Abstract: The fine adjustment operation of traditional CTRSⅢ ballastless track slab is mainly manual with high labor intensity and high construction cost, so it is difficult to ensure the quality and efficiency of adjustment operation. Using the technologies of system integration, numerical control and algorithm analysis, the intelligent fast fine adjustment equipment for CTRSⅢ ballastless track slab is developed, which is maneuverable and simple to operate. Via the data interfaces with the total-station instrument and the ballastless track slab construction design software, this equipment can conduct data measurement and transfer and calculate the adjustment amount of the track slab automatically and control the automatic mechanical adjustment of the track slab in an intelligent manner.The test shows that the equipment requires only one person to complete the fine adjustment of the track slab quickly, greatly saving manpower and observably improving the efficiency and quality of the fine adjustment of the track slab. However, the low adjustment efficiency in multiple directions still needs further research and solution.
