Apparatus for the truncation of railway rails

摘要

A portable cutting apparatus (1) for the in situ truncation of railway rails (9) comprises a rail saw (2) having a motor (3) with a cyclic movement output member (4), a plate holder (5) adapted to carry an abrasive blade (6) and a movement transmitter (7) engaging the motor output member (4) and the plate holder (5) to set the plate holder (5) in a cyclic movement, a linkage structure (27) with a rail connector (29) and a saw connector (31) and a sawing position alternator (45) to autonomously and alternately move the plate holder (5) to and fro.

1. Portable cutting apparatus (1) for the in situ truncation of railway rails (9), comprising:
a rail saw (2) having a motor (3) with a cyclic movement output member (4), a plate holder (5) adapted to carry an abrasive blade (6) and a movement transmitter (7) engaging the motor output member (4) and the plate holder (5) to set the plate holder (5) in a cyclic movement, a linkage structure (27) having a base portion (28) with a rail connector (29) for locking the linkage structure (27) to the rail (9) to be truncated and a guide arm (30) with a saw connector (31) for locking the rail saw (2) to the linkage structure (27), said guide arm (30) being movably linked to the base portion (28) such as to allow a first guided movement (1) of the rail saw (2) locked to the saw connector (31) toward and away from the rail (9), a sawing position alternator (45) interposed between the guide arm (30) and the plate holder (5) and configured to autonomously and alternately move the plate holder (5) to and fro with respect to the guide arm (30).
