Description

Technical Field

[0001] This invention relates to the field of electrical equipment installation technology, specifically to a precision installation device for high-voltage electrical equipment. Background Technology

[0002] The high-voltage electrical equipment precision installation device is an auxiliary device used in the construction phase of substations. It is adapted to the installation requirements of high-voltage core equipment such as main transformers. As a key equipment for energy conversion in substations, main transformers generally have the characteristics of tens of tons in weight and ultra-large volume. Their installation accuracy is directly related to the operational stability of the equipment.

[0003] During the main transformer installation, a crane is typically used for equipment hoisting. When the main transformer approaches the installation point (which consists of two bases corresponding to two pre-installed plates at the bottom of the transformer casing), several workers are needed to adjust the casing to ensure the transformer's alignment with the installation point. This is done to guarantee the accuracy of the installation. (During the installation process, the dimensions of the bases must match the dimensions of the pre-installed plates at the bottom of the transformer casing to ensure stability and facilitate alignment observation.) Even a slight deviation requires re-installation. The repeated adjustments to the newly hoisting equipment, relying on manual experience, are inefficient and can take several hours or even longer. Because manual adjustments make it difficult to precisely control the force and angle, they can easily lead to an imbalance in the main transformer body, causing it to sway during hoisting. This can cause high-precision internal parts to shift. Furthermore, the risk of collisions between the equipment and the foundation increases during repeated hoisting and adjustments, which may cause deformation of the sealing surfaces of accessories, resulting in excessive gaps in subsequent connections. This can lead to problems such as leakage of insulating oil and gas, ultimately causing a decline in the insulation performance of the equipment, abnormal operating noises, and in severe cases, even major failures such as short circuits and equipment burnout.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing precision installation devices for high-voltage electrical equipment. Summary of the Invention

[0005] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide a precise installation device for high-voltage electrical equipment, thereby solving the problem mentioned in the background art where manual correction of the large size of the main transformer is time-consuming and labor-intensive.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-voltage electrical equipment precision installation device, comprising a transformer body, a transformer base body disposed at the bottom of the outer wall of the transformer body, a base body disposed on both sides of the bottom of the transformer base body, and further comprising: A correction mechanism is installed at the bottom of the transformer base body; Control mechanisms connected to the interior of the correctional facility; The correction mechanism includes a chassis disposed at the bottom of the transformer base body, a movable rod movably disposed on the outer wall of the chassis, a correction plate connected to one end of the movable rod, and a top plate movably disposed on the inner wall of the correction plate; The control mechanism includes an outer compartment movably disposed at the front of the chassis, and a connecting rod movably disposed on the inner wall of the outer compartment, with a rack connected to one end of the connecting rod.

[0007] Preferably, the inner wall of the chassis is movably provided with a linkage gear, both ends of the straightening plate are movably provided with positioning plates, and the bottom of the top plate and the positioning plates are connected with telescopic rods; The outer wall of the telescopic rod is surrounded by a spring.

[0008] Preferably, the outer wall of the outer compartment is connected to a flexible hose, and one end of the flexible hose is connected to a foot pedal; The inner wall of the outer compartment is hollow.

[0009] Preferably, the chassis has a cavity, and the rack is movably disposed within the cavity of the chassis; One side of the outer wall of the rack is in contact with the outer wall of the linkage gear.

[0010] Preferably, the outer wall of the chassis is symmetrically provided with sliding grooves, and the movable rod is movably connected to the sliding grooves of the chassis.

[0011] Preferably, the positioning plate has a cuboid shape in three-dimensional view, and one side of the outer wall of the positioning plate is inclined.

[0012] Preferably, a toothed groove is provided on one side of the outer wall of the movable rod, and the toothed groove of the movable rod meshes with the linkage gear; The movable rod and the linkage gear form a meshing transmission connection.

[0013] Preferably, one end of the connecting rod is rectangular, and the diameter of one end of the connecting rod is adapted to the diameter of the inner wall of the outer compartment; One end of the connecting rod is movably connected to the inner wall of the outer compartment.

[0014] Preferably, one end of the hose is connected to and communicates with the outer compartment, and the other end of the hose is connected to and communicates with the inner wall of the foot pedal.

[0015] Preferably, the inner walls of the outer compartment, the hose, and the foot pedal are all provided with liquid; The outer compartment, hose, and foot pedal are all interconnected.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. By incorporating a correction mechanism and a control mechanism, the transformer body can be aligned and adjusted between the transformer base and the pedestal body without complex operations during installation. In traditional equipment installation processes, multiple people are often required to adjust the positions of the transformer base and the pedestal body, resulting in complex division of labor and the need for re-lifting after each adjustment deviation, often taking several hours. This invention, through the correction and control mechanisms, enables automatic centering adjustment of the transformer body. Users only need to complete three core steps: pre-placing the equipment, operating the equipment, and removing the equipment. The operation process involves only the worker stepping on a pedal, and the entire debugging process can be completed by a single person, thereby reducing the reliance on multiple people and significantly shortening the time spent on the alignment stage. This improves the installation accuracy of the transformer body and greatly enhances work efficiency.

[0017] 2. Traditional manual adjustment relies on experience and judgment, which can easily lead to imbalance of force on the transformer body due to inaccurate force control, causing internal winding misalignment and displacement of high-precision parts. Moreover, the risk of collision between the equipment and the foundation during repeated lifting is extremely high, which can easily cause problems such as deformation of accessory sealing surfaces and excessive docking gaps, creating hidden dangers for faults such as insulating oil leakage and gas leakage. This invention achieves single-person correction through the setting of correction and control mechanisms. Because the adjustment is carried out when the transformer body is in a suspended state, the bidirectional correction of the correction plate, top plate and positioning plate ensures that the transformer base body and the base body move downwards in a vertical alignment, avoiding uneven force on the transformer body. At the same time, it eliminates the need for repeated lifting, fundamentally reducing the risk of equipment collision and part displacement, ensuring the horizontality and alignment accuracy of the main transformer installation, and effectively reducing the probability of faults such as insulation performance degradation, abnormal operating noise, and short circuits.

[0024] 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.

[0025] Please see Figures 1 to 11 The present invention provides a technical solution: a high-voltage electrical equipment precision installation device, including a transformer body 1, a transformer base body 4 disposed at the bottom of the outer wall of the transformer body 1, and base bodies 5 disposed on both sides of the bottom of the transformer base body 4, and further comprising: The correction mechanism 2 is located at the bottom of the transformer base body 4; Control mechanism 3 is connected to the inside of the correction mechanism 2; The correction mechanism 2 includes a chassis 201 disposed at the bottom of the transformer base body 4. A movable rod 203 is movably disposed on the outer wall of the chassis 201. One end of the movable rod 203 is connected to a correction plate 204. A top plate 207 is movably disposed on the inner wall of the correction plate 204. The control mechanism 3 includes an outer compartment 301 movably disposed at the front of the chassis 201. A connecting rod 304 is movably disposed on the inner wall of the outer compartment 301, and a rack 305 is connected to one end of the connecting rod 304.

[0026] In this embodiment, the alignment mechanism 2 and the control mechanism 3 enable the transformer body 1 to be aligned with the transformer base body 4 and the base body 5 without complex operations during installation. In traditional equipment installation processes, multiple people are often required to adjust the positions of the transformer base body 4 and the base body 5. This not only involves complex division of labor but also requires re-lifting after each adjustment deviation, often resulting in a work cycle of several hours. This invention, through the alignment mechanism 2 and the control mechanism 3, enables the automatic centering adjustment of the transformer body 1. Users only need to complete three core steps: pre-placing the equipment, operating the equipment, and removing the equipment. The operation process only requires the worker to step on the foot pedal 303. The entire debugging process can be completed by a single person, thereby reducing the reliance on multiple people and significantly shortening the time spent on the alignment process. This improves the installation accuracy of the transformer body 1 and greatly enhances work efficiency.

[0027] The inner wall of the chassis 201 is movably provided with a linkage gear 202, and both ends of the straightening plate 204 are movably provided with positioning plates 208. The bottom of the top plate 207 and the positioning plates 208 are both connected with telescopic rods 205. A spring 206 is arranged around the outer wall of the telescopic rod 205.

[0028] In this embodiment, traditional manual adjustment relies on experience and judgment, which can easily lead to imbalance of force on the transformer body 1 due to inaccurate force control, causing internal winding misalignment and displacement of high-precision parts. Moreover, the risk of collision between the equipment and the foundation during repeated lifting is extremely high, which can easily cause problems such as deformation of accessory sealing surfaces and excessive docking gaps, creating hidden dangers for faults such as insulating oil leakage and gas leakage. This invention achieves single-person correction through the setting of the correction mechanism 2 and the control mechanism 3. Since the adjustment is carried out when the transformer body 1 is in a suspended state, the bidirectional correction of the correction plate 204, the top plate 207 and the positioning plate 208 ensures that the transformer base body 4 and the base body 5 move downwards in a vertical alignment, avoiding uneven force on the transformer body 1. At the same time, it eliminates the need for repeated lifting, reducing the risk of equipment collision and part displacement from the root, ensuring the horizontality and alignment accuracy of the main transformer installation, and effectively reducing the probability of faults such as insulation performance degradation, abnormal operating noise and short circuit.

[0029] A flexible hose 302 is connected to the outer wall of the outer compartment 301, and a foot pedal 303 is connected to one end of the flexible hose 302. The inner wall of outer compartment 301 is hollow.

[0030] In this embodiment, as the equipment is pressed down, the bottom of the transformer base body 4 presses against the top plate 207 and moves downward until the bottom of the transformer base body 4 is in contact with the base body 5, thus completing the installation. After installation, the worker releases their foot, and the foot pedal 303 resets (it has its own elastic reset component). After resetting, the foot pedal 303 will drive a certain amount of air through the hose 302 to create a negative pressure on the inner wall of the outer chamber 301. At this time, the negative pressure will drive the connecting rod 304 on the inner wall of the outer chamber 301 to reset. After the connecting rod 304 resets, it will... The rack 305 drives the linkage gear 202 to reverse, at which time the movable rod 203 and the straightening plate 204 will be reset, so that the overall diameter is smaller than the diameter between the base bodies 5. Then the staff can remove the straightening mechanism 2 and the control mechanism 3 from the bottom of the transformer base body 4. (When adjusting the position of the transformer body 1, since the transformer body 1 is in a suspended state, the staff does not need to use much force when stepping on the foot pedal 303 to straighten the position of the transformer base body 4 through the straightening plate 204, the top plate 207 and the positioning plate 208.)

[0031] The chassis 201 has a cavity, and the rack 305 is movably disposed within the cavity of the chassis 201; One side of the outer wall of the rack 305 is in contact with the outer wall of the linkage gear 202.

[0032] In this embodiment, the worker places the chassis 201 approximately at the center of the base body 5, and then steps on the foot pedal 303. When the foot pedal 303 is stepped on, the liquid inside the foot pedal 303 flows towards the inner wall of the outer chamber 301. At this time, the liquid flows into the inner wall of the outer chamber 301 through the hose 302. When the liquid enters the inner wall of the outer chamber 301, it squeezes one end of the connecting rod 304. Because one end of the connecting rod 304 has the same diameter as the inner wall of the outer chamber 301, the connecting rod 304 is pushed and moved. When the connecting rod 304 is pushed and moved, it drives the rack 305 to move in the same direction. As the rack 305 moves, it drives the linkage gear 202 to rotate. When the linkage gear 202 rotates, its tooth groove meshes with the tooth groove of the movable rod 203, so the movable rod 203 will be driven to move. At this time, the movable rod 203 will exhibit relative motion and form a motion trajectory similar to expansion. (When the straightening plate 204, the top plate 207, and the positioning plate 208 are straightening the bottom of the transformer base body 4, if there is a deviation at the bottom of the transformer base body 4, the straightening plate 204 and the top plate 207 will push the transformer base body 4 so that the transformer base body 4 is flush with the base body 5.)

[0033] The outer wall of the chassis 201 is symmetrically provided with sliding grooves, and the movable rod 203 is movably connected to the sliding grooves of the chassis 201.

[0034] In this embodiment, when the liquid enters the inner wall of the outer chamber 301, it will squeeze one end of the connecting rod 304. Since one end of the connecting rod 304 has the same diameter as the inner wall of the outer chamber 301, the connecting rod 304 will be pushed to move. When the connecting rod 304 is pushed to move, it will drive the rack 305 to move synchronously. When the rack 305 moves, it will drive the linkage gear 202 to rotate. When the linkage gear 202 rotates, its tooth groove meshes with the tooth groove of the movable rod 203, so the movable rod 203 will be driven to move. At this time, the movable rod 203 will exhibit relative motion and form a motion trajectory similar to expansion. When the movable rod 203 moves, it will drive the straightening plate 204 to move. When the straightening plate 204 moves, it will gradually fit against one side of the outer wall of the base body 5. When the straightening plate 204 moves to a certain position, the inclined surface of one side of the outer wall of the positioning plate 208 will touch the outer wall of the base body 5. Since one side of the outer wall of the positioning plate 208 is inclined, the positioning plate 208 will be driven to move.

[0035] The three-dimensional view of the positioning plate 208 is a cuboid, and one side of the outer wall of the positioning plate 208 is inclined.

[0036] In this embodiment, because one side of the outer wall of the positioning plate 208 is inclined, the positioning plate 208 will be moved. Since the outer wall of the positioning plate 208 is connected to the telescopic rod 205 and the spring 206, the positioning plate 208 will move against the front and back of the outer wall of the base body 5, causing the chassis 201 to move to a certain extent. After the chassis 201 moves, the correction is completed. At this time, the worker can release his foot. Then, the worker operates the crane to transport the transformer body 1 to the base body 5 and gradually lowers the transformer body 1. When the transformer base body 4 at the bottom of the transformer body 1 is close to the top of the outer wall of the base body 5 (the transformer body 1 is still in a suspended state), the worker steps on the foot pedal 303 again, and the above operation will be repeated. At this time, one side of the outer wall of the correction plate 204 will contact the bottom of the outer wall of the transformer base body 4 where it needs to be aligned with the base body 5. With the symmetrical push of the correction plate 204, the correction plate 204 will gradually calibrate the transformer base body 4.

[0037] A toothed groove is provided on one side of the outer wall of the movable rod 203, and the toothed groove of the movable rod 203 meshes with the linkage gear 202; The movable rod 203 and the linkage gear 202 form a meshing transmission connection.

[0038] In this embodiment, when the foot pedal 303 receives a stepping force, the liquid inside the foot pedal 303 will flow into the inner wall of the outer chamber 301. At this time, the liquid will flow into the inner wall of the outer chamber 301 through the hose 302. When the liquid enters the inner wall of the outer chamber 301, it will squeeze one end of the connecting rod 304. Since one end of the connecting rod 304 has the same diameter as the inner wall of the outer chamber 301, the connecting rod 304 will be pushed to move. When the connecting rod 304 is pushed to move, it will drive the rack 305 to move synchronously. When the rack 305 moves, it will drive the linkage gear 202 to rotate. When the linkage gear 202 rotates, its tooth groove meshes with the tooth groove of the movable rod 203, so the movable rod 203 will be driven to move. At this time, the movable rod 203 will exhibit relative motion and form a motion trajectory similar to expansion.

[0039] One end of the connecting rod 304 is rectangular, and the diameter of one end of the connecting rod 304 is adapted to the diameter of the inner wall of the outer compartment 301. One end of the connecting rod 304 is movably connected to the inner wall of the outer compartment 301.

[0040] In this embodiment, because one end of the connecting rod 304 has the same diameter as the inner wall of the outer chamber 301, the connecting rod 304 is pushed to move. When the connecting rod 304 is pushed to move, it drives the rack 305 to move synchronously. When the rack 305 moves, it drives the linkage gear 202 to rotate. When the linkage gear 202 rotates, its tooth groove meshes with the tooth groove of the movable rod 203, so the movable rod 203 is driven to move. At this time, the movable rod 203 will exhibit relative motion, forming a motion trajectory similar to expansion. 03 When moving, it will drive the correction plate 204 to move. As it moves, the correction plate 204 will gradually fit against one side of the outer wall of the base body 5. When the correction plate 204 moves to a certain position, the inclined surface of one side of the outer wall of the positioning plate 208 will touch the outer wall of the base body 5. Because one side of the outer wall of the positioning plate 208 is inclined, the positioning plate 208 will be moved. Since the outer wall of the positioning plate 208 is connected to the telescopic rod 205 and the spring 206, the positioning plate 208 will move against the front and back of the outer wall of the base body 5.

[0041] One end of the hose 302 is connected to and communicates with the outer compartment 301, and the other end of the hose 302 is connected to and communicates with the inner wall of the foot pedal 303.

[0042] In this embodiment, the worker places the chassis 201 at approximately the center of the base body 5, and then steps on the foot pedal 303. When the foot pedal 303 is stepped on, the liquid inside the foot pedal 303 will flow into the inner wall of the outer chamber 301. At this time, the liquid will flow into the inner wall of the outer chamber 301 through the hose 302. When the liquid enters the inner wall of the outer chamber 301, it will squeeze one end of the connecting rod 304. Because one end of the connecting rod 304 has the same diameter as the inner wall of the outer chamber 301, the connecting rod 304 will be pushed to move. When the connecting rod 304 is pushed to move, it will drive the rack 305 to move synchronously. When the rack 305 moves, it will drive the linkage gear 202 to rotate.

[0043] The inner walls of the outer compartment 301, hose 302, and foot pedal 303 are all filled with liquid; The outer compartment 301, hose 302, and foot pedal 303 are all interconnected.

[0044] In this embodiment, when the rack 305 moves, it drives the linkage gear 202 to rotate. When the linkage gear 202 rotates, its tooth groove meshes with the tooth groove of the movable rod 203, so the movable rod 203 will be driven to move. At this time, the movable rod 203 will exhibit relative motion, forming a motion trajectory similar to expansion. When the movable rod 203 moves, it will drive the straightening plate 204 to move. When the straightening plate 204 moves, it will gradually fit against one side of the outer wall of the base body 5. When the straightening plate 204 moves to a certain position, the inclined surface of one side of the outer wall of the positioning plate 208 will touch the outer wall of the base body 5. Because one side of the outer wall of the positioning plate 208 is inclined, the positioning plate 208 will be driven to move.

[0045] Working principle: When using this high-voltage electrical equipment precision installation device, such as... Figure 1 , Figure 2 , Figure 3 As shown, the straightening mechanism 2 and the control mechanism 3 need to be installed and debugged before the transformer body 1 is hoisted. The installation and debugging method is as follows: First, the staff needs to calibrate the correction mechanism 2 and the control mechanism 3 to ensure that they are centered on the base body 5 (because the dimensions of the base body 5 are matched with the dimensions of the bottom of the transformer base body 4). The staff places the chassis 201 approximately in the center of the base body 5, and then steps on the foot pedal 303. When the foot pedal 303 is subjected to pressure, the liquid inside the foot pedal 303 will flow towards the inner wall of the outer chamber 301. At this time, the liquid will flow into the inner wall of the outer chamber 301 through the hose 302. When the inner wall of the outer chamber 301 is pressed, one end of the connecting rod 304 will be squeezed. Since one end of the connecting rod 304 has the same diameter as the inner wall of the outer chamber 301, the connecting rod 304 will be pushed and moved. When the connecting rod 304 is pushed and moved, it will drive the rack 305 to move synchronously. When the rack 305 moves, it will drive the linkage gear 202 to rotate. When the linkage gear 202 rotates, its tooth groove meshes with the tooth groove of the movable rod 203, so the movable rod 203 will be driven to move. At this time, the movable rod 203 will exhibit relative motion and form a motion trajectory similar to expansion.

[0046] Secondly, when the movable rod 203 moves, it will drive the straightening plate 204 to move. When the straightening plate 204 moves, it will gradually fit against one side of the outer wall of the base body 5. When the straightening plate 204 moves to a certain position, the inclined surface of one side of the outer wall of the positioning plate 208 will touch the outer wall of the base body 5. Because one side of the outer wall of the positioning plate 208 is inclined, the positioning plate 208 will be moved. Since the outer wall of the positioning plate 208 is connected to the telescopic rod 205 and the spring 206, the positioning plate 208 will move against the front and back of the outer wall of the base body 5, causing the chassis 201 to move to a certain extent. After the chassis 201 moves, it means that the correction is completed. At this time, the staff can release their feet.

[0047] Afterwards, the staff operates a crane to transport the transformer body 1 to the base body 5 and gradually lowers the transformer body 1. When the transformer base body 4 at the bottom of the transformer body 1 is close to the top of the outer wall of the base body 5 (while the transformer body 1 is still suspended), the staff steps on foot pedal 303 again, repeating the above operation. At this time, one side of the outer wall of the straightening plate 204 will contact the bottom of the outer wall of the transformer base body 4 where it needs to be aligned with the base body 5. With the symmetrical pushing of the straightening plate 204, it will gradually calibrate the transformer base body 4, making the bottom of the transformer base body 4 aligned with the outer wall of the base body 5. Because the height of the straightening plate 204 and the top plate 207 is slightly higher than the height of the base body 5, the top plate 207 and the straightening plate 204 can provide auxiliary calibration for the transformer base body 4 during the subsequent lowering of the transformer body 1, making the transformer... The bottom of the transformer base body 4 is always in contact with the outer walls of the straightening plate 204 and the top plate 207. As the equipment is pressed down, the bottom of the transformer base body 4 will press against the top plate 207 and move downward until the bottom of the transformer base body 4 is in contact with the base body 5, and the installation is completed. After the installation is completed, the staff releases their foot, and the foot pedal 303 will reset (it has its own elastic reset component). After the foot pedal 303 resets, it will drive a certain amount of air through the hose 302 to create a negative pressure on the inner wall of the outer chamber 301. At this time, the negative pressure will drive the connecting rod 304 on the inner wall of the outer chamber 301 to reset. After the connecting rod 304 resets, it will drive the linkage gear 202 to reverse through the rack 305. At this time, the movable rod 203 and the straightening plate 204 will reset, so that their overall diameter is smaller than the diameter between the base bodies 5. Then the staff can remove the straightening mechanism 2 and the control mechanism 3 from the bottom of the transformer base body 4.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
