Research On 25G-type Train Surface Cleaning Robot

Rail transportation industry is an important part of China’s transport sector and plays an important role in the national economy.In recent years,the development of rail transport business is rapid,but the development of corresponding cleaning equipment for rail vehicles is delayed.Although some cleaning equipments for rail vehicles exist in the domestic market,the limitations are significant.Most of the cleaning work of rail vehicles by is still done manually at present,which cause poor working environment,high strength,low efficiency and high cost.The article takes the Beijing Railway Station and Qingdao Railway Station as the examples of the cleaning work of rail vehicles to conduct an investigation.The track setting conditions of railway station depot and water supply system are analyzed.The reasons why cleaning equipments on the market at present can not be widely used are obtained.On this basis,a new type of rail vehicle self-cleaning robot is designed.The robot’s mechanical structure and operating principles are studied and the procedure of the cleaning equipment and movement equipment are designed in detail.The mechanism model and simulation model are created in Solidworks 2008.In order to ensure constant pressure of the rolling brush against vehicle cortical during the work,the spring dodge device is adopted and an optimal design method is provided in rolling brush design.In cleaner spray and water flushing system,The pressure loss and flow of the wash detergent and water spray system are calculated based on the experimental analysis.The driving resistance of the robot was calculated in this article.On the basis of the design of mechanical structure,control system of cleaning robot is designed,so the robot automation and intelligence are improved.The automatic tracking ability of the robot is achieved.STC89C52RC microcomputer is adopted as the controller for the control system.Combining with the moving characteristics of all agencies,the corresponding driver chips are selected and the peripheral circuit is designed.The circuit diagram of control system is drawn in Protel 2004 and the Keil software is adopted to write the main program and each subroutine.In this paper,the implementation methods of the cleaning rolling brush avoid institutions and the robot follow mark function are discussed.The pressure fluctuation between rolling brush and vehicle cortical are settled,which make the robot automatically run.This technique could guarantee the cleaning effect,commendably meeting the application aim,it probably fills in the gaps of mobile rail vehicle cortical cleaning robot in our country.
