[0003] In some existing technologies, the installation of the skateboard requires manual pulling. When inserting the skateboard, the friction and weight of the skateboard make installation difficult, and there is a risk that the skateboard will collide with the generator rotor, which greatly wastes the time for removing the rotor. At the same time, a lot of manpower is required to pull the skateboard, which reduces work efficiency and safety. Utility Model Content

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0029] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0030] Please see Figures 1 to 3The first embodiment of this utility model provides a sliding plate traction device for a generator rotor, comprising: a fixed frame 1, a traction rope 2, a winding traction mechanism 3, and a connecting assembly 4. The fixed frame 1 includes: a support member 11 and a limiting member 12 for fixing to a bearing housing flange 9. The limiting member 12 is fixedly installed on the support member 11, and a limiting groove 13 for engaging with the bearing housing flange 9 is provided between the limiting member 12 and the support member 11. The winding traction mechanism 3 is installed on the support member 11, one end of the traction rope 2 is fixed to the winding traction mechanism 3, and the other end of the traction rope 2 is installed on the sliding plate 5 through the connecting assembly 4.

[0031] This application provides a limiting groove 13 between the limiting member 12 and the support member 11 for locking onto the bearing housing flange 9. The winding traction mechanism 3 is mounted on the support member 11, one end of the traction rope 2 is fixed to the winding traction mechanism 3, and the other end of the traction rope 2 is mounted on the slide plate 5 through the connecting assembly 4. The operator aligns the limiting groove 13 with the bearing housing flange 9, and then secures the entire fixing frame 1 to the bearing housing flange 9 through the limiting groove 13, keeping the fixing frame 1 and the bearing housing flange 9 relatively stationary. The winding traction mechanism 3 is then aligned with the stator. The traction rope 2, one end of which is connected to the winding traction mechanism 3, is then installed on the slide plate 5 through the connecting assembly 4. The operator then activates the winding traction mechanism 3, causing it to tighten the traction rope 2. Under the action of the winding traction mechanism 3, the traction rope 2 generates tension, pulling the slide plate 5 to the appropriate position. The entire process reduces personnel involvement, improves work efficiency and safety, and allows the slide plate 5 to be pulled to the appropriate position more smoothly, reducing the risk of the slide plate 5 colliding with the generator rotor, thereby improving safety and protecting the generator rotor, and saving maintenance costs.

[0032] The winding traction mechanism 3 can be a winding machine or an electric traction machine, driven by electricity, so that the winding traction mechanism 3 can release or tighten the traction rope 2, so that the other end of the traction rope 2 generates tension, which acts on the slide plate 5, thereby saving manufacturing costs and making the operation more stable.

[0033] Among them, the support member 11 provides an installation position for the winding traction mechanism 3. After the limiting member 12 is fixed to the bearing housing flange 9, the winding traction mechanism 3 can be parallel to the rotor axis. When the traction rope 2 pulls the slide plate 5, it can prevent the tip from lifting, further reducing the risk of the slide plate 5 colliding with the generator rotor and improving safety.

[0034] The limiting groove 13 makes it easier for operators to fix the entire fixing frame 1 onto the bearing box flange 9, which further improves the installation efficiency, thereby improving the installation efficiency of the sliding plate 5 and saving working time.

[0035] The end of the traction rope 2 away from the winding traction mechanism 3 can be directly tied to the skateboard 5. The connecting component 4 is used to restrict the traction rope 2 and the skateboard 5, which further saves manufacturing costs and makes it safer to pull the skateboard 5.

[0036] Please see Figures 1 to 3 In some embodiments, the mounting bracket 1 further includes a reinforcing member 15 installed between the support member 11 and the limiting member 12, and a handle 16 is mounted on the reinforcing member 15.

[0037] This application also includes a reinforcing member 15 installed between the support member 11 and the limiting member 12, with a handle 16 mounted on the reinforcing member 15. The reinforcing member 15 increases the connection strength between the support member 11 and the limiting member 12, making the winding traction mechanism 3 more stable when pulling the slide plate 5 via the traction rope 2, further improving safety and service life. The handle 16 facilitates the operator's movement of the entire device; the entire device can be lifted using the handle 16 and quickly moved to the designated location for installation, further improving work efficiency. The handle 16 also increases the overall strength of the fixing member 1, further extending its service life.

[0038] Please see Figures 1 to 3 In some embodiments, the mounting bracket 1 further includes a guide assembly 17 mounted on the support 11 to guide the traction rope 2 to the winding traction mechanism 3.

[0039] This application utilizes a guide assembly 17 installed on the support member 11 to guide the traction rope 2 onto the winding traction mechanism 3, preventing the traction rope 2 from becoming knotted or tangled, thus further improving safety. The guide assembly 17 can be a limiting ring or a groove on the support member 11. Through the cooperation of the limiting ring and the groove, the traction rope 2 can be stably guided onto the winding traction mechanism 3, preventing the traction rope 2 from detaching or becoming tangled, further improving the efficiency and safety of the moving slide plate 5.

[0040] The guide component 17 can also be a roller. By installing a grooved roller at the front end of the winding traction mechanism 3, and then placing the traction rope 2 into the groove of the roller, the friction between the traction rope 2 and the support member 11 when tightening can be reduced, thus extending the service life. The grooved roller can improve the smoothness of tightening the traction rope 2, further improving work efficiency and safety, and preventing the traction rope 2 from getting tangled or twisted during the pulling of the slide plate 5.

[0041] Please see Figures 1 to 5In some embodiments, the limiting member 12 includes a first limiting block 121 and a second limiting block 122. The first limiting block 121 is mounted on the support member 11 and has a first mounting hole 14. The second limiting block 122 is detachably mounted on the first limiting block 121 and has a second mounting hole 123. Protective gaskets 6 are provided between the support member 11, the first limiting block 121 and the second limiting block 122 and the bearing housing flange 9.

[0042] This application utilizes a limiting component 12, comprising a first limiting block 121 and a second limiting block 122. The first limiting block 121 is mounted on the support member 11 and has a first mounting hole 14. Through the limiting groove 13 formed between the first limiting block 121 and the support member 11, the entire device can be horizontally mounted on the bearing housing flange 9, allowing the winding traction mechanism 3 to more stably pull the slide plate 5 to a suitable position. The first mounting hole 14 on the first limiting block 121 allows the operator to use bolts to pass through it and install the device on the bearing housing flange 9 via threaded connections. The bolts further secure the fixing frame 1 to the bearing housing flange 9, further improving safety and stability.

[0043] This application allows for the detachable installation of a second limiting block 122 onto a first limiting block 121. The second limiting block 122 has a second mounting hole 123. Through the limiting groove 13 formed by the second limiting block 122, the first limiting block 121, and the support member 11, the fixing frame 1 can be vertically installed on the bearing housing flange 9. This allows for the selection of different installation methods based on actual site conditions, expanding the applicable range and further improving the stability of the winding traction mechanism 3 moving the sliding plate 5 via the traction rope 2. Changing installation methods is also more convenient and labor-saving, improving work efficiency. Similarly, the second mounting hole 123 on the second limiting block 122 allows for bolt installation onto the bearing housing flange 9, further enhancing the connection strength and thus improving safety and stability.

[0044] This application provides protective gaskets 6 between the support member 11, the first limiting block 121, the second limiting block 122, and the bearing housing flange 9. The protective gaskets 6 can prevent wear on the bearing housing flange 9 when the fixing bracket 1 is installed on the bearing housing flange 9, thus providing a certain degree of protection for the bearing housing flange 9 and reducing maintenance pressure. In addition, they can increase the friction between the fixing bracket 1 and the bearing housing flange 9, preventing shaking when the sliding plate 5 is moved, and further improving stability.

[0045] Please see Figures 1 to 3In some embodiments, the winding traction mechanism 3 includes: a frame 31, a winding shaft 32, a motor 33, and an operating handle 34. The frame 31 is detachably mounted on the support member 11, the winding shaft 32 is rotatably connected to the frame 31, one end of the traction rope 2 is mounted on the winding shaft 32, the motor 33 is mounted on the frame 31, the output shaft of the motor 33 is connected to the winding shaft 32, and the operating handle 34 is electrically connected to the motor 33.

[0046] This application utilizes a frame 31 that is detachably mounted on a support 11. A take-up shaft 32 is rotatably connected to the frame 31. One end of the traction rope 2 is mounted on the take-up shaft 32. A motor 33 is mounted on the frame 31, with its output shaft connected to the take-up shaft 32. An operating handle 34 is electrically connected to the motor 33. After the other end of the traction rope 2 is stably connected to the slide plate 5 via a connecting assembly 4, the fixing frame 1 is also stably mounted on the bearing housing flange 9. The operator then powers on the motor 33 and controls its forward and reverse rotation via the operating handle 34. This causes the output shaft of the motor 33 to drive the take-up shaft 32 to tighten or release the traction rope 2. The operator can control the rotation of the motor 33 remotely via the operating handle 34, thereby increasing the safety distance and providing sufficient reaction time and evacuation distance in emergencies, further improving safety. Furthermore, the operator can more comfortably control the rotation of the motor 33 via the operating handle 34, improving work comfort and reducing labor intensity.

[0047] Please see Figures 1 to 3 In some embodiments, the connecting component 4 includes a first connector 41 and a pull rope 42, the first connector 41 being mounted on the other end of the traction rope 2, a portion of the pull rope 42 being constrained on the first connector 41, and the end of the pull rope 42 being mounted on the slide plate 5.

[0048] This application uses a first connector 41 to install the other end of the traction rope 2. A portion of the pull rope 42 is constrained on the first connector 41, and the end of the pull rope 42 is mounted on the slide plate 5. The first connector 41 can be a ring or a hook, allowing a portion of the pull rope 42 to slide and be confined within it. The pull rope 42 within the first connector 41 can slide left and right. When the traction rope 2 pulls the pull rope 42 through the first connector 41, the sliding pull rope 42 automatically moves to a symmetrical position on the first connector 41, further preventing the pull rope 42 from tangling. This makes moving the slide plate 5 smoother, saves time on tidying the pull rope 42, and improves work efficiency.

[0049] The first connector 41 can also be fixedly connected to the pull rope 42. The first connector 41 makes the connection between the pull rope 42 and the traction rope 2 more stable, further improving safety.

[0050] The pull rope 42 is installed on the traction rope 2 through the first connector 41. After the pull rope 42 is worn out after repeated use, it can be replaced in time, saving maintenance costs and facilitating operation.

[0051] Please see Figures 1 to 3 In some embodiments, the connecting component 4 further includes a second connector 43 installed at both ends of the pull rope 42, with one end of the second connector 43 installed on the pull rope 42 and the other end of the second connector 43 installed on the slide plate 5.

[0052] This application also includes a second connector 43 installed at both ends of the pull rope 42 via the connector 4. One end of the second connector 43 is installed on the pull rope 42, and the other end of the second connector 43 is installed on the slide plate 5. The second connector 43 can be used to quickly install the pull rope 42 between the slide plate 5 and the first connector 41, improving work efficiency. The second connector 43 can reduce the friction between the pull rope 42 and the slide plate 5, thereby extending the service life of the pull rope 42, reducing wear and tear, and saving maintenance costs. The second connector 43 can further improve the connection strength between the pull rope 42 and the slide plate 5, further improving safety.

[0053] Please see Figures 1 to 3 In some embodiments, the second connector 43 is a hook, bolt, or strap.

[0054] This application utilizes a second connector 43, which can be a hook, bolt, or strap. The hook-shaped second connector 43 allows the operator to quickly attach it to the slide plate 5, facilitating operation and improving work efficiency.

[0055] The bolted second connector 43 can further improve the connection strength with the slide plate 5, prevent the second connector 43 from separating from the slide plate 5, and further improve safety and stability.

[0056] The second connector 43, which is in the form of a strap, can be used in narrower gaps between the stator and rotor, making it suitable for a wider range of applications.

[0057] Please see Figures 1 to 6 The present invention also provides a generator rotor core-piercing device, comprising: the aforementioned generator rotor sliding plate traction device, and a sliding plate 5 connected to the generator rotor sliding plate traction device, wherein the sliding plate 5 is provided with a connecting hole 7, and the connecting component 4 is connected to the sliding plate 5 through the connecting hole 7.

[0058] This application utilizes a connecting hole 7 on the slide plate 5, where a second connector 43 from the connecting assembly 4 connects to the slide plate 5. When the slide plate 5 has one connecting hole 7, the pull rope 42 can be quickly installed on the slide plate 5 using the second connector 43, thereby improving work efficiency. When multiple connecting holes 7 are symmetrically arranged on the slide plate 5, the pull rope 42 passes through the first connector 41 and is then quickly connected to the symmetrical connecting holes 7 using the second connectors 43 at both ends. When the traction rope 2 pulls the pull rope 42 taut through the first connector 41, the pull rope 42, which slides and is confined within the first connector 41, automatically forms symmetry, allowing the traction rope 2 to pull the pull rope 42 taut on the axis of symmetry after connection. This reduces the time spent adjusting the pull rope 42, improves work efficiency, makes the force on the pull rope 42 more even, reduces wear on the pull rope 42, and makes it more stable when pulling the slide plate 5, thereby improving stability and safety.

[0059] Please see Figures 1 to 6 In some embodiments, the side of the slide plate 5 closest to the rotor is provided as a smooth surface; or / and the other side of the slide plate 5 in contact with the stator is provided with a protective pad 8.

[0060] This application sets the side of the slide plate 5 closest to the rotor to be a smooth surface. After the slide plate 5 is installed in place, the smooth surface reduces friction, which facilitates the disassembly and assembly of the rotor in the stator and improves maintenance efficiency.

[0061] This application provides a protective pad 8 on the other side of the slide plate 5 that contacts the stator. When the slide plate 5 is moved to a suitable position using the slide plate traction device, the protective pad 8 moves with the slide plate 5 to protect the stator. This eliminates the need to lay a protective blanket in advance, further reducing labor intensity, facilitating operation, and improving work efficiency.

[0062] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
