Description

Technical Field

[0001] This invention relates to the field of transformer support technology, and in particular to a voltage transformer support device. Background Technology

[0002] Voltage transformers, as key metering and protection devices in power systems, are widely used in transmission lines, substations, and other scenarios. Their installation stability and operational safety directly affect the reliable operation of the power system. Voltage transformer support devices are mechanical structural components used to support and fix the voltage transformer body and related components, ensuring its positional stability in installation, operation, display, or assembly scenarios. They are indispensable auxiliary devices in voltage transformer systems. They must not only bear the weight of the voltage transformer itself, but also adapt to the installation, display, or assembly requirements of different usage scenarios, while meeting the stability and safety requirements of power equipment operation.

[0003] Existing voltage transformer support devices lack effective anti-fall and buffer protection mechanisms in actual use. They often fix the transformer body by single-sided clamping or bolt fastening, which is difficult to adapt to the installation requirements of transformers of different specifications. Moreover, the clamping force is uneven, and under the action of external forces such as outdoor wind and line vibration, the transformer is prone to loosening, displacement, or even falling off, which seriously threatens the safety of power transmission. Furthermore, when the support components break or fail, the transformer is prone to fall directly, causing equipment damage and even secondary accidents such as line short circuits. The device itself is also prone to fatigue damage of device components due to instantaneous impact force, shortening its service life.

[0004] Therefore, a voltage transformer support device is proposed to address the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, such as the lack of effective fall protection and buffering mechanisms, a voltage transformer support device is proposed.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a voltage transformer support device, including a transformer body, a fixing mechanism for fixing the transformer body is provided below the transformer body, and a driving mechanism for moving the transformer body is provided on one side of the fixing mechanism. The drive mechanism includes a support frame, a limiting plate is fixedly connected inside the support frame, and symmetrical grooves are formed on the outer surface of the limiting plate. Multiple limiting grooves are arrayed at one end of the support frame near the transformer body. Transport components are symmetrically arranged inside the support frame, and a hydraulic oil transport device is provided between two transport components. A buffer component is provided on the side of the hydraulic oil transport device near the transformer body. A fixing plate is provided on the side of each transport component near the transformer body, and a hydraulic telescopic rod is symmetrically arranged between the two fixing plates.

[0007] Preferably, the support frame is fixed to the utility pole with bolts and fasteners, and the hydraulic oil transport device consists of a hydraulic oil storage tank and a hydraulic oil pumping device.

[0008] Preferably, the hydraulic telescopic rod is embedded in the surface of the lower fixed plate, and the telescopic end of the hydraulic telescopic rod is fixedly connected to the upper fixed plate.

[0009] Preferably, the fixing mechanism includes a support plate fixed to the outer surface of the upper fixing plate. The support plate has multiple arc-shaped grooves arranged in an array at one end near the transformer body. A rectangular groove is formed in the middle of the top of the support plate. A lower pressure plate is elastically connected in the rectangular groove. A drive rod is fixedly connected to the middle of the lower pressure plate away from the transformer body. A movable frame is fixedly connected to the end of the drive rod away from the transformer body. Multiple connecting rods are rotatably connected in an array on the outer surface of the movable frame. Movable blocks are slidably connected in each of the multiple arc-shaped grooves. The multiple movable blocks are rotatably connected to the multiple connecting rods respectively. A clamping column is fixedly connected to the end of the multiple movable blocks near the transformer body.

[0010] Preferably, in the initial state, the lower pressure plate is located above the clamping column, and in the working state, multiple clamping columns simultaneously adhere to the outer surface of the transformer body.

[0011] Preferably, the transport assembly includes a transport housing located within a support frame. Electric telescopic rods are symmetrically fixedly connected to the outer surface of the transport housing. T-shaped frames are fixedly connected to the telescopic ends of both electric telescopic rods. Two rollers are rotatably connected to the adjacent ends of the two T-shaped frames. A support housing is fixedly connected inside the transport housing. A limiting plate is rotatably connected inside the support housing. Multiple elastic elements are fixedly connected in an array between the limiting plate and the inner wall of the support housing. A five-star wheel is rotatably connected inside the transport housing.

[0012] Preferably, the rollers are located inside the limiting plate on the same side, and the outer surface of the five-star wheel is always in contact with the limiting plate.

[0013] Preferably, the buffer assembly includes a sealed housing, one end of which is fixedly connected to the output end of the hydraulic oil pumping device via a rubber tube. A fixed tube is fixedly connected inside the sealed housing. Multiple arc-shaped holes are arrayed on the outer surface of the fixed tube. A movable sleeve is fitted onto the outer surface of the fixed tube. Elastic elements are symmetrically fixedly connected between the inner wall of the movable sleeve and the outer surface of the fixed tube. A permanent magnet ring is fixedly connected to the inner wall of the movable sleeve. An electromagnetic ring is fixedly connected to the outer surface of the fixed tube. The permanent magnet ring and the electromagnetic ring repel each other magnetically.

[0014] Preferably, the connection between the movable sleeve and the fixed tube is a sliding connection, and the other end of the sealed housing is connected to multiple hydraulic telescopic rods by a hose.

[0015] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows: 1. This invention provides a voltage transformer support device. Through a combination of magnetic repulsion and elastic elements, combined with the flow damping characteristics of hydraulic oil, in the event of device component breakage or transformer accidental drop, the hydraulic oil flow rate can be controlled by adjusting the communication area of ​​the arc-shaped hole to buffer the impact force of the drop and prevent damage to the transformer and device components due to instantaneous impact. At the same time, the magnetic repulsion between the permanent magnet ring and the electromagnetic ring, together with the elastic elements, can balance the pressure fluctuations of the hydraulic system, reduce component fatigue wear, and extend the overall service life of the device.

[0016] 2. This invention provides a voltage transformer support device. By cooperating with the rollers and slides of the transport component, the transformer can be moved smoothly. With the extension and retraction adjustment of the hydraulic telescopic rod, the installation height of the transformer can be precisely controlled. There is no need for manual handling and positioning, which greatly reduces the intensity and safety risks of high-altitude operations. Moreover, the meshing structure between the five-star wheel and the limiting plate can correct the deviation of the movement trajectory in real time, ensuring a smooth transportation process. At the same time, it realizes a one-way anti-fall function to prevent the transport component from accidentally sliding down.

[0017] 3. This invention provides a voltage transformer support device. Through a multi-directional synchronous clamping structure of the fixing mechanism, the lower pressure plate is driven by the self-weight of the transformer body to move multiple clamping columns toward the center, tightly fitting the outer surface of the transformer from multiple angles to achieve balanced clamping. This effectively prevents the transformer from shaking or shifting during use. At the same time, rubber sleeves are fitted on the surface of the clamping columns, which not only enhances the friction but also prevents excessive clamping force from damaging the surface of the transformer. It can be adapted to voltage transformers of different specifications, significantly improving its versatility. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Specific implementation examples are given below.

[0022] Please see Figure 1 - Figure 8 The present invention provides a technical solution: a voltage transformer support device, including a transformer body 1, a fixing mechanism 2 for fixing the transformer body 1 is provided below the transformer body 1, and a driving mechanism 3 for moving the transformer body 1 is provided on one side of the fixing mechanism 2.

[0023] like Figure 5As shown, the fixing mechanism 2 includes a support plate 21 fixed to the outer surface of the upper fixing plate 38. The support plate 21 has multiple arc-shaped grooves 22 arrayed at one end near the transformer body 1. A rectangular groove is opened at the middle of the top of the support plate 21. A lower pressure plate 23 is elastically connected in the rectangular groove. A drive rod is fixedly connected at the middle of the lower pressure plate 23 away from the transformer body 1. A movable frame 24 is fixedly connected at the end of the drive rod away from the transformer body 1. Multiple connecting rods 25 are rotatably connected to the outer surface of the movable frame 24. Movable blocks 26 are slidably connected in the multiple arc-shaped grooves 22. The multiple movable blocks 26 are rotatably connected to the multiple connecting rods 25 respectively. Clamping columns 27 are fixedly connected to the end of the multiple movable blocks 26 near the transformer body 1. In the initial state, the lower pressure plate 23 is located above the clamping columns 27. In the working state, the multiple clamping columns 27 simultaneously adhere to the outer surface of the transformer body 1. Specifically, the lower pressure plate 23 first contacts and is squeezed against the upper surface of the transformer body 1. The drive rod drives the movable frame 24 to move away from the transformer body 1. The multiple connecting rods 25 rotatably connected to the surface of the movable frame 24 rotate synchronously, pushing the movable block 26 in the arc groove 22 to slide along the arc groove 22. Finally, the multiple clamping columns 27 are driven to converge towards the center and tightly fit against the outer surface of the transformer body 1. This multi-directional synchronous clamping structure can fix the transformer body 1 from different angles, greatly improving the clamping stability and effectively preventing the transformer body 1 from shaking or shifting during subsequent use, thus ensuring the safe operation of the power system. It should be noted that the weight of the transformer body 1 drives the multiple clamping columns 27 to clamp it, which can ensure the overall clamping force of the device. The surface of the clamping columns 27 is covered with a rubber sleeve, which can further enhance the friction between the column and the surface of the transformer body 1, thereby ensuring the stability of the transformer body 1 and preventing scratches on the surface of the transformer body 1 due to large clamping force.

[0024] like Figure 6 As shown, the drive mechanism 3 includes a support frame 31, with a limiting plate 32 fixedly connected inside the support frame 31. The outer surface of the limiting plate 32 is symmetrically provided with sliding grooves 33. Multiple limiting slots 34 are arrayed at one end of the support frame 31 near the transformer body 1. Transport components 35 are symmetrically provided inside the support frame 31. A hydraulic oil transport device 36 is provided between two transport components 35. A buffer component 37 is provided on the side of the hydraulic oil transport device 36 near the transformer body 1. Fixed plates 38 are provided on the side of each of the two transport components 35 near the transformer body 1. A hydraulic telescopic rod 39 is symmetrically provided between the two fixed plates 38. The support frame 31 is fixed to the utility pole with bolts and fixing buckles. The hydraulic oil transport device 36 consists of a hydraulic oil storage tank and a hydraulic oil pumping device. The hydraulic telescopic rod 39 is embedded in the surface of the lower fixed plate 38, and the telescopic end of the hydraulic telescopic rod 39 is fixedly connected to the upper fixed plate 38.

[0025] like Figure 7 As shown, the transport assembly 35 includes a transport housing 351 located within a support frame 31. Electric telescopic rods 352 are symmetrically fixedly connected to the outer surface of the transport housing 351. T-shaped frames 353 are fixedly connected to the telescopic ends of both electric telescopic rods 352. Two rollers 358 are rotatably connected to the ends of the two T-shaped frames 353 that are close to each other. A support housing 354 is fixedly connected inside the transport housing 351. A limiting plate 355 is rotatably connected inside the support housing 354. Multiple elastic elements 356 are fixedly connected in an array between the limiting plate 355 and the inner wall of the support housing 354. A five-star wheel 357 is rotatably connected inside the transport housing 351. The rollers 358 are located within a limiting plate 32 on the same side. The outer surface of the five-star wheel 357 is always in contact with the limiting plate 355. Specifically, the electric telescopic rod 352 of the transport component 35 is synchronously energized and activated, and its telescopic end pushes the T-shaped frame 353 to move axially. The two ends of the T-shaped frame 353 are rotatably connected to the rollers 358 through the rotating shaft. The outer surface of the rollers 358 is in close contact with the inner wall of the slide groove 33. When moving, the rollers 358 roll along the slide groove 33 to reduce frictional resistance. At the same time, the support shell 354 inside the transport housing 351 is welded and fixed to the inner wall of the transport housing 351. The limiting plate 355 inside the support shell 354 is rotatably connected through the rotating shaft. The elastic elements 356 fixed in an array between the limiting plate 355 and the inner wall of the support shell 354 always apply elastic pressure to the limiting plate 355. This structure ensures that the limiting plate 355 and the outer tooth surface of the five-star wheel 357 are tightly engaged. The five-star wheel 357 is rotatably connected to the inner wall of the transport housing 351 via a rotating shaft, and its outer tooth surface is always in contact with the limiting plate 355. This structure can correct the deviation of the movement trajectory of the transport housing 351 in real time, ensuring that the transport housing 351 moves smoothly along the length direction of the support frame 31. When the five-star wheel 357 is in the limiting groove 34, the transport housing 351 can only move upward. When it falls downward, the five-star wheel 357 will reverse, and the limiting plate 355 will be supported by the inner wall of the support housing 354. Thus, when the five-star wheel 357 cannot rotate, the transport housing 351 cannot fall downward.

[0026] like Figure 8As shown, the buffer assembly 37 includes a sealed housing 371. One end of the sealed housing 371 is fixedly connected to the output end of the hydraulic oil pumping device via a rubber tube. A fixed tube 372 is fixedly connected inside the sealed housing 371. Multiple arc-shaped holes 373 are arrayed on the outer surface of the fixed tube 372. A movable sleeve 374 is fitted onto the outer surface of the fixed tube 372. Elastic elements 375 are symmetrically fixedly connected between the inner wall of the movable sleeve 374 and the outer surface of the fixed tube 372. A permanent magnet ring 376 is fixedly connected to the inner wall of the movable sleeve 374. An electromagnetic ring 377 is fixedly connected to the outer surface of the fixed tube 372. The permanent magnet ring 376 and the electromagnetic ring 377 are magnetically repelled. The connection between the movable sleeve 374 and the fixed tube 372 is a sliding connection. The other end of the sealed housing 371 is connected to multiple hydraulic telescopic rods 39 via a flexible hose. When the rigidity of the... When a component breaks, the transformer body 1 will cause the transport housing 351 located above to move downwards. At this time, the current flowing into the electromagnetic ring 377 will be reduced. The two elastic elements 375 will cause the movable sleeve 374 to move towards the side closer to the fixed tube 372, thereby reducing the communication area between the arc-shaped hole 373 and the sealing housing 371. During the downward movement of the transport housing 351 located above, the hydraulic telescopic rod 39 will be squeezed and contracted. The hydraulic oil in the hydraulic telescopic rod 39 will flow through the crowded arc-shaped hole 373 into the sealing housing 371, and then into the rubber tube. The fluidity of the hydraulic oil can buffer the huge force generated when the transformer body 1 falls, ensuring that the transformer body 1 will not be damaged, improving the safety of the device during use, and the hydraulic oil pumping device will not be damaged due to the backflow of hydraulic oil. It should be noted that the permanent magnet ring 376 and the electromagnetic ring 377 are existing devices or combinations of existing devices. Those skilled in the art can implement the above solution without creative modifications based on the above description.

[0027] The working principle of this invention is as follows: In use, the support frame 31 of the drive mechanism 3 is first fixed to the utility pole using bolts and fasteners. This double-fixing structure ensures the overall stability of the device, eliminating safety hazards caused by loose installation. Then, the transformer body 1 is placed on the lower pressure plate 23. The lower pressure plate 23 first contacts and is compressed against the upper surface of the transformer body 1. The drive rod drives the movable frame 24 to move away from the transformer body 1. Multiple connecting rods 25 rotatably connected to the surface of the movable frame 24 rotate synchronously, pushing the movable block 26 within the arc-shaped groove 22 to slide along the arc-shaped groove 22. Finally, this causes multiple clamping columns 27 to converge towards the center. This multi-directional synchronous clamping structure, which closely fits the outer surface of the transformer body 1, can fix the transformer body 1 from different angles, greatly improving clamping stability and effectively preventing the transformer body 1 from shaking or shifting during subsequent use, thus ensuring the safe operation of the power system. It should be noted that the weight of the transformer body 1 drives multiple clamping columns 27 to clamp it, which can ensure the overall clamping force of the device. Furthermore, the surface of the clamping columns 27 is covered with a rubber sleeve, which can further enhance the friction between the column and the surface of the transformer body 1, thereby ensuring the stability of the transformer body 1 and preventing scratches on the surface of the transformer body 1 due to large clamping force. It should be noted that before clamping and fixing the transformer body 1 by the fixing mechanism 2, the two transport housings 351 need to be installed into the support frame 31. The hydraulic telescopic rod 39 of the drive mechanism 3 is embedded and fixed to the surface of the lower fixing plate 38, and the telescopic end is welded and fixed to the upper fixing plate 38 and is in a fully retracted state to minimize the distance between the upper and lower fixing plates 38. The electric telescopic rod 352 of the transport component 35 is fixed to the inner wall of the transport housing 351, and its telescopic end is vertically connected to the middle of the T-shaped frame 353. The rollers 358 at both ends of the T-shaped frame 353 are engaged with the sliding of the limiting plate 32. Inside the groove 33, each component is precisely positioned to its initial working position, laying a stable foundation for subsequent operations and effectively avoiding subsequent clamping misalignment caused by initial position deviation. During this process, one end of the elastic element 375, which is symmetrically fixed to the inner wall of the movable sleeve 374, is welded to the outer wall of the fixed tube 372, and the other end is in contact with the inner wall of the movable sleeve 374. At the same time, the permanent magnet ring 376 on the inner wall of the movable sleeve 374 and the electromagnetic ring 377 on the outer surface of the fixed tube 372 are opposite to each other, forming a magnetic repulsion force, which connects the arc-shaped hole 373 with the sealing shell 371, allowing the hydraulic oil to flow smoothly in the pipeline. The electric telescopic rod 352 of the transport assembly 35 is synchronously energized and activated. Its telescopic end pushes the T-shaped frame 353 axially. The two ends of the T-shaped frame 353 are rotatably connected to the rollers 358 via rotating shafts. The outer surface of the rollers 358 is in close contact with the inner wall of the slide groove 33. During movement, the rollers 358 roll along the slide groove 33, reducing frictional resistance. At the same time, the support shell 354 inside the transport housing 351 is welded and fixed to the inner wall of the transport housing 351. The limiting plate 355 inside the support shell 354 is rotatably connected via a rotating shaft. The elastic elements 356 fixed in an array between the limiting plate 355 and the inner wall of the support shell 354 always apply elastic pressure to the limiting plate 355, so that... The limiting plate 355 is tightly engaged with the outer tooth surface of the five-star wheel 357. The five-star wheel 357 is rotatably connected to the inner wall of the transport housing 351 through a rotating shaft, and its outer tooth surface is always in contact with the limiting plate 355. This structure can correct the deviation of the movement trajectory of the transport housing 351 in real time, ensuring that the transport housing 351 moves smoothly along the length direction of the support frame 31. When the five-star wheel 357 is in the limiting groove 34, the transport housing 351 can only move upward. When it falls downward, the five-star wheel 357 will reverse, and the limiting plate 355 will be supported by the inner wall of the support housing 354. Thus, when the five-star wheel 357 cannot rotate, the transport housing 351 cannot fall downward. Subsequently, the hydraulic oil pumping device of the hydraulic oil transport device 36 is activated. The motor in this device drives the oil pump to operate, pressurizing the hydraulic oil in the hydraulic oil storage tank and then transporting it through a high-pressure resistant rubber hose to the inlet end of the sealing housing 371 of the buffer assembly 37. The sealing housing 371 is welded and sealed to one end of the fixed pipe 372. After the hydraulic oil enters the fixed pipe 372, it flows into the gap between the movable sleeve 374 and the fixed pipe 372 through the arc-shaped holes 373 arrayed on its outer surface, and then through multiple pipes connected to the end of the movable sleeve 374. Branch hoses are distributed to the oil inlets of the corresponding hydraulic telescopic rods 39, causing the hydraulic telescopic rods 39 to extend and drive the fixed plate 38 located above to move upward. When the hydraulic telescopic rods 39 can no longer extend, the electric telescopic rod 352 located above is activated, causing the five-star wheel 357 located above to contact the limiting groove 34, and causing the five-star wheel 357 located below to disengage from the limiting groove 34. Then, the hydraulic telescopic rods 39 retract, driving the transport housing 351 located below to move upward. By repeating this process, the transformer body 1 can be continuously moved upward. During use, the upper transport housing 351 bears the weight of the transformer body 1. When a rigid component breaks, the transformer body 1 causes the upper transport housing 351 to move downwards. This reduces the current supplied to the electromagnetic ring 377. The two elastic elements 375 move the movable sleeve 374 closer to the fixed tube 372, thereby reducing the communication area between the arc-shaped hole 373 and the sealing housing 371. As the upper transport housing 351 moves downwards, it compresses the hydraulic telescopic rod 39, causing it to contract. The hydraulic oil in the hydraulic telescopic rod 39 flows through the congested arc-shaped hole 373 into the sealing housing 371, and then into the rubber tube. The fluidity of the hydraulic oil buffers the huge force generated when the transformer body 1 falls, ensuring that the transformer body 1 is not damaged, improving the safety of the device during use, and preventing damage to the hydraulic oil pumping device due to backflow of hydraulic oil.
