Method for manufacturing a crossing (diamond, frog) with moving point and crossing (diamond, frog) thus obtained

摘要

The present invention relates to a method for manufacturing a crossing (diamond, frog) with a moving point 1 for railway apparatuses of very great length incorporated in long welded rails, the said crossing (diamond, frog) furthermore comprising in particular a cradle 2 comprising two elements 3, 4, one moulded and the other not moulded, and a crossing (diamond, frog) thus obtained. Method, characterised in that it essentially consists in welding, on the point side, the moulded element 3 of the cradle 2 to the running rails 7 of the intermediate track of the connection, as well as in fixing pieces 5 and 5' to the movable point 1 in order to form the non-moulded element 4 of the cradle 2, then in rigidifying the said non-moulded element 4, then in connecting together, by means of an unwelded assembly, the two sub-assemblies thus formed, namely that formed by the moulded element 3 welded to the running rails 7 and that formed by the non-moulded element 4 fixed to the pieces 5, 5' and to the movable point 1, and finally in welding, if necessary, on the heel side, the moving point 1 to the running rails 9.
