Abstract
A railroad tie hardware removing apparatus and methods are provided. The apparatus includes one or more tool mechanisms each carrying one or more tools. The tools are positionable relative to a mounting structure or tower of a concrete railroad tie to remove the tower therefrom. Once the towers are removed, the tie can be pulled from underneath rails supported by the tie.
Claims15
A railroad tie hardware removing apparatus for removing mounting structures used to affix the rails of a railroad track to a concrete railroad tie, the railroad tie hardware removing apparatus comprising:
- a frame configured for travel upon the rails of the railroad track;
- at least one tool adapted to break the mounting structures;
- at least one tool mechanism mounted to the frame, the at least one tool carried by the at least one tool mechanism;
- and
- wherein the at least one tool mechanism is operable to transition the at least one tool from a stored position wherein the at least one tool is spaced above the mounting structures, and a working position wherein the at least one tool is in contact with one of the mounting structures.
A railroad tie hardware removing apparatus for removing mounting structures used to affix the rails of a railroad track to a concrete railroad tie, the railroad tie hardware removing apparatus comprising:
- a frame configured for travel upon the rails of the railroad track;
- at least one tool adapted to break the mounting structures;
- at least one tool mechanism mounted to the frame, the at least one tool carried by the at least one tool mechanism;
- wherein the at least one tool mechanism is operable to transition the at least one tool from a stored position wherein the at least one tool is spaced above the mounting structures, and a working position wherein the at least one tool is in contact with one of the mounting structures;
- and
- wherein the at least one tool mechanism includes a first and a second tool arm, and the at least one tool includes a first and a second tool carried, respectively, by the first and second tool arms, the first and second tool arms mechanically coupled at a first common mounting point to a mounting hub, and mechanically coupled to one another by a scissor mechanism.
A method for removing a mounting structure used to affix a pair of rails of a railroad track to a concrete railroad tie, the method comprising:
- positioning a frame carrying at least one tool mechanism over the mounting structure;
- extending at least one tool carried by the at least one tool mechanism from a stored position to a working position, wherein in the working position the at least one tool contacts the mounting structure;
- and
- breaking the mounting structure by applying a force against the mounting structure at a selected orientation using the tool.
