Abstract
A work train lays a rail of a railway track. The work train has a heating device with a heating zone, gas burners, and a radiant body interposed between the gas burners and the heating zone. The radiant body has openings that open into the heating zone. The work train is moved in a laying direction, so that at each moment a portion of the rail to be fixed passes through the heating zone. Heat is supplied to the rail to be fixed through the heating zone by feeding the gas burner so that no flame emerges from the openings in the heating zone and that at least 75% of the heat supplied to the rail is transmitted by radiation from the radiant body. Then the rail is fixed after the heat has been applied to a tie of the railway track behind the heating zone in the laying direction.
Claims19
A method for laying a rail of a railway track using a work train having at least one heating device with at least one heating zone, at least one gas burner, and at least one radiating body interposed between the gas burner and the heating zone, the radiating body being perforated with openings opening into the heating zone, which comprises the steps of:
- moving the work train in a laying direction in such a way that at each instant, a portion of the rail not fixed to a tie passes through the heating zone;
- applying, by means of the heating device, heat to the portion of the rail that passes through the heating zone;
- and
- supplying the gas burner in such a way that no flame emerges from the openings into the heating zone and that at least 75% of the heat applied to the portion of the rail is transmitted by radiation from the radiating body.
A work train, comprising:
- at least one heating device having at least one heating zone, at least one gas burner, and at least one radiating body being interposed between said gas burner and said heating zone, said radiating body having perforated openings formed therein opening into said heating zone;
- traction means for moving the work train in a laying direction in such a way that at any given point in time, a portion of a rail not fixed to a tie passes through said heating zone;
- and
- means for supplying said gas burner in such a way that no flame emerges from said perforated openings into said heating zone and that at least 75% of the heat applied to the portion of the rail is transmitted by radiation from said radiating body.
