Problems solved by technology

However, the main disadvantage of the full-length quenching technology is that martensite or even bainite structure cannot appear on the surface of the rail, otherwise the fracture toughness of the rail will be greatly reduced, resulting in accidents such as rail breakage during the service process, seriously Affect the safe operation of the railway

Abstract

The invention discloses an online double-station mobile-type laser processing device for strengthening, toughening and repairing the surface of a steel rail by lasers. The online double-station mobile-type laser processing device particularly comprises a double-station mobile-type laser processing device, two sets of laser processing heads, two sets of laser beam motion actuating mechanisms, a control system and a laser guiding system. The mobile-type laser processing device of the invention has the advantages of small size and light weight, so the mobile-type laser processing device is suitable for manual transportation; by using the dedicated control system, the control is convenient; the operation can be conducted during the 'skylight' time for rail overhaul, particularly, the mobile-type laser processing device can simultaneously strengthen, toughen and repair various parts of the surfaces of linear steel rails, curved steel rails, guard rails, turnout junction and other double rails, more particularly, the rails are subjected to laser phase-change quenching, laser surface-melting quenching, laser cladding, laser alloying, laser texturing, laser shock processing and other treatment, thus greatly increasing the abrasion resistance of the strengthened steel rails. The online double-station mobile-type laser processing device has the characteristics of high processing efficiency, high portability, high processing accuracy and easy control.

Description

technical field [0001] The invention belongs to the category of surface strengthening and repairing, and relates to a mobile laser processing device for on-line strengthening and toughening treatment and repairing of rail surfaces, which is suitable for strengthening and toughening treatment and repairing of rail surfaces for rail transportation such as railways, subways and light rails. Background technique [0002] Rail transit is an important transportation facility related to the national economy and people's livelihood, and rails are an important part of rail transit. With the increase of train speed, capacity and axle load, the quality and service life of rails have become particularly important. During the operation of the train, the rail directly bears the load of the train and guides the running of the wheels. Due to the dual effects of impact and friction of the wheels, the wear is very serious, especially on small-radius curved tracks, turnouts, and point rails. ...
