PROBLEM TO BE SOLVED: To provide a hammering device in which each apex of an outer periphery of a rotation hammering tool does not slide and move on a road surface and contacts to the road surface with an equal interval and contacts to the road by impulsive grounding when a rotation hammering tool 2 is moved on the road in a state that the rotation hammering tool 2 is linked to a bogie 1.SOLUTION: A shape of an outer periphery 21 of a body 20 of a rotation hammering tool 2 is a polygon. When the body 20 is rotated on the road surface, each apex 22 of the outer periphery 21 contacts to a road surface 41 with an equal interval by impulsive grounding with outputting impact sound. The rotation hammering tool 2 is configured by the above-mentioned structure. The rotation hammering tool 2 is linked to a bogie 1 so as to track the bogie 1, an axle 15 of a wheel 14 of the bogie 1 and a central axis 25 of the body 20 of the rotation hammering tool are coupled with a belt 57 so that the central axis 25 of the body 20 of the rotation hammering tool rotates while maintaining a constant relationship with movement of the outer peripheral surface of the wheel 14, and contacts to the road surface 41 by impulsive grounding with the equal interval 24 without sliding. |
