To solve the problem of a conventional track tamping device that it is difficult to reduce weight or size.SOLUTION: In a vibrating compaction device 10 of the present invention, a vibrating rotating shaft 27 and a vibrating part 13 are arranged inside a housing body part 14. Vibrating plates 34 constituting the vibrating part 13 are dividedly arranged on a lower end side of the vibrating rotating shaft 27. And the vibrating plates 34 are arranged between bearings 31, 32, 33 arranged on the vibration rotating shaft 27. Thanks to this structure, when the vibrating rotating shaft 27 rotates, external force that the vibrating rotating shaft 27 receives from the vibration plates 34 is dispersed, and a deflection amount of the vibrating rotating shaft 27 is reduced. Further, by increasing a contact area between the housing body part 14 and the bearings 31, 32, 33, external force that the housing body part 14 receives from the vibrating plates 34 is dispersed. As a result, a selection width of materials for the vibrating rotating shaft 27 and the housing body 14 is increased, and the size and weight of the vibrating compaction device 10 can be reduced.SELECTED DRAWING: Figure 3A
【課題】従来の軌道用タンピング装置では、軽量化や小型化が実現され難いという課題があった。【解決手段】本発明の振動締め固め装置１０では、振動回転軸２７及び振動部１３が、筐体部１４の内部に配設される。振動部１３を構成する振動プレート３４が、振動回転軸２７の下端側に分割して配設される。そして、振動プレート３４は、振動回転軸２７に配設されるベアリング３１，３２，３３の間に配設される。この構造により、振動回転軸２７の回転時に、振動回転軸２７が振動プレート３４から受ける外力が分散され、振動回転軸２７の撓み量が低減される。また、筐体部１４とベアリング３１，３２，３３との接触面積が増大することで、筐体部１４が振動プレート３４から受ける外力が分散される。その結果、振動回転軸２７や筐体部１４の材料の選択幅が増え、振動締め固め装置１０の小型化や軽量化が実現される。【選択図】図３Ａ
