FTLong-wave Smoothness Measuring Instrument for Track
1. Measuring Principle and Application
The long-wave smoothness measuring instrument for track is a high-precision instrument that measures based on photoelectric image principle, and can accurately measure various geometric parameters of the track. This instrument integrates optics, mechanics, electronics and wireless network, uses special light source and CCD image sensor to conduct high-precision detection on the geometric shape of railway track, and enables the direct digital display of parameters such as track level and alignment. It provides reliable measurement data for track equipment maintenance, solves the problems of poor measurement accuracy and low efficiency of existing methods, and meets the night operation requirements of "window maintenance" for track maintenance and improves the quality of night operations.
This instrument can measure the level and alignment parameters within the 200m long-wave range. It provides reliable and effective data for track fine adjustment and maintenance, and is a powerful supplement to the absolute measurement of high-speed railway CPIII.
1. Conventional track geometric parameter detection and construction operation guidance for railway track maintenance departments.
2. Recheck of track maintenance results after track line overhaul.
3. Disease detection after alarm of track dynamic inspection vehicle.
4. High-precision measurement of track lines on high-speed passenger dedicated lines.
II. System Composition and Measuring Principle
The system consists of a launching vehicle, a measuring vehicle and a feedback vehicle. The launching vehicle and the feedback vehicle are fixed at both ends of the section to be measured. The launching vehicle emits two collimated laser beams in the transverse and longitudinal directions, and forms a reference with the centering of the feedback vehicle. The measuring vehicle is pushed on the section to be measured, and measures the displacement of the collimated laser beam through a high-precision CCD, and converts the displacement into various geometric parameters. The feedback vehicle monitors the jitter of the collimated laser in real time, and transmits the jitter amount to the measuring vehicle in time for correction, eliminating the impact of laser jitter on the measurement results.
