sliding plate 32, the operator's hand rotates the pressure block 17 by the lever 28, which makes it easier for the operator to move the transformer body 7.
