In one embodiment, the shaft of the jack is arranged through a limiting ring on the gangue stopping seat.

The utility model has the advantages as follows:

1. the utility model discloses a setting of tamping unit's structure, through the connection of jack, connecting rod and swing beam, current device of comparing only directly acts on the swing beam through the jack, and the swing beam rotation range further improves, and then has enlarged the tamping head to the regional compaction scope of filling in the sky.

2. The utility model discloses because the interlock of jack, connecting rod is used for need not set up two swing beams, the jack also need not excessively stretch out and draw back and can make swing beam rotation range enlarge, and then the life of extension jack, the interlock of jack, connecting rod simultaneously makes each part atress comparatively balanced, further makes the rotation of swing beam more stable, simultaneously because the characteristics of connecting rod interlock, makes its wearing and tearing lighter, bearing capacity is high.
