BEATER FOR TIE TAMPER
To provide a beater for tie tamper that can easily perform tamping even when a roadbed is deteriorated, pulverized, and solidified due to the influence of train running, rainwater, climate, and the like.SOLUTION: A beater 10 includes a tapered part 11, a same width part 12, and a pointed part 13 from a base end 10b of a strip-shaped flat plate member in a longitudinal direction L toward a tip 10a. The tapered part 11 has a shape in which it is widened continuously from the base end 10b to the tip 10a to a position closer to the tip that is half the length from the base end 10b to the tip 10a. The same width part 12 has a shape in which a total width W is constant from a maximum width part 11a of the tapered part 11 toward the tip 10a. The pointed part 13 has a shape in which the width is reduced continuously from a position 11b near the tip 10a of the same width part 11 toward the tip 10a. The same width part 12 has an inflection part 12a having a dogleg shape in a side view, and a curved part 13a having the longitudinal direction L as a valley longitudinal direction in a region near the tip 10a from the inflection part 12a.SELECTED DRAWING: Figure 1
【課題】列車走行、雨水、気候などの影響によって劣化、粉泥化し、固結した道床であっても容易に搗き固めすることができるタイタンパー用ビーターを提供する。【解決手段】ビーター１０は、短冊状の平板材の長手方向Ｌの基端１０ｂから先端１０ａに向かってテーパ部１１、同幅部１２並びに尖り部１３を備えている。テーパ部１１は基端１０ｂから先端１０ａまでの長さの半分より先端寄りの位置まで基端１０ｂから先端１０ａに向かって連続的に拡幅した形状をなし、同幅部１２がテーパ部１１の最大幅部１１ａから先端１０ａに向かって全幅Ｗが一定の形状をなし、尖り部１３が、同幅部１１の先端１０ａ寄りの位置１１ｂから先端１０に向かって連続的に縮幅した形状をなし、同幅部１２に、側面視形状がく字状をなす変曲部１２ａを有し、変曲部１２ａから先端１０ａ寄りの領域に長手方向Ｌを谷長手方向とする湾曲部１３ａを有する。【選択図】図１
