[0002] Currently, in the field of generator installation and maintenance, different models of generators have different shaft alignment requirements, and each needs to be equipped with a dedicated generator alignment device. Existing generator alignment devices can only be adapted to a single specific specification of generator, and cannot flexibly cope with the diverse needs of various generators. This not only leads to increased procurement costs, but also wastes storage resources. Moreover, frequently changing the matching tooling for generators is both time-consuming and costly. Utility Model Content

[0003] Therefore, it is necessary to provide a generator centering device to address the issues of poor versatility and high cost.

[0004] This application provides a generator centering device, comprising: a main frame having a fixing hole extending along a first direction; a driving member disposed on the main frame for driving the main frame to move back and forth along the first direction; a fastening member for fastening an external generator, the fastening member being disposed on the bottom side of the main frame; and a fixing bolt passing through the fixing hole and fixed to the fastening member.

[0005] In one embodiment, there are two fixing holes, which are spaced apart along a second direction; the second direction is perpendicular to the first direction; there are two fixing bolts, which pass through the corresponding fixing holes and are fixedly connected to the buckle.

[0006] In one embodiment, a partition is formed in the middle of each of the fixing holes to divide the fixing hole into two independent elongated holes.

[0007] In one embodiment, the fastener includes two L-shaped fasteners and a connecting plate; the two L-shaped fasteners are spaced apart from each other along a second direction; the second direction is perpendicular to the first direction; the connecting plate is connected between the two L-shaped fasteners, the connecting plate is attached to the bottom side of the main frame, and the fixing bolt passes through the fixing hole and is fixed to the connecting plate.

[0008] In one embodiment, the ends of the two L-shaped buckles away from the connecting plate are both oriented toward the drive member along the first direction.

[0009] In one embodiment, the main frame includes an upright plate and a main body, the upright plate being erected at one end of the main body along the first direction, and the fixing hole being disposed at the other end of the main body along the first direction; the driving member is connected to the upright plate.

[0010] In one embodiment, the driving member is a screw, and the upright plate has a screw hole; the driving member is screwed into the screw hole.

[0011] In one embodiment, the main frame includes a reinforcing plate that is diagonally braced between the upright plate and the main body.

[0012] In one embodiment, the generator alignment device further includes a pad; the pad is supported below the end of the main frame away from the fixing hole.

[0013] In one embodiment, the main frame is a steel frame.

[0014] The beneficial effects are:

[0015] This application provides a generator alignment device comprising a main frame, a drive component, a latching component, and fixing bolts. The main frame has fixing holes extending along a first direction, facilitating the adjustment of the latching component's position along this direction. This allows the latching component to easily engage with an external generator. The fixing bolts pass through the fixing holes and are fixed to the latching component, ensuring relative fixation. When the drive component moves the main frame back and forth along the first direction, the main frame moves the latching component back and forth along the same direction, thereby adjusting the generator's position and completing the generator shaft alignment process. Thus, by designing the latching component to adjust its position along the extension direction of the fixing holes, the generator alignment device can precisely adjust according to different generator shaft alignment requirements, enabling rapid adaptation and switching between multiple generator models. This significantly improves the compatibility and versatility of the generator alignment device, effectively avoiding redundant procurement and storage, and effectively reducing costs.

[0029] This application provides a generator alignment device for fixing to an external generator and adjusting its position to achieve alignment and installation.

[0030] Figure 1This is a schematic diagram of the generator centering device provided in some embodiments of this application. Figure 2 This is a schematic diagram of the structure of a snap fastener provided in some embodiments of this application. Figure 3 This is a schematic diagram of the main frame provided for some embodiments of this application.

[0031] See Figures 1 to 3 As shown, the generator alignment device includes: a main frame 10, a drive component 20, a snap-fit ​​component 30, and a fixing bolt 40.

[0032] The main frame 10 has a fixing hole 11 extending along a first direction X. A driving member 20 is disposed on the main frame 10 and is used to drive the main frame 10 to move back and forth along the first direction X. A fastening member 30 is used to fasten an external generator and is disposed on the bottom side of the main frame 10; a fixing bolt 40 passes through the fixing hole 11 and is fixed to the fastening member 30.

[0033] In related technologies, different models of generators have different shaft alignment requirements, and each needs to be equipped with a dedicated generator alignment device. Existing generator alignment devices can only be adapted to a single specific specification of generator, and cannot flexibly cope with the diverse needs of various generators. This not only leads to increased procurement costs, but also wastes storage resources. Moreover, frequently changing the matching tooling for generators is both time-consuming and costly.

[0034] In this embodiment, a main frame 10, a drive component 20, a latching component 30, and a fixing bolt 40 are provided. The main frame 10 has a fixing hole 11 extending along the first direction X, which facilitates the adjustment of the latching component 30 along the first direction X, thereby enabling the latching component 30 to easily engage with an external generator. The fixing bolt 40 passes through the fixing hole 11 and is fixed to the latching component 30, making them relatively fixed. When the drive component 20 drives the main frame 10 to move back and forth along the first direction X, the main frame 10 can drive the latching component 30 to move back and forth along the first direction X, thereby adjusting the position of the generator and completing the generator shaft alignment process. Thus, by designing the latching component 30 to adjust its position along the extension direction of the fixing hole 11, the generator alignment device can be precisely adjusted according to different generator shaft alignment requirements, realizing rapid adaptation and switching of multiple generator models, greatly improving the compatibility and versatility of the generator alignment device, effectively avoiding duplicate procurement and storage, and effectively reducing costs.

[0035] In one embodiment, the main frame 10 is a steel frame, which has good structural strength and low cost.

[0036] In some possible embodiments, see Figures 1 to 3As shown, there are two fixing holes 11, which are spaced apart along the second direction Y; the second direction Y is perpendicular to the first direction X. There are two fixing bolts 40, which pass through the corresponding fixing holes 11 and are fixedly connected to the fastener 30.

[0037] Thus, by setting two fixing holes 11 spaced apart along the second direction Y, and cooperating with two fixing bolts 40 that pass through the corresponding fixing holes 11 and are fixedly connected to the buckle 30, the buckle 30 is subjected to more uniform force when it moves and adjusts along the first direction X, effectively preventing deflection or loosening that may occur due to single-point fixing, ensuring that the generator maintains a stable posture during the adjustment process, thereby improving the accuracy and reliability of shaft alignment; furthermore, it can enhance the structural stability and position adjustment accuracy of the generator alignment device, and prevent skew caused by single-point fixing.

[0038] Furthermore, by setting two fixing holes 11 and two fixing bolts 40, the fastener 30 can adapt to the external structural features of different generator models. By flexibly adjusting the position of the two fixing bolts 40 within the elongated fixing holes 11, the fastener 30 can achieve fine-tuning capability in the second direction Y, further expanding the adaptability range of the generator alignment device. Ultimately, this effectively improves the compatibility of the generator alignment device with different generator specifications, enabling it to quickly complete the switching and alignment operations of multiple models without changing tooling. This reduces the cost of purchasing various specialized equipment, reduces warehousing pressure, and shortens the commissioning time, comprehensively improving the efficiency and economy of the generator alignment process.

[0039] In some possible embodiments, see Figures 1 to 3 As shown, a partition 15 is formed in the middle of each fixing hole 11 to divide the fixing hole 11 into two independent elongated holes 16.

[0040] By forming a partition 15 in the middle of each fixing hole 11, the fixing hole 11 is divided into two independent elongated holes 16, which improves the structural strength of the main frame 10 and effectively prevents frame deformation or stress concentration problems that may be caused by excessively long continuous holes when tightening the fixing bolts 40 or bearing generator load, thereby ensuring the dimensional stability and durability of the device in long-term repeated use.

[0041] In addition, the relatively small length of the elongated hole 16 along the first direction X can reduce the possible sliding distance of the fixing bolt 40 in the fixing hole 11, thereby reducing the shaking of the generator; the additional support provided by the partition 15 greatly improves the shear resistance and locking reliability of the connection point, ensuring that the connection of the generator is stable during the alignment process and subsequent operation, without the risk of displacement.

[0042] In some possible embodiments, see Figures 1 to 3As shown, the fastener 30 includes two L-shaped fasteners 31 and a connecting plate 32. The two L-shaped fasteners 31 are arranged at intervals relative to each other along the second direction Y; the second direction Y is perpendicular to the first direction X; the connecting plate 32 is connected between the two L-shaped fasteners 31, and the connecting plate 32 is attached to the bottom side of the main frame 10. The fixing bolt 40 passes through the fixing hole 11 and is fixed to the connecting plate 32.

[0043] The fastener 30 can be made of metal, such as stainless steel or carbon steel.

[0044] The fastener 30 constructs a stable, efficient, and universal generator fastening structure by employing two L-shaped fasteners 31 arranged at relative intervals along the second direction Y and a connecting plate 32 connecting the two. That is to say, the two L-shaped fasteners 31 are hooked from above a specific base on the generator, ensuring the symmetry and balance of the fastening force of the fastener 30 on the generator. This effectively prevents the generator from detaching or tilting on one side during alignment or operation, greatly improving the safety and reliability of the connection.

[0045] The L-shaped buckle 31 and the connecting plate 32 can be formed by integral bending, resulting in good connection strength.

[0046] The connecting plate 32, as a key connecting and force transmission component, can integrate two independent L-shaped buckles 31 into a sturdy whole, which is convenient to manufacture and has high strength.

[0047] The connecting plate 32 is flat and designed to fit snugly against the bottom of the main frame 10 for easy force application. The fixing bolts 40 pass through the fixing holes 11 and are locked to the connecting plate 32. The connecting plate 32 can be provided with two fixing screw holes 33 corresponding to the fixing bolts 40, facilitating locking with two fixing bolts 40. This allows the driving force from the drive component 20 to be smoothly and evenly transmitted through the main frame 10 and the fixing bolts 40 to the entire snap-fit ​​component 30, ultimately acting on the generator without twisting. This ensures the accuracy of shaft alignment adjustment, enabling quick and stable installation and disassembly of the generator, simplifying the operation process. Furthermore, its excellent adaptability and force transmission characteristics make it a core guarantee for the universality and high precision of the generator alignment device, ultimately significantly improving the equipment's compatibility, reliability, and efficiency.

[0048] In some possible embodiments, see Figures 1 to 3 As shown, the ends of the two L-shaped buckles 31 that are away from the connecting plate 32 are both oriented towards the drive member 20 along the first direction X.

[0049] The ends of the two L-shaped clips 31 that are away from the connecting plate 32 are free ends that can be used with an external generator.

[0050] By setting the free end to face the drive member 20 in the first direction X, the force path of the generator during the centering process can be optimized.

[0051] When the driving component 20 drives the main frame 10 to move back and forth along the first direction X, the main frame 10 can drive the buckle 30 to move back and forth along the first direction X, and then the free end hooks the generator to move back and forth along the first direction X, thereby adjusting the position of the generator and completing the generator shaft alignment process. As a result, the generator alignment device can be precisely adjusted according to the different generator shaft alignment requirements, realize the rapid adaptation and switching of multiple generator models, greatly improve the compatibility and versatility of the generator alignment device, effectively avoid duplicate procurement and storage, and effectively reduce costs.

[0052] In some possible embodiments, see Figures 1 to 3 As shown, the main frame 10 includes an upright plate 12 and a main body 13. The upright plate 12 is erected at one end of the main body 13 along the first direction X, and the fixing hole 11 is provided at the other end of the main body 13 along the first direction X. The driving member 20 is connected to the upright plate 12.

[0053] Specifically, the driving component 20 can be a screw, and the vertical plate 12 has a screw hole 121; the driving component 20 is screwed into the screw hole 121.

[0054] The main body 13 is plate-shaped. The upright plate 12 and the main body 13 can be fixed by welding, which is simple in structure and has high connection strength. Multiple side plates (not shown) can also be set around the main body 13 and welded to the upright plate 12 to form a three-dimensional geometric structure, thereby improving the overall structural rigidity.

[0055] The main frame 10 includes an upright plate 12 and a main body 13 with fixing holes 11. The driving component 20 is specifically a screw that engages with the screw hole 121 on the upright plate 12. By rotating the screw, the rotation of the driving component 20 is converted into a force that drives the upright plate 12 to move back and forth in the first direction X. The structure is simple and stable, and easy to maintain. The upright plate 12 drives the main body 13, and the main body 13 drives the buckle 30 to move back and forth in the first direction X, thereby adjusting the position of the generator and completing the generator shaft alignment process. Thus, by designing the buckle 30 to adjust its position along the extension direction of the fixing hole 11, the generator alignment device can be precisely adjusted according to the different generator shaft alignment requirements, realizing rapid adaptation and switching of multiple generator models. This greatly improves the compatibility and versatility of the generator alignment device, effectively avoids duplicate procurement and storage, and effectively reduces costs.

[0056] In some possible embodiments, see Figures 1 to 3 As shown, the main frame 10 includes a reinforcing plate 14, which is diagonally braced between the upright plate 12 and the main body 13.

[0057] The reinforcing plate 14 can be fixed to the upright plate 12 and the main body 13 by welding, which is simple in structure and has high connection strength.

[0058] By setting a reinforcing plate 14 between the upright plate 12 and the main body 13, the overall structural rigidity and stability of the main frame 10 are significantly enhanced. The reinforcing plate 14 can effectively resist the huge lateral force and bending moment generated by the drive component 20 during the jacking process, prevent bending deformation or stress concentration at the connection between the upright plate 12 and the main body 13, and ensure that the driving force is accurately and losslessly transmitted to the main body 13 along the first direction X. Then, the upright plate 12 can drive the main body 13, and the main body 13 can drive the fastener 30 to move back and forth along the first direction X, thereby adjusting the position of the generator and completing the shaft alignment process of the generator.

[0059] In some possible embodiments, see Figures 1 to 3 As shown, the generator alignment device also includes a pad 50; the pad 50 is supported below the end of the main frame 10 away from the fixing hole 11.

[0060] The pad 50 can be a metal pad, a wooden pad, or a plastic pad.

[0061] By supporting the pad 50 under the end of the main frame 10 away from the fixing hole 11, the pad 50 provides reliable bottom support for the drive end of the main frame, significantly increasing the contact area between the generator alignment device and the generator mounting surface. This prevents the entire device from tilting up at the front end or overturning due to excessive lever arm when the drive component 20 applies thrust, ensuring the smoothness and safety of the generator during alignment adjustment. Ultimately, this effectively improves the stability and environmental adaptability of the generator alignment device.

[0062] Understandably, the thickness of the pad 50 can be selected or adjusted according to the actual height of the workbench or generator on site. This allows the pad 50 to compensate for the difference in reference height when installing different models of generators, ensuring that the main frame 10 always remains horizontal or in the best working position, thereby guaranteeing the accuracy of the drive component 20's propulsion stroke and centering precision.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
