An intelligent control method for ballastless track rail laying process

Abstract

The invention discloses an intelligent control method for the laying process of ballastless track rails, and specifically relates to the field of track laying. The present invention obtains the real-time position coordinates of the rails by using visual images through the visual sensor and the position sensor arranged at each rail transfer part, and controls the manipulator to grab the rails according to the real-time position coordinates of the rails, and passes the guide frame and the bracket according to the real-time visual information Calibrate the running trajectory of the rail so that the rail can be accurately aligned with the centerline of the ballast bed when it is exported from the transition device. The position coordinates after grabbing are consistent with the position coordinates after calibration to ensure that the accuracy of rail laying is not affected by the position deviation of the construction vehicle.

Description

technical field [0001] The invention relates to the field of track laying, in particular to an intelligent control method for the laying process of ballastless track rails. Background technique [0002] Ballastless track is a track structure type composed of concrete or asphalt mortar instead of loose ballast bed. It has the characteristics of high track stability, good rigidity uniformity, strong structural durability and significantly reduced maintenance workload. For high-speed railways Compared with the traditional ballasted track, it has better adaptability, but its construction requirements are relatively high. The track must be built on a solid, stable, non-deformed or limited deformation foundation. Once the foundation deformation sinks beyond the adjustable range of the track or It will be very difficult to repair and rectify the damage of the track structure. At the same time, due to its integrated structure, its vibration and noise are relatively large. [0003] ...
