This paper features the intelligent fine-tuning system of CRTS I double-block ballast-less track,a technology that integrates automatic measurement subsystem,intelligent control subsystem,intelligent finetuning execution subsystem and computer data processing. Electrical motors are installed on the fine-tuning machine to drive the robot moving along the rail;electron-hydraulic rod is embedded into the bottom of the fine-tuning machine,and prism rod and precision prism are attached at both ends thereof to accurately locate the robot,and to measure the gauge and gauge change rate of the rails;robotic arms ( with servomotor and universal adapter) are mounted on the fine-tuning machine,under the command of industrial control system software,to give the robot the power to automatically lock the screws of rail row support frame,and to automatically adjust the rail direction and elevation of the rail row;through the design of the inner and outer nested rail support frame,the fine-tuning robot can adjust the rail direction and vertical direction simultaneously without affecting each other;while through wireless transmission technology,real-time data transmission among total station,fine-tuning robot and backstage management system is solved. The efficient and smart auto fine-tuning in ballast-less track construction is thus realized. The operation efficiency of the fine-tuning robot has been proved onsite to be 300 m per day,which is more than twice that of the traditional method,meanwhile the measurement accuracy is more reliable,not being affected by human factors.
