Description

Intelligent turning system of non-falling wheel lathe and operation method thereof

Technical Field

The invention relates to the field of intelligent control of a wheel lathe, in particular to an intelligent turning system of the wheel lathe and an operation method thereof.

Background

The high-speed rail as a gold name card in the high-end manufacturing industry in China becomes one of the most convenient transportation tools for people to travel in China, has the characteristics of highest operation speed, longest operation mileage, more attached motor train units, long single-travel distance, high running density and the like, and greatly increases the daily maintenance requirement of the motor train units along with the year-by-year increase of the number of motor train units planned to run in China. The turning repair without wheel dropping of the motor train unit is used as an important component part for daily maintenance of the motor train unit and plays a key role in the running quality of the motor train unit. When a motor train unit runs for a certain kilometer, the tread of a wheel is worn to change the profile of the tread, or when the wheel of the motor train unit slips and is rolled by foreign matters, the tread of the wheel is scratched or damaged, or even part of the material is peeled off; when the situation occurs, the motor train unit needs to be pulled above the fixed wheel lathe to carry out turning repair on the wheel pair, and the contour size and the surface quality of the wheel tread of the motor train unit are recovered; if the turning repair is not timely, the conditions of instability of a bogie, serious shaking of a train body, falling and damage of parts and the like during running of the motor train unit are likely to be caused, and the running safety of the motor train unit is affected.

The existing turning and repairing operation mode and the control measure without wheel dropping are as follows:

(1) an operator goes to a dispatching room of a bullet train section to receive a turning and repairing operation plan of a paper edition on the day, manually pushes a brake to open the non-falling wheel lathe, manually carries the standard wheel pair to the non-falling wheel lathe, manually clamps the wheel pair and verifies the lathe.

(2) And manually inputting relevant information and operating the wheel lathe to adjust the wheel distance to adapt to the wheel distance of the motor train unit according to the wheel distance of the motor train unit to be turned, and manually carrying and replacing the corresponding top block and the pressing claw according to the motor train unit to be turned.

(3) An operator manually operates the tractor to be connected with the motor train unit to be turned and pulls the motor train unit to the upper part of the underfloor wheel lathe, the operator manually and visually operates the traction motor train unit to enable the wheel pair to be turned to be aligned with the underfloor wheel lathe, and the operator manually operates the machine tool to clamp the axle box of the wheel pair to be turned.

(4) An operator tears a section of reflective film to be adhered on the outer side surface of the rim, and operates the wheel-free lathe to start a measuring and processing program; operating personnel need continuously to monitor the cutter cutting condition by visual observation in the course of working to the winding iron fillings are colluded in real time manually, and the back is accomplished in the processing, and operating personnel manually tears the reflective membrane of removing the rim lateral surface, and the condition after the visual inspection wheel set tread processing, and the relevant machining dimension data of record.

(5) Manually loosening the machined wheel pair by an operator, repeating the operation, and finishing machining all the wheel pairs needing turning of the motor train unit to be turned; and printing related processing data, manually signing and archiving.

The existing turning operation mode is based on traditional tools and equipment and mainly adopts manual operation of operators, and the following defects generally exist:

(1) the existing turning operation mode has too many manual participation links, is greatly influenced by human interference factors, and cannot effectively ensure the operation quality, and certain manual operation links are easy to cause accidents and cause economic loss when operation personnel have operation errors.

(3) The number of operators is more, and the operation efficiency is lower. Due to the lack of effective automatic and intelligent means, the motor train unit can only be stared at and checked by manpower, on one hand, more inspectors are invested, on the other hand, a large amount of time is occupied, the whole operation time is forced to be prolonged, and the line rate of the motor train unit is reduced.

(4) The operation result can not be quantized and informationized, and the historical operation data can not be formed to effectively support the promotion management. Due to the fact that electronic documents are difficult to form, quantitative data are unavailable, an information system cannot be accessed, support for operation data analysis is very limited, and trend assessment and problem prevention are difficult to conduct on the whole service life of the wheel set based on big data.

In summary, as the holding capacity of the motor train unit is increased more and more, the wheel set turning workload is increased dramatically, the existing turning operation mode cannot meet the demand, and in order to reduce the investment of labor cost, simplify the wheel set turning process, reduce the risk of equipment failure and economic loss caused by manual misoperation, shorten the wheel set turning time of the motor train unit, thereby improving the online rate of the motor train unit, a more intelligent turning control system of the wheel set is needed to be developed urgently.
