Description

Technical Field

[0001] The invention relates to the technical field of rails, in particular to a rail joint misalignment adjustment pad. Background Art

[0002] Rail joints will develop various diseases after a long period of operation. The quality of rail joints will not only affect the quality of railway line equipment, but also have a great impact on the train's passing capacity and running speed. When the wheels of railway locomotives pass through the joints, they are prone to violent shaking due to their unevenness, which accelerates the change of line status and causes rail joint sinking, misalignment, rail gap enlargement, deformation and other joint diseases. In order to reduce the diseases of rail joints and improve the quality of line equipment, rail joints are often connected and adjusted through adjustment pads.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN2141817Y discloses a rail joint misalignment adjustment gasket, whose shape matches the shape of the fishplate near the rail, with a thickness of 0.5 to 4 mm, a hole in the middle, the diameter of the hole is larger than the diameter of the fishplate bolt, and the spacing between the holes is the same as the spacing between the bolt holes on the fishplate. When in use, according to the direction and degree of misalignment, a gasket of appropriate thickness is placed between the opposite rails and the fishplate of the two connected rails, and the tightening force of the fishplate bolt forces the two rails to move in the opposite direction of the misalignment, thereby achieving the purpose of adjusting the misalignment. It has the characteristics of simple structure, easy installation, labor saving and time saving, etc., and can conveniently and effectively adjust the misalignment of the joint, reduce the unevenness of the line and the workload of maintenance and repair.

[0004] For example, a Chinese utility model patent with authorization announcement number CN204417929U discloses a height-adjustable rail joint connection device, including a clamp, a bolt, an aperture for adjusting the height of the clamp, and a gasket used in conjunction with the aperture. The connection device of the utility model is used to solve the problem of uneven top surface of the rail joint caused by vertical wear of the top surface of the rail cross section due to long-term train rolling or large machine grinding and milling, which causes the joint rail misalignment disease. It effectively improves the smoothness of the rail joint, thereby improving driving safety; the construction process is convenient and fast, and the construction efficiency is high.

[0005] For example, the Chinese utility model patent with authorization announcement number CN206721578U discloses a rail leveling joint, in which a rail leveling splint is fixedly installed on both sides of the rail by bolts and nuts; the two sides of the middle part of the rail leveling splint corresponding to the joint of the two rails are respectively the high end side of the leveling splint and the low end side of the leveling splint, and a height difference matching the height difference of the two rails is provided between the upper surfaces of the high end side of the leveling splint and the low end side of the leveling splint, and between the lower surfaces of the high end side of the leveling splint and the low end side of the leveling splint, and a gasket matching the height difference of the two rails is installed at the lower part of the low rail. The utility model makes the rail leveling joint splint into a structure with different heights at both ends, and manufactures leveling joint splints of corresponding specifications according to different types of rail joints and different height differences of rail joints, thereby solving the problem of height misalignment of rail joints caused by wear, enhancing the smoothness and integrity of the line, extending the service life of the rail joints, and reducing costs.

[0006] The existing rail joint misalignment adjustment pads still have some problems during use, such as;

[0007] 1. During use, generally only the rail joint is adjusted and connected, which is not convenient for supporting and limiting the adjustment pad body, and it is difficult to ensure the misalignment adjustment of the rail joint;
