Title:
VIBRATION COMPACTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/166234
Kind Code:
A1
Abstract:
Prior-art tamping devices for tracks have had problems in that the rotating shaft of an engine and the rotating shaft of a vibration-generating section are directly linked, and vibration from the vibration-generating section is readily transmitted to the engine. This vibration compaction device 10 comprises a linking mechanism 14 that links a motive power section 11 and a vibration section 13, and the linking mechanism 14 has a first shaft joint section 26 to which a drive transmission section 21 of the motive power section 11 is mounted, a second shaft joint section 27 to which a drive transmission section 30 of the vibration section 13 is mounted, and a linking member 28 that links the first shaft joint section 26 and the second shaft joint section 27. Due to this structure, the drive transmission section 21 and the drive transmission section 30 are not directly linked, vibration generated in the vibration section 13 is not readily transmitted to the motive power section 11, and the motive power section 11 is driven in a stable state, whereby damage to the components of the motive power section 11 and decrease in life span are prevented.
