Installation of thermal treatment of welded rail joints in the TRACK CONDITIONS

摘要

Installation of heat treatment of the welded joints of the rails in the travel conditions relates to the field of heat treatment of welded joints, e.g., elongated and continuous welded rails lashes, and can be used to correct zonal structural nonuniformity after welding railway rails, urban and industrial vehicles in traveling conditions. Induction heating for the thermal treatment of rails welded joints in terms of travel is composed of inductors system quenching unit and the system control unit inductors and quench unit, and the high-frequency power source. System and inductors quenching unit together with said control unit are combined into a single portable unit adapted to be freely movable along the runner rail, wherein the system of inductors and quenching unit connected with the relevant mechanisms of manual installation alternately in the working position by the signal control unit. inducers system consists of two identical electrically connected inductors, and have the possibility of the synchronous rotation around its own axis by means of a lever mechanism for their fixation, with a predetermined abutment, in the heat-treatable zone of the welded joint in the working position, or dilution to the angle required for installation in the sprayer area, or for the removal of the thermally treating unit from the rail. Effective inductor design has improved the efficiency of the system, and thus reduce the frequency converter power to 75 kW while maintaining heating time within 240 seconds. Quenching unit consisting of a sprayer, structurally combined with the quenching medium supply system mounted on the cantilever arm rotatably about a horizontal axis by means of a lever mechanism for its fixation in the vertical (transport) or in a horizontal (operating) position on the rail; and as the quench medium using compressed air. The unit has low weight and overall dimensions, has the ability to manually move a machine on the track rail whip, with a possibility of free movement along the rail lashes. Significantly reduced cost of installation and maintenance costs, while improving the quality of heat treatment of weld joints of the rails, compared with the known installation.
