Abstract
System and method to harden rails by cooling, in a cooling medium, at least one part of a respective rail cross-section of a rail over an entire length of the rail. The system includes a cross displacement device arranged in an area of a roller table, at least one coolant container containing the cooling medium, a manipulation gripper structured and arranged to move the rail, and at least one positioning device comprising substantially horizontally aligned holding components having fittings structured and arranged to support a foot portion of the rail such that the rail hangs from the fittings.
Claims14
A system structured and arranged to harden rails by cooling, in a cooling medium, at least one part of a respective rail cross-section of a rail over an entire length of the rail, the system comprising:
- a cross displacement device arranged in an area of a roller table;
- at least one coolant container containing the cooling medium;
- a manipulation gripper structured and arranged to move the rail;
- at least one positioning device comprising substantially horizontally aligned holding components having fittings structured and arranged to support a foot portion of the rail such that the rail hangs from the fittings.
A system structured and arranged to harden rails by cooling, in a cooling medium, at least one part of a respective rail cross-section of a rail over an entire length of the rail, the system comprising:
- a cross displacement device arranged in an area of a roller table;
- a manipulation gripper structured and arranged to move the rail;
- at least two coolant containers horizontally arranged substantially adjacent and parallel to one another, each coolant container being oriented in an axial direction and containing the cooling medium;
- and
- at least one positioning device arranged in an area of each coolant container having fittings structured and arranged to support a foot portion of the rail while at least an unsupported portion of the rail hanging below the foot portion is submerged in a respective one of the at least two coolant containers.
A system structured and arranged to harden rails by cooling, in a cooling medium, at least one part of a respective rail cross-section of a rail over an entire length of the rail, the system comprising:
- a cross displacement device arranged in an area of a roller table;
- at least one coolant container containing the cooling medium;
- a manipulation gripper structured and arranged to move the rail;
- at least one positioning device comprising fittings and detachable clamping devices structured and arranged to support a foot portion of the rail such that the rail hangs from the fittings,
- wherein the at least one positioning device is vertically movable and/or adjustable in a controlled manner.
