Description

Technical Field

[0001] The present invention relates to the technical field of rail vehicles, and in particular to a wheel turning and repairing method, device, equipment and computer-readable storage medium. Background Art

[0002] During actual operation, the wheels of rail vehicles inevitably wear and deform due to interaction with the rails. As this wear and deformation accumulate, the unevenness of the wheel's circumferential surface gradually increases, causing high-frequency vibrations and even affecting the safe operation of the vehicle. Therefore, regular wheel turning and repair, which involves cutting and grinding, is necessary.

[0003] During wheel lapping, the tread thickness of the wheel is inevitably reduced, and the tread thickness also wears during operation, eventually reducing the tread thickness of the wheel to the point where it is unusable. Currently, wheel lapping is mainly performed based on the lapping cycle and the thickness of the tread cut each time, which are determined based on the experience of the staff. However, the lapping parameters determined in this way cannot guarantee the optimal lapping method for the wheel, which in turn leads to unreasonable lapping methods. Summary of the Invention

[0046] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0047] Reference Figure 1 , Figure 1 A schematic flow chart of a wheel turning method provided in an embodiment of the present application, wherein the wheel turning method may include:

[0048] S101: Collecting the initial wheel rim thickness and initial tread thickness of the wheel.

[0049] Reference Figure 2 , Figure 2 This is a schematic diagram of a partial cross-section of a wheel. During the operation of the wheel, the tread and the wheel flange will rub against the rail and gradually reduce.

[0050] S102: Determine, based on the initial wheel flange thickness and the initial tread thickness, the total mileage of the wheel when the tread thickness of the wheel is turned to less than a minimum thickness under different turning feed amounts and different turning cycles.

[0051] Among them, the turning feed amount is the amount of cutting on the tread thickness during each turning; the turning cycle is the mileage the wheel runs between two adjacent turnings.

[0052] S103: The wheel is turned according to the turning feed amount and turning cycle corresponding to the maximum total mileage.

[0053] For rail vehicles, their wheels constantly rub against the rails during operation, causing the wheels to deform and the shape of the wheels to no longer meet the requirements for safe operation. For this reason, the wheels need to be regularly turned and repaired using tools. During the turning and repair process, the thickness of the end face of the wheel will be further reduced. With multiple turning and repair of the wheels and the wear of the wheel tread during operation, the tread thickness of the wheel will gradually decrease until it is unusable, at which point the service life of the wheel ends.

[0054] Obviously, when a wheel reaches the end of its service life, the greater the mileage it has traveled, the longer its service life will be, and the highest utilization rate and economic benefit of the wheel will be.

[0055] Regarding the amount of lathe feed and the lathe cycle, theoretically, a longer lathe cycle means more total mileage, which is equivalent to reducing the number of lathes and, in turn, the thickness of the wheel tread removed during lathes. A smaller lathe feed also reduces the thickness of the wheel tread removed during lathes, which theoretically increases the total mileage.

[0056] However, in practice, to ensure that the wheel's deformation meets the required deformation requirements, a longer turning cycle requires a greater turning feed. Conversely, a smaller turning feed requires a shorter turning cycle. This suggests that the turning cycle and turning feed are mutually exclusive in terms of increasing wheel life. To maximize wheel life, a balance must be struck between turning feed and turning cycle to ensure maximum wheel mileage.

[0057] To this end, the present application plans the turning feed amount and turning cycle for each wheel turning based on the entire service life of the wheel, sets different turning feed amounts and turning cycles, and accordingly determines the total mileage of the wheel under each turning feed amount and turning cycle condition. When the total mileage is the largest, it means that the corresponding turning feed amount and turning cycle are the optimal parameters for turning the wheel. According to the turning feed amount and turning cycle, the service life of the wheel can be extended to the greatest extent, the utilization rate of the wheel can be maximized, and the rationality of wheel turning can be improved.

[0058] Optionally, the process of selecting and setting the turning feed amount and turning cycle, and determining the total mileage corresponding to each set of different turning feed amounts and turning cycles may include:

[0059] S201: According to the initial wheel flange thickness, a set of turning feed amounts and turning cycles for each turning are sequentially set under the condition that the wheel flange thickness after each turning is greater than the sum of the minimum wheel flange thickness and the wheel flange wear.

[0060] It is understood that each wheel lathing process corresponds to a lathing feed and a lathing cycle. This is because as a wheel's mileage increases or its operating conditions change, setting the lathing feed and lathing cycle for each lathing process allows for more precise settings of the wheel lathing process, further ensuring maximum wheel utilization.

[0061] In addition, refer to Figure 2Every time a wheel is repaired by lathing, the main task is to cut the tread thickness of the wheel; however, during the operation of the wheel, its rim will inevitably wear out, causing the rim thickness to become smaller and smaller. When the rim thickness is too small, it is also necessary to expand the rim by lathing the tread thickness. Therefore, when actually setting the lathing feed amount of the wheel tread, it is necessary to consider whether the rim thickness corresponding to each lathing needs to be expanded. If the rim thickness is not worn too much and is thick enough, the setting of the lathing feed amount will not be affected by the rim thickness; when the rim thickness is worn more, it is necessary to set an appropriate lathing feed amount to meet the rim thickness requirements.

[0062] Optionally, a set of turning feed amount and turning cycle for each turning is set to satisfy the condition that the wheel flange thickness after each turning is greater than the sum of the minimum wheel flange thickness and the wheel flange wear, including:

[0063] Set the cutting feed of the i-th turning to meet h i ≥α·(L min -L i-1 +ΔL i ·S i ), where α is the proportional constant, L min is the minimum thickness of the rim, ΔL i is the wheel flange wear rate between the i-1th turning and the i-th turning, S i-1 is the turning cycle between the i-1th turning and the i-th turning, L i To meet L i -ΔL i+1 ·S i+1 ≤L min The rim thickness of the wheel corresponding to the i-th turning is completed, i∈[1,n].

[0064] After completing the i-1th turning repair, when determining the turning repair cycle and turning repair feed amount of the i-th turning repair, the turning repair feed amount and turning repair cycle can be set first in this process. After determining the turning repair cycle, judge L i -ΔL i+1 ·S i+1 ≤L min If so, the rim wear generated during the turning cycle from the i-1th turning to the i-th turning causes the rim thickness after the i-th turning to be reduced to less than the minimum rim thickness before the i+1th turning. In this case, the turning feed during the i-th turning needs to increase the rim thickness. Therefore, according to h i ≥α·(L min -L i-1 +ΔL i ·S i ) Set the turning feed amount and turning cycle.

[0065] As mentioned above, when setting the turning feed amount and turning cycle for each turning, in addition to meeting the requirements of the wheel rim thickness, the deformation problem generated during the operation of the wheel pair should also be further considered.

[0066] Therefore, in another optional embodiment of the present application, the process of sequentially setting a set of turning feed amounts and turning cycles for each turning operation may include:

[0067] Step 1: Based on the current mileage of the wheel and the corresponding tread wear rate and rim wear rate, simulate the operation process of the wheel after the next turning process to determine the turning feed amount for the next turning process and the value range corresponding to the turning cycle.

[0068] Step 2: Set the next turning feed amount and turning cycle according to the corresponding value range.

[0069] Step 3: Based on the sum of the next turning cycle and the current running mileage as the new current running mileage, re-execute the steps of simulating the running process of the wheel after the next turning according to the current running mileage of the wheel, the tread wear rate and the rim wear rate corresponding to the current running mileage, and determine the turning feed amount of the next turning and the value range corresponding to the turning cycle, until the tread thickness of the wheel corresponding to the current number of turnings completed is less than the minimum tread thickness.

[0070] It is understandable that if the currently set turning feed amount and turning cycle are the turning feed amount and turning cycle corresponding to the first turning of a brand new wheel, the corresponding current running mileage is 0.

[0071] In addition, the tread wear rate and the rim wear rate both change with the mileage that the wheels have traveled, so generally they first increase and then decrease with the increase in mileage. This specific relationship can be determined by collecting a large amount of historical mileage and corresponding wear rates for big data statistical analysis to determine the accurate corresponding relationship, which will not be elaborated on here.

[0072] Because the mileage of the corresponding wheels is different each time they are turned, different tread wear rates and rim wear rates should be used for each turning cycle to calculate the tread wear and rim wear to ensure the accuracy of the two wear amounts.

[0073] During the simulation of the wheel operation process, the operation process of the wheel within the turning cycle can be simulated based on the set turning feed amount and turning cycle. As the wheel surface is worn, the wear and deformation of the wheel can be simulated. During the simulation process, a threshold value of the wheel shape parameter can be set. When Fangzheng determines that the shape parameters of the wheel wear and deformation are within the safe range defined by the threshold value, the set turning feed amount and turning cycle are feasible. The types of wheel shape parameters and the corresponding threshold values ​​can be set by the staff based on work experience, or determined by data analysis of the impact of wheel deformation on the operation process. This application does not impose any specific restrictions on this.

[0074] In order to determine the value range of the turning feed amount and the turning cycle, different turning feed amounts and different turning cycles can be selected for the same current running mileage, and the value range of the two can be finally determined.

[0075] S202: Determine the tread wear rate in the next lathing cycle according to the mileage of the wheel corresponding to each lathing cycle, and use the product of the tread wear rate and the next lathing cycle as the tread wear amount corresponding to the next lathing cycle.

[0076] S203: Determine the total number of turning operations when the wheel tread thickness decreases to less than the minimum tread thickness based on the initial tread thickness and the sum of the turning feed amount and the tread wear amount corresponding to each turning operation.

[0077] During operation, a wheel undergoes a turning cycle, and the reduction in tread thickness between a turning cycle and a turning cycle is equal to the turning feed and the tread wear. As a wheel undergoes multiple turning cycles and a turning cycle, the tread thickness gradually decreases. The total reduction is the cumulative sum of the turning feeds and the tread wear during each turning cycle. The difference between the initial tread thickness and the total reduction is the final tread thickness.

[0078] S204: When the wheel undergoes a total number of lapping cycles, the total number of lapping cycles performed is summed to obtain a total mileage.

[0079] When the total number of lappings is determined, the number of lapping cycles of the wheel can also be determined, and the total mileage of the wheel can be obtained by accumulating the various lapping cycles of the wheel.

[0080] S205: Based on the initial rim thickness, and under the condition that the rim thickness after each turning is greater than the sum of the minimum rim thickness and the rim wear, a set of turning feed amounts and turning cycles for each turning are updated in sequence, and the steps of determining the tread wear rate in the next turning cycle according to the mileage completed by the wheel corresponding to each turning, and determining the tread wear corresponding to the next turning cycle according to the product of the tread wear rate and the next turning cycle are performed, and the total mileage corresponding to each set of turning feed amounts and turning cycles is obtained.

[0081] Based on the above discussion, in another optional embodiment of the present application, the wheel is turned based on the turning feed amount and turning cycle corresponding to the maximum total mileage, and further includes:

[0082] According to the turning feed amount and turning cycle, and the initial tread thickness, the theoretical tread thickness corresponding to the number of times the wheel has been turned is determined, and the actual tread thickness corresponding to the number of times the wheel has been turned is collected;

[0083] When the difference between the theoretical tread thickness and the actual tread thickness bracket is greater than the difference threshold, the wheel turning feed amount and turning cycle are re-determined.

[0084] Taking into account that there may be deviations between the actual wheel turning and the set turning, such as errors between multiple turnings, inaccurate tread wear rate and other different factors that lead to a large deviation between the actual wheel turning and the set turning, the wheel turning feed amount and turning cycle can be reset at this time to achieve more accurate and reasonable planning of the wheel turning.

[0085] To sum up, in this application, the turning feed amount and turning cycle of the wheel throughout its entire service life cycle are comprehensively planned, different turning feed amounts and turning cycles are set, and the total mileage corresponding to the wheel under each turning feed amount and turning cycle is correspondingly determined. When the total mileage is the largest, it means that the corresponding turning feed amount and turning cycle are the optimal parameters for turning the wheel; the wheel is turned with the turning feed amount and turning cycle corresponding to the maximum mileage of the wheel, so that the turning method of the wheel is more reasonable, the maximum service life of the wheel is guaranteed, and the utilization rate of the wheel is improved.
