Detailed Description

The present application is described in further detail below with reference to figures 1-8.

The embodiment of the application discloses a vehicle bogie overhauling method, as shown in figure 1, comprising the following steps:

s101, acquiring a bogie model corresponding to a vehicle to be overhauled;

s102, matching a corresponding historical overhaul plan according to the type of the bogie;

s103, analyzing the historical maintenance plan to obtain corresponding maintenance task items of the bogie;

s107, updating a historical maintenance plan according to the bogie maintenance change task item, and generating a corresponding change maintenance movement plan;

and S108, correlating the changed maintenance plan and the bogie model to generate a corresponding target scheduling plan.

In practical application, the bogie maintenance is a part of vehicle maintenance, a bogie maintenance area is specially arranged to maintain each part of the bogie, and all welding of the bogie is subjected to flaw detection and detection. The corresponding overhaul items are as follows: the bogie detecting device comprises a bogie detecting explorator, a bogie overturning machine, a bogie cleaning room and a bogie part cleaning machine, and the bogie is disassembled and assembled by using a trench. The bogie overhaul area can also be used for completing frame repair welding and repair, bogie static load tests and the like, and a process stock path is required to be arranged in the work area for storing the bogie to be repaired and repaired.

The bogie model in step S101 is a specific model of a bogie corresponding to the current vehicle to be overhauled, wherein the bogie has various types due to different performances, structures, parameters, materials, processes and the like, and the main differences of the various types of bogies are represented in the aspects of the number of axles, the axle weight, the axle box positioning mode, the elastic damping device mode, the load transmission mode and the like.

Therefore, it can be seen from the above that different types of bogies have different maintenance plans, and the maintenance plan is also made according to the difference in performance, structure, parameters, materials, processes, and the like of each bogie type and the actual difference in the number of axles, axle weight, axle box positioning manner, elastic vibration damping device form, and load transmission manner, that is, the historical maintenance plan in step S102.

For example, the parts of the motor car bogie are numerous, and the maintenance process for the motor car bogie is quite complicated, so that the stations on the bogie maintenance conveying line of the motor car bogie maintenance base are numerous. The main overhauling process of the A-type motor car bogie can be roughly divided into the following steps: warehousing, cleaning and drying the motor car bogie; decomposing parts of the motor car bogie; checking, testing and maintaining the performance of each part of the disassembled bogie; assembly line of the motor car bogie; and (3) testing the overall performance of the bogie after the assembly of the motor car bogie is finished, namely forming a historical maintenance plan of the motor car bogie of the type A by the maintenance process types.

Further, in order to analyze the obtained historical maintenance schedule, a corresponding truck maintenance task item is obtained, for example, the truck maintenance task item is an inspection, a performance test and a maintenance of each component of the disassembled truck, and the method includes: checking the fastening state of each fastening piece, and preventing loosening; checking the connection part of the axle box pull rod square shaft, the axle box body and the framework, wherein a gap of 3-8mm is kept at the bottom of the groove; checking the connection part of the square shaft of the traction rod and the vehicle body, wherein the bottom of the groove of the square shaft of the traction rod is required to keep a clearance of 2-5 mm; checking whether the gap between the brake shoe and the wheel tread is within the range of 5-8 mm; checking whether the gap between the end of the brake lever and the brake hand wheel is between 0.5 and 1.5; checking the lowest position of the gearbox from the track surface by 120mm; checking whether the foundation brake is operating well; and (5) checking the oil leakage condition of the gear box, allowing oil leakage, and avoiding oil leakage and the like.

And further judging that the overhaul data difference between the current overhaul data and the historical overhaul data corresponding to the bogie overhaul task item exceeds a preset overhaul data difference threshold interval.

Specifically, the historical overhaul data corresponding to the bogie overhaul task item refers to overhaul data of a history detection storage record of the bogie of the type according to the corresponding bogie overhaul task item, under the general condition, the running speed, the stability and the safety of the subway vehicle are directly determined by the performance of the bogie, the bogie is a pressure-resistant part of the subway vehicle and is easy to be influenced by the external environment to generate various fault problems along with the increasing scale of urban traffic construction and faces higher pressure, and therefore the damage condition and the fault problems of all parts in the vehicle bogie in the actual running process can be observed through the historical overhaul data.

The overhaul data difference refers to the difference between the current overhaul data and the corresponding historical overhaul data, the preset overhaul data difference threshold interval refers to the difference range allowed between the current overhaul data and the corresponding historical overhaul data, and if the difference range is exceeded, it is indicated that the bogie component corresponding to the current overhaul data is seriously damaged, and the corresponding overhaul plan needs to be adjusted.

For example, the bogie overhaul task item is an overhaul axle box pull rod square shaft, an axle box body and a framework connection part, a 3-8mm gap is kept at the bottom of a groove of the bogie overhaul task item, current overhaul data is obtained through detection of the to-be-detected vehicle bogie, the current overhaul data is the axle box pull rod square shaft, the axle box body and the framework connection part, the gap at the bottom of the groove is 10mm, historical overhaul data corresponding to the current overhaul data is displayed, the axle box pull rod square shaft and the framework connection part, the gap at the bottom of the groove is kept at 5mm, the overhaul data difference is obtained to be 5mm, a preset overhaul data difference threshold value interval corresponding to the bogie overhaul task item is +/-3 mm, the overhaul data difference between the current overhaul data and the historical overhaul data corresponding to the current overhaul data exceeds a preset overhaul data difference threshold value interval, the situation that the connection between the axle box body and the framework connection part is abnormal is shown, and the overhaul process standard corresponding to the bogie overhaul task item is further obtained according to the overhaul data difference.

Specifically, the overhaul process standard refers to an adjustment and modification standard of a bogie overhaul task item corresponding to a part when the overhaul data difference between the current overhaul data corresponding to the bogie part and the historical overhaul data of the bogie part exceeds a corresponding preset overhaul data difference threshold interval. For example, the bogie overhaul task item S is a place where a square tie rod shaft of an overhaul axle box is connected with an axle box body and a framework, the bottom of a groove of the overhaul axle box should keep a gap of 3-8mm, the corresponding overhaul frequency is 2 weeks and 1 time, the overhaul frequency can be obtained according to the overhaul process standard corresponding to the bogie overhaul task item S, and when the gap where the square tie rod shaft of the overhaul axle box is connected with the axle box body and the framework, namely the current overhaul data exceeds 5 +/-3 mm, the overhaul frequency corresponding to the bogie overhaul task item S is adjusted to be 1 week and 1 time.

For another example, through the detection of the vehicle bogie to be detected, the current maintenance data is obtained as the connection position of the axle box pull rod square shaft, the axle box body and the framework, the gap at the bottom of the groove is 6mm, the maintenance data difference between the current maintenance data and the corresponding historical maintenance data does not exceed the corresponding preset maintenance data difference threshold interval, and the system or related workers continue to maintain other parts of the bogie according to other bogie maintenance task items in the historical maintenance plan.

Further, according to the maintenance process standard, the maintenance frequency of the bogie maintenance task item of 2 weeks and 1 times is modified into 1 week and 1 time, a corresponding bogie maintenance variation task item is generated, a historical maintenance plan corresponding to the bogie maintenance task item is updated according to the bogie maintenance variation task item, a corresponding variation maintenance plan is generated, a bogie model corresponding to the bogie is associated, and a target scheduling plan corresponding to the bogie model is generated, wherein the target scheduling plan is a maintenance scheduling plan formed by modifying and adjusting the historical maintenance plan of the bogie of the model.

The target scheduling plan can inform relevant maintenance personnel in real time in multiple modes, the target scheduling plan can be displayed through a station billboard, the relevant maintenance personnel can be informed in real time, the station billboard can adopt a touch display screen, operation instructions of the maintenance personnel are convenient, the operation instructions can be connected with a handheld maintenance terminal in a wireless communication mode, information interaction between a system and the handheld maintenance terminal is achieved, and the plan change is displayed for the relevant maintenance personnel.

The method for overhauling the vehicle bogie provided by the embodiment is characterized in that a corresponding historical overhauling plan is obtained according to the model matching of the current bogie, so that the overhauling task items of the bogie corresponding to all parts of the vehicle bogie of the model can be obtained through the historical overhauling plan, the vehicle bogie can be further overhauled according to the overhauling task items of the bogie, the current overhauling data corresponding to all parts of the vehicle bogie is obtained, if the overhauling data difference between the current overhauling data and the historical overhauling data corresponding to the overhauling task items of the bogie exceeds the difference threshold interval of the corresponding preset overhauling data, the condition that the bogie parts corresponding to the current overhauling data are abnormal is shown, a further system can make adaptive modification and adjustment on the overhauling task items according to the overhauling process standard corresponding to the abnormal bogie parts at the first time, an overhauling task item which meets the actual overhauling requirement of the abnormal bogie parts is generated, a corresponding historical overhauling plan which is updated according to the obtained overhauling task item and is associated with the model corresponding to the current bogie, a final target scheduling plan is generated, the actual overhauling task item can be adjusted according to the actual overhauling requirement of the bogie parts, and the corresponding overhauling task item can be updated according to the obtained by the obtained corresponding overhauling resources of the bogie, and further abnormal overhauling resources can be modified.

In one embodiment of the present embodiment, as shown in fig. 2, matching the corresponding historical service plan at step S102, i.e., according to the bogie model, includes the steps of:

s201, identifying the type of a bogie, and acquiring an operation time recording table corresponding to a vehicle to be overhauled;

s202, acquiring a window-empty period corresponding to a vehicle to be overhauled according to the operation time record table;

s203, acquiring a corresponding empty window time period in an empty window period;

s204, if the number of the empty window time periods is multiple, judging whether each empty window time period is overlapped;

s205, if the empty window time periods are overlapped, acquiring corresponding overlapped time periods;

s206, if the number of the overlapping time periods is multiple, judging whether the same overlapping time period exists in the multiple overlapping time periods;

s207, if the same overlapping time periods exist in the multiple overlapping time periods, calculating a target proportion corresponding to the same overlapping time periods;

and S208, setting maintenance time priority corresponding to each overlapped time period according to the target proportion, and generating a corresponding maintenance time scheduling table, wherein the target proportion is in direct proportion to the maintenance time priority.

In practical application, in order to reduce the occupied normal operation time of the vehicle to be overhauled, the operation time recording table corresponding to the vehicle to be overhauled and provided with the bogie is obtained by identifying the model of the bogie, and the daily corresponding operation time of the vehicle to be overhauled is recorded in the operation time recording table, for example, the operation time corresponding to the vehicle to be overhauled is displayed in the operation time recording table as Monday, monday and Friday of every week.

Further, by using the operating time corresponding to the vehicle to be inspected in the operating time recording table, it is possible to obtain the standby time of the vehicle to be inspected, that is, the blank period in step S201, from 2 pm to 5 pm of tuesday, from 2 pm to 5 pm of thursday, from 1 pm to 5 pm of saturday, and from 2 pm to 4 pm of sunday, as the blank period, and from the above, it is possible to determine that there are a plurality of blank periods corresponding to the blank period of the vehicle to be inspected, and to further determine the specific standby and stopped time periods of the vehicle to be inspected in the blank period so as to plan the corresponding inspection time, it is determined that there is an overlap between the blank periods.

And setting the corresponding maintenance time priority of each overlapped time period according to the target proportion, and generating a corresponding maintenance time scheduling table, wherein the target proportion is in direct proportion to the maintenance time priority. For example, it can be seen from the above that the target proportion corresponding to 2 pm to 5 pm on tuesday and thursday is 50%, the target proportion corresponding to 1 pm to 5 pm on tuesday and 2 pm to 4 pm on sunday is 25%, so that the inspection time priority corresponding to the overlapping time period of 2 pm to 5 pm on tuesday and thursday is set to be one level, the inspection time priority corresponding to 1 pm to 5 pm on tuesday and 2 pm to 4 pm on sunday is set to be two levels, the first level inspection time priority is higher than the second level inspection time priority, and the overlapping time periods of 2 pm to 5 pm on tuesday and thursday recorded in the inspection time schedule table are preferentially sent to the relevant inspection personnel.

In practical application, in order to facilitate tracing of the bogie overhaul task items before and after the change, corresponding node change records are generated according to the current bogie overhaul task item and a bogie overhaul change task item corresponding to the bogie overhaul task item.

For example, the maintenance frequency corresponding to the bogie maintenance task item S is 2 weeks and 1 time, the maintenance process standard corresponding to the bogie maintenance task item S is modified and adjusted, the maintenance frequency of the bogie maintenance change task item corresponding to the bogie maintenance task item S, which is obtained as the bogie maintenance task item S, is 1 week and 1 time, and the corresponding node change record is generated by combining the changes: the maintenance frequency of the bogie maintenance task item S is changed into 2-week 1-time maintenance instead of 1-week 1-time maintenance, so that related maintenance personnel can conveniently acquire the change condition of the corresponding maintenance frequency of the bogie maintenance task item S.

If the node change records are multiple, the change times corresponding to the bogie maintenance task items in each node change record are obtained, the more the change times are, the more the fault problems of the bogie components corresponding to the bogie maintenance task items are shown, in order to improve the safety of the bogie components with more fault problems, the bogie maintenance task item with the most change times is further obtained as a preselected maintenance task item, and related maintenance personnel increase the attention of maintenance on the bogie components needing to be detected according to the preselected maintenance task item.

And if the node change record is single, directly acquiring a corresponding bogie maintenance task item in the node change record and a maintenance part corresponding to the bogie maintenance task item, and displaying the maintenance task item and the maintenance part to related maintenance personnel through the station billboard.

Further, if the preselected maintenance task items are multiple, the maintenance data difference corresponding to the preselected maintenance task items is obtained, the preselected maintenance task item with the largest maintenance data difference is selected as the established maintenance task item, the corresponding target component in the vehicle bogie is matched according to the established maintenance task item, the matched target component is recorded to a priority maintenance list corresponding to the vehicle bogie, and the priority maintenance list can be sent to the handheld maintenance terminal of the corresponding maintenance staff through a station signboard or a wireless transmission mode. The larger the overhaul data difference is, the higher the failure rate of the bogie component is, and the purpose of selecting the preselected overhaul task item with the largest overhaul data difference as the established overhaul task item is to improve the attention of related personnel to the bogie component with higher failure rate, namely the target component, and reduce the occurrence of safety accidents in the running of the vehicle.

And if the preselected maintenance task item is single, the bogie maintenance task item corresponding to the preselected maintenance task item and the maintenance part corresponding to the bogie maintenance task item are directly displayed to relevant maintenance personnel through the station watching board.

According to the vehicle bogie overhauling method provided by the embodiment, the target component with the largest number of times of change of the bogie overhauling task items and the largest corresponding overhauling data difference in the vehicle bogie can be obtained according to the priority overhauling list, so that the vehicle bogie component with the serious abnormal problem can be conveniently and timely screened out to be paid attention to by related overhauling personnel in advance, and the overhauling safety of the vehicle bogie component is improved.

In one embodiment of the present invention, as shown in fig. 4, the step S306 of recording the priority service list corresponding to the target component to the vehicle bogie includes the following steps:

s401, if a plurality of target components are available, obtaining damage estimated values corresponding to the target components;

s402, setting a first overhaul ordering rank of each target component according to the damage estimated value, wherein the larger the damage estimated value is, the higher the first overhaul ordering rank corresponding to the target component is;

s403, if the first overhaul ordering names of the target components are the same, acquiring a target failure rate corresponding to the target components;

s404, setting the higher the second overhaul ordering rank of the target component is, the higher the second overhaul ordering rank corresponding to the target component is according to the target fault rate;

s405, combining the first maintenance ranking name and the second maintenance ranking name, and recording a priority maintenance list corresponding to the target component to the vehicle bogie.

In the practical application, in order to improve the safety detection of the vehicle bogie component, it is required to combine damage estimated values of target components in the vehicle bogie to perform comprehensive evaluation, and the damage estimated values can also be a life test of the vehicle bogie component, wherein the larger the damage estimated values corresponding to the vehicle bogie component are, the shorter the corresponding life is, in order to increase the safety maintenance strength of the vehicle bogie component, a corresponding first maintenance ranking rank is set according to the corresponding damage estimated values, the larger the damage estimated values are, the higher the first maintenance ranking rank corresponding to the target component is, and the system preferentially outputs the target component with the highest rank in the first maintenance ranking rank.

Further, if the first overhaul ordering names corresponding to the target components are the same, acquiring a target failure rate corresponding to each target component, wherein the higher the target failure rate is, the worse the stability of the target component in the corresponding vehicle bogie is, the target failure rate corresponding to the target component can be acquired through historical overhaul data, further setting a second overhaul ordering name corresponding to the target component according to the acquired target failure rate, and recording a priority overhaul list corresponding to each target component to the vehicle bogie by combining the acquired first overhaul ordering names and the second overhaul ordering names.

And if the first overhaul sorting ranking orders corresponding to the target components are different, directly sorting the target components according to the first overhaul sorting ranking orders corresponding to the target components, and recording the first overhaul sorting rankings to a priority overhaul list corresponding to the vehicle bogie.

According to the vehicle bogie overhauling method provided by the embodiment, each target component is overhauled in sequence according to the prior overhauling list, so that the target components with serious hidden danger can be overhauled and removed in time, and the safety and overhauling efficiency of each component in the vehicle bogie are improved.

In one embodiment of the present invention, as shown in fig. 5, after generating a corresponding node change record according to a bogie overhaul task item and a bogie overhaul change task item corresponding to the bogie overhaul task item in step S301, the method further includes:

s503, setting feedback priorities corresponding to the variable feedback information according to the support rate, wherein the support rate and the feedback priorities are in a direct proportion relation;

and S504, outputting each piece of variable feedback information according to the feedback priority.

In practical application, corresponding change feedback information is recorded in a node change record corresponding to a bogie maintenance task item, wherein the change feedback information refers to a processing suggestion of a relevant maintenance worker on the bogie maintenance change task item, most of the generation of the bogie maintenance change task item is obtained through system matching comparison and judgment, and the practical experience of the relevant maintenance worker is lacked, so that the maintenance worker can show own viewpoints and suggestions in a change feedback information form according to the bogie maintenance change task item generated by the system, so that the relevant management scheduling worker can use the viewpoints and suggestions for reference, and a corresponding vehicle bogie maintenance plan can be reasonably adjusted.

If the variable feedback information is multiple, in order to screen out more valuable feedback information, the support rate corresponding to each variable feedback information is acquired, the support rate can be expressed by the number of praise comments corresponding to each variable feedback information, the support rate is higher when the number of praise comments is larger, and on the other hand, multiple maintainers holding the same view on the variable feedback information can indicate their own intention in a mode of praise supporting the praise of the comments.

Further, according to the support rate corresponding to the variable feedback information, setting the feedback priority corresponding to each variable feedback information, wherein the support rate is in a direct proportion relation with the feedback priority, immediately outputting each variable feedback information according to the feedback priority, and the higher the support rate is, the higher the corresponding feedback priority is, therefore, when the network communication is in an intermittent fault or delay state, preferentially outputting the variable feedback information with high feedback priority.

According to the vehicle bogie overhauling method provided by the embodiment, when network faults or network delay occur, each piece of variation feedback information can be output according to the feedback priority, so that variation feedback information with high quality can be output preferentially, and relevant workers can analyze and refer the variation feedback information.
