Description

Technical Field

[0001] The invention relates to the field of railway engineering machinery, and in particular to a continuous rail welding operation system and an operation method thereof. Background Art

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

[0003] The existing methods mainly use two methods: rail welding base and rail welding vehicle. The construction cost of the rail welding base is high, the construction period is long, and it cannot be moved. The existing rail welding vehicle has low operating efficiency and is only suitable for short-term welding at the construction site, which limits the use of rail replacement, rail matching and rail unloading that require continuous welding of rails. The short rails are transported to the site for continuous on-site welding.

[0004] Patent applications with announcement numbers CN110977221A, CN201835195U and CN104499390A proposed in the prior art disclose several rail welding vehicles for rail welding. However, these rail welding vehicles can only complete rail welding operations alone, which is not convenient for connection with processes such as transportation, rail unloading and rail changing, and is not conducive to the research and 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.

[0005] Therefore, it is necessary to provide a continuous rail welding operation system to solve the above-mentioned technical problems. Summary of the invention

[0006] The present invention provides a continuous rail welding operation system, which solves the problem of two modes, namely, a rail welding base and a rail welding vehicle. The rail welding base has high construction cost, long construction period and cannot be moved, while the existing rail welding vehicle has low operation efficiency and is only suitable for short-time welding at the construction site, which limits the use of rail replacement, rail matching and rail unloading that require continuous rail welding, and the problem of continuous on-site welding after transporting short rails to the site.
