Servo centering device of rail flaw detection robot

Abstract

The invention relates to a servo centering device of a rail flaw detection robot. The servo centering device of the rail flaw detection robot comprises at least one detection wheel and further comprises an integrated support, wherein the detection wheel is installed on the integrated support and is installed on a flaw detection trolley used for rail flaw detection operation, an adjusting system is formed on the integrated support, and when the flaw detection trolley conducts flaw detection operation, the adjusting system adjusts the operation state of the detection wheel in the horizontal direction, the vertical direction and the running direction of the detection wheel, so that the detection wheel and the top surface of a rail are always kept in good coupling to accurate receive, transmit flaw detection signals and avoid report mistakes and report failure.

Description

Technical field [0001] The invention relates to a steel rail flaw detection robot servo centering device, in particular to a steel rail flaw detection robot servo centering device suitable for ultrasonic detection of railway track damage. Background technique [0002] As the main artery of the national economy, the railway is one of the most important infrastructures in the country, and it is also the most popular mode of transportation related to each of our citizens. In our country, with the increase of train speed and axle load, coupled with the thermal expansion and contraction of metal due to environmental reasons, the speed of rail damage has also increased accordingly, resulting in a trend of shortening the inspection cycle. Rail inspection work is to ensure the safety of railway running Important measures. [0003] The inspection of rails in my country mainly adopts ultrasonic testing methods, mainly using large-scale flaw detectors and small flaw detectors to inspect the ...

Problems solved by technology

However, such a flaw detection trolley often cannot be well coupled between the detection wheel and the rail surface because the trolley shakes and shakes due to the instability of the force during the human push, resulting in a certain impact on the sending and receiving of signals. During the implementation process, the detection wheel installed on the trolley is easy to deviate from the center line of operation, which often causes missed or false alarms, which also causes a lot of interference to the flaw detection operation

When it is necessary to replace the detection wheel of the trolley or other working parts, the replacement action will inevitably affect the coupling effect between the detection wheel and the top surface of the rail, and it takes a lot of time and manpower to make adjustments

In rainy and snowy weather, the detection wheel will easily have poor coupling with the top surface of the track due to environmental factors or even derail
