Description

Technical Field

[0001] The present invention relates to the technical field of centering detection, and in particular to a bearing centering adjustment method and system. Background Art

[0002] As ships increasingly move toward higher power and larger tonnage, alignment issues between large equipment during ship assembly are becoming increasingly prominent, particularly in turbine and generator bearing alignment. Facing the high-precision installation requirements, failure to meet these requirements can severely impact the ship's power generation efficiency and lead to operational issues such as abnormal noise and wear and fatigue.

[0003] During modern ship assembly, bearing alignment is typically performed on the slipway using traditional methods such as horizontal shaft alignment, optical instrument alignment, and force measurement, which can maintain a certain level of process accuracy. However, after the ship is launched and put into operation, maintaining high alignment accuracy becomes difficult due to differences in the forces acting on the hull in the water and on the slipway, as the ship's course changes. Furthermore, when aligning on the slipway, slipway deformation can affect alignment accuracy, necessitating adjustments to the bearing alignment.

[0004] Currently, bearing realignment is typically performed after a ship is launched by manually adjusting the height of shims. However, due to the weight and bulk of this equipment, adjustment efficiency is low, and achieving the required alignment accuracy is difficult, seriously impacting the efficiency and quality of ship shafting assembly. Therefore, a bearing alignment method and system are urgently needed to address these issues. Summary of the Invention

[0040] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0041] Figure 1 The following is a flow chart of the bearing alignment adjustment method provided by this paper, as shown in Figure 1As shown, the present invention provides a bearing alignment adjustment method, comprising:

[0042] Step 101: Acquire multiple positive stress data sets, wherein each positive stress data set is composed of positive stress data of each axial position of the bottom of the bearing corresponding to the first device and the second device when the first device and the second device are in different positions; the bearings of the first device and the second device are connected by a coupling.

[0043] The bearings of the steam turbine and generator are connected by couplings, and the bearings have been aligned on the slipway before the ship is officially launched. After the ship is launched, as the navigation conditions change, such as turbulence caused by bad weather, the alignment accuracy of the bearings of the steam turbine and generator will inevitably change, and the bearings need to be adjusted. In the present invention, multiple positive stress sensors can be pre-installed at the bottom of each bearing (such as the bottom of the bearing seat) of the first device (i.e., the steam turbine) and the second device (i.e., the generator), so that the positive stress generated at each position of the bottom of the bearings of the two devices can be collected in real time.

[0044] Furthermore, in the present invention, a plurality of hydraulic support columns are provided at the bottom of the housing of the first device and the second device. When performing alignment adjustment, the gear positions of all the hydraulic support columns are raised and lowered. Since the postures of the first device and the second device change during each gear adjustment process (e.g., each hydraulic support column is in a different gear position, causing the device to tilt), the horizontality and position of their corresponding bearings are also adjusted accordingly. After the hydraulic support column completes each gear raising and lowering operation, the stress sensor collects the normal stress data once to form a corresponding normal stress data set under different gear combinations. For example, in one embodiment, the bottom of the housing of the steam turbine and the generator are each provided with three hydraulic support columns, each hydraulic support column having two lifting and lowering gear positions (e.g., upshift and downshift). By raising and lowering the gear positions of the hydraulic support columns, eight sets of normal stress data sets under different gear combinations can be obtained. It should be noted that the present invention is not limited to the specific application scenarios of the bearing alignment adjustment method provided, and is also applicable to scenarios other than the alignment adjustment of bearings of marine steam turbines and generators, such as the alignment adjustment between bearings of various equipment in industrial scenarios.

[0045] Step 102 : Compare the normal stress data sets, and determine the target postures corresponding to the first device and the second device respectively according to the comparison results.

[0046] In the present invention, step 101 constructs a set of normal stress data for the first and second devices in different posture combinations (i.e., different gear combinations of the hydraulic support columns) based on the normal stress data at various axial positions on the bottom of the bearing when the first and second devices are in different postures. A variance or standard deviation is then calculated for each normal stress data set, and based on the calculated results, an optimal set of normal stress data sets is determined. Based on this optimal set of normal stress data, the corresponding gear combination of the hydraulic support columns is then obtained, thereby determining the target posture of the vessel within the current time period, corresponding to the gear combination of the first and second devices.

[0047] Step 103: Based on the target postures corresponding to the first device and the second device respectively, perform bearing alignment adjustment on the first device and the second device.

[0048] In the present invention, after the target posture is determined, the gear position of the hydraulic support column is adjusted according to the gear position combination corresponding to the target posture, so that after the adjustment, the bearing alignment adjustment of the first device and the second device is completed.

[0049] The bearing alignment adjustment method provided by the present invention obtains the normal stress data of various axial positions of the bottom of the bearings of the turbine and the generator when they are in different posture states, compares the normal stress data sets corresponding to each posture state, and determines the target posture of the steam turbine and the generator based on the comparison results, thereby adjusting the posture state of the steam turbine and the generator to the target posture to complete the bearing alignment adjustment, making the alignment adjustment process more efficient and having higher alignment accuracy.

[0050] Based on the above embodiment, a plurality of stress sensors are provided at various positions along the axial direction on the bottom of the bearing corresponding to each of the first device and the second device; a plurality of identical hydraulic support columns are provided on the bottom of the housing corresponding to each of the first device and the second device, and each of the hydraulic support columns has multiple gear positions;

[0051] The obtaining of multiple normal stress data sets includes:

[0052] receiving a plurality of first inputs, wherein the first inputs include operations for adjusting the gear positions of the respective hydraulic support columns, and the gear position combinations corresponding to the respective first inputs are different;

[0053] In response to each of the first inputs in sequence, the gear position of each of the hydraulic support columns is adjusted to the target gear position corresponding to each of the first inputs, and after each response to the first input, the positive stress data of the first device and the second device in the current posture are collected through the multiple stress sensors to obtain positive stress data sets for different gear position combinations.

[0054] In the present invention, the alignment adjustment of the bearings of the steam turbine and generator of a ship is used for illustration. First, m stress sensors are evenly deployed along the axial direction at the bottom of the bearings of the steam turbine and the generator (the bottom is the bottom of the bearing seat), and a set of data collectors are configured to measure the positive stress of each position of the bearing bottom along the axial direction in real time; then, n hydraulic support columns are distributed at the bottom of the steam turbine and the generator, and each hydraulic support column is set with k lifting gears within the allowable adjustment range, and a set of joint controllers are configured to adjust the horizontality and position of the bearings of the steam turbine and the generator, that is, the position adjustment of the steam turbine and the generator is achieved by adjusting the gears of the hydraulic support columns; then, during the assembly process, a communication connection is established between the data collector and the joint controller, and k lifting gears of each hydraulic support column are measured respectively. n Under the combination of lifting and lowering gears, m normal stress data at each position along the axial direction of the bottom of the bearing are obtained; finally, based on each lifting and lowering gear combination, the corresponding normal stress data set is constructed.

[0055] Based on the above embodiment, the steps of comparing the normal stress data sets and determining the target postures corresponding to the first device and the second device according to the comparison results include:

[0056] Based on the normal stress data in each of the normal stress data sets, obtaining the normal stress data variance corresponding to each of the gear combinations;

[0057] Comparing the variances of the normal stress data to obtain the minimum normal stress data variance, and determining the gear combination corresponding to the minimum normal stress data variance as the target gear combination;

[0058] Based on the target gear combination, target postures corresponding to the first device and the second device are obtained.

[0059] In the present invention, the variance S of the m positive stress data in each positive stress data set is calculated to determine the target posture of the first device and the second device corresponding to the optimal gear combination. The present invention adjusts the posture of the steam turbine and the generator so that the positive stress at each axial position of the bearing bottom is more uniform, and the variance S of the measured positive stress data is smaller. The shift position corresponding to the minimum value of the variance S is the optimal gear combination. Based on the posture corresponding to this optimal gear position as the target posture, the posture of the steam turbine and the generator is adjusted to the target posture to improve the bearing alignment accuracy of the steam turbine and the generator. In one embodiment, corresponding to each shift position combination, the calculation formula for measuring the variance S of the m positive stress data in the gear combination is as follows:

[0060]

[0061] Where i = 1, 2…m, F i is the normal stress data of the bearing bottom along the axial direction measured by the i-th stress sensor, F p is the average value of m normal stress data measured at various axial positions at the bottom of the bearing.

[0062] Through the calculation formula of the above variance S, after determining the target posture, the optimal gear combination setting of each hydraulic support column is performed through the joint controller; finally, after the ship is launched, the stress data is collected regularly through the stress sensor, and the k n The bearing alignment under each combination of lifting and lowering gears is detected and analyzed, and the optimal gear combination setting is updated according to the analysis results, thereby ensuring the stability of the bearing alignment accuracy during the long-term navigation of the ship.

[0063] Based on the above embodiment, after obtaining the plurality of normal stress data sets, the method further includes:

[0064] According to the number of the hydraulic support columns and the number of the gear positions, obtaining the number of combinations corresponding to all the gear position combinations;

[0065] The obtaining, based on the normal stress data in each of the normal stress data sets, the normal stress data variance corresponding to each of the gear combinations includes:

[0066] When it is determined that the number of the acquired plurality of normal stress data sets is equal to the number of combinations, receiving a second input, the second input comprising performing a calculation operation of a variance of the normal stress data;

[0067] In response to the second input, the normal stress data variance corresponding to each of the gear combinations is calculated based on the normal stress data in each of the normal stress data sets.

[0068] In the present invention, the number n of hydraulic support columns installed at the bottom of the turbine and generator casing and the number k of gears of each hydraulic support are first obtained. It should be noted that in the present invention, in order to facilitate the bearing alignment adjustment process, each hydraulic support column is of the same model, that is, each hydraulic support column has the same gear. Further, based on the number of hydraulic support columns and the number of gears, the number k of lifting and lowering gear combinations is determined. n Therefore, in the next bearing alignment adjustment cycle, after determining that the normal stress data under each gear combination of the hydraulic support column are collected, the normal stress data analysis is started, that is, the variance of the normal stress data corresponding to each gear combination is calculated, and the bearing alignment adjustment is automatically started.

[0069] Figure 2 The schematic diagram of the ship bearing alignment adjustment process provided by the present invention can be referred to Figure 2 As shown, the bearings 206 of the steam turbine 204 and the generator 205 are connected by a coupling 203, and m stress sensors 201 are evenly distributed along the axial direction at the bottom of the bearing 206 (m is generally greater than 6, that is, at least three stress sensors 201 are set at the bottom of each bearing 206 of the steam turbine 204 and the generator 205), and a set of data collectors are configured to measure the normal stress at various axial positions at the bottom of the bearing 206 in real time; then, n hydraulic support columns 202 are distributedly distributed at the bottom of the casings of the steam turbine 204 and the generator 206, each hydraulic support column 202 is set with k lifting gears within the allowable adjustment range, and a set of joint controllers are configured to adjust the horizontality and position of the bearings of the steam turbine 204 and the generator 205.

[0070] Furthermore, during the assembly process, a communication connection is established between the data collector and the joint controller, and the stress sensors 201 are used to measure the k lifting and lowering positions of the n hydraulic support columns 202. n Under the combination of lifting and lowering gears, m positive stress data at various axial positions of the bottom of the bearing 206 are collected, and the variance S of the m positive stress data in different gear combinations is calculated. In the present invention, the higher the bearing alignment accuracy of the turbine 204 and the generator 205, the more uniform the positive stress at various axial positions of the bottom of the bearing, and the smaller the variance of the measured positive stress data. Therefore, the lifting and lowering gear corresponding to the minimum value of the variance S is taken as the optimal gear combination. After the optimal gear combination is set for each hydraulic support column 202 through the joint controller, the bearing alignment adjustment is completed.

[0071] Based on the above embodiment, before acquiring a plurality of normal stress data sets, the method further includes:

[0072] The normal stress data is judged, and if a deviation value between the normal stress data and preset normal stress data is greater than or equal to a preset threshold, the normal stress data is deleted as abnormal data.

[0073] In the present invention, to improve the efficiency of centering adjustment, abnormal normal stress data can be deleted by setting a preset threshold. For example, based on the relationship between the deviation value between the collected normal stress data and the preset normal stress data (such as the set standard normal stress data) and the preset deviation value, if the deviation value exceeds the preset deviation value, it can be determined that the normal stress data is abnormal and needs to be eliminated. In one embodiment, a maximum normal stress threshold and a minimum normal stress threshold can also be set for judgment, and data exceeding the maximum normal stress threshold or less than the minimum normal stress threshold is also deleted.

[0074] The bearing centering adjustment system provided by the present invention is described below. The bearing centering adjustment system described below and the bearing centering adjustment method described above can be referenced to each other.

[0075] Figure 3 The structural diagram of the bearing centering adjustment system provided by the present invention is as follows: Figure 3 As shown, the present invention provides a bearing alignment adjustment system, including a positive stress data acquisition module 301, a data processing module 302 and a bearing alignment module 303, wherein the positive stress data acquisition module 301 is used to obtain multiple positive stress data sets, wherein each of the positive stress data sets is composed of positive stress data of each axial position of the bottom of the bearing corresponding to the first device and the second device when the first device and the second device are in different postures; the bearings of the first device and the second device are connected by a coupling; the data processing module is used to compare each of the positive stress data sets, and determine the target posture corresponding to the first device and the second device according to the comparison result; the bearing alignment module 303 is used to perform bearing alignment adjustment on the first device and the second device based on the target posture corresponding to the first device and the second device.

[0076] In the present invention, a plurality of normal stress sensors can be pre-installed at the bottom of each bearing (e.g., the bottom of the bearing seat) of the first device (i.e., the steam turbine) and the second device (i.e., the generator), so that the normal stress generated at each position of the bottom of the bearing of the two devices can be collected in real time through the normal stress data acquisition module 301. Specifically, in the present invention, a plurality of hydraulic support columns are provided at the bottom of the housing of the first device and the second device. When performing centering adjustment, the gear positions of all the hydraulic support columns are raised and lowered. Since the posture of the first device and the second device changes during each gear adjustment (e.g., each hydraulic support column is in a different gear position, causing the device to tilt), the horizontality and position of each corresponding bearing are also adjusted accordingly. After the hydraulic support column completes each gear raising and lowering operation, the normal stress data is collected once by the normal stress data acquisition module 301 to form a corresponding normal stress data set under different gear combinations.

[0077] Furthermore, the data processing module 302 calculates the variance or standard deviation of each normal stress data set, thereby determining the optimal set of normal stress data based on the calculated results. Based on this optimal normal stress set, the corresponding gear combination of the hydraulic support column is obtained. This determines the target position of the first and second devices during the current time period. After determining the target position, the bearing alignment module 303 adjusts the gear position of the hydraulic support column according to the gear combination corresponding to the target position, thereby completing the bearing alignment adjustment of the first and second devices.

[0078] The bearing alignment adjustment system provided by the present invention obtains the normal stress data of various axial positions of the bottom of the bearings of the turbine and the generator when they are in different posture states, compares the normal stress data sets corresponding to each posture state, and determines the target posture of the steam turbine and the generator based on the comparison results, thereby adjusting the posture state of the steam turbine and the generator to the target posture to complete the bearing alignment adjustment, making the alignment adjustment process more efficient and having higher alignment accuracy.
