Abstract

A cleaning vehicle ( 1 ) for cleaning ballast ( 2 ) of a track ( 4 ) with a rail vehicle ( 10 ) has a screening installation ( 15 ) provided for the ballast cleaning. A gantry crane ( 6 ) mobile on the rail vehicle ( 10 ) via crane rails ( 8 ) in a longitudinal direction ( 7 ) of the vehicle is provided for the transport of the ballast ( 2 ) stored in containers ( 11 ). Forming a discharge station ( 12 ) for discharging the soiled ballast ( 2 ), a receiving end ( 13 ) of a first conveyor belt ( 14 ) is provided, the latter having a discharge end ( 16 ) positioned above the screening installation ( 15 ). Forming a loading station ( 17 ) for discharging the cleaned ballast ( 2 ) into an empty container ( 11 ), a discharge end ( 18 ) of a second conveyor belt ( 19 ) is provided, the receiving end ( 20 ) of which is associated with an outlet opening ( 21 ) of the screening installation ( 15 ).

First claim

1 . A cleaning vehicle ( 1 ) for cleaning ballast ( 2 ) of a track ( 4 ), including a rail vehicle ( 10 ) and a screening installation ( 15 ) provided for ballast cleaning, comprising the following features:
a) a gantry crane ( 6 ) mobile on the rail vehicle ( 10 ) via crane rails ( 8 ) in a longitudinal direction ( 7 ) of the vehicle is provided for the transport of the ballast ( 2 ) stored in containers ( 11 ), b) forming a discharge station ( 12 ) for discharging the soiled ballast ( 2 ), a receiving end ( 13 ) of a first conveyor belt ( 14 ) is provided, the latter having a discharge end ( 16 ) positioned above the screening installation ( 15 ), c) forming a loading station ( 17 ) for discharging the cleaned ballast ( 2 ) into an empty container ( 11 ), a discharge end ( 18 ) of a second conveyor belt ( 19 ) is provided, the receiving end ( 20 ) of which is associated with an outlet opening ( 21 ) of the screening installation ( 15 ).

2 . The cleaning vehicle according to claim 1 , wherein the loading- and discharge stations ( 17 , 12 ), arranged one behind the other with regard to the longitudinal direction ( 7 ) of the vehicle, are arranged between two on-track undercarriages ( 3 ), while the screening plant ( 15 ) is positioned at an end ( 22 ) of a vehicle frame ( 5 ).

3 . The cleaning vehicle according to claim 1 , wherein the receiving end ( 13 ) of the first conveyor belt ( 14 ) and the discharge end ( 18 ) of the second conveyor belt ( 19 ) are each arranged underneath the vehicle frame ( 5 ) between the crane rails ( 8 ).

4 . The cleaning vehicle according to claim 1 , wherein the screening plant ( 15 ) is designed as a star screen ( 23 ) having a multitude of rotatable cleaning rollers ( 24 ) arranged one following the other in the longitudinal direction ( 7 ) of the vehicle.

5 . A method for cleaning ballast of a track on a rail vehicle ( 10 ), comprising the following features:
a) the soiled ballast ( 2 ) is transported in a container ( 11 ) from a loading area ( 9 )—containing a multitude of containers ( 11 )—of the rail vehicle ( 10 ) to a discharge station ( 12 ), is discharged onto a conveyor belt ( 14 ), and is transported by the same to a screening installation ( 15 ), b) the emptied container ( 11 ) is placed on a loading station ( 17 ), is filled with ballast ( 2 ) cleaned by the screening installation ( 15 ), and is subsequently transported back to the loading area ( 9 ) and placed on the same, after which the cycle according to features a) and b) is repeated.
