Description

Technical Field

[0001] The utility model belongs to the technical field of generator equipment manufacturing, in particular to a phase regulator rotor installation auxiliary tool. Background Art

[0002] A phase regulator is a device used to regulate and control the power factor in an electric power system. Its primary function is to provide reactive power support in power generation and transmission systems to ensure the stability and reliability of the power system. Phase regulators achieve this function through synchronous generators installed in the power grid. When the reactive power demanded by the grid is insufficient, the phase regulator can provide reactive power; conversely, when the grid has an excess of reactive power, the phase regulator can absorb reactive power. This flexibility helps improve the power system's power factor, reduce transmission losses, and alleviate the burden on power equipment, thereby improving overall power supply efficiency. Phase regulators are crucial in high-voltage transmission networks and large-scale power stations, especially as renewable energy sources such as wind and solar energy are gradually added to the grid.

[0003] The rotor of a condenser is a key component within the condenser. It typically consists of a rotor core, a rotating shaft, a commutator, and other components. Some also have fans for heat dissipation. During the motor rotor assembly process, the rotating shaft must be inserted into the center of the core, aligning them coaxially. The assembled rotor is then installed into the motor housing. Conventional technology typically uses a lifting mechanism to hoist the rotor into the condenser, allowing the rotor to be inserted into the condenser using its own gravity. During the hoisting process, the rotor's posture and position must be adjusted by tightening a steel cable. Therefore, prior to hoisting, it is crucial to ensure that the connection points between the steel cable and the rotor are accurate and secure. However, conventional methods typically involve placing the rotor directly on the ground in a designated area for hoisting, which can lead to difficulties connecting the rotor to the lifting mechanism. If the connection point between the steel cable and the rotor is misaligned, the rotor will tilt significantly after hoisting, making assembly difficult and impacting work efficiency and safety.

[0004] The patent with publication number CN115535833A discloses a lifting tool for passing the generator rotor through the generator. This lifting tool includes a crossbeam and two sets of traction tools. Among them, the traction tool on the left side adopts a structure of steel cable and hook, and the traction tool on the right side adopts a combination structure of screw rod and connecting rod. These two traction mechanisms can lift the rotor while laying it down, which can improve work efficiency to a certain extent. However, in the lifting tool of this structure, the traction tool on the right side cannot enter the interior of the phase regulator. Therefore, during assembly, there is actually only one set of traction tools working. Therefore, there will still be rotor tilt due to inaccurate connection points, which will affect the assembly of the rotor. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example:

[0029] A phase regulator rotor installation auxiliary tool, such as Figure 1 As shown, it includes a base plate 1, a support plate 6, a first lifting device 7, a clamping device 5, a placement plate 4 and a second lifting device 2.

[0030] The first lifting mechanism 7 is connected to both sides of the base plate 1. The support plate 6 is connected to the first lifting mechanism 7. The clamping mechanism 5 is connected to the support plate 6. The second lifting mechanism 2 is connected to the center of the base plate 1. The placement plate 4 is connected to the top of the second lifting mechanism 2. The first lifting mechanism 7 is used to lift and lower the support plate 6. The clamping mechanism 5 is used to clamp and secure the rotor core. The clamping mechanism 5 also rises and falls with the support plate 6. The second lifting mechanism 2 is used to lift and lower the placement plate 4, which is used to place the rotor body. The surface of the placement plate 4 can be made of wood to prevent damage to the rotor.

[0031] Sliding grooves 8 are provided on both sides of the base plate 1. Sliding blocks 9 are fixed on both sides of the first lifting device 7. The sliding blocks 9 are slidably connected in the sliding grooves 8. A bidirectional screw 24 is rotatably connected in the sliding groove 8 on at least one side. The first lifting devices 7 on both sides are respectively threadedly connected to the bidirectional screw 24 through the sliding blocks 9. One end of the bidirectional screw 24 is connected to the driving device. Further optimization, such as Figure 1 As shown, one end of the bidirectional screw rod 24 is connected to the connecting wheel 10. The driving device can use a motor, which is connected to the connecting wheel 10 via a pulley and a belt. The driving device is used to control the rotation of the bidirectional screw rod 24, thereby driving the first lifting device 7 to move closer to or away from each other, making it easier to clamp rotor cores of different sizes.

[0032] Specifically, before assembly, the rotor is transferred to the auxiliary fixture. A forklift or other lifting device can be used to lift the rotor onto the auxiliary fixture. The rotor is placed on the support plate 4. The height of the clamping device 5 is adjusted by adjusting the first lifting device 7, and the clamping device 5 is used to clamp the rotor's core. During this process, the drive device activates the bidirectional screw 24, driving the first lifting device 7 to move, facilitating the clamping device 5's grip on the core. To prepare for lifting and assembling the rotor, the lifting mechanism's steel cable must first be connected to the rotor, typically using a hook to ensure the cable is securely attached to the rotor at the designated location. During this process, the second lifting device 2 can be used to adjust the height of the support plate 4, facilitating cable connection. After determining the desired working height, the clamping device 5 is used to clamp the cable's core to the rotor's fixed position, allowing for easy cable connection. After connection is complete, the lifting device is activated to tighten the cable. The clamping device 5 is then opened, and the screws are controlled to move the first lifting devices 7 on both sides away from each other. After the first lifting device 7 separates, it is controlled to lower. The second lifting device 2 is controlled to slowly descend. During this process, the cable connection to the rotor is checked for stability. If any instability is detected, the second lifting device 2 is controlled to move upward, using the placement plate 4 to support the rotor. The rotor is then secured using the clamping device 5, and the cable is reconnected to the rotor. The clamping device 5 is opened, and the control screw drives the first lifting devices 7 on both sides away from each other. The second lifting device 2 is controlled to slowly descend until the placement plate 4 is completely clear of the rotor. The hoisting device hoists the rotor above the phase regulator and lowers it, completing assembly with the help of other auxiliary tools. This design allows for temporary placement of the rotor to be assembled. The adjustable first and second lifting devices 7 and 2 facilitate connection between the hoisting device and the rotor, facilitating subsequent hoisting and assembly of the rotor to accommodate the clamping requirements of different rotor models. This lifting design enables the clamping device 5 to precisely align with the rotor core, ensuring a secure and accurate clamping.

[0033] In this utility model, the design of the base plate 1 and support plate 6 provides a stable foundation and ensures the robustness of the entire fixture. The second lifting device 2 allows for precise positioning of the plate 4, facilitating rotor placement. The design of the first lifting device 7 and the bidirectional screw 24 facilitate adjustment of the position of the clamping device 5, facilitating rotor positioning. This auxiliary fixture of the utility model stably secures the rotor, facilitating rotor assembly preparation and improving rotor assembly efficiency.

[0034] In a preferred embodiment, Figure 2As shown, the first support device includes a mounting plate 19, a first hydraulic cylinder 18, and a position-limiting telescopic rod 17. The sliding block 9 is fixed to both sides of the mounting plate 19. The bottom of the first hydraulic cylinder 18 is fixed to the middle of the mounting plate 19, and the piston rod of the first hydraulic cylinder 18 is connected to the support plate 6. The position-limiting telescopic rod 17 is connected to both sides of the mounting plate 19, and the top of the position-limiting telescopic rod 17 is connected to the support plate 6. Further optimization is made, the position-limiting telescopic rod 17 includes an outer tube and an inner rod, one side of the inner rod slidingly connected to the outer tube; the bottom of the outer tube is connected to the mounting plate 19, and the top of the inner rod is connected to the support plate 6. The cooperation between the first hydraulic cylinder 18 and the position-limiting telescopic rod 17 ensures stable up and down movement of the support plate 6. Through this combined structure, the first support device not only provides strong support force and stability, but also has good adjustment flexibility, thus providing reliable guarantees for subsequent rotor clamping and assembly operations.

[0035] In a preferred embodiment, Figure 2 As shown, two limiting telescopic rods 17 are provided on both sides of the mounting plate 19. By designing the two limiting telescopic rods 17, the stability of the support plate 6 can be further guaranteed, so that the support plate 6 can be stably lifted and lowered.

[0036] In a preferred embodiment, the clamping device 5 includes a fixed plate 16, a connecting plate 15, a first clamping jaw 12, a second clamping jaw 14, a gear mechanism and a drive motor 11; wherein the fixed plate 16 is connected to the support plate 6, the connecting plate 15 is arranged on one side of the fixed plate 16, the gear mechanism is connected to the connecting plate 15, and the gear mechanism includes a driving gear 25, a first driven gear 26, a second driven gear 30 and a third driven gear 29; the driving gear 25 is rotatably connected to the connecting plate 15 and connected to the driving device, the first driven gear 26 is connected to the driving device, and the second driven gear 30 is connected to the driving device. Gear 26 and a second driven gear 30 are respectively meshed on either side of the driving gear 25 and are both rotationally connected to the connecting plate 15. A third driven gear 29 is rotationally connected to the connecting plate 15 and meshes with the second driven gear 30. The first clamping jaw 12 and the second clamping jaw 14 are both slidably connected to the top of the connecting plate 15. A first rack 27 is fixedly connected to the bottom of the first clamping jaw 12, and a second rack 28 is fixedly connected to the bottom of the second clamping jaw 14. The first rack 27 meshes with the first driven gear 26, and the second rack 28 meshes with the third driven gear 29. Specifically, during use, the driving motor 11 drives the driving gear 25 to rotate, which in turn drives the first driven gear 26 to rotate. The first driven gear 26, through its meshing with the rack, drives the first clamping jaw 12 to move. The driving gear 25 drives the second driven gear 30 to rotate, which in turn drives the third driven gear 29 to rotate. The third driven gear 29, through its meshing with the rack, drives the second clamping jaw 14 to move. The second driven gear 30 is provided to ensure that the third driven gear 29 rotates in the opposite direction to the first driven gear 26, which allows the first clamping jaw 12 and the second clamping jaw 14 to move closer to or further away from each other. This design ensures the efficiency and flexibility of the clamping device 5, allowing it to accommodate different models of rotor cores. The precise transmission of the gear mechanism also ensures stable clamping and release operations, thus ensuring the necessary accuracy and safety during the rotor assembly process.

[0037] In a preferred embodiment, Figure 1 as well as Figure 4 As shown, the connecting plate 15 is provided with two layers, and the gear mechanism is arranged between the two layers of connecting plates 15; the connecting plates 15 on both layers are connected to the fixed plate 16; a sliding bar is fixed to the top of the connecting plate 15, and the bottoms of the first clamping jaw 12 and the second clamping jaw 14 are both I-shaped structures. The first clamping jaw 12 and the second clamping jaw 14 are slidingly connected to the sliding bar through grooves on both sides of the bottom I-shaped structure. The design of the two-layer connecting plate 15 can improve the supporting capacity. Therefore, the connecting plate 15 also needs to be used to place the iron core of the rotor. Therefore, the provision of two layers of connecting plates 15 can effectively prevent the connecting plate 15 from being compressed and deformed. The design of the sliding bar and the I-shaped structure can ensure the stable movement of the first clamping jaw 12 and the second clamping jaw 14. This structural setting provides a good foundation for the operation of the clamping device 5 and plays an important role in the rotor assembly and clamping operations.

[0038] In a preferred embodiment, the fixing plate 16 is detachably connected to the support plate 6. By using bolts, buckles or other connecting parts, the fixing plate 16 and the support plate 6 can be easily disassembled and reassembled for easy maintenance and replacement of parts.

[0039] In a preferred embodiment, an anti-slip layer 13 is provided on the side where the first jaw 12 and the second jaw 14 are close to each other, and the anti-slip layer 13 includes a plurality of transverse stripes. This anti-slip design is intended to enhance the friction during the clamping process, thereby increasing the gripping force of the jaws on the rotor core, and ensuring that the rotor core can be effectively prevented from sliding or falling off during the clamping and transportation process, whether it is a horizontal operation or a vertical operation. The transverse stripe structure of the anti-slip layer 13 not only increases the friction coefficient between the contact surface between the jaws and the core, but also effectively disperses the contact pressure to prevent material damage caused by excessive pressure. This feature is particularly important during the clamping process, because the rotor core is often made of a relatively soft or smooth material. If there is insufficient friction, it may cause unstable clamping, thereby affecting the accuracy and safety of assembly.

[0040] In a preferred embodiment, Figure 3 As shown, the second lifting device 2 includes a mounting frame 21, a first bracket 22, a second bracket 23, and a second hydraulic cylinder 20. The mounting frame 21 is fixed to the base plate 1, and the first bracket 22 and the second bracket 23 are hingedly connected. One end of the first bracket 22 is hinged to the mounting frame 21, and the other end is slidably connected to the placement plate 4. The second bracket 23 is hinged to the placement plate 4 at one end and slidably connected to the mounting frame 21 at the other end. The bottom of the second hydraulic cylinder 20 is hinged to the second bracket 23, and the piston rod of the second hydraulic cylinder 20 is hinged to the first bracket 22. One end of the first bracket 22 is hinged to the mounting frame 21, and the other end is slidably connected to the placement plate 4, allowing the placement plate 4 to move vertically relative to the mounting frame 21 to accommodate operations at different heights. The advantage of this design is that it effectively increases the flexibility of the workspace and accommodates a variety of assembly and handling tasks. One end of the second bracket 23 is hinged to the placement plate 4, and the other end is slidably connected to the mounting frame 21, similarly ensuring that the placement plate 4 can be freely raised and lowered between different heights, improving overall operational convenience. The crucial second hydraulic cylinder 20 is fixed to the second bracket 23, with its base hinged to the second bracket 23, while the cylinder's piston rod is hinged to the first bracket 22. This design allows the hydraulic cylinder's force to be directly transmitted to the first bracket 22, thereby driving the raising and lowering of the placement plate 4. By controlling the movement of the hydraulic cylinder, the operator can precisely adjust the vertical position of the placement plate 4, thereby achieving precise clamping and placement of materials. This hydraulic lifting mechanism not only improves operational efficiency but also enhances overall safety and stability by reducing the complexity of manual operation.

[0041] In a preferred embodiment, Figure 1As shown, limit slots 3 are provided on the front and rear sides of the base plate 1, and a limit slider is fixed to the bottom of the first lifting support device, which is slidably connected in the limit slots 3. The design of the limit slots 3 and the limit slider is to ensure the stability of the movement of the first lifting device 7.
