Abstract
An apparatus for track machining contains a fastening device, at least one machining device and at least one vibration decoupler operating between the at least one machining device and the fastening device and having adjustable stiffness and/or adjustable damping for at least partially decoupling a movement of the fastening device from a movement of the at least one machining device.
Claims31
An apparatus for track machining, the apparatus comprising:
- a fastening device;
- at least one machining device for at least one of compacting a track bed and for tightening and loosening a screw connection;
- and
- at least one vibration decoupler with at least one of an adjustable stiffness and an adjustable damping to at least partially decouple said fastening device and said at least one machining device.
1 more element
A method for operating an apparatus for track machining, which comprises the steps of:
- providing at least one machining device disposed on a vibration decoupler;
- adjusting the vibration decoupler between a first coupling state in which the vibration decoupler has at least one of a first stiffness and a first damping, and a second coupling state in which the vibration decoupler has at least one of a second stiffness different from the first stiffness and a second damping different from the first damping;
- and
- performing at least one of compacting a track bed and tightening and loosening a screw connection by means of the at least one machining device.
1 more element
A tamping assembly for track bed treatment, comprising:
- a fastening device;
- a machine motor;
- at least one tamping unit having a penetrator, being formed as a tamping pick tube, and a vibration generator, wherein at least one of said vibration generator and said machine motor is disposed in said tamping pick tube;
- and
- a displacement device for at least one of displacing and pivoting said at least one tamping unit relative to said fastening device.
