Embodiment Construction

[0049] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0050] In the process of sequentially transporting the rails from the rail conveying vehicle to the rail pushing vehicle, the roller recovery vehicle and the rail tractor, there are multiple transfers of different traction devices. During these transfers, the rail clamps are often fixed, and the rail clamps The position may be shifted due to the position deviation of the construction vehicle itself. At the same time, the manual operation of grabbing rails, aligning rails and recycling rollers has a greater safety risk. In order to solve the above problems, such as figure 1As shown, the present invention proposes an intelligent control method for the laying process of ballastless track rails. The main control system controls...

Abstract

The invention discloses an intelligent control method for a ballastless track steel rail laying process, and particularly relates to the field of track laying. A visual sensor and a position sensor are arranged at each steel rail connecting piece, real-time position coordinates of the steel rail are acquired by utilizing the visual image; a manipulator is controlled to grab the steel rail according to the real-time position coordinates of the steel rail; the moving track of the steel rail is calibrated through the guide frame and the bracket according to the real-time visual information, and when the steel rail is guided out from the transition device, the center line of the ballast bed can be accurately aligned; meanwhile, the movement of the manipulator is controlled by utilizing the steel rail real-time coordinates obtained by the visual images so that when the steel rail is grabbed and fixed by the manipulator, the grabbed position coordinates can be kept consistent with the calibrated position coordinates, and the laying accuracy of the steel rail is not influenced by the position deviation of the construction operation 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] ...
