Description

Technical Field

[0001] This utility model relates to the field of railway engineering machinery, and in particular to a continuous rail welding operation system. Background Technology

[0002] my country's existing railways mainly use seamless steel rails, and in the construction of railways, it is often necessary to continuously weld short rails into long rails.

[0003] The existing methods mainly involve two approaches: rail welding bases and rail welding vehicles. Rail welding bases have high construction costs and long construction periods, and cannot be moved. On the other hand, existing rail welding vehicles have low operating efficiency and are only suitable for short-term welding at the construction site. This limits the use of rail replacement, rail matching, and rail unloading, which require continuous rail welding. The short rails are transported to the site for continuous on-site welding.

However, these rail welding vehicles can only complete rail welding operations on their own, which is not convenient to connect with processes such as transportation, rail unloading and rail replacement, and is not conducive to the development of integrated construction vehicles. Moreover, these rail welding vehicles can only perform single-sided rail welding, and the rail welding efficiency is relatively low.
