Tamping machine for compacting the ballast bed of a track

Abstract

A tamping machine ( 1 ) for compacting the ballast bed of a track ( 9 ), has tamping units ( 4 ) for tamping under a track, with a lifting-straightening device ( 2 ) arranged between running gears ( 8 ), preferably in front of the tamping units ( 4 ) in the working direction (C), for lifting and straightening tracks and railroad switches, having at least one height-adjustable lifting roller ( 6 ) and having at least one lifting hook ( 7 ) that is height-adjustable independently of the lifting roller ( 6 ), the lifting roller ( 6 ) and the lifting hook ( 7 ) being arranged on a common console ( 31 ) that is guided displaceably transversely to the longitudinal axis (L) of the tamping machine by means of an adjusting drive ( 17 ). The console ( 31 ) is arranged on a guiding slide ( 10 ), with which it is displaceable transversely to the longitudinal axis (L) of the tamping machine along a transverse guide ( 16 ), and the console ( 31 ) is mounted on the guiding slide ( 10 ) so as to be pivotally adjustable about a pivot axis ( 30 ) parallel to the longitudinal axis of the tamping machine by means of a swivel drive ( 12 ).

         5 . The tamping machine according to  claim 1 , wherein a transverse displacement path of the transverse guide and a swivel range of the swivel drive are extended so that a rail can be gripped with the lifting roller both from the outside of the track and from the inside of the track. 
     
     
         6 . The tamping machine according to  claim 1 , wherein a swivel force limiter is operatively associated with the swivel drive so as to provide overload protection. 
     
     
         7 . The tamping machine according to  claim 1 , wherein the lifting-straightening device is arranged between the running gears and in front of the tamping units in a working direction. 
     
     
         8 . The tamping machine according to  claim 2 , wherein a rotation angle sensor is operatively associated with the swivel drive and/or a stroke path sensor is operatively associated with a swivel cylinder of the swivel drive. 
     
     
         9 . The tamping machine according to  claim 8 , wherein the displacement travel sensor of the displacement cylinder, the stroke path sensor of the vertical lifting cylinder for the lifting roller, the stroke path sensor of the vertical lifting cylinder for the lifting hook, and the stroke path sensor for the swivel cylinder are each integrated in the associated cylinder. 
     
     
         10 . The tamping machine according to  claim 5 , wherein, the rail can be gripped with a lifting hook having a T-shaped foot. 
     
     
         11 . The tamping machine according to  claim 2 , wherein a transverse displacement path of the transverse guide and a swivel range of the swivel drive are extended so that a rail can be gripped with the lifting roller—both from the outside of the track and from the inside of the track. 
     
     
         12 . The tamping machine according to  claim 3 , wherein a transverse displacement path of the transverse guide and a swivel range of the swivel drive are extended so that a rail can be gripped with the lifting roller—both from the outside of the track and from the inside of the track. 
     
     
         13 .
