Description

Technical Field

[0001] The invention relates to the technical field of shaft protection components, in particular to a shaft-holding type shaft-belt generator shaft fixing and centering protection component. Background Art

[0002] The shaft-mounted shaft-belt generator is a power generation device used in the field of ships, and the shaft-mounted type refers to an installation method and structural characteristics of the generator. During production, since the shipyard workshop generally does not have the conditions for generator testing, the initially assembled shaft-belt generator needs to be hoisted onto the ship and the shaft system needs to be calibrated. During hoisting or secondary installation of the rotor, the shaft system is still not in a fixed state, which can easily cause shaking and collision with the stator inside the motor. Therefore, a protective component is often used to prevent the shaft and rotor from moving, ensure the gap between the rotor and the stator, and ensure the safety of the shaft system.

[0003] When a traditional shaft-belt generator is hoisted onto a ship to reinstall the rotor and align the shaft system, the shaft system is still not fixed in place, so the shaft and the rotor are easy to shake with the generator casing. In addition, due to the small gap between the rotor and the stator, the rotor and the stator may collide with each other, causing damage to the motor. For example, a utility model patent with announcement number CN220673580U proposes a shaft fixing and alignment protection component for a shaft-belt generator to solve the above problems. During the initial assembly, the operator sets two semicircular rings at the connection between the shaft and the body. The two semicircular rings are The inner diameter of the circle formed by the butted rings is the same as the diameter of the shaft, and the retaining ring between the semicircular ring and the body is used to clamp the shaft. At the same time, a channel steel is installed on the side wall of the hole circumference of the generator shaft through a double-headed screw, and the flange at the end of the shaft and the channel steel are locked with bolts to prevent the shaft from shaking during lifting. When the generator is in place, the screw and the channel steel are removed, and the inner diameter of the semicircular ring is expanded and reinstalled using a machine tool. The operation process is cumbersome, and the bolts need to be repeatedly turned in the process of limiting or canceling the limit of the shaft, which has low operation efficiency and poor flexibility. When installing the shaft generator, it is necessary to ensure that it is accurately aligned with the transmission shaft, coupling and other components. The body of the shaft generator is usually directly fixed to the floor of the cabin with bolts. Since screw holes are pre-opened on the cabin, if there are slight deviations in the position of the screw holes or the size of the shaft generator, engine and other equipment during installation, it will make it difficult to accurately align the generator shaft with other transmission shafts. At this time, it is necessary to repeatedly remove the bolts and reinstall them, or to form screw holes on the cabin floor. The operation process is cumbersome and has poor flexibility. When installing a shaft-driven generator, due to different positions of the ship or different hull structures, there may be height differences in the installation position. In order to ensure that the rotating shaft of the generator is correctly connected to the transmission shaft or other equipment, a base is usually installed at the bottom of the generator using bolts. However, due to different hull structures, bases of different heights need to be replaced, which is not practical. In addition, when the equipment is running, it may produce slight deformation due to temperature changes or loads, while the height of the base remains constant, which can easily cause vibration or damage to the shaft.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 4As shown, a shaft fixing and centering protection assembly of a shaft-holding shaft-belt generator described in the present invention comprises a generator body 1, a mounting structure 2 mounted on the generator body 1, a protection structure 3 connected to the mounting structure 2, a shaft-belt generator shaft 4 mounted on the generator body 1, a first adjustment structure 5 arranged at the bottom of the generator body 1, a height adjustment structure 6 connected to the first adjustment structure 5, and a second adjustment structure 7 matched with the height adjustment structure 6; the mounting structure 2 comprises an end cover 201 and three ears 202 fixedly connected to the edge of the end cover 201, the end of the generator body 1 abuts against the end cover 201, the end cover 201 is matched with the protection structure 3, the protection structure 3 comprises a connecting seat 301 and a rotating seat 302 arranged at the center of the connecting seat 301, the outer side of the end cover 201 is fixedly connected to the connecting seat 301, a retaining frame 303 is provided between the connecting seat 301 and the rotating seat 302, a plurality of balls 304 are sleeved on the retaining frame 303, and the balls 304 is rollingly connected with the inner wall of the connecting seat 301 and the rotating seat 302. The center position of the rotating seat 302 is engaged with a limiting sleeve 307. The top of the limiting sleeve 307 is slidably connected with two limiting blocks 308. A tension spring 309 is fixedly connected between the limiting blocks 308 and the inner wall of the limiting sleeve 307. A shaft-belt generator shaft 4 is provided between the two limiting blocks 308. The shaft-belt generator shaft 4 passes through the limiting sleeve 307. The top of the limiting sleeve 307 is threadedly connected with two knobs 3 11. The inner end of the knob 311 abuts against the limit block 308. A seal 305 is engaged between the bottom surface of the connecting seat 301 and the rotating seat 302. A gray ring 306 is engaged between the top surface of the connecting seat 301 and the rotating seat 302. A rubber pad 310 is fixedly connected to the side of the limit block 308 close to the shaft generator shaft 4. The rubber pad 310 abuts against the shaft generator shaft 4. The limit sleeve 307 is a hexagonal prism structure, and the limit block 308 is an arc structure.Before hoisting the shaft-belt generator to the cabin for installation, it is necessary to first limit the shaft-belt generator shaft 4 (refer to the shaft-belt generator shaft in the patent with announcement number CN220673580U) preliminarily installed on the generator body 1 to avoid collision between the rotor connected thereto and the stator inside the generator due to shaking during hoisting or secondary assembly. First, the shaft-belt generator shaft 4 connected to the rotor is installed inside the generator body 1. Since the gap between the rotor and the stator is small, in order to avoid collision between the two, it is only necessary to use bolts to fix a connecting seat 301 and other components installed thereon at the designated screw holes on the outside of the end cover 201, and then rotate at the same time. The knob 311 at the end of the limit sleeve 307 is threadedly connected to the limit sleeve 307, so that the knob 311 moves toward the inside of the limit sleeve 307 and contacts the limit block 308, driving the limit block 308 to slide in the direction of the shaft generator shaft 4 and stretching the tension spring 309 until the two limit blocks 308 clamp the shaft generator shaft 4. Since the rubber pad 310 is fixed on the side of the limit block 308 close to the shaft generator shaft 4, the friction between the shaft generator shaft 4 and the shaft generator shaft 4 is increased, and the firmness is improved. At this time, the shaft generator shaft 4 is effectively fixed to prevent it from shaking during the lifting process. A tension spring 309 is provided between the inner walls of 7, so that when the knob 311 is rotated to the initial position, the limit block 308 can be retracted into the inside of the limit sleeve 307, so as not to block the movement of the shaft-belt generator shaft 4. Moreover, since the limit sleeve 307 is a hexagonal prism and is engaged with the rotating seat 302, when the internal parts of the limit sleeve 307 are damaged, it is convenient to dismantle it as a whole for repair or replacement, and the flexibility is strong. When the generator body 1 is calibrated for the shaft system, the generator body 1 drives the shaft-belt generator shaft 4 to rotate, the shaft-belt generator shaft 4 drives the limit sleeve 307 to rotate, and the limit sleeve 307 drives the rotating seat 302 to rotate inside the connecting seat 301, thereby realizing the shaft-belt generator. The position of the machine shaft 4 is always limited during its rotation, avoiding the problem of collision between the rotor and the stator caused by vibration during the alignment of the shaft system, and the practicability is strong. Since the ball 304 is provided between the rotating seat 302 and the connecting seat 301 through the retaining frame 303, the friction between the rotating seat 302 and the connecting seat 301 is reduced, which can effectively reduce the friction resistance of the rotating parts during the movement and improve the mechanical efficiency. The bottom surfaces of the connecting seat 301 and the rotating seat 302 are engaged with a seal 305 to avoid dust from entering, and a gray ring 306 is provided between the top surfaces of the two, which not only ensures the sealing performance, but also plays a role in reducing friction, and has strong wear resistance. ;

[0023] Specifically, Figure 1 , Figure 2 and Figure 7As shown, the attachment ear 202 is fixedly connected to the generator body 1 by bolts, and the end of the generator body 1 away from the end cover 201 is fixedly connected with a heat dissipation cover 203; the end cover 201 is covered, so that the attachment ear 202 at the edge of the end cover 201 is aligned with the corresponding position on the generator body 1, and then locked by bolts, which has strong firmness. At the same time, the other end of the generator body 1 is provided with a heat dissipation cover 203, which enhances the overall heat dissipation performance.

[0024] Specifically, Figure 1 and Figure 5-Figure 9As shown, the first adjustment structure 5 includes a bottom plate 501 and a first screw rod 502 rotatably connected to the bottom plate 501. The bottom of the generator body 1 is provided with a bottom plate 501, and two guide rails 503 are slid on the bottom plate 501, one of the guide rails 503 is threadedly connected to the first screw rod 502, and both ends of the guide rails 503 are fixedly connected to a first rack 504, and two mounting frames 505 are slidably connected between the two guide rails 503, and both ends of the mounting frames 505 are fixedly connected to a second rack 506, and the second rack 506 is meshed with the adjacent first rack 504, and a connecting plate 507 is fixedly connected between the two mounting frames 505. A second screw rod 508 is threadedly connected to the center position of the connecting plate 507, and a connecting frame 510 is rotatably connected to the bottom of the second screw rod 508. Two rollers 511 are rotatably connected to the connecting frame 510. The mounting frame 505 is in a "U"-shaped structure, and a rotating block 509 is fixedly connected to the top of the second screw rod 508. In the process of installing the generator body 1, when the positions of the screw holes reserved on the cabin do not correspond or there are differences in the sizes of the equipment, which makes it difficult to accurately align the shaft generator shaft 4 with other transmission shafts, if it is necessary to adjust the lateral position of the generator body 1, it is only necessary to rotate the rotating block 509 at the bottom of the generator body 1 first, and then the rotating block 509 drives the second screw rod 508 to rotate. Since the second screw rod 508 is threadedly connected to the connecting plate 507, and the bottom is rotatably connected to the connecting frame 510, the second screw rod 508 drives the connecting frame 510 to move downward. When the two rollers 511 on the connecting frame 510 hit the bottom plate 501, the connecting plate 507 and the two mounting frames 505 are lifted up for a distance until the second racks 506 at both ends of the mounting frames 505 are no longer engaged with the first racks 504 at the bottom, the generator body 1 can be pushed to move freely on the two guide rails 503 to adjust the position. When it is adjusted to a suitable position, the rotating block 509 on the second screw rod 508 is rotated in the opposite direction so that the rollers 511 at the bottom no longer hit the bottom plate 501, at this time, the second racks 506 at both ends of the mounting frame 505 are meshed with the corresponding positions on the first rack 504 again, so as to effectively fix the positions of the mounting frame 505 and the generator body 1 above, and then use the hexagonal wrench to rotate the first screw rod 502 on the bottom plate 501, and drive the guide rail 503 connected thereto to move freely laterally through the first screw rod 502, and at the same time, change the guide rail 503 to drive another guide rail 503 to move, and then the two guide rails 503 drive the generator body 1 of the above method to move laterally, so as to achieve the purpose of accurately adjusting the lateral position of the generator body 1, which is easy to operate, avoids the problem of repeatedly installing and removing bolts when adjusting the position, and improves the operating efficiency.

[0025] Specifically, Figure 1 and Figure 5-Figure 9As shown, the height adjustment structure 6 includes a first guide column 601 and a height adjustment frame 602 slidably connected to the first guide column 601, wherein both ends of one of the mounting frames 505 are fixedly connected to the first guide column 601, and both ends of the other mounting frame 505 are respectively fixedly connected to another first guide column 601 and a second guide column 607, the second guide column 607 is slidably connected to the adjacent height adjustment frame 602, and a mounting plate 603 is provided above the two height adjustment frames 602, and the mounting plate 603 is matched with the second adjustment structure 7, and a connecting strip 604 is slidably connected between the two mounting plates 603, a support frame 605 is fixedly connected to the connecting plate 507, and a third screw rod 606 is rotatably connected to the support frame 605, and the third screw rod 606 is threadedly connected to the connecting strip 604, and the support frame 605 is in a "U"-shaped structure, and the bottom of the third screw rod 606 is fixedly connected to Another rotating block 509; when it is necessary to adjust the height of the generator body 1, it is only necessary to rotate the other rotating block 509 at the bottom of the generator body 1, and the rotating block 509 drives the third screw rod 606 to rotate on the support frame 605, and at the same time drives the connecting strip 604 and the two mounting plates 603 to move up and down, and the two mounting plates 603 drive the generator body 1 installed on the top through the fixed plate 704 to move up and down, thereby quickly adjusting the height of the generator body 1, which is convenient for accurate alignment of the shaft-belt generator shaft 4 with other transmission shafts, and the operation is simple and efficient. At the same time, in the process of the two mounting plates 603 moving up and down, the mounting plate 603 drives the bottom height adjustment frame 602 to move up and down along the three first guide columns 601 and one second guide column 607, and because the first guide column 601 and the second guide column 607 form a quadrilateral, the stability of the height adjustment frame 602 and the generator body 1 during the up and down movement is enhanced, and the flexibility is strong.

[0026] Specifically, Figure 1 and Figure 5-Figure 9As shown, the second adjustment structure 7 includes a guide rod 701 and a connecting block 702 slidably connected to the guide rod 701, one of the height adjustment frames 602 is fixedly connected to the guide rod 701, the connecting block 702 is slidably connected to the inner wall of the height adjustment frame 602, and the other height adjustment frame 602 is rotatably connected to a fourth screw rod 703, and the fourth screw rod 703 is threadedly connected to another two connecting blocks 702, and a mounting plate 603 is fixedly connected between two adjacent connecting blocks 702, and two fixing plates 704 are fixedly connected to the bottom of the generator body 1, and the fixing plate 704 is fixedly connected to the mounting plate 603; when the generator body needs to be adjusted 1, it is only necessary to use a hexagonal wrench to rotate the fourth screw rod 703 on one of the height adjustment frames 602, and then the fourth screw rod 703 drives the adjacent mounting plate 603 to move freely longitudinally through the two connecting blocks 702, and relative sliding occurs between the mounting plate 603 and the connecting strip 604. At the same time, since the generator body 1 is fixedly connected between the two mounting plates 603, the mounting plate 603 drives the mounting plate 603 on the other side to move longitudinally, and at the same time, the two connecting blocks 702 at the bottom of the mounting plate 603 on the other side slide along the guide rod 701. The setting of the guide rod 701 enhances the overall stability. At this time, the adjustment of the longitudinal position of the generator body 1 is completed, and the operation is simple.

[0027] When the present invention is in use, before the shaft-belt generator is hoisted to the cabin for installation, it is necessary to limit the shaft-belt generator shaft 4 (refer to the shaft-belt generator shaft in the patent with announcement number CN220673580U) preliminarily installed on the generator body 1 to avoid collision between the rotor connected thereto and the stator inside the generator due to shaking during hoisting or secondary assembly. First, the shaft-belt generator shaft 4 connected to the rotor is installed inside the generator body 1, and then the end cover 201 is covered so that the attached ear 202 at the edge of the end cover 201 is aligned with the corresponding position on the generator body 1, and then it is locked with bolts, which has strong firmness. At the same time, a heat dissipation cover 203 is provided at the other end of the generator body 1 to enhance the overall heat dissipation performance. The gap between the stator and the shaft cover 201 is small. To avoid collision between the two, it is only necessary to use bolts to fix a connecting seat 301 and other components installed thereon at the designated screw holes on the outside of the end cover 201, and then simultaneously turn the knob 311 at the end of the limit sleeve 307. Since the knob 311 is threadedly connected to the limit sleeve 307, the knob 311 moves toward the inside of the limit sleeve 307 and contacts the limit block 308, driving the limit block 308 to slide toward the direction of the shaft generator shaft 4 and stretching the tension spring 309 until the two limit blocks 308 clamp the shaft generator shaft 4. Moreover, since a rubber pad 310 is fixed on the side of the limit block 308 close to the shaft generator shaft 4, the friction between the limit block 308 and the shaft generator shaft 4 is increased, thereby improving the firmness. At this time, the shaft generator shaft 4 is effectively fixed to prevent it from shaking during the lifting process, and because a tension spring 309 is provided between the limit block 308 and the inner wall of the limit sleeve 307, when the knob 311 is rotated to the initial position, the limit block 308 is contracted to the inside of the limit sleeve 307, so as not to block the movement of the shaft generator shaft 4, and because the limit sleeve 307 is a hexagonal prism and is engaged with the rotating seat 302, when the internal parts of the limit sleeve 307 are damaged, it is convenient to remove it as a whole for maintenance or replacement, and it has strong flexibility. When the generator body 1 is calibrated for the shaft system, the generator body 1 drives the shaft generator shaft 4 to rotate, the shaft generator shaft 4 drives the limit sleeve 307 to rotate, and the limit sleeve 307 drives the rotating seat 30 2 rotates inside the connecting seat 301, so that the position of the shaft generator shaft 4 is always limited during its rotation, avoiding the problem of collision between the rotor and the stator caused by vibration during the alignment of the shaft system, and having strong practicality. Moreover, since a ball 304 is arranged between the rotating seat 302 and the connecting seat 301 through the retaining frame 303, the friction between the rotating seat 302 and the connecting seat 301 is reduced, which can effectively reduce the friction resistance of the rotating parts during the movement process and improve the mechanical efficiency. Moreover, a seal 305 is engaged with the bottom surface of the connecting seat 301 and the rotating seat 302 to avoid dust from entering, and a Gly ring 306 is arranged between the top surfaces of the two, which not only ensures the sealing performance, but also plays a role in reducing the friction, and has strong wear resistance. During the installation of the generator body 1, when the positions of the screw holes reserved on the cabin do not correspond or there are differences in the sizes of the equipment, making it difficult to accurately align the shaft-belt generator shaft 4 with other transmission shafts, if it is necessary to adjust the lateral position of the generator body 1, it is only necessary to first rotate the rotating block 509 at the bottom of the generator body 1, and then the rotating block 509 drives the second screw rod 508 to rotate. Since the second screw rod 508 is threadedly connected to the connecting plate 507, and the bottom is rotatably connected to the connecting frame 510, the second screw rod 508 drives the connecting frame 510 to move downward. When the two rollers 511 on the connecting frame 510 hit the bottom plate 501, and the connecting plate 507 and the two mounting frames 505 are lifted up for a distance until the second racks 506 at both ends of the mounting frame 505 are no longer engaged with the first rack 504 at the bottom, the generator body 1 can be pushed at this time so that the generator body 1 is between the two The position can be adjusted by freely moving on the guide rail 503. When it is adjusted to a suitable position, the rotating block 509 on the second screw rod 508 is rotated in the opposite direction so that the roller 511 at the bottom no longer contacts the bottom plate 501. At this time, the second racks 506 at both ends of the mounting frame 505 are meshed with the corresponding positions on the first rack 504 again, so as to effectively fix the position of the mounting frame 505 and the generator body 1 above. Then, the first screw rod 502 on the bottom plate 501 is rotated by using a hexagonal wrench, and the guide rail 503 connected thereto is driven to move freely horizontally by the first screw rod 502. At the same time, the guide rail 503 drives another guide rail 503 to move, and then the two guide rails 503 drive the generator body 1 of the above method to move horizontally, so as to achieve the purpose of accurately adjusting the horizontal position of the generator body 1. The operation is simple, and the problem of repeatedly installing and removing bolts when adjusting the position is avoided, thereby improving the operation efficiency. When the height of the generator body 1 needs to be adjusted, it is only necessary to rotate another rotating block 509 at the bottom of the generator body 1, and the rotating block 509 drives the third screw rod 606 to rotate on the support frame 605, and at the same time drives the connecting strip 604 and the two mounting plates 603 to move up and down, and the two mounting plates 603 drive the generator body 1 installed on the top through the fixing plate 704 to move up and down, so as to quickly adjust the height of the generator body 1, and facilitate the accurate alignment of the shaft-belt generator shaft 4 with other transmission shafts, which is easy to operate and has high operating efficiency. At the same time, in the process of the two mounting plates 603 moving up and down, the mounting plate 603 drives the bottom height adjustment frame 602 to move up and down along the three first guide columns 601 and one second guide column 607, and because the first guide column 601 and the second guide column 607 form a quadrilateral, the stability of the height adjustment frame 602 and the generator body 1 during the up and down movement is enhanced, and the flexibility is strong; When the longitudinal position of the generator body 1 needs to be adjusted, it is only necessary to use a hexagonal wrench to rotate the fourth screw rod 703 on one of the height adjustment frames 602, and then the fourth screw rod 703 drives the adjacent mounting plate 603 to move freely longitudinally through the two connecting blocks 702, and relative sliding occurs between the mounting plate 603 and the connecting strip 604. At the same time, since the generator body 1 is fixedly connected between the two mounting plates 603, the mounting plate 603 drives the mounting plate 603 on the other side to move longitudinally, and at the same time, the two connecting blocks 702 at the bottom of the mounting plate 603 on the other side slide along the guide rod 701. The setting of the guide rod 701 enhances the overall stability. At this time, the adjustment of the longitudinal position of the generator body 1 is completed, and the operation is easy.
