An Automatic Diagraph For The Parameter Of The Wheelset

Under the circumstances of railroad high speed and haul load, it is particularly important to improve the ability of railway transportation, to realize the modernization of railway transportation and to guarantee the produce safety of railway transportation. It is not impossible to improve the vehicle moving speed and moving safety if there were no best wheels in function to ensure the safety. Wheels parameter examining is placed in key position in wheels overhaul, and it is an important means to ensure the quality of wheels overhaul. Traditional examining method mainly depends on artificial operation and there are more man-made errors in data judgment , so effects the accuracy and reliability of the examination result and effects the vehicle's safety directly .Therefore, the current examining methods are needed to be computerized and automated urgently to remove the influence of testing of the artificial factor in the process of test and ensure the vehicle's safety with advanced facilities, so a new kind of wheels parameter full-automatic machine is developed to solve this problem in this text.The wheels parameter full-automatic machine that is discussed in the text ,it is a set of modern intellectual test system, is suitable to the examination of all sorts of wagon wheels, and it also can carry out the full automatic measures to more than 10 wheels geometric parameters, the rim thickness, the wearing and tearing of treading area, etc. The gauging-machine consists of main engine, hydraulic system, communications system of data collection, controlling test system, etc. The machine changes the method of traditional artificial measuring wheels and fulfils the change of control "from man-control to machine control" of wheels manufacture and examining quality, automatic measures of wheels sizes, avoiding artificial misjudgment, wave motion, mis-examination, wrong examination, etc. The gauging data should be accurate, we should fulfill automatic monitoring of testing quality and avoid the mistakes of data, causing unnecessary economic losses.It can ensure testing quality that the wheels parameter full-automatic gauging machine. The development and application of the machine have active significance totechnical promotion of railway transportation equipment, artifice modernization of test, safety of train transportation under the new situation.
