System and method for monitoring and evaluating service state of steel spring of floating slab ballast bed

Abstract

The embodiment of the invention relates to the technical field of urban rail transit, and provides a system and method for monitoring and evaluating the service state of a steel spring of a floating slab ballast bed. The system provided by the embodiment of the invention for monitoring and evaluating the service state of the steel spring of the floating slab ballast bed comprises a pressure sensor, a displacement sensor and a monitoring device, wherein the pressure sensor is used for performing pressure detection on a steel spring arranged above the pressure sensor; the top end of the displacement sensor is flush with the top end of the steel spring, and the displacement sensor is used for detecting the displacement of the steel spring; and the monitoring device is electrically connected with the pressure sensor and the displacement sensor so as to process, calculate and analyze the received pressure data signals and displacement data signals, and thus the service state of the steel spring is evaluated. According to the system provided by the embodiment of the invention for monitoring and evaluating the service state of the steel spring of the floating slab ballast bed, whether theservice state of the steel spring is good or not is judged by means of the vibration signal generated when a train passes by the measurement section during operation. Manual guard is not needed, andthe automation degree is high.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a system and method for monitoring and evaluating the service state of steel springs on floating slab track beds. Background technique [0002] In recent years, with the construction of cities, rail transit has developed rapidly. In order to reduce the impact of urban rail transit vibration on residents and surrounding buildings along the track, steel spring floating plate vibration reduction measures are widely used in urban rail transit lines. Because of its good vibration reduction effect, it is used in important vibration reduction environments. As a vibration reduction consumable, steel springs need to be checked and replaced regularly. [0003] According to the regulations of relevant local technical standards, the steel spring components are mainly inspected on a regular basis, the inspection form is spot check, and the method is to take out the steel spring fo...

AI Technical Summary

Problems solved by technology

Regular manual inspections mainly rely on the subjective judgment of technicians to confirm whether the vibration reduction measures are good, and cannot play the role of quantitative analysis and early warning. At the same time, there will be a certain probability of failure in random inspections, which will bring safety hazards to train operation.
