Abstract

The invention relates to a track-measuring vehicle (1) for recording a track geometry of a track (2), having a vehicle frame (5) which can move on two rails (3) of a track and has rail bogies (4), andhaving a first measuring base (7) on which an inertial measuring unit (8), and at least one contactless position-measuring device (9) for determining the position with respect to each rail (3), are arranged. There is provision here that a lowerable second measuring base (11) is arranged, which second measuring base (11) comprises measuring running wheels (12), which can be set down on the rails (3), and is connected to the first measuring base (7) via compensation-measuring devices (20, 22).

Description

technical field [0001] The invention relates to a track measuring vehicle for recording the track geometry of a track, said track vehicle comprising a carriage with an on-rail running gear and movable on two rails of the track, and comprising a first measuring base, An inertial measurement unit and at least one non-contact position measuring device for determining the position relative to each rail are arranged on the first measurement base. The invention also relates to a method for operating such a rail survey vehicle. Background technique [0002] In order to maintain the permanent lines of the track, regular controls are required. For this purpose, the track is regularly traversed by a track measuring device in the form of a track measuring vehicle, which records the track geometry for subsequent evaluation of the track geometry. Since track geometry directly affects the driving dynamics of vehicles traveling on rails, accurate measurements are critical for assessing r...
