Abstract
A machine for cleaning a ballast bed has, in front of a take-up device relative to a working direction, a first signal receiver—suitable for position determination in a global navigational satellite system—for scanning an actual track position. A second signal receiver connected to the machine for scanning a new track position created by laying down the raised track onto the re-applied ballast bed is arranged downstream. Both signal receivers are associated with a control device designed to act on the drives that displace a track-lifting device relative to the machine frame.
Claims8
A machine for maintenance of a track, the machine comprising:
- a machine frame mobile on the track;
- a pick-up device for picking up ballast located underneath the track;
- and
- a track lifting device mounted for vertical and transverse adjustability by way of drives;
- a first signal receiver configured for position detection in a global navigation satellite system for tracing an existing track position, said first signal receiver being mounted on the machine in front of the said pick-up device with regard to a working direction;
- a second signal receiver mounted following, with regard to the working direction, and configured for position detection in the global navigation satellite system and connected to the machine for tracing a new track position created by placing a raised track onto a reintroduced ballast;
- a control device associated with said first and second signal receivers and configured for actuation of said drives for shifting said track lifting device relative to said machine frame.
A machine for maintenance of a track, the machine comprising:
- a machine frame mobile on the track;
- a pick-up device for picking up ballast located underneath the track;
- a track lifting device vertically and transversely adjustable by way of drives;
- a first signal receiver configured as an inertial measuring unit for tracing an existing track position, said first signal receiver being connected to the machine in front of said pick-up device with regard to a working direction;
- a second signal receiver connected to said machine and configured as an inertial measuring unit for tracing a new track position created by placing a raised track upon a reintroduced ballast, said second signal receiver being is arranged following with regard to the working direction;
- and
- a control device associated with said first and second inertial measuring units and configured for actuation of said drives that shift said track lifting device relative to said machine frame.
