Turnout rail creeping amount monitoring device

Abstract

The invention provides a turnout rail creeping amount monitoring device. Turnout rails comprise turnout stock rails and turnout switch rails, two creeping amount detection assemblies are installed on the same cross section of the turnout rails, the creeping amount detection assemblies comprise magnetic metal fixedly installed on the turnout switch rails and electrical vortex sensors fixedly installed on the turnout stock rails, and the lateral surfaces, close to the turnout stock rails, of the magnetic metal serve as creeping amount measuring reference surfaces. The turnout rail creeping amount monitoring device further comprises a collection device and a processor, and the processor is in communication connection with a remote control terminal through a communication interface. The turnout rail creeping amount monitoring device has the advantages that the device is fixed to the rail bottoms by using cold end clamping units and elastic clamping units, and no holes need to be drilled in the rails for installation; the creeping reference surfaces move along with the switch rails, the movement space of the creeping reference surfaces is located in existing space between the rail bottoms and the ground, and track beds do not need to be damaged; measurement errors are small.

Description

technical field [0001] The invention relates to the field of rail traffic safety, in particular to a device for monitoring the crawling amount of a turnout rail. Background technique [0002] As one of the important equipment for driving, the reliability and stability of the turnout is very important for the safety and smoothness of driving. As the moving parts of the turnout, the point rail and the core rail play an important role in changing the direction of the train. Its operating parameters play an important role in the safe operation of the turnout. [0003] The creepage of the turnout rail is divided into the creepage of the point rail and the creepage of the center rail. The creepage of the switch rail refers to the longitudinal displacement of the switch point rail relative to the basic rail. The core rail creepage refers to the longitudinal displacement of the switch core rail relative to the wing rail. The creeping amount of the point rail or the core rail is ...

AI Technical Summary

Problems solved by technology

[0005] Manually obtaining the crawling amount through the reference mark points has the following disadvantages: the train passing speed is increased or the operation interval is shortened so that the maintenance personnel can only go to the skylight point for inspection and maintenance. The crawling amount of the section cannot be obtained; due to the constraints of the on-site working environment, the accuracy of manually measuring the creeping amount through reference mark points is low; it is impossible to obtain the corresponding relationship curve between temperature change and creeping amount change. Mastering the corresponding relationship curve can adjust the turnout in advance according to the weather forecast To the ideal working condition, to avoid the event that the turnout failure causes the train to stop running when the temperature difference changes greatly
