RU94033093A - Design of insertion piece with cantilevered-support overlapping the gap of rail joint - Google Patents

Abstract

FIELD: rail way track repair. SUBSTANCE: gap overlapping is provided by eliminating mutual displacement of heights of roll surfaces of insertion piece heads, hence, eliminating the step due to providing support area in head cell of one half-insertion piece being a support for head cantilever of another half- insertion piece when lowering under wheel pressure of the forthcoming vehicles. Lack of the step contributes to elimination of additional dynamic forces in the area of rail joint that result in reducing service life of rail way tracks and rolling stock. Insertion piece is made apart from the rails that allows one to eliminate specific technological difficulties related to long articles, as well as increase possibilities in improving local metal quality in the area of rail joint. The insertion piece is connected to rail butts immovably prior to running the rails into track. EFFECT: improved rail way track quality. 2 cl, 1 dwg

The design of the insert with cantilever-overlapping overlap of the gap of the rail joint is designed for high-quality overlap of the gap of the joined rails and can be used in the construction and repair of the rail track of urban and railway transport. Qualitative overlapping of the gap is ensured by eliminating the mutual displacement along the height of the rolling surfaces of the insert heads, and, therefore, by eliminating a step due to the arrangement of a support platform in the head cell of one of the half-inserts, on which the console of the head of the other half-insert rests when it lowers under the pressure of the wheels of the approaching transport. The absence of a step eliminates the appearance in the joint zone of additional dynamic forces leading to a reduction in the service life of rail tracks and mobile vehicles. The design of the insert is made separately from the rails, which eliminates certain technological difficulties associated with long products, and also extends the possibility of improving the quality of the metal locally in the joint zone with minimal cost. The insert is fixedly connected to the ends of the rails before preparing for laying the rails in the path. 1 s.p. f-ly, 1 ill.
