Research on Positioning Improvement Technology for Sleeve of Turnout Sleeper in Long Line Production
Turnout sleeper is an important part of high-speed railway track structure.In order to ensure the stress state of railway fastener system in the turnout area,the accuracy of casing embedded position is very high.In order to solve the problem of high reject rate caused by poor positioning of type Ⅲ sleeve in the production of turnout sleepers by long line pedestal method,this paper puts forward some optimization measures after extensive experiments and practical research,such as fixing the screw positioning base to solve the problem of vertical positioning offset and improving the automatic detection of the nail hole rangefinder to increase the accuracy to solve the problem of horizontal positioning offset.These measures not only guarantee the positioning accuracy of type Ⅲ sleeve,improve the quality of turnout sleepers,but also meet the requirements of long line pedestal method production turnover.
