The Design Of The High-speed Railway Turnout Comprehensive Inspection Instrument Which Is Based On ZD Management

Turnout is the major infrastructure equipment of railway construction，integrated systems of engineering and electrical integration， and one of the keyequipments of limiting the train’s running speed. A country’s railway developmentlevel is concentrated reflected by the technical level of turnout is. At present，although some track inspection instruments can measure a small part of turnoutpoint， because of the items of the high-speed railway turnout inspection are so manyand difficult， the high-speed railway turnout has yet no an integrated measurementequipment to provide a comprehensive measure， record and evaluation platformsand system， which has seriously affected the development of China’s high-speedrailway.According to the analysis of new detection technology， based on the actualneeds of the high-speed rail turnout points detection， under the guidance of ZDManagement thinking design and develop a high-speed railway turnoutcomprehensive inspection instrument for the detection of high-speed railway turnout.Thesis describes detailly the work of project demonstrate stage， product design anddevelop stage， prototypes confirmed and pre-production stage， and the rest of thevarious stages， which is under the guidance of "zero defect" management thinking tocarry out the new product， complete the whole process from product research，overall design， detailed design， pre-production prototype and experiment， andultimately get the high-speed railway turnout comprehensive inspection instrumentand carry out the corresponding prototype measurement experiments.The high-speed railway turnout comprehensive inspection instrument withintegrated management system that can measure and evaluate integrated high-speedrail turnouts， solve the actual measurement and evaluation require a lot of humanand a variety of inspection equipments， cumbersome procedures of separate pointand multi-step operation in the past， can largely reduce the intensity and number ofthe staff and reduce the number of railway equipments. The instrument uses a new "工" structure， not only achieve the detection of many points for high-speed rail turnout， but also achieve the direct measurement of track middline of continuouspoint and fixed-point and the measurement of true gauge and the true level. Thus，the high-speed railway turnout integrated tester has a strong practical applicationprospects are very optimistic， can have a greater social and economic benefits.
