Abstract
A mobile apparatus for dynamically stabilizing a ballast bed supporting a track at a desired level comprises a reference for determining a deviation of the track grade from the desired level, a chassis running on the track rails on flanged wheels, vibrators for imparting at least approximately horizontal vibrations to the track engaged by the flanged wheels, a mechanism for laterally pressing the flanged wheels into play-free engagement with their associated rails, the flanged wheels and the vibrators being arranged on the chassis to vibrate in unison to transmit the vibration to the track, the loads associated with each rail and supplemental to the weight of the apparatus for imparting a pressure to the rails in the direction of the ballast bed whereby the vibrating track is pressed to a lower level.
Claims22
In a mobile apparatus for compacting ballast of a ballast bed supporting a track consisting of two rails fastened to ties resting on the ballast, which comprises means for determining a deviation of the track position from a desired level, a chassis having a pair of rail engaging and guiding means spaced in the direction of track elongation and associated with each of the rails and mounting the chassis for mobility on the track, means for imparting at least approximately horizontal vibrations to a section of the track engaged by the rail engaging and guiding means, the vibration imparting means being a vibration producing means arranged on the chassis, and load means in the region of, and associated with, the vibration imparting means for imparting a pressure to both rails of the track in the direction of the ballast bed whereby the track is pressed to a lower level while being vibrated, the improvement of the vibration imparting and load means being associated with the rail engaging and guiding means for simultaneously laterally vibrating and vertically loading each of the rail engaging and guiding means, and further comprising means for pressing the rail engaging and guiding means associated with each rail without play with respect to the chassis and against the rail with which it is associated, the load and the vibration producing means being arranged on the chassis to load and vibrate the rail engaging and guiding means in unison whereby the rail engaging and guiding means transmit the vibration and load to the track section.
