Description

Technical Field

[0001] This utility model relates to the field of expansion rail cutting and splitting, and in particular to a hydraulic expansion rail cutting and splitting device. Background Technology

[0002] Summer track replacement work on seamless railway lines faces severe challenges, especially on short-distance tracks after thermal expansion. High temperatures cause compressive stress in the rails, and during the cutting process, stress concentration can cause the saw blade to become clamped, requiring specialized techniques to complete the cut. After cutting, the rails are tightly packed together due to compressive stress, making them particularly stubborn on short-distance tracks where thermal expansion is significant. The conventional method of using two track dividers to separate them in opposite directions is difficult, inefficient, and poses a safety hazard of personnel being injured by rail impacts.
