PACKING-AND-RAMMING TOOL USED FOR RAIL TRACK BALLAST (VERSIONS) Russian patent published in 2008 - IPC E01B27/16 E01B27/12 

FIELD: road construction industry.

SUBSTANCE: inventions refer to railroad engineering, and namely to rail track ballast packing tools, and are used for construction and repair of rail track. Packing-and-ramming tool used for rail track ballast consists of rod, the lower end of which is made in the form of beater. Rigid ramming head is fixed on rod above beater. As per the first version cross section of ramming head in the plane parallel to longitudinal axis of rod and perpendicular to beater's plane represents the shape selected from group that includes circle, ellipse, rhomb, triangle, polygon and star-shaped figure. As per the second version ramming head is made either in the form of flexible plate around rod, which is rigidly fixed on rod perpendicular to its longitudinal axis, or in the form of two flexible ramming elements located on rod's sides above upper edges of beater and rigidly fixed on rod, or with possible turning around axis that crosses longitudinal axis of rod. As per the third version ramming head is made in the form of plate around rod, which is rigidly attached to rod perpendicular to its longitudinal axis.

EFFECT: increasing the scope and degree of ballast packing per one tool's cycle.
