Since the rolling mill motor will fail due to wear and tear, fatigue and other reasons during long-term operation, regular maintenance is essential.

[0046] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0047] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0048] Please refer to Figure 1 , Figure 1 The schematic diagram of the rolling mill motor turning detection device provided by the embodiments of the present application is shown in the figure.

[0049] As shown in Figure 1 , the rolling mill motor turning detection device adopts the form of combination of the first turning frame 100 and the second turning frame 200, the rotor shaft 01 in the rotor part of the rolling mill motor is supported by the first turning frame 100, and the rotor body 02 in the rotor part of the rolling mill motor is supported by the second turning frame 200. Further, in order to comprehensively turn and detect the rotor part, either the way of rotating the rotor part by the travelling crane and the lifting rope or the way of directly setting the structure for rotating the rotor part on the second turning frame 200 can be adopted, which is not limited here.

[0050] In addition to Figure 1 , the way of separately using the first turning frame 100 and the second turning frame 200 can also be adopted, and the use mode of the rolling mill motor turning detection device should not be limited by Figure 1 .

[0051] Please refer to Figure 2 and Figure 3 , among which, Figure 2 the schematic diagram of the first turning frame provided by the embodiments of the present application is shown in the figure, Figure 3 the schematic diagram of the first turning frame provided by the embodiments of the present application is shown in the figure.

[0052] In a first specific embodiment, the rolling mill motor turning gear detection device provided by the application implementation scheme mainly comprises a first turning gear frame 100, which is used to support the rotor shaft 01 of the rolling mill motor. The first turning gear frame 100 comprises a roller support column 1, a support beam 2 and a support roller 3. The support beam 2 is arranged on the roller support column 1, and a plurality of roller mounting positions 201 are arranged on the support beam 2. The roller mounting positions 201 are arranged at intervals along the length direction of the support beam 2. The support roller 3 is arranged at the roller mounting position 201, and the number of the support roller 3 is a pair, which is distributed along the direction perpendicular to the axial direction of the rotor shaft 01. By changing the mounting position of the support roller 3 on the support beam 2, the roller spacing is adjusted, which is suitable for the rotor shaft 01 with different shaft neck sizes.

[0053] In the traditional rolling mill motor maintenance process, due to the different shaft neck sizes of the rotor components, maintenance personnel often face the challenge of needing to customize specific supports and rollers for different sizes of shaft necks. This customization requirement not only increases the maintenance cost, but also prolongs the maintenance time, reduces the flexibility and efficiency of the maintenance work. In addition, frequent adjustment and customization may also cause errors in the maintenance process, affecting the maintenance quality and increasing the downtime of the production line.

[0054] To solve this problem, the technical scheme provides a rolling mill motor turning gear detection device. Through innovative design, the device realizes adaptive support for rolling mill motor rotor shafts 01 with different shaft neck sizes. Specifically, the device comprises a first turning gear frame 100, which is specially designed to support the rotor shaft 01 of the rolling mill motor. The first turning gear frame 100 is composed of a roller support column 1, a support beam 2 and a support roller 3. The support beam 2 is fixed on the roller support column 1, and a plurality of roller mounting positions 201 are arranged on the support beam 2. These mounting positions 201 are arranged at intervals along the length direction of the support beam 2, providing flexible adjustment space.

[0055] The most critical innovation lies in the design of the support roller 3. The support roller 3 is arranged in pairs and can be distributed along the direction perpendicular to the axial direction of the rotor shaft 01. By simply changing the mounting position of these support rollers 3 on the support beam 2, the roller spacing can be adjusted to adapt to rotor shafts 01 with different shaft neck sizes. This ingenious design solves the problem of frequent customization and adjustment caused by the difference in shaft neck size in the traditional maintenance method.

[0056] With this adjustable roller spacing design, maintenance personnel can quickly adjust the device to adapt to different sizes of the rotor shaft 01 without the need for complex customization or adjustment. This not only improves maintenance efficiency and reduces downtime, but also enhances the versatility of rotor support, allowing the same device to be used for multiple different models of rolling mill motors. In addition, this design helps improve maintenance quality by reducing errors caused by frequent adjustments, ensuring stable support for the rotor shaft 01 and ensuring continuous operation and safety of the production line.

[0057] In combination with the above structure and process description, it can be seen that the rolling mill motor turning detection device has at least the following beneficial effects: the rolling mill motor turning detection device realizes adaptive support for rolling mill motor rotor shafts 01 of different journal sizes through adjustable roller spacing, thereby solving the problem of frequent customization and adjustment caused by journal size differences in traditional maintenance methods, improving maintenance efficiency and the versatility of rotor support.

[0058] In some cases, for the rolling mill motor turning detection device using the first turning frame 100 alone, two sets of first turning frames 100 are used to support the rotor shafts 01 at both ends of the rotor part, and the rotor part is rotated by the crane and the lifting rope to achieve the purpose of turning detection and repair. Figure 1 Compared with the first turning frame 100, the second turning frame 200 is equivalent to being replaced by another set of first turning frames 100, and the support position of the first turning frame 100 is moved to the rotor shaft 01 for support. Figure 1 Since the two sets of first turning frames 100 do not have turning power, the method of rotating the rotor part by the crane and the lifting rope is adopted.

[0059] Please refer to Figures 4 to 6 , wherein Figure 4 is a schematic view of the support ring provided by the embodiment of the present application, Figure 5 is a schematic view of the support ring provided by the embodiment of the present application from another perspective, Figure 6 is a schematic view of the second turning frame provided by the embodiment of the present application.

[0060] In a specific embodiment, the rolling mill motor turning detection device further comprises:

[0061] The second turning frame 200 is used to support the rotor body 02 of the rolling mill motor, and the second turning frame 200 comprises:

[0062] The bearing seat 5;

[0063] The support ring 6 is provided on the bearing seat 5, and the support ring 6 is provided with a through hole 6101. The support ring 6 is connected with the rotor body 02, and the rotor shaft 01 passes through the through hole 6101.

[0064] The second disc frame 200 is different from the first disc frame 100 in that the first disc frame 100 supports the shaft extension end of the rotor part, i.e., the rotor shaft 01, while the second disc frame 200 supports the non-shaft extension end of the rotor part, i.e., the rotor body 02. The rotor shaft 01 is located at both ends of the rotor body 02, and the rotor body 02 is located in the middle of the rotor shaft 01.

[0065] Taking the rolling mill motor disc checking device using both the first disc frame 100 and the second disc frame 200 as an example.

[0066] In this embodiment, the rolling mill motor disc checking device achieves support for the rotor body 02 of the rolling mill motor by adding the second disc frame 200. The support ring 6 is fixed with the rotor body 02, and the support ring 6 can rotate on the bearing seat 5. The second disc frame 200 is an important component of the device, which is specially designed to support the rotor body 02, ensuring the stability and safety of the rotor body 02 during disc checking.

[0067] The second disc frame 200 includes a bearing seat 5 and a support ring 6. The bearing seat 5 serves as the installation basis for the support ring 6, providing a stable support platform for the support ring 6. The support ring 6 is a key component directly connected to the rotor body 02. The through hole 6101 is a special design inside the support ring 6, allowing the rotor shaft 01 to pass through it.

[0068] This design allows the support ring 6 to closely cooperate with the rotor body 02, and since the support ring 6 is integrated with the rotor body 02, they rotate synchronously. Such a structure not only provides stable support, but also ensures the rotational freedom of the rotor shaft 01 during detection, which is crucial for effective disc checking.

[0069] With the setting of the second disc frame 200, the rolling mill motor disc checking device can more comprehensively support the key components of the rolling mill motor, thereby improving the reliability and efficiency of the detection process. The design of this structure also reflects the adaptability of the device to different components, allowing it to meet diverse maintenance needs.

[0070] In some cases, the rolling mill motor disc checking device can also use the second disc frame 200 alone. In this case, the rolling mill motor needs to maintain the bearing support method of the original machine for the rotor shaft 01 that was originally supported by the first disc frame 100, thereby achieving the purpose of disc checking without extracting the rotor part on site. In addition, for the rotational movement of the rotor part during disc checking, either the method of rotating the rotor part by a travelling crane and a lifting rope or the method of directly setting a structure for rotating the rotor part on the second disc frame 200 can be used, without limitation.

[0071] In some embodiments, the bearing seat 5 comprises:

[0072] an adjustment bracket 51;

[0073] adjustment rollers 52, provided on the adjustment bracket 51, the number of adjustment rollers 52 is a pair, distributed along the direction perpendicular to the axial direction of the rotor shaft 01, the adjustment rollers 52 support the support ring 6;

[0074] a driving and transmission mechanism, provided on the adjustment bracket 51, the driving and transmission mechanism is connected with the adjustment rollers 52, and the driving and transmission mechanism is used to drive the adjustment rollers 52 to drive the support ring 6 to rotate.

[0075] In this embodiment, the design of the bearing seat 5 is further refined, including key components such as the adjustment bracket 51 and the adjustment rollers 52. The adjustment bracket 51, as part of the bearing seat 5, provides a basic structure for the installation and adjustment of the adjustment rollers 52. The number of adjustment rollers 52 is a pair, which are distributed along the direction perpendicular to the axial direction of the rotor shaft 01. Such a layout helps to evenly support the entire support ring 6.

[0076] The main role of the adjustment rollers 52 is to support the support ring 6 and ensure its stability during the rotation of the rotor shaft 01. Since the adjustment rollers 52 are arranged in pairs, they can evenly distribute the weight of the support ring 6, reducing the load on individual rollers, thereby improving the stability and reliability of the entire support structure.

[0077] The setting of the driving and transmission mechanism is another important innovation point of this embodiment. The mechanism is also installed on the adjustment bracket 51 and connected with the adjustment rollers 52. The role of the driving and transmission mechanism is to provide power for the adjustment rollers 52, so that they can drive the support ring 6 to rotate. This design makes the rotation of the support ring 6 more flexible and controllable, facilitating the implementation of the turning detection of the rotor body 02.

[0078] Through the control of the driving and transmission mechanism, the rotation speed and direction of the support ring 6 can be accurately adjusted to adapt to different maintenance needs. For example, when detailed inspection of the rotor body 02 is needed, the rotation speed can be reduced to facilitate the operation of the maintenance personnel; while for the overall turning detection, the rotation speed can be increased to improve the detection efficiency.

[0079] It should be noted that this embodiment does not make specific limitations on the driving principle and transmission structure of the driving and transmission mechanism. The driving and transmission mechanism can take many forms, one of which is to use an electric motor as a power source, which drives the gear to rotate, and then drives the adjustment rollers 52. This electric method has the advantages of simple operation, fast response, etc., and is suitable for occasions that require accurate control of the rotation speed and direction of the support ring 6.

[0080] In addition to electric motors, the drive and transmission mechanism can also take other forms, such as hydraulic motors, pneumatic motors, or manual mechanisms, etc. The specific choice of drive and transmission method can be considered comprehensively according to factors such as actual application scenarios, operational convenience, and maintenance requirements, etc.

[0081] In some embodiments, the support ring 6 is provided with an associated assembly disc 61 and a guide rail 62. The assembly disc 61 is provided with a connecting hole 6102, and a fastener 63 is arranged in the connecting hole 6102 to connect the support ring 6 and the rotor body 02. The guide rail 62 is located on the outer periphery of the assembly disc 61, and the outer periphery of the guide rail 62 cooperates with the adjusting roller 52.

[0082] In this embodiment, the structural design of the support ring 6 is further refined, including the two key parts of the assembly disc 61 and the guide rail 62. The assembly disc 61 is an important component of the support ring 6, and its main function is to provide a flat surface for the assembly and connection of the support ring 6. The assembly disc 61 is provided with a connecting hole 6102, which is used to arrange the fastener 63. The function of the fastener 63 is to tightly connect the support ring 6 and the rotor body 02 together, ensuring that the support ring 6 and the rotor body 02 can rotate as a whole during the turning detection process.

[0083] The design of the connecting hole 6102 allows the fastener 63 to pass through, thereby achieving the fixation of the support ring 6. This design not only provides a simple and effective connection method, but also facilitates installation and disassembly, which is conducive to the smooth progress of maintenance work.

[0084] The guide rail 62 is another important structure on the assembly disc 61, which is located on the outer periphery of the assembly disc 61. The main function of the guide rail 62 is to provide guidance for the adjusting roller 52, ensuring that the adjusting roller 52 can smoothly roll along the predetermined path. The cooperation between the guide rail 62 and the adjusting roller 52 helps to reduce the friction and wear of the adjusting roller 52 during operation, and improves the stability and reliability of the entire support ring 6 rotation.

[0085] Through the cooperation of the assembly disc 61 and the guide rail 62, the support ring 6 not only can realize stable connection with the rotor body 02, but also can ensure accurate guidance during rotation. This design improves the flexibility and durability of the support ring 6 in actual application, making the rolling mill motor turning detection device run more efficiently and stably.

[0086] In some embodiments, the connecting hole 6102 is an oblong hole.

[0087] In this embodiment, the design of the connecting hole 6102 is further optimized to the shape of an oblong hole. This design allows the fastener 63 to have a greater range of adjustment within the connecting hole 6102, facilitating the adaptation of the rotor body 02 of different sizes or installation positions. The oblong hole, compared to the traditional circular hole, provides axial adjustment capability, which is very useful when installing the support ring 6 to different models or sizes of rotor bodies 02.

[0088] In some embodiments, each pair of adjustment rollers 52 is provided with two adjustment roller bodies 521.

[0089] In this embodiment, the design of each pair of adjustment rollers 52 is refined, including two independent adjustment roller bodies 521. Each adjustment roller body 521 can be adjusted independently, and such a design increases the flexibility and adaptability of the adjustment roller 52. This structure enables the adjustment roller 52 to better adapt to the diameter changes or installation errors of the support ring 6, thereby ensuring the stability and balance of the support ring 6 during rotation.

[0090] Each adjustment roller body 521 can be adjusted in various ways, such as by rotation, extension, or using other mechanical adjustment means to change the position and pressure of the roller body 521 in contact with the support ring 6. Such a design helps to achieve more precise adjustments to adapt to support rings 6 of different diameters or to compensate for size changes due to wear.

[0091] In addition, by providing two adjustment roller bodies 521, the load-bearing capacity of the adjustment roller 52 can also be improved to some extent, enabling the adjustment roller 52 to adapt to heavier support rings 6 or more frequent use requirements. This design also helps to extend the service life of the adjustment roller 52 and reduce maintenance costs.

[0092] In some embodiments, the line connecting the center of a pair of adjustment rollers 52 and the center of the support ring 6 forms a triangle.

[0093] In this embodiment, the layout design of the adjustment rollers 52 adopts a triangular geometric configuration, which takes full advantage of the inherent stability of a triangle to enhance the support effect of the support ring 6. By connecting the center points of the adjustment rollers 52 and the center point of the support ring 6 to form a triangle, not only can the stability of the entire support structure be improved to reduce vibration during operation, but also the load on the support ring 6 can be more evenly distributed, reducing the pressure on individual rollers and avoiding accelerated wear of the rollers or support ring due to uneven stress.

[0094] In some cases, the assembly plate 61 and the guide rail 62 in the support ring 6 are both steel plates, and the guide rail 62 is welded and fixed in a bent state on the outer periphery of the assembly plate 61.

[0095] In some embodiments, the first plate turning frame 100 further comprises:

[0096] An adjusting steel plate 4 is provided on the roller support 1, and is located between the bottom of the roller support 1 and the ground.

[0097] The support beam 2 is located at the top of the roller support 1.

[0098] In this embodiment, the design of the first disc frame 100 is further optimized by adding an adjusting steel plate 4 to improve the stability of the structure and the flexibility of adjustment. The adjusting steel plate 4 is arranged between the bottom of the roller support 1 and the ground, which makes the bottom structure of the entire first disc frame 100 more stable, and can be adjusted according to the actual situation of the ground to ensure that the first disc frame 100 always remains in a horizontal and stable state.

[0099] The support beam 2 is located at the top of the roller support 1, which makes the support beam 2 can provide a solid support platform for the roller mounting position 201 and the supporting roller 3. The position of the support beam 2 is also conducive to dispersing the pressure from the supporting roller 3, ensuring the stability and durability of the entire structure.

[0100] In addition, the presence of the adjusting steel plate 4 also allows the height of the first disc frame 100 to be fine-tuned to adapt to different height requirements of the rolling motor rotor shaft 01. This adjustable design makes the first disc frame 100 have better applicability and flexibility, and can adapt to more types of rolling motor maintenance work.

[0101] In some embodiments, the roller support 1 and the support beam 2 are welded and fixed.

[0102] In this embodiment, the connection between the roller support 1 and the support beam 2 adopts the welding fixed way, which provides the entire first disc frame 100 with very high structural stability and strength. Welding is a very effective fixing method, which melts and connects metals together, thus forming a solid connection point after cooling.

[0103] Through welding, there is no movable part between the roller support 1 and the support beam 2, which helps to ensure that the entire first disc frame 100 will not deform or be damaged when subjected to heavy load or impact. Welded connection also helps to prevent failures caused by loose bolts or other fastener failures, thereby improving the reliability of the entire disc frame detection device.

[0104] In some embodiments, the support beam 2 includes a set of parallel side plates 21, the rotating shaft of the supporting roller 3 is inserted into the set of side plates 21 from front to back, and at least part of the wheel body of the supporting roller 3 exceeds the upper edge of the side plates 21.

[0105] In this embodiment, the design of the support beam 2 adopts a set of parallel side plates 21, which provides a structured mounting method for the supporting roller 3. The side plates 21 not only provide space for the front and rear insertion of the rotating shaft of the roller, but also form a stable platform through their parallel arrangement, allowing the supporting roller 3 to evenly bear the weight of the rotor shaft 01.

[0106] The wheel body of the supporting roller 3 is designed to extend beyond the upper edge of the side plate 21, which allows the roller to have a larger contact area with the rotor shaft 01, helping to distribute the pressure on the roller and reduce wear. At the same time, the part of the roller that extends beyond the side plate can provide additional stability to prevent the roller from shifting under high load or impact, while the part inside the side plate is protected by the side plate.

[0107] In a specific embodiment, the device exhibits significant advantages through a carefully designed combination structure, which can adapt to various complex working conditions. Specifically, the use of the first and second turning frames 100 and 200 not only supports the rotor shaft 01 and rotor body 02 of the rolling mill motor, but also achieves the purpose of turning detection and repair through adjustable roller spacing and rotational adjustment of the support ring 6.
