Technical field
[0001] The present invention relates to the field of rail repair technology, and specifically to a repair system based on laser cladding rail.

Background technology
[0002] Railway track is referred to as rail, rail, track, etc., and is mainly used on railways. Railway track is usually composed of two parallel rails, which are fixed on sleepers, and ballast is under the sleepers.
[0003] During the use of rails, due to the open air environment, rain, sun, temperature difference between day and night, wind, sun and rain, erosion causes different degrees of corrosion, and rust will appear on the surface of the rails. In particular, there are fewer vehicles on the side lines and newly laid tracks, and a layer of oxide layer, namely rust, is easily formed on the surface. The oxide layer continues to intensify, and the rusted rails will affect the smooth operation of the vehicle, thereby accelerating the damage of the rails. In particular, if the two sides of the rails are severely rusted and not cleaned for a long time, the aging of the rails will be accelerated, the service life will be reduced, and in severe cases, malignant accidents such as train rear-end collisions will be caused.
[0004] At present, the existing rail rust removal methods generally rely on manual grinding or manual grinding wheel grinding of the rail surface for rust removal, but manual grinding and manual grinding wheel grinding are not only inefficient, but also have high work intensity, slow rust removal speed, unsatisfactory rust removal effect, and consume a lot of manpower and resources. This is the deficiency of the prior art.
[0005] At the same time, when the track is used for too long, on the one hand, the train wheels are in long-term friction contact with the track; on the other hand, the track will rust and fall off, which will cause the track to wear. When the wear reaches a certain level, it is necessary to take measures to replace the track. When replacing the track, the single section of the track is generally long, and the staff needs to manually carry and replace it, which takes a long time and easily affects the operation of the train. This is the second shortcoming of the prior art.
