the track measuring instrument can be used not only in the early stage of construction, but also in the later stage of railway maintenance work in the public works section of the road bureau. the track measuring instrument is suitable for various slab types (crtsi, crtsii, crtsiii type track fine adjustment and double fast type) ballastless track construction, track slab adjustment and operation management after opening to traffic. the southern high-speed railway track measuring instrument has been successfully used in the construction of high-speed railways such as chengguan, harbin, beijing-shanghai, shanghai-hangzhou, shanghai-nanjing, jingshi, shiwu, beijing-shanghai, guangzhou-zhuhai, and hainan east ring.
the geometric state detection system, also known as the track inspection trolley, is a convenient tool for detecting static inspection irregularities. it adopts advanced detection and data processing equipment such as electrical measurement sensors and special portable computers. it can detect height, level, twist, track, etc. track irregularity parameter. the rail inspection trolley can not only be used in the preliminary engineering construction, but also can complete the railway maintenance work in the public works section of the road bureau in the later period. the technical parameters of the track inspection trolley must reach the following levels. the southern high-speed railway track measuring instrument, also known as the track inspection trolley, is a convenient tool for static detection of unevenness. it can detect track irregularity parameters such as height, level, twist, and track. the accuracy of the gauge sensor is ±0.3mm, the accuracy of the level sensor is ±0.5mm, and the accuracy of horizontal position and elevation measurement is ±1mm.
at present, the aca616t full temperature compensation high-precision inclinometer produced by our company has successfully passed the technical appraisal and approval of the ministry of railways on the customer's gauge inspection trolley. the raw sensor also has the accuracy test report of the national metrology institute, and the small angle accuracy can reach 0.002 degrees.
