The Design And Manufacture Of Automatic Uncoupling Robot Model

China's railway industry is in a period of rapid development,accompanied by the gradually networking of high-speed railways and a substantial increase in the railway freight volume.Marshalling station is an important node of the railway freight network,and its efficiency can directly affect the entire railway freight network.However,marshalling hump lines are still using the traditional artificial uncoupling model to decompose rail trains,which greatly affects the working efficiency of marshalling stations.Given this,it may be desirable to design an automatic uncoupling robot that can assist or replace workers in completing the dangerous and complex uncoupling operations,thereby effectively reducing rework waste and improving marshalling stations efficiency.In view of the types of railway wagons and the characteristics of couplers used in China,as well as the uncoupling workflows,an automatic-uncoupling-robot solution available for the hump lines was provided in this article.Furthermore,an automatic uncoupling model system comprising an automatic-uncoupling-robot model,a train model and a coupler model was established based on the solution to study and demonstrate the uncoupling process.The automatic uncoupling robot model,equipped with a DC motor,a stepper motor,a steering gear and other drive apparatuses,implemented the uncoupling work on the basis of signals returned from feedback devices such as diffuse laser sensor,ultrasonic sensors,infrared sensors and the like.This article relates to an overall design of the automatic uncoupling robot,a design and a production process of the automatic uncoupling robot model and the train model,a design of the model control system circuit board,the preparation of the model control software,etc.The model production mainly included the design and production of the model bearing mechanism and the automatic uncoupling robot actuator.The design of the control system chiefly involved the selection of the master chip and the driving chip,the design of the control circuit and the fabrication of the PCB.The programs,written in C language,could control the uncoupling robot work and realize the communication between the uncoupling robot,the monitoring computer and the train model.The research results herein can provide a reference for automatic uncoupling robot design.The automatic uncoupling model system in its entirety can be used in classroom demonstration or toy development.
