Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rail joint fittings, in particular to a new type of railway rail joint misalignment adjusting piece. Background Technique
[0002] When the train is running, the rail will have vertical wear. When other parts of the rail are replaced, due to the different vertical wear of the new and old rails, it is necessary to cause the new rail to be slightly higher than the old rail, resulting in a misalignment phenomenon at the joint.
[0003] In the prior art, the method for dealing with the misalignment of railway rail joints is to use a strip of iron sheet, place it between the lower jaw of the rail on the low-lying side of the joint and the splint, and then tighten the bolts of the joint splint to lift the rail joint on the low-lying side to achieve the effect of eliminating the misalignment of the joint.
[0004] However, in use, this method has the following disadvantages: the profile design of the splint is completely fitted with the rail abdomen. By putting an iron sheet between the lower jaw of the rail and the splint to lift the low-lying rail to eliminate the misalignment, the rail bottom on the low-lying side will push the splint outwards, so that the splint cannot be completely fitted with the rail abdomen. As a result, after tightening the bolts of the joint splint, the splint is unevenly stressed, the joint strength is weak, and there is a great risk of train operation safety. For this reason, we have proposed a new type of railway rail joint misalignment adjusting piece. Content of the Utility Model
[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a new type of railway rail joint misalignment adjusting piece, which is assembled by two symmetric misalignment adjusting pieces on both sides. The shape of the misalignment adjusting piece completely matches the rail waist and the splint contour. The total thickness of the upper and lower edges of the adjusting piece is 20 mm, and the upper and lower edge thicknesses of each pair of adjusting pieces used before and after the misaligned joint are different. By changing the specifications of the misalignment adjusting pieces before and after the joint, the tops of the rails before and after the joint are made flush, achieving the effect of eliminating the misalignment, and effectively solving the problems in the background technique.
