Abstract
Description
Technical Field
[0001] This utility model relates to the field of generator bearing housing installation and calibration technology, and in particular to a generator bearing housing horizontal calibration structure. Background Technology
[0002] During generator installation and maintenance, the horizontal alignment of the bearing housing is one of the core procedures. The bearing housing axis must be strictly aligned with the main shaft axis. If there is a deviation (such as vertical tilt or horizontal offset), the unit will experience periodic vibration, accelerated bearing wear, and excessive noise during operation. In severe cases, it may even lead to the bending of the main shaft and the shutdown of the unit. Bearing housing alignment can achieve horizontal alignment of the axis and eliminate deviations caused by manufacturing and installation errors.
[0003] Currently, the horizontal calibration of generator bearing housings mostly uses dial indicators and shims. Operators need to repeatedly adjust the thickness of the shims at the bottom or side of the bearing housing and monitor the axis deviation with a dial indicator. The calibration accuracy depends entirely on manual experience, which can easily lead to substandard calibration due to operational errors. Moreover, each calibration takes a long time, resulting in low calibration efficiency.
[0004] To address this, a horizontal calibration structure for generator bearing housing is proposed. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-6 The present invention provides the following technical solution:
[0029] A generator bearing housing horizontal calibration structure includes a mounting base 1, a calibration bracket 2 and a bearing housing body 3 are provided on the top of the mounting base 1, lifting cylinders 4 are bolted to both sides of the bottom of the calibration bracket 2, spirit levels are bolted to both sides of the top of the calibration bracket 2, and a controller is bolted to the left side of the calibration bracket 2. A horizontal calibration structure 5 for use with the bearing housing body 3 is provided inside the calibration bracket 2, and a monitoring component 6 is bolted to the rear side of the inner wall of the calibration bracket 2. The front side of the monitoring component 6 extends into the interior of the bearing housing body 3 and is coaxial with its axis.
[0030] The horizontal calibration structure 5 includes two longitudinal lead screws 51, which are rotatably connected to both sides inside the calibration bracket 2. The surface of the longitudinal lead screw 51 is threaded with a longitudinal threaded sleeve 52, and a fixing plate 53 is bolted to the bottom of the longitudinal threaded sleeve 52. Adjusting plates 54 are slidably arranged at both ends of the fixing plate 53, and a connecting plate 55 is bolted to the other side of the adjusting plate 54. A support block 56 is bolted to the bottom of the connecting plate 55, and a transverse adjustment component 57 is rotatably connected between the two support blocks 56 on both sides.
[0031] In this embodiment: the calibration bracket 2 is installed on the top of the mounting base 1 via the lifting electric cylinder 4, and the bearing seat body 3 is placed inside the calibration bracket 2, ensuring that the horizontal calibration structure 5 corresponds to the bearing seat body 3. The lifting electric cylinder 4 is activated by the controller to adjust the height of the calibration bracket 2 so that the level bubble shows that the calibration bracket 2 is horizontal, completing the initial positioning. The controller controls the rotation of the two longitudinal lead screws 51, and the longitudinal screw sleeve 52 moves along the longitudinal lead screws 51, driving the fixed plate 53, adjusting plate 54, connecting plate 55 and support block 56 to move longitudinally in sync. This can simultaneously drive the lateral adjustment component 57 and the bearing seat body 3 to move, adjusting the longitudinal position of the bearing seat body. The lateral adjustment component 57 pushes the bearing seat body 3 to move laterally, while monitoring the feedback data of the monitoring component 6, until the bearing seat body 3 is horizontal and the axis is aligned. By integrating the lifting electric cylinder 4, the horizontal calibration structure 5 and the monitoring component 6, a calibration process of height adjustment, level adjustment and accuracy monitoring is formed, eliminating the need to operate multiple tools separately, improving calibration accuracy and efficiency.
[0032] Specifically, such as Figure 2 , Figure 3 As shown, the lateral adjustment assembly 57 includes a lateral lead screw 571, which is rotatably connected between two support blocks 56. A lateral threaded sleeve 572 is threaded onto the surface of the lateral lead screw 571, and a support plate 573 is bolted to the side of the lateral threaded sleeve 572 near the bearing housing body 3.
[0033] Specifically, such as Figure 3 As shown, a pressure plate 574 is provided on the side of the support plate 573 away from the transverse threaded sleeve 572, and the side of the pressure plate 574 close to the bearing housing body 3 is in close contact with it.
[0034] Specifically, such as Figure 3 As shown, two first servo electric cylinders 575 in a V-shape are hinged between the pressure plate 574 and the support plate 573, and an anti-slip pad is provided between the pressure plate 574 and the bearing seat body 3.
[0035] In this embodiment: by setting a lateral adjustment component 57, the controller controls the extension and retraction of the first servo cylinder 575 to adjust the angle of the pressure plate 574, so that the pressure plate 574 is completely in contact with the outer wall of the bearing seat body 3, while the anti-slip pad is in close contact with the bearing seat body 3. After the longitudinal adjustment is completed, the lateral lead screw 571 of the lateral adjustment component 57 is in the lateral corresponding position of the bearing seat body 3, and the controller starts the servo motor at the right end of the lateral lead screw 571. The servo motor drives the lateral lead screw 571 to rotate, and the lateral threaded sleeve 572 moves along the lateral lead screw 571, driving the support... Plate 573, pressure plate 574, and bearing housing body 3 move laterally. Based on the axial deviation data fed back by monitoring component 6, the moving direction and distance of the lateral threaded sleeve 572 are controlled until the lateral position of bearing housing body 3 meets the horizontal alignment requirements. Furthermore, since the first servo electric cylinder 575 is arranged in a V-shape, the extension and retraction of the two electric cylinders can not only control the height of one end of the contact plate, but also fine-tune the posture of the contact plate. Through the precise coordination of the four electric cylinders, the tilt of bearing housing body 3 can be corrected in both the front-back and left-right directions, achieving a multi-directional adjustment effect.
[0036] Specifically, such as Figure 1 As shown, servo motors are bolted to the front end of the longitudinal lead screw 51 and the right end of the transverse lead screw 571, and the servo motors are bolted to the calibration bracket 2 and the support block 56 respectively on the side closer to them.
[0037] Specifically, such as Figure 6 As shown, studs 7 are bolted to the opposite side of the two adjusting plates 54 on both sides, and the side of the studs 7 away from the adjusting plate 54 extends to the outside of the fixing plate 53. The surface of the studs 7 is threaded with a fixing sleeve 8, and the side of the fixing sleeve 8 close to the fixing plate 53 is in close contact with it.
[0038] In this embodiment: by setting the servo motor, the servo speed is controllable, which can realize micro-adjustment (such as millimeter-level displacement) to meet the high-precision calibration requirements. By setting the stud 7 and the fixing sleeve 8, the adjustment plate 54 can slide freely. With the locking function of the stud 7 and the fixing sleeve 8, the position of the support block 56 can be quickly adjusted to adapt to bearing seat bodies 3 of different widths.
[0039] Specifically, such as Figure 4 As shown, the monitoring component 6 includes a sliding seat 61, which is bolted to the rear side of the inner wall of the calibration bracket 2. A telescopic rod 62 is bolted to the front side of the sliding seat 61, and a second servo electric cylinder 63 is bolted to the front side of the telescopic rod 62. A fixed rod 64 is connected to the front side of the second servo electric cylinder 63 through a ball joint structure, and a laser positioner 65 is bolted to the front side of the fixed rod 64. The laser beam of the laser positioner 65 is projected onto the reference mark on the generator main shaft.
[0040] Specifically, such as Figure 4As shown, a fixing sleeve 66 is sleeved on the surface of the fixing rod 64, and a positioning electric cylinder 67 is bolted to the surface of the fixing sleeve 66 in an annular shape. A positioning plate 68 is bolted to the other end of the positioning electric cylinder 67, and the other side of the positioning plate 68 is in close contact with the inner wall of the bearing seat body 3.
[0041] In this embodiment: by setting up the monitoring component 6, the controller controls the extension and retraction of the second servo cylinder 63 to adjust the front and rear position of the laser positioner 65, so that the laser positioner 65 extends into the bearing housing body 3. The positioning cylinder 67 extends and pushes the positioning plate 68 towards the inner wall of the bearing housing body 3 until multiple positioning plates 68 are tightly attached to the inner wall of the bearing housing body 3 from different directions, fixing the position of the laser positioner 65. Through the hinge between the fixing rod 64 and the second servo cylinder 63, and the setting of the sliding seat 61 and the telescopic rod 62, the laser positioner 65 can move synchronously with the horizontal calibration structure 5. This facilitates real-time monitoring of the adjustment position of the horizontal calibration structure 5. The laser positioner 65 emits a laser beam, which is projected onto the reference mark on the generator main shaft. The deviation between the bearing housing body 3 and the main shaft axis is fed back in real time. If the laser beam deviates from the reference mark, the controller controls the horizontal calibration structure 5 to adjust the position of the bearing housing body 3 according to the direction of the deviation until the laser beam is precisely aligned with the reference mark. At the same time, the spirit level is observed to ensure that the bearing housing body 3 is level. The laser positioner 65 can provide real-time feedback on the axis alignment, with an accuracy far exceeding that of manual observation of a dial indicator. This avoids monitoring distortion caused by visual errors and improves monitoring accuracy.
[0042] Specifically, such as Figure 5 As shown, a mounting plate 9 is bolted to the top of the lifting electric cylinder 4. The top of the mounting plate 9 is bolted to the inner wall of the calibration bracket 2. A support plate 10 is provided at the bottom of the mounting plate 9. The top of the lifting electric cylinder 4 passes through the interior of the support plate 10.
[0043] Specifically, such as Figure 5 As shown, the support plate 10 has a fixing section 11 bolted to the front and rear sides of the bottom, and the bottom of the fixing section 11 is threaded with an adjustable foot 12.
[0044] In this embodiment: the height of the calibration bracket 2 can be smoothly adjusted by the lifting electric cylinder 4, avoiding structural tilting or collision caused by manual lifting, and ensuring operational safety; the adjustable foot 12 is threadedly connected to the fixed section 11, and the height can be adjusted independently. Even if there is a slope or protrusion on the mounting base 1, the support plate 10 can be kept horizontal by adjustment, ensuring that the calibration bracket 2 itself is horizontal, avoiding calibration deviation caused by base surface problems, and improving calibration accuracy.
[0045] Working principle: When calibrating the bearing housing body 3, first place the calibration bracket 2 on the mounting base 1, rotate the adjustable feet 12 at the bottom of the fixed section 11, and adjust the height of each adjustable foot 12 individually according to the flatness of the mounting base 1. Observe the level bubble at the top of the calibration bracket 2 until the level bubble shows that the support plate 10 and the calibration bracket 2 are level as a whole, thus completing the adaptation to the mounting base 1 and avoiding subsequent calibration deviations due to unevenness of the base. The height of the calibration bracket 2 is adjusted by the lifting electric cylinder 4 to keep the laser positioner 65 aligned with the bearing housing axis. Then, the bearing housing body 3 is placed on the mounting base 1 and positioned between the two lateral adjustment components 57, and then controlled by the controller. The first servo cylinder 575 is used to extend and retract to adjust the angle of the pressure plate 574, so that the pressure plate 574 is completely in contact with the outer wall of the bearing housing body 3, and is fixedly connected to the bearing housing body 3 and the lateral adjustment assembly 57. Then, the controller controls the second servo cylinder 63 and the fixing rod 64 to move forward, so that the laser positioner 65 on the front side of the fixing rod 64 extends into the bearing housing body 3, and the positioning cylinders 67 distributed in a ring on the fixing sleeve 66 (fitted onto the surface of the fixing rod 64) are activated. The positioning cylinders 67 extend and push the positioning plates 68 towards the inner wall of the bearing housing body 3 until multiple positioning plates 68 are tightly in contact with the inner wall of the bearing housing body 3 from different directions. At this time, the positioning cylinders 67 stop running. Positioner 65 is stably fixed inside bearing housing 3. Then, laser positioner 65 is activated, projecting the laser beam onto the reference mark on the generator main shaft to initially establish the axis alignment monitoring reference. Finally, the controller sends a signal to the servo motor at the front end of longitudinal lead screw 51. The servo motor drives longitudinal lead screw 51 to rotate, and longitudinal sleeve 52 moves along the surface of longitudinal lead screw 51, thereby driving the bottom bolted fixing plate 53 to move longitudinally in sync. Through adjusting plate 54 and connecting plate 55, it drives support block 56 and transverse adjusting assembly 57 to move longitudinally in sync until bearing housing 3 completes longitudinal adjustment. Then, the controller activates the servo motor at the right end of transverse lead screw 571, and the servo motor drives transverse lead screw 571 to rotate. The transverse threaded sleeve 572 moves along the transverse lead screw 571, thereby driving the support plate 573 and the pressure plate 574 to move the bearing housing body 3 laterally. During this process, the feedback from the laser positioner 65 is observed in real time. If the laser beam deviates from the reference mark of the generator main shaft, the controller adjusts the direction and speed of the servo motor according to the deviation direction, and controls the moving direction and distance of the transverse threaded sleeve 572. If the laser beam shows that the bearing housing body 3 is slightly tilted, it is corrected by the differential extension and retraction of the V-shaped first servo cylinder 575 until the laser beam is accurately projected onto the reference mark of the generator main shaft, completing the horizontal calibration of the bearing housing body 3. Finally, the bearing housing body 3 is fixed by using shims, bolts and other structures.
[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
