Embodiment Construction

[0027] figure 1 The rail measuring vehicle 1 shown in a simplified manner for recording the track geometry of a track 2 has a running gear 4 movable on the rail 3 and a carriage 5 supported on the running gear 4, and The track measuring vehicle 1 comprises a first measuring base 7 and a second measuring base 11, the first measuring base 7 is designed as a chassis frame 6 and comprises an inertial measurement unit 8 and a position measuring device 9, the second measuring base 11 is Designed to be lowered by means of the first pneumatic drive 10 .

[0028] The second measuring base 11 has a measuring running wheel 12 designed to be arranged on the rail 3 and is connected to the first measuring base 7 via a coupling rod 14 . The coupling rod 14 is rotatably mounted at its upper end 15 on the first measurement base 7 and is connected at its lower end 16 to a first telescopic shaft 17 and a second telescopic shaft 18 respectively. The first telescopic shaft 17 is mounted for rota...

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...
