Abstract
In a tamping unit for tamping sleepers of a track, both squeezing drives of a tamping tine pair are articulatedly connected to a common connecting carrier. A vibration exciter fastened to the tine carrier is connected to the connecting carrier, likewise fastened to the tine carrier, for transmission of tamping tine vibrations from the connecting carrier to the squeezing drives and the tamping tines.
Claims9
A tamping unit for tamping sleepers of a track, comprising:
- an assembly frame;
- a plurality of tamping tines;
- a tine carrier mounted for vertical adjustment on said assembly frame and connected to said plurality of tamping tines, wherein tamping tines which are mounted on the tine carrier for pivoting towards one another in pairs form a tamping tine pair;
- a hydraulic squeezing drive coupled to said plurality of tamping tines;
- a vibration exciter which is designed to set said plurality of tamping tines into tamping tine vibrations,
- a common connecting carrier wherein said hydraulic squeezing drives of a tamping tine pair of said plurality of tamping tines are articulatedly connected to said common connecting carrier,
- wherein the vibration exciter fastened to the tine carrier is connected to the common connecting carrier for transmission of the tamping tine vibrations from the common connecting carrier to the hydraulic squeezing drives and to the plurality of tamping tines.
A tamping unit for simultaneously tamping two sleepers of a track, comprising:
- an assembly frame;
- a hydraulic squeezing drive;
- a common connecting carrier;
- a vibration exciter;
- a tine carrier mounted for vertical adjustment on said assembly frame;
- a plurality of tamping tines coupled to said tine carrier, said plurality of tamping tines arranged one behind the other, wherein the plurality of tamping tines are mounted on the tine carrier for pivoting towards one another in pairs about a pivot axis and form a tamping tine pair in each case are each connected to said hydraulic squeezing drive and are designed to be set into tamping tine vibrations by means of a vibration exciter,
- wherein:
- said hydraulic squeezing drives of both tamping tine pairs are articulatedly connected to a said common connecting carrier,
- said vibration exciter, fastened to the tine carrier, is connected to the common connecting carrier for transmission of the tamping tine vibrations from the common connecting carrier to the squeezing drives and to the plurality of tamping tines.
A tamping unit for simultaneously tamping at least three sleepers of a track, comprising:
- an assembly frame;
- a plurality of hydraulic squeezing drives;
- a vibration exciter;
- a plurality of tine carriers which are vertically adjustable independently of one another and mounted for vertical adjustment on said assembly frame;
- a plurality of tamping tines coupled to said plurality of tine carriers, said plurality of tine carries arranged one behind the other, wherein the plurality of tamping tines which are mounted on the tine carrier for pivoting about a pivot axis are each connected to at least one of said plurality of hydraulic squeezing drives and are designed to be set into tamping tine vibrations by means of said vibration exciter, wherein:
- a) the squeezing drives of all of the plurality of tamping tines mounted on a common tine carrier are articulatedly connected to a common connecting carrier,
- b) each common connecting carrier is connected to a vibration exciter, fastened to the tine carrier, for transmission of the tamping tine vibrations from the common connecting carrier to the squeezing drives and to the plurality of tamping tines.
