The technical solution of the utility model is: a kind of battering ram, comprise body, handrail is installed on the body, be connected with the torsional mode damping device between described body and the handrail, this torsional mode damping device comprises overcoat, be inserted with the torsion bar axle that can rotate relative to overcoat in the trepanning of overcoat, be press-fitted between the cover hole wall of this torsion bar axle and overcoat and hinder the elastic damping part that the torsion bar axle rotates with respect to overcoat, on described overcoat and torsion bar axle, also be respectively equipped with the installation connecting hole that is connected body and handrail.
It is foursquare square structure that described torsion bar axle and overcoat trepanning are the cross section, and four jiaos of torsion bar axle and overcoat trepanning form the triangle cavity respectively, and described elastic colloid is leg-of-mutton rubber shock-absorbing bar for the cross section identical with this cavity body structure.
Between described overcoat and torsion bar axle, also be provided with axial positioning structure.
Described axial positioning structure comprise that the cover bore edges that is positioned at overcoat one side end face radially is provided with towards the convex annular edge in axle center, at the opposite side end face of overcoat near being provided with end cap.
Described axial positioning structure comprises on the end face of overcoat one side and to be positioned at the trepanning edge and to offer annular groove on overcoat opposite side end face near the end cap that is provided with, and radially is provided with the convex annular edge corresponding with this annular groove in an end end of described torsion bar axle; The other end end face center of torsion bar axle offers groove, and described end cap thrust is assemblied in this groove.
The outer rim end face of described closed end cap is provided with the convex annular edge of diameter greater than the overcoat trepanning, and described overcoat end face is provided with annular groove that should the convex annular edge.
Described installation connecting hole is bolt hole or the screwed hole that is provided with vertically.
Adopt said structure, the handrail of battering ram is installed on the body of rammer machine by the torsional mode damping device, when the rammer machine is worked, can effectively alleviate the vibrations of rammer machine handrail, make the switching impulse that the operator can be comfortable ram machine, alleviate working strength of workers, and can avoid the vibrations of rammer machine that workman's health is damaged.
