Abstract
In a method of renewing ties of a railroad track extending in a longitudinal direction and including a succession of ties supported on a ballast bed, damaged old ties are comminuted either before removal from the track or after removal of the track and subsequently ejected into a storage wagon by a first conveyor device extending longitudinally in the direction of the track. The comminuted ties are then transported via a second conveyor device, extending in the longitudinal direction, to a number of further like storage wagons arranged behind one another, for selectively filling the further storage wagons, whereas new tie replace the removed damaged ties.
Claims12
A method of renewing ties of a railroad track, comprising the steps of:
- (a) providing a lifting device for gripping and lifting a damaged tie from the ballast bed and for gripping a new tie and laterally inserting the gripped new tie under the rails of the track;
- (b) comminuting the damaged tie into pieces in one of the phases selected from the group consisting of before removal of the damaged tie and after removal of the damaged tie;
- (c) ejecting the pieces into a storage wagon by a first conveyor device;
- (d) transporting the pieces from the storage wagon by a second conveyor device to a number of further like storage wagons arranged behind one another, for selectively filling the further storage wagons;
- and
- (e) replacing the damaged tie in the track by the new tie.
A method of renewing ties of a railroad track, comprising the steps of:
- (a) providing a lifting device for gripping and lifting a damaged tie from the ballast bed and for gripping a new tie and laterally inserting the gripped new tie under the rails of the track;
- (b) removing the damaged tie from the track;
- (c) comminuting the damaged tie into shredded pieces;
- (d) ejecting the shredded pieces into a storage wagon by a first conveyor device;
- (e) transporting the shredded pieces from the storage wagon by a second conveyor device to a number of further like storage wagons arranged behind one another, for selectively filling the further storage wagons;
- and
- (f) replacing the damaged tie in the track by the new tie.
A method of renewing ties of a railroad track, comprising the steps of:
- (a) providing a lifting device for gripping and lifting a damaged tie from the ballast bed and for gripping a new tie and laterally inserting the gripped new tie under the rails of the track;
- (b) comminuting the damaged tie, laying in the track, into cut pieces;
- (c) removing the cut pieces from the track;
- (d) ejecting the cut pieces into a storage wagon by a first conveyor device;
- (e) transporting the cut pieces from the storage wagon by a second conveyor device to a number of further like storage wagons arranged behind one another, for selectively filling the further storage wagons;
- and
- (f) replacing the damaged tie in the track by the new tie.
A method of loading damaged ties from a railroad track, comprising the steps of
- (a) providing a lifting device for gripping and lifting a damaged tie from the ballast bed and for gripping a new tie and laterally inserting the gripped new tie under the rails of the track;
- (b) comminuting the damaged tie into cut pieces;
- (c) ejecting the cut pieces into a storage wagon by a conveyor device;
- (d) transporting the pieces by a bottom conveyor belt, situated longitudinally in the storage wagon, to a transfer conveyor belt, which extends the bottom conveyor belt beyond an end of the storage wagon;
- and
- (e) ejecting the cut pieces into a further, adjoining storage wagon.
A method of loading damaged ties lifted from a railroad track supported on a ballast bed, comprising the steps of:
- (a) lifting a damaged tie from the ballast bed by providing a lifting device for gripping and lifting the damaged tie from the ballast bed and for gripping a new tie and laterally inserting the gripped new tie under the rails of the track;
- (b) comminuting the damaged tie into shredded pieces in a comminuting device;
- (c) ejecting the shredded pieces into a storage wagon by a conveyor device;
- and
- (d) transporting the shredded pieces by a bottom conveyor belt, situated longitudinally in the storage wagon, to a transfer conveyor belt, which extends the bottom conveyor belt beyond an end of the storage wagon, for optionally ejecting shredded pieces into a further, adjoining storage wagon.
An on-track installation for lifting damaged ties from a railroad track and storing the damaged ties, said installation comprising:
- (a) a lifting device configured for gripping and lifting a damaged tie from the ballast bed and for gripping a new tie and laterally inserting the gripped new tie under the rails of the track;
- (b) a depositing station for intermediate storage of the damaged tie;
- (c) a comminuting device configured for receiving the intermediately stored damaged tie and for comminuting the damaged tie into pieces;
- (d) a conveyor device receiving the pieces from the comminuting device, said conveyor device extending longitudinally in a direction of the track and including a discharging end for ejecting the pieces;
- and
- (e) at least one storage wagon having one end distal to the conveyor device and including a bottom conveyor belt, which extends in the longitudinal direction, and a transfer conveyor belt, which extends the bottom conveyor belt beyond the distal end of the storage wagon and has a discharging end positioned higher than the bottom conveyor belt.
