Problems solved by technology

At present, the railway engineering department generally uses observation piles buried on both sides of the track to measure the creepage of the rails, marking the rails, and using artificial strings to measure the creepage of the rails. This method has defects such as poor accuracy and low efficiency.
For time-critical railway skylights, the requirements cannot be met

Abstract

The invention relates to the field of railways, and discloses a steel-rail detection device. The steel-rail detection device comprises a first observation pile, a distance measuring device and a control device, wherein the first observation pile is mounted a preset distance away from one side of a steel rail; the distance measuring device is used for measuring a present longitudinal distance between the first observation pile and one side of the steel rail; the control device is used for confirming the crawling amount according to the difference between an initial longitudinal distance between the first observation pile and one side of the steel rail and a present longitudinal distance between the first observation pile and one side of the steel rail.

Description

technical field [0001] The invention relates to the field of railways, in particular to a rail detection device. Background technique [0002] When the train is running on the track, due to the rolling, traction, braking of the wheels and the temperature stress of the current seamless line, the rail will be displaced in the longitudinal direction, that is, the rail will crawl. Excessive crawling of the rails will cause the rails to fail to generate large tensile and compressive stresses. In severe cases, rail breakage or rail expansion accidents may occur, affecting driving safety. [0003] The railway engineering department must regularly inspect the crawling amount of the rails. At present, the railway engineering department generally uses observation piles buried on both sides of the track to measure the creepage of the rails, marking the rails, and using artificial strings to measure the creepage of the rails. This method has defects such as poor accuracy and low effici...
