The generator mainly includes a rotor and a stator, and the rotor is rotatably installed in the inner cavity of the stator.

Generally, the rotor has a diameter of about 2 meters, an axis length of about 15.38 meters, and a weight of about 244 tons. The rotor is long and heavy. After the rotor is pulled out of the stator, the staff can enter the inner cavity of the stator to perform a series of inspections and test operations. This is time-consuming and labor-intensive.
[0003] In the related art, in order to solve this problem, a mobile device such as a maintenance robot is generally used to enter between the stator and the rotor for maintenance.

[0048] For ease of understanding, the structure of the stator is explained here: the stator mainly includes an iron core, a coil winding and a plurality of slot wedges. The plurality of slot wedges are arranged circumferentially along the inner wall of the iron core. The slot wedges are fixedly connected to the iron core to fix the coil winding on the inner wall of the iron core. A groove is formed by a gap between two adjacent slot wedges. The groove is arranged along the axial direction of the stator. The bottom of the groove is the inner wall of the iron core. The bottom of the groove is magnetic. The slot wedges are mostly made of insulating materials, and the slot wedges are not magnetic. After the moving device enters between the rotor and the stator, the moving device is generally adsorbed in the groove of the stator and moves along the groove. The process of the moving device entering the groove of the stator from the end of the stator is the slot entry process. The guiding device of the present application mainly guides the moving device along the axial direction of the stator during the slot entry process to improve the slot entry accuracy of the moving device, so that the moving device enters the groove and moves along the groove to accurately reach the working position.
[0049] Referring to Figures 1-3, the X direction shown in Figures 1-3 refers to the first preset direction. The guiding device 1 provided in one embodiment of the present application can be used to guide the mobile device 4 between the first connecting member 3 and the second connecting member 2, and the second connecting member 2 is sleeved outside the first connecting member 3. Specifically, the guiding device 1 includes a plurality of guiding mechanisms 11 and connecting mechanisms 12, and the guiding mechanism 11 is extended along the first preset direction, and the guiding mechanism 11 is used for sliding connection of the mobile device 4. The connecting mechanism 12 is connected to two adjacent guiding mechanisms 11, and the connecting mechanism 12 can support and fix the guiding mechanism 11, so that the position of the guiding mechanism 11 is stable, not easy to shake or deviate, and has good supporting rigidity.
[0050] In this embodiment, the guide device 1 can be installed between the first connecting member 3 and the second connecting member 2, and a conveying channel extending along the first preset direction can be formed between two adjacent guide mechanisms 11, so as to facilitate conveying by the mobile device 4. The connecting mechanism 12 is connected between two adjacent guide mechanisms 11, and can support and fix the guide mechanism, reduce the displacement of the guide mechanism 11, and enable the mobile device 4 to be smoothly conveyed to between the first connecting member 3 and the second connecting member 2 through the guide mechanism 11, avoiding the mobile device 4 from walking on the uneven structure at the end of the second connecting member 2, reducing the position deviation of the mobile device 4 during the conveying process, and improving the conveying accuracy of the mobile device 4. The guide device can be applied to the rotor and the stator, solving the problem of position deviation when the mobile device enters between the rotor and the stator.
[0051] In this embodiment, the waiting working position is located between the second connecting member 2 and the first connecting member 3, the output end of the guide mechanism 11 faces the waiting working position, and the end of the guide mechanism 11 can extend between the second connecting member 2 and the first connecting member 3, and can be set close to the inner wall of the second connecting member 2. After the mobile device 4 is output from the guide mechanism 11, it can be adsorbed on the inner wall of the second connecting member 2 and move toward the waiting working position, thereby reducing the position deviation of the mobile device 4 during the transportation process, so that the mobile device 4 can be smoothly transported to the waiting working position.
[0052] Among them, if there are multiple waiting working positions, by aligning the guide device 1 with different waiting working positions respectively, the maintenance robot can be transported to different waiting working positions respectively. The guide mechanism 11 has a first end and a second end that are relatively arranged, the first end of the guide mechanism 11 extends between the first connecting member 3 and the second connecting member 2, and the second end of the guide mechanism 11 is located outside the first connecting member 3 and the second connecting member 2, that is, the guide mechanism 11 can partially extend between the first connecting member 3 and the second connecting member 2, the moving device 4 can be moved from the second end of the guide mechanism 11 to the first end of the guide mechanism 11, and the first end of the guide mechanism 11 can be docked at the groove position of the second connecting member 2, reducing the distance between the moving device 4 and the groove of the second connecting member 2 when the guide mechanism 11 is output, and the groove entry process is smoother.
[0053] Referring to FIG. 3-4 , the Y direction shown in FIG. 3-4 refers to the second preset direction. In some embodiments, a plurality of guide mechanisms 11 are arranged at intervals along the second preset direction, and the second preset direction is arranged to intersect with the first preset direction, that is, the guide mechanism 11 can form one or more conveying channels along the second preset direction for the mobile device 4 to convey respectively. The first preset direction and the second preset direction are different directions, and the angle between the two can be an acute angle or a right angle.
[0054] In this embodiment, two adjacent guide mechanisms 11 can be respectively arranged on both sides of the mobile device 4, and the guide mechanisms 11 are slidably connected to the side of the mobile device 4, so that the height of the guide device 1 is much smaller than the width of the guide device 1. The guide device 1 is flat in design, which not only makes it easier for the guide mechanism 11 to enter the narrow air gap between the first connecting member 3 and the second connecting member 2, but also the connecting mechanism 12 is connected to each guide mechanism 11, and the connecting mechanism 12 has good supporting rigidity along the circumference of the second connecting member 2, so that the position of the guide mechanism 11 is stable and not easy to shake or shift.
[0055] Among them, two guide mechanisms 11 can be provided, and the two guide mechanisms 11 can be respectively provided on both sides of the mobile device 4. The mobile device 4 slides between the two guide mechanisms 11. The structure is simple, the required layout space is small, and the layout is convenient, so that the end of the guide mechanism 11 can be more easily extended between the second connecting member 2 and the first connecting member 3.
[0056] Referring to Figures 3-4, in some embodiments, a sliding member 41 may be provided on the side of the mobile device 4. The sliding member 41 may be but not limited to a slider or a roller. The guide mechanism 11 may be but not limited to a groove structure or a rod structure. The sliding member 41 is mounted on the rod and can slide smoothly along the rod. Of course, the guide mechanism 11 can also be designed as a guide rail 111 or other guiding structures to meet the guiding needs of the mobile device 4.
[0057] Referring to FIGS. 3-4 , in some embodiments, the guide mechanism 11 includes a guide rail 111 and a guide groove 112. The guide rail 111 is extended along a first preset direction, and the guide rail 111 is connected to the connection mechanism 12. The guide rail 111 has a first end and a second end that are oppositely arranged. The first end of the guide mechanism 11 is configured as the first end of the guide rail 111, and the first end of the guide rail 111 is used to extend between the second connection member 2 and the first connection member 3. The second end of the guide mechanism 11 is configured as the second end of the guide rail 111, and the second end of the guide rail 111 is located outside the second connection member 2.
[0058] The guide groove 112 is provided on the side wall of the guide rail 111, and is used for sliding connection of the mobile device 4. For example, the guide groove 112 allows the sliding member 41 on the side of the mobile device 4 to extend into the sliding member 41 and the sliding member 41 slides relative to the guide groove 112. The guide groove 112 is extended along the first preset direction, and the notches of the guide grooves 112 of two adjacent guide mechanisms 11 are arranged relatively, so that the guide grooves 112 are arranged on both sides of the mobile device 4, and the side of the mobile device 4 is slidably guided, so that the height of the guide device 1 is much smaller than the width of the guide device 1, and the guide device 1 is flat in design, which is not only easier to enter the narrow air gap between the first connecting member 3 and the second connecting member 2, but also has good lateral rigidity.
[0059] In this embodiment, the guide groove 112 passes through the two ends of the guide rail 111 so that the moving device 4 can enter the guide groove 112 from one end of the guide rail 111 and slide along the guide groove 112 to be output from the other end of the guide rail 111. Of course, the moving device 4 can also enter and exit at the same end of the guide rail 111.
[0060] Referring to Figures 6-7, the Z direction shown in Figure 6 refers to the third preset direction. In some embodiments, the guide mechanism 11 further includes a first support wheel 113, which is rotatably connected to the guide rail 111. The first support wheel 113 is arranged on one side of the guide rail 111 along the third preset direction, and the third preset direction is arranged to intersect with the first preset direction and the second preset direction in pairs, that is, the first preset direction, the second preset direction and the third preset direction are three different directions, and optionally, the first preset direction, the second preset direction and the third preset direction can be perpendicular to each other. Specifically, the first support wheel 113 can be arranged close to the first connecting member 3, and the first support wheel 113 supports the guide rail 111 from the first connecting member 3, which can reduce the contact between the guide rail 111 and the first connecting member 3, and reduce the wear between the guide rail 111 and the first connecting member 3, and when the guide device 1 needs to change its position along the circumferential direction of the second connecting member 2, the first support wheel 113 can roll along the outer wall of the first connecting member 3, reduce the friction resistance, and make the position change smoother and more convenient.
[0061] In this embodiment, the first support wheel 113 is away from the first end of the guide rail 111, for example, the first support wheel 113 can be arranged in the middle position of the guide rail 111. Each guide mechanism 11 can be provided with at least one first support wheel 113, and the first support wheels 113 of multiple guide mechanisms 11 can be arranged on the same radial section of the second connecting member 2. Alternatively, the first support wheels 113 of multiple guide mechanisms 11 can also be arranged on different radial sections of the second connecting member 2. The rotation axis of the first support wheel 113 extends at least along the first preset direction, that is, the first support wheel 113 can at least roll along the circumferential direction of the second connecting member 2. Of course, the first support wheel 113 can also be designed as a universal wheel, and the rotation movement is more flexible.
[0062] Referring to FIGS. 4-5 , in some embodiments, the guide mechanism 11 further includes a second support wheel 114. The first support wheel 113 and the second support wheel 114 may be provided at the same time, or only one of the two may be provided. The second support wheel 114 is rotatably connected to the guide rail 111. The second support wheel 114 is provided on the other side of the guide rail 111 along the third preset direction. The second support wheel 114 is provided close to the second connecting member 2. The second support wheel 114 is close to the first end of the guide rail 111. The second support wheel 114 can support the first end of the guide rail 111, reduce the force deformation of the first end of the guide rail 111, and make the moving device 4 move more smoothly when entering and exiting the guide groove 112 from the first end of the guide rail 111, and reduce the deformation of the guide rail 111 and the position interference of the moving device 4. The second support wheel 114 separates the guide rail 111 from the second connecting member 2, which can reduce the contact between the guide rail 111 and the second connecting member 2, and reduce the wear between the guide rail 111 and the second connecting member 2. Moreover, when the guide device 1 needs to change its position along the circumferential direction of the second connecting member 2, the second support wheel 114 can roll along the inner wall of the second connecting member 2 to reduce friction resistance, making the position change smoother and more convenient. In addition, the first support wheel 113 and the second support wheel 114 are respectively arranged at the top and bottom of the guide rail 111 for support, which can improve the vertical rigidity of the guide mechanism 11.
[0063] In this embodiment, each guide mechanism 11 may be provided with at least one second support wheel 114, and the second support wheels 114 of the plurality of guide mechanisms 11 may be arranged on the same radial cross section of the second connecting member 2. Alternatively, the second support wheels 114 of the plurality of guide mechanisms 11 may also be arranged on different radial cross sections of the second connecting member 2. The rotation axis of the second support wheel 114 extends at least along the first preset direction, that is, the second support wheel 114 can at least roll along the circumferential direction of the second connecting member 2. Of course, the second support wheel 114 may also be designed as a universal wheel, and the rotation movement is more flexible.
[0064] When assembling the guide device 1, the guide mechanism 11 can be connected to the connecting mechanism 12 first, and then the first end of the guide mechanism 11 can be extended to the air gap between the second connecting member 2 and the first connecting member 3, and then the second end of the guide mechanism 11 can be fixed outside the air gap between the second connecting member 2 and the first connecting member 3 through the connecting mechanism 12. For example, the connecting mechanism 12 can be installed on the rotating shaft of the first connecting member 3 to support and fix the guide mechanism 11. After assembly, the first end of the guide mechanism 11 extends into the air gap between the second connecting member 2 and the first connecting member 3, and the connecting mechanism 12 can be located outside the air gap between the second connecting member 2 and the first connecting member 3. The first support wheel 113 of the guide mechanism 11 is supported between the guide rail 111 and the first connecting member 3, and the second support wheel 114 is supported between the guide rail 111 and the second connecting member 2, so that the guide device 1 has good vertical rigidity and lateral rigidity, thereby improving the guiding accuracy.
[0065] Referring to FIG. 6 , in some embodiments, the guide mechanism 11 further includes an anti-scratch pad 116, which is disposed at the bottom of the guide mechanism 11 to reduce the friction between the guide mechanism 11 and the outer wall of the first connecting member 3. When a guard ring 31 is disposed at the end of the first connecting member 3, the anti-scratch pad 116 can be disposed at a position of the guide rail 111 corresponding to the guard ring 31 to reduce the wear on the surface of the guard ring 31. The anti-scratch pad 116 can be a long sheet structure, and the anti-scratch pad 116 can be laid at the bottom of the guide rail 111. Alternatively, the anti-scratch pad 116 can also be a block structure, and a plurality of anti-scratch pads 116 can be disposed along the length direction of the guide rail 111 to protect the bottom of the guide rail 111 at multiple points. The material of the anti-scratch pad 116 is a non-metallic material, for example, the material of the anti-scratch pad 116 can be selected to be polytetrafluoroethylene.
[0066] Referring to FIG. 4 and FIG. 8 , in some embodiments, the guide rail 111 includes a bottom plate 1111, a top plate 1112, and a connecting plate 1113, the bottom plate 1111 is connected to the connecting mechanism 12, the sliding member 41 is located between the bottom plate 1111 and the top plate 1112, so that the bottom plate 1111 can be supported on the bottom of the sliding member 41, the top plate 1112 can be blocked on the top of the sliding member 41, and the height distance between the bottom plate 1111 and the top plate 1112 is equal to or slightly greater than the height of the sliding member 41. The connecting plate 1113 is connected between the bottom plate 1111 and the top plate 1112, that is, the top plate 1112, the connecting plate 1113, and the bottom plate 1111 are connected in sequence to surround and form the guide groove 112. The connecting plate 1113 is arranged along the third preset direction so that the connecting plate 1113 can be blocked on the side of the sliding member 41. The bottom plate 1111, the top plate 1112 and the connecting plate 1113 can doubly limit the sliding member 41 along the second preset direction and the third preset direction, so that the sliding member 41 can slide smoothly in the guide groove 112, reducing the position deviation of the moving device 4 along the second preset direction and the third preset direction, and the groove insertion accuracy is high.
[0067] In this embodiment, the width of the bottom plate 1111 is greater than the width of the top plate 1112, and the connecting plate 1113 can be connected to the middle position of the bottom plate 1111, so that the cross section of the guide rail 111 can be an inverted T-shaped structure, the support area of the bottom plate 1111 is large, and the cross-sectional area of the guide rail 111 is small and light. The height of the connecting plate 1113 can be less than the width of the bottom plate 1111, so that the guide rail 111 is flat as a whole, the lateral bending resistance of the guide mechanism 11 is improved, and the lateral positioning accuracy of the mobile device 4 is enhanced. The cross-sectional size of the guide groove 112 is equal to or slightly larger than the size of the sliding member 41 of the mobile device 4. For example, the width of the guide groove 112 can be 20 mm and the depth can be 14 mm. The bottom plate 1111, the top plate 1112 and the connecting plate 1113 are integrally formed, which is convenient for processing and enables the connection position of the three to withstand greater stress. The material of the guide rail 111 may be, but is not limited to, a light metal. For example, the material of the guide rail 111 may be a light aluminum alloy. The guide rail 111 may also be hard-oxidized to improve its wear resistance.
[0068] In some embodiments, generally, the inner wall of the second connecting member 2 is provided with a plurality of grooves 21, and the plurality of grooves 21 are arranged along the circumference of the second connecting member 2, and the angle between the bottom plates 1111 of two adjacent guide mechanisms 11 is equal to the angle between adjacent grooves of the second connecting member 2, so that the force direction of the supporting force of the bottom plate 1111 on the mobile device 4 can be toward the direction of the corresponding groove, thereby reducing the position deviation of the mobile device 4 along the circumference of the second connecting member 2 in the process from the guide mechanism 11 to the groove of the second connecting member 2, thereby improving the groove entry accuracy of the mobile device 4.
[0069] Of course, the angle between the top plates 1112 of two adjacent guide mechanisms 11 and the angle between adjacent grooves of the second connecting member 2 may also be equal, so that when the mobile device 4 is partially adsorbed on the groove of the second connecting member 2, the force direction of the top plate 1112 on the mobile device 4 can be along the third preset direction, thereby reducing the circumferential force of the top plate 1112 on the mobile device 4, thereby reducing the position deviation of the mobile device 4 along the circumference of the second connecting member 2 during the groove entering process.
[0070] Referring to FIG. 6 , in some embodiments, a weight-reducing structure 13 is provided on both the guide mechanism 11 and the connection mechanism 12. The weight-reducing structure 13 can be configured as a hole or a groove, which can reduce the weight of the guide mechanism 11 and the connection mechanism 12, thereby reducing the overall weight of the guide device 1 and reducing the extrusion of the first connection member 3 or the second connection member 2 by the guide device 1 during maintenance. For example, a plurality of weight-reducing holes can be provided on the guide rail 111 of the guide mechanism 11, and the weight-reducing holes can be provided along the length direction of the guide rail 111. A plurality of weight-reducing grooves can be provided on the connection frame of the connection mechanism 12, which can greatly reduce the weight of the connection frame. An oval hole can be provided on the connection plate 1113, which can not only reduce weight, but also facilitate the installation of guide ropes of various mobile devices 4.
[0071] Referring to Figure 5, in this embodiment, a recessed portion 1115 is provided on the side wall of the top plate 1112 facing the mobile device 4, and the recessed portion 1115 is provided at the second end position of the guide mechanism 11. The recessed portion 1115 can not only reduce the weight of the guide rail 111, but also be used to avoid the mobile device 4 and reduce the positional interference between the top plate 1112 and the mobile device 4.
[0072] Referring to FIG. 8 , in some embodiments, the first end of the guide rail 111 is provided with an outwardly expanded opening 1114, the size of the outwardly expanded opening 1114 gradually increases from the second end to the first end of the guide rail 111, and the outwardly expanded opening 1114 is used to guide the moving device 4 to enter and exit. Specifically, at the first end position of the guide mechanism 11, the width of the top plate 1112 and the bottom plate 1111 gradually decreases from the second end to the first end of the guide mechanism 11, and / or the thickness of the top plate 1112 and the bottom plate 1111 gradually decreases from the second end to the first end of the guide mechanism 11, so as to form the outwardly expanded opening 1114 structure, so that the cross-sectional area of the guide groove 112 gradually increases from the second end to the first end of the guide mechanism 11, so that the sliding member 41 can enter or move out of the guide groove 112 more easily, and the redundancy of the moving device 4 returning to the guide mechanism 11 is improved.
[0073] Referring to FIGS. 6-8 , in some embodiments, the guide mechanism 11 further includes a guide block 115, which has a connecting end 1151 and a guiding end 1152 arranged opposite to each other, and the connecting end 1151 is detachably connected to the first end of the guide rail 111, so as to facilitate installation and removal. The guide block 115 has a guide surface 1153, and the guide surface 1153 is arranged corresponding to the position of the guide groove 112, and the distance between the two guide surfaces 1153 of two adjacent guide blocks 115 gradually increases from the connecting end 1151 to the guiding end 1152, that is, the side wall of the guide block 115 facing the mobile device 4 gradually moves away from the mobile device 4 from the connecting end 1151 to the guiding end 1152, so as to form an outer expansion port, and the outer expansion port can allow the mobile device 4 to smoothly enter and exit the guide groove 112.
[0074] The guide block 115 and the guide rail 111 are designed as a separate structure, and the width of the guide block 115 can be designed to be larger, so that the outer expansion opening can be designed to be larger, which increases the guiding range of the mobile device 4 while reducing the size requirement for the width of the guide rail 111. The outer expansion opening of the guide block 115 can be docked with the outer expansion opening 1114 structure at the first end of the guide rail 111, that is, the width of the large opening end of the outer expansion opening 1114 structure at the first end of the guide rail 111 is equal to the width of the small opening end of the outer expansion opening of the guide block 115, so that the mobile device 4 can enter and exit the guide groove 112 more smoothly.
[0075] In this embodiment, the connection between the connection end 1151 and the first end of the guide rail 111 can be, but is not limited to, a bolt connection or a clamping connection. The first end of the guide rail 111 can be provided with a plurality of connection positions along its width direction, and the guide block 115 can be connected to different connection positions respectively, so that the guide block 115 can be provided at different positions along the width direction of the guide rail 111 to form an outward expansion structure of different widths, which can be adjusted according to the in-and-out guiding needs of the mobile device 4.
[0076] Referring to Figures 5-6, in some embodiments, a plurality of connecting mechanisms 12 are provided, and the plurality of connecting mechanisms 12 are spaced apart along a first preset direction. The plurality of connecting mechanisms 12 can support different positions of the guide mechanism 11, so that the guide mechanism 11 is more stable, and deformation is reduced, thereby improving the overall lateral rigidity of the guide device 1, and thus improving the guiding accuracy. Moreover, the connecting mechanism 12 is away from the first end of the guide mechanism 11, so that the first end of the guide mechanism 11 forms a suspended free end with a smaller cross-sectional area, which is more convenient for extending into the narrow air gap between the second connecting member 2 and the first connecting member 3, thereby reducing the position interference of the connecting mechanism 12 with the second connecting member 2 or the first connecting member 3.
[0077] In this embodiment, the connection mechanism 12 can be configured as a connection frame, which is a hollow frame structure that can provide support and reduce weight. Two guide mechanisms 11 can be arranged in parallel, and the setting direction of the guide mechanism 11 is perpendicular to the setting direction of the connection mechanism 12. The connection mechanism 12 can both support the guide mechanism 11, and the connection is convenient.
[0078] In some embodiments, the guide mechanism 11 and the connection mechanism 12 are detachably connected, that is, the guide mechanism 11 and the connection mechanism 12 are assembled in a modular manner, which is convenient for transportation and assembly at the maintenance site. During installation, the guide device 1 can be partially inserted between the second connection member 2 and the first connection member 3 before being fixed, which reduces the installation risk and is more suitable for maintenance conditions where the installation position of the second connection member 2 and the first connection member 3 is narrow.
[0079] In this embodiment, the connection between the connecting mechanism 12 and the guiding mechanism 11 may be, but is not limited to, bolt connection or clamping, so that the connecting mechanism 12 and the guiding mechanism 11 can be quickly assembled at the construction site and transported after disassembly.
[0080] 2-3, the generator maintenance equipment provided by at least one embodiment of the present application includes a first connecting member 3, a second connecting member 2, a moving device 4 and the above-mentioned guide device 1, the second connecting member 2 is sleeved on the outside of the first connecting member 3, the guide device 1 is arranged between the first connecting member 3 and the second connecting member 2, and the moving device 4 is slidably connected to the guide device 1.
[0081] In this embodiment, the first connecting member 3 can be configured as a rotor, the second connecting member 2 can be configured as a stator, and the moving device 4 can be configured as a maintenance robot, and the maintenance robot is slidably connected to the guide mechanism 11. The waiting position is configured as the waiting position for maintenance, and the guide mechanism 11 is installed between the rotor and the stator. The maintenance robot can be slidably transported along the guide mechanism 11, and can be transported from the outside of the stator toward the waiting position to the inner wall of the stator, thereby avoiding the maintenance robot from walking on the uneven structure of the stator end. Moreover, the end of the guide mechanism 11 extends between the rotor and the stator, toward the waiting position for maintenance, and close to the inner wall of the stator. After the maintenance robot is output from the guide mechanism 11, it can be adsorbed on the inner wall of the stator and move toward the waiting position for maintenance, thereby reducing the positional deviation of the maintenance robot during the transportation process and improving the transportation accuracy of the maintenance robot, so that the maintenance robot can be more smoothly transported to the waiting position for maintenance.
[0082] In some embodiments, a plurality of guide devices 1 are provided, and the plurality of guide devices 1 are respectively provided at the two end positions of the first connecting member 3. For example, two guide devices 1 may be provided, and the two guide devices 1 may be relatively provided at the two end positions of the first connecting member 3, that is, the guide devices 1 may be respectively provided at the steam end and the excitation end of the generator, so that both ends of the first connecting member 3 can be provided for the maintenance robot to perform slot entering operations. The maintenance robot can enter the slot at one end and then change slots at the other end, which is also convenient for reducing the movement distance of the maintenance robot during the slot changing process.
