Description

Technical Field

[0001] The utility model relates to the technical field of rail welding, in particular to a slope pad for rail welding on a railway line. Background Art

[0002] During the rail welding operation on the railway track replacement construction line, in order to prevent the rail welding vehicle from derailing and overturning, the traditional methods generally include: (1) sawing off the 12 bolts of the three sleepers before and after the welding head for rail welding, and re-anchoring the 12 bolts after the rail welding. However, this method will cause problems such as tight construction time, interference between work, and poor quality assurance; (2) placing iron blocks or square tubes at the bottom of the rail, but this method cannot lock the rails and sleepers to form an integral structure, and there are unsafe hidden dangers such as uncontrollable track gauge, downward sliding of the rails in curved sections, and rail rollover, which may cause the rail welding vehicle to derail; (3) installing hydraulic support legs on the rail welding vehicle. This method may cause the rail welding vehicle to derail in sections with small curve radius and large superelevation. Utility Model Content
