Rapid detection device and detection method for track plate deformation

Abstract

The invention discloses a rapid detection device and a detection method for track plate deformation. The device comprises a beam, a support sleeve, a telescopic leg, a tension spring, a fixing bolt, abracket, and a PSD laser system, wherein the telescopic leg is located in the support sleeve, and the lower end of the telescopic leg is exposed outside the support sleeve; the upper end of the support sleeve is fixedly connected with the lower end surface of the beam through the fixing bolt; the tension spring is arranged between the beam and the upper end of the telescopic leg; the upper end ofthe beam is provided with the bracket; the bracket is provided with the PSD laser system; the PSD laser system is wirelessly connected with a detection system. Compared with the prior art, the rapiddetection device and the detection method for the track plate deformation have the advantages that deformation detection is performed on a CRTS III type track plate, the accuracy is improved and the requirements on the field environment, personnel and equipment are reduced compared with the conventional on-site detection; the measurement method is rapider, more accurate and more cost effective than the existing measurement method.

Description

technical field [0001] The invention relates to the application field of sensor technology in the construction of ballastless track of high-speed railway, in particular to a rapid detection device and detection method for track plate deformation. Background technique [0002] CRTSⅢ type slab ballastless track is a ballastless track with completely independent intellectual property rights based on the introduction, absorption and re-innovation in my country. It has the characteristics of high precision, two-way prestressing, simple process, and factory production. However, like the foreign Borg slab (called CRTS II track slab in China), due to the long and thin concrete structure, the track slab is prone to warping and deformation during transportation, storage and hoisting due to the influence of the concrete's own stress and gravity. When the deformation value is greater than the project expectation, it will affect the construction quality of the track. Therefore, detecting...

Problems solved by technology

Due to the high accuracy requirements of track slab detection, two methods are currently used to control the accuracy of CRTS III track slabs. One is three-dimensional laser scanning; the other is total station with frame measurement. The above two methods are generally expensive. , numerous procedures, complicated technology, and great impact on the environment, which requires careful implementation by a professional team

In particular, the total station combined with the frame measurement method not only occupies special equipment, but also needs to use the total station to freely build a station when testing CRTS III track slabs. The complex construction site environment and personnel are more difficult for CRTS III track slab testing. And it takes a long time, resulting in low accuracy of the test results, and the workload of the testers is also very complicated
