Embodiment 1

[0066] Embodiment 1: The present invention provides a precision detection system suitable for ballastless track slabs, including at least four centering screw hole adapters 1, at least four precision spherical prisms 2, at least one meteorological sensor 3, and at least one bolt pile A detection sleeve 4, at least one total station 5, at least one set of track plate detection software 6, at least one set of post-processing analysis software 7 and at least one computer 8.

[0067] Assemble a self-centering screw adapter 1 and a precision spherical prism 2 and place it on the embedded sleeve of the track plate to form an observation point, or combine a centering screw adapter 1, a precision spherical prism 2 and a bolt After the pile detection sleeve 4 is assembled together, it is placed on the bolt pile 9 protruding from the steel mold hole of the track plate to form an observation point. The track plate detection software 6 is installed on the total station 5, and the post-pro...

Embodiment 2

[0083] Embodiment 2: on the basis of embodiment 1, carry out further improvement. The total station 5 used in the present invention is Leica TCA1800, which has standard functions such as orientation and elevation transfer, resection, opposite side measurement and stakeout, etc. After adding software, it can also realize hanging height measurement, hidden point measurement, area measurement, multi-measurement Return direction observation, traverse measurement, local resection function. The total station realizes automatic target search and automatic target aiming, and its angle measurement accuracy is 0.52 in one round direction standard deviation, and its distance measurement accuracy is 1mm+1ppm. Improve the measurement accuracy and automation level, improve labor productivity.

[0084] In this embodiment, the Leica DNA03 electronic precision level is also used to carry out random inspection and comparison for the coplanarity accuracy of the Leica TCA1800 total station. The...

Abstract

The invention relates to a precision detection method applicable to a slab ballastless track plate. The precision detection system comprises a self-centering screw hole adapter, a precision spherical prism, a meteorological sensor, a bolt pile detecting sleeve, a total station, track plate detecting software, post-processing analysis software and a computer. By using the detection system and method, the detection time of each track plate is shortened to 6-8 minutes, and the detection precision and the detection speed of the track plate are increased.

Description

technical field [0001] The invention relates to a precision detection method suitable for ballastless track slabs. Background technique [0002] Ballastless track has the advantages of strong integrity, good stability, durability, small track deformation, and slow deformation accumulation, which is beneficial to high-speed driving and has been widely used in many countries in the world. Among the world's railway ballastless track structures, the German double-block and Borg slab ballastless track structures and the Japanese unit slab ballastless track structure are represented. In Germany, Berlin-Hannover was built and put into operation in 1998, with a running speed of 300km / h, and Japan's Shinkansen, which uses a slab ballastless track structure, runs at a speed of 250km / h. [0003] my country's railways will adjust the national railway operating mileage planning target from 100,000 kilometers to more than 120,000 kilometers in 2020, of which the passenger dedicated l...
