US 12,157,978 B2 · Method and device for stabilizing a track

Abstract

A method for stabilizing a track having sleepers supported on a track ballast and rails secured to the sleepers, includes using a stabilizing unit which is connected to a machine frame that can be moved on the rails and has a vibration exciter and rollers that can roll on the rails. The vibration exciter generates in particular horizontal vibrations which run transversely to the track longitudinal direction. The course of a force exerted onto the track by the stabilizing unit is recorded over a vibration path during a vibration cycle by sensors. At least one parameter is derived from the course by an evaluation device and is used to evaluate the stabilizing procedure and/or the quality of the track ballast. A device for implementing the method is also provided.

Dependent claims

A method for stabilizing a track having sleepers supported on track ballast and rails fastened on the sleepers, the method comprising:

providing a machine frame being mobile on the rails;
connecting a stabilizing unit to the machine frame, the stabilizing unit including a vibration exciter and rollers configured to roll on the rails;
using the vibration exciter to generate vibrations running transversely to a longitudinal direction of the track;
using sensors to record a course of a force acting from the stabilizing unit on the track over an oscillation path during a vibration cycle;
and
using an evaluation unit to derive at least one parameter from the course and to evaluate at least one of a stabilizing procedure or a quality of the track ballast.
