Description

Technical Field

[0001] This invention relates to the field of exciter assembly and disassembly technology, and in particular to an exciter rotor assembly and disassembly device and a method for assembling and disassembling an exciter rotor. Background Technology

[0002] The exciter rotors and generator rotors used in nuclear power plants are mostly large and heavy, and are connected by pin sleeves. When it is necessary to separate or reassemble the exciter rotor and generator rotor, the pin sleeve is very small compared to the exciter rotor or generator rotor, and the weight distribution of the exciter rotor along its axial direction is uneven. Therefore, the pin sleeve is prone to being stressed and jammed during the separation or reassembly process, making the separation or reassembly process time-consuming and labor-intensive. At the same time, when the exciter rotor is separated from the generator rotor, the exciter rotor will swing up and down, which may collide with the central insulator of the generator, making the central insulator prone to damage. Summary of the Invention

[0003] Therefore, it is necessary to provide an exciter rotor disassembly and assembly device to address the problems of time-consuming and labor-intensive disassembly and reassembly of exciter rotors and generator rotors used in nuclear power plants, which are prone to damaging the insulators.

[0004] An exciter rotor disassembly and assembly device is used to disassemble or reassemble a mating exciter rotor and a generator rotor, comprising:

[0005] The weighing assembly includes a first weighing assembly and a second weighing assembly spaced apart along the axial direction of the exciter rotor; the first weighing assembly and the second weighing assembly respectively abut against different specific positions of the exciter rotor to work together to support different specific positions along the axial direction of the exciter rotor, and respectively detect the pressure value from the exciter rotor on each of them.

[0006] The first and second weighing components can move vertically to adjust the levelness of the exciter rotor.

[0007] In one embodiment, the first weighing component includes a first adjusting member and a first weighing instrument; the first adjusting member is connected to the first weighing instrument, and the first adjusting member can drive the first weighing instrument to move up and down in the vertical direction, thereby driving the exciter rotor to move up and down; and the first weighing instrument can weigh the exciter rotor and display a first pressure value; and / or

[0008] The second weighing component includes a second adjusting member and a second weighing instrument; the second adjusting member is connected to the second weighing instrument, and the second adjusting member can drive the second weighing instrument to move up and down in the vertical direction, so as to drive the exciter rotor to move up and down; and the second weighing instrument can weigh the exciter rotor and display a second pressure value.

[0009] In one embodiment, the first adjusting member and the second adjusting member are jacks.

[0010] In one embodiment, the exciter rotor disassembly and assembly device further includes a support beam, and the support beam is disposed between the weighing component and the exciter rotor;

[0011] The support beam is equipped with snap-fit ​​holes, and part of the exciter rotor can be snapped into the snap-fit ​​holes.

[0012] In one embodiment, the weighing component further includes at least two support rollers;

[0013] At least two of the support rollers are spaced apart and sleeved on the support beam, and at least two of the support rollers are rotatable relative to the support beam; when part of the exciter rotor is engaged with the engagement hole, it can abut against the wheel surface of at least two of the support rollers.

[0014] In one embodiment, the exciter rotor disassembly and assembly device further includes a frame, the frame having a receiving cavity, the weighing component being housed in the receiving cavity, and the side of the first adjusting member facing away from the first weighing instrument being connected to the frame, and the side of the second adjusting member facing away from the second weighing instrument being connected to the frame.

[0015] An adjustment groove extending along the height direction of the frame is formed on the side wall of the receiving cavity, and a slide rod is formed on the support beam within the adjustment groove. The slide rod can slide along the extension direction of the adjustment groove under the action of the first adjustment member and / or the second adjustment member.

[0016] In one embodiment, the exciter rotor disassembly and assembly device further includes a moving component mounted on the frame. The moving component includes a drive component and a wheel. The drive component is driven to the wheel, and the outer wheel surface of the wheel is used for rolling contact with the ground.

[0017] When the exciter rotor is detached from or reattached to the generator rotor, the wheels can drive the frame to move under the drive of the drive component, so that the exciter rotor moves closer to or further away from the generator rotor.

[0018] In one embodiment, the exciter rotor disassembly and assembly device further includes an alignment component connected to the frame;

[0019] When the exciter rotor is reinstalled onto the generator rotor, the alignment assembly is used to axially align the exciter rotor with the generator rotor.

[0020] In one embodiment, the exciter rotor disassembly and assembly device further includes a second adjustment component, which is connected to the side of the weighing component away from the exciter rotor; the second adjustment component can drive the weighing component to move along its own width direction.

[0021] The present invention also provides a method for disassembling and assembling an exciter rotor, which is based on the exciter rotor disassembly and assembly device described in any of the above embodiments and can solve at least one of the above technical problems.

[0022] The exciter rotor disassembly and assembly method provided by the present invention includes:

[0023] The exciter rotor is respectively abutted against the first weighing component and the second weighing component at different specific positions along its axial direction;

[0024] The first pressure value received by the first weighing component from the exciter rotor and the second pressure value received by the second weighing component from the exciter rotor are obtained.

[0025] The first weighing component and the second weighing component are moved vertically until the first pressure value is equal to the first preset value and the second pressure value is equal to the second preset value.

[0026] The aforementioned exciter rotor disassembly and assembly device and method, when it is necessary to separate or reassemble the cooperating exciter rotor and generator rotor, firstly, the first and second weighing components, which are spaced apart along the axial direction of the exciter rotor, abut against different specific positions on the exciter rotor. This allows the first and second weighing components to work together to support different specific positions on the axial direction of the exciter rotor, and the pressure value from the exciter rotor is detected at each position. Then, based on the detected pressure value, the first and second weighing components move vertically, thereby moving their respective supported portions of the exciter rotor vertically to adjust the levelness of the exciter rotor. This ensures a high levelness of the exciter rotor when it is separated from or reassembled relative to the generator rotor, preventing the pin sleeve from being stressed and jammed during the process, making the entire disassembly or reassembly process time-saving and labor-saving. Simultaneously, the support of the frame prevents the exciter rotor from swinging up and down, thus reducing the possibility of collision between the exciter rotor and the generator's central insulator, which could damage the central insulator.

[0039] See Figures 1-3 and Figure 5 , Figure 1 A front view of an exciter rotor disassembly and assembly device according to an embodiment of the present invention is shown; Figure 2 It shows Figure 1 The top view of the exciter rotor disassembly and assembly device shown; Figure 3 It shows Figure 1 The left view of the exciter rotor disassembly and assembly device shown; Figure 5 A schematic diagram of the exciter rotor 810 and generator rotor 820 after they are assembled together is shown.

[0040] It should be noted that you should refer to [link / reference]. Figure 5 When the exciter rotor 810 and the generator rotor 820 are engaged, their axial end faces, which are close to each other, are connected by a plurality of engaging bolts 840 spaced circumferentially along the exciter rotor 810. Each engaging bolt 840 has a pin sleeve 830 fitted around its outer circumference, which engages with the exciter rotor 810 and the generator rotor 820. Specifically, the end face of the exciter rotor 810 near the generator rotor 820 has a first engaging groove 811, and the end face of the generator rotor 820 near the exciter rotor 810 has a second engaging groove 821. A portion of the pin sleeve 830 is accommodated in the first engaging groove 811, and another portion is accommodated in the second engaging groove 821. One end of the engaging bolt 840 passes through the exciter rotor 810 and the pin sleeve 830 from the end face of the exciter rotor 810 facing away from the generator rotor 820, and finally connects to the generator rotor 820. Because the pin sleeve 830 is relatively thin and has a high fitting accuracy with the groove walls of the first locking groove 811 and the second locking groove 821, when the exciter rotor 810 is separated from the generator rotor 820, if the parallelism of the exciter rotor 810 and the generator rotor 820 is slightly different, the pin sleeve 830 will bear the weight and get stuck, making the whole separation process very time-consuming and laborious.

[0041] In one specific embodiment, the exciter rotor 810 has a diameter of 1850 mm and a weight of 9 tons. The weight distribution of the exciter rotor 810 along its own axial direction is uneven, with the front half near the generator rotor 820 weighing 7 tons and the rear half away from the generator rotor 820 weighing 2 tons. The mounting surface of the generator rotor 820, which mates with the exciter rotor 810, is 1095 mm. The pin sleeve 830 has a diameter of 95 mm, and the fitting accuracy between the pin sleeve 830 and the exciter rotor 810 and the generator rotor 820 is 0.03 mm.

[0042] When separating the exciter rotor 810 from the generator rotor 820, which are installed together, the large diameter, heavy weight, and uneven weight distribution of the exciter rotor 810 make it difficult to precisely control its horizontality using slings. This causes the pin sleeve 830 to easily become stuck under the weight during separation, making the entire separation process very time-consuming and labor-intensive. Furthermore, when the exciter rotor 810 separates from the generator rotor 820, it is also prone to swinging up and down along its own axis under the influence of the slings. Specifically, the axial direction of the exciter rotor 810 is... Figure 3 and Figure 5 The exciter rotor 810 collides with the generator's central insulator in the yy' direction, causing damage to the central insulator. Therefore, each time the exciter rotor 810 needs to be separated from the generator rotor 820, it requires eight people working together and takes eight hours to complete.

[0043] Based on the aforementioned problems, this invention provides an exciter rotor disassembly and assembly device for separating or reassembling the cooperating exciter rotor 810 and generator rotor 820. The device includes a weighing assembly 200, which comprises a first weighing assembly 210 and a second weighing assembly 220 spaced apart along the axial direction of the exciter rotor 810. Specifically, the axial direction of the exciter rotor 810 is... Figure 3 and Figure 5 The first and second weighing components 210 and 220 respectively abut against different specific positions of the exciter rotor 810 to jointly support different specific positions of the exciter rotor 810 in the axial direction and detect the pressure value from the exciter rotor 810 on each position; the first and second weighing components 210 and 220 can move in the vertical direction, specifically, the vertical direction is... Figure 1 The zz' direction is adjusted to adjust the levelness of the exciter rotor 810.

[0044] When the exciter rotor 810 and generator rotor 820 are disassembled or reassembled using the aforementioned exciter rotor disassembly and assembly device, the first and second weighing components 210 and 220, which are spaced apart along the axial direction of the exciter rotor 810, are first brought into contact with different specific positions on the exciter rotor 810. This allows the first and second weighing components 210 and 220 to work together to support different specific positions on the axial direction of the exciter rotor 810, and the pressure values ​​from the exciter rotor 810 on each component are detected. Then, based on the detected pressure values, the first and second weighing components 210 and 220 are moved vertically, thereby moving their respective supported portions of the exciter rotor 810 vertically to adjust the levelness of the exciter rotor 810. This ensures that the exciter rotor 810 maintains a high level of horizontality when being disassembled or reassembled relative to the generator rotor 820, thus preventing the pin sleeve 830 from being stressed and jammed during the process, making the entire disassembly or reassembly process time-saving and labor-saving. Simultaneously, the support provided by the frame 100 prevents the exciter rotor 810 from swinging up and down, thereby reducing the possibility of collision between the exciter rotor 810 and the generator's central insulator and damage to the central insulator. When disassembling the cooperating exciter rotor 810 and generator rotor 820 using this exciter rotor disassembly and reassembly device, only three people are needed to complete the process in one hour. Compared to the original disassembly method, efficiency is greatly improved, and the entire disassembly process is also safer.

[0045] It should be noted that, since the exciter rotor 810 is relatively heavy and its weight distribution is uneven, when the exciter rotor 810 is supported by the first weighing component 210 and the second weighing component 220 each time, the support must be placed at the same specific position to ensure that when the first weighing component 210 and the second weighing component 220 move vertically and the pressure value they receive meets the preset conditions, the entire exciter rotor 810 is in a horizontal position.

[0046] The following is a detailed description of the structure of the exciter rotor disassembly and assembly device. Please refer to [link / reference needed]. Figure 1 and Figure 3The first weighing component 210 of the exciter rotor disassembly and assembly device provided in one embodiment of the present invention includes a first adjusting member 211 and a first weighing instrument 212. The first adjusting member 211 is connected to the first weighing instrument 212, and the first adjusting member 211 can drive the first weighing instrument 212 to move closer to or further away from the exciter rotor 810. The first adjusting member 211 drives the first weighing instrument 212 to move up and down in the vertical direction, thereby driving the exciter rotor 810 to move up and down. The first weighing instrument 212 can weigh the exciter rotor 810 and display a first pressure value. The magnitude of the weighing data detected by the first weighing instrument 212 causes the first adjusting member 211 to drive the first weighing instrument 212 to move up and down in the vertical direction, thereby causing the portion of the exciter rotor 810 supported by the first weighing instrument 212 to move in the vertical direction, ultimately causing a change in the levelness of the exciter rotor 810.

[0047] In one specific embodiment, when the first pressure value measured by the first weighing instrument 212 is not equal to the first preset value, the first adjusting member 211 drives the first weighing instrument 212 to rise or fall, thereby causing the part of the exciter rotor 810 it supports to rise or fall, thus changing the levelness of the exciter rotor 810 until the first weighing quantity equals the first preset value. Specifically, if the first pressure value is less than the first preset value, the first adjusting member 211 drives the first weighing instrument 212 to rise; if the first pressure value is greater than the first preset value, the first adjusting member 211 drives the first weighing instrument 212 to fall.

[0048] In one specific embodiment, the first adjusting member 211 is a jack, which drives the first weighing instrument 212 to rise or fall, which is very simple and convenient. Of course, in other embodiments, the first adjusting member 211 can also be a cooperating guide rail slider, gear rack, or worm gear, etc., without special limitation. In one specific embodiment, the first weighing instrument 212 is a weight sensor.

[0049] Please see Figure 3 The second weighing component 220 of the exciter rotor disassembly and assembly device provided in one embodiment of the present invention includes a second adjusting member 221 and a second weighing instrument 222. The second adjusting member 221 is connected to the second weighing instrument 222. The second adjusting member 221 can drive the second weighing instrument 222 to move up and down in the vertical direction, thereby driving the exciter rotor 810 to move up and down. The second weighing instrument 222 can weigh the exciter rotor 810 and display a second pressure value. The magnitude of the weighing data detected by the second weighing instrument 222 causes the second adjusting member 221 to drive the second weighing instrument 222 to move up and down in the vertical direction, thereby causing the portion of the exciter rotor 810 supported by the second weighing instrument 222 to move in the vertical direction, ultimately causing a change in the levelness of the exciter rotor 810.

[0050] In one specific embodiment, when the second pressure value measured by the second weighing instrument 222 is not equal to the second preset value, the second adjusting member 221 drives the second weighing instrument 222 to rise or fall, thereby causing the portion of the exciter rotor 810 it supports to rise or fall, thus changing the levelness of the exciter rotor 810 until the second weighing quantity equals the second preset value. Specifically, if the second pressure value is less than the second preset value, the second adjusting member 221 drives the second weighing instrument 222 to rise; if the second pressure value is greater than the second preset value, the second adjusting member 221 drives the second weighing instrument 222 to fall.

[0051] In one specific embodiment, the exciter rotor 810 weighs 9 tons, with the front half near the generator rotor 820 weighing 7 tons and the rear half away from the generator rotor 820 weighing 2 tons. Therefore, the first preset value is 7 tons, and the second preset value is 2 tons. It should be noted that there are no limitations on the values ​​of the first and second preset values; they are adaptively modified according to the positions of the first weighing instrument 212 and the second weighing instrument 222 abutting against the support, as well as the different weight distribution and weight of the exciter rotor 810 itself.

[0052] In one specific embodiment, the second adjusting member 221 is a jack, which drives the second weighing instrument 222 to move relative to the exciter rotor 810, which is very simple and convenient. Of course, in other embodiments, the second adjusting member 221 can also be a cooperating guide rail slider, gear rack, or worm gear, etc., without special limitation. In one specific embodiment, the second weighing instrument 222 is a weight sensor.

[0053] Please see Figure 1 An embodiment of the exciter rotor disassembly and assembly device provided by the present invention further includes a frame 100, which has a receiving cavity 110. A weighing assembly 200 is housed within the receiving cavity 110. A first adjusting member 211 is connected to the frame 100 on the side opposite to the first weighing instrument 212, and a second adjusting member 221 is connected to the frame 100 on the side opposite to the second weighing instrument 222, so that a portion of the exciter rotor 810 is also housed within the receiving cavity 110. Through the limiting effect of the sidewall of the receiving cavity 110, the exciter rotor 810 is less likely to slide relative to the first weighing instrument 212 or the second weighing instrument 222 after contact with them, thereby ensuring more accurate measurements by the first weighing instrument 212 and the second weighing instrument 222.

[0054] In one specific embodiment, because it is necessary to ensure that the first weighing instrument 212 and the second weighing instrument 222 abut against specific positions of the exciter rotor 810, the distance between the two side walls of the receiving cavity 110 arranged in the front-rear direction of the frame 100 is set to be equal to the thickness in the axial direction of the exciter rotor 810. Specifically, the front-rear direction of the frame 100 is... Figure 1 The direction of xx' in the middle. In this way, when the exciter rotor 810 is housed in the receiving cavity 110, since the positions of the first weighing instrument 212 and the second weighing instrument 222 in the front-rear direction of the frame 100 are fixed, it is possible to determine the specific position where the first weighing instrument 212 and the second weighing instrument 222 abut against and support the exciter rotor 810.

[0055] Of course, in other embodiments, the distance between the two side walls of the receiving cavity 110 arranged along the front-rear direction of the frame 100 can also be set to a preset value greater than the thickness of the exciter rotor 810 in the axial direction. When the exciter rotor 810 is housed in the receiving cavity 110, the distance between the two end faces of the exciter rotor 810 along its axial direction and the side walls of the receiving cavity 110 is adjusted to the corresponding preset value, thereby ultimately causing the first weighing instrument 212 and the second weighing instrument 222 to abut and support at a specific position on the exciter rotor 810. For example, when the distance between the two side walls of the receiving cavity 110 along the front-rear direction of the frame 100 is greater than the axial thickness of the exciter rotor (0.5 meters), each time the exciter rotor 810 is installed or removed, adjusting the distance between the end face of the exciter rotor 810 near the generator rotor 820 and the side wall of the receiving cavity 110 to 0.5 meters will allow the first weighing instrument 212 and the second weighing instrument 222 to abut and be supported at a specific position on the exciter rotor 810. Of course, in other embodiments, this preset value can also be set to 0.2 meters or 0.8 meters, etc., without special limitation.

[0056] Please see Figures 1-3 An embodiment of the exciter rotor disassembly and assembly device provided by the present invention further includes a support beam 300, which is disposed between the weighing component 200 and the exciter rotor 810. The support beam 300 is configured with snap-fit ​​holes 310, and a portion of the exciter rotor 810 can be snapped into the snap-fit ​​holes 310. By providing the support beam 300 with snap-fit ​​holes 310, a portion of the exciter rotor 810 can be snapped into the snap-fit ​​holes 310, thereby enabling the support beam 300 to provide surface and line support for the exciter rotor 810, increasing the contact area between the support beam 300 and the exciter rotor 810, and making the exciter rotor 810 more stable when installed on the frame 100. Optionally, the support beam 300 is housed within the receiving cavity 110.

[0057] Please see Figure 1 and Figure 2 The weighing component 200 of the exciter rotor disassembly and assembly device provided in one embodiment of the present invention further includes at least two support rollers 400; the at least two support rollers 400 are spaced apart and sleeved on the support beam 300, and the at least two support rollers 400 are rotatable relative to the support beam 300; when part of the exciter rotor 810 is engaged in the engagement hole 310, it can abut against the wheel surface of the at least two support rollers 400. By setting the support rollers 400, the friction between the support beam 300 and the exciter rotor 810 becomes rolling friction, and the friction between the two is small. This not only reduces the scratching of the outer surface of the exciter rotor 810, but also makes it easier for the exciter rotor 810 to engage and disengage from the hole wall of the engagement hole 310 when part of the exciter rotor 810 is engaged in or disengaged from the engagement hole 310, because the sliding friction is changed to rolling friction.

[0058] In one specific embodiment, there are four support rollers 400, which are located at the four corners of the support beam 300. It should be noted that the number of support rollers 400 is not specifically limited and can be adjusted according to the stress on the support rollers 400 and the weight of the exciter rotor 810.

[0059] Please see Figure 4 , Figure 4 It shows Figure 1 The enlarged view at point A is shown. An embodiment of the exciter rotor disassembly and assembly device provides an adjustment groove 410 extending along the height direction of the frame 100 on the side wall of the receiving cavity 110. Specifically, the height direction of the frame 100 is... Figure 4 In the zz' direction, a slide bar is formed on the support beam 300 and is provided in the adjustment groove 410. The slide bar can slide along the extension direction of the adjustment groove 410 under the drive of the first adjustment member 211 and / or the second adjustment member 221, so that the first adjustment member 211 and the second adjustment member 221 always move up and down along the height direction of the frame 100.

[0060] Because the sidewall of the receiving cavity 110 is constructed with an adjustment groove 410 extending along the height direction of the frame 100, when the levelness of the exciter rotor 810 is adjusted by the first adjustment member 211 and / or the second adjustment member 221, the slide bar of the support beam 300 can slide along the extension direction of the adjustment groove 410, thereby enabling the support beam 300 to move the first weighing instrument 212 and the second weighing instrument 222 closer to or further away from the exciter rotor 810. In one specific embodiment, the slide bar of the support beam 300 can slide along the extension direction of the adjustment groove 410 under the action of the first adjustment member 211. In another specific embodiment, the slide bar of the support beam 300 can slide along the extension direction of the adjustment groove 410 under the action of the second adjustment member 221. In yet another embodiment, the slide bar of the support beam 300 can slide along the extension direction of the adjustment groove 410 under the combined action of the first adjustment member 211 and the second adjustment member 221.

[0061] Please see Figure 1 An embodiment of the exciter rotor disassembly and assembly device provided by the present invention further includes a second adjustment component 500, which is connected to the side of the weighing component 200 away from the exciter rotor 810; the second adjustment component 500 can drive the weighing component 200 to move along the length direction of the frame 100, specifically, the length direction of the frame 100 is... Figure 1 The direction of xx' in the middle.

[0062] Because the outer peripheral surface of the exciter rotor 810 is curved, when part of the exciter rotor 810 is housed in the receiving cavity 110 and comes into contact with the first weighing instrument 212 or the second weighing instrument 222, the contact area with the curved surface may be small, or even non-contacting. This will inevitably affect the weighing effect of the first weighing instrument 212 or the second weighing instrument 222. By using the second adjusting component 500 to move the weighing component 200 along the length of the frame 100, the position of the first weighing instrument 212 or the second weighing instrument 222 is changed, so that the first weighing instrument 212 and the second weighing instrument 222 make better contact with the outer peripheral surface of the exciter rotor 810, thereby achieving a better weighing effect.

[0063] In one specific embodiment, the second adjustment component 500 is a left-right adjustment screw, which includes two support beams and one adjustment screw. The two support beams are respectively disposed on both sides of the first weighing component 210 along the length direction of the frame 100. The adjustment screw passes through the first adjusting member 211, and both ends of the adjustment screw are connected to the support beams. By rotating the adjustment screw, the first adjusting member 211 can be moved along the length direction of the frame 100, thus achieving adjustment. Of course, a second adjustment component 500 is also provided on the second weighing component 220, and its adjustment principle is the same as described above, so it will not be described again.

[0064] Please see Figure 1 An embodiment of the exciter rotor disassembly and assembly device provided by the present invention further includes a moving component 600, which is mounted on the frame 100. The moving component 600 includes a drive member 610 and a wheel 620. The drive member 610 is driven to connect with the wheel 620, and the outer wheel surface of the wheel 620 is used to roll to connect with the ground. When the exciter rotor 810 is disassembled or reassembled from the generator rotor 820, the wheel 620 can drive the frame 100 to move under the drive of the drive member 610, so that the exciter rotor 810 moves closer to or further away from the generator rotor 820.

[0065] By setting up a movable component 600, the frame 100 is moved, thereby causing the exciter rotor 810 to move closer to or further away from the generator rotor 820, thus realizing the separation or reassembly of the exciter rotor 810 and the generator rotor 820. In one specific embodiment, the drive component 610 is a motor; however, in other embodiments, the drive component 610 can also be a cylinder.

[0066] Please see Figure 1 In one embodiment of the present invention, the moving component 600 has four wheels 620, which are respectively disposed at the four corners of the frame 100. The moving component 600 also includes a rotating shaft 640, a driving member 610 is drivenly connected to the rotating shaft 640, and the rotating shaft 640 is drivenly connected to the four wheels 620. When the driving member 610 drives the rotating shaft 640 to rotate around its own rotation axis, the rotating shaft 640 can drive the four wheels 620 to rotate synchronously, thereby enabling the frame 100 to move.

[0067] Please see Figure 1 The movable component 600 provided in one embodiment of the present invention further includes a support block 630, which is installed on the side of the frame 100 away from the receiving cavity 110, and the support block 630 is telescopic relative to the ground. When the frame 100 does not need the wheels 620 to move it, the support block 630 can support and fix the frame 100 on the ground, preventing the frame 100 from sliding at will and making it safer.

[0068] In one embodiment, the exciter rotor disassembly and assembly device further includes a centering component connected to the frame 100. When the exciter rotor 810 is reassembled to the generator rotor 820, the centering component is used to make the exciter rotor 810 and the generator rotor 820 axially aligned, thus making the reassembly process of the exciter rotor 810 more time-saving and convenient.

[0069] The present invention also provides a method for disassembling and assembling an exciter rotor, which is based on the exciter rotor disassembly and assembly device described in any of the above embodiments. The method for disassembling and assembling the exciter rotor includes:

[0070] The magnetic rotor 810 is brought into contact with the first weighing component 210 and the second weighing component 220 at different specific positions along its axial direction.

[0071] When it is necessary to remove or reinstall the exciter rotor 810, different specific positions on the axial direction of the exciter rotor 810 abut against the first weighing component 210 and the second weighing component 220, respectively.

[0072] The first pressure value received by the first weighing component 210 from the exciter rotor 810 and the second pressure value received by the second weighing component 220 from the exciter rotor 810 are obtained.

[0073] The pressure values ​​from the exciter rotor 810 are detected by the first weighing component 210 and the second weighing component 220, respectively, and the first pressure value received by the first weighing component 210 and the second pressure value received by the second weighing component 220 are obtained.

[0074] Move the first weighing component 210 and the second side weighing component vertically until the first pressure value equals the first preset value and the second pressure value equals the second preset value.

[0075] The first pressure value is compared with a first preset value, and the second pressure value is compared with a second preset value. If the first pressure value is less than the first preset value, the first weighing component 210 moves upward in the vertical direction; if the first pressure value is greater than the first preset value, the first weighing component 210 moves downward in the vertical direction. If the second pressure value is less than the second preset value, the second weighing component 220 moves upward in the vertical direction; if the second pressure value is greater than the second preset value, the second weighing component 220 moves downward in the vertical direction. This continues until the first pressure value equals the first preset value and the second pressure value equals the second preset value, thus adjusting the levelness of the exciter rotor 810.

[0076] When it is necessary to separate the exciter rotor 810 and generator rotor 820, which are installed together, first adjust the level of the exciter rotor 810 using the method described above. After adjustment, install the mounting screw 850 and use the electric wrench 700 to move the mounting screw 850 along... Figure 5 The exciter rotor 810 moves from the y direction to the y' direction so that the mounting screw 850 pushes the exciter rotor 810 out relative to the generator rotor 820 until the pin sleeve 830 comes off; at this time, the frame 100 is driven away from the generator rotor 820 by the drive component 610 until the exciter rotor 810 is separated from the central insulator of the generator.

[0077] Because the exciter rotor 810 maintains a high level of horizontality during this process, the pin sleeve 830 is effectively prevented from being stressed and jammed, making the entire disassembly process time-saving and labor-saving. Simultaneously, the support provided by the frame 100 prevents the exciter rotor 810 from swinging up and down along its axial direction, thereby reducing the possibility of collision between the exciter rotor 810 and the generator's central insulator, which could damage the central insulator. It should be noted that there are four mounting screws 850 installed on the exciter rotor 810, therefore there are also four electric wrenches 700, and the four electric wrenches can synchronously drive the four mounting screws 850 to move from the y-direction to the y' direction.

[0078] When the disassembled exciter rotor 810 needs to be reinstalled onto the generator rotor 820, the level of the exciter rotor 810 is first adjusted using the method described above. After adjustment, a dedicated alignment device is used to align the exciter rotor 810 with the center insulator of the generator. Then, the drive unit 610 drives the frame 100 to approach the generator rotor 820 until the exciter rotor 810 contacts and is fitted onto the pin sleeve 830. At this point, an electric wrench 700 is used to install the engagement bolt 840 between the exciter rotor 810 and the generator rotor 820. During this reinstallation process, the pin sleeve 830 is prevented from being stressed and jammed, making the entire reinstallation process time-saving and labor-saving.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
