Abstract
A handling machine for handling rails, arranged in line immediately downstream of a rolling plant, which allows an optimal clamping of the rail along its longitudinal extension, thus effectively withstanding the deflection and its variations, while allowing a longitudinal movement of the rail caused by thermal shrinkage, thus avoiding damages both to the external surface of the rail and to the handlers. A process of handling the rail is also described, which optimizes moving, positioning along a roller table and maintaining the rail substantially rectilinear during the thermal treatment to which it is subjected.
Claims15
Handling machine for handling a rail (9) provided with a head and a flange, the machine comprising:
- a plurality of tilting means (20) for tilting the rail (9) from a first position inclined on a side thereof to a second position wherein the rail head is turned upwards;
- a plurality of handlers (10) provided with clamping means adapted to clamp the rail (9) at the flange, and adapted to move the rail (9) from said second position wherein the rail head is turned upwards to a third position wherein the rail head is turned downwards,
- wherein said clamping means are provided with two jaws (14), pivotable around respective pivoting pins (19) and configured so that the rail clamping occurs by contacting portions (31′, 31″) of internal surface of the jaws (14) only with the sides of the flange of the rail (9).
