Research on Automatic Measurement Technology of Front Track Deviation of Tamping Machine

This paper presented a scheme of automatic measurement technology for front track deviation of tamping machine for temporary maintenance work.The measurement system adopts the measurement principle of inertial navigation system and the intelligent and integrated measurement and control technology,which is carried on the tamping machine to enter and leave the working area synchronously.The measurement system was used to measure the track geometric parameters and process the data of the construction section before and after the tamping machine operation to guide the fine operation of the tamping machine,ensure the synchronization of tamping and measurement,and effectively solve the problems of frequent manual access,low efficiency and high labor intensity existing in the traditional mode.The test line was selected for rapid and multiple measurements,the track geometric parameters,such as track direction,height,track gauge,superelevation,elevation,etc.,will be calculated and obtained automatically,and the repeatability deviation of each parameter could meet the index requirements.
