Description

Technical Field

[0001] This invention belongs to the technical field of transformer maintenance platforms, and more specifically, it relates to a maintenance platform for high-altitude transformer maintenance. Background Technology

[0002] Transformers are one of the most important pieces of electrical equipment in a power system. Regular maintenance is necessary to ensure their safe operation and extend their service life. A transformer maintenance platform refers to a platform that provides support and convenience for transformer maintenance work. However, the existing transformer maintenance platform still has the following shortcomings in use: 1. Most existing transformer maintenance platforms are not equipped with power failure protection devices during use. When the hydraulic cylinder is suddenly powered off due to special factors, the maintenance platform is prone to sudden drop, which can easily cause danger. 2. When using existing maintenance platforms, most of them use a suspension method to retrieve items for maintenance. However, traditional equipment requires maintenance personnel to stand on the edge of the platform and lean out to lift items, which makes it difficult to guarantee the safety of the operation.

[0003] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a maintenance platform for high-altitude transformers, in order to achieve a more practical purpose. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a maintenance platform for high-altitude transformers. This addresses the issues of existing transformer maintenance platforms often lacking power outage protection devices, leading to sudden power failures in hydraulic cylinders due to unforeseen circumstances, which can cause the platform to fall and pose a safety hazard. Furthermore, existing maintenance platforms often employ suspension methods for retrieving items, requiring operators to lean out from the platform's edge, compromising operational safety.

[0005] A maintenance platform for inspecting high-altitude transformers includes a base, a central column fixedly installed at the center of the upper end of the base, a first sliding groove opened inside the central column, and ladders symmetrically fixedly installed at the upper end of the base, with inner columns slidably installed inside each of the two ladders. The central column is equipped with a hydraulic cylinder, which is fixedly connected to the base. An electric telescopic rod is connected to the output end of the hydraulic cylinder, and a lifting platform is fixedly installed at the upper end of the electric telescopic rod. Both inner columns are fixedly connected to the lifting platform. An adjustment mechanism is provided on both sides of the central column; The adjustment mechanism includes two side blocks, both of which are fixedly connected to the central column, and a fixing cylinder is fixedly installed on the upper end of each of the two side blocks.

[0006] Preferably, a second sliding groove is provided on both side walls of the two fixed cylinders; The two fixed cylinders each have a third sliding groove on their other two side walls.

[0007] Preferably, screws are fixedly installed on the opposite side walls of the two fixed cylinders; Both screws are threaded with threaded rings.

[0008] Preferably, an inner rod is slidably installed inside the two first grooves, and the two ends of the inner rod are respectively slidably sleeved on the two screws; The lower end of the lifting platform is symmetrically fixedly equipped with sliding columns. The two sliding columns are slidably installed in two fixed cylinders, and both sliding columns are fixedly connected to the inner rod.

[0009] Preferably, sliders are symmetrically fixedly installed on both side walls of the two sliding columns; The two sets of sliders are respectively slidably embedded in the two sets of third sliding grooves.

[0010] Preferably, a placement slot is provided at the upper end of the lifting platform; The placement groove contains a placement strip that is slidably installed inside.

[0011] Preferably, fixing blocks are symmetrically fixedly installed on both sides of the lifting platform, and fixing columns are fixedly installed inside both sets of fixing blocks; Each of the two lifting platforms has slots on its two side walls, and each of the two slots has a connecting groove in its inner wall.

[0012] Preferably, each of the two fixed columns is fitted with a sleeve, and each of the two sleeves has symmetrically formed grooves on its sidewall; Both of the sleeves are fixedly equipped with a first protective plate at their upper ends.

[0013] Preferably, limit turntables are symmetrically installed on the upper ends of the two first protective plates, and springs are symmetrically fixed in the inner walls of the two slots; Each of the two sets of springs is fixedly equipped with a retaining bar, and the two retaining bars are slidably embedded in two slots respectively.

[0014] Preferably, a connecting block is fixedly installed at the upper end of each of the two card strips, and the two connecting blocks are slidably disposed in the two communicating grooves respectively; Each of the two first protective plates has symmetrically spaced grooves at opposite ends, and a second protective plate is inserted into each of the two sets of spacers.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a hydraulic cylinder, an electric telescopic rod, a lifting platform, a fixed cylinder, a third slide groove, sliding columns, and sliders are provided. Under the action of the hydraulic cylinder, the electric telescopic rod will extend and retract accordingly. At this time, the electric telescopic rod will drive the lifting platform to rise. As the lifting platform moves, it will drive the two sliding columns to slide upward inside the two fixed cylinders. Then, the two sliding columns will drive the two sets of sliders to slide inside the two sets of third slide grooves, thereby effectively ensuring the stability of the equipment during lifting and lowering, and facilitating the lifting of the equipment to any height. In this invention, a screw, threaded rings, and an inner rod are provided. The rotation of the two threaded rings will drive the inner rod to complete the limiting operation. Since the threaded rings are threadedly connected to the screw, even if the equipment stops working due to an emergency, the two threaded rings will limit the equipment, effectively preventing it from falling suddenly, and thus effectively protecting the personal safety of the maintenance personnel. In this invention, by providing a placement slot and a placement bar, the placement bar can be pulled out from the placement slot. At this time, the object can be lifted through the two placement slots, which effectively avoids the need for maintenance personnel to stand on the edge of the platform and lean out to lift objects when using traditional equipment, and further ensures the safety of the equipment. In this invention, by providing a limiting turntable, a spring, a limiting groove, and a second protective plate, the two first protective plates can be kept in a vertical state in the initial state. Then, the two second protective plates can be inserted into the two sets of limiting grooves respectively. At this time, the two limiting turntables can be rotated on the two first protective plates to limit the two second protective plates. This allows the equipment to form effective protection for the maintenance personnel during use, enhancing the protective effect of the equipment on the maintenance personnel. In this invention, by providing sleeves, slots, springs, connecting blocks, and second protective plates, when the two sleeves are rotated 180° on the lifting platform, the two connecting blocks are released. At this time, the two sets of springs will restore their elasticity and thus complete the locking of the sleeves again. Then, step three can be repeated to complete the installation of the two second protective plates. At this time, the two sets of first and second protective plates will combine to complete the shielding of the equipment, thereby improving the protection effect of the equipment itself and extending the service life of the equipment.

[0018] This application provides a maintenance platform for high-altitude transformers, effectively solving the problems of existing transformer maintenance platforms, most of which lack power failure protection devices. These platforms are prone to sudden drops and potential hazards when hydraulic cylinders experience sudden power outages due to unforeseen circumstances. Furthermore, existing platforms often use suspension methods to lift items, requiring operators to lean out from the platform edge, compromising safety. The application addresses these issues by providing a platform with screws and threads. The inner rod and the inner ring are controlled by the rotation of the two threaded rings, which limit the movement of the inner rod. Since the threaded rings are threaded onto the screw, even if the equipment stops operating suddenly, the two threaded rings will still limit the movement of the equipment, effectively preventing it from falling suddenly and thus ensuring the safety of the maintenance personnel. In addition, the placement slots and placement bars can be installed so that the placement bars can be pulled out from the placement slots. At this time, the objects can be lifted through the two placement slots, which effectively avoids the need for maintenance personnel to stand on the edge of the platform and lean out to lift objects, as is the case with traditional equipment, further ensuring the safety of the equipment.

[0019] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0020] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the technical solution in this application embodiment effectively solves the problems that most existing transformer maintenance platforms do not have power failure protection devices during use. When the hydraulic cylinder is suddenly powered off due to special factors, the maintenance platform is prone to sudden drop, which can easily cause danger. Also, when existing maintenance platforms need to retrieve maintenance items, they mostly use a suspension method. However, traditional equipment requires the maintenance personnel to stand on the edge of the platform and lean out to lift the items, which makes it difficult to guarantee the safety of the operation. The overall idea is as follows: This invention provides a maintenance platform for high-altitude transformer maintenance, including a base 11. A central column 12 is fixedly installed at the center of the upper end of the base 11. A first sliding groove 13 is opened inside the central column 12. Climbing ladders 14 are symmetrically fixedly installed at the upper end of the base 11. Inner columns 15 are slidably installed inside the two climbing ladders 14. The central column 12 is equipped with a hydraulic cylinder 16, which is fixedly connected to the base 11. An electric telescopic rod 17 is connected to the output end of the hydraulic cylinder 16, and a lifting platform 18 is fixedly installed on the upper end of the electric telescopic rod 17. Both inner columns 15 are fixedly connected to the lifting platform 18. Adjustment mechanisms are provided on both sides of the central column 12; The adjusting mechanism includes side blocks 21, both of which are fixedly connected to the central column 12. A fixed cylinder 22 is fixedly installed on the upper end of each side block 21. Second sliding grooves 23 are formed on both side walls of the two fixed cylinders 22, and third sliding grooves 24 are formed on the other two side walls of the two fixed cylinders 22. A screw 25 is fixedly installed on the opposite side wall of each of the two fixed cylinders 22. Threaded rings 26 are threaded onto each of the two screws 25. Inner rods 2 are slidably installed inside the two first sliding grooves 13. 7. The inner rod 27 is slidably sleeved on two screw rods 25 at both ends. Sliding columns 28 are symmetrically fixedly installed at the lower end of the lifting platform 18. The two sliding columns 28 are slidably housed within two fixed cylinders 22. Both sliding columns 28 are fixedly connected to the inner rod 27. Sliding blocks 29 are symmetrically fixedly installed on the side walls of both sliding columns 28. The two sets of sliding blocks 29 are slidably housed within two sets of third sliding grooves 24. In use, the base 11 can be moved to the designated position first, and then the operator can complete the process via the two ladders 14. When the equipment is in the climbing position, the hydraulic cylinder 16 can be activated. Under the action of the hydraulic cylinder 16, the electric telescopic rod 17 will extend and retract. The electric telescopic rod 17 will then lift the lifting platform 18 upward. As the lifting platform 18 moves, the two sliding columns 28 will slide upward inside the two fixed cylinders 22. The two sliding columns 28 will then drive the two sets of sliders 29 to slide inside the two sets of third sliding grooves 24, thus effectively ensuring the stability of the equipment during lifting. The two sliding columns 28 will then drive the inner rod 27 to rise synchronously inside the second sliding groove 23. When the equipment rises to the designated position, the two threaded rings 26 can be rotated on the two screws 25. The rotation of the two threaded rings 26 will complete the limiting operation of the inner rod 27. Since the threaded rings 26 are threadedly connected to the screws 25, even if the equipment stops working suddenly, the two threaded rings 26 will still limit the equipment, effectively preventing it from falling suddenly, thus effectively ensuring the personal safety of the maintenance personnel. The upper end of the lifting platform 18 is provided with a placement groove 31, and a placement strip 32 is slidably installed inside the placement groove 31. Fixing blocks 33 are symmetrically fixedly installed on both side walls of the lifting platform 18, and fixing columns 34 are fixedly installed inside both sets of fixing blocks 33. When it is necessary to pick up an object during use, the placement strip 32 can be pulled out from the placement groove 31. At this time, the object can be lifted through the two placement grooves 31, which effectively avoids the need for maintenance personnel to stand on the edge of the platform and lean out to lift objects when using traditional equipment, and further ensures the safety of the equipment. Each of the two lifting platforms 18 has slots 35 on its side walls, and a connecting groove 36 is formed in the inner wall of each slot 35. Each of the two fixed posts 34 has a sleeve 41 fitted onto it, and each sleeve 41 has a symmetrically formed retaining groove 42 on its side wall. A first protective plate 43 is fixedly installed at the upper end of each sleeve 41, and a limit turntable 44 is symmetrically installed at the upper end of each first protective plate 43. Springs 45 are symmetrically fixedly installed in the inner wall of each of the two slots 35, and retaining strips 46 are fixedly installed on each of the two sets of springs 45. The locking strips 46 are slidably embedded in two slots 35. Connecting blocks 47 are fixedly installed at the upper ends of both locking strips 46. The two connecting blocks 47 are slidably embedded in two connecting grooves 36. Limiting grooves 48 are symmetrically formed on the opposite ends of the two first protective plates 43. Second protective plates 49 are inserted into each of the two sets of limiting grooves 48. Initially, the two first protective plates 43 can be kept vertical. Then, the two second protective plates 49 can be inserted into the two sets of limiting grooves 48 respectively. At this time, the two first protective plates 43 can be... Two limiting turntables 44 rotate on the protective plate 43, thereby limiting the two second protective plates 49, so that the equipment can effectively protect the maintenance personnel during use, enhancing the protective effect of the equipment on the maintenance personnel. After the equipment is used, the two connecting blocks 47 can be pulled relative to each other inside the two connecting slots 36. At this time, the two connecting blocks 47 will drive the two locking strips 46 to slide inside the two slots 35. At this time, the two locking strips 46 will drive the two sets of springs 45 to compress. At this time, the two locking strips 46 will slide out from the two locking slots 42. Then, the two sleeves 41 can be rotated on the two fixed columns 34. After the two sleeves 41 rotate the lifting platform 180°, the two connecting blocks 47 are released. At this time, the two sets of springs 45 will restore their elasticity and complete the locking of the sleeves 41 again. Then, step three can be repeated to complete the installation of the two second protective plates 49. At this time, the two sets of first protective plates 43 and second protective plates 49 will combine to complete the shielding of the equipment, thereby improving the protective effect of the equipment itself and extending the service life of the equipment.

[0021] To address the problems existing in the prior art, this invention provides a maintenance platform for inspecting high-altitude transformers. It comprises a screw, threaded rings, and an inner rod. The rotation of the two threaded rings causes the inner rod to be positioned. Since the threaded rings are threaded onto the screw, even if the equipment is interrupted due to an emergency, the two threaded rings will still limit the equipment, effectively preventing it from falling suddenly and thus ensuring the safety of the maintenance personnel. The platform also includes placement slots and placement bars. The placement bars can be pulled out of the placement slots, allowing objects to be lifted through the two slots. This effectively avoids the need for maintenance personnel to stand on the edge of the platform and lean out during lifting, as required by traditional equipment, further ensuring the safety of the equipment.

[0022] Working principle: First, the base 11 can be moved to the designated position, and the operator can then climb using the two ladders 14. At this point, the hydraulic cylinder 16 can be activated, causing the electric telescopic rod 17 to extend and retract. The electric telescopic rod 17 will then lift the lifting platform 18. The movement of the lifting platform 18 will cause the two sliding columns 28 to slide upwards within the two fixed cylinders 22. The two sliding columns 28 will then cause the two sets of sliders 29 to slide within the two sets of third sliding grooves 24, thus effectively ensuring... To ensure the stability of the equipment during lifting, the two sliding columns 28 will drive the inner rod 27 to rise synchronously inside the second sliding groove 23. When the equipment rises to the designated position, the two threaded rings 26 can be rotated on the two screws 25. The rotation of the two threaded rings 26 will complete the limiting operation of the inner rod 27. Since the threaded rings 26 are threadedly connected to the screws 25, even if the equipment stops working suddenly, the two threaded rings 26 will limit the equipment, effectively preventing it from falling suddenly, and thus effectively protecting the personal safety of the maintenance personnel. The second step is that when it is necessary to pick up an object during use, the placement bar 32 can be pulled out from the placement slot 31. At this time, the object can be lifted through the two placement slots 31, which effectively avoids the need for the maintenance personnel to stand on the edge of the platform and lean out to lift the object when using traditional equipment, and further ensures the safety of the equipment. Third, in the initial state, the two first protective plates 43 can be kept in a vertical position. Then, the two second protective plates 49 can be inserted into the two sets of limiting slots 48 respectively. At this time, the two limiting turntables 44 can be rotated on the two first protective plates 43 to limit the two second protective plates 49. This allows the equipment to form effective protection for the maintenance personnel during use, enhancing the equipment's protection effect on the maintenance personnel. Fourth, after the equipment is used, the two connecting blocks 47 can be pulled relative to each other inside the two connecting slots 36. The two connecting blocks 47 will then drive the two locking strips 46 to slide inside the two slots 35. The two locking strips 46 will then drive the two sets of springs 45 to compress. The two locking strips 46 will then slide out of the two slots 42. Then, the two sleeves 41 can be rotated on the two fixed columns 34. After the two sleeves 41 are rotated 180° on the lifting platform, the two connecting blocks 47 are released. The two sets of springs 45 will then regain their elasticity and re-engage the sleeves 41. Step three can then be repeated to complete the installation of the two second protective plates 49. At this point, the two sets of first protective plates 43 and second protective plates 49 will combine to shield the equipment, thereby improving the equipment's protective effect and extending its service life.

Many modifications and variations will be apparent to those skilled in the art.
