Abstract
The tamping head of a mobile track tamper comprises two pairs of reciprocable ballast tamping tool implements, each pair being arranged at a respective side of each track rail, a reciprocating power drive for the ballast tamping tool implements of each pair, a carrier part associated with the ballast tamping tool implements, a pivot extending in the direction of elongation of the machine and supporting the carrier part for pivoting in a plane extending transversely thereto, and a vibrating power drive connected to the carrier part and imparting to the tamping tool implements an oscillatory vibrating motion in a plane extending perpendicularly to the pivot in each position of the tamping tool implements.
Claims10
A mobile track tamper comprising a frame arranged on a track consisting of a multiplicity of ties and two rails fastened to the ties, the rails intersecting each tie at respective points of intersection and ballast supporting the track rails at each point of intersection, and a tamping head vertically movably mounted on the frame for vertical alignment with the respective points of intersection, the tamping head including
- (a) a carrier supporting two pairs of ballast tamping tool implements arranged for reciprocation in the direction of track elongation towards and away from each other and a respective one of the ties positioned between the tamping tool implements of each pair, each pair of the ballast tamping tool implements being arranged at a respective side of each rail in a direction transverse to the track and the ballast tamping tool implements being immersible in the ballast upon vertical movement of the tamping head for tamping ballast under the respective tie upon reciprocation of the implements,
- (b) a reciprocating power drive for the ballast tamping tool implements of each pair,
- (c) a respective carrier part supporting a respective one of the pairs of the ballast tamping tool implements on each side of the rail,
- (d) a pivot extending in the direction of elongation of the machine and supporting the carrier part on the carrier for pivoting in a plane extending transversely of said direction, and
- (e) a vibrating power drive means connected to the carrier part and imparting to the tamping tool implements an oscillatory vibrating motion in a plane extending perpendicularly to the pivot in each position of the tamping tool implements.

- (b) a reciprocating power drive for the ballast tamping tool implements of each pair,
- (c) a respective carrier part supporting a respective one of the ballast tamping tool implements on each side of the rail, the carrier parts being arranged symmetrically with respect to a respective one of the rails with which the tamping head is associated,
- (d) a respective pivot extending in the direction of elongation of the machine and each one of the pivots supporting a respective one of the carrier parts on the carrier for pivoting in a plane extending transversely of said direction,
- (e) a vibrating power drive means connected to the carrier part and imparting to the tamping tool implements in oscillatory vibrating motion in a plane extending perpendicularly to the pivot in each position of the tamping tool implements.
- (f) a central vertical guide column between the symmetrically arranged carrier parts, the tamping tool implement carrier being vertically adjustably mounted on the guide column, a respective pivot supporting each tamping tool implement for reciprocation on the respective carrier part, and
- (g) a pair of elastic abutments mounted on the carrier and cooperating with the guide column and the carrier parts for centering the carrier parts in end positions of the oscillatory vibrating motion.
