In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0026] As shown in FIG1 , an embodiment of the present application provides an exciter rotor disassembly and assembly system, which includes a generator rotor 1, an exciter rotor 2, a connector 3 (as shown in FIG2 ) and a top support 4 (as shown in FIG2 ), as well as an exciter rotor disassembly and assembly wrench 5 and a controller. The connector 3 is provided on the exciter rotor 2, and extends into the generator rotor 1 after axially passing through the exciter rotor 2. The connector 3 is used to fix the exciter rotor 2 and the generator rotor 1 together to achieve the installation of the exciter rotor. The top support 4 is provided on the exciter rotor 2, and abuts against the generator rotor 1 after axially passing through the exciter rotor 2. The top support 4 is used to push out the exciter rotor 2 with the generator rotor 1 as support to achieve the disassembly of the exciter rotor 2. The exciter rotor disassembly wrench 5 is arranged on the side of the exciter rotor 2 away from the generator rotor 1. The exciter rotor disassembly wrench 5 is connected to the connecting member 3 or the top support member 4, and is used to drive the connecting member 3 or the top support member 4 to move axially to install or separate the generator rotor 1 and the exciter rotor 2. The controller is electrically connected to the exciter rotor disassembly wrench 5, and the controller is used to control the wrench to output power at a preset speed.

[0027] In the embodiment disclosed in the present application, the connecting member 3 may be a bolt, and the supporting member 4 may be a screw rod, a lead screw, etc.

[0028] The exciter rotor 2 is provided with a plurality of pin holes, which are evenly spaced along the circumferential direction of the exciter rotor 2. Each pin hole penetrates the exciter rotor 2 axially, and each pin hole includes a first circular hole and a second circular hole. The diameter of the first circular hole is larger than that of the second circular hole. The first circular hole is closer to the generator rotor 1 in the axial direction, and the second circular hole is farther away from the generator rotor 1 in the axial direction. The generator rotor 1 is provided with a plurality of pin sleeves, which are evenly spaced along the circumferential direction of the generator rotor 1 and correspond to the plurality of pin holes one by one. Specifically, the pin sleeve is accommodated in the first circular hole, and the second circular hole is used for the connector 3 to pass from the side away from the generator rotor 1 to the inside of the pin sleeve to realize the connection between the exciter rotor 2 and the generator rotor 1. Furthermore, the exciter rotor 2 is provided with a screw hole a, which penetrates the exciter rotor 2 axially, and is used for the top support 4 to pass through until it abuts against the end surface of the generator rotor 1.

[0029] The exciter rotor disassembly system of the present application includes two working conditions: installation and disassembly of the exciter rotor 2. For example, in the installation condition, the pin hole is aligned with the pin sleeve, the connector 3 is passed through the second circular hole into the pin sleeve, and the exciter rotor disassembly wrench 5 is installed on the exciter rotor 2. The installed exciter rotor disassembly wrench 5 can be sleeved on the periphery of the connector 3, and then the wrench drives the connector 3 to rotate, so that the connector 3 is screwed into the pin sleeve and the generator rotor 1, and at the same time, the exciter rotor 2 will move in the direction close to the generator rotor 1 until the pin sleeve is completely embedded in the pin hole, and the installation of the exciter rotor 2 is completed. In the disassembly condition, the top support member 4 is passed through the screw hole a until it contacts the end face of the generator rotor 1, and the exciter rotor disassembly wrench 5 is installed on the exciter rotor 2. The installed exciter rotor disassembly wrench 5 can be sleeved on the outer periphery of the top support member 4, and then the wrench drives the top support member 4 to rotate. At the same time, the top support member 4 can push the exciter rotor 2 out relative to the generator rotor 1 until the pin sleeve is completely separated from the pin hole, thus completing the disassembly of the exciter rotor 2. Of course, before disassembling the exciter rotor 2, the connector 3 needs to be screwed out of the pin sleeve for subsequent disassembly.

[0030] As shown in combination with FIG. 2 and FIG. 3 , the exciter rotor disassembly wrench 5 includes: a base 10, a driving member 20 and two actuators 30 (A) and 30 (B). The base 10 serves as a support carrier for the driving member 20 and the actuator 30, and is used to provide an assembly space for the driving member 20 and the actuator 30. The driving member 20 and the actuator 30 are both arranged on the base 10, and the driving member 20 is transmission-connected between the two actuators 30. The driving member 20 is used to drive the two actuators 30 to rotate. Specifically, in the installation condition, the actuator 30 (A) is used for detachable connection with the connecting member 3. At this time, the driving member 20 drives the connecting member 3 to rotate through the actuator 30 (A); in the disassembly condition, the actuator 30 (B) is used for detachable connection with the top support member 4. At this time, the driving member 20 drives the top support member 4 to rotate through the actuator 30 (B). That is, under the action of the driving member 20, the actuator 30 (A) applies a force to the connecting member 3, so that the connecting member 3 can rotate synchronously with the actuator 30 (A), or the actuator 30 (B) applies a force to the supporting member 4, so that the supporting member 4 can rotate synchronously with the actuator 30 (B). It can be understood that although the connecting member 3 and the supporting member 4 are shown in Figure 3 at the same time, only one of them will appear during the actual disassembly and assembly process.

[0031] For example, when installing the exciter rotor 2, the connector 3 is installed in the pin hole b of the exciter rotor 2, and then the wrench is installed on the exciter rotor 2. When the wrench is installed, the actuator 30 (A) cooperates with the connector 3, and the actuator 30 is driven to rotate by the driving member 20, driving the connector 3 to rotate synchronously, so that the connector 3 can be screwed into the pin sleeve. When disassembling the exciter rotor 2, the connector 3 is first removed from the exciter rotor 2 and the generator rotor 1, and then the top support 4 is installed in the screw hole a on the exciter rotor 2 and abutted against the end face of the generator rotor 1, and finally the wrench is installed on the exciter rotor 2. When the wrench is installed, the actuator 30 (B) can cooperate with the top support 4, and the actuator 30 is driven to rotate by the driving member 20, driving the top support 4 to rotate, so that the top support 4 can push the exciter rotor 2 out relative to the generator rotor 1.

[0032] The base 10 includes a first plate portion 11, a second plate portion 12 and a connecting portion 13. The first plate portion 11 and the second plate portion 12 are arranged opposite to each other, and the connecting portion 13 is connected between the first plate portion 11 and the second plate portion 12. In the embodiment disclosed in the present application, the driving member 20 is arranged on a side of the first plate portion 11 away from the second plate portion 12, and the actuator 30 is arranged between the first plate portion 11 and the second plate portion 12. Of course, in other embodiments, the driving member 20 may also be arranged between the first plate portion 11 and the second plate portion 12, and the actuator 30 may also be arranged on a side of the first plate portion 11 away from the second plate portion 12. It can be understood that the layout positions of the driving member 20 and the actuator 30 relative to the base 10 are not limited, as long as the two can achieve corresponding functions.

[0033] The first plate portion 11 and the second plate portion 12 are provided with through holes at positions corresponding to the connection portion 13, and bolts are passed through the two through holes and the connection portion 13, and nuts are tightened onto the bolts to achieve the fixation of the first plate portion 11 and the second plate portion 12. It can be understood that the height of the connection portion 13 is the same as the spacing between the first connection portion 13 and the second connection portion 13.

[0034] The driving member 20 includes a driving portion 21 and a transmission portion 22. The output end of the driving portion 21 is connected to the transmission portion 22, and the two ends of the transmission portion 22 are respectively rotatably connected to the first plate portion 11 and the second plate portion 12. The driving portion 21 is used to drive the transmission portion 22 to rotate relative to the base 10, and the transmission portion 22 is in transmission connection with the actuator 30. The transmission portion 22 is used to transmit the driving force of the driving portion 21 to the actuator 30, so that the actuator 30 can rotate relative to the base 10.

[0035] In the embodiment disclosed in the present application, the drive unit 21 is electrically driven. For example, the drive unit 21 can be a motor, specifically a double-insulated single-phase series-excited motor. At the same time, the drive unit 21 is also equipped with a reduction structure. The double-insulated single-phase series-excited motor and the reduction structure are small in size, light in weight, safe and reliable, and adopt a static torsion structure. The operation is smooth, vibration-free, impact-free, and noise-free. The operator is not affected by the reaction torque, the labor intensity is low, and the rated voltage is 220V50 / 60Hz.

[0036] Furthermore, the driving part 21 is electrically connected to the controller, and the controller can control the driving part 21 to drive the transmission part 22 to rotate at a preset speed. The driving member 20 of the present application operates in a speed-torque mode, maintains a preset speed value during movement, and stops when the torque reaches the set torque. Driving the actuator 30 to rotate at a precise speed and torque can screw the connecting member 3 into the pin sleeve more safely and smoothly, and can enable the supporting member 4 to push out the exciter rotor 2 more safely and smoothly. Compared with traditional wrenches, the driving member 20 can achieve safe and fast electric drive operation without the phenomenon of difficulty in applying force and slow operation speed.

[0037] The two actuators 30 are indicated by 30(A) and 30(B) in FIG3 . The two actuators 30 are spaced apart on the base 10 , and the actuator 30(A) is used to cooperate with the connecting member 3 , and the actuator 30(B) is used to cooperate with the top support member 4 . The driving member 20 is transmission-connected between the two actuators 30 , and the driving member 20 can drive the two actuators to rotate at the same time. Of course, in actual use, only one of the connecting member 3 and the top support member 4 will appear in the disassembly and assembly of the exciter rotor 2 , that is, only one of the connecting member 3 and the top support member 4 will be installed on the exciter rotor 2 , and correspondingly, only one of the two actuators 30 will contribute to the disassembly and assembly of the exciter rotor 2 , that is, when one of the actuators 30 cooperates with the connecting member 3 or the top support member 4 , the other group of actuators 30 is in an idling state.

[0038] A first mounting hole 14 and a second mounting hole 15 are provided on the base 10. The first mounting hole 14 and the second mounting hole 15 both include a hole located in the first plate portion 11 and a hole located in the second plate portion 12. The first mounting hole 14 and the second mounting hole 15 are arranged at intervals. The first mounting hole 14 and the second mounting hole 15 are respectively used to accommodate two actuators 30.

[0039] The wrench of the present application can integrate two wrenches for disassembly and assembly by setting two actuators 30, and only one wrench can realize the disassembly and assembly of the exciter rotor 2 without changing tools. The two actuators 30 share one driving member 20 and controller, which is highly practical, effectively reduces the manufacturing cost and improves the disassembly and assembly efficiency of the exciter rotor 2.

[0040] It can be understood that the structures of the two actuators 30 of the present application and the effects they produce on the connecting member 3 and the supporting member 4 are basically the same, and the two only differ in size. Therefore, one group of actuators 30 will be described below, and the other group of actuators 30 will not be described in detail.

[0041] The two ends of the actuator 30 are rotatably connected to the first plate portion 11 and the second plate portion 12 respectively. Specifically, the first end of the actuator 30 is connected to the first plate portion 11 through a ball bearing, and the second end of the actuator 30 is also connected to the second plate portion 12 through a ball bearing. In other embodiments, the actuator 30 can also be rotatably connected to the first plate portion 11 and the second plate portion 12 through other bearings or other components.

[0042] As shown in FIG4 and FIG5 , the actuator 30 includes a main body 31 and a ring tooth portion 32. The main body 31 is provided with a matching hole 311, which is used to match with the connecting member 3 or the supporting member 4, and the ring tooth portion 32 is fixedly connected to the outer circumferential surface of the main body 31, and the ring tooth portion 32 is in transmission connection with the driving member 20.

[0043] Furthermore, each of the two actuators 30 is provided with a matching hole 311, and the sizes of the two matching holes are different, and the two matching holes match the shapes of the ends of the connecting member and the top support member, respectively. Specifically, the ends of the connecting member 3 and the top support member 4 are in an outer hexagonal shape, and correspondingly, the matching hole 311 is in an inner hexagonal shape. After the wrench of the exciter rotor 2 is installed, the inner hexagon of the matching hole 311 matches the outer hexagon of the connecting member 3 or the top support member 4, so when the actuator 30 rotates, it can drive the connecting member 3 and the top support member 4 to rotate synchronously.

[0044] Furthermore, the transmission part 22 may be a gear, and the teeth on the outer periphery of the annular gear part 32 may mesh with the teeth of the transmission part 22 , so that the transmission part 22 may transmit the driving force of the driving part 21 to the actuator 30 .

[0045] Referring again to Fig. 1, the exciter rotor disassembly wrench 5 further comprises a locking member 40. The locking member is disposed on the base 10 and can cooperate with the exciter rotor. The locking member is used to detachably connect the base 10 and the exciter rotor 2.

[0046] In the embodiment disclosed in the present application, the locking member 40 includes a mounting portion 41, an extension portion 42 and a locking portion 43. The mounting portion 41 is sleeved on the connecting portion 13 and protrudes out of the outside of the first plate portion 11. The mounting portion 41 is parallel to the first plate portion 11. The extension portion 42 extends from the end of the mounting portion 41 away from the first plate portion 11 to the end away from the driving member 20, and the extension portion 42 is perpendicular to the mounting portion 41. A through hole is provided through the mounting portion 41 and the extension portion 42, and a locking portion 43 is provided in the through hole. Specifically, the locking portion 43 can be a bolt, and a bolt hole is provided on the generator rotor 1. The entire wrench can be installed on the exciter rotor 2 by rotating the locking portion 43. Of course, the wrench can be removed from the exciter rotor 2 by rotating the locking portion 43 in the opposite direction.

[0047] The exciter rotor disassembly wrench 5 also includes a fixed arm 50. The fixed arm 50 is arranged on the base 10, and the fixed arm 50 protrudes out of the base 10. Two fixed arms 50 are arranged, and the two fixed arms 50 can respectively cooperate with the two pin holes c and d on the exciter rotor. When the actuator 30 rotates, the fixed arm 50 can provide a reaction torque to the base 10 so that the base 10 remains stationary relative to the exciter rotor 2. For example, when the driving member 20 drives the actuator 30 to rotate in the forward direction at 100N / m, the entire wrench will withstand 100N in the reverse direction. By using the two fixed arms 50 as reaction force arms, the first plate portion 11 and the second plate portion 12 can be prevented from rotating with the rotation of the actuator 30.

[0048] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0049] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0050] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.
