Development and application of intelligent trackless track laying transportation equipment for urban rail transit projects

Abstract

This article introduces an intelligent trackless laying system for urban rail transit projects. The track laying system mainly consists of mechanical systems, intelligent control systems, deflection correction systems, obstacle avoidance systems, electrical systems, and hydraulic systems. The overall equipment can achieve free span change, lifting and height adjustment, suspension angle adjustment, and trackless movement in circular, horseshoe shaped, rectangular and other tunnels. The lifting platform also has functions such as lifting, traversing, and turning, and can lift various components such as track bed boards, track panels, ash hoppers, and concrete mixing tanks. Under electrical and hydraulic control, the equipment having strong adaptability, and multifunctional integration can achieve stepless speed change and wireless remote control, and also has automatic deviation alarm, obstacle alarm and speed reduction, and Fault self-diagnosis function. The developed equipment has improved the overall construction efficiency of track laying operations, saved project costs, and also solved the safety hazards caused by traditional construction methods.
