Description
Technical Field
The utility model belongs to the railway switch rail is reinforceed and is restoreed the field, relates to one kind and reinforceed on line in rail surface and prosthetic portable online processing apparatus, specifically is a rail surface online mobile processing apparatus based on laminar flow plasma.
Background
The rail transit is an important traffic facility related to the national civilization, and the steel rail is an important component of the rail transit. As train speeds, capacity and axle weights increase, the quality and service life of the rails also become of particular importance. In the running process of a train, a steel rail directly bears the load of the train and guides wheels to run, and the steel rail is seriously worn by the double actions of impact and friction of the wheels, particularly small-radius curve tracks, turnouts, switch rails and the like. How to improve the service life of the steel rail becomes one of the keys for reducing the railway operation cost and improving the railway operation efficiency.
In order to prolong the service life of the railway steel rail, three methods are generally adopted at home and abroad: firstly, obtaining a fine lamellar pearlite structure by adopting an induction full-length quenching process; secondly, replacing common carbon steel with low-alloy high-carbon steel; thirdly, bainite steel or low-carbon martensite steel is adopted to replace high-carbon steel, so that the surface hardness and the like of the steel rail are further improved. In the past years, the full-length rail quenching technology has achieved remarkable effects, and the wear resistance of the rail is respectively improved by 50% (straight track) and 100% (curved track). However, the main disadvantage of the full-length quenching technology is that the surface of the steel rail cannot have martensite or even bainite structures, otherwise, the fracture toughness of the steel rail is greatly reduced, so that accidents such as rail breakage and the like occur in the service process of the steel rail, and the safe operation of the railway is seriously influenced. Therefore, the hardness of the steel rail after full-length quenching is generally controlled to be between Hv320 and 390, and the excavation of the wear resistance potential is close to the limit. The low-alloy high-carbon steel rail is combined with the full-length quenching technology, so that the wear resistance of the rail can be further improved, but the effect is not obvious. The low-carbon martensite steel rail and the bainite steel rail are still in the research and development stage, and the main difficulty is how to ensure the strength of the welding joint of the steel rail.
The laser surface strengthening technology is one of the metal material surface strengthening technologies which are developed rapidly in the last two decades, comprises the technologies of laser phase change quenching, fused quenching, surface alloying, surface cladding and the like, and has the common characteristics of high heating speed, small heat affected zone and small workpiece deformation, so that the laser surface strengthening technology is expected to replace an induction full-length quenching technology and becomes a new generation of steel rail surface strengthening technology. The early research results show that the toughness of the steel rail can not be obviously reduced even if the surface of the steel rail has a martensite structure due to the characteristics of high heating speed, high cooling speed, limited depth of a hardened layer, a state of compressive stress of the hardened layer and the like of the laser surface strengthening technology. Particularly, the hardness of the martensite structure is obviously higher than that of the fine lamellar pearlite, so that the upper limit that the surface hardness of the steel rail cannot be higher than Hv390 in the induction full-length quenching process can be broken through, and the surface wear resistance of the steel rail is improved by a new step. In addition, the laser surface quenching technology has the characteristics of convenient regulation and control of depth of a hardened layer, no need of quenching medium, no need of tempering, small deformation of a workpiece and the like, so that fixed-point processing can be realized in a production workshop, special mobile equipment can be expected to be developed, the equipment can be carried to a railway site, and the on-line quenching of a track can be completed on the premise of not disassembling a steel rail.
Obviously, in consideration of the current situation that the railway trunk line is busy, the mobile laser processing device for on-line processing has high maneuverability, and can realize the surface strengthening and toughening and repairing treatment of the steel rail on the premise of not influencing the normal operation of the train as much as possible.
In the report of the Chinese invention patent document "an online laser processing device for rail surface toughening treatment" (publication number is CN101240367, published as 2008, 08 and 13), an online laser processing device for rail surface toughening treatment is provided, which can complete the laser phase change quenching, fused quenching, alloying and cladding treatment of various rails including a head rail, a bend, a guard wheel rail, a turnout and the like without dismounting the rail and influencing the normal operation of a train, thereby realizing the online strengthening and repairing of the rail. The laser processing equipment is divided into a laser processing vehicle and a power system container. The laser processing vehicle comprises a motion executing mechanism, a laser processing head, a light guide system and a control system, wherein the motion executing mechanism is arranged on a moving trolley; the laser processing vehicle adopts a three-wheel structure, one side of two wheels is provided with a laser processing head, and a light path light inlet of the laser processing head is directly connected with a fiber laser on the container of the power system by adopting a transmission fiber. During actual processing, the laser processing vehicle moves forward along the track direction under the control of the control system, the laser beam is guided to the surface of the steel rail under the action of the light guide system, and the motion executing mechanism drives the laser processing head to swing left and right, so that laser strengthening and repairing processing on the surface of the steel rail is realized. After the laser processing vehicle processes the rail on one side, the laser processing vehicle needs to be turned around and reversed, and laser strengthening and repairing treatment is carried out on the rail on the other side.
The main disadvantages of the laser processing vehicle proposed in the above patent document are that the processing efficiency is low, the laser processing vehicle can only perform laser strengthening and repairing treatment on a single-side steel rail at a time, after one side is finished, the laser processing vehicle needs to be turned around and reversed, and then the other side is processed, which takes a long time, and seriously affects the processing efficiency when the laser processing is actually performed on the steel rail.
